Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste treatment machine for separating kitchen waste such as leftover rice produced in a kitchen into a solid component and water, and compressing and reducing the volume of the solid component.

[0002]

2. Description of the Related Art A conventional waste treatment machine for treating garbage is
It is generally composed of a shaft cylinder around which screw blades are fixed, and an outer cylinder in which a mesh portion for separating solid components and moisture is provided evenly around the outer periphery of the screw blades. , The screw blade and the shaft cylinder rotate integrally, and in the process of pushing the garbage into the discharge tube with the screw blade, the garbage is compressed and separated into a solid component and water.

[0003]

In the above-mentioned conventional waste disposal machine, since the screw blade and the shaft cylinder rotate integrally, an even angle portion is generated, and garbage is pushed out to the shaft cylinder side, and the kitchen garbage is generated. The dewatering effect of is reduced, and since the kitchen waste pushed to the barrel side is not dehydrated, it rotates in synchronization with the barrel,
Attach to the barrel.

When the garbage is attached to the shaft cylinder, it becomes a load against the rotational force of the shaft cylinder, and when the garbage that adheres increases, the load on the shaft cylinder increases and the shaft cylinder does not rotate. Therefore, it is necessary to perform maintenance such as removing the garbage attached to the shaft cylinder.

[0005] Therefore, an object of the present invention is to provide a waste treatment machine which prevents the attachment of garbage and has a high dewatering effect.

[0006]

In order to achieve the above-mentioned object, the waste treatment machine of the present invention has two cylindrical members formed of a mesh-like member and having different diameters fixedly arranged coaxially. A waste inlet and a waste outlet for treated waste are provided at both ends of the two tubular members, and a spiral rotation that rotates coaxially with the two tubular members in an annular space formed by the two tubular members. A member is provided, and the spiral rotating member compresses the waste while sending it to the discharge port to separate it into solid components and water, and compresses and reduces the solid components.

[0007]

The waste treatment machine according to the present invention sends out the thrown-in waste by the spiral rotating member between the inner cylinder and the outer cylinder,
Since the waste is compressed, the waste is dehydrated on both the inner and outer cylinders. Also, since only the spiral rotating member that sends out the waste to the inner cylinder / outer cylinder rotates, there is no even-angled part,
The thrown waste is sent to the outlet without adhering to the inner and outer cylinders.

An outer screen 7 formed of a mesh-like member having a receiving port for receiving garbage from the dust chute 3 is coaxially arranged inside the waste treatment machine main body 1 outside the inner screen 6. The outer screen 7 has a frustoconical shape with a large diameter on the inlet side and a small diameter on the outlet side.

A sealed shaft 14 is attached to the upper end of the inner screen 6, and a hollow shaft 15 is attached to the lower end of the inner screen 6 to discharge water discharged into the inner screen 6. The water flowing out further is discharged to the outside of the waste treatment machine main body 1 from the drain pipe 17 through the drain pipe 16. A water collecting hopper 9 is arranged outside the outer screen 7 to collect water scattered from the outer screen 7 and discharge the collected water through the drain pipe 17 to the outside of the waste treatment machine main body 1.

In the annular space formed by the inner and outer screens 6 and 7, a spiral screw 8 having a constant feed pitch, an inner diameter of the inner screen 6 and an outer diameter of the outer screen 7 is formed. Is rotatably disposed, and the lower end portion of the screw 8 is fixed to a disc member 18 disposed between the inner and outer screens 6 and 7 through a waterproof packing 19, and the disc member 18 is attached to the screen 6. It prevents kitchen waste from flowing out from below 7.

Reference numeral 10 is a motor for driving the screw 8. A small sprocket wheel 11 is fixed to the rotating shaft of the motor 10.
Then, the large sprocket wheel 12 fixed to the disk member 18 via the rotating ring 20 is connected by the chain 13, and the rotation of the motor 10 is transmitted to the screw 8.

At the upper ends of the inner and outer screens 6 and 7, there is attached a discharge cylinder 21 for discharging the garbage to the dust collecting basket 24. Then, in the discharge cylinder 21, the spring 2
The valve 23 pushed by 2 is provided, and the garbage that has been compressed and reduced in volume while being sent to the discharge cylinder 21 side is further compressed and reduced by the spring 22 to remove water, so that the pushing force of the garbage is more than a certain value. Valve 23 against the force of spring 22
Is opened, and the garbage is discharged from the discharge cylinder 21 to the dust collecting basket 20.

