It is fixed to the bottom of the car and attached to the sink. Note that a faucet 14 is arranged above the sink 12.

A motor 1 is installed below the crushing chamber 9 so as to be surrounded by the bracket 2 fixed to the hopper 4. A shaft 5 extending upward from the motor 1 projects at the lower center of the crushing chamber 9. A rotating plate 6 is fixed to the shaft 5, and a plurality of rotating blades 7, 8 are attached to the outer periphery of the rotating plate 6 so as to face the crushing chamber 9. The fixed blade 3 is mounted in an annular shape outside the rotary blades 7 and 8 at the upper end of the bracket 2 so as to face the rotary blades 7 and 8.

As a result, the garbage introduced into the crushing chamber 9 from the inlet 10 is crushed by the rotary blades 7 and 8 and the fixed blade 3.

Hereinafter, an embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIG. In these drawings, the same members are denoted by the same reference numerals, and duplicate description is omitted.

(Embodiment 1) FIG. 1 is a cross-sectional view showing a pulverizing apparatus according to Embodiment 1 of the present invention, FIG. 2 is an explanatory view showing a rotational direction of a swirling flow in the pulverizing apparatus of FIG.
FIG. 3 is a sectional view showing a modified example of the pulverization processing apparatus of FIG.

In the crushing processing apparatus which is a disposer shown in FIG. 1, a crushing chamber 9 for crushing garbage (processed material) is formed in a cylindrical hopper 4. And
An opening 1 that opens above the crushing chamber 9 and into which garbage is introduced.
0 is provided. The input port 10 is
A cover 11 for opening and closing the cover is detachably attached. The lid 11 is formed with a through hole (not shown) for capturing kitchen waste and allowing water to pass therethrough.

The outer peripheral edge of the upper end of the hopper 4 is
It is fixed to the bottom of the car and attached to the sink. Note that a faucet 14 is arranged above the sink 12.

A motor 1 whose rotation is controlled by a control unit (control unit) 16 is provided below the crushing chamber 9 so as to be surrounded by the bracket 2 fixed to the hopper 4. A shaft 5 extending upward from the motor 1 projects at the lower center of the crushing chamber 9. A rotating plate 6 is fixed to the shaft 5, and a plurality of rotating blades 7, 8 are attached to the outer periphery of the rotating plate 6 so as to face the crushing chamber 9.
The fixed blade 3 is mounted in an annular shape outside the rotary blades 7 and 8 at the upper end of the bracket 2 so as to face the rotary blades 7 and 8. The rotary blades 7 and 8 may be hammers.

Thus, the garbage introduced into the crushing chamber 9 from the inlet 10 is crushed by the rotary blades 7 and 8 and the fixed blade 3.

Between the crushing chamber 9 and the motor 1, a crushing chamber 9 is provided.
A crushed material inflow chamber 15 into which a mixture of crushed garbage and water flows is formed. This pulverized material inflow chamber 15
Is connected to the crushing chamber 9 by a circulation path 17.

The pulverized material inflow chamber 15 has an outlet 13 for discharging the pulverized kitchen waste. The drain 13 is provided with a drain 18. And
The drainage channel 18 is provided with a valve (valve member) 19 for opening and closing the channel. The valve 19 is in the closed position during the grinding of the garbage, and is in the open position otherwise.

Here, the drainage channel 18 is formed tangentially to the wall surface of the pulverized material inflow chamber 15, and the circulation path 17 extends in the direction opposite to the drainage channel 18 so as to extend.
Are formed in the tangential direction of the wall surface of the.

The control device 16 controls the direction and number of rotations of the motor 1 and the opening and closing of the valve 19.

Next, the operation of the pulverizing apparatus having such a structure will be described. When the garbage is not crushed, the valve 19 installed in the drainage channel 18 is open. For this reason, when the sink 12 is used for washing dishes or the like, the wastewater is smoothly discharged from the discharge port 13 through the crushing device.

When the garbage is crushed,
The lid 11 is opened, and the garbage is charged from the charging port 10 and stored in the crushing chamber 9 in the hopper 4.

Next, the lid 11 is attached to the input port 10, the faucet of the faucet 14 is opened, and water flows. At the same time, the motor 1 is started to rotate the rotary plate 6, and at the same time, the valve 19 is closed and the drainage channel 18 is closed.

The operation of the valve 19 may be performed through the control device 16. If the motor 1 and the valve 19 are connected in parallel, the valve 19 closes at the same time as the motor 1 starts,
The valve 19 is opened at the same time when the motor 1 is stopped.

