Description

Technical Field

[0001] The present invention relates to the technical field of magnetic separators, in particular to a wet three-roller magnetic separator for mining machinery. Background Art

[0002] The wet three-roll magnetic separator is a device specially used for mineral separation, especially for the magnetic separation of fine-grained minerals during the mineral processing process. The device effectively separates magnetic minerals from non-magnetic minerals through the synergistic effect of magnetic field and mechanical force, thereby improving the grade of the minerals. The three-roll magnetic separator is mainly used for magnetic separation of iron ore, manganese ore, titanium ore and other ores. Its core structure consists of three magnetic rollers with adjustable magnetic field strength. It attracts and separates minerals through magnetic fields of different intensities to achieve efficient separation. In addition, the equipment uses water as a medium to keep the material moist during the magnetic separation process, which not only effectively prevents the generation of static electricity, but also reduces the adhesion between particles, thereby significantly improving the separation efficiency.

[0003] However, the existing three-roller magnetic separator has the following shortcomings:

[0004] In the prior art, the magnetic separator drives the auger to transport the slurry through a motor, a sprocket and a chain. Since there is usually starting resistance inside the motor, such as bearing friction and the resistance of the motor coil, the impact force of the slurry alone is usually difficult to overcome these resistances, and the auger can only produce a weak rotation. This rotation is very limited. Failure to start the motor will affect the normal flow of the slurry, and continuously starting the motor to control the flow of the slurry is costly and has certain limitations. In addition, in the scraping process of the magnetic separator, a scraper is usually used to scrape off or water is used to wash the ore adsorbed on the roller. For ore with high viscosity, these two methods cannot completely remove the ore, and the slurry is easily splashed onto the nozzle, causing blockage and poor cleaning effect. In addition, the magnetic block of the magnetic separator in the prior art is usually an integral structure. Once the magnetic block is damaged or the magnetism is weakened, it needs to be replaced as a whole. At the same time, the magnetic block is only fixed by bolts, which is easy to loosen during long-term use, has poor stability, and is not convenient for replacing the magnetic block.

[0005] Therefore, we proposed a wet three-roll magnetic separator for mining machinery in order to solve the problems raised above. Summary of the Invention

[0006] The purpose of the present invention is to provide a wet three-roll magnetic separator for mining machinery, which realizes a lower-cost slurry flow rate adjustment function. First, the second motor is moved upward for a short distance, and the moving path is limited by the slide groove. At this time, the support block loses the downward force and will be reset to the storage groove under the action of the reset spring, and the moving groove limits the moving trajectory of the support block. Then, the second motor is moved down to the bottom inside the fixed frame, and the insert block on the second motor is inserted into the cross-shaped notch from above. Then, the I-shaped block is moved into the cross-shaped notch, so that the insert block and the I-shaped block form a field-shaped structure arrangement. On the rotating rod, the first threaded rod is then inserted into the mounting hole through the rotating block, thereby completing the limiting connection between the second motor and the rotating rod, so that the second motor can drive the rotating rod to rotate. At the same time, the insert block can also be removed to restore the second motor to its original position. The rotation speed of the rotating rod is manually controlled by the turning handle. When the slurry flows to the rotating rod, the impact force generated by the slurry drop is used to drive the paddle and the rotating rod to rotate easily. The paddle will break up the mineral materials in the slurry to prevent particles from settling or agglomerating. Without affecting the rotation of the rotating rod, the switching between manual and automatic adjustment of the slurry flow rate is realized to solve the problems raised by the above background technology.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention realizes a lower-cost slurry flow rate adjustment function through the arrangement of a rotating rod, a paddle, a rotating handle, a cross-shaped notch, an insert block, an I-shaped block, a mounting hole, a first threaded rod, a rotating block, a fixing frame, a slide groove, a second motor, a receiving groove, a return spring, a support block and a moving groove. First, the second motor is moved upward for a short distance, and the moving path is limited by the slide groove.

