Description

Technical Field

[0001] The present invention relates to the technical field of mines, and particularly relates to a mobile dust removal device for mines. Background Art

[0002] After the ore is mined in the mine, a transport vehicle is needed to transport the mined ore away. When the ore is conveyed by a conveyor belt and falls into the hopper of the transport vehicle, a large amount of dust will be generated. In order to prevent workers from inhaling a large amount of dust and affecting their physical health, equipment is needed for dust removal. However, since large vehicles such as ore transport trucks are difficult to park at the same position each time and the parking position will change, the dust suction effect in different areas will be different when using fixed equipment. Therefore, a more flexible dust removal device is needed.

[0003] Since the ore falls into the hopper of the transport vehicle and the ore cannot rely on its own rolling to fill the hopper flat at one time, when the amount of ore loaded in a local area of the hopper accumulates to a certain height, the transport vehicle needs to be moved to adjust the position of the hopper. Therefore, dust will be generated near the wheels due to the movement of the transport vehicle. Secondly, when the ore is transported onto the transport vehicle, after the dropped ore collides with the hopper of the transport vehicle or the ore collides with the ore, flying crushed stone pieces and small stones will be generated. The crushed stone pieces and small stones will splash into the dust suction port of the dust removal device. In the prior art, a filter screen is arranged at the position of the dust suction port to block the crushed stone pieces and small stones, but there will always be crushed stone pieces and small stones with appropriate sizes stuck in the grid gaps of the filter screen, causing the filter screen to be blocked and affecting the dust suction effect.

In the prior art, a filter screen will be set at the position of the dust suction port to block the gravel pieces and small stones, but the gravel pieces and small stones will still get stuck in the mesh gaps of the filter screen, affecting the dust suction effect. By arranging the first baffle on the inner surface of the dust collection frame to block at the third air pipe, the flying gravel pieces and small stones need to first pass through the gap between the dust collection frame and the first baffle, and collide multiple times in the gap, quickly consuming the kinetic energy of the gravel pieces and small stones, greatly reducing the probability that the gravel pieces and small stones directly fly into the third air pipe. The gravel pieces and small stones that have lost kinetic energy after multiple collisions will directly slide out of the gap from the gap.

[0016] The present invention solves the problem that because the ore falls into the hopper of the transport vehicle, the ore cannot rely on its own rolling to fill the hopper at one time. Therefore, when the amount of ore loaded on one side of the hopper accumulates to a certain height, the transport vehicle needs to be moved to adjust the position of the hopper. Therefore, dust will be generated near the wheels due to the movement of the transport vehicle. By spraying water mist through the first nozzle, the dust in the air is preliminarily settled, and the fan is started to absorb the dust that has not been combined with the water mist for settlement and removal.

[0017] The present invention solves the problem that after water mist and dust are combined with each other, they adhere to the rear wall surface of the dust collection frame or the front wall surface of the first baffle frame, and finally the gap between the first baffle frame and the dust collection frame is blocked; the adhered water mist and dust are scraped off by the second moving block and the first motor driving the first scraping blade.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby.

It also includes a dust collection frame 1012, a connecting block 108, a first blocking frame 106, and a support assembly; each third air duct 105 is connected to a dust collection frame 1012; a support assembly for supporting the dust collection frame 1012 is connected to the housing 1; at least two connecting blocks 108 are fixedly connected to the middle of the rear surface of each dust collection frame 1012; a first blocking frame 106 is fixedly connected by a plurality of connecting blocks 108.

[0022] The first blocking frame 106 and the dust collection frame 1012 are in a horn shape, which can allow the dust to be inhaled smoothly along the gap between the first blocking frame 106 and the dust collection frame 1012.

[0023] The support assembly includes a first guide rail 302, a first moving block 303, a hinged plate 304, a first push rod 305, and a second push rod 306; the housing 1 is bolted with a first guide rail 302; two first moving blocks 303 are slidably connected to the first guide rail 302, and the two first moving blocks 303 are respectively located on the left and right sides of the housing 1; each first moving block 303 is hinged with a hinged plate 304; a locking torsion block for locking the hinged plate 304 is installed on each first moving block 303; a first push rod 305 is fixedly connected to each hinged plate 304; a locking torsion block for locking its telescopic part is installed on each first push rod 305; the telescopic part of each first push rod 305 is rotatably connected to a second push rod 306; a locking torsion block for preventing relative rotation with the first push rod 305 is installed on each second push rod 306; the telescopic part of each second push rod 306 is in a damping rotational connection with the front side of the adjacent dust collection frame 1012; a locking torsion block for locking its telescopic part is installed on each second push rod 306.

