Description

Technical Field

[0001] This utility model relates to the field of high-speed sorting equipment technology, specifically a multi-channel tracked high-speed sorting equipment. Background Technology

[0002] Ore sorting equipment is a key piece of equipment in the mining and resource recycling industries. It is used to efficiently separate valuable target minerals from waste rock or impurities based on the surface color, luster, texture, internal chemical composition, or physical properties of ore particles.

[0003] Currently, most mainstream high-speed ore sorting equipment in the industry adopts a pneumatic sorting structure based on optical sensing. Its structure typically includes: a feeding system comprising a vibrating feeder and a distribution hopper for evenly spreading the material; a high-speed track for smoothly conveying the material through the detection area; an optical detection system including a high-definition CCD camera, a near-infrared sensor, and a dedicated light source for acquiring characteristic information of each particle; an information processing system for real-time image processing and sorting decisions; and an array of high-pressure spray valves for ejecting compressed air according to instructions to blow identified impurity particles away from the main material flow, thereby achieving sorting.

[0004] Although the aforementioned pneumatic sorting structures are widely used, they have several technical shortcomings: First, their sorting capacity heavily relies on the airflow impact force of the spray valve. For ore blocks with high specific gravity and large size, the impact force is often insufficient to effectively remove them, resulting in incomplete sorting. Second, for difficult-to-sort impurities that are flat, flaky, or extremely irregular in shape, the air-blowing method is prone to misjudgment, failing to blow them away or blowing them off course, which seriously affects the final sorting purity.

[0005] Therefore, we propose a multi-channel tracked high-speed sorting device to solve the problems mentioned above. Utility Model Content

[0006] This utility model provides a multi-channel tracked high-speed sorting device, which can solve the problem that the existing pneumatic sorting structure relies too much on the airflow impact force of the spray valve. For large-density and large-size ore blocks, the impact force is often insufficient to effectively remove them, resulting in incomplete sorting.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A multi-channel tracked high-speed sorting device includes a sorting table, characterized in that: a hopper is fixedly installed at one end of the upper part of the sorting table, a feeding partition plate is installed at the bottom of the hopper, a first conveyor track is installed on the upper part of the sorting table, a horizontal partition plate is installed on the upper part of the first conveyor track, the horizontal partition plate divides the first conveyor track into multiple conveying channels, a pneumatic sorting mechanism is installed below the end of the conveying channel away from the hopper, the pneumatic sorting mechanism is used for sorting small and medium-sized ores, and a mechanical sorting mechanism is provided below the first conveyor track, the mechanical sorting mechanism is used for sorting medium and large-sized ores.

[0008] Preferably, the pneumatic sorting mechanism includes an array of spray valves and a first vision acquisition device. The array of spray valves consists of several linearly arrayed high-pressure spray valves. The high-pressure spray valves are fixedly installed at the end of the first conveyor belt away from the hopper, and the high-pressure spray valves are connected to high-pressure air pipes.

[0009] Preferably, the first vision acquisition device is installed at the end of the first conveyor belt away from the hopper, and the first vision acquisition device is installed at an angle and facing the array-type spray valve.

[0010] Preferably, the first vision acquisition device includes a mounting plate, on which a high-definition color CCD camera array and an industrial computer are integrated. Each conveying channel is equipped with a high-definition color CCD camera, which is used to identify color differences in materials and spectral differences in the internal chemical components of materials.

[0011] Preferably, a first separation track is provided in front of the array-type spray valve, and the first separation track is installed inside the sorting table.

[0012] Preferably, the mechanical sorting mechanism includes a support base plate, with multiple sets of channel partitions fixedly installed above the support plate. Each set of channel partitions has two channels, and independent conveyor belts are installed below the two channel partitions in the same set.

[0013] Preferably, a separation channel is provided between the two sets of channel partitions, and a guide plate is fixedly connected between the two sets of channel partitions. The guide plate is a V-shaped plate with an opening facing downwards.

[0014] Preferably, a second separation track is provided below the multiple sets of separation channels, and the end of the independent conveyor track away from the hopper protrudes from the end of the second separation track for ore sorting and separation.

[0015] Preferably, a second vision acquisition device and an active separation component are provided in the middle of the upper part of the independent conveyor belt. The active separation component and the second vision acquisition device work together to sort larger ore particles.

