Description

Technical Field

[0001] The invention relates to the technical field of tailings treatment, in particular to a magnetic separator which is convenient for feeding. Background Art

[0002] ‌Ore magnetic separator‌ is a device that uses a magnetic field to separate magnetic substances in ores. It is mainly used to remove or extract magnetic minerals from ores. It is widely used in mining, metallurgy, chemistry, construction and other industries. Especially for the treatment of tailings in some mines, these tailings still contain a large amount of magnetic substances that need to be removed. It has a significant effect on improving ore quality and recovery rate, a wide range of applications, technological progress, compliance with green production concepts and significant economic benefits.

[0003] Generally speaking, magnetic separators are used to separate tailings after crushing. However, in the actual working process, there will still be larger pieces of tailings that have not been crushed or the crushing effect is not ideal. Because the ore with relatively smaller particle size can significantly improve the magnetic separation effect by increasing the contact surface compared to the ore with larger particle size during the magnetic separation process, and the ore with better crushing effect will also have a better dissociation effect between the magnetic material inside and the ore, further improving the overall magnetic separation effect. However, the ore with relatively poor crushing effect or not effectively crushed will have a greater interference with the effect and efficiency of the overall magnetic separation work, and there will be problems of incomplete magnetic separation or even no magnetic separation.

The crushing mechanism 5 It is slidably connected to the inside of the feed box 3, and the crushing mechanism 5 is located above the feed channel 4. The crushing mechanism 5 is used to impact and crush the tailings in the feed channel 4. The crushing mechanism 5 includes a crushing box 501 and a pressure column 502. The crushing box 501 is slidably connected to the inside of the feed box 3, and the crushing box 501 is located above the feed channel 4 in a non-sliding state. The pressure column 502 is hinged to the middle of the upper surface of the crushing box 501, and the pressure column 502 is slidably connected to the inside of the feed box 3. A turntable 9 is hinged on one side of the pressure column 502. A motor 10 is fixedly connected to the inside of the feed box 3. The output end of the motor 10 is fixedly connected to a wheel 11 through a coupling. The surface of the wheel 11 is transmission-connected to the turntable 9 through a transmission belt.

[0038] Among them, no material is sent into the feed box 3 through the feed channel 4. At this time, the motor 10 drives the turntable 9 to rotate, and the crushing box 501 can be driven by the pressure column 502 to perform a cyclic downward impact, and the material on the surface of the shaking plate 701 is impacted and crushed, so as to crush the incompletely crushed or unbroken tailings material again, to ensure that the material entering the magnetic separation box 1 is in a completely crushed state, to improve the magnetic separation effect, and when the material enters the magnetic separation box 1, it falls on the surface of the magnetic separation roller 2 due to the blocking effect of the baffle 27, and through the rotation effect of the magnetic separation roller 2, the material contacts the three magnetic separation rollers 2 in turn and is magnetically separated. In the process of rotation of the magnetic separation roller 2, the scraper 28 is used to scrape the metal raw material magnetically attracted to the surface of the magnetic separation roller 2, and it is discharged through the discharge port 29, which can prevent the residual material on the surface of the magnetic separation roller 2 from affecting the effect of magnetic adsorption, and further improve the stability of the magnetic separation work.

[0039] The shaking mechanism 7 is rotatably connected to the inside of the feed box 3. The shaking mechanism 7 is used to shake and screen the materials. The shaking mechanism 7 includes a shaking plate 701, two guide wheels 702 and two push rods 703. The shaking plate 701 is rotatably connected to the inside of the feed box 3, and the shaking plate 701 is located below the crushing box 501. The two guide wheels 702 are symmetrically rotatably connected to the inside of the feed box 3, and the two guide wheels 702 are symmetrically located on both sides below the shaking plate 701. The two push rods 703 are respectively hinged to the surfaces of the opposite sides of the two guide wheels 702. The other end of the push rod 703 is hinged to the bottom of the shaking plate 701, and the rotation directions of the two guide wheels 702 are opposite. The sides of the two guide wheels 702 that are away from each other are both rotated. A driven wheel 21 is dynamically connected, and a meshing groove 22 is provided inside the driven wheel 21. A ratchet 23 is fixedly connected to the surface of the guide wheel 702 close to the driven wheel 21. The ratchet 23 is rotatably connected to the inside of the driven wheel 21 through the meshing groove 22. The ratchet 23 is unidirectionally meshed with the meshing groove 22, and the meshing directions of the two ratchets 23 and the two meshing grooves 22 are the same. The movement directions of the two push rods 703 are opposite. Two driving wheels 24 are symmetrically rotatably connected on both sides of the feed box 3. A belt 25 is transmission-connected between the driven wheel 21 and the driving wheel 24. Rings 26 are fixedly connected to both sides of the surface of the crushing box 501. The rings 26 are fixedly connected to one side of the belt 25, and the two rings 26 are staggered on the same horizontal plane.

