Description

Technical Field

[0001] This invention relates to the field of ore hoisting and transportation technology in underground metal and non-metal mines, specifically to a skip shaft cleaning system. Background Technology

[0002] When hoisting ore using a skip shaft, fine ore will spill to the bottom of the shaft, and seepage water from the skip shaft will also fall to the bottom. Both the fine ore and the accumulated water need to be recovered. Current technologies often use elevator shafts, tipping mine cars, and manual carts to clean and recover the fine ore at the bottom of the shaft. However, this method is complex to operate, has low production efficiency, requires many operators, and is labor-intensive. Alternatively, a fine ore bin can be used to collect the fine ore, and continuous transport equipment can be used to clean and recover the fine ore within the bin. However, as the fine ore and accumulated water accumulate, the water level in the bin also rises. The higher the water level, the greater the pressure on the bin, potentially leading to a collapse. Furthermore, blockages can easily occur at the bin outlet, and the transport equipment experiences high pressure and high energy consumption. A common method is to install a water storage tank at the bottom of the shaft to collect the accumulated water and use submersible pumps to clean and recover it. However, this method requires regular manual cleaning of the sludge at the bottom of the tank, resulting in low production efficiency, high labor intensity, and a large number of operators. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention propose a skip shaft cleaning system that not only facilitates unmanned recovery of ore powder and accumulated water, but also eliminates the safety hazard of ore powder bins being easily crushed and prevents ore powder from clogging the outlet.

[0004] The skip shaft cleaning system of this invention includes:

[0005] A powder ore bin, the powder ore bin having a communicating chamber and an outlet, the chamber containing powder ore and water, and the outlet being suitable for discharging material;

[0006] A collection device is provided on the powder ore bin and communicates with the chamber so that the water accumulated in the chamber can flow into the collection device;

[0007] A transport device, at least a portion of which is located at the outlet, wherein fine ore in the chamber is discharged through the outlet and falls onto the transport device for transporting the fine ore by the transport device;

[0008] An anti-clogging device is provided at the outlet, and the anti-clogging device is used to agitate the ore powder at the outlet so that the ore powder is less likely to clog at the outlet.

[0009] In the skip shaft cleaning system of this invention, the fine ore in the chamber falls onto the transport device through the outlet, and is then transported by the transport device to clean and recycle the fine ore in the ore bin. As more and more fine ore accumulates in the chamber, the water level in the ore bin also increases, causing the water level in the chamber to rise continuously. When the water level rises to the collection device, the additional water in the chamber can flow into the collection device, reducing the water accumulation in the chamber and thus reducing the pressure of the water on the fine ore bin. In addition, the anti-blocking device makes it easier for the fine ore in the chamber to fall onto the transport device, thereby reducing the pressure on the fine ore bin when the fine ore accumulates and blocks in the chamber, ensuring the structural stability of the fine ore bin, effectively eliminating the safety hazard of the skip shaft cleaning system of this invention being easily crushed, and also effectively reducing the pressure of fine ore on the transport device and reducing the energy consumption of the transport device.

[0038] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0039] like Figure 1-5 As shown, the skip shaft cleaning system of this invention includes a fine ore bin 100, a collection device 3, a transport device 4, and an anti-clogging device 5. The fine ore bin 100 has a communicating chamber and an outlet 23. The chamber contains fine ore and water, and the outlet 23 is suitable for discharging material.

[0040] like Figure 1 and Figure 3 As shown, the collection device 3 is installed on the ore powder bin 100 and communicates with the chamber so that the water accumulated in the chamber can flow into the collection device 3. At least part of the transport device 4 is located at the outlet 23. The ore powder in the chamber is discharged through the outlet 23 and falls onto the transport device 4 for transporting the ore powder.

