Description

Technical Field

[0001] This invention relates to the field of concentrate storage management, and more specifically to a concentrate storage system. Background Technology

[0002] In the storage and transportation of concentrate powder in ore dressing plants, the rationality of the ore loading scheme directly affects production efficiency and investment economics. Currently, the industry mainstream adopts two schemes: ore bin type and ore pile type. Among them, the ore bin type ore loading scheme uses the gravity of the concentrate powder to achieve gravity-flow loading, which can save additional loading power equipment and has the characteristics of simple loading process; the ore pile type ore loading scheme has the large storage capacity as its core advantage, which can adapt to the large-scale storage needs of concentrate powder, and the loading operation is usually completed by front-loading machine or grab crane.

[0003] However, both of the above-mentioned existing solutions have significant technical defects and are difficult to meet the needs of efficient and economical storage and transportation under complex working conditions. Specifically, the ore bin-type ore storage and loading solution has the inherent disadvantage of short ore storage time. When applied to concentrators with harsh surrounding traffic environments, long transportation distances, and large concentrate outputs, a large number of ore bins need to be built to form a ore bin cluster in order to ensure continuous production and stable loading. This will significantly increase the amount of infrastructure investment, resulting in high project construction costs and seriously affecting the economic viability of the solution. Although the ore pile-type ore storage and loading solution solves the problem of insufficient ore storage, it is limited by the loading operation method and requires a lot of manpower to operate the equipment. This not only increases labor costs but also has the problem of low operating efficiency. Moreover, it is difficult to achieve automated and intelligent control of the loading process, and it cannot adapt to the high-efficiency production development needs of modern concentrators.

[0004] Therefore, the ore bin-type ore storage and loading scheme in related technologies suffers from high infrastructure investment, while the ore pile-type ore storage and loading scheme suffers from low automation. There is an urgent need to propose an optimized scheme that takes into account ore storage capacity, loading efficiency, and investment economy. Summary of the Invention

[0005] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, this invention provides a concentrate storage system.

[0006] The concentrate storage system of this invention includes a production area, an elevated ore storage area and a buffer storage area arranged sequentially along a first direction, a first conveying component and a second conveying component.

[0007] The first conveying component extends through the elevated ore bin area in the first direction, and a feeder is provided on the first conveying component located in the elevated ore bin area; one end of the first conveying component is located in the production area, and the other end of the first conveying component is located in the buffer storage area.

[0008] One end of the second conveying component is located in the buffer storage area, and the other end of the second conveying component is located above the first conveying component, with the other end of the second conveying component located between the production area and the elevated ore storage area.

[0009] The concentrate storage system of this invention consists of a production area, an elevated ore bin area, and a buffer storage area arranged sequentially in a first direction, along with a first conveying component and a second conveying component. After the concentrate is collected from the production area, it passes through the first conveying component to the elevated ore bin area. Under the action of the feeder, the concentrate is unloaded into the elevated ore bin area for loading. When the concentrate in the elevated ore bin area is full, the feeder stops working, and the concentrate is conveyed to the buffer storage area by the first conveying component.

[0010] When there is a shortage of concentrate in the elevated ore bin area, the concentrate in the buffer storage area can be transferred to the elevated ore bin area for loading through the second conveying component. Specifically, the concentrate is transported from the buffer storage area to the first conveying component under the action of the second conveying component, and then transported to the elevated ore bin area for loading by the first conveying component.

[0011] The concentrate storage system of this invention can achieve the following significant technical effects: Firstly, through the hierarchical storage design of "elevated mining warehouse area + cache storage area", there is no need to build a large-scale mining warehouse cluster, and the construction standard of the cache storage area is lower, effectively solving the problem of high infrastructure investment in traditional mining warehouse solutions. Secondly, by relying on the collaboration of dual conveyor components and feeders, the entire process of concentrate "mining-transfer-storage-loading-return" is fully automated, eliminating reliance on manual labor and solving the problems of high labor costs and low efficiency in traditional stockpile solutions; Third, the flow of concentrate can be dynamically adjusted according to the storage status of the elevated ore storage area to ensure continuous operation and balance storage capacity and loading efficiency. Fourth, it retains the convenience of gravity-fed loading of elevated ore bins while making up for the shortcomings of insufficient ore storage capacity in traditional elevated ore bin solutions.

[0012] Therefore, the concentrate storage system of this invention can greatly reduce the construction cost of the elevated ore storage area, and at the same time, the concentrate in the buffer storage area can also realize automated loading operations.

