Description

Technical Field

[0001] This invention relates to a dust suppression device for mining, belonging to the field of mine dust removal technology. Background Technology

[0002] A mining area refers to a coalfield or a portion thereof that is planned and developed in a unified manner. It includes an area with several mine shafts or open-pit mines, and has complete production processes, surface transportation, power supply, communication dispatch, production management, and living services. Its scope often depends on the size of the ore deposit. When mining is carried out in the mine shafts, there is usually a lot of dust, so dust suppression equipment is required.

[0003] In existing technology, to achieve rotation of mining dust suppression equipment, a mining tunnel environmental protection dust removal device with announcement number CN112814722A includes a horizontal plate and wheels. Multiple wheels are fixed to the lower surface of the horizontal plate, and a rotating device is installed on the right side of the upper surface of the horizontal plate. This mining tunnel environmental protection dust removal device, through the interaction of a motor, a first gear, a second gear, a vertical rod, and a first support, allows the motor to drive the second gear to rotate via the first gear. The second gear then drives the vertical rod to rotate, which in turn drives the first vertical plate to rotate via a disc. The first vertical plate then drives a fan to rotate, thereby collecting dust from different directions. Through the interaction of a second housing, a T-shaped plate, a water pump, pipes, nozzles, and the second vertical plate, the water pump discharges water from the second housing into the pipes, which is then sprayed out through the nozzles, thus treating the dust.

[0004] In summary, the dust suppression equipment used in mining has the following technical problems: although it can treat dust during use, the working efficiency is relatively low and it consumes a lot of water, which is not conducive to environmental protection and further mining operations. There is room for improvement. Therefore, a dust suppression equipment for mining is proposed. Summary of the Invention

[0005] To address the problems of low efficiency and high water consumption in existing mining dust suppression equipment, this invention proposes a mining dust suppression device that simultaneously incorporates a dust suppression mechanism and a recovery mechanism. The dust suppression mechanism includes angle adjustment and displacement adjustment components to facilitate efficient dust absorption and processing, thereby increasing work efficiency, while also enabling water recycling.

[0006] A dust suppression device for mining includes a support plate 1, a water storage tank 2, a dust suppression mechanism, and a recovery mechanism. The water storage tank 2, the dust suppression mechanism, and the recovery mechanism are all mounted on the support plate 1. A water supply pipe is connected to the first water inlet of the water storage tank 2. The dust suppression mechanism is connected to the water outlet of the water storage tank 2. The water inlet of the recovery mechanism is connected to the water outlet of the dust suppression mechanism. The water outlet of the recovery mechanism is connected to the second water inlet of the water storage tank 2.

[0007] The dust suppression mechanism is used to suppress dust in the mine shaft, and the recycling mechanism is used to filter and recycle the wastewater generated by dust suppression, thus saving water resources.

[0008] The dust suppression mechanism includes a dust suppression device, an angle adjustment component, and a displacement adjustment component. The angle adjustment component is fixedly mounted on the support plate 1, and the displacement adjustment component is mounted on the angle adjustment component. The dust suppression device includes a first dust suppression component and a second dust suppression component. Both the first dust suppression component and the second dust suppression component are slidably mounted on the displacement adjustment component. Both the first dust suppression component and the second dust suppression component are connected to the water outlet of the water storage tank 2.

[0009] The angle adjustment component can adjust the angle of the first dust-reducing component and the second dust-reducing component, and the displacement adjustment component can adjust the distance between the first dust-reducing component and the second dust-reducing component, so as to realize the adjustment of different angles and different distances of the first dust-reducing component and the second dust-reducing component. Through the structural design of the adjustment mechanism, the device can easily absorb and treat dust in the air in a wide range of different directions, improve the dust absorption and treatment capacity, and speed up the work efficiency.