[0041] An anti-clogging device 5 is installed at outlet 23. This device agitates the powder at outlet 23 to prevent blockage. Specifically, the agitation ensures the powder in the chamber is stably discharged from outlet 23 and falls onto the conveyor device 4, reducing the occurrence of production accidents. Furthermore, it reduces the pressure of the powder on the conveyor device 4. The stable falling of the powder onto the conveyor device 4 also enhances its receiving capacity, improving its efficiency and reducing energy consumption.

[0042] In the skip shaft cleaning system of this embodiment, the powdered ore in the chamber falls onto the transport device 4 through the outlet 23, and is transported by the transport device 4 to clean and recycle the powdered ore in the powdered ore bin 100. As more and more powdered ore accumulates in the chamber, the water level in the powdered ore bin 100 also increases, causing the water level in the chamber to rise continuously. When the water level rises to the collection device 3, the additional water in the chamber can flow into the collection device 3, reducing the water level in the chamber and thus reducing the pressure of the water on the powdered ore bin 100. In addition, the anti-blocking device 5 makes it easier for the powdered ore in the chamber to fall onto the transport device 4, thereby reducing the pressure on the powdered ore bin 100 when the powdered ore accumulates and blocks in the chamber, ensuring the structural stability of the powdered ore bin 100, effectively eliminating the safety hazard of the skip shaft cleaning system of this embodiment being easily crushed, and also effectively reducing the powdered ore pressure on the transport device 4 and reducing the energy consumption of the transport device 4.

[0043] Specifically, the ore powder bin 100 includes a first bin body 1 and a second bin body 2 arranged sequentially in a vertical direction. The first bin body 1 has a first chamber 11, an inlet 12 and a first opening 13. The inlet 12 and the first opening 13 are connected to the first chamber 11. The first chamber 11 is suitable for containing ore powder. The inlet 12 is formed at the upper end of the first bin body 1, and the first opening 13 is formed at the lower end of the first bin body 1. The inlet 12 is suitable for feeding material, and the first opening 13 is suitable for discharging material.

[0044] Specifically, such as Figure 1 and Figure 3 As shown, the first compartment 1 includes a first beam segment 14, a first connector 15, and a first wall panel 16. The first wall panel 16 is arranged around a perimeter so that the inner circumferential surface of the first wall panel 16 forms a first chamber 11, and the cross-sectional area of ​​the upper end of the first chamber 11 is greater than the cross-sectional area of ​​the lower end of the first chamber 11.

[0045] There are multiple first beam segments 14, which are divided into multiple groups. Each group of first beam segments 14 includes multiple first beam segments 14. The multiple groups of first beam segments 14 are arranged at intervals in the vertical direction. The multiple first beam segments 14 in each group are arranged around the outer periphery of the first wall panel 16 and are connected end to end to enhance the structural strength and rigidity of the first wall panel 16.

[0046] There are multiple first connectors 15, which are divided into multiple groups, each group including multiple first connectors 15. The multiple groups of first connectors 15 are arranged at intervals in the vertical direction, and the multiple groups of first connectors 15 and multiple groups of first beam segments 14 are arranged alternately. The multiple first connectors 15 in each group are arranged in a circle at intervals. One group of first connectors 15 connects two adjacent groups of first beam segments 14, and at least a portion of the first connector 15 is connected to the outer wall surface of the first wall panel 16 to further enhance the structural strength and rigidity of the first wall panel 16.

[0047] Specifically, the second silo 2 has a second chamber 21 and a second opening 22. The first chamber 11 and the second chamber 21 form a chamber. The second opening 22 is formed at the upper end of the second silo 2 and communicates with the first opening 13 and the second chamber 21, and the outlet 23 is formed at the lower end of the second silo 2 and communicates with the second chamber 21. The second chamber 21 is suitable for containing fine ore. The cross-sectional area of ​​the lower end of the first silo 1 is smaller than the cross-sectional area of ​​the upper end of the second silo 2, at least a portion of the lower end of the first silo 1 is located within the second chamber 21, and the collecting device 3 is located between the first silo 1 and the second silo 2.