[0016] Preferably, the active separation component includes a miniature electric actuator, which is fixedly installed on a side channel partition of the same group. A push plate is fixedly installed on the telescopic end of the miniature electric actuator. A separation port is opened at a corresponding position on the side channel partition of the same group. A reset baffle is rotatably installed on the separation port. A reset spring is installed between the reset baffle and the upper edge of the separation port.

[0017] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model equipment uses horizontal partitions to physically divide the first conveyor belt into multiple independent conveying channels, and works in conjunction with the discharge partitions in the hopper to achieve uniform material distribution, significantly improving processing efficiency and sorting accuracy. A pneumatic sorting mechanism composed of arrayed high-pressure spray valves accurately removes small and medium-sized particle impurities. Simultaneously, a mechanical sorting mechanism located below the conveyor belt is used to specifically handle high-density ores that are difficult to move pneumatically and easily bouncing flaky ores. The mechanical sorting mechanism employs a micro-electric pusher-driven active separation component combined with a reset baffle structure to achieve rapid and accurate physical removal. A first vision acquisition device and a second vision acquisition device perform initial and re-inspection of the materials, respectively. Multi-dimensional optical feature analysis ensures the accuracy of identification. The design of the first and second separation tracks effectively prevents secondary contamination during the sorting process. Ultimately, it achieves high-speed, high-efficiency, and high-purity sorting of ores with various characteristics. This mechanical sorting mechanism is located below the first conveyor track and serves as a powerful supplement to pneumatic sorting. It performs secondary sorting of the ores, solving the problem that traditional pure pneumatic equipment cannot effectively remove ores with high specific gravity and large size, and that large pieces of ore cannot be blown away, thus ensuring the thoroughness of the sorting.

[0020] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0021] Example 1: Please see Figure 1-4 This utility model provides a technical solution: A multi-channel tracked high-speed sorting device includes a sorting table 1, a hopper 2 fixedly installed at one end of the upper part of the sorting table 1, a feeding partition plate 3 installed at the bottom inside the hopper 2, a first conveyor track 5 installed on the upper part of the sorting table 1, a horizontal partition plate 4 installed on the upper part of the first conveyor track 5, the horizontal partition plate 4 dividing the first conveyor track 5 into multiple conveying channels, a pneumatic sorting mechanism installed below the end of the conveying channel away from the hopper 2, the pneumatic sorting mechanism is used for sorting small and medium ore, and a mechanical sorting mechanism is set below the first conveyor track 5, the mechanical sorting mechanism is used for sorting medium and large ore.

[0022] In the above scheme, the mixed ore first enters the feed hopper 2, where it is initially distributed by the internal feed divider 3, and then conveyed to the first conveyor belt 5. The horizontal divider 4 above the belt physically divides the belt surface into multiple independent conveying channels, ensuring that the material is conveyed in parallel and uniformly, which is beneficial for subsequent efficient sorting. When the ore reaches the end of the conveyor, the optical detection system performs high-speed scanning and identification of the material in each channel. The information processing system, based on a preset algorithm, determines whether the particles are "good," "small to medium-sized impurities," or "large or difficult-to-sort impurities." For small or medium-sized impurities identified by the system, an instruction is issued to the pneumatic sorting mechanism, which consists of… The system consists of an array of high-pressure spray valves that precisely spray high-speed airflow the moment impurity particles detach from the conveyor belt and begin to fall, blowing them into the waste collection device located below. For heavy ores that are difficult to move pneumatically or for easily bouncing flaky ores, a mechanical sorting mechanism is used for sorting. This mechanical sorting mechanism is located below the first conveyor belt 5 and serves as a powerful supplement to pneumatic sorting, performing secondary sorting of the ores. This solves the problem that traditional pure pneumatic equipment cannot effectively remove heavy ores and large pieces of ores, and that large pieces of ores cannot be blown away, ensuring thorough sorting.

[0023] The pneumatic sorting mechanism includes an array of spray valves 7 and a first vision acquisition device 6. The array of spray valves 7 consists of several linearly arrayed high-pressure spray valves. The high-pressure spray valves are fixedly installed at the end of the first conveyor belt 5 away from the hopper 2, and the high-pressure spray valves are connected to high-pressure air pipes.

[0024] In the above scheme, several linear array high-pressure spray valves installed at the end of the first conveyor belt 5 are connected to the air source through high-pressure air pipes to form an execution unit, while the first vision acquisition device 6 is responsible for identification and positioning. When the ore material is transported to the end of the conveyor belt and is about to fall, the vision system of the first vision acquisition device 6 quickly captures the material characteristics and transmits them to the processing system. After the algorithm determines that it is a small or medium impurity, it immediately sends a command to the specific high-pressure spray valve at the corresponding position. The spray valve opens within milliseconds and sprays out highly concentrated compressed air, accurately hitting the target impurity and causing it to deviate from its original falling trajectory, thereby achieving efficient and selective pneumatic removal of small and medium particles.

