[0002] With the development of China's economy, the demand for resources such as coal and metals is increasing. Shallow resources have basically been exhausted, and underground mining needs to be further transferred to deeper depths. However, with the increase in mining depth, the formation temperature also increases accordingly, resulting in the problem of high temperature in the working environment during underground resource mining; especially in the roadway driving face with poor ventilation underground, the heat of rocks and working face equipment cannot be taken away in time, resulting in a high temperature of up to 40 °C in the driving face, seriously exceeding the specified value of the national standard. The process of underground mining involves a large amount of blasting, crushing, etc. of coal and rock, which will generate a large amount of coal and rock dust and gun smoke. And underground mining is carried out in a relatively closed space, and only ventilation can be relied on to take away the dust and gun smoke generated during working face mining. For the poor ventilation during the driving of a dead-end roadway, a large amount of coal and rock dust and gun smoke generated in the driving face cannot be taken away in time, resulting in a serious excess of the dust concentration in the working face and the gun smoke concentration can only reach the specified situation of the national standard.

The present invention uses the ventilation system to provide the power and channel for the flow of air, so that the air flow in the roadway driving face passes through the dust removal and cooling system to achieve the effects of four-stage dust removal and two-stage cooling, and can cooperate with a dust suppressant to further enhance the dust removal effect, and at the same time realize the function of recycling sewage. Then, the water contained in the air flow is further removed through the condenser. Then, the activated carbon adsorption system is used to purify the harmful gases insoluble in water in the air flow. Finally, the purified air flow is sent to the working face. The present invention can effectively reduce the air temperature, dust and gun smoke concentration in the driving face on the return air side, reduce the harm to the human body, and can be combined with the track in the roadway through the base system, so that the whole device can move on the mine car track in the roadway, and is convenient to use.

[0016] The present invention has the following beneficial effects: 1. The ventilation and cooling system for the underground roadway of the mine adsorbs and treats toxic and harmful gases in the underground air by setting up a filter box. At the same time, it sprays and cools the underground air by setting up a spray component, and finally ventilates the purified air to ensure the underground air quality and the operation safety. 2. The ventilation and cooling system for the underground roadway of the mine sets up a fan component. The water flow with a certain water pressure impacts the baffle, and the baffle can drive the lever to rotate a certain angle. Then, the lever drives the connecting rod and the fan board at one end of the connecting rod to swing in the air, fanning the surrounding air, as much as possible ensuring the spraying range, so that the underground air is evenly sprayed, and accelerating the underground cooling efficiency. 3. The ventilation and cooling system for the underground roadway of the mine sets up a flip - type water baffle.

The water baffle is symmetrically and horizontally arranged, and a flow - guiding plate is arranged on the water baffle, so that the water flow from the spray flows onto the water baffle. When the water volume is greater than the torsion force of the torsion spring, the water baffle flips along the fixed rod, and the water flow impacts downwards and enters the collection box through the filter plate. Using the water flow impact force, the water flow through the filter plate is effectively increased. 4. The ventilation and cooling system for the underground roadway of the mine successively sets a pull rod and a winding shaft between the flow - guiding plate and the feeding plate. After the water flow flows out, the water baffle resets, the traction rope loosens, and the spring in the pull rod drives the feeding plate to reset. Repeating like this can scrape the surface of the filter plate to avoid the blockage of the pull rod. 5. The ventilation and cooling system for the underground roadway of the mine sets up a push rod on one side of the flow - guiding plate. When the fan board swings and presses down one end of the push rod, since the push rod is rotationally connected to one side of the collection box through a torsion spring shaft, the other end of the push rod rises, thereby knocking on the flow - guiding plate, and being able to knock off the impurities remaining on the water baffle to prevent too many impurities from affecting the horizontal balance force provided by the torsion spring for the water baffle, thus affecting the water storage capacity of the two groups of water baffles in the initial state, and avoiding affecting the impact force of the collected water flow.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment, please refer to Figures 1 to 11, the present invention discloses a ventilation and cooling system for underground mine roadways, including a movable bottom plate 8 and a spraying assembly arranged on the bottom plate 8. A filter box 1 is arranged on the bottom plate 8, and a gravity sensor 4 is connected between the filter box 1 and the bottom plate 8. One side bottom of the filter box 1 is communicated with an air suction nozzle 2, and the top of the filter box 1 is communicated with an air outlet 3. The air outlet direction of the air outlet 3 faces the spraying assembly. A first adsorption plate 5, a second adsorption plate 6 and a third adsorption plate 7 are sequentially arranged in the filter box 1, and the first adsorption plate 5, the second adsorption plate 6 and the third adsorption plate 7 are arranged in an equidistant array.

[0030] In this embodiment, a first adsorption plate 5, a second adsorption plate 6 and a third adsorption plate 7 arranged in an equidistant array are sequentially arranged in the filter box 1. The first adsorption plate 5, the second adsorption plate 6 and the third adsorption plate 7 are respectively set as a high-efficiency dust removal filter screen, an activated carbon filter element and a PP cotton filter element to filter and adsorb toxic and harmful substances in the underground air. The underground air enters through the air suction nozzle 2, passes through the filtration of the first adsorption plate 5, the second adsorption plate 6 and the third adsorption plate 7 from bottom to top, and then is discharged through the air outlet 3. An air suction fan is arranged between the air outlet 3 and the filter box 1.