[0048] Specifically, such as Figure 1 and Figure 3As shown, the second compartment 2 includes a second beam segment 24, a second connector 25, and a second wall panel 26. The second wall panel 26 is arranged around a perimeter so that the inner circumferential surface of the second wall panel 26 forms a second chamber 21. The cross-sectional area of ​​the upper end of the second chamber 21 is larger than the cross-sectional area of ​​the lower end of the second chamber 21, and the cross-sectional area of ​​the upper end of the second chamber 21 is larger than the cross-sectional area of ​​the lower end of the first chamber 11.

[0049] There are multiple second beam segments 24, which are divided into multiple groups. Each group of second beam segments 24 includes multiple second beam segments 24. The multiple groups of second beam segments 24 are arranged at intervals in the vertical direction. The multiple second beam segments 24 in each group are arranged around the outer periphery of the second wall panel 26 and are connected end to end to enhance the structural strength and rigidity of the second wall panel 26.

[0050] There are multiple second connectors 25, which are divided into multiple groups, each group including multiple second connectors 25. The multiple groups of second connectors 25 are arranged at intervals in the vertical direction, and the multiple groups of second connectors 25 and multiple groups of second beam segments 24 are arranged alternately. The multiple second connectors 25 in each group are arranged in a circle at intervals. One group of second connectors 25 connects two adjacent groups of second beam segments 24, and at least a portion of the second connector 25 is connected to the outer wall surface of the second wall panel 26 to further enhance the structural strength and rigidity of the second wall panel 26.

[0051] In some embodiments, such as Figure 1 and Figure 3 As shown, the skip shaft is located above the first chamber 1. When the skip shaft lifts ore, a small portion of the ore spills into the first chamber 11 through inlet 12. Simultaneously, seepage water from the skip shaft also falls into the first chamber 11, filling the gaps in the fine ore. The fine ore and water accumulate in the second chamber 21 after passing through the first chamber 11. When the fine ore reaches the position of the collection device 3 located between the first chamber 1 and the second chamber 2, the second chamber 2 is filled with fine ore. Further spillage of fine ore will fill the first chamber 1. If the fine ore contains excessive mud and sand, the water level in the second chamber 21 will increase, rising until it reaches the position of the collection device 3. After that, the seepage water will flow into the collection device 3, preventing the water level in the second chamber 21 from rising further.

[0052] In some embodiments, the collecting device 3 has a third chamber 31, which is formed between the outer peripheral surface of the lower end of the first chamber 1 and the inner peripheral surface of the upper end of the second chamber 2. The third chamber 31 communicates with the first chamber 11 and the second chamber 21 so that the water accumulated in the first chamber 11 and the second chamber 21 can flow into the third chamber 31.

[0053] Specifically, the cross-sectional area of ​​the lower end of the first chamber 1 is smaller than the cross-sectional area of ​​the upper end of the second chamber 2, allowing the lower end of the first chamber 1 to extend downward into the second chamber 21. This creates a reserved space between the outer circumferential surface of the lower end of the first chamber 1 and the inner circumferential surface of the upper end of the second chamber 2, within which the third chamber 31 is formed. When the water level in the second chamber 21 rises to the reserved space, the water flows into the third chamber 31, preventing the water level in the second chamber 21 from rising further. This reduces the water pressure in the second chamber 21 and effectively eliminates the safety hazard of the second chamber 2 collapsing.

[0054] In some embodiments, such as Figure 3 As shown, the collection device 3 also includes an overflow component 32, which is connected to the third chamber 31 so that the water in the third chamber 31 can flow into the overflow component 32.

[0055] Specifically, the overflow component 32 is arranged around the outer periphery of the upper end of the second chamber 2, and the overflow component 32 is located at the upper end of the third chamber 31. The overflow component 32 is connected to the third chamber 31 so that the water in the third chamber 31 can flow into the overflow component 32. This not only releases the volume of the third chamber 31 so that the third chamber 31 can hold more water, but also prevents the water in the overflow component 32 from flowing back into the third chamber 31.

