Description

Technical Field

[0001] This utility model belongs to the field of mineral processing technology, specifically, it relates to a multi-stage separation device for precision zirconium-titanium minerals. Background Technology

[0002] Zirconium-titanium minerals are key raw materials for modern industry, playing an irreplaceable role in aerospace, new energy batteries, and high-end ceramics. With the rapid development of science and technology, various industries have put forward higher requirements for the purity and quality of zirconium-titanium minerals. Efficient and precise separation technology has become the core link to improve resource utilization and ensure product quality.

[0003] Currently, existing zirconium-titanium mineral separation equipment still has the following defects in material conveying and sorting processes. In terms of material conveying, traditional devices mostly use continuous feeding, which easily leads to a large accumulation of material on the surface of the magnetic separator roller, making it impossible for some material to fully contact the magnetic field, thus reducing separation efficiency and accuracy.

[0004] In the sorting process, most equipment relies on a single magnetic field or simple grading and screening, which makes it difficult to make full use of the magnetic differences between different minerals. It is impossible to achieve fine separation of strongly magnetic impurities, weakly magnetic ilmenite and target zirconium titanium minerals, resulting in the final product purity failing to meet the standards. Therefore, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a multi-stage separation device for precision zirconium-titanium minerals that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A multi-stage separation device for precision zirconium-titanium minerals includes a frame and three magnetic rollers: a first magnetic roller, a second magnetic roller, and a third magnetic roller, all rotatably connected to the frame. Each magnetic roller has a distribution box located diagonally below it, with an open upper end and a discharge port on its lower side wall. The distribution box is fixedly connected to the frame. A recovery mechanism is located directly below each magnetic roller for collecting the material separated by each roller. A storage box with an open upper end is fixedly connected to the frame. A discharge box communicates with the storage box, with its lower end in contact with the first magnetic roller and a gap between one side of the discharge box and the outer wall of the first magnetic roller. A roller is disposed within the discharge box, with grooves evenly spaced around its circumference. A rotating shaft is rotatably connected inside the discharge box, and the roller is fixedly connected to the rotating shaft.

[0008] In order to drive the rotating shaft to rotate the drum, preferably, a second motor is fixedly installed on the feeding box, and one end of the rotating shaft is fixedly connected to the output end of the second motor.

[0009] To drive the three sets of magnetic rollers to rotate synchronously, preferably, pulleys are fixedly installed on the first, second, and third magnetic rollers. The pulley on the first magnetic roller is connected to the pulley on the second magnetic roller via belt one, and the pulley on the second magnetic roller is connected to the pulley on the third magnetic roller via belt two. A motor is fixedly installed on the frame, and the first magnetic roller is fixedly connected to the output end of the motor.

[0010] Preferably, the first magnetic roller has a weak magnetic field, the second magnetic roller has a medium magnetic field, and the third magnetic roller has a strong magnetic field.

[0011] In order to scrape the separated material from the magnetic roller into the collection box, the recycling mechanism preferably includes a collection box with an open top and a closed bottom, the collection box being fixedly connected to the frame and located directly below each magnetic roller; it also includes a scraper connected to the collection box and in contact with each magnetic roller.

[0012] To ensure a tight fit between the scraper and the magnetic roller, a connecting seat is fixedly connected to the collection box, a guide rod is slidably connected to the connecting seat, the scraper is fixedly connected to the guide rod, and a spring is sleeved on the guide rod. One end of the spring is fixedly connected to the connecting seat, and the other end is fixedly connected to the scraper.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0014] This invention utilizes the intermittent gripping of materials in the feed hopper by the grooves of the rollers, allowing the materials to fall evenly and intermittently onto the surface of the first magnetic roller. This avoids material accumulation, ensures full contact between the materials and the magnetic roller, and improves the accuracy of subsequent separation. By setting up three levels of magnetic rollers with weak, medium, and strong magnetic fields based on the differences in the magnetic properties of different minerals, a gradient sorting from coarse to fine is achieved, effectively improving the separation purity of zirconium and titanium minerals.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0023] Example 1:

[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 A multi-stage separation device for precision zirconium-titanium minerals includes a frame 1 and three magnetic rollers: a first magnetic roller 101, a second magnetic roller 102, and a third magnetic roller 103, all rotatably connected to the frame 1. Each magnetic roller has a distribution box 104 located diagonally below it. The upper end of the distribution box 104 is open, and the lower end sidewall of the distribution box 104 has a discharge port 105. The distribution box 104 is fixedly connected to the frame 1. A recovery mechanism is located directly below each magnetic roller for recovering the separated material. Material is collected; a storage box 4 with an open top is fixedly connected to the frame 1; a feeding box 401 is connected to the storage box 4, wherein the lower end of the feeding box 401 is in contact with the first magnetic roller 101, and there is a gap between one side of the feeding box 401 and the outer wall of the first magnetic roller 101; a roller 402 is disposed in the feeding box 401, wherein grooves 403 are equidistantly arranged on the circumference of the roller 402; a rotating shaft 405 is rotatably connected inside the feeding box 401, and the roller 402 is fixedly connected to the rotating shaft 405.

