Description

Technical Field

[0001] The invention belongs to the technical field of mine ventilation, in particular to a mine ventilation device. Background Art

[0002] There are three types of uses for ventilators: main fans are used for ventilation of the entire mine or a wing of a mine, also called main fans; auxiliary fans are used for regulating the air volume in branch air ducts in mine ventilation ducts, and assist the main fans in their work; local fans are used for ventilation of local locations in mines where there is no through-flow and no tunnels are opened; mineral resource mining refers to the mining of solid metal and non-metallic deposits, including surface ore outcrops and open-pit mining of shallow ore bodies and underground mining of blind mines and deep ore bodies, extracting useful components from the mined ore or the ore itself has some kind of utilizable properties. Minerals can be divided into metallic minerals and non-metallic minerals according to the components contained in the ore.

[0003] In the current existing technology, when mining is carried out, air is transported to the mining face by setting up ventilation lanes, and during the air flow, harmful gases and smoke at the bottom of the mine are transported to the return air lane for centralized treatment. However, as the depth of the mine continues to extend, it is necessary to lengthen the ventilation duct inside the mine so that the exhaust gas inside the mine can be extracted and discharged in time. However, the surface of the ventilation pipe will be fixedly installed on the inner wall of the mine. Since the pipe used for ventilation is relatively long and the surface of the ventilation pipe is made of metal, the ventilation pipe is very heavy as a whole. When docking, a crane or a forklift is used to lift the ventilation pipe at the same time. However, when this large machine lifts the pipe, it lifts it with a chain. The lifting of the chain is not fine enough to make the pipe at the same level as the previous pipe. It is easy for the pipes to deviate, resulting in the inability to fix the screws at the joint of the ventilation pipe.

[0004] To this end, the present invention provides a mine ventilation device. Summary of the invention

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. A mine ventilation device described in the present invention overlaps one of the mine ventilation pipes on the top surface of the support pad, and at the same time, the bottom surface of one end of the convex sleeve is overlapped on the surface of the pushing plate to limit the position of the mine ventilation pipe, and the movable frame is moved to the bottom surface of the rearmost mine ventilation pipe so that the movable frame is perpendicular to the bottom edge position of the mine ventilation pipe, and the two pairs of semicircular support platforms are extended and lifted in cooperation with hydraulic rods so that the semicircular support platforms are overlapped on the bottom surface of the mine ventilation pipe, and the one pair of docking limit plates are lifted in cooperation with hydraulic rods and the top surface of the docking limit plates are sleeved on the inner wall surface of the limit slide groove, and then the slider is moved to one side by the threaded rod and the docking limit plate on the top surface of the hydraulic rod is slid on the bottom surface of the swing arm plate, and the swing arm plate is made to be at the junction of the swing arm plate and the semicircular support platform. The center point swings the swing arm plate upward and tilts it, and then lifts it through the hydraulic rod. As the swing arm plate is continuously lifted, the swing arm plate and the mine ventilation pipe are at the same horizontal height, and then the mine ventilation pipe on the top surface of the support pad is fitted and docked with one end of the mine ventilation pipe that needs to be docked, and then the mine ventilation pipe on the top surface of the support pad is pushed by the push plate to dock and fit the two mine ventilation pipes, so as to swing and lift the ventilation pipe, so that the horizontal height of the docking pipe and the pipe that needs to be docked is adjusted, and the screws between the two ventilation pipes cannot be effectively docked due to a slight tilt angle of the ventilation pipe when docking the ventilation pipe, and the bolts cannot pass through the slots of the flange on the surface of the ventilation pipe due to the tilt of the ventilation pipe, so that the joint of the ventilation pipe will have the effect of gas leakage due to insufficient fit;

