Description

Technical Field

[0001] The present invention belongs to the technical field of mineral processing, and in particular relates to a mineral processing shaking table multi-product intelligent ore receiving system and method. Background Art

[0002] Existing shaking table beneficiation technology has a long history. Since the late 19th and early 20th centuries, shaking tables have been used to separate gold, tin, tungsten, and other minerals. With technological advancements, these technologies have been expanded to process a wider range of ore types. Shaking table beneficiation is a process based on gravity separation. By utilizing density differences in mineral particles, vibration and stratification on a shaking table separate useful minerals from impurities. This technology still holds a vital position in modern mining, widely used in the separation of metal mines, heavy ores, lithium, and rare earth ores. In shaking table beneficiation, the ore zone fanns out diagonally from the feed end to the concentrate end. As the slurry passes through the bed, mineral particles of varying densities are affected by gravity and flushing water, forming multiple zones, ultimately achieving mineral separation.

[0003] However, the existing intelligent ore receiving device for a shaking table still has many shortcomings when sorting multiple products. First, after the spiral concentrate is sorted by the shaking table, tantalum-niobium concentrate is often separated, and the three separated products include concentrate, sub-concentrate and tailings. However, the existing ore receiving device is generally only for the reception of a single concentrate, and there is a lack of solutions that can receive concentrate, sub-concentrate and tailings at the same time, which limits the efficiency of mineral processing. In addition, the width of the ore receiving plate of the current device is not adjustable and cannot be dynamically adjusted according to the changes in the width of the ore belt, thereby affecting the effective collection and separation of minerals. The existing technology uses control lines, resulting in a large number of cables, especially when multiple shaking tables are configured in the beneficiation plant, which increases the complexity and workload of construction and maintenance. In addition, the existing solution only completes the preliminary reception of the concentrate, fails to achieve the effective collection of concentrates from multiple shaking tables, and does not further centrally manage the concentrate flow, thereby limiting the integration and efficiency of the entire mineral processing system.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the present invention.

[0035] In addition, described feature, structure or characteristic can be combined in one or more embodiments in any suitable manner.In the following description, many specific details are provided so as to provide a full understanding of the embodiments of the present application. However, it will be appreciated by those skilled in the art that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps etc. can be adopted. In other cases, known methods, devices, implementations or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0036] like Figure 1-6As shown, this embodiment discloses a multi-product intelligent ore receiving system for a mineral processing shaking table, including a shaking table 3 and an intelligent ore receiving device. The shaking table 3 is equipped with a secondary concentrate chute 1 and a tailings chute 2, respectively, for receiving and separating secondary concentrate and tailings from the ore belt. The shaking table 3 uses gravity differences to separate mineral particles of different densities through a set angle and vibration frequency, with the secondary concentrate flowing into the secondary concentrate chute 1 and the tailings flowing into the tailings chute 2, thereby achieving a preliminary separation effect. The intelligent ore receiving device includes a tailings conveyor trough 4, a receiving tray 5, a concentrate conveyor trough 6, a support frame 7, an intelligent ore receiving device box 8, a camera 9, and a camera bracket 10. The tailings conveyor trough 4 is used to collect tailings and discharge them into the tailings chute 2, while the concentrate conveyor trough 6 is used to convey the concentrate to the concentrate collection system or further processing unit. One end of the support frame 7 is mounted on one side of the tailings chute 2, and the other end is mounted within the secondary concentrate chute 1. The support frame 7 provides stable support, allowing the intelligent ore receiving device to be stably installed and preventing the ore receiving device from shifting due to vibration. The tailings conveyor trough 4 and the concentrate conveyor trough 6 are placed on the support frame 7 and can slide along it to adjust the conveying position. This sliding design facilitates adjusting the position of the conveyor trough according to the distribution of the ore belt and the amount of ore, optimizing the collection path of tailings and concentrate, and improving ore receiving efficiency. The ore receiving tray 5 includes a concentrate receiving tray 11, a receiving tray support frame 12, a calibration pipe 13, and a secondary concentrate receiving tray. The concentrate receiving tray 11 is fixed to the receiving tray support frame 12 and is used to collect a fixed width of concentrate belt. The secondary concentrate receiving tray is mounted to the side of the concentrate receiving tray 11 to maintain relatively independent spaces when receiving the concentrate and secondary concentrate, preventing mineral mixing. Calibration tube 13 is used to calibrate the position of receiving tray 5 and the width of the ore belt to ensure that the concentrate and sub-concentrate are accurately collected in their respective receiving trays. Intelligent receiving device box 8 is mounted above support frame 7. Camera bracket 10, located above intelligent receiving device box 8, is used to mount camera 9. Camera 9 captures images of the ore belt distribution on shaking table 3 and transmits these images to the control device for analysis, allowing real-time adjustment of the position and width of receiving tray 5 to improve sorting accuracy and mineral recovery rate.

