Description

本発明は、水分を含有する汚泥等より構成される小片化された粘性物を改良材と混練すると共に粒状に解砕して改良土として処理するための混練解砕装置であって、特に水分を含有する汚泥等より構成される小片化された粘性物と改良材との混合状態が均一であると共に所望の大きさや形状の粒状になった良好な改良土を得ることができる混練解砕装置に関するものである。   The present invention is a kneading and pulverizing apparatus for kneading a fragmented viscous material composed of water-containing sludge and the like with an improving material and pulverizing it into granules and treating it as improved soil. Kneading and crushing apparatus capable of obtaining a good improved soil in which the mixed state of the fragmented viscous material composed of sludge and the like and containing the improved material is uniform and has a desired size and shape. It is about.

建設現場や道路・水道・ガス工事等で発生する建設汚泥,河川・湖沼やダム等の浚渫汚泥,コンクリート等に使用される骨材を生産する際に洗浄排水から分離される汚泥,石等が多少混入した建設残土やこれらの汚泥等をシックナーやフィルタープレス等により含水率を調整した脱水ケーキ等の水分を含有する汚泥等より構成される粘性物(以下、単に「粘性物」という場合がある)は、脱水・乾燥等の処理が行われた後、又は脱水ケーキ等の如く或る程度含水率が低い場合にはそのままの状態で、一般に産業廃棄物として最終処分場等において廃棄処分されてきたのであるが、近年における最終処分場不足問題や環境問題等の産業廃棄物を取り巻く様々な問題により、これらの粘性物を産業廃棄物として廃棄処分することが困難となっており、これらの粘性物を再生資源として再利用する技術の開発が望まれていた。   Construction sludge generated at construction sites, roads, waterworks, gas construction, dredged sludge from rivers, lakes, dams, etc., sludge, stones, etc. separated from washing wastewater when producing aggregates used for concrete, etc. Soil mixed with a little bit of construction residue or sludge such as dehydrated cake whose moisture content is adjusted by thickener or filter press, etc. (hereinafter sometimes referred to simply as “viscous material”) ) Is generally disposed of as industrial waste at the final disposal site after treatment such as dehydration and drying, or when the moisture content is low to some extent, such as dehydrated cake. However, due to various problems surrounding industrial waste such as shortage of final disposal sites and environmental problems in recent years, it has become difficult to dispose of these viscous materials as industrial waste. , Development of technologies for reusing these gum as recyclable resources has been desired.

そこで、本出願人は、前記したような粘性物に、セメント,生石灰,消石灰,水砕,フライアッシュ(飛灰),石粉,高砕スラグや石膏ボード粉砕粉等の改良材を混入すれば、例えば下層複合路盤材,埋戻し材,覆土材,細骨材やエコセメント原料等の改良土として好適に使用できると考えたが、粘性物が塊状の状態では改良材との混合状態が均一である良好な改良土を得ることが困難であるので、粘性物を細かく切り出して小片化しその表面積を増加させた状態で改良材を混入して混練すれば改良材との混合状態が均一である良好な改良土を得ることできると考えた。   Therefore, if the present applicant mixes an improved material such as cement, quick lime, slaked lime, water granulated, fly ash (fly ash), stone powder, highly crushed slag or gypsum board pulverized powder into the viscous material as described above, For example, we thought that it could be used suitably as improved soil for lower composite roadbed materials, backfill materials, covering materials, fine aggregates, and raw materials for eco-cement. However, when the viscous material is in a lump, the mixed state with the improved material is uniform. Since it is difficult to obtain a certain improved soil, if the improved material is mixed and kneaded in a state where the viscous material is cut out into small pieces and the surface area is increased, the mixed state with the improved material is uniform. I thought it would be possible to obtain an improved soil.

そして、本出願人は、このように粘性物を細かく切り出して小片化する装置として、底板上に回転自在に立設せしめられている円筒状の回転体と、この回転体の周壁の外面を案内せしめる案内機構と、この回転体をその軸心を中心に回転せしめる回転機構と、前記底板にこの回転体の回転中心から一方の側に設けられている排出口からこの回転体内に臨ませた刃先がこの回転体の回転に伴いこの刃先に向かって回転移動してくる粘性物を総て切り下げる方向で切断するように回転せしめられる切出刃と、その端縁がこの排出口の一方の側縁との間で回転体の回転に伴って移動してくる粘性物に対向して挿入口を開口せしめられており回転体内に臨ませた切出刃の刃先を覆う切出刃カバーとを備えている切出装置を提案すると共に、この切出装置より排出される小片化された水分を含有する汚泥等より構成される粘性物(以下、単に「小片化された粘性物」という場合がある)とホッパーより投入される改良材とを一般に使用されている混練機、具体的には小片化された粘性物と改良材とを混練すると共にこの混練機の排出口側に順次送るためのパドルがそれぞれ放射状に且つ軸方向に所定の間隔毎に設けられている平行な2本の軸と、これらの軸を回転せしめるための回転駆動機構とが設けられている従来より原料と添加材とを混練するために一般に使用されているパドル式の混練機により混練して改良土とする技術を提案した(例えば、特許文献1参照。)。   As a device for finely cutting out the viscous material in this way, the applicant of the present invention guides a cylindrical rotating body that is rotatably installed on the bottom plate and an outer surface of the peripheral wall of the rotating body. A guiding mechanism for rotating, a rotating mechanism for rotating the rotating body around its axis, and a cutting edge that faces the rotating body from a discharge port provided on one side of the bottom plate from the rotation center of the rotating body Is a cutting blade that is rotated so as to cut all the viscous materials that rotate and move toward the cutting edge in accordance with the rotation of the rotating body, and its edge is connected to one side edge of the discharge port. A cutting blade having a cutting blade cover that covers the cutting edge of the cutting blade that faces the viscous material that moves with the rotation of the rotating body and opens the insertion port. Proposing a device and cutting out Generally used is a viscous material composed of sludge containing finely-divided water discharged (hereinafter sometimes simply referred to as “small-sized viscous material”) and an improved material introduced from the hopper. Kneaders, more specifically, paddles for kneading the crushed viscous material and the improved material and sequentially feeding them to the discharge port side of the kneader are provided radially at predetermined intervals in the axial direction. A paddle type kneader generally used for kneading raw materials and additives, conventionally provided with two parallel shafts and a rotation drive mechanism for rotating these shafts Proposed a technique for improving soil by kneading (see, for example, Patent Document 1).

しかしながら、前記したような切出装置により粘性物を小片化すると粘性物はその表面積が増加し改良材との混合状態が向上するものの、この切出装置により小片化された粘性物とホッパーより投入される改良材とを前記したような一般に使用されているパドル式の混練機で混練すると、粘性物の含水量が高い場合にはパドルで混練することにより粘性物は再び塊状となり、小片化された粘性物の内部にまで改良材が行き渡らないばかりか、混練機の内壁やパドル等に激しく付着すると共に、排出口の方向へ順次送ることが困難となってしまう欠点があり、また粘性物が塊状となってしまうと、粘性物の内部にまで改良材が行き渡っていないので所望の大きさや形状の粒状となった改良土を得ることが困難である欠点があり、そしてこの粘性物が塊状とならないようにするためには更に大量の改良材を投入しなくてはならないという欠点があり、更に改良材はホッパーにより投入するものであるから、連続的ではなく或る程度の塊の状態で断続的に混練室内に投入されるので、改良材の投入状態が均一ではなく小片化された粘性物と改良材との混合状態が均一である良好な改良土を得ることできないという欠点があった。   However, when the viscous material is fragmented by the cutting device as described above, the surface area of the viscous material increases and the mixing state with the improving material is improved. However, the viscous material fragmented by this cutting device and the hopper are charged. When the water content of the viscous material is high, the viscous material is again agglomerated and crushed by kneading with the paddle when the moisture content of the viscous material is high. In addition to the fact that the improved material does not reach the inside of the viscous material, it has the disadvantage that it adheres violently to the inner wall and paddle of the kneading machine and it becomes difficult to send it in the direction of the discharge port. If it becomes a lump, there is a drawback that it is difficult to obtain improved soil in the form of granules of the desired size and shape because the improving material does not reach the inside of the viscous material, and this viscosity In order to prevent the material from becoming agglomerated, there is a disadvantage that a larger amount of the improving material must be added. Further, since the improving material is supplied by a hopper, a certain amount of the lump is not continuous. Since the material is intermittently charged into the kneading chamber in a state, the improved material is not uniformly charged, and there is a drawback that it is not possible to obtain a good improved soil in which the mixed state of the fragmented viscous material and the improved material is uniform. there were.

そこで、このような切出装置により小片化された粘性物と改良材とを混練する混練機として、例えば層状に装入された前記ケーキを移動させる連続移動床式コンベアと、前記コンベアの上方に配設された複数の回転チョッパーであって長さ方向が前記コンベアの移動方向に対して直角方向に軸芯が向いているローター軸の周囲に当該ローター軸の方向に対して直角に固定された状態で前記ローターの回転と共に回転可能なチョッパーを備えている装置と、そのコンベア上方をライン方向に移動し得るクレーンに装着された改良材用のフレコン受ホッパーとから構成される装置(例えば、特許文献2参照。)を用いて、このような混練機のコンベアの上流側の上方より小片化された粘性物を、そしてフレコン受ホッパーより改良材を投入して混練することが考えられる。   Therefore, as a kneading machine for kneading the viscous material fragmented by the cutting device and the improving material, for example, a continuous moving floor type conveyor for moving the cake loaded in layers, and above the conveyor A plurality of rotary choppers arranged and fixed at a right angle to the direction of the rotor shaft around the rotor shaft whose length direction is perpendicular to the moving direction of the conveyor. A device comprising a chopper that can rotate with the rotation of the rotor in a state and a flexible container receiving hopper for improvement material mounted on a crane that can move in the line direction above the conveyor (for example, a patent (Refer to Document 2)), the viscous material fragmented from the upper upstream side of the conveyor of such a kneader and the improved material from the flexible container receiving hopper are added and mixed. It is conceivable to.

