Description

Technical Field

[0001] The present invention relates to the technical field of air pollution control, and in particular to a water sprinkling and dust reduction device for mining in mining areas. Background Art

[0002] A large amount of dust will be generated during the mining process in the mining area. For example, blasting operations, drilling, cutting and crushing will all generate dust. In the dusty area, fans are used to draw the dust in time and sprinkle water to reduce the dust, so as to avoid large-scale sprinkling of water underground causing moisture on the ground.

[0003] There is a publication number CN119244305B, titled "A Mining Water Sprinkler Dust Reduction Device," comprising a watering box and a blower body symmetrically arranged at its upper end. A bracket is symmetrically arranged on the upper portion of the watering box, and the oily dust auxiliary processing assembly comprises a stepper motor, a baffle, a dust-free cloth, and two symmetrically arranged rollers. The rollers are rotatably arranged within slots, the baffles are parallelly mounted on the upper portion of the watering box, the dust-free cloth is sleeved between the outer sides of the two rollers, and one of the rollers is connected to the output shaft of the stepper motor. Dust is concentrated by two symmetrically arranged blowers, and the water sprayed from the upper sprinkler nozzle fully contacts the dust. During this process, the oily dust in the dust can effectively contact the dust-free cloth at the lower end. The dust-free cloth has excellent adsorption properties, which adsorbs the oily dust onto the dust-free cloth for centralized collection.

[0004] In the above-mentioned existing technical solutions, a fan is used to gather dust and then transport it, so that the dust and water come into contact with each other to achieve the effect of dust reduction. However, during the mining process in the mining area, the dust particles generated are relatively small, and these smaller particles will bypass the droplets. Secondly, some dust is hydrophobic. Since the contact time between the dust particles and water is relatively short, the dust reduction effect is not ideal. Summary of the Invention

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Example 1, with reference to Figure 1-3 A water sprinkling dust suppression device for mining in a mining area includes a conveying pipe 1. Dust moves in the conveying pipe 1 under the drive of air flow. A water tank 2 is fixedly installed at the lower end of the conveying pipe 1. The bottom of the water tank 2 is inclined, and the water in the water tank 2 flows toward the air inlet. Two notches 5 are provided at the lower end of the inner side of the conveying pipe 1. A roller 18 is rotatably provided between the two notches 5. A plurality of blades 14 are evenly installed on the outer side of the roller 18, and the lower ends of the blades 14 extend into the box 2.

[0027] A water tank 2 is installed at the top of the delivery pipe 1, and a spray rack 4 is installed on the inner side of the water tank 2, and the spray rack 4 is located above the drum 18. A water pump 20 is fixedly installed on the back of the delivery pipe 1, and the water in the water tank 2 is delivered to the spray rack 4 through the water pump 20.

[0028] A gap is provided between the blades 14 on the outside of the drum 18 and the communication box 3 .

[0029] Reference Figure 6 The end of the blade 14 is symmetrically provided with a folded edge 12, and a through hole 13 is opened on the blade 14. A plurality of receiving grooves 21 are evenly opened on the surface of the blade 14. The receiving groove 21 on the blade 14 can increase the contact area with the dust. At the same time, when the blade 14 rotates to the lower end, the water and dust are mixed and move toward the lower end of the blade 14 until most of the water and dust move to the folded edge 12 position. A through hole 13 is set at the position of the folded edge 12. When the blade 14 extends below the water flow level inside the water tank 2, a part of the water flow will pass through the through hole 13, so that the folded edges 12 on both sides of the blade 14 can contact each other with the water, and then the water passes between the two folded edges 12 to transfer the dust into the water tank 2.

[0030] When the dust generated in the mining area contains small particles and hydrophobic granular dust, the ordinary water sprinkling dust reduction method cannot effectively combine water with dust to achieve the effect of complete dust reduction.

[0031] For this, the dust is driven by the fan into the inside of the conveying pipe 1, the drum 18 is rotatably arranged on the inner side of the conveying pipe 2, the bottom of the water tank 2 is arranged in an inclined manner, and the flowing water provides kinetic energy to the hollow drum 18 when the flowing water contacts the blades 14 on the outer side of the drum 18, so that the drum 18 can rotate smoothly. Since the drum 18 is located on the path of the dust, when the dust passes through the position of the drum 18, the dust will contact the outer surface of the drum 18, and the drum 18 can block the dust. At the same time, the upper end of the communication box 3 is provided with a spraying frame 4, and water is sprayed from the spraying frame 4 to form a water curtain. When the water curtain contacts the dust, it can also effectively block and reduce the dust. In addition, the sprayed water can also form a water film on the outer surface of the drum 18, which can have an adsorption effect after contacting the dust. The water curtain sprayed from the upper spraying frame 4 can also continuously contact the outer surface of the drum 18. In this way, the dust attached to the outer surface of the drum 18 is washed into the water tank 2. The drum 18 and the blades 14 form a blocking piece, and the water curtain sprayed from the upper spraying frame 4 realizes the effect of dust reduction.

