Although the existing filter pipe can achieve basic filtering functions during actual use, after filtering natural gas for a long time, the solid impurities in the natural gas will clog the filter. At this time, the natural gas needs to be turned off and the pipe needs to be manually opened to clean the solid impurities clogged in the filter. The operation is relatively complicated and affects the continuity of natural gas transportation. Therefore, it needs to be improved. Utility Model Content

[0023] When the drive motor 2 is running, the rotating shaft 3 will drive the rotating block 4 to rotate, and then the circular shaft 5 will rotate to drive the rectangular block 6 and the first sealing plate 7 to move downward, so that the first filter screen 8 will move downward to replace the second filter screen 10, thereby achieving the purpose of continuous filtration of natural gas.

[0024] The first filter 8 and the second filter 10 are both filled with activated carbon 12 . There are two activated carbons 12 , and the two activated carbons 12 have the same size.

[0025] Since the activated carbon 12 has a rich pore structure and a huge specific surface area, it can effectively adsorb solid particles in natural gas and improve the purity of natural gas.

[0026] The left and right sides of the connecting pipe 1 are respectively fixedly connected with an air intake pipe 13 and an exhaust pipe 14 , and the outer sides of the air intake pipe 13 and the exhaust pipe 14 are fixedly connected with mounting blocks 15 .

[0027] Such a design facilitates the connection of the air intake pipe 13 and the exhaust pipe 14 via the mounting block 15 .

[0028] The outer surfaces of the air intake duct 13 and the exhaust duct 14 are both fixedly sleeved with a protection box 16 , and the protection box 16 has a rectangular appearance.

[0029] The design of the protective box 16 serves to seal and protect the first filter 8 and the second filter 10, preventing external dust from entering the first filter 8 and the second filter 10, thereby affecting the filtering effect of the first filter 8 and the second filter 10.

[0030] The top of the protection box 16 is fixedly connected to a pneumatic cylinder 17 , and the front of the pneumatic cylinder 17 is fixedly connected to a movable plate 18 .

There are two baffles 20, and the backs of the two baffles 20 are movably connected to the front of the protective box 16.

[0033] The two connecting rods 19 rotate to drive the two baffles 20 to move toward each other, thereby achieving the purpose of automatically closing the protection box 16.

[0034] Among them, the top and bottom of the front of the protection box 16 are both provided with a slide groove 21, the inner surface of the slide groove 21 is movably connected to the limit block 22, and the front of the limit block 22 is fixedly connected to the back of the baffle 20.

[0035] The design of the sliding groove 21 and the limiting block 22 serves to limit the baffle 20 .

[0036] The working principle and use process of this utility model:

[0037] When a large amount of solid particles are adsorbed inside the second filter 10, the filtering effect of natural gas will be affected. At this time, starting the drive motor 2 will cause the rotating shaft 3 to drive the rotating block 4 to rotate, and then the circular shaft 5 will rotate to drive the rectangular block 6 and the first sealing plate 7 to move downward, so that the first filter 8 moves downward to replace the second filter 10, ensuring the continuity of natural gas transportation and facilitating the cleaning of the second filter 10 for subsequent use.

[0038] In order to prevent external dust and impurities from being adsorbed into the inside of the first filter 8 and the second filter 10, they need to be sealed and protected. At this time, starting the pneumatic cylinder 17 will drive the movable plate 18 to move backward, and then the two connecting rods 19 will drive the two baffles 20 to move toward each other, thereby achieving the purpose of automatically closing the protective box 16.
