Dust preventing structure used during quartz sand grinding

Abstract

The invention discloses a dust preventing structure used during quartz sand grinding. The dust preventing structure comprises a grinding box, a bearing plate, a motor, a rotating shaft and a dust preventing assembly, wherein the dust preventing assembly is arranged outside the rotating shaft, the rotating shaft is arranged on the motor, the motor is fixedly inserted on the bearing plate, the bearing plate is fixedly arranged in the grinding box, the dust preventing assembly comprises a first sleeve groove and a second sleeve groove, a through hole is formed in the joint between the first sleeve groove and the second sleeve groove, a first dust preventing plate is fixedly arranged on the side wall of the first sleeve groove, the upper end of the first dust preventing plate is fixedly arranged on the lower end surface of the bearing plate, and a second dust preventing plate is fixedly arranged on the outer side wall of the second sleeve groove. According to the dust preventing structure, the dust preventing assembly is added, the dust preventing assembly can not only achieve the detachable effect of the rotating shaft, but also achieve the effective dust preventing effect; and in the dust preventing structure, the dust preventing assembly can not only achieve the convenient disassembly of the rotating shaft, but also realize effective protection of the motor.

Description

technical field [0001] The invention relates to the technical field of quartz sand grinding equipment, in particular to a dust-proof structure for quartz sand grinding. Background technique [0002] Quartz sand is a hard, wear-resistant, and chemically stable silicate mineral. Its main mineral component is SiO2. The color of quartz sand is milky white, or colorless and translucent. Shaped fracture, grease luster, density 2.65, bulk density (1.6-1.8 for 1-20 mesh), 1.5 for 20-200 mesh, its chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid, slightly soluble In KOH solution, the melting point is 1750°C. [0003] In order to meet the processing requirements, it is necessary to grind the quartz sand into powder. During the process of grinding into powder, it is necessary to install a dust-proof structure to prevent dust from entering the drive equipment and affecting the equipment. However, the existing dust-proof device is set On the rotati...

Problems solved by technology

[0003] In order to meet the processing requirements, it is necessary to grind the quartz sand into powder. During the process of grinding into powder, it is necessary to install a dust-proof structure to prevent dust from entering the drive equipment and affecting the equipment. However, the existing dust-proof device is set On the rotating shaft, there is a problem that it is inconvenient to disassemble the rotating shaft. In order to solve the above problems, the present invention proposes a dust-proof structure for quartz sand grinding.
