Description

Technical Field

[0001] This invention relates to the field of underground mining technology for metals and non-metals, specifically to a fine ore bin at the bottom of a skip shaft. Background Technology

[0002] When the skip shaft hoists ore, fine ore will spill into the fine ore bin at the bottom of the shaft. Leaking water from the skip shaft shaft will also fall into the fine ore bin. As the leaking water and fine ore accumulate at the bottom of the shaft, the water level in the fine ore bin will rise higher and higher, even significantly higher than the top surface of the fine ore. In related technologies, the fine ore bin in the skip shaft is an integral fine ore bin, which is prone to safety accidents caused by excessive water pressure that could collapse the fine ore bin. 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 fine ore bin at the bottom of a skip shaft. This fine ore bin has low water pressure, is not easily crushed, and offers high safety and a long service life.

[0004] The skip shaft bottom ore bin of this invention includes:

[0005] A first compartment, the first compartment having a first chamber;

[0006] The second compartment has a second chamber. The first compartment and the second compartment are arranged vertically and the first chamber and the second chamber are connected. At least a portion of the first compartment is located in the second chamber.

[0007] An overflow trough is formed between at least a portion of the outer peripheral surface of the first chamber and the inner peripheral surface of the second chamber, and communicates with the first chamber and the second chamber.

[0008] The skip shaft bottom powder ore bin of this invention has a first bin body and a second bin body designed separately. When there is too much powder ore and water in the powder ore bin, the water can flow out through the overflow channel between the first bin body and the second bin body. This can effectively reduce the water pressure in the powder ore bin, eliminate the safety hazard of the powder ore bin being crushed, and improve the safety and service life of the skip shaft bottom powder ore bin of this invention.

[0009] In some embodiments, the bottom ore bin of the skip shaft further includes an overflow component, which is arranged circumferentially around the overflow trough and communicates with the overflow trough so that water in the overflow trough can flow into the overflow component.

[0010] In some embodiments, the bottom powder silo of the skip shaft further includes a connecting member that connects the overflow trough and the overflow member.

[0011] In some embodiments, there are multiple connecting elements, which are arranged circumferentially around the overflow trough.

[0012] In some embodiments, the dimension of the overflow trough in the circumferential direction is smaller than the dimension of the overflow trough in the vertical direction, and the circumferential direction is orthogonal to the vertical direction.

[0013] In some embodiments, the overflow trough has a dimension of 200mm to 300mm in the circumferential direction.

[0014] In some embodiments, the first compartment includes a first frame and first wall panels, the first wall panels being disposed around a perimeter and connected to the inner wall surface of the first frame, and the first chamber being formed between the first wall panels.

[0015] The second compartment includes a second frame and a second wall panel. The second wall panel is arranged around the perimeter and connected to the inner wall of the second frame. The second chamber is formed between the second wall panels.

[0016] In some embodiments, the first frame includes:

[0017] Multiple sets of first beam segments are arranged at intervals along the vertical direction, and each set of first beam segments includes two oppositely arranged first beam segments.

[0018] Multiple sets of second beam segments are arranged at intervals along the vertical direction. The multiple sets of second beam segments correspond one-to-one with multiple sets of first beam segments. Each set of second beam segments includes two oppositely arranged second beam segments. The two first beam segments in each set of first beam segments and the two second beam segments in each set of second beam segments are arranged alternately and connected end to end.

[0019] Multiple sets of first connecting beam segments are arranged at intervals along the vertical direction. Each set of first connecting beam segments is located between two adjacent sets of first beam segments and two adjacent sets of second beam segments. Each set of first connecting beam segments includes multiple first connecting beam segments. The multiple first connecting beam segments in each set are arranged at intervals around the first wall panel in the circumferential direction to connect two adjacent first beam segments and two adjacent second beam segments.

[0020] In some embodiments, the cross-sectional area of ​​the lower end of the first chamber is smaller than the cross-sectional area of ​​the upper end of the second chamber, and the overflow trough is formed between the outer peripheral surface of the lower end of the first wall panel and the inner peripheral surface of the upper end of the second wall panel.

[0026] 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.

[0027] like Figure 1-3 As shown, the bottom ore bin of the skip shaft in this embodiment of the invention includes a first bin body 1, a second bin body 2, and an overflow trough 3. The first bin body 1 has a first chamber 11, a first inlet 14, and a first outlet 15. The first inlet 14 and the first outlet 15 are connected to the first chamber 11. The first inlet 14 is formed on the top surface of the first bin body 1, and the first outlet 15 is formed on the bottom surface of the first bin body 1.