しかしながら、この混練機では改良材はコンベアベルト上方をライン方向に移動し得るクレーンに装着された改良材用のフレコン受ホッパーより投入されるものであるから、コンベアベルトの上流側の上方より投入される小片化した粘性物同士はコンベア上で直接触してしまい、折角切出装置により小片化されても結局コンベア上で層を成して再び塊状になってしまうので、このような塊状の状態になった粘性物にフレコン受ホッパーより改良材を投入してチョッパーを回転させることにより混練したとしても、所望の大きさや形状の改良土を得ることが困難であるという欠点があり、また改良材は連続的ではなく或る程度の塊の状態で断続的に混練室内に投入されるので、改良材の投入状態が均一ではなく小片化された粘性物と改良材との混合状態が均一である良好な改良土を得ることができないという欠点があった。 However, in this kneader, the improved material is fed from the flexible container receiving hopper for the improved material mounted on the crane that can move in the line direction above the conveyor belt. that small pieces with viscous product each other will be come in contact directly on the conveyor, so it becomes again in layers on eventually be small pieces conveyor bulk by much trouble cutting device, such massive Even if a kneaded material is added to the viscous material in the state of the flexible container receiving hopper and kneaded by rotating the chopper, there is a disadvantage that it is difficult to obtain an improved soil of the desired size and shape. Since the material is intermittently charged into the kneading chamber in a certain lump state rather than continuously, the improved material is not uniformly charged, and the viscous material and the improved material Mixed state has a drawback that it is impossible to obtain a good modified soil is uniform.

特許第3270391号明細書Japanese Patent No. 3270391 特開2001−852号公報JP 2001-852 A

本発明は、前記従来技術の欠点を解消し、水分を含有する汚泥等より構成される小片化された粘性物を改良材と混練すると共に粒状に解砕して改良土へと処理するための混練解砕装置であって、特に水分を含有する汚泥等より構成される小片化された粘性物と改良材との混合状態が均一であると共に所望の大きさや形状の粒状になった良好な改良土を得ることができる混練解砕装置を提供することを課題とする。   The present invention eliminates the drawbacks of the prior art and is for kneading a fragmented viscous material composed of water-containing sludge and the like with an improving material and pulverizing it into a granulated material for processing into improved soil. A kneading and pulverizing device, particularly a good improvement in which the mixed state of the crushed viscous material composed of water-containing sludge and the like is uniform and the desired size and shape are formed into granules. It is an object of the present invention to provide a kneading and pulverizing apparatus capable of obtaining soil.

本発明者らは前記課題を解決すべく鋭意研究の結果、解砕混練室のその一部又は全部が幅方向が上方に円弧を成すように着脱自在に設置されている可撓性シートで構成されている天井材に開口した投入口からコンベア上の上流側へ投入される小片化された粘性物に向けて開口した噴霧口より改良材を解砕混練室内に霧状に拡散させると共に、コンベアの上方に上流側の中間近傍から下流側にかけて設けられコンベアの移送方向と反対方向になるように回転する複数の混練解砕刃によりコンベア上を移送されてくる粘性物を改良材と混練すると共に粒状に解砕すれば、小片化された粘性物はその表面に全体的に改良材が付着した状態でコンベア上の上流側に投入されるから、小片化された粘性物は改良材と効率良く混合できると共にコンベア上で小片化された粘性物同士は付着した改良材を介して接触するのでコンベア上で再び塊状になることがなく、また解砕混練室内は霧状に噴霧された改良材が浮遊した雰囲気となっているから、コンベア上を移送してくる改良材が付着した粘性物はコンベアの移送方向と反対方向になるように回転する混練解砕刃の回転力によって解砕されてコンベアの上流方向に押し飛ばされた際に解砕混練室内に浮遊する改良材と接触して、この押し戻された粘性物の表面には再度改良材が付着し更に混合を促進させることができるので、小片化された粘性物と改良材との混合状態が均一であると共に所望の大きさや形状の粒状になった良好な改良土を得ることができ、また解砕混練室の天井材の一部又は全部が幅方向が上方に円弧を成すように着脱自在に設置されている可撓性シートで構成されているので、天井材が平面を成しているのと比較して跳ね上げられた粘性物が付着し難いばかりでなく可撓性シートは着脱自在に設置されているので可撓性シートを取り外すことにより解砕混練室内の混練解砕手段やコンベア等の保守・点検等が簡単にできることを究明して本発明を完成したのである。 As a result of diligent research to solve the above problems, the present inventors have constituted a flexible sheet in which part or all of the crushing and kneading chamber is detachably installed so that the width direction forms an arc upward. The improvement material is diffused in the pulverization and kneading chamber in the form of a mist from the spray port opened toward the fragmented viscous material charged to the upstream side of the conveyor from the input port opened to the ceiling material, and the conveyor And kneading the viscous material transferred on the conveyor with the improving material by a plurality of kneading and crushing blades that are provided from the middle of the upstream side to the downstream side and rotate so as to be opposite to the transfer direction of the conveyor. If it is crushed into granules, the crushed viscous material is thrown into the upstream side of the conveyor with the improved material adhering to the entire surface. Can be mixed and on the conveyor The fragmented viscous materials come into contact with each other through the adhering improved material, so that they do not become agglomerate again on the conveyor, and the pulverized kneading chamber has an atmosphere in which the improved material sprayed in a mist form floats. Therefore, the viscous material with the improved material transferred on the conveyor is crushed by the rotational force of the kneading crushing blade rotating in the direction opposite to the conveyor transfer direction and pushed away in the upstream direction of the conveyor. The improved material floating in the crushing and kneading chamber is contacted with the improved material, and the improved material adheres again to the surface of the pushed-back viscous material, so that further mixing can be promoted. Can be obtained in a uniform state with a desired size and shape, and part or all of the ceiling material of the crushing and kneading chamber has an upward width direction. Removable to form a circular arc Because it is composed of a flexible sheet that is placed, it is not only difficult for sticking up the sticking-up viscous material compared to the case where the ceiling material is flat, but the flexible sheet is also detachable The present invention was completed by investigating that the maintenance and inspection of the kneading and crushing means and the conveyor in the crushing and kneading chamber can be easily performed by removing the flexible sheet .

即ち本発明は、上流側上方より水分を含有する汚泥等より構成される小片化された粘性物が投入され下流側より粒状になった改良土を排出させるコンベアと、該コンベアの上方に上流側の中間近傍から下流側にかけて複数設けられており該コンベアの長手方向と略直角な方向にその軸心を有し回転自在に軸支されている回転軸の側面より突設された複数の混練解砕刃を回転軸駆動手段により該コンベア上の粘性物を該コンベアによる移送方向と反対方向に押し飛ばすように回転させる混練解砕手段と、該コンベアの上流側の端縁近傍から下流側の端縁近傍にまで亘って該コンベアの長手方向の両端縁近傍より略鉛直に立設されている一対の側壁と、該両側壁の上流側の側縁間に立設されている上流壁と、該両側壁の上縁と上流壁の上縁とにその端縁を連結されて該コンベアの上方を覆っておりその上流側には小片化された粘性物を該コンベア上面に投入するための投入口が開口しその一部又は全部が幅方向が上方に円弧を成すように着脱自在に設置されている可撓性シートで構成されている天井材とを備えた解砕混練室と、
該解砕混練室内の投入口近傍へ改良材を供給するスクリューフィーダと、円筒状を成し該投入口より投入される小片化された粘性物に向けて開口した噴霧口が側面に形成され該スクリューフィーダの吐出口の下方に設けられている噴霧筒と、該噴霧筒の下方に該噴霧筒と僅かに隙間を空けて設置され上面に複数の凸条部が設けられている円盤と、該円盤を高速回転させる円盤駆動手段とから成り、該円盤の回転力によって改良材を該噴霧筒の噴霧口より解砕混練室内に霧状に拡散させる改良材供給噴霧手段とから構成されていることを特徴とする混練解砕装置である。
That is, the present invention provides a conveyor for discharging the improved soil that has been made into small pieces of viscous material composed of water-containing sludge from the upstream side and granulated from the downstream side, and the upstream side above the conveyor. A plurality of kneading solutions provided from the side surface of the rotating shaft that is provided rotatably from the middle to the downstream side and has its axis in a direction substantially perpendicular to the longitudinal direction of the conveyor and is rotatably supported. Kneading and crushing means for rotating the crushing blade so that the viscous material on the conveyor is pushed away in the direction opposite to the transfer direction by the conveyor by the rotary shaft driving means, and the downstream end from the vicinity of the upstream edge of the conveyor A pair of side walls erected substantially vertically from the vicinity of both end edges in the longitudinal direction of the conveyor to the vicinity of the edges, an upstream wall erected between the side edges on the upstream side of the both side walls, The upper edge of both side walls and the upper edge of the upstream wall Is connected to edge into the slot is open partially or entirely in the width direction above for the small pieces are viscous product at its upstream side covers over the said conveyor is put into the conveyor upper surface A crushing and kneading chamber provided with a ceiling material composed of a flexible sheet that is detachably installed to form an arc ;
A screw feeder that supplies an improved material to the vicinity of the charging port in the pulverization and kneading chamber, and a spray port that is formed in a cylindrical shape and opens toward a fragmented viscous material charged from the charging port is formed on the side surface. A spray cylinder provided below the discharge port of the screw feeder, a disk provided with a plurality of ridges on the upper surface provided with a slight gap between the spray cylinder and the spray cylinder; and A disk drive means for rotating the disk at a high speed, and constituted by an improved material supply spray means for diffusing the improved material into the pulverization kneading chamber from the spray port of the spray cylinder by the rotational force of the disk. A kneading and pulverizing apparatus characterized by the above.