When the slurry flows to the rotating rod, the impact force generated by the slurry drop is used to drive the paddle and the rotating rod to rotate easily. The paddle will break up the mineral materials in the slurry to prevent particles from settling or agglomerating. Without affecting the self-rotation of the rotating rod, the switching between manual and automatic adjustment of the slurry flow rate is realized, which reduces the use cost of the magnetic separator and solves the problem in the prior art that the magnetic separator motor affects the rotation of the auger and the continuous startup cost of the motor is high.

[0019] 2. The present invention is provided with a connecting rod, a mounting block, a scraper, a nozzle, a fixing groove, a second threaded rod, a knob, a delivery pipe, a connecting plate, a water pump, a water tank and an L-shaped stopper, which achieves a better cleaning effect. The scraper is first used to scrape the mineral material in the groove of the roller, and the water in the water tank is pumped out by the water pump and transported to the nozzle through the delivery pipe. The nozzle is then aimed at the roller for flushing, and the mineral material that has not touched the roller surface and the residual corners is flushed clean, thereby achieving all-round cleaning of the roller. The mineral material is discharged through the discharge port, ensuring that the roller cleaning and scraping processes are completed simultaneously. Since a certain distance is maintained between the nozzle and the roller, the slurry is not easily splashed onto the nozzle during the water spraying process, and the L-shaped stopper arranged on the nozzle can effectively block the slurry splashed when the scraper contacts the roller, and at the same time has a certain blocking effect on the splashing of slurry generated during water spraying, thereby improving the cleaning effect of the magnetic separator and improving the poor cleaning effect of the magnetic separator in the prior art.

[0020] 3. The present invention is provided with a limit sleeve, a card block, a card slot, an arc groove, an arc block, a cover plate, a through hole, a fixing bolt and a nut, which realizes a more stable replacement method. First, remove the roller and open the roller cover, remove the limit sleeve, then remove the fixing bolt, and then rotate the cover plate to disengage the arc block on one side from the arc groove, so that the rotatable arc block on the other side can also be easily disengaged from the arc groove. Then remove the cover plate and replace the damaged magnetic block group as needed. Align the card block of the replaced magnetic block with the card slot and insert it to realize the replacement of multiple groups of magnetic blocks. Splice, then align the rotatable arc block on one side of the cover with the arc groove and insert it, and rotate the cover so that the arc block on the other side is also embedded in the arc groove. Next, clamp the cover on the connecting frame and fix it with fixing bolts and nuts. The limit design of the arc block can prevent the cover from shaking left and right. Then install the limit sleeve on the fixing rod to complete the replacement of the magnetic block, which simplifies the replacement process of the magnetic block, improves the stability of the magnetic block, and avoids the problem in the existing technology that the magnetic separator magnetic block needs to be replaced as a whole and has poor stability.

The bottom and top of the magnetic separation box 101 are respectively provided with a discharge port 111 and a feed port 112. The diffusion mechanism 2 includes a rotating rod 201, which is rotatably connected to the inner side of the magnetic separation box 101, and a paddle 202 is fixedly installed on the outer surface of the rotating rod 201. A handle 203 is fixedly installed on one end of the outer surface of the rotating rod 201, and a cross-shaped slot is provided on the other end of the outer surface of the rotating rod 201. 204, the inner side of the cross-shaped slot 204 is slidably connected with an insert block 205, the outer surface of the insert block 205 is slidably connected with an I-shaped block 206, a fixed frame 210 is fixedly installed on one side of the outer surface of the support frame 102, a slide groove 211 and a movable groove 216 are provided on the inner side of the fixed frame 210, a second motor 212 is slidably connected on the inner side of the slide groove 211, and the insert block 205 is installed at the output end of the second motor 212, a receiving groove 213 is provided on one side of the outer surface of the magnetic separation box 101, and a return spring 214 is fixedly installed on one end of the inner surface of the receiving groove 213. A support block 215 is fixedly installed at one end of the outer surface of 214, and the insert block 205 and the I-shaped block 206 are combined into a field shape and are mounted on the cross-shaped slot 204. The surfaces of the I-shaped block 206 and the rotating rod 201 are both provided with mounting holes 207, and the inner side of the mounting hole 207 is rotatably connected to the first threaded rod 208, and the top of the first threaded rod 208 is fixedly installed with a rotating block 209. The support block 215 is slidably connected to the inner side of the storage groove 213 and the movable groove 216, and the top of the support block 215 and the inner bottom of the fixing frame 210 are both in contact with the bottom end of the second motor 212.

