Description

Technical Field

[0001] This utility model relates to the field of screening technology, specifically a vanadium ore vibrating screen. Background Technology

[0002] Vanadium, a high-melting-point metal, is light gray in appearance, possesses both ductility and high hardness, and is non-magnetic. It exhibits outstanding chemical stability, showing good resistance to hydrochloric acid and sulfuric acid, and its resistance to gas-salt-water corrosion is superior to most stainless steels. It is not easily oxidized in air and is only soluble in hydrofluoric acid, nitric acid, and aqua regia. Vanadium's natural habitat is vanadium ore; more than 70 vanadium-bearing minerals have been discovered, among which the main minerals with industrial mining value include vanadium-titanium magnetite, potash-vanadium-uranium ore, and petroleum-associated minerals. It is important to note that preparing high-purity vanadium is quite challenging. Under normal high-temperature environments, vanadium exhibits strong reactivity with oxygen, nitrogen, and carbon, readily undergoing chemical reactions. Therefore, in industrial applications, it is often used to prepare alloys to leverage its superior properties. However, in the industrial processing of vanadium ore, screening out particles with a size that meets the requirements of subsequent processes is a key preliminary step. Whether it is roasting, leaching, or purification, vanadium ore particles of a specific size are required as raw materials. If the particle size deviation is too large, it can easily affect the efficiency of subsequent reactions, reduce the purity of the product, or even cause blockages in the process. However, most conventional vibrating screens on the market have obvious limitations: their screening speed is mostly fixed and cannot be flexibly adjusted according to actual production needs. This fixed-speed design presents several inconveniences: Firstly, the fixed screening speed may lead to unstable screening results for different batches of vanadium ore. Secondly, when subsequent processes adjust the particle size requirements of vanadium ore, the fixed screening speed cannot adapt to the new particle size standards. Operators need to repeatedly screen or replace equipment to meet the requirements, which not only increases the workload and time costs but may also cause ore particle breakage due to repeated processing, affecting the utilization rate of raw materials. In addition, in large-scale production, if the capacity of the screening stage needs to be adjusted according to the overall production rhythm, the fixed-speed vibrating screen cannot be flexibly matched, thus restricting the efficiency of the entire vanadium ore processing production line.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please see Figures 1 to 5This utility model provides a technical solution: a vanadium ore vibrating screen, including a vibrating screen 1. The vibrating screen 1 adopts existing technology, and its core structure and working principle are well known to those skilled in the art, belonging to a mature technical solution in the industry. Therefore, its working principle will not be described in detail. The vibrating screen 1 is equipped with a screen plate 3 capable of adaptively adjusting its angle, and a first limiting slider 5 capable of rotating with the screen plate 3 is provided on the right side of the vibrating screen 1. A limiting plate 6 is fixedly connected to the right side of the first limiting slider 5. The limiting plate 6 is close to the first... One side of a limiting slider 5 is attached to the vibrating screen 1. The rear end of the limiting plate 6 is threaded with a limiting bolt 7 that can be inserted into the vibrating screen 1. The upper surface of the vibrating screen 1 is provided with an air suction pipe 16 that can extract air from the vibrating screen 1. The end of the air suction pipe 16 away from the vibrating screen 1 is connected to the air inlet of the cyclone dust collector. When the vibrating screen 1 is performing screening operations on vanadium ore, the cyclone dust collector can promptly suck in and collect the dust generated in the vibrating screen 1 through the air suction pipe 16, thereby effectively preventing dust particles from spreading into the air and causing pollution.

[0017] Please see Figures 2 to 5 The vibrating screen 1 has a feed inlet at the front end of its upper surface, a first discharge outlet at the bottom end, and a second discharge outlet at its rear end. The feed hopper 2 is fixedly connected to the front end of the upper surface of the vibrating screen 1, and the bottom end of the feed hopper 2 can completely cover the feed inlet. Therefore, the vanadium ore material to be screened can enter the vibrating screen 1 through the feed inlet and then be classified and screened by the screen plate 3: particles that meet the preset particle size requirements will be screened out through the screen holes of the screen plate 3 and discharged from the vibrating screen 1 through the first discharge outlet, while materials that do not meet the preset particle size requirements will be conveyed along the surface of the screen plate 3 and finally discharged from the vibrating screen 1 through the second discharge outlet.

