Description

Technical Field

[0001] The utility model relates to the technical field of quartz raw material filtering equipment, in particular to a rapid grading and screening device for washing and purifying quartz sand. Background Art

[0002] The rapid development of modern science and technology has put forward higher purity requirements for quartz, a basic raw material. It is recognized worldwide that high-purity and ultra-high-purity quartz raw materials are an important foundation for today's high-tech products and a necessary condition for the sustainable development of a country's high-tech.

[0003] After searching, it was found that the announcement number is CN213855704U, and the name is a quartz sand rapid grading and screening device. The application proposes that when the existing screening machine is in use, the quartz sand particles are easily stuck in the mesh holes in the drum screen. Once stuck, it is difficult to clean, which makes the drum screen unable to achieve the screening effect, and due to the different diameters of the drum, the quartz sand on its surface is more difficult to clean. By installing a separation device, the quartz sand on the drum surface can be cleaned. When the drum rotates, it drives the needle hair wheel connected to the drum surface to rotate. The needle hair on the surface of the needle hair wheel will poke the quartz sand stuck on the drum surface into the inside of the drum, thereby enhancing efficiency and practicality. However, when the application is actually used, the quartz sand inside the drum is difficult to remove and needs to be unloaded manually. Its continuity and work efficiency are seriously affected, and further improvements can be made. Secondly, once the needle hair on the surface of the needle hair roller is completely damaged, it is difficult to replace, which affects the convenience of inspection and maintenance, and further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
