Description

Technical Field

[0001] The 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] The existing shaking table beneficiation technology has a long history. Since the late 19th century and the early 20th century, shaking tables have been used to separate gold, tin, tungsten and other minerals, and with the advancement of technology, it has been expanded to the processing of more types of ores. Shaking table beneficiation is a process based on the principle of gravity sorting. Through the density difference of mineral particles, useful minerals and impurities in the minerals are separated by vibration and stratification on the shaking table. At present, this technology still occupies an important position in modern mining and is widely used in the sorting of metal mines, heavy ores, lithium ores, rare earth ores, etc. In the shaking table beneficiation, the ore belt is fanned out along the oblique line from the feed end to the concentrate end. When the slurry passes through the bed surface, mineral particles of different densities are subjected to different effects of gravity and flushing water flow to form multi-layered zones, and finally the separation of minerals is achieved.

[0003] However, the existing intelligent ore receiving device for shaking table still has many shortcomings when sorting multiple products. First, after the spiral flow 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 generally only receives a single concentrate, lacks a solution 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 receiving plate of the current device is not adjustable, and it cannot be dynamically adjusted according to the change of the width of the ore belt, thereby affecting the effective collection and separation of minerals. The control line control is adopted in the prior art, 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 receiving 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.

[0018] 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 to provide a full understanding of the embodiments of the present application.

[0019] like Figure 1-6As shown, this embodiment discloses a multi-product intelligent ore receiving system of a beneficiation shaking table, including a shaking table 3 and an intelligent ore receiving device. The shaking table 3 is provided with a secondary concentrate chute 1 and a tailings chute 2, which are respectively used to receive and separate the secondary concentrate and tailings in the ore belt. The shaking table 3 uses the gravity difference to stratify the mineral particles of different densities through the set angle and vibration frequency, wherein the secondary concentrate flows into the secondary concentrate chute 1, and the tailings flow into the tailings chute 2, thereby achieving a preliminary separation effect. The intelligent ore receiving device includes a tailings conveying trough 4, a receiving plate 5, a concentrate conveying trough 6, a support frame 7, an intelligent ore receiving device box 8, a camera 9 and a camera bracket 10. The tailings conveying trough 4 is used to collect tailings and discharge them to the tailings chute 2, and the concentrate conveying 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 installed on one side of the tailings chute 2, and the other end is installed in the secondary concentrate chute 1. The support frame 7 provides stable support so that the intelligent ore receiving device can be stably installed to avoid position displacement of the ore receiving device 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 is convenient for 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 concentrates, and improving the efficiency of receiving ore. The receiving plate 5 includes a concentrate receiving plate 11, a receiving plate support frame 12, a calibration pipe 13 and a secondary concentrate receiving plate. The concentrate receiving plate 11 is fixed on the receiving plate support frame 12, and is used to collect a fixed width of the concentrate belt, and the secondary concentrate receiving plate is installed on the side of the concentrate receiving plate 11, so as to maintain a relatively independent space when receiving the concentrate and the secondary concentrate to prevent mineral mixing. The calibration tube 13 is used to calibrate the position of the receiving tray 5 and the width of the ore belt to ensure that the concentrate and sub-concentrate can be accurately collected in their respective receiving trays. The intelligent receiving device box 8 is installed above the support frame 7. The camera bracket 10 is located on the upper part of the intelligent receiving device box 8 and is used to install the camera 9. The camera 9 collects the distribution image of the ore belt on the shaking table 3 and transmits the image to the control device for analysis, so as to adjust the position and width of the receiving tray 5 in real time, thereby improving the sorting accuracy and mineral recovery rate.

[0020] 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 plate includes a motor 14, a water retaining plate 15, a camera fixing member 16, a coupling 17, a movable plate 18, a fixed block 19 and a bearing 20. The bearing 20 is mounted on the receiving plate 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 plate to adapt to the requirements of different ore belt widths and improve the accuracy and efficiency of mineral collection.

[0021] like Figure 4 As shown, further, the intelligent ore receiving device box 8 includes an 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, and the upper cover plate 26 and the lower cover plate 22 are installed on the ore receiving box frame 23 by screws to form a closed space for protecting the internal slide module 24 and the embedded development board 25 from the external environment. One end of the connecting block 27 is connected to the ore receiving plate 5, and the other end is fixed to the slide module 24 by screws, so that the slide module 24 can drive the ore receiving plate 5 to move along the slide rail. The movement of the slide module 24 makes the position of the ore receiving plate 5 adjustable to adapt to the position of different ore belts. The drag chain slot 29 is fixed on the ore receiving box frame 23, one end of the drag chain 28 is fixed on the connecting block 27 by screws, 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, avoiding the connection cable from being pulled or damaged during movement, and ensuring the stable operation of the cable. The embedded development board 25 is fixed on one side of the ore receiving box frame 23, as the core component of the control device, for receiving and processing image information from the camera 9, and controlling the operation of components such as the motor 14 and the slide module 24, to realize intelligent ore receiving control.

