The working principle of a peripheral drive scraper involves the following steps:
Rotation: The peripheral driving sludge thickener, usually a motor or a gear-driven system, rotates the scraper arms or blades at a slow and steady speed. The rotation is supported by wheels or rails that are positioned along the perimeter of the tank.
sludge thickener: As the sludge thickener arms move along the tank floor, the blades or teeth attached to them scrape the settled sludge or solids towards the sludge hopper. The scraper blades can be designed in various configurations to suit different sedimentation tank geometries and sludge characteristics.
Collection: The scraped sludge is accumulated in the sludge hopper or collection trough located at one end of the tank. The sludge hopper is typically equipped with a sludge pump or a gravity discharge system to remove the collected sludge from the tank.
Return: After the sludge is collected, the scraper arms return to their initial position to repeat the scraping process. This continuous operation ensures efficient removal of settled solids from the tank bottom.
Efficient Sludge Removal: The rotating motion of the scraper arms ensures thorough and systematic removal of settled solids from the tank floor. This helps to prevent sludge build-up, maintain sedimentation efficiency, and improve the overall performance of the clarifier or sedimentation process.
Versatility: Peripheral drive scrapers can be adapted to different tank sizes and configurations. The design can be customized to suit specific tank geometries and sludge characteristics, allowing for efficient operation in various wastewater treatment applications.
Simple Maintenance: The peripheral drive mechanism is typically located outside the tank, making it easily accessible for maintenance and repair. Depending on the design, the scraper blades or arms can be quickly replaced or adjusted, minimizing downtime and ensuring smooth operation.
Energy Efficiency: Peripheral drive scrapers generally consume less energy compared to other sludge removal methods, such as suction or suction-lift scrapers. The slow and steady rotation of the scraper arms requires lower power input, resulting in reduced operating costs.
