A sludge cleaning device and cleaning method based on river ecosystem

Abstract

The invention discloses a sludge cleaning device and cleaning method based on river ecosystems. The sludge cleaning device comprises a supporting frame, a treatment box and a desilting tank, wherein the treatment box is arranged on one side of the supporting frame and arranged above the desilting tank; a fixed shell is fixedly installed at the top of the supporting frame; a water inlet pipe is installed on one side of the top of the fixed shell, and the water inlet pipe penetrates through the top of the fixed shell; a first connecting shaft and a second connecting shaft are arranged in an inner cavity of the water inlet pipe; and the first connecting shaft and the second connecting shaft are arranged on a same horizontal plane and sleeved with crushing sleeves. Through the design of a water conveying auger and a cutting blade, existing silt is effectively beaten while river water is conveyed, and sludge and other solid impurities existing in the river water are effectively removed in cooperation with crushing of a crushing sheet and a fixing sheet; and the technical problem that the sludge and other solid impurities in the river water are difficult to clean in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of water treatment of river ecosystems, in particular to a device for cleaning sludge based on river ecosystems and a cleaning method thereof. Background technique [0002] The river ecosystem refers to the ecosystem of the river water body, which is a kind of flowing water ecosystem. It is the link between the land and the sea, and plays a major role in the material cycle of the biosphere. River ecosystems include a series of subsystems including terrestrial riparian ecosystems, water ecosystems, related wetlands and swamp ecosystems. function and many other functions. The continuous flow of water in the river ecosystem makes the dissolved oxygen relatively sufficient, and the stratification is not obvious. [0003] The patent document (201710591836.7) discloses a river sewage sludge filtration device and a river sewage sludge treatment system. By stacking three-stage filter screens in the drum, the filte...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of sludge cleaning device and cleaning method based on the river ecosystem, solve the following technical problems: (1) drive the second connecting shaft to rotate through the first motor output shaft, and the second connecting shaft is driven by the gear The first connecting shaft rotates, and the first connecting shaft and the second connecting shaft drive the broken piece to rotate through the crushing sleeve. The broken piece cooperates with the fixed piece to crush the large-grained sediment in the river water, and the large-grained sediment flows to the conveying cylinder with the river water Inside, through the design of the upper semi-arc opening of the crushing piece and the fixing piece, the large-grained sediment in the river water is effectively crushed when the river water is transported, the output shaft of the second motor drives the second sprocket to rotate, and the second chain The wheel drives the first sprocket to rotate through the chain, the first sprocket drives the conveying shaft to rotate, the conveying shaft drives the water delivery dragon to rotate, the water delivery dragon conveys the river water to flow out from the water outlet, and the conveying shaft drives the cutting piece to rotate through the knife sleeve, cutting The sheet crushes the sediment in the river water, and the river water is transported to the filter belt in the treatment box through the conveying pipe. Through the design of the water delivery dragon and the cutting sheet, the river water is transported while the existing sediment is crushed. Effective beating, combined with the crushing of broken pieces and fixed pieces, effectively cleans the sludge and other solid impurities in the river water, and solves the technical problem that the sludge and other solid impurities in the river water are difficult to clean in the prior art; (2) The third motor drives the filter belt to rotate through the first drive shaft and the second drive shaft, and the telescopic cylinder pushes the lifting plate downward through the thrust seat, and then drives the connecting plate to descend, and the rod sleeve on the lifting plate goes down along the fixed rod When moving, the pressing plate at the bottom of the spring rod first contacts and presses the filter belt, and then the spring rod contracts, and the sand scraping plate touches the top of the filter belt, and the sand scraping plate scrapes off the sludge on the filter belt. Through the design of the pressing plate, Press the filter belt before scraping the sand with the sand scraper to effectively prevent the filter belt from loosening after long-term use and affect the mud scraping effect of the sand scraper, improve the mud scraping effect of the sand scraper, and solve the problem In the technology, the filter belt may loosen after being used for a long time, and there is a gap between the filter belt and the filter belt when the mud is scraped by the sand scraping board, which affects the technical problem of sludge scraping; (3) by opening the sand sinking pipe When the valve is opened and closed, the sludge enters the sedimentation tank and is guided to the mud delivery dragon through the guide plate. The fourth motor drives the mud delivery dragon to rotate, and the mud delivery dragon discharges the sludge from the mud outlet. Through the above structure, the The sludge in the river water is effectively separated and collected. Through the setting of the guide plate and the mud transport dragon, the sludge is conveniently transported and collected, and the technical problem that the sludge in the river water is not easy to separate and difficult to transport after separation in the prior art is solved.
