Description

Technical Field

[0001] The invention relates to the technical field of dust suppression equipment, in particular to an automatic spray dust suppression device for a mine. Background Art

[0002] Coal is a solid combustible mineral that is gradually formed by ancient plants buried underground and undergoing complex biochemical and physicochemical changes. Coal mining is the process of mining coal seams deep underground. The process of extracting coal is called coal mining.

[0003] Coal mines emit a large amount of dust into the air during production, storage, transportation and tunnel excavation. The most harmful dust to human health is respirable dust. If people inhale respirable dust for a long time, it will cause pulmonary fibrosis and lead to pneumoconiosis (silicosis, coal lung disease, coal silicosis). Moreover, under certain conditions, coal dust in the mine can cause coal dust explosion, causing casualties and serious damage to mine equipment, resulting in serious mine disasters. Therefore, dust reduction devices are usually installed in mine tunnels.

[0004] At present, spray dust reduction is usually used for dust reduction in tunnels. However, spraying in tunnels cannot achieve automatic dust reduction in the past, and the spray device needs to be opened and closed manually. If the person neglects to close it in time, it will cause water accumulation in the tunnel, making it difficult for pedestrians. In severe cases, it will affect ventilation. When the spray device is in use, the particle size of the droplets it sprays is usually fixed. Therefore, in the case of high-density, low-particle dust, the amount of water used will be more, which will result in water waste. Summary of the invention

[0005] The object of the present invention is to provide an automatic spray dust suppression device for mines to solve the problems raised in the above background technology.

[0031] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0032] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0033] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0034] See also Figure 1-Figure 8 In an embodiment of the present invention, a mine automatic spray dust suppression device includes:

[0035] A casing 1, on which a wind conduction component and a water conduction component are arranged, wherein the wind conduction component comprises a wind connection pipe 2 arranged on the casing 1, and a blocking piece is slidably arranged in the wind connection pipe 2, and the blocking piece is moved to change the ventilation volume of the wind connection pipe 2;

[0036] Preferably, see Figure 1 , Figure 2 , Figure 3 The wind connecting pipe 2 is provided with an air inlet 201 and an air outlet 202. The air inlet 201 is connected to an air supply device arranged outside the casing 1 (not shown in the figure), and the air outlet 202 is connected to a main air supply pipe 3 arranged on the wall of the alley. When the wind connecting pipe 2 is in a conducting state, the air supply device can supply air toward the main air supply pipe 3 through the air inlet 201 and the air outlet 202.

[0037] The blocking member includes a movable sleeve 21 slidably disposed on the housing 1, and a conducting groove 2101 is formed on the movable sleeve 21;

[0038] For details, please refer to Figure 7 The movable sleeve 21 is provided with a conducting groove 2101 on one side facing the air inlet 201. In detail, the conducting groove 2101 is as follows: Figure 7 The "upper narrow and lower wide" state is shown, and the upper and lower ends of the movable sleeve 21 are connected. In the initial state, the lower end of the movable sleeve 21 abuts against the end of the wind connection pipe 2 away from the air outlet 202, and the conducting groove 2101 does not overlap with the air inlet 201. At this time, the air inlet 201 is in a blocked state;

[0039] In actual use, by driving the movable sleeve 21 to rise along the axial direction of the wind connection pipe 2, the conduction groove 2101 can be forced to overlap with the air inlet 201. When the conduction groove 2101 overlaps with the air inlet 201, the air inlet 201 is connected, and then the wind can enter the wind connection pipe 2 through the air inlet 201, and then be discharged from the air outlet 202 to the main air supply pipe 3, so as to be combined with the hydraulic conduction component later, so as to perform a spraying operation;

[0040] As the movable sleeve 21 continues to rise, the overlapping area between the conductive groove 2101 and the air inlet 201 will gradually increase, thereby increasing the ventilation volume entering the wind connecting pipe 2 per unit time, and then reducing the particle size of the spray droplets after subsequent combination with the hydraulic conductive component, so as to be suitable for dust reduction operations with smaller dust particle sizes.

