Description

Technical Field

[0001] The invention belongs to the technical field of solid-liquid separation devices for kitchen waste, and in particular relates to a solid-liquid separation device for kitchen waste. Background Art

[0002] Kitchen waste refers to the waste generated in residents' daily life and food processing, catering services, unit catering and other activities, including discarded vegetable leaves, leftovers, leftovers, fruit peels, eggshells, tea residues, bones, etc. Its main sources are family kitchens, restaurants, hotels, canteens, markets and other industries related to food processing. Kitchen waste contains extremely high moisture and organic matter, which is easy to rot and produce stench. After proper treatment and processing, it can be converted into new resources. The high organic content makes it suitable for use as fertilizer and feed after strict treatment. It can also produce biogas for fuel or power generation, and the grease part can be used to prepare biofuel. Illegal collection and recycling of kitchen waste will threaten the environment and residents' health. Separate collection of kitchen waste can reduce the amount of organic matter entering the landfill, reduce the generation of odor and leachate, and avoid the adverse effects of excessive moisture on waste incineration treatment, reducing the corrosion of equipment. The treatment of kitchen waste generally includes steps such as crushing and solid-liquid separation. Among them, the existing solid-liquid separation process uses a screen for filtration. Since the solid matter in the kitchen waste varies in size, it is easy to cause the mesh of the screen to be blocked, which requires repeated manual cleaning, which not only affects the efficiency and effect of solid-liquid separation, but also increases labor costs.

[0018] like Figure 1-3 As shown, a solid-liquid separation device for kitchen waste includes a box body 1, a lower sieve plate 2 is installed in the box body 1, and a plurality of sieve holes 12 are arranged on the lower sieve plate 2. The box body 1 includes a top cover 3 located above the lower sieve plate 2, and a bottom plate 4 located below the lower sieve plate 2. The top cover 3 is provided with a feed inlet 5, and the middle of the bottom plate 4 is gradually concave downward to form a funnel-shaped water outlet 6, and the water outlet 6 is connected to a water bucket 8 through a pipe 7, and the water outlet of the pipe 7 is located above the water bucket 8. A treatment pool 9 is arranged on the right side of the box body 1, and a lower sieve tooth 10 is arranged on the lower sieve plate 2 for sweeping the solid matter on the lower sieve plate 2 into the treatment pool 9. The right side of the box body 1 has a feed outlet 11 for the solid matter on the lower sieve plate 2 to pass through. Kitchen waste is put into the solid-liquid separation device from the feed inlet 5, and the kitchen waste is separated into solid and liquid on the lower sieve plate 2, and the liquid part flows to the bottom plate 4 and flows to the water bucket 8 along the water outlet 6 and the pipe 7. The solid part is swept into the processing tank 9 from the discharge port 11 through the lower screen teeth 10, so as to prevent the solid matter from being accumulated on the lower screen plate 2 for a long time and affecting the filtering effect of the next batch of food waste.

[0019] Furthermore, a movable plate 13 is provided between the lower sieve plate 2 and the top cover 3, the lower sieve teeth 10 are fixedly connected to the right end of the movable plate 13, the movable plate 13 is movably installed in the box body 1, and a mounting opening 14 is provided on the left side of the box body 1 for the left end of the movable plate 13 to extend out.

