[0036] Combination Figures 1 to 6 As shown in the figure, the embodiment provides a filter separator for processing natural gas, which comprises a shell assembly 1, a filter unit 2, a fixing mechanism 3 and a moving mechanism 4.

[0037] Specifically, referring to Figure 1 As shown in the figure, the shell assembly 1 comprises a shell 11 and a cover plate 12, a partition plate 13 is arranged in the shell 11, the partition plate 13 divides the cavity composed of the shell 11 and the cover plate 12 into a filter chamber 111 and an exhaust chamber 112, a passage capable of connecting the filter chamber 111 and the exhaust chamber 112 is arranged on the partition plate 13, an air inlet 113 and an exhaust port 114 are arranged above the shell 11 and communicate with the filter chamber 111, so that the excess natural gas discharged from the exhaust port 114 can continue to enter the filter chamber 111 from the air inlet 113 for filtering and separation, thereby saving cost. An air outlet 115 is arranged on the shell 11 and communicates with the exhaust chamber 112. The filter chamber 111 is provided with an opening at one end away from the partition plate 13 for cooperating with the cover plate 12, and the cover plate 12 is preferably a quick-opening blind plate, so as to facilitate opening or closing the filter chamber 111. In addition, in the embodiment, a blowdown pipe 5 is arranged at the bottom of the filter chamber 111 and the exhaust chamber 112, so as to discharge the filter residue and waste liquid obtained after filtering in the filter chamber 111 and the exhaust chamber 112.

[0038] In the embodiment, the filter separator is a horizontal device, and in order to meet the requirements under actual working conditions, the filter separator further comprises a supporting leg 6 arranged at the bottom of the shell 11, and one of the above-mentioned supporting legs 6 is arranged at the bottom of the filter chamber 111 and the exhaust chamber 112, so as to ensure that the entire filter separator is stable, and the filter separator device has good stability and levelness on different grounds.

[0039] Combination Figures 1 to 4 As shown in the figure, the filter unit 2 is arranged in the filter chamber 111 and is used for filtering and impurity separation of the natural gas in the filter chamber 111. Specifically, the filter unit 2 provided by the embodiment comprises a filter plate 21 and a filter core 22, wherein the filter plate 21 is arranged in the filter chamber 111, the filter core 22 is installed on the filter plate 21 and can be detachably fixedly connected with the filter plate 21 through the fixing mechanism 3. It should be noted that the number of the filter core 22 is not limited by the utility model, and the number of the filter core 22 can be flexibly adjusted according to actual requirements. Exemplarily, in the embodiment, seven filter cores 22 are annularly installed on the filter plate 21.

[0040] Specifically, in the embodiment, the filter plate 21 comprises a first filter plate 211 and a second filter plate 21221 respectively arranged at both ends of the filter core 22, and the first filter plate 211 is closer to the cover plate 12 than the second filter plate 21221. A plurality of mounting holes 2111 are arranged through the first filter plate 211, and a plurality of slot holes 2121 are arranged on the second filter plate 21221. The number of the mounting holes 2111 and the slot holes 2121 is equal to the number of the filter core 22, and the mounting holes 2111 are arranged in one-to-one correspondence with the slot holes 2121. During installation, one end of the filter core 22 is inserted into the slot hole 2121, and the other end passes through the mounting hole 2111. The fixing mechanism 3 is arranged on the first filter plate 211 and can abut against the other end of the filter core 22 to stably position and fix the filter core 22 on the filter plate 21.

[0041] In order to realize the detachable connection between the filter core 22 and the filter plate 21, in the embodiment, referring to Figure 5 The fixing mechanism 3 specifically comprises a rotating shaft 31 and a clamping plate 32. The rotating shaft 31 is provided with a threaded section. A threaded hole is formed on one side of the first filter plate 211 corresponding to the mounting hole 2111. After the threaded section of the rotating shaft 31 passes through one end of the clamping plate 32, it is screwed into the threaded hole, thereby realizing the threaded rotary connection with the first filter plate 211. Through the above arrangement, when the rotating shaft 31 is screwed, the rotating shaft 31 can drive the clamping plate 32 to rotate circumferentially around the rotating shaft 31, so that the other end of the clamping plate 32 can butt joint or avoid the mounting hole 2111. In this way, when the filter core 22 is installed in place on the filter plate 21, the other end of the clamping plate 32 will abut against the filter core 22 after the rotating shaft 31 is screwed, ensuring that it is fixed.

[0042] It should be noted that in the embodiment, one fixing mechanism 3 is arranged on one side of each mounting hole 2111, so as to independently adjust and replace each filter core 22. When a filter core 22 needs to be replaced, the operator only needs to screw the clamping plate 32 of the corresponding rotating shaft 31 to make the clamping plate 32 avoid the mounting hole 2111, so as to realize the quick disassembly and installation of the filter core 22, thereby greatly improving the maintenance efficiency of the filter unit 2.

[0043] Further, the clamping plate 32 has a Z-shaped structure to enhance the structural strength of the clamping plate 32 and ensure that it is not easily deformed under certain pressure.

