Description

Technical Field

[0001] The invention relates to the technical field of mine ventilation, and in particular to a mine ventilation, cooling and dust removal device. Background Art

[0002] In mining operations, ventilation, cooling and dust removal play a vital role. A good ventilation system can effectively exhaust the dirty air underground, introduce fresh air, create a suitable breathing environment for workers, and reduce health risks caused by poor air quality. The cooling function helps to regulate the excessively high temperature underground, avoid equipment failures caused by high temperature and workers' heat stroke, and improve operational safety and efficiency. Efficient dust removal measures can reduce dust wear on equipment, extend equipment service life, and greatly reduce the potential risk of dust explosions, ensuring the safe and stable operation of mine production.

[0003] However, the currently used mine ventilation, cooling and dust removal devices have many obvious defects. On the one hand, most devices adopt a fixed setting method. As the mining process continues to advance, it is impossible to automatically adjust the blowing and suction positions according to the mining progress. This makes it difficult to always maintain the blowing and suction positions at the most suitable locations, greatly weakening the actual effect of ventilation, cooling and dust removal. For example, when the mining area gradually goes deeper, the fixed vents may not be able to accurately deliver fresh air to the working surface, resulting in excessively high temperatures and dust accumulation on the working surface, affecting the operating environment and health of the workers. On the other hand, during the mining of the mine, a large amount of dust generated on the working surface will spread around without hindrance, and then spread to the entire mine. This will not only seriously affect the air quality in other areas of the mine, but also damage the health of all workers in the mine. In such an environment for a long time, workers are very likely to suffer from respiratory diseases such as pneumoconiosis, which poses a great threat to their health. Summary of the invention

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] In order to solve the technical problems in the prior art that the ventilation, cooling and dust removal devices cannot automatically adjust the blowing and suction positions according to the progress of mining, and the dust on the working surface easily spreads to the entire mine tunnel, affecting the air quality and the health of workers, the present invention provides a mine ventilation, cooling and dust removal device, which can automatically adjust the blowing and suction positions according to the progress of mining, so that the ventilation position can always be maintained at a suitable position, and at the same time can prevent the dust on the working surface from spreading to the entire mine tunnel.

[0037] See also Figure 1 and Figure 2 , Figure 1 It is a structural schematic diagram of a mine ventilation, cooling and dust removal device in one embodiment of the present invention. The mine ventilation, cooling and dust removal device includes a pipeline mechanism 1, a moving mechanism 2, a blower mechanism 3, a suction mechanism 4, a detection mechanism 5, a fresh air mechanism 6 and an exhaust mechanism 7.

[0038] The pipeline mechanism 1 includes an air inlet pipe group 11 and an air outlet pipe group 12 fixed to the top surface of the mine tunnel 8.

[0039] The fixed end of the moving mechanism 2 is fixed to the air inlet pipe group 11 or the air outlet pipe group 12 , and the movable end of the moving mechanism 2 can move along the extension direction of the mine tunnel 8 .

[0040] The air blowing mechanism 3 is installed at the movable end of the mobile mechanism 2, and the air blowing mechanism 3 includes an air curtain piece 31 and an air blowing piece 32 connected to one end of the air inlet pipe group 11. The outlet of the air curtain piece 31 is set downward, and the outlet of the air blowing piece 32 is set toward the working surface in the mine tunnel 8.

[0041] The suction mechanism 4 includes a suction hood 41 , which is fixed to the movable end of the moving mechanism 2 . The suction hood 41 is disposed obliquely above the working surface, and is connected to one end of the air outlet pipe group 12 .

[0042] The detection mechanism 5 includes a distance detection member 51, and the distance detection member 51 is used to detect the lateral distance between the suction hood 41 and the working surface.

[0043] The outlet of the fresh air mechanism 6 is communicated with the other end of the air inlet pipe group 11 .

[0044] The inlet of the exhaust mechanism 7 is communicated with the other end of the air outlet pipe group 12 .

[0045] In the technical solution provided by the present invention, the mobile mechanism 2 can automatically adjust the positions of the blowing mechanism 3 and the suction mechanism 4 according to the lateral distance between the suction hood 41 and the working surface monitored by the distance detection component 51, so that the blowing and suction positions are always maintained at the most appropriate positions, greatly improving the ventilation, cooling and dust removal effects. Compared with the traditional fixed device, it can ensure that the working surface can be accurately ventilated, dusted and cooled at different mining stages; at the same time, the wind curtain component 31 forms a wind curtain behind the working surface, preventing the dust on the working surface from spreading to other areas of the mine tunnel 8 from the source, ensuring the air quality of other areas in the mine tunnel and reducing damage to the health of workers. The suction hood 41 can cooperate with the blowing component 32 to promptly absorb the dust on the working surface and the surrounding area, further reducing the diffusion range of dust in the mine tunnel.

