A stable skimming and mud scraping device

Abstract

The invention provides a stable type skimming and mud scraping device, relates to the field of sewage treatment equipment and in particular relates to improvement of a skimming and mud scraping machine. The invention provides the stable type skimming and mud scraping device which has an ingenious structure, good stability and high reliability, is not easily triggered by mistake and has relativelygood structure strength in mud scraping and skimming processes. The stable type skimming and mud scraping device is arranged in a sedimentation tank and comprises a belt wheel I, a belt wheel II, a belt wheel III, a belt wheel IV, a conveyor belt, a plurality of scraping plates and a plurality of connecting assemblies, wherein the belt wheel I and the belt wheel II are arranged at two ends of a position below a liquid surface in the sedimentation tank; the belt wheel III and the belt wheel IV are arranged at two ends of a position at the upper part of the bottom surface of the sedimentation tank; the conveyor belt is annular and is arranged around the belt wheel I, the belt wheel II, the belt wheel III and the belt wheel IV in sequence; a plurality of anti-slipping bulges are arranged on the surfaces of the belt wheel I, the belt wheel II, the belt wheel III and the belt wheel IV; the plurality of scraping plates are connected onto the conveyor belt through the connecting assemblies. The stable type skimming and mud scraping device provided by the invention has relatively good structure strength in the mud scraping and skimming processes and can greatly reduce the stirring degree of pond water.

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
