Description

Technical Field

[0001] This invention belongs to the technical field of mineral powder collection equipment, specifically relating to an environmentally friendly mineral powder collection device for use in phosphorus tailings. Background Technology

[0002] Phosphate tailings are solid waste generated during phosphate mining and processing. They contain certain amounts of minerals such as phosphorus, calcium, and magnesium, and have the potential for resource utilization. However, during the collection, transportation, and storage of phosphate tailings, the small, dry, and brittle nature of the ore particles easily generates large amounts of mineral dust. This dust not only wastes resources but also poses serious threats to the environment and human health. First, the dust disperses in the air, forming suspended particulate matter, leading to a decline in air quality and polluting the surrounding ecosystem, affecting plant growth and soil structure. Second, the dust may contain heavy metals and other harmful substances. These substances, once inhaled, can cause respiratory diseases (such as pneumoconiosis and asthma) and even long-term damage to the cardiovascular and immune systems. Furthermore, the accumulation of dust can pose an explosion risk, especially in enclosed or semi-enclosed working environments. When the dust mixes with air to a certain concentration, it may explode upon contact with an open flame or static spark, threatening the safety of workers. Therefore, the dust problem during phosphate tailings collection is not only an environmental issue but also a comprehensive technical challenge involving resource utilization, ecological protection, and safe production.

[0003] Currently, traditional mineral powder collection equipment has many shortcomings in phosphate tailings treatment. For example, common mechanical collection equipment such as belt conveyors and bucket elevators easily generate dust during operation and lack effective dust control measures. While some wet dust collection equipment can reduce dust diffusion, it suffers from high water consumption, severe equipment corrosion, and complex subsequent wastewater treatment. Furthermore, traditional dust removal technologies such as bag filters and electrostatic precipitators often face challenges such as equipment clogging, low efficiency, and high operating costs when dealing with phosphate tailings dust. Therefore, there is an urgent need for an environmentally friendly, on-site mineral powder collection device for phosphate tailings that can effectively treat mineral dust during the collection process and improve dust removal efficiency. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an environmentally friendly mineral powder collection device for use in phosphorus tailings, which can solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention discloses an environmentally friendly mineral powder collection device for use in phosphate tailings, comprising an annular conveyor belt and a drive device for driving the conveyor belt. The conveyor belt is used to transport mineral powder from one end to the other for collection. A plurality of through holes are arrayed on the surface of the conveyor belt, and a suction pipe is slidably disposed within each through hole. The suction pipe has suction holes on its surface, and its outer end extends from the through hole. Its inner end communicates with a suction chamber, and the negative pressure generated by the suction pipe removes dust from the surface of the mineral powder. The suction chamber is fixed to the inner side of the conveyor belt, and adjacent suction chambers are connected by pipes. At least one suction chamber is connected to a negative pressure suction device via an air inlet pipe. The drive device includes a driving roller, a driven roller, and a motor. The output end of the motor is connected to the driving roller. Top teeth are evenly distributed circumferentially on the outer sides of the driving and driven rollers. These top teeth engage with the inner side of the conveyor belt, and a groove is formed between adjacent top teeth to allow space for the suction chamber.

[0007] Furthermore, a central shaft is slidably mounted at the center of the suction pipe, and an anti-clogging component is hinged to the outside of the central shaft. The anti-clogging component extends out from the suction hole. A shaft end plate is fixedly connected to the inner end of the central shaft. A first elastic support device is connected between the shaft end plate and the suction pipe. An axial displacement drive device that drives the shaft end plate to move is provided on the inner side of the conveyor belt.

[0008] Furthermore, an end plate is fixed to the inner end of the suction pipe, and a second elastic support device is connected between the end plate and the conveyor belt.

[0009] Furthermore, the anti-clogging component includes a main scraper, a first pin, a secondary scraper, a second pin, and a torsion reset device. One end of the main scraper is hinged to the central shaft via the first pin, and the other end of the main scraper extends out from the through hole. One end of the secondary scraper is hinged to the middle of the main scraper via the second pin, and the other end of the secondary scraper extends out from the through hole. An angle is formed between the secondary scraper and the main scraper. A torsion reset device is provided between the main scraper and the secondary scraper.

[0010] Furthermore, the air intake chamber includes a conical chamber body, the upper end of which is fixedly connected to the conveyor belt, the lower end of which is sealed by a flexible membrane, and the shaft end plate is fixed to the inner surface of the flexible membrane.

[0011] Furthermore, the axial displacement driving device includes several transmission rollers arranged parallel to the conveying direction of the conveyor belt, a cam fixed on the surface of the transmission rollers, the several transmission rollers being connected by a transmission belt, the transmission rollers being rotatably mounted on a support, the support being fixedly connected to a column, and the cam being able to cooperate with the outer surface of the flexible membrane after rotation.

[0012] Furthermore, the transmission belt cooperates with both the driving roller and the driven roller, and two sets of top teeth are correspondingly provided on the same driving roller or driven roller. The two sets of top teeth are axially spaced to form a gap for the transmission belt to make way.