[0024] It further includes a second guide rail 107, a second moving block 1013, a first wiper 1014, a first water pipe 1011, a first motor 109 and a first nozzle 1010; a first water pipe 1011 is fixedly connected to the edge of each dust collection frame 1012 through a plurality of fixing rings 508; a plurality of first nozzles 1010 are communicated with each first water pipe 1011; second guide rails 107 are bolted to the four curved corners of the rear side surface of the dust collection frame 1012; each second guide rail 107 is slidably connected with a second moving block 1013; two first motors 109 are bolted to each second moving block 1013, one of the first motors 109 is horizontally arranged, the other is vertically arranged, and the rotating parts of the first motors 109 arranged in the same direction on two adjacent second moving blocks 1013 face each other, and all the first motors 109 are received in a protective shell; an elastic first wiper 1014 is fixedly connected between two adjacent first motors 109 facing each other; brush hairs in contact with the second guide rail 107 are bonded to both ends of each second moving block 1013 for cleaning dust particles attached to the second guide rail 107.

[0025] First, move the mobile dust removal equipment for mines to the side of the transport vehicle being loaded. Adjust the position of the first moving block 303 on the first guide rail 302, adjust the telescopic lengths of the telescopic parts of the first push rod 305 and the second push rod 306, and adjust the angle of rotation of the second push rod 306 on the first push rod 305. After adjustment, turn each locking knob so that the locking knob is tightened, and fix each position through friction, so as to support the dust collection frame 1012 and align it with the position where dust suction is required. Subsequently, start the mobile dust removal equipment for mines. During the loading process, after the dropped ore collides with the hopper of the transport vehicle or between the ores, flying gravel pieces and small stones will be generated and fall into the dust suction port. In the prior art, a filter screen is set at the position of the dust suction port to block the gravel pieces and small stones, but the gravel pieces and small stones will still get stuck in the mesh gaps of the filter screen, affecting the dust suction effect. Therefore, in the present invention, a first baffle frame 106 is arranged on the inner surface of the dust collection frame 1012 to block at the third air duct 105, so that the flying gravel pieces and small stones need to first pass through the gap between the dust collection frame 1012 and the first baffle frame 106, and multiple collisions will occur in the gap, quickly consuming the kinetic energy of the gravel pieces and small stones, greatly reducing the probability of the gravel pieces and small stones directly flying into the third air duct 105. The gravel pieces and small stones that have lost kinetic energy after multiple collisions will directly slide out of the gap from the gap. The first baffle frame 106 replaces the original filter screen, which not only prevents gravel pieces and small stones from entering the third air duct 105, but also does not have the problem that the filter screen will still get stuck in the mesh and hinder the normal dust suction work, and there is no need for manual cleaning at regular intervals; the normal flat dust collection frame 1012 and the first baffle frame 106 can achieve the above effects. However, during the dust suction process of the flat dust collection frame 1012 and the first baffle frame 106, the air flow enters the gap vertically with respect to the dust collection frame 1012, which causes the air flow to first vertically impact the rear surface of the dust collection frame 1012 and then flow to the third air duct 105. This will result in a large resistance to the air flow, and thus the dust suction effect is not good. In the present invention, the dust collection frame 1012 and the first baffle frame 106 are set in a trumpet shape, and the air flow does not vertically impact the rear surface of the dust collection frame 1012. In this way, the air flow can be guided by the rear surface of the dust collection frame 1012 and flow towards the third air duct 105, and the resistance to the air flow is small, and the dust suction effect is better.