[0018] 2. A mine ventilation device described in the present invention, when two mine ventilation pipes are butt-jointed, the mine ventilation pipe on the top surface of the supporting pad is first attached to the surface of one end of the mine ventilation pipe that needs to be butt-jointed, and when the two mine ventilation pipes are attached, the pushing plate is used to push one end of the mine ventilation pipe, and when the mine ventilation pipe on the top surface of the supporting pad is pushed by the pushing plate, the butt-jointing groove on the surface of one end of the mine ventilation pipe is butt-jointed with the butt-jointing strip on the surface of the other mine ventilation pipe, and the butt-jointing between the butt-jointing strip and the butt-jointing groove is utilized to butt-join the two mine ventilation pipes. The joint between the two mine ventilation pipes is sealed to prevent gas leakage. At the same time, when the butt joint groove and the butt joint strip are butt jointed, the butt joint rod on the surface of one side of the convex sleeve is sleeved into the inside of the butt joint hole, and the multiple butt joint rods on the surface of one side of the convex sleeve are used to support the position of the mine ventilation pipe to increase the stability of the mine ventilation pipe, so as to achieve the effect of sealing and compressive support for the butt joint between the two mine ventilation pipes, so as to prevent the mine ventilation pipe from falling slightly due to its own gravity, resulting in a gap at the butt joint of the mine ventilation pipe, and increase the compressive stability between the two mine ventilation pipes through the butt joint rod;

[0019] 3. The mine ventilation equipment described in the present invention cooperates with the air inlet to infuse the gas inside the mine ventilation pipe into the interior of the coal filter box, and cooperates with the partition to initially block the incoming gas. As the exhaust gas and coal dust continue to accumulate inside the coal filter box, the gas will spread toward the bottom of the inner side of the coal filter box. When the exhaust gas and coal dust pass over the inclined plate, the exhaust gas is mixed with the soaked clean water inside the coal filter box. The wet liquid is mixed with the coal particles inside the exhaust gas and coal dust. The soaked clean water is used to absorb the coal dust inside the exhaust gas and coal dust and adsorb it inside the soaked clean water. After filtering the coal dust, the gas will float upward, and then pass through the exhaust filter plate to discharge the exhaust gas After being released, the coal dust remains inside the soaked clean water, achieving the goal of using liquid to filter out the coal dust inside the exhaust gas coal dust, preventing the coal dust inside the exhaust gas from being discharged with the gas, and then causing the coal dust inside the exhaust gas to connect with the open space outside. The granular coal dust has a large contact area with the outside world, and the accumulated coal dust contains a lot of air. Under the external fire source, the coal dust is very likely to self-ignite, and at the same time, it also increases the burning power of the coal dust and increases the effect of the spontaneous combustion of the coal dust. At a later stage, the water valve head is opened to replace the soaked clean water inside the coal filter box, clean up the coal dust inside the soaked clean water, and use the soaked clean water to increase the wetting power of the coal dust and reduce the spontaneous combustion of the coal dust.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 8As shown, a mine ventilation device according to an embodiment of the present invention comprises a mine ventilation pipe 11 and a coal filter box 13 detachably mounted on the surface of one end of the mine ventilation pipe 11, a pipe lap platform 12 movably sleeved on the outer surface of the bottom of the mine ventilation pipe 11, a movable frame 14 movably overlapped on the bottom surface of the mine ventilation pipe 11, a lifting adjustment unit is arranged on the outer surface of the top of the movable frame 14, the lifting adjustment unit comprises a hydraulic rod 145 fixedly mounted on an edge position of one side of the top of the movable frame 14, a semicircular support platform 146 movably sleeved on the outer surface of the bottom of the mine ventilation pipe 11 is fixedly mounted on the top surface of the hydraulic rod 145, a swing arm plate 147 is swingably sleeved on the surface of one side of the semicircular support platform 146, and the swing arm plate A support pad 148 movably sleeved on the bottom outer surface of the mine ventilation pipe 11 is fixedly connected to the top surface of 147 and located at the edge position of one side. A limiting slide groove 149 is provided on the bottom surface of the swing arm plate 147. A pushing plate 1412 movably overlapped on the surface of one end of the mine ventilation pipe 11 is provided on the outer surface of one end of the swing arm plate 147. A threaded rod 141 is provided on the top surface of the mobile frame 14 and located at the edge position of one side of the hydraulic rod 2 145. A slider 142 is movably sleeved on the outer surface of the threaded rod 141. A hydraulic rod 143 is fixedly installed on the top surface of the slider 142. A docking limiting plate 144 movably sleeved on the inner wall of the limiting slide groove 149 is fixedly connected to the output end of the hydraulic rod 143.

