BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage crushing apparatus for crushing hydrated garbage discharged from a commercial kitchen or a general household kitchen and separating the garbage into solid and liquid.

[0002]

2. Description of the Related Art As this kind of garbage crushing apparatus,
There is one described in Japanese Patent Application No. 5-083676 (JP-A-6-292996) previously proposed by the applicant. FIG.
This garbage crushing apparatus is shown in a schematic sectional view in FIG.
This garbage crushing apparatus includes a crushing section A for crushing hydrated garbage and a solid-liquid separation section B for cutting off hydrated garbage crushed in the crushing section A.

[0003] The crushing section A is a section into which hydrated garbage discharged through a drain port of a kitchen, a kitchen or the like is introduced, and is finely crushed and discharged in a crushing chamber inside the garbage.

[0004] The solid-liquid separation section B is generally configured as follows. That is, the solid-liquid separation section B has a rotary screw 2 provided inside a cylindrical screen 1 and a cylindrical outer case 3 outside the screen 1.
Has been deployed. Further, an introduction space 4 for the water-containing garbage finely crushed in the crushing section A is provided at the inner bottom of the screen 1, and an outlet 5 for dewatered garbage is opened at an upper portion of the screen 1. Further, a drain port (not shown) is provided in a water receiving space 6 formed between the screen 1 and the outer case 3. The rotary screw 2 is driven to rotate by a motor M. Reference numeral 7 denotes an entrance of the water-containing garbage into the introduction space 4.
The outlet of the pulverizing section A is connected via a hose 8 or the like. The extrusion opening 5 is formed by an annular opening formed between the upper end of the screen 1 and the plug 9 mounted on the upper end of the shaft 2a of the rotary screw 2. Reference numeral 10 denotes a blade provided on the upper portion of the plug 9, which plays a role of discharging garbage extruded from the extrusion port 5 from the chute 11 to the storage box 12.

The following processing is performed in the solid-liquid separation section B. The water-containing garbage that has been pulverized and introduced into the introduction space 4 is rotated by the rotation screw 2 so that the screen 1
Is transported upward as indicated by an arrow a, and water separated from the water-containing garbage during the transport passes through a number of water holes (not shown) formed in the screen 1 to the receiving space 6. On the other hand, the garbage after dewatering is pushed out from the extrusion port 5 and then discharged to the storage box 12 via the chute 11. The water flowing into the receiving space 4 is discharged through the drain port provided at the lower end of the outer case 3.

In such a garbage crushing apparatus,
The wet garbage conveyed upward from the introduction space 4 through the inside of the screen 1 by the action of the rotary screw 2
It needs to be compressed appropriately while approaching the extrusion port 5.
That is, if the degree of compression during conveyance is too large, the load on the motor M for driving the rotary screw 2 will be too large, causing problems such as seizure. Conversely, if the degree of compression is too small, water-containing garbage will not be sufficiently removed. Can not be dehydrated.

[0007]

There is a wide variety of garbage discharged from kitchens and kitchens, and an appropriate degree of compression when dewatering in the solid-liquid separation section B after the pulverization process differs depending on the type of garbage. However, in the above-described conventional garbage crushing apparatus, the extrusion port 5 formed by an annular opening formed between the upper end of the screen 1 and the plug 9 is used.
Is fixed, and the user cannot perform an operation of freely changing the opening area as needed. For this reason, the garbage discharged after the water cutoff process still contains a lot of water, and the garbage is not smoothly transported upward by the rotary screw 2 in many cases.

[0008] The present invention has been made in view of the above circumstances, and by making it possible to freely increase or decrease the opening area of the extrusion port according to the type of water-containing garbage, dewatering of garbage. It is an object of the present invention to provide a garbage crushing apparatus capable of smoothly and appropriately performing the garbage crushing.

