DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
In the garbage processing machine of Japanese Patent Publication No. 961), in order to remove water from the garbage and dry it, the garbage is heated to evaporate and separate the water. Since the removal of water is performed only by evaporation separation, a large amount of heating energy is required, and it takes a long time for drying. Therefore, the power consumption was large. Further, since the raw garbage is only stirred but not pulverized, it is difficult to remove water from the inside of the large garbage, and complete drying cannot be performed. The amount of garbage could not be significantly reduced because raw garbage was only dried and not powdered. Although the dried raw garbage is still dry, it remains in its original form and it is physiologically painful to remove it from the raw garbage container by hand.

In the present invention, the water content of raw garbage is crushed and dehydrated to remove water as mechanically as possible.
As a result, the removal of water by evaporation of water by heating is minimized, and the power consumption and the drying time are reduced.
Further, the treated raw garbage is made into a dry powder. Furthermore, it can be sucked from the garbage container and automatically stored in the garbage bag. In this way, since the garbage can be automatically stored in the storage bag, it is easy to dispose of the garbage. Since the garbage is dried powder, the amount of garbage can be greatly reduced. It is an object to provide such a garbage processing machine.

[0005]

In order to achieve the above object, in the garbage treating machine of the present invention, a rotary dehydrating tank 1 for storing and dehydrating the garbage and a bottom portion in the dehydrating tank are provided. A rotary crushing cutter 2 for crushing raw garbage, and a filter 4 provided in a dehydration hole 3 of a dehydration tank, for cleaning the filter outside the filter provided in the dehydration hole and for drying the raw garbage. An air nozzle 6 for ejecting air is provided. Further, a suction nozzle 38 for sucking dried powdery raw garbage and a raw garbage storage bag 35 for storing the sucked raw garbage are provided at the bottom of the dehydration tank.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described based on examples with reference to the drawings. In FIG. 1, a raw garbage processor 33 mainly includes a lid 13 and a rotary dehydration tank 1 for storing and dehydrating raw garbage, a crushing cutter 2 for crushing raw garbage, and a plurality of air nozzles for drying the raw garbage. It is composed of six. The dehydration tank 1 is composed of an inner cylinder 7 having a bottom, a filter 4 and an outer cylinder 8. Inner cylinder 7 and outer cylinder 8
A plurality of dehydration holes 3 and 5 are formed in the. The rotation drive of the dehydration tank is performed by the drive motor 19 and the speed reduction mechanism 20.
This drive motor and deceleration mechanism are shared with the rotation drive of the crushing cutter, and the rotation drive of the dehydration tank and the crushing cutter is switched by the switching device built into the reduction mechanism. The crushing cutter rotates with 2 or 3 blades to crush the dust finely. The air nozzle 6 is provided on the outer periphery and the bottom of the dehydration tank. This air nozzle blows air from the dehydration hole 5 into the dehydration tank, and sends air for cleaning the filter 4 and drying the dust after dehydration. The air nozzle is attached to a nozzle mounting tube 9 having a bottom. Reference numeral 10 is an air chamber for storing air to be supplied to the air nozzle, and 11 is a heater, which is a heat source for blowing hot air from the bottom into the dehydration tank. Reference numeral 21 is a drainage pipe for putting the drainage discharged from the dehydration tank and dropped into the nozzle mounting cylinder into the drainage tank 18. A drainage pump 22 is provided in the drainage tank, and the drainage pump 22 supplies the purified water filtered by the water purifier 23 to a water storage tank 24. This water tank is installed in a place that is easy to remove. The water in the water storage tank goes through a water purifier, so the smell of garbage is gone. Reference numeral 15 denotes an air tube packing, which is a packing for preventing the air ejected from the air nozzle from short-circuiting to the exhaust hole 16 and flowing out.
When the spin-drying tank rotates, it is not in close contact with the spin-drying tank as shown in the figure, but when the spin-drying tank is stopped and air is blown to dry the dust, air is put into the air tube packing to inflate the spin-drying tank. In close contact with. The air used to dry the garbage passes through the gap between the upper part of the dehydration tank and the lid and is discharged from the exhaust hole 16 to the donut-shaped exhaust duct 17.
The discharged air is compressed by the exhaust compressor 25 to become high-pressure air, passes through the dehumidifier 26, the deodorizer 27, and the electromagnetic valve 28, and is sent again from the air nozzle 6 into the dehydration tank. The air sent to the dewatering tank is dehumidified and deodorized by the dehumidifier and the deodorizer, so that it becomes dry and odorless air. The solenoid valve 28 can block the air to the air nozzle and adjust the flow rate. The solenoid valve 29 is a solenoid valve for inflating the air tube packing 15, and the solenoid valve 30 is a solenoid valve for letting out air for contracting the air tube packing. A packing 14 is provided on the lid 13 of the garbage processing machine to prevent the smell from the garbage processing machine from going out. The lid has a structure that is strongly pressed by a spring or the like, so that the lid does not open even when the pressure inside the garbage processing machine fluctuates. A pressure fluctuation prevention device such as an accumulator may be provided for pressure fluctuations. Further, the air circuit such as the compressor, the dehumidifier, and the deodorizer, and the drain circuit such as the drainage pump, the water purifier, and the water storage tank are stored in the closed container 32 provided in the garbage processing machine, and the odor is removed. I try not to go out.
The air circuit is a closed circuit, and is a circuit that circulates only inside the garbage processing machine so that the smell of the garbage does not go out.