そして、解砕混練室の一対の側壁,上流壁及び天井材の内面が小片化された水分を含有する汚泥等より構成される粘性物との摩擦が小さい低摩擦材料で形成されていれば、混練解砕刃によって跳ね上げられた粘性物が解砕混練室の内面へ付着するのを最小限に防止することができて好ましく、また解砕混練室の天井材を間欠的に打撃して該天井材の内面に付着した粘性物をコンベア上に落下させるための打撃装置が更に設けられていれば、天井材に付着してしまった粘性物を解砕混練室から天井材を取り外すことなく除去できるので好ましいことも究明したのである。 And if the friction between the pair of side walls of the pulverization kneading chamber, the upstream wall and the ceiling material is made of a low friction material having a small friction with a viscous material composed of sludge containing moisture, preferably it can be prevented to minimize the viscous substance thrown up by kneading solution cracking blades are attached to the inner surface of the solution砕混kneading chamber, and intermittently strike the ceiling material or solutions砕混kneading chamber If a striking device is further provided for dropping the viscous material adhering to the inner surface of the ceiling material onto the conveyor, the viscous material adhering to the ceiling material can be removed without removing the ceiling material from the crushing and kneading chamber. It has also been determined that it can be removed.

また、改良材供給噴霧手段が解砕混練室内の投入口近傍であってコンベアによる移送方向の最も上流側に設けられていれば、改良材供給噴霧手段の噴霧筒の噴霧口より噴霧される改良材が解砕混練室全体に霧状に拡散され易いので好ましく、また改良材供給噴霧手段の円盤の凸条部が該円盤の中心より放射方向に複数設けられていれば、より確実に且つ広範囲に改良材を解砕混練室内に霧状に拡散させることができて好ましいことも究明したのである。   Further, if the improved material supply spray means is provided in the vicinity of the inlet in the crushing and kneading chamber and provided at the most upstream side in the transfer direction by the conveyor, the improvement sprayed from the spray port of the spray cylinder of the improved material supply spray means It is preferable because the material is easy to be diffused in the form of a mist in the entire crushing and kneading chamber, and it is more reliable and wide-ranging if a plurality of ridges of the disk of the improved material supply spray means are provided in the radial direction from the center of the disk It was also found that the improved material can be diffused in the pulverization and kneading chamber in a mist state.

更に、解砕混練室の混練解砕刃が回転軸の外周に該回転軸と平行にその軸心を枢支された複数の混練解砕刃支持軸に回転自在に軸支されている混練解砕刃であれば、粘性物に石等が多少混入してたとしても混練解砕刃や回転軸駆動手段等を破損させてしまうことを最小限に防止できるので好ましく、またコンベアの移動速度及び/又は混練解砕刃駆動手段の回転速度が調整可能であれば、これらの速度を調整するという簡単な操作だけで様々な大きさや形状の改良材を得ることができて好ましいことも究明したのである。 Further, the kneading and crushing blade of the crushing and kneading chamber is rotatably supported by a plurality of kneading and crushing blade support shafts pivotally supported on the outer periphery of the rotating shaft in parallel with the rotating shaft. if cracking blades, the moving speed of preferably can be prevented to a minimum that the stones or the like resulting in defeat the kneading solution cracking blades and rotary shaft drive means or the like even though slightly mixed in the viscous material, also conveyor It was also found that if the rotational speed of the kneading and crushing blade driving means can be adjusted, it is possible to obtain improved materials of various sizes and shapes by a simple operation of adjusting these speeds. It is.

本発明に係る混練解砕装置は、前記した構成より成るものであるから、小片化された粘性物と改良材との混合状態が均一であると共に所望の大きさや形状の粒状になった良好な改良土を得ることができるばかりでなく、改良材供給噴霧手段により小片化された粘性物はその表面に全体的に改良材が付着した状態でコンベア上の上流側に投入されると共に、解砕混練室内は霧状に噴霧された改良材が浮遊した雰囲気となっているのでコンベアの上流側から投入されてコンベア上を移送される間や複数の混練解砕刃により上流側へ押し飛ばされている間にも改良材が再付着したりするため全体的に改良材がより均一に混合するのであり、その結果コンベアから排出されるまでの間に改良材が粘性物中の水分と確実に反応して所望の強度を有する大きさや形状の粒状になった良好な改良土を得ることができるので、改良材を無駄にすることがないと共に粘性物を品質が一定で良好な粒状の改良土へと処理する効率を飛躍的に向上させることができ、また混練解砕刃の数や形状,回転軸の数や位置,コンベアの長さ等を適宜変更することにより、様々な用途に使用することができる様々な大きさ、形状や強度の良質な改良材を得ることができるのであり、更に解砕混練室の天井材の一部又は全部が幅方向が上方に円弧を成すように着脱自在に設置されている可撓性シートで構成されているので、その内面へ跳ね上げられた粘性物が付着するのを最小限に防止することができるばかりでなく、可撓性シートは着脱自在に設置されているので可撓性シートを取り外すことにより解砕混練室内の混練解砕手段やコンベア等の保守・点検等が簡単にできるのである。 Since the kneading and pulverizing apparatus according to the present invention is configured as described above, the mixing state of the fragmented viscous material and the improving material is uniform, and the desired size and shape of the granule are good. Not only can the improved soil be obtained, but the viscous material fragmented by the improved material supply spraying means is put on the upstream side of the conveyor with the improved material attached to the entire surface and crushed. Since the improvement material sprayed in the form of a mist is floating in the kneading chamber, it is thrown away from the upstream side of the conveyor and transported on the conveyor or pushed upstream by a plurality of kneading and crushing blades. As a result, the improved material re-adheres while it is mixed, so that the improved material is mixed more uniformly as a whole. As a result, the improved material reliably reacts with moisture in the viscous material before being discharged from the conveyor. Large with the desired strength Since it is possible to obtain a good improved soil in the shape of a sheath, the improvement material is not wasted and the efficiency of processing the viscous material into the improved improved granular shape with constant quality is dramatically improved. Various sizes and shapes that can be used for various purposes by appropriately changing the number and shape of kneading and crushing blades, the number and position of rotating shafts, the length of conveyors, etc. Nodea is, flexibility, which is installed detachably to further some or all the width direction of the ceiling material solutions砕混mixing chamber an arc upward can be obtained and high quality modifying material strength Since it is composed of a sheet, not only can the sticking up of the viscous material splashed on its inner surface be prevented to a minimum, but the flexible sheet is detachable so that it is flexible. Mixing in the crushing and kneading chamber by removing the sheet Maintenance and inspection such as crushing means and the conveyor is can be easy.

そして、解砕混練室の一対の側壁,上流壁及び天井材の内面が水分を含有する汚泥等より構成される小片化された粘性物との摩擦が小さい低摩擦材料で形成されていれば、その内面へ跳ね上げられた粘性物が付着するのを最小限に防止することができるばかりでなく、付着した粘性物が塊状に堆積してその重さが増加することによりコンベア上に落下して充分に改良材が混合されていない解砕混練処理の不完全な状態の改良土が排出されてしまう現象を防止することができて好ましく、更に解砕混練室の天井材を間欠的に打撃して天井材の内面に付着した粘性物をコンベア上に落下させるための打撃装置が更に設けられていれば、天井材に付着した粘性物を解砕混練室から天井材を取り外したり手等で打撃を加えることなく自動的に除去できるので好ましいのである。 Then, a pair of side walls of the solutions砕混kneading chamber, if the inner surface of the upstream wall and ceiling material is formed of a low friction material friction is small with small pieces are viscous product composed of sludge containing water, Not only can the sticking of the viscous material jumped to the inner surface be prevented to a minimum, but the attached viscous material will accumulate in a lump and drop on the conveyor as its weight increases. preferably it can be prevented a phenomenon that the modified soil incomplete state of sufficiently modifying material is not mixed solution砕混kneading process from being discharged, further to intermittently strike the ceiling material solutions砕混kneading chamber If a hammering device for dropping the viscous material adhering to the inner surface of the ceiling material onto the conveyor is further provided, the ceiling material can be removed from the crushing and kneading chamber by removing the ceiling material by hand Can be removed automatically without hitting Since it is preferred.

また、改良材供給噴霧手段が解砕混練室内の投入口近傍であってコンベアによる移送方向の最も上流側に設けられていれば、改良材供給噴霧手段の噴霧筒の噴霧口より噴霧される改良材が解砕混練室全体に霧状に拡散されて解砕混練室内でコンベア上に移送されてくる粘性物や複数の混練解砕刃により上流側へ押し飛ばされる粘性物に改良材が再付着し易い雰囲気となるので、小片化された粘性物と改良材との混合状態が向上して好ましく、また改良材供給噴霧手段の円盤の凸条部がその中心より放射方向に複数設けられていれば、より確実に且つ広範囲に改良材を解砕混練室内に霧状に拡散させることができるので、小片化された粘性物と改良材との混合状態が向上して好ましいのである。   Further, if the improved material supply spray means is provided in the vicinity of the inlet in the crushing and kneading chamber and provided at the most upstream side in the transfer direction by the conveyor, the improvement sprayed from the spray port of the spray cylinder of the improved material supply spray means The improved material is reattached to the viscous material which is diffused in the form of mist in the entire crushing and kneading chamber and transferred to the conveyor in the crushing and kneading chamber and to the viscous material which is pushed upstream by a plurality of kneading and crushing blades. Therefore, it is preferable that the mixed state of the fragmented viscous material and the improved material is improved, and a plurality of the protruding portions of the disk of the improved material supply spraying means are provided in the radial direction from the center. In this case, the improved material can be diffused in the pulverizing and kneading chamber more reliably and in a wide range, and therefore, the mixed state of the fragmented viscous material and the improved material is preferably improved.

