Abstract
Description
Technical Field
[0001] The embodiments of this disclosure relate to the field of sorting device technology, and more specifically, to a mineral particle sorting device with coarse separation and magnetic separation functions. Background Technology
[0002] Red mud slag is an important solid waste generated during the production of alumina. In addition to valuable aluminum residues, it also contains a large amount of valuable iron components, mostly iron oxide, which has great potential for comprehensive utilization. If it is not recycled and is simply stockpiled, it will not only cause serious environmental pollution but also lead to a waste of a large amount of iron ore resources. Therefore, the comprehensive recycling and utilization of iron oxide components in red mud is becoming an increasingly important research topic and has attracted much attention from industry experts, scholars and enterprises.
[0003] In addition to iron oxide solid particles, red mud slag also contains insoluble solid particles such as silica and quartz. Therefore, traditional filtration methods alone are insufficient to achieve high-purity separation of iron oxide. Currently, the commonly used method for iron oxide extraction is magnetic separation. Iron oxide magnetic separation technology requires various sizes of magnetic separators and water pumps to work together. After the water pumps transport the red mud slag to the magnetic separators, the magnetic field provided by the separators recovers Fe3O4 magnetite and weakly magnetic Fe2O3 hematite from the red mud ore, yielding iron concentrate. However, magnetic separators have low recovery efficiency, and the magnetic separation process places high demands on the equipment, resulting in significant wear and tear and a higher risk of equipment failure. Regular maintenance and component replacement are necessary, leading to high energy costs. Utility Model Content

[0023] According to one aspect, at least one embodiment of this disclosure provides a mineral particle separation device with roughing and magnetic separation functions, the mineral particle separation device with roughing and magnetic separation functions further comprising:
[0024] A support ring is disposed around the periphery of the screen cylinder and inside the first housing. The support ring is coaxially disposed with the screen cylinder and has a gap between it and the first housing. There are multiple support rings, and all the support rings are arranged along the length direction of the screen cylinder.
[0025] A support wheel is rotatably disposed within the first housing. The axial direction of the support wheel is the same as that of the support ring. The outer circumferential surface of the support ring contacts the support wheel. There are support wheels on both sides of the support ring.
[0026] According to one aspect, at least one embodiment of this disclosure provides a mineral particle separation device with coarsening and magnetic separation functions, wherein both ends of the support ring have positioning protrusions, and the support wheel is located between the positioning protrusions at both ends.
[0027] The beneficial effects of the embodiments disclosed herein are as follows: a material discharge chamber exists between the screen cylinder and the first shell. One end of the screen cylinder is connected to the feed inlet, and the other end is connected to the first discharge outlet. The second discharge outlet is also connected to the material discharge chamber. Red mud slag enters the screen cylinder through the feed inlet of the first shell. During the rotation of the screen cylinder, based on the difference in particle size, smaller particles will fall into the material discharge chamber through the screen holes of the screen cylinder and then be discharged through the second discharge outlet, while larger slag particles will be discharged from the first discharge outlet along the screen cylinder. This process initially separates some impurities, completes the coarse separation process, and reduces the burden on subsequent magnetic separation.
[0028] After the roughing process, the slag flows out from the second discharge port and enters the material inlet of the second shell into the material passage between the magnetic separator drum and the second shell. The rotating magnetic separator drum inside the second shell generates a magnetic field. Under the influence of the magnetic field, Fe3O4 magnetite and weakly magnetic Fe2O3 hematite in the red mud ore are adsorbed onto the surface of the magnetic separator drum. As the magnetic separator drum rotates, the adsorbed iron minerals are carried to the vicinity of the concentrate outlet. At this time, the unloading water pipe located above the concentrate outlet sprays water onto the magnetic separator drum. The impact force of the water flow washes the iron minerals adsorbed on the surface of the magnetic separator drum off, causing them to be discharged from the concentrate outlet, becoming iron concentrate. Substances that are not magnetic or have very weak magnetic properties, such as the remaining silica, quartz, and other insoluble solid particles, cannot be adsorbed by the magnetic separator drum and are discharged from the tailings outlet at the bottom of the second shell under the action of gravity, thus achieving effective separation of iron minerals from other impurities.
[0029] This disclosure removes some fine and large impurities through roughing, reducing the amount of impurities entering the magnetic separation stage. This allows the magnetic separation process to more effectively separate iron minerals, significantly improving the purity of the final iron concentrate and enhancing product quality. The roughing stage effectively reduces the number of impurity particles entering the magnetic separator drum, decreasing wear on the equipment, lowering the risk of malfunction, extending equipment lifespan, reducing the frequency of maintenance and parts replacement, and ultimately lowering energy costs.

