Description

Technical Field

[0001] The utility model relates to the technical field of smoke sampling, and more specifically to a high-humidity and low-concentration smoke sampling tube. Background Art

[0002] The smoke generated in industrial production is the main pollutant causing air pollution. In order to reduce air pollution, it is necessary to understand and control the smoke emissions of enterprises, which requires the use of smoke samplers. The smoke sampler can collect and analyze the concentration, humidity, excess air coefficient, flow rate, etc. of the smoke. The smoke sampling tube is the core component of the smoke sampler, which is directly related to the accuracy of the detection results of the smoke sampler. It usually includes a sampling head, a pipeline, a sampler and a data recording system.

[0003] In the process of using the existing high-humidity and low-concentration smoke sampling tube, the sampling nozzle at the end of the sampling tube is mostly set in an arc-shaped curved structure, which makes it extremely inconvenient to adjust the angle of the sampling nozzle when sampling in different scene environments, and the adjustability is also poor when used for smoke exhaust ports of various heights, which makes the sampling nozzle unable to fit the smoke exhaust port more effectively, causing certain troubles in actual use;

[0004] In addition, the existing high-humidity and low-concentration smoke sampling tubes usually have a certain filter component at the end, so that it can filter impurities that cannot be detected. However, the filter component used therein usually needs to be replaced regularly, and the existing replacement method mostly involves disassembling the sampling head and then replacing the filter component behind it, which brings a certain degree of cumbersomeness to the replacement work and causes many inconveniences to the use.

[0005] In view of this, we propose a high-humidity and low-concentration smoke sampling tube. Utility Model Content

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the advantages of the utility model are: when the smoke sampling tube is used, the limit bolt 1 can be loosened to keep it away from the adjustment slot 1, and then the rotating tube and the sleeve tube carrying the collection head can be rotated, so that it can be used more conveniently for smoke emission pipes in various directions. Secondly, when testing at a higher place, the limit bolt 2 can be loosened and kept away from the limit slot, and then the sleeve tube can be pulled and re-positioned in the adjustment slot 2 at the appropriate position using the limit bolt 2, thereby improving its adjustability in use. Secondly, the rotating motor can drive the rotating rod to rotate. During the rotation process, since the limit column is in the through slot on the outer wall of the rotating rod, the plasticity of the stainless steel bellows can be better matched to fine-tune the angle of the collection head, so that it is more in line with the smoke emission port, thereby effectively improving the practical performance of the smoke sampling tube.

[0018] When the filter plate needs to be replaced, you only need to rotate the limit rod to move it away from the filter plate to release the limit on the filter plate, and then pull the pull column to take out the filter plate for replacement. During installation, the opposite is true, which reduces the tediousness of personnel disassembling the collection head to replace the filter plate, effectively improves the replacement efficiency of personnel, and makes installation simpler and more convenient.

[0030] In some embodiments: the sampler 110 is the main part of the smoke sampling tube, which usually includes an exhaust device, a flow control device, a sampling pump, etc. Through the exhaust device of the sampler, air is drawn into the pipeline, and the smoke particles are captured by the filter plate 470 of the sampling head, and finally sent to the sampler for analysis. The sampler 110 is usually equipped with a data recording system for recording important parameters in the sampling process, such as sampling time, flow rate, temperature, etc., for subsequent data analysis and result verification. Secondly, an analytical instrument is set outside. In general, the smoke sampling tube captures smoke particles in the air through the sampling head 420, and sends them to the analytical instrument for detection and analysis through the sampler 110, thereby realizing the quantitative collection and monitoring of smoke particles in the air. The analytical instrument is set outside and used in conjunction with the smoke sampling tube. The above all belong to the prior art.