[0036] The effect achieved by the entire embodiment 1 is: a lower-cost slurry flow rate adjustment function is achieved, first the first motor 103 drives the gear 104 to rotate, and the gear 104 drives the chain 105 to rotate, and then the chain 105 drives another set of gears 104 and the shaft cylinder 106 to rotate, and the shaft cylinder 106 drives the roller 107 to rotate on the surface of the fixed rod 108, while the fixed rod 108 remains stationary, and then the slurry is poured into the magnetic separation box 101 from the feed port 112 at the top, and then the slurry flows to the rotating rod 201, and is driven by the impact force generated by the slurry drop. The paddle 202 and the rotating rod 201 rotate easily, and then the paddle 202 will break up the mineral materials in the slurry to prevent the particles from settling or agglomerating. The impact force generated by the rotation of the paddle 202 drives the slurry to flow to the roller 107. Then, the magnetic mineral materials in the slurry are adsorbed on the roller 107 through the magnetic block 110, and the grooves on the roller 107 enable it to adsorb more mineral materials. The non-magnetic mineral materials are squeezed by the roller 107 and flow to the discharge port 111 at the bottom of the magnetic separation box 101 and discharged to the feed port 112 of the next group of magnetic separation boxes 101. Then the magnetic mineral materials will move to the roller. The non-magnetic area of ​​107 slowly falls off. When the flow rate of the slurry needs to be adjusted, the second motor 212 needs to be moved upward for a short distance, and the moving path is limited by the slide groove 211. At this time, the support block 215 loses its downward force and will be reset to the receiving groove 213 under the action of the return spring 214, while the moving groove 216 limits the moving trajectory of the support block 215. Then, the second motor 212 is moved down to the bottom inside the fixing frame 210, so that the insert block 205 on the second motor 212 is inserted into the cross-shaped notch 204 from above, and then the I-shaped block 206 is moved to the cross-shaped notch 206. 04, the insert block 205 and the I-shaped block 206 form a field-shaped structure and are sleeved on the rotating rod 201. Subsequently, the first threaded rod 208 is inserted into the mounting hole 207 through the rotating block 209, thereby completing the limit connection between the second motor 212 and the rotating rod 201. In this way, the second motor 212 can drive the rotating rod 201 to rotate. At the same time, the insert block 205 can also be removed to restore the second motor 212 to its original position. The speed of the rotating rod 201 is manually controlled by the turning handle 203. Under the premise of not affecting the self-rotation of the rotating rod 201, the switching between manual and automatic adjustment of the slurry flow rate is realized, thereby reducing the use cost of the magnetic separator.

[0037] Example 2, according to Figure 3 、 Figure 8 and Figure 9As shown, the separation mechanism 3 includes a connecting rod 301, which is installed at the top of the magnetic separation box 101, and mounting blocks 302 are installed at both ends of the outer surface of the connecting rod 301. Two sets of mounting blocks 302 are installed on both sides of the outer surface of the magnetic separation box 101. The outer surface of the connecting rod 301 is slidably connected to a scraper 303. The outer surface of the roller 107 is provided with a groove, the position of the groove corresponds to the scraper 303, and a nozzle 304 is installed on the top of the scraper 303. A fixing groove 305 is provided on one side of the outer surface of the connecting rod 301 and the scraper 303. A second threaded rod 306 is rotatably connected to the inner side of the fixed groove 305, and a knob 307 is fixedly installed on one end of the outer surface of the second threaded rod 306. A delivery pipe 308 is installed on one end of the outer surface of the nozzle 304, and a connecting plate 309 is installed on one end of the outer surface of the delivery pipe 308. A water pump 310 is installed on one end of the outer surface of another set of delivery pipes 308, and a water tank 311 is installed on the input end of the water pump 310. The water tank 311 is fixedly installed on one side of the outer surface of the magnetic separation box 101, and an L-shaped stopper 312 is fixedly installed on one side of the outer surface of the nozzle 304.

