Description

Technical Field

[0001] The invention belongs to the technical field of dust suppression equipment, and in particular relates to dust suppression equipment for mining. Background Art

[0002] During mining operations, a large amount of dust is generated in the mining area, especially inside the mine. This dust needs to be absorbed and treated using dust suppression equipment.

[0003] One of the prior art is a dust reduction device for mining disclosed in a Chinese patent (CN116696446A), which belongs to the technical field of mine dust removal. The dust reduction device for mining of the present invention includes a support plate, a water storage tank, a dust reduction mechanism and a recovery mechanism. The water storage tank, the dust reduction mechanism and the recovery mechanism are all arranged on the support plate. The first water inlet of the water storage tank is externally connected to a water pipe. The dust reduction mechanism is connected to the water outlet of the water storage tank. The water inlet of the recovery mechanism is connected to the drainage end of the dust reduction mechanism. The drainage end of the recovery mechanism is connected to the second water inlet of the water storage tank. The dust reduction mechanism includes a dust reduction device, an angle adjustment component and a displacement adjustment component. The angle adjustment component is fixedly arranged on the support plate, and the displacement adjustment component is arranged on the angle adjustment component. The dust reduction device includes a first dust reduction component and a second dust reduction component. The first dust reduction component and the second dust reduction component are both slidably arranged on the displacement adjustment component. The first dust reduction component and the second dust reduction component are both connected to the water outlet of the water storage tank. By adopting the above scheme, during use, the fan in the dust reduction mechanism blows air backwards to form negative pressure, blowing the dust-laden air toward the spiral tube at the rear, and the water mist sprayed forward by the spiral tube will also be blown backwards by the wind force of the fan, causing the mixing area of ​​the water mist and the dust-laden air to move backward. At the same time, the water mist is subjected to a reaction force opposite to the spraying direction, and its speed is slowed down, causing the speed of the water mist and the dust in the degraded adsorbed gas to slow down, thereby reducing the dust reduction rate of the device. At the same time, the fan is located on the front side of the spiral tube, at the upwind port, and the dust-laden gas first passes through the fan and then enters the dust reduction treatment in front of the spiral tube, resulting in dust accumulation on the fan blades after long-term use, which is difficult to clean.

[0004] The second prior art discloses a spraying device for dust prevention and reduction in mining, such as the Chinese patent (CN117605518A), which includes a transport box, which is divided into a water storage area and a dust collection area by a partition plate, the dust collection area and the water storage area are arranged front and back, the front end of the upper surface of the transport box is provided with a dust removal part connected to the dust collection area, the rear end of the upper surface of the transport box is provided with a spraying dust reduction part connected to the water storage area, the lower surface of the transport box is provided with moving wheels around, and the lower end of the right side of the transport box is connected to a water supply pipe for supplying water to the water storage area; With the above solution, the device adsorbs and degrades the dust in the air by spraying water mist. This method requires connecting the water pipe in the water storage area to supply water, which limits the movement range of the device by the length of the water supply pipe of the water supply pipe. At the same time, compared with dry adsorption dust removal, spray dust removal consumes a large amount of water resources, which cannot be recycled. After the dust is degraded to the ground and evaporated into the air, it causes waste of water resources. In addition, the dust removal efficiency of the spray directly diffused into the environment is greatly affected by the wind, resulting in unstable dust removal effect.

[0005] In summary, the following defects exist in the prior art: First, the fan blows air backward to form a negative pressure, blowing the dust-containing air toward the spiral pipe at the back. The water mist sprayed forward by the spiral pipe will also be blown backward by the wind force of the fan, resulting in the backward movement of the mixing area of the water mist and the dust-containing air. At the same time, the water mist is subjected to a reaction force opposite to the spraying direction, and its speed slows down, resulting in a slowdown in the speed of the water mist and the dust in the degradation and adsorption gas, reducing the dust removal rate of the device; Second, the dust-containing gas first passes through the fan and then enters the front of the spiral pipe for dust removal treatment. After long-term use, dust is likely to accumulate on the blades of the fan and is difficult to clean; Third, spray dust removal consumes a large amount of water resources, which cannot be recycled. After the dust is degraded to the ground and evaporated into the air, it causes waste of water resources and the dust removal efficiency of the spray directly diffused into the environment is greatly affected by the wind, resulting in unstable dust removal effect.

