Description

Technical Field

[0001] The invention relates to the technical field of mine safety, in particular to a pneumatic automatic slag removal, dust removal and anti-spray hole device. Background Art

[0002] The pneumatic automatic slag discharge, dust removal and anti-spray hole device is a device designed specifically for industrial environments such as coal mines. It aims to improve work safety and reduce environmental pollution through automatic slag discharge and dust removal functions. The pneumatic automatic slag discharge, dust removal and anti-spray hole device mainly uses compressed air as a power source and realizes automatic slag discharge and dust removal functions through a specific mechanical structure and control system. The pneumatic automatic slag discharge, dust removal and anti-spray hole device is an efficient and practical industrial equipment, which is of great significance to improving the safety and environmental protection of industrial environments such as coal mines.

[0003] When drilling gas extraction holes, a large amount of coal slag will be generated and needs to be cleaned in time. In the past, it was cleaned manually, which was time-consuming and labor-intensive. Now, a pneumatic automatic slag discharge device is used, which is timely, fast, time-saving and labor-saving. When drilling gas extraction holes, a large amount of gas will gush out, causing the spray hole and gas to exceed the limit. The pneumatic automatic slag discharge, dust removal and spray hole prevention device has significant advantages in industrial environments such as coal mines, but it also has some disadvantages. Although the device has broad application prospects in industrial environments such as coal mines, its applicable environment is still subject to certain restrictions. For example, under extremely harsh working conditions, the performance of the device may be affected. Some pneumatic automatic slag removal, dust removal and anti-blowout hole devices may be equipped with a gas-water separator to separate and process the gas and moisture generated during the drilling process. However, the gas-water separator is usually large in size and will take up more space. In addition, the filter will be clogged during long-term use of the device. In application scenarios such as coal mines, the presence of a mixture of coal dust and gas may increase the risk of filter clogging. The tiny particles of coal dust and impurities in the gas may become factors that clog the filter. The mixture of water vapor and coal dust will make the filter easier to adhere to the filter, making it more troublesome to clean the filter. Summary of the invention

[0016] Beneficial effects of the present invention:

[0017] (1) The pneumatic automatic slag discharge and dust removal anti-spray hole device described in the present invention has a first air bag installed on the outside of the dust collecting pipe. When in use, the air bag will be inflated to seal the hole, thereby preventing a large amount of gas from gushing out when the gas extraction hole is opened, causing the spray hole and gas to exceed the limit. This device adopts a multi-layer composite anti-spray cover with a matching hole sealing sleeve and a slag discharge box shell to form an enclosed space, so that the gas is tightly locked in this device. After the dust-containing gas is extinguished inside the slag discharge box, it is connected to the gas negative pressure pipeline through the gas extraction pipe on the top of the slag discharge box to achieve harmless treatment of the gas.

[0018] (2) The pneumatic automatic slag removal, dust removal and anti-spray hole device described in the present invention adopts a structure that is set up so that when the pneumatic hydraulic cylinder moves toward one end close to the partition, it will drive the wavy filter to unfold. The unfolding of the wavy filter will drive the dust on its surface to fall off. At the same time, it will also drive the first movable plate and the second movable plate to move in the direction away from the filter to compress the second air bag. The second air bag is compressed and the gas inside it enters the interior of the nozzle. The gas enters the interior of the nozzle and sprays high-pressure gas from the lower end to blow the filter from top to bottom. The high-pressure gas blowing the filter from top to bottom will further clean the filter and clean the dust attached to the bottom of the filter to the upper end of the support plate.

[0019] (3) The pneumatic automatic slag removal, dust removal and anti-spray hole device described in the present invention has a filter screen in a folded wave shape, the edge of which is made of rubber material and fits tightly with the shell. The upper end of the filter screen is a layer of sponge. The layer of sponge provided on the upper end of the filter screen can further improve the filtering effect. At the same time, the layer of sponge provided on the upper end of the filter screen can also absorb water vapor in the gas. When the roller moves downward to reset, the first movable plate and the second movable plate will squeeze the filter screen inward under the action of the torsion spring. The filter screen will be squeezed and folded along its wave shape. The filter screen will squeeze the sponge on its upper end. At the same time, the filter screen can also increase the contact thickness between the gas and the filter, thereby improving the filtering effect.

