Technical Field

[0001] The utility model relates to the technical field of industrial waste gas collection, in particular to an exhaust gas collection device with good sealing performance for industrial waste gas detection. Background Technique

[0002] Industrial waste gas refers to various polluted gases discharged into the air during industrial production activities by fuel combustion and production processes.

[0003] In order to monitor the discharged waste gas to ensure its compliance with national or local emission standards, it is necessary to collect industrial waste gas samples for analysis to understand its impact on the environment, and then facilitate the adoption of effective pollution control measures to reduce the emission of harmful substances.

[0004] The emission sources of industrial waste gas may be at different heights. For example, multiple exhaust pipes or chimneys in a factory may have different emission heights, but the existing collection devices can only be fixed at a certain height, easily missing the direct collection of some key emission points. Especially when the pollutants from high emission sources are diluted in the low-level air due to atmospheric diffusion, the monitoring results may not accurately reflect the actual emission situation. Content of the Utility Model

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0023] Combined with Figure 1 - Figure 2 , an exhaust gas collection device with good sealing performance for industrial exhaust gas detection, including a bottom plate 1, universal wheels 11 provided at the bottom end of the bottom plate 1, a collection box 2 provided at the top end of the bottom plate 1, and a box door 21 movably connected to one side of the collection box 2. Above the bottom plate 1, a collection assembly 4 for collecting industrial exhaust gas is provided, and a collection bottle 3 is provided on one side of the collection box 2.

[0024] The following further describes the present utility model in conjunction with the embodiments.

[0025] Embodiment 1:

[0026] Please refer to Figure 2 - Figure 5, the collection component 4 includes an air pump 41 fixedly installed at the bottom end of the inner wall of the collection box 2 and an installation box 42, an installation groove 421 opened on one side of the installation box 42, a motor 43 fixedly installed at the bottom end of the inner wall of the installation groove 421, a threaded rod 44 fixedly connected to the output end of the motor 43, a slider 45 threadedly connected to the outer surface of the threaded rod 44, a connecting plate 46 fixedly connected to one side of the slider 45, a delivery pipe 47 fixedly connected to the top end of the connecting plate 46, and a gas collection hood 48 fixedly connected to one end of the delivery pipe 47. The intake end of the air pump 41 is fixedly connected with a connecting hose 411, and the outlet end of the air pump 41 is fixedly connected with a delivery pipe 412. One end of the connecting hose 411 is fixedly connected to the delivery pipe 47. One end of the threaded rod 44 is rotatably connected to the top end of the inner wall of the installation groove 421. The connecting hose 411 penetrates through the connecting plate 46, and both the delivery pipe 412 and the delivery pipe 47 penetrate through the collection box 2. One end of the gas collection hood 48 is provided with a filtering component 7 for filtering waste gas. By driving the threaded rod 44 to rotate through the motor 43, the slider 45 is driven to move up and down. The up and down movement of the slider 45 drives the connecting plate 46 and the delivery pipe 47 to move up and down, thereby driving the gas collection hood 48 to move up and down, facilitating the adjustment of the height during waste gas collection to adapt to waste gas emission sources at different heights, improving the flexibility and application range of collection. Under the action of the air pump 41, the external waste gas sequentially enters the delivery pipe 412 through the gas collection hood 48, the delivery pipe 47, and the connecting hose 411, and finally is transmitted to the inside of the collection bottle 3 through the delivery pipe 412 to complete the collection.

