Description

撹拌機能付き破砕機Crusher with stirring function
　本発明は、撹拌機能付き破砕機に関する。 The present invention relates to a crusher with a stirring function.
　有機性廃棄物を用いたメタン発酵を行う場合には、その前に有機性廃棄物を細かく砕き、可溶化処理を行うなどして、有機性廃棄物をメタン発酵し易い状態にする必要がある。そこで、有機性廃棄物は、まず、破砕機で破砕された後、モーノポンプで可溶化処理を行う処理槽に送られる（例えば、特許文献１参照）。 When performing methane fermentation using organic waste, it is necessary to make the organic waste easily methane-fermentable by pulverizing the organic waste and performing solubilization treatment before that. . Therefore, the organic waste is first crushed by a crusher and then sent to a treatment tank in which solubilization treatment is performed by a mono pump (see, for example, Patent Document 1).
特開２０１６－１０７３３号公報JP 2016-10733 A
　しかしながら、モーノポンプは、破砕された有機性廃棄物と液体とが混合した処理物については、有機性廃棄物よりも液体の方を先に吸引して送ってしまう傾向がある。これにより、破砕機とモーノポンプとの間に残った有機性廃棄物が残留して、管内で固形化しやすくなり、破砕機からモーノポンプに処理物を送りにくくなる場合がある。 However, the MONO pump tends to suck and send the liquid before the organic waste with respect to the processed product in which the crushed organic waste and the liquid are mixed. As a result, the organic waste remaining between the crusher and the mono pump remains and is easily solidified in the pipe, and it may be difficult to send the processed material from the crusher to the mono pump.
　本発明は、上記実情に鑑みてなされたものであり、モーノポンプの前段で有機性廃棄物が詰まるのを防止することができる撹拌機能付き破砕機を提供することを目的とする。 The present invention has been made in view of the above circumstances, and an object thereof is to provide a crusher with a stirring function capable of preventing clogging of organic waste at the front stage of a mono pump.

　以下、本発明の実施の形態について、図面を参照して詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
　図１に示すように、撹拌機能付き破砕機１は、破砕部２と、撹拌槽３と、モーノポンプ４と、を備える。破砕部２と、撹拌槽３と、モーノポンプ４は、床Ｆの上に設置された架台であるステージ２０に支持され、ステージ２０に保持されている。ステージ２０では、上から、破砕部２、撹拌槽３、モーノポンプ４の順で配置されている。 As shown in FIG. 1, the crusher 1 with a stirring function includes a crushing unit 2, a stirring tank 3, and a Mono pump 4. The crushing unit 2, the stirring tank 3, and the Mono pump 4 are supported by the stage 20 that is a pedestal installed on the floor F and are held by the stage 20. In the stage 20, the crushing part 2, the stirring tank 3, and the Mono pump 4 are arrange | positioned in order from the top.
　破砕部２の上部には、有機性処理物を投入する投入口２Ａが設けられている。破砕部２の内部には、回転ロータ及びモータ（いずれも不図示）が設けられている。回転ロータには無数の歯が設けられている。破砕部２では、モータにより、回転ロータを回転駆動し、回転ロータの歯で投入口２Ａから投入された有機性処理物が破砕される。すなわち、破砕部２は、投入口２Ａから投入された有機性処理物を破砕する。破砕された有機性処理物は、落下して、撹拌槽３に送られる。 At the upper part of the crushing part 2, there is provided an inlet 2 </ b> A for introducing an organic treatment product. A rotating rotor and a motor (both not shown) are provided inside the crushing unit 2. The rotating rotor is provided with a myriad of teeth. In the crushing unit 2, the rotating rotor is rotationally driven by a motor, and the organic processed material charged from the charging port 2 </ b> A is crushed by the teeth of the rotating rotor. That is, the crushing part 2 crushes the organic processed material input from the input port 2A. The crushed organic processed material falls and is sent to the stirring tank 3.
　撹拌槽３は、破砕部２で破砕された有機性処理物を、液体、すなわち水で撹拌する。撹拌された有機性処理物は水と混合され撹拌された後、モーノポンプ４へ送られる。 The stirring tank 3 stirs the organic processed material crushed by the crushing unit 2 with a liquid, that is, water. The stirred organic processed product is mixed with water and stirred, and then sent to the MONO pump 4.
　図２Ａ及び図２Ｂに示すように、撹拌槽３は、全体として円筒形状の処理槽である。撹拌槽３は、円筒形状の側壁１０（内壁１０Ａ）と、底面１１とで囲まれた内部で構成される。 2A and 2B, the stirring tank 3 is a cylindrical processing tank as a whole. The agitation tank 3 includes an inside surrounded by a cylindrical side wall 10 (inner wall 10 </ b> A) and a bottom surface 11.
