Description

Technical Field

[0001] This invention relates to the field of atmospheric sampling, specifically to an atmospheric sampling device with a filtration structure. Background Technology

[0002] Atmospheric sampling is the process of collecting a representative sample of gas or particulate matter from the ambient air using scientific methods, so that it can be taken to a laboratory for analysis and measurement to assess the overall air quality of a region and determine whether it meets the ambient air quality standards.

[0003] Ambient air is a complex mixture containing a large amount of particulate matter. This particulate matter can wear down air pumps, clog flow meters and small pipe valves, leading to inaccurate sampling flow and equipment damage. Typically, filters are installed to remove particulate matter. Existing atmospheric sampling devices have a movable scraper on one side of the filter to remove particulate matter. Since air first enters the filter chamber and then passes through the filter, if the scraper continuously removes particulate matter from the filter, it can cause particulate matter to accumulate inside the filter chamber. As the amount of particulate matter increases, it can still clog the filter, but this method lacks the function of collecting particulate matter. Summary of the Invention

Water in the storage box is used to collect the particulate impurities, preventing them from flying or accumulating, thus ensuring the filter plate can properly filter the air and achieving rapid cleaning and particulate collection.

[0016] This invention, through a cleaning mechanism, enables the pulley rod to pull the scraper into the housing when it moves to the stepped end of the guide rail. The rebound force of the tension spring brings the two receiving plates closer together, thus scraping off the particulate impurities on the scraper. This facilitates the scraper brush to push the particulate impurities off the receiving plates, thereby improving the recovery efficiency of particulate impurities and preventing the leakage of particulate impurities.

[0017] This invention, through a material receiving mechanism, enables the comb plate to push out residual particulate impurities inside the scraper when the scraper enters the water storage box, and causes the comb plate to swing back and forth, while the scraper swings synchronously in the water, so that the particulate impurities inside the scraper are quickly discharged, thereby achieving the effect of rapid cleaning of the scraper and facilitating continuous cleaning of the filter plate.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-9 The illustration shows an atmospheric sampling device with a filtration structure, including a housing 1 and an air inlet box 2 fixedly installed inside the housing 1. Filter plates 3 are fixedly installed on both sides of the air inlet box 2, and an exhaust pipe 4 extending to the outside of the housing 1 is fixedly installed on the outside of the air inlet box 2. An air inlet pipe 5 is fixedly installed at the bottom of the housing 1, allowing air to enter the housing 1 through the air inlet pipe 5. The air is then filtered by the two filter plates 3 to intercept particulate impurities in the air, and the filtered air is discharged from the exhaust pipe 4. The device also includes a collection mechanism for scraping and collecting particulate impurities on the filter plates 3, and the collection mechanism is installed between the housing 1 and the air inlet box 2.

