Application scenarios：
The center-driven thickener is mainly used for thickening settled sludge in thickening tanks of small and medium diameters in urban wastewater treatment plants or industrial wastewater treatment projects. This equipment adopts a gravity thickening method to reduce sludge volume, thereby reducing the processing load of sludge dewatering and improving dewatering efficiency. It serves as a pre-treatment step for sludge dewatering operations.
Structure&Principle：
The equipment adopts a center driven, suspended structure. Wastewater flows in through the inlet pipe under the working bridge, diffuses through the draft tube, and spreads evenly toward the periphery of the tank. The drive unit rotates the central vertical shaft, which in turn drives the scraper arms and thickening grid bars to rotate. Through collisions with the grid bars, the sludge particles accelerate their combination and settlement, thereby improving the sludge settling effect. The separated supernatant liquid overflows through the triangular outlet weir plate into the outlet trough for discharge.
Main Features：
1. The working bridge adopts a full bridge structure, and its material can be carbon steel, stainless steel, or concrete.
2. The drive unit uses a vertical three stage cycloidal pinwheel reducer or a combination of a helical gear reducer and a worm gear reducer to ensure output torque and rotational speed.
3. The thickening grid bars are arranged at equal intervals on the scraper arms to enhance the thickening effect.
4. The lower end of the vertical shaft of the sludge scraper is equipped with an underwater bearing and a scraper to prevent deflection of the vertical shaft during rotation and compaction of sludge in the sludge collection tank.
5. Dual mechanical and electrical overload protection is provided for safe and reliable operation.
6. The equipment is easy to operate and can be directly controlled locally or remotely.
