Technical Field
[0001] This utility model relates to the field of industrial waste gas sampling technology, and in particular to a sampling device for industrial waste gas detection. Background Technology
[0002] Industrial waste gas is a gaseous substance containing pollutants generated during industrial production processes. These gases can cause significant harm to the environment and human health. Sampling devices for industrial waste gas detection are used to collect and analyze waste gas for subsequent testing. However, common industrial waste gas sampling devices often have poor performance in removing impurities from the waste gas. When waste gas is drawn into the sampling chamber, dust and impurities are also drawn in. This mixture of dust and impurities affects subsequent test results and hinders the quick installation, removal, replacement, and cleaning of filters. Furthermore, after sampling, because waste gas contains various solid particles, droplets, and gaseous chemicals, pollutants remain on the inner wall of the sampling chamber even after it is emptied. Therefore, cleaning of the sampling chamber is necessary to prevent impacting subsequent test results. Thus, we propose an industrial waste gas sampling device to address this problem. Utility Model Content
[0003] The purpose of this invention is to provide a sampling device for industrial waste gas detection to solve the problems mentioned in the background art.
[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

Each disassembly component includes: a pull plate and a housing, a plug and a connecting rod fixedly installed at the bottom of the pull plate, the plug movably inserted into the top of the housing, a connecting block fixedly installed at the bottom of the connecting rod, and both the connecting rod and the connecting block slidably installed inside the housing. Two sets of connecting shafts are fixedly installed on one side of the housing, and a sliding plate is fixedly installed at one end of each of the two sets of connecting shafts. The two sets of connecting shafts and one sliding plate slidably installed inside the placement slots, and a plug plate is fixedly installed at one end of the sliding plate, the plug plate movably inserted into the filter screen. A sampling chamber is provided on one side of the air inlet chamber.
[0006] Preferably, the sampling chamber is provided with a rotating shaft inside, and three sets of collars are fixedly sleeved on the outside of the rotating shaft. Two sets of fixing rods are fixedly installed on the outside of each of the three sets of collars. The same set of cleaning brush plates is fixedly installed at one end of the three sets of fixing rods on the same side, and both sets of cleaning brush plates are in movable contact with the inner wall of the sampling chamber.

[0008] Preferably, each of the two sets of housings is provided with a spring 1 inside, and the two ends of the two sets of spring 1 are respectively fixedly connected to the corresponding connecting block and the inner wall of one side of the housing. The four sets of connecting shafts are each fitted with a spring 2 on the outside, and the two ends of the two sets of spring 2 located on the same side are respectively fixedly connected to the inner wall of one side of the corresponding sliding plate and the placement groove.
[0009] Preferably, an air intake pipe is fixedly installed on the outside of the air intake chamber, and a cleaning pipe is fixedly installed at one end of the sampling chamber.
[0010] Preferably, four sets of support rods and one set of fixing brackets are fixedly installed at the bottom of the box and the sampling chamber, respectively.

[0011] In this utility model, an industrial waste gas sampling device is provided with a disassembly assembly and a filter screen. By pulling two sets of pull plates horizontally upward, the two sets of pull plates cause the insert blocks to detach from the inside of the housing, while simultaneously driving the connecting rod and the connecting block to stretch the spring. Then, by pulling the pull plates horizontally left and right, the two sets of pull plates cause the housing to move, which in turn causes the corresponding connecting shaft and sliding plate to move, while simultaneously squeezing the second spring. This causes the two sets of insert plates to detach from the inside of the filter screen on both sides. At this point, the filter screen can be disassembled, cleaned, and replaced. This structure is simple and easy to operate, enabling quick installation and disassembly of the filter screen. Timely cleaning and replacement of the clean filter screen can effectively remove impurities and particulate matter in the waste gas, preventing them from clogging or contaminating the detection equipment, and maintaining its good filtration effect, thereby ensuring the accuracy and reliability of the detection results.
[0012] This invention discloses an industrial waste gas sampling device comprising a motor, a rotating shaft, collars, a fixing rod, cleaning brushes, and a cleaning pipe. Water is introduced into the sampling chamber through the cleaning pipe. The motor drives the rotating shaft, which in turn rotates the three sets of collars on the outer side. This allows the two sets of cleaning brushes to effectively clean the inner wall of the sampling chamber, removing residual waste gas pollutants and impurities. This prevents cross-contamination of subsequent waste gas samples, ensuring the purity and accuracy of each sample, improving detection precision, reducing the erosion and damage of corrosive waste gas components to the chamber wall, slowing down the aging of the equipment, and extending the service life of the sampling chamber and the entire sampling device.

[0019] In this embodiment, a rotating shaft 8 is provided inside the sampling chamber 7. Three sets of collars 9 are fixedly sleeved on the outside of the rotating shaft 8. Two sets of fixing rods 10 are fixedly installed on the outside of each of the three sets of collars 9. One end of each of the three sets of fixing rods 10 on the same side is fixedly installed with the same set of cleaning brush plates 11. Both sets of cleaning brush plates 11 are in movable contact with the inner wall of the sampling chamber 7, which facilitates cleaning of the inner wall of the sampling chamber 7. The rotating shaft 8 is rotatably installed on the inner walls of both sides of the sampling chamber 7. A motor 15 is fixedly installed on one side of the sampling chamber 7. The output shaft of the motor 15 is fixedly connected to the rotating shaft 8. A connecting pipe 12 is fixedly installed at the bottom of the air inlet chamber 2. An air pump 16 is fixedly installed at one end of the connecting pipe 12. An air outlet pipe 13 is fixedly installed at one end of the air pump 16. One end of the air outlet pipe 13 is fixedly connected to the sampling chamber 7, which facilitates the rotation of the rotating shaft 8, facilitates the cleaning of the sampling chamber 7, and facilitates the entry of filtered gas into the interior of the sampling chamber 7.
[0020] In this embodiment, spring 605 is provided inside both sets of housings 606. The two ends of the two sets of spring 605 are fixedly connected to the corresponding connecting block 604 and the inner wall of one side of housing 606, respectively.