[0020] Furthermore, a right side rope 15 is tied to the right end of the movable plate 13, and the right side rope 15 is guided by the right guide wheel 16 and extends vertically downward and fixedly connected to the water bucket 8. A left side rope 17 is tied to the left end of the movable plate 13, and the left side rope 17 extends from the installation port 14 and is guided by the left guide wheel 18 and extends vertically downward and fixedly connected to the counterweight 19. A conical plug 20 is provided in the water bucket 8, and a conical leakage hole 21 for the conical plug 20 to be inserted into the bottom of the water bucket 8 is provided. The conical plug 20 is connected to the bottom of the water bucket 8 through a plurality of springs 22 evenly arranged in a circumference. The spring 22 keeps the conical plug 20 pulled down so that the conical plug 20 is inserted into the conical leakage hole 21. A limiting push rod 23 is provided under the water bucket 8, and the limiting push rod 23 is directly opposite to the conical leakage hole 21 and can push the conical plug 20 out of the conical leakage hole 21. When the water collected in the bucket 8 reaches a certain weight, the bucket 8 pulls the movable plate 13 to move to the right, driving the counterweight 19 to rise. During the movement of the movable plate 13 to the right, the lower screen teeth 10 sweep the solid matter on the lower screen plate 2 into the treatment tank 9 from the discharge port 11. When the lower screen teeth 10 move to the discharge port 11, the bottom of the bucket 8 contacts the limiting push rod 23, and the limiting push rod 23 overcomes the elastic force of the spring 22 to push the conical plug 20 out of the conical leakage hole 21, and the water in the bucket 8 leaks out from the conical leakage hole 21. When the water in the bucket 8 is reduced to a certain amount, the weight of the counterweight 19 is greater than the weight of the bucket 8 at this time, the counterweight 19 drops, the movable plate 13 moves to the left, and the bucket 8 rises. The limiting push rod 23 is separated from the conical leakage hole 21, and the spring 22 pulls down the conical plug 20 so that the conical plug 20 blocks the conical leakage hole 21, and the bucket 8 continues to receive water. In this way, there is no need to consume electricity, and the separated water can be used to complete the cleaning of the solid matter on the lower sieve plate 2, thereby reducing the equipment cost and the power consumption cost.

[0021] Furthermore, the movable plate 13 is provided with sieve holes 12. When the movable plate 13 is moving, a small amount of food waste is likely to fall onto the movable plate 13, and the sieve holes on the movable plate 13 can also filter the food waste falling onto the movable plate 13 for solid-liquid separation.

[0022] Furthermore, the left end of the top cover 3 is provided with an upper screen tooth 24 facing the movable plate 13. When the movable plate 13 moves to the left, the upper screen tooth 24 is used to sweep the kitchen waste that may fall on the movable plate 13 onto the lower screen plate 2, so as to prevent the kitchen waste on the movable plate 13 from affecting the normal movement of the movable plate 13.

[0023] Furthermore, the sieve holes 12 on the movable plate 13 and the sieve holes 12 on the lower sieve plate 2 are evenly spaced and are in the shape of long strips, with one end of the sieve holes 12 close to the right side of the box body 1 and the other end close to the left side of the box body 1 .

[0024] Further, the lower sieve teeth 10 include a lower mounting plate 25 and a plurality of sieve teeth fixedly connected to the lower mounting plate 25, the sieve teeth on the lower mounting plate 25 correspond one-to-one to the sieve holes 12 on the lower sieve plate 2, and the sieve teeth on the lower mounting plate 25 can be movably inserted into the corresponding sieve holes 12, and the upper sieve teeth 24 include an upper mounting plate 26 and a plurality of sieve teeth fixedly connected to the upper mounting plate 26, the sieve teeth on the upper mounting plate 26 correspond one-to-one to the sieve holes 12 on the movable plate 13, and the sieve teeth on the upper mounting plate 26 are respectively inserted into the corresponding sieve holes 12 of the movable plate 13. In this way, the sieve teeth can clean and dredge the sieve holes 12 during movement to prevent the sieve holes 12 from being blocked. The long strip sieve holes 12 on the lower sieve plate 2 play a role in limiting and guiding the movement of the movable plate 13 from below. The upper sieve teeth 24 on the top cover 3 play a role in limiting and guiding the movement of the movable plate 13 from above, so that the movable plate 13 moves more smoothly.

[0025] Furthermore, baffles 27 are respectively provided on both sides of the movable plate 13 , and a limit plate 28 is provided on the left end of the movable plate 13 .
