The working principle of self-cleaning rubber conveyor belts primarily relies on self-cleaning devices integrated into the conveyor system. These systems automatically remove materials, dust, or impurities adhering to the belt surface through methods such as physical contact, fluid flushing, or kinetic energy drive.
Adhesive Roller Adsorption (Friction-Driven)
- Structure: An adhesive roller is installed on the conveyor frame, with a spring-loaded telescopic rod applying pressure to ensure tight contact between the roller and the belt surface.
- Working Mode: The friction generated by the running conveyor belt drives the adhesive roller to rotate, and the adhesive film on its surface continuously picks up impurities from the belt.
- Maintenance: Cleaning is completed by periodically peeling off and replacing the adhesive film.
- Advantages: Simple structure, no extra power required, and suitable for light dust or fine particles.
Scraper/Brush Mechanical Cleaning
- Alloy Rubber Cleaners: Hard alloy blade heads scrape off stubborn materials, while elastic rubber conforms to the belt surface to ensure cleaning effectiveness.
- Rubber Brush Cleaners: Composite bristles of nylon and elastic rubber brush off adhered materials through friction. They adapt to slight belt misalignment without damaging the belt surface.
- Passive Rotary Brush Cleaners: Utilize the friction from the belt's movement to drive the brush roller to rotate in reverse, efficiently removing debris from the underside (return side) of the belt.
- Common Features: Scrapers or bristles are pressed tightly against the conveyor belt's working surface at a set angle and pressure, directing the removed material into a collection hopper.
Liquid Jet Flushing (Kinetic Energy-Driven)
- Core Mechanism: Utilizes the kinetic energy generated by the belt's movement to drive a hose-type peristaltic structure, pumping flushing liquid (such as water) into an energy-storing jet device.
- Working Process: The flushing liquid is sprayed onto the conveyor belt's working surface with a certain impact force, achieving a scouring cleaning effect.
- Advantages: Requires no external power source, offers high kinetic energy utilization, and allows for flexible installation.
Self-Cleaning Specialty Conveyor Belts (Integrated Automatic Washing)
- Innovative Design: Integrates adjustable cleaning mechanisms directly onto the conveyor belt body, including brushes, scrapers, and water spray covers.
- Self-Maintenance Function: Through electric or mechanical adjustment, the cleaning mechanism moves under the water spray cover, where a water flow automatically cleans the scraper or brush. This prevents dirt buildup from affecting subsequent cleaning performance.
