Description

A device for recovering magnetic iron from iron-containing tailings in copper smelting slag flotation. Technical Field

[0001] This invention relates to the field of tailings treatment technology, specifically to a device for recovering magnetic iron from iron-containing tailings obtained by flotation of copper smelting slag. Background Technology

[0002] Iron tailings are waste products after ore beneficiation and a major component of industrial solid waste. According to incomplete statistics, the world discharges over 10 billion tons of tailings and waste rock annually. If iron tailings could be comprehensively recycled and utilized, it would undoubtedly alleviate the current tension between iron ore supply and demand.

[0003] The existing equipment has the following disadvantages: When the current equipment uses magnetic separators to recover iron-containing substances from tailings, it usually uses a conveyor belt in conjunction with an electromagnet to adsorb the iron-containing substances in the tailings. However, after the tailings are absorbed by the conveyor belt, a small amount of iron-containing substances will remain in the processed material, so multiple recovery processes are required.

[0004] Therefore, this application proposes a magnetic iron recovery device for enriching copper smelting slag flotation iron-containing tailings to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a magnetic iron recovery device for iron-containing tailings from copper smelting slag flotation, in order to solve the problem that a small amount of iron-containing substances remain in the material after the above-mentioned treatment, so multiple recovery treatments are required.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a magnetic iron recovery device for iron-containing tailings from copper smelting slag flotation, comprising a conveying unit for transporting the tailings raw material and an absorption unit disposed above the conveying unit for recovering iron-containing substances from the tailings raw material, and further comprising:

[0007] A collection unit is located on one side of the conveying unit and is used to collect the processed tailings residue.

[0008] A cleaning unit is located on the side of the conveying unit near the collecting unit and connected to the collecting unit, and is used to perform secondary recovery of iron-containing substances in the treated tailings residue.

[0009] The collection unit includes a collection box located on one side of the conveying unit, an adjustment device located inside the collection box for supporting tailings residue, and a lifting lug located on the adjustment device. A traction rope is provided on the lifting lug, and the side of the traction rope away from the lifting lug is connected to the cleaning unit.

[0010] The collection box has a door hinged to the side away from the conveying unit, and a hydraulic cylinder for controlling the opening and closing of the door is provided on the collection box. The power output end of the hydraulic cylinder is connected to the door.

[0011] The collection box is equipped with a guide ring for guiding the traction rope, and a guide wheel for restricting the traction rope is provided on the side of the collection box near the conveying unit.

[0012] The adjusting device includes a guide rod disposed inside the collection box and a support plate passing through the guide rod. A first elastic element is sleeved between the collection box and the support plate on the guide rod, and the lifting lugs are disposed on both sides of the upper end of the support plate.

[0013] The cleaning unit includes a fixed plate adjustablely mounted on the conveying unit, a second electromagnetic plate mounted on the fixed plate, an adjusting block mounted on the fixed plate with its bottom end connected to the traction rope, and a support member mounted on the side of the fixed plate near the collection box. A limit block is provided on the side of the adjusting block near the fixed plate. The limit block slides through the fixed plate. The fixed plate has a limit groove at the position corresponding to the limit block for the limit block to move. A fourth elastic member is provided at the bottom end of the limit block in the limit groove.

[0014] The distance between the upper part of the adjusting block and the collection box gradually decreases.

[0015] The support includes a mounting rod on the side of the fixed plate near the collection box, a collection plate passing through the mounting rod, a connecting plate on the side of the mounting rod away from the fixed plate, a third elastic element sleeved between the mounting rod and the connecting plate, an adjusting block adjustablely disposed between the second electromagnetic plate and the collection plate, and a collection frame for collecting iron-containing substances disposed below the collection plate.

[0016] The conveying unit includes a mounting frame, a first motor disposed on the side of the mounting frame away from the collection box, a first guide roller rotatably disposed inside the mounting frame and connected to the first motor, and a conveyor belt disposed inside the mounting frame and sleeved on the first guide roller. A feed box is disposed on the side of the mounting frame near the first motor.

