Description

Technical Field

[0001] This utility model belongs to the field of gas pipe technology, and specifically relates to an odorizing device for gas pipes. Background Technology

[0002] Natural gas is widely developed and used in both industrial production and residential gas supply systems. However, due to its physical properties, natural gas is colorless and odorless or has a slight odor, which poses a potential hazard to its safe use. Gas leaks are not easily detected in time, so it is necessary to use odorizing equipment to ensure that gas leaks can be detected by people or instruments in a timely manner, allowing for prompt measures to be taken to prevent accidents.

[0003] Chinese patent CN220249689U discloses a gas pipe odorization device, which relates to the field of gas pipes. The gas pipe odorization device includes an odor storage tank, an air inlet pipe is provided through the top of the odor storage tank, and an air outlet pipe is fixedly connected to the bottom of the odor storage tank. A filter chamber is provided outside the end of the air outlet pipe, and the air outlet pipe and the filter chamber are fixedly connected. A fixing ring is fixedly installed on the outer surface of the filter chamber near the top position. A fan is provided above the fixing ring, and limit blocks are fixedly installed on both sides of the fan.

[0004] Some gas pipe odorizing devices lack the function of filtering leaked gas. Since odor leaks may occur when these devices are connected to gas pipelines, traditional odorizing devices cannot filter or adsorb the leaked gas, allowing the odor to disperse directly. The aforementioned document describes blowing the leaking odor downwards to adsorb and filter it before discharging. However, this method lacks a sealing component between the filter plate and the filter chamber, which can easily lead to a poor seal, allowing some odor to escape unfiltered through the gaps. Utility Model Content

[0005] To address the problem of uneven distribution of odor in pipelines, this utility model proposes an odor-adding device for gas pipelines to overcome the aforementioned technical problems existing in related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an odor-adding device for gas pipelines, comprising an odor storage tank, a sealed container fixedly connected to the outer surface of the odor storage tank, a connecting assembly disposed inside the sealed container, a gas pipeline fixedly connected to the outer surface of the connecting assembly, a filter assembly and a limiting assembly disposed inside the sealed container, the connecting assembly being used to connect the odor storage tank and the gas pipeline, the filter assembly being used to filter odorous gas, the limiting assembly being used to limit and fix the filter assembly, and a detector being fixedly connected inside the sealed container.

[0008] Furthermore, the connecting assembly includes a connecting pipe, one end of which is fixedly connected to the odor storage tank, and the other end of which is fixedly connected to a sleeve. Both ends of the sleeve are fixedly connected to a gas pipe. A horizontal plate is fixedly connected inside the sleeve, and a fan blade is rotatably connected to the outer surface of the horizontal plate.

[0009] Furthermore, the filter assembly includes a rotating plate rotatably connected to the inside of the sealed container, a filter seat is threadedly connected to the outer surface of the rotating plate, and a filter layer is filled inside the filter seat.

[0010] Furthermore, the limiting component includes a fixing plate, which is fixedly connected to the inside of the sealed container. A pneumatic push rod is fixedly connected to the bottom of the fixing plate, and a connecting plate is fixedly connected to the movable end of the pneumatic push rod. Bolts are fixedly installed on the outer surface of the connecting plate, and a sealing ring is fixedly installed on the connecting plate by the bolts.

[0011] Furthermore, an exhaust pipe is fixedly connected to the outer surface of the sealed container, and a pressure relief valve is fixedly installed at the end of the exhaust pipe.

[0012] Furthermore, a cap is fixedly connected to the top of the sealed container by bolts, and a handle is fixedly connected to the top of the cap.

[0013] Furthermore, a bracket is fixedly connected to the bottom of the odor storage tank, and the bracket is fixedly connected to the sealed tank by bolts.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model connects the sealed container and the filter assembly. When the filter surface of the filter assembly is facing upward, the gas leaking into the sealed container between the connecting component and the gas pipe passes through the filter assembly and is discharged. The filter assembly can adsorb and filter this gas to prevent adverse reactions from maintenance personnel. After maintenance is completed, the filter assembly is rotated in the sealed container so that the filter surface of the filter assembly faces downward. At this time, the personnel can replace the filter assembly at the bottom of the sealed container.

[0016] 2. This utility model connects the rotating plate and the sealing ring. The movable end of the pneumatic push rod pushes the sealing ring downward. Multiple sets of pneumatic push rods and the sealing ring simultaneously apply pressure to the rotating plate, so that the rotating plate is subjected to uniform force and can be limited, avoiding unnecessary rotation of the rotating plate. The sealing ring enters between the rotating plate and the sealed container, strengthening the sealing between the rotating plate and the sealed container and preventing leakage from this point.

