A device for skimming and scraping mud

Abstract

The invention discloses a skimming and mud scraping device, relates to the field of sewage treatment equipment, and particularly relates to improvement on skimming and mud scraping machines. The skimming and mud scraping device is exquisite in structure, good in stability and high in reliability and is good in structural strength during mud scraping and skimming, and false triggering can be prevented. The skimming and mud scraping device is arranged in a settling pond and comprises a first belt pulley, a second belt pulley, a third belt pulley, a fourth belt pulley, a conveyor belt, a plurality of scraping plates and a plurality of connecting assemblies. The first belt pulley and the second belt pulley are arranged at two ends of a location which is positioned below the internal liquid level of the settling pond, the third belt pulley and the fourth belt pulley are arranged at two ends of the upper portion of the bottom surface of the settling pond, and the conveyor belt is annularly sequentially wound on the first belt pulley, the second belt pulley, the third belt pulley and the fourth belt pulley. The skimming and mud scraping device integrally has the advantages that the skimming and mud scraping device is exquisite in structure, good in stability and high in reliability and is good in structural strength during mud scraping and skimming, the false triggering can be prevented, and the stirring degree of pond water can be lowered to a great extent.

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
