A crushing device and cleaning method for easy cleaning

Abstract

The invention discloses a crushing device and a cleaning method that are easy to clean, including: a base, a trolley and a crushing device; wherein, the crushing device includes: a lower crushing box with an open top; symmetrically and vertically arranged on the lower The connecting plates on both sides of the top of the crushing box; the fixing ring fixed between the connecting plates; the first bellows rubber ring arranged inside the fixing ring; passing through the fixing ring and extending to the lower crushing The upper crushing box inside the box and the bottom is an open structure; the rotating ring fixed on the top of the upper crushing box; the second bellows rubber ring sleeved outside the rotating ring; the rotating ring installed on the lower crushing box Assemblies; and gears arranged on the outer wall of the rotating circle; the upper crushing box of the present invention rotates inside the lower crushing box to produce a certain speed and slight fluctuations, which fundamentally reduces the possibility of crushed materials accumulating on the inner wall .

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