[0027] The filtering component 7 includes a fixed pipe 71 fixedly connected to one end of the gas collection hood 48, a filtering pipe 73 movably connected inside the fixed pipe 71, a first filter plate 74 and a second filter plate 75 movably connected inside the filtering pipe 73 in sequence from inside to outside, and a threaded fixing rod 72 threadedly connected between the filtering pipe 73 and the fixed pipe 71. One end of the threaded fixing rod 72 is fixedly connected with a crank 721. The filtering level of the first filter plate 74 is greater than that of the second filter plate 75. The first filter plate 74 and the second filter plate 75 are used to filter solid particles in the waste gas to prevent the solid particles from polluting and blocking the fixed pipe 71. By rotating the crank 721 to drive the threaded fixing rod 72 to rotate, the threaded fixing rod 72 is separated from the filtering pipe 73 and the fixed pipe 71, facilitating the extraction of the filtering pipe 73 from the inside of the fixed pipe 71 to replace or clean the first filter plate 74 and the second filter plate 75.

[0028] A sealing rubber ring 711 is fixedly connected to the connection part between the fixed pipe 71 and the filtering pipe 73. The sealing rubber ring 711 is convenient for filling the tiny gap between the fixed pipe 71 and the filtering pipe 73 to prevent the unfiltered waste gas from directly entering the delivery pipe 47 by bypassing the filtering pipe 73.

[0029] One side of the collection box 2 close to the collection bottle 3 is provided with a limiting groove 22. A first forward thread groove 221 is formed in the inner wall of the limiting groove 22. A reverse thread groove 31 is formed at the mouth of the collection bottle 3. The limiting groove 22 corresponds to the mouth of the collection bottle 3, and the first forward thread groove 221 corresponds to the reverse thread groove 31. Rotating the collection bottle 3 makes the first forward thread groove 221 and the reverse thread groove 31 engage with each other, facilitating the fixation of the collection bottle 3 to the collection box 2. At this time, the air supply pipe 412 penetrates through the collection box 2 and is connected to the inside of the mouth of the collection bottle 3, facilitating the conveyance of waste gas. Rotating the collection bottle 3 in the reverse direction facilitates the disassembly of the collection bottle 3.

[0030] A groove 12 is formed at the top end of the bottom plate 1. The bottom of the collection bottle 3 corresponds to the groove 12. A bottle cap 6 is provided on the outer surface of the mouth of the collection bottle 3. A second forward thread groove 61 is formed in the inner wall of the bottle cap 6. The second forward thread groove 61 corresponds to the reverse thread groove 31. Both the groove 12 and the collection bottle 3 are provided in multiple groups. The multiple groups of grooves 12 facilitate accommodating multiple groups of collection bottles 3 simultaneously. Rotating the bottle cap 6 makes the second forward thread groove 61 and the reverse thread groove 31 engage with each other, facilitating the sealing of the collection bottle 3.

[0031] A fixing ring 5 is fixedly connected to the outer surface of the conveying pipe 47. A telescopic spring 51 is fixedly connected between the fixing ring 5 and the collection box 2. When the conveying pipe 47 is driven to move up and down under the action of the motor 43, the fixing ring 5 moves along with the conveying pipe 47, thereby driving the telescopic spring 51 to expand and contract. The telescopic spring 51 plays a fixing role.

[0032] During use, the motor 43 drives the threaded rod 44 to rotate, thereby driving the slider 45 to move up and down. The up and down movement of the slider 45 drives the connecting plate 46 and the conveying pipe 47 to move up and down, thereby driving the air collecting hood 48 to move up and down, facilitating the adjustment of the height during waste gas collection to adapt to waste gas emission sources at different heights. Starting the air pump, under the action of the air pump 41, the external waste gas sequentially passes through the air collecting hood 48, the conveying pipe 47, and the connecting hose 411 and enters the air supply pipe 412, and finally is transmitted to the inside of the collection bottle 3 through the air supply pipe 412 to complete the collection. The first filter plate 74 and the second filter plate 75 are used to filter solid particles in the waste gas. After the collection is completed, rotating the collection bottle 3 in the reverse direction makes the collection bottle 3 leave the collection box 2, and then rotating the bottle cap 6 makes the second forward thread groove 61 and the reverse thread groove 31 engage with each other, ensuring good sealing between the bottle cap 6 and the collection bottle 3, facilitating the sealing of the collection bottle 3.
