Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

As shown in Fig. 1, the pulverizer 1 having a stirring function includes a pulverizing unit 2, a stirring tank 3, and a unit pump 4. The pulverizing unit 2, the stirring tank 3, and the unit pump 4 are supported and held by a stage 20 which serves as a gantry provided on the floor F. The table 20 is disposed in the order of the pulverizing portion 2, the stirring tank 3, and the unit pump 4 from the top.

An input port 2A for inserting an organic material into the upper portion of the pulverizing portion 2 is provided. Inside the pulverizing unit 2, a rotor and a motor (none of which are not shown) are provided. Numerous teeth are placed on the rotating rotor. In the pulverizing unit 2, the rotating rotor is rotationally driven by a motor, and the organic processed material fed from the inlet 2A is pulverized by the teeth of the rotating rotor. In other words, the pulverizing unit 2 pulverizes the organic processed material fed from the inlet 2A. The pulverized organic treatment will be dropped and then sent to the agitation tank 3.

The agitation tank 3 is a mixture of the organic material to be pulverized in the pulverization unit 2 with a liquid (that is, water). The agitated organic treatment product is mixed with water, stirred, and sent to the monomer pump 4.

As shown in FIGS. 2A and 2B, the agitation tank 3 is a cylindrical treatment tank as a whole. The agitation tank 3 is constituted by a cylindrical side wall 10 (inner wall 10A) and a bottom surface 11 surrounded by the inside.

As shown in Fig. 2B, in the upper portion of the agitation vessel 3, an inlet port 12 connected to the pulverizing portion 2 is provided as an opening. The organic processed material crushed by the crushing unit 2 is supplied from the inlet port 12.

On the other hand, an inflow port 13 is provided in the inner wall 10A of the side wall 10. As shown in FIG. 2A, the inflow port 13 is connected to the pipe 13A. In the pipe 13A, water supply is started from a supply source (not shown), and the water flows into the agitation tank 3 from the inflow port 13.

As shown in FIG. 2A, the inflow port 13 is oriented in the horizontal direction and along the inner wall 10A. Therefore, the water system flows through the agitation tank 13 from the inflow port 13 in the circumferential direction. More specifically, in the position where the central axis O of the side wall of the cylindrical shape is point-symmetric, the inflow port 13 is provided in two.

The bottom surface 11 is inclined, and a plurality of through holes 14 are provided in one portion of the bottom surface 11. More specifically, the bottom surface 11 is composed of two inclined faces 11A, 11B. The inclined faces 11A, 11B have a shape in which the line segments at the lowermost edge are connected. As shown in Fig. 2C, a plurality of through holes 14 are arranged on the inclined surface 11A on one side. The size of the through hole 14 is a very small amount of organic material that can be transported by the unit pump 4.

As shown in FIG. 2B, the discharge portion 15 is provided at a lower portion of the stirring tank 3 (below the inclined surface 11A). The discharge unit 15 sends the organic processed material of the plurality of through holes 14 provided through the bottom surface 11 (inclined surface 11A) to the unit pump 4.

The so-called unit pump 4 is also known as a uniaxial eccentric screw pump. The pump has a space between the eccentric screw and the outer material surrounding the screw. According to the rotation of the eccentric screw, the material is sucked into the space from the outside, and then the material taken into the space is fixed. Directions are introduced.

The unit pump 4 may be formed of a metal male screw portion having a circular cross section, and the metal male screw portion is located in a female screw portion of an oblong cross section formed of an elastic material as a raw material. The unit pump 4 can be widely transferred from a material having a low viscosity and a fluidity to a substance having a high viscosity and a lack of fluidity by rotating the male screw portion.

The motor 4A is provided to the unit pump 4. The unit pump 4 rotates the eccentric screw described above by driving the motor 4A to feed the organic processed material through the pipe 5 to the processing tank (not shown) in the lower stage. The solubilization treatment before the fermentation of methane and the fermentation of methane and the like are carried out in the treatment tank of the lower stage.

Next, the operation of the crusher 1 having the stirring function will be described.

First, the organic processed material is introduced into the pulverizing unit 2 from the input port 2A by the operator, and the organic processed material to be charged is pulverized. The pulverized organic processed material is sent to the stirring tank 3.