[0056] In some embodiments, such as Figure 3 As shown, the collection device 3 also includes a connecting member 33, which connects the third chamber 31 and the overflow member 32. Water in the third chamber 31 can flow into the overflow member 32 through the connecting member 33.

[0057] Specifically, there are multiple connecting members 33, which are arranged at intervals around the outer periphery of the upper end of the second chamber 2. The connecting members 33 connect the third chamber 31 and the overflow member 32, so that the water in the third chamber 31 can flow into the overflow member 32 through the connecting members 33, and can also effectively prevent the water in the overflow member 32 from flowing back into the third chamber 31.

[0058] In some embodiments, such as Figure 1 and Figure 4 As shown, the anti-blocking device 5 includes a housing 51, a mounting shaft 52, an anti-blocking component 53, and a driving component 54. The housing 51 has a fourth chamber 511, a third opening 512, and a fourth opening 513. The third opening 512 and the fourth opening 513 are connected to the fourth chamber 511. The fine ore discharged from the outlet 23 falls into the fourth chamber 511 through the third opening 512, and the fourth opening 513 is used to discharge the fine ore onto the conveying device 4.

[0059] At least a portion of the mounting shaft 52 is disposed within the fourth chamber 511, and the mounting shaft 52 is along a first direction (e.g., Figure 4Extending in the left-right direction (as shown), the mounting shaft 52 can rotate relative to the housing 51 about a first direction. The anti-blocking component 53 is located in the fourth chamber 511 and is mounted on the mounting shaft 52. The driving component 54 is connected to the mounting shaft 52 and is used to drive the mounting shaft 52 to rotate about the first direction to drive the anti-blocking component 53 to rotate, thereby agitating the powder ore in the fourth chamber 511 and at the outlet 23.

[0060] Specifically, such as Figure 4 As shown, the mounting shaft 52 extends in the left-right direction, with both ends of the mounting shaft 52 extending out of the fourth chamber 511. Multiple anti-blocking elements 53 are present, divided into three groups, each group including at least one anti-blocking element 53. The three groups of anti-blocking elements 53 are evenly spaced around the outer circumferential surface of the mounting shaft 52. At least one anti-blocking element 53 in each group is spaced apart on the outer circumferential surface of the mounting shaft 52 in the left-right direction, and at least one anti-blocking element 53 in adjacent groups is staggered. One end of the anti-blocking element 53 is connected to the outer circumferential surface of the mounting shaft 52, and the other end of the anti-blocking element 53 extends away from the mounting shaft 52.

[0061] The driving component 54 is connected to one end of the mounting shaft 52 to drive the mounting shaft 52 to rotate around the first direction, thereby driving the three sets of anti-blocking components 53 to rotate around the first direction. This improves the stirring efficiency of the anti-blocking components 53 on the powder in the fourth chamber 511, effectively solves the problem of powder blockage in the fourth chamber 511 and at the outlet 23, and reduces the occurrence of safety accidents.

[0062] In some embodiments, such as Figure 4 As shown, there are two mounting shafts 52, and the two mounting shafts 52 are along the second direction (e.g., Figure 4 (As shown) The components are arranged at intervals, with the second direction orthogonal to the vertical direction and the first direction. The three sets of anti-blocking components 53 on the two adjacent mounting shafts 52 are staggered, which further improves the stirring efficiency of the anti-blocking components 53 on the powder in the fourth chamber 511.

[0063] In some embodiments, such as Figure 4 As shown, the anti-blocking device 5 also includes a support frame 55 and a mounting base 56. The support frame 55 is used to support the housing 51 and the drive component 54. Specifically, the housing 51 is mounted on the support frame 55, the drive component 54 is also mounted on the support frame 55, the top of the support frame 55 supports the housing 51 and the drive component 54, and the base of the support frame 55 is supported on a concrete foundation.