[0038] The effect achieved by the entire embodiment 2 is as follows: a better cleaning effect is achieved. The scraper 303 is first used to scrape the mineral material in the groove of the roller 107, and the water in the water tank is pumped out by the water pump 310, and the water is transported to the nozzle 304 through the delivery pipe 308, and then the nozzle 304 is aimed at the roller 107 for flushing, and the mineral material that has not touched the surface and corners of the roller 107 is flushed clean, thereby achieving all-round cleaning of the roller 107, and the mineral material is discharged through the discharge port 111, ensuring that the cleaning of the roller 107 and the scraping process are completed simultaneously. Since a certain distance is maintained between the nozzle 304 and the roller 107, the slurry is not easily splashed onto the nozzle 304 during the water spraying process, and the L-shaped block 312 provided on the nozzle 304 can effectively block the slurry splashed when the scraper 303 contacts the roller 107, and at the same time has a certain blocking effect on the splashing of the slurry generated during the water spraying, thereby improving the cleaning effect of the magnetic separator.

A clamping block 402 is fixedly installed on one side of the outer surface of the connecting frame 109, and a clamping groove 403 is opened on the other side of the outer surface of the connecting frame 109. The clamping block 402 is clamped on the inner side of the clamping groove 403. The top of the connecting frame 109 is provided with an arc groove 404, and the inner side of the arc groove 404 is slidably connected with an arc block 405. The arc block 40 5 is installed with a cover plate 406 at the top, and one set of arc blocks 405 is rotatably connected to the bottom end of the cover plate 406, and the cover plate 406 is clamped on the top end of the connecting frame 109. The surfaces of the connecting frame 109, the arc blocks 405 and the cover plate 406 are all provided with through holes 407, and the inner side of the through hole 407 is rotatably connected with a fixing bolt 408, and the bottom end of the fixing bolt 408 is rotatably connected with a nut 409, which is clamped on the bottom end of the arc block 405.

[0040] The effect achieved by the entire embodiment 3 is: a more stable replacement method is achieved, first remove the roller 107 and open the roller cover, remove the limit sleeve 401, then remove the fixing bolt 408, and then rotate the cover plate 406 to disengage the arc block 405 on one side from the arc groove 404, so that the rotatable arc block 405 on the other side can also easily disengage the arc groove 404, then remove the cover plate 406, and replace the damaged magnetic block 110 group as needed, align the card block 402 of the replaced magnetic block 110 with the card slot 403 and insert it to achieve the splicing of multiple groups of magnetic blocks 110, and then remove the cover plate 406. The rotatable arc block 405 on one side is aligned with the arc groove 404 and inserted, and the cover plate 406 is rotated so that the arc block 405 on the other side is also embedded in the arc groove 404. Next, the cover plate 406 is clamped on the connecting frame 109 and fixed by fixing bolts 408 and nuts 409. The limiting design of the arc block 405 can prevent the cover plate 406 from shaking left and right. Then the limiting sleeve 401 is installed on the fixing rod 108 to complete the replacement of the magnetic block 110, which simplifies the replacement process of the magnetic block 110, facilitates the replacement of the magnetic block 110, and improves the stability of the magnetic block 110.