[0046] In one embodiment, see Figure 1 and Figure 2 The air outlet pipe group 12 includes a plurality of air outlet pipe sections 121 which are detachably connected end to end, and at least one fixing rod 1211 is fixed on the side wall of each air outlet pipe section 121, and the fixing rod 1211 is used to be fixed to the inner top surface of the mine tunnel 8. When the mining progress exceeds the length of a single air outlet pipe section 121, the staff can easily install a new air outlet pipe section 121, so that the entire air outlet pipe group 12 can closely follow the mining progress and continuously and efficiently play its role in the ventilation, cooling and dust removal system.

[0047] In one embodiment, see Figure 1 and Figure 2The air inlet pipe group 11 includes a plurality of air inlet pipe sections 111 which are detachably connected end to end, and the air inlet pipe sections 111 correspond to the air outlet pipe sections 121 one by one. At least one first connecting rod 1111 is fixed on the side wall of each air inlet pipe section 111, and the first connecting rod 1111 is fixed to the corresponding air outlet pipe section 121. When the mining progress exceeds the length of a single air inlet pipe section 111, the staff can easily install a new air inlet pipe section 111, so that the entire air inlet pipe section 111 can closely follow the mining progress and continuously and efficiently play its role in the ventilation, cooling and dust removal system.

[0048] In one embodiment, see Figure 1-Figure 4 The moving mechanism 2 includes a transverse plate 21, two mounting plates 22, a screw rod 23, a nut 24, a guide rod 25, a fixing plate 26 and a motor 27. The transverse plate 21 can be detachably fixed to any of the air inlet pipe sections 111. The two mounting plates 22 are respectively fixed to the two ends of the transverse plate 21. A guide hole is opened on one of the mounting plates 22. The two ends of the screw rod 23 are respectively rotatably arranged on the two mounting plates 22. The nut 24 is threadedly sleeved on the screw rod 23. The guide rod 25 is fixed to the nut 24 and is parallel to the screw rod 23. The guide rod 25 is slidably inserted into the guide hole. The fixing plate 26 is fixedly connected to the nut 24 and the guide rod 25. The hair dryer mechanism 3 is installed on the fixing plate 26. The motor 27 is connected to the screw rod 23 and is used to drive the screw rod 23 to rotate.

[0049] In this embodiment, the motor 27 is connected to the screw rod 23, and the motor 27 can drive the screw rod 23 to rotate after it is started. The nut 24 is threadedly sleeved on the screw rod 23. According to the principle of threaded transmission, when the screw rod 23 rotates, the nut 24 will move along the axial direction of the screw rod 23. Since the guide rod 25 is fixed to the nut 24 and parallel to the screw rod 23, and the guide rod 25 is slidably inserted into the guide hole on the mounting plate 22, the nut 24 is limited to linear motion along the direction of the screw rod 23, which prevents the nut 24 from rotating or deflecting during the movement, and ensures the stability and accuracy of the movement. The fixed plate 26 is fixedly connected to the nut 24 and the guide rod 25, so that the fixed plate 26 can move stably with the nut 24, thereby driving the blower mechanism 3 installed on the fixed plate 26 to achieve automatic movement, meeting the demand for ventilation position adjustment when the mining progress changes.

[0050] In one embodiment, see Figure 2 and Figure 4At least two second connecting rods 1112 are fixed on the air inlet pipe section 111, and a quick-insertion female head 1113 is fixed on the second connecting rod 1112; the mobile mechanism 2 also includes a quick-insertion male head 28 that cooperates with the quick-insertion female head 1113, and the quick-insertion male head 28 is used to be inserted into the quick-insertion female head 1113. The quick-insertion male head 28 and the quick-insertion female head 1113 are used in conjunction with each other, which greatly improves the installation efficiency. When installing the mobile mechanism 2, the staff only needs to align the quick-insertion male head 28 with the quick-insertion female head 1113 of the second connecting rod 1112 on the air inlet pipe section 111 and insert it to quickly complete the connection without complicated tools or cumbersome installation steps. Similarly, when the equipment is maintained, parts are replaced, or the position needs to be readjusted, the quick-insertion male head 28 can also be quickly pulled out from the quick-insertion female head 1113 to achieve rapid disassembly, which greatly shortens the equipment downtime and improves the overall efficiency of mining operations.

