Description

Technical Field

[0001] This utility model relates to the field of gas transmission and distribution technology, specifically a gas filtration device for gas transmission and distribution. Background Technology

[0002] Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere, such as oilfield gas, gas field gas, mud volcano gas, coalbed methane, and biogenic gas. However, natural gas may be mixed with impurities in pipelines during transportation, affecting its purity. Therefore, it is necessary to filter natural gas to remove impurities. Most current filters use filter screens to intercept impurities.

[0003] According to a public announcement of a natural gas transmission and filtration device (Announcement No.: CN213610403U), the above application uses a partition fixedly installed inside the valve body, an explosion-proof motor fixedly installed on the top of the valve body, a first bevel gear fixedly installed on the output shaft of the motor, a rotating rod rotatably installed inside the valve body with its top end extending outside the valve body, a second bevel gear fixedly sleeved on the rotating rod, the first bevel gear meshing with the second bevel gear, a conveying groove opened at the top of the rotating rod, a filter cylinder fixedly sleeved on the rotating rod, an air inlet pipe fixedly installed on one side of the valve body, and an exhaust fan fixedly installed on the top of the valve body. This device has the advantages of being easy to use and preventing blockages.

[0004] However, in actual use, although the above-mentioned equipment can clean and scrape the inner wall of the valve body through the comb plate, the surface of the comb plate will be covered with dirt from the pipe and fragments of the pipe wall after scraping, which will cause blockage of the subsequent filtration of the filter cartridge; in view of this, we propose a gas filtration device for gas transmission and distribution. Summary of the Invention

[0005] The purpose of this invention is to provide a gas filtration device for gas transmission and distribution to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gas filtration device for gas transmission and distribution, comprising a conveying chamber, an air inlet and an exhaust outlet on the outer wall of the conveying chamber, a top cover on the outer wall of the conveying chamber, and a waste removal assembly on the inner wall of the conveying chamber. The waste removal assembly includes a guide groove on the inner wall of the conveying chamber. A rotating rod is rotatably mounted on the inner wall of the top cover. A perforated rotating plate is fixedly connected to the end of the rotating rod. A filter cylinder is fixedly connected to the outer wall of the perforated rotating plate. A fixing sleeve is fixedly connected to the outer wall of the rotating rod. A sliding block is slidably connected to the inner wall of the fixing sleeve.

[0007] A sliding rod is fixedly connected to the outer wall of a sliding block. A rubber rod is fixedly connected to the outer wall of the sliding block. A round rubber ball is fixedly connected to the end of the rubber rod. A tough rubber plate is fixedly connected to the inner wall of the conveying chamber. A hollow groove is opened on the outer wall of the tough rubber plate. A collection chamber is detachably installed at the bottom of the conveying chamber. A hollow fixing plate is fixedly connected to the inner wall of the conveying chamber.

[0008] Preferably, the outer wall of the sliding rod is slidably connected to the inner wall of the guide groove, and the sliding rod is configured to be wave-shaped, so that the sliding rod can move smoothly on the inner wall of the guide groove.

[0009] Preferably, the discharge port of the perforated rotating plate is adapted to the discharge port of the perforated fixed plate, so that when the discharge ports of the perforated rotating plate and the perforated fixed plate overlap, the debris can be discharged into the collection bin.

[0010] Preferably, the center line of the rotating rod and the center line of the filter cartridge are on the same straight line, so that the rotating rod can smoothly drive the filter cartridge to rotate.

[0011] Preferably, the outer wall of the rotating rod is provided with a triggering component, the triggering component includes an arc-shaped top block, and the outer wall of the tough rubber plate is fixedly connected with an arc-shaped top block.

[0012] Preferably, the number of arc-shaped top blocks is several, and the several arc-shaped top blocks are arranged in a linear array on the outer wall of the rotating rod.

[0013] Compared with the prior art, the present invention provides a gas filtration device for gas transmission and distribution, which has the following advantages:

[0014] 1. This gas filtration device for gas transmission and distribution allows the filter cartridge to be cleaned by turning the rotating rod. This rotation causes the filter cartridge to rotate, allowing the tough rubber plate on the inner wall of the conveying chamber to scrape the surface of the filter cartridge. Simultaneously, the perforated rotating plate rotates, allowing debris to be discharged into the collection chamber when the perforated rotating plate overlaps with the discharge port of the perforated fixed plate. Furthermore, as the filter cartridge rotates, the sliding rod smoothly moves along the inner wall of the guide groove, causing the circular rubber ball on the rubber rod to periodically rotate and strike the tough rubber plate. This vibration causes the debris attached to the tough rubber plate to fall off, ultimately ensuring both the cleanliness of the filter cartridge and the self-cleaning of the tough rubber plate.