[0018] Please see Figures 2 to 5 The middle of both sides of the screen plate 3 is fixedly connected to the first rotating shaft 10. The ends of the two first rotating shafts 10 away from the screen plate 3 are rotatably connected to the inner side of the vibrating screen 1. An adaptive adjustment component is provided at the front end of the lower surface of the screen plate 3. The adaptive adjustment component includes two second limiting sliders 15 slidably connected to the left and right sides of the vibrating screen 1, and an auxiliary connecting plate 11 is fixedly connected to the opposite ends of the two second limiting sliders 15. A plurality of second springs 13 are fixedly connected to the upper surface of the auxiliary connecting plate 11, and a plurality of first springs 12 are fixedly connected to the lower surface of the auxiliary connecting plate 11. The end of the second spring 13 away from the auxiliary connecting plate 11 is fixedly connected to the screen plate 3, and the end of the first spring 12 away from the auxiliary connecting plate 11 is fixedly connected to the inner wall of the vibrating screen 1. Therefore, when the vibrating screen 1 is working, the screen plate 3 performs screening operations on the incoming materials. Due to the natural differences in the weight of individual materials, when a large amount of material enters the vibrating screen 1, the front end of the screen plate 3 will be displaced downward due to the sudden increase in instantaneous load. According to the principle of force balance, the screen plate 3 will rotate adaptively around its first rotating shaft 10 pivot point, resulting in a reduction in the overall tilt angle. The reduction in tilt angle can slow down the flow speed of the material on the screen plate surface, prolong the contact time between the material and the screen surface, thereby reducing the screening speed. This adaptive adjustment mechanism can avoid insufficient screening due to excessive material and effectively ensure the stability of the screening effect. During the rotation of the screen plate 3, the first spring 12 and the second spring 13 will undergo elastic deformation and compression due to the force. Based on the characteristic of "elastic body storing potential energy when deformed under force" in elastic mechanics, the compression of the springs can buffer the instantaneous load impact at the front end of the screen plate 3, avoiding component wear caused by rigid contact. At the same time, the rotation of the screen plate 3 drives the auxiliary connecting plate 11 to move downward synchronously through the mechanical connection relationship. The displacement of the auxiliary connecting plate 11 drives the second limit slider 15 to move synchronously through rigid transmission, realizing the coordinated linkage of the actions of each component of the screening system, and ensuring that the overall structure remains stable during dynamic adjustment.

[0019] Please see Figures 2 to 5 The vibrating screen 1 has a second limiting groove 14 on the front of both the left and right sides. The ends of the two second limiting sliders 15 away from the auxiliary connecting plate 11 are slidably connected in the corresponding second limiting grooves 14. Therefore, when the auxiliary connecting plate 11 drives the second limiting sliders 15 to move up and down, the second limiting sliders 15 will slide adaptively along the trajectory of the second limiting grooves 14.

[0020] A first limiting slide 4 is provided in the middle of the right side of the vibrating screen 1. The first limiting slide 4 has an arc-shaped structure, and the center of the arc is concentric with the axis of the first rotating shaft 10. This ensures that the movement trajectory of the first limiting slide 4 always revolves around the first rotating shaft 10, preventing the components from shifting or jamming during movement and ensuring the overall structural coordination. The first limiting slider 5 is slidably connected in the first limiting slide 4, and the end of the first limiting slider 5 away from the limiting plate 6 passes through the first limiting slide 4 and is fixedly connected to the screen plate 3. Multiple limiting grooves 8 are provided in the middle of the right side of the vibrating screen 1 near the rear of the first limiting slide 4. One end of the limiting bolt 7 passes through the limiting plate 6 and can extend into the limiting groove 8. Therefore, when the screen plate 3 rotates, it will drive the first limiting slider 5 to move synchronously. The displacement of the first limiting slider 5 will also drive the limiting plate 6 to move synchronously, thereby making the limiting bolt 7 cooperate with the limiting groove 8 at different positions. At this time, the operator only needs to insert the limiting bolt 7 into the limiting groove 8 at the corresponding position to effectively ensure the stable locking of the tilt angle of the screen plate 3. Meanwhile, when the operator needs the screen plate 3 to have an adaptive angle adjustment function, simply loosen the limiting bolt 7 to disengage it from the limiting groove 8. At this time, the limiting plate 6 is released from the limiting constraint, and the screen plate 3 can then achieve adaptive angle adjustment according to changes in material load. When it is necessary to limit the screen plate 3 to a specific stable screening speed, the operator can tighten the limiting bolt 7 so that one end is embedded in the corresponding limiting groove 8. Therefore, the limiting plate 6 will transmit the constraint to the screen plate 3 through the first limiting slider 5, limiting the tilt amplitude of the screen plate 3. Thus, the operator can achieve precise control of the tilt angle of the screen plate 3 by adjusting the fixed position of the limiting plate 6 on the vibrating screen 1, thereby achieving the purpose of limiting the screening speed.