[0041] For further information, see Figure 1 , Figure 2 , Figure 3 , Figure 5 The hydraulic conduction assembly includes a hydraulic connection pipe 4 detachably mounted on the housing 1, and the hydraulic connection pipe 4 is connected to a conduction member disposed in the housing 1;

[0042] For details, please refer to Figure 1 , Figure 2 , Figure 3 The upper and lower ends of the hydraulic connecting pipe 4 are respectively provided with a water inlet 401 and a water outlet 402, the water inlet 401 is connected to a water supply device arranged outside the casing 1 (not shown in the figure), and the water outlet 402 is connected to a main water supply pipe 6 arranged on the wall of the lane, and the main water supply pipe 6 is connected to the main air supply pipe 3 through a confluence pipe 7, as shown in FIG. Figure 1 As shown, multiple groups of manifolds 7 are equidistantly arranged along the width direction of the housing 1, and each group of manifolds 7 is provided with a nozzle 701. When the hydraulic force and the wind force converge at the manifold 7, the nozzle 701 will spray water mist outward, and the water mist can be used to reduce dust floating in the air, and can also be used for dust reduction operations in mine tunnels during coal mining:

[0043] Specifically, a large amount of dust is emitted into the air during the production, storage, transportation and tunnel excavation of coal mines. The most serious harm to human health is respiratory dust. If people inhale respiratory dust for a long time, it will cause pulmonary fibrosis and lead to pneumoconiosis (silicosis, coal lung disease, coal silicosis); and under certain conditions, coal dust in the mine can cause coal dust explosion, causing casualties and serious damage to mine equipment, resulting in serious mine disasters. Therefore, dust suppression devices are usually installed in mine tunnels. In the present invention, when the conductive member and the wind connection pipe 2 are in the conductive state at the same time, the air supply device and the water supply device in the above state can High-speed air flow and high-pressure water are delivered to the wind connecting pipe 2 and the hydraulic connecting pipe 4, and then the high-speed air flow and high-pressure water flowing in the main air supply pipe 3 and the main water supply pipe 6 can be mixed and atomized with the air and water in the confluence pipe 7 to form a high-pressure water mist, which is ejected from the nozzle 701 as a high-pressure atomized flow, forming a negative pressure encirclement around the high-pressure mist flow. On the one hand, it blocks and reduces dust in the tunnel or at dust-producing points, and on the other hand, it replenishes moisture in the tunnel in time to increase the air humidity; at the same time, all solid surfaces in the ventilation tunnel become moist. When the coal dust is floating in the wind, all such moist solid surfaces have the function of absorbing coal dust, thereby minimizing the harm of coal dust to miners.

[0044] For further information, see Figure 3 , Figure 4 , Figure 5 The conducting member includes a ball valve 5 arranged on the hydraulic connecting pipe 4, a valve core 9 is sealed and rotatably installed in the ball valve 5, a docking block 901 is coaxially fixedly arranged on the valve core 9, and the docking block 901 is connected to a driving member rotatably installed on the housing 1;

[0045] Preferably, see Figure 1 , Figure 2 , Figure 3 The housing 1 is provided with a clamp 101, which can clamp the hydraulic connecting pipe 4. With the cooperation of the clamp 101, a detachable connection is achieved between the hydraulic connecting pipe 4 and the housing 1, so that the damaged hydraulic connecting pipe 4 can be replaced later.

[0046] The driving member includes a driving rod 11 rotatably mounted on the housing 1, and a trigger block 1101 is fixedly arranged at one end of the driving rod 11 protruding from the housing 1, and the trigger block 1101 is adapted to a groove provided on the docking block 901, and the other end of the driving rod 11 is connected to a rotating structure provided in the housing 1;

[0047] When the hydraulic connecting pipe 4 is connected to the casing 1, it is necessary to ensure that the trigger block 1101 is engaged with the docking block 901. At this time, the rotating drive rod 11 can drive the valve core 9 to rotate relative to the ball valve 5, thereby opening or closing the hydraulic connecting pipe 4.

[0048] The rotating structure includes a transverse moving member and a rotating member. The transverse moving member includes a moving plate 17 slidably arranged in the housing 1. The moving plate 17 is provided with an engaging groove. The engaging groove cooperates with the trigger assembly to force the moving plate 17 to slide along the width direction of the housing 1.

[0049] Preferably, see Figure 4 , Figure 8 A T-block 1703 is fixedly provided on the above-mentioned movable plate 17. The T-block 1703 is slidably provided in a slide groove 103 opened in the casing 1. The slide groove 103 is opened along the width direction of the casing 1. With the cooperation of the slide groove 103 and the T-block 1703, the movable plate 17 can only slide along the width direction of the casing 1.

