Description

Technical Field

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

[0002] Waste gas treatment devices mainly utilize different technologies to recover and reduce harmful components in exhaust gases, thereby achieving the goals of protecting the environment and purifying the air.

[0003] However, existing gas recovery and processing devices have the following drawbacks:

[0004] (1) Existing gas recovery and treatment devices have weak filtration functions. When in use, some gases carry small particulate impurities. Long-term use can easily cause the internal components of the device to become clogged, which can easily lead to a reduction in gas filtration quality.

[0005] (2) Existing gas recovery and treatment devices have weak cleaning functions. When in use, the filter components are generally fixed inside the device. When the filter components need to be removed for cleaning or replacement, the entire device needs to be disassembled in order to remove the filter components. After cleaning or replacement, they need to be reassembled, which can easily increase the cleaning cost of the entire device. Utility Model Content

[0006] The purpose of this invention is to provide a gas recovery and treatment device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A gas recovery and treatment device includes a housing, a connecting pipe fixedly disposed on one side of the housing, and a filter assembly fixedly disposed at one end of the connecting pipe. The filter assembly includes a fixed cylinder, a filter element, and an air inlet pipe. The fixed cylinder is threadedly sleeved at one end of the connecting pipe. The filter element is movably disposed inside the fixed cylinder. The width of the filter element is slightly larger than the width inside the fixed cylinder. The air inlet pipe is threadedly connected to one end of the fixed cylinder.

[0009] A fixed frame is movably arranged inside the housing. A sealing sleeve is fitted on the surface of the fixed frame. Several air holes are opened at the bottom of the fixed frame. Several activated carbon particles are filled inside the fixed frame. Handles are fixedly installed on both sides of the top of the fixed frame. An observation window is fixedly installed on the front of the housing.

[0010] Preferably, a top cover is movably provided at the top of the housing, a first sealing ring is fixedly provided at the top of the housing, a second sealing ring is fixedly provided at the bottom of the top cover, and a first positioning hole is provided on both sides of the top of the housing.

[0011] Preferably, a second positioning hole is provided on both sides of the top of the top cover, and a screw is movably disposed inside the second positioning hole.

[0012] Preferably, a rotating block is fixedly provided at the top end of the screw, and a fixing sleeve is threaded through the second positioning hole at the bottom end of the screw.

[0013] Preferably, an exhaust pipe is fixedly installed in the middle of the top of the top cover, and pull rods are fixedly installed on both the front and rear sides of the top of the top cover.

[0014] Preferably, a positioning ring is fixedly disposed inside the housing, and the top end of the positioning ring is movably connected to the bottom of the fixed frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This gas recovery and treatment device, through the arrangement of a fixed cylinder, filter element, and air inlet pipe, compresses the filter element and places it inside the fixed sleeve during use, so that the filter element fits tightly against the inner surface of the fixed sleeve. One end of the fixed sleeve is threaded to one end of the connecting pipe, and one end of the air inlet pipe is threaded to the other end of the fixed sleeve. Harmful gas is delivered into the air inlet pipe, and the gas passes through the filter element, which filters out small particulate impurities carried inside the gas. This achieves the effect of preventing harmful gas from carrying small particulate impurities into the housing and improving the overall gas filtration quality of the device.

[0017] This gas recovery and treatment device, through the arrangement of a sealing sleeve, activated carbon particles, and a light-wiping window, involves filling the inside of a fixed frame with activated carbon and then placing it inside the housing. Because the sealing sleeve fits tightly against the inner surface of the housing, gas entering the bottom of the housing can only pass through the vents into the fixed frame. The activated carbon particles inside the fixed frame adsorb harmful gases from the gas. When the surface of the activated carbon particles darkens through the observation window, the gas delivery is stopped, and the handle is pulled to remove the fixed frame from the housing, thus facilitating the replacement of the fully adsorbed activated carbon particles.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figures 1-4 As shown, the present invention provides a technical solution: a gas recovery and treatment device, including a housing 1, a connecting pipe 2 fixedly disposed on one side of the housing 1, a filter assembly fixedly disposed at one end of the connecting pipe 2, the filter assembly including a fixed cylinder 3, a filter element 4 and an air inlet pipe 5, a fixed cylinder 3 threadedly disposed at one end of the connecting pipe 2, a filter element 4 movably disposed inside the fixed cylinder 3, the width of the filter element 4 being slightly larger than the internal width of the fixed cylinder 3, and an air inlet pipe 5 threadedly connected to one end of the fixed cylinder 3;

[0025] In this embodiment, by setting up the fixed cylinder 3, filter element 4 and air inlet pipe 5, the filter element 4 is compressed and placed inside the fixed sleeve 19 during use, so that the filter element 4 is tightly attached to the inner surface of the fixed sleeve 19. One end of the fixed sleeve 19 is threaded to one end of the connecting pipe 2, and one end of the air inlet pipe 5 is threaded to the other end of the fixed sleeve 19. Harmful gas is delivered to the air inlet pipe 5. The gas passes through the filter element 4, and the filter element 4 filters out the small particulate impurities carried inside the gas, thereby achieving the effect of preventing harmful gas from carrying small particulate impurities into the housing 1 and improving the overall gas filtration quality of the device.

[0026] like Figure 2 and Figure 3 As shown, a fixed frame 6 is movably arranged inside the shell 1. A sealing sleeve 7 is fitted on the surface of the fixed frame 6. Several air holes 8 are opened at the bottom of the fixed frame 6. Several activated carbon particles 9 are filled inside the fixed frame 6. Handles 10 are fixedly arranged on both sides of the top of the fixed frame 6. An observation window 11 is fixedly arranged on the front of the shell 1.

