Automatic flushing device for inclined pipe of horizontal flow sedimentation tank

Abstract

The invention provides an automatic flushing device for an inclined pipe of a horizontal flow sedimentation tank. The automatic flushing device comprises an aeration pipe, a steel wire rope hoisting mechanism, a steel wire rope, a walking trolley, a walking track, an inclined pipe bracket beam, the inclined pipe, a synchronous detection device, an air conveying hose guide wheel, an air conveying hose, an air conveying hose hoisting mechanism and a controller; the walking trolley is arranged at the bottom of the sedimentation tank and installed on the walking track, the aeration pipe is installed on the walking trolley, a steel wire rope pulls the walking trolley to do reciprocating linear motion along the walking track so as to drive the aeration pipe to move in the tank length direction, and pressure air is conveyed to the aeration pipe through the air conveying hose. Exhaust holes in the aeration pipe are uniformly distributed in water, the sludge accumulated on the inclined pipe is rubbed during the floating process of the bubbles so as to make the sludge loose and slide down, and thus the purpose of washing is achieved. The inclined pipe can be washed while the sedimentation tank operates in the non-water-cut-off state so as to ensure the normal operation of the sedimentation tank, te use efficiency of the sedimentation tank is effectively improved, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to an automatic flushing device for inclined pipes of an advection sedimentation tank. Background technique [0002] Advection sedimentation tanks are widely used in the water treatment industry. In order to improve efficiency, inclined plates and pipes are often added to the sedimentation tanks, hereinafter referred to as inclined pipes. However, in long-term operation, some sludge will accumulate on the inclined pipe and affect the treatment effect, so regular flushing is required. The existing technology is to stop the water and lower the water level below the inclined pipe, and use high-pressure flushing water for flushing, which not only reduces the use efficiency of the sedimentation tank, affects the normal operation of the overall water treatment system, but also increases the labor intensity of workers and wastes water resources.

However, in long-term operation, some sludge will accumulate on the inclined pipe and affect the treatment effect, so regular flushing is required

The existing technology is to stop the water and lower the water level below the inclined pipe, and use high-pressure flushing water for flushing, which not only reduces the use efficiency of the sedimentation tank, affects the normal operation of the overall water treatment system, but also increases the labor intensity of workers and wastes water resources