[0024] 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.

[0025] The following is in conjunction with the appendix Figures 1-6 The concentrate storage system of this invention will be described in detail.

[0026] The concentrate storage system of this invention includes a production area 1, an elevated ore storage area 2, a buffer storage area 3, a first conveying component 4, and a second conveying component 5 arranged sequentially along a first direction.

[0027] The first conveying component 4 passes through the elevated ore storage area 2 along the first direction, and a feeder 202 is provided on the first conveying component 4 located in the elevated ore storage area 2; one end of the first conveying component 4 is located in the production area 1, and the other end of the first conveying component 4 is located in the buffer storage area. One end of the second conveying component 5 is located in the buffer storage area 3, and the other end of the second conveying component 5 is located above the first conveying component 4, and the other end of the second conveying component 5 is located between the production area 1 and the elevated ore storage area 2.

[0028] The concentrate storage system of this invention consists of a production area 1, an elevated ore storage area 2, and a buffer storage area 3 arranged sequentially in a first direction, along with a first conveying component 4 and a second conveying component 5. After the concentrate is collected from the production area 1, it passes through the first conveying component 4 to the elevated ore storage area 2. Under the action of the unloader 202, the concentrate is unloaded into the elevated ore storage area 2 for loading. When the concentrate in the elevated ore storage area 2 is full, the unloader 202 stops working, and the concentrate is conveyed by the first conveying component 4 to the buffer storage area 3.

[0029] When there is a shortage of concentrate in the elevated ore storage area 2, the concentrate in the buffer storage area 3 can be transferred to the elevated ore storage area 2 for loading through the second conveying component 5. Specifically, the concentrate is transported from the buffer storage area 3 to the first conveying component 4 under the action of the second conveying component 5, and then transported to the elevated ore storage area 2 for loading by the first conveying component 4.

[0030] The concentrate storage system of this invention can achieve the following significant technical effects: Firstly, through the hierarchical storage design of "elevated mining warehouse area 2 + cache storage area 3", there is no need to build a large-scale mining warehouse cluster. The construction standard of cache storage area 3 is lower, which effectively solves the problem of high infrastructure investment in traditional mining warehouse solutions. Secondly, relying on the collaboration of the dual conveyor components and the feeder 202, the entire process of concentrate "mining-transfer-storage-loading-return" is fully automated, eliminating reliance on manual labor and solving the problems of high labor costs and low efficiency in traditional stockpile solutions; Third, the flow of concentrate can be dynamically adjusted according to the storage status of the elevated ore storage area 2 to ensure continuous operation and balance storage capacity and loading efficiency. Fourth, it retains the convenience of gravity-fed loading of the 201-type elevated ore bin, while making up for the shortcoming of insufficient ore storage capacity in the traditional 201-type elevated ore bin scheme.

[0031] Therefore, the concentrate storage system of this invention can greatly reduce the construction cost of the elevated ore storage area 2, and at the same time, the concentrate in the buffer storage area 3 can also achieve automated loading operations.

[0032] In some embodiments, the first conveying assembly 4 includes a first conveyor belt 401, a second conveyor belt 402, and a third conveyor belt 403; one end of the first conveyor belt 401 is located in the production area 1, the other end of the first conveyor belt 401 is located above one end of the second conveyor belt 402, the second conveyor belt 402 is located in the elevated ore bin area 2, the other end of the second conveyor belt 402 is located above one end of the third conveyor belt 403, and the other end of the third conveyor belt 403 is located in the buffer storage area 3.

[0033] It is understandable that the feeder 202 is located on the second conveyor belt 402 and can feed the concentrate on the second conveyor belt 402 to the elevated ore bin area 2.

[0034] On the one hand, the segmented conveyor belt design can flexibly adapt to the site elevation difference and layout requirements of production area 1, elevated ore storage area 2, and buffer storage area 3, reducing the installation difficulty of the overall conveying system. Compared with integrated long-distance conveyor belts, the segmented structure is more convenient for later maintenance and local repairs. On the other hand, the feeder 202 is precisely positioned on the second conveyor belt 402 of the corresponding elevated ore bin area 2, which can realize the directional unloading of concentrate to the elevated ore bin area 2 and avoid concentrate spillage and waste. In addition, the segmented conveyor structure allows each section of the conveyor belt to be matched with the appropriate power according to the needs of the corresponding operation, avoiding energy waste caused by the integrated conveyor belt operating at high power throughout the entire process.

