A high-efficiency skimming and mud scraping device

Abstract

The invention relates to the field of sewage treatment devices, in particular to improvement of a slag separating and sludge scraping machine, and provides an efficient slag separating and sludge scraping device which is ingenious in structure, good in stability, high in reliability and not easily and falsely triggered and has good structure strength in the sludge scraping and slag separating process. The device is arranged in a sedimentation tank and comprises a first belt wheel, a second belt wheel, a third belt wheel, a fourth belt wheel, a conveying belt, a plurality of scrapers and a plurality of connecting components, the first belt wheel and the second belt wheel are arranged at two ends of the position below the liquid level in the sedimentation tank, the third belt wheel and the fourth belt wheel are arranged at two ends of the upper position of the bottom surface of the sedimentation tank, the conveying belt is circularly and sequentially wound on the first belt wheel, the second belt wheel, the third belt wheel and the fourth belt wheel, and a plurality of antiskid projections are arranged on the surfaces of the first belt wheel, the second belt wheel, the third belt wheel and the fourth belt wheel. The device has the advantages that the device has good structure strength in the sludge scraping and slag separating process, and the stirring degree of tank water can begreatly reduced.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to the improvement of a skimming mud scraper. Background technique [0002] Sewage treatment sedimentation tanks usually settle sludge at the bottom of the tank during work, and accumulate foam and foam on the water surface in the tank. In this regard, the applicant applied for a Chinese invention patent named "A Skimmer Scraper" with the application number "201210065220.3" on March 13, 2012, and proposed a The scraper can be turned over automatically, so as to avoid the technical solution of stirring the liquid in the pool. [0003] However, after actual use, the applicant found that this case still has the following defects due to its complicated mechanism: 1. Since the case requires high precision for each part, it is very easy to get stuck between the parts As a result, the scraper cannot be turned over or reset, and has a high probability of false triggering; 2. In t...

[0003] However, after actual use, the applicant found that this case still has the following defects due to its complicated mechanism: 1. Since the case requires high precision for each part, it is very easy to get stuck between the parts As a result, the scraper cannot be turned over or reset, and has a high probability of false triggering; 2. In this case, the connection reliability between the "scraper" and the "running belt" is poor, so it is under force. Finally, especially when scraping out the bottom mud, it is very easy to cause problems such as failure of mud scraping due to accidental overturning; 3. In this case, after the scraper is overturned, it will still maintain a certain angle with the running belt, so that it will still be relatively large. Agitation of pool water