The rotary blades 7, 8 attached to the rotary plate 6 rotated by the drive of the motor 1 rotate in the circumferential direction of the rotary plate 6 with their cutting edges directed toward the fixed blade 3. Then, the put garbage is pressed toward the fixed blade 3 by centrifugal force due to the rotational movement of the rotary plate 6 and the rotary blades 7 and 8. Then, it is sheared by the action of the rotating blades 7 and 8 and the fixed blade 3 and is finely pulverized, and is pulverized formed under the pulverizing chamber 9 with water while rotating by the frictional action of the rotating plate 6 and the rotating blades 7 and 8. It is transferred to the material inflow chamber 15.

At this time, since the drainage passage 18 is closed by the valve 19, the mixture of the crushed garbage and water passes through the circulation passage 17 by the turning and pressurizing action of the rotating plate 6 and the rotating blades 7, 8. And returned to the crushing chamber 9. Then, the pulverized material is pulverized again in the pulverizing chamber 9 and transferred to the pulverized material inflow chamber 15 again.

As described above, the thrown garbage is supplied to the crushing chamber 9.
And is transferred to the pulverized material inflow chamber 15,
The water is circulated again along with the water through the path returned to the crushing chamber 9 through the process, and all of the crushed material is fine.

As described above, since the drainage channel 18 is closed by the valve 19 during the crushing of the garbage, the crushing chamber 9 is closed.
The water inside is not discharged outside. As a result, the garbage is crushed in a state where the fixed blade 3 and the rotary blades 7 and 8 are submerged, so that air is not entrained, so that the crushing noise is shielded and the crushing noise is reduced. Becomes possible.

The water and the garbage crushed in the crushing chamber 9 are:
The frictional action of the rotary plate 6 and the formation of the swirling flow by the rotary blades 7, 8 allow the pulverized material to return from the inflow chamber 15 to the pulverization chamber 9 through the circulation path 17, so that the fixed blade 3 and the rotary blade 7 , 8 do not require a large amount of water to submerge. Therefore, it is possible to reduce noise when the garbage is crushed with a small amount of water supply.

If the water in the pulverized material inflow chamber 15 is sufficiently accumulated and the water level reaches the positions of the rotary plate 6 and the rotary blades 7 and 8, a sufficient circulation amount can be obtained.
If it does not accumulate sufficiently, the swirling flow by the rotating plate 6 and the rotating blades 7 and 8 will not be sufficiently generated, and the circulation amount will be small.

When the grinding is completed, the motor 1 is stopped, the valve 19 is opened by the control device 16, and the drainage channel 18 is opened. Thereby, the mixture of the crushed kitchen waste and water is drained to the outside from the outlet 13 through the drainage channel 18. At this time, when the motor 1 is rotated (regardless of the rotation direction), the discharge becomes stronger, so that clogging in the middle of the piping is also prevented.

The mixture of the garbage and water after crushing that has flowed into the crushed material inflow chamber 15 has a swirling flow in the same direction as the rotation of the rotating plate 6. Therefore, the drainage channel 18 and the circulation channel 17 are formed in tangential directions extending in mutually opposite directions from the pulverized material inflow chamber 15, and the swirling flow during the pulverization toward the circulation channel 17 as shown in FIG. If rotated in the direction D <b> 1, the mixture of the crushed garbage and water is returned to the crushing chamber 9 through the circulation path 17 without attaching the valve 19 to the drainage path 18. In this case, after the pulverization, the control device 16 rotates the motor 1 in the reverse direction to reverse the rotation direction of the swirling flow in the second direction D2 opposite to the first direction D1. The mixture of water and water is drained from the outlet 13 to the outside through the drainage channel 18.

In this specification, the tangential direction is
The direction is not limited to a direction based on a tangent in a strict sense defined mathematically, but includes a direction close to this, that is, a substantially tangential direction.

Further, in order to return the mixture of garbage and water crushed in the crushed material inflow chamber 15 from the circulation path 17 to the crushing chamber 9, the motor 1 needs to have a rotation speed (circulation rotation speed) higher than a predetermined level. It is. Therefore, if the rotating direction is directed to the first direction D1 and the motor 1 is rotated at the circulation speed or more during the pulverization, the mixture of the pulverized kitchen garbage and water can be obtained without attaching the valve 19 to the drainage channel 18. It is returned to the crushing chamber 9 through the circulation path 17. In this case, if the rotation speed of the motor 1 is set to be equal to or lower than the circulation rotation speed after the pulverization, the mixture of the pulverized kitchen garbage and water is drained to the outside from the discharge port 13 through the drain passage 18.

