Description

本発明は例えば、下水処理場、し尿処理場、畜産農業、食料品製造業、化学工業などの汚泥を含む排水の処理施設において発生する、液体中に含まれている汚泥の固形物、特に懸濁固形物（ＳＳ）を分離した固分と液分を各別に取り出すための装置に関するものである。 The present invention includes, for example, sludge solids contained in liquids, particularly suspensions generated in wastewater treatment facilities including sludge such as sewage treatment plants, human waste treatment plants, livestock agriculture, food manufacturing industries, and chemical industries. The present invention relates to an apparatus for separately taking out a solid content and a liquid content from which a turbid solid (SS) is separated.

現在、下水処理場、し尿処理場、畜産農業、食料品製造業、化学工業などの排水の処理場において発生する汚泥を含む排水即ち懸濁汚水は環境破壊の問題から、そのままでは排水することが出来ないことは周知のことであり、懸濁汚水に含まれる懸濁固形物（ＳＳ）を可能な限り除去した状態で処理することが課題となっている。 Currently, wastewater containing sludge generated in wastewater treatment plants such as sewage treatment plants, human waste treatment plants, livestock farming, food manufacturing industries, and chemical industries, ie suspended sewage, can be drained as it is due to environmental damage. What cannot be done is a well-known thing, and it has become a subject to process in the state which removed the suspended solid (SS) contained in suspended sewage as much as possible.

そのために、大と小および間隙保持用の直径の異なる各濾片を一組として、それら複数組を回転軸に挿嵌固定された積層濾体を排出方向へ向かって等間隔に複数配列させて、該積層濾体を同一方向に回転させて、相隣接する積層濾体の一方における送り濾片の外周縁が他方の積層濾体における間隙濾片の外周縁に接近した態様とし、この積層濾体の、送り濾片は前後に隣接する間隙濾片と向き合うように組み合わされており、各積層濾体の回転により、送り濾片は間隙濾片の細い隙間に食い込む形で回転することにより、濾過面の目詰りを防止している懸濁液を濾過する装置は公知である（例えば、特許文献１参照）。 For this purpose, a set of large and small filter pieces with different diameters for holding gaps is used as a set, and a plurality of stacked filter bodies in which the plurality of sets are inserted and fixed to the rotation shaft are arranged at equal intervals in the discharge direction. The laminated filter body is rotated in the same direction so that the outer peripheral edge of the feed filter piece in one of the adjacent laminated filter bodies approaches the outer peripheral edge of the gap filter piece in the other laminated filter body. The feed filter piece of the body is combined so as to face the front and rear adjacent gap filter pieces, and by rotating each laminated filter body, the feed filter piece rotates in a form that bites into the narrow gap of the gap filter piece, An apparatus for filtering a suspension that prevents clogging of the filtration surface is known (for example, see Patent Document 1).

また、別に背景技術として、ボルトとナットを用いてスペーサを取付けた固定リングを複数枚積層させて液体ガイド溝を構成し、その内周に遊動リングを配置し、スクリューコンベアを駆動させて遊動リングを偏心回転させることで汚泥水を固形分と水分に分離を行う装置も公知である（例えば、特許文献２参照）。 In addition, as another background art, a plurality of fixing rings with spacers attached using bolts and nuts are stacked to form a liquid guide groove, an idle ring is arranged on the inner periphery, and the screw conveyor is driven to idle ring. An apparatus that separates sludge water into solid content and moisture by rotating the shaft eccentrically is also known (see, for example, Patent Document 2).

しかしながら、前記特許文献１の懸濁液を濾過する装置においては、小径円板状濾片の細い隙間は食い込む形で回転する大径円板状濾片の厚さより僅かでも広くならなければならないが、大径円板状濾片が回転軸に完全固定されており同一軌道を回転するため、本来掻きださなければならない濾過脱水物のケーキが細い隙間で大径円板状濾片の厚みを除く領域が付着固形化し、濾過面の目詰りが発生することで懸濁液の固液分離ができなくなり、また、大・小径円板状濾片は０．２ｍｍ〜１ｍｍ程度の極く薄いものであるので、そのプレス加工やレーザー加工の際に加工歪や熱歪が生じるため、歪取りが必要であり、円板状濾片の径を大きくすると、歪の影響が顕著となり相隣接する小径円板状濾片の細かい隙間を構成する大径円板状濾片の両側面が接触干渉されて、積層濾体の回転軸トルクが増大することに加えて、大・小円板状濾片の摩耗が早まることとなり、更に、大径および小径円板状濾片を積層固定することで濾過溝を形成していることから、濾過溝の幅と位置の精度は両濾片の厚みと平坦度の精度および積層組立時の締付加減等に大きく影響されるので、組立時には細心の注意と調整が必要とされることから、組立には多くの労力と熟練が必要とされるという欠点があった。 However, in the apparatus for filtering the suspension of Patent Document 1, the narrow gaps of the small-diameter disk-shaped filter pieces must be slightly larger than the thickness of the large-diameter disk-shaped filter pieces that rotate in a biting manner. Since the large-diameter disc-shaped filter piece is completely fixed to the rotating shaft and rotates on the same track, the cake of the filtered dehydrated product that has to be scraped off naturally increases the thickness of the large-diameter disc-shaped filter piece through a narrow gap. The area to be removed is solidified and the filtration surface becomes clogged, making it impossible to separate the suspension from solid and liquid. Large and small-diameter disk-shaped filter pieces are extremely thin, about 0.2 mm to 1 mm. Therefore, since processing strain and thermal strain occur during the press processing and laser processing, it is necessary to remove the strain, and when the diameter of the disk-shaped filter piece is increased, the effect of strain becomes significant and the adjacent small diameter Of large-diameter disk-shaped filter pieces that form fine gaps in disk-shaped filter pieces In addition to increasing the rotating shaft torque of the laminated filter body due to contact interference on the side surfaces, wear of large and small disk-shaped filter pieces is accelerated, and large-diameter and small-diameter disk-shaped filter pieces are laminated. Since the filtration groove is formed by fixing, the accuracy of the width and position of the filtration groove is greatly affected by the thickness and flatness accuracy of both filter pieces and the reduction of tightening during stacking assembly. Since careful attention and adjustment are sometimes required, assembly has the drawback of requiring a lot of labor and skill.

