The belt water wash cleaning box is a device used to remove materials adhered to the return belt of a belt conveyor. It effectively improves belt cleanliness, extends the belt's service life, and enhances the working environment. Below is a related introduction:
Components
It generally consists of a water wash cleaning box body, a belt stabilization system, a spray system, a cleaning system, an air-drying system, a sewage discharge system, a control system, and more.
Working Principle
When the belt conveyor starts, the cleaning box interconnects with the conveyor's signal. The return belt is pressed down to ensure full contact with the water distribution softening roller and the cleaning system's scraper. The solenoid valve opens, and purified water is evenly sprayed onto the belt surface through nozzles to soften adhered materials. The cleaning system's scraper then removes them, and the sludge and water are collected by the collection box and discharged through the spiral sewage discharge system.
Product Features of the Conveyor Belt Return Water Wash Cleaning Box
- Excellent Cleaning Effect: Achieves over 98% cleaning efficiency for adhered materials on the return belt surface, thoroughly resolving environmental pollution caused by material carryback on the return belt.
- Belt Protection: Some cleaning boxes use high-quality scraper materials, such as carbide scrapers, which do not damage the belt and have a long service life, extending the belt and idler lifespan by approximately 30%.
- Intelligent Control: Interlocked with the belt conveyor signal for synchronized start and stop, supports automatic/semi-automatic mode switching, and can be equipped with remote control ports to connect with the central control room for intelligent management.
- Strong Adaptability: Can be customized based on belt speed, material characteristics, water supply conditions, etc. The drainage funnel can also be customized according to on-site needs, making it suitable for various working conditions.
Application Scenarios
Widely used in industries such as coal mines, power plants, ports, chemicals, and metallurgy. It addresses needs like coal carryback in 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.

The belt cleaning box is a highly efficient cleaning device specifically designed for various belt conveyor systems. It effectively removes residual dust, particles, and adhered materials from the conveyor belt surface and is widely used in material handling processes across industries such as mining, cement, power, chemicals, and ports.
Core Advantages
1. High-Efficiency Cleaning: Utilizes highly wear-resistant polyurethane scrapers or alloy blades that closely fit the belt surface, achieving a removal rate of over 95%, significantly reducing material waste and environmental pollution.
2. Intelligent Adjustment: Equipped with automatic compensation devices (spring/hydraulic) to adjust scraper pressure in real-time, ensuring constant contact with the belt and eliminating the need for frequent manual adjustments.
3. Long Service Life: Scrapers are made of special composite materials that are impact-resistant and wear-resistant, offering a service life 3-5 times longer than ordinary rubber scrapers, greatly reducing replacement frequency and maintenance costs.
4. Eco-Friendly and Low Consumption: Features a closed structure design that effectively suppresses dust dispersion. When combined with an optional spray system, it enables clean production and meets environmental requirements.
5. Easy Installation: Modular design compatible with various belt conveyors (belt widths 500-2200mm), supporting multiple installation methods such as horizontal and inclined setups. Deployment can be completed in 1-2 hours.
Applicable Scenarios for Conveyor Belt Return Cleaning Box
1. Mining Industry: Removes sticky and wet materials like coal and ore.
2. Cement Plants: Cleans residual cement clinker and fly ash.
3. Ports and Terminals: Addresses material carryback issues with bulk goods like grains and fertilizers.
4. Waste Treatment: Removes stubborn stains from conveyor belts.