[0035] In some embodiments, the elevated mining area 2 includes a plurality of elevated mining bins 201 arranged sequentially along a first direction. The upper end of the elevated mining bin 201 is provided with a feed inlet 2011, and the lower end of the elevated mining bin 201 is provided with a discharge outlet. A second conveyor belt 402 is arranged above the plurality of elevated mining bins 201, and a discharge device 202 is provided on the second conveyor belt 402 corresponding to the elevated mining bin 201.

[0036] Optionally, the feeder 202 may be a plow-type unloader, and a valve may be installed at the first discharge port 2012 to facilitate opening and closing of the first discharge port 2012, for example, a flat gate valve may be installed at the first discharge port 2012.

[0037] like Figures 1-6As shown, there are multiple elevated ore bins 201, and each of the multiple elevated ore bins 201 is equipped with a feeder 202 on the second conveyor belt 402. That is to say, each elevated ore bin 201 has a corresponding feeder 202. At the same time, the number of feeders 202 corresponding to each elevated ore bin 201 can be one or more, thereby achieving the effect of single-point unloading or multi-point unloading. It can be understood that the specific number can be set according to actual needs.

[0038] The feeder 202 feeds the concentrate from the second conveyor belt 402 to the feed port of its corresponding elevated ore bin 201. In other words, when an elevated ore bin 201 needs to be fed, only its corresponding feeder 202 needs to be turned on.

[0039] Meanwhile, the elevated mine storage area 2 can also be equipped with mine storage supports to support multiple elevated mine storage areas 201.

[0040] It is understandable that parking spaces can be set up in the area corresponding to the unloading port on the ground of the elevated ore bin 2, so that transfer vehicles can be parked under the elevated ore bin 201 for loading.

[0041] By equipping each elevated ore bin 201 with a dedicated feeder 202, the unloading of materials into a single ore bin can be precisely controlled, preventing the mixing or misloading of concentrates. This facilitates the separate storage of different batches and types of concentrates. Even if one elevated ore bin 201 or its corresponding feeder 202 malfunctions, it will not affect the normal operation of other ore bins, ensuring that the entire ore storage and loading process is uninterrupted and improving the reliability of the system.

[0042] In some embodiments, the other end of the third conveyor belt 403 is movable in its length direction.

[0043] Optionally, the other end of the third conveyor belt 403 may be movable in the first direction.

[0044] It is understandable that the other end of the third conveyor belt 403 is located in the buffer stockpile area 3. By setting the other end of the third conveyor belt 403 to be movable in the first direction, it is convenient for the concentrate to form a concentrate stockpile that extends in the first direction in the buffer stockpile area 3.

[0045] like Figure 1 As shown, the concentrate pile in the buffer storage area 3 extends along the first direction within the buffer storage area 3.

[0046] Therefore, by making the other end of the third conveyor belt 403 movable in its length direction, firstly, the concentrate can be evenly extended and piled in the buffer stockpile area 3 along the length direction of the third conveyor belt 403, avoiding excessive accumulation of concentrate in a single location, making full use of the site space of the buffer stockpile area 3, and increasing the overall storage capacity of the buffer stockpile area 3; secondly, the orderly extended stockpile shape can facilitate the subsequent grabbing and return conveying of concentrate by the second conveying component 5, reducing conveying blockages caused by messy stockpiling, and ensuring the smoothness of return operations; thirdly, the stockpile position can be flexibly adjusted according to the actual spatial distribution of the buffer stockpile area 3, adapting to buffer stockpiles of different sizes, and improving the system's adaptability to the site.

[0047] In some embodiments, the second conveying assembly 5 includes a first transfer conveyor belt 501, a second transfer conveyor belt 502, and a third transfer conveyor belt 503; the first transfer conveyor belt 501 is located below the buffer storage area 3, and one end of the first transfer conveyor belt 501 is located above the second transfer conveyor belt 502; a second discharge port 301 is provided at the bottom of the buffer storage area 3 corresponding to the first transfer conveyor belt 501; one end of the second transfer conveyor belt 502 is located in the buffer storage area, and the other end of the second transfer conveyor belt 502 is located above one end of the third transfer conveyor belt 503, and the other end of the third transfer conveyor belt 503 is located above the first conveyor belt 401.

