[0018] Compared with the prior art, the utility model has the following beneficial effects: the lithium sulfate solution anti-clogging precision filter:

[0019] 1. The anti-clogging mechanism solves the problem of solid precipitation in the lithium sulfate solution clogging the filter plate. The lithium sulfate solution to be filtered is poured into the outer shell, and the adsorption plate will adsorb most of the solid precipitation, but a small amount of solid precipitation will still fall onto the filter plate. As the use time continues to increase, a large amount of solid precipitation will gradually accumulate on the surface of the filter plate, slowing down the filtration rate of the lithium sulfate solution and even clogging the filter plate. Under the action of the motor, the piston moves up and down repeatedly on the inner wall of the outer shell. During the up and down movement of the piston, the liquid between the filter plate and the piston will be squeezed upward, and most of the liquid will flow out from the guide tube, and a small part of the liquid will pass through the filter plate upward, thereby clearing the solid precipitation blocking the surface of the filter plate, thereby preventing clogging. This mechanism prevents precipitation blockage while filtering, and indirectly improves the filtration efficiency.

[0020] 2. The adsorption mechanism facilitates the removal of solid precipitation in the lithium sulfate solution. When the motor is started, the motor drives the transmission shaft 1 to rotate through the transmission belt. During the rotation of the transmission shaft 1, the meshing gear 1 and the meshing gear 2 rotate at the same time. The transmission shaft 2 fixedly connected at the lower end of the meshing gear 2 rotates on the rotating frame at the same time. During the rotation of the rotating frame, the lithium sulfate solution is stirred to suspend the precipitation in the lithium sulfate solution, which facilitates the adsorption cotton in the adsorption plate to adsorb the precipitation. The adsorption plate absorbs most of the precipitation and increases the filtration rate. When the adsorption cotton in the adsorption plate is saturated and needs to be replaced, the adsorption plate is removed from the slot, and then replaced with a new adsorption cotton, and the adsorption plate is reinserted from the upper end of the slot.
