Technical Field

The invention relates to the technical field of lithium battery material conveying, in particular to a large-particle material conveying pump.

Background

As a known internal material for a lithium battery, a suspension of particles or powder such as lithium cobaltate, lithium manganate, or lithium iron phosphate is generally used as a raw material. In the manufacturing process of the battery, a peristaltic pump is usually used as a power conveying device, but the working principle of the peristaltic pump is that the material is conveyed by repeatedly extruding and loosening the elastic rubber tube, when the material contains large hard particles, the elastic rubber tube is abraded by the material due to extrusion, and the service life is short.

Of course, some enterprises also adopt the homogenizing pump to carry, but the existing homogenizing pump has a relatively simple and crude structure, and the functional components are a rotor (fluted disc) driven by a motor and a stator fixed in the cylinder. Because they have the functions of grinding, shearing, emulsifying and feeding, the grinding effect is poor (if a fluted disc with dense vertical teeth is adopted, the feeding speed is very slow, and if a fluted disc with sparse vertical teeth is adopted, a large amount of large particles which are not crushed exist), and the production requirement can be met only by repeatedly homogenizing for many times.
