[0002] Soil pollution often results from improper handling or discharge of solid waste, which may contain harmful substances such as heavy metals and chemical pollutants. When these wastes are discharged directly into the environment without proper treatment, they can enter the soil through infiltration, leaching and other means, changing the properties and structure of the soil and causing pollution.

[0003] In the solid waste treatment for soil pollution, the solid-liquid separation device plays a key role in effectively separating solid particles from liquid. A Chinese patent discloses a solid-liquid separation device for solid waste treatment for soil pollution (publication number: CN217230528U) which includes a box body, a U-shaped separation net sleeve is fixed on the inside upper side of the box body, a drive rod is rotatably arranged inside the flat section of the U-shaped separation net sleeve on the side wall of the box body, a spiral extrusion leaf is fixedly sleeved on the rod wall of the two drive rods, a drive mechanism is connected to the two drive rods, a feed hopper is fixedly connected to the top of the box body at the feed end of the U-shaped separation net sleeve, and a discharge hopper is fixedly connected to the side wall of the box body at the discharge end of the U-shaped separation net sleeve. This application can continuously perform solid-liquid separation work on a large amount of sludge, is easy to use, has high separation efficiency, can reduce water resource waste, and is convenient and simple to clean the U-shaped separation net sleeve and can perform sludge filtration work on the discharged water flow again.

[0004] This patent technology has significant advantages when used, but still has some shortcomings in the process of use. The U-shaped solid-liquid separation structure is prone to soil blockage, affecting the stability of the equipment, and the extruded soil is extruded into lumps, affecting subsequent drying, transportation or landfill treatment. Therefore, we propose a solid-liquid separation device for solid waste treatment for soil pollution to solve the existing problems. SUMMARY

[0005] The utility model aims at the problems in the background art and proposes a solid-liquid separation device for solid waste treatment for soil pollution.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a solid-liquid separation device for treating solid waste in soil pollution, comprising a grid cylinder, a loosening tube, a bottom plate, a motor, a rotating shaft, and a side plate. A cylindrical filter cartridge is fixed to the inner wall of the grid cylinder. A hopper is installed inside the upper side of the filter cartridge. A motor is installed on one side of the grid cylinder. A rotating shaft is installed at the output end of the motor. Spirally distributed and rotatably installed inside the filter cartridge are provided on the outer wall of the rotating shaft. A side plate is provided on one side of the grid cylinder. An annular discharge nozzle is provided between the side plate and the grid cylinder. A loosening tube is provided on the lower side of the grid cylinder. A receiving hopper is connected to the upper end of the loosening tube. A driven shaft is provided inside the loosening tube.

The design of the loosening cavity further enhances the loosening effect of the loosening pipe on lumpy soil.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The hopper of this utility model conveys the solid-liquid mixture into the grid cylinder. The solid-liquid mixture is conveyed by the auger blades. During the conveying process, the solid-liquid mixture is squeezed out, and the water inside is squeezed out. After passing through the filter cylinder, it is discharged through the grid cylinder. The grid cylinder opening is provided with a side plate, which applies resistance to the squeezed solid-liquid mixture. When the mixture is squeezed through the discharge nozzle of the lower diameter, the water separation effect during solid-liquid separation is improved, and the blockage of the solid-liquid mixture is avoided.

[0015] Meanwhile, the solids after solid-liquid separation enter the loosening pipe and are broken up by impact, which facilitates the subsequent transportation, mixing or backfilling of soil. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] likeFigures 1-5 As shown, this utility model proposes a solid-liquid separation device for treating solid waste in soil pollution, comprising a grid cylinder 2, a loosening pipe 4, a base plate 6, a motor 10, a rotating shaft 14, and a side plate 25. A cylindrical filter cartridge 13 is fixed to the inner wall of the grid cylinder 2. A hopper 1 is internally connected to one side of the upper end of the filter cartridge 13. The motor 10 is located on one side of the grid cylinder 2, and a rotating shaft 14 is located at the output end of the motor 10. Spiral blades 12 are spirally distributed and rotatably installed inside the filter cartridge 13 on the outer wall of the rotating shaft 14. A side plate 25 is located on one side of the grid cylinder 2, and an annular discharge nozzle 26 is provided between the side plate 25 and the grid cylinder 2.

[0024] A connecting rod 15 arranged in a ring array is provided between the side plate 25 and the grid cylinder 2, and a support rod 22 arranged in a ring array and attached to the outer wall of the filter cylinder 13 is provided on the inner wall of the grid cylinder 2.

