Riverway culvert sludge collector and jet flow assemblies

Abstract

The invention provides a riverway culvert sludge collector. The riverway culvert sludge collector comprises a jet pipe for circulating a high-pressure medium, a negative pressure pipe with a hollow inner cavity, a suction pipe with an inlet and an outlet, and a plurality of jet flow assemblies for jetting the high-pressure medium; the outlet of the suction pipe is in communication with and in buttjoint with an inner cavity of a negative pressure pipe, and each jet flow assembly is at least partially located in the inner cavity of the negative pressure pipe so that the inner cavity of the negative pressure pipe can be in a negative pressure state by jetting the high-pressure medium; and meanwhile, the jet flow assemblies are arranged around the outlet of the suction pipe, and the angle ofthe jet flow assemblies relative to the axis of the outlet is adjustable, so that the jet flow assemblies close to or away from each other. The sludge collector has a good sludge suction function, canprevent blockage, can greatly improve the sludge suction efficiency and is longer in service life compared with a common sludge collector.

Description

technical field [0001] The invention relates to a river channel sludge treatment device, and specifically designs a river channel culvert sludge collector. Background technique [0002] With the intensification of urbanization, the space of many urban rivers has been continuously occupied and squeezed, and some rivers have been transformed into hidden meanings. When the naturally flowing river is transformed into a hidden culvert, the river itself has only the functions of flood discharge, drainage, water storage, landscape, and humanities, and the above-ground buildings often secretly discharge sewage into the hidden culvert. Due to the long-term dark and confined space, it is very easy to produce anaerobic odor, so it is easy to deposit silt, and the river channel becomes a "dead river". Therefore, the dredging and maintenance of hidden culverts is the most important thing in the regulation of hidden culverts. However, the treatment of river culvert sludge has always bee...

AI Technical Summary

Problems solved by technology

However, the treatment of river culvert sludge has always been a difficult problem. First, the existing sludge collectors are generally used for river silt cleaning, but less for river culverts; secondly, the current sludge collectors are not efficient enough High, the desilting effect is poor; thirdly, because there are large objects such as bottles hidden in the river sludge, it is very easy to cause blockage to the sludge collector, resulting in equipment failure or failure damage
