Description

Technical Field

[0001] This utility model relates to an intelligent dust removal device for mineral processing, and in particular to an intelligent dust removal device for mineral processing applied in the field of dust removal equipment. Background Technology

[0002] Mineral beneficiation refers to the process of classifying different minerals and enriching them with target minerals from the ore extracted from the mine through a series of physical or chemical methods.

[0003] Chinese patent CN221875338U discloses a mining belt conveyor device, comprising: a conveyor frame; a conveyor belt fitted on the conveyor frame; protective strips on both sides of the conveyor belt; baffles at corresponding positions of the protective strips; a groove at the end of the baffle near the ground; the groove and the protective strips being slidably connected; and several rollers on the inner walls of both sides of the groove; the rollers being evenly distributed along the direction of the groove; the conveyor belt moves smoothly in the groove of the baffle using the protective strips on both sides, achieving a seamless connection between the conveyor belt and the baffle, effectively blocking crushed stone and ensuring the safe operation of the equipment; it also avoids friction between the baffle and the conveyor belt, and the rollers convert sliding into rolling, reducing wear on the protective strips on the conveyor belt, extending the service life of the conveyor belt, and reducing maintenance costs.

[0004] In traditional mining, the stockpiling process after ore beneficiation is mostly done in the open or with simple enclosures, and there is a lack of dust control measures during the stockpiling process. The impact of the ore on the already stockpiled part will continuously arouse a large amount of dust. Furthermore, due to the lack of real-time monitoring and control of dust diffusion, the dust will spread more freely, causing material loss and deteriorating the surrounding environment. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that the stockpiling process after mineral processing in traditional mines is mostly open-air stockpiling or simple enclosure, and there is a lack of dust control measures during the stockpiling process. The impact of the ore on the already stockpiled part will continuously arouse a large amount of dust. Furthermore, due to the lack of real-time monitoring and control of dust diffusion, the dust will spread more wantonly, causing both material loss and deterioration of the surrounding environment.

[0006] To address the aforementioned problems, this utility model provides an intelligent dust removal device for mining and beneficiation, comprising an electric conveyor belt, a conveyor cylinder installed at the lower end of the electric conveyor belt, an electric tensioning corrugated pipe at the lower end of the conveyor cylinder, a discharge cylinder fixedly connected to the lower end of the electric tensioning corrugated pipe, an upper frame plate fitted to the outer side of the discharge cylinder, a dust cover fixedly connected to the lower end of the upper frame plate, a lower frame plate fixedly connected to the lower end of the dust cover, multiple movable inner rings provided at the inner end of the upper frame plate, vertical slide rails symmetrically fixedly connected to the left and right sides of the lower end of the upper frame plate, a sliding strip slidably connected to the end of the vertical slide rail near the flexible enclosure, a spring provided at the lower end of the sliding strip, the spring being connected to the lower inner wall of the vertical slide rail, a dust suction port connected to the end of the sliding strip near the flexible enclosure, obliquely fitted pressure plates symmetrically arranged on the left and right sides of the connection between the discharge cylinder and the flexible enclosure, a dust monitoring sensor fixedly connected to the upper end of the dust suction port, and a control terminal externally connected to the dust monitoring sensor.

[0007] In the aforementioned intelligent mining beneficiation dust removal equipment, after beneficiation, the ore is precisely delivered to the unloading point via an electric conveyor belt. During the transition, the conveyor cylinder works in conjunction with the electric tensioning corrugated pipe to shield and guide the ore to fall in the drop zone due to the height difference, thereby curbing dust and reducing dust removal pressure. Furthermore, during the stacking process, the upper frame plate and dust cover on the outside of the drop cylinder enclose the ore accumulation area, which, together with the dust collection device, effectively prevents dust diffusion.

[0008] As a further improvement of this application, the multiple movable inner rings are arranged in equal-distance, decreasing-size configurations, and the material discharge cylinder penetrates both inside and outside the innermost movable inner ring.

