Description

Technical Field

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

[0002] Gas filtration devices are used to remove impurities, harmful substances, or odors from gases. They are widely used in industrial waste gas treatment, indoor air purification, laboratory ventilation systems, and medical protection. Their core principle is to effectively remove pollutants such as particulate matter, volatile organic compounds, and toxic gases from gases through physical adsorption, chemical reactions, or mechanical interception, thereby purifying the gases. Among many filter materials, activated carbon is widely used as an adsorbent due to its well-developed pore structure and huge specific surface area, especially showing excellent performance in removing odors and organic pollutants.

[0003] However, existing gas filtration devices using activated carbon as the filter medium require regular replacement to maintain filtration efficiency because the activated carbon gradually becomes saturated and loses its adsorption capacity after long-term use. However, most devices are not designed for easy replacement, often requiring the entire device to be shut down, the outer casing opened, or even partially disassembled to remove the old activated carbon and replace it with new filler. This process is not only cumbersome and time-consuming, but may also lead to a decrease in sealing performance due to frequent disassembly and assembly, affecting filtration efficiency and even causing secondary pollution. Therefore, we propose a gas filtration device. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figures 1 to 7 This utility model provides a technical solution: a gas filtration device, comprising: a connecting shell 1;

[0028] It also includes: a connecting shaft 2, which is located in the inner cavity of the connecting shell 1 and is rotatably connected to the connecting shell 1. A placement box 21 is fixedly connected to the outer surface of the connecting shaft 2. A mesh plate 24 is rotatably connected to the lower part of the connecting shaft 2 and is fixedly connected to the inner cavity of the connecting shell 1. An air outlet chamber 22 is fixedly connected to the lower end of the mesh plate 24. The mesh plate 24 has a discharge trough 241 and a discharge bin 23 is fixedly connected to the lower end of the mesh plate 24. The inner cavity of the discharge trough 241 and the inner cavity of the discharge bin 23 are connected. The air outlet chamber 22 is fixedly connected to the inner wall of the connecting shell 1, the material outlet chamber 23 is fixedly connected to the inner wall of the connecting shell 1, the upper end of the connecting shell 1 is fixedly connected to the first connecting plate 3, the upper side of the first connecting plate 3 is fixedly connected to the air inlet pipe 7, and the inner cavity of the air inlet pipe 7 communicates with the inner cavity of the connecting shell 1, the lower end of the connecting shell 1 is fixedly connected to the second connecting plate 61, the side of the second connecting plate 61 near the air inlet pipe 7 is fixedly connected to the air outlet pipe 8, and the inner cavity of the air outlet pipe 8 communicates with the inner cavity of the connecting shell 1;

[0029] Drive component 4 is located in the middle of the first connecting plate 3 and is used to drive the connecting shaft 2 to rotate.

[0030] Limiting component 5 is disposed on the side of the first connecting plate 3 near the driving component 4, and is used to limit the driving component 4.

[0031] When it is necessary to replace saturated activated carbon, simply drive the connecting shaft 2 to rotate via the drive component 4. This will align the chamber containing the old activated carbon in the placement box 21 with the discharge trough 241, allowing it to automatically fall into the discharge bin 23 below. Simultaneously, another chamber containing fresh activated carbon will rotate to the gas passage position between the inlet pipe 7 and the outlet pipe 8, continuing to perform the filtration function. This effectively avoids the problems of decreased sealing, cumbersome operation, time and labor consumption, and potential secondary pollution caused by frequent opening and disassembly of traditional devices. Since multiple chambers can be used alternately, users can complete the preparation for activated carbon replacement or even the partial replacement process while the equipment is operating normally, reducing downtime.