[0028] The second compartment 2 has a second chamber 21, a second inlet 24, and a second outlet 25. The second inlet 24 and the second outlet 25 communicate with the second chamber 21. The second inlet 24 is formed on the top surface of the second compartment 2, and the second outlet 25 is formed on the bottom surface of the second compartment 2. The first compartment 1 and the second compartment 2 are arranged vertically, and the first chamber 11 and the second chamber 21 communicate with each other. At least a portion of the first compartment 1 is located within the second chamber 21, and the central axis of the first compartment 1 is collinear with the central axis of the second compartment 2. Specifically, the first compartment 1 is located above the second compartment 2, and at least a portion of the lower end of the first compartment 1 extends into the upper end of the second compartment 2, so that the first outlet 15 communicates with the second inlet 24.

[0029] An overflow trough 3 is formed between at least a portion of the outer peripheral surface of the first chamber 1 and the inner peripheral surface of the second chamber 2, and communicates with the first chamber 11 and the second chamber 21. Specifically, there is a space between the lower outer peripheral surface of the first chamber 1 and the upper inner peripheral surface of the second chamber 2, and the overflow trough 3 is formed within the space.

[0030] The skip shaft bottom powder ore bin of this invention has a first bin body 1 and a second bin body 2 designed separately. The first bin body 1 and the second bin body 2 are installed and fixed on the skip shaft shaft 6 using steel structure beams. When there is too much powder ore and water in the powder ore bin and it reaches the overflow trough 3, the water can flow out through the overflow trough 3 between the first bin body 1 and the second bin body 2. This can effectively reduce the water pressure in the powder ore bin, eliminate the safety hazard of the powder ore bin being crushed, and improve the safety and service life of the skip shaft bottom powder ore bin of this invention.

[0031] Specifically, the seepage water from the skip shaft 6 falls into the powder ore bin at the bottom of the shaft, and the powder ore scattered from the skip also falls into the powder ore bin at the bottom of the shaft. The accumulated water fills the gaps in the powder ore, and the powder ore and seepage water accumulate more and more in the powder ore bin. When the powder ore accumulates to the overflow trough 3 at the junction of the upper end of the second bin 2 and the lower end of the first bin 1, the second chamber 21 of the second bin 2 is basically filled with powder ore. If powder ore continues to be scattered, the powder ore will accumulate in the first chamber 11 of the first bin 1, instead of falling into the overflow trough 3. After the powder ore bin is full, the powder ore is then recovered using powder ore recovery equipment.

[0032] In some embodiments, the bottom ore bin of the skip shaft also includes an overflow component 4, which is arranged circumferentially around the overflow trough 3. The overflow component 4 is connected to the overflow trough 3 so that water in the overflow trough 3 can flow into the overflow component 4 and then flow out, thereby reducing the water in the overflow trough 3, reducing the water pressure in the overflow trough 3, expanding the capacity of the overflow trough 3, and allowing the accumulated water in the ore bin to flow back into the overflow trough 3. Thus, the water pressure in the ore bin can be continuously reduced.

[0033] In some embodiments, the bottom ore bin of the skip shaft also includes a connecting member 5, which connects the overflow trough 3 and the overflow member 4.

[0034] Specifically, the connecting piece 5 is located outside the overflow trough 3 and connects the overflow trough 3 and the overflow piece 4. When the water level in the ore powder bin rises to the position of the overflow trough 3, water begins to accumulate in the overflow trough 3. As the leaking water continues to fall in, the water level in the overflow trough 3 rises. When it rises to the connecting piece 5, the accumulated water begins to flow out through the connecting piece 5 into the overflow piece 4. The overflow trough 3, the connecting piece 5, and the overflow piece 4 operate on the principle of communicating vessels, making it difficult for the water level in the ore powder bin to rise further, thus preventing the ore powder bin from being crushed.

[0035] In some embodiments, there are multiple connecting members 5, which are arranged circumferentially around the overflow tank 3, so that water in the overflow tank 3 can flow into the overflow member 4 with high efficiency.

[0036] In some embodiments, the size of the overflow trough 3 in the circumferential direction is smaller than the size of the overflow trough 3 in the vertical direction. The circumferential direction is orthogonal to the vertical direction. This not only makes it difficult for the powdered ore accumulated at the junction of the upper end of the second chamber 2 and the lower end of the first chamber 1 to enter the overflow trough 3, but also makes it easier to increase the water level in the overflow trough 3, thereby facilitating the formation of a communication device with the connecting member 5 and the overflow member 4.

[0037] Preferably, the overflow trough 3 has a circumferential dimension of 200mm to 300mm.

[0038] In some embodiments, the first compartment 1 includes a first frame 12 and a first wall panel 13. The first wall panel 13 is arranged around the perimeter and connected to the inner wall surface of the first frame 12, and a first chamber 11 is formed between the first wall panels 13. Specifically, the cross-sectional area of ​​the first compartment 1 gradually decreases from the upper end to the lower end of the first compartment 1 in the vertical direction.

[0039] The second compartment 2 includes a second frame 22 and a second wall panel 23. The second wall panel 23 is arranged around the perimeter and connected to the inner wall of the second frame 22. The second chamber 21 is formed between the second wall panels 23. Specifically, the cross-sectional area of ​​the second compartment 2 gradually decreases from the upper end to the lower end of the second compartment 2 in the vertical direction.

