Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment equipment, in particular to a traveling type sludge scraping and suction machine. Background Art

[0002] The sedimentation tank used for sewage treatment will accumulate a large amount of sludge at the bottom of the tank after flocculation, sedimentation, aerobic and anaerobic treatment processes during the sewage treatment process. If it is not treated in time, it will affect the sewage treatment effect. The traveling sludge scraper and suction machine has a good sludge removal effect and is widely used in the field of sedimentation tank sludge cleaning technology.

[0003] When in use, the mobile sludge scraper and suction machine will move on the edges of both sides of the upper end of the horizontal flow sedimentation tank, and the multiple sludge suction pipes arranged in a linear array on it will suck away the sludge at the bottom of the tank, and the scraper at the bottom can also scrape away the sludge at the bottom of the tank. However, due to the long-term sedimentation, the sludge suction pipe is prone to blockage, which affects the effect of sludge suction; at the same time, due to the limited area of ​​sludge suction by a single sludge suction pipe, the multiple sludge suction pipes arranged in a linear array are relatively ineffective in sucking sludge from the bottom of the tank. For this reason, we propose a mobile sludge scraper and suction machine. Utility Model Content

[0023] Working principle: First, connect the electric push rod 3 on the connecting plate 2 to the external power supply, the telescopic shaft of the electric push rod 3 will move downward, thereby driving the rectangular plate 15 to move downward, the rectangular plate 15 will drive the two connecting rods 12 to rotate downward on the movable frame 1, and the two connecting rods 12 will drive the L-shaped scraper 7, the fixed plate 8, the multiple mud suction pipes 9 and the multiple V-shaped scrapers 11 to move downward together until the bottom ends of the L-shaped scraper 7 and the multiple V-shaped scrapers 11 are in contact with the bottom of the pool.