As described above, the circulation and discharge of the mixture can be controlled by selecting the turning direction (D1 direction) and controlling the number of revolutions of the motor 1 by the control device 16.

If the direction of the swirling flow is switched or the swirling direction is selected (direction D1) and the flow rate of the pulverized material is controlled by the rotation speed of the motor 1, the valve 19 of the drainage channel 18 can be operated. Since it becomes unnecessary, space saving and cost reduction of the device can be achieved.

Here, as shown in FIG. 3, if the blades 20 are attached to the shaft 5 so as to be located in the pulverized material inflow chamber 15, the mixture flowing into the pulverized material inflow chamber 15 is forcibly forced by the blades 20. As they are rotated, these mixtures are more strongly returned from the circuit 17 to the grinding chamber 9.

Even if water is not sufficiently accumulated in the pulverized material inflow chamber 15, the mixture is returned from the circulation path 17 to the pulverized chamber 9 by the rotation of the blade body 20.

(Embodiment 2) FIG. 4 is a sectional view showing a pulverizing apparatus according to Embodiment 2 of the present invention.

As shown in the figure, the crushing device of the present embodiment is the same as the crushing device of FIG. 3 described in the first embodiment, except that the circulation path 17 is provided extending from the drainage channel 18. At the junction 21 between the circulation path 17 and the drainage path 18, a path extending from the discharge port 13 is provided.
A three-way valve (valve member) 22 that switches between a first path that returns to the crushing chamber 9 through the second path and a second path that extends from the drainage path 18 to the outside is provided.

Incidentally, such a structure can also be applied to the pulverizing apparatus shown in FIG. 1 described in the first embodiment.

Next, the operation of the pulverizing apparatus shown in FIG. 4 will be described. When the kitchen waste is not crushed, the valve position of the three-way valve 22 is set to a position where the second path is established. For this reason, when the sink 12 is used for washing dishes or the like, the drainage is smoothly discharged through the discharge port 13 and the drainage passage 18 through the pulverization processing device.

When the garbage is crushed,
The lid 11 is opened, and the garbage is charged from the charging port 10 and stored in the crushing chamber 9 in the hopper 4.

Next, the lid 11 is attached to the input port 10, the faucet of the faucet 14 is opened, and water flows. At the same time, the motor 1 is started to rotate the rotary plate 6, and at the same time, the valve position of the three-way valve 22 is set to a position where the first path is established.

The operation of the three-way valve 22 may be performed through the control device 16. Further, if the motor 1 and the three-way valve 22 are connected in parallel, the three-way valve 22 closes when the motor 1 starts, and the three-way valve 22 opens when the motor 1 stops.

The rotary blades 7, 8 attached to the rotary plate 6 rotated by the drive of the motor 1 rotate in the circumferential direction of the rotary plate 6 with their blades directed toward the fixed blade 3. Then, the put garbage is pressed toward the fixed blade 3 by centrifugal force due to the rotational movement of the rotary plate 6 and the rotary blades 7 and 8. Then, it is sheared by the action of the rotary blades 7 and 8 and the fixed blade 3 and finely pulverized, and has the frictional action of the rotary plate 6 and the swirling flow given by the rotary blades 7 and 8, and the water in the pulverizing chamber 9 together with water. It is transferred to the pulverized material inflow chamber 15 formed below.

In the pulverized material inflow chamber 15, the mixture of water and the pulverized garbage is further given kinetic energy by the blade body 20 driven by the motor 1. At this time,
Since the path extending from the discharge port 13 is the first path by the three-way valve 22, the mixture of the crushed garbage and water is returned to the crushing chamber 9 through the circulation path 17. Further, even when the water is not sufficiently accumulated in the pulverized material inflow chamber 15, the mixture is returned from the circulation path 17 to the pulverized chamber 9 by the rotation of the blade body 20.

Then, it is pulverized again in the pulverizing chamber 9 and transferred to the pulverized material inflow chamber 15 again. Even if the blade body 20 is not provided, if the number of rotations is increased, the mixture of water and kitchen waste is sufficiently returned to the crushing chamber 9 by the kinetic energy given to the rotary blades 7 and 8 and the rotary plate 6. .