[0009]

SUMMARY OF THE INVENTION The present invention comprises a crushing section for hydrated garbage and a solid-liquid separating section for crushing hydrated garbage in the crushing section. A cylindrical body forming an aquatic garbage introduction space; a cylindrical screen communicated with the introduction space and arranged above the cylinder and having a water hole formed in a peripheral wall; A rotary screw for transporting the water-containing garbage that has been fed to the introduction space upwardly, and receiving water that is provided outside the screen and separated from the water-containing garbage and that has flowed out through the water holes of the screen. A cylindrical outer case forming a space, a drain port provided in the outer case for discharging water flowing into the receiving space, and a dewatering garbage extrusion port opened at an upper portion of the screen. Garbage crusher An apparatus, wherein the extrusion port is formed in an annular shape by an opening between an upper end of the screen and a shaft provided at an upper end of the rotating screw, and the dewatered raw material extruded from the extrusion port. A pressure receiving plate pushed upward by dust is disposed over the extrusion port, and an annular plug whose diameter increases toward the upper side is fixed to the pressure receiving plate downward, and the plug is connected to the rotary screw. A shaft body having a male screw is inserted through the insertion hole formed in the pressure receiving plate so as to be able to move up and down with the shaft portion so as to be able to move up and down with respect to the extrusion port, and to be inserted into the pressure receiving plate. The male screw of the body is screwed into a female screw of a screw hole provided in the shaft of the rotary screw so as to be freely rotatable forward and backward, and the upper end of the shaft hits the pressure receiving plate to prevent upward movement of the pressure receiving plate. The stopper is provided, is that.

In the present invention, the water-containing raw garbage conveyed upward from the introduction space through the inside of the screen by the action of the rotary screw approaches the extrusion port while being compressed at a compression degree corresponding to the opening area of the extrusion port. The water separated from the water-containing garbage during the transportation passes through the screen, flows into the water receiving space, and is discharged from the drain of the outer case. The garbage after dehydration is pushed out from the extrusion port. And the garbage pushed out from the extrusion port hits the pressure receiving plate and pushes the pressure receiving plate upward,
The pressure receiving plate moves up to a position where it hits the stopper to open the extrusion port.

In the garbage crushing apparatus of the present invention,
The degree of compression of the garbage being conveyed is determined by the size of the opening area of the extrusion port and the amount of garbage extruded from the extrusion port, and the amount of the garbage extruded from the extrusion port is determined. It is mainly determined by the size of the quantity.
Therefore, when it is necessary to increase the degree of compression according to the type of water-containing garbage, the male screw of the screw shaft is screwed into the female screw of the shaft of the rotary screw to increase the amount of projection of the plug into the extrusion port, and the stopper Lower the position of. By doing so, the opening area of the extrusion port is reduced, and the degree of compression is increased. Conversely, when it is necessary to reduce the degree of compression according to the type of water-containing garbage, reduce the amount of protrusion of the plug into the extrusion port by screwing the male screw of the screw shaft from the female screw of the shaft of the rotating screw. At the same time, raise the position of the stopper. If it does so, the opening area of an extrusion opening will expand and the degree of compression will fall. In these cases, the pressure receiving plate is pushed upward by the garbage pushed out from the extrusion port, so that the pressure receiving plate moves up to a position where it hits the stopper to open the extrusion port. When the vertical position of the pressure receiving plate regulated by the stopper is changed, the force of the garbage pushed out from the extrusion port to push the pressure receiving plate upward changes. It is also possible to adjust the degree of compression.

In the present invention, a disc-shaped receiving plate for receiving dewatered garbage extruded from the extruding port is provided around the extruding port, and a peripheral wall is raised around the outer periphery of the receiving plate. In addition, a part of the peripheral wall is cut off, and a chute is provided in the cutout portion to be connected to the receiving plate to discharge garbage, and the pressure receiving plate radiates from the rotation center of the pressure receiving plate. It is possible to adopt a configuration in which a blade plate extending in the direction is protruded toward the receiving plate.

With this configuration, the garbage extruded from the extrusion port is efficiently discharged to the chute by the blades rotating together with the rotary screw.

In the present invention, a spring body is provided between the pressure receiving plate and an upper end portion of the rotary screw to constantly urge the pressure receiving plate upward and abut against the stopper. It is desirable to adopt the configuration described above.
With this configuration, even when the operation of the processing apparatus is stopped, that is, even when the garbage is not pushed out from the extrusion port, the pressure receiving plate is raised to the position where the pressure receiving plate hits the stopper by the force of the spring body, and the extrusion port is Is open,
There is an advantage that the size of the open area of the extrusion port can be easily visually confirmed.