[0040] Among them, during the process of the crushing box 501 sliding downward and impacting, since the ratchet teeth 23 and the meshing groove 22 are in a one-way meshing state, the effect of the ring 26 driving the driven wheel 21 to rotate through the belt 25 does not drive the guide wheel 702 to rotate. At this time, the shaking plate 701 is in a stationary state. During the lifting of the crushing box 501, the belt 25 is driven to rotate through the rings 26 on both sides thereof. At this time, the driven wheel 21 rotates following the belt 25. Due to the one-way meshing effect between the ratchet teeth 23 and the meshing groove 22, the ratchet teeth 23 rotates following the driven wheel 21, thereby driving the guide wheel 702 to rotate. Since the two guide wheels 702 and the two push rods 703 move in opposite directions, the two sides of the shaking plate 701 are pushed upward and pulled downward by the two push rods 703 at this time, thereby forming a reciprocating shaking effect, thereby shaking and loosening the materials hit on its surface, and preparing for the next impact.

[0041] The scraping and pushing mechanism 8 is slidably connected to the surface of the shaking mechanism 7. The scraping and pushing mechanism 8 is used to scrape and separate the materials adhered to the surface of the shaking mechanism 7. The scraping and pushing mechanism 8 includes a scraping bar 801, a guide tooth 802 and a positioning column 803. The scraping bar 801 is slidably connected to the upper surface of the shaking plate 701. One side of the scraping bar 801 is fixedly connected to a connecting frame 14. The connecting frame 14 is slidably connected to one side of the surface of the shaking plate 701. The guide tooth 802 is rotatably connected to the inside of the connecting frame 14, and the upper and lower ends of the guide tooth 802 are fixedly connected to the upper and lower ends of the guide tooth 802. The sides are respectively engaged with the upper and lower sides of the connecting frame 14, the positioning column 803 is fixedly connected to one side of the surface of the shaking plate 701, the internal rotation of the feed box 3 is connected with the guide column 15, the guide column 15 is fixedly connected to the guide tooth 802, the positioning column 803 is plugged into the guide column 15 at one end away from the shaking plate 701, the guide column 15 is fixedly connected to the inside of the guide column 15 with a gear ring 16, the end of the positioning column 803 inserted into the guide column 15 is fixedly connected with a gear disk 17, the gear disk 17 is engaged with the gear ring 16, and the positioning column 803 and the guide tooth 802 are arranged through.

[0042] Among them, when the shaking plate 701 is shaking, the positioning column 803 is driven to rotate. At this time, the positioning column 803 drives the guide column 15 to rotate through the meshing effect of the toothed disk 17 and the toothed ring 16, and the guide column 15 will drive the guide tooth 802 to rotate. Since the upper and lower sides of the guide tooth 802 are respectively meshed with the upper and lower sides of the connecting frame 14, the connecting frame 14 will slide reciprocatingly along the shaking plate 701 at this time, so as to scrape and loosen the material on the surface of the shaking plate 701, and force the fine materials tightly adhered to the surface of the shaking plate 701 due to the impact to separate from the shaking plate 701, thereby improving the utilization of materials and ensuring the working effect of the second impact and crushing.

[0043] The material-dispensing mechanism 6 is rotatably connected to the inside of the crushing mechanism 5, and the material-dispensing mechanism 6 is rotatably connected to the inside of the feed channel 4. The material-dispensing mechanism 6 is used to slow down the material flowing through the inside of the feed channel 4. The material-dispensing mechanism 6 includes a driver 601, a rotating shaft 602, and a plurality of thumbwheels 603. The driver 601, the rotating shaft 602, and the thumbwheels 603 are all slidably connected to the inside of the crushing box 501. The rotating shaft 602 is located below the driver 601. The surface of the rotating shaft 602 is symmetrically fixedly connected to two connecting wheels 12. The surface of the connecting wheel 12 is transmission-connected to both ends of the driver 601 through a transmission belt. The plurality of thumbwheels 603 are evenly fixedly connected to the rotating shaft 602. The surface of the crushing box 501 is provided with a connecting groove 13 at the bottom, the dial wheel 603 is rotatably connected to the crushing box 501 through the connecting groove 13, and the dial wheel 603 is slidably connected to the crushing box 501 through the connecting groove 13, the interior of the crushing box 501 is slidably connected with a connecting plate 18, the driver 601 is fixedly connected to the middle part of the connecting plate 18, the two ends of the connecting plate 18 are symmetrically fixedly connected with connecting columns 19, the other ends of the two connecting columns 19 are symmetrically rotatably connected to the surface of the rotating shaft 602, the top of the connecting plate 18 and located on both sides of the driver 601 are symmetrically fixedly connected with two top springs 20, and the other end of the top spring 20 is fixedly connected to the inside of the crushing box 501.

