Used paper diapers, sterilized paper pads, sanitary products, etc. (used paper hygiene products: hereinafter referred to as used paper diapers) are currently incinerated, but used paper diapers are human waste Therefore, if the combustion temperature is not increased, combustion cannot be completed, and the processing cost is increased.
 このような状況下で、使用済み紙おむつ等を処理することで燃料等として利用するための種々の方法が提案されている。使用済み紙おむつ等を処理する方法としては、例えば、水溶分離法、高温蒸気による炭化処理法、植物性油加熱加工処理法及び発酵菌を用いた発酵処理法などが挙げられる。 Under such circumstances, various methods have been proposed for use as fuel etc. by processing used paper diapers and the like. Examples of a method for treating used paper diapers include a water separation method, a carbonization method using high-temperature steam, a vegetable oil heat processing method, and a fermentation method using fermenting bacteria.
 高温蒸気による炭化処理法として、廃棄物を攪拌しながら無酸素状態で高温蒸気に曝して炭化させる技術が従来から提案されている(例えば、特許文献1参照)。植物性油加熱熱加工法として、使用済み紙おむつを破砕することなく、植物性油あるいは鉱物性油の廃油で加熱処理して燃料化する技術が従来から提案されている(例えば、特許文献2参照)。 As a carbonization treatment method using high-temperature steam, there has been conventionally proposed a technique in which waste is carbonized by exposure to high-temperature steam in an oxygen-free state while stirring (for example, see Patent Document 1). As a vegetable oil heating heat processing method, a technique for heat treatment with waste oil of vegetable oil or mineral oil without crushing used paper diapers has been proposed (see, for example, Patent Document 2). ).
 しかし、従来から提案されている使用済み紙おむつ等を炭化させる装置では、高温蒸気作成のためのボイラー及び成果物冷却用のクーリング機構等の高額設備が必要になり、高コストになってしまうという問題があった。 However, the conventionally proposed apparatus for carbonizing used disposable diapers, etc., requires expensive equipment such as a boiler for producing high-temperature steam and a cooling mechanism for cooling product, resulting in high costs. was there.
 また、廃油で加熱処理する技術では、植物性油等による糞尿の熱加工及びプラスチック等の樹脂を更に油を加熱し溶解するため、設備が大型化してしまうと共に油等の加熱コストがかかってしまうという問題があった。また、植物性油熱加工法の乾燥工程では、高熱溶解液状化工程後、冷却し、液状油成分と固形成分とゲル状成分をろ過分別しているが、これも設備が大型化してしまうという問題があった。 In addition, in the technology of heat treatment with waste oil, heat processing of manure with vegetable oil and resin such as plastic are further heated to dissolve the oil, resulting in an increase in equipment size and heating costs for oil and the like. There was a problem. Moreover, in the drying process of the vegetable oil heat processing method, after the high-heat dissolution liquefaction process, the liquid oil component, the solid component, and the gel component are separated by filtration, but this also increases the size of the equipment. was there.

The used paper hygiene product is crushed and cut to produce a crushed product that is subdivided into a desired size. Since the first rotary blade 31 and the second rotary blade 41 are in a spiral direction in which they are reversely threaded, the crushed material is moved to the center side of the rotary shaft 25 (the discharge port 5 side) by driving rotation on one side of the rotary shaft 25. ), And the crushed material is diffused to both ends of the rotating shaft 25 by driving rotation on the other side of the rotating shaft 25.
 上述したように、破砕手段21は、回転軸25の駆動回転により使用済み紙衛生用品を攪拌しながら破砕及び裁断することができる。そして、回転軸25の一方向の回転により破砕物を中央部側(排出口5側)に寄せ集め、回転軸25の他方向の回転により破砕物を処理槽11の両側に拡散させるようになっている。処理槽11の内部には発酵菌が投入され、破砕手段21は、使用済み紙衛生用品を破砕及び裁断しながら発酵菌と共に攪拌し、発酵処理を行わせる。 As described above, the crushing means 21 can crush and cut the used paper sanitary goods while stirring the rotating shaft 25 while driving.