[0021] A feeding plate 9 is fixedly connected to the top of the front side of the vibrating screen 1, and one end of the feeding plate 9 extends directly above the screen plate 3. Therefore, the material entering the vibrating screen 1 will first fall onto the feeding plate 9. Relying on the inclined characteristics of the feeding plate 9, the material will slide smoothly along its surface and finally fall accurately onto the screen plate 3, providing a stable material conveying connection for subsequent screening operations.

[0022] In summary, when using this vanadium ore vibrating screen, the vanadium ore material to be screened is first introduced into the feed hopper 2 and enters the equipment through the feed port at the front end of the upper surface of the vibrating screen 1. After entering, the material first falls onto the feed plate 9 and slides smoothly down its surface relying on the inclined characteristics of the feed plate 9. Finally, it is accurately conveyed to the screen plate 3. After the vibrating screen 1 is started, the screen plate 3 screens the material. The vanadium ore particles that meet the preset particle size requirements fall through the screen holes of the screen plate 3 and are discharged through the first discharge port at the bottom of the vibrating screen 1. The material that does not meet the particle size requirements is conveyed backward along the surface of the screen plate 3 and discharged from the second discharge port at the rear end of the vibrating screen 1, thus completing the basic screening operation. If the material enters in a concentrated manner during the screening process, causing a sudden increase in the instantaneous load at the front end of the screen plate 3, the screen plate 3 will adaptively rotate around the first rotating shaft 10, reducing the tilt angle to slow down the material flow speed and prolong the contact time, thus avoiding insufficient screening. At the same time, the rotation of the screen plate 3 will drive the adaptive adjustment component to move, and the first spring 12 and the second spring 13 will be compressed to produce elastic deformation. The auxiliary connecting plate 11 will move downward synchronously, and drive the second limiting slider 15 to slide along the second limiting groove 14 on the inner side of the vibrating screen 1 to ensure the overall structure operates stably in dynamic operation. If the operator needs to switch working modes, it can be achieved through the cooperation of the limiting bolt 7 and the limiting groove 8: when the screen plate 3 needs to maintain its adaptive adjustment capability, loosen the limiting bolt 7 so that it is disengaged from the limiting groove 8 on the right side of the vibrating screen 1, the limiting plate 6 is released from constraint, and the screen plate 3 can flexibly adjust its angle according to the material load; when the screen plate 3 needs to be limited to a specific screening speed, tighten the limiting bolt 7 so that one end of it passes through the limiting plate 6 and extends into the corresponding limiting groove 8. At this time, the limiting plate 6 slides along the arc-shaped first limiting slide 4 through the first limiting slider 5, and the center of the first limiting slide 4 is concentric with the axis of the first rotating shaft 10 to limit the rotation amplitude of the screen plate 3, and precisely control the tilt angle of the screen plate 3 to stabilize the screening speed.

[0023] Furthermore, throughout the entire vanadium ore screening process using vibrating screen 1, a cyclone dust collector continuously extracts dust generated inside the equipment via suction pipe 16, effectively preventing dust particles from spreading into the air and causing pollution. The entire process achieves both adaptive angle adjustment of the screen plate 3 and precise manual control of the screening speed, balancing screening effectiveness, operational stability, and environmental requirements, making it highly adaptable to vanadium ore screening scenarios.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
