Description

Technical Field

[0001] The present invention relates to the technical field of dust removal devices, in particular to a patrol-type air purification device for underground mines. Background Art

[0002] Currently, underground mining primarily relies on rock drilling and blasting. Drilling, blasting, and loading are the primary sources of dust during tunneling. Furthermore, the increasing mechanization of dead-end tunneling and the use of high-powered tunnel boring machines have led to increased dust concentrations in tunnel air. This excavation process produces a large number of fine, free-flowing mineral and rock particles, known as mine dust.

[0003] Ventilation and dust removal are one of the most effective measures for reducing dust and toxic and hazardous gas concentrations in machine-excavated working areas. Currently, this approach is based on a combination of three approaches: first, employing specific ventilation technologies targeted at dust sources, using airflow to remove dust from the tunnel or using dust control devices to confine high-concentration dust to specific areas; second, utilizing primary dust removal fans to promptly extract dust from the source; and third, utilizing high-pressure spray to force dust particles to settle after attaching to aerosol particles. Dust control technologies are generally categorized by their functional application: ventilation and dust removal, air curtain dust control, spray dust removal, dust collector dust removal, chemical dust suppression, and personal protective equipment. However, current dust removal methods are typically fixed-position dust removal, resulting in slow removal of localized high-concentration dust areas and impacting mining efficiency.

[0035] The present invention provides an underground mine patrol-type air purification device.

[0036] like Figures 1 to 3 The underground mine patrol air purification device shown includes a controller, a first camera 15, a mover 7, a cylinder 1, a first fan 17, an atomizing mechanism 2 and a cylinder 1 arranged on the mover 7. The two openings of the cylinder 1 along the axial direction respectively form an air inlet 11 and an air outlet 12; the filtering mechanism 3, the atomizing mechanism 2 and the first fan 17 are all arranged in the cylinder 1, the first fan 17 is arranged close to the air outlet 12, and the filtering mechanism 3 is arranged on the side of the first fan 17 away from the air outlet 12; the first fan 17 is used to drive the external air to pass through the air inlet 11, the filtering mechanism 3 and Air outlet 12; the atomizing mechanism 2 is connected to the filtering mechanism 3, and the atomizing mechanism 2 is used to input atomized water vapor into the filtering mechanism 3; a first camera 15 is provided on the side of the cylinder 1 away from the movable device 7, and the controller is electrically connected to the first camera 15, the movable device 7, the atomizing mechanism 2 and the first fan 17 respectively, and the controller is used to control the movable device 7 to move along a preset route so that the first camera 15 can obtain a real-time image; the controller is used to determine the dust removal area according to the real-time image, and control the movable device 7 to enter the dust removal area so that the first fan 17 can perform dust removal operations on the dust removal area through the filtering mechanism 3 and the atomizing mechanism 2.

[0037] The mover 7 patrols according to a preset route, and the first camera 15 obtains real-time images during patrolling. The controller determines the dust removal area in the preset route based on the real-time images, and starts the first fan 17 and the atomizing mechanism 2 in the dust removal area, so that the air in the dust removal area contacts the atomized water vapor sprayed by the atomizing mechanism 2 when passing through the filtering mechanism 3, thereby quickly reducing the dust concentration in the dust removal area.

[0038] Specifically, the controller is used to obtain a standard image, and based on the standard image and the real-time image, determine whether there is a blurred area in the real-time image. When there is no blurred area in the real-time image, the controller controls the mover 7 to patrol along the preset route; when there is a blurred area in the real-time image, determine whether the number of blurred areas is greater than or equal to the number of jobs. When the number of blurred areas is greater than or equal to the number of jobs, the controller controls the atomization mechanism 2 and the first fan 17 to start respectively; when the number of blurred areas is less than the number of jobs, the step of the controller controlling the mover 7 to patrol along the preset route is executed.

[0039] Specifically, the standard image is an image obtained after multiple dust removals using an air purification device under the same photographing parameters.

[0040] Among them, when dust removal is performed for the nth time and the n-1th time, when the difference in color protection between the pixels of the image captured after the nth dust removal and the n-1th time is lower than a preset difference, the image captured after the nth dust removal is used as the standard image.

[0041] Specifically, the controller is configured to obtain a preset pixel standard and, based on the pixel standard and the real-time image, determine an abnormal pixel area; and, based on the abnormal pixel area and the standard image, determine a blurred area. The pixel standard is a pixel block of a preset color, such as yellow or gray, that is greater than or equal to a preset area in the real-time image. The abnormal pixel area is determined based on yellow or gray pixel blocks that are greater than or equal to the preset area in the real-time image. The abnormal pixel area is then compared with the corresponding area in the standard image, eliminating interference factors to determine the abnormal area with high dust concentration, and dust removal is then performed on the abnormal area.

