Abstract

The invention relates to the technical field of dust removal equipment, and provides a dust removal cover, which includes a pipe body, the pipe body surrounds the circumferential direction of the roller body, and the central axis of the pipe body coincides with the central axis of the roller body. The pipe body has an air inlet end and an air outlet end. The bottom of the air inlet end of the pipe protrudes outward along the direction away from the air flow to form a deflector for surrounding the surface of the pole piece. According to the structural characteristics of the pipe body, the dust cover of the present application surrounds the circumference of the roller body to adapt to the arc-shaped structure of the pole piece and the movement characteristics of the rotation around the axis of the roller body, so that the gap between the bottom of the air inlet end of the pipe body and the pole piece The air leakage gap is reduced to ensure the contact area between the two, so that dust particles can enter the pipe body as much as possible. Furthermore, the gap is further blocked by using the deflector, that is, the distance between the gaps is further reduced, and the dust on the pole pieces is guided by the deflector and quickly and intensively enters the tube body under the positive pressure wind force , the dust removal efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment, in particular to a dust removal hood. Background technique [0002] The ternary cell is a cell with a ternary positive electrode material whose positive electrode material is nickel-cobalt lithium manganate or nickel-cobalt aluminum oxide. The battery with ternary material as the positive electrode is more safe than the lithium cobalt oxide battery. With the promotion and popularization of electric vehicles and hybrid vehicles, the development of ternary batteries with high endurance and excellent safety performance has become a difficult problem for various enterprises. [0003] In the production process of ternary cells, it is unavoidable that the separation film is ruptured and the positive and negative electrodes are short-circuited due to foreign matter such as particles and metal chips on the surface of various pole pieces. Therefore, it is very necessary to dedust the pole...
