Description

Technical Field

[0001] This utility model belongs to the field of gas odorization technology, and specifically relates to a gas odorization tank with uniform mixing. Background Technology

[0002] A gas odorizing tank is a device in a gas transmission and distribution system used to add an odorant (odorant) to natural gas or liquefied petroleum gas to mix the gas with the odorant. Its core function is to artificially impart a distinct odor to the gas, helping users to detect gas leaks in a timely manner by smelling the obvious odor, and to take timely rescue measures to ensure gas safety.

[0003] A natural gas odorization device disclosed in Chinese Patent Publication No. CN215489124U includes a gas pipeline, an odorization tank, and a leak-proof pipe. The gas pipeline has an inlet and an outlet interface on its outer wall, with the inlet interface communicating with the gas pipeline. A suction pump is also installed on the outer wall of the gas pipeline. The leak-proof pipe surrounds the gas pipeline, with the suction pump installed on one side of it. One end of the leak-proof pipe is connected to the outlet interface, and the other end is connected to the gas pipeline. The odorization tank is installed on one side of the gas pipeline, and a first connecting pipe and a second connecting pipe are connected between the odorization tank and the gas pipeline. A shut-off valve is installed on the first connecting pipe, and a regulating valve and a shut-off valve are installed on the second connecting pipe. This device solves the problem of leakage of liquid odorant during addition.

[0004] However, when the aforementioned device odorizes the gas, it directly adds the odorant into the gas pipeline. Because the gas flows continuously within the pipeline, the odorant can only come into contact with one side of the gas flow, while the other side cannot effectively contact it due to its fluid dynamics characteristics, thus creating a mixing blind zone. This phenomenon results in a small contact area between the odorant and the gas when the odorant is added, causing the odorant and gas to not fully mix. This leads to an excessively low odorant concentration in some areas of the gas pipeline. If the odorant concentration in the pipeline is lower than the national standard, a leak may not be detected in time, easily leading to safety problems such as gas poisoning and gas explosion. Utility Model Content

[0005] To address the problem that odorants are difficult to fully mix with gas, this invention proposes a gas odor-adding canister for uniform mixing, thereby overcoming 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 is a gas odorizing tank for uniform mixing, including a mixing tank body, a gas pipe fixedly connected to the outer surface of the mixing tank body, a one-way valve fixedly installed at one end of the gas pipe, a mixing mechanism inside the mixing tank body, a transmission mechanism at the transmission end of the mixing mechanism, an odorizing mechanism at one end of the mixing tank body, a conveying end of the odorizing mechanism connected to the mixing mechanism, a discharge mechanism at the bottom of the mixing tank body, and a secondary mixing mechanism inside the discharge mechanism.

[0008] The transmission mechanism is used to drive the mixing mechanism to rotate. The mixing mechanism is used to mix and stir the gas and odorant delivered to the mixing tank body. The odorizing mechanism is used to deliver the odorant into the mixing tank body. The discharge mechanism is used to discharge the mixed odorant and gas. The secondary mixing mechanism is used to mix the discharged odorant and gas a second time.

[0009] Furthermore, a support frame is fixedly connected to the bottom of the mixing tank body.

[0010] Furthermore, the mixing mechanism includes a rotating roller, which is rotatably connected inside the mixing tank body. Multiple mixing rods are fixedly connected to the surface of the rotating roller, and multiple spray holes are opened on the surface of the multiple mixing rods. The rotating roller and the multiple mixing rods are hollow inside.

[0011] Furthermore, the transmission mechanism includes a fixed plate, which is fixedly connected to the upper surface of the mixing tank body. A motor is fixedly connected to the surface of the fixed plate, and a synchronous pulley is fixedly connected to the output shaft of the motor. A synchronous belt is engaged on the surface of the synchronous pulley, and a synchronous pulley is engaged on the inner wall of one end of the synchronous belt. The inner wall of the synchronous pulley is fixedly connected to one end of the surface of the rotating roller.

[0012] Furthermore, the odorizing mechanism includes a stabilizing plate, which is fixedly connected to the upper surface of the mixing tank body. A connecting pipe is fixedly connected to the inner wall of the stabilizing plate. One end of the connecting pipe is rotatably connected to the inner wall of one end of the rotating roller. A one-way valve is fixedly connected to the other end of the connecting pipe. An odorizing pipe is fixedly connected to one end of the one-way valve.

[0013] Furthermore, the discharge mechanism includes a discharge valve, which is fixedly connected to the bottom of the mixing tank body, and a discharge pipe is fixedly connected to one end of the discharge valve.

[0014] Furthermore, the secondary mixing mechanism includes a second motor, which is fixedly connected to the bottom of the support frame. The output shaft of the second motor is fixedly connected to a rotating rod, which is rotatably connected to one end of the discharge pipe. Multiple fan blades are fixedly connected to the surface of the rotating rod.