[0022] The collection mechanism includes two scrapers 6 symmetrically arranged on the outside of the air inlet box 2. The two scrapers 6 collect particulate impurities from the two filter plates 3 respectively. The collection mechanism also includes two fixed support plates 9 symmetrically fixedly installed on the side of the air inlet box 2 near the exhaust pipe 4. Two symmetrically distributed collection boxes 10 are fixedly installed between the side of the air inlet box 2 away from the exhaust pipe 4 and the inner side of the equipment shell 1. Each collection box 10 is rotatably mounted with a screw 11 between it and the two fixed support plates 9. A sleeve 12 is installed on the outside of the scraper 6. A movable seat 13 that cooperates with the screw 11 is fixedly installed on the outside of the sleeve 12. Two symmetrically distributed optical shafts 14 are fixedly installed between the collection box 10 and the fixed support plate 9, and a sliding opening is provided on the outside of the sleeve 12. The protrusions installed on the outer side of the optical axis 14 cause the screw 11 to rotate, which in turn drives the sleeve 12 to move horizontally along the outer side of the corresponding two optical axes 14. This causes the sleeve 12 to drive the scraper 6 to move along the surface of the filter plate 3, scraping particulate impurities on the filter plate 3 into the collection box 10. Two symmetrically distributed first motors 16 are fixedly installed on the outer side of the equipment housing 1. The output ends of the two first motors 16 are fixedly connected to one end of the two screws 11, so that the first motors 16 can drive the corresponding screws 11 to rotate. Two water storage boxes 8 are fixedly installed at the bottom of the two collection boxes 10. A mounting belt 17 is provided between the inner side of the water storage box 8 and the collection box 10. Multiple equally spaced scraper brushes 18 are fixedly installed on the outer side of the mounting belt 17. Both the water storage box 8 and the collection box 10 have rotatably mounted transmission rods 19 that cooperate with the mounting belt 17 on their inner sides. A second motor 20 is fixedly mounted on the outer side of the collection box 10. The output end of the second motor 20 is fixedly connected to the adjacent transmission rod 19, so that the second motor 20 drives the corresponding transmission rod 19 to rotate. This transmission rod 19, in conjunction with another transmission rod 19, drives the mounting belt 17 to rotate and move, causing the scraper 18 to rotate and move synchronously. This sends the particulate impurities on the scraper 6 into the water storage box 8, where the water in the water storage box 8 collects the particulate impurities. A mounting plate 35 is fixedly mounted on the side of the equipment shell 1 near the exhaust pipe 4. The surface of the mounting plate 35 has multiple mounting holes arranged in a rectangular array. The mounting holes on the mounting plate 35 can be used to mount the particulate impurities. The equipment casing 1 is suspended to improve the ease of installation. A control host 36 is fixedly installed on the outside of the equipment casing 1. The control host 36 is connected to the first motor 16 and the second motor 20 through the equipment casing 1, so that the control host 36 can turn the first motor 16 and the second motor 20 on and off at regular intervals, which facilitates the periodic cleaning of the filter plate 3. A water inlet valve 37 is fixedly installed on the outside of the water storage box 8, and a drain valve 38 is fixedly installed at the bottom of the water storage box 8. Both the water inlet valve 37 and the drain valve 38 extend to the outside of the equipment casing 1, so that the staff can connect the water inlet pipe and the drain pipe to the water inlet valve 37 and the drain valve 38 respectively, which facilitates the filling of water into the water storage box 8 and the discharge of sewage with particulate impurities from the drain valve 38.

[0023] Example 2: Please refer to Figures 2-7 This embodiment further illustrates Example 1. The cleaning mechanism shown in the figure includes two receiving plates 7 symmetrically arranged on both sides of the scraper 6. The receiving plates 7 can concentrate and push out particulate impurities on the scraper 6. The cleaning mechanism also includes a positioning plate 21 fixedly installed on the receiving plate 7 near the side of the sleeve 12. A groove is provided on the outer side of the sleeve 12 for the positioning plate 21 to slide in a limited manner. A plurality of tension springs 22 are fixedly installed between the side of the positioning plate 21 near the sleeve 12 and the inner side of the groove. The inner side of the tension springs 22 is provided with... The first limiting rod 23 is fixedly installed inside the groove of the sleeve box 12. The first limiting rod 23 slides through the positioning plate 21, so that when the scraper 6 is retracted into the sleeve box 12, the rebound force of the tension spring 22 can pull the positioning plate 21 to move along the groove of the sleeve box 12. This causes the two positioning plates 21 to drive the two receiving plates 7 to move closer to each other, scraping off the particulate impurities on the scraper 6. This facilitates the cleaning of the particulate impurities on the two receiving plates 7 by the scraper brush 18, improving the cleaning efficiency of particulate impurities. The inner side of the scraper 6 is flush with the sleeve box 12. A spring 24 is fixedly installed between the inner sides of the air inlet box 2. Pulley rods 25 are rotatably installed on the top and bottom of the scraper 6. Two symmetrically distributed guide rails 26 are fixedly installed on the side of the air inlet box 2 near the casing 12. The pulley rods 25 are slidably installed on the inner side of the guide rails 26, so that when the casing 12 moves, it can drive the two pulley rods 25 on the scraper 6 to move along the inner side of the guide rails 26. The end of the guide rail 26 near the collection box 10 has a stepped structure, and the top and bottom of the casing 12 are provided with openings for limiting the sliding of the pulley rods 25. The elongated groove allows the pulley rod 25 to move along the stepped end of the guide rail 26, thus pulling the scraper 6 along the inner side of the sleeve 12 and compressing the spring 24. The receiving plate 7 can then scrape off the particulate impurities on the scraper 6. A second limiting rod 39 is provided on the inner side of the spring 24. The second limiting rod 39 is fixedly installed on the outer side of the scraper 6 and passes through the sleeve 12, providing support and guidance for the movement of the scraper 6.

