Walking type sludge suction device for wastewater treatment

Abstract

The invention provides a walking type sludge suction device for wastewater treatment and belongs to the technical field of sewage treatment. A plurality of sludge suction branch pipes are arranged atthe bottom in a tank body; the lower part of each sludge suction branch pipe is communicated with a plurality of sludge suction openings; the upper part of each sludge suction branch pipe is connectedwith an inlet of a sludge suction pump through a pipeline; an outlet of the sludge suction pump is connected with sludge suction general pipes; each sludge suction general pipe is communicated with asludge discharging pipe; an outlet end of the sludge discharging pipe is located at the outer part of the tank body; the sludge suction pump is fixed on a pump supporting platform; the pump supporting platform is fixed on a transverse pipeline bracket; the sludge suction branch pipes are erected on the transverse pipeline bracket. According to the walking type sludge suction device, a walking type sludge suction vehicle is adopted and is operated under water, so that the walking type sludge suction device can reach any part of a tank bottom and can walk and suck sludge at the same time; the problem of cleaning the sludge at the tank bottom can be completely solved and the complete sludge discharging effect is realized, so that the practicability is stronger.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a walking mud suction device for waste water treatment. Background technique [0002] Regulating ponds, advection grit chambers, advection sedimentation tanks, and emergency ponds in sewage treatment plants; advection grit chambers in waterworks often accumulate a layer of sludge at the bottom of the ponds. Though be provided with mud discharge system, for the larger pool of pond body 18 areas, because the mud discharge pipe is too long, often there is mud discharge difficulty, the phenomenon that mud discharge is not exhausted. Especially for large-scale municipal sewage plants, the general peripheral transmission scraper and suction machine cannot effectively scrape the sludge at the bottom of the pool, and there are dead spots for sludge discharge. Moreover, the investment and operating costs of the transmission sludge scraper are high, which needs to be improved urge...

AI Technical Summary

Problems solved by technology

Although there is a mud discharge system, for a pool with a large area of ​​the pool body 18, due to the long mud discharge pipe, it is often difficult to discharge mud and the phenomenon of endless mud discharge

Especially for large-scale municipal sewage plants, the use of general peripheral transmission sludge scrapers cannot effectively scrape the sludge at the bottom of the pool, and there are dead spots for sludge discharge, and the investment and operating costs of transmission sludge scrapers are high, which needs to be improved urgently