[0020] (4) The pneumatic automatic slag discharge, dust removal and anti-spray hole device described in the present invention has a structure that, when the pneumatic hydraulic cylinder moves toward one end close to the partition, it also drives the other end close to the pneumatic hydraulic cylinder to move, thereby driving the sliding plate to move toward one end. The movement of the sliding plate toward one end drives the second hollow groove to coincide with the sewage outlet, so that the inside of the shell is connected to the outside world, which is convenient for the subsequent discharge of coal and impurity particles from the device. When the sliding plate blocks the sewage outlet, the gas inside the shell can be sealed to prevent leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Preferably, the discharge mechanism 900 includes an air motor 901, the lower end of the air motor 901 is fixedly connected to the base 100, one end of the air motor 901 is fixedly connected to a first rotating shaft 902, the surface of the first rotating shaft 902 is fixedly connected to a first spur gear 903, the lower end of the first spur gear 903 is meshed with a second spur gear 904, the center of the second spur gear 904 is fixedly connected to a second rotating shaft 905, one end of the second rotating shaft 905 is rotatably connected to the housing 200, and the surface of the second rotating shaft 905 is connected to the partition 204. Rotationally connected, one end of the second rotating shaft 905 is fixedly connected with a spiral rod 906, and the spiral rod 906 is infinitely close to the arc-shaped groove at the bottom end of the support plate 203 but does not fit; at this time, the pneumatic motor 901 is started to rotate, and the rotation of the pneumatic motor 901 will drive the first rotating shaft 902 to rotate, and the rotation of the first rotating shaft 902 will drive the first spur gear 903 to rotate, and the rotation of the first spur gear 903 will drive the second spur gear 904 to rotate. The diameter of the first spur gear 903 is smaller than the diameter of the second spur gear 904. Therefore, the pneumatic motor 901 can reduce the speed and increase the torque through the first spur gear 903 and the second spur gear 904, and the rotation of the second spur gear 904 will drive the second rotating shaft 905 to rotate, and the rotation of the second rotating shaft 905 will drive the spiral rod 906 to rotate, and the spiral rod The rotation of 906 will discharge the particles and coal in the groove at the bottom end of the support plate 203. The first spur gear 903 and the second spur gear 904 can reduce the rotation speed and increase the torque, so that the driving force of the spiral rod 906 can be large and the coal slag can be better discharged from the equipment. When the spiral rod 906 pushes the coal slag at a slower speed, the impact force on the coal slag particles during the transportation process is smaller, which reduces the repeated crushing of the coal slag, which helps to maintain the integrity of the coal slag particles and reduce the generation of fine-grained coal slag, thereby improving the utilization value of the coal slag. When the spiral rod 906 pushes the coal slag at a slower speed, the resistance and impact force it encounters are also reduced accordingly, which helps to reduce the wear of key components such as the spiral rod and bearings. Under long-term operation, this can extend the service life of the equipment and reduce maintenance costs.

[0045] Working principle: When the present invention is used, the dust collecting tube 401 is first placed into the orifice, and the rotation of the nut 502 drives the screw 501 to rotate, and the rotation of the screw 501 drives the piston 504 to move downward, and the downward movement of the piston 504 will fill the air inside the first sleeve 503 into the first air bag 506 through the first connecting pipe 505, and the air will expand when it is filled into the first air bag 506 through the first connecting pipe 505 to seal the orifice, and the gas filtered inside the housing 200 is sucked out through an external device at the gas extraction port; By installing a first air bag 506 on the outside of the dust collecting pipe 401, the first air bag 506 will be inflated to seal the hole when in use, preventing a large amount of gas from gushing out when drilling the gas extraction hole, causing the spray hole and gas to exceed the limit. By using the auger hose 1000 as a conveying pipeline, the coal slag, coal powder and other materials generated during the drilling process can be effectively transported from the drilling site to the designated processing or collection location. This transportation method avoids the accumulation of materials near the drilling hole, reduces the occurrence of drill holding, and improves the efficiency of drilling construction.

[0046] The motor in the dust hood 400 drives the fan blades to generate negative pressure suction, thereby drawing the gas and dust in the hole into the first connecting hose 300. The gas in the first connecting hose 300 will enter the bottom end of the outer shell 200. The gas in the bottom end of the outer shell 200 will be filtered by the filter 603. The gas filtered by the filter 603 passes through the first hollow groove 6091 and is discharged from the gas extraction port 205.