[0032] When the lifting and adjusting unit provided by the present invention is in use, as the mine is continuously excavated and deepened, it is necessary to increase the length of the mine ventilation pipe 11. At this time, the alternative mine ventilation pipe 11 is overlapped on the top surface of the support pad 148, and the mine ventilation pipe 11 and the swing arm plate 147 are overlapped together in a relatively horizontal manner in cooperation with the support pad 148, so that the mine ventilation pipe 11 will not have unnecessary deflection. At this time, one end of the swing arm plate 147 will overlap on the top surface of the mine ventilation pipe 11 due to gravity, and the hydraulic rod 145, the swing arm plate 147 and the mobile frame 14 are in a triangular support form, and at the same time, the bottom surface of one end of the convex sleeve 111 is overlapped on the surface of the push plate 1412 to adjust the mine ventilation pipe 11. The position is limited, and the mobile frame 14 is moved to the bottom outer surface of the rearmost mine ventilation pipe 11, so that the mobile frame 14 is perpendicular to the bottom edge position of the mine ventilation pipe 11, and the hydraulic rod 145 is used to extend and lift the semicircular support platform 146 so that the semicircular support platform 146 overlaps and fits on the bottom surface of the mine ventilation pipe 11, and then the employees observe whether the inner wall of the semicircular support platform 146 is completely in contact with the bottom outer surface of the mine ventilation pipe 11. If the semicircular support platform 146 is not completely in contact with the surface of the mine ventilation pipe 11, the position of the mobile frame 14 is appropriately moved and adjusted until the mobile frame 14 is completely at the bottom edge position of the mine ventilation pipe 11. If the semicircular support platform 146 is completely When it is fully fitted on the bottom outer surface of the mine ventilation pipe 11, it can be said that the position of the movable frame 14 is completely on the bottom surface of the mine ventilation pipe 11, and there is no need to move the movable frame 14 any further. Then, the hydraulic rod 143 is used to lift the docking limit plate 144 and the top surface of the docking limit plate 144 is sleeved on the inner wall of the limit slide groove 149. Then, the slider 142 is moved to one side by the threaded rod 141. As the slider 142 continues to move, the docking limit plate 144 on the top surface of the hydraulic rod 143 will slide on the bottom surface of the swing arm plate 147, and the swing arm plate 147 will be centered on the joint between the swing arm plate 147 and the semicircular support platform 146 to move upward. The swing arm plate 147 is lifted by the hydraulic rod 143, and the swing arm plate 147 and the mine ventilation pipe 11 are at the same horizontal height as the swing arm plate 147 is lifted continuously, so that the mine ventilation pipe 11 on the top surface of the support pad 148 is fitted and docked with one end of the mine ventilation pipe 11 that needs to be docked, and then the mine ventilation pipe 11 on the top surface of the support pad 148 is pushed by the push plate 1412 to dock and fit the two mine ventilation pipes 11, so as to swing and lift the ventilation pipe, adjust the horizontal height of the docking pipe and the pipe that needs to be docked, and avoid the inability to effectively dock the screws between the two ventilation pipes due to a slight tilt angle of the ventilation pipe when docking the ventilation pipe.The inclination of the ventilation pipe will make it impossible for the bolts to pass through the slots of the flange on the surface of the ventilation pipe, so that the joint of the ventilation pipe will not fit tightly enough, resulting in gas leakage.

