Description
Technical Field
[0001] This utility model belongs to the field of waste treatment technology, and in particular relates to a solid-liquid separation device for municipal solid waste treatment. Background Technology
[0002] With the acceleration of urbanization and the improvement of residents' living standards, the amount of household waste generated is increasing day by day, putting enormous pressure on the environment. Household waste has a complex composition, including kitchen waste, paper, plastics, glass, metals, and many other materials. Kitchen waste and waste with high organic content have high water content, making them prone to rotting and emitting foul odors, breeding bacteria and insects, which not only affects environmental sanitation but may also pose a threat to residents' health. Therefore, how to effectively treat household waste, especially the solid-liquid separation process, has become one of the most urgent environmental problems to be solved.
[0003] Currently, the main methods for municipal solid waste treatment include landfill, incineration, and composting. However, these methods have many shortcomings when dealing with waste with high water content. For example, landfilling consumes a large amount of land resources, and leachate can easily pollute groundwater. Solid-liquid separation is a crucial pretreatment step in municipal solid waste treatment. The purpose of solid-liquid separation is to effectively separate the solid and liquid components in the waste for subsequent separate processing. Existing solid-liquid separation equipment is complex in structure, has high operation and maintenance costs, and is not suitable for large-scale municipal solid waste treatment.
[0004] To address these issues, we provide a solid-liquid separation device for municipal solid waste treatment. Utility Model Content

Specific Implementation Example 1
[0042] Please see Figure 1-7 This utility model is a solid-liquid separation device for municipal solid waste treatment, including a shell 1, with an installation groove 2 on the upper surface of the shell 1; first installation plates 3 are fixed to both sides of the top plate of the shell 1; second installation plates 4 are fixed to the first installation plates 3 by bolts; a processing shell 5 is fixed to one side of the second installation plate 4; a through groove 6 is opened on the top of the processing shell 5; a bracket 7 is fixed to one side of the processing shell 5; a first motor 8 is fixed to one side of the bracket 7; a transmission wheel 9 is fixed to the output shaft of the first motor 8; several first transmission blocks 10 are evenly fixed within a 180° range on the outer circumference of the transmission wheel 9; a limiting rod 11 is fixed to one side of the bracket 7; a movable rod 12 is movably connected to the outside of the limiting rod 11; a sliding groove 13 is opened on the surface of the movable rod 12; the limiting rod 11 passes through the sliding groove 13; several second transmission blocks 14 are fixed to both sides of the movable rod 12; a squeezing plate 15 is fixed to the bottom of the movable rod 12; a support plate 16 is fixed to the inner wall of the shell 1; a filter frame 17 is movably connected to the upper surface of the support plate 16; and a waste liquid collection tank 18 is movably connected to the bottom of the shell 1.
[0043] Specifically, a limiting groove 19 is opened on the upper surface of the support plate 16; a limiting strip 20 is fixed at the bottom of the filter frame 17, and the limiting strip 20 matches the limiting groove 19.
[0044] Furthermore, the first transmission block 10 is engaged with the second transmission block 14, and the transmission wheel 9 is not fixed. Half of the first transmission block 10 has a smooth curved surface.
[0045] The operation process of this embodiment is as follows: The household waste to be processed is poured into the outer shell 1, allowing it to fall into the filter frame 17; a waste liquid collection tank 18 is installed at the corresponding position at the bottom of the outer shell 1 to collect the separated waste liquid; the waste is first pre-treated by stirring, i.e., the second motor 27 installed at the bottom of the placement plates 26 on both sides of the inner wall of the outer shell 1 is started; the second motor 27 drives the stirring rod 28 on the output shaft to rotate, stirring the household waste in the filter frame 17, dispersing the waste components in the filter frame 17, which is beneficial for subsequent solid-liquid separation; then the first motor 8 on the support 7 on one side of the processing shell 5 is started, and the output shaft of the first motor 8 drives the transmission wheel 9 to rotate; the first transmission block 10, uniformly fixed within a 180° range of the outer ring of the transmission wheel 9, meshes with the second transmission block 14 fixed on both sides of the movable rod 12; when the transmission wheel 9 rotates, it drives the movable rod 12 to move up and down along the limiting rod 11; since the limiting rod 11 passes through the sliding groove 13 on the surface of the movable rod 12, and the inner walls of the limiting blocks 21 on both sides of the limiting rod 11 are rotatably connected... The rotating wheel 22 slides within the connecting grooves 23 on both sides of the inner wall of the slide 13, ensuring the stability of the movement of the movable rod 12. The squeezing plate 15, fixed at the bottom of the movable rod 12, moves up and down with the movable rod 12. The squeezing plate 15 moves up and down within the processing shell 5, squeezing the waste in the filter frame 17. Under the squeezing action, the liquid in the waste passes through the filter screen of the filter frame 17 and flows into the waste liquid collection tank 18 at the bottom of the shell 1, while the solid remains in the filter frame 17, achieving solid-liquid separation. The structural design of the transmission wheel 9 and the squeezing plate 15 is simple and reasonable, reducing the complexity of the equipment. The transmission wheel 9 is driven by the first motor 8, which drives the movable rod 12 through meshing with the second transmission block 14. The structure is compact, reducing the number of parts and lowering the probability of failure. At the same time, the cooperation of components such as the limit rod 11, the slide 13, and the rotating wheel 22 ensures the stability of the movement of the movable rod 12 and the squeezing plate 15, making the entire device more reliable during operation and reducing the risk of equipment damage caused by component shaking or instability. Specific Implementation Example 2
[0047] Please see Figure 7 Based on the first specific embodiment, limit blocks 21 are fixed on both sides of the limit rod 11, and a rotating wheel 22 is rotatably connected to the inner wall of the limit block 21; a connecting groove 23 is opened on both sides of the inner wall of the slide groove 13, and the rotating wheel 22 is slidably connected to the inner wall of the connecting groove 23.
[0048] Specifically, the top of the processing shell 5 has a movable groove 24, and a baffle 25 is fixed on one side of the extrusion plate 15; the baffle 25 matches the movable groove 24.
[0049] Furthermore, a placement plate 26 is fixed on both sides of the inner wall of the outer shell 1, and a second motor 27 is fixed at the bottom of the placement plate 26; a number of stirring rods 28 are fixed on the output shaft of the second motor 27.
[0050] The operation process of this embodiment is as follows: The top of the processing shell 5 has a movable groove 24. The baffle 25 fixed on one side of the squeezing plate 15 matches the movable groove 24, which restricts the movement trajectory of the squeezing plate 15 and prevents the garbage from overflowing. The movable groove 24 plays a precise guiding and limiting role for the squeezing plate 15. The baffle 25 fixed on one side of the squeezing plate 15 matches the movable groove 24, so that the squeezing plate 15 can only move along the trajectory defined by the movable groove 24 during the up and down movement. This ensures that the squeezing plate 15 can accurately squeeze the garbage in the filter frame 17, avoids the squeezing plate 15 from deviating or shaking during the movement, and improves the effect and stability of solid-liquid separation.