[0025] The first vision acquisition device 6 is installed at the end of the first conveyor belt 5 away from the hopper 2. The first vision acquisition device 6 is installed at an angle and faces the array spray valve 7.

[0026] In the above scheme, the first vision acquisition device 6 is installed at an angle with its viewing angle facing the working area of ​​the array-type spray valve 7. It can accurately cover the falling trajectory of the ore material after it leaves the track. The angled view helps to reduce background interference from the track and can complete image acquisition in the early stage of material falling. This allows the system more time for image processing and spraying decision-making, thereby ensuring the time synchronization between the identification information and the spraying action. This effectively improves the accuracy of positioning the moving target and avoids spraying errors caused by image acquisition delay.

[0027] The first vision acquisition device 6 includes a mounting plate, on which a high-definition color CCD camera array and an industrial computer are integrated. Each conveying channel is equipped with a high-definition color CCD camera, which is used to identify color differences in materials and spectral differences in the internal chemical composition of materials.

[0028] In the above scheme, the first vision acquisition device 6 includes a high-definition color CCD camera array and an industrial computer integrated on the mounting plate; each independent conveying channel is equipped with a dedicated high-definition color CCD camera to achieve parallel detection; the color CCD camera is responsible for capturing rich surface color and texture information of the material, and is also configured to analyze specific spectral bands to detect differences in the internal chemical composition of the material; the industrial computer processes the large amount of image data transmitted by each color CCD camera in real time, performs high-speed calculation and comparison through the built-in intelligent algorithm model, instantly completes the attribute judgment of each particle, and sends the sorting instruction to the execution mechanism.

[0029] A first separation track 8 is provided in front of the array-type spray valve 7, and the first separation track 8 is installed inside the sorting table 1.

[0030] In the above scheme, a first separation track 8 is provided in front of the array-type spray valve 7; its function is to receive and transport away the impurities that have been successfully removed; when the high-pressure spray valve blows small and medium-sized impurities away from the main falling track, these impurities will fall onto the first separation track 8 located below it; the track continues to operate, which can quickly transport the impurity particles to a special waste collection area, thereby avoiding the accumulation of blown-off impurities inside the equipment or the rebound splashing that may cause secondary pollution to the main material flow, ensuring the cleanliness of the sorting environment and the high purity of the finished product.

[0031] Example 2: Please see Figure 1-4 Furthermore, in conjunction with Embodiment 1, the mechanical sorting mechanism includes a support base plate 11, with multiple sets of channel partitions 12 fixedly installed above the support plate. Each set of channel partitions 12 has two channels, and independent conveyor belts 17 are installed below the two channel partitions 12 in the same set.

[0032] The supporting base plate 11 provides a stable foundation for the mechanical sorting mechanism. Its multiple sets of channel partitions 12 divide the space into several independent sorting units. The independent conveyor belts 17 set under each set of partitions are used to receive and continue to transport large pieces or difficult ores falling from the first conveyor belt 5 above. This allows the materials after primary pneumatic sorting to be physically isolated and transported secondary according to the channels, providing an orderly and non-interfering working environment for subsequent precise mechanical sorting of large particles of ore, ensuring the continuity and reliability of the sorting process.

[0033] A separation channel 18 is provided between the two sets of channel partitions 12, and a guide plate 13 is fixedly connected between the two sets of channel partitions 12. The guide plate 13 is a V-shaped plate with the opening facing downward.

[0034] In the above scheme, a separation channel 18 is formed between two adjacent sets of channel partitions 12, and a V-shaped guide plate 13 with an opening facing downward is fixedly connected to it. The function of the guide plate 13 is to guide and gather large pieces of ore falling from the independent conveyor belt 17, so that they fall into the corresponding separation channel 18. At the same time, the V-shaped structure can effectively prevent ore from getting stuck or splashing, thus optimizing the material flow direction.

[0035] A second separation track 19 is provided below multiple sets of separation channels 18. The end of the independent conveyor track 17 away from the hopper 2 protrudes from the end of the second separation track 19 and is used for ore sorting and separation.

