Abstract

The invention discloses a reverse-flow sedimentation tank inclined pipe flushing system, which comprises a sedimentation tank body. The sedimentation tank body is internally and sequentially providedwith a mud sinking area, an inclined pipe sedimentation area and a water collecting area from bottom to top, wherein the mud sinking area, the inclined pipe sedimentation area and the water collectingarea communicate; a flushing device is arranged in the water collecting area and comprises a supporting frame with the length being the same as the width of the sedimentation tank body; a cleaning main pipe is arranged on the lower part of the supporting frame; a plurality of sets of inverted U-shaped flushing pipes are arranged on the cleaning main pipe; small submersible pumps are arranged at one ends of the U-shaped flushing pipes, manual ball valves are arranged in the middle sections of the U-shaped flushing pipes, and the other ends of the U-shaped flushing pipes communicate with the cleaning main pipe; cleaning branch pipes are arranged on the two sides of the cleaning main pipe; the lower ends of the cleaning branch pipes are provided with low-pressure cleaning spray heads; the supporting frame is provided with a moving mechanism for moving the flushing device front and back; and a mud discharge pipeline is arranged at the bottom of the mud sinking area, and one end of the muddischarge pipeline extends out of the sedimentation tank body to be provided with a mud discharge pump. The efficiency of flushing collected mud in an inclined pipe is greatly improved, flushing is convenient, and labor and material resources are saved.

Description

technical field [0001] The invention relates to the technical field of domestic and industrial water supply and sewage treatment, in particular to an inclined pipe flushing system of a reverse flow sedimentation tank. Background technique [0002] A sedimentation tank is a structure that uses sedimentation to remove suspended solids in water. Sedimentation tanks are widely used in wastewater treatment. [0003] Inclined tube sedimentation tank refers to a sedimentation tank with inclined tubes in the sedimentation area. The inclined tube sedimentation tank is divided into three different separation methods: reverse (different) flow, cocurrent flow and side flow according to their mutual movement directions. Between every two parallel sloping plates (or in parallel pipes) is equivalent to a very shallow sedimentation tank. The advantages of the inclined tube sedimentation tank are: ①Using the principle of laminar flow, the processing capacity of the sedimentation tank is i...