[0042] Specifically, when the number of fuzzy areas is less than the number of operations, it is determined whether the sum of the areas of the fuzzy areas is greater than the preset area. When the sum of the areas of the fuzzy areas is greater than or equal to the preset area, the controller controls the atomization mechanism 2 and the first fan 17 to start respectively; when the sum of the areas of the fuzzy areas is less than the preset area, the controller controls the mover 7 to patrol along the preset route.

[0043] Specifically, when the number of fuzzy areas is less than the number of jobs, it is determined whether the color saturation of any fuzzy area is greater than a preset value. When the color saturation of any fuzzy area is greater than or equal to the preset value, the controller controls the atomization mechanism 2 and the first fan 17 to start respectively; when the color saturation of each fuzzy area is less than the preset value, the controller controls the mover 7 to patrol along the preset route.

[0044] Multi-directional dust removal is achieved based on the number of fuzzy areas (i.e. the number of dust points), the area of ​​fuzzy areas (i.e. the size of dust areas) and the color saturation of fuzzy areas (i.e. the concentration of dust) to ensure timely and effective dust removal.

[0045] The filtering mechanism 3 includes a first filter plate 31 and a second filter plate 32, which are arranged parallel and spaced from the air inlet 11 to the air outlet 12. The atomizing mechanism 2 is used to output atomized water vapor between the first filter plate 31 and the second filter plate 32. The arrangement of the first filter plate 31 and the second filter plate 32 achieves multi-level dust removal, ensuring effective dust removal.

[0046] A first slag outlet 13 and a second slag outlet 14 are provided on the side of the cylinder 1 facing the mover 7. A slag storage box 5 is also provided on the side of the mover 7 where the cylinder 1 is located. The slag storage box 5 is connected to the first slag outlet 13 and the second slag outlet 14, respectively. The end of the first slag outlet 13 facing away from the slag storage box 5 is connected to the side of the first filter plate 31 facing away from the second filter plate 32. The end of the second slag outlet 14 facing away from the slag storage box 5 is connected between the second filter plate 32 and the first filter plate 31. The provision of the slag storage box 5, the first slag outlet 13, and the second slag outlet 14 ensures that accumulated dust generated during the dust removal process falls into the slag storage box 5, facilitating routine maintenance by staff.

[0047] A dust removal mechanism 4 is also disposed within the cylinder 1 and is connected to the first filter plate 31 and the second filter plate 32 . The dust removal mechanism 4 is electrically connected to a controller, which controls the dust removal mechanism 4 to remove dust accumulated on the side of the first filter plate 31 facing away from the first fan 17 and on the side of the second filter plate 32 facing away from the first fan 17 . The dust removal mechanism 4 performs routine dust removal on the first filter plate 31 and the second filter plate 32 to ensure effective dust removal.

[0048] Specifically, a second camera 16 is also provided in the cylinder 1, and the second camera 16 is located on the side of the first filter plate 31 away from the second filter plate 32; the second camera 16 is electrically connected to the controller, and the second camera 16 is used to obtain the working image of the first filter plate 31 and send it to the controller, and the controller is used to determine the dust accumulation area of ​​the first filter plate 31 based on the working image; the dust removal mechanism 4 is controlled according to the dust accumulation area, so that the dust removal mechanism 4 removes dust from the first filter plate 31 and the second filter plate 32 respectively according to the dust accumulation area.

[0049] Specifically, the controller is configured to determine the sum of the areas of the first filter plate 31 and the areas of the filter holes in the first filter plate 31 based on the operating image, and then determine the standard number of filter holes based on the sum of the filter hole areas. The controller is also configured to determine the real-time number of filter holes based on the operating image, and then determine the real-time ratio of the real-time number of filter holes to the standard number of filter holes based on the real-time number of filter holes and the standard number of filter holes. The controller then determines whether the real-time ratio is greater than a preset ratio. When the real-time ratio is less than or equal to the preset ratio, the controller activates the dust removal mechanism 4. The dust removal mechanism 4 is controlled based on the number of filter holes in the first filter plate 31 to ensure that the dust removal mechanism 4 maintains the normal operation of the first filter plate 31 and the second filter plate 32.

