Description

Technical Field

[0001] This invention belongs to the technical field of dust sampling and detection, and more specifically, it relates to an intelligent control type dust sampling device for mining areas. Background Technology

[0002] A dust sampler is a portable device used to collect dust samples from dusty air. Measuring the concentration of dust in the air is necessary not only for safety management but also to provide a scientific basis for researching dust prevention, reduction, and removal measures. Using a sampler to measure dust is a widely recognized method with high accuracy. It is widely used in disease prevention, environmental monitoring, occupational safety, safety supervision, military, scientific research and teaching, metallurgy, petrochemicals, railways, building materials, and other sectors for health monitoring and evaluation. It is specifically used to determine the average dust concentration in the air within production workshops. However, existing dust sampling and detection technologies have the following shortcomings: 1. In the existing technology, when the intelligent control type dust sampling device in the mining area is used to sample dust, the high adhesiveness of the dust makes it easy for the dust to adhere to the wall of the intake sampling tube after long-term use. This results in the inaccurate amount of dust collected by the filter membrane, thus making the data collected each time less accurate.

[0003] 2. A Chinese patent with application number CN202310699952.6 discloses a dust sampler for smoke and dust detection, which includes a sampler body and a collection channel. The outer wall of the sampler body is provided with a cleaning channel, and a cleaning component is provided in the cleaning channel. A switcher is rotatably installed on the outer wall of the sampler body, and multiple detachable sampling tubes are arranged in a circumferential array in the switcher. The sampling tubes can switch and connect between the cleaning channel and the collection channel as the sampler body rotates. The dust sampler for smoke and dust detection provided by this invention can realize the rapid switching of the sampling pipeline and can clean the inner wall of the used sampling pipeline, thereby improving the accuracy of dust sampling. However, this dust sampler only cleans the inner wall of the sampling tube by means of a flexible air bladder, which is not enough to clean the dust adsorbed on the inner wall of the sampling tube. The inner wall of the sampling tube is not cleaned properly, resulting in inaccurate dust retention by the filter membrane and thus insufficient accuracy of the dust collection data each time.

[0004] 3. In the existing technology, the intelligent control type dust sampling device for mining areas requires manual replacement of the filter membrane during use. During the replacement process, the filter membrane is easily contaminated with dust from the environment, which can affect the accuracy of dust concentration measurement.

[0005] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide an intelligent control type dust sampling device for mining areas, in order to achieve a more practical and valuable purpose. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following beneficial effects: This invention discloses an intelligent controllable dust sampling device for mining areas, comprising a switching component and a sampling component. The switching component allows for the switching of six sampling tubes, which, in conjunction with the rotation of a circular plate in the sampling component, move several filter membranes and protective rings sequentially, corresponding to and communicating with the gas pipes. This enables multi-point sampling of the mining area, improving the uniformity and comprehensiveness of the sampling and preventing dust adsorbed on the inner wall of the sampling tubes from affecting the accuracy of dust sampling. The six sampling tubes then move sequentially to one side of a cleaning component, where the cleaning component cleans the inner walls of the six sampling tubes sequentially, maintaining their cleanliness and preventing interference with the collected samples that could lead to errors in the detection results. Finally, the rotating circular plate moves the used protective rings and filter membranes to the side towards the connecting frame. Under the weight of the protective rings and filter membranes, the used filter membranes and protective rings move into the connecting frame, allowing them to be discharged through the connecting frame and outlet for drying and weighing. The mass of collected dust is calculated by the difference between the initial and final weighings. At the same time, by combining the flow rate and sampling time during the sampling process, the concentration of dust contained in the collected air can be calculated, thus enabling faster and more accurate environmental dust sampling.