　図２Ｂに示すように、撹拌槽３の上部には、破砕部２と連結された投入口１２が開口している。破砕部２で破砕された有機性処理物は、投入口１２から投入される。 As shown in FIG. 2B, a charging port 12 connected to the crushing unit 2 is open at the top of the stirring tank 3. The organic processed material crushed by the crushing unit 2 is input from the input port 12.
　一方、側壁１０の内壁１０Ａには、流入口１３が設けられている。図２Ａに示すように、流入口１３は、配管１３Ａに連結されている。配管１３Ａには、不図示の供給源から水が供給されており、その水が流入口１３から撹拌槽３内に流入する。 On the other hand, an inlet 13 is provided on the inner wall 10A of the side wall 10. As shown in FIG. 2A, the inflow port 13 is connected to a pipe 13A. Water is supplied to the pipe 13 </ b> A from a supply source (not shown), and the water flows into the stirring tank 3 from the inlet 13.
　図２Ａに示すように、流入口１３は、水平方向を向き、内壁１０Ａに沿っている。したがって、水は、撹拌槽３内を流入口１３から周方向に回転するように流れる。より具体的には、流入口１３は、円筒形状の側壁の中心軸Ｏに対して点対称な位置に２つ設けられている。 As shown in FIG. 2A, the inflow port 13 faces the horizontal direction and is along the inner wall 10A. Therefore, water flows in the stirring tank 3 so as to rotate in the circumferential direction from the inflow port 13. More specifically, two inflow ports 13 are provided at positions symmetrical with respect to the central axis O of the cylindrical side wall.
　底面１１は傾斜しており、一部に複数の貫通穴１４が設けられている。より詳細には、底面１１は、２つの傾斜面１１Ａ，１１Ｂから成り、傾斜面１１Ａ，１１Ｂは、最下縁の線分で連結した形状を有している。一方の傾斜面１１Ａには、図２Ｃに示すように、複数の貫通穴１４が配列されている。貫通穴１４の径は、モーノポンプ４によって送ることができるような十分に小さな有機性処理物が通過することができる大きさとなっている。 The bottom surface 11 is inclined and a plurality of through holes 14 are provided in part. More specifically, the bottom surface 11 includes two inclined surfaces 11A and 11B, and the inclined surfaces 11A and 11B have a shape connected by a line segment at the lowermost edge. On one inclined surface 11A, as shown in FIG. 2C, a plurality of through holes 14 are arranged. The diameter of the through hole 14 is such a size that a sufficiently small organic processed material that can be sent by the MONO pump 4 can pass therethrough.
　図２Ｂに示すように、撹拌槽３の下部（傾斜面１１Ａの下方）には、排出部１５が設けられている。排出部１５は、底面１１（傾斜面１１Ａ）に設けられた複数の貫通穴１４を通過した有機性処理物を、モーノポンプ４へ送る。 As shown in FIG. 2B, a discharge unit 15 is provided in the lower part of the stirring tank 3 (below the inclined surface 11A). The discharge unit 15 sends the organic processed material that has passed through the plurality of through holes 14 provided on the bottom surface 11 (inclined surface 11 </ b> A) to the MONO pump 4.
　モーノポンプ４とは、いわゆる一軸偏心ねじポンプとして知られている。このポンプは、偏心ねじ及びそのねじを取り囲む外側部材との間に空間を有しており、偏心ねじを回転させることによって、その空間内に外部から材料を吸い込み、さらにこの空間内に取り込んだ材料を一定方向へ押し出す。 The Mono pump 4 is known as a so-called uniaxial eccentric screw pump. This pump has a space between the eccentric screw and the outer member surrounding the screw, and by rotating the eccentric screw, the material is sucked into the space from the outside, and the material taken into the space Is pushed out in a certain direction.
　モーノポンプ４は、弾性材料を素材として成る長円形断面の雌ねじ部内に真円断面の金属製雄ねじ部を具えて成るものであってもよい。モーノポンプ４は、雄ねじ部を回転させることにより、粘度が低く流動性に富んだ物質から、粘度が高く流動性が乏しい物質まで幅広く移送することができる。 The MONO pump 4 may include a metal external thread portion having a perfect circular cross section in an internal thread portion having an elliptical cross section made of an elastic material. By rotating the male screw portion, the MONO pump 4 can widely transfer a material having a low viscosity and a high fluidity to a material having a high viscosity and a low fluidity.