[0017] The absorption unit includes a fixed frame disposed above the mounting frame, a support frame fixedly disposed on the fixed frame, a second motor disposed on one side of the support frame, a transmission component disposed on the power output end of the second motor, a second guide roller rotatably disposed on the support frame and connected to the transmission component, and a transmission belt disposed on the support frame and sleeved on the second guide roller. A first electromagnetic plate is disposed on the support frame between the transmission belts, and a storage box for collecting iron-containing substances is disposed on the side of the fixed frame away from the second motor.

[0018] The fixed plate has a slider on its end face near the mounting frame. The slider is slidably disposed inside the mounting frame. The mounting frame has a groove for the slider to slide at the position corresponding to the slider. A second elastic element is provided at the lower end of the slider in the groove.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention involves adding the iron tailings material to be recycled to a conveying unit, which then transports it to the lower part of the absorption unit. The absorption unit uses a magnetic attraction device to absorb the iron-containing substances in the tailings. When the tailings fall into the collection unit, they are again absorbed by the magnetic attraction device on the cleaning unit, allowing for secondary collection of the iron-containing substances. Furthermore, as the tailings residue continuously falls into the collection unit, it moves the internal devices, which in turn move the components on the cleaning unit, cleaning and collecting the iron-containing substances adsorbed on it. By using this device, the iron-containing substances in the tailings can be collected and processed multiple times, improving the recovery efficiency.

[0021] 2. In this invention, the traction rope pulls the adjusting block downward, causing the limiting block to move downward inside the limiting groove. Under the pull of the traction rope, the adjusting block enters between the collecting plate and the second electromagnetic plate. The adjusting block pushes the collecting plate to move towards the side of the connecting plate. The collecting plate squeezes the third elastic element, and the distance between the collecting plate and the second electromagnetic plate gradually increases, so that the magnetic force on the iron-containing material magnetically attracted to the collecting plate gradually decreases. Then, the iron-containing material falls into the inside of the collecting frame under the action of gravity. When the traction rope performs a reset movement under the pull of the support plate, the fourth elastic element drives the limiting block to move upward inside the limiting groove, thereby causing the adjusting block seat to reset.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please refer to Figures 1-15. This invention provides a technical solution: a magnetic iron recovery device for iron-containing tailings from copper smelting slag flotation, comprising a conveying unit 1 for transporting the tailings raw material and an absorption unit 2 disposed above the conveying unit 1 for recovering iron-containing substances from the tailings raw material, and further comprising:

[0040] Collection unit 4 is located on one side of conveying unit 1 and is used to collect the processed tailings residue.

[0041] The cleaning unit 5 is located on the side of the conveying unit 1 near the collection unit 4 and is connected to the collection unit 4. It is used to perform secondary recovery of iron-containing substances in the treated tailings residue.

[0042] It should be noted that during operation, the iron tailings raw material to be recycled is added to the conveying unit 1, and then conveyed by the conveying unit 1 to the lower part of the absorption unit 2. The magnetic attraction device on the absorption unit 2 absorbs the iron-containing substances in the iron tailings. When the iron tailings waste falls into the collection unit 4, it will be absorbed again by the magnetic attraction device on the cleaning unit 5, which can collect the iron-containing substances in the iron tailings a second time. As the residue in the iron tailings continues to fall into the collection unit 4, it will drive the device inside the collection unit 4 to move, which in turn drives the components on the cleaning unit 5 to move, cleaning and collecting the iron-containing substances adsorbed on the cleaning unit 5. By setting up this device, the iron-containing substances in the iron tailings can be collected and processed multiple times, improving the recovery efficiency of the iron-containing substances in the iron tailings.

[0043] In one embodiment, the collection unit 4 includes a collection box 41 disposed on one side of the conveying unit 1, an adjustment device 45 disposed inside the collection box 41 for supporting the tailings residue, and a lifting lug 44 disposed on the adjustment device 45. A traction rope 46 is disposed on the lifting lug 44, and the side of the traction rope 46 away from the lifting lug 44 is connected to the cleaning unit 5.

[0044] With this design, the iron tailings residue falls into the collection box 41, causing the adjusting device 45 to move down inside the collection box 41. Then, the traction rope 46 is pulled down inside the collection box 41, causing the other side of the traction rope 46 to move the cleaning unit 5, cleaning the iron-containing substances absorbed on the cleaning unit 5.

[0045] In one embodiment, a door 42 is hinged to the side of the collection box 41 away from the conveying unit 1, and a hydraulic cylinder 43 is provided on the collection box 41 for controlling the opening and closing of the door 42. The power output end of the hydraulic cylinder 43 is connected to the door 42.