[0018] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. Example

[0019] like Figures 1 to 6 As shown: The prior art in this embodiment has the following problems: The inventors have found the following defects in the prior art: First, the fan blows air backwards to form a negative pressure, blowing the dust-laden air to the rear spiral tube, and the water mist sprayed forward by the spiral tube will also be blown backwards by the wind force of the fan, causing the mixing area of ​​the water mist and the dust-laden air to move backwards. At the same time, the water mist is subjected to a reaction force opposite to the spraying direction, and its speed slows down, causing the speed of the water mist and the dust in the degraded adsorbed gas to slow down, thereby reducing the dust removal rate of the device; Second, the dust-laden gas first passes through the fan and then enters the spiral tube for dust reduction treatment, resulting in dust easily accumulating on the fan blades after long-term use, which is difficult to clean; Third, the spray dust reduction and adsorption dust reduction consumes a large amount of water resources, which cannot be recycled. The degraded dust evaporates into the air after reaching the ground, resulting in a waste of water resources and the dust removal efficiency of the spray directly diffuses into the environment is greatly affected by the wind force, resulting in unstable dust removal effect; Therefore, the inventor provides a dust reduction device for mining, including a device body, a base 1, and a controller 2. The device body is arranged above the base 1, the controller 2 is arranged on the front side of the device body, and the device body and the controller 2 are connected by telecommunication; the device body also includes a dust suction mechanism 3, a dust reduction mechanism 4, and a cleaning mechanism 5. The dust suction mechanism 3 is arranged on the outside of the dust reduction mechanism 4, and the cleaning mechanism 5 is arranged on the outside of the dust suction mechanism 3.

[0020] By adopting the above scheme, the device is set on a movable vehicle-mounted platform and moved to the work point where dust removal is required, so that the dust suction mechanism 3 is aligned with the channel, and the dust suction mechanism 3 continuously absorbs dust-containing air into the space. After the dust is adsorbed and filtered out by the dust reduction mechanism 4, the air is compressed by the dust suction mechanism 3, and the compressed air is transported to the front end of the dust suction mechanism 3. By transporting the compressed air backward, power is provided to the dust suction mechanism 3 to increase the suction effect. At the same time, the dust reduction mechanism 4 can also use the compressed air generated by the dust suction mechanism 3 to produce high-pressure water mist to clean the dust reduction mechanism 4. Example

[0021] like Figures 1 to 5 As shown: Further, the dust collection mechanism 3 also includes a dust hopper 6, a dust collection cylinder 7, an air intake pipe 8, an electric valve a9, a compressor unit 10, a compressed gas tank 11, a compressed gas pipe 12, an electric valve b13, an annular pipe 14, a nozzle 15, and a power fan 16.

After the compressor unit 10 compresses the air, the compressed air is output to the compressed air tank 11 through the compressed air pipe 12 for storage. The controller 2 controls the compressed air tank 11 to release the compressed air into the annular tube 14, and the nozzle 15 on the right side of the annular tube 14 sprays the compressed gas along the inside of the dust collection tube 7. The power fan 16 rotates under the action of the gas sprayed from the nozzle 15. Under the joint action of the compressor unit 10, the compressed air of the nozzle 15 and the power fan 16, the air flow in the dust collection cylinder 7 is strengthened, and the effect of the dust collection hopper 6 to suck out the dust-containing air is enhanced. At the same time, the dust reduction mechanism 4 on the right side is driven to rotate to absorb dust. The guide ring 17 on the left side of the annular tube 14 smoothly fills the space between the right side of the annular tube 14 and the dust collection cylinder 7 and the dust collection hopper 6, providing a good airflow environment for the entry of dust-containing air. During the process, the compressed air drives the power fan 16 to rotate. The fan blades are not easily contaminated with dust under the flushing of the compressed air, which provides power for the dust collection and dust reduction mechanisms of the device while ensuring the cleanliness of the power fan 16. Example