[0024] Example 3: Please refer to Figures 3-9This embodiment further illustrates other embodiments. The material receiving mechanism shown in the figure includes a water storage box 8 disposed inside the equipment housing 1. The water storage box 8 can collect and discharge particulate impurities. The material receiving mechanism also includes a driven rod 27 rotatably installed inside the water storage box 8. A synchronous belt 28 is rotatably installed between the transmission rod 19 located inside the water storage box 8 and the driven rod 27, so that when the transmission rod 19 rotates, it can drive the driven rod 27 to rotate synchronously through the synchronous belt 28. A prismatic rod 29 is fixedly installed at one end of the driven rod 27. A sleeve 30 is slidably installed on the outside of the prismatic rod 29. A plurality of centrally symmetrically distributed comb plates 31 are fixedly installed on the outside of the sleeve 30. This allows the prismatic rod 29 to drive the comb plate 31 to rotate via the sleeve 30, scraping away particulate impurities from the scraper 18. A fixing rod 32 is fixedly installed inside the water storage box 8, with the fixing rod 32 and the prismatic rod 29 on the same horizontal line. A collar 33 is rotatably installed at the end of the sleeve 30 near the fixing rod 32. An annular groove for limiting the sliding of the collar 33 is formed at the end of the fixing rod 32 near the prismatic rod 29. An elastic retaining ring 34 is rotatably installed inside the annular groove, with one end of the elastic retaining ring 34 fixedly connected to one end of the collar 33. Multiple centrally symmetrically distributed sliding balls 41 are rotatably installed at the end of the sleeve 30 near the fixing rod 32. One end has multiple centrally symmetrically distributed spherical grooves, each groove being a one-third spherical structure. This allows the sleeve 30 to align the sliding ball 41 with the spherical groove on the fixed rod 32 during rotation. The elastic retaining ring 34 pulls the collar 33 along the annular groove on the fixed rod 32. The collar 33 then pulls the sleeve 30 along the outer side of the prismatic rod 29. As the prismatic rod 29 rotates, the sliding ball 41 on the sleeve 30 slides out of the spherical groove. The sleeve 30, through the collar 33, pulls the elastic retaining ring 34. Thus, as the prismatic rod 29 rotates, the sleeve 30 reciprocates along the outer side of the prismatic rod 29, allowing insertion... The comb plate 31 inside the scraper 18 can shake the scraper 18, improving the cleaning efficiency of the scraper 18. A baffle 40 is fixedly installed on the inner side of the collection box 10. The inner side of the baffle 40 contacts the outer side of the mounting belt 17. When the mounting belt 17 drives the scraper 18 to move upward, the baffle 40 can guide the water dripping from the scraper 18, making it easier for the scraper 18 to discharge more water. A sealing sleeve 15 is fixedly installed at one end of the sleeve 30 near the fixed rod 32. The sealing sleeve 15 is slidably installed on the outer side of the fixed rod 32. When the sleeve 30 moves, it can drive the sealing sleeve 15 to move along the outer side of the fixed rod 32, preventing sewage from entering between the fixed rod 32 and the sleeve 30.

