Description

Technical Field

[0001] This utility model relates to the field of slag magnetic separation technology, specifically to a separation device with adjustable magnetic field strength for magnetic separation of high titanium slag. Background Technology

[0002] High-titanium slag is an important raw material for the titanium industry. It contains magnetic minerals such as ilmenite and gangue minerals, requiring magnetic separation for purification. Magnetic field strength is a key factor influencing the separation process; a suitable magnetic field strength can effectively capture weakly magnetic minerals like ilmenite while reducing gangue adsorption. In the practice of high-titanium slag magnetic separation, it is necessary to consider the slag grade, mineral particle size distribution, and other characteristics, and rationally adjust the magnetic field strength to achieve efficient separation of magnetic minerals and non-magnetic impurities, providing high-quality raw materials for subsequent titanium product processing.

[0003] Utility model patent CN217512050U discloses a high-efficiency magnetic separator for iron ore. This high-efficiency magnetic separator for iron ore includes two opposing support plates, with a conveying device positioned between the two support plates. The conveying device includes a conveying roller rotatably connected to the rear end plates of the two support plates and a magnetic roller rotatably connected to the front end plates of the two support plates. The conveying roller and the magnetic roller are connected end-to-end by a conveyor belt. A drive motor is coaxially mounted at the end of the conveying roller. A magnetic block is also fixedly installed between the two support plates, located on one side of the magnetic roller and between the upper and lower sections of the conveyor belt. This high-efficiency magnetic separator for iron ore facilitates magnetic separation operations, is easy to use, and provides convenience to users.

[0004] The magnetic separator for this high-efficiency iron ore has a fixed magnetic roller and a fixed magnetic block structure, which cannot change the relative position of the magnetic block and the conveyor belt. It cannot adjust the magnetic field strength according to the difference in the magnetic properties of the raw materials. When facing weakly magnetic raw materials, it is prone to insufficient adsorption. In view of this, we propose a separation device with adjustable magnetic field strength for magnetic separation of high titanium slag. Utility Model Content

[0005] The purpose of this invention is to provide a separation device with adjustable magnetic field strength for magnetic separation of high titanium slag, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A magnetic separation device with adjustable magnetic field strength for high-titanium slag magnetic separation includes a conveyor. A magnetic separation device is installed at an incline above the conveyor. The magnetic separation device includes a frame, a conveyor belt sleeved on the outside of the frame, and a fixed frame installed in the middle of the frame. Rollers are rotatably connected to both ends of the frame. The conveyor belt is sleeved on the outside of two rollers. A rotating motor is coaxially connected to one of the rollers. A magnetic base is sleeved inside the fixed frame. Several permanent magnet blocks are embedded in a rectangular array on the bottom surface of the magnetic base. The bottom surface of the magnetic base faces the inner surface of the bottom belt of the conveyor belt.

[0008] A top plate is bolted to the top of the fixed frame. An adjustment assembly is provided between the top plate and the magnetic base. The adjustment assembly is used to adjust the position of the magnetic base inside the fixed frame. The adjustment assembly includes a guide rail installed on the bottom surface of the top plate, a stop block installed on the top of the magnetic base, and a rotating shaft that runs horizontally through the top of the fixed frame and is rotatably connected to the fixed frame.

The two movable blocks are threaded to the left and right sides of the bidirectional lead screw, respectively. Hinges are hinged between the top of the two movable blocks and the stop block. A first bevel gear is coaxially connected to the end of the bidirectional lead screw, and a second bevel gear is coaxially connected to the rotating shaft. The first bevel gear and the second bevel gear mesh with each other.

[0009] Preferably, a cavity is provided at the middle position of the frame, and a fixed frame is fitted inside the cavity and fixedly connected to the frame;

[0010] In this configuration, the cavity provides installation space for the fixed frame, and the fixed connection prevents the fixed frame from shifting during equipment operation, ensuring the stability of the magnetic field position.

[0011] Preferably, support legs are provided at the four corners of the bottom of the frame, the bottom belt of the conveyor belt moves toward the scraper, and a hopper and a scraper are fixed between the two support legs at the front end of the frame.

[0012] In this setup, the support legs can stably support the magnetic separator, the scraper can scrape off the magnetic minerals on the conveyor belt, and the hopper can catch the scraped-off minerals to prevent them from scattering.

[0013] Preferably, the fixing frame is a cuboid structure with open top and bottom. A magnetic yoke plate is installed at the bottom of the fixing frame by bolts. The top surface of the top plate is in contact with the inner surface of the top belt of the conveyor belt, and the bottom surface of the magnetic yoke plate is in contact with the inner surface of the bottom belt of the conveyor belt.

[0014] In this setup, the open top and bottom structure allows the magnetic base to move up and down to adjust the magnetic field, the bolt installation facilitates the disassembly and maintenance of the top plate and magnetic yoke plate, and the close fit design reduces magnetic field leakage and prevents conveyor belt jamming.

