Description

Technical Field

[0001] This utility model relates to the field of kitchen waste treatment technology, specifically a kitchen waste solid-liquid separation tank. Background Technology

[0002] Food waste refers to food scraps and food processing waste, mainly solid residues from kitchen waste. Because food waste is prone to fermentation, spoilage, and rotting, it not only produces large amounts of toxins and emits foul odors, but also pollutes water and the atmosphere. If food waste is not disposed of promptly, it not only affects the city's appearance and environmental sanitation, but also spreads diseases, endangering people's daily lives and health.

[0003] Existing solid-liquid separation devices for kitchen waste mostly involve placing the kitchen waste directly into the device and then using a designed solid-liquid separation screen or other structure to separate the solids and liquids. The waste is then discharged and transferred by gravity. However, due to the complexity of kitchen waste types, and the high water content in some leftovers, simple gravity screening is insufficient for effective solid-liquid separation. In most cases, pressure needs to be applied to achieve effective separation. However, applying pressure can easily clog the separation screen and other structures, affecting subsequent use.

[0004] Therefore, in view of the above-mentioned problems, this technical solution proposes a solid-liquid separation tank for kitchen waste. Utility Model Content

[0005] The purpose of this utility model is to provide a solid-liquid separation tank for kitchen waste to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a solid-liquid separation tank for kitchen waste, comprising a solid-liquid separation tank body, an inlet, and a waste liquid outlet; the inlet is connected to the top of the solid-liquid separation tank body, and the waste liquid outlet is connected to the bottom of the solid-liquid separation tank body; multiple parallel filter screens with progressively decreasing pore sizes are installed at equal intervals from top to bottom inside the solid-liquid separation tank body; kitchen waste undergoes multi-stage filtration along the multi-layer filter screens, classifying and screening solids and separating the contained moisture; the outer walls on both sides of the solid-liquid separation tank body located at the height areas of all filter screens are respectively... The system is equipped with a pushing mechanism box and a pressing mechanism box. The pushing mechanism box contains a pushing mechanism that pushes the waste filtered and retained on each set of filter screens toward the pressing mechanism box. The pressing mechanism box contains a pressing mechanism that longitudinally squeezes and drains the waste input by the pushing mechanism. In other words, by using the pushing mechanism and the pressing mechanism in cooperation, the waste on the filter screen is further processed, and the waste liquid contained therein is fully separated. At the same time, the separated solids are output outward along the pressing mechanism box without affecting the subsequent separation and processing of solid and liquid waste by the filter screen inside the solid-liquid separation tank.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a U-shaped pusher plate on the basis of existing solid-liquid separation, the filtered garbage is pushed into the pressure tank, and then the pressure plate is used to squeeze the filtered garbage to further remove water. Then, with the help of gravity, the solid and liquid in the garbage are fully separated. The squeezed solid garbage is output from the pressure mechanism box without affecting the subsequent filter screen for filtering the garbage again, thereby achieving efficient solid-liquid separation of kitchen waste.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Please see Figures 1-5A solid-liquid separation tank for kitchen waste includes a solid-liquid separation tank body 10, an inlet 11, and a waste liquid outlet 12. The inlet 11 is connected to the top of the solid-liquid separation tank body 10, and the waste liquid outlet 12 is connected to the bottom of the solid-liquid separation tank body 10. Multiple parallel filter screens 16 with progressively decreasing pore sizes are installed at equal intervals from top to bottom inside the solid-liquid separation tank body 10. Kitchen waste undergoes multi-stage filtration along the multiple filter screens 16, classifying and screening solids and separating the contained moisture. Pushing mechanism boxes 1 are installed on the outer walls of both sides of the solid-liquid separation tank body 10 at the height range of all filter screens 16. The push mechanism box 13 and the pressure mechanism box 14 are equipped with a push mechanism for pushing the waste retained on each set of filter screens 16 toward the pressure mechanism box 14. The pressure mechanism box 14 is equipped with a pressure mechanism for longitudinally squeezing and draining the waste input by the push mechanism. That is, by using the push mechanism and the pressure mechanism in cooperation, the waste on the filter screens 16 is further processed to fully separate the waste liquid contained therein. At the same time, the separated solids are output outward along the pressure mechanism box 14 without affecting the subsequent separation and processing of solid and liquid waste by the filter screens 16 inside the solid-liquid separation tank 10.

[0019] In this embodiment of the invention, the solid-liquid separation tank 10 has a rectangular cross-section. The filter screen 16 is provided with push plate inlet / outlet 21 and discharge port 24 at the connection between the two sides of the filter screen 16 and the push mechanism box 13 and the water pressing mechanism box 14, respectively. The push plate inlet / outlet 21 is used for the push mechanism to enter the upper side of the filter screen 16, and the discharge port 24 is used to transfer the waste controlled by the push mechanism to the water pressing mechanism. Each set of push mechanism and water pressing mechanism is provided in the push mechanism box 13 and water pressing mechanism box 14 on both sides of the filter screen 16. The push mechanism operates independently, and the water pressing mechanism is connected to a set of lifting components to synchronously control the longitudinal movement of the water pressing mechanism.

