Description

Sweeper for belt conveying device

Technical Field

The utility model relates to a band conveyer technical field especially relates to a sweeper for belt conveyor.

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 sweeper is a device which is arranged at the head of the coal conveying belt or the return belt and is used for removing coal stuck on the belt and preventing the return belt from spilling and falling coal and raising dust. 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.

At present, in the existing traditional sweeper in the market of China, the sweeping sheet is made of polyurethane, the hardness is high, and the sweeping sheet has two defects:

(1) when sundries exist in the coal flow, the sundries are easily clamped between the sweeper and the belt, the belt is easily damaged, and the service life of the belt is influenced.

(2) The water content is higher in the coal stream, and when the coal quality is more glutinous, traditional sweeper cleans the effect relatively poor, can't effectively clear away and glue the coal that glues on the belt surface.

Therefore, a belt cleaner made of a soft material is planned to be researched, foreign matters are not easily jammed, and the cleaning effect is greatly enhanced when the belt cleaner faces sticky coal.
