Description

Technical Field

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

[0002] In the field of gas transmission and application technology, odorization is a crucial step in ensuring the safety of gas use. Gas itself is mostly colorless and odorless, making leaks difficult to detect. Adding odorants allows leaks to be detected promptly, effectively preventing accidents.

[0003] Chinese patent discloses a gas pipe odorizing device (publication number CN220749846U). In this patent, the problem of "the common connection between the gas pipe odorizing device and the gas pipe is a straight pipe connection or a bend pipe connection, but both of these odorizing methods are straight discharge, so in actual use, the high flow rate of natural gas will lead to uneven mixing of odorant and gas, making it difficult to fully exert the effect of odorant" is addressed by setting up a gas mixing component. When the gas comes into contact with the gas inlet pipe and the deformable hose, the gas inlet pipe and the deformable hose will cause the gas to generate a vortex. By utilizing the vortex and the cooperation of the inner wall of the sphere, the mixing effect of odorant and gas can be improved, so that the odorant and gas can be mixed evenly, and thus the effect of odorant can be fully exerted.

[0004] However, in actual use, although the deformation hose can be adjusted and its adjustment direction can be changed by pressure, it is difficult to match the pressure of the odorant inlet pipe with the pressure of the gas transmission. During the gas transmission process, the gas pressure will fluctuate frequently due to factors such as changes in gas source and pipeline resistance. However, the pressure of the odorant inlet pipe is difficult to adjust in real time and accurately to follow the changes in gas pressure. This leads to the inability of the odorant and gas to mix effectively when the pressure is not well matched, resulting in unstable gas quality after odorization and affecting the safe use of gas. Therefore, it is impossible to effectively mix the odorant and gas. To address this, we propose a gas mixing and odorizing device. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a gas mixing and odorizing device to solve the problems of gas mixing and odorizing devices.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a gas mixing and odorizing device, including an odorizing tank, an odorizing pipe fixedly installed on the output end of the odorizing tank, a gas mixing box provided at the end of the odorizing pipe away from the odorizing tank, the interior of the gas mixing box being a spherical cavity, and the odorizing pipe penetrating through the corresponding wall of the gas mixing box and communicating with the interior of the gas mixing box, an inlet pipe and an outlet pipe fixedly installed on both sides of the gas mixing box respectively, the inlet pipe and the outlet pipe both penetrating through the corresponding wall of the gas mixing box and communicating with the interior of the gas mixing box, a drive motor provided at the position corresponding to the odorizing pipe on the side of the gas mixing box away from the odorizing pipe, and a diffusion mixing component provided inside the gas mixing box, the diffusion mixing component being movably installed on the odorizing pipe, and the diffusion mixing component being connected to the output end of the drive motor.

[0007] Preferably, the diffusion mixing assembly includes a diffusion block and a diffusion groove.

The side of the diffusion block near the odorizing pipe is hollow. The diffusion groove is annularly spaced on the side wall of the diffusion block at the end away from the odorizing pipe. The diffusion groove obliquely penetrates the side wall of the diffusion block and communicates with the interior of the diffusion block. The end of the diffusion block away from the odorizing pipe is connected to the output end of the drive motor.

[0008] Preferably, the diffusion mixing assembly further includes a rotating slot and a rotating plate. The rotating slot is located on the inner sidewall of the odorizing pipe near one end of the diffusion block. The rotating slot is an "I"-shaped annular groove. The rotating plate is located inside the rotating slot. The size of the rotating plate matches the size of the inner side of the rotating slot. The end of the rotating plate near the diffusion block is fixedly connected to the diffusion block.

[0009] Preferably, the diffusion mixing assembly further includes a flow guide block, which is disposed on the inner side of the diffusion block at the end away from the odorizing pipe.

[0010] Preferably, the flow guide block includes a base plate, a guide plate, and an impact block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In this utility model, the diffusion mixing component is driven by a drive motor to rotate inside the gas mixing box. At the same time, the guide block inside the diffusion block works in conjunction with the diffusion groove. Under the centrifugal force generated by the rotation, the odorant can be effectively transported into the gas mixing box.

[0015] 2. In this utility model, the odorant is evenly distributed by the impact block, and the guide plate and the guide groove on its side wall guide the odorant in a spiral direction to disperse and transport it.

[0023] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0024] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0025] Figures 1-4 As shown, a gas mixing and odorizing device includes an odorizing tank 1, which is a publicly available technology and will not be described in detail here. An odorizing pipe 2 is fixedly installed on the output end of the odorizing tank 1. A gas mixing box 3 is provided at the end of the odorizing pipe 2 away from the odorizing tank 1. The interior of the gas mixing box 3 is a spherical cavity, and the odorizing pipe 2 penetrates through the corresponding wall of the gas mixing box 3 and communicates with the interior of the gas mixing box 3. An inlet pipe 4 and an outlet pipe 5 are fixedly installed on both sides of the gas mixing box 3, respectively. Both the inlet pipe 4 and the outlet pipe 5 penetrate through the corresponding wall of the gas mixing box 3 and communicate with the interior of the gas mixing box 3. A drive motor 6 is provided on the side of the gas mixing box 3 away from the odorizing pipe 2 at the position corresponding to the odorizing pipe 2. A diffusion mixing component is provided inside the gas mixing box 3. The diffusion mixing component is movably installed on the odorizing pipe 2 and is connected to the output end of the drive motor 6.