[0018] This invention discloses an intelligent controllable dust sampling device for mining areas, which includes a cleaning component. The piston rod in the cleaning component moves and rotates, driving a movable cylinder to move and rotate. This movement and rotation of the movable cylinder, in turn, drives a first brush block and a second brush block to move and rotate, achieving a dual cleaning effect on the inner wall of the sampling tube, removing dust adsorbed on the inner wall. Furthermore, the sliding engagement of the first and second brush blocks within an annular frame, along with the positioning of a first annular bladder and the elasticity of the first and second elastic hollow components, allows the first and second brush blocks to move back and forth within the annular frame, further enhancing the cleaning effect on the inner wall of the sampling tube. Next, the movement of the first and second brush blocks within the annular frame compresses the first annular bladder, causing the cleaning solution within the bladder to be sprayed through a first nozzle onto the inner wall of the sampling tube. This dissolves and separates the highly adhesive dust adsorbed on the inner wall of the sampling tube, further improving the cleaning effect. Then, the first annular bladder is compressed to generate elastic force, causing the first and second brush blocks to move away from each other. The first annular bladder elastically resets and draws the cleaning solution from the movable cylinder into the first annular bladder through the first one-way valve, replenishing the cleaning solution in the first annular bladder. Finally, the first and second brush blocks move back and forth within the annular frame, compressing the first and second elastic hollow components, thereby ejecting the air inside the first and second elastic hollow components through the first and second through holes respectively. This disperses the cleaning solution on the inner wall of the sampling tube, increasing the contact area between the cleaning solution and the inner wall of the sampling tube. Furthermore, the movement of the first and second brush blocks compresses or stretches the first and second elastic hollow components, generating elastic force, which causes the first and second brush blocks to move back and forth within the annular frame under the action of the elastic force of the first and second elastic hollow components. So that during the elastic recovery process of the first and second elastic hollow parts, the air inside the first and second elastic hollow parts can be filled through the first and second through holes respectively, so that the first and second elastic hollow parts can be sprayed again to improve the cleaning effect.

[0019] This invention discloses an intelligent controllable dust sampling device for mining areas. The moving and rotating cylinder drives the scraper and wiping blocks to move and rotate, achieving scraping and wiping of the inner wall of the sampling tube, removing and cleaning the dust and solution adsorbed on the inner wall. Furthermore, the scraper and wiping blocks slide within an annular frame, with a second annular bladder for positioning, and the elasticity of the third and fourth elastic hollow components, allowing the scraper and wiping blocks to move back and forth within the annular frame, thus improving the cleaning effect on the inner wall of the sampling tube. Next, the movement of the scraper and wiping blocks within the annular frame compresses the second annular bladder, thereby spraying the cleaning solution inside the second annular bladder through a second nozzle onto the inner wall of the sampling tube, further dissolving and separating the highly adhesive dust adsorbed on the inner wall of the sampling tube. Finally, the scraper and wiping block move back and forth within the annular frame to squeeze the third and fourth elastic hollow parts, thereby ejecting the air inside the third and fourth elastic hollow parts through the third and fourth through holes respectively, so as to further disperse the cleaning solution on the inner wall of the sampling tube and further expand the contact area between the cleaning solution and the inner wall of the sampling tube.

[0036] Preferred options are shown in the appendix. Figure 1 To be continued Figure 10 The sampling assembly includes a housing 25, the upper side of which is fixed to the upper inside of the sampler body 10. A circular plate 71 is rotatably provided inside the housing 25. Several placement slots 30 are arranged in a circular array on the circular plate 71. A protective ring 31 is placed inside each placement slot 30. A filter membrane 32 is fixed inside each protective ring 31. An inlet 16 is provided in the middle of the upper side of the sampler body 10. The inlet 16 is interconnected with the inside of the housing 25. An outlet 34 is provided on one side of the sampler body 10. A connecting frame 33 is provided between the inside of the housing 25 and the outlet 34. The inside of the housing 25 is interconnected with the inside of the air tube 27.

[0037] Preferred options are shown in the appendix. Figure 1 To be continued Figure 10 The lower inner side of the connecting frame 33 has a sloping structure, and a second stepper motor 26 is fixedly installed on one side of the housing 25. The output end of the second stepper motor 26 is fixedly connected to one side of the circular plate 71.

[0038] Specific usage of this invention: The control module 17 in the main body 10 of the sampler has an intelligent control system that can automatically adjust parameters such as sampling flow rate and sampling time to adapt to different mining environments and sampling needs, thereby intelligently controlling the main body 10 of the sampler. Operators can preset programs on the control module 17 through the control panel 11 to achieve automation and precision in the sampling process.

[0039] First, the staff places the sampler body 10 in the mining area. The intelligent control system in the control module 17 starts the air pump 28. The air pump 28 draws air from outside the sampler body 10 through the air inlet pipe 15 and the sampling pipe 21, allowing it to impact, diffuse, and adhere to the surface of the filter membrane 32, thus trapping dust or biological particles in the air on the surface of the filter membrane 32. Next, the air enters the air pump 28 through the air pipe 27, and then enters the air chamber 29 from inside the air pump 28. The intelligent control system in the control module 17 automatically adjusts the start time of the air pump 28 to control the sampling time, and the flow meter 35 detects the air flow rate entering the air chamber 29 to automatically adjust the sampling flow rate.