Reference numeral 38 in FIG. 1 is a suction nozzle for sucking dry powdery garbage. This suction nozzle is shown in FIG.
As shown in FIG. 4, which is a detailed view of the part, it is provided on the lower surface of the boss of the crushing cutter 2. The powdery raw dust is sucked from this suction nozzle and discharged through the raw dust suction hole 39 formed in the crushing cutter drive shaft 37. 40 of FIG.
Is a garbage suction pipe communicating with the garbage suction hole 39. Reference numeral 41 is a rotary joint of the garbage suction pipe, and the garbage suction hole 3 formed in the rotating crushing cutter drive shaft 37.
9 is for connecting the fixed garbage suction pipe. The sucked raw garbage is stored in the raw garbage storage bag 35 which is a bag filter according to the same principle as that of the electric vacuum cleaner. Since this garbage bag is not shown in FIG. 1,
Please refer to FIG. 3 shown in another embodiment. Further, the suction nozzle 38 is designed to be capable of reverse injection in order to prevent nozzle clogging.

FIG. 3 shows another embodiment of the method for removing powdered garbage. A suction device 36 having the same principle as that of the electric vacuum cleaner is provided to suck the raw dust powder in the dehydration tank 1 with the suction hose 3
4 is sucked in, and the raw dust powder is stored in the raw garbage storage bag 35 which also functions as a bag filter. When the garbage storage bag 35 is full, the storage bag is taken out and replaced with an empty storage bag. The suction nozzle 38 and the garbage suction pipe 40 of FIG. 1 replace the suction hose 34.

FIG. 2 is a view showing the relationship between the dehydration tank and the air nozzle, which is a detailed view of a portion of FIG. The dehydration tank has a three-layer structure and is composed of an inner cylinder 7 as a container for containing raw garbage, a filter 4 for dehydrating only the moisture of the raw garbage, and an outer cylinder 8 for supporting the filter. Dehydration holes 3 and 5 in the inner and outer cylinders
There is a hole in it, through which water from the garbage goes out.
Since the crushed raw dust powder adheres to the inner cylinder side of the filter, air is ejected from the air nozzle 6 outside the filter to blow off the raw dust powder adhered to the filter. The filter is cleaned to eliminate clogging. After that, air is ejected from the nozzle to dry the crushed garbage. In FIG. 2, the explanation has been made on the portion a of FIG. 1, that is, on the side surface of the dehydration tank, but the same applies to the bottom of the dehydration tank. Although the dehydration tank has a three-layer structure in this embodiment, it may have a one-layer structure including only the inner cylinder. In that case,
It has a structure in which a filter is fitted into the dehydration hole of the inner cylinder.

Next, a method for treating raw garbage will be described with reference to FIG.
Will be described. First, the lid 13 of the garbage processor is opened, and the garbage is put in the dehydration tank 1. Close the lid and rotate the crushing cutter 2 to crush the garbage. The rotation of the crushing cutter is stopped, the dehydration tank 1 is rotated, the water is filtered through the dehydration hole 3 with the filter 4, only the water is taken out of the dehydration tank, and the water is drained to the drain tank 18. When the dehydration is completed, the rotation of the dehydration tank is stopped and the air is ejected from the air nozzle 6. As a result, the garbage attached to the filter is peeled off and dropped into the dehydration tank. Once dropped, stop blowing air from the side and send hot air from the bottom into the dehydration tank. The hot air from the bottom is the air heated by the heater 11,
Raise the temperature of the garbage and let it dry. At this time, the crushing cutter 2 is rotated to further crush the raw dust while stirring. The steam generated when drying the garbage is discharged from the exhaust hole 1 through a small gap with the lid 13 at the upper part of the dehydration tank 1 together with the jet air.
It is discharged through 6. Water vapor in the air is a dehumidifier 26
This causes dew to be turned into water and is poured into the discharge tank 18. The dehumidified air is deodorized by the deodorizer 27, again passes through the electromagnetic valve 28, is heated by the heater 10 at the bottom, and is ejected from the air nozzle 6 at the bottom of the dehydration tank into the dehydration tank. Since the air is not ejected from the side portion, the solenoid valve 28 of the air nozzle 6 on the side portion is closed. When air is ejected from the air nozzle 6, the air tube packing 15 is inflated and brought into close contact with the dehydration tank, and the air ejected from the air nozzle is short-circuited to the exhaust hole 16 so as not to flow out. The dried powdery garbage is sucked from the garbage suction nozzle 39 and stored in the garbage storage bag 35.

[0011]

Since the present invention is constructed as described above, it has the following effects.

The water content of raw garbage is crushed and dehydrated to remove water as mechanically as possible. As a result, the removal of water by evaporation of water by heating can be minimized, and the thermal energy for evaporating water can be greatly reduced. Therefore, it is possible to reduce the power consumption and the drying time.

Since the treated garbage can be made into a dry powder, the treated garbage can be easily post-treated.
The amount of garbage can also be significantly reduced.

Since the raw garbage can be automatically made into a dry powder form and stored in the storage bag, the raw garbage can be easily treated without soiling the hands.

Since the garbage can be crushed and dehydrated in the dehydration tank, the garbage processor can be made compact. Since it does not take up a lot of space, it can be used as a household garbage processor.

Since the filter of the dehydration tank can be backwashed with the air nozzle, the filter is not clogged.

The air for drying the food waste is recycled and used, and is not discharged to the outside. When it circulates, it goes through the deodorizer and heater each time, eliminating the smell of food waste. The drainage after dehydration is also stored in the water storage tank through the water purifier, so there is no smell of drainage.

[0018] Since raw garbage generated in kitchens of general households, kitchens of restaurants, fish stores and greengrocers can be processed into dry powder, it is sold as fertilizer or livestock feed for a fee if adhered to no impurities. It becomes possible.
