Novel peripheral driving mud scraper

Abstract

A new peripheral transmission mud scraper. The utility model provides a novel peripheral transmission mud scraper which is simple in structure, convenient for scraping mud, and improves work efficiency. The mud scraper includes a drive device, a working bridge, a central support, a steady flow cylinder, a scraper, a mud scraper and a water outlet weir arranged around the periphery. The working bridge is driven to rotate around the central support by the drive device. The mud scraper is arranged at the bottom of the sedimentation tank and connected to the working bridge through a truss, and the scraper is arranged at the lower part of the working bridge and above the mud scraper; the mud scraper includes a flat plate and A pair of side plates, the pair of side plates are arranged on both sides of the flat plate and are respectively inclined towards the outside, the bottom surface of the flat plate is provided with two rows of parallel and staggered plate body one and plate body two, the Roller 1 and Roller 2 are evenly distributed on the bottom surface of a pair of side plates respectively; a stirrer is arranged at the center of the bottom of the sedimentation tank. The invention runs smoothly and has good effect of scraping and collecting sludge.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a peripheral transmission mud scraper. Background technique [0002] Peripheral transmission sludge scraper is suitable for radial flow primary or secondary sedimentation tanks in sewage treatment plants. Its main function is to scrape the sludge settled at the bottom of the tank to the central sludge pit, and then discharge it through the sludge discharge pipe so that the sludge can return or Concentration and dehydration, the mud scraper installed under the working bridge is driven by the drive mechanism installed on the periphery, and rotates around the center support installed on the central pier of the pool. The sludge settled at the bottom of the pool is collected by the mud scraper to the central mud pit. Then it is discharged out of the pool by the mud discharge pipe. [0003] In the prior art, there are low reliability of the mud scraping movement of the mud scraper and ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, there are low reliability of the mud scraping movement of the mud scraper and poor mud scraping; at the same time, when the sludge is concentrated to the bottom of the pool, it is prone to blockage, high resistance, and easy to cause damage