[0020] Specifically, a set of rubber baffles 34 and rubber triangular baffles 25 are respectively installed on the inner bottom of the push plate inlet / outlet 21 and the discharge port 24 on one side of the filter screen 16. The rubber baffles 34 and rubber triangular baffles 25 are used to prevent the garbage on the filter screen 16 from being transferred to the push mechanism box 13 and the water pressing mechanism box 14 when it is in a free state. At the same time, when the push component passes through the push plate inlet / outlet 21 and the discharge port 24, its elasticity will not affect the normal movement.

[0021] In one embodiment of the present invention, the pushing mechanism includes a U-shaped push plate 20 that moves along both sides of the push plate inlet and outlet 21. A hydraulic rod 18 is connected to the middle of the side of the U-shaped push plate 20 away from the filter screen 16. A hydraulic cylinder 17 is connected to the end of the hydraulic rod 18. The end of the hydraulic cylinder 17 is fixed to the side wall of the water pressure mechanism box 14. That is, by controlling the hydraulic cylinder 17 to drive the hydraulic rod 18 to move laterally, the U-shaped push plate 20 is controlled to move on the upper side of the filter screen 16, pushing the garbage stuck on the filter screen 16 into the pushing mechanism box 13.

[0022] A set of material-pushing brushes 22 are rotatably installed at the bottom of the U-shaped push plate 20. One end of the material-pushing brushes 22 is connected to a servo motor 23, and the other end is rotatably installed on the inner wall of the U-shaped push plate 20. When the servo motor 23 is started, the material-pushing brushes 22 are driven to rotate and then move with the U-shaped push plate 20 to fully transfer the waste by pushing it, thereby improving the efficiency of waste transfer.

[0023] As a preferred embodiment of the present invention, the water pressing mechanism includes multiple sets of water pressing tanks 26 arranged longitudinally and equally spaced inside the water pressing mechanism box 14. Each water pressing tank 26 is connected to a set of filter screens 16. That is, under the push of the U-shaped push plate 20, the garbage on the filter screen 16 is transferred to the water pressing tank 26 through the discharge port 24. A set of pressure plates is lifted and installed inside the water pressing tank 26. The top of the pressure plates is connected to the lifting assembly through the connecting rod 29. The lifting assembly cooperates with the connecting rod 29 to squeeze the garbage in the water pressing tank 26. A filter plate 27 is installed at the bottom of the water pressing tank 26 to separate the squeezed garbage into solid and liquid. The bottom of the filter plate 27 is connected to the inclined water guide plate 28. The end of the water guide plate 28 is connected to the connecting port 33 opened on the side wall of the solid-liquid separation tank 10. Through the transmission of the water guide plate 28 and the connecting port 33, the waste liquid squeezed out of the water pressing tank 26 is transferred to the solid-liquid separation tank 10 and then falls into the waste liquid outlet 12 for output.

[0024] A solid output port 15 is provided on one side of the water pressure tank 26 for outputting the squeezed solid outward;

[0025] Specifically, the lifting assembly includes a rotating rod rotatably disposed inside the water pressure mechanism box 14. The bottom of the rotating rod is connected to a servo motor 32, and the top is rotatably connected to the inner wall of the water pressure mechanism box 14. A nut 31 is connected to the end of the connecting rod 29. A lead screw 30 is provided on the rotating rod corresponding to the nut 31. The nut 31 moves up and down along the thread of the lead screw 30. The nut 31 is provided with a guide device to limit its rotation. That is, the servo motor 32 is started to drive the lead screw 30 to rotate, thereby synchronously controlling the up and down movement of multiple sets of nuts 31. Then, under the connection of the connecting rod 29, the pressure plate is controlled to rise and fall inside the water pressure tank 26.

[0026] The working principle of this utility model is as follows: In the idle position of this device, all the aforementioned driving components, referring to power elements, electrical components, and compatible power supplies, are connected via wires. The electrical connections between the various electrical components are completed in a sequential working order. The detailed connection methods are well-known in the field. The following mainly describes the working principle and process, without further explanation of the electrical control. During operation, the kitchen waste to be separated is fed into the solid-liquid separation tank 10 through the inlet 11. Then, under the action of gravity, it passes through multiple filter screens 16 for separation and screening. The solid and liquid remain on the filter screens 16. The liquid is output along the waste liquid outlet 12. Then, the hydraulic cylinder 17 on one side of each U-shaped push plate 20 and the servo motor 23 at the bottom of the U-shaped push plate 20 are activated to control the U-shaped push plate 20 to move and transfer the garbage on the water pressure tank 26. The garbage is then input into the water pressure tank 26 through the push plate inlet and outlet 21. Then, the servo motor 32 is activated to drive the lead screw 30 to rotate, controlling the pressure plate in each water pressure tank 26 to squeeze the garbage. The waste liquid is then squeezed out and transferred to the waste liquid outlet 12 through the filter plate 27, the water guide plate 28, and the connecting port 33. The solid is then output through the solid output port 15.

[0027] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