[0051] In one embodiment, see Figure 2 and Figure 5 The blower mechanism 3 further includes a connecting tee 33, which is mounted on the fixing plate 26. The first interface of the connecting tee 33 is detachably connected to the air inlet pipe section 111 closest to the air outlet end via a first hose 34. The second interface of the connecting tee 33 is connected to the inlet of the blowing member 32 via a vertical pipe 35. The third interface of the connecting tee 33 is connected to the inlet of the air curtain member 31 via a second hose 36. In this embodiment, the setting of the connecting tee 33 realizes the efficient distribution of the gas transported from the air inlet pipe section 111. Through its three interfaces, the gas is respectively directed to the blowing member 32 and the air curtain member 31. Among them, the second interface is connected to the blowing member 32 via a vertical pipe 35, so that the gas can be accurately blown to the working surface in the mine tunnel 8, which plays a role in cooling and blowing away dust; the third interface is connected to the air curtain member 31 through the second hose 36, and the gas is blown downward from the outlet of the air curtain member 31 to form a wind curtain above the working surface, effectively preventing dust from spreading to the surroundings. This reasonable gas distribution method improves the pertinence and effectiveness of the ventilation, cooling and dust removal device in regulating the working surface environment.

[0052] In one embodiment, see Figure 2The blowing mechanism 3 also includes an angle adjusting member 37, which is used to adjust the angle between the vertical pipe 35 and the fixed plate 26. The angle adjusting member 37 includes a rotating rod 371 and an adjusting cylinder 372. One end of the rotating rod 371 is rotatably connected to the fixed plate 26, and the other end of the rotating rod 371 is fixedly connected to the vertical pipe 35. One end of the adjusting cylinder 372 is hinged to the fixed plate 26, and the other end of the adjusting cylinder 372 is hinged to the rotating rod 371. The situation of the mining operation surface is complex and changeable. Different mining stages and operation modes have different requirements for the blowing angle. The setting of the angle adjusting member 37 enables the angle between the vertical pipe 35 and the fixed plate 26 to be flexibly adjusted. When the height, slope, etc. of the mining operation surface changes, the staff can change the angle between the rotating rod 371 and the fixed plate 26 by controlling the extension and contraction of the adjusting cylinder 372, thereby driving the vertical pipe 35 to rotate, so that the blowing angle of the blowing member 32 can be accurately aligned with the operation surface.

[0053] In one embodiment, see Figure 2 The air suction mechanism 4 further includes a third connecting rod 42 , one end of the third connecting rod 42 is fixed to the air suction hood 41 , and the other end of the third connecting rod 42 is detachably fixed to the fixing plate 26 .

[0054] In one embodiment, see Figure 1-Figure 7 , the detection mechanism 5 also includes a dust concentration sensor 52, which is installed in the suction hood 41; the fresh air mechanism 6 includes a blower 61, a filter box 62 and a first pipe 63, the outlet of the blower 61 is connected to one end of the filter box 62, the other end of the filter box 62 is connected to one end of the first pipe 63, and the other end of the first pipe 63 is connected to the air inlet pipe section 111; the exhaust mechanism 7 includes an exhaust fan 71, a dust collector 72 and a second pipe 73, the inlet of the exhaust fan 71 is connected to the outlet of the dust collector 72, the inlet of the dust collector 72 is connected to one end of the second pipe 73, and the other end of the second pipe 73 is connected to the air outlet pipe section 121. In this embodiment, when the dust concentration detected by the dust concentration sensor 52 increases, the blower 61 and the exhaust fan 71 increase the output power, and vice versa, the output power is reduced. The output power of the blower 61 and the exhaust fan 71 is dynamically adjusted according to the detection result of the dust concentration sensor 52, thus avoiding energy waste caused by continuous high-power operation of the equipment. When the dust concentration is low, the equipment power is reduced to reduce energy consumption; when the dust concentration increases, the power is increased in time to respond, ensuring that the ventilation and dust reduction needs are met while achieving efficient energy utilization, thus reducing the operating costs of mining.