　モーノポンプ４には、モータ４Ａが設けられている。モーノポンプ４は、モータ４Ａの駆動により上記偏心ねじを回転させて、有機性処理物を、配管５を介して、下段の処理槽（不図示）へ送る。下段の処理槽では、メタン発酵を行う前の可溶化処理や、メタン発酵などが行われる。 The MONO pump 4 is provided with a motor 4A. The MONO pump 4 rotates the eccentric screw by driving the motor 4 </ b> A, and sends the organic processing material to the lower processing tank (not shown) via the pipe 5. In the lower treatment tank, solubilization treatment before methane fermentation, methane fermentation, and the like are performed.
　次に、撹拌機能付き破砕機１の動作について説明する。 Next, the operation of the crusher 1 with a stirring function will be described.
　まず、破砕部２に有機性処理物が作業者によって投入口２Ａから投入され、投入された有機性処理物の破砕が行われる。破砕された有機性処理物は、撹拌槽３に送られる。 First, an organic processing product is input to the crushing unit 2 from the input port 2A by an operator, and the input organic processing product is crushed. The crushed organic processed product is sent to the stirring tank 3.
　撹拌槽３に送られた有機性処理物は、撹拌槽３の流入口１３から流入する水と混合し、撹拌される。図３に示すように、有機性処理物を含む水は、撹拌槽３内を旋回しつつ、底面１１に向けて下っていく。底面１１まで到達すると、有機性処理物を含む水は傾斜面１１Ａ、１１Ｂを登っていき、さらに内壁１０Ａを登り、新たに流入口１３から流入される水と合流して、さらに撹拌されやすい状態となる。このように、撹拌槽３内では、有機性処理物を含む水の水平方向の回転の流れと、垂直方向の回転の流れが形成され、有機性処理物の撹拌が行われる。 The organic processed material sent to the stirring tank 3 is mixed with water flowing from the inlet 13 of the stirring tank 3 and stirred. As shown in FIG. 3, the water containing the organic treatment product descends toward the bottom surface 11 while swirling in the stirring tank 3. When reaching the bottom surface 11, the water containing the organic treatment product climbs the inclined surfaces 11 </ b> A and 11 </ b> B, further climbs the inner wall 10 </ b> A, and merges with the water newly introduced from the inlet 13, and is more easily stirred. It becomes. Thus, in the agitation tank 3, a horizontal rotation flow and a vertical rotation flow of water containing the organic treatment product are formed, and the organic treatment product is agitated.
　この撹拌の流れの間に、傾斜面１１Ａ上を進む水に含まれ、砕かれ撹拌され十分に細かくなった有機性処理物は、貫通穴１４を通過して排出部１５に送られる。この有機性処理物は、細かく砕かれ、撹拌され十分に小さくなっているので、排出部１５から排出され、固形化せず、水とともにモーノポンプ４に送られる。 During this stirring flow, the organic processed material contained in the water traveling on the inclined surface 11A, crushed and stirred to become sufficiently fine passes through the through hole 14 and is sent to the discharge unit 15. Since this organic processed product is finely crushed and stirred to be sufficiently small, it is discharged from the discharge unit 15 and is not solidified and sent to the MONO pump 4 together with water.
　モーノポンプ４では、送る対象が水と有機性処理物との混合物である場合、水の方を先に吸引して送る性質を有している。しかしながら、本実施の形態では、破砕部２とモーノポンプ４との間に撹拌槽３を設け、ここに水を供給するので、モーノポンプ４の前段において、有機性処理物が固形化するのを防いでいる。これにより、モーノポンプ４の前段が詰まり有機性処理物がモーノポンプ４で送られなくなるのを防止している。 In the MONO pump 4, when the object to be sent is a mixture of water and an organic processed product, it has a property of sucking and sending water first. However, in the present embodiment, the stirring tank 3 is provided between the crushing section 2 and the Mono pump 4 and water is supplied thereto, so that the organic processing product is prevented from solidifying in the previous stage of the Mono pump 4. Yes. This prevents the former stage of the MONO pump 4 from being clogged and preventing the organic processing product from being sent by the MONO pump 4.
　以上詳細に説明したように、本実施の形態によれば、破砕された有機性処理物を、撹拌槽３内で液体と混合し、撹拌し、十分に細かくして複数の貫通穴１４を通過する状態にしてから、モーノポンプ４に送ることができるので、モーノポンプ４の前段で有機性処理物が詰まるのを防止することができる。 As described above in detail, according to the present embodiment, the crushed organic processed product is mixed with the liquid in the stirring tank 3, stirred, and sufficiently finely passed through the plurality of through holes 14. Since it can be sent to the MONO pump 4 after being in the state to be made, it is possible to prevent the organic processing material from being clogged at the front stage of the MONO pump 4.
