Problems solved by technology

[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

Embodiment 1

[0025] Such as Figure 1-Figure 3 The shown garbage filter cartridge for raw water pipelines includes a filter pipe 1, a drain pipe 3 connected to one end of the top of the filter pipe 1, and a sewage discharge pipe 15 and a water suction pipe 11 connected to both ends of the bottom of the filter pipe 1, wherein the sewage discharge pipe 15 is located on the same side as the drain pipe 3, a drive box 10 is installed on the top of the filter pipe 1, and a broken line filter screen 12 is arranged inside the filter pipe 1, and the turning point of the filter screen 12 is provided with a first A hinged member 13, the turning point of the filter screen 12 is connected with a vertically arranged swing rod 14, the swing rod 14 can swing in the left and right direction, the top of the swing rod 14 is connected with a third hinged member 21 The elevating rod 6 that runs through the top of the filter pipe 1, the inside of the drive box 10 is provided with a drive mechanism for driving t...

Embodiment 2

[0027] The difference between this embodiment and embodiment 1 is:

[0028] In this example, if figure 1 and image 3 As shown, the drainpipe 3 is provided with a first sealing plug 5 at the position where the crankshaft connecting rod 9 passes through, and the top of the filter pipe 1 is provided with a second sealing plug at the position where the elevating rod 6 passes through. 19. The first sealing plug 5 and the second sealing plug 19 can prevent water from entering the drive box 10 . The sealing plate 2 is arranged obliquely, and the upper and lower ends of the sealing plate 2 are in close contact with the inner wall of the filter tube 12 . The upper end of the first hinge member 13 at the connection end of the sealing plate 2 and the filter screen 12 is connected with a vertical telescopic rod 22 , and the upper end of the telescopic rod 22 is rotatably connected with the inner top of the filter pipe 1 through the third hinge member 21 .

[0029] Others are with emb...

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] Long-distance water transmission projects are effective measures to alleviate the shortage of urban water supply. Studies have shown that biofilms will grow on the walls of long-dista...
