Impeller-less powerful sludge pump

Abstract

An impeller-less powerful sludge pump, comprising a pump body, an air distribution pack, air inlet / outlet flanges, upper and lower fixing boards, and a plurality of tapered air pipes between the upper and lower fixing boards; wherein, the upper and lower fixing boards are in circular shape, a plurality of tapered air pipes are arranged between a plurality of through holes near the outer circumference of the fixing board, and a plurality of cylindrical powerful pressurization rings separated into heterotypic air ducts by a plurality of inclined plates on the inner circumference of the upper and lower circular fixing boards; the air inlets of the powerful pressurization rings and air pipes communicate with the sealed air distribution pack on the pump wall; since the air pipes on the bottom of the sludge pump are in tapered structure, a plurality of heterotypic air ducts are arranged in the powerful pressurization rings, and no impeller is employed in the pump body, the air blasted by anexternal blast fan can form strong swirling eddy similar to cyclone in the sludge pump, and the airflow also has powerful suction force; therefore, slurry obstruction substances can be sucked into the sludge pump and blasted out with the swirling eddy. The pump is suitable for dredging underground sewage pipelines, river courses, and trenches, etc.

Description

【Technical field】 [0001] The invention relates to equipment for dredging and discharging sewage of urban underground sewage pipes and river beds, in particular to a powerful sewage suction pump without impellers. 【Background technique】 [0002] Irrigation channels around cities and towns and underground sewage pipes in cities and towns are often blocked due to the deposition of sediment and insoluble substances, causing river beds to rise and sewage to overflow, causing many troubles to urban sanitation departments in various places. In order to overcome the original and backward status of the existing sewage equipment, and some anti-blocking wind-powered sewage equipment have low sewage suction and poor sewage efficiency, the applicant applied for an application number of 03124743.1, titled as a patent for a cyclone-type sewage suction device, which is installed on the sewage inlet at the bottom of the conical sewage suction pipe, with a plurality of air pipes welded betwee...

Problems solved by technology

[0002] The irrigation rivers around the town and the underground sewage pipes in the town are often blocked due to the deposition of sediment and insoluble substances, causing the river bed to rise and the sewage to overflow, which brings many troubles to the urban sanitation departments in various places

In order to overcome the original and backward status of the existing sewage equipment, and some anti-blocking wind-powered sewage equipment have low sewage suction and poor sewage efficiency, the applicant applied for an application number of 03124743.1, titled as a patent for a cyclone-type sewage suction device, which is installed on the sewage inlet at the bottom of the conical sewage suction pipe, with a plurality of air pipes welded between the upper and lower circular fixing plates and the two fixing plates. The air distribution bag on the air inlet of the air pipe is composed of an external blower on the air inlet of the air distribution bag, so that the air blown in will form a powerful whirlwind after passing through multiple conical air pipes, and blow out from the air pipe mouth, blowing the water in the sewer The sludge and dirty water are sprayed to the designated position together with the high-speed swirling airflow

In practice, it is found that the jet force of the sewage suction device is not very strong, and the rotating wind force formed is not ideal enough, so that some insoluble substances such as bricks and heavy objects in the sludge water cannot be sucked, which affects the suction of the sewage suction device. work efficiency