[0013] The beneficial effects of this invention are as follows:

[0014] This invention discloses an environmentally friendly mineral powder collection device for use in phosphorus tailings. The upper surface of the conveyor belt is used to transport mineral powder. By installing a dust suction pipe on the upper surface of the conveyor belt, the dust suction pipe can extend into the interior of the mineral powder, thereby collecting the mineral dust on the surface of the mineral powder, which can achieve a more effective collection effect.

[0015] In the device disclosed in this invention, by installing the suction chamber on the inner side of the conveyor belt, the overall structure is more compact and will not obstruct the collection of mineral powder. A tooth groove is formed between two adjacent top teeth to make way for the suction chamber, which effectively avoids the interference problem between the suction chamber and the drive equipment and ensures the stable operation of the device.

[0016] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0024] like Figures 1-5 As shown, this invention discloses an environmentally friendly mineral powder collection device for use in phosphate tailings. The mineral powder consists of large pieces of phosphate tailings that have fallen off the mine. It is collected after being transported by a conveyor belt for subsequent processing. Mineral dust is the dust adhering to the surface of the mineral powder. During the transport of the mineral powder on the conveyor belt, dust is easily generated. Existing technologies lack effective dust control measures, therefore, it is necessary to collect and treat the mineral powder to prevent dust generation. The collection device includes a ring-shaped conveyor belt 1 and a drive device for driving the conveyor belt 1. The drive device can be an existing roller, and the motor can drive the roller to rotate through a reducer. The friction between the roller and the conveyor belt 1 drives the conveyor belt 1 to move. In some other embodiments, the motor drives a chain, which meshes with a sprocket on the conveyor belt 1, driving the conveyor belt 1 to move.

[0025] In this invention, a plurality of through holes 2 are arrayed on the surface of the conveyor belt 1. A dust suction pipe 3 is slidably disposed within each through hole 2 along the normal direction of the conveyor belt 1. Dust suction holes 4 are formed on the surface of the dust suction pipe 3, and are evenly spaced on the outer surface of the dust suction pipe 3. The outer end of the dust suction pipe 3 extends from the through hole 2 and penetrates into the interior of the mineral powder and ore blocks. This allows for the collection of mineral dust from the surface of the mineral powder, achieving a more effective collection effect.

[0026] Furthermore, the inner end of the suction pipe 3 disclosed in this invention is connected to the suction chamber 5, which is fixed to the inner side of the conveyor belt 1. Adjacent suction chambers 5 are connected by pipes 6, and at least one suction chamber 5 is connected to a negative pressure suction device through an air inlet pipe 7. The air inlet pipe 7 is a flexible hose, which can accommodate the displacement of the suction chamber 5. This invention uses a single negative pressure suction device for unified conveying, which allows for convenient control.

[0027] Specifically, the driving device includes a driving roller 8, a driven roller 9, and a motor. The output end of the motor is connected to the driving roller 8. Top teeth 10 are evenly spaced along the circumference on the outer sides of both the driving roller 8 and the driven roller 9. These top teeth 10 engage with the inner side of the conveyor belt 1, and a groove 11 is formed between adjacent top teeth 10 to allow space for the suction chamber 5. The groove 11 provides clearance for the suction chamber 5, preventing interference. This design not only improves the stability of the transmission but also ensures that the conveyor belt 1 will not slip or deviate during operation. Through the coordinated operation of the above components, the motor drives the driving roller 8 to rotate, and the driving roller 8 drives the conveyor belt 1 to move through the meshing of the top teeth 10, thereby achieving continuous and smooth transmission of the circular conveyor belt 1.

[0028] This equipment is suitable for various scales and types of phosphorus tailings treatment scenarios, effectively coping with high dust concentration working environments, and possesses strong versatility and adaptability. The suction chamber 5 can be detachably connected to the conveyor belt 1, making the equipment's structural design easy to disassemble and clean. The modular design of the dust suction pipe 3 and the suction chamber 5 makes maintenance and replacement more convenient, reducing equipment maintenance costs and time.

[0029] In this embodiment, a central shaft 12 is slidably mounted at the center of the suction pipe 3. An anti-clogging component 13 is hinged to the outer side of the central shaft 12, extending from the suction hole 4. A shaft end plate 14 is fixedly connected to the inner end of the central shaft 12. A first elastic support device 15 connects the shaft end plate 14 and the suction pipe 3. An axial displacement drive device that drives the shaft end plate 14 to move is provided on the inner side of the conveyor belt 1. The combination of the central shaft 12 and the anti-clogging component 13 can dynamically adjust the position and angle of the anti-clogging component 13 when the suction pipe 3 is working, preventing dust from accumulating around the suction hole 4, thereby effectively avoiding clogging problems. In addition, the axial displacement drive device enables the central shaft 12 to achieve axial displacement during the operation of the conveyor belt 1, facilitating the unblocking of the suction hole 4.

