Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment filter element technology, and more specifically, to exhaust gas treatment filter element with a sealing structure. Background Technology

[0002] Exhaust gas treatment filter cartridges are core components of industrial purification equipment, used to filter dust, particulate matter, and some organic pollutants from exhaust gases. They are widely used in industries such as electronics, pharmaceuticals, and chemicals. Common types include plate and frame filters, pleated filters, and activated carbon cartridges, and materials include non-woven fabrics, glass fiber, and activated carbon. During use, various pollutants are blocked by the exhaust gas treatment filter cartridge, thus remaining on the cartridge. The accumulation of pollutants will affect the airflow efficiency and adsorption capacity of the filter cartridge. Therefore, exhaust gas treatment filter cartridges need to be replaced in a timely manner to ensure filtration effectiveness. When installing or removing exhaust gas treatment filter cartridges, they must be sealed to prevent cross-contamination between the filter cartridge and air pollutants.

[0003] Most existing exhaust gas treatment filter elements do not have a sealing structure. When the exhaust gas treatment filter element is installed or removed from the sealing structure, it is easily exposed to the environment or comes into contact with workers during the installation and removal process, which can easily lead to contact contamination, affect the working effect of the exhaust gas treatment filter element or pollute the environment.

[0004] In summary, to address the issue of exhaust gas treatment filter cartridges being easily exposed to the environment or coming into contact with workers during use, it is necessary to ensure that the exhaust gas treatment filter cartridges can be opened or closed after installation and before disassembly to improve the protective effect. Utility Model Content

[0005] The problem that this utility model provides for the exhaust gas treatment filter element with a sealed structure is that: when the existing exhaust gas treatment filter element is removed from the sealed structure or stored during installation and removal, it is easily exposed to the environment or comes into contact with workers, which can easily cause contact pollution, affecting the working effect of the exhaust gas treatment filter element or polluting the environment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste gas treatment filter element with a sealing structure, comprising a filter element body, mounting brackets on both sides of the filter element body, a rotating ring rotatably connected to the inner side of the mounting bracket, a positioning bracket on the rotating ring, a support ring on the outer side of the mounting bracket, a positioning ring on the support ring, a first baffle for forming a sealing structure rotatably connected to the inner side of the positioning ring, external blocks mounted on both sides of the first baffle, a connecting bracket on the outer side of the positioning bracket, and a second baffle for combined sealing between the two connecting brackets.

[0007] In a preferred embodiment, the mounting bracket has a sliding groove, and the outer side of the sliding groove has a mounting hole, which is rotatably connected to the first baffle and the outer block.

[0008] In a preferred embodiment, a connecting rod is fixedly connected to one side of the rotating ring, the connecting rod is slidably connected to the mounting bracket through a groove, an outer plate is installed on one side of the connecting rod, a positioning rod is fixedly connected to the inner side of the outer plate, and a mating block is fixedly connected to one side of the outer plate.

[0009] In a preferred embodiment, a fixing ring is provided on the outer side of the support ring, and a fixing rod is fixedly connected to the outer side of the fixing ring.

[0010] In a preferred embodiment, a rotating plate is rotatably connected to the outer side of the rotating ring, a limit groove is formed on the rotating plate, and a moving block is provided between the rotating plate and the fixed ring.

[0011] In a preferred embodiment, a fixing groove is provided on the movable block, the fixing groove and the fixing ring are slidably connected by a fixing rod, and a sliding rod is fixedly connected to one side of the movable block, the sliding rod and the rotating plate are slidably connected by a limiting groove.

[0012] In a preferred embodiment, an inner sealing tube is provided on the inner side of the filter element body, and a docking frame is fixedly connected to both sides of the inner sealing tube. The docking frame is slidably connected to the outer plate through a positioning rod. An outer rod is installed on the outer side of the docking frame, and a connecting block is installed on the outer side of the outer rod and the docking block.

[0013] The beneficial effects of this utility model are as follows: This utility model uses a mounting bracket to install multiple sets of first baffles and external blocks, thereby partially blocking the filter element body. A rotating ring, positioning bracket, and connecting bracket push the second baffle to move, so that the first and second baffles together block the filter element body. At the same time, the external block rotates the superimposed structure of the first and second baffles to ensure that the filter element body works normally or is sealed. The connecting bracket is used to connect the external plate to cooperate with the inner sealing tube to seal the inside of the filter element body.

[0014] This utility model facilitates the installation of the filter element body through the mounting bracket. By rotating the outer plate, the connecting rod drives the rotating ring to rotate. At the same time, the fixing ring is fixed to the external structure. The rotating plate and the limiting groove drive the sliding rod and the moving block to move. The moving block's movement path is restricted by the fixing rod and the fixing groove, thereby enabling the moving block to move in a directional manner. Attached Figure Description

The connecting bracket 22 is installed and pushed by rotating ring 5 and positioning bracket 6, thereby pushing the second baffle 23 to move through the connecting bracket 22, so that the first baffle 15 and the second baffle 23 together block the filter element body 1, thus completing the seal.

