Description

Technical Field

[0001] This utility model relates to the field of iron powder production technology, and more specifically, to a purification device for iron powder production. Background Technology

[0002] In the iron powder production process, the raw materials often contain a variety of impurities. If these impurities are not effectively removed, they will directly affect the purity, physical properties, and chemical properties of the iron powder, thereby reducing its application value in powder metallurgy, magnetic materials, chemical industry, and other fields. Therefore, impurity removal equipment is a key link in the iron powder production line to ensure product quality. Magnetic separators are commonly used to remove impurities from iron powder raw materials. During operation, the raw material falls evenly onto the surface of the drum from the external feed hopper. Ferromagnetic particles are attracted by the magnetic field and rotate with the drum. When they reach the non-magnetic area, they fall off due to gravity. Non-magnetic impurities, such as quartz and plastic, are discharged directly from the discharge port below, completing the iron powder impurity removal process. Since the impurity removal and feeding of iron powder directly affects the convenience of subsequent processing, it is necessary to implement magnetic separation feeding restriction operations.

[0003] In related technologies, during the use of magnetic separators, the magnetic force of the magnetic drum during operation is generally used to divide the magnetically separated iron powder into zones for magnetic feeding. The iron powder is attracted by the magnetic field of the drum and rotates with the drum. When it reaches the area without magnetic field, it falls off due to gravity, thus completing the magnetic feeding process and making it usable.

[0004] However, during the current use of magnetic separators, due to the inertia of the iron powder following the magnetic attraction of the drum during the demagnetization and feeding process, the iron powder will be thrown backward when it leaves the drum, which can easily cause the iron powder to move out of the feeding range, affecting the feeding stability and feeding effect of the magnetic separator.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1-4 This utility model provides a technical solution: a purification device for iron powder production, including a support 1 and a feeding restriction mechanism. A magnetic separator 2 is installed on the top of the inner side of the support 1, and a motor 3 connected to the magnetic separator 2 is installed on the front side of the top of the support 1. This can form a feeding restriction and stabilizing medium at the feeding position at the bottom of the magnetic separator 2, so that the user can restrict the feeding range of iron powder on the surface of the magnetic separator 2 during magnetic separation and purification when the magnetic separator 2 is working. This prevents the iron powder on the surface of the magnetic separator 2 from moving out of the feeding range due to instability, thus improving the feeding stability and feeding effect of the magnetic separator 2.

[0031] Reference Figures 1-4 In a preferred embodiment, the feeding restriction mechanism includes a restriction plate 4, which is movably connected to the bottom left side of the magnetic separator 2. A restriction opening 5 is provided on the inner side of the restriction plate 4, and a translation plate 6 is movably connected inside the restriction opening 5. Contact strips 7 are fixedly connected to the tops of both the restriction plate 4 and the translation plate 6. A restriction fixing mechanism is movably connected to the outer left side of the restriction plate 4. By cooperating with the restriction opening 5, the restriction plate 4 is installed on the left side of the bottom of the magnetic separator 2, which is the feeding position of the magnetic separator 2, and the top of the contact strips 7 contacts the surface of the magnetic separator 2. When iron powder is fed, the restriction plate 4 cooperates with the translation plate 6... The device blocks and restricts the iron powder during the feeding process to ensure stability. At the same time, the contact strip 7 scrapes and removes the iron powder from the surface of the magnetic separator 2. The limiting and fixing mechanism includes a fixing column 8, a fixing frame 9, and a fixing plate 10. The fixing column 8 is movably connected to the outer side of the left side of the limiting plate 4, the fixing frame 9 is fixedly connected to the left side of the fixing column 8, and the fixing plate 10 is movably connected to the inner side of the fixing frame 9. This mechanism can limit and fix the limiting plate 4 and the bracket 1, so that the user can install and fix the limiting plate 4 and the bracket 1, ensuring the stability of the limiting plate 4 during feeding and thus improving the ease of installation and fixing of the limiting plate 4.

[0032] Reference Figures 2-4 In a preferred embodiment, a screw hole 11 is provided on the left side of the inner side of the fixing post 8. A stud 12 is threaded inside the screw hole 11. The inner side of the stud 12 is connected to the outer side of the fixing plate 10. This provides a medium for the user to apply a clamping force to the fixing plate 10, avoiding the situation where the fixing plate 10 is difficult to clamp during use. Therefore, the ease of applying force to fix the fixing plate 10 is improved. A connecting groove 13 is provided on the outer side of the fixing plate 10. A connecting seat 14 is magnetically connected inside the connecting groove 13. The outer side of the connecting seat 14 is fixedly connected to the inner side of the stud 12. This can perform connection and anti-separation work between the stud 12 and the fixing plate 10, preventing the screw 20 from separating from the fixing plate 10 during use. Therefore, the connection effect between the stud 12 and the fixing plate 10 is improved.

