Description

Technical Field

[0001] The present invention belongs to the technical field of gas detection, and particularly relates to a micro PID gas chromatograph analyzer. Background Technique

[0002] A gas chromatograph analyzer is based on a system composed of a stationary phase and a mobile phase, that is, different distribution coefficients in a chromatographic column. Then, the measured sample gas is separated according to its components, and the chromatographic peaks of each component gas are converted into electrical signals by a detector and output as voltage or current through an electronic amplifier.

[0003] At present, when the used gas chromatograph analyzer is in use, since the pipes are connected by means of threads or the like between the pipes, there will be a certain gap between them. When the measured sample gas passes through the connection, leakage will occur. On the one hand, the leaked gas will cause waste of resources. If it is toxic inside, it will cause a certain degree of air pollution. On the other hand, the leaked gas may cause deviation in the detection results. And when the gas chromatograph analyzer is working, high temperature will be generated inside, and the existing heat dissipation mechanism cannot self-regulate according to the temperature of the device.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] 1. In the present invention, by providing a connection component and a sealing component, the limiting plate is respectively pulled towards the outside of the connection ring. Then, after aligning one end of the air delivery pipe with the side wall of the connection ring, under the action of the connection spring, the sliding rod UI will be pulled to its original position by the limiting plate. Then, the positioning plate is pulled outwards. At this time, the positioning plate will drive the sliding rod to slide on the inner wall of the limiting plate, and at the same time, it will also drive the threaded rod to move on the inner wall of the threaded sleeve. Furthermore, the threaded sleeve drives the moving ring to slide on the outer surface of the air inlet pipe through the rotating ring. At this time, the moving ring will squeeze the spring rod. When the side wall of the positioning plate moves outside the side wall of the air delivery pipe, the spring rod will automatically extend, thereby driving the moving ring to move, so that the threaded sleeve rotates on the inner wall of the through hole through the rotating ring, and the threaded rod pulls the positioning plate back through the sliding rod, thereby connecting one end of the air delivery pipe to the side wall of the connection ring. Since there is an additional air delivery pipe between the positioning plate and the connection ring, the position of the threaded rod will move, and thus drive the push plate to move in the fixed box through the connecting plate. At this time, the push plate will squeeze the main airbag, and the gas inside the squeezed main airbag will flow into the sealing airbag through the air pipe. When the sealing airbag expands, part of the airbag will run out from the slot on the side wall of the connection ring, thereby blocking the gap between the connection ring and the air delivery pipe, facilitating the disassembly and assembly of the pipes, improving the installation convenience of the chromatograph analyzer, and automatically sealing the connection after installation to avoid air leakage during the air delivery process, which may affect the experimental data.

[0027] 2. In the present invention, by providing a heat dissipation component and an adjustment component, when the machine body is working, the motor drives the rotating box to rotate through the rotating rod. At this time, the rotating box will drive the fan blades to rotate, thereby dissipating heat from the machine body. When the rotating box rotates, it will drive the scraper to rotate through the connecting rod and the fixed plate, thereby cleaning the dust on the dust-proof net. When the temperature sensor senses an increase in the temperature inside the machine body, it will control the motor to work through the control system. At this time, the motor will drive the driving bevel gear to rotate through the movable rod, and thus, under the action of the driven bevel gear, the support rod will rotate under the limitation of the limit frame, thereby changing the angle of the fan blades, and further increasing the air outlet rate of the fan blades, automatically changing the heat dissipation efficiency of the heat dissipation component according to the temperature of the machine body, avoiding damage to internal components due to excessive temperature inside the machine body, and further improving the heat dissipation efficiency of the chromatograph analyzer.

[0028] 3. In the present invention, by providing an atomizing component, during the rotation of the scraper, when the scraper rotates to an appropriate position, it will squeeze the top block. The squeezed top block will drive the pressure plate to move upward in the placement box under the limit of the telescopic spring, thereby squeezing the liquid storage bladder. At this time, the cooling water contained in the liquid storage bladder will be sprayed out from the nozzle through the connecting pipe to cool the air blown by the fan blades, and at the same time, it will dust the dust brushed up by the scraper. While dissipating heat, atomizing the surrounding area can reduce the temperature around the chromatograph analyzer, thereby improving the heat dissipation effect of the machine body. While atomizing, it also performs a dust reduction treatment on the dust brushed up by the dust-proof net, preventing the dust from adhering to the dust-proof net again and affecting the heat dissipation effect.