[0022] Furthermore, the support frame 7 is provided with threaded holes, and the support frame 7 can be fixed by screws. The design of threaded holes and screw connection makes the support frame 7 have high stability during installation, and can withstand the vibration and load during equipment operation, so as to avoid the loosening of the bracket 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, and the ore receiving box fixing angle steel 21 is fixed to the side wall of the secondary concentrate chute 1 of the shaking table 3 by screws to ensure the stable installation position of the intelligent ore receiving device box 8.

[0023] like Figure 6 As shown, the multi-product intelligent ore receiving system of the ore dressing shaking table also includes a transmission box 30 and a concentrate collection pipe 35. The transmission box 30 is used for power transmission and control, supports the movement and adjustment of the ore receiving plate 5 and other key components, and enables the entire system to 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 collect the concentrates from different sources into the same channel, which is convenient for subsequent unified processing or further concentrate sorting. In one embodiment, the shaking table 3 includes 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 large 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.

[0024] like Figure 7-8 As shown, in this embodiment, the multi-product intelligent ore receiving system of the ore dressing shaking table 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 concentrates, sub-concentrates 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, take real-time photos of the distribution of the ore belt on the shaking table 3, and provide these 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 wirelessly. After processing the image data, the cloud server outputs the recognition results, including the location, width and distribution boundaries of various minerals of the ore belt.

[0025] The embedded development board 25 receives the recognition results of the cloud server, generates control instructions based on these data, and sends the 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 specified ore belt position, so that the ore receiving plate can accurately align with the concentrate or sub-concentrate area on the ore belt. This control process realizes the automatic adjustment of the ore receiving plate, improves the accuracy and efficiency of mineral collection, and reduces manual intervention. Through wireless data transmission and cloud processing, the system not only improves the flexibility of control, but also reduces the number of cables of the ore receiving device, simplifying the construction and maintenance of the system.

[0026] like Fig. 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: S1, image acquisition: the distribution image of the ore belt is acquired through the camera, and the image data is transmitted to the embedded development board; 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; S3, ore belt identification and calculation: The cloud server receives and parses JSON data, identifies the boundary points of the ore belts, including the boundary point s1 between the concentrate belt and the secondary static belt, the boundary point s2 between the secondary static belt and the tailings belt, and the width s2-s1 of the secondary static belt; calculates the lateral movement distance of each receiving plate and the rotation angle of the movable plate of the secondary static plate according to the identification results; 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 network site; the embedded development board decodes the data and generates corresponding control instructions; 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 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 static belt. The rotating motor of the movable plate adjusts the width of the secondary static belt to the width of the secondary static belt s2-s1; S6, mineral separation: The concentrate receiving plate collects the concentrate and introduces it into the concentrate conveying trough, and then collects it into the concentrate collecting pipe; the secondary concentrate receiving plate 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 trough and are discharged along the tailings chute, realizing the separation of the three products of concentrate, secondary concentrate and tailings.

[0027] 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.

[0028] In this embodiment, the multi-product intelligent ore connection method of the ore dressing shaking table solves the problem that the traditional intelligent ore connection device relies on a large number of control lines, resulting in a large number of cables, complex construction, and a large maintenance workload through the intelligent collaboration of 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 by wireless transmission, and the accurate identification and position analysis of the ore belt is achieved with the help of the cloud image recognition algorithm, and then the control instructions are wirelessly transmitted back to the embedded development board to accurately adjust the position and width of the ore receiving plate. This method does not need to 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.

[0029] In summary, the present invention discloses a multi-product intelligent ore receiving system and method for a mineral processing shaking table. A concentrate receiving plate and a secondary concentrate receiving plate are provided to collect the concentrate and the secondary concentrate respectively. The concentrate is further collected in a concentrate collecting pipe, while the secondary concentrate enters a secondary concentrate chute, and the tailings are discharged through a tailings conveyor trough, thereby realizing the separation of the three products of concentrate, secondary concentrate and tailings. The secondary concentrate receiving plate is equipped with a movable plate controlled by a motor, 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, thereby avoiding the limitations of traditional control lines and reducing the complexity of construction and maintenance. The invention is suitable for digital mining environments, and provides an efficient and flexible mineral sorting solution, which greatly improves the automation level and mineral processing efficiency of the system, and provides strong support for the construction of intelligent mines.