[0031] It should be noted that a gravity sensor 4 is arranged at the bottom of the filter box 1. After the first adsorption plate 5, the second adsorption plate 6 and the third adsorption plate 7 adsorb a certain mass of impurities, the signal of the gravity sensor 4 is fed back to remind the operator to clean / replace the first adsorption plate 5, the second adsorption plate 6 and the third adsorption plate 7.

[0032] A water tank 9 is arranged on one side of the filter box 1. A water pump 10 is arranged on the top of the water tank 9. The water tank 9 and the spraying assembly are communicated. The spraying assembly includes a water supply pipe 11 communicated with both sides of the water tank 9. A spraying pipe 12 is communicated between the two groups of water supply pipes 11. A spraying nozzle 14 is communicated below the spraying pipe 12. A pressure increasing valve 13 is arranged in the spraying nozzle 14. A supporting leg 16 is arranged at the bottom of the water supply pipe 11.

[0033] In this embodiment, a water tank 9 is arranged. Ice cubes are filled at the bottom of the water tank 9. The water tank 9 is filled with sufficient water. A pipeline for regularly throwing ice cubes is arranged on one side of the water tank 9. The water pump 10 is started, so that the water flows through the water supply pipe 11 and enters the spraying pipe 12, and then is sprayed through the pressure increasing valve 13 and the spraying nozzle 14 to cool down the underground control.

[0034] It should be noted that the spraying assembly is supported by the supporting legs 16 to ensure the stability of the spraying structure.

[0035] On both sides of the spray assembly, there are symmetrically arranged air - fanning assemblies. When the spray assembly works, the air - fanning assemblies are affected by the water flow and generate swings. The air - fanning assembly includes a sleeve 20 arranged on the outer wall of the water supply pipe 11. On one side of the sleeve 20, there is a hollow plate 21. The hollow plate 21 is successively and penetratively arranged with the water supply pipe 11 and the sleeve 20. A lever 22 is movably arranged in the hollow plate 21. One end of the lever 22 is provided with a connecting rod 26, and the connecting rod 26 extends outside the hollow plate 21 and is connected with a fanning plate 18.

[0036] In this embodiment, a baffle 19 is movably arranged in the water supply pipe 11. A sleeve 20 is sleeved outside the moving position of the baffle 19. One side of the sleeve 20 is communicated with a hollow plate 21. A lever 22 is arranged in the hollow plate 21. One end of the lever 22 is connected with a connecting rod 26, and a fanning plate 18 is arranged on the surface of the connecting rod 26. When the water flow is pressed into the water supply pipe 11 by the water pump 10, it will impact the baffle 19. The baffle 19 can drive the lever 22 to rotate by a certain angle, thereby using the lever 22 to drive the connecting rod 26 and the fanning plate 18 at one end of the connecting rod 26 to swing in the air, fan the surrounding air, as much as possible to ensure the spraying range, and uniformly spray - process the air in the mine, accelerating the cooling efficiency in the mine.

[0037] It should be noted that during use, the water pump 10 is started. The water pressure of the water pump 10 can be set in an alternating large - small mode, which is achieved by using two pressure switches. One is set with a larger pressure value to control the stop of the water pump 10, and the other is set with a smaller pressure value to control the start of the water pump 10. With such a setting, the water pressure will change within a fluctuation range, thereby avoiding frequent start - up of the water pump 10 and maintaining stable water pressure. A second pin shaft 24 is fixedly connected in the hollow plate 21. The water supply pipe 11 is provided with a baffle 19. The baffle 19 is fixedly connected with the lever 22. The lever 22 is rotationally connected with the second pin shaft 24. One end of the lever 22 is pin - connected with a sealing plate 25 through a first pin shaft 23. The hollow plate 21 is provided with a sliding groove at the position where the connecting rod 26 penetrates. The sealing plate 25 is in fit with the sliding groove, and the sealing plate 25 is slidably connected with the sliding groove.

[0038] In this embodiment, a second pin shaft 24 is arranged in the hollow plate 21. The lever 22 can swing under the action of external force by being pin - connected with the second pin shaft 24. A sealing plate 25 is pin - connected at the end of the lever 22 far from the baffle 19. The sealing plate 25 is slidably connected to the inner wall of the hollow plate 21. The sealing plate 25 is in fit with the inner wall of the hollow plate 21 and slides in fit with the inner wall of the hollow plate 21 following the swing of the lever 22. It can not only drive the fanning plate 18 to fan the air outside, but also use the sealing plate 25 to block the sliding groove to avoid water leakage, ensure the spraying effect of the spray nozzle 14, and ensure the cooling effect of the air in the mine.

[0039] The collection component is arranged below the spraying component, and the water flow generated by spraying flows into the collection component; the collection component includes a collection tank 17, a filter plate 27 is arranged in the collection tank 17, and one side of the bottom of the collection tank 17 is communicated with a return water pipe 15, and the return water pipe 15 is communicated with the bottom of the water tank 9.