[0017] 3. This utility model connects the fixing plate and the fan blade. The fan blade is located inside the sleeve. When the gas in the gas pipe passes through the fan blade and enters the sleeve, the gas will drive the fan blade to rotate. The airflow brought by the rotation of the fan blade can disturb the gas and odor, making the mixture of gas and odor more uniform.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0030] Please see Figures 1-6 As shown, this utility model is a gas pipe odorization device, including an odor storage tank 1, a sealed tank 2 fixedly connected to the outer surface of the odor storage tank 1, a connecting component 3 disposed inside the sealed tank 2, a gas pipe 4 fixedly connected to the outer surface of the connecting component 3, a filter component 5 and a limiting component 6 disposed inside the sealed tank 2, the connecting component 3 is used to connect the odor storage tank 1 and the gas pipe 4, the filter component 5 is used to filter odor, the limiting component 6 is used to limit and fix the filter component 5, and a detector 7 is fixedly connected inside the sealed tank 2.

[0031] After the odor storage tank 1 is connected to the gas pipe 4 inside the sealed tank 2 via the connecting component 3, the odor in the odor storage tank 1 enters the gas pipe 4 after passing through the connecting component 3 and mixes with the gas. The mixed gas is then transported normally. If a leak occurs at the connection between the connecting component 3 and the gas pipe 4, the detector 7 inside the sealed tank 2 will detect the leak and issue an alarm to the staff. The leaked gas will pass through the filter component 5 and be discharged to prevent excessive pressure inside the sealed tank 2. The filter component 5 can absorb and filter the odor, preventing adverse reactions when staff are near it. After maintenance is completed, the limiting component 6 moves upward and separates from the filter component 5, releasing the limiting fixation on the filter component 5. This allows the filter component 5 to rotate so that its filter surface faces down, making it easier for staff to replace the filter component 5. After replacement, the filter component 5 is reversed, and the limiting component 6 is then pressed against the filter component 5 to prevent unnecessary rotation of the filter component 5 and to improve the sealing between the filter component 5 and the sealed tank 2.

[0032] This invention connects the sealed container 2 to the filter assembly 5. When the filter surface of the filter assembly 5 is facing upward, the gas leaking into the sealed container 2 between the connecting component 3 and the gas pipe 4 passes through the filter assembly 5 and is discharged. The filter assembly 5 can adsorb and filter this gas to prevent adverse reactions from maintenance personnel. After maintenance is completed, the filter assembly 5 is pushed to rotate inside the sealed container 2 so that the filter surface of the filter assembly 5 faces downward. At this time, the personnel can replace the filter assembly 5 at the bottom of the sealed container 2.

[0033] In one embodiment, the connecting component 3 includes a connecting pipe 301, one end of which is fixedly connected to the odor storage tank 1, and the other end of which is fixedly connected to a sleeve 302. Both ends of the sleeve 302 are fixedly connected to the gas pipe 4. A horizontal plate 303 is fixedly connected inside the sleeve 302, and a fan blade 304 is rotatably connected to the outer surface of the horizontal plate 303.

[0034] The connecting pipe 301 is connected to the odor storage tank 1 via a flange. The odor in the odor storage tank 1 enters the sleeve 302 through the connecting pipe 301. The sleeve 302 is threadedly connected to the gas pipe 4, and the connecting pipe 301, sleeve 302 and gas pipe 4 are interconnected. When the gas in the gas pipe 4 passes through the fan blade 304, it will drive the fan blade 304 to rotate. The fan blade 304 blows the gas and stirs the odor from the sleeve 302 to the gas pipe 4, so that the odor and gas can be fully mixed and the uneven mixing can be avoided.

[0035] In one embodiment, the filter assembly 5 includes a rotating plate 501, which is rotatably connected to the inside of the sealed container 2. A filter seat 502 is threadedly connected to the outer surface of the rotating plate 501, and a filter layer 503 is filled inside the filter seat 502.

[0036] When a leak occurs between the sleeve 302 and the gas pipe 4, the leaked gas enters the sealed container 2, passes through the filter seat 502 on the rotating plate 501 below the sealed container 2, and the filter layer 503 in the filter seat 502 can adsorb and filter the odor, preventing workers from inhaling excessive odor and causing adverse reactions. After maintenance of the leak is completed, the rotating plate 501 is pushed to rotate, causing the rotating plate 501 to drive the filter seat 502 to rotate. When the filter seat 502 is facing down, the workers can remove the filter seat 502 on the rotating plate 501 and replace it.

[0037] In one embodiment, the limiting component 6 includes a fixing plate 601, which is fixedly connected to the inside of the sealed container 2. A pneumatic push rod 602 is fixedly connected to the bottom of the fixing plate 601, and a connecting plate 603 is fixedly connected to the movable end of the pneumatic push rod 602. A bolt 604 is fixedly installed on the outer surface of the connecting plate 603, and a sealing ring 605 is fixedly installed on the connecting plate 603 by the bolt 604.

[0038] Multiple sets of fixed plates 601 and pneumatic push rods 602 are symmetrically distributed inside the sealed tank 2. After the pneumatic push rod 602 is activated, it drives the connecting plate 603 and the sealing ring 605 to move upward, causing them to separate from the rotating plate 501. At this time, the rotating plate 501 can rotate. After the filter seat 502 on the rotating plate 501 is replaced, the pneumatic push rod 602 drives the sealing ring 605 to move downward, allowing it to enter the gap between the rotating plate 501 and the sealed tank 2. This enhances the sealing between the rotating plate 501 and the sealed tank 2, preventing leakage from this point.

