Description

Technical Field

[0001] This invention belongs to the field of dust control technology for mine ore passes, specifically a spray dust suppression device for mine ore passes. Background Technology

[0002] A ore pass is a vertical or inclined shaft in which ore from the upper and middle sections is slid down to the lower transport roadways by its own weight. It serves as an auxiliary development roadway for transferring ore and rock in underground mines. When ore is poured into the ore pass from the unloading port, the collision with the shaft walls generates a large amount of dust. This dust disperses into the air, not only harming workers' health but also adhering to equipment, shortening its service life. Therefore, dust suppression spraying is necessary during the ore transfer process.

[0003] Patent CN202882987U discloses a dust suppression spray device for mines. Its structure uses an arc-shaped spray pipe with one end sealed and the other open. A spray head is located on the side of the spray pipe closest to the center of the arc. A hook is located in the center of the spray pipe on the opposite side of the spray head. The spray pipe is suspended from the tunnel ceiling via the hook. One open end of the spray pipe is connected to a water pipe via a rubber hose. This patent offers convenient installation and disassembly, and significantly improves dust suppression efficiency.

[0004] However, the above technical solutions still have the following shortcomings in practical applications: Multiple spray nozzles are installed at the ore unloading port to spray and suppress dust during the ore unloading process. However, because the spray range of each nozzle is fixed, and dust rapidly spreads outwards after exiting the unloading port, dust outside the spray range cannot be effectively captured, thus limiting the dust suppression effect. Furthermore, even if the number of spray nozzles is increased or the spray range is expanded, it is difficult to completely cover all dust diffusion paths, and excessive spray water will enter the ore pass along the unloading port, thereby increasing the ore moisture content, which may lead to ore powder adhesion, mud buildup on the well wall, and in severe cases, blockage of the ore pass.

[0011] Preferably, it also includes components to prevent the carrying of contaminants; The anti-pollution component includes a slider slidably disposed on one side of the adjustment plate. Sliding columns are slidably connected to both sides of the slider. A mounting base is fixedly connected to one end of the sliding column. A winding wheel is rotatably disposed on one side of the mounting base. A steel wire is wound around two adjacent winding wheels on two adjacent adjustment plates.

[0012] Preferably, a second lead screw is threadedly connected to one side of the slider, and both ends of the second lead screw are rotatably mounted on an adjustment plate.

[0015] The beneficial effects of this invention are as follows: 1. The dust suppression spray device for mine chutes described in this invention utilizes an intercepting spray assembly. When dust drifts out of the unloading port, a barrier partially seals off the unloading port area, forcibly constraining the dust's diffusion path and forcing it to exit only along the internal channels of the barrier. Multiple spray nozzles are aimed at the inside of the barrier, covering the entire cross-section of the barrier. All dust passing through the barrier must pass through the sprayed area. Thus, dust dispersion is transformed from unorganized to organized emission, significantly improving the dust suppression effect.

[0016] Meanwhile, the solution reduces water consumption while ensuring dust suppression, preventing excessive spray water from entering the ore pass through the unloading port, which would increase the ore moisture content and lead to powder ore adhesion, mud buildup on the well wall, and even blockage of the ore pass in severe cases.

[0017] 2. The dust suppression spray device for mine chutes described in this invention utilizes a pollution-preventing component. During the dust suppression process, a steel wire simultaneously scrapes off the dust adhering to the surface of the dust-blocking cloth, peeling off the dust adhering to the gaps and textures on the surface of the dust-blocking cloth. The dust then falls into the unloading port, thus avoiding the problem of dust adhering to the gaps and textures on the inner surface of the dust-blocking cloth and being difficult to spray. This prevents the dust from being shaken off by the vibration of the vehicle after the dust-blocking cloth is removed and falling into areas other than the unloading port, causing environmental pollution in the surrounding area.

