Abstract
Description
Technical Field
[0001] This utility model relates to the field of non-metallic mineral preparation technology, and in particular to an iron removal device for non-metallic mineral preparation. Background Technology
[0002] In the preparation of non-metallic minerals (such as quartz, feldspar, talc, etc.), iron impurities (including iron filings, iron oxides, etc.) are often mixed in with the raw materials. These impurities affect the purity, whiteness, and mechanical properties of mineral products, especially adversely affecting applications in high-end ceramics, electronic materials, and other fields. Therefore, iron removal is a key step in the deep processing of non-metallic minerals, and the efficiency and reliability of iron removal equipment are directly related to the quality of the final product.
[0003] The permanent magnets used to adsorb iron impurities in the device are mostly fixed. When the amount of iron impurities adsorbed on the surface of the permanent magnet reaches a certain level, its adsorption capacity will decrease significantly. At this time, it is necessary to stop feeding and disassemble the device to clean the iron impurities on the surface of the permanent magnet. This not only forces the iron removal process to be interrupted, affecting the continuity of production, but also the disassembly and cleaning operation is cumbersome and time-consuming, increasing labor costs. Therefore, we have disclosed an iron removal device for non-metallic mineral preparation to meet people's needs. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1 - Figure 4 The embodiments provided by this utility model are as follows: Iron removal device for non-metallic mineral preparation includes a box body 1. A feed pipe 6 is fixedly installed on the inner top wall of the box body 1. An upper bevel gear 11 is rotatably sleeved on the feed pipe 6. A round box 8 is fixedly installed at the bottom of the upper bevel gear 11 through four connecting rods 14. A drive mechanism for driving the upper bevel gear 11 to rotate is installed on the side of the box body 1. like Figure 1 , Figure 2 and Figure 3 As shown, the drive mechanism includes a motor 3 fixedly mounted on the side of the housing 1. A rotating shaft 7 is fixedly mounted on the output end of the motor 3. One end of the rotating shaft 7 passes through the outer side of the housing 1 and is fixedly mounted with a lower bevel gear 12. The lower bevel gear 12 meshes with an upper bevel gear 11. Starting the motor 3 will cause the rotating shaft 7 to rotate, and the rotation of the rotating shaft 7 will drive the lower bevel gear 12 to rotate.
[0019] The inner top wall of the round box 8 has a plurality of evenly arranged column holes 15. Permanent magnet columns 9 are slidably installed in the plurality of column holes 15. A disc 16 is fixedly installed at the bottom of the plurality of permanent magnet columns 9. A convex ring 17 is fixedly installed at the bottom of the disc 16. Two arc-shaped sliders 18 are slidably installed on the convex ring 17. The inner bottom wall of the box 1 is fixedly installed with a discharge pipe 4, and the side of the discharge pipe 4 is equipped with a threaded moving mechanism for a movable arc-shaped slider 18.
[0020] like Figure 4As shown, the threaded moving mechanism includes a fixed plate 22 fixedly installed on the side of the discharge pipe 4. The top of the fixed plate 22 is provided with a rotating hole 5, and a rotating rod 23 is rotatably installed in the rotating hole 5. The rotating hole 5 is used to limit the rotating rod 23 so that it can only rotate and cannot move up and down. The rotating rod 23 is provided with an external thread 20, and an internal thread sleeve 19 is threaded onto the external thread 20. The top of the internal thread sleeve 19 is fixedly connected to the bottom of the arc-shaped slider 18. In use, first turn the knob 21 clockwise, which causes the rotating rod 23 and the external thread 20 to rotate clockwise, thereby causing the internal thread sleeve 19 to move upward. The movement of the internal thread sleeve 19 drives the arc-shaped slider 18, the convex ring 17, and the disc 16 to move upward. The movement of the disc 16 causes multiple permanent magnet columns 9 to move upward, exposing a portion of them. When the amount of iron on the multiple permanent magnet columns 9 increases, thus reducing the adsorption effect, the knob 21 can be turned clockwise to continue moving the permanent magnet columns 9 upward, allowing the portion of the permanent magnet columns 9 that has not adsorbed iron to continue to be exposed, facilitating the continued adsorption of iron. When the permanent magnet columns 9 move upward to their maximum position, the feeding of the hopper 2 is stopped. Then, another collection box is placed below the discharge pipe 4. Then, the knob 21 is turned counterclockwise, causing the top of the permanent magnet column 9 to enter the column hole 15. The iron on the permanent magnet column 9 is scraped off through the column hole 15, and the scraped iron is thrown out into the other collection box by the centrifugal force generated by the rotation of the disc 8, completing the collection.