[0050] The engaging groove body includes a vertical groove 1702 and an inclined groove 1701 formed on the movable plate 17;

[0051] The rotating member includes a gear 20 rotatably mounted in the housing 1, the gear 20 is coaxially fixedly connected to the driving rod 11, and the gear 20 is meshed with a toothed plate 19 fixedly disposed on the moving plate 17;

[0052] Preferably, in the initial state, the vertical slot 1702 is away from the driving rod 11. When the moving plate 17 is driven by an external force and approaches the driving rod 11, the tooth plate 19 and the gear 20 enter into a meshing transmission state, which can force the gear 20 to rotate counterclockwise (combined with Figure 8 ), until the movable plate 17 reaches the end of its movement stroke, the toothed plate 19 just drives the gear 20 to rotate ninety degrees. At the same time, the driving rod 11 coaxially fixed with the gear 20 can, with the cooperation of the docking block 901 and the trigger block 1101, drive the valve core 9 to rotate ninety degrees relative to the ball valve 5, thereby opening the ball valve 5 so that the water supply device can deliver high-pressure water to the hydraulic connecting pipe 4. At this time, if the movable plate 17 moves in the opposite direction, when the movable plate 17 returns to its initial position, the toothed plate 19 can drive the gear 20 to rotate ninety degrees clockwise, thereby closing the ball valve 5 to cut off the process of the water supply device delivering high-pressure water to the hydraulic connecting pipe 4.

[0053] For further information, see Figure 1 , Figure 2 , Figure 3 The housing 1 is also provided with a sensing area 8, which is in communication with a trigger assembly provided in the housing 1. When the sensing area 8 is triggered, the trigger assembly can drive the wind connection pipe 2 and the water connection pipe 4 to be turned on at the same time, thereby performing spraying;

[0054] Preferably, the sensing area 8 is provided with at least three groups of sensors, including a dust concentration sensor 801 and a laser dust sensor 802. Specifically, the dust concentration sensor 801 can detect the concentration of dust in the tunnel. When the dust concentration sensor 801 detects that the dust concentration in the tunnel reaches a preset value, the trigger component is triggered, which can drive the wind connecting pipe 2 and the hydraulic connecting pipe 4 to be turned on, thereby causing the nozzle 701 to spray, and then the tunnel is subjected to dust reduction treatment.

[0055] The trigger assembly includes a power-on circuit and an elastic trigger member. The power-on circuit includes an iron core 13 fixedly installed in the housing 1. A wire 14 is wound around the iron core 13. One end of the wire 14 is connected to a first electrode sheet 23 arranged in the housing 1, and the other end is connected to a sliding rheostat 12 arranged in the housing 1. The sliding rheostat 12 is connected to a power source 10 fixedly arranged in the housing 1 through the wire 14.

[0056] Preferably, see Figure 5 , Figure 6 The power supply 10 is connected to the second electrode sheet 24 disposed in the housing 1, and the second electrode sheet 24 is connected to the sliding rheostat 12. When the power supply 10 is turned on, the current can flow through the second electrode sheet 24 through the sliding rheostat 12, and then flow to the first electrode sheet 23 through the wire 14.

[0057] The sliding pole piece 1201 of the sliding rheostat 12 is connected to the electric telescopic rod 25 disposed in the housing 1, and the electric telescopic rod 25 is in communication connection with the sensing area 8. When the sensing area 8 is triggered, the electric telescopic rod 25 can push the sliding pole piece 1201 to slide relative to the sliding rheostat 12, thereby changing the access resistance value of the sliding rheostat 12;

[0058] Specifically, the electric telescopic rod 25 is communicatively connected with the laser dust sensor 802. The laser dust sensor 802 can detect the dust particle size in the tunnel. The detected signal can be fed back to the electric telescopic rod 25, thereby driving the electric telescopic rod 25 to move. In detail, in the initial state, the sliding electrode 1201 is close to the second electrode sheet 24. At this time, the resistance group of the sliding rheostat 12 connected to the power-on circuit is the largest. When it is detected that the dust particle size in the tunnel is smaller, the electric telescopic rod 25 can push the sliding electrode 1201 away from the second electrode sheet 24, thereby reducing the resistance value of the sliding rheostat 12 connected to the power-on circuit. Subsequently, with the cooperation of the elastic trigger member, the ventilation volume in the wind connection pipe 2 is increased.

