Embodiment 1

[0031] refer to figure 1 A pipeline filter device shown, including

[0032] A filter tube 3, the filter tube 3 is a cylindrical structure with one end closed, and the side wall of the filter tube 3 is provided with through holes;

[0033] A filter part, the filter part is connected to the inner side wall of the open port of the filter tube 3;

[0034] A propulsion mechanism, the propulsion mechanism is horizontally movably connected to the side wall of the closed end of the filter tube 3;

[0035] A cleaning mechanism, the cleaning mechanism is fixedly connected with one end face of the propulsion mechanism located in the filter tube 3 .

[0036] In actual use, the filter pipe 3 of the device is connected with the water inlet pipe 1 and the water outlet pipe 4, and then connected with the main input pipe after being connected. The liquid entering the water inlet pipe 1 from the input main pipe is filtered by the filter part and then enters the water outlet pipe 4 . Accordi...

Embodiment 2

[0039] refer to figure 1 The pipeline filtering device shown is different from the first embodiment in that: the inner wall of the filter tube 3 is provided with a chute 14 symmetrically along the axial direction; the cleaning mechanism is provided with a chute 14 matching block, the slider is placed in the chute 14 and there is a gap between the slider and the chute 14 .

[0040] In actual use, the inner walls on both sides of the filter tube 3 are provided with chute 14 symmetrically along its axial direction, and the cleaning mechanism is provided with a slide block matching the chute 14. The slider provided on the mechanism moves along the slide groove 14 . Adopting the technical solution of the chute and the slide block not only has a better position limiting effect on the cleaning mechanism, but also facilitates the cleaning mechanism to move back and forth along the chute 14 .

[0041] The technical scheme that the slider is placed in the chute 14 and there is a gap b...

Embodiment 3

[0043] refer to figure 1 The shown pipeline filtering device is different from Embodiment 1 in that: the cleaning mechanism includes a movable plate 7 and a cleaning piece; a plate surface of the movable plate 7 is connected with a propulsion mechanism, and the movable plate 7 The other plate surface is fixedly connected with the cleaning part; a slide block is arranged on the side wall of the movable plate 7, and a groove is arranged in the center of the plate surface where the movable plate 7 is connected with the propulsion mechanism.

[0044] In actual use, under the action of the propulsion mechanism, the sliding block on the movable plate 7 moves along the chute on the filter tube 3 and gradually approaches the filter part, and the surface of the filter part is cleaned by the cleaning element.

[0045] The groove provided in the center of the plate surface where the movable plate 7 is connected to the propulsion mechanism is used for contacting and connecting with the en...

Abstract

The invention belongs to the technical field of pipeline filtering, and particularly relates to a pipeline filtering device and system, a method and application. A filtering pipe of which one end is of a closed cylindrical structure and the side wall is provided with a through hole, a filtering part which is connected to the inner side wall of the port of the open end of the filtering pipe, a propelling mechanism which is horizontally and movably connected to the side wall of the closed end of the filtering pipe, and a cleaning mechanism which is fixedly connected with the end face of the end,located in the filtering pipe, of the propelling mechanism are organically arranged so that the passing liquid is filtered and filtered impurities are also collected and cleaned. The filter screen isdredged and cleaned while filtering is performed so that the filter screen is kept in a good filtering state, and actual use is facilitated.

Description

technical field [0001] The invention belongs to the technical field of water supply pipelines, and in particular relates to a pipeline filtering device, system, method and application. Background technique [0002] At present, urban water supply mainly draws surface water, reservoirs, rivers, lakes, and groundwater through the water intake pumping station of the water plant, and is processed through sedimentation, disinfection, filtration and other technological processes, and finally delivered to various users through the water distribution pumping station and pipeline network. [0003] The water in the water supply pipeline often produces impurities again during the circulation process. These impurities mainly come from the particles formed by the long-term deposition of impurities in a small amount of tap water, and the corrosion and shedding blocks formed by the long-term disrepair of the tap water pipes. A filtering mechanism is set in the pipeline to filter the water. ...
