Background

The traditional disturbing bed separator (TBS for short) is a disturbing sedimentation type separator which utilizes the turbulent flow effect generated by the rising water flow with a certain pressure at the bottom of the tank body in the tank to separate coarse particle materials (0.15-2 mm).

When the rising water flow is sent to the pressure box at a preset pressure and flow speed, the rising water flow is uniformly dispersed to the bottom of the TBS box body from the pressure box through the turbulence plate, a bed layer composed of suspended particles is formed at the lower part of the interference bed, and the particles in the bed layer are highly enriched to form an autogenous medium. The particles interfere with each other during the descent to form a different density gradient in the suspension to limit the passage of material through the underflow. After entering the TBS, the materials are layered, coarse or heavy materials are concentrated at the bottom of the tank body, fine materials and all light materials are moved towards the upper part, along with the feeding of new materials, the fine and light materials pass through the overflow weir to the overflow water tank, the coarse or heavy materials which are settled to the bottom are discharged through the conical valve, and the conical valve is automatically controlled by the PLC.