Detailed Implementation

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please refer to Figures 1-8 The present invention provides a technical solution: a dust suppression spray device for mine chute, comprising a vehicle body 1, on which an intercepting spray assembly is provided; The intercepting spray assembly includes a bracket 5 fixedly connected to one side of the upper end of the vehicle body 1. A lifting plate 8 is slidably connected to one side of the bracket 5. A fixing ring 9 is fixedly connected to one end of the lifting plate 8. Multiple mounting plates 34 are evenly distributed and fixedly connected to the inner ring of the fixing ring 9 along the circumference. Multiple connecting rods 17 are rotatably arranged on the mounting plates 34. A connecting rod 18 is rotatably arranged at one end of the connecting rod 17. An adjusting plate 19 is rotatably arranged at one end of the connecting rod 18. A winding roller 23 is rotatably arranged at one end of the inner cavity of the adjusting plate 19. A dust-blocking cloth 10 is wound on the winding roller 23. The dust-blocking cloth 10 slides through one side of the adjusting plate 19, and the end of the dust-blocking cloth 10 is fixedly connected to the outer wall of the adjusting plate 19 on the other side. A water outlet pipe 21 is fixedly connected to one side of the adjusting plate 19. Multiple spray heads 25 are arranged longitudinally on the water outlet pipe 21.

[0023] In this embodiment, as Figures 2-6As shown, a water tank 2 is fixedly connected to one side of the upper end of the vehicle body 1. A water pump 3 is fixedly connected to one side of the outer wall of the water tank 2. The water inlet of the water pump 3 is connected to the inner cavity of the water tank 2. The water outlet of the water pump 3 is connected to a hose 4. One end of the hose 4 is connected to an annular pipe 11. The annular pipe 11 is fixedly sleeved on the outer ring of the fixed ring 9. Multiple hoses 12 are evenly distributed and connected along the circumference of the annular pipe 11. One end of the hose 12 is connected to one end of the water outlet pipe 21.

[0024] One end of the lifting plate 8 is threadedly connected to a lead screw 7. Both ends of the lead screw 7 are rotatably mounted on the bracket 5. One end of the bracket 5 is fixedly connected to a motor 6. The output end of the motor 6 is fixedly connected to one end of the lead screw 7.

[0025] Multiple sliding rods 13 are fixedly connected to the upper end face of the fixed ring 9. The sliding rods 13 are slidably connected to the lifting ring 14. Multiple racks 15 are evenly distributed and fixedly connected along the circumference of the inner ring of the lifting ring 14. A gear 16 is fixedly connected to one end of the connecting rod 17. The gear 16 is rotatably mounted on the mounting plate 34, and each rack 15 meshes with a gear 16. A cylinder 20 is fixedly connected to one side of the fixed ring 9. The piston end of the cylinder 20 is fixedly connected to one side of the lifting ring 14.

[0026] A spring-type spring-type 24 is sleeved on one end of the winding roller 23. One end of the spring-type spring-type 24 is fixedly connected to one side of the winding roller 23, and the other end is fixedly connected to one side of the adjusting plate 19.

[0027] Specifically, in existing technologies, multiple spray heads 25 are typically installed at the unloading port to spray and suppress dust during the unloading process. However, since the spray range of the spray heads 25 is fixed, and dust rapidly spreads in all directions after gushing out of the unloading port, dust outside the spray range cannot be effectively captured, thus limiting the dust suppression effect. Furthermore, even if the number of spray heads 25 is increased or the spray range is expanded, it is difficult to completely cover all dust diffusion paths, and excessive spray water will enter the ore pass along the unloading port, thereby increasing the ore moisture content, which may lead to ore powder adhesion, mud buildup on the well wall, and in severe cases, blockage of the ore pass.