[0033] Furthermore, if Figure 1 - Figure 7 As shown, a downward pressure pad 1411 movably overlapped on the bottom surface of one end of the swing arm plate 147 is fixedly connected to the top surface of the mobile frame 14 and located at the edge position of one side, and a moving wheel 1410 is symmetrically arranged on the edge positions of both sides of the bottom of the mobile frame 14. A plurality of convex casings 111 are symmetrically fixedly installed on the outer surfaces of both ends of the mine ventilation pipe 11, and a docking groove 112 is opened on the outer surface of the convex casing 111 and located at the edge position of the surroundings, and a docking hole 113 is opened on the outer surface of the convex casing 111 and located at the inner edge position of the docking groove 112, and a surface of another convex casing 111 is provided with a docking hole 113. There is a docking strip 116 that is movably sleeved on the inner wall of the docking groove 112, a docking rod 115 that is movably sleeved inside the docking hole 113 is fixedly connected to the outer surface of the convex shell 111 and located on the inner edge of the docking strip 116, a one-way ventilation pipe 114 that extends to the inner wall of the mine ventilation pipe 11 is fixedly installed on the outer surface of one end of the mine ventilation pipe 11 and located on the outer surface of the convex shell 111, a ring 117 is fixedly installed on the inner wall of the mine ventilation pipe 11 and located on the edge of the entrance of the one-way ventilation pipe 114, and a mine exhaust fan 118 is arranged on the outer surface of the ring 117.

[0034] When the convex sleeve 111, the docking groove 112, the docking hole 113, the one-way ventilation pipe 114, the docking rod 115, the docking strip 116, the ferrule 117 and the mine exhaust fan 118 provided by the present invention are used, after the two mine ventilation pipes 11 are docked, the mine ventilation pipe 11 on the top surface of the supporting pad 148 is first attached to the surface of one end of the mine ventilation pipe 11 to be docked, and when the two mine ventilation pipes 11 are attached, the pushing plate 1412 is used to push one end of the mine ventilation pipe 11, and when the mine ventilation pipes 11 on the top surface of the supporting pad 148 are attached, the mine ventilation pipe 11 is first attached to the surface of one end of the mine ventilation pipe 11 to be docked. Under the push of the push plate 1412, the mine ventilation pipe 11 is connected with the docking groove 112 on one end surface of the mine ventilation pipe 11 and the docking strip 116 on the surface of the other mine ventilation pipe 11. The connection between the docking strip 116 and the docking groove 112 is used to seal the joint between the two mine ventilation pipes 11 to prevent gas leakage. At the same time, when the docking groove 112 and the docking strip 116 are docked, the docking rod 115 on one side surface of the convex sleeve 111 is sleeved into the inside of the docking hole 113, and the docking rod 115 on one side surface of the convex sleeve 111 is matched with the docking rod 116 on one side surface of the convex sleeve 111. A plurality of docking rods 115 support the position of the mine ventilation pipe 11 to increase the stability of the mine ventilation pipe 11, and achieve the sealing and pressure-resistant support of the docking point between the two mine ventilation pipes 11, so as to prevent the mine ventilation pipe 11 from falling slightly due to its own gravity, resulting in a gap at the docking point of the mine ventilation pipe 11. The docking rod 115 increases the pressure-resistant and stable force between the two mine ventilation pipes 11, and then the mine exhaust fan 118 on the inner wall of the ring 117 rotates and blows air inside the mine ventilation pipe 11, and cooperates with the mine exhaust fan 118 to blow air outside the mine ventilation pipe 11. The air from the outside is guided into the interior of the mine ventilation pipe 11. Since there is a mine exhaust fan 118 inside each mine ventilation pipe 11, the exhaust gas can flow continuously inside the mine ventilation pipe 11, providing a driving force for the continuous flow of gas. While the middle section of the mine ventilation pipe 11 is blowing, it cooperates with the one-way ventilation pipe 114 to absorb the air in the middle section of the mine into the interior of the mine ventilation pipe 11, and cooperates with the one-way ventilation pipe 114 to make the gas flow in one direction, and as the gas continues to flow, it is infused into the interior of the coal filter box 13.