[0010] Preferably, the dust suppression device further includes a water pump 3, which is fixedly installed on the side of the water storage tank 2. The water inlet of the water pump 3 is connected to the interior of the water storage tank 2 through a water inlet pipe 4. The first dust suppression component includes a first guide frame 26 and a plurality of processing cylinders 7 fixedly installed on the first guide frame 26. The second dust suppression component includes a second guide frame and a plurality of processing cylinders 7 fixedly installed on the second guide frame. Both the first guide frame 26 and the second guide frame are slidably mounted on the displacement adjustment assembly. One end of each processing cylinder 7 is closed and the other end is fixedly provided with a perforated surface. The outer shell 9 and the top wall of the closed end of the treatment cylinder 7 are evenly provided with several drainage holes 29. The spiral tube 8 and the blower 10 are fixedly installed inside the treatment cylinder 7. The spiral tube 8 is close to the closed end of the treatment cylinder 7, and the blower 10 is close to the hollow outer shell 9 of the treatment cylinder 7. Several nozzles facing the blower 10 are evenly provided on the spiral tube 8. The spiral tubes 8 in adjacent treatment cylinders 7 are connected by a second connecting hose 6. The second connecting hose 6 is connected to the outlet of the water pump 3 through a first connecting hose 5. The drain outlet of the treatment cylinder 7 is connected to the inlet of the recycling mechanism.

[0011] The rotation of the fan 10 can generate negative pressure inside the treatment cylinder 7, drawing dust-containing air into the treatment cylinder 7. The nozzle of the spiral tube 8 sprays out uniform water mist to wash and reduce dust in the dust-containing air. The washed air is discharged through the drain hole 29.

[0012] The recycling mechanism includes a flow guide hose 11, a corrugated pipe 12, and a filter device. The filter device is fixedly installed at the top of the water storage tank 2. The drain outlet of the treatment cylinder 7 is connected to the water inlet of the flow guide hose 11. The flow guide hose 11 is connected to the water inlet at the top of the filter device through the corrugated pipe 12. The drain outlet at the bottom of the filter device is connected to the interior of the water storage tank 2.

[0013] The water containing dust in the treatment cylinder 7 is collected and transported to the filtration device through the guide hose 11 and the corrugated pipe 12 for filtration and impurity removal, and then flows back into the water storage tank 2 to realize water recycling.

[0014] Preferably, the filtration device includes a cylinder 13 and a filter plate 14 disposed inside the cylinder 13.

[0015] The angle adjustment assembly includes a first motor 15, a rotating shaft 18, and an L-shaped plate 20. The first motor 15 is fixedly mounted on the support plate 1. A semi-circular bevel gear 16 is fixedly mounted on the output shaft of the first motor 15. The bottom end of the rotating shaft 18 is rotatably mounted on the support plate 1 via a rotating bearing. The L-shaped plate 20 is fixedly mounted on the top end of the rotating shaft 18. The rotating shaft 18 is equipped with an upper bevel gear 17 and a lower bevel gear 19. The rack of the upper bevel gear 17 is set downwards, and the rack of the lower bevel gear 19 is set upwards. The upper bevel gear 17 and the lower bevel gear 19 are respectively engaged with the half-circular bevel gear 16, but the upper bevel gear 17 and the lower bevel gear 19 are not engaged with the half-circular bevel gear 16 at the same time. That is, when the upper bevel gear 17 is engaged with the rack of the half-circular bevel gear 16, the lower bevel gear 19 disengages from the rack of the half-circular bevel gear 16; when the lower bevel gear 19 is engaged with the rack of the half-circular bevel gear 16, the upper bevel gear 17 disengages from the rack of the half-circular bevel gear 16; the displacement adjustment assembly is fixedly mounted on the L-shaped plate 20.

[0016] Preferably, the gear surface of the semi-circular bevel gear 16 includes a serrated portion and a smooth portion, with the serrated portion occupying 1 / 2 of the gear surface outline.

[0017] When the rack of the semi-circular bevel gear 16 meshes with the upper bevel gear 17, the output shaft of the first motor 15 drives the semi-circular bevel gear 16 to rotate. The semi-circular bevel gear 16 drives the upper bevel gear 17 and the rotating shaft 18 to rotate. The rotating shaft 18 then drives the L-shaped plate 20 and the dust-suppressing device fixed on the L-shaped plate 20 to rotate, realizing the forward adjustment of the rotation angle. When the rack of the semi-circular bevel gear 16 rotates to disengage from the upper bevel gear 17, that is, when the rack of the semi-circular bevel gear 16 rotates to mesh with the lower bevel gear 19, the semi-circular bevel gear 16 drives the lower bevel gear 19 to rotate in the opposite direction to the rotating shaft 18. The rotating shaft 18 then drives the L-shaped plate 20 and the dust-suppressing device fixed on the L-shaped plate 20 to rotate in the opposite direction, realizing the reverse adjustment of the rotation angle. The semi-circular bevel gear 16 alternately meshes with the upper bevel gear 17 and the lower bevel gear 19, driving the dust-suppressing device to rotate back and forth, which is convenient for absorbing and treating dust in the air in different directions.

