[0023] Most of the carbon black mixed gas detection devices on the market use traditional gas analysis technologies, such as spectral analysis, chromatographic analysis, etc.; although these devices can detect carbon black mixed gases, they generally have complex structures, which increases the difficulty of maintenance. In addition, the carbon black mixed gas contains a large number of impurities and particulate matter, which not only affects the accuracy of carbon black mixed gas detection, but also increases the frequency of failure of the detection device, increases the cost of using the detection device, causes economic losses, and reduces the service life of the detection device.
[0024] See also Figure 1-Figure 3 The embodiment of the utility model shown in the figure comprises a box body 10, a sampling chamber 12 and a detection chamber 14. The sampling chamber 12 is responsible for extracting carbon black mixed gas from the environment. A highly sensitive sensor array is installed inside the detection chamber 14 for detecting the composition and concentration of the pretreated gas. Two elastic clamps 11 for installing the sampling chamber 12 and the detection chamber 14 are arranged on both sides of the box body 10. An air inlet pipe 13 is arranged on the side of the sampling chamber 12 away from the detection chamber 14. An exhaust pipe 15 is arranged on the side of the detection chamber 14 away from the sampling chamber 12. The openings on the sides of the sampling chamber 12 and the detection chamber 14 are both installed with connecting plates 20 through the installation components 30, wherein:
[0025] Both sides of the connecting plate 20 are provided with connecting ports 21 for auxiliary gas flow, the insides of the side openings of the sampling cavity 12 and the detection cavity 14 are provided with sealing components 16 for sealing the gas, and the inside of the connecting plate 20 is provided with a filtering component 22 for filtering impurities and particulate matter in the gas.
[0026] First, the specific structure of the sealing assembly 16 is disclosed. The sealing assembly 16 at least includes a mounting ring 161. The mounting ring 161 is provided on the inner wall of the side openings of the sampling chamber 12 and the detection chamber 14. Four sealing plates 162 are connected to the inner wall of the mounting ring 161 on one side close to the opening through a hinge, and the four sealing plates 162 form a cone when close to each other. The outer wall of the four sealing plates 162 is provided with a first elastic member 163 on one side away from the opening, and the other end of the first elastic member 163 is fixedly connected to the inside of the mounting ring 161.
[0027] The improvement lies in that when the connecting port 21 is inserted into the mounting ring 161, the first elastic member 163 is deformed and contracted. At this time, the four sealing plates 162 are separated from the side close to the first elastic member 163, so that the sealing assembly 16 can be opened to allow the gas to flow. Similarly, when the connecting plate 20 is disassembled, the elastic force of the first elastic member 163 is used to tightly fit the four sealing plates 162 to the side close to the first elastic member 163, thereby sealing the side openings of the sampling chamber 12 and the detection chamber 14. This not only improves the safety of the detection device, but also facilitates the later maintenance of the detection device, reduces costs, and thus improves the practicability of the detection device.
[0028] Secondly, the specific structure of the filter component 22 is disclosed. The filter component 22 includes at least a coarse filter layer 221, a high-efficiency filter layer 222 and an activated carbon layer 223. The coarse filter layer 221 is arranged on the side of the connecting plate 20 close to the sampling cavity 12, the activated carbon layer 223 is arranged on the side of the connecting plate 20 close to the detection cavity 14, and the high-efficiency filter layer 222 is arranged in the middle of the connecting plate 20.
[0029] The improvement lies in that large particles of carbon black and other larger impurities are removed through the coarse filter layer 221, and the high-efficiency filter layer 222 and the activated carbon layer 223 are protected from being quickly blocked. The high-efficiency filter layer 222 can capture carbon black particles as small as 0.3 microns and above, as well as other tiny particles, to ensure efficient filtration effects. Finally, the activated carbon layer 223 adsorbs harmful gases in the gas, such as volatile organic compounds (VOCs), and may further adsorb the remaining carbon black particles, which not only improves the safety of carbon black mixed gas detection, but also ensures that the gas entering the detection chamber 14 has a high degree of purity, effectively guarantees the accuracy of the test results, and extends the service life of the device, thereby avoiding economic losses.
