Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for easily treating garbage discharged from a kitchen at home and an apparatus used therefor. It is intended to provide a method that does not have to worry about clogging or the like.

[0002]

2. Description of the Related Art Out of combustible waste discharged from ordinary households,
Garbage accounts for about one-third of the garbage, which has a lot of water and tends to decay. A conventional household garbage disposer is a type of decomposition and volume reduction by bacteria, has a high facility cost, and has a large device, and thus has not been widely used. Also, the method of crushing garbage with a disposer and flowing it into sewage is not permitted in apartment buildings and many municipalities because it does not match the sewer design in Japan. For this reason, household garbage is generally treated by placing garbage with a high moisture content in a plastic bag and discharging it to a predetermined collection place. It has been plagued with foul odors from rot at collection sites where it is often left unattended, and sewage leaking from plastic bags.

[0003]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention completely prevents the generation of bad smell due to garbage at home with a simple device, and reduces the volume of garbage to facilitate handling. The present invention provides a processing method and an apparatus therefor.

[0004]

According to the present invention, garbage is pulverized by a disposer, dehydrated by a press into a cake, and the cake is inserted into a plastic bag arranged in close contact with an outlet of the press. And a method of treating garbage for sealing the mouth of the bag, a receiving port for receiving garbage crushed by the disposer, a cylinder for containing the garbage, and a garbage moving along the inner wall of the cylinder. Piston, a surface of the cylinder facing the piston or a dewatering filter provided on the piston, a power mechanism for driving the piston, and a moving direction of the dewatered cake in the cylinder. A discharge mechanism for pushing out in a direction perpendicular to the opening, a plastic bag provided in close contact with a cake outlet of the discharge mechanism, and a mouth of the plastic bag. A food waste disposal system comprising a means for sealing the.

The details will be described below with reference to the drawings.
1 to 4 are sectional views of a specific example of the device of the present invention. Because of the small size of the device, it can be housed under a kitchen kitchen sink. The garbage crushed by the disposer 1 enters the cylinder 2 of the apparatus of the present invention in the form of a slurry (FIG. 1). This is dewatered by applying pressure by a power mechanism 5 with a piston 4 having a number of holes 3 through which water can pass (FIG. 2). The dehydrated cake 15 is moved to the position of the cake discharge port 7 by the piston 6 provided at the other end in the cylinder 2 (FIG. 3). The cake 15 is pressed against the discharge port 7 by the laterally-pushed discharge mechanism 14 and is put into a plastic bag 16 arranged in close contact with the discharge port 7 (FIG. 4). Thereafter, preferably, the pressure in the plastic bag 16 is reduced, and the mouth of the bag is sealed by means 17 such as heat and pressure. When the pressure inside the plastic bag is reduced, there is little air in contact with the cake, so that there is an effect of slowing down putrefaction. It is desirable that these series of operations be automated.

Cylinder 2 in contact with crushed garbage
It is desirable to use stainless steel for the material of the piston and pistons 4 and 6 because of the need for rust prevention. However, it is also necessary to use a steel material that has been subjected to a special surface treatment (for example, Altec X treatment by Meiho Engineering) for cost reduction. Can be. The hole 3 provided in the piston 4 may be provided in the other piston 6. To prevent clogging, the piston 4
Alternatively, a layer of paper, cloth, or the like may be provided on the surface of 6. It is desirable to interpose an O-ring 10 in the gap between the piston 4 and the cylinder 2 in order to effectively pressurize, to improve airtightness, and to reduce resistance to movement of the piston. Further, it is desirable to provide an O-ring 13 at the part where the drive shaft 11 of the piston penetrates the partition wall 12 of the cylinder in order to increase the airtightness and prevent the odor from leaking. The power mechanism 5 of the piston 4 can use a deceleration mechanism using hydraulic pressure or gears. In particular, when hydraulic pressure is used, dehydration can be sufficiently performed at a high pressure, and the effect of preventing corruption and reducing the volume is great, and the hydraulic machine operates. If a noise-type motor is used, the noise that may be a concern at that time can be reduced to a level that hardly causes a problem. When the solid content concentration in the slurry is low and the amount of cake obtained by one pressure dehydration is small, this pressure dehydration is repeated several times, and after a plurality of cakes are put in a plastic bag, The inside may be reduced in pressure and sealed. As the means for sealing the mouth of the bag, there are a method of cutting simultaneously with thermocompression bonding, and a method of sandwiching the mouth with electrodes from both sides and simultaneously performing welding and cutting by an impulse by current.

[0007]

As is apparent from the above description, according to the method and apparatus of the present invention, the following effects are recognized. 1. The generation of odor in the kitchen at home can be completely eliminated. 2. You can use the disposer regardless of regulations.
Garbage disposal is simplified. 3. Small, simple, low-cost device. 4. The solid content is not discharged to the sewage, and the load of sewage treatment is small. 5. It is only necessary to dispose of a small amount of solid matter that has been reduced in volume and sealed, and is easy to handle. The odor at the garbage collection area is also eliminated.