[0015] 2. This gas filtration device for gas transmission and distribution, when the rotating rod is turned to rotate the filter cartridge, causes the circular rubber ball on the rubber rod to periodically rotate and strike the tough rubber plate. At the same time, the tough rubber plate is also touched by the arc-shaped top block, which further vibrates the tough rubber plate, allowing the debris attached to the surface to fall off better. Furthermore, when the circular rubber ball on the rubber rod periodically rotates and strikes the tough rubber plate, the circular rubber ball is rubbed by the arc-shaped top block, which further enhances the vibration effect and ultimately improves the overall practicality.

[0023] like Figures 1-6As shown, this utility model provides a technical solution: a gas filtration device for gas transmission and distribution, including a conveying chamber 1, an air inlet 2 and an exhaust port 3 on the outer wall of the conveying chamber 1, a top cover 4 on the outer wall of the conveying chamber 1, and a waste removal component 5 on the inner wall of the conveying chamber 1. The waste removal component 5 includes a guide groove 501, which is formed on the inner wall of the conveying chamber 1. A rotating rod 502 is rotatably mounted on the inner wall of the top cover 4. A hollow rotating plate 503 is fixedly connected to the end of the rotating rod 502. A filter cylinder 504 is fixedly connected to the outer wall of the hollow rotating plate 503. A fixing sleeve 505 is fixedly connected to the outer wall of the rotating rod 502. A sliding block 506 is slidably connected to the inner wall of the fixing sleeve 505.

[0024] Furthermore, the sliding rod 507 is fixedly connected to the outer wall of the sliding block 506, the outer wall of the sliding block 506 is fixedly connected to the rubber rod 508, the end of the rubber rod 508 is fixedly connected to the round rubber ball 509, the inner wall of the conveying chamber 1 is fixedly connected to the flexible rubber plate 510, the outer wall of the flexible rubber plate 510 is provided with a hollow groove 511, the bottom end of the conveying chamber 1 is detachably installed with a collection chamber 512, and the inner wall of the conveying chamber 1 is fixedly connected to a hollow fixing plate 513.

[0025] In this embodiment of the present invention, the outer wall of the sliding rod 507 is slidably connected to the inner wall of the guide groove 501, and the sliding rod 507 is set in a wave shape, so that the sliding rod 507 can move smoothly on the inner wall of the guide groove 501. The discharge port of the hollow rotating plate 503 is adapted to the discharge port of the hollow fixing plate 513, so that when the discharge ports of the hollow rotating plate 503 and the hollow fixing plate 513 overlap, the debris can be discharged into the collection chamber 512. The center line of the rotating rod 502 and the center line of the filter cartridge 504 are on the same straight line, so that the rotating rod 502 can smoothly drive the filter cartridge 504 to rotate.

[0026] Furthermore, the outer wall of the rotating rod 502 is provided with a triggering component 6, which includes an arc-shaped top block 601. The outer wall of the flexible rubber plate 510 is fixedly connected with an arc-shaped top block 602. The number of arc-shaped top blocks 601 is several, and the several arc-shaped top blocks 601 are arranged in a linear array on the outer wall of the rotating rod 502.

[0027] In this invention, during daily use, the gas input from the air inlet 2 enters the delivery chamber 1, whereby dirt and debris from the filter pipe are blocked by the filter cartridge 504. The gas continues to be delivered through the filter cartridge 504 and the exhaust port 3. When cleaning the filter cartridge 504 is required, after shutting off the gas supply, the rotating rod 502 can be turned to rotate the filter cartridge 504. This allows the flexible rubber plate 510 on the inner wall of the delivery chamber 1 to scrape the surface of the filter cartridge 504. Furthermore, the perforated rotating plate 503 is activated when the filter cartridge 504 rotates. The components rotate synchronously, allowing the waste to be discharged into the collection chamber 512 when the perforated rotating plate 503 overlaps with the waste discharge port of the perforated fixed plate 513. When the rotating rod 502 is turned to rotate the filter cartridge 504, the sliding rod 507 can smoothly move on the inner wall of the guide groove 501, thereby allowing the round rubber ball 509 on the rubber rod 508 to periodically rotate and tap the tough rubber plate 510. Through vibration, the waste attached to the tough rubber plate 510 can be removed, ultimately ensuring that the filter cartridge 504 is clean while also achieving self-cleaning of the tough rubber plate 510.

[0028] When the rotating rod 502 is turned to rotate the filter cartridge 504, the circular rubber ball 509 on the rubber rod 508 can periodically rotate and strike the tough rubber plate 510. At the same time, the tough rubber plate 510 is also touched by the arc-shaped top block 601, which can further vibrate the tough rubber plate 510, so that the debris attached to the surface can fall off better. When the circular rubber ball 509 on the rubber rod 508 can periodically rotate and strike the tough rubber plate 510, the circular rubber ball 509 will be rubbed by the arc-shaped top block 602, which can further enhance the vibration effect and ultimately enhance the overall practicality.

[0029] When the final cleaning is completed, turn the rotating rod 502 again so that the hollow rotating plate 503 and the hollow fixing plate 513 no longer overlap, then the collection chamber 512 can be removed to collect and treat the pollutants.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
