Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction of coal washing machines, in particular to a dust reduction spraying device for coal washing machines. Background Technique

[0002] Coal washing is to separate raw coal with different components and specific gravities into different grades through the impact of water flow, remove dust and waste rock, and reduce the ash content and sulfur content. Coal washing is an essential link in coal processing. The coal after washing is called clean coal. Through coal washing, not only can the environmental protection purpose be achieved, but also the utilization rate of coal can be improved, etc. When processing coal, special coal washing machines are usually used for coal washing operations. However, during the coal washing process, a large amount of dust is often generated, seriously polluting the working environment and affecting the health of workers. Therefore, corresponding dust reduction spraying measures need to be taken to inhibit dust pollution and improve the quality of the working environment.

[0003] For example, a fixed-rail dust isolation and reduction device for coal mining machines disclosed in the authorized announcement number CN216566675U includes a lifting spraying dust reduction frame unit and a retractable dust isolation unit fixedly installed at the lower end of the lifting spraying dust reduction frame unit. One end of the curtain body is connected to the roller shaft, and the two ends of the roller shaft are movably sleeved with coil springs. When in use, by pulling up the fixing rod, the curtain body is pulled out of the box body, and the fixing rod is hung on the hook strip welded at the lower end of the water storage rod through the hanging groove for dust isolation use. When not in dust isolation, the fixing rod is removed from the hook strip, and the coil spring resets to drive the roller shaft to rotate, so that the curtain body is wound on the roller shaft for storage. The structure is simple and convenient to use, and can effectively reduce the damage of the curtain body. However, this utility model lacks convenient lifting and spraying angle adjustment measures, which is not convenient to ensure the operation flexibility of this utility model. Therefore, we propose a dust reduction spraying device for coal washing machines, which solves the problems of lifting and angle adjustment of this utility model, facilitates the operators to flexibly adjust the working surface of the device according to different working environments, and improves the practical effect of the device and the operation convenience of the staff.