[0044] Among them, when the crushing box 501 does not descend, the connecting plate 18, the rotating shaft 602 and the thumbwheel 603 will fall due to the effect of gravity. At this time, a part of the thumbwheel 603 will extend outward to the bottom of the crushing box 501 through the connecting groove 13, and the driver 601 drives the rotating shaft 602 to rotate through the connecting wheel 12. At this time, several thumbwheels 603 rotate synchronously to move the material inside the feed channel 4 toward the end away from the magnetic separation box 1. On the one hand, it can slow down the speed of the material rolling and prevent the amount of material entering the magnetic separation box 1 in a short time from being too large and affecting the magnetic separation effect of the magnetic separation roller 2 on the material. On the other hand, it can move the material pile. In order to prevent blockage caused by mutual squeezing and ensure normal feeding, during the gradual downward impact of the crushing box 501, the dial wheel 603 will first contact the shaking plate 701 and be pushed upward. At this time, the dial wheel 603 will be retracted into the inside of the crushing box 501 to prevent affecting the working effect of impact crushing. During the upward movement of the crushing box 501, the dial wheel 603 will extend toward the outside of the crushing box 501 again, and the force of the dial wheel 603 extending outward is guaranteed by the top spring 20. At this time, the rotation of the dial wheel 603 will also move the material on the surface of the shaking plate 701, further improving the loosening effect of the material.

[0045] The specific working principle and use method of the present invention are explained in detail below: when in use, in the first step, the material is fed into the feed box 3 through the feed channel 4, at which time the motor 10 drives the turntable 9 to rotate, and the crushing box 501 can be driven by the pressure column 502 to perform a cyclic reciprocating downward impact, and the material on the surface of the shaking plate 701 is impacted and crushed, so as to crush the incompletely crushed or unbroken tailings material again, so as to ensure that the material entering the magnetic separation box 1 is in a completely crushed state, improve the magnetic separation effect, and when the material enters the magnetic separation box 1, it falls on the surface of the magnetic separation roller 2 through the blocking effect of the baffle 27, and through the rotation effect of the magnetic separation roller 2, the material sequentially contacts with the three magnetic separation rollers 2 and is magnetically separated. In the process of the rotation of the magnetic separation roller 2, the metal raw material magnetically attracted to the surface of the magnetic separation roller 2 is scraped by the scraper 28 and discharged through the discharge port 29;

[0046] In the second step, during the downward sliding and impacting process of the crushing box 501, since the ratchet teeth 23 and the meshing groove 22 are in a one-way meshing state, the effect of the ring 26 driving the driven wheel 21 to rotate through the belt 25 does not drive the guide wheel 702 to rotate. At this time, the shaking plate 701 is in a stationary state. During the lifting process of the crushing box 501, the rings 26 on both sides thereof drive the belt 25 for transmission. At this time, the driven wheel 21 rotates following the belt 25. Due to the one-way meshing effect between the ratchet teeth 23 and the meshing groove 22, the ratchet teeth 23 rotates following the driven wheel 21, thereby driving the guide wheel 702 to rotate. Since the two guide wheels 702 and the two push rods 703 move in opposite directions, the two sides of the shaking plate 701 are respectively pushed upward and pulled downward by the two push rods 703, thereby forming a reciprocating shaking effect, thereby shaking and loosening the materials impacted on its surface;

[0047] In the third step, while the shaking plate 701 is shaking, the positioning column 803 is driven to rotate. At this time, the positioning column 803 drives the guide column 15 to rotate through the meshing effect of the toothed disc 17 and the toothed ring 16. The guide column 15 will drive the guide tooth 802 to rotate. Since the upper and lower sides of the guide tooth 802 are respectively meshed with the upper and lower sides of the connecting frame 14, the connecting frame 14 will slide back and forth along the shaking plate 701, thereby scraping and loosening the material on the surface of the shaking plate 701, and forcing the fine materials that are tightly adhered to the surface of the shaking plate 701 due to the impact to separate from the shaking plate 701.

[0048] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
