After working for a long time, in order to prevent the garbage from clogging the filter hole, the cleaning component is controlled to clean the filter hole to prevent the filter net from being clogged by garbage residues and affecting the dehydration effect of the kitchen waste dehydration device.

[0004] The disadvantages are that restaurant waste usually contains a large amount of oily substances and mushy starch and other substances, which have a certain fluidity and are often difficult to separate by static sedimentation. At the same time, it is also difficult to separate by filtration. When filtering and pressurizing, if the filter hole is too small, the filter screen is easily blocked, and if the filter hole is too large, the filter screen is easy to leak. Therefore, the current dehydration effect of restaurant waste is not good. Summary of the invention

[0005] The purpose of the present invention is to provide a kitchen waste dehydration device with high dehydration efficiency. The separation plate can achieve self-running during the filtration process, and can always keep the separation plate in a high-efficiency filtration state without dehydration difficulties caused by blockage.

[0006] The objective of the present invention is achieved as follows: a kitchen waste dehydration device comprises a frame, a solid-liquid separation barrel is installed on the frame, a feed barrel is arranged on the top of the frame, a feed port for feeding into the solid-liquid separation barrel is arranged at the bottom of the feed barrel, a support plate is arranged below the solid-liquid separation barrel, a discharge cone is arranged on the lower side of the support plate, the left and right sides of the solid-liquid separation barrel are respectively installed on the frame via a vertically arranged separation barrel rotating shaft, and a shaft sleeve is sleeved on the outer side of the separation barrel rotating shaft; the solid-liquid separation barrel is formed by stacking a plurality of horizontally arranged separation sheets 1 and 2, the separation sheets 1 and 2 are arranged to be spaced and interspersed with each other, the separation sheets 1 and 2 are in a circular ring shape as a whole, a circular hole is arranged on one side of the separation sheet 1 and the separation sheet 2, and two U-shaped openings are respectively arranged on the other side, and the circular hole of the separation sheet 1 is sleeved on a The two forks on the front and back sides of the frame are symmetrically arranged, and a waist-shaped hole is provided on the middle arm of the fork. A fork driving motor is provided on the upper part of the frame, and an eccentric shaft is connected to the output end of the fork driving motor. The eccentric section of the eccentric shaft is cooperatively inserted in the waist-shaped hole. A synchronous motion mechanism is provided on the main shaft sections of the two eccentric shafts on the front and back sides to make the eccentric shafts on the front and back sides rotate synchronously.

[0007] When the device is working, the large circular holes between the separation plates 1 and 2 form the inner cavity of the solid-liquid separation barrel as a whole, the upper opening of which allows food waste containing water and oil to enter, and the bottom discharge cone is used for discharging, and water, oil, mushy matter and other solids enter the solid-liquid separation barrel from the feed port at the bottom of the feed barrel. At this time, the fork drive motor works, driving the eccentric shaft to rotate, the eccentric section of the eccentric shaft to make a circular motion, and drives the fork to swing back and forth around the fork positioning shaft through the waist hole, and the shifting shaft drives the separation sheet 1 and the separation sheet 2 to move, wherein the separation sheet 1 swings back and forth around the rotating shaft of one separation barrel, and the separation sheet 2 swings around the rotating shaft of another separation barrel, so that the separation sheet 1 and the separation sheet 2 make a reciprocating dislocation motion, and the liquid in the food waste flows out from the tiny gap between the separation sheet 1 and the separation sheet 2, and then seeps out around the solid-liquid separation barrel. During the movement, the separation sheet 1 and the separation sheet 2 constantly push the internal food waste back and forth. Under the synergistic effect of gravity and pushing, the liquid in the food waste keeps seeping out, and liquids such as water and oil further seep out from the gap between the separation sheet 1 and the separation sheet 2, thereby achieving the purpose of dehydration. As the liquid continues to seep out, the pulp and small particles in the garbage continue to accumulate in the gap between the separator one and the separator two. Because the separator one and the separator two are constantly grinding against each other, the accumulated materials are constantly pushed and torn, so that the working process will not cause blockage, and the filtration efficiency is high. In addition, during the filtration process, the separator can achieve self-running, and the uneven surface between the separator one and the separator two will also self-run and make the match more precise, without causing leakage, and can always keep the separator in an efficient filtration state, and will not cause dehydration difficulties due to blockage. The device is specially used for the dehydration of kitchen waste.

[0028] The lower end of the separation barrel shaft 7 is installed in the lower bearing 21 seat 12 through the lower bearing 21, and the upper end is installed in the upper bearing 24 seat 30 through the upper bearing 24. The lower bearing 21 seat 12 and the upper bearing 24 seat 30 are fixed on the frame 18. The lower end of the sleeve 8 is provided with a lower positioning sleeve 17, and the lower positioning sleeve 17 is supported between the lower support plate 11 and the lower bearing 21 seat 12.

A pressure cover 25 is provided on the upper side of the upper bearing 24 seat 30 for protecting the bearing. At the same time, butter can be added into the bearing to ensure bearing lubrication.

[0029] A water receiving tray 16 is provided at the lower outer side of the solid-liquid separation barrel 34 , and a water outlet 15 is provided at the lower side of the water receiving tray 16 .

[0030] When the device is working, water, oil, mushy matter and other solids enter the solid-liquid separation barrel 34 from the feed port 19 at the bottom of the feed barrel 1. Figure 7 , 8As shown, at this time, the fork driving motor 2 works, drives the eccentric shaft 4 to rotate, the eccentric section 20 of the eccentric shaft 4 makes a circular motion, and drives the fork 5 to swing back and forth around the fork positioning shaft 27 through the waist-shaped hole 29, and the shifting shaft 6 drives the separation piece 1 9 and the separation piece 2 10 to move, wherein the separation piece 1 9 swings back and forth around one separation barrel rotating shaft 7, and the separation piece 2 10 swings around the other separation barrel rotating shaft 7, so that the separation piece 1 9 and the separation piece 2 10 make a reciprocating dislocation motion, and the kitchen waste The liquid in the food waste flows out from the tiny gap between the separation sheet 1 9 and the separation sheet 2 10, and then seeps outward around the solid-liquid separation barrel 34. The separation sheet 1 9 and the separation sheet 2 10 constantly push the food waste inside back and forth during the movement. Under the synergistic effect of gravity and pushing, the liquid in the food waste constantly seeps out, and liquids such as water and oil further seep out from the gap between the separation sheet 1 9 and the separation sheet 2 10, fall into the water receiving tray 16, and further leave the device from the water outlet 15. The material in the solid-liquid separation barrel 34 is dehydrated, and the dehydrated food waste is pushed by the propulsion blades 31 and discharged from the discharge port 32. During the above working process, as the liquid continues to seep out, the pulp and small particles in the garbage continue to accumulate in the gap between the separator 1 9 and the separator 2 10. Because the separator 1 9 and the separator 2 10 are constantly grinding against each other, the materials accumulated on the inner edges of the separator 1 9 and the separator 2 10 are constantly pushed and torn, destroying their blocked state, so that the liquid can continue to seep out, and the working process will not cause blockage, and its filtration efficiency is high. In addition, during the filtration process, the separator can achieve self-running, and the uneven surface between the separator 1 9 and the separator 2 10 will also self-run and make the matching more precise, without causing leakage, and can always keep the separator in an efficient filtration state, and will not cause dehydration difficulties due to blockage.