[0033] Reference Figures 2-3 In a preferred embodiment, a sliding opening 15 is provided on the left side of the inner wall of the limiting opening 5. A sliding block 16 is movably connected inside the sliding opening 15. The right side of the sliding block 16 is fixedly connected to the left side of the translation plate 6. This allows for a movable connection and anti-disengagement function between the translation plate 6 and the limiting opening 5, thus improving the translational adjustment stability of the translation plate 6. An adjustment groove 17 is provided on the right side of the fixing post 8. An adjustment post 18 is magnetically connected inside the adjustment groove 17. The right side of the adjustment post 18 is fixedly connected to the left side of the limiting plate 4. This allows for adjustment of the connection between the fixing post 8 and the limiting plate 4, enabling the user to change the position between the limiting plate 4 and the fixing post 8 according to usage requirements, thus improving the flexibility of the limiting plate 4.

[0034] Reference Figures 2-3 In a preferred embodiment, a screw groove 19 is provided on the right side of the top inside the adjusting groove 17. The screw groove 19 is threadedly connected to a screw 20, which can be used by the user to tighten and fix the adjusting column 18 and the fixed column 8. This improves the ease of positioning the adjusting column 18 and the fixed column 8. A movable groove 21 is provided on the top of the adjusting column 18. The bottom of the screw 20 is located inside the movable groove 21, which provides the screw 20 with a force-applying space to adjust the adjusting column 18 and the fixed column 8 and prevent them from disengaging. This improves the flexibility of the screw 20 in use.

[0035] Specifically, the working process or working principle of this impurity removal equipment for iron powder production is as follows: During use, the inner side of the moving support 1 is moved along the limiting plate 4, and the actual material feeding limitation range of the magnetic separator 2 is removed. The limiting plate 4 is then moved to both sides to adjust its feeding limitation range. At this time, the translation plate 6 moves inside the limiting opening 5 to fill the adjustment space between the limiting plates 4. Simultaneously, the slide block 16 follows the translation plate 6 and moves inside the sliding opening 15, ensuring a sliding connection between the translation plate 6 and the limiting plate 4 to prevent detachment, and ensuring the solid... The fixed frame 9 and the fixed plate 10 are located outside the support 1. Then, the holding limiting plate 4, in conjunction with the sliding block 16 and the translation plate 6, moves the contact strip 7 upwards to contact the surface of the magnetic separator 2, preparing for subsequent scraping and feeding of iron powder from the surface of the magnetic separator 2. Next, the holding stud 12 is rotated to engage the screw hole 11, applying an outward threaded force to the fixed plate 10 through the connecting seat 14 and the connecting groove 13. This causes the fixed plate 10, in conjunction with the fixed frame 9, to clamp and fix the limiting plate 4 and the support 1 via the adjusting column 18. Finally, according to the feeding position of the magnetic separator 2... To adjust the position of the limiting plate 4, the hand-held limiting plate 4 moves the translation plate 6. During this adjustment, the adjusting column 18 moves with the limiting plate 4 within the adjusting groove 17, adjusting the connection between the limiting plate 4 and the fixed column 8. Simultaneously, the bottom of the screw 20 moves within the movable groove 21, preventing separation between the adjusting column 18 and the adjusting groove 17. After the positions of the limiting plate 4 and the translation plate 6 are adjusted, the hand-held screw 20 is rotated to engage the screw groove 19, causing the screw 20 to move downwards and contact the bottom of the inner wall of the movable groove 21. The fixed column 8 and the adjusting column 18 are tightened and fixed to keep the position of the limiting plate 4 and the translation plate 6 stable. When the magnetic separator 2 works to remove iron powder from the outside by magnetic attraction, the iron powder moves with the magnetic separator 2 to the bottom of the magnetic separator 2 and is discharged without magnetism. When the iron powder is discharged, the limiting plate 4 and the translation plate 6 work together to block and restrict the iron powder during the discharge process. At the same time, the contact strip 7 scrapes and removes the iron powder that is attached to the surface of the magnetic separator 2 and has not been discharged, so that the iron powder on the surface of the magnetic separator 2 is discharged within a fixed discharge range.

[0036] It should be noted that the support 1, magnetic separator 2 and motor 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