When the water in the pulverized material inflow chamber 15 is sufficiently accumulated and the water level reaches the positions of the rotary plate 6 and the rotary blades 7, 8, a sufficient circulation amount can be obtained.
If it does not accumulate sufficiently, the swirling flow by the rotating plate 6 and the rotating blades 7 and 8 will not be sufficiently generated, and the circulation amount will be small.

The kitchen waste thus put into the crushing chamber 9
And is transferred to the pulverized material inflow chamber 15,
The water is circulated again along with the water through the path returned to the crushing chamber 9 through the process, and all of the crushed material is fine.

As described above, during the crushing of the garbage, the first path is selected by the three-way valve 22 and the flow path from the drainage channel 18 to the outside is closed. No water is discharged to the outside. As a result, the garbage is crushed in a state where the fixed blade 3 and the rotary blades 7 and 8 are submerged, so that air is not entrained, so that the crushing noise is shielded and the crushing noise is reduced. Becomes possible.

The water and the garbage crushed in the crushing chamber 9 are:
From the pulverized material inflow chamber 15 through the circulation path 17,
Therefore, a large amount of water is not required for submerging the fixed blade 3 and the rotary blades 7 and 8 in water. Therefore, it is possible to reduce noise when the garbage is crushed with a small amount of water supply.

Further, as described above, the circulation path 17 is connected to the drainage path 1.
8, the three-way valve 22 switches between the first path and the second path, so that the crushed garbage can be reliably circulated and discharged.

When the pulverization is completed, the motor 1 is stopped, the valve position of the three-way valve 22 is switched, and the second path is selected. As a result, the flow path from the drainage channel 18 to the outside is opened, and the mixture of the crushed kitchen waste and water is drained to the outside from the discharge port 13 through the drainage channel 18. At this time, if the motor 1 is rotated again (regardless of the rotating direction), the discharge becomes stronger, so that clogging in the middle of the piping is also prevented.

The three-way valve 22 is located at the junction 21 in this way.
Without providing a valve, a valve may be attached to both or one of the drainage channel 18 and the circulation channel 17 to switch between the circulation between the pulverized material inflow chamber 15 and the pulverization chamber 9 and the discharge from the discharge port 13. . That is, in the present invention, the path extending from the discharge port 13 by some valve member is changed to the first path returning to the crushing chamber 9 through the circulation path 17 and the drain path 18.
It is only necessary to be able to switch to any one of the second path from to the outside.

(Embodiment 3) FIG. 5 is a sectional view showing a pulverizing apparatus according to Embodiment 3 of the present invention.

As shown in the figure, the crushing apparatus of the present embodiment differs from the crushing apparatus of FIG. 1 described in the first embodiment in that the mixture of crushed garbage and water in the crushed material inflow chamber 15 is forcibly removed. A pump (transporting means) 23 for feeding the powder to the crushing chamber 9 is attached to the circulation path 17.

Note that such a structure can be applied to the pulverizing apparatus shown in FIG. 1 described in the first embodiment.

Next, the operation of the pulverizing apparatus having such a structure will be described. When the garbage is not crushed, the valve 19 installed in the drainage channel 18 is open. For this reason, when the sink 12 is used for washing dishes or the like, the wastewater is smoothly discharged from the discharge port 13 through the crushing device.

When the garbage is crushed,
The lid 11 is opened, and the garbage is charged from the charging port 10 and stored in the crushing chamber 9 in the hopper 4.

Next, the lid 11 is attached to the input port 10, the faucet of the faucet 14 is opened, and water flows. At the same time, the motor 1 is started to rotate the rotary plate 6, and at the same time, the valve 19 is closed and the drainage channel 18 is closed.

The operation of the valve 19 may be performed through the control device 16. If the motor 1 and the valve 19 are connected in parallel, the valve 19 closes at the same time as the motor 1 starts,
The valve 19 is opened at the same time when the motor 1 is stopped.

The rotary blades 7 and 8 attached to the rotary plate 6 rotated by the drive of the motor 1 rotate in the circumferential direction of the rotary plate 6 with their blades directed toward the fixed blade 3. Then, the put garbage is pressed toward the fixed blade 3 by centrifugal force due to the rotational movement of the rotary plate 6 and the rotary blades 7 and 8. Then, they are sheared by the action of the rotary blades 7 and 8 and the fixed blade 3, finely pulverized, and formed under the pulverizing chamber 9 together with water at a flow rate given by the rotary plate 6 and the rotary blades 7 and 8. The crushed material is transferred to the inflow chamber 15.