[0025] A second motor 404 is fixedly installed on the feeding box 401, and one end of the rotating shaft 405 is fixedly connected to the output end of the second motor 404.

[0026] Each of the first magnetic roller 101, the second magnetic roller 102, and the third magnetic roller 103 is fixedly equipped with a pulley. The pulley on the first magnetic roller 101 is connected to the pulley on the second magnetic roller 102 via belt 1 201. The pulley on the second magnetic roller 102 is connected to the pulley on the third magnetic roller 103 via belt 2 202. A motor 1 2 is fixedly installed on the frame 1. The first magnetic roller 101 is fixedly connected to the output end of the motor 1 2.

[0027] The first magnetic roller 101 has a weak magnetic field, the second magnetic roller 102 has a medium magnetic field, and the third magnetic roller 103 has a strong magnetic field.

[0028] In use, the zirconium-titanium mineral raw materials to be separated are put into the storage box 4. The raw materials flow from the storage box 4 into the feed box 401 connected to it under their own gravity. Then, the motor 404 is started, driving the rotating shaft 405 to rotate, which in turn causes the roller 402 installed on the rotating shaft 405 to start rotating. The grooves 403 equidistantly arranged on the circumference of the roller 402 will intermittently grab the material in the feed box 401 during the rotation of the roller 402. As the roller 402 rotates, when the grooves 403 rotate to the gap position between the feed box 401 and the first magnetic roller 101, the material falls from the grooves 403 under the action of gravity, and falls evenly and intermittently on the surface of the first magnetic roller 101. This avoids the accumulation of material on the surface of the first magnetic roller 101 and ensures that the material contacts the magnetic roller with appropriate thickness and uniform distribution. For example, if a large amount of material continuously accumulates on the surface of the magnetic roller, some material will not be able to fully interact with the magnetic field, affecting the separation effect. Intermittent conveying allows the material in each time period to be effectively subjected to magnetic separation, improving the accuracy of subsequent separation.

[0029] When motor 12 starts, the output torque drives the first magnetic roller 101 to rotate. The pulley of the first magnetic roller 101 drives the pulley of the second magnetic roller 102 to rotate via belt 1201. The second magnetic roller 102 then drives the third magnetic roller 103 via belt 2202, so that the three magnetic rollers rotate synchronously and in the same direction.

[0030] As the magnetic roller rotates, the material falling on the surface of the first magnetic roller 101 enters the magnetic field area. Strongly magnetic impurities are adsorbed on the surface of the first magnetic roller 101 under the action of the weak magnetic field. Non-magnetic and weakly magnetic materials such as zirconium and titanium minerals are detached from the first magnetic roller 101 by gravity and centrifugal force caused by the rotation of the magnetic roller and fall into the distribution box 104 below it. Then, they enter the next stage of magnetic separation through the discharge port 105 at the lower end of the distribution box 104. At the same time, the strongly magnetic impurities are carried by the magnetic roller to the recycling mechanism for collection.

[0031] The material exiting from the discharge port 105 of the first magnetic roller 101 distribution box 104 enters the working area of ​​the second magnetic roller 102. The second magnetic roller 102 is a medium magnetic field. The material rotates with the second magnetic roller 102. Under the action of the medium magnetic field, weakly magnetic minerals such as ilmenite will be adsorbed on the surface of the second magnetic roller 102. Minerals with weaker magnetic properties or non-magnetic properties, such as zircon, will be separated from the second magnetic roller 102 by gravity, centrifugal force, etc., and fall into the distribution box 104 below it. The material then enters the magnetic separation stage of the third magnetic roller 103 through the discharge port 105. At the same time, the weakly magnetic minerals are carried by the magnetic roller to the recycling mechanism for collection.

[0032] Material entering the working area of ​​the third magnetic roller 103, which is a strong magnetic field, will have residual weak magnetic impurities adsorbed onto the surface of the third magnetic roller 103 under the magnetic force of the strong magnetic field as the roller rotates. High-purity zircon and other minerals will be detached from the third magnetic roller 103 by gravity and centrifugal force and fall into the distribution box 104 below it. The zircon will be collected through the discharge port 105. At the same time, the residual weak magnetic impurities will be carried by the magnetic roller to the recycling mechanism for collection.

