Crushing device convenient to clean and cleaning method

Abstract

The invention discloses a crushing device convenient to clean and a cleaning method. The crushing device comprises a base, a trolley and a crushing device. The crushing device comprises a lower crushing box, connecting plates, a fixed ring, a first corrugated pipe rubber ring, an upper crushing box, a rotating ring, a second corrugated pipe rubber ring, a rotating assembly and a gear. The top of the lower crushing box is of an open structure. The connecting plates are symmetrically and vertically arranged on the two sides of the top of the lower crushing box. The fixed ring is fixed between the connecting plates. The first corrugated pipe rubber ring is arranged in the fixed ring. The upper crushing box penetrates through the fixed ring and extends into the lower crushing box, and the bottom of the upper crushing box is of an open structure. The rotating ring is fixed to the top of the upper crushing box. The second corrugated pipe rubber ring sleeves the rotating ring. The rotating assembly is arranged on the lower crushing box. The gear is arranged on an outer wall of the rotating ring. Self-rotating of the upper crushing box is carried out in the lower crushing box, a certain rotating speed and slight fluctuation are generated, and therefore the possibility that crushed materials are stacked on an inner wall is fundamentally reduced.

Description

technical field [0001] The invention belongs to the technical field of crushing devices, and in particular relates to a crushing device and a cleaning method that are easy to clean. Background technique [0002] In the production process of lithium battery cathode materials, such as lithium cobalt oxide, lithium manganese oxide, ternary materials, lithium nickel cobalt oxide and other materials, it is necessary to crush the agglomerated materials after roasting, and the crushing is divided into coarse crushing and fine crushing. There are two stages of crushing, and the roller crusher is the equipment used in the stage of coarse crushing of materials. Because the material is relatively sticky, part of the powder after crushing will stick to the inner wall of the crushing device, and because of the large volume of the crushing device, it becomes very troublesome to clean the inner wall; if the inner wall of the crushing device is not Timely cleaning will directly affect the ...

AI Technical Summary

Problems solved by technology

Because the material is relatively sticky, part of the powder after crushing will stick to the inner wall of the crushing device, and because of the large volume of the crushing device, it becomes very troublesome to clean the inner wall; if the inner wall of the crushing device is not Timely cleaning will directly affect the purity of the crushed material

[0003] In the prior art, a rotatable scraper is added to the inner wall of the crushing device, and the scraper scrapes dirt from the inner wall of the crushing device. However, if the distance between the scraper and the inner wall is too close in this structure, it will If the inner wall is damaged, there is a certain distance between the scraper and the inner wall, so it cannot be guaranteed to be cleaned, and if the inner wall is cleaned directly in the later stage, it cannot be guaranteed to be cleaned because some corners are difficult to reach when the device is large enough