[0015] Preferably, vertical guide grooves are provided on the inner walls of both the left and right sides of the fixed sleeve, and protrusions are provided on the end faces of both the left and right ends of the magnetic base.

[0017] Preferably, the threads on the bidirectional lead screw are symmetrically distributed in the guide rail, and the two movable blocks are symmetrically distributed on the left and right sides of the bidirectional lead screw.

[0018] Of these three settings, the guide groove and the boss can restrict the magnetic seat to move only in the vertical direction, thus avoiding uneven magnetic field; the T-shaped groove and the T-shaped movable block can prevent the movable block from falling off, and the end seat can limit the movable block; the symmetrical thread and the symmetrical movable block can make the abutment block bear force evenly, thus preventing the magnetic seat from tilting.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0033] Please see Figures 1-5 A magnetic separation device with adjustable magnetic field strength for high-titanium slag magnetic separation includes a conveyor 100. A magnetic separation device 200 is inclinedly mounted above the conveyor 100. The magnetic separation device 200 includes a frame 210, a conveyor belt 220 sleeved on the outside of the frame 210, and a fixed frame 230 installed in the middle of the frame 210. Rollers 212 are rotatably connected to both ends of the frame 210. The conveyor belt 220 is sleeved on the outside of the two rollers 212. The support and rotation of the two rollers 212 drive the conveyor belt 220 to operate stably, providing a carrier for the conveying and magnetic separation of the high-titanium slag. One of the rollers 212... A rotating motor 213 is coaxially connected to the conveyor belt 220. The rotating motor 213 provides power to drive the drum 212 to rotate, thereby driving the conveyor belt 220 to achieve cyclic movement and ensure continuous conveying of high-titanium slag. A magnetic base 233 is installed inside the fixed frame 230. The bottom surface of the magnetic base 233 is embedded with several permanent magnet blocks in a rectangular array. The rectangular array of permanent magnet blocks can form a uniform magnetic field area, which improves the adsorption stability of weakly magnetic minerals in the high-titanium slag. The bottom surface of the magnetic base 233 faces the inner surface of the bottom belt of the conveyor belt 220, so that the magnetic field generated by the permanent magnet blocks can directly act on the high-titanium slag on the conveyor belt 220, ensuring the efficiency of the magnetic field action.

[0034] like Figures 1-3As shown, in this utility model, a cavity 211 is provided in the middle of the frame 210, and a fixed frame 230 is fitted in the cavity 211 and fixedly connected to the frame 210. The cavity 211 provides installation space for the fixed frame 230, and the fixed connection method can ensure that the fixed frame 230 does not shift during the operation of the equipment, thus ensuring the stability of the magnetic field position. Support legs are provided at the four corners of the bottom of the frame 210. The support legs can provide stable support for the entire magnetic separator 200 and prevent the equipment from tipping over due to vibration during operation. The bottom belt of the conveyor belt 220 moves towards the scraper 215. The hopper 214 and the scraper 215 are fixed between the two support legs at the head of the frame 210. The scraper 215 is located above the hopper 214, and the top of the scraper 215 is in contact with the outer surface of the bottom belt of the conveyor belt 220. The scraper 215 can scrape off the magnetic minerals adsorbed on the conveyor belt 220. The hopper 214 receives the scraped magnetic minerals, realizing the collection of magnetic minerals and preventing minerals from scattering.

[0035] like Figures 2-4 As shown, specifically, the fixed frame 230 has a cuboid structure with open top and bottom. This open structure ensures that the magnetic base 233 can move up and down within the fixed frame 230, providing space for adjusting the magnetic field strength. The bottom of the fixed frame 230 is bolted with a magnetic yoke plate 232, and the top of the fixed frame 230 is bolted with a top plate 231. The bolt installation method facilitates the subsequent disassembly and maintenance of the top plate 231 and the magnetic yoke plate 232. The top surface of the top plate 231 is in contact with the inner surface of the top belt of the conveyor belt 220, and the bottom surface of the magnetic yoke plate 232 is in contact with the inner surface of the bottom belt of the conveyor belt 220. This contact design reduces the leakage of the magnetic field to the outside and prevents the conveyor belt 220 from getting stuck with the top plate 231 and the magnetic yoke plate 232 during operation, ensuring the smooth movement of the conveyor belt 220.

[0036] like Figure 4 As shown, vertical guide grooves 234 are provided on the inner walls of both the left and right sides of the fixed sleeve 230. Protrusions 2331 are provided at both ends of the magnetic base 233. The two protrusions 2331 extend into the two guide grooves 234 and slide in connection with the fixed sleeve 230. The cooperation between the protrusions 2331 and the guide grooves 234 restricts the movement direction of the magnetic base 233, ensuring that the magnetic base 233 moves only in the vertical direction, thus preventing the magnetic base 233 from shifting and causing uneven magnetic field.