[0048] It is understandable that by configuring the second conveying component 5 to include the first transfer conveyor belt 501, the second transfer conveyor belt 502, and the third transfer conveyor belt 503, the second conveying component 5 is designed as a segmented transfer system. On one hand, the segmented transfer design can precisely adapt to the site layout and elevation difference between the buffer stockpile area 3 and the first conveyor belt 401, making the return path of the concentrate from the buffer stockpile area 3 to the first conveyor belt 401 more reasonable and reducing the overall installation difficulty of the conveying system. On the other hand, the second discharge port 301 at the bottom of the buffer stockpile area 3, in conjunction with the first transfer conveyor belt 501 below, can achieve directional discharge and stable reception of the concentrate, avoiding spillage or accumulation of concentrate in the initial stage of return flow and ensuring the smoothness of the return start point. Furthermore, each segment of the transfer conveyor belt can be matched with its own power according to its conveying task, avoiding the integrated transfer belt from operating at high power throughout the entire process, further achieving energy saving and consumption reduction, and lowering operating costs.

[0049] In some embodiments, there are multiple second discharge ports 301, and the multiple second discharge ports 301 are spaced apart along the extension direction of the first transfer conveyor belt 501.

[0050] Optionally, the extension direction of the first transfer conveyor belt 501 may be perpendicular to the length direction of the third conveyor belt 403.

[0051] It is understandable that a valve can be installed at the second discharge port 301 to facilitate opening and closing of the second discharge port 301, for example, a flat gate valve can be installed at the second discharge port 301.

[0052] like Figure 3 As shown, the first transfer conveyor belt 501 extends along the second direction, and the second direction is perpendicular to the first direction. That is to say, multiple second discharge ports 301 are spaced apart along the second direction, which is perpendicular to the first direction.

[0053] By setting multiple second discharge ports 301, which can be opened simultaneously or selectively, the concentrate can be evenly distributed onto the first transfer conveyor belt 501, preventing excessive local accumulation of concentrate on the conveyor belt and ensuring the stability of subsequent transfer. This also increases the conveying capacity of the first transfer conveyor belt 501 per unit time. Furthermore, the spaced second discharge ports 301 in the second direction perpendicular to the first direction can precisely correspond to different areas of material accumulation, making fuller use of the ore storage space in the buffer stockpile area 3 and preventing unrecoverable local material residue. Additionally, the number and frequency of opening each discharge port can be flexibly adjusted according to the load of the first transfer conveyor belt 501, achieving precise control of the concentrate conveying capacity, adapting to different reflux requirements, and improving the operational flexibility of the reflux system.

[0054] In some embodiments, there are multiple first transfer conveyor belts 501, and the multiple first transfer conveyor belts 501 are spaced apart in the length direction of the third conveyor belt 403.

[0055] It is understandable that each of the multiple first transfer conveyor belts 501 can correspond to a set of spaced second discharge ports 301, forming multiple sets of parallel return conveying channels, which greatly improves the overall return efficiency of concentrate from the buffer stockpile area 3 and adapts to the large-scale concentrate return demand; at the same time, the multiple first transfer conveyor belts 501 can operate or start and stop independently. If a transfer conveyor belt fails, it only affects the return operation in the corresponding area, while other conveyor belts can still work normally, which significantly improves the fault tolerance and operational stability of the return system; in addition, the load of each transfer conveyor belt can be flexibly allocated according to the amount of stockpile in each area, and the balanced scheduling of concentrate return can be achieved by adjusting the opening status of the corresponding discharge ports, avoiding overload operation of a single conveyor belt and extending the service life of the equipment.

[0056] In some embodiments, the concentrate storage system of the present invention further includes a fourth conveyor belt 404, the other end of the third conveyor belt 403 is disposed above the fourth conveyor belt 404, and both ends of the fourth conveyor belt 404 are movable in its length direction.

[0057] It is understood that the fourth conveyor belt 404 is located in the buffer stockpile area 3, and both ends of the fourth conveyor belt 404 are movable in its length direction. By setting both ends of the fourth conveyor belt 404 to be movable in its length direction, it is convenient for the concentrate to form a concentrate stockpile in the buffer stockpile area 3 that extends in its length direction.

[0058] like Figure 4 As shown, the concentrate pile in the buffer storage area 3 extends along the second direction within the buffer storage area 3.

