How to choose a belt conveyor cleaner?

The cleaner has an important role on the conveyor. It can promptly and quickly remove the residual material sticking to the conveyor belt to prevent it from being brought back to the return branch, causing dirt on the surface-increasing roller and return roller, and causing belt wear , Deviation, etc., to avoid the danger of casualties caused by manual removal of attachments. This article analyzes 3 belt conveyor cleaners with different structures, so that you can make correct and appropriate selections.

1. Scraper cleaner

The scraper cleaner uses the gravity of the counterweight or the elastic force of the boom to make the scraper fixed on the boom come into close contact with the working surface of the conveyor belt to remove residual materials on it. According to the number of scrapers, it can be divided into single, double and multiple scrapers. Scrapers are made of rubber, cemented carbide, ceramics, etc.

2. Rotary cleaner

The rotary cleaner is composed of an independently driven main shaft and a hard brush or scraper mounted on it. The hard brush is made of nylon, etc., and the scraper is made of rubber or hard alloy.

The high-speed rotation direction of the rotary cleaner is opposite to the running direction of the conveyor belt (the linear speed of the brush or scraper is not less than 10m/s). The brush or scraper not only cleans the conveyor belt directly, but also because of its high speed. A low pressure area is formed at the front to enhance the cleaning effect.

This kind of cleaner is often installed at the head and tail rollers of the conveyor to clean powdery granular materials.

3. Water spray cleaner

The water spray cleaner is suitable for conveying materials that are not afraid of dampness, and the water source is sufficient and there is a sewage system. For example, the transportation of poured dam concrete, the dredging of river channels, and the sludge transportation in hydraulic engineering can use water spray cleaners. The conveyor belt is cleaned by pressurized water, and the effect is very good.