[0040] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0041] like Figures 1-2 The diagram illustrates a mineral particle separation device with roughing and magnetic separation functions according to an embodiment of this disclosure. It includes a first housing 1, a screen cylinder 2, a second housing 3, a magnetic separator drum 4, and a discharge water pipe 5. One end of the first housing 1 has a feed inlet 6, the other end has a first discharge outlet 7, and the bottom of the first housing 1 has a second discharge outlet 8. The screen cylinder 2 is rotatably disposed within the first housing 1, with a discharge chamber 9 between them. One end of the screen cylinder 2 is connected to the feed inlet 6, the other end is connected to the first discharge outlet 7, and the second discharge outlet 8 is connected to the discharge chamber 9. The second housing 3 is located on one side of the first housing 1. One end of the second shell 3 has a material inlet 10 for communication with the second discharge port 8, the other end of the second shell 3 has a concentrate outlet 11, and the bottom of the second shell 3 has a tailings outlet 12; the magnetic separator drum 4 is rotatably installed inside the second shell 3, and a material passage 13 is left between the two; the material inlet 10 is located at one end of the magnetic separator drum 4, and the concentrate outlet 11 is located at the other end of the magnetic separator drum 4; the material inlet 10, the concentrate outlet 11 and the tailings outlet 12 are all connected to the material passage 13; the ore discharge water pipe 5 is installed on the second shell 3 and is located above the concentrate outlet 11, and the outlet of the ore discharge water pipe 5 faces the magnetic separator drum 4.
[0042] For example, such as Figure 1 and Figure 2 As shown, a material discharge chamber 9 exists between the screen cylinder 2 and the first shell 1. One end of the screen cylinder 2 is connected to the feed inlet 6, and the other end is connected to the first discharge outlet 7. The second discharge outlet 8 is also connected to the material discharge chamber 9. Red mud slag enters the screen cylinder 2 through the feed inlet 6 of the first shell 1. During the rotation of the screen cylinder 2, based on the difference in particle size, smaller particles will fall into the material discharge chamber 9 through the screen holes of the screen cylinder 2 and then be discharged through the second discharge outlet 8. Larger slag particles will be discharged from the first discharge outlet 7 along the screen cylinder 2, thus initially separating some impurities and completing the coarse separation process, reducing the burden on subsequent magnetic separation.
[0043] After the roughing process, the slag flows out from the second discharge port 8 and enters the material inlet 10 of the second shell 3 into the material passage 13 between the magnetic separator drum 4 and the second shell 3. The rotating magnetic separator drum 4 inside the second shell 3 generates a magnetic field. Under the influence of the magnetic field, Fe3O4 magnetite and weakly magnetic Fe2O3 hematite in the red mud ore are adsorbed onto the surface of the magnetic separator drum 4. As the magnetic separator drum 4 rotates, the adsorbed iron minerals are carried to the vicinity of the concentrate outlet 11. At this time, the unloading water pipe 5 located above the concentrate outlet 11 sprays water onto the magnetic separator drum 4. The impact force of the water flow washes the iron minerals adsorbed on the surface of the magnetic separator drum 4 off, causing them to be discharged from the concentrate outlet 11, becoming iron concentrate. Substances that are not magnetic or have very weak magnetic properties, such as the remaining silica, quartz, and other insoluble solid particles, cannot be adsorbed by the magnetic separator drum 4 and are discharged from the tailings outlet 12 at the bottom of the second shell 3 under the action of gravity, thus achieving effective separation of iron minerals from other impurities.
[0044] This disclosure removes some fine and large impurities through roughing, reducing the amount of impurities entering the magnetic separation stage. This allows the magnetic separation process to more effectively separate iron minerals, significantly improving the purity of the final iron concentrate and enhancing product quality. The roughing stage effectively reduces the number of impurity particles entering the magnetic separator drum 4, decreasing wear on the equipment, lowering the risk of equipment failure, extending equipment lifespan, reducing the frequency of maintenance and parts replacement, and ultimately lowering energy costs.
[0045] In some examples, the screen cylinder 2 is inclined, and the end with the first discharge port 7 is inclined downward.
[0046] For example, such as Figure 1 As shown, after the screen cylinder 2 is tilted, larger slag particles can be discharged more smoothly from the first discharge port 7, which can improve the coarse separation efficiency and make the separation effect of coarse and fine particles better.
[0047] In some examples, a mineral particle separation device with roughing and magnetic separation functions further includes a buffer tank 14, a feed tank 15, and a conveying pump 16. The buffer tank 14 is located between the first housing 1 and the second housing 3, and the second discharge port 8 is connected to the buffer tank 14. The feed tank 15 is disposed on the second housing 3 and is located outside the material inlet 10, which is connected to the feed tank 15. One end of the conveying pump 16 is connected to the buffer tank 14, and the other end of the conveying pump 16 is connected to the feed tank 15.
[0048] For example, such as Figure 1 As shown, the slag after roughing first enters the buffer tank 14 for temporary storage. The conveying pump 16 transports the slag in the buffer tank 14 to the feed tank 15. The feed tank 15 then evenly feeds the slag into the material inlet 10 of the second shell 3. This ensures that the slag flow rate entering the magnetic separation stage is stable and avoids affecting the magnetic separation effect due to fluctuations in the slag flow rate.
[0049] In some examples, the buffer tank 14 is located below the feed tank 15, the buffer tank 14 overlaps with the feed tank 15, and the delivery pump 16 is located on top of the buffer tank 14 and outside the feed tank 15.
