Description

Technical Field

[0001] This utility model relates to the field of natural gas filtration technology, specifically a natural gas filter separator. Background Technology

[0002] Natural gas filtration refers to the removal of solid impurities and liquid moisture from natural gas through filtration devices. This ensures that natural gas is not contaminated during transportation, storage, and use, reduces equipment damage, extends equipment life, and guarantees the safety and efficiency of the gas. Common contaminants in natural gas include dust, sand, liquid water, oil, and other minute impurities, which may originate from the production, storage, and transportation processes of natural gas.

[0003] Referring to patent publication number CN217220698U, a natural gas filter separator includes a separation tank. The interior of the separation tank is divided into a filter box, a channel, and a separation chamber from left to right. An air inlet is located above the filter box in the separation tank. A filter bag is installed inside the air inlet. A groove is formed along the edge of the air inlet, and a locking block is fixedly connected inside the groove. A bag ring is fixedly connected to the edge of the filter bag, and a locking groove matching the locking block is formed on the edge of the bag ring. By installing a filter bag inside the air inlet, impurities in the natural gas are pre-filtered through the filter bag before being filtered by the filter element, preventing impurities in the natural gas from damaging the filter element.

[0004] While the above solution can filter natural gas, it still has some shortcomings. For example, it is not convenient to disassemble and replace the filter element during use, which can lead to the filter element becoming clogged with impurities after long-term use, thus affecting the filtration of natural gas.

[0005] Based on this, the present invention designs a natural gas filter separator to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 This utility model provides a technical solution: a natural gas filter separator, including an inlet pipe 1, a connecting component 2 on the right side of the inlet pipe 1, a sealing component 3 inside the connecting component 2, and a filter component 4 inside the connecting component 2.

[0025] Please see Figure 1 and Figure 2 The connecting component 2 includes two housings 201. A set of support rods 202 are fixedly installed on the side of the two housings 201 that are close to each other. Both sides of the two housings 201 that are close to each other have openings 203 and guide grooves 204. The right end of the air intake pipe 1 is fixedly installed and connected to the left side of one of the housings 201. Through the two housings 201, the device can be connected to the air intake pipe 1 and the exhaust pipe 102, so that the gas can flow inside the device.

[0026] Please see Figure 2 and Figure 3 The sealing assembly 3 includes two threaded holes 301 on the upper surfaces of the two housings 201. A threaded rod 302 is threadedly installed on the inner top wall of each threaded hole 301. Two partitions 307 are fixedly installed on the inner wall of each housing 201. Two piston plates 305 are provided between the two sets of partitions 307. A connecting plate 304 is fixedly installed on the upper surface of each piston plate 305. Two tension springs 306 are fixedly installed on the upper surface of each connecting plate 304. The top ends of the two sets of tension springs 306 are fixedly installed to the inner top walls of the two housings 201 respectively. The tension springs 306 can apply tension to the connecting plate 304. Under the action of the threaded rod 302 and the threaded hole 301, the threaded rod 302 can push the connecting plate 304 downward, so that the connecting plate 304 can push the piston plate 305 to seal the intake pipe 1 and the exhaust pipe 102.

[0027] Please see Figure 4The filter assembly 4 includes an arc-shaped plate 401 mounted on one side of two housings 201 that are close to each other. Two perforated control blocks 402 are fixedly mounted on the outer surface of the arc-shaped plate 401. A connecting cylinder 403 is slidably mounted inside the two guide grooves 204. A filter element 408 is threadedly connected to the inner wall of the connecting cylinder 403. Grooves 405 are provided on both the left and right sides of the connecting cylinder 403. A set of springs 409 is fixedly mounted on the inner wall of each groove 405. Two guide rings 406 are fixedly mounted on the opposite ends of the two sets of springs 409. Each component is fixedly equipped with a sealing ring 407. A connecting seat 404 is fixedly installed on the outer surface of the connecting cylinder 403. Two perforated control blocks 402 are fixedly installed to the connecting seat 404 by two sets of bolts. By rotating the bolts, the perforated control blocks 402 and the connecting seat 404 can be separated, allowing the connecting seat 404 to move downwards along the connecting cylinder 403, thus enabling the connecting cylinder 403 to be disassembled. This allows the operator to replace the filter element 408. At the same time, under the action of the spring 409 and the guide ring 406, the sealing ring 407 can contact the guide groove 204, improving the sealing effect of the device.

[0028] Please see Figure 4 A handle 410 is provided below the connecting seat 404. The upper surface of the handle 410 is fixedly installed with the bottom surface of the connecting seat 404. The handle 410 makes it convenient for workers to pull the connecting cylinder 403.

[0029] Please see Figure 2 Each housing 201 has a baffle 303 fixedly installed on its inner side. The upper surfaces of the two baffles 303 are in contact with the bottom surfaces of the two piston plates 305 respectively. The baffles 303 can limit the piston plates 305 and prevent the piston plates 305 from moving downward too much.

[0030] Please see Figure 1 An exhaust pipe 102 is fixedly installed on the right side of another housing 201. A mounting base 101 is fixedly installed on the outer surface of the exhaust pipe 102 and the outer surface of the intake pipe 1. The two mounting bases 101 are fixedly installed on the side that is close to each other and on the side that is far away from each other. The mounting bases 101 can reinforce the exhaust pipe 102 and the intake pipe 1 to prevent loosening.

[0031] Please see Figure 1 Warning stickers 103 are fixedly installed on the front of the housing 201. The warning stickers 103 can warn non-staff members and prevent them from operating the device.

[0032] The implementation principle of a natural gas filter separator according to an embodiment of this application is as follows: First, the control valve connecting the inlet pipe 1 and the exhaust pipe 102 is closed to prevent the flow of natural gas. Then, the threaded rod 302 is rotated, causing it to push the connecting plate 304 to rotate. The connecting plate 304 can push the piston plate 305 downwards, thereby sealing the inlet pipe 1 and the exhaust pipe 102 and reducing natural gas leakage. Next, the bolt is rotated to separate the connecting seat 404 from the arc plate 401, and the handle 410 is pulled, causing the connecting cylinder 403 to move downwards along the guide groove 204, thus disassembling the connecting cylinder 403. Then, the filter element 408 is replaced by the operator. After replacement, the sealing ring 407 is pushed into the groove 405, and then the connecting cylinder 403 is placed into the guide groove 204. The disassembly steps are then reversed to install the device, completing the replacement of the filter element 408.
