Mud discharging system for sedimentation tank

Abstract

The invention discloses a mud discharging system for a sedimentation tank, wherein the mud discharging system includes a mud discharging main pipe and a plurality of mud discharging branched pipes connected with the mud discharging main pipe; the mud discharging system is characterized in that at least one inserting port is arranged at each mud discharging branched pipe and is used for connectinga group of rotary mud discharging device; each rotary mud discharging device includes a first perforated mud discharging pipe and a second perforated mud discharging pipe which are arranged at two sides of the inserting ports respectively; opening holes of each first perforated mud discharging pipe and each second perforated mud discharging pipe face to two sides respectively; a suction force generated by the rotary mud discharging devices during mud discharging pushes the perforated mud discharging pipes to form automatic rotation. The system is mainly applied in a water treatment sedimentation tank; through arrangement of the rotary mud discharging pipes at the bottom of the tank, the suction force generated during single-side mud discharging is used for driving the mud discharging pipesto rotate, the mud discharging area is enlarged, the mud discharging effect of the sedimentation tank is improved, and the water quality of effluent is avoided from being affected by mud deposits atthe bottom of the sedimentation tank.

Description

technical field [0001] The invention relates to a mud discharge system for a sedimentation tank. This system is mainly used in the water treatment sedimentation process. By arranging a rotating sludge discharge pipe at the bottom of the tank, the suction force generated by the sludge discharge pump is used to drive the sludge discharge pipe to rotate, which expands the sludge discharge area and avoids the occurrence of sludge at the bottom of the tank. Mud. Background technique [0002] Sedimentation tank is one of the common treatment structures in water plants. Through the joint use of coagulation process, it can strengthen the removal of colloid and other pollutants in water, so it is a widely used treatment structure in water treatment process. At present, the more common sedimentation tanks are advection sedimentation tanks and inclined tube sedimentation tanks. In order to ensure the stability of the operation of the sedimentation tank, the sedimentation tank needs t...

Problems solved by technology

[0004] In addition, the traditional perforated mud discharge pipe has holes on both sides and is fixed on the bottom of the pool. The horizontal thrust generated by one side of the mud suction is offset by the horizontal thrust generated by the other side of the mud suction, which does not work effectively, resulting in energy waste.