[0025] A receiving groove 11 is provided above the conveying base plate 6 and is sleeved on the outer side of the lower end of the grid cylinder 2, and a drain pipe 9 is provided at the lower end of the receiving groove 11;

[0026] Based on the implementation steps of Example 1: The solid-liquid mixture enters the filter cylinder 13 inside the grid cylinder 2 through the hopper 1. The filter cylinder 13 has a cylindrical structure and a surface with filtering function, allowing liquid to pass through while trapping solid waste. The motor 10 drives the rotating shaft 14 to rotate. The outer wall of the rotating shaft 14 is equipped with spirally distributed augers 12. During the rotation, the augers 12 aug and squeeze the solid-liquid mixture, causing the liquid in the mixture to be squeezed out and discharged through the pores of the filter cylinder 13, entering the receiving groove 11 outside the grid cylinder 2, and finally being discharged through the drain pipe 9. The solid waste is then trapped by the augers 12. Pushed towards the opening of the grid cylinder 2, a side plate 25 is provided on one side of the grid cylinder 2, forming an annular discharge nozzle 26 between the side plate 25 and the grid cylinder 2. Under the push of the auger 12, solid waste is squeezed and discharged through the discharge nozzle 26. The design of the side plate 25 increases the resistance to solid waste discharge, further improving the solid-liquid separation effect, while avoiding clogging problems. Traditional solid-liquid separation devices such as U-shaped separation structures are prone to mud clogging, affecting separation efficiency. The combination of auger 12 squeezing and filter cylinder 13 filtration significantly improves the efficiency of solid-liquid separation, while avoiding clogging problems.

[0027] like Figures 1-5 As shown, compared with Embodiment 1, the solid-liquid separation device for solid waste treatment of soil pollution proposed in this utility model further includes: a loosening pipe 4 is provided on one side below the grid cylinder 2, and a receiving hopper 3 is connected to the upper end of the loosening pipe 4.

[0028] The loosening tube 4 is equipped with a driven shaft 16 inside, and multiple loosening rods 17 arranged in a ring array are provided on the outer wall of the driven shaft 16; a mounting box 5 is fixed above the base plate 6, and a guide surface 24 is provided at the upper end of the mounting box 5.

[0029] Driven shaft 16 is rotatably mounted inside the mounting box 5 at its lower end. A bevel gear 18 is provided at one end of the driven shaft inside the mounting box 5. Driven shaft 7 is rotatably mounted inside the mounting box 5. A bevel gear 19 that meshes with bevel gear 18 is provided at one end of driven shaft 7.

[0030] A drive wheel 21 is sleeved on the outer wall of the rotating shaft 14, and a driven wheel 20 is sleeved on the outer wall of the driven shaft 7. Both the drive wheel 21 and the driven wheel 20 are sleeved on the outer walls.

[0031] The inner wall of the loosening tube 4 has multiple sets of longitudinally distributed loosening cavities 23 with a radius larger than that of the loosening tube 4. The connection between the loosening cavity 23 and the loosening tube 4 is a sloping transition.

[0032] In this embodiment, solid waste discharged from the discharge nozzle 26 enters the loosening pipe 4. The loosening pipe 4 is equipped with a driven shaft 16. Multiple sets of loosening rods 17 arranged in a circular array are installed on the outer wall of the driven shaft 16. The driven shaft 16 is driven to rotate by a motor 10 through the meshing of bevel gear 18 and bevel gear 19, causing the loosening rods 17 to strike and loosen the solid waste, preventing clumping and facilitating subsequent transportation, mixing, or backfilling. The power of the motor 10 is transmitted to the drive wheel 21 through the rotating shaft 14. The drive wheel 21 drives the driven wheel 20 to rotate via the belt 8, thereby driving the driven shaft 7 and the driven shaft 16. This linkage design ensures the synchronization of the winch 12 and the loosening rods 17. The operation improves the overall efficiency of the device. The inner wall of the loosening tube 4 is provided with multiple sets of longitudinally distributed loosening chambers 23. The design of the loosening chambers 23 extends the residence time of solid waste in the loosening tube 4, enhances the impact effect of the loosening rod 17 on the solid waste, and further improves the loosening efficiency. In traditional devices, the solid waste separated is often squeezed into blocks, which is not conducive to subsequent processing. Through the design of the loosening tube 4 and the loosening rod 17, the solid waste is impacted and loosened to prevent agglomeration and facilitate subsequent transportation, mixing or backfilling. Through the linkage design of the drive wheel 21, driven wheel 20 and belt 8, stable power transmission and efficient energy utilization are achieved, reducing the operating cost and the maintenance cost of subsequent power equipment.

[0033] The above specific embodiments are merely several preferred embodiments of this utility model.
