[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figures 1 to 4 As shown, a natural gas compressor pipeline filter device has an inlet end 3 at one end of the filter device housing 1 and an outlet end 5 at the other end. The inlet end 3 is detachably mounted on its inner side, and a fixing ring 10 is fixedly mounted thereon. A plurality of filter holes 4 are provided through the filter plate 2. A guide ring 14 is fixed to the surface of the filter plate 2 facing the fixing ring 10. The surface of the guide ring 14 has a circular array of arc-shaped protrusions and arc-shaped grooves, which are spaced apart and tangent to each other. The fixing ring 10... A rubber elastic ring 11 is bonded and fixed to the surface of the filter plate 2. A rotating strip 12 is provided between the rubber elastic ring 11 and the guide ring 14. The rotating strip 12 is equipped with bristles on the surface of the filter plate 2. A connecting rod 6 is provided on the inner side of the gas outlet 5. One end of the connecting rod 6 is slidably connected to the rotating strip 12. Multiple rotating threaded blades 7 are fixed in a circular array on the outer surface of the other end of the connecting rod 6. When natural gas flows inside the gas outlet 5, it pushes the rotating threaded blades 7 and the connecting rod 6 to rotate, so that the rotating strip 12 rotates and clears the inside of the filter hole 4 through the bristles.

[0023] Both ends of the rotating strip 12 are embedded with contact balls 13 on the surface facing the guide ring 14. The rotating strip 12 and the guide ring 14 are in rolling contact through the contact balls 13. The inner side of the rubber elastic ring 11 is hollow and filled with gas. When the contact balls 13 roll against the surface of the guide ring 14, the distance between the rotating strip 12 and the filter plate 2 changes during the rotation due to the arc-shaped protrusions and grooves on the surface of the guide ring 14, and the rubber elastic ring 11 is compressed. The compressed rubber elastic ring 11 provides a reverse force to the rotating strip 12, ensuring that the contact balls 13 are always in contact with the guide ring 14. This allows the rotating strip 12 to move back and forth towards the filter plate 2 during the rotation. The bristles on the surface of the rotating strip 12 move axially through the filter holes 4 to unclog the filter holes 4.

[0024] The rotating strip 12 is provided with a sliding insertion hole 15 in the middle of the surface of the fixed ring 10, one end of the connecting rod 6 is inserted into the inner side of the sliding insertion hole 15, the inner wall of the sliding insertion hole 15 is provided with two symmetrical strip-shaped sliding grooves, the end of the connecting rod 6 inserted into the outer side of the sliding insertion hole 15 is fixed with two guide pieces 16, the guide pieces 16 are slidingly connected to the inner side of the strip-shaped sliding grooves, so that the connecting rod 6 can drive the rotating strip 12 to rotate at the same time when the connecting rod 6 rotates, and the rotating strip 12 can move along the axial direction of the connecting rod 6 and will not be separated from the connecting rod 6.

[0025] The inner surface of the gas outlet end 5 is provided with a positioning ring groove 9, and the end of the connecting rod 6 located in the inner side of the gas outlet end 5 is detachably mounted with a positioning strip 8, both ends of the positioning strip 8 are arc surfaces, and both ends of the positioning strip 8 are slidingly connected to the inner side of the positioning ring groove 9, so that the connecting rod 6 is supported and positionally limited by the positioning strip 8, and the connecting rod 6 will not move along the axial direction thereof during the rotation of the connecting rod 6.

[0026] Working principle: first, natural gas is sent from the gas inlet end 3 into the filter device shell 1, and the natural gas passes through the filter plate 2 into the inner side of the gas outlet end 5, when the natural gas passes through the filter plate 2, the filter plate 2 intercepts and filters the impurities in the natural gas, and after the filtered natural gas enters the inner side of the gas outlet end 5, the rotating screw blade 7 on the outer surface of the connecting rod 6 is pushed, so that the rotating screw blade 7 drives the connecting rod 6 to rotate, at this time, the connecting rod 6 drives the rotating strip 12 to rotate at the same time through the guide piece 16, the rotating strip 12 drives the contact ball 13 to roll along the surface of the guide ring 14 when rotating, when the contact ball 13 rolls along the surface of the guide ring 14, because the surface of the guide ring 14 has an arc protrusion and an arc groove, the distance between the rotating strip 12 and the filter plate 2 changes during the rotation of the rotating strip 12 and the rubber elastic ring 11 is compressed, and the compressed rubber elastic ring 11 provides a reverse force to the rotating strip 12, so that the contact ball 13 is always in contact with the guide ring 14, so that the rotating strip 12 reciprocally approaches or moves away from the filter plate 2 during the rotation, the bristles on the surface of the rotating strip 12 axially penetrate and move in the filter hole 4, so as to dredge the filter hole 4 and ensure that the natural gas conveying is not affected.

[0027] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