[0033] In summary, by utilizing the differences in magnetic properties of different minerals (such as weakly magnetic / non-magnetic zircon, weakly magnetic ilmenite, and different magnetic properties of strongly magnetic impurities), the first magnetic roller 101 uses a weak magnetic field to first screen out strongly magnetic impurities to avoid interfering with subsequent sorting; the magnetic field in the second magnetic roller 102 captures ilmenite and other impurities; and the strong magnetic field in the third magnetic roller 103 performs fine separation, achieving gradient sorting from coarse to fine and improving the purity of zircon-titanium mineral separation.

[0034] The material distribution box 104 opens to receive the material thrown down by the magnetic roller, and the discharge port 105 guides the material to the next magnetic roller in a directional manner, ensuring orderly flow of materials, avoiding accumulation and mixing, and improving the continuity and efficiency of sorting.

[0035] Example 2:

[0036] Reference Figure 3 , Figure 5 A multi-stage separation device for precision zirconium-titanium minerals is basically the same as that in Example 1. Furthermore, the recovery mechanism includes a collection box 3 with openings at both the upper and lower ends. The collection box 3 is fixedly connected to the frame 1 and is located directly below each magnetic roller. It also includes a scraper 301, which is connected to the collection box 3 and is in contact with each magnetic roller.

[0037] When the magnetic roller rotates, the sorted materials adsorbed on the surface (such as strong magnetic impurities, ilmenite, etc.) move with the magnetic roller. When they come into contact with the scraper 301, the scraper 301 blocks the relative movement with the rotating magnetic roller, and the materials are scraped off and fall into the collection box 3 below. They are collected or transported to subsequent stages through the opening of the collection box 3. In this way, the relative movement between the scraper 301 and the magnetic roller is used to forcibly scrape off the sorted materials adsorbed by the magnetic roller, instead of simply relying on the magnetic field to weaken the unloading. This avoids incomplete unloading caused by uneven magnetic field distribution and overly strong material adsorption, ensuring accurate collection of materials after each stage of magnetic separation, improving the yield and purity of zirconium-titanium mineral separation, and preventing strong magnetic impurities from remaining on the magnetic roller and mixing into the next stage of separation.

[0038] In practical implementation, the scraper 301 is made of wear-resistant material to reduce friction loss during magnetic roller rotation and extend the service life of magnetic roller and scraper 301. At the same time, the upper and lower openings of the collection box 3 are designed to adapt to magnetic roller material discharge and subsequent processes, and can be flexibly connected to hoppers, conveyor belts, etc., which facilitates the centralized processing and transfer of sorted materials and improves the continuity and automation of the zirconium-titanium ore sorting production line.

[0039] Example 3:

[0040] Reference Figure 3 , Figure 5 , Figure 6 A multi-stage separation device for precision zirconium-titanium minerals is basically the same as that in Example 1. Furthermore, a connecting seat 302 is fixedly connected to the collection box 3, a guide rod 303 is slidably connected to the connecting seat 302, a scraper 301 is fixedly connected to the guide rod 303, and a spring 304 is sleeved on the guide rod 303. One end of the spring 304 is fixedly connected to the connecting seat 302, and the other end is fixedly connected to the scraper 301.

[0041] When the magnetic roller rotates, if there is material accumulation or jamming on the surface (such as large particles of impurities), the scraper 301 is subjected to the squeezing force of the material, and the compression spring 304 slides along the guide rod 303 toward the connecting seat 302 to avoid large particles. After the material passes through, the spring 304 pushes the scraper 301 back to its original position, continuously adhering to the magnetic roller to ensure the scraping effect. During normal rotation of the magnetic roller, the scraper 301 adheres tightly with the help of the spring 304, stably scraping off the adsorbed material. The spring 304 provides elastic preload, allowing the scraper 301 to adapt to the state of the material on the surface of the magnetic roller (such as particles of impurities). The particle size and adsorption tightness are adaptively fine-tuned, ensuring scraping force (removing adsorbed material) while avoiding damage to the magnetic roller and scraper 301 from rigid contact, thus extending the service life of the equipment. At the same time, the continuous elastic force of the spring 304 keeps the scraper 301 in close contact with the magnetic roller, maintaining a stable scraping effect regardless of magnetic roller wear or material fluctuations. This avoids material residue and mixing caused by loose scraper 301, ensuring accurate collection of material after each stage of magnetic separation, improving the consistency of zirconium and titanium mineral separation, and reducing the fluctuation of sorting quality caused by unstable scraping.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
