Description

Technical Field

[0001] This application relates to the technical field of fine iron powder purification, and more particularly to an iron powder magnetic separation purification device. Background Technology

[0002] Iron powder is an important industrial raw material, widely used in steel, metallurgy, and chemical industries. During the production and use of iron powder, its purity and impurity content are key factors affecting its performance and effectiveness. Therefore, purification treatment is necessary to improve the purity and quality of iron powder and remove impurities.

[0003] Traditional iron powder purification methods mainly include chemical purification and physical purification. Chemical purification separates impurities from iron powder through chemical reactions, but this method often causes environmental pollution and is costly. Physical purification separates impurities from iron powder through physical methods, commonly including magnetic separation, flotation, and gravity separation. Among these, magnetic separation is a highly efficient, environmentally friendly, and low-cost purification method. It involves arranging multiple magnetic rollers above a conveyor belt, using magnetic force to separate ferrous minerals from non-magnetic minerals during transport. During transport, iron powder is adsorbed onto the magnetic rollers when passing through the magnetic field, while non-ferrous mineral particles are not adsorbed, thus achieving the purpose of magnetic separation.

[0004] However, during the conveying process of iron powder, due to the small size of the iron powder particles, some of the iron powder is often covered under impurities. These iron powder particles are difficult to be adsorbed onto the magnetic roller. Furthermore, the influence of a humid environment can also cause impurities to adhere to the iron powder, thus preventing the iron powder from being adsorbed by the magnetic roller, reducing the magnetic separation efficiency, and resulting in poor magnetic separation effect, which in turn reduces the economic benefits of the enterprise. Summary of the Invention

[0025] Embodiments of this application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. Rather, embodiments of this application include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0026] The iron powder magnetic separation and purification equipment according to embodiments of this application will now be described with reference to the accompanying drawings.

[0027] The iron powder magnetic separation purification equipment provided in this application embodiment can be used to purify iron powder, and can avoid the situation of iron powder being pressed and covered. It can also make iron powder and impurities quickly and effectively separate, which not only improves the magnetic separation efficiency and magnetic separation effect, but also increases the economic benefits of enterprises.

[0028] like Figures 1-6 As shown, the iron powder magnetic separation purification equipment of this application embodiment may include a housing 1, a spraying component 2, a heating coil 3, an arc plate 4, a magnetic separation mechanism 5, a scraper 6, and a driving mechanism 7.

[0029] The box body 1 is connected to a hopper 10, and the box body 1 is provided with a first opening 11 and a second opening 12. 。

[0030] It should be noted that the first opening 11 described in this embodiment is opened on the side wall of the box 1, and the second opening 12 is set on the inner bottom wall of the box 1.

[0031] The spraying component 2, heating coil 3, arc plate 4 and magnetic separation mechanism 5 are respectively arranged in the box 1. The spraying component 2 is arranged above the arc plate 4, the heating coil 3 is arranged on the lower surface of the arc plate 4, and the magnetic separation mechanism 5 is arranged on one side of the arc plate 4.

[0032] It should be noted that the arc plate 4 described in this embodiment is made of a thermally conductive material, such as iron, copper, or ceramic. In conjunction with the heating coil 3, the heating coil 3 can heat the air in the chamber 1 and transfer the heat it generates to the arc plate 4. The arc plate 4 then transfers the heat to the iron powder to be purified, heating the iron powder to reduce its viscosity, thus making it easier for the iron powder to separate from the impurities.

[0033] The arc-shaped plate 4 is used to receive the iron powder to be purified. The spraying component 2 is used to gradually spray the iron powder to be purified in batches towards the magnetic separation mechanism 5. The magnetic separation mechanism 5 is used to purify the iron powder to be purified and to convey the purified iron powder towards the scraper 6. One end of the scraper 6 is set in the housing 1 and is attached to the magnetic separation mechanism 5. The other end of the scraper 6 extends obliquely through the first opening 11. The scraper 6 is used to scrape the purified iron powder off the magnetic separation mechanism 5 and discharge it to the outside of the housing 1. The drive mechanism 7 is set on the housing 1 and is connected to the magnetic separation mechanism 5. The drive mechanism 7 is used to drive the magnetic separation mechanism 5 to run.

[0034] Specifically, in the actual iron powder purification process, the relevant personnel first pour the iron powder to be purified into the box 1 through the hopper 10. The poured iron powder is received by the arc-shaped plate 4. Then, the relevant personnel manually control the operation of the throwing component 2 and the drive mechanism 7. The throwing component 2 rotates and throws the iron powder to be purified in batches towards the magnetic separation mechanism 5. The iron powder to be purified is dispersed in the air to avoid being crushed. The iron powder to be purified thrown in the air is adsorbed by the surrounding magnetic separation mechanism 5, while other impurities fall off. Furthermore, during the scattering process, the iron powder to be purified and impurities collide with the magnetic separation mechanism 5, thereby causing the iron powder adhering to the impurities to be purified to be impacted, which can quickly and effectively separate the iron powder from the impurities. In addition, the heating coil 3 transfers heat to the iron powder to be purified, reducing the adhesion between the iron powder and impurities, making it easier for the iron powder adhering to the impurities to be separated when impacted. At the same time, the batch scattering can further improve the magnetic separation effect of the magnetic separation mechanism 5 on the iron powder, which not only improves the magnetic separation efficiency and effect, but also increases the economic benefits of the enterprise.