[0047] At this time, the pneumatic hydraulic cylinder 701 is started to move toward one end close to the partition 204, and the pneumatic hydraulic cylinder 701 moves toward one end, and the first sliding block 702 moves toward one end, which drives the rotating pin 703 to move toward one end, and the rotating pin 703 moves toward one end, which slides inside the guide groove 706 to make the second sliding block 705 move upward, and the second sliding block 705 moves upward, which drives the fixed block 707 to move upward, and the fixed block 707 moves upward, which drives the roller 708 to move upward, and the roller 708 moves upward, which drives the first movable plate 602 and the second movable plate 604 to move away from the filter screen 603; the filter screen 603 is folded in a wave shape, and the edge is made of rubber material and the shell 200 The filter 603 is tightly fitted, and there is a layer of sponge on the upper end of the filter 603. Arranging a layer of sponge on the upper end of the filter 603 can further improve the filtering effect. At the same time, the layer of sponge arranged on the upper end of the filter 603 can also absorb water vapor in the gas. When the roller 708 moves downward to reset, the first movable plate 602 and the second movable plate 604 will squeeze the filter 603 inwardly under the action of the torsion spring. The filter 603 is squeezed and folded along its wavy shape. The filter 603 will squeeze the sponge on its upper end. At the same time, the filter 603 can also increase the contact thickness between the gas and the filter, thereby improving the filtering effect. The movement of the first movable plate 602 and the second movable plate 604 away from the filter 603 will drive the filter to form a wavy shape. The filter 603 is unfolded, and the wavy filter 603 unfolds, which drives the dust on its surface to fall off. When the first movable plate 602 and the second movable plate 604 move in the direction away from the filter 603, the second airbag 606 is compressed, and the gas inside the second airbag 606 is discharged from the second connecting hose 607. The second rotating rod 605 is hollow, and the gas is discharged from the second connecting hose 607 and passes through the second rotating rod 605 and the second connecting pipe 608 into the nozzle 609. The gas enters the nozzle 609 and sprays high-pressure gas from the lower end to blow the filter 603 from top to bottom. The high-pressure gas blows the filter 603 from top to bottom, which further cleans the filter 603 and cleans the dust attached to its bottom to the support plate 20. 3; the structure is set up so that when the pneumatic hydraulic cylinder 701 moves toward the end close to the partition 204, the wavy filter 603 will be driven to unfold, and the wavy filter 603 will cause the dust on its surface to fall off, and at the same time, the first movable plate 602 and the second movable plate 604 will be driven to move away from the filter 603 to compress the second airbag 606, and the second airbag 606 is compressed and the gas inside it enters the nozzle 609, and the gas enters the nozzle 609 and sprays high-pressure gas from the lower end to blow the filter 603 from top to bottom. The high-pressure gas blows the filter 603 from top to bottom, which will further clean the filter 603 and clean the dust attached to the bottom of the filter to the upper end of the support plate 203;The filter 603 is arranged in a folded wave shape, the edge is made of rubber material and fits tightly with the housing 200, and the upper end of the filter 603 is a layer of sponge. The layer of sponge arranged on the upper end of the filter 603 can further improve the filtering effect. At the same time, the layer of sponge arranged on the upper end of the filter 603 can also absorb water vapor in the gas. When the roller 708 moves downward to reset, the first movable plate 602 and the second movable plate 604 will squeeze the filter 603 inward under the action of the torsion spring. The filter 603 will be squeezed and folded along its wave shape. The filter 603 will squeeze the sponge on its upper end. At the same time, the filter 603 can also increase the contact thickness between the gas and the filter, thereby improving the filtering effect. ;

[0048] When the pneumatic hydraulic cylinder 701 moves toward the end close to the partition 204, it will also drive the wire rope 801 to move toward the end close to the pneumatic hydraulic cylinder 701. The movement of the wire rope 801 toward the end close to the pneumatic hydraulic cylinder 701 will drive the sliding plate 803 to move toward the end close to the pneumatic hydraulic cylinder 701. The end of the sliding plate 803 close to the pneumatic hydraulic cylinder 701 will compress the spring 804. When cleaning the filter screen 603, it will also drive the second hollow groove 8031 ​​to overlap with the sewage outlet 201. In this way, the inside of the housing 200 is connected with the outside world, which is convenient for subsequent cleaning. The coal mine and impurity particles of the discharge device; through the structure set up, when the pneumatic hydraulic cylinder 701 moves toward the end close to the partition 204, it will also drive the end close to the pneumatic hydraulic cylinder 701 to move, and then drive the sliding plate 803 to move to one end; the movement of the sliding plate 803 to one end will drive the second hollow groove 8031 ​​to coincide with the sewage outlet 201, so that the shell 200 is connected with the outside world, which is convenient for the subsequent discharge of coal mines and impurity particles of the device, and the sewage outlet 201 is blocked by the sliding plate 803, so that the gas inside the shell 200 can be sealed to prevent leakage.

[0049] At this time, the pneumatic motor 901 is started to rotate. The rotation of the pneumatic motor 901 will drive the first rotating shaft 902 to rotate. The rotation of the first rotating shaft 902 will drive the first spur gear 903 to rotate. The rotation of the first spur gear 903 will drive the second spur gear 904 to rotate. The diameter of the first spur gear 903 is smaller than the diameter of the second spur gear 904. Therefore, the pneumatic motor 901 can reduce the speed and increase the torque through the first spur gear 903 and the second spur gear 904; the rotation of the second spur gear 904 will drive the second rotating shaft 905 to rotate. The rotation of the second rotating shaft 905 will drive the screw rod 906 to rotate. The rotation of the screw rod 906 will discharge the particles and coal in the groove at the bottom end of the support plate 203; the first spur gear 903 and the second spur gear 904 can reduce the speed and increase the torque, so that the driving force of the screw rod 906 can be large, and the coal slag can be better discharged from the equipment. When the screw rod 906 pushes the coal slag at a slower speed, the impact force on the coal slag particles during the transportation process is smaller, which reduces the repeated crushing of the coal slag. This helps to maintain the integrity of the coal slag particles and reduce the generation of fine coal slag, thereby improving the utilization value of the coal slag. When the spiral rod 906 pushes the coal slag at a slower speed, the resistance and impact force it encounters are also reduced accordingly, which helps to reduce the wear of key components such as the spiral rod and bearings. In long-term operation, this can extend the service life of the equipment and reduce maintenance costs.