[0018] The displacement adjustment assembly includes a second motor 21, a connecting spring 27, a first connecting frame 28, and a second connecting frame. Both the first and second connecting frames are fixedly mounted on the horizontal plate of the L-shaped plate 20 via support frames. Both the first and second connecting frames are parallel to the horizontal plate of the L-shaped plate 20, and their central horizontal axes are on the same straight line. A sliding groove is provided in the middle of both the first and second connecting frames. The first dust-reducing component slides within the groove of the first connecting frame 28, and the second dust-reducing component slides within the groove of the second connecting frame. The A-end of the first dust-reducing component and the A' end of the second dust-reducing component are connected. The two ends of the connecting spring 27 are respectively connected to the A end of the first dust-suppressing component and the A' end of the second dust-suppressing component. The second motor 21 is fixed on the vertical plate of the L-shaped plate 20. The output shaft of the second motor 21 is set vertically upward. A worm gear 22 is fixedly set on the output shaft of the second motor 21. A horizontal shaft 24 is rotatably set on the vertical plate of the L-shaped plate 20 through a rotating bearing. A worm wheel 23 is fixedly set on the horizontal shaft 24. The worm wheel 23 meshes with the worm gear 22. An elliptical wheel 25 is fixedly set at the other end of the horizontal shaft 24. The outer edge of the elliptical wheel 25 is respectively attached to the A end of the first dust-suppressing component and the A' end of the second dust-suppressing component for transmission.

[0019] The output shaft of the second motor 21 drives the worm 22 to rotate, and the worm 22 drives the worm wheel 23 meshing with the worm 22 to rotate, thereby causing the elliptical wheel 25 fixed on the horizontal shaft 24 to rotate. Since the outer edge of the elliptical wheel 25 is in contact with the A end of the first dust-reducing component and the A' end of the second dust-reducing component respectively, as the outer edge of the short diameter of the elliptical wheel 25, which is in contact with the A end of the first dust-reducing component and the A' end of the second dust-reducing component, gradually changes to the outer edge of the long diameter, it pushes the first dust-reducing component to slide away from the A' end of the second dust-reducing component in the groove of the first connecting frame 28, and at the same time pushes the second dust-reducing component to slide away from the A' end of the first dust-reducing component in the groove of the second connecting frame. The sliding of the ends increases the distance between the first and second dust-reducing components, while the connecting spring 27 is stretched to generate elastic force. When the outer edge of the major diameter of the elliptical wheel 25, which is in contact with the A end of the first dust-reducing component and the A' end of the second dust-reducing component, gradually changes to the outer edge of the minor diameter, the connecting spring 27 contracts and recovers, pulling the first dust-reducing component to slide in the groove of the first connecting frame 28 towards the A' end of the second dust-reducing component. At the same time, it pulls the second dust-reducing component to slide in the groove of the second connecting frame towards the A end of the first dust-reducing component, thus increasing the distance between the first and second dust-reducing components. Simultaneously, the deformation of the connecting spring 27 decreases, and the elastic force weakens.

[0020] The bottom end of the support plate 1 is fixedly provided with a support leg, and the bottom of the support leg is provided with a walking wheel.

[0021] A handle is fixedly provided on the side of the support plate 1.

[0022] The beneficial effects of this invention are:

[0023] (1) The present invention is equipped with both a dust collection mechanism and a recycling mechanism, which facilitates efficient dust absorption and treatment, speeds up work efficiency, and simultaneously enables the recycling of water.

