The return belt cleaning device is used to remove materials adhering to the return belt of a belt conveyor, effectively improving the working environment and extending the belt's service life. The following are introductions to several typical products:
Type A Return Belt Cleaning Box

- Product Composition: Consists of an adjustment device, atomizing cleaner, belt pressing roller, tungsten carbide scraper cleaner, etc.
- Working Principle: Installed at the return section of the belt conveyor head, it removes adhered materials from the belt surface through steps such as atomizing cleaning, scraping, and dewatering, with regular automatic flushing. Wastewater is drained away by the sewage collection box.
- Product Features: Suitable for belt conveyors with speeds up to 6m/s, integrates multiple functions, thoroughly removes adhered materials, and is equipped with a fine-tuning device to ensure smooth belt operation and convenient maintenance.
- Product Types: Divided into dry and wet types. Wet cleaners clean the belt through steps such as atomizing infiltration and scraper separation; dry cleaners use friction to rotate the cleaning brush roller, brushing off adhered materials on the return belt.
- Working Principle: Wet cleaners are interlocked with the belt conveyor signals, starting the booster pump, solenoid valve, etc., to clean the belt through steps such as spraying, cleaning, and dehumidifying; dry cleaners use springs to lift the drive roller, bringing the cleaning brush roller into contact with the return belt, using friction to drive the cleaning brush roller for rotation and cleaning.
- Product Features: Complete specifications and models, wide applicability. Wet cleaners use spiral sewage discharge to reduce maintenance, while dry cleaners are power-free, energy-saving, and environmentally friendly.
Type B Return Belt Cleaning Device:

- Product Composition: Includes a box body, pressure roller group, water spray system, cleaning system, and drying system.
- Working Principle: When the belt conveyor starts, the cleaning device is interlocked with the belt conveyor signals. The return belt is pressed down to fully contact the water distribution softening roller and the cleaning system scraper. The water spray system sprays purified water to soften adhered materials, which are then removed by the cleaning system. Sludge and water are collected by the collection box and discharged through the spiral sewage discharge system.
- Product Features: Achieves 98% cleaning efficiency for adhered materials on the return belt surface, solving environmental pollution issues caused by material carryback on the return belt.

Application Scenarios of Belt Washing Cleaning Box
Widely used in industries such as coal mines, power plants, ports, chemicals, and metallurgy, it addresses needs like coal spillage on return belts in coal mines, coal dust pollution in power plants, cross-contamination in ports, and corrosion resistance in chemical industries. It is also suitable for special scenarios such as oil stain cleaning on airport conveyor belts.