[0035] In one embodiment of this application, such as Figure 3 , Figure 4 and Figure 5 As shown, the spraying assembly 2 may include a first motor 20, a pipe body 21, a cross collar 22, a first bevel gear rod 23, two bevel gears 24, two threaded sleeves 25, a second bevel gear rod 26, an internal gear ring 27, a gear 28, and a spraying mechanism 29.

[0036] The first motor 20 is mounted on the housing 1, and the output shaft of the first motor 20 passes through the housing 1. The tube 21 is rotatably connected in the housing 1, and the cross collar 22 is fixed in the tube 21 and is fixedly connected to the output shaft of the first motor 20.

[0037] It should be noted that the cross collar 22 described in this embodiment may include a collar and four vertical rods integrally formed, with the four vertical rods arranged around the outer wall of the collar.

[0038] The first bevel gear rod 23 is rotated and connected to the tube body 21 via the first bearing 200. One end of the first bevel gear rod 23 is fixedly connected to the output shaft of the first motor 20, and the other end of the first bevel gear rod 23 is meshed with a bevel gear 24. Two threaded sleeves 25 are rotatably connected to the tube body 21, and the threaded sleeves 25 are threadedly connected to the spraying mechanism 29. The two bevel gears 24 are fixed on the outer wall of the corresponding threaded sleeves 25. The second bevel gear rod 26 is rotatably connected to the tube body 21 via the second bearing 201, and one end of the second bevel gear rod 26 is rotatably connected to the housing 1. The other end of the second bevel gear rod 26 is meshed with another bevel gear 24. The internal gear ring 27 is fixed in the tube body 21, and the gear 28 is fixed on the outer wall of the second bevel gear rod 26, and the internal gear ring 27 is meshed with the gear 28.

[0039] As a possible scenario, in order to facilitate the control of the first motor 20, relevant personnel can connect an external controller to the first motor 20 and use the controller to control the first motor 20. The controller can also be used to read the rotation angle of the first motor 20 to determine the rotation angle of the spreading mechanism 29.

[0040] Specifically, by controlling the first motor 20, the output shaft of the first motor 20 drives the cross collar 22 and the first bevel gear rod 23 to rotate. The cross collar 22 then drives the tube body 21 to rotate. Simultaneously, the rotation of the tube body 21 drives the spraying mechanism 29 to rotate. During the rotation, the spraying mechanism 29 digs up the iron powder to be purified from the arc plate 4 and throws it towards the magnetic separation mechanism 5. During the rotation of the spraying mechanism 29, the first bevel gear rod 23 drives the bevel gear 24 connected to it to rotate. At the same time, when the tube body 21 rotates, it drives the second bevel gear rod 26 to rotate through the internal gear ring 27 and the gear 28. The rotation of the second bevel gear rod 26 drives the bevel gear 24 connected to it to rotate, thereby driving the threaded sleeve 25 to rotate. This drives the spraying mechanism 29 to gradually extend and gradually spray the iron powder to be purified on the arc plate 4, preventing the height of the iron powder to be purified on the arc plate 4 from gradually decreasing as the iron powder is sprayed, which would make it impossible to dig it up.

[0041] To further clarify the above embodiment, in one embodiment of this application, as follows: Figure 4 As shown, the dispensing mechanism 29 may include two symmetrically arranged screws 290 and a dispensing hopper 291.

[0042] Two screws 290 pass through the through holes opened on the tube body 21, and the two screws 290 are threadedly connected to the corresponding threaded sleeves 25. The adjacent ends of the two screws 290 are fixedly connected to the throwing hopper 291, and the throwing hopper 291 is arranged above the arc plate 4.

[0043] Specifically, when the threaded sleeve 25 rotates, it drives the screw 290 to rotate. When the screw 290 moves, it pushes the throwing hopper 291 downward, thereby changing the position of the throwing hopper 291.

[0044] In one embodiment of this application, such as Figure 4 As shown, the magnetic separation mechanism 5 may include a plurality of first permanent magnet rollers 50 and second permanent magnet rollers 51 and a plurality of first sprockets 52.

[0045] The first permanent magnet rollers 50 and the second permanent magnet rollers 51 are respectively rotatably arranged in the housing 1. The first permanent magnet rollers 50 and the second permanent magnet rollers 51 are distributed in a V-shape, and the first permanent magnet rollers 50 are arranged diagonally upward and diagonally downward with the second permanent magnet rollers 51 as the base point.

[0046] It is understandable that the above settings can encapsulate the iron powder scattered in the air, thereby allowing the iron powder to be absorbed from multiple directions. Furthermore, the impurities can collide multiple times during their fall, accelerating the rate at which the iron powder detaches from the impurities.