[0040] Secondly, the used filter membrane 32 is located inside the lower part of the housing 25. The operator places the new protective ring 31 and filter membrane 32 into the corresponding placement slot 30 through the inlet 16. The intelligent control system in the control module 17 starts the second stepper motor 26, which rotates the circular plate 71. This rotation moves the used filter membrane 32 to the outlet 34, whereby, under the weight of the protective ring 31 and filter membrane 32, they move into the connecting frame 33, allowing them to be discharged through the connecting frame 33 and outlet 34. Simultaneously, the rotation of the circular plate 71 moves the new filter membrane 32 and protective ring 31 into the air pipe 27 for dust sampling at other sampling points. The operator then dries and weighs the used filter membrane 32 and protective ring 31, calculating the mass of collected dust by comparing the weights before and after weighing. At the same time, by combining the flow rate and sampling time during the sampling process, the concentration of dust contained in the collected air can be calculated.

[0041] Next, to ensure uniformity and comprehensiveness of the data collection, multiple sampling points are required, resulting in frequent and repeated sampling. The staff places the sampler body 10 at other sampling points. The intelligent control system in the control module 17 starts the first stepper motor 24, which in turn rotates the rotating shaft 18. This rotation of the shaft 18 then rotates the six partitions 19, which in turn rotate the six sampling chambers 20 and sampling tubes 21, causing the six sampling tubes 21 to move sequentially to the upper side. One end of the upper sampling tube 21 is then connected to the air inlet pipe 15, and the other end is connected to the filter membrane 32. This allows the six sampling tubes 21 to sequentially connect to the filter membrane 32, facilitating multi-point sampling of the mining area, improving the uniformity and comprehensiveness of the data collection, and preventing dust adsorbed on the inner wall of the sampling tubes 21 from affecting the accuracy of dust sampling. Simultaneously, the six sampling tubes 21 move sequentially to one side of the cleaning component, allowing the dust-laden sampling tubes 21 to move to the lower part of the fixed cylinder 13.

[0042] Then, the intelligent control system in control module 17 controls the opening of the first solenoid valve 43, allowing air from the air box 29 to enter the cylinder 41 through the connection port 42. The air in the cylinder 41 pushes the piston rod 46 to move. The piston rod 46 moves by engaging with the inner thread of the internal threaded ring 49 at one end, causing it to move and rotate. The movement and rotation of the piston rod 46 drives the movable cylinder 51 to move and rotate, which in turn drives the first brush block 59 and the second brush block 60 to move and rotate, achieving a dual cleaning effect on the inner wall of the sampling tube 21, removing dust adsorbed on the inner wall. Furthermore, the sliding engagement of the first brush block 59 and the second brush block 60 within the annular frame 52, the positioning by the first annular bladder 53, and the elasticity of the first elastic hollow component 63 and the second elastic hollow component 64 allow the first brush block 59 and the second brush block 60 to move back and forth within the annular frame 52, improving the cleaning effect on the inner wall of the sampling tube 21. Next, the first brush block 59 and the second brush block 60 move within the annular frame 52, squeezing the first annular bladder 53. This forces the cleaning solution within the first annular bladder 53 to be sprayed through the first nozzle 57 onto the inner wall of the sampling tube 21, dissolving and separating the highly adhesive dust adsorbed on the inner wall of the sampling tube 21, thereby further improving the cleaning effect on the inner wall of the sampling tube 21. Then, the first annular bladder 53 compresses, generating elasticity, causing the first brush block 59 and the second brush block 60 to move away from each other. The first annular bladder 53 elastically resets, drawing the cleaning solution from the movable cylinder 51 into the first annular bladder 53 through the first one-way valve 55, replenishing the cleaning solution within the first annular bladder 53. Finally, the first brush block 59 and the second brush block 60 move back and forth within the annular frame 52, compressing the first elastic hollow component 63 and the second elastic hollow component 64. This forces the air inside the first elastic hollow component 63 and the second elastic hollow component 64 to be ejected through the first through hole 67 and the second through hole 68, respectively. This disperses the cleaning solution on the inner wall of the sampling tube 21, increasing the contact area between the cleaning solution and the inner wall of the sampling tube 21. Furthermore, the movement of the first brush block 59 and the second brush block 60 compresses or stretches the first elastic hollow component 63 and the second elastic hollow component 64, generating elastic force. Under the elastic force of the first elastic hollow component 63 and the second elastic hollow component 64, both the first brush block 59 and the second brush block 60 can move back and forth within the annular frame 52. So that during the elastic recovery process of the first elastic hollow component 63 and the second elastic hollow component 64, the air inside the first elastic hollow component 63 and the second elastic hollow component 64 can be replenished through the first through hole 67 and the second through hole 68 respectively, so that the first elastic hollow component 63 and the second elastic hollow component 64 can be sprayed again to improve the cleaning effect.