[0046] With this design, when the adjusting device 45 moves to the lower end of the collection box 41, it will open the control switch at the bottom of the collection box 41. At this time, the conveying unit 1 is closed and stops transporting iron tailings raw materials. The control switch will start the hydraulic cylinder 43, which will drive the box door 42 to rotate and open, discharging the iron tailings waste inside the collection box 41. After all the iron tailings waste inside the collection box 41 has been discharged, the hydraulic cylinder 43 will drive the box door 42 to close, and then the conveying unit 1 will open to continue transporting iron tailings raw materials.

[0047] In one embodiment, a guide ring 47 is provided on the collection box 41 to guide the traction rope 46, and a guide wheel 48 for restricting the traction rope 46 is provided on the side of the collection box 41 close to the conveying unit 1.

[0048] With this design, the guide ring 47 can restrict the direction of movement of the traction rope 46, the guide wheel 48 can reduce the friction force on the traction rope 46 when it moves, and the traction rope 46 can drive the components on the cleaning unit 5 to move under the drive of the adjusting device 45, so as to clean the absorbed iron-containing substances.

[0049] In one embodiment, the adjusting device 45 includes a guide rod 452 disposed inside the collection box 41 and a support plate 451 passing through the guide rod 452. The guide rod 452 is located between the collection box 41 and the support plate 451 and a first elastic element 453 is sleeved thereon. The lifting lugs 44 are disposed on both sides of the upper end of the support plate 451. The first elastic element 453 is made of a spring or an elastic pad.

[0050] With this design, the iron tailings waste that has been recycled multiple times falls onto the support plate 451. Then, under the action of gravity, the support plate 451 moves up and down on the guide rod 452, and then squeezes the first elastic element 453. As the iron tailings waste on the support plate 451 decreases, the first elastic element 453 drives the support plate 451 to move upward to perform a reset movement.

[0051] In one embodiment, the cleaning unit 5 includes a fixed plate 51 adjustablely disposed on the conveying unit 1, a second electromagnetic plate 56 disposed on the fixed plate 51, an adjusting block 54 disposed on the fixed plate 51 and connected at its bottom end to the traction rope 46, and a support member 55 disposed on the side of the fixed plate 51 near the collection box 41. A limiting block 541 is provided on the side of the adjusting block 54 near the fixed plate 51. The limiting block 541 slides through the fixed plate 51. A limiting groove 511 for the limiting block 541 to move is provided at the position of the limiting block 541 on the fixed plate 51. A fourth elastic member 542 is provided at the position of the limiting groove 511 at the bottom end of the limiting block 541.

[0052] With this design, the traction rope 46 pulls the adjusting block 54 downward, causing the limiting block 541 to move downward inside the limiting groove 511. Under the drive of the traction rope 46, the adjusting block 54 moves between the second electromagnetic plate 56 and the support member 55, increasing the distance between the support member 55 and the second electromagnetic plate 56. This gradually reduces the magnetic force exerted by the second electromagnetic plate 56 on the iron-containing material on the support member 55. When the adjusting block 54 is fully inserted between the support member 55 and the second electromagnetic plate 56, the magnetic force exerted by the second electromagnetic plate 56 on the iron-containing material adsorbed on the support member 55 is less than the gravity exerted on the iron-containing material. Therefore, under the action of gravity, the iron-containing material falls off the support member 55. When the traction rope 46 performs a reset movement under the pull of the support plate 451, the fourth elastic element 542 drives the limiting block 541 to move upward inside the limiting groove 511, thereby causing the adjusting block 54 to reset.

[0053] In one embodiment, the distance between the upper part of the adjusting block 54 and the collection box 41 gradually decreases.

[0054] With this design, under the pull of the traction rope 46, the adjusting block 54 gradually moves between the support member 55 and the second electromagnetic plate 56, so that the distance between the support member 55 and the second electromagnetic plate 56 gradually increases, thereby making the magnetic force of the second electromagnetic plate 56 on the iron-containing material adsorbed on the support member 55 gradually decrease.

