Problems solved by technology

[0003] As we all know, the working principle of the peristaltic pump is to pump the fluid by alternately squeezing and releasing the elastic delivery hose of the pump, but the raw material powder of the lithium battery contains a large amount of particulate matter with relatively high hardness, and the peristaltic pump is easily worn
In addition, during the extrusion process of the suspension (liquefied powder), solid particles tend to accumulate in the narrow part of the elastic conveying hose, and after the elastic conveying hose is released, it is easy to form a periodic sudden change in the concentration of the material in a local area, which is not conducive to Assembly line production

Abstract

The invention relates to the field of lithium battery processing equipment, in particular to a lithium battery material powder conveying pump. The lithium battery material powder conveying pump comprises a power mechanism, a transmission mechanism and a pump body. The power mechanism comprises a motor and a base. The transmission mechanism comprises a bearing pedestal, a coupler, a main shaft and two sets of deep groove ball bearings. The pump body comprises an outer barrel, a mechanical seal, an impeller and a barrel rear cover. The overall structure in a grinding machine form is matched with the impeller for feeding, liquid powder can be continuously conveyed, materials are finer and more uniform through stirring and shearing of the impeller in the conveying process, and durability of the whole structure is guaranteed.

Description

technical field [0001] The invention relates to the field of lithium battery processing equipment, in particular to a lithium battery material powder delivery pump. Background technique [0002] In the process of lithium battery processing, equipment such as peristaltic pumps are needed to realize the transportation of powder materials. For example, a Chinese patent on a method for recovering nano-iron phosphate from lithium iron phosphate batteries, patent No. 201710567598.6 records: add lithium iron phosphate powder to dilute hydrochloric acid solution while stirring, and pass hydrogen peroxide and suspension through a peristaltic pump at the same time Add dropwise to the three-necked flask reactor. [0003] It is well known that the working principle of the peristaltic pump is to pump fluid by alternately squeezing and releasing the elastic delivery hose of the pump. However, the raw material powder of lithium batteries contains a large amount of particulate matter with ...
