Compared with the prior art, the beneficial effects of the utility model are that:
1. automatic backwash swash plate mud scraper under do not shut down work, do not disturb sedimentation tank bottom sludge deposit's prerequisite, set for the backwash cycle according to the mud gathering state and carry out automatic backwash of not stopping water, effectively get rid of sedimentary mud on the swash plate.
2. Fixed air supply pipeline and rotatory air supply pipeline adopt rotary joint to be connected, be with gaseous from fixed air supply pipeline input to rotatory air supply pipeline, from the sealing device that wherein exhaust connection used again, not only nimble convenience but also effectively guarantee the leakproofness of two air supply pipelines to it is better to guarantee the cleaning performance.
3. Cloth trachea be located scrape mud arm upper end and close on the honeycomb swash plate, avoid cloth trachea position to cross lowly and disturb the mud layer, be favorable to sludge settling, improved the work efficiency of mud scraper, reduced the atmospheric pressure and the energy consumption of fan simultaneously, the cost is reduced.
4. The gas distribution hole is arranged below the gas distribution pipe, gas is distributed more evenly before going down and then going up, and the gas hole can not be blocked. The gas distribution hole trompil interval reduces to the gas distribution pipe end along rotatory air supply pipeline gradually, and the diameter size of gas distribution hole is crescent to the gas distribution pipe end along rotatory air supply pipeline, and the gas distribution is reasonable, and the gas distribution pipe is rotatory along scraping the mud arm, carries out scanning formula backwash to the swash plate, effectively improves gas washing frequency and intensity.
5. High pressure nozzle be rotation type high pressure nozzle, a plurality of high pressure nozzle carries out the rotation type according to honeycomb swash plate incline direction and washes, the two-way washing that high pressure water cleaning and gas washing combine has further reduced and has washd the dead angle, has guaranteed the cleaning performance, has improved the cleaning efficiency.
