Description

An anti-clogging quick disassembly mud scraper

technical field

The utility model relates to the technical field of mud scrapers, in particular to an anti-clogging quick dismountable mud scraper.

Background technique

Sludge scraper is a large-scale equipment used for sewage treatment. The traditional working method is that the worm gear box drives the main shaft to rotate, and the scraper arm scrapes the sludge to the pool center pit with the rotation of the main shaft. The sludge is automatically discharged out of the pool under hydrostatic pressure. The structure of the scraper is matched with the bottom structure of the sewage treatment tank to scrape the sludge at the bottom of the sewage treatment tank. Under the action of water pressure, the sludge will automatically enter the sludge collection tank at the bottom for discharge.

However, during long-term use, the scraper will rub against the bottom of the treatment tank, resulting in wear of the scraper. The existing scraper is generally welded and fixed on site or connected by bolts, which is very troublesome to disassemble. It is beneficial to the daily maintenance of the mud scraper. In addition, in the actual operation process, when all the sludge is accumulated inside the sludge pit, because the sludge is relatively viscous and under the action of the upper water pressure, it often cannot be discharged smoothly, which will cause the blockage of the sludge discharge outlet. Some mud scrapers are equipped with stirring blades inside the mud pit, but the effect is not obvious, and the sludge discharge efficiency of the mud pit is low.

Further, the scraper is made of rubber sheet.

Further, the outer end of the support bar is provided with a hoisting ring to facilitate its hoisting.

The beneficial effects of the utility model are:

1. The main shaft is located on the outside of the shaft body in the mud collecting pit, and there is a variable-diameter spiral belt. Through the rotation of the variable-diameter spiral belt, the viscous sludge overcomes the effect of water pressure and continues to enter the mud pumping pipe, and then in the screw conveying mechanism. It is discharged under the action, effectively avoiding the occurrence of clogging.

2. When the scraper in the mud scraper assembly is worn out, the compression spring stretches to move the new scraping surface of the scraper to the original scraping surface position. In this way, the utilization rate of the scraper is greatly improved, as long as the scraper is replaced regularly, There is no need to consider the problem of poor mud scraping effect due to wear. The support bar can be hoisted by the lifting ring, which is convenient for daily observation of scraper wear and replacement of scraper.

Of course, any product implementing the present utility model does not necessarily need to achieve all the above-mentioned advantages at the same time.
