Finally, the air in the mine roadway is discharged after being purified by dust removal, so as to realize the circulation of air in the mine roadway.

[0026] The beneficial effects of this invention are:

[0027] 1. This invention achieves multi-level filtration and dust removal of air in mine roadways by setting up curved tubes and adsorption plates, effectively ensuring the dust removal effect of air in the mine. The adjustment component allows for easy adjustment of the dust removal time process in the mine, so as to carry out targeted dust removal according to the air quality in the mine. At the same time, the air conduction speed of the conduction tube can be adjusted.

[0028] 2. This invention sets up a gear ring and a central wheel. When the central wheel rotates, it drives the gear rings on both sides to rotate. When the gear rings rotate, multiple purification components rotate along the axis of the gear rings, thereby agitating the air inside the spray chamber and accelerating the air flow inside the spray chamber. Finally, the air after dust removal flows into the mine roadway to achieve the recycling of waste air.

[0029] 3. This invention features a drive wheel that rotates a directional wheel. The rotation of the directional wheel adjusts the angle of the adsorption head, allowing it to be aligned with the dust source in the mine. This enables the adsorption head to quickly adsorb the dust source and prevents dust from spreading throughout the mine due to prolonged adsorption operations.

[0030] 4. This invention adjusts the height of the mounting plate by swinging the drive plate, and the dust collection cylinder rises and falls synchronously. It controls the angle of the rotating frame on both sides so that the dust collection cylinder can accurately collect dust from the corners and bends in the mine, avoiding excessive dust in the air inside the mine.

Adsorption plates 36 are symmetrically mounted on the left and right sides of the curved tube 35. The electric slider opens to control the rotation of the push-pull wheels 32. The push-pull wheels 32 drive the sliding rods 38 on both sides to move through the moving plates 33, thereby driving the unblocking plates 39 to push the metal dust adsorbed on the adsorption plates 36 into the interior of the adsorption plates 36, so as to facilitate the centralized treatment of the metal dust and dust adsorbed inside the adsorption plates 36. The setting of the curved tube 35 facilitates multi-level filtration and dust removal of the air in the mine roadway, effectively ensuring the dust removal effect of the air in the mine.

[0053] The spray unit 4 includes a fixed plate 41, which is fixedly connected to the spray chamber 22. A central wheel 42 is mounted on the middle of the upper surface of the fixed plate 41 via an electric slider. A bracket 43 is fixedly installed between the two sides of the upper surface of the fixed plate 41 and the two sides of the spray chamber 22.

A connecting pipe 47 is provided around the outer edge of the central component 45. One end of the connecting pipe 47 is connected to the water tank 46 and the other end is fixedly installed with a spray column 48. The clamping plate 44 is used to stably clamp the spray column 48. The connecting pipe 47 is used to transport water from the water tank 46 to the spray column 48. The circulation pipe 492 facilitates the recycling of the water curtain formed by the spray column 48.

[0054] A gear ring 49 is rotatably mounted on the upper surface of the clamping plate 44. A purification component 490 is arranged circumferentially on the upper end face of the gear ring 49 on one side. Limiting components 491 are fixedly installed at the four corners of the spray chamber 22. A circulation pipe 492 is connected to one side of the water tank 46. The circulation pipe 492 passes through and slides within the limiting component 491. The end of the circulation pipe 492 away from the water tank 46 contacts the bottom of the spray chamber 22. When the electric slider is opened, it drives the gear rings 49 on both sides to rotate through the central wheel 42. When the gear ring 49 rotates, multiple purification components 490 rotate along the axis of the gear ring 49, thereby agitating the air inside the spray chamber 22 and accelerating the air flow inside the spray chamber 22. Finally, the air after dust removal flows into the mine roadway to realize the recycling of waste air.

[0055] like Figure 10 , Figure 11 , Figure 12As shown, the suction assembly 5 includes a stretching plate 51, which is telescopically connected to one side of the mounting plate 1. A support plate 52 is fixedly installed on the upper surface of one side of the stretching plate 51. A vacuum cleaner 53 is fixedly installed on one side of the upper surface of the support plate 52. A column frame 54 fixedly connected to the support plate 52 is provided on the front side of the vacuum cleaner 53. A screw 55 is rotatably installed in the column frame 54 via an electric slider. A lifting frame 56 is rotatably installed in the middle of the screw 55. A rotating rod 57 is rotatably installed on one side of the lifting frame 56. The stretching of the stretching plate 51 facilitates the rapid forward and backward adjustment of the support plate 52. The screw 55 is rotated by opening the electric slider. The screw 55 rotates forward or backward, which drives the lifting frame 56 to adjust its height. The vacuum cleaner 53 is used to draw air from the mine into the work box 2 for purification.

[0056] A fixed frame 58 is fixedly installed on one side of the vacuum cleaner 53. A drive wheel 59 is rotatably installed in the middle of the fixed frame 58.

The adsorption head 591, the vacuum cleaner 53 and the work box 2 are connected by a transmission pipe 592. The drive rod is controlled to rotate, which drives the directional wheel 590 to rotate through the drive wheel 59. When the directional wheel 590 rotates, it drives the adsorption head 591 to adjust its angle, so that the adsorption head 591 can be aligned with the dust source in the mine, so that it can quickly adsorb the dust source and avoid the dust in the mine from spreading due to long-term adsorption operation.

