[0021] In order to more clearly understand the above objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0022] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1: As Figures 1-6As shown in the figure, the present utility model provides a technical solution: a natural gas pipeline filter, which includes a filter assembly 1. Installation assemblies 2 are arranged at both ends of the filter assembly 1, and a filter element assembly 3 is arranged inside the filter assembly 1. The filter assembly 1 includes a filter housing 101. The filter element assembly 3 includes a mounting frame 301. A filter element 302 is installed inside the mounting frame 301. An activated carbon box 303 is installed inside the mounting frame 301. A connecting block is installed on the side of the mounting frame 301. A threaded rod 306 is threadedly connected inside the connecting block. A motor 307 is installed at the bottom of the threaded rod 306. A mounting block 304 is installed on the side of the mounting frame 301. A plurality of guiding blocks 305 are distributed inside the filter housing 101. The mounting block 304 moves inside the guiding blocks 305. Slide grooves 102 are installed on both sides of the filter housing 101. A cover plate 103 is movably installed inside the slide grooves 102. A sealing gasket 308 is installed on the top of the filter housing 101.

[0024] In this embodiment, when it is necessary to maintain and replace the filtering components inside the filter housing 101, by moving the cover plate 103 to move inside the slide groove 102, it is convenient to open the filter housing 101. Then, the motor 307 is used to drive the threaded rod 306 to rotate electrically, thereby driving the mounting frame 301 to lift. The mounting block 304 moves inside the guiding blocks 305, which is beneficial to provide a guiding effect and facilitate the overall lifting of the filter element assembly 3, and further facilitates the maintenance and replacement of the filter element 302 and the activated carbon box 303. There is no need for complex disassembly operations, which improves the convenience of operation, shortens the replacement time, and further improves the maintenance efficiency. The filter element 302 is beneficial to filter large particles inside the natural gas, and the activated carbon box 303 is beneficial to adsorb fine particles and molecules in the natural gas, making the passing natural gas purer and improving the filtering efficiency.

[0025] Embodiment 2: As Figures 1-6 shown, the installation assembly 2 includes a natural gas pipeline 201. A first docking plate 202 is installed at one end of the natural gas pipeline 201. A clamping ring 203 is installed on the side of the first docking plate 202. Connecting pipes 104 are connected to both ends of the filter housing 101. A second docking plate 205 is installed at one end of the connecting pipe 104. A clamping member 206 is installed on the side of the second docking plate 205. The clamping ring 203 is clamped inside the clamping member 206. A second sealing ring 209 is installed on the surface of the first docking plate 202. A first sealing ring 207 is installed on the surface of the second docking plate 205. The second sealing ring 209 is installed inside the first sealing ring 207. Mounting plates 204 are installed on the sides of both the first docking plate 202 and the second docking plate 205. Bolts 208 penetrate through the mounting plates 204.

[0026] In this embodiment, by clamping the snap ring 203 inside the clamping member 206, the second sealing ring 209 is clamped inside the first sealing ring 207, facilitating the connection between the first docking plate 202 and the second docking plate 205. The second sealing ring 209 and the first sealing ring 207 are conducive to providing a sealing effect and avoiding natural gas leakage. Finally, the bolt 208 is passed through the inside of the mounting plate 204, which is conducive to limiting the first docking plate 202 and the second docking plate 205. The operation is convenient, facilitating the connection and installation of the filter assembly 1 to the pipeline. There is no need for complex installation steps and professional tools, saving installation time and improving work efficiency. At the same time, it is convenient to maintain and repair the filter assembly 1 at any time.

[0027] The working principle of this embodiment: When in use, first clamp the snap ring 203 inside the clamping member 206, so that the second sealing ring 209 is clamped inside the first sealing ring 207, facilitating the connection between the first docking plate 202 and the second docking plate 205. The second sealing ring 209 and the first sealing ring 207 are conducive to providing a sealing effect. Finally, pass the bolt 208 through the inside of the mounting plate 204, which is conducive to limiting the first docking plate 202 and the second docking plate 205, facilitating the installation of the pipeline to the filter assembly 1. Then, natural gas enters the inside of the filter housing 101 through the natural gas pipeline 201. The filter element 302 is conducive to filtering large particles inside the natural gas, and the activated carbon box 303 is conducive to adsorbing fine particles and molecules in the natural gas. When it is necessary to maintain and replace the filter components inside the filter housing 101, by moving the cover plate 103 inside the sliding groove 102, it is convenient to open the filter housing 101. Then, the motor 307 is electrically driven to rotate the threaded rod 306, thereby driving the mounting frame 301 to rise. The mounting block 304 moves inside the guiding block 305, which is conducive to providing a guiding effect and facilitating the overall rising of the filter element assembly 3, facilitating the maintenance and replacement of the filter element 302 and the activated carbon box 303.
