Technical Field

[0001] The utility model relates to the technical field of flue gas collection, in particular to a vacuum flue gas collector. Background Technique

[0002] In industrial production and manufacturing, a large amount of flue gas is generated after the combustion of flammable substances. This kind of flue gas usually contains more harmful substances, seriously affecting the air quality and environment. Therefore, the flue gas must be treated to meet the national standard requirements before being discharged into the environment. In order to ensure that the discharged flue gas meets the requirements, it is necessary to detect it regularly.

[0003] When detecting gases, gas detection is a common type of environmental detection. For gas sampling, a flue gas collector is mostly used to collect flue gas.

[0004] At present, most of the flue gas collectors on the market use a vacuum pump or a fan to extract the flue gas into the collector. However, the existing flue gas sampler can only perform flue gas sampling at a certain point at a time. In this way, there will be a large error in the detection of flue gas, and it is not easy to comprehensively judge the quality of flue gas, affecting the detection effect. Moreover, the gases collected at different heights cannot be stored in separate chambers, resulting in the mixing of flue gas and affecting the subsequent detection effect. Content of the Utility Model

[0032] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a vacuum type flue gas collector, including a pushing frame 1, an installation box 2 is fixed on the top of the pushing frame 1, a concave frame 3 that can be lifted and slid is arranged inside the installation box 2, a mounting rack 4 is fixed on the top of the concave frame 3, a suction pipe 5 penetrates through the inside of the mounting rack 4, and a suction hood 6 is communicated with the end side of the suction pipe 5;

[0034] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, a fixed plate 31 is fixed inside the installation box 2. A connecting plate 32 is fixed to the end side of the fixed plate 31. A motor 33 is fixed to the bottom of the connecting plate 32. The output end of the motor 33 is fixedly connected to a transmission rod 34. A driving gear 35 is fixed to the top of the transmission rod 34. A driven gear 36 is meshed with the end side of the driving gear 35. Transmission gears 38 are meshed with both ends of the driven gear 36. A screw rod 39 is threadedly connected to the middle of the transmission gears 38. The screw rod 39 is fixedly connected to the concave frame 3.

[0035] In this embodiment, as Figure 1 、 Figure 2 and Figure 3 shown, a support shaft 37 is fixed to the top of the fixed plate 31. There are three support shafts 37. The driven gear 36 and the transmission gears 38 are rotatably sleeved on the support shafts 37 evenly.

[0036] In this embodiment, as Figure 1 、 Figure 2 and Figure 3 shown, a telescopic rod 310 is fixed to the bottom of the screw rod 39. The telescopic rod 310 is fixedly connected to the installation box 2.

[0037] In this embodiment, as Figure 1 、 Figure 2 and Figure 3 shown, a connecting flange 81 is fixedly sleeved on the top of the corrugated pipe 8. Screws 82 penetrate through the inner part of the circumference of the connecting flange 81. Nuts 83 are threadedly sleeved on the outside of the screws 82. Thread grooves 71 are formed on the surface of the flange pipe 7. The screws 82 are threadedly connected to the thread grooves 71. There are two flange pipes 7, corrugated pipes 8, and flue gas collection bins 11.

[0038] It should be noted that flange pipes 7 are installed at both the bottom and the end side of the suction pipe 5. Two air delivery pipes 9 are provided. Both of the two air delivery pipes 9 can be connected to the flange pipe 7. When connecting to the corrugated pipe 8 at the connection side end, the absorbed flue gas is sent into the upper flue gas collection bin 11. When connecting to the corrugated pipe 8 below, it is sent into the lower flue gas collection bin 11. And a detachable plug plate is clamped inside the flange pipe 7. When not in use, it is blocked by the plug plate to prevent the flue gas from flowing out and affecting the stability of collection. And the corrugated pipe 8 has elasticity and will not be restricted during connection.

[0039] In this embodiment, as Figure 1 、 Figure 2 and Figure 3 shown, an exhaust gas port is formed inside the exhaust gas pipe 12. A control valve is installed at the upper end of the exhaust gas pipe 12.

[0040] It should be noted that the discharge of flue gas is controlled by a control valve, which is not opened when not in use. It is only opened when it is necessary to sample the flue gas to control its discharge. And controlling the discharge of flue gas through a control valve belongs to the existing technology in this field, so it will not be elaborated in detail.

[0041] It should be noted that for the motor 33 and the vacuum pump 10, the specific model specifications need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated.

[0042] The usage method and advantages of the present utility model: When the vacuum type flue gas collector works, the working process is as follows:

[0043] As Figure 1 、 Figure 2 and Figure 3 shown, when collecting flue gas, first connect the flange pipe 7 with the upper gas transmission pipe 9, drive the corrugated pipe 8 to stretch by the connecting flange 81, so that the connecting flange 81 fits against the end side of the flange pipe 7. At the same time, the screw 82 on the connecting flange 81 passes through the screw groove 71 on the flange pipe 7, and then rotate the nut 83 along the screw 82 to make it fit against the end side of the flange pipe 7, thereby connecting the suction pipe 5 with the gas transmission pipe 9. Start the vacuum pump 10, so that the flue gas is sucked into the suction pipe 5 by the suction hood 6 and transported to the upper flue gas collection bin 11 through the gas transmission pipe 9 for collection;

[0044] When collecting flue gas at different heights, start the motor 33 to drive the transmission rod 34 to drive the driving gear 35 to rotate. The driving gear 35 rotates and meshes with the driven gear 36, so that the driven gear 36 rotates around the support shaft 37 under force and meshes with the transmission gears 38 on both sides. The transmission gears 38 rotate under force and are in threaded cooperation with the screw, so that the screw 39 slides upward under force and drives the concave frame 3 at the top to lift, so that the suction hood 6 can be adjusted up and down, so that flue gas at multiple heights can be collected, improving the flexibility of use, and can comprehensively judge different flue gases, improving the detection effect;

[0045] If the flue gas absorbed at different heights is stored in a single flue gas collection bin 11, it will cause mixing and affect the subsequent detection effect of the flue gas. When collecting flue gas at different heights, disassemble the upper connecting flange 81 from the flange pipe 7, insert a blocking plate into the nozzle of the flange pipe 7, and then connect the connecting flange 81 on the lower corrugated pipe 8 with the flange pipe 7 under the suction pipe 5. The flue gas will be sucked into the lower gas transmission pipe 9 through the suction hood 6 and sent into the lower flue gas collection bin 11, so that the gases collected at different heights can be stored in separate chambers, avoiding the mixing of flue gases from affecting the subsequent detection effect and improving the usability.

[0046] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model.
