Radial-flow secondary sedimentation tank peripheral driving mud sucker and scraper mud-suction mechanism

Abstract

The invention relates to a radial-flow secondary sedimentation tank peripheral driving mud sucker and scraper mud-suction mechanism. The mud-suction mechanism comprises several mud suction pipes, mud covers, mud suction ports, mud suction nozzles and mud stirring discs. The several mud suction pipes are respectively and vertically arranged inside a mud sucker and scraper. The mud covers are respectively arranged on the corresponding mud suction pipes. The lower end of each mud suction pipe is respectively connected to the corresponding mud suction nozzle. Two sides of the lower end of each mud suction pipe are respectively provided with a pair of mud stirring discs. The lower surface of each mud stirring disc is provided with three symmetrically-arranged mud stirring paddles. The cross section of each stirring paddle is shaped as a trapezoid. The internal terminal angle A of the mud stirring paddle is 88 degrees. The radial-flow secondary sedimentation tank peripheral driving mud sucker and scraper mud-suction mechanism has a simple structure. By the mechanism, mud discharge efficiency is raised, and running resistance is reduced.

Description

technical field [0001] The invention relates to a radial flow type secondary settling tank peripheral drive scraper suction machine, in particular to a radial flow type secondary settling tank peripheral drive scraper suction mud suction mechanism. Background technique [0002] When scraping and sucking large-scale iron and steel plate sludge, it often happens that the scraper and suction machine travels too fast, which will affect the normal sedimentation of sludge. The walking machine is overloaded, the mud scraping resistance is large, the power consumption is large, the operating cost is high, and even the motor may burn out, which is prone to accidents. Contents of the invention [0003] In order to solve the above problems, the present invention provides a mud suction mechanism of a radial flow type secondary settling tank peripheral transmission scraper and suction dredger with simple structure, improved mud discharge efficiency and reduced running resistance.

Problems solved by technology

[0002] When scraping and sucking large-scale iron and steel plate sludge, it often happens that the scraper and suction machine travels too fast, which will affect the normal sedimentation of sludge. No movement, no mud suction, overload operation of the walking machine, large mud scraping resistance, high power consumption, high operating cost, and even burnout of the motor, which is prone to accidents