[0021] The non-metallic minerals enter and fall to the top center of the circular box 8 after passing through the feed hopper 2 and feed pipe 6. Starting the motor 3 will cause the rotating shaft 7 to rotate, which in turn drives the lower bevel gear 12 to rotate, which in turn drives the upper bevel gear 11 to rotate. Since one end of the four connecting rods 14 is fixedly connected to the bottom surface of the upper bevel gear 11, the four connecting rods 14 will move in a circular motion. The rotation of the four connecting rods 14 will drive the circular box 8 to rotate. Due to the rotation of the circular box 8, the non-metallic minerals on the circular box 8 will be subjected to outward centrifugal force, thus moving radially outward along the circular box 8. This allows the non-metallic minerals to pass through the gap between the side of the circular box 8 and the inner wall of the box 1, and fall through the discharge pipe 4. A collection box can be placed below the discharge pipe 4 for collection. During the process of the non-metallic minerals moving outward from the top of the circular box 8, they will pass through multiple permanent magnet columns 9. The iron on the non-metallic minerals will be attracted by the permanent magnet columns 9, thus removing iron from the non-metallic minerals.
[0022] like Figure 4 As shown, the inner bottom wall of the housing 1 has two sliding holes. A guide rod 24 is slidably installed in one of the sliding holes. The top end of the guide rod 24 is fixedly installed on the bottom of the arc-shaped slider 18, which is away from the internal threaded sleeve 19. The internal threaded sleeve 19 is slidably installed in the other sliding hole. A knob 21 is fixedly installed at the bottom end of the rotating rod 23. The knob 21 facilitates the rotation of the rotating rod 23.
[0023] like Figure 2 As shown, a gap is left between the outer side of the circular box 8 and the inner wall of the box body 1. The advantage of this design is that it facilitates the passage of non-metallic minerals.
[0024] like Figure 3 As shown, a protective box 10 is fixedly installed on the inner top wall of the housing 1. A clearance hole 13 is provided at the bottom of the protective box 10, and the feed pipe 6 and four connecting rods 14 are located inside the clearance hole 13. The protective box 10 is used to protect the lower bevel gear 12 and the upper bevel gear 11.
[0025] like Figure 3 As shown, a circular hole is provided on the side wall of the protective box 10, and the rotating shaft 7 is rotatably installed in the circular hole. The circular hole facilitates the installation of the rotating shaft 7.
[0026] like Figure 1 and Figure 2 As shown, the top end of the feed pipe 6 extends outside the housing 1 and is fixedly installed with a feed hopper 2. The feed hopper 2 facilitates feeding.
[0027] Working principle: When in use, first turn the knob 21 clockwise, which will cause the rotating rod 23 and the external thread 20 to rotate clockwise, thereby causing the internal thread sleeve 19 to move upward. The movement of the internal thread sleeve 19 will drive the arc-shaped slider 18, the convex ring 17 and the disc 16 to move upward. The movement of the disc 16 will drive multiple permanent magnet columns 9 to move upward and expose a portion of them. The non-metallic minerals enter and fall to the top center of the round box 8 after passing through the feed hopper 2 and feed pipe 6. The motor 3 is started to make the rotating shaft 7 rotate. The rotation of the rotating shaft 7 drives the lower bevel gear 12 to rotate, and the rotation of the lower bevel gear 12 drives the upper bevel gear 11 to rotate. Since one end of the four connecting rods 14 is fixedly connected to the bottom surface of the upper bevel gear 11, the four connecting rods 14 make circular motion. The rotation of the four connecting rods 14 drives the round box 8 to rotate. Due to the rotation of the round box 8, the non-metallic minerals on the round box 8 are subjected to outward centrifugal force, so they move radially around the round box 8. The non-metallic minerals can pass through the gap between the side of the round box 8 and the inner wall of the box 1, and fall through the discharge pipe 4. A collection box is placed below the discharge pipe 4 for collection. During the process of the non-metallic minerals moving around the top of the round box 8, they will pass through multiple permanent magnet columns 9. The iron on the non-metallic minerals is attracted by the permanent magnet columns 9, thereby removing iron from the non-metallic minerals. When the amount of iron on multiple permanent magnet columns 9 increases, thus reducing the adsorption effect, the knob 21 can be turned clockwise to continue moving the permanent magnet columns 9 upwards. This allows the unadsorbed iron portion of the permanent magnet columns 9 to continue to be adsorbed, facilitating further iron adsorption. When the permanent magnet columns 9 move upwards to their maximum position, the feeding from the feed hopper 2 is stopped. Then, another collection box is placed below the discharge pipe 4. The knob 21 is then turned counterclockwise to allow the top of the permanent magnet column 9 to enter the column hole 15. The iron on the permanent magnet column 9 is scraped off through the column hole 15, and the scraped iron is thrown out into another collection box by the centrifugal force generated by the rotation of the circular box 8, completing the collection.
[0028] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