The heating means 22 includes a heating unit 51 including a heater, an electric heater, and the like, and includes a hot air reservoir 52 that stores the oxygen-containing gas heated by the heating unit 51. A plurality of injection pipes 53 extending from the hot air reservoir 52 toward the lower side in the vertical direction inside the processing tank 11 are provided, and the heated oxygen-containing gas is injected from the hot air reservoir 52 through the injection pipe 53 into the processing tank 11. The When the heated oxygen-containing gas is injected from the injection pipe 53, the inside of the processing tank 11 is uniformly heated to a desired state by the oxygen-containing gas.
 酸素含有ガスにより処理槽11の内部が加熱されることにより、破砕手段21によって破砕された破砕物を発酵させる際の発酵菌の活性が促されると共に、破砕物が乾燥されて発酵処理物となる。また、処理槽11の内部の発酵処理物が加熱殺菌されると共に、発酵処理物の残留水分が乾燥されて処理生成物となる。加熱手段22では加熱部51により、発酵菌の活性化や、発酵処理物を乾燥させる温度になるように酸素含有ガスの温度が制御されると共に、発酵処理物に付着した微生物を死滅又は不活性化すると共に、発酵処理物に残留した水分を乾燥させる温度になるように酸素含有ガスの温度が制御される。 When the inside of the treatment tank 11 is heated by the oxygen-containing gas, the activity of the fermenting bacteria at the time of fermenting the crushed material crushed by the crushing means 21 is promoted, and the crushed material is dried to become a fermented material. . Moreover, while the fermentation processed material inside the processing tank 11 is heat-sterilized, the residual water | moisture content of a fermentation processed material is dried and it becomes a processed product. In the heating means 22, the temperature of the oxygen-containing gas is controlled by the heating unit 51 so as to reach the temperature for activating the fermented bacteria and drying the fermented product, and kill or inactivate microorganisms attached to the fermented product. At the same time, the temperature of the oxygen-containing gas is controlled so that the moisture remaining in the fermented product is dried.
 上述した処理装置2では、投入口12から処理槽11の内部に使用済み紙衛生用品が投入され、駆動モータ27の駆動により回転軸25を一方向、他方向に回転させる。回転軸25の駆動回転により、第1回転羽根31の第1回転刃32及び第2回転羽根41の第2回転刃42と、第1固定刃36及び第2固定刃46との間で使用済み紙衛生用品が破砕・裁断され、所望の大きさに細分化された破砕物が製造される。 In the processing apparatus 2 described above, used paper sanitary goods are input into the processing tank 11 from the input port 12, and the rotating shaft 25 is rotated in one direction and the other direction by driving the drive motor 27.

Paper sanitary goods are crushed and cut to produce a crushed product that is subdivided into a desired size.
 この時、回転軸25の一方側の駆動回転により破砕物が回転軸25の中央部側(排出口5側)に寄せ集められ、回転軸25の他方側の駆動回転により破砕物が回転軸25の両端部側に拡散される。そして、加熱手段22により破砕物が加熱されて発酵処理物とされ、発酵処理物が所定時間加熱殺菌されて処理生成物とされる。 At this time, the crushed material is gathered to the central side (the discharge port 5 side) of the rotating shaft 25 by driving rotation on one side of the rotating shaft 25, and the crushed material is rotated to the rotating shaft 25 by driving rotation of the other side of the rotating shaft 25. It is diffused to the both end sides. Then, the crushed material is heated by the heating means 22 to be a fermented processed product, and the fermented processed product is sterilized by heating for a predetermined time to be a processed product.
 回転軸25の一方側の駆動回転により処理生成物が排出口5側に集められ、排出口5を開放することで、第1排出補助羽根35及び第2排出補助羽根45により処理生成物がシュート6(図1参照)を介してコンベア4(図1参照)に排出される。処理生成物はコンベア4(図1参照)によりペレット形成装置3(図1参照)に送られる。 The processing product is collected on the discharge port 5 side by the driving rotation of one side of the rotary shaft 25, and the processing product is shot by the first discharge auxiliary blade 35 and the second discharge auxiliary blade 45 by opening the discharge port 5. It is discharged to the conveyor 4 (see FIG. 1) via 6 (see FIG. 1). The processed product is sent to the pellet forming apparatus 3 (see FIG. 1) by the conveyor 4 (see FIG. 1).

