However, the existing devices do not have the function of pre-treating lithium carbonate during filtration, which will lead to a decrease in the filtration effect of lithium carbonate and affect the quality of subsequent lithium carbonate preparation. Therefore, a separation and filtration device for the preparation of lithium carbonate is proposed. Summary of the Utility Model

[0028] Furthermore, intermittent filtration of the solution can be carried out, which can effectively improve the filtration effect of the solution. A filter cylinder 12 is slidably arranged on the surface of the scraping plate 11, an irrigation plate 14 is fixedly communicated with the surface of the filter cylinder 12, one end of the irrigation plate 14 is fixedly connected to the perfusion bin 2, two discharge ports are arranged on one side of the perfusion bin 2 where the irrigation plate 14 is located, the sealing plate 19 is located on one side of the discharge port, and a sealing gasket is arranged at the sliding position.

[0029] Furthermore, the suspended matters and sundries in the solution can be processed in advance, which can effectively improve the utilization rate of the filter cylinder 12.

[0030] Furthermore, in order to facilitate primary filtration of the solution, a sliding rod is slidably connected inside the irrigation plate 14, a swing rod 25 is arranged on one side of the sliding rod, and a return spring is arranged on the surface of the sliding rod. The swing rod 25 is rotatably connected to the irrigation plate 14 through a pin shaft.

[0031] Further, in order to facilitate the mixing and stirring of the additive with the pre-filtered solution and further improve the quality of solution filtration, both ends of the filter cylinder 12 are rotatably connected to a plug plate 13 through a pin shaft.

[0034] The working principle and usage process of the present utility model: After the present utility model is installed, first, additives such as flocculants are added into the storage tank 4, and then an appropriate amount of lithium carbonate solution is added into the perfusion chamber 2. When it is necessary to filter the solution, at this time, the motor 5 is started to rotate, driving the rotating shaft 6 to rotate. The rotation of the rotating shaft 6 can drive the large gear 7 and the convex block 15 to rotate. The rotation of the convex block 15 can push the sliding column 18 to move up and down. The up and down movement of the sliding column 18 can drive the sealing plate 19 to slide at the opening in front of the perfusion chamber 2, and can intermittently discharge the solution inside the perfusion chamber 2 into the pouring plate 14. Through the pouring plate 14, it is poured into the filter cylinder 12 for filtration, which can avoid a large amount of solution being directly filtered, affecting the filtration effect;

[0035] When the large gear 7 rotates, it will drive the small gear 8 to rotate through meshing transmission. The rotation of the small gear 8 can drive the rotating rod 9 to rotate. The rotation of the rotating rod 9 can push the scraping plate 11 at one end of the moving rod 10 to slide inside the filter cylinder 12 through a pin shaft, which can push the filtered solid particles. At the same time, the movement of the scraping plate 11 can drive the two-side push rods 26 to move. When the solid particles pushed by the scraping plate 11 move to both ends of the filter cylinder 12, the push rods 26 can push the plug plate 13 to rotate around the pin shaft inside the filter cylinder 12, which can facilitate the solid particles to fall into the lower collection box for collection, avoiding excessive accumulation of solid particles and affecting the filtration effect of the filter cylinder 12;

[0036] Meanwhile, when the sealing plate 19 intermittently moves in front of the perfusion chamber 2, the impact force of the solution discharge can drive the cooperation blade 22 to rotate. The rotation of the cooperation blade 22 can drive the transmission rod 23 to rotate. The rotation of the transmission rod 23 can drive the fixed rod 24 to rotate. When the fixed rod 24 rotates, the slider at one end of the swing rod 25 will be pushed by the push block arranged on its surface to move towards the inside of the filling plate 14, enabling the two groups of swing rods 25 to swing around the pin shaft, thereby cleaning the solution, further preventing a large amount of solution from being discharged into the inside of the filter cartridge 12 for filtration. At the same time, since the swing rod 25 is made of activated carbon material, it can also adsorb some suspended substances in the solution, improving the pre-filtration effect of the filter cartridge 12;

[0037] Meanwhile, when the sliding column 18 moves up and down, it can drive the piston rod 20 to move up and down inside the piston cylinder 21. The up and down movement of the piston cylinder 21 can transport the additive inside the storage tank 4 to the inside of the mixing tank 3. Since the rotation shaft 6 rotates, it can drive the mixing rod 16 to rotate through the belt. The mixing rod 16 can drive the mixing blades 17 to stir the pre-filtered solution, mixing the additive with the solution and deeply filtering the impurities in the solution, effectively improving the preparation of lithium carbonate with good filtering effect.
