[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model provides Figure 1-5A filter separator for natural gas production and transportation shown in the figure comprises a workbench 1, a filter box 2 is fixedly connected to the top of the workbench 1, a mounting plate 201 is bolted to the top of the filter box 2, so that the mounting plate 201 is installed on the top of the filter box 2, a plurality of groups of filter screens 202 are arranged below the mounting plate 201, the air in the filter box 2 is filtered in multiple layers through the filter screens 202, an automatic cleaning mechanism 3 is arranged below the filter screens 202, and the filter screens 202 are cleaned by the automatic cleaning mechanism 3, the automatic cleaning mechanism 3 comprises a servo motor 301 fixedly connected to the bottom end of the workbench 1, a top contact plate 302 is fixedly connected to the output end of the servo motor 301, a collecting box 303 is sleeved on the outer side of the top contact plate 302 and the collecting box 303 is installed at the bottom end of the workbench 1, the top of the top contact plate 302 abuts against an ash leakage hole 304, the servo motor 301 is used to drive the top contact plate 302 to rotate, The filter screen 202 is reciprocated and lifted, so that impurities on its surface are shaken off. The bottom end of the filter box 2 is fixedly connected to a sliding seat 203, and the sliding seat 203 is located inside the collection box 303. The ash leakage hole 304 is slidably connected to the inside of the sliding seat 203. The top of the filter screen 202 is slidably connected to a sliding rod 8, and the top of the sliding rod 8 is fixedly connected to the bottom end of the mounting plate 201. The outer side of the sliding rod 8 is sleeved with a return spring 7, and the return spring 7 extends to both ends in a natural state, so that the filter screen 202 is reset after lifting. Through the cooperation of the filter box 2 and the automatic cleaning mechanism 3, when the servo motor 301 drives the top contact plate 302 to rotate, it drives the blocking plate 601 and the ash leakage hole 304 and its attached ash leakage plate to achieve shaking to shake off the dirt on its surface, so that the dirt passes through the leakage holes on the ash leakage hole 304 and enters the interior of the collection box 303 for easy collection, thereby reducing the burden on maintenance personnel.

[0025] Refer to the instruction manual Figure 1-5The top of the workbench 1 is fixedly connected with a filter separator body 4, the filter box 2 is communicated with one end of the filter box 2, and the end of the filter box 2 away from the filter separator body 4 is fixedly connected with an air inlet 5, so that the natural gas enters the interior of the filter box 2 through the air inlet 5 to be filtered, and then enters the interior of the filter separator body 4 for further purification. A pull-out plate 6 is slidably connected to one side of the workbench 1, and a baffle plate 601 is slidably connected to one side of the pull-out plate 6 located below the filter box 2, which can follow the lifting and lowering movement of the ash leakage hole 304. A plurality of through holes are opened at the position corresponding to the ash leakage hole 304. When the baffle plate 601 overlaps with the through hole of the ash leakage hole 304, impurities can be allowed to fall into the baffle plate 601. The interior of the automatic cleaning mechanism 3 is fixedly connected to the inner wall of the sliding seat 203, and a sliding groove 9 is arranged below the limiting block 10, and the sliding groove 9 corresponds to the shape of the limiting block 10, and the sliding groove 9 is opened on one side of the blocking plate 601. When the sliding groove 9 does not correspond to the limiting block 10, the limiting block 10 limits the blocking plate 601 to prevent it from disturbing the airflow in the filter box 2. Through the cooperation of the pull-out plate 6, the blocking plate 601 and the ash leakage hole 304, the automatic cleaning mechanism 3 is in a non-working state, ensuring that natural gas only passes through the filter screen 202, avoiding turbulence from entering the interior of the automatic cleaning mechanism 3, thereby reducing work consumption and improving the practicability of the structure.

[0026] How this utility works:

[0027] Refer to the instruction manual Figure 1-5When it is necessary to filter and separate the natural gas, the natural gas pipe is connected to the air inlet 5, so that it enters the interior of the filter box 2 and is initially filtered by the filter screen 202, and then further purified by the filter separator body 4. During this process, when the filter screen 202 accumulates a large amount of impurities, the position of the sliding groove 9 and the limit block 10 are overlapped, and then when the servo motor 301 is started to drive the top touch plate 302, since the ash leakage hole 304 and the ash leakage plate attached thereto are slidably connected to the interior of the sliding seat 203, and the blocking plate 601 is slidably connected to one side of the pull-out plate 6, the top touch plate 302 can drive the blocking plate 601 and the ash leakage hole 304 and the ash leakage plate attached thereto to slide together in the interior of the sliding seat 203 when the top touch plate 302 rotates, and at the same time, the gas can be filtered out by the filter separator body 4. The cooperation between the sliding groove 9 and the limit block 10 prevents the above-mentioned movement from being blocked. When the top contact plate 302 is rotated, the blocking plate 601 can be driven to slide together with the ash leakage hole 304 and its attached ash leakage plate inside the sliding seat 203, while making the multiple filter screens 202 rise and fall repeatedly, so that the natural gas above is also filtered. In addition, the impurities in the natural gas are often heavier than the natural gas itself, and are more likely to move downward and be filtered by the filter screen 202, so that the dirt passes through the leakage holes on the ash leakage hole 304 and enters the interior of the collection box 303 for easy collection, thereby reducing the replacement frequency of the sliding seat 203 and the burden on maintenance personnel. Finally, the collection box 303 is dismantled and cleaned and then reinstalled at the bottom of the workbench 1 to complete the work.

[0028] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