[0032] A feeding chamber 31 is fixedly connected to one side of the first connecting plate 3. A sealing plate 32 is fixedly connected to the side of the first connecting plate 3 near the connecting shaft 2. A feeding groove 33 is opened on the side of the sealing plate 32 near the feeding chamber 31, and the inner cavity of the feeding groove 33 communicates with the inner cavity of the feeding chamber 31. The driving component 4 includes a connecting bolt 41 that is rotatably connected to the first connecting plate 3. A first handle 43 is fixedly connected to the side of the connecting bolt 41 away from the first connecting plate 3. The connecting shaft 2 is fixedly connected to the side of the connecting bolt 41 away from the first handle 43.

[0033] The limiting component 5 includes a support block 51 fixedly connected to the first connecting plate 3. A first threaded bolt 53 is threadedly connected to the side of the support block 51 away from the first connecting plate 3. A limiting block 54 is rotatably connected to the side of the first threaded bolt 53 near the connecting bolt 41. The limiting block 54 is arc-shaped and has several limiting grooves 55 on the side of the limiting block 54 near the connecting bolt 41. Several limiting teeth 42 are fixedly connected in an annular array on the outer surface of the connecting bolt 41 near the limiting block 54. A second handle 52 is fixedly connected to the side of the first threaded bolt 53 away from the limiting block 54. Both the second handle 52 and the first handle 43 have several anti-slip patterns in an annular array. Both the second handle 52 and the first handle 43 are made of rubber material.

[0034] When it is necessary to replace the saturated activated carbon, the user rotates the first handle 43, which in turn rotates the connecting bolt 41. Since the connecting bolt 41 is fixedly connected to the connecting shaft 2, the rotation of the connecting bolt 41 will drive the connecting shaft 2 to rotate, and the rotation of the connecting shaft 2 will drive the placement box 21 to rotate. The placement box 21 containing the old activated carbon will then rotate to be directly above the discharge trough 241. The old activated carbon filling the placement box 21 will then automatically fall into the discharge chamber 23 below. Since the inner cavity of the discharge chamber 23 is connected to the inner cavity of the receiving box 6, the old activated carbon falling into the inner cavity of the discharge chamber 23 will fall into the inner cavity of the receiving box 6. At the same time, another chamber containing fresh activated carbon will rotate to the gas passage position between the inlet pipe 7 and the outlet pipe 8 to continue to perform the filtration function.

[0035] Then, the user rotates the second handle 52, which in turn drives the first threaded bolt 53 to rotate. This pushes the limiting block 54 to slide toward one side of the connecting bolt 41. With the cooperation of several limiting grooves 55 and several limiting teeth 42, the position of the connecting bolt 41 can be limited. Since both the first handle 43 and the second handle 52 are made of rubber material, and both the outer surfaces of the first handle 43 and the second handle 52 are provided with several anti-slip textures, it is convenient for the user to rotate the second handle 52 and the first handle 43.

[0036] A feeding chamber 31 is fixedly connected to one side of the first connecting plate 3, and a sealing plate 32 is fixedly connected to the side of the first connecting plate 3 near the connecting shaft 2. A feeding groove 33 is opened on the side of the sealing plate 32 near the feeding chamber 31, and the inner cavity of the feeding groove 33 communicates with the inner cavity of the feeding chamber 31. Thus, when it is necessary to replenish the activated carbon in the multiple chambers of the placement box 21, activated carbon can be poured into the inner cavity of the feeding chamber 31, and then the activated carbon can be replenished into the multiple chambers of the placement box 21 through the inner cavity of the feeding groove 33.

[0037] Example 2

[0038] A second threaded bolt 62 is fixedly connected to the middle of the second connecting plate 61. A receiving box 6 is slidably connected to the second threaded bolt 62. A nut 63 is threadedly connected to the side of the second threaded bolt 62 away from the second connecting plate 61. The inner cavity of the receiving box 6 communicates with the inner cavity of the discharge bin 23.

[0039] When it is necessary to process the activated carbon that has fallen into the inner cavity of the receiving box 6, the position restriction of the receiving box 6 can be released by rotating the operating nut 63, and then the receiving box 6 can be removed from the second threaded bolt 62, and the saturated activated carbon collected in the inner cavity of the receiving box 6 can be processed.