[0028] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: First, the vehicle body 1 is moved to the unloading port. Multiple adjusting plates 19 and multiple dust-blocking cloths 10 cooperate to form a barrier structure. According to the size of the unloading port, the lifting ring 14 is moved up and down by the cylinder 20, which causes multiple racks 15 to drive multiple gears 16 to rotate simultaneously, thereby rotating multiple connecting rods 17 and 18. As a result, multiple adjusting plates 19 move radially simultaneously. When the adjusting plates 19 move, the winding roller 23 rotates under the action of the spring 24, thereby winding or unwinding the dust-blocking cloth 10, keeping the unwound portion of the dust-blocking cloth 10 taut. The size of the entire barrier can be adjusted until the edge of the barrier is aligned with the edge of the unloading port. Then, the barrier is lowered by the motor 6 driving the lead screw 7 to rotate until the bottom of the dust-blocking cloth 10 and the adjusting plates 19 are in contact with the edge of the unloading port.

[0029] At this point, the ore can be poured in through the unloading port. Simultaneously, water pump 3 is activated to draw water from water tank 2. The water flows through hose 4, ring pipe 11, hose 12, and outlet pipe 21 before being sprayed from multiple spray nozzles 25. When dust drifts out of the unloading port, the enclosure partially seals off the area, forcibly restricting the dust's diffusion path, forcing it to exit only through the internal channels of the enclosure. Multiple spray nozzles 25 are aimed at the inside of the enclosure, covering the entire cross-section of the enclosure. All dust passing through the enclosure must pass through the sprayed area. Thus, the dust is transformed from unorganized diffusion to organized emission, significantly improving dust suppression.

[0030] Meanwhile, the solution reduces water consumption while ensuring dust suppression, preventing excessive spray water from entering the ore pass through the unloading port, which would increase the ore moisture content and lead to powder ore adhesion, mud buildup on the well wall, and even blockage of the ore pass in severe cases.

[0031] In addition, when the device is not in operation, the dust-blocking cloth 10 is completely rolled up, which reduces the space occupied and avoids damage from collisions with external objects.

[0032] In this embodiment, as Figures 6-8 As shown, it also includes components to prevent the importation of contaminants; The anti-contamination component includes a slider 27 slidably disposed on one side of the adjustment plate 19. Sliding columns 29 are slidably connected to both sides of the slider 27. A mounting base 31 is fixedly connected to one end of the sliding column 29. A winding wheel 30 is rotatably disposed on one side of the mounting base 31. A steel wire 22 is wound around two adjacent winding wheels 30 on two adjacent adjustment plates 19. The steel wire 22 is in contact with the surface of the dust-blocking cloth 10.

[0033] A lead screw 26 is threadedly connected to one side of the slider 27. Both ends of the lead screw 26 are rotatably mounted on the adjusting plate 19. A motor 6 is fixedly connected to one side of the adjusting plate 19. The output end of the motor 6 is fixedly connected to one end of the lead screw 26.

[0034] The mounting base 31 is fixedly connected to the housing 33 on one side. A second spring 32 is sleeved on one end of the winding wheel 30. One side of the second spring 32 is fixedly connected to the end of the winding wheel 30, and the other end is fixedly connected to the inner wall of the housing 33.

[0035] A spring 28 is fitted onto one end of the sliding column 29. One end of the spring 28 is fixedly connected to the end of the sliding column 29, and the other end is fixedly connected to the slider 27.

[0036] Specifically, in the above solution, although the dust-blocking cloth 10 can be used to constrain the diffusion path of dust, the dust easily adheres to the gaps and textures on the inner surface of the dust-blocking cloth 10 and is difficult to spray. When the dust-blocking cloth 10 is removed from the unloading port, this dust is easily shaken off by the vibration of the vehicle body 1 and falls into the non-unloading port area, causing environmental pollution in the surrounding area.