[0041] The working principle of the whole equipment is as follows: when using the magnetic separator, the first motor 103 drives the gear 104 to rotate, and the gear 104 drives the chain 105 to rotate, and then the chain 105 drives another set of gears 104 and the shaft 106 to rotate, and the shaft 106 drives the roller 107 to rotate on the surface of the fixed rod 108, while the fixed rod 108 remains stationary, and then the slurry is poured into the magnetic separation box 101 from the feed port 112 at the top, and then the slurry will flow to the rotating rod 201, and the impact force generated by the drop of the slurry drives the paddle 202 and the rotating rod 201 to rotate easily, and then the paddle 202 will break up the mineral material in the slurry to prevent the particles from settling or agglomerating, and the generated by the rotation of the paddle 202 The impact force generated drives the slurry to flow to the roller 107, and then the magnetic mineral material in the slurry is adsorbed on the roller 107 through the magnetic block 110, and the groove on the roller 107 enables it to adsorb more mineral material, and the non-magnetic mineral material is squeezed by the roller 107 and flows to the discharge port 111 at the bottom of the magnetic separation box 101 and discharged to the feed port 112 of the next group of magnetic separation boxes 101. Then the magnetic mineral material will move to the non-magnetic area of ​​the roller 107 and slowly fall off, and then move to the scraper 303 to scrape off the mineral material on the groove of the roller 107. At the same time, the water in the water tank is extracted by the water pump 310, so that the water moves to the nozzle 304 through the delivery pipe 308, and then the nozzle 304 is aimed at the roller 107 for washing, and the mineral material that has not touched the roller is washed. The residual mineral materials on the drum 107 and the corners are washed off, realizing the all-round cleaning of the roller 107, and the mineral materials are discharged through the discharge port 111, so that the cleaning of the roller 107 and the scraping are completed at the same time. Since the position of the nozzle 304 is a certain distance away from the roller 107, the slurry is not easy to splash onto the nozzle 304 during the water spraying process of the nozzle 304, and the L-shaped stopper 312 provided on the nozzle 304 blocks the slurry splashed when the scraper 303 contacts the roller 107, and at the same time has a certain blocking effect on the slurry splashed when the water is sprayed, thereby improving the cleaning effect of the magnetic separator. Then the slurry will pass through the remaining two groups of magnetic separation boxes 101, thereby separating three mineral materials with different magnetic properties, and different grades can be completed by adjusting the magnetic strength of the magnetic block 110 Magnetic separation of mineral materials. When the scraper 303 needs to be replaced, first remove the mounting block 302 and remove the conveying pipe 308 from the connecting plate 309. Then, disassemble the second threaded rod 306 by turning the knob 307 and remove the scraper 303 from the connecting rod 301. Then, the replacement of the scraper 303 can be completed. When the flow rate of the slurry needs to be adjusted, the second motor 212 needs to be moved up a small distance, and the moving path of the second motor 212 is limited by the slide 211. At this time, the support block 215 loses its downward force and will be moved to the receiving groove 213 by the reset spring 214, and the moving groove 216 limits the moving path of the support block 215. Then, the second motor 212 is moved down to the bottom inside the fixing frame 210.The insert block 205 on the second motor 212 is directly inserted into the cross-shaped slot 204 from above, and then the I-shaped block 206 is moved into the cross-shaped slot 204, so that the insert block 205 and the I-shaped block 206 form a field-shaped sleeve on the rotating rod 201, and then the first threaded rod 208 is inserted into the mounting hole 207 through the rotating block 209, thereby completing the position limitation of the second motor 212 and the rotating rod 201, and then the rotating rod 201 can be driven by the second motor 212 to rotate. The plug block 205 can also be removed to move the second motor 212 back to its original position, and the rotation speed of the rotating rod 201 can be manually controlled by turning the handle 203. Under the premise of not affecting the self-rotation of the rotating rod 201, the manual and automatic adjustment of the slurry flow rate is switched, which reduces the use cost of the magnetic separator. When the magnetic block 110 needs to be replaced, the roller 107 can be removed and the cylinder cover can be opened. Then the limit sleeve 401 can be removed, and then the fixing bolt 408 can be removed. The cover plate 406 can be rotated to make it When the arc block 405 on one side is disengaged from the arc groove 404, the rotatable arc block 405 on the other side can be easily disengaged from the arc groove 404, and the cover plate 406 can be removed. Then, the damaged set of magnetic blocks 110 can be removed and replaced as needed, and then the card block 402 of the replaced magnetic block 110 is aligned with the card slot 403 and inserted to realize the splicing of multiple sets of magnetic blocks 110. Then, the rotatable arc block 405 on one side of the cover plate 406 is aligned with the arc groove 404 and inserted, and then the cover plate 406 is rotated. Insert the arc block 405 on the other side into the arc groove 404, then the cover plate 406 can be clamped onto the connecting frame 109. Then, fix the cover plate 406 with the fixing bolts 408 and nuts 409. The arc block 405 limits the cover plate 406 so that it will not shake left and right. Then install the limiting sleeve 401 on the fixing rod 108. The replacement of the magnetic block 110 is completed, which facilitates the replacement of the magnetic block 110 and improves the stability of the magnetic block 110.