[0039] In one embodiment, for the aforementioned sealed container 2, an exhaust pipe 8 is fixedly connected to the outer surface of the sealed container 2, and a pressure relief valve 9 is fixedly installed at the end of the exhaust pipe 8.

[0040] After being filtered by the filter seat 502 and the filter layer 503, the gas enters the exhaust pipe 8. When the pressure in the exhaust pipe 8 and the sealed tank 2 reaches a certain level, the pressure relief valve 9 on the exhaust pipe 8 opens to allow the gas to be discharged, thus preventing the pressure in the sealed tank 2 from becoming too high.

[0041] In one embodiment, for the aforementioned sealed container 2, the top of the sealed container 2 is fixedly connected to a cover 10 by bolts 604, and the top of the cover 10 is fixedly connected to a handle 11.

[0042] Removing bolt 604 will release the connection between the cover 10 and the sealed container 2. Pulling handle 11 will remove the cover 10 from the top of the sealed container 2, making it easier for staff to maintain the equipment located at the top of the sealed container 2.

[0043] In one embodiment, for the above-mentioned odor storage tank 1, a bracket 12 is fixedly connected to the bottom of the odor storage tank 1, and the bracket 12 is fixedly connected to the sealed tank 2 by bolts 604.

[0044] The bracket 12 is used to support the odor storage tank 1 and the sealed tank 2, so that there is a certain gap between the sealed tank 2 and the ground, and to provide rotation space for the rotating plate 501 inside the sealed tank 2.

[0045] In summary, using the above-mentioned technical solution of this utility model, the odor storage tank 1 is connected to the gas pipe 4 via the connecting pipe 301 and the sleeve 302. The odor in the odor storage tank 1 enters the gas pipe 4 after passing through the connecting pipe 301. When the normally flowing gas in the gas pipe 4 passes through the fan blade 304, it drives the fan blade 304 to rotate. The airflow generated by the rotation of the fan blade 304 can disrupt the gas and odor mixture, making the mixture more uniform. If a leak occurs between the sleeve 302 and the gas pipe 4, the leaked odor and gas enter the sealed tank 2. The detector 7 inside the sealed tank 2 detects the leak and issues an alarm. The sealed tank 2 also serves as a temporary gas storage unit, preventing further leakage of gas and odor, thus buying time for repairs. As the pressure inside the sealed tank 2 gradually increases, the odor inside the sealed tank 2... Gas is discharged from exhaust pipe 8 through pressure relief valve 9. During the discharge process, this gas passes through filter seat 502 and filter layer 503 inside sealed tank 2. Filter seat 502 and filter layer 503 filter and adsorb odor to prevent workers from inhaling too much odor and causing adverse reactions. After maintenance, pneumatic push rod 602 is activated. Pneumatic push rod 602 drives connecting plate 603 and sealing ring 605 to move upward, so that connecting plate 603 and sealing ring 605 are separated from rotating plate 501. At this time, rotating plate 501 can rotate. After filter seat 502 on rotating plate 501 is replaced, pneumatic push rod 602 drives sealing ring 605 to move downward, so that sealing ring 605 enters the gap between rotating plate 501 and sealed tank 2, which can enhance the sealing between rotating plate 501 and sealed tank 2.

[0046] Through the above technical solution, 1. By connecting the sealed tank 2 and the filter assembly 5, when the filter surface of the filter assembly 5 is facing upwards, the gas leaking into the sealed tank 2 between the connecting assembly 3 and the gas pipe 4 passes through the filter assembly 5 and is discharged. The filter assembly 5 can adsorb and filter this part of the gas, preventing adverse reactions from maintenance personnel. After maintenance is completed, pushing the filter assembly 5 to rotate inside the sealed tank 2 can make the filter surface of the filter assembly 5 face downwards, at which time the personnel can replace the filter assembly 5 at the bottom of the sealed tank 2; 2. Through the connection between the rotating plate 501 and the sealing ring 605, the movable end of the pneumatic push rod 602 pushes the sealing ring 605 downwards, and multiple sets of pneumatic... The push rod 602 and the sealing ring 605 simultaneously apply pressure to the rotating plate 501, making the rotating plate 501 evenly stressed and limiting its movement to prevent unnecessary rotation. The sealing ring 605 enters between the rotating plate 501 and the sealing tank 2, strengthening the seal between them and preventing leakage. 3. Through the connection of the fixing plate 303 and the fan blade 304, the fan blade 304 is located inside the sleeve 302. When the gas in the gas pipe 4 passes through the fan blade 304 and enters the sleeve 302, the gas will drive the fan blade 304 to rotate. The airflow generated by the rotation of the fan blade 304 can disturb the gas and odor, making the mixture of gas and odor more uniform.