[0037] In this embodiment, the bottom of the secondary concentrate chute 1 and the tailings chute 2 are provided with openings to facilitate the discharge of minerals. The secondary concentrate receiving tray includes a motor 14, a water baffle 15, a camera fixture 16, a coupling 17, a movable plate 18, a fixed block 19 and a bearing 20. The bearing 20 is mounted on the receiving tray support frame 12 and is used to provide a stable rotation fulcrum for the movable plate 18 so that the movable plate 18 remains stable during the adjustment process. The fixed block 19 is connected to the movable plate 18 by screws, and the fixed block 19 is firmly connected to the movable plate 18 to ensure that the movable plate 18 does not deviate during rotation. The motor 14 is connected to the rotating shaft of the movable plate 18 through the coupling 17, so that the rotational force of the motor 14 can be directly transmitted to the movable plate 18, and the movable plate 18 is driven to rotate by the rotation of the motor shaft, thereby flexibly adjusting the receiving width of the secondary concentrate receiving tray to adapt to the requirements of different ore belt widths and improve the accuracy and efficiency of mineral collection.

[0038] like Figure 4 As shown, the intelligent ore receiving device box 8 further includes a ore receiving box fixed angle steel 21, a lower cover plate 22, an ore receiving box frame 23, a slide module 24, an embedded development board 25, an upper cover plate 26, a connecting block 27, a drag chain 28, and a drag chain slot 29. The upper end of the ore receiving box fixed angle steel 21 is connected to the ore receiving box frame 23 by screws. The upper cover plate 26 and the lower cover plate 22 are also screwed to the ore receiving box frame 23, forming an enclosed space that protects the internal slide module 24 and embedded development board 25 from external environmental influences. One end of the connecting block 27 is connected to the ore receiving tray 5, and the other end is fixed to the slide module 24 by screws, enabling the slide module 24 to drive the ore receiving tray 5 along the slide rail. The movement of the slide module 24 allows the position of the ore receiving tray 5 to be adjusted to accommodate the location of different ore belts. A drag chain slot 29 is fixed to the receiving box frame 23. One end of the drag chain 28 is screwed to the connecting block 27, and the other end is fixed in the drag chain slot 29. This structure allows the drag chain 28 to move synchronously with the movement of the slide module 24, preventing the connecting cable from being pulled or damaged during movement and ensuring stable operation. An embedded development board 25 is fixed to one side of the receiving box frame 23. As the core component of the control device, it is used to receive and process image information from the camera 9 and control the operation of components such as the motor 14 and the slide module 24, realizing intelligent ore receiving control.

[0039] Furthermore, the support frame 7 is provided with threaded holes, which can be fixed with screws. The threaded hole and screw connection design ensures that the support frame 7 has high stability during installation, can withstand the vibration and load during equipment operation, and prevents the bracket from loosening and affecting the ore receiving accuracy. The bottom of the intelligent ore receiving device box 8 is provided with an ore receiving box fixing angle steel 21, which is fixed to the side wall of the secondary concentrate chute 1 of the shaking table 3 with screws to ensure the stable installation position of the intelligent ore receiving device box 8.

[0040] like Figure 6 As shown, the ore dressing shaking table multi-product intelligent ore receiving system also includes a transmission box 30 and a concentrate collection pipe 35. The transmission box 30 is used for power transmission and control, supporting the movement and adjustment of the ore receiving plate 5 and other key components, so that the entire system can dynamically adjust the ore receiving position according to the position of the ore belt. The concentrate collection pipe 35 is used to collect the concentrates from multiple shaking tables 3 in a centralized manner, and to collect the concentrates from different sources into the same channel, so as to facilitate subsequent unified processing or further concentrate sorting. In one embodiment, the shaking tables 3 include four, namely shaking table 1 31, shaking table 2 32, shaking table 3 33 and shaking table 4 34. The four shaking tables work together in the same system, and the concentrates are collected in a centralized manner through the concentrate collection pipe 35, which can handle a larger amount of ore and achieve a higher mineral recovery rate and system operation efficiency. This arrangement of multiple shaking tables facilitates system expansion, while improving the overall ore dressing capacity, and is suitable for large-scale ore dressing operation environments.

[0041] like Figure 7-8 As shown, in this embodiment, the ore dressing shaking table multi-product intelligent ore receiving system also includes a control device, which is composed of a cloud server and an edge controller. An image recognition algorithm is deployed on the cloud server, which is responsible for identifying and analyzing the transmitted ore belt image, identifying the distribution of concentrate, sub-concentrate and tailings in the ore belt, and thus generating accurate control parameters. The edge controller is composed of an embedded development board 25, a motor 14 and a camera 9. The camera 9 is used to collect image information of the ore belt, capture the distribution of the ore belt on the shaking table 3 in real time, and provide this image information to the embedded development board 25 for further processing. The embedded development board 25 receives the image information collected by the camera 9 and uploads the image data to the cloud server via wireless means. After processing the image data, the cloud server outputs the recognition results, including the location, width and distribution boundaries of the ore belt.