[0009] As a further improvement of this application, the material discharge cylinder and the innermost movable inner ring are installed together, and the lower end of the material discharge cylinder is provided with multiple flexible surrounding plates.

[0010] As another improvement of this application, multiple flexible panels are arranged in a ring at equal intervals, and openings are provided on the outer side of the flexible panels.

[0011] As a further improvement to this application, the inclined adapter lower pressure plate abuts against the upper end of the sliding bar, and the upper end of the conveying cylinder is provided with a dustproof arc-shaped cover.

[0012] As a further improvement to this application, the left and right ends of the electric conveyor belt are symmetrically and fixedly connected with side baffles, and a dustproof arc-shaped cover is installed above the two side baffles.

[0013] As a further improvement to this application, a dust suction pipe is fixedly connected to the rear end of the conveying cylinder, and the dust suction pipe and the two dust suction ports are all connected to a pump through pipes.

[0014] In summary, in this solution, the ore after beneficiation is precisely transported to the designated unloading point via an electric conveyor belt. During the transition, the conveyor cylinder works in conjunction with an electric tensioning corrugated pipe to effectively shield and precisely guide the ore in the drop zone due to the height difference, thus curbing dust generation and reducing the pressure on subsequent dust removal. Before entering the storage stage, the upper frame plate and lower dust cover on the outside of the discharge cylinder can enclose the ore accumulation area to prevent dust diffusion. The multiple movable inner rings on the inner side of the upper frame plate change shape as the discharge cylinder rises. The inclined adapter plate on the outside of the discharge cylinder drives the dust suction port to slide vertically. The rails automatically rise according to the material stacking height, allowing the dust suction port to adapt to the stacking range and promptly extract dust. The sliding strip stretches downward along the vertical slide rail from its initial compressed state as the material is pushed forward, enhancing dust prevention. The dust monitoring sensor equipped with the dust suction port detects dust data inside the upper frame plate after the material stacking is completed. Once the dust level falls back to a safe range, the drive mechanism controls the dust removal mechanism to stop and reset, ensuring dust removal effectiveness and pass rate. In addition, the openings on the outer side of the flexible frame plate reduce the friction resistance between it and the ore, allowing for smoother contact and displacement, reducing the possibility of dust generation.

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figure 1-6 This invention discloses an intelligent dust removal device for mineral processing, comprising an electric conveyor belt 1, a conveyor cylinder 4 installed at the lower end of the electric conveyor belt 1, an electric tensioning corrugated pipe 7 installed at the lower end of the conveyor cylinder 4, a discharge cylinder 8 fixedly connected to the lower end of the electric tensioning corrugated pipe 7, an upper frame plate 5 fitted to the outer side of the discharge cylinder 8, a dust cover 11 fixedly connected to the lower end of the upper frame plate 5, a lower frame plate 12 fixedly connected to the lower end of the dust cover 11, a plurality of movable inner rings 6 provided at the inner end of the upper frame plate 5, and the lower left and right sides of the upper frame plate 5... A vertical slide rail 13 is symmetrically fixedly connected. A sliding strip 14 is slidably connected to one end of the vertical slide rail 13 near the flexible enclosure 9. A spring 16 is provided at the lower end of the sliding strip 14. The spring 16 is connected to the lower inner wall of the vertical slide rail 13. A dust suction port 15 is connected to one end of the sliding strip 14 near the flexible enclosure 9. Inclined adapter lower pressure plates 18 are symmetrically arranged on the left and right sides of the connection between the discharge cylinder 8 and the flexible enclosure 9. A dust monitoring sensor 17 is fixedly connected to the upper end of the dust suction port 15. A control terminal is externally connected to the dust monitoring sensor 17.

[0027] Figure 1-6 Multiple movable inner rings 6 are arranged at equal intervals and decreasing in size. The material discharge cylinder 8 passes through the innermost movable inner ring 6. The material discharge cylinder 8 and the innermost movable inner ring 6 are installed together. Multiple flexible surrounding plates 9 are provided at the lower end of the material discharge cylinder 8. The multiple flexible surrounding plates 9 are arranged in a ring at equal intervals. Opening holes 10 are provided on the outer side of the flexible surrounding plates 9. The inclined fitting lower pressure plate 18 and the upper end of the sliding strip 14 abut against each other.

