Description

Technical Field

[0001] The utility model relates to the technical field of gas sampling equipment, in particular to an air pollution prevention and control sampling equipment. Background Art

[0002] An air sampler is an instrument or device used to collect atmospheric pollutants or contaminated air. There are various types, including gas samplers and particulate matter samplers. These can also be categorized by their location as environmental, indoor, and pollution source samplers. Specialized air samplers, such as those designed to collect both gas and particulate matter, can also collect sulfur dioxide and particulate matter, or hydrogen fluoride and particulate matter, facilitating the study of the relationship between sulfur or fluorine in gaseous and solid substances, as well as the detection of airborne bacteria.

[0003] In a Chinese public utility model patent with document number CN219977896U, an atmospheric pollution prevention and control sampling device includes an atmosphere collecting bottle, a rubber bag is bonded to the top of the atmosphere collecting bottle, a sealing cover is threadedly connected to the top of the atmosphere collecting bottle, an air guide frame is bolted to the bottom end on the left side of the atmosphere collecting bottle, the interior of the air guide frame is connected to the interior of the atmosphere collecting bottle, a rotating sleeve is connected to the interior of the air guide frame, and a fan wheel is bolted to the left end of the rotating rod. By injecting air into the interior of the atmosphere collecting bottle, the rubber bag can be flattened and the air inside the rubber bag can be squeezed out to avoid air residue. Then, the air inside the atmosphere collecting bottle is extracted, the rubber bag is allowed to expand again, and the air is sucked in for collection. In this way, the inhaled air will not have other air residues, and the contraction and expansion of the rubber bag can be assisted by tightening the rope.

[0004] The above-mentioned device also has disadvantages when used. For example, when sampling heavily polluted gases, the gas usually contains particulate pollutants and gaseous pollutants. When the two are sampled separately, the sampling device cannot continuously ensure that the sampler is cyclically sampled in a clean state, resulting in more particulate pollutants adhering to the filter when sampling at different time periods, affecting the subsequent accurate sampling and analysis of particulate pollutants and gaseous pollution. Therefore, an atmospheric pollution prevention and control sampling equipment is needed to solve this problem. Utility Model Content

[0035] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0036] like Figures 1-6 As shown, an air pollution prevention and control sampling device provided in this embodiment includes a rack module 1, a mobile module 3 is provided at the bottom of the rack module 1, a sampling power module 2 and a drying power module 5 are respectively provided on both sides of the top of the rack module 1, and a particle sampling mechanism 6 and a gas sampling mechanism 7 are provided on both sides of the sampling power module 2; a cleaning module 4 is also provided on the top of the mobile module 3, and the cleaning module 4 includes a cleaning box 401 and an ultrasonic transducer 402; the sampling power module 2 includes a sampling fan 201 and a telescopic cone ring 202, and the drying power module 5 includes a drying trough 502, a drying fan 501, fan blades 503 and a soft brush 504.

[0037] The sampling fan 201 and the drying fan 501 are both bolted to the vertical plate 101 in the rack module 1, and the telescopic cone ring 202 is squeezed and telescopically installed with the inner walls of the input and output pipes of the sampling fan 201. The sampling fan 201 is used to provide power for exhaust during sampling. The arc structure of the outer wall of the telescopic cone ring 202 is squeezed by the arc of the outer wall of the first docking cover 601 and the second docking cover 701, and then shrinks inward. After entering the inner cavity of the first docking cover 601 and the second docking cover 701, it spreads out and abuts on the inner wall to connect, and leaves in the same way when disconnected.

[0038] The particle sampling mechanism 6 includes a first docking cover 601, a filter 602 and a first support frame 603. The first docking cover 601 is squeezed and sealed with the inner wall of the telescopic cone ring 202. The filter 602 is pressed into the first docking cover 601. The filter 602 can be recycled after cleaning and drying.

[0039] The gas sampling mechanism 7 includes a second docking cover 701, a one-way valve 702, a gas sampling bottle 703 and a second support frame 704. The second docking cover 701 is squeezed and sealed with the inner wall of the telescopic cone ring 202. The one-way valve 702 is installed integrally with the gas sampling bottle 703, and the input end is connected to the valve on the outer wall of the second docking cover 701. There are four groups of gas sampling bottles 703 that need to be replaced regularly. The one-way valve 702 allows one-way entry of gas into the gas sampling bottle 703. When taking out the sampled gas, the gas is taken out through the exhaust port at the bottom of the bottle body.

