Description

Technical Field

[0002] Garnet abrasive, made from ground garnet, features high hardness, high temperature resistance, stable chemical properties, uniform particle size, high grinding efficiency, and no scratching. It is suitable for waterjet cutting; sandblasting of various metals, plastics, and wood surfaces; ultra-precision grinding in the machinery industry; precision casting; and grinding of cathode ray tube shells, optical glass, silicon wafers, etc.

[0003] A magnetic separator is a machine that separates materials based on their magnetic properties. Garnet ore contains a certain amount of magnetic mineral particles, so it is necessary to separate the garnet from the magnetic mineral particles during processing. The purpose is to separate the magnetic mineral particles from the garnet sand to obtain a purer garnet sand.

[0004] Ore magnetic separators are divided into drum screening and plate screening. Both of these methods can continuously screen ore, but when processing adsorbed iron ore, the machine needs to be stopped for cleaning, resulting in intermittent shutdowns and reducing overall screening efficiency. Therefore, a dry magnetic separator for garnet tailings is proposed to address the above problems. Utility Model Content

[0024] 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 scope of protection of the present utility model.

[0025] Example 1

[0026] Please see Figure 1-4As shown, a dry magnetic separator for garnet tailings includes a conveyor 1. Side supports 2 are fixedly connected to both sides of the conveyor 1 frame. Several openings 4 are formed on the surface of the side supports 2. Magnetic separation components 3 are installed inside the openings 4. The magnetic separation components 3 include a first rotating disk 31 and a second rotating disk 32 symmetrically distributed along the conveying direction of the conveyor 1. The first rotating disk 31 and the second rotating disk 32 are rotatably connected to two openings 4 respectively. Two magnetic separation cylinders 3 are respectively installed from top to bottom on opposite sides of the first rotating disk 31 and the second rotating disk 32. 3. The magnetic separator 33 includes an inner rod 331, on the surface of which an adsorption cylinder 332 is fitted. Two drive motors 34 are fixedly connected from top to bottom to the side wall of the rotating disk 31. The drive end of the drive motor 34 is fixedly connected to one end of the inner rod 331. A mounting frame 5 is installed on the outside of the rotating disk 32. Both ends of the mounting frame 5 are fixedly connected to the outer wall of the side support 2. Several drive motors 6 are fixedly connected to the surface of the mounting frame 5. The drive end of the drive motor 6 is fixedly connected to the outer wall of the rotating disk 32.

[0027] During operation, garnet tailings are conveyed by conveyor 1 and sorted by magnetic separation component 3. The ore passes through multiple magnetic separation cylinders 33 in sequence. The controller controls the operation of the lower drive motor 34, which drives the lower magnetic separation cylinder 33 to rotate. The magnetic mineral particles in the ore are adsorbed by the rotating adsorption cylinder 332. A large number of magnetic mineral particles are adsorbed on the surface of the adsorption cylinder 332. The controller controls the operation of drive motor 6, which rotates 180° to switch the two adsorption cylinders 332 on the surface of rotating disk 31 and rotating disk 32. The adsorption cylinder 332 with magnetic mineral particles is rotated to the upper side, while the cleaned adsorption cylinder 332 is rotated to the lower side for sorting. Then, the upper adsorption cylinder 332 is pulled laterally, and the magnetic mineral particles on the surface of the adsorption cylinder 332 are scraped off by rotating disk 32. This allows the adsorbed magnetic mineral particles to be cleaned without stopping the machine.

[0028] The inner rod 331 has a groove on its surface, and the inner wall of the adsorption cylinder 332 has a protrusion that is slidably connected to the groove.

[0029] During operation, the inner rod 331 is slidably connected to the adsorption cylinder 332, so that when the drive motor 34 drives the inner rod 331 to rotate, the inner rod 331 drives the adsorption cylinder 332 to rotate.

[0030] The adsorption cylinder 332 includes a magnetic cylinder 3321. Connecting cylinders 3322 without magnetic adsorption properties are fixedly connected to both sides of the magnetic cylinder 3321. The surface of the connecting cylinder 3322 is provided with an annular groove 3323. A limiting disk 35 is installed on one side of the rotating disk 32. The outer wall of the limiting disk 35 is fixedly connected to the side bracket 2, and the upper side wall of the limiting disk 35 is provided with a through hole 36.

[0031] When the adsorption cylinder 332 is not directly above the surface during operation, the connecting cylinder 3322 on one side abuts against the rotating disk 31, and the rotating cylinder on the other side abuts against the limiting disk 35, thereby limiting the adsorption cylinder 332 so that the magnetic cylinder 3321 is located on the conveyor belt of the conveyor 1. When the adsorption cylinder 332 rotates to the top for cleaning, the adsorption cylinder 332 can pass through the limiting disk 35 through the through port 36. The magnetic cylinder 3321 is used to adsorb magnetic mineral particles.