A threaded sleeve 611 is fixedly installed on the inner wall of the rotating ring 612. The threaded rod 62 passes through the inside of the threaded sleeve 611. The inner wall of the threaded sleeve 611 is threadedly connected to the outer surface of the threaded rod 62. The sealing component 7 includes a partition plate 71 and a fixed box 74. The outer surface of the partition plate 71 is fixedly connected to the inner wall of the connecting ring 5. A sealing airbag 72 is fixedly installed on the side wall of the partition plate 71. An air pipe 73 is communicated and installed on the side wall of the sealing airbag 72.

[0041] Specific embodiments thereof are as follows: Pull the limiting plates 64 outwardly to the outside of the connecting ring 5 respectively. Then, after aligning one end of the air delivery pipe with the side wall of the connecting ring 5, under the action of the connecting spring 68, the sliding rod 61 will be pulled back to its original position by the limiting plate 64. Then, pull the positioning plate 63 outward. At this time, the positioning plate 63 will drive the sliding rod 61 to slide on the inner wall of the limiting plate 64, and at the same time, it will also drive the threaded rod 62 to move on the inner wall of the threaded sleeve 611. As a result, the threaded sleeve 611 drives the moving ring 65 to slide on the outer surface of the air inlet pipe 4 through the rotating ring 612. At this time, the moving ring 65 will squeeze the spring rod 66. When the side wall of the positioning plate 63 moves outside the side wall of the air delivery pipe, the spring rod 66 will automatically extend, thereby driving the moving ring 65 to move, so that the threaded sleeve 611 rotates on the inner wall of the through hole 610 through the rotating ring 612, so that the threaded rod 62 pulls the positioning plate 63 back through the sliding rod 61, thereby connecting one end of the air delivery pipe to the side wall of the connecting ring 5. Since there is an additional air delivery pipe between the positioning plate 63 and the connecting ring 5, the position of the threaded rod 62 will move, thereby driving the push plate 75 to move in the fixed box 74 through the connecting plate 77. At this time, the push plate 75 will squeeze the main airbag 76. The gas inside the squeezed main airbag 76 will flow into the sealing airbag 72 through the air pipe 73. When the sealing airbag 72 expands, part of the airbag will run out from the slot on the side wall of the connecting ring 5, thereby blocking the gap between the connecting ring 5 and the air delivery pipe.

The adjusting component 8 includes a motor 81, the side wall of the motor 81 is fixedly connected to the inner wall of the rotating box 27, a movable rod 82 is fixedly installed at the output end of the motor 81, a driving bevel gear 83 is fixedly installed on the outer surface of the movable rod 82, a limiting frame 84 is fixedly installed on the inner wall of the rotating box 27, a support rod 85 is rotatably installed on the inner wall of the limiting frame 84, a driven bevel gear 86 is fixedly installed at one end of the support rod 85, the other end of the support rod 85 extends outside the rotating box 27, and a fan blade 28 is fixedly installed at the other end of the support rod 85.

[0043] The specific embodiment is as follows: When the machine body 1 is working, the motor 25 drives the rotating box 27 to rotate through the rotating rod 26. At this time, the rotating box 27 drives the fan blade 28 to rotate, so as to dissipate heat from the machine body 1. When the rotating box 27 rotates, it drives the scraper 211 to rotate through the connecting rod 29 and the fixing plate 210, so as to clean the dust on the dust-proof net 22. When the temperature sensor senses that the temperature inside the machine body 1 increases, it controls the motor 81 to work through the control system. At this time, the motor 81 drives the driving bevel gear 83 to rotate through the movable rod 82, so that the support rod 85 rotates under the limitation of the limiting frame 84 under the action of the driven bevel gear 86, so as to change the angle of the fan blade 28, and further increase the air outlet rate of the fan blade 28.