[0028] Figure 1-6The diagram illustrates that after mineral processing, the ore is transported precisely to a designated unloading point via an electric conveyor belt 1, following a pre-set path. As the ore is conveyed on the electric conveyor belt 1 and transitions to subsequent stages, the conveyor cylinder 4 and the electric tensioning corrugated pipe 7 work together. This structural combination effectively shields and precisely guides the falling area caused by the height difference of the ore, thus curbing dust generation during the ore's descent and significantly reducing dust risk, easing the pressure on subsequent dust removal operations. When the ore completes the mineral processing and enters the stockpiling and storage stage, the outer side of the discharge cylinder 8 closes... The system is equipped with an upper frame plate 5, and a dust cover 11 tightly connected below the upper frame plate 5. This effectively encloses the overall space occupied by the ore pile, preventing dust from spreading freely into the surrounding environment during the pile-up process. Simultaneously, multiple movable inner rings 6, arranged at equal intervals on the inner side of the upper frame plate 5, change position synchronously as the material discharge cylinder 8 gradually rises during the pile-up process. During this process, the inclined, adaptable downward pressure plate 18 on the outer side of the material discharge cylinder 8 closely follows this upward movement, thereby driving the connected dust suction port 15 to move within the path defined by the vertical slide rail 13, according to the actual pile height of the material. With its upward-adapting design, the suction port 15 maintains a high degree of alignment with the material stacking height, ensuring timely and efficient extraction of dust generated during the stacking process. The sliding strip 14, connected to the suction port 15, is initially compressed. As the stacking operation continues, it gradually stretches under the guidance of the vertical slide rail 13, further enhancing the blocking of dust diffusion paths and improving the overall dust prevention effect. The suction port 15 is also equipped with a dust monitoring sensor 17. After the stacking operation is completed, the dust monitoring sensor 17 immediately initiates a precise detection process for dust data within the upper frame plate 5. Only when dust is detected in this area will the sensor detect the dust. When the dust data in the material area stabilizes and falls back to the pre-set safety index range, the dust removal mechanism can be stopped by the drive mechanism, and the relevant components can be moved to the initial standby position. This intelligent control system ensures the stability and reliability of the dust removal effect and effectively improves the qualification rate of dust removal operations. In addition, as a component that comes into direct contact with the ore, the openings 10 on the outer side of the flexible sheet 9 can effectively reduce the frictional resistance between the flexible sheet 9 and the ore during the falling and accumulation of the ore, making the flexible sheet 9 fit and move more smoothly with the ore, further reducing the possibility of dust generation.

[0029] Second implementation method:

[0030] Figure 2 , Figure 7This invention illustrates an intelligent dust removal device for mineral processing. A dustproof arc-shaped cover 3 is installed at the upper end of the conveyor cylinder 4. Side baffles 2 are symmetrically fixed to both ends of the electric conveyor belt 1. The dustproof arc-shaped cover 3 is positioned above the two side baffles 2. A dust suction pipe 19 is fixedly connected to the rear end of the conveyor cylinder 4. The dust suction pipe 19 and two dust suction ports 15 are all connected to pumps via pipes. At the starting point where the ore is output from the electric conveyor belt 1, the dustproof arc-shaped cover 3 is installed at the connection between the electric conveyor belt 1 and the conveyor cylinder 4. The dustproof arc-shaped cover 3 can initially contain the dust generated by the ore falling from a height. Combined with the dust suction pipe 19 at the rear of the conveyor cylinder 4, the two work together to suction and treat the dust generated at the beginning of the ore transport process, ensuring that the ore has a complete dust removal mechanism from both the top and bottom during the entire conveying and stockpiling process, thus comprehensively improving the dust removal efficiency in the mineral processing process.

[0031] In light of current practical needs, the above-described embodiments adopted in this application are not limited to this scope of protection. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