また、特許文献２記載の固液分離装置においては、スクリューコンベアが汚泥水を流入口から排出口まで押し出すように分離を行う構成であるため、汚泥水の流入口側のスペーサが磨耗しやすく、都度部品交換を要するという欠点があった。 Further, in the solid-liquid separation device described in Patent Document 2, since the screw conveyor is configured to separate the sludge water so as to push the sludge water from the inlet to the outlet, the spacer on the inlet side of the sludge water is likely to wear, There was a drawback that parts had to be replaced each time.

そこで、本発明は前記問題点を鑑み、樹脂成型時に濾片に生じる歪みを抑制し、各濾片の組み立てを容易にすることが可能な固液分離装置を提供することを目的とする。 In view of the above problems, an object of the present invention is to provide a solid-liquid separation device that can suppress distortion generated in a filter piece during resin molding and facilitate the assembly of each filter piece.

本発明の請求項１または２のいずれか一項に記載の固液分離装置において、本発明の請求項６に係る発明は、前記積層濾体の始端開口部を懸濁汚水の原液供給口とし、終端開口部を固分排出口として、スクリューブレードの外径が濾過プレートの内径よりも大きく凸子濾片または濾片の内径より小さく形成されたスクリューコンベアを前記積層濾体の中心孔に嵌装するように構成されている。 In the solid-liquid separator according to any one of claims 1 and 2, the invention according to claim 6 of the present invention is characterized in that the starting end opening of the laminated filter body is a stock solution supply port of suspended sewage. A screw conveyor having a terminal opening as a solid outlet and an outer diameter of the screw blade larger than an inner diameter of the filter plate and smaller than an inner diameter of the filter piece is fitted into the center hole of the laminated filter body. It is configured to wear.

本発明の請求項１の発明に係る固液分離装置によれば、固液分離装置において、各濾片間を所要間隔の濾過溝に保持するための間隔保持具を該濾片の表裏面に凸子として一体的に樹脂成型することで、濾片の金型を調整するのみで精度よく積層可能な濾片を構成することが可能となる。 According to the solid-liquid separation device of the first aspect of the present invention, in the solid-liquid separation device, the interval holders for holding the gaps between the filter pieces in the filtration grooves having the required intervals are provided on the front and back surfaces of the filter pieces. by integrally resin-molded as Totsuko, that Do is possible to form accurately stackable濾片only adjusting the mold濾片.

また、本発明の請求項１に基づいた請求項２の発明に係る固液分離装置によれば、前記濾片の表裏面の三箇所以上に凸子を一体的に樹脂成型した濾片を凸子濾片として構成されているので、多数枚の濾片を安定して積層可能となるとともに、凸子を形成することで、他方の凸子濾片との当接面積を小さくすることが可能となり、樹脂成型時における冷却時間の差異によって凸子濾片の各部位が収縮することにより生じる歪みを凸子で吸収し、管理する事ができるので、凸子を形成することで濾片全体の歪みを抑制する事が可能となり、さらに、凸子濾片の凸子端面の凸設高さが表裏両面とも同一に構成されているならば、凸子の高さが均一化されることで樹脂成型時における冷却時間が凸子の表裏両面とも同じとなり、冷却時に濾片が収縮することにより生じる応力により表面側の凸子が曲がろうとするが、同様に裏面側の凸子も曲がろうとするので、凸子の表面、裏面で互いに曲がりが相殺され、濾片に生じる歪みをより抑制する事が可能となり、かつ組み立て時において、凸子濾片の表面、裏面の向きに関係無く回転軸へ挿嵌することが可能となり、例えば固液分離装置を駆動させる事で凸子濾片の表面側の凸子が磨耗したとしても、凸子濾片を裏返して裏面の凸子を利用する事が可能となる効果を有している。 Further, according to the solid-liquid separation device according to the second aspect of the present invention based on the first aspect of the present invention, the filter pieces formed by integrally resin-molding the protrusions on the front and back surfaces of the filter pieces are convex.