Processing products are fed into the hopper 8 from a chain conveyor 9 (see FIG. 1). A screw conveyor 55 is provided at the outlet of the hopper 8, and a certain amount of processed product is sent from the hopper 8 to the fuel pellet forming unit 20 by the screw conveyor 55. The fuel pellet forming unit 20 forms the processed product as fuel pellets, and the formed fuel pellets are discharged from the pellet discharge port 16 and discharged by the discharge conveyor 10 (see FIG. 1).
 図8、図9に基づいて燃料ペレット形成部20を説明する。 The fuel pellet forming unit 20 will be described with reference to FIGS.
 図8、図9に示すように、燃料ペレット形成部20の円筒本体61の下部には肉厚円盤リング状のダイス62が取り付けられ、ダイス62には中心軸方向(図8中上下方向・図9中紙面に垂直な方向)に貫通する型穴63が多数形成されている。ダイス62の中心軸を中心に回動する回転筒64がダイス62の中心部に備えられ、回転筒64は図示しない駆動手段により所定の回転速度で回動する。 As shown in FIGS. 8 and 9, a thick disc ring-shaped die 62 is attached to the lower part of the cylindrical main body 61 of the fuel pellet forming portion 20, and the die 62 has a central axial direction (vertical direction in FIG. A number of mold cavities 63 penetrating in a direction perpendicular to the middle sheet surface 9 are formed. A rotating cylinder 64 that rotates about the central axis of the die 62 is provided at the center of the die 62, and the rotating cylinder 64 is rotated at a predetermined rotational speed by a driving means (not shown).
 回転筒64の筒部の4箇所には、水平方向に延びる中心軸を中心に回転するローラ65が備えられている。ローラ65には歯型状の凹凸が形成され、回転筒64が回動することによりダイス62の盤面(型穴63が形成されている部位)を転動するようになっている。ダイス62の盤面に対するローラ65の接触圧力は、ダイス62に対する回転筒64の取り付き高さにより調整される。 At four locations of the cylindrical portion of the rotating cylinder 64, there are provided rollers 65 that rotate about a central axis extending in the horizontal direction. The roller 65 is formed with tooth-shaped irregularities, and the rotary cylinder 64 rotates to roll on the surface of the die 62 (portion where the mold hole 63 is formed). The contact pressure of the roller 65 with respect to the surface of the die 62 is adjusted by the mounting height of the rotating cylinder 64 with respect to the die 62.
 尚、回転筒64を固定状態に設けると共にダイス62を回動自在に設け、ダイス62を回動させることでダイス62の盤面に対してローラ65を転動させることも可能である。 In addition, it is also possible to roll the roller 65 with respect to the disk surface of the die 62 by providing the rotary cylinder 64 in a fixed state and providing the die 62 so as to be rotatable.
 ホッパ8の処理生成物71はスクリューコンベア55(図7参照)により円筒本体61の内部に投入され、ローラ65の間からダイス62の盤面の上に供給される。円筒本体61の回動によりローラ65がダイス62の盤面を転動することにより、処理生成物71が多数の型穴63に圧入される。ローラ65の転動により処理生成物71が順次圧入され、摩擦熱により燃料ペレット72が形成される。 The processing product 71 of the hopper 8 is put into the cylindrical main body 61 by the screw conveyor 55 (see FIG. 7), and supplied from between the rollers 65 onto the surface of the die 62. As the cylindrical body 61 rotates, the roller 65 rolls on the surface of the die 62, so that the processed product 71 is press-fitted into the many mold cavities 63. The processing product 71 is sequentially press-fitted by the rolling of the roller 65, and the fuel pellet 72 is formed by frictional heat.
 ダイス62の型穴63で形成された燃料ペレット72は、ペレット排出口16(図6参照)から排出されて排出コンベア10(図1参照)により排出され、所定の容器等に収容されて燃料として需要場所に搬送される。 The fuel pellets 72 formed in the mold cavity 63 of the die 62 are discharged from the pellet discharge port 16 (see FIG. 6), discharged by the discharge conveyor 10 (see FIG. 1), and stored in a predetermined container or the like as fuel.