[0030] The specific structure of the installation component 30 is disclosed again. The installation component 30 at least includes an installation box 31. The installation box 31 is arranged below the side openings of the sampling cavity 12 and the detection cavity 14. A second elastic member 32 is arranged inside the installation box 31. A connecting block 33 is arranged at the other end of the second elastic member 32. A fixing buckle 34 is arranged on the side of the connecting block 33 away from the second elastic member 32. A pull rod 35 is arranged on the side of the connecting block 33 close to the second elastic member 32. The other end of the pull rod 35 extends to the bottom of the installation box 31. Fixed plates 36 are arranged on both sides of the lower surface of the connecting plate 20. The lower surface of the fixing plate 36 is provided with a fixing groove 37 for snap-fitting with the fixing buckle 34.
[0031] The improvement lies in that: pulling the pull rod 35 causes the second elastic member 32 to deform and shrink, and the fixing buckle 34 also enters the interior of the installation box 31. At this time, the connecting port 21 is inserted into the interior of the side openings of the sampling chamber 12 and the detection chamber 14, and the pull rod 35 is loosened. Through the rebound force of the second elastic member 32, the fixing buckle 34 is popped out of the interior of the installation box 31 and snap-fitted with the fixing groove 37, so that the installation of the connecting plate 20 is completed. It is not only simple to operate and easy to install and disassemble, but also convenient for cleaning or replacing the filter component 22 at a later time, reducing the cost of using the detection device and avoiding economic losses. It also improves the flexibility of using the detection device, thereby improving the practicality of the detection device.
[0032] In order to open the sealing assembly 16 and allow the gas to enter the detection chamber 14 for convenient gas detection, the side of the connection port 21 away from the connection plate 20 is in a truncated cone shape.
[0033] The improvement lies in that: through the truncated cone shape at one end of the connecting port 21, the four sealing plates 162 are moved closer to the inner wall of the mounting ring 161, and at the same time, the first elastic member 163 is deformed and contracted. At this time, the four sealing plates 162 are separated by one end that is close to each other, and the gas inside the sampling chamber 12 flows to the inside of the detection chamber 14 through the vacuum operation of the detection chamber 14. This not only simplifies the operation, improves the working efficiency of the carbon black mixed gas detection, avoids wasting time, but also improves the flexibility of the use of the carbon black mixed gas detection device.
[0034] In summary, the working principle of the present scheme is as follows: first, when the connecting port 21 is inserted into the interior of the mounting ring 161, the first elastic member 163 is deformed and contracted. At this time, the four sealing plates 162 are separated from one side close to the first elastic member 163, so that the sealing assembly 16 can be opened to allow the gas to flow. At the same time, the pull rod 35 is pulled to cause the second elastic member 32 to deform and contract, and the fixing buckle 34 also enters the interior of the mounting box 31. At this time, the connecting port 21 is inserted into the interior of the side openings of the sampling cavity 12 and the detection cavity 14, and the pull rod 35 is released. The fixing buckle 34 is ejected out of the mounting box 31 by the resilience of the second elastic member 32. The connecting plate 20 is fixed inside and snap-fitted with the fixing groove 37 to stabilize the position of the connecting plate 20. Then, the gas flows to the inside of the sampling chamber 12 through the air inlet pipe 13. Then, the gas in the detection chamber 14 is evacuated to make the gas in the sampling chamber 12 flow from the inside of the connecting plate 20 to the inside of the detection chamber 14. Here, the gas is filtered by the coarse filter layer 221, the high-efficiency filter layer 222 and the activated carbon layer 223 inside the connecting plate 20. Finally, the filtered gas is detected by the detection chamber 14. After completion, the gas in the detection chamber 14 is discharged through the exhaust pipe 15 to complete the detection work of the carbon black mixed gas detection device.