[0025] Working principle: First, air enters the equipment housing 1 through the air inlet pipe 5 and is filtered by two filter plates 3. The filtered air is discharged from the exhaust pipe 4 through the air inlet box 2. Particulate impurities in the air are intercepted on the filter plates 3. Then, the control host 36 starts two first motors 16, which drive the screw 11 to rotate. The screw 11 drives the protrusion on the sleeve 12 to move horizontally along the outer side of the optical axis 14 through the moving seat 13. The sleeve 12 moves from the position of the fixed support plate 9 towards the collection box 10. The sleeve 12 drives the scraper 6 to move along the outer side of the filter plate 3, so that the scraper 6 scrapes off the particulate impurities on the filter plate 3. At the same time, the scraper 6 drives two pulley rods 25 to move along the inner side of the corresponding guide rails 26. When the sleeve box 12 enters the collection box 10, the control host 36 starts the second motor 20. The second motor 20 drives the corresponding transmission rod 19 to rotate, so that the transmission rod 19, in conjunction with another transmission rod 19, drives the mounting belt 17 to rotate and move. The mounting belt 17 drives the scraper 18 to rotate and move synchronously. The scraper 18 carries out a certain amount of water from the water storage box 8 and moves along the outside of the baffle 40, so that the excess water on the scraper 18 can fall back into the water storage box 8, keeping the scraper 18 in a wet state. At the same time, the pulley rod 25 moves to the stepped end of the guide rail 26, so that the pulley rod 25 moves along the stepped section of the guide rail 26. As the sleeve box 12 moves horizontally, the pulley rod 25 can move along the long groove of the sleeve box 12, and the pulley rod 25 can pull the scraper 6. Inside the receiving box 12, the two receiving plates 7 are in contact with the scraper 6. As the scraper 6 moves, the receiving plates 7 can scrape off the particulate impurities on the scraper 6. When the scraper 6 moves away from the receiving plates 7, the spring 22 pulls the positioning plate 21 to move. The positioning plate 21 drives the receiving plates 7 to move, so that the two receiving plates 7 move closer to each other and form a plane. At this time, the wet scraper 18 can scrape the particulate impurities downward along the surface of the two receiving plates 7 and push the particulate impurities into the water storage box 8. At the same time, the scraper 18 entering the water storage box 8 contacts the comb plate 31. The transmission rod 19 drives the driven rod 27 to rotate synchronously through the synchronous belt 28, so that the driven rod 27 drives the sleeve 30 to rotate through the prismatic rod 29. The sleeve 30 drives the comb plate 31 to push out the scraper. The brush removes residual particulate impurities from inside the brush 18. Simultaneously, the sleeve 30 drives the collar 33 and multiple sliding balls 41 to move synchronously. When the sliding balls 41 align with the spherical groove at the end of the fixed rod 32, the elastic retaining ring 34 pulls the collar 33 to move. The collar 33 pulls the sleeve 30 along the outer side of the prismatic rod 29, causing the sliding balls 41 on the sleeve 30 to insert into the spherical groove of the fixed rod 32. When the sliding balls 41 move out of the spherical groove, the reaction force of the sleeve 30 on the sliding balls 41 pushes the sleeve 30 back to its original position along the outer side of the prismatic rod 29. The collar 33 also stretches the elastic retaining ring 34. Thus, as the prismatic rod 29 rotates, the sleeve 30 can reciprocate, causing the comb plate 31 to shake out the particulate impurities inside the brush 18.The scraper 18 facilitates the rapid removal of particulate impurities, which are then discharged through the drain valve 38. Finally, the control unit 36 ​​restarts the first motor 16, causing the screw 11 to drive the housing 12 back to its original position via the moving seat 13. This allows for the next round of cleaning of the filter plate 3, thus completing the cleaning process and achieving both rapid cleaning and particle collection.
