Description

Technical Field

[0001] This utility model relates to the field of color sorters, and in particular to a high-efficiency multi-stage ore track color sorter. Background Technology

[0002] A tracked color sorter, as the name suggests, is an advanced piece of equipment that uses a tracked conveyor system combined with color recognition technology to sort materials. It is widely used in the sorting processes of industries such as grain, ore, and plastics to improve product quality and production efficiency.

[0003] The ore materials to be sorted are usually quite dry, and a large amount of dust is easily generated during the conveying and vibration process. This dust can easily contaminate the optical lens and lighting system of the color sorter, which may affect the recognition accuracy, or even cause mis-sorting or missed sorting, requiring frequent shutdowns for cleaning, and affecting the continuous operation efficiency and stability of the equipment.

[0004] Chinese patent discloses a tracked ore color sorter, application number 202320370244.3. In order to solve the problem of dust affecting the photoelectric recognition effect in related technologies, the above patent has a dust removal port reserved on the sorting mechanism. The dust raised after the material is thrown out by the first or second conveyor belt can be absorbed through the dust removal port. At the same time, a dust removal component is also set on the sorting mechanism to clean the dust of the first and second recognition modules. The dust removal scraper is connected to the sorting mechanism through the support plate and the telescopic component and abuts against the sorting mechanism. During use, the telescopic component can drive the scraper to move at regular intervals to scrape off the floating dust on the sorting mechanism. The scraped dust falls down and is absorbed through the dust removal port.

[0005] However, when the aforementioned patented design uses a moving scraper to clean the dust from the surface of the sorting mechanism, the frequent friction between the scraper and the protective cover of the optical components can easily cause scratches on the mirror surface and may also obstruct the recognition of the first and second recognition modules, affecting recognition accuracy and even causing mis-selection or missed selection. Furthermore, using a cleaning method where one recognition module stops operating for cleaning while the other continues sorting may lead to a decrease in sorting capacity, thus affecting recognition accuracy. Utility Model Content

[0006] This utility model provides a high-efficiency multi-stage ore track color sorter, which can solve the problems of damage caused by scraper cleaning of the sorting mechanism and potential obstruction of the sorting mechanism affecting the recognition accuracy in existing high-efficiency multi-stage ore track color sorters.

[0007] A high-efficiency multi-stage ore track color sorter includes two machine bodies and multiple cameras. A first conveyor belt and a second conveyor belt are provided between the machine bodies. The second conveyor belt is located below the first conveyor belt and partially overlaps with the first conveyor belt.

[0021] 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.

[0022] like Figures 1 to 6 As shown in the figure, the present invention provides a high-efficiency multi-stage ore track color sorter, including two machine bodies 1 and multiple cameras 11. A first conveyor belt 2 and a second conveyor belt 3 are provided between the machine bodies 1. The second conveyor belt 3 is located below the first conveyor belt 2 and partially overlaps with the first conveyor belt 2. A first dust suction component and a drying component are provided above the first conveyor belt 2. The first dust suction component and the drying component are respectively used to remove dust and dry the material on the first conveyor belt 2. The camera 11 is located at the end of the first conveyor belt 2 and the second conveyor belt 3. A second dust suction component is provided at the camera 11. The second dust suction component includes a protective shell 10 covering the outside of the camera 11. The protective shell 10 has an opening near the lens of the camera 11. The second dust suction component is used to suck up the dust at the opening of the protective shell 10.

[0023] When the ore material to be sorted is conveyed on the first conveyor belt 2, the first dust suction component can extract dust during the conveying process of the dry material, while the drying component dries the material with high moisture content by blowing hot air, ensuring that the material can be conveyed evenly and sparsely, laying the foundation for high-precision identification and sorting. Furthermore, a double-layer conveyor belt design is adopted, with the first conveyor belt 2 as the upper layer and the second conveyor belt 3 as the lower layer. The protruding part of the second conveyor belt 3 relative to the first conveyor belt 2 is used to receive the sorted impurities, realizing secondary conveying and sorting of the material.

[0024] The color sorter's cameras 11 are installed at the ends of the first conveyor belt 2 and the second conveyor belt 3, respectively, to capture images of materials in motion. A protective shell 10 is installed around the camera 11, and a second dust suction component can be used to suck up dust near the opening of the protective shell 10. By continuously keeping the lens area clean, the camera 11 can acquire clear images of the materials, thereby ensuring the color sorter's high recognition accuracy and stable sorting effect.

[0025] A tracked color sorter is a device that uses high-speed cameras and computer algorithms to sort materials. By combining different light sources with various high-speed image processing technologies, it separates defective products and foreign objects from raw materials, improving production efficiency. It mainly uses a hopper, vibrating feeder, and track to smoothly convey materials, while simultaneously using photoelectric technology to detect color differences on the material surface. When abnormally colored materials are detected, the equipment reacts quickly, rejecting the abnormal materials through an air jet valve, thus achieving automatic sorting. The tracked color sorter involved in this application is prior art, and will not be described in detail here.

