Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a filter with good sealing effect. Background Art

[0002] A filter is a device used to remove particles and pollutants from the air to improve indoor air quality. They typically include filter media, such as fiber mesh or activated carbon, to capture dust, pollen, bacteria, viruses, and other airborne particles.

[0003] Publication No. CN218687503U discloses an air filter, which belongs to the field of laboratory air filtration technology, including an air filter body, the air filter body including a filter housing, the left side of the filter housing being connected and installed with two L-shaped air inlet pipes, a frame being arranged in the filter housing, and a filter plate 1, an activated carbon mesh plate, a dehumidification cotton plate and a filter plate 2 being installed in the frame from left to right in sequence; the air filter, by arranging a spring 1 and a push plate, utilizes the effect of one end of a fixing rod entering into a fixing groove to intercept and fix the frame, and fixes the frame in the filter housing, and combined with the reaction force of the spring 1 and the effect of the push plate, after the frame is released from fixation, the push plate will quickly push the frame upward and move it out of the filter housing, thereby realizing the rapid disassembly and installation of the frame, and then the filter plate 1, the activated carbon mesh plate, the dehumidification cotton plate and the filter plate 2 can be taken out, thereby improving the air filtering effect. Although this type of filtering device facilitates the disassembly of the filter plate, it is lacking in sealing performance. Since this type of filtering device does not have a structure for quickly replacing the sealing ring, the sealing ring will be corroded by the chemical substances in the gas when filtering the gas, and the corrosion of the sealing ring will lose the original sealing effect.

[0025] Embodiment 1

[0026] Please refer to Figures 1-6 , the present utility model provides a technical solution: a filter with good sealing effect, including a box body 1 and a connecting pipe 5. An air inlet pipe 2 and an exhaust pipe 3 are fixedly installed on the surface of the box body 1. The connecting pipe 5 is threadedly connected to the air inlet pipe 2. The threaded connection design of the connecting pipe 5 and the air inlet pipe 2 facilitates the installation of the connecting pipe 5 and also facilitates the replacement of the soft pad 8. A ring pad 4 is sleeved on the surface of the air inlet pipe 2. Clamping plates A6 and B7 are arranged on the surface of the connecting pipe 5. A soft pad 8 is fixedly installed on the surface of the clamping plate B7. An insertion bar A9 is inserted into the interior of the clamping plate A6. A rotating block 10 is rotatably connected to the surface of the insertion bar A9. The insertion bar A9 is threadedly connected to the rotating block 10. The threaded connection design between the insertion bar A9 and the rotating block 10 facilitates the fixing of the clamping plate and the soft pad 8 on the surface of the connecting pipe 5.

[0027] Please refer to Figures 1-6 , a fixing frame 11 is inserted into the interior of the box body 1. An insertion bar B12 is inserted into the surface of the fixing frame 11. The insertion bar B12 is threadedly connected to the box body 1. The threaded connection design of the insertion bar B12 and the box body 1 facilitates the installation of the fixing frame 11 on the box body 1 through the insertion bar B12. A sealing pad 13 is fixedly installed on the surface of the fixing frame 11. The sealing pad 13 is slidably connected to the box body 1. Soft pads 8 are fixedly installed on the surfaces of both the clamping plate A6 and the clamping plate B7. The materials of the soft pad 8, the ring pad 4, and the sealing pad 13 are all natural rubber. The design of the natural rubber material for the soft pad 8 and the ring pad 4 improves the sealing effect at the connection between the connecting pipe 5 and the air inlet pipe 2. The design of the natural rubber material for the sealing pad 13 improves the sealing effect at the connection between the fixing frame 11 and the box body 1. A filter plate A14, a filter plate B15, and a filter plate C16 are arranged inside the fixing frame 11. A blower 17 is arranged inside the box body 1.

[0028] Embodiment 2

[0029] Please refer to Figures 1-6The surface of the filter plate A14 is fixedly installed with a fixing plate 18. The design of the fixing plate 18 and the block 22 makes it easy to disassemble and replace the filter plate A14. A slide groove 19 is opened on the surface of the fixing plate 18. The interior of the fixing plate 18 is slidably connected with a slide rod 20. The surface of the slide rod 20 is sleeved with a spring 21. One end of the spring 21 is connected to the surface of the block 22, and the other end is connected to the inner surface of the fixing plate 18. The design of the spring 21 drives the block 22 to be stuck in the fixing frame 11. The surface of the slide rod 20 is fixedly installed with a block 22. The surface of the block 22 is fixedly installed with a shift block 23. The block 22 is slidably connected to the fixing frame 11, and the shift block 23 is slidably connected to the slide groove 19. The sliding design of the block 22 and the fixing frame 11 makes it easy to disassemble and assemble the filter plate A14 through the fixing plate 18 and the block 22, thereby facilitating the cleaning or replacement of the filter plate A14.

[0030] Working principle: when the ring gasket 4 and the soft pad 8 need to be replaced, only the insert A9 needs to be rotated, and the insert A9 can be taken out after it is rotated out of the rotating block 10. After taking out the insert A9, the splint A6 and the splint B7 can be removed from the surface of the connecting pipe 5. At this time, the connecting pipe 5 is rotated again, and the ring gasket 4 can be removed from the intake pipe 2 after the connecting pipe 5 is rotated out of the intake pipe 2. Then the new ring gasket 4 can be sleeved on the surface of the intake pipe 2, and then the connecting pipe 5 is installed with the intake pipe 2 through threads. After fixing the intake pipe 2, the splint A6 and the splint B7 with the new soft pad 8 are sleeved on the surface of the connecting pipe 5, and then the insert A9 and the rotating block 10 are installed through threads to complete the replacement of the soft pad 8 and the ring gasket 4. The splint A6, the splint B7, the soft pad 8, the ring gasket 4, the insert A9, the rotating block 10 and the connecting The tube 5 facilitates the replacement of the soft pad 8 and the ring gasket 4, thereby avoiding the leakage of gas from the joint of the intake pipe 2 due to the corrosion of the ring gasket 4, thereby improving the sealing effect of the filtering device. When the filter plate A14 needs to be cleaned, it is only necessary to push the shift block 23, and the shift block 23 will drive the block 22 to move. After the block 22 slides out of the fixed plate 18, the filter plate A14 can be pulled out from the fixed frame 11 through the fixed plate 18. At this time, the filter plate A14 can be cleaned or replaced. The fixed plate 18, the slide groove 19, the slide rod 20, the spring 21, the block 22 and the shift block 23 facilitate the disassembly and assembly of the filter plate A14, thereby facilitating the maintenance personnel to clean, maintain or replace the filter plate A14, avoiding the need to replace the filter plate A14 together with the national structure.