At this time, the drainage passage 18 is closed by the valve 19, and in addition to the pressurizing action of the rotary plate 6 and the rotary blades 7, 8, the mixture of the crushed garbage and water is circulated by driving the pump 23. It is forcibly returned from the passage 17 to the grinding chamber 9. And
The pulverized material is pulverized again in the pulverizing chamber 9 and transferred to the pulverized material inflow chamber 15 again.

The drive timing of the pump 23 is determined by connecting the pump 23 and the motor 1 in parallel, or simultaneously with the start of the motor 1 by the control device 16, or from the start of the motor 1 by the control device 16 using a timer or the like. It may be delayed. Furthermore, a sensor (not shown) detects that a mixture of crushed garbage and water has accumulated in the crushed material inflow chamber 15 and the circulation path 17, and the control device 16 receives the detected water and starts the operation. Is also good.

[0086] The kitchen waste thus put into the crushing chamber 9
And is transferred to the pulverized material inflow chamber 15 by the pump 23.
Thus, the water is circulated together with water on the path returned to the grinding chamber 9 through the circulation path 17 again, and all become fine pulverized materials.

Here, during the crushing of the garbage, the drainage
Is closed by the valve 19, so that the fixed blade 3 and the rotary blades 7, 8
The garbage will be crushed in a state where is submerged. Therefore, since air is not entrained, the crushing noise is shielded, and it is possible to realize a quieter crushing.

Further, the water and the garbage crushed in the crushing chamber 9 are:
Since the pulverized material inflow chamber 15 is returned to the pulverization chamber 9 through the circulation path 17 by the pump 23 again,
A large amount of water is not required to submerge the fixed blade 3 and the rotary blades 7 and 8 in water. Therefore, it is possible to reduce noise when the garbage is crushed with a small amount of water supply.

When the pulverization is completed, the motor 1 is stopped, the valve 19 is opened through the control device 16, and the drainage channel 18 is opened. If the motor 1 and the valve 19 are connected in parallel and the motor 1 is manually stopped, even if the control device 16 is not provided,
At the same time, the valve 19 can be closed.

Thus, the mixture of the crushed garbage and water is drained from the outlet 13 to the outside through the drain 18. At this time, if the motor 1 is rotated again (regardless of the rotating direction), the discharge becomes stronger, so that clogging in the middle of the piping is also prevented.

As described above, by transferring the mixture from the pulverized material inflow chamber 15 to the pulverization chamber 9 by the pump 23, it is possible to reliably perform the circulating process of the pulverized kitchen waste.

(Embodiment 4) FIG. 6 is a sectional view showing a pulverizing apparatus according to Embodiment 4 of the present invention.

As shown in the figure, the pulverization processing apparatus of the present embodiment is different from the pulverization processing apparatus of FIG. A pump (transporting means) 23 for feeding the powder to the crushing chamber 9 is attached to the circulation path 17. However, unlike FIG. 4, the blade 20 is not provided in FIG. 6, but the blade 20 may be provided.

Next, the operation of the pulverizing apparatus shown in FIG. 6 will be described. When the kitchen waste is not crushed, the valve position of the three-way valve 22 is set to a position where the second path is established. For this reason, when the sink 12 is used for washing dishes or the like, the drainage is smoothly discharged through the discharge port 13 and the drainage passage 18 through the pulverization processing device.

When the garbage is crushed,
The lid 11 is opened, and the garbage is charged from the charging port 10 and stored in the crushing chamber 9 in the hopper 4.

Next, the lid 11 is attached to the input port 10, the faucet of the faucet 14 is opened, and water is allowed to flow. At the same time, the motor 1 is started to rotate the rotary plate 6, and at the same time, the valve position of the three-way valve 22 is set to a position where the first path is established.

The operation of the three-way valve 22 may be performed through the control device 16. Further, if the motor 1 and the three-way valve 22 are connected in parallel, the three-way valve 22 closes when the motor 1 starts, and the three-way valve 22 opens when the motor 1 stops.