[0026] In some specific implementation plans, such as Figure 1 , Figure 2 and Figure 6 As shown, the second dust collection assembly also includes a mounting plate 9 fixed to the inner wall of the body 1, a first dust removal branch pipe 13 fixed to the protective shell 10, and a second dust collection hood 12 located inside the protective shell 10 and near the opening. The second dust collection hoods 12 are distributed on both sides of the lens of the camera 11 and are used to suck up dust that may adhere to the lens. The protective shell 10 is fixed to the mounting plate 9, and one end of the first dust removal branch pipe 13 is connected to the first dust removal main pipe 14. The first dust collection assembly includes a second dust removal main pipe 21 and multiple first dust collection hoods 4 fixed above the first conveyor belt 2. The first dust collection hoods 4 are all connected to the second dust removal main pipe 21. A dust collection system 20 is provided on one side of the first conveyor belt 2, and the second dust removal main pipe 21 and the first dust removal main pipe 14 are all connected to the dust collection system 20.

[0027] When the ore material to be sorted is relatively dry, the dust collection system 20 (such as a pulse bag filter) sucks up the dust generated during the material conveying process through the second dust collection main pipe 21 and the first dust collection hood 4, effectively suppressing the dust dispersion generated during material conveying and improving the working environment. At the same time, the dust collection system 20 also sucks up the dust collected by the second dust collection hood 12 through the first dust collection main pipe 14, the first dust collection branch pipe 13, and the second dust collection hood 12, reducing the adhesion of dust to the lens of the camera 11, ensuring a clear field of view for the camera 11, and guaranteeing stable sorting and identification accuracy.

[0028] In some specific implementation plans, such as Figure 1 and Figure 3 As shown, the drying assembly includes multiple air supply branch pipes 5 fixed to the bottom of the first dust collection hood 4 and multiple air outlet pipes 7 fixed to the bottom of the corresponding air supply branch pipes 5. One end of the multiple air supply branch pipes 5 is connected to the air supply main pipe 6. A hot air blower 19 is provided on the other side of the first conveyor belt 2. The air supply main pipe 6 is connected to the hot air blower 19.

[0029] When the surface moisture of the ore material to be sorted is too high, the hot air blower 19 operates, delivering hot air into the air branch pipe 5 through the main air duct 6, and blowing hot air downwards through the outlet pipe 7, thereby drying the material. By performing online light drying of the material, the surface moisture of the material is reduced, thus reducing the problem of material adhesion causing poor feeding or even blockage.

[0030] In some specific implementation plans, such as Figure 4 and Figure 5 As shown, it also includes multiple high-speed spray valves 15, which are located at the ends of the first conveyor belt 2 and the second conveyor belt 3. The high-speed spray valves 15 are arranged horizontally in the longitudinal direction. The high-speed spray valves 15 located above the first conveyor belt 2 are arranged vertically opposite to the protruding part of the second conveyor belt 3. The camera 11 located below the first conveyor belt 2 is arranged vertically opposite to the first discharge hopper 16. The camera 11 is tilted towards the corresponding end of the first conveyor belt 2 or the second conveyor belt 3.

[0031] The high-speed spray valve 15 is used to spray airflow based on the recognition result of the camera 11 to remove impurities. A set of high-speed spray valves 15 located above the first conveyor belt 2 performs primary sorting, and a set of high-speed spray valves 15 located below the first conveyor belt 2 performs secondary sorting of the materials after primary sorting.

[0032] In some specific implementation plans, such as Figure 2 , Figure 4 and Figure 5 As shown, a second discharge hopper 18 is fixed on one of the machine bodies 1 and below the end of the first conveyor belt 2, for receiving qualified materials after the first sorting; a first discharge hopper 16 and a waste hopper 17 are fixed on the other machine body 1 and below the end of the second conveyor belt 3. The first discharge hopper 16 is located between the second conveyor belt 3 and the waste hopper 17. The first discharge hopper 16 is used to receive materials after the second sorting, while the waste hopper 17 is used to collect rejected unqualified materials.

[0033] In some specific implementation plans, such as Figure 3 As shown, each air outlet pipe 7 is fixed with a duckbill valve 8. The rubber duckbill valve 8 is used to seal the air outlet pipe 7 and seal the pipe opening when not supplying air to prevent dust backflow.

[0034] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: The ore material to be sorted is conveyed on the first conveyor belt 2. If the ore material to be sorted is relatively dry, the dust collection system 20 sucks up the dust during the material conveying process through the second dust removal main pipe 21 and the first dust collection hood 4, effectively suppressing the dust generated during the material conveying process and improving the working environment. If the surface humidity of the ore material to be sorted is too high, the hot air blower 19 is operated, and hot air is conveyed into the air branch pipe 5 through the air conveying main pipe 6. The hot air is blown downward through the air outlet pipe 7 to achieve the drying of the material.

[0035] After this pretreatment, the material is conveyed to the end of the first conveyor belt 2 in a uniform and sparse state and falls. The high-speed camera 11 located here captures images, and the image signals are transmitted to the control system for identification. The control system then controls the corresponding high-speed spray valve 15 to open, blowing the identified impurities onto the second conveyor belt 3, thus completing the first-stage sorting.

[0036] The second conveyor belt 3 continues to transport materials, and at its end, the same image acquisition and spray sorting process is performed to achieve secondary sorting. The clean material from the secondary sorting falls into the first discharge hopper 16 for collection, while the unqualified waste material falls into the waste hopper 17 for centralized processing. Throughout the process, the dust collection system 20 also sucks up the dust collected by the second dust collection hood 12 through the first dust collection main pipe 14, the first dust collection branch pipe 13, and the second dust collection hood 12, reducing the adhesion of dust to the lens of the camera 11, ensuring a clear field of view for the camera 11, and thus ensuring that the equipment can operate stably for a long time and maintain high recognition accuracy under high dust conditions.

[0037] 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.