[0043] Simultaneously, the moving and rotating cylinder 51 drives the scraper 61 and wiping block 62 to move and rotate, thereby scraping and wiping the inner wall of the sampling tube 21, removing and cleaning the dust and solution adsorbed on the inner wall of the sampling tube 21. Furthermore, the sliding cooperation of the scraper 61 and wiping block 62 within the annular frame 52, the positioning of the second annular bladder 54, and the elasticity of the third and fourth elastic hollow components 65 and 66 allow the scraper 61 and wiping block 62 to move back and forth within the annular frame 52, improving the cleaning effect on the inner wall of the sampling tube 21. Next, the movement of the scraper 61 and wiping block 62 within the annular frame 52 compresses the second annular bladder 54, causing the cleaning solution inside the second annular bladder 54 to be sprayed through the second nozzle 58 onto the inner wall of the sampling tube 21, further dissolving and separating the highly adhesive dust adsorbed on the inner wall of the sampling tube 21. Then, the second annular bladder 54 is compressed to generate elasticity, causing the scraper 61 and the wiping block 62 to move away from each other. The second annular bladder 54 elastically resets and draws the cleaning solution from the movable cylinder 51 into the second annular bladder 54 through the second one-way valve 56, replenishing the cleaning solution in the second annular bladder 54. Finally, the scraper 61 and the wiping block 62 move back and forth within the annular frame 52, squeezing the third elastic hollow member 65 and the fourth elastic hollow member 66, thereby ejecting the air inside the third elastic hollow member 65 and the fourth elastic hollow member 66 through the third through hole 69 and the fourth through hole 70, respectively, to further disperse the cleaning solution on the inner wall of the sampling tube 21 and further increase the contact area between the cleaning solution and the inner wall of the sampling tube 21. Furthermore, the movement of the scraper block 61 and the wiping block 62 compresses or stretches the third elastic hollow member 65 and the fourth elastic hollow member 66 respectively, generating elastic force. Under the elastic force of the third elastic hollow member 65 and the fourth elastic hollow member 66, both the scraper block 61 and the wiping block 62 can move back and forth within the annular frame 52. This allows the air inside the third elastic hollow member 65 and the fourth elastic hollow member 66 to be replenished through the third through hole 69 and the fourth through hole 70 respectively during the elastic recovery process.

[0044] Finally, when the piston rod 46 moves the movable cylinder 51 above the drain port 23, the impurities inside the sampling tube 21 are discharged through the drain port 23. At this time, after the piston rod 46 moves to one side and stops inside the cylinder 41, the air pressure inside the cylinder 41 continuously increases, thereby increasing the pressure on the pressure regulating valve 48. After the pressure on the pressure regulating valve 48 reaches a certain level, the pressure regulating valve 48 opens, allowing the air inside the cylinder 41 to enter the connecting channel 47 through the pressure regulating valve 48. The air in the connecting channel 47 is sprayed out through several ports 50 to dry the inner wall of the sampling tube 21. Next, the intelligent control system in the control module 17 controls the first solenoid valve 43 to close and the second solenoid valve 45 to open. The air inside the air box 29 enters the cylinder 41 through the connecting pipe 44, thereby causing the piston rod 46 and the movable cylinder 51 to move and reset, so that the movable cylinder 51 can be disengaged from the inside of the sampling tube 21. This allows the clean sampling tube 21 to be moved to the upper side, avoiding interference with the collected samples and preventing errors in the test results. It enables multi-point sampling in the mining area, improving the uniformity and comprehensiveness of the sampling and preventing dust adsorbed on the inner wall of the sampling tube 21 from affecting the accuracy of dust sampling.

[0045] The present invention discloses an intelligent controllable dust sampling device for mining areas, comprising a switching component and a sampling component. The switching component allows six sampling tubes 21 to switch back and forth, coordinating with the rotation of a circular plate 71 in the sampling component. This rotation causes several filter membranes 32 and protective rings 31 to move sequentially, corresponding to and communicating with the air pipes 27. This enables multi-point sampling of the mining area, improving the uniformity and comprehensiveness of the sampling and preventing dust adsorbed on the inner wall of the sampling tubes 21 from affecting the accuracy of dust sampling. Furthermore, the six sampling tubes 21 are sequentially moved to one side of a cleaning component, whereby the cleaning component sequentially cleans the inner walls of the six sampling tubes 21. To maintain the cleanliness of the six sampling tubes 21 and avoid interference with the collected samples that could lead to errors in the test results, the circular plate 71 is rotated to move the used protective ring 31 and filter membrane 32 to one side of the connecting frame 33. Under the weight of the protective ring 31 and filter membrane 32, the used filter membrane 31 and protective ring 31 are moved into the connecting frame 33, allowing them to be discharged through the connecting frame 33 and outlet 34 for drying and weighing. The difference in weight before and after weighing is used to calculate the mass of collected dust. Simultaneously, by combining the flow rate and sampling time during the sampling process, the concentration of dust in the collected air can be calculated, enabling faster and more accurate environmental dust sampling.

