Crushing device with convenient cleaning performance and cleaning method thereof

Abstract

The invention discloses a crushing device with convenient cleaning performance and a cleaning method thereof. The crushing device comprises a base, a cart and a crushing device body, wherein the crushing device body comprises a lower crushing box, connecting plates, a fixing 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 an open structure, the connecting plates are symmetrically and vertically arranged on the two sides of the top of the lower crushingbox, the fixing ring is fixed between the connecting plates, the first corrugated pipe rubber ring arranged inside the fixing ring, the upper crushing box penetrates through the fixing 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 at the top of the upper crushing box, the second corrugated pipe rubber ringis connected to the outer surface of the rotating ring in a sleeving mode, the rotating assembly is arranged on the lower crushing box, and the gear is arranged on the outer wall of the rotating ring. According to the crushing device, the upper crushing box rotates inside the lower crushing box to generate a certain rotating speed and fine fluctuation, so that the possibility that crushed materials are accumulated on the inner wall is fundamentally reduced.

Description

[0001] This patent is a divisional application. The information of the original application is as follows, title: A crushing device and cleaning method for easy cleaning, application number: 2019102034151, application date: 2019-03-18. technical field [0002] The invention belongs to the technical field of crushing devices, and in particular relates to a crushing device and a cleaning method thereof which are convenient for cleaning. Background technique [0003] In the production process of lithium battery cathode materials, such as lithium cobalt oxide, lithium manganate, ternary materials, lithium nickel cobalt oxide and other materials, it is necessary to pulverize the agglomerated materials after roasting, and the pulverization is divided into coarse grinding and fine grinding. There are two stages of crushing, and the roller crusher is the equipment used in the coarse crushing stage of the material. Because the material is relatively sticky, some of the powder after...

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

[0004] 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
