[0002] With the continuous development of society and the continuous progress of science, metal products can be seen everywhere in our daily life. Therefore, in order to meet people's demand for metal materials in life, the metallurgical industry is developing more and more rapidly. Usually in metallurgical plants, there is a lot of dust floating in the air, which will have a certain impact on the health of the workers in the plant. Usually, large-scale dust removal is carried out in the plant every once in a while. The content of gold in the ore is extremely low. In order to extract gold, the ore needs to be crushed and ground and the beneficiation method is used to pre-enrich or separate the gold from the ore. Gravity separation and flotation are more commonly used in gold beneficiation. Gravity separation occupies a very important position in the production of placer gold. Flotation is a beneficiation method widely used in rock gold mines. About 80% of rock gold mines in my country use this method to select gold, and the level of beneficiation technology and equipment has been greatly improved.

[0003] In the prior art, the scraper dust collection device uses a ventilation dust-proof net to filter and block the dust in the wind during the dust collection process. However, the dust can easily clog the dust-proof net, affecting the flow of wind and the collection of dust. In addition, the existing scraper dust collection device is not convenient for adjusting the position of dust absorption and has poor practicality. A scraper dust collection device is now invented to solve the above problems. Utility Model Content