[0024] (2) The present invention provides an angle adjustment component and a displacement adjustment component in the dust removal mechanism, which can realize the absorption and treatment of air dust in a wide range of different directions. Attached Figure Description

Detailed Implementation

[0032] The present invention will be further described in detail below with reference to specific embodiments, but the scope of protection of the present invention is not limited to the content described.

[0033] Example 1: A dust suppression device for mining (see...) Figure 1-2 The system includes a support plate 1, a water storage tank 2, a dust suppression mechanism, and a recycling mechanism. The water storage tank 2, the dust suppression mechanism, and the recycling mechanism are all mounted on the support plate 1. The first inlet of the water storage tank 2 is connected to a water supply pipe. The dust suppression mechanism is connected to the outlet of the water storage tank 2. The inlet of the recycling mechanism is connected to the outlet of the dust suppression mechanism. The outlet of the recycling mechanism is connected to the second inlet of the water storage tank 2. The dust suppression mechanism is used to suppress dust in the mine shaft, and the recycling mechanism is used to filter and recycle the wastewater generated by dust suppression, thus saving water resources.

[0034] The dust suppression mechanism includes a dust suppression device, an angle adjustment component, and a displacement adjustment component. The angle adjustment component is fixedly mounted on the support plate 1, and the displacement adjustment component is mounted on the angle adjustment component. The dust suppression device includes a first dust suppression component and a second dust suppression component. Both the first and second dust suppression components are slidably mounted on the displacement adjustment component. Both the first and second dust suppression components are connected to the water outlet of the water storage tank 2. The angle adjustment component can adjust the angle of the first and second dust suppression components, and the displacement adjustment component can adjust the distance between the first and second dust suppression components, thereby achieving adjustments to different angles and distances of the first and second dust suppression components. Through the structural design of the adjustment mechanism, this device can easily absorb and treat dust from the air in different directional areas.

[0035] The specific steps for using dust suppression equipment in mining are as follows:

[0036] S1. The water in the water storage tank 2 is subjected to dust suppression through the first dust suppression component and the second dust suppression component of the dust suppression mechanism. During the dust suppression process, the angle adjustment component and the distance adjustment component are used to adjust the angle of the first dust suppression component and the second dust suppression component, thereby achieving dust suppression in a wide range of different areas.

[0037] S2. Water containing dust is collected, purified by a recycling mechanism, and returned to the water storage tank, thus realizing the recycling of water resources.

[0038] Example 2: The dust suppression equipment for mining in this example has a basically the same structure as the dust suppression equipment for mining in Example 1, except that: Figure 3 As shown, the dust suppression device also includes a water pump 3, which is fixedly installed on the side of the water storage tank 2. The water inlet of the water pump 3 is connected to the interior of the water storage tank 2 through a water inlet pipe 4. The first dust suppression component includes a first guide frame 26 and several processing cylinders 7 fixedly installed on the first guide frame 26. The second dust suppression component includes a second guide frame and several processing cylinders 7 fixedly installed on the second guide frame. Both the first guide frame 26 and the second guide frame are slidably mounted on the displacement adjustment assembly. One end of the processing cylinder 7 is closed and the other end is fixedly provided with a perforated outer shell. The shell 9 and the top wall of the closed end of the treatment cylinder 7 are evenly provided with several drainage holes 29. The spiral tube 8 and the blower 10 are fixedly installed inside the treatment cylinder 7. The spiral tube 8 is close to the closed end of the treatment cylinder 7, and the blower 10 is close to the hollow shell 9 of the treatment cylinder 7. Several nozzles facing the blower 10 are evenly provided on the spiral tube 8. The spiral tubes 8 in adjacent treatment cylinders 7 are connected by a second connecting hose 6. The second connecting hose 6 is connected to the outlet of the water pump 3 through a first connecting hose 5. The drain outlet of the treatment cylinder 7 is connected to the inlet of the recycling mechanism.

[0039] The rotation of the fan 10 can generate negative pressure inside the treatment cylinder 7, drawing dust-laden air from the hollow outer shell 9 into the treatment cylinder 7. The water in the water tank 2 is pressurized by the water pump 3 and transported through the first connecting hose 5 and the second connecting hose 6 to the spiral tube 8 inside each treatment cylinder 7. The nozzle of the spiral tube 8 sprays the pressurized water into a uniform water mist to wash and reduce dust in the air.

