The overhead center-drive sludge scraper is suitable for large and medium-sized radial flow sedimentation tanks with central water intake, peripheral effluent, and central mud discharge, mainly used for sludge suction and discharge in the secondary sedimentation tanks of urban wastewater treatment plants.

Usage:

Centrifugal sludge scraper and suction machine with suspended frame is suitable for large and medium-sized radial flow sedimentation tanks with central water intake, peripheral effluent, and central sludge discharge, mainly used for sludge suction and discharge in the secondary sedimentation tanks of urban wastewater treatment plants.

Structure and Working Principle

The equipment features a central drive and vertical frame design. Wastewater enters the guide tube from the inlet column pipe, spreads after flowing into the guide tube, and uniformly radiates outward around the periphery. Suspended sludge settles and accumulates at the bottom of the pool. The driving unit rotates the central vertical frame, which in turn drives the scraper arm and sludge scraper to rotate. The scraper collects the sludge and transfers it to the central sludge tank via the suction pipe, which draws the sludge using the static water pressure within the pool. The sludge is then discharged out of the pool through the central sludge discharge pipe. Floating debris on the water surface is removed by the rotating skimming device and discharged into the waste sludge hopper, while the clarified liquid overflows through the triangular weir plate into the effluent trough.

Key Features of the Type Center Drive Scrubber-Suction Machine with Overhanging Arm

The work adopts a half-bridge design, with the material available in carbon steel or stainless steel structures.

The drive unit combines bevel gear and worm gear reducers to ensure output torque and speed, delivering high transmission efficiency.

The reducer is equipped with an overload torque protection device, ensuring safe and reliable operation; there are two types of slag removal methods: plate-type slag removal and pipe-type slag removal.

Each污泥管 is a standalone unit, with flow regulation possible through the opening of the污泥管 mouth, thereby controlling the污泥回流 ratio.

The equipment is easy to operate, allowing for direct on-site or remote control of its operation.
