Description

Technical Field

[0001] This utility model relates to the field of gas pressure regulation technology, specifically to a gas pressure regulation and high-efficiency filtration synergistic device that resists impurity interference. Background Technology

[0002] In modern energy supply systems, natural gas, as an efficient and clean energy source, is widely used in various fields such as industrial production, commercial operations, and daily life. During transportation and storage, various impurities, such as solid particles or liquids and some harmful gas components, inevitably get mixed in. The presence of these impurities can have a serious negative impact on gas pressure regulating equipment. Traditional pressure regulating devices are only equipped with simple filter structures with low filtration accuracy, making it difficult to effectively remove fine impurities in the natural gas. This causes the pressure regulating equipment to continue operating under abnormal conditions, which not only affects the pressure regulating effect but also accelerates the damage to the equipment.

[0003] Therefore, we propose a gas pressure regulating and high-efficiency filtration synergistic device that resists impurity interference to solve the above problems. Utility Model Content

[0024] This utility model discloses a gas pressure regulating and high-efficiency filtration synergistic device that resists impurity interference.

[0025] Example 1

[0026] This utility model provides, for example Figure 1-3 The gas pressure regulating and high-efficiency filtration combined device for resisting impurity interference is shown. It includes a pressure regulator 1 and a gas supply pipe 2 located at the lower end of the pressure regulator 1. The port of the gas supply pipe 2 is connected to a filter assembly. The filter assembly includes a filter tube 3 and a filter screen 4 located inside the filter tube 3. The filter screen 4 is inclined. A top cover 5 is fixedly provided on the top of the filter screen 4. A sludge outlet pipe 6 is connected to the bottom of the filter tube 3. A discharge valve 7 is fixedly provided on the wall of the sludge outlet pipe 6.

[0027] A miniature air pump 8 is fixedly installed at the lower back side of the top cover 5. The air outlet of the miniature air pump 8 is connected to an air blowing pipe 9. An air inlet filter 20 is fixedly installed at the air inlet of the miniature air pump 8. The opening of the air blowing pipe 9 is inserted into the top cover 5 and connected to an air guide pipe 10. The air blowing pipe 9 is a corrugated flexible hose, and the air guide pipe 10 is a rigid plastic tube. The opening of the air guide pipe 10 extends into the filter tube 3 and is connected to an air nozzle 11. The tube wall of the filter tube 3 has a through hole that matches the air guide pipe 10. A sealing rubber sleeve 19 is fixedly fitted on the upper end of the air guide pipe 10. The bottom of the sealing rubber sleeve 19 is fixedly connected to the tube wall of the filter tube 3 and fitted outside the through hole.

[0028] Example 2

[0029] Example 2, based on Example 1, in order to ensure the self-cleaning effect of filter 4, such as... Figure 1-2As shown, the top cover 5 is equipped with a swing cleaning mechanism for driving the air duct 10 to swing. The swing cleaning mechanism includes a drive shaft 12, which is rotatably located on the back side of the top cover 5. A motor 13 is fixedly installed on the back side of the top cover 5. The output shaft of the motor 13 is fixedly connected to the drive shaft 12. A sector gear 14 is fixedly sleeved on the shaft wall of the drive shaft 12. Two transmission racks 15 are fitted on the sector gear 14. A connecting frame 16 is fixedly installed between the two transmission racks 15. The connecting frame 16 is a U-shaped connecting frame. A square rod 17 slides through the inside of the transmission rack 15. The square rod 17 is fixedly installed inside the top cover 5. A fixing frame 18 is fixedly installed at the bottom of the transmission rack 15. The lower end of the fixing frame 18 is fixedly sleeved with the air duct 10.

[0030] Working principle: The gas first enters the filter tube 3 and is filtered by the filter screen 4. The clean gas enters the pressure regulator 1 through the gas transmission pipe 2 for pressure regulation. During the filtration process, impurities are intercepted by the filter screen 4. Because the filter screen 4 is set at an angle, the impurities are gathered at the bottom of the filter tube 3 by gravity and can be discharged by opening the discharge valve 7 on the impurity discharge pipe 6.

[0031] As filter screen 4 is used for a longer period and impurities accumulate on its surface, the micro air pump 8 is activated. Outside air, filtered by the intake filter 20, enters the micro air pump 8. Compressed air is sequentially ejected from the nozzle 11 through the air blowing pipe 9 and the air guide pipe 10, backflushing filter screen 4. Simultaneously, the motor 13 drives the drive shaft 12 to rotate, causing the sector gear 14 to rotate. The sector gear 14 alternately meshes with two transmission racks 15, causing the transmission racks 15 to slide left and right along the square rod 17 (the connecting frame 16 ensures the synchronous movement of the two transmission racks 15). The transmission racks 15, through the fixing frame 18, cause the air guide pipe 10 to swing left and right, and the nozzle 11 swings accordingly, expanding the backflushing range. The air blowing pipe 9 is a corrugated flexible hose to accommodate the swinging of the air guide pipe 10. The sealing rubber sleeve 19 seals the through holes in the filter tube 3 wall to prevent gas leakage. Through the above process, filtration and pressure regulation are coordinated, and the filter screen 4 is self-cleaned.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, 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.
