The Secret of Longevity of Belt Conveyor - Cleaning Device

The Belt cleaner, also known as the scraper, is an auxiliary component on the belt conveyor and is generally installed at the head and tail of the belt conveyor; If the cleaner is placed at the head of the conveyor belt, it is mainly used to scrape off the sticky materials and debris on the front of the conveyor belt; If the cleaner is placed at the rear of the conveyor belt, it is mainly used to scrape off accumulated materials and debris on the back of the conveyor belt, to prevent them from being carried into the tail drum of the machine.

Application of sweeper: The sweeper is one of the main components of the belt conveyor. In order to prevent dust during material transportation and meet production process requirements, most of the transported materials need to maintain a certain moisture content. For example, in many power plants, the moisture content of coal conveyor belts is about 12%, which will inevitably cause water containing materials to adhere to the belt. If not cleaned, it will continuously scatter during belt operation and return roller collision. The poor cleaning effect of the belt conveyor cleaner can lead to the following defects: a. There is too much residual material under the conveyor belt, causing a harsh on-site environment, which can easily harm the physical health of on-site operators, increase the labor intensity of maintenance personnel, and easily cause accidents and injuries to on-site personnel; b. Due to the accumulation of materials on the conveyor belt, it can cause friction between the return rollers and rollers, greatly reducing the service life of the conveyor belt, rollers, and return rollers, and increasing cost consumption; Due to excessive material leakage, the conveying efficiency of the belt is reduced.

In addition, during the material conveying process of the belt conveyor, if residual attached materials enter the bearing seat of the drum or roller, it will accelerate bearing wear, tear and roughen the surface glue of the conveyor belt due to the adhesion of materials on the surface of the drum or roller, accelerating the wear and damage of the conveyor belt; If the material is diverted towards the drum at the tail of the belt conveyor or adheres and clumps on the surface of the vertical tension drum, it will cause the conveyor belt to deviate, increase the wear of the conveyor belt, and even tear the rubber layer of the drum, causing serious consequences. If the cleaning device is effective, the service life of the rollers, conveyor belts, rollers, etc. can be extended; So the cleaning ability of the cleaner plays a crucial role in improving the operating efficiency and reliability of the belt conveyor, reducing equipment failure rates, and reducing maintenance costs.