[0037] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: When the position of the adjusting plate 19 changes, the steel wire 22 will be wound or unwound by the two winding wheels 30 due to the deformation of the second spring 32. This keeps the unwound portion of the steel wire 22 taut. Since the steel wire 22 is in close contact with the surface of the dust-blocking cloth 10 under the action of the spring 28, and the unwound portion of the steel wire 22 is the same length as the unwound portion of the dust-blocking cloth 10, during the dust suppression process, the motor 6 can drive the lead screw 26 to rotate, causing multiple sliders 27 to slide up and down simultaneously. This allows the steel wire 22 to scrape the surface of the dust-blocking cloth 10, removing dust adhering to the gaps and textures on the surface of the dust-blocking cloth 10. The dust will then fall into the unloading port, thus preventing dust from adhering to the gaps and textures on the inner surface of the dust-blocking cloth 10 and being difficult to spray. This would prevent dust from being shaken off by the vibration of the vehicle body 1 after the dust-blocking cloth 10 is removed, falling into areas outside the unloading port and causing environmental pollution.

[0038] Working principle: First, the vehicle body 1 is moved to the unloading port. Multiple adjusting plates 19 and multiple dust-blocking cloths 10 cooperate to form a barrier structure. According to the size of the unloading port, the lifting ring 14 is moved up and down by the cylinder 20, which causes multiple racks 15 to drive multiple gears 16 to rotate simultaneously, thereby rotating multiple connecting rods 17 and 18. This causes the multiple adjusting plates 19 to move radially simultaneously. Furthermore, as the adjusting plates 19 move, the winding roller 23 rotates under the action of the spring 24, thereby winding or unwinding the dust-blocking cloth 10, keeping the unwound portion of the dust-blocking cloth 10 taut. The size of the entire barrier can be adjusted until the edge of the barrier aligns with the edge of the unloading port. Then, the barrier is lowered by the motor 6 driving the lead screw 7 until the bottom of the dust-blocking cloth 10 and the adjusting plates 19 are in contact with the edge of the unloading port.

[0039] At this point, the ore can be poured in through the unloading port. Simultaneously, water pump 3 is activated to draw water from water tank 2. The water flows through hose 4, ring pipe 11, hose 12, and outlet pipe 21 before being sprayed from multiple spray nozzles 25. When dust drifts out of the unloading port, the enclosure partially seals off the area, forcibly restricting the dust's diffusion path, forcing it to exit only through the internal channels of the enclosure. Multiple spray nozzles 25 are aimed at the inside of the enclosure, covering the entire cross-section of the enclosure. All dust passing through the enclosure must pass through the sprayed area. Thus, the dust is transformed from unorganized diffusion to organized emission, significantly improving dust suppression.

[0040] Meanwhile, the solution reduces water consumption while ensuring dust suppression, preventing excessive spray water from entering the ore pass through the unloading port, which would increase the ore moisture content and lead to powder ore adhesion, mud buildup on the well wall, and even blockage of the ore pass in severe cases.

[0041] In addition, when the device is not in operation, the dust-blocking cloth 10 is completely rolled up, which reduces the space occupied and avoids damage from collisions with external objects.

[0042] When the position of the adjusting plate 19 changes, the steel wire 22 will be wound or unwound by the two winding wheels 30 due to the deformation of the second spring 32. This keeps the unwound portion of the steel wire 22 taut. Since the steel wire 22 is in close contact with the surface of the dust-blocking cloth 10 under the action of the spring 28, and the unwound portion of the steel wire 22 is the same length as the unwound portion of the dust-blocking cloth 10, during the dust suppression process, the motor 6 can drive the lead screw 26 to rotate, causing multiple sliders 27 to slide up and down simultaneously. This allows the steel wire 22 to scrape the surface of the dust-blocking cloth 10, removing dust adhering to the gaps and textures on the surface of the dust-blocking cloth 10. The dust will then fall into the unloading port, thus preventing dust from adhering to the gaps and textures on the inner surface of the dust-blocking cloth 10 and being difficult to spray. This would prevent dust from being shaken off by the vibration of the vehicle body 1 after the dust-blocking cloth 10 is removed, falling into areas outside the unloading port and causing environmental pollution.
