Description

Apparatus for disposal garbage

The present invention relates to a food waste processing apparatus for treating food waste discharged from a home kitchen.

As for the conventional food waste disposal apparatus, for example, as shown in Japanese Patent Application Laid-Open No. 3-110099, the debris is crushed by a disposer to dispose of the food waste put into the inlet formed in the sink bottom of the kitchen. It is provided to be transported in an upward direction of the dewatering screen by means of a transport screw installed in the dewatering screen introduced at the bottom of the dewatering and discharged outward from the outlet formed at the upper end of the dewatering screen.

However, as the above-mentioned conventional method, the crushed food waste is transported upward by the transport screw and discharged from the outlet at the top thereof, so that when the crushed food waste is transported to the transport screw, the top surface of the transport screw is slipped. There was a problem that can not transport the crushed food waste efficiently.

As a method for solving this problem, a food waste crushing apparatus of Japanese Patent Application Laid-Open No. 5-184963 is provided. The food waste crushing treatment device is formed by connecting a bent portion projecting inwardly of the dewatering screen from the bottom to the top of the dewatering screen in a straight line. The crushed food waste is to be caught to prevent the sliding of the crushed food waste on the upper surface of the screw portion of the transport screw to transport efficiently.

However, the food waste crushing treatment device as described above is formed by connecting the bent portion in a straight line from the lower end to the upper end of the dewatering screen, so that the food waste is always caught in a fixed position when viewed in the rim direction. Therefore, the load on which the crushed food waste acts on the transport screw is concentrated on a certain position of the transport screw, and this load prevents the smooth rotation of the transport screw, leading to failure of the transport motor that rotates the transport screw. As the rotational balance of the screw worsens, there was also a problem that the tip edge of the screw portion in contact with the inside of the dewatering screen also wears out quickly.

Accordingly, a main object of the present invention is to provide a food waste disposal apparatus which enables smooth rotation of the transport screw, reduces the load on the drive means of the transport screw, and also prevents the failure of the drive means due to the increased burden. Is to provide.

Another object of the present invention is to provide a food waste disposal apparatus which is capable of improving the rotational balance of the transport screw and also suppressing the wear of the screw end edge in contact with the inner wall of the dewatering screen.

The scraping member 6 also serves to scrape off the grounded food waste adhering to the circumferential surface of the cam member 55 by the contact of the tip portion 62.

The case 4 is formed with a discharge port 41 for discharging the water separated from the crushed food waste due to dehydration when transporting the crushed food waste upward by the transport screw 5. The discharge port 41 is an overflow type that is discharged through the drain port 41 when the water separated from the dehydration exceeds a predetermined level. It is drained to the outside through the drain pipe 42 connected to the discharge port 41 to the drain groove not shown in the figure.

A processing chamber 7 for decomposing the dehydrated pulverized food waste is disposed next to the case 4 facing the discharge port 33, and the dehydrated crushed food waste is disposed at the outlet 33 by the sliding plate 71. It slips and is dropped to the bottom part in the process chamber 7.

The treatment chamber 7 is provided with a treatment tank 72 in which the crushed food waste is put into the bottom of the treatment chamber 7, and a predetermined amount of decomposition chips is contained in the treatment tank 72 in advance.

Moreover, the stirring member 73 is provided in the processing tank 72. As shown in FIG. The stirring member 73 is composed of a stirring shaft 74 horizontally installed at a predetermined height in the treatment tank 72 and a plurality of stirring rods 75 protruding outward from the stirring shaft 74. When the stirring member 73 is rotated by the driving of the stirring motor 75 connected to the end of 74, the crushed food waste put into the treatment tank 72 at the tip of the stirring rod 75 and the treatment tank ( Mix well with the disassembly chip contained in 72).

The decomposition chip is used to promote the fermentation of the crushed food waste. For example, wood chips or chaff are used.