[0064] There are four mounting bases 56, divided into two groups of two, with each group consisting of two mounting bases 56 arranged opposite each other. The two groups of mounting bases 56 are spaced apart in a second direction. Two mounting shafts 52 are correspondingly arranged one-to-one with each group of mounting bases 56. One mounting shaft 52 is mounted on one group of mounting bases 56, with one end of the shaft 52 connected to one of the mounting bases 56 in that group, and the other end connected to the other mounting base in that group. The other mounting shaft 52 is mounted on the other group of mounting bases 56, with one end connected to one of the mounting bases 56 in that group, and the other end connected to the other mounting base in that group.

[0065] In some embodiments, such as Figure 3 and Figure 5 As shown, the skip shaft cleaning system also includes a water collection device 6, which has a fifth chamber 61. The fifth chamber 61 is connected to the overflow component 32 so that the water accumulated in the third chamber 31 can flow into the fifth chamber 61.

[0066] Specifically, the overflow component 32 is connected to the fifth chamber 61 so that the water in the overflow component 32 can flow into the fifth chamber 61, thereby releasing the volume of the fifth chamber 61 so that the third chamber 31 can hold more water.

[0067] In some embodiments, such as Figure 5 As shown, the water collection device 6 also includes a first branch pipe 62, a second branch pipe 63, a submersible pump 64, and an electrical device 65. The first branch pipe 62 connects the fifth chamber 61 and the overflow component 32, allowing water in the third chamber 31 to flow into the fifth chamber 61 through the first branch pipe 62. The second branch pipe 63 connects the fifth chamber 61 to the outside, allowing water in the fifth chamber 61 to be discharged through the second branch pipe 63. The submersible pump 64 is connected to the second branch pipe 63 and is used to pump water from the fifth chamber 61 into the second branch pipe 63 and then discharge it. The electrical device 65 is electrically connected to the submersible pump 64 and is used to supply power to and control the submersible pump 64.

[0068] Specifically, the water in the third chamber 31 flows into the fifth chamber 61 through the first branch pipe 62. The electrical equipment 65 supplies power to the submersible pump 64 so that the submersible pump 64 pumps the water in the fifth chamber 61 into the second branch pipe 63 and discharges it, thereby reducing the water in the fifth chamber 61. Thus, the water collection device 6 is simple to operate, saves manpower, and is highly efficient when draining water.

[0069] In some embodiments, there are two first branch pipes 62, which are connected to the overflow member 32 at intervals, so that the water in the third chamber 31 can flow into the fifth chamber 61 at the same time through the two first branch pipes 62, thereby improving the efficiency of water drainage in the third chamber 31.

[0070] In some embodiments, such as Figure 5 As shown, the water collection device 6 also includes a stirring element 66 and a valve assembly 67. At least a portion of the stirring element 66 is disposed within the fifth chamber 61, and the stirring element 66 is used to stir the accumulated water in the fifth chamber 61 to mix the sediment at the bottom of the fifth chamber 61 into the accumulated water. Specifically, the bottom of the water collection device 6 is provided with an opening 68, and at least a portion of the stirring element 66 passes through the opening 68 and is located inside the fifth chamber 61.

[0071] In some embodiments, such as Figure 2 As shown, the water collection device 6 also includes a water-sealed pool 10, the top of which is connected to the top of the fifth chamber 61, and the clear water in the fifth chamber 61 flows into the water-sealed pool 10. The water-sealed pool 10 has a water seal (not shown), which is disposed between the outer peripheral surface of the stirring member 66 and the inner peripheral surface of the opening 68, and the water seal is arranged around the outer peripheral surface of the stirring member 66 to seal the gap between the stirring member 66 and the opening 68.

[0072] Valve assembly 67 is disposed on the second branch pipe 63, and is used to open or close the second branch pipe 63. Specifically, valve assembly 67 includes an electric gate valve 671 and a check valve 672, with the electric gate valve 671 located above the check valve 672. The electric gate valve 671 is used to control the opening and closing of the second branch pipe 63, and the check valve 672 is used to prevent water in the second branch pipe 63 from flowing back into the fifth chamber 61.

