Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention shreds, dehydrates, etc. kitchen waste, etc.
The present invention relates to a compact garbage disposal device that compresses food waste.

(Prior Art) Conventionally, as a processing device for kitchen waste, etc., a crusher (hereinafter referred to as a disposer) that pulverizes food waste into small pieces and disposes it into a sewer system has been used.

Disposers were developed in the United States and entered Japan about 20 years ago. It is installed under the sink, and when the switch is turned on, a blade rotated by a motor can crush the food waste thrown in into small pieces and flush them into the sewer. It was first adopted by restaurants and hotels because it can crush the bones of fish and birds, and it saves the hassle of having to throw away food waste.
However, about 10 years ago, cheap domestic products became available, and they began to become popular in ordinary households, especially those living in condominiums and apartments.

(Problem to be solved by the invention) When using a disposer, there is a risk that finely crushed garbage and fat may stick to the sewer pipes and clog them.
The burden on sewage treatment will almost double.

In addition, when used in areas without sewage systems, finely crushed food waste from disposers flows directly into rivers, causing BOD, an indicator of pollution, to skyrocket, making river pollution an even more serious problem.

Examples of devices that attempt to solve these problems include the cooking residue processing machine disclosed in Japanese Utility Model Publication No. 49-69562, the crushing washing dehydrator disclosed in Japanese Utility Model Publication No. 59-25482, and the There is a kitchen waste processing machine disclosed in Japanese Patent No. 55916.

All of these devices are configured to separate and discharge water from food waste, etc., but they have a poor dehydration effect to separate water from food waste, etc. Since the compression mechanism and compression effect on the food waste for separation were insufficient, there was a problem in that the discharged food waste often remained impregnated with moisture.

Moreover, the conventional examples shown above have a large main body as a whole, and it is difficult to easily install it under a kitchen sink.

The object of the present invention is to easily shred food waste into small pieces, completely dehydrate the food waste, and compress the food waste into small pieces for disposal. It is easy to dispose of, and by discharging only the water generated by dehydration into the drainage pipe, there is no inconvenience such as clogging of sewer pipes, etc., the burden of sewage treatment is small, and the problem of river pollution can be eliminated. The purpose of the present invention is to provide a garbage processing device. It also provided a compact processing device.

(Means for Solving the Problems) In order to solve the above problems, a cylindrical shredding section for food waste and a cylindrical compression section, which are erected side by side through a common partition, are connected in a cylindrical lower part. Longitudinal section abbreviated to U depending on the path
This is a garbage disposal device that is connected to the shape of a letter, and is configured so that the garbage dehydrated and shredded in the shredding section is gradually compressed into smaller pieces in the compression section, further dehydrated, and then discharged. A cylindrical wall and a cylindrical water-permeable plate arranged with an appropriate gap inside the cylindrical wall are provided in the shredding section into which food waste is input. There is a screw for dehydrating food waste that becomes smaller and smaller towards the bottom, and a cutter for shredding food waste is attached to the bottom of this screw, and there are many small holes through which the shredded food waste passes. is arranged at the bottom of the shredding section so that the bottom plate provided with the cutter is in sliding contact with the rotating cutter, and the water that comes out from the water-permeable plate into the cylindrical wall flows to the bottom of the partition wall that divides the shredding section and the compression section. The garbage is sent to the lower part of the cylindrical wall of the compression section through the formed drainage port, while the garbage that has been shredded and dehydrated in the shredding section is sent to the compression section from the bottom plate through the lower communication path. This compression part is equipped with a cylindrical wall and a cylindrical water-permeable plate arranged with an appropriate gap inside the cylindrical wall, and the pitch of the screw blades in this cylindrical water-permeable plate becomes smaller toward the upper side. A screw for dehydrating and compressing food waste is arranged, which increases in size as the diameter of the body increases toward the top. An outlet is provided, and the water discharged from the permeable plate into the cylindrical wall and the water sent from the aforementioned shredded section are drained from the lower part of the compression section.

(Function) Food waste thrown into the shredding section from the kitchen sink is
The garbage in the shredded section is compressed by the screw for dehydration and conveyed downward, and is conveyed downward while being dehydrated. Also,
At the bottom of the shredding section, the garbage is shredded into small pieces by a cutter and sent to the communication path through the many small holes in the bottom plate.

The shredded and dehydrated food waste that enters the compression section from this communication path is sent upward while being compressed by the food waste dehydration and compression screw, and is completely dehydrated and discharged from the discharge port in a reduced size state.

Furthermore, water generated by dewatering passes through the water-permeable plate of the shredding portion and the water-permeable plate of the compression portion, and is drained from the lower part of the compression portion to the outside (drain water pipe, etc.).

(Embodiment) The drawings show an embodiment of the garbage processing apparatus of the present invention.

In the food waste processing apparatus 1 of the present invention, a food waste shredding part 2 and a compression part 3, which are vertically arranged side by side with a common partition 14 in between, are connected to each other through a lower communication passage 15 in a substantially U-shaped longitudinal section. It is being The garbage that has been shredded and dehydrated in the shredding section 2 is gradually compressed into smaller pieces in the compression section 3, and is completely dehydrated and discharged.