[0040] The moving module 3 includes a track 301, a servo motor 302, a screw rod 304, a first slider 305, a second slider 306 and a transmission assembly 303. The screw rod 304 is rotatably connected to the inner wall of the track 301, and one end of the outside is connected to the servo motor 302. The first slider 305 and the second slider 306 are respectively slidably connected to the outer wall groove of the track 301. The servo motor 302 drives the cleaning mechanism and the sampling mechanism to move synchronously and align them through the screw rod 304 and the transmission assembly 303. The servo motor 302 is connected to an external controller, and the controller has a built-in cyclic working program that controls the servo motor 302 to rotate and stop at 90°, so that the sampling mechanism can rotate 90° and stop to perform sampling, cleaning and drying operations.

[0041] The first slider 305 is connected to the guide rod 404, the second slider 306 is connected to the lifting cylinder 403, the guide rod 404 is installed in conjunction with the ultrasonic transducer 402, the cleaning box 401 is fixed close to the inner wall of the ultrasonic transducer 402, the transmission assembly 303 is composed of a large wheel on the top, a small wheel on the bottom and a transmission belt, and a drive shaft 8 passes through the inside of the top large wheel. The guide rod 404 guides the vertical movement of the cleaning box 401 to avoid scratching the particle sampling mechanism 6. The ultrasonic transducer 402 is a micro device that provides strong cleaning ability to clean and collect the sampled particulate pollutants.

[0042] The drive shaft 8 is rotatably supported on the rack module 1 through the first support ring 102 and the second support ring 103. The drive shaft 8 is also fixedly mounted on the first support frame 603 and the second support frame 704. The diameter ratio of the large wheel and the small wheel is 2:1. The moving spacing of the four groups of cleaning boxes 401 and the rotational linear speed ratio between the first support frame 603 and the second support frame 704 is 2:1, so the purpose of synchronous alignment can be achieved.

[0043] The output end of the drying fan 501 is sealed and connected to the inner wall of the drying tank 502. The fan blades 503 are rotatably installed on the inner wall of the drying tank 502. The soft brush 504 is glued to the outer wall of the fan blades 503. The fan blades 503 are driven to rotate autonomously by the wind blown by the drying fan 501.

[0044] An ultrasonic generator 104 and an air pump 105 are also fixed to the inner wall of the vertical plate 101 .

[0045] The working principle of this device is: the device is connected to an external power supply and an external control device, and the servo motor 302 drives the screw 304 and the transmission assembly 303 to rotate synchronously, wherein the large and small wheels of the transmission assembly 303 are driven by belts, and the large wheel drives the drive shaft 8 to rotate. The linear speed of the drive shaft 8 is less than the linear speed of the screw 304, so the cycle intervention time of the particle sampling mechanism 6 and the gas sampling mechanism 7 can be stably matched with the access time of the cleaning mechanism at the bottom.

[0046] Each group of particle sampling mechanisms 6 is compressed by squeezing the telescopic cone ring 202 at the input end through the first docking cover 601, and then pops out into the first docking cover 601, connecting to the air inlet of the sampling fan 201. The second docking cover 701 of each group of gas sampling mechanisms 7 is compressed by squeezing the telescopic cone ring 202 at the output end, and then pops out into the second docking cover 701, connecting to the air outlet of the sampling fan 201. The incoming sampling gas is filtered out of particulate pollutants by the filter 602, and the remaining sampling gas enters the gas sampling bottle 703 for storage through the one-way valve 702. The driving shaft 8 drives the particle sampling mechanism 6 and the gas sampling mechanism 7 that have completed sampling counterclockwise to remove the sampling fan 201.

[0047] The particle sampling mechanism 6 is rotated to the top of the cleaning box 401, and the lifting cylinder 403 pushes the cleaning box 401 along the guide rod 404. The liquid inside the cleaning box 401 surrounds the particle sampling mechanism 6. The ultrasonic generator 104 cooperates with the ultrasonic transducer 402 to transmit high-frequency vibration to the internal cleaning liquid to clean the filter 602, thereby achieving the purpose of washing away and collecting particulate pollutants. After completion, the cleaning box 401 is reset, and the particle sampling mechanism 6 continues to be rotated to the drying power module.

[0048] The drying fan 501 emits a hot air source, which passes through the filter 602 and blows on the spiral fan blades 503, driving the fan blades 503 to rotate autonomously, and driving the lightweight soft brush 504 to dry and clean the filter 602, thereby achieving the purpose of drying and cleaning the filter 602. The particle collection mechanism can continue to circulate and move to the sampling fan 201 to continue sampling. In addition, the gas sampling bottle 703 in the gas sampling mechanism 7 can be removed and replaced after use.

[0049] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention based on the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