[0040] In this embodiment, a collection tank 17 is arranged below the spray pipe 12 to collect the water flow after spraying, and the filter plate 27 is used to filter it. The filtered purified water is then recycled into the water tank 9 through the return water pipe 15 to repeatedly spray and cool the underground air.

[0041] A filter component is arranged in the collection component. After the sprayed water flow in the collection component passes through the filter component, it flows into the water tank 9 through a pipeline. The filter component includes two groups of water baffle plates 28 symmetrically arranged in the collection tank 17. One side of the bottom of the water baffle plate 28 is connected with a limiting plate 29, and the limiting plate 29 is attached to the upper surface of the filter plate 27. Two groups of connecting seats 34 are symmetrically arranged on the water baffle plate 28. A fixing rod 30 is arranged between the two groups of connecting seats 34. Both ends of the fixing rod 30 are fixedly connected to the inner wall of the collection tank 17. A torsion spring 33 is arranged between the connecting seat 34 and the fixing rod 30. One side of the water baffle plate 28 is connected with a diversion plate 32.

[0042] In this embodiment, to ensure the filtering effect, two groups of water baffle plates 28 are symmetrically arranged on the collection tank 17. Two groups of connecting seats 34 are arranged on the water baffle plate 28. A torsion spring 33 is arranged in the connecting seat 34. A fixing rod 30 passes through the connecting seat 34. The water baffle plate 28 is hoisted by the fixing rod 30. Under the action of the torsion spring 33, in the initial state, the water baffle plates 28 are symmetrically and horizontally arranged, and a diversion plate 32 is arranged on the water baffle plate 28, so that the sprayed water flow flows onto the water baffle plate 28. When the water volume is greater than the torsion force of the torsion spring 33, the water baffle plate 28 flips along the fixing rod 30. After the two groups of water baffle plates 28 flip, the water flow impacts and then enters the collection tank 17 through the filter plate 27.

[0043] Specifically, if the sprayed water flow directly falls into the collection tank 17 through the filter plate 27, the filter plate 27 will be blocked in the long run. With the above structure, the water flow impact force can pass through the filter plate 27, thereby effectively increasing the water flow through the filter plate 27.

[0044] There are two groups of material pushing plates 35 symmetrically arranged above the water baffle 28. The material pushing plates 35 slide between the water baffle 28 and the filter plate 27, and through holes 36 are formed in the material pushing plates 35. On one side of the material pushing plates 35, there are two groups of pull rods 37 with springs symmetrically arranged. The two groups of pull rods 37 extend outside the collection box 17, and a connecting plate 38 is connected between the two groups of pull rods 37. A winding shaft 41 is rotatably arranged on one side of the connecting plate 38. On one side of the guide plate 32, there are two groups of ear plates 31, and a traction shaft 39 is rotatably connected between the two groups of ear plates 31. A traction rope 40 is connected between the traction shaft 39 and the winding shaft 41.

[0045] In this embodiment, a material pushing plate 35 is arranged between the water baffle 28 and the filter plate 27, and a through hole 36 is arranged in the material pushing plate 35. The through hole 36 can not only ensure the flow of water, but also block some large-particle impurities. After the water filtered through the impurities passes through the filter plate 27, the purity is higher. The recovery purity of the sprayed water is improved, and the spraying effect is further improved.

[0046] Specifically, when the water baffle 28 is turned downward, it can drive the guide plate 32 to load the sample, and the pull rod 37 is pulled by the traction rope 40 to continue to extend outside the collection box 17. When the water flows out, the water baffle 28 resets, the traction rope 40 loosens, and the spring in the pull rod 37 drives the material pushing plate 35 to reset. Repeating like this can scrape the surface of the filter plate 27 to avoid blockage of the pull rod 37.

[0047] On one side wall of the collection box 17, there are two groups of mounting seats 45. A torsion spring shaft 44 is arranged between the mounting seats 45. A top rod 42 is connected to the surface of the torsion spring shaft 44. The top rod 42 is arranged in a U shape, and knocking blocks 43 are connected to both ends of the top rod 42. The knocking blocks 43 are arranged in a fitting manner with the bottom surface of the fan plate 18.

[0048] In this embodiment, a top rod 42 is arranged on one side of the guide plate 32. The top rod 42 is arranged in a U-shaped structure, and knocking blocks 43 are arranged at both ends of the top rod 42. One end of which is in contact with the bottom of the fan plate 18 in the initial state. During the swinging process of the fan plate 18, by pressing down one end of the top rod 42, the other end of the top rod 42 is lifted, so as to knock the guide plate 32. Since the guide plate 32 and the water baffle 28 are integrally arranged, that is, the impurities remaining on the water baffle 28 can be knocked off, preventing too many impurities from affecting the horizontal balance force provided by the torsion spring 33 for the water baffle 28, thereby affecting the water storage capacity of the two groups of water baffles 28 in the initial state, and finally affecting the impact force of the collected water flow.

Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0050] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