[0027] In this embodiment, by setting up the sealing sleeve 7, activated carbon particles 9 and the light-wiping window, when in use, the inside of the fixing frame 6 is filled with a certain amount of activated carbon, and then it is placed inside the housing 1. Since the sealing sleeve 7 is tightly attached to the inner surface of the housing 1, the gas entering the bottom of the housing 1 can only pass through the air hole 8 to enter the inside of the fixing frame 6. The activated carbon particles 9 inside the fixing frame 6 adsorb the harmful gases inside the gas. When the surface color of the activated carbon particles 9 is found to be darkened through the observation window 11, the gas delivery is stopped, and then the handle 10 is pulled to remove the fixing frame 6 from the inside of the housing 1, thereby achieving the effect of facilitating the replacement of the fully adsorbed activated carbon particles 9.

[0028] like Figure 1 and Figure 3 As shown, a top cover 12 is movably provided at the top of the housing 1, a first sealing ring 13 is fixedly provided at the top of the housing 1, a second sealing ring 14 is fixedly provided at the bottom of the top cover 12, a first positioning hole 15 is provided on both sides of the top of the housing 1, a second positioning hole 16 is provided on both sides of the top of the top of the top cover 12, a screw 17 is movably provided inside the second positioning hole 16, a rotating block 18 is fixedly provided at the top of the screw 17, and a fixing sleeve 19 is threaded through the second positioning hole 16 at the bottom of the screw 17.

[0029] In this embodiment, by setting the top cover 12, the first sealing ring 13 and the second sealing ring 14, when in use, the rotating block 18 is rotated, and the bolt at the bottom of the rotating block 18 is threaded through the first positioning hole 15 and the second positioning hole 16 and the fixing sleeve 19, so that the first sealing layer and the second sealing layer are tightly attached, and the filtered gas is discharged from the exhaust pipe 20 in the middle of the top of the top cover 12, thereby achieving the effect of enhancing the airtightness of the overall device.

[0030] like Figure 1 and Figure 4 As shown, an exhaust pipe 20 is fixedly installed in the middle of the top of the top cover 12, and a pull rod 21 is fixedly installed on both the front and rear sides of the top of the top of the top cover 12. A positioning ring 22 is fixedly installed inside the housing 1, and the top of the positioning ring 22 is movably connected to the bottom of the fixed frame 6.

[0031] In this embodiment, by setting the pull rod 21, when it is necessary to remove the fixing frame 6 inside the housing 1, the fixing sleeve 19 is fixed, the rotating block 18 is rotated in the opposite direction, so that the screw 17 is pulled out of the first positioning hole 15 and the second positioning hole 16, and then the pull rod 21 is pulled, thereby achieving the effect of removing the top cover 12 from the top of the housing 1. By setting the positioning ring 22, the position of the fixing frame 6 inside the housing 1 can be restricted during use, thereby achieving the effect of preventing the bottom of the fixing frame 6 from being tightly attached to the bottom of the housing 1.

[0032] Working Principle: With the fixed cylinder 3, filter element 4, and inlet pipe 5, the filter element 4 is compressed and placed inside the fixed sleeve 19 during use, ensuring a tight fit between the filter element 4 and the inner surface of the fixed sleeve 19. One end of the fixed sleeve 19 is threaded to one end of the connecting pipe 2, and one end of the inlet pipe 5 is threaded to the other end of the fixed sleeve 19, supplying harmful gas to the inlet pipe 5. The gas passes through the filter element 4, which filters out small particulate impurities carried within the gas, thus preventing harmful gas from carrying small particulate impurities into the housing 1 and improving the overall gas filtration quality. Simultaneously, with the sealing sleeve 7, activated carbon particles 9, and a light-wiping window, the fixed frame 6 is filled with activated carbon during use and then placed inside the housing 1. Because the sealing sleeve 7 is tightly fitted to the inner surface of the housing 1, gas entering the bottom of the housing 1 can only pass through the air hole 8 into the fixed frame 6. The activated carbon particles 9 inside the fixed frame 6 adsorb the harmful gas inside the gas. When the surface of the activated carbon particles 9 darkens through the observation window 11, the gas flow is stopped. The conveying mechanism involves pulling handle 10 to remove the fixing frame 6 from the housing 1, facilitating the replacement of the fully adsorbed activated carbon particles 9. Through the top cover 12, the first sealing ring 13, and the second sealing ring 14, the rotating block 18 is rotated during use. The bolt at the bottom of the rotating block 18 passes through the first positioning hole 15 and the second positioning hole 16, threadedly connecting to the fixing sleeve 19. This ensures a tight seal between the first and second sealing layers, allowing the filtered gas to exit through the exhaust pipe 20 at the top center of the top cover 12, thus achieving… To enhance the overall airtightness of the device, the pull rod 21 is used so that when the fixed frame 6 inside the housing 1 needs to be removed, the fixed sleeve 19 is fixed, the rotating block 18 is rotated in the opposite direction, and the screw 17 is pulled out of the first positioning hole 15 and the second positioning hole 16. Then the pull rod 21 is pulled, thereby achieving the effect of removing the top cover 12 from the top of the housing 1. The positioning ring 22 is used to restrict the position of the fixed frame 6 inside the housing 1, thereby preventing the bottom of the fixed frame 6 from being tightly attached to the bottom of the housing 1.