[0032] Several cleaning components 7 are installed on the upper side of the side bracket 2. The cleaning components 7 include several electric slides 71. The electric slides 71 are fixedly installed on the top of the side bracket 2. The bottom of the slider of the electric slide 71 is fixedly connected to an electric push rod 72. The bottom of the side bracket 2 is provided with an inclined surface.

[0033] During operation, when the adsorption cylinder 332 rotates to switch positions, the controller controls the electric push rod 72 to retract. After the adsorption cylinder 332 has switched positions, the controller controls the electric slide 71 to run. The electric slide 71 drives the electric push rod 72 to move directly above the slot 3323. The controller then controls the electric push rod 72 to extend, inserting it into the slot 3323. Subsequently, the electric slide 71 drives the electric push rod 72 to move towards the rotating disk 32. The electric push rod 72 pushes the adsorption cylinder 332 through the rotating disk 32, thereby achieving the automatic cleaning function of magnetic mineral particles on the surface of the adsorption cylinder 332. After the magnetic cylinder 332 passes through the rotating disk 32, the electric slide 71 reverses its direction, thereby driving the adsorption cylinder 332 back to its original position. The cleaned magnetic mineral particles fall onto the side support 2 and slide out along the inclined surface of the side support 2.

[0034] Example 2

[0035] For comparison with Example 1, please refer to Figure 5 As shown, this utility model provides another embodiment. An adjustment component 8 is installed on the surface of the conveyor 1. The adjustment component 8 includes two side baffles 81. The bottom end of the side baffles 81 is fixedly connected to the frame of the conveyor 1. A fixing plate 82 and a scraper 83 are installed on the opposite side of the two side baffles 81 from top to bottom. The two ends of the fixing plate 82 are fixedly connected to the side baffles 81. The two ends of the scraper 83 are slidably connected to the side baffles 81. An electric push rod 84 is fixedly connected to the center of the fixing plate 82, and the driving end of the electric push rod 84 is fixedly connected to the top end of the scraper 83.

[0036] During operation, the controller controls the operation of the electric push rod 84. The electric push rod 84 extends and retracts to adjust the height of the scraper 83, thereby adjusting the distance between the scraper 83 and the conveyor belt. When the ore passes through the adjusting component 8, the scraper 83 flattens the ore. The thickness of the ore after flattening is adjusted by different heights of the scraper 83, thereby avoiding the accumulation of ore and affecting the magnetic attraction effect. When larger ore particles pass through, the height of the scraper 83 can be increased to allow them to pass through smoothly. The side baffle 81 intercepts the incoming ore to prevent it from falling.

[0037] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers should be selected and electrically connected to conveyor 1, drive motor 34, drive motor 6, electric push rod 72, and electric push rod 84, according to the actual situation, to meet control requirements. Specific connections and control sequences should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of electrical control.

[0038] The parts of the device not covered herein are the same as or can be implemented using existing technologies.

[0039] Working principle: Garnet tailings are conveyed by conveyor 1 and sorted by magnetic separation component 3. The ore passes through multiple magnetic separation cylinders 33 in sequence. The controller controls the lower drive motor 34 to rotate, which in turn drives the lower magnetic separation cylinders 33 to rotate. The magnetic particles in the ore are adsorbed by the rotating adsorption cylinders 332. A large number of magnetic particles are adsorbed on the surface of the adsorption cylinders 332. The controller controls the second drive motor 6 to rotate 180°, switching between the two adsorption cylinders 332 on the rotating disk 31 and the rotating disk 32, thereby adsorbing the magnetic particles. The adsorption cylinder 332 rotates to the upper side, while the cleaned adsorption cylinder 332 rotates to the lower side for sorting. The controller controls the extension of the electric push rod 72, which extends and inserts into the slot 3323. Then, the electric slide table 71 drives the electric push rod 72 to move towards the rotating disk 32. The electric push rod 72 pushes the adsorption cylinder 332 to move through the rotating disk 32, and the rotating disk 32 scrapes away the magnetic mineral particles on the surface of the adsorption cylinder 332, thereby realizing the automatic cleaning function of the magnetic mineral particles on the surface of the adsorption cylinder 332, and realizing the cleaning of the adsorbed magnetic mineral particles without stopping the machine.

[0040] The controller controls the operation of the electric push rod 84. The electric push rod 84 extends and retracts to adjust the height of the scraper 83, thereby adjusting the distance between the scraper 83 and the conveyor belt. When the ore passes through the adjusting component 8, the scraper 83 flattens the ore. The thickness of the ore after flattening is adjusted by different heights of the scraper 83, thereby avoiding the accumulation of ore and affecting the magnetic attraction effect. When larger ore particles pass through, the operator can adjust the height of the scraper 83 to allow them to pass smoothly.