[0059] Understandably, by making both ends of the fourth conveyor belt 404 movable along its length, the concentrate can be evenly distributed and piled in the buffer stockpile area 3 along the length of the fourth conveyor belt 404, making full use of the space in the buffer stockpile area 3 along the length of the fourth conveyor belt 404 and significantly increasing the storage capacity of the buffer stockpile area 3. Simultaneously, the design that both ends of the fourth conveyor belt 404 can move along its length allows for flexible adjustment of the coverage area of ​​the stockpile along the length of the fourth conveyor belt 404, adapting to buffer stockpiles of different sizes and shapes, greatly improving the system's adaptability to different sites; and also... The regular, extended stacking pattern of the fourth conveyor belt 404 avoids problems such as excessive local height or uneven distribution caused by messy accumulation of concentrate, ensuring the stability of the stack. At the same time, it facilitates the smooth grabbing and recirculation of concentrate by the second conveyor component 5, reducing conveying jams. Furthermore, by adjusting the moving speed of the fourth conveyor belt 404 and the unloading rate of the third conveyor belt 403, the thickness and uniformity of the stacking along the length of the fourth conveyor belt 404 can be precisely controlled to adapt to different recirculation conveying requirements and improve the synergistic efficiency of ore storage and recirculation in the buffer stockpile area 3.

[0060] In some embodiments, the second conveying assembly 5 includes a fourth transfer conveyor belt 504, a fifth transfer conveyor belt 505, and a sixth transfer conveyor belt 506. The fourth transfer conveyor belt 504 is located in the buffer storage area 3 and extends in a second direction. One end of the fifth transfer conveyor belt 505 is located in the buffer storage area 3 and is located below one end of the fourth transfer conveyor belt 504. The other end of the fifth transfer conveyor belt 505 is located above one end of the sixth transfer conveyor belt 506, and the other end of the sixth transfer conveyor belt 506 is located above the first conveyor belt 401.

[0061] It is understandable that by setting the fourth transfer conveyor belt 504 to extend along the length of the fourth conveyor belt 404, it can precisely match the regular stockpile shape of the buffer stockpile area 3 along the length of the fourth conveyor belt 404. This allows for the smooth reception and transfer of the stockpile along the length of the fourth conveyor belt 404, avoiding spillage or jamming caused by the inconsistency between the stockpile extension direction and the conveying direction, and ensuring the smoothness of the return flow starting point. At the same time, the segmented design of the fourth, fifth, and sixth transfer conveyor belts can accurately adapt to the site elevation difference and layout between the buffer stockpile area 3 and the first conveyor belt 401, making the return flow path more reasonable and reducing the installation difficulty of the overall conveying system. Furthermore, the operating status of the fourth transfer conveyor belt 504 can be flexibly adjusted according to the stockpile volume in different areas of the buffer stockpile area 3 along the length of the fourth conveyor belt 404. Combined with the speed control of the fifth and sixth transfer conveyor belts, this achieves balanced scheduling of concentrate return, avoids overloading of a single section of the conveyor belt, and improves the overall return flow efficiency, thereby adapting to the needs of large-scale concentrate return.

[0062] In some embodiments, the second conveying assembly 5 further includes a material reclaimer 6, which is movable along the length of the fourth conveyor belt 404. The material reclaimer 6 has a material reclaiming component 601 and a feeding port 602. The material reclaiming component 601 is used to reclaim material, and the feeding port 602 is used to deliver the material reclaimed by the material reclaiming component 601. The feeding port 602 is located above the fourth transfer conveyor belt 504. The material reclaimer 6 is prior art, and its specific structure will not be described in detail.

[0063] The material handling machine 6 can be placed on the guide rail 603, which extends along the length of the fourth conveyor belt 404, so that the material handling machine 6 can move along the length of the fourth conveyor belt 404.

[0064] Understandably, by setting the reclaimer 6 to be movable along the length of the fourth conveyor belt 404, the material reclaiming can accurately correspond to the material piles in each area of ​​the buffer storage area 3 extending along the length of the fourth conveyor belt 404, achieving full-range material reclaiming without dead angles, completely solving the problem of unrecoverable local material pile residue, and further improving the space utilization rate of the buffer storage area 3; at the same time, the reclaimer 6 can independently adjust its moving speed and material reclaiming rate, and can flexibly adapt the material reclaiming rhythm according to the material pile volume in different areas of the buffer storage area 3; in addition, the guide rail 603 enables the smooth movement of the reclaimer 6, avoiding equipment shaking during the material reclaiming process, improving the safety of the material reclaiming operation and the service life of the equipment.
