AI Technical Summary

Technical Problem

In the prior art, the scraper plate can only clean the bottom of the pool, and cannot effectively clean the residue on the pool wall, and the residue can easily cause the suction pipe to be blocked after scraping.

Method used

A double-tube mud suction machine with a slag scraping mechanism is designed, adopting a special structure of a V-shaped plate, so that the residue is squeezed and moved by itself after being scraped. The residue is moved from rectangular frame one to slam frame two through the rotation of the power shaft, and finally transported into the annular channel through the discharge barrel.

Benefits of technology

The problems of suction pipe blockage and pool wall cleaning are effectively solved. Through the rotation of the power shaft, the squeeze pressure of the residue is continuously increased, the risk of blockage is reduced, and the pool wall is comprehensively cleaned.

Abstract

The utility model relates to the field of sewage treatment, in particular to a double-pipe suction dredger with a slag scraping mechanism, which comprises a treatment tank body, a power shaft is mounted in the treatment tank body, a first sludge suction pipe is mounted below the power shaft, and a second sludge suction pipe is mounted on one side, far away from the first sludge suction pipe, of the power shaft. By means of the special structure of the first V-shaped plate, the second V-shaped plate, the third V-shaped plate and the fourth V-shaped plate, residues can be left in gaps of the structure after being scraped, the residues are squeezed along with continuous increase of the residues, the residues in the first rectangular frame move into the second rectangular frame along with continuous rotation of the power shaft, and the residues in the second rectangular frame move into the first rectangular frame. And through the structure, as long as the power shaft rotates, the extrusion pressure of the residues in the first rectangular frame and the second rectangular frame can be continuously increased, so that the risk of blockage is reduced, and the inner wall of the treatment pond body can be cleaned through the second rectangular frame.