更に、解砕混練室の混練解砕刃が回転軸の外周にその回転軸と平行にその軸心を枢支された複数の混練解砕刃支持軸に回転自在に軸支されている混練解砕刃であれば、粘性物に石等が多少混入していたとしても混練解砕刃がその石等に接触すると混練解砕刃が混練解砕刃支持軸を中心として接触を継続しない方向に回転するので混練解砕刃や回転軸駆動手段等を破損させてしまうことを最小限に防止できるから、混練解砕刃や回転軸駆動手段等の寿命を長くできると共に石等が多少混入した粘性物であっても対処することができるので好ましく、またコンベアの移動速度及び/又は混練解砕刃駆動手段の回転速度が調整可能であれば、これらの速度を調整するという簡単な操作だけで様々な大きさや強度の改良材を得ることができるばかりでなく、これらの速度を調整するという簡単な操作だけで、小片化された粘性物の水分含有量や気候条件等に左右されることなく、安定した品質の改良土を得ることができて好ましいのである。   Further, the kneading and crushing blade of the crushing and kneading chamber is rotatably supported by a plurality of kneading and crushing blade support shafts pivotally supported on the outer periphery of the rotating shaft in parallel with the rotating shaft. If it is a crushing blade, even if stones etc. are mixed in the viscous material, if the kneading crushing blade comes into contact with the stone etc., the kneading crushing blade will not continue to contact around the kneading crushing blade support shaft. Since it rotates, it is possible to minimize the damage of the kneading and crushing blade and the rotary shaft drive means, so that the life of the kneading and crushing blade and the rotary shaft drive means can be prolonged and the viscosity is mixed with some stones etc. Even if it is a thing, it is preferable because it is possible to cope with it, and if the moving speed of the conveyor and / or the rotational speed of the kneading and crushing blade driving means can be adjusted, various operations can be performed by a simple operation of adjusting these speeds. We can only get improved materials of a certain size and strength In addition, the simple operation of adjusting these speeds is preferable because stable soil with improved quality can be obtained without being affected by the moisture content of crushed viscous materials, climatic conditions, etc. is there.

Hereinafter, the kneading and crushing apparatus according to the present invention will be described in detail with reference to the drawings.

FIG. 4 is an enlarged sectional view taken along the line BB of FIG. 3, and FIG. 5 is another embodiment of the kneading and pulverizing means of the kneading and pulverizing apparatus according to the present invention. It is front explanatory drawing of an example.

図面中、1は上流側より水分を含有する汚泥等より構成される小片化された粘性物が投入され下流側より粒状になった改良土を排出させるコンベア1aと、このコンベア1aの上方に上流側の中間近傍から下流側にかけて複数設けられておりコンベア1aの長手方向と略直角な方向にその軸心を有し回転自在に軸支されている回転軸1baの側面より突設された複数の混練解砕刃1bbをコンベア1a上の粘性物をコンベア1aによる移送方向と反対方向になるように回転軸駆動手段1bcにより回転させる混練解砕手段1bと、コンベア1aの上流側の端縁近傍から下流側の端縁近傍にまで亘ってコンベア1aの長手方向の両端縁近傍より略鉛直に立設されている一対の側壁1c,1cと、両側壁1c,1cの上流側の側縁間に立設されている上流壁1dと、両側壁1c,1cの上縁と上流壁1dの上縁とにその端縁を連結されてコンベア1aの上方を覆っておりその上流側には小片化された粘性物をコンベア1a上面に投入するための投入口1eaが開口した天井材1eとを備えた解砕混練室であり、小片化された粘性物と後述する改良材供給噴霧手段2により噴霧される改良材とを混練すると共に粒状に解砕して改良土へと処理する役目を果たす。   In the drawing, reference numeral 1 denotes a conveyor 1a that discharges the improved soil that has been made into small pieces of viscous material composed of water-containing sludge from the upstream side and granulated from the downstream side, and upstream above the conveyor 1a. A plurality of protrusions are provided from the side surface of the rotary shaft 1ba that is provided in a plurality from the middle of the side to the downstream side and has its axis in a direction substantially perpendicular to the longitudinal direction of the conveyor 1a and is rotatably supported. From the vicinity of the upstream edge of the conveyor 1a, the kneading and crushing blade 1bb is rotated by the rotating shaft drive means 1bc so that the viscous material on the conveyor 1a is in the direction opposite to the transfer direction by the conveyor 1a. Stands between a pair of side walls 1c and 1c that are erected almost vertically from the vicinity of both end edges in the longitudinal direction of the conveyor 1a up to the vicinity of the downstream edge and the upstream side edge of both side walls 1c and 1c. The upstream wall 1d, the upper edges of the side walls 1c, 1c and the upstream wall 1d And a ceiling member 1e having an inlet 1ea for opening a piece of viscous material on the upper surface of the conveyor 1a. The crushing and kneading chamber serves to knead the crushed viscous material and the improved material sprayed by the improved material supply spraying means 2 to be described later and to disintegrate it into granules and process it into improved soil.

この解砕混練室1の下方には、図1に示す如く上流側より水分を含有する汚泥等より構成される小片化された粘性物が投入され下流側より粒状になった改良土を排出させるコンベア1aがあり、このコンベア1aは解砕混練室1の天井材1eの上流側に開口した投入口1eaよりコンベア1a上の上流側に投入される小片化した粘性物を、その上流側の中間近傍から下流側にかけて複数設けられている混練解砕手段1bへ移送させ、混練解砕手段1bによって混練解砕処理されて粒状となった改良土をその下流側より排出する。   Below this crushing and kneading chamber 1, as shown in FIG. 1, a fragmented viscous material composed of sludge containing water is introduced from the upstream side, and the improved soil that has become granular from the downstream side is discharged. There is a conveyor 1a, and this conveyor 1a is used to remove a fragmented viscous material that is introduced upstream of the inlet 1ea on the conveyor 1a from an inlet 1ea that is opened upstream of the ceiling material 1e of the crushing and kneading chamber 1. A plurality of kneading and pulverizing means 1b are provided from the vicinity to the downstream side, and the improved soil that has been granulated and kneaded by the kneading and pulverizing means 1b is discharged from the downstream side.

このコンベア1a上の上流側に小片化された粘性物を投入するには、例えば図示しないが別途設置された切出装置等により小片化された粘性物をバケットコンベアやフード付コンベア等のコンベアによって移送することにより解砕混練室1の天井材1eの上流側に開口した投入口1eaへ投入してもよいが、図1に示す如く切出装置Kが解砕混練室1の天井材1eの上流側に開口した投入口1ea上に設けられていれば、この切出装置Kにより粘性物を小片化して直接投入口1eaへ投入することができるので、粘性物の小片化と粘性物の混練解砕とを一つの装置で処理することができて好ましい。   In order to put the viscous material fragmented on the upstream side of the conveyor 1a, for example, although not shown, the viscous material fragmented by a cutting device or the like separately installed is transferred by a conveyor such as a bucket conveyor or a hooded conveyor. Although it may be put into the inlet 1ea opened upstream of the ceiling material 1e of the crushing and kneading chamber 1 by being transferred, the cutting device K is connected to the ceiling material 1e of the crushing and kneading chamber 1 as shown in FIG. If it is provided on the inlet 1ea opened on the upstream side, the cutting device K can break down the viscous material and directly feed it into the inlet 1ea. It is preferable that the crushing can be processed by one apparatus.

そして、後述する改良材供給噴霧手段2によりその表面に全体的に改良材が付着した状態で小片化された粘性物が次々とコンベア1a上に投入されて積み重なった状態でコンベア1a上を移送されてくる粘性物は、このコンベア1a上を上流側から下流側へと移送されることにより改良材と粘性物に含有されている水分との充分な反応時間を得ることができるのである。   And, the improved material supply spray means 2 to be described later, the viscous material broken into small pieces with the improved material attached to the entire surface is successively put on the conveyor 1a and transferred on the conveyor 1a in a stacked state. The coming viscous material is transferred on the conveyor 1a from the upstream side to the downstream side, so that a sufficient reaction time between the improving material and the moisture contained in the viscous material can be obtained.

このコンベア1aとしては、粘性物や粒状となった改良土を移送できるように図1に示す如く一般的なベルトコンベア等が用いられるが、例えばコンベアの幅方向の端縁が幅方向の中央近傍よりも上方となるように移送面が構成されているベルトコンベアであれば、移送されてくる粘性物の水分含有量が高い場合において、粘性物がコンベアの移送面の端縁から漏れ出てしまうことを防止できるので好ましい。   As the conveyor 1a, a general belt conveyor or the like as shown in FIG. 1 is used so that viscous material or granular improved soil can be transferred. For example, the edge in the width direction of the conveyor is near the center in the width direction. In the case of a belt conveyor whose transfer surface is configured to be higher than the above, when the moisture content of the transferred viscous material is high, the viscous material leaks from the edge of the transfer surface of the conveyor. This is preferable because it can be prevented.