[0046] The present invention discloses an intelligent controllable dust sampling device for mining areas, which includes a cleaning component. The piston rod 46 in the cleaning component moves and rotates, causing the movable cylinder 51 to move and rotate. The movable cylinder 51, in turn, moves and rotates the first brush block 59 and the second brush block 60, achieving a dual cleaning effect on the inner wall of the sampling tube 21, removing dust adsorbed on the inner wall. Furthermore, the sliding engagement of the first brush block 59 and the second brush block 60 within the annular frame 52, the positioning by the first annular bladder 53, and the elasticity of the first elastic hollow component 63 and the second elastic hollow component 64 allow the first brush block 59 and the second brush block 60 to move back and forth within the annular frame 52, thereby improving the cleaning effect on the inner wall of the sampling tube 21. Next, the first brush block 59 and the second brush block 60 move within the annular frame 52, squeezing the first annular bladder 53. This forces the cleaning solution within the first annular bladder 53 to be sprayed through the first nozzle 57 onto the inner wall of the sampling tube 21, dissolving and separating the highly adhesive dust adsorbed on the inner wall of the sampling tube 21, thereby further improving the cleaning effect on the inner wall of the sampling tube 21. Then, the first annular bladder 53 compresses, generating elasticity, causing the first brush block 59 and the second brush block 60 to move away from each other. The first annular bladder 53 elastically resets, drawing the cleaning solution from the movable cylinder 51 into the first annular bladder 53 through the first one-way valve 55, replenishing the cleaning solution within the first annular bladder 53. Finally, the first brush block 59 and the second brush block 60 move back and forth within the annular frame 52, compressing the first elastic hollow component 63 and the second elastic hollow component 64. This forces the air inside the first elastic hollow component 63 and the second elastic hollow component 64 to be ejected through the first through hole 67 and the second through hole 68, respectively. This disperses the cleaning solution on the inner wall of the sampling tube 21, increasing the contact area between the cleaning solution and the inner wall of the sampling tube 21. Furthermore, the movement of the first brush block 59 and the second brush block 60 compresses or stretches the first elastic hollow component 63 and the second elastic hollow component 64, generating elastic force. Under the elastic force of the first elastic hollow component 63 and the second elastic hollow component 64, the first brush block 59 and the second brush block 60 move back and forth within the annular frame 52. So that during the elastic recovery process of the first elastic hollow component 63 and the second elastic hollow component 64, the air inside the first elastic hollow component 63 and the second elastic hollow component 64 can be replenished through the first through hole 67 and the second through hole 68 respectively, so that the first elastic hollow component 63 and the second elastic hollow component 64 can be sprayed again to improve the cleaning effect.

[0047] This invention discloses an intelligent controllable dust sampling device for mining areas. The movable cylinder 51 moves and rotates, causing the scraper 61 and wiping block 62 to move and rotate, thus scraping and wiping the inner wall of the sampling tube 21, removing and cleaning the dust and solution adsorbed on the inner wall. Furthermore, the scraper 61 and wiping block 62 slide within the annular frame 52, with the second annular bladder 54 positioned and the third and fourth elastic hollow components 65 and 66 providing elasticity. This allows the scraper 61 and wiping block 62 to move back and forth within the annular frame 52, improving the cleaning effect on the inner wall of the sampling tube 21. Next, the movement of the scraper 61 and wiping block 62 within the annular frame 52 compresses the second annular bladder 54, causing the cleaning solution inside the second annular bladder 54 to be sprayed through the second nozzle 58 onto the inner wall of the sampling tube 21, further dissolving and separating the highly adhesive dust adsorbed on the inner wall of the sampling tube 21. Finally, the scraper 61 and the wiping block 62 move back and forth within the annular frame 52 to squeeze the third elastic hollow component 65 and the fourth elastic hollow component 66, thereby expelling the air inside the third elastic hollow component 65 and the fourth elastic hollow component 66 through the third through hole 69 and the fourth through hole 70, respectively, so as to further disperse the cleaning solution on the inner wall of the sampling tube 21 and further expand the contact area between the cleaning solution and the inner wall of the sampling tube 21.
