Problems solved by technology

The latter is a rectangular structure. The sediment slides down the wall of the inclined pipe to the sedimentation tank, and is collected by the scraper installed on the endless chain to one end. The efficiency of clear water flowing out of the inclined pipe covered with the water surface is greatly improved, but there are also Some problems, the link of the ring chain is easy to break after wear and tear, and the ring chain is always kept at the bottom of the pool. Due to equipment failure and sudden power failure and other abnormal parki

Example Embodiment

[0025] The present invention can be applied to multiple types of concentrators. In the embodiment, the description of further development in conjunction with the concentrator is as follows:

[0026] In the embodiment, Fig. 1 and Fig. 2 show a thickener mud scraper system, which includes a common thickener pool 2, a collection pit 1 and the mud scraper of the present invention. The mud scraping method described in the present invention is a reciprocating relay method. The mud scraper is a plurality of scrapers 5 equidistantly suspended on a rail car 3, and the scrapers 5 are naturally dragged and dropped to the bottom of the pool at a certain angle, and the rail car 3 is dragged by a traction device to reciprocate along the track 4. When there is a certain thickness of sediment at the bottom of the pool, when the rail car 3 moves back away from the collection pit 1, the scraper 5 is pulled out and dragged back along the mud surface; when moving forward, the scraper 5 goes deep ...

Abstract

The present invention relates to a sewage deposit collecting method and device for a concentrator, especially relates to a to-and-fro relay type mud scraping method and mud scraping machine. Said mud scraping machine includes several scraping plates which are equidistantly hung on a railcar. The scraping plates are towed by the railcar to move to and fro to collect the deposit in a deposit tank from one end to the other end. The maximum travel of the railcar is bigger or equal to the distance between the scraping plates, as a result, consistent collection of all the deposit can be realized. The scraping depth and angle of the mud scraping plate in this invention can be adjusted naturally, leading to a result of high work efficiency and labour saving, further, it is suitable for wide work range and has the advantages of reliable work, low investment and long service life.

Description

Technical field [0001] The invention relates to a method and equipment for collecting sewage sediment from a concentrator, in particular to a reciprocating relay type mud scraping method and a mud scraper. Background technique [0002] At present, there are two types of thickeners used in coal preparation plants and sewage treatment plants at home and abroad: climbing thickeners and inclined tube thickeners. The former is a circular structure, and the aggregate crawls around the center and the sediment is collected to the center. Sewage is fed in from the center, and the overflow efficiency of clean water is low. The latter is a rectangular structure. The sediment slides down the wall of the inclined pipe to the sedimentation tank, and is collected by the scraper installed on the endless chain to one end. The efficiency of clear water flowing out of the inclined pipe covered with the water surface is greatly improved, but there are also Some problems, the link of the ring c...