[0044] Optionally, the aforementioned fixing mechanism 3 further includes an elastic element 33, with its two ends connected to the first filter plate 211 and the locking plate 32, respectively. For example, in this embodiment, the elastic element 33 is a torsion spring. When the filter element 22 is pressed against the first filter plate 211 by the locking plate 32, the torsion spring is in a stretched state, allowing it to continuously provide a pulling tendency towards the locking plate 32, thereby ensuring that the locking plate 32 can provide a continuous and stable pressing force on the filter element 22, thus ensuring that the filter element 22 maintains a stable fixed state during long-term use.

[0045] Optionally, in this embodiment, an elastic sealing gasket 34, such as a rubber gasket, silicone gasket, or sponge gasket, is also attached to the side of the positioning plate 32 facing the mounting hole 2111. By setting the elastic sealing gasket 34, the tightness between the positioning plate 32 and the filter element 22 can be improved, further enhancing the stability of the fixed filter element 22. At the same time, it can also prevent the positioning plate 32 from directly contacting the filter element 22, thus avoiding damage to the filter element 22 and ensuring the safety of the filter element 22 in use.

[0046] Optionally, in this embodiment, a knob 35 is also provided at the end of the rotating shaft 31. The knob 35 has anti-slip texture. By rotating the knob 35, the rotating shaft 31 can be rotated, so as to facilitate manual operation by personnel and reduce the labor intensity.

[0047] Specifically, refer to Figure 6 As shown, the moving mechanism 4 includes a frame plate 41 and a slider 42. A groove 411 extends along the axis of the housing 11 on the frame plate 41, forming a moving track. The slider 42 is slidably mounted on the moving track and fixedly connected to the filter unit 2. In this embodiment, the filter unit 2 also includes a connecting frame 23. Both ends of the connecting frame 23 are connected to the first filter plate 211 and the second filter plate 21221, respectively. The slider 42 is connected to the end face of the connecting frame 23 via a connector, thereby enabling the slider 42 to move the entire filter unit 2. By setting the moving mechanism 4, when the slider 42 slides within the groove 411, it can move the entire filter unit 2 horizontally out of the housing 11, allowing workers to inspect the filter element 22 from outside the housing 11, reducing the workload of filter element 22 maintenance.

[0048] More specifically, the moving mechanism 4 further comprises a lead screw 43 and a driving member 44, one end of the lead screw 43 is arranged in the sliding groove 411 and is threadedly connected with the sliding block 42, the other end of the lead screw 43 is drivingly connected with the driving member 44, and in this embodiment, a fixed support 45 is used to fixedly mount the driving member 44 on the rack plate 41. When the driving member 44 is started, the lead screw 43 starts to rotate, the sliding block 42 moves along the sliding groove 411, thereby realizing the smooth moving out and moving in of the filter unit 2. Therefore, by automatically controlling the movement of the sliding block 42 through the driving member 44, the replacement and maintenance process of the entire filter unit 2 can be more automated and efficient.

[0049] In one embodiment of this embodiment, the moving mechanism 4 further comprises a first bevel gear 46 and a second bevel gear 47 which are engagedly connected, the first bevel gear 46 is connected with the output shaft of the driving member 44, the second bevel gear 47 is connected with the other end of the lead screw 43, when the driving member 44 rotates, the first bevel gear 46 engages with the second bevel gear 47, so that the lead screw 43 rotates, thereby driving the sliding block 42 to move along the sliding groove 411. In this way, the stable and precise movement of the filter element 22 can be ensured, so that the maintenance and replacement of the filter element 22 are more smooth and efficient.

[0050] Alternatively, the moving mechanism 4 provided by this embodiment further comprises an angle iron 48 and an assembly threaded part 49, the two ends of the angle iron 48 are respectively provided with an assembly hole 481, one of the assembly holes 481 is correspondingly arranged on the end face of the rack plate 41 and is threadedly connected with the rack plate 41 through an assembly threaded part 49 (such as a screw, a bolt, etc.), the other assembly hole 481 is correspondingly arranged on the inner wall of the filter chamber 111 and is threadedly connected with the inner wall of the filter chamber 111 through an assembly threaded part 49, thereby facilitating the staff to stably fix the moving mechanism 4 in the filter chamber 111.

[0051] The working principle of the filter separator provided by this embodiment is as follows:

[0052] When it is necessary to maintain the filter unit 2, the staff first opens the cover plate 12, and then starts the driving member 44, the output shaft of the driving member 44 drives the lead screw 43 to rotate through the first bevel gear 46 and the second bevel gear 47, the lead screw 43 drives the sliding block 42 to slide horizontally in the sliding groove 411, the sliding block 42 drives the plurality of filter elements 22 to move horizontally through the connecting frame 23, the first filter plate 211 and the second filter plate 21221, so that the plurality of filter elements 22 are horizontally moved out of the filter chamber 111, thereby conveniently realizing the overall moving out of the filter unit 2, and further facilitating the staff to maintain the filter elements 22.

[0053] When several filter cartridges 22 need to be replaced, the staff manually rotates the corresponding knob 35, the knob 35 rotates the rotating shaft 31, the rotating shaft 31 makes the clamping plate 32 and the elastic sealing pad 34 revolve around the axis of the rotating shaft 31 as the center, so that the clamping plate 32 and the elastic sealing pad 34 release the limiting of the filter cartridge 22. Then, the staff pulls out the filter cartridge 22 from between the first filter plate 211 and the second filter plate 21221, thereby conveniently realizing the disassembly of the filter cartridge 22, and effectively improving the convenience of the maintenance or replacement of the filter cartridge 22, and reducing the working strength of the staff.
