Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a garbage supply device in a garbage processing facility that crushes garbage received from a hopper and supplies it to the next process.
[0002]
[Prior art]
A hopper is used as a facility for putting garbage into a composting device or the like, and a biaxial screw conveyor is used as a device for crushing and cutting the garbage received from the hopper.
In this biaxial screw conveyor, two screw conveyors are arranged in parallel with each other in a housing, and the two screw conveyors feed the waste to the outlet side while crushing the garbage by the rotation of each other.
[0003]
[Problems to be solved by the invention]
However, if garbage containing a lot of fiber or plastic waste in a plastic bag is put into a twin screw conveyor, the garbage is compressed and overloaded, and the screw conveyor trips and cannot be cut out. There was a fear. Also, round garbage such as radish, cabbage, etc. may be mixed and sent into garbage with a lot of moisture and oil, but if these garbage fall to the final biaxial crusher On the crushing shaft of the biaxial crusher, the round garbage is not bitten by the crushing teeth by sliding, and the rotation is repeated on the spot. As a result, there is a problem in that the garbage left without being crushed stays in that position and causes clogging of the crushed teeth, which makes it impossible to sufficiently treat the garbage.
[0004]
The present invention solves the above problems and provides a garbage supply device in a garbage processing facility that can efficiently cut even garbage with a lot of fiber and can reliably crush even round garbage. With the goal.

[0017]
The garbage transfer conveyor 8 is connected to a drain pipe 10 connected to a drain water tank 9 so that water collected in the housing 80 is collected in the drain water tank 9. The water accumulated in the drain water tank 9 is sent to the supply destination through the pump 11 through the pipe 12.
[0018]
The operation of the garbage disposal facility will be described.
For example, when garbage in a plastic bag is put into the hopper 1, the plastic bag is broken by the rotation of the bag breaking claws 32 and 33 of the bag breaking device 3. Thus, the garbage that has jumped out of the plastic bag falls into the housing 40 of the cutting device 4. The garbage that has fallen into the housing 40 is sent out to the forward direction outlet side by the rotation of the screw conveyor 41 of the cutting device 4.
At this time, when the plastic bag is caught on the bag breaking claws 32 and 33 of the bag breaking device 3 or the screw conveyor 41 of the cutting device 4, the bag breaking claws 32 and 33 of the bag breaking device 3 are driven in reverse rotation. Take out. Moreover, the screw conveyor 41 of the cutting device 4 is reversely driven to take out. When the screw conveyor 41 of the cutting device 4 is driven to rotate in the reverse direction, the screw conveyor 41 is fed in the direction opposite to the forward direction outlet side of the housing 40 and sent toward the discharge port 46. In this way, it can be taken out from the discharge port 46 for unsuitable items provided in the housing 40.
[0019]
Thus, the garbage in the housing 40 is fed to the outlet side in the forward direction while being crushed by the rotation of the screw conveyor 41 of the cutting device 4 and supplied to the conveyor 5 for conveyance. In the conveyor 5 for conveyance, it sends to the next process by the screw conveyor 51.
[0020]
On the outlet side of the screw conveyor 51 in the forward rotation direction, a discharge port 55 for the next process is provided in the housing 50, and garbage is fed into the housing 60 of the pusher 6 from the discharge port 55.
When a plastic bag or the like is entangled with the screw conveyor 51, the screw conveyor 51 is driven in reverse to be taken out from the discharge port 56 of the housing 50.
[0021]
The garbage sent to the pusher 6 is pressure-fed while being crushed by the rotation of the uniaxial screw conveyor 61 and is sequentially fed to the biaxial crushing device 7. At this time, garbage such as round cabbages is also reliably crushed by being pressed against the pair of crushing blades 71 and 72 of the biaxial crusher 7 by the uniaxial screw conveyor 61 of the pusher 6.
[0022]
The garbage completely crushed by the biaxial crusher 7 is transferred to the next process by the garbage transfer conveyor 8.
[0023]
As described above, according to the above-described embodiment, garbage containing a large amount of fiber, garbage put in a plastic bag, or the like is used as a cutting device 4 having a single screw conveyor 41, 51, 61, a conveyor for conveyance. 5. Since it is surely cut out sequentially by the pusher 6, it is possible to eliminate the problem that the raw garbage such as fiber that has been generated in the conventional biaxial screw conveyor is compressed and is overloaded.
[0024]
In addition, since the cutout device 4 and the conveyor 5 for transportation are provided with discharge ports 46 and 56 for inappropriate items, even when a plastic bag or the like is clogged, by driving the screw conveyors 41 and 51 in reverse, Easy to take out.
Furthermore, since the hopper 1 is provided with the bag breaking device 3, it is possible to break the plastic bag and supply only the internal garbage to the cutting device 4 side.
[0025]
In the front stage of the biaxial crushing device 7, a vertically placed pusher 6 provided with a uniaxial screw conveyor 61 is arranged, so that round cabbages and the like to which water or oil adheres have been sent without being crushed. Even in this case, since the uniaxial screw conveyor 61 is pressed against the crushing blades 71 and 72 of the biaxial crushing device 7, it can be reliably crushed without slipping.
[0026]
Further, the moisture contained in the garbage falls into the housing 80 when it is sent by the garbage transfer conveyor 8, and the moisture accumulated in the housing 80 can be accumulated in the drain water tank 9 through the drain pipe 10. Can remove water contained in garbage.
[0027]
The present invention is not limited only to the above embodiment. For example, the hopper used in the above embodiment is used when throwing garbage into the composting apparatus, and is also put into the methane fermentation apparatus. It can also be used when Moreover, in the said embodiment, although the 1st screw conveyor was comprised with the cutting device 4 and the conveyor 5 for conveyance, and the 2nd screw conveyor was comprised with the pushing machine 6, the cutting device 4 is pushed in directly. It can also be directly connected to the machine 6. In addition, it cannot be overemphasized that it can change suitably and implement within the range which does not change the gist of the present invention.
[0028]