[0040] The rotation of the fan 10 creates negative air pressure inside the treatment cylinder 7, allowing the external dust airflow to enter the treatment cylinder 7 through the air holes inside the hollow shell 9. The dust is then uniformly misted by the nozzles of the spiral tube 8 in the treatment cylinder 7, and the dust-suppressed airflow is discharged along the inner wall of the treatment cylinder 7 through the drain hole 29, thus achieving continuous dust suppression.

[0041] Example 3: The dust suppression equipment for mining in this example has a basically the same structure as the dust suppression equipment for mining in Example 2, except that: Figure 3As shown, the recycling mechanism includes a flow guide hose 11, a corrugated pipe 12, and a filter device. The filter device is fixedly installed at the top of the water storage tank 2. The drain outlet of the treatment cylinder 7 is connected to the water inlet of the flow guide hose 11. The flow guide hose 11 is connected to the water inlet at the top of the filter device through the corrugated pipe 12. The drain outlet at the bottom of the filter device is connected to the interior of the water storage tank 2. The filter device includes a cylinder 13 and a filter plate 14 installed inside the cylinder 13.

[0042] The water containing dust in the treatment cylinder 7 is collected and transported to the cylinder 13 of the filter device through the guide hose 11 and the corrugated pipe 12. It is then filtered and impurities are removed by the filter plate 14, and then it flows back into the water storage tank 2 to realize the recycling of water.

[0043] The bottom end of the cylinder 13 can be fixed to the top of the water storage tank 2 by bolts to facilitate the disassembly and separation of the cylinder 13. The bottom of the cylinder 13 can be connected to the second water inlet at the top of the water storage tank 2 through a drain pipe. The filter plate 14 is fixed to the inner side of the fixed cylinder 13 by a snap-fit, which facilitates the cleaning or replacement of the filter plate 14 in the future. With the filter plate 14, wastewater can be filtered, recycled and reused, which is beneficial to environmental protection.

[0044] Example 4: The dust suppression equipment for mining in this example has a basically the same structure as the dust suppression equipment for mining in Example 3, the difference being: Figure 4 As shown, the angle adjustment assembly includes a first motor 15, a rotating shaft 18, and an L-shaped plate 20. The first motor 15 is fixedly mounted on the support plate 1. A semi-circular bevel gear 16 is fixedly mounted on the output shaft of the first motor 15. The bottom end of the rotating shaft 18 is rotatably mounted on the support plate 1 via a rotating bearing. The L-shaped plate 20 is fixedly mounted on the top end of the rotating shaft 18. The rotating shaft 18 is equipped with an upper bevel gear 17 and a lower bevel gear 19. The rack of the upper bevel gear 17 is set downwards, and the rack of the lower bevel gear 19 is set upwards. The upper bevel gear 17 and the lower bevel gear 19 are respectively engaged with the half-circular bevel gear 16, but not simultaneously engaged with the half-circular bevel gear 16. That is, when the upper bevel gear 17 is engaged with the rack of the half-circular bevel gear 16, the lower bevel gear 19 disengages from the rack of the half-circular bevel gear 16; when the lower bevel gear 19 is engaged with the rack of the half-circular bevel gear 16, the upper bevel gear 17 disengages from the rack of the half-circular bevel gear 16. The displacement adjustment assembly is fixedly mounted on the L-shaped plate 20. The gear surface of the half-circular bevel gear 16 includes a serrated portion and a smooth portion, with the serrated portion occupying 1 / 2 of the gear surface outline.

[0045] When the rack of the half-circular bevel gear 16 meshes with the upper bevel gear 17, the output shaft of the first motor 15 drives the half-circular bevel gear 16 to rotate. The half-circular bevel gear 16 drives the upper bevel gear 17 and the rotating shaft 18 to rotate. The rotating shaft 18 then drives the L-shaped plate 20 and the dust-suppressing device fixed on the L-shaped plate 20 to rotate, realizing the forward adjustment of the rotation angle. When the rack of the half-circular bevel gear 16 rotates to disengage from the upper bevel gear 17, that is, when the rack of the half-circular bevel gear 16 rotates to mesh with the lower bevel gear 19, the half-circular bevel gear 16 drives the lower bevel gear 19 to rotate in the opposite direction to the rotating shaft 18. The rotating shaft 18 then drives the L-shaped plate 20 and the dust-suppressing device fixed on the L-shaped plate 20 to rotate in the opposite direction, realizing the reverse adjustment of the rotation angle. The half-circular bevel gear 16 alternately meshes with the upper bevel gear 17 and the lower bevel gear 19, driving the dust-suppressing device to rotate back and forth, which is convenient for absorbing and treating dust in the air in a wide range of different directions.

