Description

Novel sludge suction dredger

Technical Field

Background

The existing radial flow primary or secondary sedimentation tank of a sewage treatment plant mostly uses a peripheral transmission mud scraper, and the main function of the mud scraper is to scrape and collect the mud settled at the bottom of the tank into a mud collection pit and then discharge the mud through a mud discharge pipe so as to facilitate the backflow or concentration and dehydration of the mud. The peripheral transmission mud scraper can be divided into a full bridge type and a half bridge type by the difference of a working bridge and a mud scraper. The working bridge is driven by a driving mechanism arranged at the periphery, a scraping arm which is hung under the working bridge in a rotating way around a central branch pipe arranged on a buttress at the center of the tank drags a logarithmic spiral scraper to rotate, sludge precipitated at the bottom of the tank is collected to a central mud pit by the scraper, and then is discharged out of the tank by a sludge discharge pipe, scum on the liquid level is concentrated in a reduction area formed by a scum scraper and peripheral slag baffles, and the scum scraper scrapes the scum to a scum collecting hopper and discharges out of the tank.

The problems that exist in the prior multipurpose mud scraper are as follows:

1. the conventional mud scraper with peripheral transmission has the disadvantages of high civil engineering cost and complex process because the bottom of a sedimentation sludge tank required by the conventional mud scraper in large-scale sewage treatment is conical.