The waste treatment machine of the present invention is constructed as described above, and its operation will be described below. The small kitchen waste and water contained in the washing tub 2 fall directly to the dust chute 3 from the mesh portion of the lid 4, and the water passes from the lower part of the outer screen 7 through the water collecting hopper 9 and the drain pipe 16 to the waste treatment machine main body. 1
It flows out and the garbage is stored between the inner and outer screens 6 and 7. The large kitchen waste left in the washing tub 2 is opened in the lid 4 and thrown into the dust chute 3, and is crushed into a predetermined size or less by the crusher 5 in the dust chute 3 and the space between the inner and outer screens 6 and 7. Stored in.

The sensor 26 detects the amount of garbage stored between the inner and outer screens 6 and 7. When the amount exceeds the predetermined amount, the motor 1
0 is operated and the screw 8 is rotated. The kitchen waste stored between the inner and outer screens 6 and 7 is guided and rotated in a spiral shape by the rotation of the screw 8 and is sent out toward the discharge cylinder 21.

The kitchen waste guided by the screw 8 and sent out in the direction of the discharge cylinder 21 is compressed and dehydrated in accordance with the decrease in the cross-sectional area between the inner and outer screens 6, 7. Furthermore, the discharge tube 2
It is collected in 1 and compressed and reduced in volume at a constant pressure.
It is discharged to 4. The sensor 27 detects the amount of kitchen waste stored in the dust-collecting basket 24, stops the motor 10 when the amount reaches a predetermined amount, and displays a message on the outside of the waste processing machine body 1.

In this embodiment, the discharge cylinder 21 is provided with the valve 23 pushed by the spring 22 to further compress and reduce the volume of the garbage, but instead of the spring and the valve as shown in FIG. A short tube 121a having a required length is provided between the discharge port of the discharge tube 121 and the upper end of the screw 108, and friction resistance between the inner wall of the discharge tube 121 and the garbage adds resistance to the feeding speed of the kitchen waste to remove the garbage. May be configured to be compressed and reduced in volume. In addition, the waste treatment machine of the present invention is provided with a garbage discharge tube 21.
Since it is compressed as it is sent in the direction, the garbage can be compressed and reduced in volume without providing the spring 22 and the valve 23 in the discharge cylinder 21 as in the present embodiment.

Although the driving force of the motor 10 is transmitted by the chain 13 and the sprocket wheels 11 and 12 in the present embodiment, it may be replaced by a combination of gears. Also,
The transmission may be replaced by a pulley and a V-belt.

In this embodiment, the inner and outer screens 6 and 7 are arranged in the waste treatment machine main body 1 while being vertically inclined.
The inner and outer screens 6 and 7 may be horizontally arranged in the waste treatment machine main body 1 as long as the water separated from the garbage can be discharged smoothly.

In the present embodiment, the diameter of the outer screen 7 is changed to compress the kitchen waste stored between the inner and outer screens 6 and 7. However, the spiral pitch of the screw 8 is changed to change the charging port. It is also possible to configure so that the kitchen waste is compressed from the discharge tube 21 to the discharge tube 21.

Although the crusher 5 is provided in this embodiment, the kitchen waste may be directly put into the dust chute 3 without providing the crusher 5. However, when the crusher 5 is provided, a large solid substance can be roughly crushed and the processing efficiency is improved. Further, the required effect of the waste treatment machine main body 1 can be reduced, and the size can be reduced.

[0023]

As described above, in the waste treatment machine of the present invention, dehydration is performed with two screens inside and outside, so the dehydration efficiency is remarkably improved. Since the dewatering efficiency is proportional to the square of the dewatering layer thickness, theoretically, the effect four times as high as that of the conventional waste treatment machine performing one-sided dewatering can be obtained.

Since the inner and outer screens are fixedly arranged, synchronous rotation with the rotary shaft of the kitchen waste does not occur, adhesion of the kitchen waste to the rotary shaft can be prevented, and the number of maintenance steps can be reduced. is there.

When manufacturing a machine for treating the same amount of garbage as the conventional waste disposal machine, the machine can be downsized.