[0015] This utility model has the following beneficial effects: The output end of the gas output device is connected to one end of a one-way valve, with the one-way valve pointing from the output end of the gas output device into the gas pipe. The gas is then transported into the mixing tank body through the gas pipe. Odorizer is transported into the mixing mechanism through an odorizing mechanism, and then into the mixing tank body through the mixing mechanism. A transmission mechanism drives the mixing mechanism to rotate within the mixing tank body. As the mixing mechanism transports the odorizer into the mixing tank body, the rotation of the mixing mechanism mixes the odorizer and the gas, ensuring full contact and more uniform mixing. After mixing, the mixed gas is discharged through a discharge mechanism. During the discharge process, a secondary mixing mechanism further mixes the mixed gas to ensure uniform mixing of the odorizer and the gas.

[0016] This invention delivers gas into the mixing tank body. As the rotating roller rotates, the odorant is discharged through multiple nozzles on the surface of multiple mixing rods, coming into contact with the gas inside the mixing tank body. The rotating roller then rotates on the inner wall of the mixing tank body, driving multiple mixing rods to rotate inside the mixing tank body, mixing and stirring the gas and odorant, ensuring full contact between the odorant and the gas, making the mixing more uniform, and ensuring that the concentration of odorant in the gas meets national standards.

[0017] When discharging the mixed gas, the present invention uses a rotating rod to drive multiple fan blades to rotate inside the discharge pipe, thereby performing secondary mixing on the mixed gas being discharged to ensure uniform mixing of the gas and odorant and improve safety.

[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

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.

[0030] 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.

[0031] Please see Figures 1-6As shown, this utility model is a gas odorizing tank for uniform mixing, including a mixing tank body 1, a gas pipe 3 fixedly connected to the outer surface of the mixing tank body 1, a one-way valve 2 fixedly installed at one end of the gas pipe 3, a mixing mechanism 5 is provided inside the mixing tank body 1, a transmission mechanism 6 is provided at the transmission end of the mixing mechanism 5, an odorizing mechanism 7 is provided at one end of the mixing tank body 1, the conveying end of the odorizing mechanism 7 is connected to the mixing mechanism 5, a discharge mechanism 8 is provided at the bottom of the mixing tank body 1, and a secondary mixing mechanism 9 is provided inside the discharge mechanism 8.

[0032] The transmission mechanism 6 is used to drive the mixing mechanism 5 to rotate. The mixing mechanism 5 is used to mix and stir the gas and odorant delivered to the mixing tank body 1. The odorizing mechanism 7 is used to deliver the odorant to the mixing tank body 1. The discharge mechanism 8 is used to discharge the mixed odorant and gas. The secondary mixing mechanism 9 is used to mix the discharged odorant and gas a second time.

[0033] Connect the output end of the gas output device to one end of the one-way valve 2. The direction of the one-way valve 2 is from the output end of the gas output device to the gas pipe 3. The gas is delivered to the mixing tank body 1 through the gas pipe 3. The odorant is delivered to the interior of the mixing mechanism 5 through the odorizing mechanism 7. The mixing mechanism 5 is then delivered to the mixing tank body 1. The transmission mechanism 6 drives the mixing mechanism 5 to rotate inside the mixing tank body 1. When the mixing mechanism 5 delivers the odorant to the mixing tank body 1, the rotation of the mixing mechanism 5 mixes the odorant and the gas in the mixing tank body 1, ensuring full contact between the odorant and the gas and making the mixture more uniform. After mixing, the mixed gas is discharged through the discharge mechanism 8. During the discharge process, the mixed gas is mixed a second time through the secondary mixing mechanism 9 to ensure uniform mixing of the odorant and the gas.

[0034] The gas is delivered into the mixing tank body 1, and then the transmission mechanism 6 drives the mixing mechanism 5 to rotate so that the odorant is evenly sprinkled into the gas. At the same time, the mixing mechanism 5 can stir the gas to ensure that the odorant and the gas are in full contact and that the odorant and the gas are mixed more evenly. After mixing, the gas is discharged through the discharge mechanism 8. The gas is then mixed again through the secondary mixing mechanism 9 to ensure that the odorant and the gas are mixed evenly.

[0035] In one embodiment, for the mixing tank body 1, a support frame 4 is fixedly connected to the bottom of the mixing tank body 1.

[0036] The mixing tank body 1 is supported and stabilized by the support frame 4.

[0037] In one embodiment, the mixing mechanism 5 includes a rotating roller 501, which is rotatably connected inside the mixing tank body 1. Multiple mixing rods 502 are fixedly connected to the surface of the rotating roller 501. Multiple spray holes 503 are opened on the surface of the multiple mixing rods 502. The rotating roller 501 and the multiple mixing rods 502 are hollow inside.