[0055] In one embodiment, see Figure 1-Figure 7 , the detection mechanism 5 also includes a temperature sensor 53, and the fresh air mechanism 6 also includes a refrigerator 64, and the refrigerator 64 is used to cool the gas in the filter box 62. The temperature sensor 53 monitors the temperature condition in the mine tunnel in real time, and once it detects that the temperature exceeds the appropriate range, it will feedback the signal. The refrigerator 64 in the fresh air mechanism 6 is then started to cool the gas in the filter box 62. The refrigerated gas is transported to the mine tunnel through the air inlet pipe group 11, which effectively reduces the temperature of the working area, creates a cool and comfortable working environment for the staff, helps to improve the work efficiency of the staff, reduces fatigue and heat stroke caused by high temperature, and ensures the smooth progress of mining operations.

[0056] The detailed working process of the technical solution of the present invention is as follows:

[0057] (1) Introduction of fresh air: The blower 61 in the fresh air mechanism 6 is started to draw outside air into the filter box 62. After the impurities are filtered by the filter box 62, the gas enters the first pipe 63 and is finally transported to the mine tunnel 8 through the air inlet pipe group 11. If the fresh air mechanism 6 is equipped with a refrigerator 64, the refrigerator 64 will cool the gas in the filter box 62 to reduce the temperature of the air entering the mine tunnel 8, thus realizing the initial stage of ventilation and cooling.

[0058] (2) Blowing: The air in the air inlet pipe group 11 can pass through the connecting tee 33, enter the blowing member 32 through the first hose 34 and the vertical pipe 35, and enter the wind curtain member 31 through the second hose 36. The outlet of the wind curtain member 31 blows out air downward, forming a wind curtain behind the working surface to prevent the dust on the working surface from spreading to the surroundings; the outlet of the blowing member 32 faces the working surface, and the blown air cools the working surface and blows away the accumulated dust, making it easier to collect. The angle adjustment member 37 can change the angle of the rotating rod 371 by adjusting the extension and contraction of the cylinder 372, and then adjust the angle between the vertical pipe 35 and the fixed plate 26, that is, adjust the blowing angle of the blowing member 32 to adapt to different working surface conditions.

[0059] (3) Suction and dust removal: The dust generated on the working surface and the dust blown away by the blowing member 32 enter the exhaust mechanism 7 through the air outlet pipe group 12 under the suction force of the suction hood 41. The exhaust fan 71 in the exhaust mechanism 7 draws the dust-containing air sucked by the suction hood 41 into the dust collector 72. After being purified by the dust collector 72, the clean air is discharged from the mine tunnel 8 through the second pipe 73.

[0060] (4) Automatic following: The distance detection component 51 continuously monitors the lateral distance between the suction hood 41 and the working surface. After processing, the distance detection data can be converted into the distance between the entire device and the working surface. The mobile mechanism 2 receives the detection result of the distance detection component 51. When it detects that the lateral distance between the suction hood 41 and the working surface exceeds the preset range, the mobile mechanism 2 automatically starts. The motor 27 drives the screw rod 23 to rotate, driving the fixed plate 26 to move along the extension direction of the mine tunnel 8 until the lateral distance between the suction hood 41 on the fixed plate 26 and the working surface returns to within the preset range.

[0061] The beneficial effects of the technical solution provided by the present invention are as follows:

[0062] (1) Automatically follow the mining progress: The mobile mechanism 2 can automatically adjust the positions of the blowing mechanism 3 and the suction mechanism 4 according to the lateral distance between the suction hood 41 and the working surface monitored by the distance detection member 51, so that the blowing and suction positions are always maintained at the most appropriate positions, greatly improving the ventilation, cooling and dust removal effects. Compared with the traditional fixed device, it can ensure that the working surface can be accurately ventilated, dusted and cooled at different mining stages.

[0063] (2) Effectively control the spread of dust: The wind curtain member 31 forms a wind curtain behind the working surface, preventing the dust on the working surface from spreading to other areas of the mine tunnel 8 from the source, ensuring the air quality in other areas of the mine tunnel and reducing damage to the health of workers. The suction hood 41 can cooperate with the blowing member 32 to promptly absorb the dust on the working surface and the surrounding area, further reducing the spread of dust in the mine tunnel.

[0064] (3) Comprehensive environmental regulation: The fresh air mechanism 6 introduces fresh air and realizes the cooling function through the refrigerator 64, providing a comfortable air environment in the mine tunnel; the exhaust mechanism 7 effectively discharges dusty air and purifies the air in the mine tunnel; the detection mechanism 5 monitors parameters such as dust concentration and temperature in real time, providing support for the intelligent operation and precise control of the entire device.

[0065] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