The garbage shredding section 2 and the compression section 3 are arranged side by side with a common partition wall, and the lower bottom section 2
A, 3a are communicated through a lower communication path 15.

Inside the cylindrical garbage shredding section 2 and compression section 3, cylindrical water-permeable plates 6 and 7 are mounted at appropriate gaps from the cylindrical walls 2b and 3b, respectively. These water-permeable plates 6 and 7 are like so-called punched metal in which many small holes are formed. These small holes are large enough to allow water to pass through, but not finely shredded garbage.

The cylindrical water permeable plate 6 is fixed to an upper inner flange 2c formed at the upper end of the cylindrical wall 2b and a lower inner flange 2d formed at the lower end of the cylindrical wall 2b. The cylindrical water-permeable plate 7 also includes an upper inner flange 3c formed at the upper end of the cylindrical wall 3b, and a lower inner flange 3d formed at the lower end of the cylindrical wall 3b.

Further, the rotating cutter 13 is in sliding contact with the upper surface of the bottom plate 12, and together with the bottom plate 12, the garbage can be efficiently shredded.

The screw 5 pushes up the garbage finely shredded by the shredding part 2 to the upper part of the compression part 3 while dehydrating and compressing it. Reference numeral 14 denotes a common partition wall that separates the garbage into the shredding section 2 and the compression section 3. A communication passage 15 is provided between the lower end of this partition wall 14 and the bottom wall 8 described above.
is formed. The food waste is sent from the shredding section 2 to the compression section 3 via this communication path 15. The shaft 5b of the screw 5 becomes thicker as it goes upwards, and the pitch of the screw blades 5a becomes smaller as it goes upwards. The outer circumferential surface of the screw blade 5a rotates so close to the inner circumferential surface of the cylindrical water-permeable plate 7 that it almost comes into sliding contact. Screw 5
is formed in this way, the food waste that enters the lower end of the compression part 3 is carried upward by the screw blade 5a, and since the shaft 5b becomes thicker as it goes upward, the food waste gradually becomes stronger. It is compressed by force.

A substantially hemispherical upper lid 16 is attached to the upper end of the cylindrical wall 3b of the compression section 3, and a discharge port 17 for discharging the dehydrated and compressed garbage is formed on one side of the upper lid 16. .

Reference numeral 18 denotes a discharge pipe extending from the discharge port 17, and a plastic bag called a garbage bag is attached to the tip of the discharge pipe 18. Once a certain amount of garbage has accumulated in this plastic bag, remove it and dispose of it. Note that the cross-sectional shapes of the discharge port 17 and the discharge pipe 18 are preferably approximately oblong ellipses.

The upper end of the shaft 10 is supported by the top of the upper lid 16.

Reference numeral 19 denotes a drainage pipe provided at the lower end of the cylindrical wall 3b, through which water discharged when the garbage is shredded or compressed is discharged to the outside of the apparatus. Reference numeral 20 is a water conduit pipe connected to this drain pipe 19. Further, reference numeral 21 denotes a drainage port formed at the lower end of the partition wall 14, through which part of the water discharged from the shredded portion 2 is drained toward the lower part of the compression portion 3.

Symbols 22a and 22b are both shafts 9 and 1.
A case of bearings 23a, 23b is provided at the lower part of the bottom wall 8 to hold the 0 so that it can rotate smoothly. Shafts 9, 10 are located at the lower ends of the shafts 9, 10 that protrude downward from the bottom wall 8.
A sprocket is attached to which the chain that transmits the driving force that rotates the motor is wound. Shaft 9
A double sprocket 24 is attached to the shaft 10, and a single sprocket 25 is attached to the shaft 10. This attachment may be reversed. That is, the double sprocket 24 may be attached to the shaft 10. A driving chain is wound around one sprocket 24b of the double sprocket 24 and a sprocket of a motor (not shown). Also, the other sprocket 24a of the duffle sprocket 24 and the shaft 10
A driving force transmission chain is wound around the single sprocket 25. The drive chain and the drive force transmission chain are both omitted from illustration. Numerals 29a and 29b are nuts for fixing the sprocket. Note that the rotation speed of the motor is greatly reduced, and is set to, for example, about 3 to 20 rotations per minute.

Note that the reference numeral 26 is a garbage introduction pipe connected to the cylindrical wall 2b of the shredding section 2. The introduction pipe 26 and the cylindrical wall 2b are fixed together, and the cylindrical wall 3b and the upper cover 16 are fixed by screws 27. In addition, 28... is an O-ring for sealing.

The garbage disposal device 1 configured in this manner is attached to an outlet 31 formed in a tank 30 of a sink. This attachment means is not limited, but may be carried out, for example, as follows.

