Garbage filter cartridge for raw water pipeline

Abstract

The invention discloses a garbage filter cartridge for a raw water pipeline, and belongs to the technical field of raw water pipelines, the garbage filter cartridge comprises a filter pipe, a drain pipe, a blow-off pipe, a water suction pipe and a driving box, the filter pipe is internally provided with a fold-line-shaped filter screen, the turning point position of the filter screen is provided with a first hinge component, the first hinge component is connected with a swing rod, and the swing rod is connected with the driving box. A lifting rod is hinged to the top end of the swing rod, and a driving mechanism used for driving the lifting rod to ascend and descend is arranged in the driving box. A sealing plate is hinged to one end of the filter screen corresponding to the side where the blow-off pipe is located through a first hinge member; the front and rear end faces of the filter screen and the sealing plate are attached to the inner walls of the corresponding sides of the filter pipe. By means of the suction force of the water suction pump, garbage can be intercepted and automatically discharged, the effect of cleaning the filter holes in the filter screen can be achieved, and the situation that the interior of a pipeline is blocked and the water suction pump is damaged due to the fact that the garbage enters the interior of the drainage pipe is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of raw water pipelines, in particular to a garbage filter cartridge for raw water pipelines. Background technique [0002] Raw water refers to untreated water. In a broad sense, the water before entering the water treatment process is also called the raw water of the water treatment process. For example, the water sent from the water source to the water treatment plant is called raw water, which is taken from natural water bodies or water storage bodies, such as rivers, lakes, ponds or underground aquifers, and used as water supply sources; or refers to the water that flows into the water treatment plant The water of the first treatment unit, the pipeline that transports the raw water is called the raw water pipeline.

[0003]The long-distance water transmission project is an effective measure to alleviate the shortage of urban water supply. Studies have shown that biofilms will grow on the walls of long-distance water transmission pipelines that have been in operation for a long time, and biological Microorganisms such as heterotrophic bacteria and nitrifying bacteria in the membrane need to absorb nutrients from water in order to meet their own growth needs. , the existing pumping pipes are generally directly inserted into rivers, lakes or ponds through a circular pipe to extract water. When the pumping process is easy to suck the garbage or shell vegetables inside the water body into the interior, resulting in raw water pipes The interior deteriorates the water quality and endangers the safety of the water supply system. At the same time, garbage can easily affect the pumping equipment, making it inconvenient to use