解砕混練室1のコンベア1aの上方の上流側の中間近傍から下流側には、コンベア1aの長手方向と略直角な方向にその軸心を有し回転自在に軸支されている回転軸1baの側面より突設された複数の混練解砕刃1bbをコンベア1a上の粘性物をコンベア1aによる移送方向と反対方向になるように回転軸駆動手段1bcにより回転させる混練解砕手段1bが複数設けられており、この混練解砕手段1bは、コンベア1aによる移送方向と反対方向になるように複数の混練解砕刃1bbを回転させることによって後述する改良材供給噴霧手段2によりその表面に全体的に改良材が付着した状態で小片化された粘性物が次々とコンベア1a上に投入されて複数積み重なった状態でコンベア1a上を移送してくる粘性物を、改良材と混練すると共に粒状に解砕して改良土へと処理するのである。   A rotating shaft 1ba that has a shaft centered in a direction substantially perpendicular to the longitudinal direction of the conveyor 1a and is rotatably supported from the vicinity of the upstream side of the upper side of the conveyor 1a in the crushing and kneading chamber 1 to the downstream side. A plurality of kneading and crushing means 1b for rotating a plurality of kneading and crushing blades 1bb projecting from the side of the conveyor 1a by rotating shaft driving means 1bc so that the viscous material on the conveyor 1a is in a direction opposite to the transfer direction by the conveyor 1a is provided. The kneading and pulverizing means 1b is entirely applied to the surface by the improved material supply spraying means 2 described later by rotating a plurality of kneading and pulverizing blades 1bb so as to be in the direction opposite to the transfer direction by the conveyor 1a. The viscous material that has been broken into pieces with the improved material attached to the conveyor 1a is successively put onto the conveyor 1a, and the viscous material transported on the conveyor 1a in a stacked state is kneaded with the improved material and dissolved into a granular form. Because it is crushed and processed into improved soil That.

この際に、コンベア1a上を移送してくる粘性物は、コンベア1aによる移送方向と反対方向になるように回転される混練解砕手段1bの混練解砕刃1bbの回転力によりその一部がコンベア1aの上流方向に押し飛ばされて粒状に解砕され、後述する改良材供給噴霧手段2により解砕混練室1内に霧状に浮遊する改良材と接触して、この押し飛ばされた粘性物の表面には再び改良材が更に付着しより均一に改良材と混合されるのである。   At this time, a part of the viscous material transported on the conveyor 1a is partly due to the rotational force of the kneading / disintegrating blade 1bb of the kneading / disintegrating means 1b rotated so as to be in the direction opposite to the conveying direction by the conveyor 1a. Viscosity that has been pushed away in the upstream direction of the conveyor 1a, crushed into granules, and brought into contact with the improvement material floating in a mist form in the crushing and kneading chamber 1 by the improvement material supply spraying means 2 described later. The improving material again adheres to the surface of the object and is mixed more uniformly with the improving material.

ここで、混練解砕手段1bがコンベア1aの上方の上流側の中間近傍から下流側に設けられているのは、解砕混練室1の投入口1eaよりその表面に全体的に改良材が付着した小片化された粘性物が次々とコンベア1aの上面の上流側に投入されて複数積み重なった状態の粘性物としてコンベア1a上をその上流側より移送されてくるが、粘性物がコンベア1aの上流側から上流側の中間近傍に設けられている混練解砕手段1bに至るまでの暫くの間、改良材と粘性物に含有されている水分とが反応する時間を得ることできるからあり、また混練解砕手段1bが複数設けられているのは、粘性物が混練解砕刃1bbと接触して解砕混練されたり上流側へと押し飛ばされたりする機会をなるべく多くして、改良材と粘性物に含有されている水分との反応状態が均一であると共に所望の大きさや形状の粒状になった良好な改良土を得るためである。   Here, the reason why the kneading and crushing means 1b is provided on the upstream side from the middle of the upstream side of the conveyor 1a is that the improving material adheres to the entire surface from the inlet 1ea of the crushing and kneading chamber 1. The crushed pieces of viscous material are successively fed to the upstream side of the upper surface of the conveyor 1a and transferred to the upstream side of the conveyor 1a as a plurality of stacked viscous materials. From time to time until the kneading and crushing means 1b provided in the vicinity of the middle of the upstream side, it is possible to obtain time for the moisture contained in the improved material and the viscous material to react, and kneading. The multiple crushing means 1b are provided because the opportunity for the viscous material to come into contact with the kneading crushing blade 1bb and be crushed and kneaded or pushed upstream is increased as much as possible, When the reaction state with moisture contained in the product is uniform In order to obtain a good modified soil became granular desired size and shape.

この混練解砕手段1bの混練解砕刃1bbとしては、例えば図1及び図2に示す如く回転軸1baの側面に板状を成した混練解砕刃1bbが法線方向に突設されているようなものであってもよいが、図5に示す如く解砕混練室1の混練解砕刃1bbが回転軸1baの外周に回転軸1baと平行にその軸心を枢支された複数の混練解砕刃支持軸1bdに回転自在に軸支されている混練解砕刃であれば、粘性物に石等が多少混入していた場合に石等と接触した混練解砕刃1bbが回転方向と逆方向に逃げることができるので混練解砕刃1bbや回転軸駆動手段1bc等を破損させてしまうことを最小限に防止できて、混練解砕刃1bbや回転軸駆動手段1bc等の寿命を長くできると共に石等が多少混入した粘性物であっても混練解砕することができるので好ましい。   As the kneading and crushing blade 1bb of the kneading and crushing means 1b, for example, as shown in FIGS. 1 and 2, a plate-like kneading and crushing blade 1bb is projected in the normal direction on the side surface of the rotating shaft 1ba. However, as shown in FIG. 5, a plurality of kneading and crushing blades 1bb of the crushing and kneading chamber 1 are pivotally supported on the outer circumference of the rotating shaft 1ba in parallel with the rotating shaft 1ba. If the kneading crushing blade is rotatably supported by the crushing blade support shaft 1bd, the kneading crushing blade 1bb that comes into contact with the stone or the like when the stone is mixed in the viscous material is Because it can escape in the opposite direction, it can prevent the kneading and crushing blade 1bb and the rotary shaft drive means 1bc from being damaged to the minimum, extending the life of the kneading and crushing blade 1bb and the rotary shaft drive means 1bc, etc. In addition, even a viscous material in which stones or the like are mixed is preferable because it can be kneaded and crushed.

即ち、このような回転軸1baの外周にこの回転軸1baと平行にその軸心を枢支された複数の混練解砕刃支持軸1bdに回転自在に軸支されている混練解砕刃1bbには、回転軸1baが回転駆動手段1bcに回転させられることにより回転軸1baの法線方向への遠心力が働くから、混練解砕刃1bbは回転軸1baの略法線方向へ姿勢が保持される状態となり、コンベア1a上を移送されてくる粘性物を解砕混練することができるが、コンベア1a上を移送されてくる粘性物に石等が混入していた場合においてこの混練解砕刃1bbによって混練解砕しようとすると、石等の自重が抵抗となり混練解砕刃1bbがコンベア1a上を移送されてくる粘性物と逆の方向に回転するため、この混練解砕刃1bbが石等と衝突する力を緩和されるのである。   That is, to the kneading and crushing blade 1bb rotatably supported by a plurality of kneading and crushing blade support shafts 1bd pivotally supported on the outer periphery of the rotating shaft 1ba in parallel with the rotating shaft 1ba. Since the rotary shaft 1ba is rotated by the rotation driving means 1bc, the centrifugal force in the normal direction of the rotary shaft 1ba acts, so that the kneading and crushing blade 1bb is held in the substantially normal direction of the rotary shaft 1ba. The viscous material transported on the conveyor 1a can be crushed and kneaded, but when the viscous material transported on the conveyor 1a is mixed with stones, etc. When the kneading and crushing is attempted, the weight of the stone or the like becomes resistance, and the kneading and crushing blade 1bb rotates in the opposite direction to the viscous material transferred on the conveyor 1a. The collision force is alleviated.

また、この混練解砕手段1bの混練解砕刃1bbが突設される回転軸1baを回転させる回転駆動手段1bcとしては、回転軸1baを回転させることができるように、回転軸1baに嵌着されたプーリとモータの回転軸に嵌着されたプーリとをベルトで連結してモータの回転駆動力を回転軸に伝達させるように構成されていてもよく、またそれぞれの回転軸1ba毎に別々のモータで回転駆動させるように構成されていたり、総ての回転軸1baを一つのモータで回転駆動させるように構成されていたりしてもよい。   Further, as the rotation driving means 1bc for rotating the rotary shaft 1ba on which the kneading / pulverizing blade 1bb of the kneading / pulverizing means 1b is projected, it is fitted to the rotary shaft 1ba so that the rotary shaft 1ba can be rotated. The pulley connected to the rotating shaft of the motor may be connected by a belt so that the rotational driving force of the motor is transmitted to the rotating shaft, and each rotating shaft 1ba is separately configured. The motor may be configured to be rotationally driven by a single motor, or the rotational shaft 1ba may be configured to be rotationally driven by a single motor.

更に、前記コンベア1aの移動速度及び/又は混練解砕刃駆動手段2dの回転速度が調整可能であれば、これらの速度を調整するという簡単な操作だけで様々な大きさや強度の改良材を得ることができるばかりでなく、これらの速度を調整するという簡単な操作だけで、小片化された粘性物の水分含有量や気候条件等に左右されることなく、安定した品質の改良土を得ることができて好ましい。   Furthermore, if the moving speed of the conveyor 1a and / or the rotational speed of the kneading and crushing blade driving means 2d can be adjusted, various size and strength improving materials can be obtained by a simple operation of adjusting these speeds. In addition to being able to adjust the speed, it is possible to obtain an improved soil of stable quality, without being affected by the moisture content of crushed viscous materials, climatic conditions, etc. Is preferable.