[0026] In this embodiment, the drive motor 6 starts and drives the diffusion mixing component to rotate on the odorizing pipe 2. The centrifugal force generated by the rotation diffuses the odorizing material that is being transported into the gas mixing box 3 through the odorizing pipe 2, and effectively mixes it with the gas under the pressure of the gas transmitted through the inlet pipe 4.

[0027] Furthermore, the diffusion mixing assembly includes a diffusion block 7, a diffusion groove 8, a rotating slot 9, a rotating plate 10, and a guide block. The diffusion block 7 is disposed inside the gas mixing box 3, and the position of the diffusion block 7 corresponds to the position of the odorizing pipe 2. The side of the diffusion block 7 closest to the odorizing pipe 2 is hollow. The diffusion groove 8 is annularly spaced on the side wall of the diffusion block 7 at the end away from the odorizing pipe 2. The diffusion groove 8 obliquely penetrates the side wall of the diffusion block 7 and communicates with the interior of the diffusion block 7. The end of the diffusion block 7 away from the odorizing pipe 2 is connected to the output end of the drive motor 6.

[0028] In this embodiment, the spaced diffusion channels 8 allow the odorant to be diffused and transported into the interior of the gas mixing box 3 and mixed with the fuel gas transported by the intake pipe 4 under the rotation of the diffusion block 7.

[0029] Furthermore, the rotating slot 9 is located on the inner side wall of the odorizing pipe 2 near the end of the diffuser block 7. The rotating slot 9 is an "I"-shaped annular groove. The rotating plate 10 is located inside the rotating slot 9. The size of the rotating plate 10 is adapted to the size of the inner side of the rotating slot 9. The end of the rotating plate 10 near the diffuser block 7 is fixedly connected to the diffuser block 7.

[0030] In this embodiment, the rotating plate 10 can rotate on the rotating slot 9.

[0031] Furthermore, the guide block is positioned inside the diffuser block 7 at the end furthest from the odor-adding pipe 2.

[0032] In this embodiment, the odorizing material transported inside the odorizing pipe 2 can be guided and transported to the diffusion tank 8 by the guide block, thereby facilitating the mixing of the odorizing material through the diffusion.

[0033] Furthermore, the flow guide block includes a substrate 11, a guide plate 12, and an intercepting block 14. The substrate 11 is fixedly installed on the inner side of the diffuser block 7 at the end away from the odorizing pipe 2. The intercepting block 14 is a hemispherical block and is located in the middle of the inner side of the diffuser block 7. The arc surface of the intercepting block 14 corresponds to the odorizing pipe 2. The guide plate 12 is a frustum-shaped tube and is located between the substrate 11 and the intercepting block 14. The guide plate 12 gradually narrows from the end near the substrate 11 to the end near the intercepting block 14. The two ends of the guide plate 12 are respectively connected to the corresponding wall surfaces of the substrate 11 and the intercepting block 14.

[0034] In this embodiment, the odorant transmitted by the odorant pipe 2 can be evenly distributed and conducted through the arc-shaped impact block 14, thereby making the odorant transmitted through the diffusion groove 8 more uniform and easier to mix evenly with the gas.

[0035] Furthermore, guide grooves 13 are provided at intervals and at an angle on the side wall of the guide plate 12.

[0036] In this embodiment, the rotation of the diffuser block 7 and the guide groove 13 on the side wall of the guide plate 12 enable the odorant to be effectively dispersed and transported in a spiral direction, and can be better mixed with the gas under the cooperation of the gas transmission pressure.

[0037] Furthermore, the guide plate 12 is made of a material capable of elastic memory deformation. The material of the guide plate 12 includes, but is not limited to, rubber, plastic, etc. An adjustment spring 15 is provided on the inner side of the guide plate 12, and the two ends of the adjustment spring 15 are respectively connected to the impact block 14 and the diffuser block 7.

[0038] In this embodiment, the spring 15 can be adjusted to allow elastic adjustment between the impact block 14 and the base plate 11. When the pressure of the odorant transmitted through the odorant pipe 2 increases, the impact block 14 is squeezed by the pressure. The spring 15 is adjusted accordingly, thereby causing the guide plate 12 to tilt accordingly. This allows the tilt angle of the guide plate 12 to be adjusted accordingly. This reduces the guiding angle of the guide plate 12 when the transmission pressure is high, allowing the odorant transmitted through the guide plate 12 to be transmitted closer to the inner side wall of the gas mixing box 3. Conversely, when the pressure is low, the odorant transmitted through the guide plate 12 can be transmitted closer to the inner center of the gas mixing box 3. This allows for transmission adjustment according to the pressure, making it easier to mix with the gas during transmission.

[0039] Working principle and usage process of this utility model:

[0040] In use, the inlet pipe 4 and outlet pipe 5 are installed on the designated pipeline through flanges. When odorization is required, the odorizing material inside the odorization tank 1 is transferred to the gas mixing box 3 through the odorization pipe 2. At the same time, the gas is transferred to the gas mixing box 3 through the inlet pipe 4. The diffusion mixing component is rotated and adjusted by the drive motor 6, so that the odorization can be transferred into the gas mixing box 3 in a spiral diffusion according to the transmission pressure, thereby fully mixing with the gas.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
