Flow guide desilting equipment

Abstract

The invention discloses flow guide desilting equipment. The flow guide desilting equipment comprises a flow guide assembly, a power conversion assembly and a spiral flow generation assembly. According to the invention, the flow guide assembly controls silt-containing water flow introduced into a flow guide groove, the impact of the water flow on the power conversion assembly is utilized to drive the spiral flow generation assembly to work, the spiral flow generating assembly triggers surrounding water flow to generate spiral flows in different forms through rotation of a spiral flow driving wheel and reciprocating lifting motion on a lead screw, and therefore sludge sand deposited in the desilting process can be effectively removed. The spiral flow generation assembly works to drive an aeration assembly to aerate an MBR biological membrane plate, so that pollutants are degraded by strains on the MBR biological membrane plate when the water flow passes through the MBR biological membrane plate, a membrane contact oxidation treatment process and bacterium killing are realized, so that the biological viscosity of the sludge sand is effectively reduced, the sludge sand is prevented from adhering to the flow guide groove, and the flow guide desilting effect is improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic construction equipment, in particular to diversion and sand removal equipment. Background technique [0002] During the construction of hydraulic structures, a large amount of silt and sand will adhere to the surface of hydraulic structures. Since the silt contains a large number of bacteria and has a certain degree of adhesion, it will affect the construction if it adheres to the surface of the hydraulic structure. Therefore, it is necessary to discharge the silt. At present, the industry generally uses the flow of water. The method is to carry the silt and sand deposited on the hydraulic structures, but this method is not suitable for the dry season, and it is difficult to effectively remove the sediment silt and sand, which will cause the silt and sand to accumulate during the sand discharge process, which seriously affects the construction work. conduct. [0003] The Chinese patent applica...

AI Technical Summary

Problems solved by technology

Although the scheme of this application can discharge the silt and sand, the helical flow form it produces is relatively simple, and the effect of sand discharge on the silt and sand is relatively poor.
