Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, a battery slurry sieving device comprises a sieving tank 4, wherein a feeding port 1 is arranged at the upper part of the sieving tank 4, a discharging port 2 is arranged at the lower part of the sieving tank 4, and the feeding port 1 is connected with a discharging port of a stirrer through a connecting pipeline; a sieving device is arranged in the middle of the sieving tank 4 and comprises a sieving disc 6, a rotating shaft 3 and rotating fins 5, a screen is arranged in the sieving disc 6, the middle of the sieving disc 6 is convex, and grooves are formed in the periphery of the sieving disc 6; the rotating shaft 3 is connected with the rotating wings 5, the rotating wings 5 are located above the sieving disc 6, the rotating shaft 3 is connected with the motor, the rotating shaft 3 is driven by the motor to rotate, the rotating shaft 3 rotates to drive the rotating wings 5 to rotate, the rotating wings 5 rotate to drive materials on the sieve screen to rotate and sieve, and larger particles can be extruded into grooves around the sieving disc 6 in the rotating process of the rotating wings 5, so that the blocking of the large particles is reduced.

The sieve tray 6 is internally provided with a sieve mesh of 100-200. The more the screen meshes are arranged in the screening tray 6, the smaller the aperture is, the finer the screened pulp is, but for this reason, the more the screen meshes are pursued at one glance, the smaller the aperture is, because the finer the aperture is, the greater the risk of blockage in the screening process is, which is not favorable for the efficiency of screening the whole pulp, and also easily damages the screening device, preferably, the screen meshes arranged in the screening tray 6 is 150.