[0026] When dust removal is required, it is connected to the water inlet provided at the front of the first water pipe 1011 through an external water pump, and the external water pump is started to make the first nozzle 1010 spray water mist to preliminarily settle the dust in the air. During this process, the fan 4 is started, and the dust that has not been settled by combining with the water mist will be sucked into the gap between the first baffle 106 and the dust collection frame 1012. At this time, some water mist will also be sucked into the gap between the first baffle 106 and the dust collection frame 1012 by the fan 4. At this time, the phenomenon that the two combine with each other and adhere to the rear side of the dust collection frame 1012 or the front side of the first baffle 106 will occur, resulting in the combined substance not being able to be further carried away by the suction air flow, and the caked dust adhering to these two places will have a higher probability of contacting the floating and attracted water mist and dust, further blocking and intercepting them, resulting in a further increase in the volume of the caked dust and a further increase in the growth rate, thus forming a vicious cycle, and finally causing the gap between the first baffle 106 and the dust collection frame 1012 to be blocked. Therefore, during regular shutdown maintenance, first let the equipment run idle to suck dust-free air to dry the adhering dust through the air flow, and then drive the second moving block 1013 to move towards the center of the dust collection frame 1012 through the second guide rail 107 on the dust collection frame 1012. At the same time, the first motor 109 drives the first scraper 1014 to rotate, and the first scraper 1014 contacts the front side of the first baffle 106 and the rear side of the dust collection frame 1012 at the same time. Driven by the second moving block 1013 and the first motor 109, the first scraper 1014 fully scrapes the caked dust adhering to the rear surface of the dust collection frame 1012 and the front surface of the first baffle 106. During the process of the second moving block 1013 moving towards the center of the dust collection frame 1012, because the distance between two adjacent second guide rails 107 becomes smaller and smaller, the first scraper 1014 will contract. After reaching the limit distance, it will move back to its original position. During the reset process, the distance between two adjacent second guide rails 107 becomes larger and larger, causing the first scraper 1014 to expand, and through the deformation of the first scraper 1014, the dust adhering to the first scraper 1014 falls off, achieving a self-cleaning effect. By reciprocating in this way, the dust adhering to the rear surface of the dust collection frame 1012 and the front surface of the first baffle 106 can be scraped off, preventing the caked dust from blocking the gap for air flow and affecting the normal dust suction operation; in the maintenance state, the dust and dust adhering to the second guide rail 107 are also dry. During the movement of the second moving block 1013, the bristles bonded to both ends of the second moving block 1013 can shovel these dry dust from the second guide rail 107 to maintain the second guide rail 107.

[0027] Embodiment 2 On the basis of Embodiment 1, as Figure 3 and Figure 4As shown in the figure, it further includes a scraping component; the scraping component includes a fourth air duct 103, a first connecting plate 401, a second motor 402, a cleaning plate 403 and a first filter screen 404; there are two fourth air ducts 103 provided inside the housing 1, and each fourth air duct 103 is communicated with the adjacent second air duct 102; a first connecting plate 401 is fixedly connected in each first air duct 101; a second motor 402 is bolted to each first connecting plate 401; three cleaning plates 403 are fixedly connected to the rotating part of each second motor 402; a first filter screen 404 is welded in each first air duct 101; the cleaning plate 403 is in contact with the first filter screen 404.

[0028] The cleaning plate 403 is arranged in an inclined state, guiding the scraped dust towards the fourth air duct 103, avoiding the residue of dust.

[0029] For the existing dust suction device, the dust filtering components need to be maintained regularly. Usually, the dust filtering components are removed from the dust suction device for dust removal maintenance. The disassembly and assembly process is very troublesome, and the disassembly and assembly process will cause vibration to the dust filtering components, resulting in the dust on the dust filtering components falling off and rising. By rotating the second motor 402 to drive the cleaning plate 403 to rotate, the dust on the first filter screen 404 is scraped off, and the dust will be pushed into the fourth air duct 103 for discharge under the guidance of the inclined cleaning plate 403, avoiding the problem of dust accumulation and blocking of the first filter screen 404, so as to achieve the effect of cleaning and maintaining the first filter screen 404 without disassembling the equipment, and the dust will not disperse into the external environment.

[0030] Embodiment 3 On the basis of Embodiment 2, as Figure 3-Figure 4 and Figure 7 shown in the figure, it further includes an anti-dust-raising component; the anti-dust-raising component includes a spiral chute 503, a third connecting plate 502 and a collection bucket 3; a collection bucket 3 is provided at the bottom inside the housing 1; a spiral chute 503 is provided inside each fourth air duct 103, and each spiral chute 503 is located above the collection bucket 3. A blocking disc that can automatically lift is slidably connected to each spiral chute 503. The blocking disc is located at the junction of the fourth air duct 103 and the second air duct 102. When it is not necessary to discharge the dust on the first filter screen 404, the blocking disc will block the upper part of the fourth air duct 103. When it is necessary to discharge the dust on the first filter screen 404, the blocking disc will move upward, so that the dust falls onto the spiral chute 503; the top of the spiral chute 503 penetrates through the adjacent second air duct 102; two third connecting plates 502 are fixedly connected inside the collection bucket 3, and each spiral chute 503 is rotatably connected to the respective third connecting plate 502 below it.

[0031] The anti-dust assembly also includes a connecting frame 301 and a third motor 501; two connecting frames 301 are welded on the top rear side of the shell 1; each connecting frame 301 is bolted to the third motor 501, and the top of each spiral slide 503 is fixedly connected to the rotating part of the third motor 501 above it.