The flange 32 of the connecting pipe 33 having a flange 32 on the outer periphery of one end is connected to the periphery 31a of the outlet 31 of the tank 30.
from above. Then, the connecting pipe 33 and the introduction pipe 26 described above are connected with a thick rubber sleeve 34. Reference numerals 35 and 35 indicate wires that fasten the rubber sleeve 34, the connecting tube 33, and the introduction tube 26. Two donut-shaped ring plates 36 and 37 are fitted into the body of the connecting tube 33 in an overlapping manner. Several screw holes are formed in the ring plate 37 located below, and screws 38 are screwed into these screw holes from below. When the screws 38 are screwed in, a force acts to push the ring plate 37 downward and the ring plate 36 upward. The ring plate 37 is prevented from moving downward from this position by a rubber sleeve 34. Therefore, the ring plate 36
There is a strong force moving upward. Therefore, the peripheral edge 31a of the outlet 31 is clamped and fixed between the ring plate 36 and the flange 32 of the connecting pipe 33, and the garbage disposal device 1 is attached to the outlet 31 formed in the tank 30 of the sink. . In addition, in a sink that is usually commercially available, the periphery 3 of the outlet 31
1a is formed as a step slightly lowered from the bottom plate 30a of the tank 30. Therefore, when the garbage disposal device 1 is attached to the sink, the connecting pipe 33
The protruding flange 32 does not protrude above the bottom plate 30a of the tank 30.

Connect the connecting tube 33 and the introduction tube 26 with a rubber sleeve 3.
4, the garbage disposal device 1 can be installed at an angle with respect to the sink. Further, since the sleeve 34 can absorb vibrations caused by operating the garbage disposal device 1, the installation is stable.

Next, how to use the garbage processing apparatus of the present invention constructed as described above will be explained.

The opening of the connecting pipe 33 from the tank 30 of the sink,
The garbage introduced through the sleeve 34 and the introduction pipe 26 is finely shredded in the shredding section 2. By pushing the screw 4, the cutter 13 shreds the garbage into small pieces, and only the finely shredded garbage is pushed out from the small holes 12a of the bottom plate 12.

Although not shown, the opening of the connecting pipe 33 is normally closed with something like punching metal with a small hole through which only water can pass.

The water that comes out of the garbage when it is pushed by the screw 4 flows from the water-permeable plate 6 to the water-permeable plate 6 and the cylindrical wall 2b.
It is served in the gap between. The water collected in this gap is discharged from the discharge port 21 through the lower part of the compression section 3 and out of the apparatus from the drain pipe 19.

The food waste finely shredded in the shredding section 2 is transferred to the communication path 1.
5 and enters the lower part of the compression section 3, and is pushed upward while compressing the inside of the compression section 3 with the screw 5. Therefore, the food waste is further dehydrated, compressed into small pieces, and discharged from the apparatus through the discharge port 17 and the discharge pipe 18. Discharge pipe 1
Attach a plastic bag to the tip of No. 8 to catch the dehydrated and compressed garbage that comes out. Once a suitable amount of garbage has accumulated in the plastic bag, dispose of it.

The water dehydrated in the compression section 3 is transferred from the water-permeable plate 7 to the cylinder wall 3.
It is served within b. The water discharged into the cylindrical wall 3b is discharged to the outside of the apparatus through the drain pipe 19.

(Effect of the invention) The shredding and dehydration of food waste are performed continuously, and the dehydrated food waste is compressed into small pieces and comes out, making it easy to dispose of.

The water from the garbage is discharged from the device through a drainage pipe and treated separately from the garbage. Therefore, there is no inconvenience such as sewage pipes becoming clogged with garbage, etc., and the burden of sewage treatment is small.
The problem of river pollution will also disappear.

Since the entire device is compact and approximately U-shaped in longitudinal section, it can be easily installed at the bottom of a sink.

Food waste containing water is input from above the shredding section, and the food waste is sent downward while being dehydrated by the food waste dehydration and downward feeding screw. The food waste, which is heavy due to moisture at the time of input, is efficiently dehydrated and sent downward.
A cutter attached to the bottom of the screw sends the garbage downward and shreds it. Since the cutter is attached to the screw, the structure for feeding, shredding, and dewatering garbage is compact.

The dehydrated and shredded food waste is sent from the communication path to the compression section. The screw for dewatering and compressing food waste disposed in the compression section has a diameter of the body section that increases toward the top, and a pitch of the screw blades that decreases toward the top. Therefore, as the garbage goes up, the pressure increases, and the garbage is completely dehydrated and compressed before being discharged.

Moreover, the cylindrical shredding section and the cylindrical compression section are arranged vertically side by side with a common partition wall interposed therebetween, and both are communicated through a cylindrical lower communication passage. As described above, the garbage disposal apparatus has a substantially U-shaped longitudinal section. Therefore, the entire device is compact and can be easily stored under a household sink. The dehydration of food waste is done in both the shredding section and the compression section, making it complete. Therefore, the moisture is completely removed from the food waste processed by this food waste processing device, and the volume is smaller, making it easier to dispose of or incinerate.