[0035] Furthermore, if Figure 1 - Figure 4 and Figure 8As shown, an air inlet 131 is provided on the inner wall surface of the connection between the coal filter box 13 and the mine ventilation pipe 11, a partition 132 is fixedly connected to the top inner wall surface of the coal filter box 13 and located at the edge position of the air inlet 131, and an inclined plate 133 is provided on the bottom surface of the partition 132. The interior of the coal filter box 13 is filled with soaked clean water 134, an exhaust filter screen 136 is provided on the top surface of the coal filter box 13, and a water valve head 135 is provided on the other side surface of the coal filter box 13. Expansion bolt holes 121 are provided on the outer surface of the pipeline lap platform 12 and located at the upper and lower edge positions, a trapezoidal bar 122 is provided in the middle position of the pipeline lap platform 12 and located at the top edge position, and a lap platform plate 123 provided on the bottom outer surface of the mine ventilation pipe 11 is movably sleeved on the top surface of the trapezoidal bar 122.

[0036] When the coal filter box 13, air inlet 131, inclined plate 133, soaked clean water 134, water valve head 135 and exhaust filter screen 136 provided by the present invention are used, the air inlet 131 is used to inject the gas inside the mine ventilation pipe 11 into the coal filter box 13, and the partition 132 is used to initially block the incoming gas. As the waste gas and coal dust are continuously accumulated inside the coal filter box 13, the gas will spread toward the bottom of the inner side of the coal filter box 13. After the waste gas and coal dust pass over the inclined plate 133, the waste gas is mixed with the soaked clean water 134 inside the coal filter box 13, and the wet liquid is mixed with the coal particles inside the waste gas and coal dust. The soaked clean water 134 is used to absorb the coal dust inside the waste gas and coal dust and adsorb it inside the soaked clean water 134. After filtering the coal dust, The gas will float upward and then be discharged through the exhaust filter plate 136, while the coal dust will remain in the soaked clean water 134, so as to achieve the purpose of filtering out the coal dust inside the exhaust gas coal dust with the liquid, and avoid the coal dust inside the exhaust gas from being discharged with the gas, which will cause the coal dust inside the exhaust gas to connect with the open space outside. The granular coal dust has a large contact surface with the outside world, and the accumulated coal dust contains a lot of air. Under the external fire source, the coal dust is very likely to spontaneously combust, and the burning power of the coal dust is also increased, increasing the effect of the spontaneous combustion hazard of the coal dust. Later, the water valve head 135 is opened to replace the soaked clean water 134 inside the coal filter box 13, and the coal dust inside the soaked clean water 134 is cleaned up. The soaked clean water 134 is used to increase the wetting power of the coal dust and reduce the spontaneous combustion of the coal dust.