[0059] Further, the elastic trigger member includes a guide rod 18 fixedly arranged in the housing 1, a spring 22 is slidably arranged on the guide rod 18, one end of the spring 22 abuts against the end of the guide rod 18, and the other end abuts against the iron core 13 slidably arranged on the guide rod 18, two groups of connecting rods 16 are fixedly arranged on the iron core 13, one group of connecting rods 16 is fixedly connected to the movable sleeve 21, and the other group of connecting rods 16 is fixedly arranged on the protruding column 1601;

[0060] For details, please refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , the connecting rod 16 fixedly connected to the movable sleeve 21 is slidably arranged in the through slot 102 opened on the housing 1, and is placed in the leading slot 203 opened on the wind connection pipe 2. In the initial state, the spring 22 is in a compressed state. The spring 22 in the compressed state pushes the iron core 13 away from the iron core 13. The protruding column 1601 is located at the end of the stroke of the inclined slot 1701 away from the vertical slot 1702, and the dust concentration sensor 801 is connected to the power supply 10 for communication;

[0061] When the dust concentration sensor 801 detects that the dust concentration in the tunnel reaches a preset value, the detection signal of the dust concentration sensor 801 is fed back to the power supply 10, thereby driving the power supply 10 to turn on, and then the current flows to the first electrode sheet 23 through the sliding rheostat 12 and the wire 14. At this time, the wire 14 wound around the iron core 13 can make the iron core 13 instantaneously magnetized. At this time, the magnetized iron core 13 can attract the armature 15, thereby forcing the armature 15 to move toward the iron core 13 along the axial direction of the guide rod 18. In this process, the iron core 13 can drive the movable sleeve 21 to move the wind connection pipe 2, and open the air inlet 201. At the same time, the contact and extrusion between the protruding column 1601 following the movement of the armature 15 and the wall of the inclined groove 1701 can force the movable plate 17 to move away from the guide rod 18. Then, with the cooperation of the tooth plate 19 and the gear 20, the valve core 9 rotates 90 degrees to conduct the ball valve 5. At this time, the nozzle 701 spraying outward can reduce dust in the lane. After the protruding column 1601 separates from the inclined groove 1701, the protruding column 1601 that continues to move can slide in the vertical groove 1702. At this time, the conduction of the ball valve 5 is the largest. When the armature 15 moves a larger distance due to the magnetic enhancement of the iron core 13, the conduction of the ball valve 5 will always be stable at the maximum state.

[0062] In particular, before the dust concentration sensor 801 feeds back the dust concentration in the tunnel, the laser dust sensor 802 can first detect the dust diameter in the tunnel, and the detection result will be fed back to the electric telescopic rod 25. When the dust particle size is finer, the access resistance of the sliding rheostat 12 is smaller, until the dust concentration in the tunnel reaches the preset value, the laser dust sensor 802 stops detecting, and then the dust concentration sensor 801 drives the power supply 10 to turn on. At the same time, the magnetism of the iron core 13 will increase relatively, and then the distance that the armature 15 is attracted to drive the moving sleeve 21 to move will also increase, so that the ventilation volume in the wind connection pipe 2 increases. At this time, the smaller the particle size of the water mist sprayed by the nozzle 701, the better it can combine with the fine dust particles, improve the dust reduction effect, and by reducing the particle size of the mist particles, the efficiency of the mist particles in capturing dust can be improved, thereby reducing the amount of water used in the case of high-density and low-particle-size dust;

[0063] After the dust concentration in the tunnel is reduced to a safe level, the laser dust sensor 802 can resume working, and the dust concentration sensor 801 can cut off the power supply 10, and then the iron core 13 disappears, and the armature 15 returns to the initial position under the drive of the spring 22. In this process, the armature 15 can drive the movable sleeve 21 and the movable plate 17 to return to the initial position, thereby closing the wind connection pipe 2 and the hydraulic connection pipe 4, so as to reduce dust in the tunnel later;

[0064] The above process does not require manual operation, which improves the timeliness and accuracy of dust reduction in the tunnel and eliminates the problem of water accumulation in the tunnel due to human negligence that affects normal production.