The organic treated material sent to the stirring tank 3 is mixed and stirred with water flowing in from the inflow port 13 of the stirring tank 3. As shown in Fig. 3, the water containing the organically treated material is rotated downward in the stirring tank and moved downward toward the bottom surface 11. Upon reaching the bottom surface 11, the water containing the organic treatment material will climb the inclined faces 11A, 11B, even climb the inner wall 10A, and then merge with the new water flowing in from the inflow port 13 to become more easily stirred. As a result, in the agitation tank 3, the water containing the organically treated material forms a swirling flow in the horizontal direction and a swirling flow in the vertical direction, thereby stirring the organic processed material.

Between the agitation flows, the organic processed material which is contained in the water advancing in the inclined surface 11A and is pulverized and stirred to a very small size is sent to the discharge portion 15 through the through hole 14. Since the organic processed material is finely pulverized and stirred to be extremely small, it is not solidified when discharged from the discharge portion 15, and is sent to the unit pump 4 together with water.

In the case where the object to be transported is a mixture of water and an organic treatment, the unit pump 4 has the property of first attracting and transporting water. However, in the present embodiment, the agitation tank 3 is provided between the pulverizing portion 2 and the unit pump 4, because water is supplied thereto, and solidification of the organic treatment material can be prevented in the front stage of the unit pump 4. According to this, it is possible to prevent the front stage of the unit pump 4 from being clogged and the organic processed material from being transported by the unit pump 4.

As described in detail above, according to the present embodiment, the pulverized organic treatment material is mixed with the liquid in the agitation tank 3, stirred, and becomes very fine. After passing through the plurality of holes 14, it can be sent to the unit pump 4. Therefore, the organic treatment can be prevented from being clogged in the front stage of the unit pump 4.

Further, according to the present embodiment, the bottom surface 11 has a valley shape in which the two inclined surfaces 11A and 11B are connected by the line segment of the lowermost edge thereof, and the plurality of through holes 14 are formed in the inclined surface 11A on one side. Since the shape of the bottom surface 11 is formed in a valley shape, a flow from bottom to top can be generated in the agitation tank 3. According to this, the organic treatment material can be more stirred and made finer.

Further, since only the organic processed material can be sent to the unit pump 4 through the plurality of through holes 14, the unitary pump 4 can smoothly carry the organic processed material to the processing tank of the lower stage. Further, since only a plurality of through holes 14 are provided on the inclined surface 11A on one side, only the supplied water is not advanced to the unit pump 4.

Further, a plurality of through holes 14 are provided only on the inclined surface 11A, and the through holes 14 are not provided in the inclined surface 11B, so that the water for stirring in the stirring tank 3 is not sent to the unit pump 4 first. .

Further, the bottom surface of the agitation tank 3 is not limited to the above-described embodiment. For example, the shape of the inverted conical shape is also possible, and the inclination of the single direction is also possible.

Further, according to the present embodiment, the inflow port 13 is provided at a position symmetrical with respect to the central axis O of the cylindrical stirring tank 3, and is provided in plural numbers. According to this, the liquid (water) within the agitation tank 3 can be uniformly present. Further, the through hole 14 is also provided in the line segment of the lowermost edge of the inclined surface 11A in order to prevent the mixture of the organic treated material and the water from accumulating in the bottom portion.

Furthermore, the positions of the respective inflow ports 13 are not limited to the same height. There are several items available on the top and bottom.

 Furthermore, for the above embodiment, the number of the inflow ports 13 is two, but not limited thereto. It is also possible that only one or more of the inflow ports 13 are provided. In this case, each of the inflow ports 13 may be provided at a position symmetrical with respect to the central axis O of the cylindrical agitating tank 3.  

The inclination angle of the bottom surface 11 can be arbitrarily set. Further, the size of the through hole 14 can be appropriately determined based on the capability of the unit pump 4.

The present invention is capable of various embodiments and modifications of the embodiments of the invention. Further, the above-described embodiments are intended to describe the present invention and are not intended to limit the scope of the invention. That is, the scope of the invention is indicated by the scope of the claims and not by the embodiments. Further, various modifications made within the scope of the invention and the scope of the invention are considered to be within the scope of the invention.

Further, in the case of the present application, priority is claimed on the basis of the Japanese Patent Application No. 2016-195578 filed on Oct. 3, 2016. The specification, patent application, and drawings of the Japanese Patent Application No. 2016-195578 are incorporated herein by reference.