[0030] In this embodiment, an end plate 16 is fixed to the inner end of the suction pipe 3, and a second elastic support device 17 is connected between the end plate 16 and the conveyor belt 1. This allows the suction pipe 3 to elastically reset when subjected to external force, ensuring the flexibility of the suction pipe 3 and extending the service life of the equipment. The second elastic support device 17 provides a buffering effect when the suction pipe 3 is subjected to external impact or vibration, preventing damage to the suction pipe 3 due to excessive force. At the same time, it enhances the uniformity and comprehensiveness of dust adsorption. This design not only improves dust collection efficiency but also reduces equipment maintenance frequency and lowers operating costs, making it particularly suitable for high-dust-concentration phosphorus tailings treatment environments. The stiffness of the second elastic support device 17 is greater than that of the first elastic support device 15. The axial displacement drive device first compresses the first elastic support device 15, causing the central shaft 12 to displace, and finally displaces the suction pipe 3.

[0031] In this embodiment, the anti-clogging component 13 includes a main scraper 18, a first pin 19, a secondary scraper 20, a second pin 21, and a torsion reset device 22. The torsion reset device 22 is a torsion spring. One end of the main scraper 18 is hinged to the central shaft 12 via the first pin 19, and the other end of the main scraper 18 extends out from the through hole 2. One end of the secondary scraper 20 is hinged to the middle of the main scraper 18 via the second pin 21, and the other end of the secondary scraper 20 extends out from the through hole 2. An angle is formed between the secondary scraper 20 and the main scraper 18. The torsion reset device 22 is provided between the main scraper 18 and the secondary scraper 20. The combined design of the main scraper 18, the first pin 19, the secondary scraper 20, the second pin 21, and the torsion reset device 22 further enhances the anti-clogging capability and cleaning effect of the equipment. The main scraper 18 is hinged to the central shaft 12 via the first pin 19, and its angle can be flexibly adjusted when the central shaft 12 moves, effectively cleaning the dust accumulation around the suction hole 4. The auxiliary scraper 20 is hinged to the main scraper 18 via a second pin 21, forming an angle with the main scraper 18. This design allows the scraper to cover a larger cleaning area, further improving the cleaning effect. The torsion reset device 22 enables the main scraper 18 and the auxiliary scraper 20 to automatically reset after completing the cleaning action, ensuring continuous operation of the equipment. This anti-clogging component 13 not only significantly reduces equipment clogging problems but also reduces the frequency of manual cleaning and maintenance costs, making it particularly suitable for high-dust-concentration phosphate tailings treatment scenarios.

[0032] In this embodiment, the air intake chamber 5 includes a conical chamber body 23. The upper end of the chamber body 23 is fixedly connected to the conveyor belt 1, and the lower end of the chamber body 23 is closed by a flexible membrane 24. The shaft end plate 14 is fixed to the inner surface of the flexible membrane 24 and can adapt to the displacement of the shaft end plate 14.

[0033] In this embodiment, the axial displacement drive device includes several drive rollers 25 arranged parallel to the conveying direction of the conveyor belt 1, and cams 26 fixed on the surface of the drive rollers 25. The drive rollers 25 are connected by a drive belt 27 to realize belt drive of the drive rollers 25. Belt drive is a mechanical transmission that uses a flexible belt tensioned on a pulley to transmit motion or power. Depending on the transmission principle, there are friction belt drives that rely on the friction between the belt and the pulley, and synchronous belt drives that rely on the meshing of the teeth on the belt and the pulley. Those skilled in the art should understand this. The drive rollers 25 are rotatably mounted on a bracket 28, and the bracket 28 is fixedly connected to a column 29. After rotation, the cams 26 can cooperate with the outer surface of the flexible membrane 24. Through the combined design of the drive rollers 25, cams 26, and drive belt 27, the axial displacement control of the suction pipe 3 is realized, significantly improving the automation level and operating efficiency of the equipment. The cams 26 on the surface of the drive rollers 25 can cooperate with the outer surface of the flexible membrane 24. The rotation of the cams 26 drives the suction pipe 3 to achieve axial displacement, ensuring that the suction holes 4 can cover a larger working range. The design of the drive belt 27 in conjunction with the driving roller 8 and driven roller 9 allows the axial displacement drive device to synchronize with the operation of the conveyor belt 1, further improving the coordination and stability of the equipment. This design not only simplifies the equipment structure but also reduces operating energy consumption, making it particularly suitable for large-scale phosphate tailings processing scenarios.

[0034] In this embodiment, the drive belt 27 cooperates with both the driving roller 8 and the driven roller 9. Two sets of top teeth 10 are correspondingly provided on the same driving roller 8 or driven roller 9, and the two sets of top teeth 10 are axially spaced to create a gap for the drive belt 27 to make way. This cooperative design of the drive belt 27 with the driving roller 8 and driven roller 9 further optimizes the transmission efficiency and space utilization of the equipment. By providing two sets of top teeth 10 on the same driving roller 8 or driven roller 9, and creating an axial gap for the drive belt 27 to make way, this design allows the drive belt 27 to operate synchronously with the conveyor belt 1, avoiding interference problems. At the same time, the arrangement of the drive belt 27 simplifies the equipment structure and reduces manufacturing costs and maintenance difficulty.

[0035] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
