Description

Technical Field

[0001] This utility model relates to the field of gas filter technology, and in particular to a gas filter with a quick filter element replacement method. Background Technology

[0002] Gas filters can effectively remove dust, particulate matter, liquids and other contaminants from gas, preventing these impurities from entering gas equipment and avoiding blockage or damage to key components such as pressure reducing valves, pressure relief valves and gas water heaters, thus extending the service life of the equipment.

[0003] Gas filters primarily filter impurities through their internal filter elements. After prolonged use, the saturated filter elements need to be replaced. The gas filter has a base plate at the bottom, with multiple positioning screw holes on its surface. A fixing plate is installed at the bottom of the base plate using bolts, thus sealing the filter element inside the gas filter. Replacing the filter element requires removing the bolts on the fixing plate one by one. Since there are multiple bolts, disassembly is very troublesome, resulting in low filter element replacement efficiency. Utility Model Content

When the filter element body 16 inside the gas filter body 1 needs to be replaced, there is no need to remove multiple bolts. Disassembly is quick and convenient. After replacing the filter element, the lower fixing plate 10 is placed at the lower end of the chassis 2, and the anti-slip handle 22 is rotated in the opposite direction to complete the installation. The limiting assembly ensures the tightness of the fixation and the sealing by fixing the lower fixing plate 10 at multiple points.

[0026] Please see Figure 4 - Figure 7In this embodiment, the limiting component includes a connecting post 7, which is fixedly connected to the lower end of the toothed ring 6. A limiting plate 8 is fixedly connected to the lower end of the connecting post 7, and a fastening block 9 is fixedly connected to the upper end of the limiting plate 8. The surface of the limiting plate 8 is arc-shaped and slidably connected to the surface of the lower fixing plate 10. L-shaped grooves 11 are evenly distributed on the surface of the lower fixing plate 10. A fastening block 12 is fixedly connected to the end of the L-shaped groove 11, and the fastening block 12 contacts the fastening block 9. The fastening block 9 is used to press the fastening block 12. A notch is provided at the upper end of the L-shaped groove 11, allowing the limiting plate 8 to pass through. A locking block 13 is evenly distributed on the surface of the lower fixing plate 10, and a locking block 4 is evenly distributed on the surface of the chassis 2. The locking block 4 is used to block the locking block 13. When replacing the filter element body 16 inside the gas filter body 1, rotate the anti-slip handle 22 to rotate the component. The gear ring 6 rotates, and the fastening block 19 disengages from the fastening block 2 12 on the surface of the lower fixing plate 10. The lower fixing plate 10, no longer pressed and fixed by the fastening block 19, can be removed. There is no need to remove multiple bolts, making disassembly quick and convenient. After replacing the filter element, re-fix the lower fixing plate 10 at the lower end of the chassis 2. Rotate the anti-slip handle 22 in the opposite direction, and the gear ring 6, which is engaged with the gear 23, rotates simultaneously. In this way, the fastening block 19 re-engages with the fastening block 2 12. The fastening block 19 fixes the lower fixing plate 10 by pressing the fastening block 2 12. There are multiple sets of fastening blocks 19. By fixing the lower fixing plate 10 at multiple points, the tightness of the fixation and the sealing performance are ensured.

One end of the worm 21 passes through the protective shell 24. The anti-slip handle 22 is rotated in the opposite direction. The anti-slip handle 22 drives the worm 21 to rotate at the bearing seat 20. The worm wheel 19, which is meshed with the worm 21, rotates at the bearing seat 18 at the same time. The gear 23, which is fixedly connected to the lower end of the worm wheel 19, rotates at the same time. The gear ring 6, which is meshed with the gear 23, rotates at the same time at the inner bearing 5.

[0028] When it is necessary to replace the filter element body 16 inside the gas filter body 1, turn the anti-slip handle 22, the rotating component runs, the toothed ring 6 rotates, and the connecting post 7 fixedly connected to the lower end of the toothed ring 6 rotates at the same time. The fastening block 1 9 on the surface of the limiting plate 8 disengages from the fastening block 2 12 on the surface of the lower fixing plate 10. The lower fixing plate 10, which is not pressed and fixed by the fastening block 1 9, can be disassembled without removing multiple bolts, making disassembly quick and convenient.

[0029] After replacing the filter element, the lower fixing plate 10 is re-fixed at the lower end of the chassis 2. The limiting plate 8 is passed through the upper notch of the L-shaped groove 11.