The cooling time at the time of molding is the same on both the front and back sides of the convex, and the filter piece shrinks during cooling The convex on the front side tends to bend due to the stress caused by the stress, but the convex on the back side also tends to bend. It is possible to further suppress and at the time of assembly, it is possible to insert into the rotating shaft regardless of the direction of the front and back surfaces of the convex filter piece, for example, by driving the solid-liquid separation device Even if the protrusion on the front surface side of the piece is worn, it has an effect that it is possible to turn the protrusion filter piece over and use the protrusion on the back surface.

さらに、本発明の請求項２に基づいた請求項３の発明に係る固液分離装置によれば、凸子濾片の凸子端面を環状に凸設するよう、表裏両面または一方の面の凸子端面の中央部に窪みが形成されているので、凸子の当接面積が小さくなり、樹脂成型時において窪みの内側と外側を均等に冷却されるので、凸子部分も含め凸子濾片全体の冷却時間が均一化され、凸子濾片の各部位の冷却時間の差異によって生じる歪みの発生をより効果的に防止することが可能となる効果を有している。 Furthermore, according to the solid-liquid separation device according to the third aspect of the present invention based on the second aspect of the present invention, both the front and back surfaces or one of the convex surfaces is provided so as to project the convex end surface of the convex filter piece in an annular shape. Since the depression is formed in the center of the end face, the contact area of the protrusion is reduced, and the inside and outside of the depression are cooled evenly during resin molding. The entire cooling time is made uniform, and it is possible to more effectively prevent the occurrence of distortion caused by the difference in cooling time of each part of the convex filter piece.

A plurality of laminated filter bodies, which are stacked in a stacking order in which the outer edges of the opposing filter plates do not interfere with each other due to the stacking order configuration of the filter bodies, receive suspended sewage and separate the solids and liquids while filtering them. Provided at the center of each laminated filter body to be transferred to the discharge port Since it is configured to efficiently separate and filter by the laminated filter bodies that are adjacently arranged in two separate stages while being driven and rotated by the rotating shaft, the solid-liquid separation device for the convex filter pieces is driven. Even if it is necessary to replace the convex filter piece, if the height of the convex element formed on the convex filter piece is the same on both the front and back surfaces, the convex part will be The subfilter piece can be easily replaced, and the workability can be improved.

本発明の請求項４に基づいた請求項５の発明に係る固液分離装置によれば、凸子濾片と大径濾過プレートには濾液孔および小径濾過プレートには濾液切欠孔をそれぞれ同心状に穿設し、該濾液孔および濾液切欠孔は積層後の上記両積層濾体内に濾液路を形成し、該濾液路の送液終端開口部は前記固液分離装置側壁の外側に付設された濾液室内に導通され、該濾液室下壁に濾液室排水口を開設するように構成されているので、濾液路のない積層濾体の場合よりも、濾液路経由の濾液室下壁の濾液室排水口からの排水が加わることから、濾過溝内で揺動回転する大径および小径濾過プレートの濾液分離能力が向上されることで、濾液分離機能の向上と含水率の低い濾過脱水物のケーキが回収し得るという効果を有している。 According to the solid-liquid separator according to the invention of claim 5 based on claim 4 of the present invention, the convex filter pieces and the large-diameter filtration plate have concentric filtrate holes, and the small-diameter filter plate has concentric filtrate notches. The filtrate hole and the filtrate notch hole form a filtrate path in the two laminated filter bodies after lamination, and a liquid feed terminal opening of the filtrate path is provided outside the side wall of the solid-liquid separator. Since it is connected to the filtrate chamber and is configured to open a filtrate chamber drain on the lower wall of the filtrate chamber, the filtrate chamber on the lower wall of the filtrate chamber via the filtrate path is more than in the case of a laminated filter body without a filtrate path. Since drainage from the drainage port is added, the filtrate separation capacity of the large and small diameter filtration plates that swing and rotate in the filtration groove is improved. Has the effect that can be recovered.

As the solid content outlet, a screw conveyor formed so that the outer diameter of the screw blade is larger than the inner diameter of the filter plate and smaller than the inner diameter of the convex filter piece is fitted into the center hole of the laminated filter body. Therefore, suspended sewage is pushed out from the opening at the start end to the end opening, and the protrusion on the start end opening side is very easily worn, but the height of the protrusion formed on the protrusion filter piece is convex. If the front and back surfaces of the sub filter piece are configured identically, the convex filter piece can be mounted upside down and used.