[0022] like Figures 1 to 5 As shown: Furthermore, the dust reduction mechanism 4 further includes a transmission shaft 18 and an adsorption blade 19, wherein the transmission shaft 18 is rotatably arranged on the right side of the power fan 16, and the adsorption blade 19 is arranged on the side of the transmission shaft 18; Further, the adsorption blade 19 is provided with a spiral blade structure with an activated carbon plate adsorption material on the surface; Among them, the transmission shaft 18 drives the spiral blades to rotate in the dust collector 7 under the action of the power fan 16. During the rotation, the dust in the air is washed onto the blades with activated carbon plates and adsorbed, thereby achieving the purpose of dust removal. The power disturbance airflow provided by the power fan 16 is used to enhance the effect of adsorption and dust removal. Example

[0023] like Figure 6 As shown: Further, the adsorption blade 19 is provided with a fan blade structure with an activated carbon plate adsorption material on the surface; Among them, the fan blades with activated carbon plate adsorption materials on the surface can also have the effect of disturbing the airflow to adsorb dust. In an environment with a lot of dust in the air, different numbers and shapes of blades can be set to enhance the dust removal effect. Example

[0024] like Figures 1 to 5 As shown: Furthermore, the cleaning mechanism 5 also includes a cleaning water tank 20, a water supply pipeline 21, an atomizing water pipe 22, an electric valve c23, a bypass air pipe 24, an electric valve d25, an atomizing air pipe 26, an electric valve e27, an atomizing chamber 28, a sewage hopper 29, a sewage pipe 30, an electric valve f31, a sewage tank 32, a sewage pipeline 33, and an exhaust pipeline 34. The cleaning water tank 20 is arranged above the dust collection cylinder 7, the water supply pipeline 21 is arranged on the right side of the cleaning water tank 20, the atomizing water pipe 22 is arranged on the left side of the cleaning water tank 20, the electric valve c23 is arranged on the atomizing water pipe 22, the bypass air pipe 24 is arranged above the cleaning water tank 20, the upper inlet of the bypass air pipe 24 is connected to the compressed air pipe 12, and the lower part of the bypass air pipe 24 connected to the cleaning water tank 20, the electric valve d25 is arranged on the bypass air pipe 24, the atomizing air pipe 26 is arranged between the atomizing water pipe 22 and the compressed air pipe 12, the electric valve e27 is arranged on the atomizing air pipe 26, the atomizing chamber 28 is arranged on the left side of the atomizing water pipe 22, the outlet of the atomizing water pipe 22 is connected to the upper inlet of the atomizing chamber 28, the lower outlet of the atomizing chamber 28 is connected to the compressed air pipe 12 through a pipeline, the sewage hopper 29 is arranged below the dust collection cylinder 7, the sewage pipe 30 is arranged on the right side of the sewage hopper 29 and connected to the sewage tank 32 below the right side of the sewage pipe 30, the electric valve f31 is arranged on the sewage pipe 30, the sewage discharge pipeline 33 is arranged on the front side of the sewage tank 32, and the exhaust pipeline 34 is arranged above the sewage tank 32; Further, the sewage hopper 29 is provided with a bottom structure inclined to the right; Among them, when the device is working normally, the electric valve c23, the electric valve d25, the electric valve e27, and the electric valve f31 are closed, the device performs normal dust removal operations, and the cleaning mechanism 5 is not in operation. When the device has been running for a period of time, the adsorption blades 19 are covered with dust, resulting in a decrease in adsorption capacity. The operator controls the dust suction mechanism 3 to close through the controller 2. At this time, the electric valve a9 and the electric valve b13 are closed, and the electric valve c23, the electric valve d25, the electric valve e27, and the electric valve f31 are opened. The compressed gas tank 11 supplies air to the cleaning water tank 20 through the bypass air pipe 24. The water in the cleaning water tank 20 is quickly transported to the atomizing chamber 28 through the atomizing water pipe 22 under pressure. In the process, the compressed air is inflated into the atomizing water pipe 26 to carry the gas. The clean water moves at high speed into the atomizing chamber 28 and expands and atomizes to form water mist, and then the water mist enters the annular tube 14 and is sprayed out by the nozzle 15, so that the water mist drives the power fan 16 and the dust suppression mechanism 4 to rotate. In the process, the water mist adheres to the blades of the power fan 16 and the adsorption blades 19 and condenses into water droplets to clean the blades. At the same time, the high-pressure water mist drives the blades to rotate and throw off the sewage. The sewage gathers on the inner wall of the dust suction cylinder 7 to the sewage hopper 29 and flows into the sewage tank 32 for storage. The gas is discharged through the air valve on the exhaust pipe 34. When it needs to be recycled, the valve on the sewage pipe 33 can be opened to transfer and recycle the sewage. The clean water in the clean water tank 20 can be replenished to the water supply point through the water supply pipe 21 when the device is idle. In this way, the dust removal efficiency of the device is ensured to be stable, and the automatic cleaning device can also collect sewage for recycling.