[0032] At the same time, the kinetic energy of the water flow contacts the blades 14, which not only transmits the kinetic energy to the blades 14, but also washes the dust on the blades 14 down with the help of the mutual contact between the water flow and the blades 14. The washed dust flows along the water flow to the other side of the water tank 2.

[0033] Since the dust moves in the conveying pipe 1 by the airflow, the airflow speed will decrease significantly when the dust is blocked by the drum 18. Therefore, the communication box 3 is arranged above the drum 18, and part of the airflow enters the inside of the communication box 3 and then moves to the other side of the drum 18 from the inside of the communication box 3.

[0034] Embodiment 2, reference Figure 4-5 The difference between this embodiment and embodiment 1 is that two inclined plates 7 are symmetrically arranged on both sides of the drum 18 through the regulating assembly 10. The inclined plate 7 is movably arranged on the inner side of the conveying pipe 1 through the hinged rod 17. One end of the hinged rod 17 is sleeved with a second sleeve 16, and the other end of the hinged rod 15 is connected with the regulating assembly 10. The regulating assembly 10 includes a rotating shaft 101, a crankshaft 102 and a first sleeve 103. The rotating shaft 101 is installed at both ends of the drum 18, and the hollow drum 18 rotates through the rotating shaft 101. The crankshaft 102 is installed at one end of the rotating shaft 101, and the first sleeve 103 is sleeved on the crankshaft 102. The outer side of the first sleeve 103 is connected with one end of the connecting rod 15.

[0035] A fixing seat 19 is fixedly installed on the top of the inclined plate 7, and a groove 8 is opened at the upper end of the fixing seat 19. A plurality of notches 9 are evenly opened on the side of the fixing seat 19 close to the roller 18, and the notches 9 are located at the upper end of the groove 8. A baffle 6 is inclinedly provided on the side of the fixing seat 19 away from the roller 18.

[0036] During the rotation of the drum 18, centrifugal force is generated, which will throw out the water and dust attached to the blades 14 and the surface of the drum 18, causing the dust to accumulate on one side of the inclined plate 7, affecting the dust collection effect. When the amount of dust accumulation is large, it may also affect the smooth rotation of the drum 18.

[0037] To this end, notches 5 are provided on both sides of the drum 18, and a swingable inclined plate 7 is provided between the two notches 5. It should be noted that the inclined plate 7 is tilted downward toward the side close to the drum 18 in the initial state, and when the inclined plate 7 swings subsequently, it always maintains an inclined state at different angles. After the drum 18 obtains power, it drives the crankshafts 102 at both ends to rotate, and one side of the inclined plate 7 is movably connected using a hinged rod 17. In this way, during the rotation of the crankshaft 102, the power is transmitted to the inclined plate 7 through the connecting rod 15, so that the inclined plate 7 can achieve periodic swing. During the swinging of the inclined plate 7, the dust and water on the upper surface of the inclined plate 7 can be shaken off, and the dust will enter the inner side of the water tank 2 from the lower end of the inclined plate 7 along with the water.

[0038] Example 3, reference Figure 7 The difference between this embodiment and Embodiment 1 and Embodiment 2 is that a plurality of groups of floating components 11 are distributed in a rectangular array at the bottom of the water tank 2 below the drum 18. The floating components 11 include a rope body 111, a float 112 and a cleaning wipe 113. The bottom of the rope body 111 is fixedly installed at the bottom position of the water tank 2. The upper end of the outer side of the rope body 111 is respectively provided with multiple rope bodies 111 and floats 112, and the rope bodies 111 and floats 112 are staggered. When the drum 18 rotates, its external blades 14 come into contact with the float 112 and the cleaning wipe 113 in turn.

[0039] The mining area contains some large equipment, and when the equipment is in operation, some sticky dust is also generated. After the dust adheres to the outer surface of the blades 14 and the roller 18, it is difficult to separate it easily.

[0040] To this end, a number of floating components 11 consisting of a rope body 111, a float 112 and a cleaning wipe 113 are distributed in a rectangular array at the bottom of the water tank 2. The float 112 has buoyancy. Under the action of the buoyancy, the rope body 111 and the cleaning wipe 113 are in a straight state. At the same time, the rope body 111 is subjected to the lateral force of the water flow, and the rope body 111 is in an inclined state in the water tank 2. In this way, when the blade 14 rotates, it will contact the float 112 and the cleaning wipe 113 at the top of the rope body 111. During the contact process, the float 112 and the cleaning wipe 113 rub against the surface of the blade 14, so that the dust falls off and is transferred to the other side of the water tank 2 with the water flow.

[0041] Example 4, reference Figure 7 The difference between this embodiment and embodiment 1, embodiment 2 and embodiment 3 is that a thread 22 is tied between the lower ends of the rope bodies 111 in the same row, and the thread 22 is located below the float 112 and the cleaning wipe 113.

[0042] There is no float 112 at the bottom of the rope body 111. In order to prevent the rope bodies 111 from being entangled with each other, the spacing between adjacent rope bodies 111 is adjusted to prevent entanglement. At the same time, in order to prevent the lower ends of the rope bodies 111 from curling and entanglement, silk threads 22 are used to fix the rope bodies 111 in the same row to limit the swing amplitude of the lower ends of the rope bodies 111 and avoid the problem of curling and entanglement of the lower ends of the rope bodies 111.

