Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to a tiltable automatic ball mill cleaning device. Background Art

[0002] The wet ball milling process is a raw material processing technology currently adopted by most cemented carbide factories in my country. The main equipment used in this process is a tilting wet ball mill. The wet ball milling process refers to placing the material, solvent, and grinding body in the cylinder of the tilting wet ball mill. The cylinder rotates, driving the grinding body in the cylinder to move and grind the material while mixing the material evenly. The inner wall and grinding body will be attached with the material from the previous ball milling. During the next ball milling, it will be mixed with the new material, causing the material to become dirty. Therefore, after each ball milling, the grinding body and the inner wall of the cylinder need to be manually cleaned to ensure that there is no residue.

[0003] At present, there are two ways to clean the tilting ball mill in the cemented carbide industry:

[0004] 1. Manual cleaning: The ball mill is cleaned by repeatedly injecting and pouring water. Specifically, when cleaning, inject an appropriate amount of clean water into the ball mill, then start the ball mill to grind empty, so that the materials attached to the grinding body and the inner wall can be separated into the water, and then pour out the waste water in the ball mill. Repeat the steps of injecting clean water-milling empty-pouring waste water until the waste water poured out is clear and transparent, which means that the ball mill has been cleaned. Depending on the nature of the material, the number of cleanings varies from five to eight times. This cleaning process normally takes 40 to 50 minutes. This work will take up a lot of time in daily production and affect the work efficiency. This cleaning method is currently widely used and requires manual water injection and pouring operations, but the cleaning process is cumbersome, time-consuming and labor-intensive.

[0005] 2. Guantian wet mill (newly launched by Zhuzhou Changjiang Cemented Carbide Equipment Co., Ltd.) is a wet mill with cleaning function. This ball mill adopts PLC control and cleans the ball mill by unloading and repeatedly adding water to wash the balls. However, this cleaning method requires replacing the ball mill with a new one, which is costly and cannot be implemented on the basis of the existing ball mill. Summary of the Invention

[0006] In order to overcome the above-mentioned shortcomings, the purpose of the present utility model is to provide a tiltable automatic ball mill cleaning device, which flushes the ball mill cylinder through a cleaning mechanism.
