Embodiment 1

[0024] like Figure 1 to Figure 4 In the shown embodiment, a natural gas filter device for seamlessly replacing the filter screen 3 includes a filter plate 2 inside the natural gas pipeline 1, a filter screen 3 inside the filter plate 2, the filter plate 2 includes a plate shell 4, and the natural gas The pipe 1 is provided with a through opening for inserting the filter plate 2. The filter plate 2 is provided with a filter cavity 5 for placing the filter screen 3 and the filter screen support frame 6. The filter plate 2 is provided with a filter cavity 5 for closing the filter screen cavity. A pair of closing plates, the closing plate is adapted to the shape of the mouth of the filter chamber 5; the edge of the closing plate is provided with a sealing ring. The closing plate is used to fill the mouth of the filter screen cavity 5, and when the filter screen 3 is replaced, the surface of the filter plate 2 is smoothed, so that the filter plate 2 maintains airtightness when it ...

Embodiment 2

[0029] like Figure 5 In the shown embodiment, a natural gas filter device for seamlessly replacing the filter screen 3, in this embodiment, the structure is the same as that of Embodiment 1 except for the expansion mechanism. The expansion mechanism includes a support rod 16, a torsion spring joint 17 and limit rope 18; two poles 16 are hinged in a "V" shape, and the hinge is provided with a torsion spring joint 17; There is a limit rope 18 whose length is the inner width of the plate shell 4. Here is another solution for the expansion mechanism. The single pneumatic rod 10 is replaced by two struts. The struts 16 are folded, and the middle joint is a torsion spring joint 17, which can provide the elastic force for rotation. , the strut mechanism will have an elastic force to stretch outwards like this. The two ends of the rod mechanism are hinged to the edge of the two closed plates 9, and the two hinges are connected with a fixed-length limit rope 18, the length of which ...

Abstract

The invention discloses a natural gas filter device for seamlessly replacing the filter screen, which comprises a filter plate inside the natural gas pipeline, a through opening for inserting the filter plate in the natural gas pipeline, and a filter plate for placing a filter screen and a filter plate inside the filter plate. The filter chamber of the net support frame, the filter device can realize the replacement of the filter screen without closing the natural gas pipeline, and at the same time ensure the airtightness of the filter device. The invention has the following beneficial effects: (1) more convenient and rapid filter device replacement can be realized; (2) the filter device can be replaced when the natural gas pipeline is working.

Description

technical field [0001] The invention relates to the technical field of natural gas purification, in particular to a natural gas filter device for seamless replacement of filter screens. Background technique [0002] Now natural gas is widely used, and the use of natural gas needs to filter out the impurities in the period, and the filter device will be polluted after a long time of use, and the staff needs to clean it at this time. How to make the cleaning of the filter device more efficient, quick, time-saving and labor-saving has become an urgent problem to be solved. [0003] For example, a "filter with a replaceable filter screen" disclosed in Chinese patent literature, its announcement number CN107890723A, includes a filter, a fixing buckle, a connecting block, a connecting hole, a mesh core, a connector and a buckle block , the outer side of the filter is provided with a fixed buckle, the fixed buckle is fixedly connected with the filter, the inside of the filter is p...
