Description

Technical Field

[0002] Mullite, as a high-quality refractory material, has a high melting point, high strength and excellent thermal shock resistance. It is widely used in metallurgy, ceramics and glass industries. In the application and production process of mullite, it is often necessary to grind and refine the mullite raw material.

[0003] CN216396554U discloses a grinding device for mullite raw materials, including a support frame, power cord, drive module, rotating shaft, ball mill cylinder, observation window, feed pipe, and pushing mechanism. This invention features a pushing mechanism at the upper end of the feed pipe. A first motor, when energized, drives a gear to rotate clockwise, causing the gear to move a rack to the left, thereby moving a brushing mechanism towards the inside of the feed pipe to brush off material adhering to the side wall, thus preventing material residue. A second motor, also energized, drives a turntable to rotate inside a receiving plate, causing the turntable to rotate a brush head to scrape off material, further preventing material adhesion. However, this device relies on the collision between the iron ball and the mullite raw material for grinding and crushing, resulting in a relatively simple grinding method and affecting the grinding efficiency. Therefore, improvements are needed. Utility Model Content

[0020] The specific implementation method is as follows: by setting up the cleaning component 7, the fixed groove seat 704 is driven to revolve by the rotation of the processing roller 1, which in turn drives the transmission gear 707 to rotate. The two screw seats 702 are driven to move synchronously through the first reciprocating screw 706, which ultimately drives the two scraping plates 701 to continuously and bidirectionally scrape and clean the outer surface of the processing roller 1. This effectively removes the mullite powder attached to the surface of the processing roller 1, prevents clogging, significantly improves grinding efficiency and product quality, and reduces the frequency of downtime for cleaning, thus reducing maintenance costs.

Furthermore, the cooperation between the moving plate 806 and the second reciprocating screw 801 can drive the moving plate 806 to move back and forth along the length of the processing drum 1, increasing the crushing range and improving the grinding efficiency of the mullite raw material. During the crushing and grinding process of mullite raw materials, the rotation of the processing drum 1 drives the fixed groove seat 704 to rotate. The fixed groove seat 704 drives the transmission gear 707 to revolve around the fixed gear ring 703, causing the transmission gear 707 to rotate. The transmission gear 707 drives the first reciprocating screw 706 to rotate. The two first reciprocating screws 706 drive the two screw seats 702 to move synchronously. The two screw seats 702 drive the two scraper plates 701 to move against the outer surface of the processing drum 1 and scrape it, which can clean the mullite powder in the filter holes and prevent the filter holes from clogging.