[0044] The atomization component 3 includes a placement box 31, the lower surface of the placement box 31 is fixedly connected to the upper surface of the fixed cover 21, a telescopic spring 32 is fixedly installed on the inner wall of the placement box 31, one end of the telescopic spring 32 is fixedly installed with a pressing plate 33, a top block 34 is fixedly installed on the side wall of the pressing plate 33, one end of the top block 34 extends outside the side wall of the placement box 31, a liquid storage bladder 35 is fixedly installed on the upper surface of the pressing plate 33, the upper surface of the liquid storage bladder 35 is fixedly connected to the upper inner wall of the placement box 31, connecting pipes 36 are communicated and installed on both side walls of the liquid storage bladder 35, one end of each connecting pipe 36 is communicated and installed with a spray head 37, and one end of the spray head 37 extends outside the side wall of the placement box 31.

[0045] The specific embodiment is as follows: during the rotation of the scraping plate 211, when the scraping plate 211 rotates to an appropriate position, it will squeeze the top block 34. The squeezed top block 34 will drive the pressing plate 33 to move upward in the placement box 31 under the limitation of the telescopic spring 32, so as to squeeze the liquid storage bladder 35. At this time, the cooling water contained in the liquid storage bladder 35 will be sprayed out from the spray head 37 through the connecting pipe 36 to cool the wind blown by the fan blade 28, and at the same time, the dust lifted by the scraping plate 211 will be dust-settled.

[0046] Working principle: Pull the limit plates 64 outward on the outer side of the connecting ring 5 respectively. Then, after aligning one end of the air delivery pipe with the side wall of the connecting ring 5, under the action of the connecting spring 68, the sliding rod 61 will be pulled to its original position by the limit plate 64. Then, pull the positioning plate 63 outward. At this time, the positioning plate 63 will drive the sliding rod 61 to slide on the inner wall of the limit plate 64, and at the same time, it will also drive the threaded rod 62 to move on the inner wall of the threaded sleeve 611. As a result, the threaded sleeve 611 drives the moving ring 65 to slide on the outer surface of the air inlet pipe 4 through the rotating ring 612. At this time, the moving ring 65 will squeeze the spring rod 66. When the side wall of the positioning plate 63 moves outside the side wall of the air delivery pipe, the spring rod 66 will automatically extend, thereby driving the moving ring 65 to move, so that the threaded sleeve 611 rotates on the inner wall of the through hole 610 through the rotating ring 612, so that the threaded rod 62 pulls the positioning plate 63 back through the sliding rod 61, thereby connecting one end of the air delivery pipe to the side wall of the connecting ring 5. Since there is an additional air delivery pipe between the positioning plate 63 and the connecting ring 5, the position of the threaded rod 62 will move, thereby driving the push plate 75 to move in the fixed box 74 through the connecting plate 77. At this time, the push plate 75 will squeeze the main airbag 76. The gas inside the squeezed main airbag 76 will flow into the sealing airbag 72 through the air pipe 73. When the sealing airbag 72 expands, part of the airbag will run out of the slot on the side wall of the connecting ring 5, thereby blocking the gap between the connecting ring 5 and the air delivery pipe. After the air enters the interior of the machine body 1, the micro pre-concentration module concentrates the VOCs gas from the air, then releases the VOCs gas through heating, separates each gas through the micro gas chromatography column, and detects the content of each gas component through the high-precision PID detector. Then, the data is displayed on the computer. When the machine body 1 is working, the motor 25 drives the rotating box 27 to rotate through the rotating rod 26. At this time, the rotating box 27 will drive the fan blade 28 to rotate, thereby dissipating heat from the machine body 1. When the rotating box 27 rotates, it will drive the scraping plate 211 to rotate through the connecting rod 29 and the fixing plate 210, thereby cleaning the dust on the dust-proof net 22. When the temperature sensor senses an increase in the temperature inside the machine body 1, it will control the motor 81 to work through the control system. At this time, the motor 81 will drive the driving bevel gear 83 to rotate through the movable rod 82, so that under the action of the driven bevel gear 86, the support rod 85 will rotate under the limit of the limit frame 84, thereby changing the angle of the fan blade 28, and thus increasing the air outlet rate of the fan blade 28. During the rotation of the scraping plate 211, when the scraping plate 211 rotates to an appropriate position, it will squeeze the top block 34. The squeezed top block 34 will drive the pressing plate 33 to move upward in the placement box 31 under the limit of the telescopic spring 32, thereby squeezing the liquid storage bladder 35. At this time, the cooling water contained in the liquid storage bladder 35 will be sprayed out from the nozzle 37 through the connecting pipe 36 to cool the air blown by the fan blade 28, and at the same time, it will reduce the dust raised by the scraping plate 211.