[0038] The odorant reaches the inner wall of multiple mixing rods 502 through one end of the rotating roller 501. Both the rotating roller 501 and the inner wall of the multiple mixing rods 502 are hollow to facilitate the flow of the odorant. At the same time, the odorant is delivered to the inner wall of the mixing tank body 1 through multiple spray holes 503 opened on the surface of the multiple mixing rods 502. The rotation of the rotating roller 501 causes the rotating roller 501 to rotate on the inner wall of the mixing tank body 1. The rotating roller 501 drives the multiple mixing rods 502 to rotate on the inner wall of the mixing tank body 1, thus mixing and stirring the gas and the odorant.

[0039] In one embodiment, the transmission mechanism 6 includes a fixed plate 601, which is fixedly connected to the upper surface of the mixing tank body 1. A motor 602 is fixedly connected to the surface of the fixed plate 601. A synchronous pulley 603 is fixedly connected to the output shaft of the motor 602. A synchronous belt 604 is engaged with the surface of the synchronous pulley 603. A synchronous pulley 605 is engaged with the inner wall of one end of the synchronous belt 604. The inner wall of the synchronous pulley 605 is fixedly connected to one end of the surface of the rotating roller 501.

[0040] The fixing plate 601 fixes the motor 602. The motor 602 drives the synchronous pulley 603 to rotate, which in turn drives the synchronous pulley 605 through the synchronous belt 604. The synchronous pulley 605 then drives the rotating roller 501 to rotate on the inner wall of the mixing tank body 1, providing power for the rotation of the rotating roller 501.

[0041] In one embodiment, the odorizing mechanism 7 includes a stabilizing plate 701, which is fixedly connected to the upper surface of the mixing tank body 1. A connecting pipe 702 is fixedly connected to the inner wall of the stabilizing plate 701. One end of the connecting pipe 702 is rotatably connected to the inner wall of one end of the rotating roller 501. A one-way valve 703 is fixedly connected to the other end of the connecting pipe 702. An odorizing pipe 704 is fixedly connected to one end of the one-way valve 703.

[0042] One end of the odorizing pipe 704 is connected to the output end of the odorizing agent output device. The odorizing agent is delivered to the one-way valve 703 through the odorizing pipe 704. The direction of the one-way valve 703 is from the odorizing pipe 704 to the connecting pipe 702. The odorizing agent is delivered to the inner wall of the rotating roller 501 through the connecting pipe 702. When the rotating roller 501 rotates, it will rotate along the surface of one end of the connecting pipe 702. At the same time, the connection between the connecting pipe 702 and the rotating roller 501 is sealed to prevent the odorizing agent from leaking.

[0043] In one embodiment, the discharge mechanism 8 includes a discharge valve 801, which is fixedly connected to the bottom of the mixing tank body 1, and a discharge pipe 802 is fixedly connected to one end of the discharge valve 801.

[0044] After the gas and odorant are mixed in the mixing tank body 1, the discharge valve 801 is opened, so that the mixed gas is discharged through the discharge valve 801 and into the discharge pipe 802, and the mixed gas is discharged through the discharge pipe 802.

[0045] In one embodiment, the secondary mixing mechanism 9 includes a second motor 901, which is fixedly connected to the bottom of the support frame 4. The output shaft of the second motor 901 is fixedly connected to a rotating rod 902, which is rotatably connected to one end of the discharge pipe 802. Multiple fan blades 903 are fixedly connected to the surface of the rotating rod 902.

[0046] When the mixed gas is discharged, start motor 2 901, which drives the rotating rod 902 to rotate inside the discharge pipe 802. The rotating rod 902 drives multiple fan blades 903 to rotate inside the discharge pipe 802, thus performing secondary mixing on the mixed gas being discharged, to ensure uniform mixing of gas and odorant and improve safety.

[0047] Through the above technical solution, 1. Gas is delivered into the mixing tank body 1. While the rotating roller 501 rotates, the odorant is discharged through multiple nozzles 503 opened on the surface of multiple mixing rods 502, which come into contact with the gas in the mixing tank body 1. Then, the rotating roller 501 rotates on the inner wall of the mixing tank body 1, and the rotating roller 501 drives multiple mixing rods 502 to rotate inside the mixing tank body 1, mixing and stirring the gas and odorant, so that the odorant and gas are in full contact, the odorant and gas are mixed more evenly, and the concentration of odorant in the gas meets the national standard.

[0048] 2. When discharging the mixed gas, the rotating rod 902 drives multiple fan blades 903 to rotate inside the discharge pipe 802, which performs secondary mixing on the mixed gas being discharged, so as to ensure that the gas and odorant are mixed evenly and improve the safety effect.