[0042] The embedded development board 25 receives the recognition results from the cloud server and generates control instructions based on this data, sending these instructions to the motor 14 to achieve precise control. After receiving the instructions, the motor 14 drives the ore receiving plate 5 and the movable plate 18 to move to the designated ore belt position, allowing the ore receiving plate to accurately align with the concentrate or sub-concentrate area on the ore belt. This control process enables automatic adjustment of the ore receiving plate, improving the accuracy and efficiency of mineral collection while reducing manual intervention. Through wireless data transmission and cloud processing, the system not only improves control flexibility, but also reduces the number of cables in the ore receiving device, simplifying the system's construction and maintenance.

[0043] like Figure 9 As shown, in another embodiment, an intelligent ore receiving method based on the above-mentioned ore dressing shaking table multi-product intelligent ore receiving system is also disclosed, comprising the following steps:

[0044] S1, image acquisition: collect the distribution image of the mineral belt through the camera and transmit the image data to the embedded development board;

[0045] S2, data transmission: the embedded development board converts the collected image data into JSON format and transmits the JSON data to the cloud server through the website;

[0046] S3, ore belt identification and calculation: The cloud server receives and parses JSON data to identify the demarcation points of the ore belts, including the demarcation point s1 between the concentrate belt and the secondary concentrate belt, the demarcation point s2 between the secondary concentrate belt and the tailings belt, and the width s2-s1 of the secondary concentrate belt. Based on the identification results, the lateral movement distance of each receiving tray and the rotation angle of the secondary concentrate tray movable plate are calculated.

[0047] S4, return control instructions: The cloud server converts the calculation results into JSON data and transmits it back to the embedded development board through the website; the embedded development board decodes the data and generates corresponding control instructions;

[0048] S5, drive adjustment: The embedded development board sends control instructions to the drive motor of the slide module and the motor of the movable plate. The drive motor of the slide module controls the lateral movement of the ore receiving plate, so that the concentrate receiving plate and the secondary concentrate receiving plate are aligned with the boundary point between the concentrate belt and the secondary concentrate belt. The rotating motor of the movable plate adjusts the width of the secondary concentrate plate to the secondary concentrate belt width s2-s1;

[0049] S6, mineral separation: The concentrate receiving tray collects the concentrate and introduces it into the concentrate conveying chute, and then collects it into the concentrate collecting pipe; the secondary concentrate receiving tray collects the secondary concentrate and introduces it into the secondary concentrate chute of the shaking table; the tailings that are not collected flow into the tailings conveying chute and are discharged along the tailings chute, realizing the separation of the three products of concentrate, secondary concentrate and tailings.

[0050] Furthermore, the embedded development board uses Flask technology to encapsulate the image data into an http interface format and upload it to the cloud server to achieve data interaction with the cloud server.

[0051] In this embodiment, the multi-product intelligent ore connection method of the mineral processing shaking table solves the problem of traditional intelligent ore connection devices relying on a large number of control lines, resulting in a large number of cables, complex construction, and a heavy maintenance workload, through intelligent collaboration between the cloud and edge control. The image data of the ore belt collected by the camera is uploaded from the embedded development board to the cloud server via wireless transmission. The ore belt is accurately identified and positionally analyzed with the help of the cloud image recognition algorithm. The control instructions are then wirelessly transmitted back to the embedded development board to precisely adjust the position and width of the ore connection plate. This method does not rely on complex cable connections, which not only reduces construction and maintenance costs, but also improves the scalability and reliability of the system, providing an efficient solution for the intelligentization and digitization of mining equipment.

[0052] In summary, the present invention discloses a multi-product intelligent ore receiving system and method for a mineral processing shaking table, in which a concentrate receiving plate and a sub-concentrate receiving plate are provided to collect concentrate and sub-concentrate respectively. The concentrate is further collected into a concentrate collecting pipe, while the sub-concentrate enters a sub-concentrate chute, and the tailings are discharged through a tailings conveyor trough, thereby realizing the separation of the three products of concentrate, sub-concentrate and tailings. The sub-concentrate receiving plate is equipped with a motor-controlled movable plate, which automatically adjusts the receiving width according to the change of the ore belt width, thereby improving the accuracy and flexibility of the ore receiving operation. The system performs remote calculation of the recognition algorithm through a cloud server and realizes wireless interaction with an embedded development board, avoiding the limitations of traditional control lines and reducing the complexity of construction and maintenance. The invention is suitable for digital mining environments, providing an efficient and flexible mineral sorting solution, greatly improving the degree of automation and mineral processing efficiency of the system, and providing strong support for the construction of intelligent mines.
