[0036]
In the present embodiment, the processing chamber 7 and the case 4 configured as described above are integrally provided.
[0037]
Next, garbage processing by the garbage processing apparatus configured as described above will be described.
[0038]
Garbage from the home or the like is put together with water into the inlet 11 of the sink 1 of the kitchen. Garbage thrown into the inlet 11 is pulverized by the disposer 2 and then introduced into the dewatering screen 3 from the inlet 31 of the dewatering screen 3 through the communication passage 22 together with the water. It is conveyed upward along the upper surface of the screw part 52 of the conveying screw 5.
[0039]
Thereby, the ground garbage is dehydrated by separating water from the dewatering holes 32 to the outside of the dewatering screen 3 according to the upward conveyance, and the discharge port 33, the rising wall 34, 35, and discharged to the processing chamber 7 through the chute 71.
[0040]
At this time, since the rising wall 35 is urged toward the closing position by the coil spring 37, the crushed garbage pushed out from the upper end of the dewatering screen 3 to the discharge port 33 is applied to the rising wall 35 by the crushed garbage. When the applied pressing force exceeds a predetermined force that is greater than the urging force of the coil spring 37, the rising wall 35 is swung toward the open position against the urging force of the coil spring 37 through the chute 71. Then, it is discharged into the processing chamber 7.
[0041]
In this way, the crushed garbage is discharged to the chute 71 while restricting the discharge by the rising wall 35 on the discharge port 33 side. The compression force of the crushed garbage can be increased by the amount of discharge restriction. Thereby, the pulverized raw garbage can be sufficiently dehydrated, and a decomposition process in the processing chamber 7 described later can be effectively performed.
[0042]
The discharge port 33 is closed by the rising wall 35 when there is no pulverized garbage, and when there is crushed garbage, the pulverized garbage is urged by the rising wall 35 biased to the closed position side. It is in a state of being blocked by. For this reason, even if the water introduced into the dewatering screen 3 together with the crushed garbage reaches the discharge port 33 at once, this water can be blocked by the rising wall 35 and the pulverized garbage at the discharge port 33. . Accordingly, it is possible to prevent water from entering the processing chamber 7 through the discharge port 33, and to prevent degradation of the decomposition processing capacity due to water intrusion into the processing chamber 7, thereby performing the treatment in combination with the above-described dehydrating action. The decomposition treatment in the chamber 7 can be performed while maintaining high efficiency.
[0043]
On the other hand, the water discharged from the dewatering hole 32 to the outside of the dewatering screen 3 is drained from the drainage port 41 to the outside of the case 4 through the drainage pipe 42.
[0044]
Further, the dewatered crushed garbage discharged into the processing chamber 7 described above is suitably stirred with the moisture adjusting agent by the stirring member 73 in the processing tank 72, whereby the moisture is absorbed by the moisture adjusting agent. Thus, the fermentation is promoted by the heating by the heater 76 and the supply of air into the processing chamber 7 from the air supply port while the moisture amount is adjusted, and the corrosion decomposition process is rapidly performed. As a result, the crushed garbage is reduced in the processing tank 72 of the processing chamber 7.
[0045]
In the above-described decomposition treatment process, odor and moisture generated in the processing chamber 7 are introduced from the exhaust port 81 into the space 43 in the case 4 through the exhaust pipe 82, and discharged from the drain port 41 through the drain pipe 42 together with the drainage. Exhausted.
[0046]
At this time, since the moisture adjusting agent is also dried and the moisture absorbed from the pulverized garbage is exhausted to the outside through the exhaust pipe 82, the moisture of the newly added pulverized garbage can be absorbed again by this moisture adjusting agent. It becomes a state. That is, since the moisture adjusting agent stored in the treatment tank 72 can be used repeatedly for a long time and it is not necessary to replenish the moisture adjusting agent frequently, the operating cost can be greatly reduced.
[0047]
Due to the decomposition processing of the crushed garbage in the processing chamber 7, the processed product is gradually stored in the processing tank 72, and when the processed product becomes full in the processing tank 72, the full sensor detects this. To detect. If there is this detection, the operation is stopped, the processed material in the processing tank 72 is taken out of the processing chamber 7 through an opening / closing door (not shown), and a predetermined amount of moisture adjusting agent is newly introduced into the processing tank 72. Subsequently, the ground garbage is decomposed as described above.
[0048]
In the present embodiment, the opening / closing means that opens and closes the discharge port 33 by swinging the rising wall 35 in the horizontal direction has been described. However, the opening / closing means is not limited to this, and for example, vertical swinging. The outlet 33 may be opened and closed by the above. Further, not only the rising wall 35 but also a structure in which the left and right rising walls 34 and 35 are swung, or a structure in which one or both of the rising walls 34 and 35 are swung is used. Good.
[0049]
【The invention's effect】
As described above, according to the garbage processing apparatus of the present invention, the opening / closing means for opening the discharge port from the closed state when pressed with a predetermined force by the pulverized garbage pushed from the dehydrating screen side to the discharge port. By providing it, it is possible to improve the dewatering capacity of pulverized garbage in the dewatering screen, and it is possible to prevent sudden discharge of water etc. from the discharge port, and to improve the processing of pulverized garbage It can be performed efficiently while maintaining.