そして、解砕混練室1は前記コンベア1aと、コンベア1aの上流側の端縁近傍から下流側の端縁近傍にまで亘ってコンベア1aの長手方向の両端縁近傍より略鉛直に立設されている一対の側壁1c,1cと、両側壁1c,1cの上流側の側縁間に立設されている上流壁1dと、両側壁1c,1cの上縁と上流壁1dの上縁とにその端縁を連結されてコンベア1aの上方を覆っておりその上流側には小片化された粘性物をコンベア1a上面に投入するための投入口1eaが開口した天井材1eとで区画されており、これらの解砕混練室1を区画する部材によって、混練解砕手段1bにより押し飛ばされる粘性物は解砕混練室1内から外部へ飛散してまうことが防止されると共に、解砕混練室1内を後述する改良材供給噴霧手段2により霧状に噴霧された改良材が浮遊した雰囲気に保つ役目を果たす。   The crushing and kneading chamber 1 is erected substantially vertically from the vicinity of both ends of the conveyor 1a in the longitudinal direction from the vicinity of the upstream edge of the conveyor 1a to the vicinity of the downstream edge. A pair of side walls 1c, 1c, an upstream wall 1d standing between the upstream side edges of both side walls 1c, 1c, an upper edge of both side walls 1c, 1c and an upper edge of the upstream wall 1d The edge is connected and covers the upper part of the conveyor 1a, and on the upstream side thereof is divided with a ceiling material 1e having an opening 1ea for introducing a fragmented viscous material into the upper surface of the conveyor 1a, By the members partitioning the crushing and kneading chamber 1, the viscous material pushed away by the kneading and crushing means 1b is prevented from being scattered from the inside of the crushing and kneading chamber 1 to the outside. The role of maintaining the atmosphere in which the improved material sprayed in a mist form by the improved material supply spraying means 2 to be described later is suspended. Plus.

この解砕混練室1の一対の側壁1c,1c,上流壁1d及び天井材1eとしては、鋼板や合成樹脂製の板等の材料を用いることが可能であるが、解砕混練室1の一対の側壁1c,1c,上流壁1d及び天井材1eの内面が、水分を含有する汚泥等より構成される小片化された粘性物との摩擦が小さい低摩擦材料、例えばテフロン(商品名:デュポン社製)の如き弗化エチレン樹脂,超高分子量ポリエチレン(例えば、ソマール社製商品名:ソマライト,作新工業社製商品名:ニューライト),MCナイロン,ナイロン6,ナイロン66,ポリアセタール,PVC,鏡面仕上げステンレス鋼板等で形成されていれば、その内面へ跳ね上げられた粘性物が付着するのを最小限に防止することができるばかりでなく、付着した粘性物が堆積してその重さが増加することによりコンベア1a上に落下して解砕混練処理の不完全な状態の改良土が排出されてしまう現象を防止することができて好ましい。   As the pair of side walls 1c, 1c, upstream wall 1d and ceiling material 1e of the crushing and kneading chamber 1, materials such as steel plates and synthetic resin plates can be used. Side walls 1c, 1c, upstream wall 1d, and ceiling material 1e have a low friction material such as Teflon (trade name: DuPont) whose inner surface is made of sludge containing moisture and that has a small friction with small pieces of viscous material. Fluorine ethylene resin, ultra high molecular weight polyethylene (for example, Somalite, trade name: Somalite, Sakushin Kogyo, trade name: Newlite), MC nylon, nylon 6, nylon 66, polyacetal, PVC, mirror surface If it is made of a finished stainless steel plate, etc., it can not only prevent the viscous material splashed on its inner surface from adhering to the minimum, but also the adhered viscous material accumulates and its weight increases. By doing This is preferable because it can prevent the phenomenon that the improved soil in an incomplete state of the pulverization and kneading process is discharged on the conveyor 1a.

また、この解砕混練室1の天井材1eは、図2に示す如く解砕混練室1の天井材1eの一部又は全部が、幅方向が上方に円弧を成すように着脱自在に設置されている可撓性シートで構成されているので、その内面へ跳ね上げられた粘性物はその円弧の法線方向より衝突することが殆どないから、粘性物の跳ね上げられた力は分散してその内面に粘性物が付着するのを最小限に防止することができるばかりでなく、仮に天井材1eに粘性物が付着してしまったとしても、可撓性シートの外面側より手等で打撃を加えることにより、可撓性シートを取り外すことなく簡単に可撓性シートに付着した粘性物を落下させることができると共に、可撓性シートは着脱自在に設置されているので、可撓性シートを取り外すことにより解砕混練室1内の混練解砕手段1bやコンベア1a等の保守・点検等が簡単にできるので好ましい。 Further , as shown in FIG. 2 , the ceiling material 1e of the crushing and kneading chamber 1 is detachably installed so that a part or all of the ceiling material 1e of the crushing and kneading chamber 1 forms an arc upward in the width direction. consists of a flexible sheet which Runode, viscous substance thrown up to the inner surface because there is little collide from the normal direction of the arc, splashed force viscous material is dispersed Not only can the sticking of the sticky material to the inner surface be minimized, but even if the sticky material sticks to the ceiling material 1e, it is struck by hand from the outer surface side of the flexible sheet. By adding, the viscous material attached to the flexible sheet can be easily dropped without removing the flexible sheet, and the flexible sheet is detachably installed. Kneading and crushing means 1 in the crushing and kneading chamber 1 by removing the It is preferable because maintenance and inspection of the b and the conveyor 1a can be easily performed.

更に、この解砕混練室1の天井材1eを間欠的に打撃して天井材1eの内面に付着した粘性物をコンベア1a上に落下させるための打撃装置、例えば図示しないがエアシリンダ等のロットの先端に打撃部が装着されており、このエアシリンダ等を間欠的に作動させることにより打撃部で間欠的に天井材1eの外面を打撃するような装置が設けられていれば、天井材1eに付着してしまった粘性物を解砕混練室1から天井材1eを取り外したり手等で打撃を加えることなく自動的に除去できるので好ましい。   Further, a striking device for intermittently striking the ceiling material 1e of the crushing and kneading chamber 1 and dropping the viscous material adhering to the inner surface of the ceiling material 1e onto the conveyor 1a, for example, a lot such as an air cylinder (not shown) If a striking part is attached to the tip of the ceiling member 1e, and a device that strikes the outer surface of the ceiling material 1e intermittently at the striking part by operating this air cylinder or the like intermittently, the ceiling material 1e It is preferable because the viscous material adhering to the surface can be automatically removed without removing the ceiling material 1e from the crushing and kneading chamber 1 or hitting it manually.

2は解砕混練室1内の投入口1ea近傍へ改良材を供給するスクリューフィーダ2aと、円筒状を成し投入口1eaより投入される小片化された粘性物に向けて開口した噴霧口2baが側面に形成されスクリューフィーダ2aの吐出口2aaの下方に設けられている噴霧筒2bと、この噴霧筒2bの下方に噴霧筒2bと僅かに隙間を空けて設置され上面に複数の凸条部2caが設けられている円盤2cと、この円盤2cを高速回転させる円盤駆動手段2dとから成り、円盤2cの回転力によって改良材を噴霧筒2bの噴霧口2baより解砕混練室1内に霧状に拡散させる改良材供給噴霧手段であり、解砕混練室1の投入口1eaよりコンベア1a上の上流側に投入される小片化された粘性物の表面に全体的に改良材を付着させると共に、解砕混練室1内を霧状に噴霧された改良材が浮遊した雰囲気にさせる役目を果たす。   2 is a screw feeder 2a for supplying an improved material to the vicinity of the inlet 1ea in the crushing and kneading chamber 1, and a spray outlet 2ba which is formed in a cylindrical shape and opens toward a fragmented viscous material which is supplied from the inlet 1ea. Is formed on the side surface and provided below the discharge port 2aa of the screw feeder 2a, and a plurality of ridges on the upper surface are installed below the spray cylinder 2b with a slight gap between the spray cylinder 2b. It consists of a disk 2c provided with 2ca and disk drive means 2d for rotating the disk 2c at high speed. The improved material is sprayed into the crushing and kneading chamber 1 from the spray port 2ba of the spray cylinder 2b by the rotational force of the disk 2c. It is an improved material supply spraying means for diffusing in the form of a material, and adheres the improved material as a whole to the surface of the fragmented viscous material introduced upstream from the inlet 1ea of the crushing kneading chamber 1 on the conveyor 1a. The atmosphere in which the improved material sprayed in the form of a mist floats in the crushing and kneading chamber 1 is floated. Play a role.

改良材供給噴霧手段2のスクリューフィーダ2aは、解砕混練室1外に別途設けられた改良材が収容されているサイロ等の吐出口と解砕混練室1内の投入口1ea近傍との間に解砕混練室1の側壁1c,上流壁1d又は天井材1eを貫通するように設置されており、改良材をスクリューフィーダ2aの吐出口2aaより吐出させることにより解砕混練室1内の投入口1ea近傍へ改良材を供給する。   The screw feeder 2a of the improved material supply / spraying means 2 is provided between a discharge port such as a silo in which an improved material separately provided outside the crushing and kneading chamber 1 is accommodated and the vicinity of the inlet 1ea in the crushing and kneading chamber 1. Is installed so as to pass through the side wall 1c, upstream wall 1d or ceiling material 1e of the crushing and kneading chamber 1, and the improved material is discharged from the discharge port 2aa of the screw feeder 2a into the crushing and kneading chamber 1. Supply improvement material near the mouth 1ea.