[0047] The magnetic force of the first permanent magnet roller 50 is less than that of the second permanent magnet roller 51, and the magnetic force of the multiple first permanent magnet rollers 50 extending outward from the second permanent magnet roller 51 gradually decreases. One end of the scraper 6 is in contact with the bottom of the outer wall of the second permanent magnet roller 51.

[0048] It can be understood that, through the above settings, the iron powder on the first permanent magnet roller 50, which is located on the outermost side relative to the second permanent magnet roller 51, is adsorbed and removed by the adjacent first permanent magnet roller 50, while the second permanent magnet roller 51 adsorbs the iron powder on the adjacent first permanent magnet roller 50. In this way, the iron powder is adsorbed and transferred to the second permanent magnet roller 51 step by step. During the rotation of the second permanent magnet roller 51, the scraper 6 scrapes off the iron powder adsorbed on the second permanent magnet roller 51, thereby improving the adsorption capacity of the first permanent magnet roller 50 and the second permanent magnet roller 51.

[0049] Multiple first sprockets 52 are provided on one side of the housing 1 and multiple first sprockets 52 are provided on the other side of the housing 1. The multiple first sprockets 52 on the same side are driven by a chain. The multiple first sprockets 52 are respectively provided on the end of the first permanent magnet roller 50 or the second permanent magnet roller 51.

[0050] In one embodiment of this application, such as Figure 1 , Figure 2 and Figure 4 As shown, the drive mechanism 7 may include two second sprockets 70, a second chain 71, and a second motor 72.

[0051] The second motor 72 is fixed in the housing 1, and the output shaft of the second motor 72 passes through the inner wall of the housing 1. One second sprocket 70 is fixed on the output shaft of the second motor 72, and the other second sprocket 70 is fixed on the end of a first permanent magnet roller 50. The two second sprockets 70 are connected by a second chain 71.

[0052] Specifically, relevant personnel control the second motor 72, the output shaft of the second motor 72 drives the second sprocket 70 to rotate, the rotation of the second sprocket 70, in conjunction with the second chain 71, drives another second sprocket 70 to rotate, thereby driving a first permanent magnet roller 50 to rotate. When the first permanent magnet roller 50 rotates, it drives the first sprocket 52, in conjunction with the first chain, to drive the remaining first sprockets 52 to rotate, thereby driving the remaining first permanent magnet rollers 50 and the second permanent magnet roller 51 to rotate.

[0053] It should be noted that the second permanent magnet roller 51 rotates clockwise, which makes it easier for the scraper 6 to scrape off the iron powder adsorbed on the second permanent magnet roller 51.

[0054] Furthermore, such as Figure 4 and Figure 6As shown, the above-mentioned iron powder magnetic separation purification equipment also includes a blower mechanism 8, which includes a first support plate 80, a blower 81, an air duct 82, and multiple nozzles 83.

[0055] The first support plate 80 is disposed on the inner bottom wall of the box 1 and is arranged near the second opening 12. The top of the first support plate 80 abuts against the lower surface of the arc plate 4.

[0056] It is understandable that by setting the first support plate 80, not only can the blower 81 be supported, but the arc plate 4 can also be supported, thereby improving the stability of the arc plate 4.

[0057] The blower 81 is installed on the outer side wall of the first support plate 80, and the air outlet of the blower 81 passes through the outer side wall of the first support plate 80 and is connected to the air duct 82. The air duct 82 is installed on the inner side wall of the first support plate 80. Multiple nozzles 83 are connected to the air duct 82 respectively, and the multiple nozzles 83 are arranged facing the multiple through holes opened on the outer wall of the heating coil 3.

[0058] In the embodiments of this application, by setting the blower mechanism 8, the iron powder that has been thrown up can be further lifted up, so that it can be separated from the impurities more quickly. The airflow blown out by the blower mechanism 8 is heated into hot air by the heating coil 3, which can further dry the iron powder and improve the detachment speed of the iron powder adsorbed on the impurities. Specifically, the airflow blown out by the blower 81 is sprayed through the air pipe 82 and multiple nozzles 83 onto the through holes opened on the outer wall of the heating coil 3. The airflow is heated through the through holes and then blown onto the iron powder.

[0059] Furthermore, such as Figure 4 As shown, the above-mentioned iron powder magnetic separation and purification equipment may also include a second support plate 13. The second support plate 13 is disposed on the inner bottom wall of the box 1 and is arranged near the second opening 12. The second support plate 13 and the first support plate 80 together form a Y-shaped feeding channel, and the Y-shaped feeding channel is arranged below the magnetic separation mechanism 5.

[0060] It is understood that the Y-shaped feeding channel formed by the second support plate 13 and the first support plate 80 can receive and collect the falling impurities, thus facilitating the centralized collection of the falling impurities.

[0061] In summary, the iron powder magnetic separation and purification equipment of this application embodiment can avoid the situation of iron powder being pressed and covered, and can also quickly and effectively separate iron powder from impurities, which not only improves the magnetic separation efficiency and magnetic separation effect, but also increases the economic benefits of enterprises.