[0057] The lifting unit 6 includes a base plate 61. Outer frames 610 are fixedly installed around the upper surface of the base plate 61. A sliding plate 611 is slidably installed inside the outer frame 610. A round shaft is fixedly installed at the bottom of the sliding plate 611. A track 62 is provided on the lower surface of the base plate 61. A I-frame 63 is fixedly installed between multiple outer frames 610. A motor is located in the middle of the I-frame 63. A worm gear 64 is fixedly installed at the motor output end. Worm wheels 65 mesh on both sides of the worm gear 64. A double-acting rod 66 is fixedly installed in the middle of the worm wheels 65.

A rotating frame 68 is symmetrically provided on the front side of the mounting plate 1. The mounting plate 1 is equipped with a dust collection cylinder 69. An electric push rod connected to the rotating frame 68 is located on the front side of the mounting plate 1. The motor drives the worm gear 64 to rotate. When the worm gear 64 rotates, it drives the worm wheels 65 on both sides to rotate, thereby controlling the rotation of the bidirectional rod 66. When the bidirectional rod 66 rotates, it drives the drive plates 67 at both ends to swing, thereby adjusting the height of the mounting plate 1. When the height of the mounting plate 1 is adjusted, the dust collection cylinder 69 rises and falls synchronously. Then, the electric push rod is activated to control the angle of the rotating frame 68 on both sides, so that the dust collection cylinder 69 can accurately vacuum the corners and bends in the mine, avoiding excessive dust in the air in the mine, which would affect the normal breathing of the construction workers in the mine.

[0058] like Figure 6 , Figure 8 As shown, an adsorption chamber 361 is provided in the middle of the adsorption plate 36, and a replacement rack 362 is detachably installed on one side of the adsorption plate 36.

The replacement rack 362 facilitates the cleaning of metal dust and grime adsorbed in the adsorption chamber 361, and the magnetic suction holes 363 facilitate the adsorption of metal dust in the air.

[0059] like Figures 1-14 As shown, another object of the present invention is to provide a method for using a closed dust removal and waste air recycling device in a mine roadway, comprising the following steps:

[0060] S1: Device movement:

[0061] The device is moved to a dusty area in the mine roadway. Then, the height of the device is controlled according to the source of the dust. The motor is turned on to drive the worm gear 64 to rotate. The worm gear 64 drives the bidirectional rod 66 to rotate forward or backward through the worm wheels 65 on both sides. The bidirectional rod 66 controls the lifting of the slide plate 611 through the drive plate 67, thereby controlling the height of the dust suction cylinder 69 of the device, so as to accurately absorb the dust according to the source.

[0062] S2: Enclosed dust removal:

[0063] When the adsorption head 591 is turned on, the air in the mine roadway is sent to the work box 2 through the dust collector 53 and the conveying pipe 592. Then the adsorption plate 36 adsorbs the dust and metal dust in the air, and the air flows in multiple steps in the curved pipe 35.

[0064] S3: Waste air circulation:

[0065] When the air in the mine roadway is treated and flows into the spray chamber 22, the spray column 48 sprays the air to further purify it. The electric slider opens and drives the central wheel 42 to rotate. The central wheel 42 drives the gear rings 49 on both sides to rotate, thereby driving the purification component 490 to rotate, accelerating the air flow inside the spray chamber 22. Finally, the air in the mine roadway is discharged after dust removal and purification, so as to realize the circulation of air in the mine roadway.

[0066] When using this invention, the device is first moved to a dusty area in the mine roadway. The motor is turned on to drive the worm gear 64 to rotate. When the worm gear 64 rotates, it drives the worm wheels 65 on both sides to rotate, thereby controlling the rotation of the bidirectional rod 66. When the bidirectional rod 66 rotates, it drives the drive plates 67 at both ends to swing, thereby adjusting the height of the mounting plate 1. After the height of the mounting plate 1 is adjusted, the dust collection cylinder 69 is raised and lowered simultaneously. Then, the electric push rod is turned on to control the angle of the rotating frame 68 on both sides, so that the dust collection cylinder 69 can accurately collect dust from the corners and bends in the mine, avoiding excessive dust in the air in the mine.

[0067] When air from the mine is drawn into the work box 2, the stretching plate 51 stretches to facilitate quick adjustment of the support plate 52. The electric slider is activated to drive the screw 55 to rotate. The screw 55 rotates forward or backward to drive the lifting frame 56 to adjust its height. The dust collector 53 is activated to draw the air from the mine into the work box 2 for purification. At this time, the curved tube 35 and the adsorption plate 36 perform dust removal on the air in the adsorption chamber 21. The adjusting component 392 adjusts the dust removal time and process in the mine to facilitate targeted dust removal according to the air quality in the mine. At the same time, the air conduction speed of the conduction pipe 390 is adjusted. The curved tube 35 performs multi-level filtration and dust removal on the air in the mine roadway, effectively ensuring the dust removal effect of the air in the mine.

[0068] The water curtain formed by the spray column 48 inside the spray chamber 22 is activated. The connecting pipe 47 collects the water dripping inside the spray chamber 22 and conducts it to the water tank 46. The electric slider opens and drives the gear rings 49 on both sides to rotate through the central wheel 42. When the gear rings 49 rotate, multiple purification components 490 rotate along the axis of the gear rings 49, thereby agitating the air inside the spray chamber 22 and accelerating the air flow inside the spray chamber 22. Finally, the air after dust removal flows into the mine roadway to achieve the recycling of waste air.

[0069] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