改良材供給噴霧手段2の噴霧筒2bは、図3に示す如く円筒状を成しスクリューフィーダ2aの吐出口2aaの下方に設けられていると共に、この噴霧筒2bの側面には投入口1eaより投入される小片化された粘性物に向けて開口した噴霧口2baが形成されており、スクリューフィーダ2aの吐出口2aaより供給される改良材を高速回転する円盤2cへと導くと共に、円盤2cの回転力により円盤2cの中心より法線方向へと飛ばされる改良材をその側面に開口した噴霧口2baへ導いて、その噴霧口2baから霧状に噴霧させるのである。   As shown in FIG. 3, the spray cylinder 2b of the improved material supply spray means 2 has a cylindrical shape and is provided below the discharge port 2aa of the screw feeder 2a. A spray port 2ba that opens toward the fragmented viscous material to be charged is formed, and the improved material supplied from the discharge port 2aa of the screw feeder 2a is guided to the disk 2c that rotates at a high speed, and the disk 2c The improved material, which is blown in the normal direction from the center of the disk 2c by the rotational force, is guided to the spray port 2ba opened on the side surface, and sprayed in a mist form from the spray port 2ba.

改良材供給噴霧手段2の円盤2cは、図3に示す如く噴霧筒2bの下方に噴霧筒2bと僅かに隙間を空けて設置され上面に複数の凸条部2caが設けられており、噴霧筒2bにより導かれた改良材をこの高速回転する円盤2cの上面に設けられた複数の凸条部2caによって円盤2cの中心より法線方向へと飛ばすと共に多少塊状になっている改良材を崩して粉末状にするのである。   As shown in FIG. 3, the disk 2c of the improved material supply spraying means 2 is installed below the spray cylinder 2b with a slight gap from the spray cylinder 2b and provided with a plurality of convex strips 2ca on the upper surface. The improvement material led by 2b is blown away from the center of the disk 2c in the normal direction by the plurality of convex strips 2ca provided on the upper surface of the disk 2c rotating at high speed, and the improvement material that is somewhat agglomerated is destroyed. It is powdered.

ここで、この円盤2cが噴霧筒2bの下方に噴霧筒2bと僅かに隙間を空けて設置されているのは、仮に円盤2cを噴霧筒2b内に設置した場合には、噴霧筒2bの内面と円盤2c外周面との間に改良材が入り込んで固化してしまったり、噴霧筒2bの内面と円盤2c外周面との間から入り込んだ改良材が円盤2cを回転駆動させる円盤駆動手段2dの回転軸やそのベアリング等に付着して固化してしまったりして、円盤2cの回転の抵抗となってしまうばかりでなく、円盤駆動手段2dに過大な負荷をかけて故障の原因となってしまう恐れがあるので、円盤2cが噴霧筒2bの下方に噴霧筒2bと僅かに隙間を空けて設置されていることにより、噴霧筒2bの下縁と円盤2cの上面との間に入り込んでしまった改良材は、円盤2cの回転力によってその僅かな隙間より解砕混練室1へと飛ばされるので、円盤2cの回転の抵抗や円盤駆動手段2dの故障の原因を排除できるからである。   Here, the disk 2c is installed below the spray cylinder 2b with a slight gap from the spray cylinder 2b. If the disk 2c is installed in the spray cylinder 2b, the inner surface of the spray cylinder 2b Of the disk drive means 2d for rotating the disk 2c by the improved material entering between the inner surface of the spray cylinder 2b and the outer surface of the disk 2c. Not only will it stick to the rotating shaft and its bearings and solidify, it will become resistance to rotation of the disk 2c, but it will also cause an overload on the disk drive means 2d and cause failure Because there is a fear, the disk 2c is installed below the spray cylinder 2b with a slight gap from the spray cylinder 2b, so that it has entered between the lower edge of the spray cylinder 2b and the upper surface of the disk 2c. The improved material is blown to the crushing and kneading chamber 1 through the slight gap by the rotational force of the disk 2c. Since, because it eliminates the cause of the failure of the resistance or the disc drive unit 2d of the rotation of the disk 2c.

そして、この円盤2cとしては、その上面に複数の凸条部2caが設けられているものであれば何でもよいが、図4に示す如くその中心より放射方向に複数設けられていれば、より確実且つ広範囲に改良材を解砕混練室1内に霧状に拡散させることができるので、小片化された粘性物と改良材との混合状態が向上して好ましい。   The disk 2c may be anything as long as it has a plurality of ridges 2ca on its upper surface, but it is more reliable if a plurality of disks 2c are provided radially from the center as shown in FIG. In addition, since the improving material can be diffused in the pulverizing and kneading chamber 1 in a wide range in a wide range, the mixed state of the fragmented viscous material and the improving material is preferably improved.

改良材供給噴霧手段2の円盤駆動手段2dとしては、例えばモータ等の回転軸を円盤2cの中心に穿設された穴に直接嵌入しモータ等を回転駆動させることにより円盤2cを高速回転できるように構成されていてもよいが、図1及び図3に示す如く解砕混練室1外に設置されその回転軸にプーリが嵌着されたモータと、その上方が円盤2cの中心に穿設された穴に嵌入されその中間に設けられたベアリングを介して軸支されその下方にプーリが嵌着された円盤回転軸と、両プーリに掛け渡されるベルトと、これらが収納される筐体とで円盤駆動手段2dを構成すれば、円盤駆動手段2dは改良材が浮遊する解砕混練室1内の雰囲気に直接曝されるれることがないから、円盤駆動手段2dの寿命を伸ばすことができるので好ましい。   As the disk drive means 2d of the improvement material supply spray means 2, the disk 2c can be rotated at a high speed by, for example, inserting a rotation shaft of a motor or the like directly into a hole formed in the center of the disk 2c and driving the motor or the like to rotate. As shown in FIGS. 1 and 3, the motor is installed outside the crushing and kneading chamber 1 and a pulley is fitted on the rotating shaft thereof, and the upper part is drilled in the center of the disk 2c. A disc rotating shaft that is pivotally supported through a bearing provided in the middle of the hole and has a pulley fitted below it, a belt that spans both pulleys, and a housing that houses these. If the disk drive means 2d is configured, the disk drive means 2d is not directly exposed to the atmosphere in the crushing and kneading chamber 1 where the improved material floats, so the life of the disk drive means 2d can be extended. preferable.

このように構成されている改良材供給噴霧手段2は、その噴霧筒2bに開口した噴霧口2baが投入口1eaより投入される小片化された粘性物に向くようにしてそのスクリューフィーダ2aを解砕混練室1の側壁1c又は天井材1eを貫通するように設置すればよいが、図1又は図3に示す如くそのスクリューフィーダ2aが上流壁1dを貫通するように設置されることにより、改良材供給噴霧手段2を解砕混練室1内の投入口1ea近傍であってコンベア1aによる移送方向の最も上流側に設ければ、改良材供給噴霧手段2の噴霧筒2bの噴霧口2baより噴霧される改良材が解砕混練室1の下流側の方まで更に霧状に拡散され易いから、解砕混練室1内がコンベア1a上に移送されてくる粘性物や複数の混練解砕刃1bbにより上流側へ押し飛ばされる粘性物に改良材が再付着し易い雰囲気となるので、小片化された粘性物と改良材との混合が向上して好ましい。   The improved material supply spraying means 2 configured in this way disassembles the screw feeder 2a so that the spraying port 2ba opened in the spraying cylinder 2b faces the fragmented viscous material charged from the charging port 1ea. It may be installed so as to penetrate the side wall 1c or the ceiling material 1e of the crushing and kneading chamber 1, but it is improved by installing the screw feeder 2a so as to penetrate the upstream wall 1d as shown in FIG. 1 or FIG. If the material supply spraying means 2 is provided in the vicinity of the inlet 1ea in the crushing and kneading chamber 1 and at the most upstream side in the transfer direction by the conveyor 1a, the spray is supplied from the spraying port 2ba of the spray cylinder 2b of the improved material supply spraying means 2. Since the improved material is more easily diffused in the form of a mist toward the downstream side of the crushing and kneading chamber 1, viscous materials and a plurality of kneading and crushing blades 1bb are transferred to the conveyor 1 a in the crushing and kneading chamber 1. The improved material tends to re-adhere to the viscous material pushed away upstream by Since the 囲気, preferably with improved mixing of the modifying material and the small pieces are viscous product.

次に、このような構成の本発明に係る混練解砕装置の動作方法について説明する。
初めに準備として、水分を含有する汚泥等より構成される小片化された粘性物を用意すると共に改良材供給噴霧手段2のスクリューフィーダ2aに接続された解砕混練室1外に別途設けられているサイロ等に改良材を収容する。
Next, an operation method of the kneading and crushing apparatus according to the present invention having such a configuration will be described.
First, as a preparation, a small-sized viscous material composed of water-containing sludge and the like is prepared and separately provided outside the crushing and kneading chamber 1 connected to the screw feeder 2a of the improvement material supply spraying means 2. The improvement material is accommodated in a silo or the like.

