Product Description
XNZS Type Center Drive Sludge Scraper, Thickener
Center drive sludge scrapers and thickeners are widely used in wastewater treatment projects in municipal, petrochemical, papermaking, and steel industries. They are generally suitable for various circular thickening tanks with smaller tank diameters, usually with central inflow, central sludge discharge, and peripheral outflow.
Wastewater enters the tank from the center, sludge settles radially to the periphery, supernatant liquid is collected by the peripheral collecting trough, and the thickener scrapes the settled sludge into the central sludge pit for discharge outside the tank.
Features:
Generally uses a large torque drive device, ensuring stable and reliable transmission;
The scraper angle is adjustable to adapt to different pool slopes, and manual rake lifting is possible;
Functions can be expanded, such as adding a torque control indicator and an automatic rake lifting mechanism;
The sludge scraper uses a rubber composite structure for thorough sludge scraping,
Simple structure, easy to install and use.
Working Principle
Wastewater enters the sedimentation tank through the central calming tube at a certain flow rate. As the flow rate decreases, the inert and active sludge in the wastewater settles to the bottom of the tank. The thickener drive mechanism drives the scraper arm to rotate, and the scraper blades fixed on the scraper arm gradually scrape the settled sludge from the edge of the tank to the central sludge hopper. The thickening bars installed on the scraper arm rotate accordingly, accelerating sludge sedimentation. The sludge is discharged from the tank under its own water pressure (or water pump) and flows into the next process through the effluent weir plate to remove the settled sludge in the wastewater.