[0050] For example, such as Figure 1 As shown, the buffer box 14 can support and position the feed box 15, which can reduce the requirements for the connection strength between the feed box 15 and the second housing 3 and improve stability.
[0051] In some examples, a mineral particle separation device with coarsening and magnetic separation functions also includes a receiving box 17, which is located at the bottom of the second housing 3 and around the tailings outlet 12.
[0052] For example, such as Figure 1 and Figure 2 As shown, after the tailings are discharged from the tailings outlet 12 at the bottom of the second shell 3, they fall directly into the receiving box 17. The receiving box 17 serves to collect the tailings, facilitating centralized treatment of the tailings and preventing them from scattering and impacting the surrounding environment.
[0053] In some examples, a mineral particle separation device with roughing and magnetic separation functions also includes a water receiving box 18, which is disposed on the second housing 3 and located outside the unloading water pipe 5. The side of the water receiving box 18 facing the magnetic separation drum 4 has a water outlet 19, which is located above the unloading water pipe 5.
[0054] For example, such as Figure 3 As shown, the water sprayed from the unloading water pipe 5 falls into the water receiving box 18. When the liquid level in the water receiving box 18 reaches the outlet 19, the water in the water receiving box 18 flows out through the outlet 19 and falls onto the magnetic separation drum 4. The impact force of the water flow washes off the iron minerals adsorbed on the surface of the magnetic separation drum 4, causing them to be discharged from the concentrate outlet 11. The water sprayed from the unloading water pipe 5 does not directly act on the magnetic separation drum 4, which reduces the impact force on the magnetic separation drum 4 while meeting the unloading requirements.
[0055] In some examples, a mineral particle separation device with roughing and magnetic separation functions also includes a guide plate 20 and a baffle 21. The guide plate 20 is located outside the lower end face of the outlet 19, one end of the guide plate 20 is connected to the water receiving box 18, and the other end of the guide plate 20 is inclined downward. The baffle 21 is connected between the end of the guide plate 20 and the water receiving box 18, and the upper end face of the baffle 21 is located above the top surface of the guide plate 20.
[0056] For example, such as Figure 3As shown, the guide plate 20 is inclined, allowing the water flowing from the outlet 19 to flow downwards along the guide plate 20 under the action of gravity, thus guiding the direction of the water flow. The baffle 21 prevents water from splashing out during the outflow process, ensuring that the water can flow smoothly along the guide plate 20, avoiding water splashing and spillage, reducing the impact of water splashing on the working environment and equipment, and improving the stability and reliability of equipment operation.
[0057] In some examples, a mineral particle separation device with coarsening and magnetic separation functions also includes a protective cover 22, which is disposed inside the water receiving box 18 and located between the ore discharge water pipe 5 and the water outlet 19. There are flow passages between the protective cover 22 and the ore discharge water pipe 5 and between the protective cover 22 and the water receiving box 18.
[0058] For example, such as Figure 3 As shown, the protective cover 22 can prevent the water sprayed from the ore unloading water pipe 5 from directly impacting the outlet 19, so that the water flow first passes through the buffer and dispersion of the protective cover 22, and then flows to the outlet 19 through the flow channel. This can avoid the water flow from concentrating and impacting the outlet 19, resulting in poor drainage or water splashing.
[0059] In some examples, a mineral particle separation device with roughing and magnetic separation functions further includes a support ring 23 and a support wheel 24. The support ring 23 is disposed around the screen cylinder 2 and inside the first housing 1. The support ring 23 is coaxially disposed with the screen cylinder 2 and has a gap between it and the first housing 1. There are multiple support rings 23, and all the support rings 23 are arranged along the length direction of the screen cylinder 2. The support wheel 24 is rotatably disposed inside the first housing 1. The axial direction of the support wheel 24 is the same as the axial direction of the support ring 23. The outer circumferential surface of the support ring 23 contacts the support wheel 24. There are support wheels 24 on both sides of the support ring 23.
[0060] For example, such as Figure 1 As shown, multiple support rings 23 are arranged along the length of the screen cylinder 2. The support rings 23 and the support wheels 24 located on both sides work together to share the weight of the screen cylinder 2 and provide reliable support for the screen cylinder 2. When the screen cylinder 2 rotates, the support wheels 24 can rotate accordingly, which can prevent the support rings 23 and the screen cylinder 2 from directly contacting the first housing 1, reduce the resistance encountered by the screen cylinder 2 during rotation, and make the rotation of the screen cylinder 2 more stable.
[0061] In some examples, the support ring 23 has positioning protrusions 25 at both ends, and the support wheel 24 is located between the positioning protrusions 25 at both ends.
[0062] For example, such as Figure 1As shown, the positioning convex ring 25 can position the support wheel 24, prevent the support wheel 24 from axially displacing during the rotation of the screen cylinder 2, ensure that the support wheel 24 always maintains good contact with the support ring 23, stably support the screen cylinder 2, and enhance the stability of the screen cylinder 2 during rotation.
[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