　また、本実施の形態によれば、底面１１は、２つの傾斜面１１Ａ，１１Ｂが最下縁の線分で連結した谷形形状を有しており、一方の傾斜面１１Ａに複数の貫通穴１４が設けられている。底面１１の形状を谷形とすることにより、撹拌槽３内に下から上への流れを作りだすことができる。これにより、有機性処理物をさらに撹拌し、細かくすることができる。 Further, according to the present embodiment, the bottom surface 11 has a valley shape in which two inclined surfaces 11A and 11B are connected by a line segment at the lowermost edge, and a plurality of through holes are formed in one inclined surface 11A. 14 is provided. By making the shape of the bottom surface 11 into a valley shape, a flow from the bottom to the top can be created in the stirring tank 3. Thereby, an organic processed material can be further stirred and refined.
　また、複数の貫通穴１４を通過した有機性処理物のみをモーノポンプ４に送ることができるので、モーノポンプ４を用いてスムーズに有機性処理物を下段の処理槽に送ることができる。また、一方の傾斜面１１Ａだけに複数の貫通穴１４を設けることにより、供給した水だけが先にモーノポンプ４の方に行かないようにすることができる。 Moreover, since only the organic processed material that has passed through the plurality of through holes 14 can be sent to the MONO pump 4, the organic processed material can be smoothly sent to the lower processing tank using the MONO pump 4. Further, by providing the plurality of through holes 14 only on one inclined surface 11A, it is possible to prevent only the supplied water from going to the mono pump 4 first.
　なお、傾斜面１１Ａにだけ複数の貫通穴１４を設け、傾斜面１１Ｂに貫通穴１４を設けないのは、撹拌槽３内で撹拌に用いられる水が、先にモーノポンプ４の方に送られないようにするためである。 The reason why the plurality of through holes 14 are provided only on the inclined surface 11A and the through holes 14 are not provided on the inclined surface 11B is that water used for stirring in the stirring tank 3 is not sent to the mono pump 4 first. It is for doing so.
　なお、撹拌槽３の底面は、上記実施の形態のものに限られない。例えば、逆円錐状のものであってもよいし、単に一方向に傾斜しているものであってもよい。 Note that the bottom surface of the agitation tank 3 is not limited to that in the above embodiment. For example, it may have an inverted conical shape or may simply be inclined in one direction.
　また、本実施の形態によれば、流入口１３は、円筒形状の撹拌槽３の中心軸Ｏに対して点対称な位置に複数設けられている。これにより、撹拌槽３内で液体（水）が均一に存在できるようになる。また、傾斜面１１Ａの最下縁の線分にも貫通穴１４を設けたのは、この谷底の部分に、有機性処理物及び水の混合物が溜まらないようにするためにである。 Further, according to the present embodiment, a plurality of the inlets 13 are provided at point-symmetrical positions with respect to the central axis O of the cylindrical stirring tank 3. Thereby, a liquid (water) can exist uniformly in the stirring tank 3. Also, the reason why the through hole 14 is provided in the lowermost line segment of the inclined surface 11A is to prevent the mixture of the organic treatment product and water from accumulating in the valley bottom.
　なお、各流入口１３の位置は、同じ高さに限られない。上下に幾つか備えるようにしてもよい。 In addition, the position of each inflow port 13 is not restricted to the same height. You may make it provide some up and down.
　なお、上記実施の形態では、流入口１３の数を２つとしたが、これには限られない。流入口１３は、１つであってもよいし、３つ以上であってもよい。この場合でも、各流入口１３は、円筒形状の撹拌槽３の中心軸Ｏに対して点対称な位置に設けられるようにしてもよい。 In the above embodiment, the number of inflow ports 13 is two, but the present invention is not limited to this. One inflow port 13 may be sufficient and three or more may be sufficient. Even in this case, each inflow port 13 may be provided at a point-symmetrical position with respect to the central axis O of the cylindrical stirring tank 3.
　底面１１の傾斜角度については、任意に設定することができる。また、貫通穴１４の大きさも、モーノポンプ４の能力に基づいて、適宜決定することができる。 The inclination angle of the bottom surface 11 can be arbitrarily set. Further, the size of the through hole 14 can also be appropriately determined based on the capability of the Mono pump 4.
　この発明は、この発明の広義の精神と範囲を逸脱することなく、様々な実施の形態及び変形が可能とされるものである。また、上述した実施の形態は、この発明を説明するためのものであり、この発明の範囲を限定するものではない。すなわち、この発明の範囲は、実施の形態ではなく、特許請求の範囲によって示される。そして、特許請求の範囲内及びそれと同等の発明の意義の範囲内で施される様々な変形が、この発明の範囲内とみなされる。 The present invention is capable of various embodiments and modifications without departing from the broad spirit and scope of the present invention.
