Peripheral transmission aspiration sludge scraper for sewage treatment

Abstract

The invention discloses a peripheral transmission aspiration sludge scraper for sewage treatment. The peripheral transmission aspiration sludge scraper for sewage treatment comprises a vehicle body, the middle of the vehicle body is of an arched structure; the upper end of the arched structure is fixedly connected with a limiting seat; a bearing is fixedly connected to the upper end of the limiting seat in a penetrating manner; the inner ring of the bearing is fixedly connected with a rotating pipe in a sleeving manner; an internal thread is formed in the inner wall of the rotating pipe; a connecting column is in threaded sleeve connection with the interior of the rotating pipe; the lower end of the connecting column penetrates through and extends to the bottom of the vehicle body and is connected with a mud scraping mechanism, a vertically-arranged limiting groove is formed in the side wall of the connecting column, a limiting rod is further fixedly connected to the bottom of the vehicle body, and one end of the limiting rod is inserted into the limiting groove and is in sliding connection with the limiting groove. According to the peripheral transmission aspiration sludge scraper, the mud scraping range of a mud scraper in unit time can be larger, so that the mud scraping efficiency is higher; the sludge scraping depth can be adjusted according to the thickness of deposited sludge; and the scraped sludge can be collected in a centralized manner and quickly cleaned, so that the use is very convenient.

Description

technical field [0001] The invention relates to the technical field of mud scrapers, in particular to a peripheral transmission suction mud scraper for sewage treatment. Background technique [0002] In the industrial sewage treatment system, because the residue in the sewage agglomerates and becomes sludge, a sludge scraper is needed. Peripheral drive mud scraper is a more commonly used sedimentation tank scraper equipment in industrial sewage treatment systems. However, due to the inability of the mud scraper to move in the existing peripheral transmission mud scraper, the mud scraping range per unit time of the mud scraper is small, and the mud scraping efficiency is low; moreover, the existing peripheral transmission suction mud scraper cannot The thickness of the mud adjusts the depth of mud scraping, which is inconvenient to use. [0003] For this reason, we have proposed a kind of peripheral drive suction mud scraper for sewage treatment. Contents of the invention...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing peripheral transmission suction mud scraper in the prior art cannot move the mud scraper, the mud scraping range of the mud scraper per unit time is small, and the mud scraping efficiency is low; and the existing The peripheral transmission suction mud scraper cannot adjust the scraping depth according to the thickness of the deposited sludge, and it is inconvenient to use, so a peripheral transmission suction mud scraper for sewage treatment is proposed