[0043] The working principle of the device is: When the dust generated in the mining area contains small particles and hydrophobic granular dust, the ordinary water sprinkling dust reduction method cannot effectively combine water with dust to achieve the effect of complete dust reduction.

[0044] To this end, the fan is used to drive the dust into the interior of the conveying pipe 1 under the influence of the air flow. The roller 18 is rotatably arranged on the inner side of the conveying pipe 2. The bottom of the water tank 2 is inclined. When the flowing water contacts the blades 14 on the outside of the roller 18, it provides kinetic energy to the hollow roller 18, so that the roller 18 can rotate smoothly. Since the roller 18 is located on the path that the dust must pass through, when the dust passes through the position of the roller 18, it will contact the outer surface of the roller 18. The roller 18 thereby realizes the blocking of the dust. At the same time, a spray nozzle is provided on the upper end of the connecting box 3. The shower rack 4 sprays water to form a water curtain that contacts the dust, which can also effectively block and reduce the dust. Secondly, the sprayed water can also form a water film on the outer surface of the drum 18. The water film can have an adsorption effect after contacting the dust. The water curtain sprayed from above can also continuously contact the outer surface of the drum 18. In this way, the dust attached to the outer surface of the drum 18 is washed into the water tank 2. The blocking member composed of the drum 18 and the blades 14 is combined with the water curtain sprayed from the shower rack 4 above to achieve the effect of dust reduction.

[0045] At the same time, the kinetic energy of the water flow is used to contact the blades 14, which not only transfers the kinetic energy to the blades 14, but also washes away the dust on the blades 14 with the help of the mutual contact between the water flow and the blades 14. The washed dust flows along the water flow to the other side of the water tank 2.

[0046] Since dust moves in the conveying pipe 1 through air flow, when it is blocked by the roller 18, the gas flow rate will drop significantly. Therefore, a connecting box 3 is set above the roller 18, and part of the air flow enters the connecting box 3 and is then transferred from the inside of the connecting box 3 to the other side of the roller 18.

[0047] During the rotation of the drum 18, centrifugal force is generated, which will throw out the water and dust attached to the blades 14 and the surface of the drum 18, causing the dust to accumulate on one side of the inclined plate 7, affecting the dust collection effect. When the amount of dust accumulation is large, it may also affect the smooth rotation of the drum 18.

[0048] To this end, notches 5 are provided on both sides of the drum 18, and a swingable inclined plate 7 is provided between the two notches 5. It should be noted that the inclined plate 7 is tilted downward toward the side close to the drum 18 in the initial state, and when the inclined plate 7 swings subsequently, it always maintains an inclined state at different angles. After the drum 18 obtains power, it drives the crankshafts 102 at both ends to rotate, and one side of the inclined plate 7 is movably connected using a hinged rod 17. In this way, during the rotation of the crankshaft 102, the power is transmitted to the inclined plate 7 through the connecting rod 15, so that the inclined plate 7 can achieve periodic swing. During the swinging of the inclined plate 7, the dust and water on the upper surface of the inclined plate 7 can be shaken off, and the dust will enter the inner side of the water tank 2 from the lower end of the inclined plate 7 along with the water.

[0049] The fixed seat 19 is provided at the top of the inclined plate 7, and the upper end of the fixed seat 19 is provided with a groove 8 for collecting splashed water. During the swinging of the inclined plate 7, the water leaks out of the side notch 9, and the leaked water can also slide off the inclined plate 7 to carry away the dust.

[0050] The mine area contains some large equipment, and the equipment also generates some viscous dust when running. After the dust adheres to the outer surface of the blade 14 and the roller 18, it is difficult to remove the dust.

[0051] Therefore, a plurality of floating assemblies 11 composed of a rope body 111, a floating body 112 and a cleaning cloth 113 are arranged in a rectangular array at the bottom of the water tank 2. The floating body 112 has buoyancy, and the rope body 111 and the cleaning cloth 113 are in a straight state under the action of the buoyancy. The rope body 111 is in an inclined state in the water tank 2 under the action of the lateral force of the water flow. In this way, when the blade 14 rotates, the floating body 112 and the cleaning cloth 113 at the top of the rope body 111 are in contact with each other. During the mutual contact, the floating body 112 and the cleaning cloth 113 rub against the surface of the blade 14 to remove the dust and transfer it to the other side of the water tank 2 along with the water flow.

[0052] The bottom of the rope body 111 is not provided with a floating body 112. In order to prevent the rope body 111 from being entangled with each other, the spacing between adjacent rope bodies 111 is adjusted to prevent entanglement. In order to avoid the lower end of the rope body 111 from being curled and entangled, silk threads 22 are used to fix the rope bodies 111 in the same column to limit the swinging amplitude of the lower end of the rope body 111 and avoid the problem of curling and entangling of the lower end of the rope body 111.

[0053] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