[0037] In order to adjust the magnetic attraction strength of the magnetic separator 200, such as Figures 1-3 and Figure 5As shown, in this embodiment, an adjustment component 300 is provided between the top plate 231 and the magnetic base 233. The adjustment component 300 is used to adjust the position of the magnetic base 233 inside the fixed frame 230. By changing the position of the magnetic base 233, the distance between the permanent magnet block and the conveyor belt 220 can be adjusted, thereby realizing the adjustment of the magnetic field strength. The adjustment component 300 includes a guide rail 310 installed on the bottom surface of the top plate 231, a stop block 320 installed on the top of the magnetic base 233, and a rotating shaft 330 that runs horizontally through the top of the fixed frame 230 and is rotatably connected to the fixed frame 230. The guide rail 310 provides a sliding track for the movable block 314. The stop block 320 can transmit the force of the hinge arm 321 to drive the magnetic base 233 to move. The rotating shaft 330 can transmit power to drive the bidirectional lead screw 312 to rotate.

[0038] Specifically, the guide rail 310 has a T-shaped sliding groove in its cross-section, and the movable block 314 has a T-shaped cross-section and is fitted into the sliding groove. The T-shaped structure prevents the movable block 314 from falling out of the guide rail 310, ensuring stable sliding of the movable block 314. Both ends of the guide rail 310 are equipped with end seats 311, which can limit the movable block 314 and prevent it from sliding out of the guide rail 310. Two movable blocks 314 are slidably connected inside the guide rail 310 and rotatably connected to a bidirectional lead screw 312. The two movable blocks 314 are threaded to the left and right sides of the bidirectional lead screw 312, respectively. The bidirectional lead screw 312 is rotatably connected between the two end seats 311. When the bidirectional lead screw 312 rotates, it can drive the two movable blocks 314 to slide synchronously in opposite directions, providing power for the lifting and lowering of the magnetic base 233. The threads on the bidirectional lead screw 312 are symmetrically distributed in the guide rail 310. The two movable blocks 314 are symmetrically distributed on the left and right sides of the bidirectional lead screw 312. The symmetrical distribution design can ensure that the sliding distance of the two movable blocks 314 is consistent, so that the abutment block 320 is subjected to uniform force and avoids the magnetic seat 233 from tilting.

[0039] Furthermore, hinge arms 321 are hinged between the top of the two movable blocks 314 and the top of the abutment block 320. The hinge structure can realize the motion conversion between the sliding of the movable blocks 314 and the lifting of the abutment block 320, converting the horizontal movement of the movable blocks 314 into the vertical movement of the abutment block 320. The end of the bidirectional lead screw 312 is coaxially connected to the first bevel gear 313, and the rotating shaft 330 is coaxially connected to the second bevel gear 331. The first bevel gear 313 and the second bevel gear 331 mesh with each other. The meshing of the bevel gears can change the direction of power transmission, so that the lateral rotation of the rotating shaft 330 is converted into the longitudinal rotation of the bidirectional lead screw 312, which makes it convenient for the operator to control and adjust the equipment from outside the equipment through the handwheel 332.

[0040] In addition, the end of the rotating shaft 330 passes through and extends out of the front end of the fixed sleeve 230. The end of the rotating shaft 330 is coaxially fixedly connected to a handwheel 332. The handwheel 332 provides a force application point for the operator, making it convenient for the operator to manually rotate the rotating shaft 330 to achieve convenient adjustment of the magnetic field strength.

[0041] It is worth noting that the rotating motor 213 involved in this utility model is a conventional technology and will not be described in detail here.

[0042] In this embodiment, the adjustable magnetic field strength separation device for high-titanium slag magnetic separation operates as follows: First, the rotating motor 213 is started, which drives the connected drum 212 to rotate. The drum 212 drives the conveyor belt 220 to circulate, simultaneously conveying the high-titanium slag to be separated onto the conveyor belt 220. Then, based on the magnetic properties of the high-titanium slag, the operator rotates the handwheel 332, which drives the rotating shaft 330 to rotate. The rotating shaft 330, through the meshing of the second bevel gear 331 and the first bevel gear 313, drives the bidirectional lead screw 312 to rotate. The bidirectional lead screw 312 drives two movable blocks 314 to slide in opposite directions along the guide rail 310. Next, the movable block 314 pushes the abutment block 320 up and down through the hinge arm 321. The abutment block 320 drives the magnetic seat 233 to move vertically along the guide groove 234, adjusting the distance between the permanent magnet block on the magnetic seat 233 and the conveyor belt 220 until a suitable magnetic field strength is reached. At this time, the magnetic field generated by the permanent magnet block adsorbs the magnetic minerals in the high titanium slag on the conveyor belt 220. Finally, the conveyor belt 220 transports the belt body with the adsorbed magnetic minerals to the scraper 215. The scraper 215 scrapes the magnetic minerals off the conveyor belt 220. The scraped magnetic minerals fall into the hopper 214 below for collection. Non-magnetic impurities continue to move with the conveyor belt 220 to the end for discharge.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
