Abstract

The invention relates to a float-type sludge scraping and suction system and a sludge scraping and suction operation method. The system is composed of a secondary sedimentation pond body, a float boat bridge crane and a sludge suction and scraping device. The secondary sedimentation pond body is used for separating sediment sludge in a pond, and for removing pond bottom sludge. The float boat bridge crane drives the sludge suction and scraping device to perform reciprocation movements in the secondary sedimentation pond. The suction and scraping device sucks and scraps sediment sludge at the bottom of the secondary sedimentation pond. The overall body of the secondary sedimentation pond is a rectangular box body. Reflux canals are arranged on the two sides of the secondary sedimentation pond body, and are arranged along the two sides of the secondary sedimentation pond body. The reflux canals recovers the sediment sludge at the bottom of the secondary sedimentation pond, and discharges the sludge out of the secondary sedimentation pond. The system provided by the invention has the advantages of scientific design, simple structure, easy operation, small volume, smooth continuous travelling, low noise, convenient maintenance, low maintenance cost, automatic travelling correction, simple structure, reasonably layout, low investment, fast effect, low operation cost, convenient management, and wide application range. With the system, no additional antifreeze or heat preservation facility is needed in winters. The system and the method can be widely applied in sedimentation ponds.

Description

technical field [0001] The invention relates to a secondary sedimentation tank cleaning device, in particular to a floating mud scraping and suction system and an operation method for scraping and sucking mud. Background technique [0002] At present, in the secondary sedimentation tank, the mud scraper at the lower part of the mud scraper is used to scrape the sludge at the bottom of the sedimentation tank to the sludge collection tank in the center of the tank body, and the sludge is discharged out of the tank through the sludge discharge pipeline with a pump or by self-pressure. The mud scraper is easy to cause rail gnawing and derailment, and the mud scraper at the bottom of the mud scraper is easy to scratch the bottom of the pool. Its structure is complicated, the maintenance cost is high, the maintenance is cumbersome, it needs to be shut down for maintenance, and it needs to increase antifreeze and heat preservation in winter. Contents of the invention [0003] Th...