[0037] The working principle provided by the present invention is as follows: as the mine is continuously raised, the mine ventilation pipe 11 that needs to be connected and extended is overlapped on the top surface of the support pad 148, at which time, one end surface of the swing arm plate 147 is overlapped on the top surface of the mine ventilation pipe 11, and the hydraulic rod 145, the swing arm plate 147 and the mobile frame 14 are in a triangular support form, and at the same time, the bottom surface of one end of the convex sleeve 111 is overlapped on the surface of the push plate 1412 to limit the position of the mine ventilation pipe 11, and the mobile frame 14 is moved to the bottom surface of the rearmost mine ventilation pipe 11, so that the mobile frame 14 is perpendicular to the bottom edge position of the mine ventilation pipe 11, and the hydraulic rod 145, the swing arm plate 147 and the mobile frame 14 are in a triangular support form. The pressure rod 145 extends and lifts the semicircular support platform 146 so that the semicircular support platform 146 overlaps the bottom surface of the mine ventilation pipe 11, and observes whether the inner wall surface of the semicircular support platform 146 is completely in contact with the bottom outer surface of the mine ventilation pipe 11. If the semicircular support platform 146 is not completely in contact with the surface of the mine ventilation pipe 11, the position of the mobile frame 14 is appropriately moved and adjusted. If the semicircular support platform 146 is completely in contact with the bottom outer surface of the mine ventilation pipe 11, it can be said that the position of the mobile frame 14 is completely in contact with the bottom surface of the mine ventilation pipe 11, and then the hydraulic rod 143 is used to lift the docking limit plate 144 and the docking The top surface of the limit plate 144 is sleeved onto the inner wall surface of the limit slide groove 149, and then the slider 142 is moved to one side by the threaded rod 141. As the slider 142 continues to move, the docking limit plate 144 on the top surface of the hydraulic rod 143 will slide on the bottom surface of the swing arm plate 147, and the swing arm plate 147 is swung upward with the connection between the swing arm plate 147 and the semicircular support platform 146 as the center point, and then lifted by the hydraulic rod 143. As the swing arm plate 147 is continuously lifted, the swing arm plate 147 and the mine ventilation pipe 11 are at the same horizontal height, thereby placing the support pad The mine ventilation pipe 11 on the top surface of the platform 148 is fitted and connected with one end of the mine ventilation pipe 11 to be connected, and then the mine ventilation pipe 11 on the top surface of the support pad 148 is pushed by the pushing plate 1412 to connect the two mine ventilation pipes 11, and the ventilation pipe is swung and lifted to adjust the horizontal height of the connected pipe and the pipe to be connected, so as to avoid that the screws between the two ventilation pipes cannot be effectively connected due to a slight tilt angle of the ventilation pipe when connecting the ventilation pipes, and the bolts cannot pass through the slots of the flange on the surface of the ventilation pipe due to the tilt of the ventilation pipe, so that the ventilation pipe connection will cause gas leakage due to insufficient fit;

[0038] When the two mine ventilation pipes 11 are butted, the mine ventilation pipe 11 on the top surface of the supporting pad 148 is first attached to the surface of one end of the mine ventilation pipe 11 to be butted. When the two mine ventilation pipes 11 are attached, the pushing plate 1412 is used to push one end of the mine ventilation pipe 11. When the mine ventilation pipe 11 on the top surface of the supporting pad 148 is pushed by the pushing plate 1412, the butt groove 112 on one end of the mine ventilation pipe 11 is aligned with the other mine ventilation pipe 11. The butt joint strips 116 on the surface are butt jointed, and the butt joint strips 116 and the butt joint grooves 112 are used to seal the joint between the two mine ventilation pipes 11 to prevent gas leakage. At the same time, when the butt joint grooves 112 and the butt joint strips 116 are butt jointed, the butt joint rods 115 on the surface of one side of the convex casing 111 are sleeved into the inside of the butt joint hole 113, and the multiple butt joint rods 115 on the surface of one side of the convex casing 111 are used to support the position of the mine ventilation pipe 11 to increase the mine ventilation pipe 11 The stability of the mine ventilation pipes 11 is ensured by sealing the joint between the two mine ventilation pipes 11 to prevent the mine ventilation pipes 11 from falling slightly due to their own gravity, which may cause gaps in the joint of the mine ventilation pipes 11. The joint rod 115 is used to increase the compressive stability between the two mine ventilation pipes 11. The mine exhaust fan 118 on the inner wall of the ring 117 is rotated to blow air inside the mine ventilation pipe 11, and the mine exhaust fan 118 is used to guide the outside air into the mine ventilation pipe 11. Since each mine ventilation pipe 11 is provided with a mine exhaust fan 118, the exhaust gas can flow continuously inside the mine ventilation pipe 11, providing a driving force for a steady stream of gas. While the middle section of the mine ventilation pipe 11 is blowing air, it cooperates with the one-way ventilation pipe 114 to absorb the air in the middle section of the mine into the mine ventilation pipe 11, and cooperates with the one-way ventilation pipe 114 to make the gas flow in one direction, and as the gas continues to flow, it is infused into the interior of the coal filter box 13.
