Abstract
Description
Technical Field
[0001] This utility model relates to the field of air sampling equipment technology, and in particular to an air sampling and detection device. Background Technology
[0002] The main function of air sampling and testing equipment is to collect air samples for further detailed analysis and testing. It uses equipment such as sampling pumps to draw air into the sampler, collect it in a specific container, and then send it to the laboratory for analysis.
[0003] Currently, the most commonly used air sampling and testing equipment is the atmospheric sampler. During use, the transmission line is directly plugged into the side tube of the gas line or sampling bottle. This can easily lead to loosening or leakage of the transmission line, which can affect subsequent testing.
[0004] To address the aforementioned problems, this utility model document proposes an air sampling and detection device. Utility Model Content
[0005] This invention provides an air sampling and testing device that solves the problem that in the prior art, when the transmission pipeline is directly plugged into the side tube of the gas pipeline or sampling bottle during use, the transmission pipeline is prone to loosening or leakage, which affects subsequent testing.
[0006] This utility model provides the following technical solution:
[0007] An air sampling and detection device, comprising:
[0008] The atmospheric sampler body has a matching air passage tube and groove on its top. A sampling bottle is placed in the groove. A drying bottle with large-particle desiccant is located on one side of the atmospheric sampler body. A bottle cap is threaded to the top of the drying bottle. The input tube at the top of the bottle cap is connected to the side opening tube of the sampling bottle through a first delivery tube. The output tube at the top of the bottle cap is connected to the air passage tube through a second delivery tube. Fasteners for improving sealing are provided at both ends of the first and second delivery tubes.
[0009] The bottom of the atmospheric sampler body is provided with a support plate, and the bottom of the support plate is hinged with three adjustable legs in a circular array.
[0010] In one possible design, the fastener includes a clamping ring fitted onto both ends of the first and second conveying pipes. Two sealing blocks are fixedly provided at the sealing end of the clamping ring. One of the sealing blocks has a first threaded hole internally threaded with a first screw bolt for tightening the clamping ring. One end of the first screw bolt passes through the first threaded hole and is rotatably connected to the inner wall of the other sealing block via a bearing.
[0011] In one possible design, a rubber gasket is fixedly provided on the inner ring of the clamping ring, and the inner wall of the rubber gasket is in contact with the outer wall of the conveying pipe.
[0012] In one possible design, the adjustable support leg includes a hollow base rod hinged to the bottom of the support plate. A movable rod is slidably disposed within the cavity of the hollow base rod. The other end of the movable rod extends outside the hollow base rod and is fixedly disposed with a rubber ball pad. A second threaded hole on the hollow base rod is internally threaded with a second bolt for locking the extension length of the movable rod.
[0013] In one possible design, a hollow block is fixedly installed on one side of the atmospheric sampler body, an L-shaped insert is inserted into the cavity of the hollow block, and a fixing bracket for placing a desiccant bottle is fixedly installed on one side of the L-shaped insert.
[0014] In one possible design, a rectangular block is fixedly disposed at the center of the top of the support plate to facilitate fixing the air sampler body, and a slot for inserting and fixing the rectangular block is disposed at the bottom of the air sampler body.
[0015] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.
[0016] The working principle and usage process of this technical solution are as follows:
[0017] During equipment installation, adjust the extension length of the three movable rods within the corresponding hollow base rods. Once the extension length of the movable rods is properly adjusted, tighten the second bolt to lock the extension length of the movable rods, ensuring the support legs are stable and allowing the equipment to be placed stably. The rubber ball pads can increase friction and cushioning with the ground. Then, align the slot at the bottom of the atmospheric sampler body with the rectangular block at the center of the top of the support plate to fix the atmospheric sampler body to the support plate. Place the drying bottle on the mounting bracket and insert the L-shaped insert into the cavity of the hollow block to fix the drying bottle. Place the sampling bottle in the groove. Then, use the first delivery pipe to connect the side opening of the sampling bottle to the input pipe at the top of the drying bottle cap, and use the second delivery pipe to connect the output pipe at the top of the drying bottle cap to the gas pipe. Finally, tighten the corresponding clamping rings by tightening the four first bolts to ensure the rubber gasket rings fit tightly against the delivery pipes and improve the sealing performance.
[0018] After the air sampler is activated, it generates suction, drawing outside air into the sampling bottle. During the airflow, the air flows from the side opening of the sampling bottle through the first delivery tube into the drying bottle. The large-particle desiccant inside the drying bottle dries the air, removing moisture. The dried air then flows from the output tube at the top of the drying bottle cap through the second delivery tube into the air path tube, and is finally collected by the sampler. After collecting a certain amount of air sample, the air sampler is shut off, and the air sample is sent to the laboratory for detailed analysis and testing.
[0019] This utility model has the following beneficial effects:
[0020] In this invention, the fasteners installed at both ends of the first and second delivery pipes, through the cooperation of the clamping ring and the rubber gasket ring, effectively prevent the transmission pipeline from loosening or leaking, ensuring the airtightness of the air sampling process and improving the accuracy of subsequent test results; by setting up a drying bottle, the collected air is pre-treated for drying, avoiding the interference of moisture with subsequent tests, and improving the accuracy and efficiency of subsequent analysis and testing.
[0021] The adjustable support leg design in this invention allows for adjustment of the support leg length according to different terrain conditions, ensuring stable placement of the equipment and enhancing its stability in various environments. The atmospheric sampler body is fixed to the support plate via slots and rectangular blocks, while the drying bottle is fixed via L-shaped inserts and hollow blocks, making the installation process simple and convenient.