[0055] In one embodiment, the support member 55 includes a mounting rod 551 disposed on the side of the fixed plate 51 near the collection box 41, a collection plate 552 passing through the mounting rod 551, a connecting plate 553 disposed on the side of the mounting rod 551 away from the fixed plate 51, a third elastic member 554 sleeved between the mounting rod 551 and the connecting plate 553, an adjusting block 54 adjustablely disposed between the second electromagnetic plate 56 and the collection plate 552, a collection frame 6 for collecting iron-containing substances disposed below the collection plate 552, and the third elastic member 554 being made of a spring or an elastic pad.

[0056] With this design, the adjusting block 54, pulled by the traction rope 46, enters between the collecting plate 552 and the second electromagnetic plate 56. The adjusting block 54 pushes the collecting plate 552 to move towards the side of the connecting plate 553. The collecting plate 552 squeezes the third elastic member 554, and the distance between the collecting plate 552 and the second electromagnetic plate 56 gradually increases. This causes the magnetic force on the iron-containing material magnetically attracted to the collecting plate 552 to gradually decrease. Then, the iron-containing material falls into the interior of the collecting frame 6 under the action of gravity.

[0057] In one embodiment, the conveying unit 1 includes a mounting frame 16, a first motor 11 disposed on the side of the mounting frame 16 away from the collection box 41, a first guide roller 12 rotatably disposed inside the mounting frame 16 and connected to the first motor 11, and a conveyor belt 13 disposed inside the mounting frame 16 and sleeved on the first guide roller 12. A feed box 14 is disposed on the side of the mounting frame 16 near the first motor 11.

[0058] The absorption unit 2 includes a fixed frame 27 mounted above the mounting frame 16, a support frame 21 fixedly mounted on the fixed frame 27, a second motor 22 mounted on one side of the support frame 21, a transmission component 23 mounted on the power output end of the second motor 22, a second guide roller 24 rotatably mounted on the support frame 21 and connected to the transmission component 23, and a transmission belt 25 mounted on the support frame 21 and sleeved on the second guide roller 24. A first electromagnetic plate 26 is mounted on the support frame 21 between the transmission belts 25. A storage box 3 for collecting iron-containing materials is mounted on the side of the fixed frame 27 away from the second motor 22.

[0059] With this design, the first motor 11 starts, driving the first guide roller 12 to rotate. There are two first guide rollers 12, located at both ends inside the mounting frame 16. The rotation of the first guide roller 12 drives the conveyor belt 13 to rotate, thus conveying the iron tailings material inside the feed box 14. When the material is transported to the area below the first electromagnetic plate 26, it is attracted to the transmission belt 25 by the magnetic force of the first electromagnetic plate 26. Then, the second motor 22 drives the second guide roller 24 to rotate. There are two second guide rollers 24, located inside the support frame 21, supporting the transmission belt 25 between the support frames 21. Driven by the second motor 22, the transmission belt 25 rotates, conveying the iron-containing material. When the iron-containing material on the transmission belt 25 reaches the storage box 3, the magnetic force of the first electromagnetic plate 26 on the iron-containing material is less than the weight of the iron-containing material itself. Therefore, under the action of gravity, the iron-containing material falls off the transmission belt 25 and falls into the storage box 3.

[0060] In one embodiment, a slider 52 is provided on the end face of the fixing plate 51 near the mounting bracket 16. The slider 52 is slidably disposed inside the mounting bracket 16. A groove 15 for sliding the slider 52 is provided at the position of the mounting bracket 16 corresponding to the slider 52. A second elastic element 53 is provided at the position of the groove 15 at the lower end of the slider 52. The second elastic element 53 is made of a spring or an elastic pad.

[0061] With this design, when the collecting plate 552 has a large amount of iron-containing material collected, and the adjusting block 54 cannot adjust the installation position of the collecting plate 552 in time, the fixed plate 51 will move down under the action of gravity, causing the slider 52 to move inside the slide groove 15. The slider 52 squeezes the second elastic element 53. When the slider 52 moves to the lowest point, it will open the control element inside the slide groove 15, causing the second electromagnetic plate 56 to be demagnetized, thereby causing the iron-containing material on the collecting plate 552 to fall off. Then the second elastic element 53 drives the slider 52 to move up to perform a reset movement.

[0062] Furthermore, if the embodiments involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relation to the specification. The significance or implied number of the indicated technical features is not specified. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