[0036] In the above scheme, a second separation track 19 is set under multiple sets of separation channels 18 to uniformly receive and transport the waste generated by all mechanical sorting channels; the discharge end of each independent conveyor track 17 extends and protrudes from the end of the second separation track 19. This structure ensures that large pieces of ore that have been identified as waste falling from the independent tracks are efficiently transported to a unified waste collection point to separate the waste ore from the qualified ore.

[0037] The upper middle part of the independent conveyor belt 17 is equipped with a second vision acquisition device 10 and an active separation component. The active separation component and the second vision acquisition device 10 work together to sort larger ore particles.

[0038] A second vision acquisition device 10 and an active separation component are installed above the middle of the independent conveyor belt 17. The second vision acquisition device 10 and the active separation component work together to complete the final sorting of large pieces of ore. The second vision acquisition device 10 re-inspects and precisely locates the ore on the belt, identifies large impurities that still need to be removed, and transmits the signal to the active separation component. The active separation component then starts and performs precise physical removal, thereby realizing secondary fine sorting of large-scale ore, making up for the shortcomings of pneumatic sorting and ensuring the purity of the final product.

[0039] The active separation component includes a miniature electric actuator 14, which is fixedly installed on a side channel partition 12 of the same group. A push plate 15 is fixedly installed on the telescopic end of the miniature electric actuator 14. A separation port is opened at a corresponding position on the side channel partition 12 of the same group. A reset baffle 16 is rotatably installed on the separation port. A reset spring is installed between the reset baffle 16 and the upper edge of the separation port.

[0040] The active separation component is a miniature electric push rod 14, which is fixed to one side of the channel partition 12 and has a push plate 15 installed at its telescopic end. When the system command arrives, the miniature electric push rod 14 extends rapidly, driving the push plate 15 to push the identified large target impurities out of the independent conveyor belt 17 through the preset separation port. The reset baffle 16, which is hinged at the separation port, is pushed open when the push plate 15 is applied. After the impurities are discharged, the reset baffle 16 automatically returns to its original position and closes under the tension of the reset spring, ready for the next action. This design achieves fast, accurate and automated mechanical rejection, while avoiding material backflow and contamination after sorting.

[0041] The working principle of this multi-channel tracked high-speed sorting equipment is as follows: The mixed ore first enters the feeding hopper 2, where the feeding partition plate 3 initially distributes the material to ensure uniform dispersion. Subsequently, the material is conveyed to the first conveyor track 5, whose surface is physically divided into multiple independent conveying channels by horizontal partition plates 4, ensuring that the material is conveyed forward in parallel and uniformly, providing a foundation for subsequent sorting.

[0042] When the ore reaches the end of the first conveyor belt 5, the first vision acquisition device 6 performs high-speed scanning of the material on each channel. The camera captures the spectral characteristics of the material's surface color, texture, and internal chemical composition. The industrial computer processes the image data in real time and uses a preset algorithm to determine whether each particle is a "good product," a "small to medium impurity," or a "large or difficult impurity."

[0043] For the identified small and medium-sized particulate impurities, the system commands are transmitted to the array-type high-pressure spray valve. The spray valve precisely sprays a high-speed airflow the moment the impurity particles detach from the track and fall, blowing them onto the first separation track 8 located below. The first separation track 8 transports the removed impurities to the waste collection area to prevent secondary pollution.

[0044] For heavy, large-sized, or flat flaky ores that cannot be effectively removed by pneumatics, they naturally fall to the mechanical sorting mechanism below the first conveyor belt 5.

[0045] The mechanical sorting mechanism consists of multiple independent conveyor belts 17 and an active separation component. The second vision acquisition device 10 re-inspects the ore on the independent belts and accurately locates the impurities that need to be removed. After receiving the instruction, the active separation component drives the push plate 15 through the micro electric push rod 14 to push the target impurities out of the separation port. After the reset baffle 16 is activated, it automatically returns to its original position through the reset spring to prevent material backflow. The pushed-out waste falls into the second separation belt 19 below and is uniformly transported to the waste collection point.

[0046] High-quality ore continues to be conveyed along the independent conveyor belt 17 into the finished product collection device. All pneumatically and mechanically rejected waste is separated and transported to a designated area to ensure the high purity of the final product.

[0047] Multiple independent channels are formed by the horizontal partition plate 4, which improves sorting efficiency and accuracy and solves the problem that pure pneumatic equipment is not able to remove large-specific-gravity and large-size ores. The first vision acquisition device 6 and the second vision acquisition device 10 ensure full recognition coverage and reduce misjudgment.

[0048] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
