The surface of the fixing plate 11 is evenly provided with limiting holes 12 for the filter element 7 to pass through, and a limiting ring 13 is installed on the inner wall of the limiting hole 12 on the surface of the fixing plate 11 on the inner side of the mounting ring B9. The cross-section of the limiting ring 13 is triangular, and the surface of the limiting ring 13 is pressed and fitted with the side surface of one end of the filter element 7, so that the filter element 7 can be disassembled and cleaned conveniently, and multiple can be selected for disassembly and cleaning together or individually, which is convenient and quick to operate, with good flexibility and high practicality.

[0022] like Figure 2 and Figure 4As shown, a sealing assembly is provided on the inner surface of the end cover 2, and the sealing assembly includes a sealing gasket 14 installed on one end surface of the filter tank 1, and a sealing groove 15 for the sealing gasket 14 to engage is opened on the inner surface of the end cover 2, and a rubber ring 16 is fixed inside the sealing groove 15, and the surface of the sealing gasket 14 facing the rubber ring 16 is raised, and the surface width of the rubber ring 16 is equal to the width of the opening of the sealing groove 15, and mounting magnetic sheets 17 are installed at equal distances on the inner surface of the rubber ring 16 and the inner surface of the sealing groove 15, and the mounting magnetic sheets 17 on the inner surface of the rubber ring 16 have the same magnetic properties as the mounting magnetic sheets 17 on the inner surface of the sealing groove 15, so as to improve the sealing performance of the connection between the end cover 2 and the filter tank 1, so that natural gas is not prone to leakage during the filtration process, and the practical effect is better.

[0023] The utility model provides a natural gas filtering and separating device, and the specific working principle is as follows: when the filter element 7 is installed in the early stage, the installation ring A8 and the installation ring B9 are first pushed to move inside one end of the filter tank 1, so that the installation ring A8 and the installation ring B9 can be limited and engaged at one end of the inner part of the filter tank 1 through the connecting rod 10, and then the filter element 7 is pushed to move inside the filter tank 1 one by one, so that one end of the filter element 7 is aligned with the opening of the limiting plug hole 12 on the surface of the fixing plate 11 inside the installation ring A8, and at this time, one end of the filter element 7 is passed through the inside of the limiting plug hole 12, so that the filter element One end of the filter element 7 moves toward the inner side of the mounting ring B9 until one end of the filter element 7 penetrates and engages with the inside of the limiting plug hole 12 on the surface of the fixing plate 11 inside the mounting ring B9.
