1. Working principle 
    This machine is suitable for mechanical sludge discharge of radial flow or vertical flow sedimentation tanks without central piers. The machine is provided with a fixed platform across the pool, and the whole machine load acts on the center of the working bridge when working. The sewage flows evenly around the pool through the center diversion tube of the pool. With the decrease of the flow rate, the suspended matter in the sewage settles at the bottom of the pool. discharged from the sludge pipe.