[0073] In some embodiments, the water in the powder silo 100 is sewage. The sewage collected by the collection device 3 flows into the fifth chamber 61. The sewage gradually settles and clarifies in the fifth chamber 61, and the silt in the sewage will sink to the bottom of the fifth chamber 61.

[0074] In some embodiments, such as Figure 5 As shown, the water collection device 6 also includes a water level gauge 69, which is located inside the fifth chamber 61 and extends vertically. When the water level in the fifth chamber 61 rises to the highest level of the water level gauge 69, the electrical equipment 65 automatically starts the submersible pump 64 to discharge the water in the fifth chamber 61 through the second branch pipe 63 into the mine drainage system, thereby reducing the water level in the fifth chamber 61. When the water level in the fifth chamber 61 drops to the lowest level of the water level gauge 69, the electrical equipment 65 automatically stops the submersible pump 64 to allow the fifth chamber 61 to begin storing water.

[0075] When the water collection device 6 cleans the sludge, the agitator 66 is first started to stir up the sludge at the bottom of the fifth chamber 61 and mix it with the accumulated water. Then the submersible pump 64 is turned on to discharge the sludge along with the accumulated water through the second branch pipe 63 and into the mine drainage system. This realizes the automatic cleaning and recycling of wastewater in the skip shaft. As a result, the water collection device 6 can realize automatic drainage and periodic automatic sludge cleaning, with high production efficiency and no operators.

[0076] In some embodiments, such as Figure 2 As shown, there are two agitators 66, which are arranged at intervals along the front-back direction to improve the agitation efficiency of the agitators 66 on the water accumulated in the fifth chamber 61. The front-back direction is orthogonal to the up-down direction.

[0077] In some embodiments, such as Figure 1 and Figure 2 As shown, the transport device 4 includes a first transport member 41 and a second transport member 42. One end of the first transport member 41 is located at the outlet 23, and the other end of the first transport member 41 extends upward and is inclined away from the powder ore bin 100. The powder ore in the second chamber 21 is discharged through the outlet 23 and falls onto one end of the first transport member 41, which transports the powder ore to the other end of the first transport member 41. Specifically, one end of the first transport member 41 is located below the fourth opening 513 to facilitate receiving the powder ore, and the other end of the first transport member 41 extends upward and away from the first bin body 1.

[0078] One end of the second transport member 42 overlaps with the other end of the first transport member 41. The other end of the second transport member 42 extends upward and slopes towards the adjacent fines bin 100. The second transport member 42 is used to receive the fines transported from the first transport member 41 and transport the fines to an external system. Specifically, one end of the second transport member 42 is located below the other end of the first transport member 41, and the other end of the second transport member 42 extends upward and towards the first bin 1. After the first transport member 41 transports the fines to its other end, the fines are transferred from the first transport member 41 to one end of the second transport member 42, and then the second transport member 42 transports the fines to its other end. Finally, the fines are transferred from the second transport member 42 to the skip loading system.

[0079] In some embodiments, the chamber of the ore powder bin 100 is equipped with a level gauge (not shown) to detect the amount of ore powder in the chamber. When the chamber is full of ore powder, the level gauge sends a signal to sequentially activate the second conveyor 42, the first conveyor 41, and the anti-blocking device 5. The ore powder in the chamber falls onto the first conveyor 41, reducing the amount of ore powder and lowering the level. When the level reaches the minimum level in the chamber, the anti-blocking device 5, the first conveyor 41, and the second conveyor 42 are sequentially stopped, allowing the ore powder in the chamber to begin accumulating. Thus, the ore powder spilled from the skip first accumulates in the chamber, is then agitated by the anti-blocking device 5, and subsequently transported by the first conveyor 41 and the second conveyor 42 to the skip loading system and enters the skip's hoisting ore system (not shown). This achieves automatic cleaning and recovery of ore powder spilled from the skip shaft, with high production efficiency, no operators required, and reduced manpower.