[0050] The cylinder 1 is provided with two tracks 18, which are arranged parallel to and spaced apart from each other along the axis of the cylinder 1. The two tracks 18 are arranged around the axis of the cylinder 1. The first filter plate 31 is slidably connected to one of the tracks 18 through a slide, and the second filter plate 32 is interactively connected to the other track 18 through a slide. The dust removal mechanism 4 includes a driver and two brushes 41, one of which is arranged on the side of the first filter plate 31 away from the first fan 17 and abuts against the first filter plate 31; the other brush 41 is arranged on the side of the second filter plate 32 away from the first fan 17 and abuts against the first filter plate 31. Abutting the second filter plate 32; a driver drives the first filter plate 31 and the second filter plate 32 respectively; a controller is electrically connected to the driver. When the first fan 17 is started, the controller controls the driver to respectively drive the first filter plate 31 and the second filter plate 32 to rotate along the connected track 18, so that the brush body 41 adjacent to the first filter plate 31 sweeps the dust accumulated on the first filter plate 31 to the first slag outlet 13, and the brush body 41 adjacent to the second filter plate 32 sweeps the dust accumulated on the second filter plate 32 to the second slag outlet 14. By driving the first filter plate 31 and the second filter plate 32 to rotate, the driver enables the two brush bodies 41 to clean the first filter plate 31 and the second filter plate 32, thereby ensuring that the first filter plate 31 and the second filter plate 32 operate normally for a long time.

[0051] The driver includes a first servo motor 42, a first connecting shaft 43 and a second connecting shaft 44. The first connecting shaft 43 is located between the first filter plate 31 and the second filter plate 32, one end of the first connecting shaft 43 is driven to connect to the first filter plate 31, and the other end of the first connecting shaft 43 is driven to connect to the second filter plate 32; the first servo motor 42 is arranged between the second filter plate 32 and the first fan 17, and the output end of the first servo motor 42 is arranged facing the second filter plate 32; the second connecting shaft 43 is located between the second filter plate 32 and the servo motor, the output end of the first servo motor 42 is driven to connect to one end of the second connecting shaft 43, and the other end of the second connecting shaft 43 is driven to connect to the second filter plate 32; the first connecting shaft 43 and the second connecting shaft 43 are coaxially arranged; the controller is electrically connected to the first servo motor 42, and the controller is used to control the first servo motor 42 to drive the second connecting shaft 43 to rotate, so that the second connecting shaft 43 drives the second filter plate 32 to rotate, and then the second filter plate 32 drives the first filter plate 31 to rotate through the first connecting shaft 43.

[0052] Specifically, the first connecting shaft 43 and the second connecting shaft are both parallel to the axial direction of the cylinder 1 .

[0053] The brush body 41 includes a fixing seat (not shown in the figure), a shell (not shown in the figure) and a brush (not shown in the figure). The fixing seat is connected to one end of the shell, and the brush is arranged on one side of the shell. The fixing seat is used to fix the shell in the cylinder 1 so that the brush is arranged facing the first fan 17.

[0054] The atomizing mechanism 2 includes an atomizing nozzle 21, a pump body 22, a connecting pipe 23, and a water tank 24. The water tank 24 is arranged on one side of the cylinder 1 where the mover 7 is arranged. The atomizing nozzle 21 is arranged in the cylinder 1 and is located between the first filter plate 31 and the second filter plate 32. One end of the connecting pipe 23 is connected to the atomizing nozzle 21, and the other end of the connecting pipe 23 is connected to the water tank 24. The pump body 22 is arranged in the connecting pipe 23. A controller is electrically connected to the pump body 22.

The atomized water vapor contacts the air that has been filtered initially, so that the dust in the air that has been filtered initially contacts the atomized water vapor and settles to the lower position between the first filter plate 31 and the second filter plate 32, thereby achieving maximum dust removal and ensuring rapid dust removal of abnormal areas.

The provision of the second fan 6 can help the dust that has come into contact with the atomized water vapor quickly fall into the slag storage box 5, further improving the dust removal effect.

[0056] Specifically, the second fan 6 includes a third filter plate 61, a fan 62, a second servo motor 63 and two rotating shafts 64.

The controller is also configured to control the second servo motor 63 to rotate the third filter plate 61 360 degrees along the rotation axis 64 when a predetermined amount of dust has accumulated on the third filter plate 61. This allows the cleaning brush 65 to scrape the dust accumulated on the third filter plate 61 into the slag storage box 5 during the rotation of the third filter plate 61. The arrangement of the third filter plate 61, the second servo motor 63, and the cleaning brush prevents large amounts of dust from accumulating on the fan 62, reduces the frequency of cleaning the fan 62, and thereby increases the service life and single operating time of the fan 62.
