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 is provided with a pulverizing section 2, a stirring tank 3, and a monomer pump 4. The pulverizing section 2, the stirring tank 3, and the unit pump 4 are supported and held by a stage 20 (Stage), which serves as a stand installed on the floor F. The table 20 is arranged from the top in the order of the pulverizing section 2, the stirring tank 3, and the unit pump 4.

On the upper part of the pulverizing section 2, a feeding port 2A for feeding an organic processed material is provided. A rotor and a motor (neither of which is shown) are provided inside the crushing unit 2. Countless teeth are provided on the rotating rotor. In the pulverizing unit 2, the rotating rotor is driven to rotate by a motor, and the teeth of the rotating rotor are used to pulverize the organic processed material input from the input port 2A. That is, the pulverizing unit 2 pulverizes the organic processed material input from the input port 2A. The pulverized organic processed material is dropped and sent to the stirring tank 3.

The stirring tank 3 stirs the organic processed material to be pulverized in the pulverizing section 2 with a liquid (that is, water). The stirred organic treatment system is mixed with water, stirred, and then sent to the monomer pump 4.

As shown in FIGS. 2A and 2B, the stirring tank 3 is a processing tank having a cylindrical shape as a whole. The stirring tank 3 is constituted by an inner portion surrounded by a cylindrical side wall 10 (inner wall 10A) and a bottom surface 11.

As shown in FIG. 2B, an input port 12 connected to the pulverizing unit 2 is provided as an opening in the upper part of the stirring tank 3. The organic processed material pulverized by the pulverizing section 2 is input from the input 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. Water is supplied to the piping 13A from a supply source (not shown), and the water flows from the inflow port 13 into the stirring tank 3.

As shown in FIG. 2A, the inflow port 13 is oriented horizontally and along the inner wall 10A. Therefore, the water system flows into the stirring tank 13 from the inflow port 13 in a circumferential direction. More specifically, at a position where the central axis O of the cylindrical side wall is point-symmetric, the inflow ports 13 are provided in two.

The bottom surface 11 is inclined, and a plurality of through holes 14 are provided in a part of the bottom surface 11. More specifically, the bottom surface 11 is composed of two inclined surfaces 11A and 11B. The inclined surfaces 11A and 11B have a shape connected at the lowermost line segment. As shown in FIG. 2C, a plurality of through-holes 14 are arranged in the inclined surface 11A on one side. The diameter of the through hole 14 is such that a very small organic processed material that can be conveyed by the monomer pump 4 can pass through.

As shown in FIG. 2B, the discharge portion 15 is provided at the lower portion (below the inclined surface 11A) of the stirring tank 3. The discharge unit 15 sends the organic processed material passing through the plurality of through holes 14 provided in 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. This pump system has a space between the eccentric screw and the outer material surrounded by 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 removed from a certain distance. Push out direction.

The unit pump 4 may also be configured by a male screw portion having a regular circular cross section, and the metal male screw portion is located within a female screw portion of an oval cross section made of an elastic material as a raw material. The unit pump 4 can be widely transferred from a low-viscosity substance with a high fluidity to a high-viscosity substance without a fluidity by rotating the male screw portion.

The motor 4A is provided in the unit pump 4. The unit pump 4 is driven by the motor 4A to rotate the above-mentioned eccentric screw to pass the organic processed material through the pipe 5 to the processing tank (not shown) at the lower stage. The solubilization treatment before fermenting methane and fermenting methane are carried out in the lower processing tank.

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

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

The organic processed material sent to the stirring tank 3 is mixed and stirred together with the water flowing in from the inlet 13 of the stirring tank 3. As shown in Fig. 3, the water containing the organic processed material is moved downward in the bottom surface 11 while rotating in the stirring tank. Once the bottom surface 11 is reached, the water containing the organic processed material ascends on the inclined surfaces 11A and 11B, and even on the inner wall 10A, and then merges with the new water flowing from the inlet 13 to make it easier to stir. In this way, in the stirring tank 3, the water containing the organic processed material will form a horizontal rotating flow and a vertical rotating flow, and thus the organic processed material will be stirred.

During this stirring flow, the organic processed material contained in the water advancing on the inclined surface 11A and 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 become very small, it is not solidified when discharged from the discharge unit 15 and is sent to the monomer pump 4 together with water.

When the transport target is a mixture of water and an organic processed material, the monomer pump 4 has a property of first attracting and transporting water. However, in this embodiment, a stirring tank 3 is provided between the pulverizing unit 2 and the unit pump 4, because water is supplied here, and the solidification of the organic processed 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 monomer pump 4 from being clogged and the organic processed material from being transported by the monomer pump 4.

As described in detail above, according to this embodiment, the pulverized organic processed material is mixed with the liquid in the stirring tank 3 and stirred to become very fine and can pass through the plurality of holes 14 before being sent to the monomer pump 4 Therefore, it is possible to prevent the organic processed material from clogging in the front stage of the monomer pump 4.

In addition, according to this embodiment, the bottom surface 11 has a valley shape, which is the two inclined surfaces 11A, 11B connected by the lowermost line segment, and a plurality of through holes 14 are provided on one side of the inclined surface 11A. Since the shape of the bottom surface 11 is valley-shaped, a bottom-to-top flow can be generated in the stirring tank 3. Accordingly, the organic processed material can be further stirred and made finer.

In addition, since only the organic processed material can be sent to the monomer pump 4 through the plurality of through holes 14, the organic processed material can be smoothly transferred to the lower processing tank using the monomer pump 4. In addition, since the plurality of through holes 14 are provided in the inclined surface 11A on only one side, only the supplied water cannot be advanced to the unit pump 4.

Moreover, only a plurality of through holes 14 are provided on the inclined surface 11A, and no through holes 14 are provided on the inclined surface 11B, so that the water for stirring in the stirring tank 3 will not be sent to the monomer pump 4 first. .

In addition, the bottom surface of the stirring tank 3 is not limited to the above embodiment. For example, an inverted cone shape is also possible, and a single-direction inclination is also possible.

In addition, according to this aspect, the inflow port 13 is provided at a plurality of points symmetrically positioned with respect to the central axis O of the cylindrical stirring tank 3. According to this, the liquid (water) inside the stirring tank 3 can exist uniformly. The through hole 14 is also provided on the line segment of the lowermost edge of the inclined surface 11A, so that the mixture of the organic processed material and water does not accumulate on the bottom portion.

The positions of the inflow ports 13 are not limited to the same height. You may have several up and down.

    Moreover, for the above-mentioned embodiment, although the number of the inflow ports 13 is two, it is not limited thereto. It is also possible to have only one or three or more inflow ports 13. In this case, each of the inflow ports 13 may be provided at a position symmetrical to the center axis O of the cylindrical stirring tank 3.    

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

The present invention can adopt various implementation forms and modifications without departing from the broad spirit and scope of the present invention. In addition, the above-mentioned embodiments are used to describe the present invention and do not limit the scope of the present invention. That is, the scope of the present invention is expressed by the scope of the patent application rather than the embodiment. Moreover, various modifications implemented within the scope of the patent application and the meaning of the equivalent invention are considered to be within the scope of the present invention.