Further, a temperature control heater 76 is provided below the bottom of the treatment tank 72, and the stirring member 76 heats the crushed food waste and the decomposition chip in the treatment tank 72 to heat the agitating member. (73) promotes the decomposition treatment of the pulverized food waste together with the stirring action.

The treatment tank 72 is provided with a fullness sense (not shown in the drawing) for detecting that the processed matter gradually contained in the treatment tank 72 is sufficiently filled by the decomposition treatment of the pulverized food waste.

An exhaust port 77 is formed above the processing chamber 7, and the exhaust port 77 is connected to an end of an exhaust pipe 78 having an exhaust fan 79 so that the other end of the exhaust pipe 78 is in front. It is connected to the space part 43 which contacted the drain port 41 in the said case 4.

The space portion 43 is blocked by the side wall of the dewatering screen 3 and the partition 44. The lower end of the partition 44 is separated by dehydration and always immersed in the water accumulated in the case 4, whereby the space 43 in the case 4 is completely enclosed with the side wall of the dewatering screen 3. It is in a state. Therefore, the odor and water generated in the processing chamber 7 introduced into the space 43 through the exhaust pipe 78 by the exhaust fan 79 do not leak to the side wall of the dewatering screen 3, but overflow from the drain 41. It is exhausted to the outside through the exhaust pipe 42 with the water.

In the present embodiment, the processing chamber 7 configured as described above and the case 4 described above are integrally provided.

Here, the sensor 56 is provided in the lower end of the transportation motor 54, The photo sensor (photo sonsor) is used for this sensor 56, for example. It is configured to indirectly detect the transport speed of the crushed food waste by the transport screw 5 by detecting the rotation speed of a fan (not shown) connected to the rotation shaft of the transport motor 54.

Next, the food waste processing by the food waste disposal apparatus comprised in this way is demonstrated.

Food waste from the home and the like is introduced with water to the inlet 11 of the sink (1) of the kitchen. The food waste put into the inlet 11 is crushed by the disposer 2 and then into the corresponding dewatering screen 3 at the inlet 31 of the dewatering screen 3 through the connecting passage 22 together with the above-mentioned water. It is introduced and transported upward along the top surface of the screw 52 of this transport screw 5 due to the forward rotation of the transport screw 5.

By transporting the screw portion 52, the crushed food waste is dewatered by separating water from the dehydration hole 32 to the outside of the dewatering screen 3, and then transported to the outlet 33 at the upper end of the dewatering screen 3. .

At this time, the crushed food waste transported along the upper surface of the screw part 52 enters into the chopped pieces 3a, 3b, and 3c, and each crushed piece 3a is opposed to the direction in which the crushed food waste is sent. ), (3b) and (3c) is caught by the side surface of the screw portion 52, the sliding of the crushed food waste can be suppressed to be efficiently transported by the transport screw (5).

In addition, since each of the pieces 3a, 3b, and 3c are eccentrically spaced from the lower end to the upper end of the dewatering screen 3, the position of the crushed food waste is evenly seen in the circumferential direction. This results in an even distribution of the load on the transport screw 5 of the crushed food waste. Therefore, the rotation of the transport screw 5 can be smoothly rotated and the burden on the transport motor 54 can be reduced, and the failure of the transport motor 54 due to the increased burden can be prevented and the transport screw 5 can be prevented. Rotational balance of the head) is also good, and wear of the leading edge of the screw portion 52 in contact with the inner wall of the dewatering screen 3 can be suppressed.

Furthermore, the concave portion 53b of the distal edge 53a of the insert plate 53 protruding from the distal edge of the screw portion 52 contacts the inner wall of the dewatering scrink 3 so that the concave portion 53b is provided. As a result, the crushed food waste adhering to the inner wall of the dewatering screen 3 can be scraped off. As a result, it is possible to prevent the transportation of the crushed food waste by the adhesion of the crushed food waste to the inner wall of the dewatering screen 3, and the crushed food waste can be efficiently transported by the transport screw 5. . In addition, clogging of the dehydration hole 32 due to crushed food waste can be prevented.

