1、 Purpose:
The ZXG suspended center drive scraper is suitable for small and medium-sized radial flow sedimentation tanks with central inlet, peripheral outlet, and central discharge. It is mainly used for sedimentation tank discharge in urban sewage treatment plants or industrial wastewater treatment projects.
2、 Structure and working principle
The equipment adopts a central transmission system. Sewage flows into the water pipe from under the working bridge, and after diffusion through the guide tube, it flows out uniformly in a radial manner to the surroundings. The suspended sludge settles at the bottom of the tank after sedimentation. The driving device drives the central vertical shaft to rotate, and drives the scraper arm and scraper to rotate. The scraper collects the sludge and is sucked into the sludge collection tank by the suction pipe relying on the static water pressure in the tank, and then discharged into the central sludge tank through the central discharge pipe. The floating slag on the water surface is introduced into the slag discharge hopper through the rotating skimming device and discharged outside the tank, while the supernatant overflows into the discharge tank through the triangular outlet weir and is discharged.
