Description

Automatic clear polyurethane sweeper

Technical Field

The utility model relates to a conveyor belt corollary device, in particular to a self-cleaning polyurethane sweeper.

Background

In the process of conveying materials by the belt conveyor, if the residual adhering materials enter the roller or the roller bearing seat, bearing abrasion can be accelerated, the surface of the roller or the roller is stuck with the materials, the materials can be torn and the surface rubber of the conveying belt can be roughened, and the abrasion and the damage of the conveying belt can be accelerated. If materials are attached to and caked on the surfaces of the turnabout rollers or the vertical tensioning rollers at the tail of the belt conveyor, the conveying belt can be deviated, the abrasion of the conveying belt is increased, even the rubber coating layer of the rollers is torn, and serious consequences are caused. The cleaning device has good effect, and the service life of the carrier roller, the conveying belt, the roller and the like can be prolonged; therefore, the cleaning capability of the cleaner plays a significant role in improving the operation efficiency and reliability of the belt conveyor, reducing the equipment failure rate and reducing the maintenance cost.

A polyurethane cleaner is a cleaner whose tool bit is made of polyurethane material, and is widely used in the industry due to the stable physicochemical properties of polyurethane. The polyurethane cleaner is mainly used for cleaning the sticky materials and sundries on the front and back surfaces of the belt. The sweeper has a non-negligible function on a conveyor, and production conveying equipment of enterprises such as coal mines, electric power, steel, petrochemical enterprises and the like all depend on the sweeper to clean.