On the other hand, the water discharged to the outside of the dewatering screen 3 in the dehydration hole 32 is drained to the outside of the case 4 through the drain pipe 42 in the drain 41.

At this time, since the dehydration hole 32 is formed to the upper end of the dewatering screen 3, when a large amount of water is suddenly discharged, it does not flow down to the treatment tank 72.

When the pulverized food waste and water are separated in the dewatering screen 3, the crushed food waste is transported between the tip of the screw portion 52 of the transport screw 5 and the inner wall of the dewatering screen 3. If the speed of the pulverized food waste falls below a preset value by (5), the sensor 56 detects this case indirectly by detecting that the rotational speed of the rotating shaft falls on the transport motor 54.

As a result, in the control device (not shown), the transport screw 5 is reversely rotated, constant rotation (for example, three revolutions), and forward rotation is performed again based on the detection result of the sensor 56. In the forward rotation, the sensor 56 reversely rotates the transport screw 5 in the same manner as described above, when the sensor 56 detects a decrease in the rotational speed of the rotation shaft of the transport motor 54. Therefore, the forward rotation operation and the reverse rotation operation are repeatedly executed until the rotation axis of the transport motor 54 rotates forward or above a predetermined predetermined rotation speed.

By driving control of the transport screw 5 in this way, the transport screw 5 is actually rotated in reverse to release the jam only when food waste is caught on the screw portion 52 and the inner wall of the dewatering screen 3. This makes it possible to transport the crushed food waste upwards more efficiently.

At the periphery of the discharge port 33, the end portion 62 of the scraping member 6 contacts the circumferential surface of the cam member 54 with the rotation of the transport screw 5 so that the scraping member 6 is horizontal. The movement in the direction is repeated. The scraping member 6 is forced to discharge the pulverized food waste to the outside of the outlet 33 by an operation of moving toward the outlet 33 from the shaft center side of the transport screw 5. As the scraping member 6 discharges the crushed food waste, the crushed food waste can be smoothly discharged to the outside of the discharge port 33.

Thus, the dehydrated pulverized food waste discharged to the processing chamber 7 through the sliding plate 71 at the discharge port 33 is properly stirred with the disintegrating chip by the stirring member 73 in the processing tank 72 to heat the heater 76. Due to the heating by means of rapid fermentation and decomposition treatment.

Odor and moisture generated in the processing chamber 7 in this decomposition treatment are introduced into the space portion 43 in the case 4 through the exhaust pipe 78 from the exhaust port 77 by the exhaust fan 79 and discharged from the drain port 41. It is exhausted to the outside together with the drainage through the drain pipe 42.

As described above, when the processed material is gradually contained in the processing tank 72 by the pulverized food waste decomposition processing in the processing chamber 7 and the processed material is filled in the processing tank 72, the fullness sensor detects this. If this detection is detected, the operation is stopped and the processed material in the processing tank 72 is taken out of the processing chamber 7 through an opening / closing door (not shown). A new fixed amount of decomposition chips is introduced into the treatment tank 72, and then the pulverized food waste is decomposed in the same manner as described above.

As described above, according to the food waste treating apparatus of the present invention, the dewatering screen is formed by eccentrically extending the circumferential direction in at least two stages in an up-down direction, extending upward and downward in the circumferential direction. And the expanded portion is formed from the lower end to the upper end of the dewatering screen on the surface of the water so that the jammed position of the crushed food waste is dispersed in the circumferential direction, thereby crushing the crushed food waste. The load on the transport screw is also distributed. Therefore, it is possible to smoothly rotate the transport screw, to reduce the load on the drive means of the transport screw, to prevent the failure of the drive means due to the increased burden, and to rotate the transport screw, and to make the inside of the dewatering screen Abrasion of the tip edge of the screw portion in contact with the wall can be suppressed.

Furthermore, by installing a processing chamber that disassembles crushed food waste at the discharge port, it is possible to provide a food waste disposal device that can completely dispose of food waste discharged from homes at home, etc. It is convenient.