[0040] In some embodiments, 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, allowing the lower end of the first silo 1 to extend into the upper end of the second silo 2. This results in the overflow trough 3 being formed between the outer peripheral surface of the lower end of the first wall panel 13 and the inner peripheral surface of the upper end of the second wall panel 23. Thus, the first silo 1 and the second silo 2 form an inverted conical and separate powder ore silo, into which seepage water from the shaft 6 and powder ore scattered from the skip are collected.

[0041] In some embodiments, the first frame 12 includes multiple sets of first beam segments 121, multiple sets of second beam segments 122, and multiple sets of first connecting beam segments 123. The multiple sets of first beam segments 121 are arranged at intervals in the vertical direction, and each set of first beam segments 121 includes two opposing first beam segments 121.

[0042] Multiple sets of second beam segments 122 are arranged at intervals along the vertical direction, corresponding one-to-one with multiple sets of first beam segments 121. Each set of second beam segments 122 includes two opposing second beam segments 122. The two first beam segments 121 in each set of first beam segments 121 and the two second beam segments 122 in each set of second beam segments 122 are arranged alternately and connected end to end, forming a square space to form a first layer beam. Thus, multiple sets of first beam segments 121 and multiple sets of second beam segments 122 can form multiple first layer beams, which enclose an inverted pyramidal space. The central axis of the inverted pyramidal space is collinear with the central axis of the shaft 6. The first wall panel 13 is continuously laid on the inner side of the first layer beams and is connected to the first layer beams as a whole. The setting of the first layer beams enhances the structural stability of the first chamber 11 enclosed by the first wall panel 13.

[0043] Multiple sets of first connecting beam segments 123 are arranged at intervals in the vertical direction. Each set of first connecting beam segments 123 is located between two adjacent sets of first beam segments 121 and two adjacent sets of second beam segments 122. Each set of first connecting beam segments 123 includes multiple first connecting beam segments 123. The multiple first connecting beam segments 123 in each set of first connecting beam segments 123 are arranged at intervals around the first wall panel 13 in the circumferential direction to connect two adjacent first beam segments 121 and two adjacent second beam segments 122.

[0044] Specifically, a set of first connecting beam segments 123 is provided between two adjacent first-layer beams to connect the two adjacent first-layer beams, thereby improving the structural strength and rigidity of the first frame 12 and making the structure of the first compartment 1 more robust.

[0045] In some embodiments, the second frame 22 includes multiple sets of third beam segments 221, multiple sets of fourth beam segments (not shown), and multiple sets of second connecting beam segments 222. The multiple sets of third beam segments 221 are arranged at intervals in the vertical direction, and each set of third beam segments 221 includes two opposing third beam segments 221.

[0046] Multiple sets of fourth beam segments are arranged at intervals along the vertical direction, corresponding one-to-one with multiple sets of third beam segments 221. Each set of fourth beam segments includes two opposing fourth beam segments. The two third beam segments 221 within each set of third beam segments 221 and the two fourth beam segments within each set of fourth beam segments are arranged alternately and connected end to end, forming a square space to create a second layer of beams. Thus, multiple sets of third beam segments 221 and multiple sets of fourth beam segments can form multiple second layers of beams, which enclose an inverted pyramidal space. The central axis of the inverted pyramidal space enclosed by the second layer of beams is collinear with the central axis of the inverted pyramidal space enclosed by the first layer of beams. The second wall panel 23 is continuously laid on the inner side of the second layer of beams and is integrated with the second layer of beams. The arrangement of the second layer of beams enhances the structural stability of the second chamber 21 enclosed by the second wall panel 23.

[0047] Multiple sets of second connecting beam segments 222 are arranged at intervals in the vertical direction. Each set of second connecting beam segments 222 is located between two adjacent sets of third beam segments 221 and two adjacent sets of fourth beam segments. Each set of second connecting beam segments 222 includes multiple second connecting beam segments 222. The multiple second connecting beam segments 222 in each set of second connecting beam segments 222 are arranged at intervals around the second wall panel 23 in the circumferential direction to connect two adjacent third beam segments 221 and two adjacent fourth beam segments.

[0048] Specifically, a set of second connecting beam segments 222 is provided between two adjacent second-layer beams to connect the two adjacent second-layer beams, thereby improving the structural strength and rigidity of the second frame 22 and making the structure of the second compartment 2 more robust.

[0049] In some embodiments, the bottom ore bin of the skip shaft also includes a water collection pool (not shown), which is connected to the overflow component 4.

[0050] Specifically, the water accumulated in the overflow component 4 can flow into the collection pool, and any subsequent leakage water falling into the ore powder bin will flow into the collection pool through the overflow trough 3, the connecting component 5, and the overflow component 4 in sequence. This not only prevents the water level in the ore powder bin at the bottom of the well from rising, but also collects the accumulated water in the ore powder bin in a unified manner, thus purifying the working environment.