The rotary blades 7 and 8 attached to the rotary plate 6 which is rotated by the drive of the motor 1 rotate in the circumferential direction of the rotary plate 6 with the cutting edges directed to the fixed blade 3. Then, the put garbage is pressed toward the fixed blade 3 by centrifugal force due to the rotational movement of the rotary plate 6 and the rotary blades 7 and 8. Then, it is sheared by the action of the rotating blades 7 and 8 and the fixed blade 3 and is finely pulverized, and is pulverized formed under the pulverizing chamber 9 with water while rotating by the frictional action of the rotating plate 6 and the rotating blades 7 and 8. It is transferred to the material inflow chamber 15.

At this time, since the path extending from the discharge port 13 is the first path by the three-way valve 22, the mixture of the pulverized garbage and water is
It is returned to the grinding chamber 9 through 7. Then, the pulverized material is pulverized again in the pulverizing chamber 9 and transferred to the pulverized material inflow chamber 15 again.

The drive timing of the pump 23 is determined by connecting the pump 23 and the motor 1 in parallel, or simultaneously with the start of the motor 1 by the control device 16, or from the start of the motor 1 by the control device 16 using a timer or the like. It may be delayed. Furthermore, a sensor (not shown) detects that a mixture of crushed garbage and water has accumulated in the crushed material inflow chamber 15 and the circulation path 17, and the control device 16 receives the detected water and starts the operation. Is also good.

[0096] In this way, the kitchen waste put into the crushing chamber 9
And is transferred to the pulverized material inflow chamber 15 by the pump 23.
Thus, the water is circulated along the path returned from the circulation path 17 to the crushing chamber 9 again with water, and all of the crushed material becomes fine crushed material.

As described above, during the crushing of the garbage, the first path is selected by the three-way valve 22 and the flow path from the drainage path 18 to the outside is closed. The crushing of the garbage is performed in a state where the rotary blades 7 and 8 are submerged, so that the crushing sound is shielded, and it is possible to realize a quieter crushing.

[0098] The water and the garbage crushed in the crushing chamber 9 are:
From the pulverized material inflow chamber 15 through the circulation path 17,
So that a large amount of water is not required to submerge the fixed blade 3 and the rotary blades 7 and 8, making it possible to reduce noise when grinding garbage with a small amount of water supply. Become.

When the grinding is completed, the motor 1 is stopped, the valve position of the three-way valve 22 is switched, and the second path is selected. As a result, the flow path from the drainage channel 18 to the outside is opened, and the mixture of the crushed kitchen waste and water is drained to the outside from the discharge port 13 through the drainage channel 18. At this time, if the motor 1 is rotated again (regardless of the rotating direction), the discharge becomes stronger, so that clogging in the middle of the piping is also prevented.

As described above, also in the present embodiment, the transfer of the mixture from the pulverized material inflow chamber 15 to the pulverization chamber 9 by the pump 23 enables the circulation processing of the pulverized garbage to be reliably performed.

In the above description, kitchen waste such as vegetable waste and fish bones is shown as a processed material. However, the present invention is not limited to such kitchen waste, and various other pulverizable materials can be used. Things can be applied.

[0102]

As described above, according to the present invention, since the water in the crushing chamber is not discharged to the outside during the crushing of the garbage, the crushed material is crushed in a state where the fixed blade and the rotary blade are submerged. Is performed, and the crushing noise is shielded, so that it is possible to achieve an effective effect that it is possible to realize a silent operation during the crushing.

Further, according to the present invention, the treated material pulverized in the pulverizing chamber is returned to the pulverizing chamber together with water from the pulverized material inflow chamber through the circulation path. A large amount of water for submerging is not required, and an effective effect is obtained in that it is possible to reduce noise when pulverizing the processed material with a small amount of water supply.

If the direction of the swirling flow of the processed material to be pulverized is switched, and the flow of the pulverized material is controlled by selecting the swirling direction and the number of rotations of the motor, the valve member of the drainage channel becomes unnecessary, and the apparatus becomes unnecessary. An effective effect is obtained that it is possible to save space and reduce costs.

If the blades are installed in the pulverized material inflow chamber,
Since the processed material and the water that have flowed into the pulverized material inflow chamber are forcibly rotated by the blades, an effective effect that the processed material can be more strongly returned from the circulation path to the pulverizing chamber can be obtained.

By providing a circulation path extending from the drain path and switching between the first path and the second path by a valve member, the circulation processing and the discharge processing of the pulverized processed material can be reliably performed. The effective effect that it becomes possible is obtained.

By attaching the conveying means to the circulation path, there is obtained an effective effect that it is possible to reliably carry out the circulation processing of the pulverized processed material from the pulverized material inflow chamber to the pulverization chamber.