[0025] To sum up, the device is provided with a dust suction mechanism 3 which generates compressed air by generating negative pressure through the compressor unit 10, and the compressed air is used again to provide power for the power fan 16, so as to generate a circulating airflow inside the device, and a dust reduction mechanism 4 is provided in the direction of the airflow. The dust-containing airflow blows on the surface of the dust reduction mechanism 4, so that the adsorption blades 19 adsorb dust, thereby enhancing the adsorption and dust removal effect of the device. At the same time, the power fan 16 is blown by compressed air, so that dust is not easily accumulated on the fan surface; a cleaning mechanism 5 is provided, which can utilize the compressed air generated by the dust suction mechanism 3 to generate high-pressure water mist, blow the power fan 16 to drive the dust reduction mechanism 4 to rotate, and automatically clean the device while ensuring the stability of the dust removal efficiency of the device, and can also recycle sewage to save water resources.

[0026] Based on the above technical solution, the present invention provides a method for using a dust suppression device for mining, which specifically includes the following steps: S1: In the dust removal state, the device is placed on a movable vehicle-mounted platform, moved to the working point where dust removal is required, and the electric valve a9, the electric valve b13 and the compressor unit 10 are opened through the controller 2; S2: Use the controller 2 to control the compressed gas tank 11 to release compressed air to drive the power fan 16 to rotate and inhale dusty air. The power fan 16 rotates to drive the spiral blades to rotate in the dust collection cylinder 7. During the rotation, the dust in the air is washed onto the blades with the activated carbon plate and adsorbed; S3: After the device has been running for a period of time, when the adsorption blade 19 is covered with dust and the adsorption capacity decreases, the operator controls the compressor unit 10, the electric valve a9, and the electric valve b13 to be closed, and controls the electric valve c23, the electric valve d25, the electric valve e27, and the electric valve f31 to be opened through the controller 2; S4: Use the controller 2 to control the compressed gas tank 11 to supply gas to the cleaning water tank 20 through the bypass air pipe 24. The water in the cleaning water tank 20 generates water mist under pressure and is sprayed out from the nozzle 15 in the ring pipe 14, so that the water mist drives the power fan 16 and the dust suppression mechanism 4 to rotate, flushing and cleaning the blades of the power fan 16 and the blades of the adsorption blade 19; S5: After the device has finished automatic cleaning, when it is necessary to recycle the sewage for use, the valve on the sewage discharge pipe 33 can be opened to transfer the recycled sewage. When the device is idle, the clean water in the clean water tank 20 can be replenished to the water supply point through the water supply pipe 21.