[0025] It is worth noting that the second baffle 23 is movable and fits against the first baffle 15, which facilitates the filtration work of the filter element body 1. At the same time, a pull spring is provided on the inner side of the connecting frame 22, and the stacked structure of the first baffle 15 and the second baffle 23 can be rotated through the outer connecting block 16 to improve the overall openness and ensure the normal operation of the filter element body 1. Meanwhile, flexible pads are provided on the contact surfaces of the first baffle 15 and the second baffle 23, which can effectively block dust and particulate matter when stacked and unfolded, ensuring the sealing effect on the outside.

[0026] Refer to the instruction manual appendix Figure 2 The mounting bracket 2 has a sliding groove 3, and the outer side of the sliding groove 3 has a mounting hole 4, which is rotatably connected to the first baffle 15 and the outer block 16.

[0027] It should be noted that the mounting bracket 2 facilitates the installation of the filter element body 1 and allows the rotating ring 5 to rotate and be limited.

[0028] Refer to the instruction manual appendix Figure 3 A connecting rod 7 is fixedly connected to one side of the rotating ring 5. The connecting rod 7 is slidably connected to the mounting bracket 2 through the sliding groove 3. An outer plate 8 is installed on one side of the connecting rod 7. A positioning rod 9 is fixedly connected to the inner side of the outer plate 8. A mating block 10 is fixedly connected to one side of the outer plate 8.

[0029] It should be noted that the outer plate 8 is installed through the connecting rod 7, and the outer plate 8 is rotated, thereby driving the rotating ring 5 to rotate through the connecting rod 7.

[0030] Refer to the instruction manual appendix Figure 4 A fixing ring 13 is provided on the outer side of the support ring 11, and a fixing rod 14 is fixedly connected to the outer side of the fixing ring 13.

[0031] It should be noted that the fixing ring 13 is fixed to the external structure, thereby facilitating the external positioning of the device through the fixing ring 13 and the fixing rod 14.

[0032] Refer to the instruction manual appendix Figure 5 A rotating plate 17 is rotatably connected to the outer side of the rotating ring 5. A limit groove 18 is provided on the rotating plate 17. A moving block 19 is provided between the rotating plate 17 and the fixed ring 13.

[0033] It should be noted that the outer sealing and fixing are achieved by moving block 19, thereby improving the overall sealing effect.

[0034] Refer to the instruction manual appendix Figure 5 The movable block 19 has a fixed groove 20, which is slidably connected to the fixed ring 13 via a fixed rod 14. A sliding rod 21 is fixedly connected to one side of the movable block 19, and the sliding rod 21 is slidably connected to the rotating plate 17 via a limiting groove 18.

[0035] It should be noted that the sliding rod 21 and the moving block 19 are moved by the rotating plate 17 and the limiting groove 18, and the moving path of the moving block 19 is restricted by the fixing rod 14 and the fixing groove 20, thereby enabling the moving block 19 to move in a directional manner.

[0036] Refer to the instruction manual appendix Figure 6 An inner sealing tube 24 is provided on the inner side of the filter element body 1. A docking frame 25 is fixedly connected to both sides of the inner sealing tube 24. The docking frame 25 is slidably connected to the outer plate 8 through a positioning rod 9. An outer connecting rod 26 is installed on the outer side of the docking frame 25. A connecting block 27 is installed on the outer side of the outer connecting rod 26 and the docking block 10.

[0037] It should be noted that the outer plate 8 is connected to the docking bracket 25, which works in conjunction with the inner sealing tube 24 to seal the inside of the filter element body 1, thereby improving the overall sealing effect.

[0038] It is worth noting that the connecting block 27 connects and fixes the outer rod 26 and the docking block 10, thereby fixing the inner sealing tube 24 and the outer plate 8, which facilitates the overall movement. At the same time, multiple sets of moving blocks 19 are provided, which can fully surround the positioning frame 6 and close the space between the rotating plate 17 and the fixing ring 13, improving the sealing effect, and can be unfolded and cleaned when needed.

[0039] Working principle: First, the filter element body 1 is conveniently installed through the mounting bracket 2, which also facilitates the rotation and limiting of the rotating ring 5. Next, the outer plate 8 is installed through the connecting rod 7, and the outer plate 8 is rotated, thereby driving the rotating ring 5 to rotate through the connecting rod 7. Then, the fixing ring 13 is fixed to the external structure, thereby facilitating the external positioning of the device through the fixing ring 13 and the fixing rod 14. Finally, the sliding rod 21 and the moving block 19 are moved through the rotating plate 17 and the limiting groove 18, and the moving path of the moving block 19 is limited by the fixing rod 14 and the fixing groove 20, thereby enabling the moving block 19 to move in a directional manner.

[0040] In use, firstly, multiple sets of first baffles 15 and external blocks 16 are installed through the mounting bracket 2 to partially block the outside of the filter element body 1. Next, the connecting bracket 22 is installed and pushed through the rotating ring 5 and the positioning bracket 6, thereby pushing the second baffle 23 to move, so that the first baffle 15 and the second baffle 23 jointly block the filter element body 1, completing the seal. Then, the overlapping structure of the first baffle 15 and the second baffle 23 is rotated through the external block 16 to increase the overall openness or close it, ensuring that the filter element body 1 works normally or is closed. Finally, the external plate 8 is connected through the docking bracket 25 to cooperate with the inner sealing tube 24 to initially seal the inside of the filter element body 1. During overall storage and retrieval, a sealing plug is set in the groove formed by the docking bracket 25 and the positioning rod 9 to further improve the sealing effect.
