Suspended central drive thickener is mainly used in urban sewage treatment plants or industrial wastewater treatment projects in medium and small diameter thickening tanks to thicken sedimented sludge. This equipment adopts the method of gravity concentration to reduce the volume of sludge and reduce the The processing load of sludge dewatering can improve the dewatering effect as a pretreatment of sludge dewatering operation.
The equipment adopts a chain plate rotary type, and the water-passing grid surface is composed of fixed grid bars. When the sewage flows through, the debris larger than the grid gap is intercepted, and the rake teeth of the rake tooth plate go deep into the gap of the grid bars. When the driving device drives the traction When the chain rotates, the rake teeth bring the debris trapped on the grid surface to the slag outlet from bottom to top, the debris falls off by gravity, and falls into the conveyor or garbage trolley from the discharge port, and then is transported out or for further processing.
