Description

Central transmission mud scraper with flushing inclined pipe

Technical Field

The utility model belongs to the technical field of the environmental protection equipment technique and specifically relates to a central transmission mud scraper of pipe chute is washed in area is related to.

Background

The inclined tube sedimentation tank is a sedimentation tank with inclined tubes arranged in a sedimentation area, a series of shallow sedimentation layers are divided in the sedimentation area of the horizontal flow type or vertical flow type sedimentation tank by utilizing inclined parallel tubes, parallel pipelines, honeycomb fillers and the like, and the settled mud is precipitated in the inclined tube fillers and separated from water.

The suspended matters are more or less adhered to the surface of the inclined tube in the rising process, and sludge lumps can be formed after the suspended matters accumulate for a long time. On one hand, the water passing area is reduced, the water passing hydraulic load is increased, the sludge settling time is shortened, and some suspended matters with small specific gravity can not be completely settled; on the other hand, along with the hydraulic flushing, sludge flocs adhered to the inclined pipe can be flushed and separated, and suspended matters exceed the standard along with the outlet water, so that the inclined pipe needs to be flushed at intervals. However, as the inclined tube filling is generally arranged in the middle of the water tank, the water level of the water tank needs to be emptied to one third, and then the water tank is manually flushed by a high-pressure water gun. The whole cleaning process takes long time, the labor intensity is high, and the cleaning effect is poor.