[0032] It also includes a water spray assembly; the water spray assembly includes a second filter 504, a pump 505, a second water pipe 506, a second nozzle 507 and a fixing ring 508; three filter slots distributed up and down are opened on the opposite sides of the upper parts of the two fourth air ducts 103, and each filter slot is equipped with a second filter 504; the upper part of the water bucket 2 is bolted with a pump 505; the water outlet of the pump 505 is connected to the second water pipe 506, and the second water pipe 506 has two water outlets; each water outlet of the second water pipe 506 is bolted and connected to a second nozzle 507, and the two second nozzles 507 are respectively facing the second filter 504 in the corresponding filter slot; a plurality of symmetrically arranged fixing rings 508 are welded inside the shell 1; the second water pipe 506 passes through adjacent fixing rings 508. It also includes a water bucket 2 and a second baffle 104; the water bucket 2 is welded to the bottom of the shell 1, and the collecting bucket 3 is located inside the water bucket 2; the bottoms of the two fourth air ducts 103 are commonly fixed with the second baffle 104, and the bottom edge of the second baffle 104 is located above the water bucket 2. When the second nozzle 507 sprays water mist at the middle of the fourth air duct 103, water droplets will condense on the outer wall of the fourth air duct 103, and the water droplets will flow down along the curved outer wall of the second baffle 104 to the water bucket 2 for collection, thereby avoiding the waste of water resources.

[0033] After the dust is scraped off the first filter screen 404 by the scraping component, if the dust is directly allowed to fall along the fourth air duct 103, the dry dust will inevitably generate dust in the process of falling. If no treatment is performed, it is necessary to wait for the dust to settle naturally before starting the dust extraction work again. Otherwise, it is very easy to draw the dust back onto the first filter screen 404. The present invention allows the dust to be scraped off the first filter screen 404, and then the blocking disk moves up to open the fourth air duct 103, allowing the dust to fall onto the spiral slide 503 and slide downward along the spiral slide 503 to reduce the falling speed of the dust, thereby avoiding the problem of dust directly falling and scattering. Even if the problem of dust scattering occurs during the sliding process, the flying dust can be isolated in a limited space through the spiral structure of the spiral slide 503 to prevent the dust from spreading over a large area.

[0034] When the dust automatically slides down and is discharged, there is a problem that the dust stays on the spiral slide 503 and cannot slide through the spiral slide 503 entirely by relying on its own falling power. Therefore, it is necessary to rely on the third motor 501. The third motor 501 is started regularly to drive the spiral slide 503 to rotate slowly to discharge the dust remaining on the spiral slide 503.

[0035] Because the dust discharged from the spiral slide 503 needs to be collected by the collecting bucket 3, and the storage space of the collecting bucket 3 needs to be fully utilized, the bottom outlet of the spiral slide 503 must be suspended above the collecting bucket 3, and will not be attached to the inner bottom of the collecting bucket 3. This causes the dust to fall after being discharged from the bottom outlet of the spiral slide 503. Although the falling distance is not long, it still causes dust to be raised, resulting in the dust flying and spreading to the second baffle frame 104 and the surrounding area of ​​the bucket 2. By starting the pump 505, the water in the water bucket 2 is passed into the second water pipe 506 and sprayed out from the two second nozzles 507. The sprayed water mist is sprayed into the fourth air duct 103 through the filter groove provided on the fourth air duct 103. After the water mist comes into contact with the dust on the spiral slide 503, the dust is wetted. In this way, even if the dust falls, it will not fly. Then it flows downward along the spiral slide 503 to the collection bucket 3. The dust is wetted to avoid the dust from falling into the collection bucket 3 after the dust leaves the spiral slide 503 and causing dust to be raised.

[0036] When the second nozzle 507 sprays toward the filter slot of the fourth air duct 103, water mist will be sprayed on the outer surface of the fourth air duct 103, flow along the outer surface of the fourth air duct 103 to the edge of the second baffle 104, and then fall into the water bucket 2 for reuse, avoiding waste of water resources.

[0037] When the dust in the collection barrel 3 has completed the last maintenance work of the first filter 404 and has reached the point where it must be emptied, the wet dust will clump together and cover the dry dust collected previously. Some water mist will also gather into a water flow and flow into the collection barrel 3 from the spiral slide 503 to moisten the dry ash on the surface, thereby preventing the dust in the barrel from being blown up due to manual action when the barrel is taken away for emptying. At this point, the dust removal work is completed.

[0038] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
