[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5This utility model provides a solid-liquid separation device for treating lithium mica tailings: It includes a base 1, with a reaction tank 2 connected to the upper surface of the base 1. The reaction tank 2 is conical, and its bottom is connected to a sedimentation tank 8. This conical structure guides the tailings, which form flocs after stirring and reaction, to more smoothly gather at the bottom and settle into the sedimentation tank 8. An external pipe and a liquid outlet pipe are connected to the outer surface of the reaction tank 2. A support frame 3 is installed on the upper surface of the reaction tank 2, and a fixing frame 4 is connected to the upper surface of the support frame 3. A motor 5 is installed inside the fixing frame 4. The output end of the motor 5 passes through the support frame 3 and is connected to a connecting rod 6. Three stirring rods are connected to the outer surface of the connecting rod 6. The bottom of the reaction tank 2 is connected to the sedimentation tank 8. The inner wall of the sedimentation tank 8 is connected to the support frame 9. The end of the connecting rod 6 away from the motor 5 is rotatably connected to the upper surface of the support frame 9. The support frame 9 on the inner wall of the sedimentation tank 8 can ensure the stability of the stirring blade 7 when it rotates. The upper surface of the support frame 3 is equipped with a reagent box 10. The bottom wall of the reagent box 10 is connected to a water pump 34. The output end of the water pump 34 passes through the reagent box 10 and is connected to a connecting pipe 11. The upper surface of the support frame 3 is connected to a connecting plate 12. The bottom surface of the connecting plate 12 is connected to a water spray nozzle 13. The end of the connecting pipe 11 away from the reagent box 10 passes through the connecting plate 12 and is connected to the outer surface of the water spray nozzle 13.

[0018] like Figure 3 As shown, a sludge pump 14 is installed below the reaction tank 2. The input end of the sludge pump 14 is connected to a conveying pipe 15. The bottom surface of the sedimentation tank 8 is connected to a discharge pipe 16. A first electric valve 17 is installed on the outer surface of the discharge pipe 16. The sludge pump 14 generates negative pressure through its own pump body at its input end, which draws the settled tail sludge from the sedimentation tank 8 through the discharge pipe 16 and the conveying pipe 15. Then, under the power of the pump body, the tail sludge is pressurized and discharged through the conveying pipe 18 at the output end, and finally transported to the quick-connect valve 21 of the cover 20 of the vacuum box 19, providing a material basis for further solid-liquid separation in the vacuum box 19.

[0019] like Figure 3 As shown, the end of the conveying pipe 15 away from the sewage pump 14 is connected to the outer surface of the discharge pipe 16, and the output end of the sewage pump 14 is connected to the conveying pipe 18.

[0020] like Figure 1As shown, a vacuum chamber 19 is provided on the left side of the reaction tank 2. A cover 20 is movably connected to the upper surface of the vacuum chamber 19. The cover 20 adopts a snap-fit ​​structure and is directly snapped onto the vacuum chamber 19 to seal the vacuum chamber 19. When the vacuum pumping device 29 is activated to perform a vacuuming operation inside the vacuum chamber 19, as the air inside the chamber is gradually extracted, the air pressure inside the vacuum chamber 19 continuously decreases, while the external atmospheric pressure remains unchanged. Under the action of the pressure difference between the inside and outside, the outside atmosphere will exert downward pressure on the cover 20. A quick-connect valve 21 is connected to the upper surface of the cover 20. A second electric valve 22 is installed on the outer surface of the quick-connect valve 21. The end of the conveying pipe 18 away from the sewage pump 14 is connected to the quick-connect valve 21.

[0021] like Figure 5 As shown, a support plate 23 is connected to the inner wall of the vacuum chamber 19, and a filter frame 24 is movably connected to the upper surface of the support plate 23. Two handles 25 are connected to the upper surface of the filter frame 24.

[0022] like Figure 5 As shown, the outer surface of the vacuum chamber 19 is connected to a water outlet pipe 26, and a third electric valve 27 is installed on the outer surface of the water outlet pipe 26.

[0023] like Figure 4 As shown, a support plate 28 is connected to the outer surface of the vacuum chamber 19, and a vacuum pumping device 29 is connected to the upper surface of the support plate 28. The output end of the vacuum pumping device 29 passes through the vacuum chamber 19 and extends into the interior of the vacuum chamber 19. After the device is started, the power components inside it will generate mechanical movement, so that a local low-pressure area is formed in the channel connecting the device and the vacuum chamber 19. At this time, the air in the vacuum chamber 19 will be drawn into the vacuum pumping device 29 through the connection channel of the output end of the device under the action of pressure difference. Subsequently, the vacuum pumping device 29 will discharge the drawn-in air to the external environment through the exhaust structure.

[0024] like Figure 1 As shown, a connecting block 30 is connected to the outer surface of the reaction tank 2, a control box 31 is connected to the outer surface of the connecting block 30, a placement plate 32 is connected to the outer surface of the connecting block 30, and an inlet pipe 33 is movably connected to the outer surface of the placement plate 32. The end of the inlet pipe 33 away from the placement plate 32 is connected to the outer surface of the reagent box 10.

[0025] The working principle of this utility model is as follows: First, flocculant is added to reagent tank 10 through inlet pipe 33 on placement plate 32. Then, the mica lithium tailings to be treated are sent into reaction tank 2 through external pipeline. After that, water pump 34 in reagent tank 10 is started through control box 31. Water pump 34 sends flocculant to water spray nozzle 13 on bottom surface of connecting plate 12 through connecting pipe 11. Water spray nozzle 13 evenly sprays the flocculant into tailings in reaction tank 2. At the same time, motor 5 in fixing frame 4 is started through control box 31. Motor 5 drives connecting rod 6 and three stirring blades 7 on it to rotate in reaction tank 2, fully stirring tailings and flocculant to accelerate reaction. Suspended particles in tailings agglomerate into flocs and gradually settle. Because the bottom of sedimentation tank 8 is conical, the settled tailings gather in sedimentation tank 8 under the action of gravity. When the tailings in sedimentation tank 8 accumulate to a certain level, the sedimentation process continues. To a certain extent, first open the liquid outlet pipe to let the clean water flow out, then open the first electric valve 17 on the discharge pipe 16 through the control box 31 to start the sludge pump 14. The tailings are transported to the quick-connect valve 21 on the cover 20 of the vacuum box 19 through the conveying pipe 15 and the conveying pipe 18. Open the second electric valve 22 on the quick-connect valve 21, and the tailings enter the vacuum box 19 and fall into the filter frame 24 on the support plate 23. Start the vacuum device 29 on the bearing plate 28 to evacuate the vacuum box 19. The water in the tailings quickly permeates the filter frame 24. Open the third electric valve 27 on the water outlet pipe 26 to discharge the filtered water. The filter frame 24 retains the tailings solids, completing further solid-liquid separation. After the treatment is completed, the filter frame 24 can be removed from the support plate 23 through the handle 25 on the filter frame 24 for convenient subsequent treatment of the tailings solids.

[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
