[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. 0]

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution: a fine filtration device for the production of lithium sulfate solution, including a cylinder shell 1, an upper cover plate 2, a protective shell 3, a gear 4, a rack 5, a support block 6, an electric telescopic rod 7, a connecting rod 8, an extrusion plate 9, a double-edge blade 10, a baffle plate 11, a filter barrel 12, a spring 13, a baffle 14, a liquid outlet 15, and a screw cap 16.

[0026] The protective shell 3 is installed inside the cylinder shell 1. A gear 4 is arranged inside the protective shell 3, and a connecting rod 8 is connected to the lower end of the gear 4. Moreover, a rack 5 is connected to the left end of the gear 4. Support blocks 6 are arranged at both the front and rear ends of the rack 5, and an electric telescopic rod 7 is connected to the front end of the rack 5. The lower end of the connecting rod 8 is connected to an extrusion plate 9, and double-edge blades 10 are installed on both the front and back sides of the extrusion plate 9;

[0027] The partition plate 11 is installed at the left end of the extrusion plate 9. The outer end of the partition plate 11 is connected to a filter barrel 12. A spring 13 is installed inside the left end of the filter barrel 12. The upper end of the spring 13 is installed with a baffle 14. A liquid outlet 15 is arranged at the lower end of the filter barrel 12. A screw cap 16 is installed at the lower end of the liquid outlet 15.

[0028] As Figure 1 and Figure 3 shown, the left end of the upper cover plate 2 is connected to the cylinder shell 1 in a snap-fastening manner. The right end of the upper cover plate 2 forms a rotating structure with the cylinder shell 1. The left end of the gear 4 is connected to the rack 5 in a meshing manner. The rack 5 forms a sliding structure inside the support block 6. When using this fine filtration device, first unlock the left end of the upper cover plate 2, turn the upper cover plate 2 to the right to open the device. Then, the lithium sulfate solution can be directly poured from above the device. After being filtered by the filter barrel 12, it accumulates in the lower cavity of the cylinder shell 1. At this time, rotating the screw cap 16 can obtain the finely filtered solution. The upper end of the filter barrel 12 is connected to the cylinder shell 1 in a snap-fastening manner. This design facilitates the dumping of impurities inside the filter barrel 12, and also facilitates the disassembly, cleaning and replacement of the filter barrel 12. And when dumping, the spring 13 will vibrate, which is convenient for the separation of solid impurities.

[0029] As Figure 1 , Figure 2 and Figure 4 shown, the lower end of the connecting rod 8 is connected to the extrusion plate 9 in a snap-fastening manner. A plurality of circular slots are equally spaced on the surface of the connecting rod 8. The extrusion plate 9 forms a rotating structure at the right end of the partition plate 11. Double-edged blades 10 are equally spaced on the front and back surfaces of the extrusion plate 9. The lower left side of the filter barrel 12 is in a hexagonal countersunk head structure. Inside the structure, a gear 4 in a 1 / 4 circular arc shape is connected by a spring 13. When the solution is filtered by the filter barrel 12, various impurities will accumulate on the inner wall of the filter barrel 12, causing the filter holes on the filter barrel 12 to be blocked and the filtration rate to slow down. At this time, the electric telescopic rod 7 can be started, so that the rear end of the electric telescopic rod 7 drives the rack 5 to push forward. At this time, the right end of the rack 5 meshes with the gear 4 to rotate clockwise, so that the gear 4 drives the extrusion plate 9 to rotate inside the filter barrel 12 through the connecting rod 8 to clean, driving the impurities to the sunken structure of the filter barrel 12, thus avoiding the frequent blockage of the filter barrel 12 and facilitating the filtration of the solution. And the design of the double-edged blades 10 is convenient for cutting the colloidal impurities, improving the cleaning effect of the device. And when the electric telescopic rod 7 contracts, it can drive the gear 4 to rotate counterclockwise, making the extrusion plate 9 sweep in the opposite direction, which is convenient for use.

The special-shaped parts can be customized according to the descriptions in the specification and the attached drawings. The specific connection methods of each part all adopt the conventional means such as bolts, rivets, welding, etc. that are mature in the prior art.

In addition, the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