[0046] like Figure 5-6 As shown, the displacement adjustment assembly includes a second motor 21, a connecting spring 27, a first connecting frame 28, and a second connecting frame. Both the first connecting frame 28 and the second connecting frame are fixedly mounted on the horizontal plate of the L-shaped plate 20 via support frames. Both the first connecting frame 28 and the second connecting frame are parallel to the horizontal plate of the L-shaped plate 20, and their central horizontal axes are on the same straight line. A sliding groove is provided in the middle of both the first connecting frame 28 and the second connecting frame. The first dust-reducing component slides within the sliding groove of the first connecting frame 28, and the second dust-reducing component slides within the sliding groove of the second connecting frame. The A-end of the first dust-reducing component and the A' end of the second dust-reducing component are connected. The heads are arranged opposite each other. The two ends of the connecting spring 27 are respectively connected to the A end of the first dust-reducing component and the A' end of the second dust-reducing component. The second motor 21 is fixed on the vertical plate of the L-shaped plate 20. The output shaft of the second motor 21 is set vertically upward. A worm gear 22 is fixedly set on the output shaft of the second motor 21. A horizontal shaft 24 is rotatably set on the vertical plate of the L-shaped plate 20 through a rotating bearing. A worm wheel 23 is fixedly set on the horizontal shaft 24. The worm wheel 23 meshes with the worm gear 22. An elliptical wheel 25 is fixedly set on the other end of the horizontal shaft 24. The outer edge of the elliptical wheel 25 is respectively attached to the A end of the first dust-reducing component and the A' end of the second dust-reducing component for transmission.

[0047] The output shaft of the second motor 21 drives the worm 22 to rotate, and the worm 22 drives the worm wheel 23 meshing with the worm 22 to rotate, thereby causing the elliptical wheel 25 fixed on the horizontal shaft 24 to rotate. Since the outer edge of the elliptical wheel 25 is in contact with the A end of the first dust-reducing component and the A' end of the second dust-reducing component respectively, as the minor diameter outer edge of the elliptical wheel 25, which is in contact with the A end of the first dust-reducing component and the A' end of the second dust-reducing component, gradually changes to the major diameter outer edge, it pushes the first dust-reducing component to slide away from the A' end of the second dust-reducing component in the groove of the first connecting frame 28, and at the same time pushes the second dust-reducing component away from the A end of the first dust-reducing component in the groove of the second connecting frame. The sliding of the head increases the distance between the first and second dust-reducing components, while the connecting spring 27 is stretched to generate elastic force. When the outer edge of the major diameter of the elliptical wheel 25, which is in contact with the A end of the first dust-reducing component and the A' end of the second dust-reducing component, gradually changes to the outer edge of the minor diameter, the connecting spring 27 contracts and recovers, pulling the first dust-reducing component to slide in the groove of the first connecting frame 28 towards the A' end of the second dust-reducing component. At the same time, it pulls the second dust-reducing component to slide in the groove of the second connecting frame towards the A end of the first dust-reducing component, thus increasing the distance between the first and second dust-reducing components. Simultaneously, the deformation of the connecting spring 27 decreases, and the elastic force weakens.

[0048] Example 5: The dust suppression equipment for mining in this example has a basically the same structure as the dust suppression equipment for mining in Example 4, the difference being: Figure 1 As shown, a support leg is fixedly installed at the bottom of the support plate 1, and a traveling wheel is installed at the bottom of the support leg. A handle is fixedly installed on the side of the support plate 1. The dust suppression equipment for mining can be moved in the mine through the handle and the traveling wheel.

[0049] The specific embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