この際、図示しないが別途設置された切出装置等により小片化された粘性物をバケットコンベアやフード付コンベア等のコンベアによって移送することにより解砕混練室1の天井材1eの上流側に開口した投入口1eaへ投入する態様の場合や、図1に示す如く切出装置Kが解砕混練室1の天井材1eの上流側に開口した投入口1ea上に設けられている態様の場合には、切出装置Kに水分を含有する汚泥等より構成される粘性物を供給する。   At this time, although not shown in the drawing, the viscous material fragmented by a cutting device or the like separately installed is transferred to the upstream side of the ceiling material 1e of the crushing and kneading chamber 1 by transferring it by a conveyor such as a bucket conveyor or a conveyor with a hood. In the case of the mode of charging into the charging port 1ea, or the mode in which the cutting device K is provided on the charging port 1ea opened upstream of the ceiling material 1e of the crushing and kneading chamber 1 as shown in FIG. Supplies the cutting device K with a viscous material composed of sludge containing moisture.

このような準備が完了した後に、改良材供給噴霧手段2のスクリューフィーダ2a,改良材供給噴霧手段2の円盤駆動手段2d,解砕混練室1のコンベア1a及び解砕混練室1の回転軸駆動手段1bcをそれぞれ起動させると共に、別途切出装置等やコンベア等が設置されている態様の場合や、切出装置Kが解砕混練室1の天井材1eの上流側に開口した投入口1ea上に設けられている態様の場合には、それぞれ起動させる操作を行う。   After such preparation is completed, the screw feeder 2a of the improved material supply spraying means 2, the disk drive means 2d of the improved material supply spraying means 2, the conveyor 1a of the crushing and kneading chamber 1, and the rotary shaft driving of the crushing and kneading chamber 1 are performed. Each of the means 1bc is activated and a cutting device or a conveyor is separately installed, or the cutting device K is on the inlet 1ea opened on the upstream side of the ceiling material 1e of the crushing and kneading chamber 1 In the case of the mode provided in the above, an operation for starting each is performed.

このような操作により、小片化された粘性物が解砕混練室1の天井材1eに開口した投入口1eaよりコンベア1a上の上流側に投入されるが、この際に改良材供給噴霧手段2は、スクリューフィーダ2aの吐出口2aaから改良材を吐出させ、吐出した改良材を円盤駆動手段2dにより高速回転させる円盤2cの回転力によって噴霧筒2bの噴霧口2baより小片化された粘性物に向けて噴霧すると共に解砕混練室1内に霧状に拡散させるので、投入口1eaより投入された小片化された粘性物はその表面に全体的に改良材が付着した状態でコンベア1a上の上流側に投入されると共に、解砕混練室1内は霧状に噴霧された改良材が浮遊した雰囲気となるのである。   By such an operation, the fragmented viscous material is introduced into the upstream side on the conveyor 1a from the introduction port 1ea opened in the ceiling material 1e of the crushing and kneading chamber 1. At this time, the improving material supply spray means 2 The discharge material 2a is discharged from the discharge port 2aa of the screw feeder 2a, and the improved material discharged is turned into a viscous material that is smaller than the spray port 2ba of the spray cylinder 2b by the rotational force of the disk 2c that rotates at high speed by the disk drive means 2d. Sprayed in the pulverization and kneading chamber 1 and sprayed into the crushing and kneading chamber 1 so that the fragmented viscous material introduced from the introduction port 1ea is on the conveyor 1a with the improved material attached to the entire surface. While being put into the upstream side, the pulverization kneading chamber 1 has an atmosphere in which the improved material sprayed in a mist form floats.

この小片化された粘性物はその表面に全体的に改良材が付着した状態でコンベア1a上の上流側に次々と投入されるから、投入される小片化された粘性物は複数積み重なった状態でコンベア1a上の上流側から下流側へと移送されるが、複数積み重なった状態の粘性物は個々にその表面に全体的に改良材が付着した状態で移送されるから、小片化された粘性物同士はその表面に全体的に付着した改良材を介して接触することになり、その際粘性物中からしみ出して来る水分により再び塊状になろうとするが、コンベア1aの上流側の中間近傍から下流側にかけて複数設けられた混練解砕手段1bまで移送されてくる間にも粘性物中の水分と改良材との反応が起こり粘性物中の水分量が減少して塊状になり難い状態になるのである。   Since this piece of viscous material is introduced one after another on the upstream side of the conveyor 1a with the improvement material attached to the entire surface, a plurality of pieces of the viscous material to be charged are stacked. Although it is transferred from the upstream side to the downstream side on the conveyor 1a, a plurality of stacked viscous materials are individually transferred with the improvement material attached to the entire surface thereof, so that the viscous material broken into small pieces They will come into contact with each other through the improvement material attached to the entire surface, and at that time, they try to become agglomerated again due to the moisture oozing out from the viscous material, but from the middle vicinity on the upstream side of the conveyor 1a. Even while being transferred to the kneading and crushing means 1b provided downstream, the reaction between the moisture in the viscous material and the improving material occurs and the amount of moisture in the viscous material decreases, making it difficult to form a lump. It is.

そして、複数積み重なった状態の粘性物は、それぞれの表面に全体的に改良材が付着した状態でコンベア1aの上方に上流側の中間近傍から下流側にかけて複数設けられた混練解砕手段1bの最も上流側に位置する混練解砕手段1bまで移送されてくると、混練解砕手段1bの回転軸駆動手段1bcによりコンベア1aによる移送方向と反対方向になるように回転される回転軸1baの側面より突設された複数の混練解砕刃1bbが移送されて来る粘性物の方向へ次々と回転してくることによって、粘性物は改良材と混練されると共に更に細かく解砕されるが、この解砕混練される粘性物の一部は、改良材供給噴霧手段2により霧状に噴霧された改良材が浮遊した雰囲気の解砕混練室1内を、コンベア1aによる移送方向と反対方向になるように回転される複数の混練解砕刃1bbによってコンベア1aの上流方向に向かって押し飛ばされるので、この押し飛ばされた粘性物の表面には再度改良材が付着し粘性物に対する改良材の混合状態が更に均一になるのである。   A plurality of the viscous materials in the stacked state are the most of the kneading and crushing means 1b provided above the conveyor 1a from the middle of the upstream side to the downstream side with the improvement material attached to the entire surface. When transferred to the kneading / disintegrating means 1b located on the upstream side, from the side surface of the rotating shaft 1ba that is rotated by the rotating shaft driving means 1bc of the kneading / disintegrating means 1b so as to be opposite to the transfer direction by the conveyor 1a. As the plurality of kneading and crushing blades 1bb provided in the projecting direction rotate one after another in the direction of the transferred viscous material, the viscous material is kneaded with the improving material and further crushed. Part of the viscous material to be crushed and kneaded is in a direction opposite to the transfer direction by the conveyor 1a in the crushing and kneading chamber 1 in the atmosphere in which the improved material sprayed in a mist form by the improved material supply spray means 2 floats. Multiple kneading and crushing Since skipped pushed toward the upstream direction of the conveyor 1a by 1bb, mixed state of the modifying material for viscous substance adhering again modifying material on the surface of the pressing skipped gum is becoming more uniform.

このようにコンベア1a上を移送されて来る粘性物は、コンベア1a上を上流側から下流側に向けて移送されている間やコンベア1aによる移送方向と反対方向になるように回転される複数の混練解砕刃1bbにより上流方向へ押し飛ばされている間において改良材と粘性物に含有されている水分とが反応する工程と、コンベア1aによる移送方向と反対方向になるように回転される複数の混練解砕刃1bbにより改良材との混練される共に更に細かく解砕される工程と、改良材供給噴霧手段2により霧状に噴霧された改良材が浮遊した雰囲気の解砕混練室1内においてコンベア1a上を移送している間やコンベア1aによる移送方向と反対方向になるように回転される複数の混練解砕刃1bbにより押し飛ばされている最中に改良材が再付着するという工程とを何度も繰り返して、最終的にコンベア1aの下流側より粒状になった改良土として排出されるのである。   As described above, the viscous material transferred on the conveyor 1a is rotated while being transferred from the upstream side toward the downstream side on the conveyor 1a or in a direction opposite to the transfer direction by the conveyor 1a. A process in which the improved material reacts with moisture contained in the viscous material while being pushed away in the upstream direction by the kneading and crushing blade 1bb, and a plurality of rotations so as to be opposite to the transfer direction by the conveyor 1a In the pulverization and kneading chamber 1 in which the improvement material sprayed in the form of mist by the improvement material supply spray means 2 floats and is further kneaded with the improvement material by the kneading and crushing blade 1bb. The improvement material is reattached while being transported on the conveyor 1a or while being pushed away by a plurality of kneading and crushing blades 1bb rotated in the direction opposite to the direction of transport by the conveyor 1a. And repeatedly Returns, than it is discharged as the final modified soil became granular downstream side of the conveyor 1a.

そして、本発明装置はこのような工程を繰り返して行うことができるものであるから、最小限の改良材によって改良材が均一に混合されその反応状態が均一な所望の大きさや形状の粒状になった良好な改良土を得ることができるので、改良材を無駄にすることがないと共に粘性物を粒状になった品質が一定で良好な改良土へと処理する効率を飛躍的に向上させることができ、また混練解砕刃1bbの数や形状等,回転軸等の数や位置等や,コンベア1aの長さ等を適宜変更することにより、様々な用途に使用することができる様々な大きさ、形状や強度の良質な改良土を得ることができるのである。   Since the apparatus of the present invention can perform such a process repeatedly, the improved material is uniformly mixed with the minimum improved material, and the reaction state becomes a uniform particle having a desired size and shape. Therefore, it is possible to obtain a highly improved soil so that the improvement material is not wasted and the efficiency of processing the viscous material into a good improved soil with a constant quality of granulated material can be dramatically improved. Various sizes can be used for various purposes by appropriately changing the number and shape of the kneading and crushing blades 1bb, the number and position of the rotating shafts, the length of the conveyor 1a, etc. It is possible to obtain improved soil with good shape and strength.