[0031] The connecting tube 120 is internally rotatably connected with a rotating tube 200, the outer wall of the rotating tube 200 is sleeved with a sleeve tube 300, the outer wall inner cavity of the sleeve tube 300 is provided with an electric heating wire 310, the rear outer wall of the sleeve tube 300 is provided with a connecting plate 320, the side wall of the connecting plate 320 is provided with a second connecting block 330, the internal thread sleeve of the second connecting block 330 is sleeved with a second limiting bolt 340, the rear outer wall of the connecting plate 320 is provided with a rotating motor 350, and the output end of the rotating motor 350 is connected with a rotating rod 360;

[0033] The left end of the sleeve tube 300 is threadedly sleeved with a mounting sleeve 400 , a side wall of the mounting sleeve 400 is provided with a stainless steel bellows 410 , and a collection head 420 is threadedly connected to the end of the stainless steel bellows 410 .

[0034] In some embodiments: the sampling head 420 is the front end portion of the smoke sampling tube, which usually adopts an arc-shaped design to reduce airflow resistance so that the smoke can smoothly enter the pipeline for sampling. The stainless steel bellows 410 has a certain plasticity, which is convenient for adjusting the angle of the collection head 420 in conjunction with the rotation of the rotating rod 360.

[0035] Specifically, a connecting block 130 is disposed on the side wall of the connecting tube 120 , and a limiting bolt 140 is sleeved inside the connecting block 130 , so as to limit the rotation tube 200 after the rotation adjustment.

[0036] Furthermore, an adjustment groove 1 210 and an adjustment groove 220 are provided on the circumferential outer wall of the rotating tube 200. The adjustment groove 1 210 matches with the limit bolt 140, and the adjustment groove 220 matches with the limit bolt 2 340, so as to facilitate the limiting of the sleeve tube 300 after the length is adjusted.

[0037] In some embodiments, movable recesses and protrusions may be provided on the inner walls of the rotating tube 200 and the sleeve tube 300 to provide position limiting guidance during the rotation of the rotating tube 200 and the sleeve tube 300, thereby preventing the sleeve tube 300 from idling and being unable to adjust when the rotating tube 200 is rotated.

[0038] Furthermore, a guide column 430 is provided on the circumferential outer wall of the collection head 420, and a through groove 370 matching the guide column 430 is opened on the outer wall of the rotating rod 360, so as to facilitate the adjustment of the collection head 420.

[0039] Furthermore, a threaded rod 440 is provided on the front outer wall of the collection head 420 , and a limiting rod 450 is provided on the outer wall of the threaded rod 440 to facilitate limiting the filter plate 470 .

[0040] It is worth noting that a snap-in groove 460 is provided on the front outer wall of the collection head 420 , and a filter plate 470 is arranged inside the snap-in groove 460 , which makes it easier to filter out undetectable impurities.

[0041] It is worth noting that a glass fiber filter membrane is disposed inside the filter plate 470, and a pull column 480 is disposed on the front outer wall of the filter plate 470 to facilitate disassembly and removal.

[0042] In some embodiments, the device can use an external conventional power source as the power source, and a controller for controlling the device is provided on the side wall of the sampler 110. All of the above belong to the prior art.

[0043] In addition, the circuits, electronic components and modules involved in the utility model are all existing technologies and can be fully implemented by those skilled in the art.

Secondly, when testing at a higher place, the limit bolt 2 340 is loosened and kept away from the limit slot, and then the sleeve tube 300 is pulled and re-limited in the adjustment slot 220 at the appropriate position using the limit bolt 2 340, so as to more flexibly improve its adjustability. Secondly, the rotating motor 350 can drive the rotating rod 360 to rotate. During the rotation process, since the limiting column 450 is in the through groove on the outer wall of the rotating rod 360, the plasticity of the stainless steel bellows 410 can be better matched to fine-tune the angle of the collection head, so that it is more in line with the smoke exhaust port, and the practical performance of the smoke sampling tube is effectively improved. When the filter plate 470 needs to be replaced, it is only necessary to rotate the limiting rod 450 to move it away from the filter plate 470 to release the limit on the filter plate 470, and then pull the pulling column 480 to take out the filter plate 470 for replacement, and vice versa during installation, thereby reducing the tediousness of personnel disassembling the collection head 420 to replace the filter plate 470, and effectively improving the replacement efficiency of personnel.
