Description

Sealing device in sand and mud

Technical Field

The utility model relates to a sand washer technical field specifically is a sealing device in silt particle.

Background

The sand washer is a washing device for artificial sand (including natural sand). The sand washer is widely used for washing and selecting materials in industries such as gravel fields, mines, building materials, traffic, chemical engineering, water conservancy and hydropower, concrete mixing stations and the like. The rolling devices installed in the water tank of the existing spiral sand washer all use bearing seats as many as others, and the sealing devices in the existing sand and mud are sealed by sealing rings, so that the existing sand and mud washer can be damaged only after about 3 months in the production process, and the abrasion of the shaft is very fast, so that the existing sand and mud washer needs to be replaced, and the production cost is high.
