Description

Technical Field

[0001] This utility model relates to the field of metal powder impurity removal technology, specifically a multi-channel magnetic separation impurity removal device for metal powder. Background Technology

[0002] During the production and processing of metal powders, it is necessary to remove ferromagnetic impurities to improve the purity of the metal powders (such as aluminum, copper, titanium, etc.). Magnetic separation is a device used to separate magnetic impurities from metal powders. The core principle of magnetic separation is to separate them based on magnetic differences. It typically consists of multiple independent magnetic separation channels, which can simultaneously perform magnetic separation on multiple samples or different portions of the same batch, thereby improving separation efficiency.

[0003] Some existing magnetic separation and impurity removal devices use vibration to clean the magnetic materials adsorbed on the surface of permanent magnets. This method can lead to loosening of the permanent magnet fixing structure, bearing wear, and fatigue fracture of transmission components, thus affecting the efficiency of magnetic separation. Utility Model Content

[0004] The purpose of this invention is to provide a multi-channel magnetic separation and impurity removal device for metal powder, so as to solve the problems mentioned in the background art.

[0005] To solve the above problems, this utility model provides the following technical solution: a multi-channel magnetic separation device for removing impurities from metal powder, comprising a frame and an impurity removal section:

[0006] The top of the frame is provided with a feeding trough, the side of the frame is provided with a receiving trough a, and the end of the frame away from the receiving trough a is provided with a receiving trough b. The impurity removal part is located inside the frame. The impurity removal part has a rotating frame that is laterally rotatably arranged inside the frame. Several magnets are embedded on the surface of the rotating frame. Several sliding frames are slidably arranged inside the rotating frame. The sliding frames are arranged in a central rotational symmetry structure around the rotation center of the rotating frame. The sliding frames slide outward away from the magnets to control the strength of the magnetic force on the magnetic powder on the sliding frames.

[0007] By adopting the above technical solution, metal powder can enter the machine frame from the feed trough. During the rotation of the rotating frame, the magnetic force generated by the magnet attracts magnetic impurities in the metal powder. The distance between the sliding frame and the magnet is changed by the sliding of the sliding frame, thereby flexibly controlling the strength of the magnetic force on the magnetic powder, realizing the effective adsorption and separation of impurities with different magnetic intensities. Finally, the pure metal powder falls into the receiving trough a, and the magnetic impurities are moved to the receiving trough b.

[0008] Preferably, the impurity removal unit also has a rotating shaft disposed on the side of the rotating frame. The rotating shaft passes laterally through the frame and is rotatably connected to the frame. A motor is disposed on the side of the frame, and the output end of the motor is connected to the rotating shaft. Several frames are arranged laterally, and several rotating shafts are connected to each other end to end.

[0009] By adopting the above technical solution, the rotating shaft can be driven by a motor to rotate, thereby driving the rotating frame to rotate inside the frame, realizing the function of magnetic separation and impurity removal. Multiple frames are arranged horizontally, and multiple rotating shafts are connected end to end, so that multiple impurity removal units can work synchronously, forming a multi-channel magnetic separation and impurity removal effect, which greatly improves the efficiency and throughput of metal powder impurity removal.

[0010] Preferably, the impurity removal section also has a groove formed on the surface of the rotating frame, and several of the magnets are embedded in the groove.

[0011] By adopting the above technical solution, the magnet can be stably installed on the rotating frame. The groove plays a role in positioning and fixing the magnet, preventing the magnet from shifting or shaking during the rotation of the rotating frame.

[0012] Preferably, the impurity removal section also has a groove formed inside the rotating frame, and a slide rod is provided on the side of the sliding frame, which is embedded in the groove and slidably connected to the rotating frame.

[0013] By adopting the above technical solution, the sliding frame can slide in the groove inside the rotating frame via the sliding rod, providing guidance and support for the movement of the sliding frame.

[0014] Preferably, the impurity removal section also has a transfer groove formed at the end of the sliding frame away from the slide bar, and the edge of the transfer groove is provided with a bevel.

[0015] By adopting the above technical solution, when magnetic impurities need to be transferred during the sliding process of the sliding frame, the transfer groove can collect and guide the magnetic impurities, and the inclined surface of the edge helps the magnetic impurities to slide off the sliding frame or be transferred to the receiving groove a more smoothly.

[0016] Preferably, the impurity removal unit also has a drive shaft disposed on the side of the slide bar, and the inner wall of the frame is provided with a guide groove, the drive shaft being embedded in the guide groove and slidably connected to the frame.

[0017] By adopting the above technical solution, the drive shaft can slide in the guide groove when the rotating frame rotates. The guide groove provides a specific trajectory for the movement of the drive shaft, thereby indirectly controlling the sliding of the slide rod and the sliding frame. This allows the sliding frame to change its distance from the magnet in a preset manner, realizing automated magnetic force adjustment and impurity transfer operations.

[0018] Preferably, the guide groove is an elliptical annular groove with chamfered edges.

[0019] By adopting the above technical solution, when the drive shaft slides in the elliptical guide groove, the distance between the sliding frame and the magnet can be changed periodically as the rotating frame rotates, thereby realizing the periodic adjustment of the magnetic force on the magnetic powder.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: By providing a purification section, metal powder can enter the machine frame from the feed trough. During the rotation of the rotating frame, the magnetic force generated by the magnet adsorbs magnetic impurities in the metal powder. Furthermore, by sliding the sliding frame to change its distance from the magnet, the strength of the magnetic force on the magnetic powder can be flexibly controlled, achieving effective adsorption and separation of impurities with different magnetic intensities. Finally, the pure metal powder falls into the receiving trough a, while the magnetic impurities are moved to the receiving trough b. When the drive shaft slides in the elliptical ring guide groove, the sliding frame can periodically change its distance from the magnet as the rotating frame rotates, achieving periodic adjustment of the magnetic force on the magnetic powder, further optimizing the purification effect.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a multi-channel magnetic separation device for removing impurities from metal powder, comprising a frame 1 and a removal section 2;

[0031] A feed trough 101 is provided on the top of the frame 1. This feed trough 101 is used to receive the metal powder after impurity removal, providing material input for the subsequent impurity removal process. A receiving trough a102 is provided on the side of the frame 1, and a receiving trough b103 is provided at the end away from the receiving trough a102. These two receiving troughs perform different functions. The receiving trough a102 is used to collect the pure metal powder after impurity removal, and the receiving trough b103 is used to collect the magnetic impurities separated from the metal powder. The impurity removal unit 2 is located inside the frame 1. The impurity removal unit 2 has a rotating frame 201 that is laterally rotatably arranged inside the frame 1. Several magnets 205 are embedded on the surface of the rotating frame 201, and the rotating frame 201 is slidably arranged inside. There are several sliding frames 206, which are arranged in a central rotational symmetry around the rotation center of the rotating frame 201. The sliding frames 206 slide outward away from the magnet 205 to control the strength of the magnetic force on the magnetic powder on the sliding frames 206. This allows the metal powder to enter the machine frame 1 from the feed trough 101. During the rotation of the rotating frame 201, the magnetic force generated by the magnet 205 adsorbs magnetic impurities in the metal powder. The sliding frames 206 change their distance from the magnet 205 by sliding, thereby flexibly controlling the strength of the magnetic force on the magnetic powder. This achieves effective adsorption and separation of impurities with different magnetic intensities, and finally allows the pure metal powder to fall into the receiving trough a102, while the magnetic impurities are moved to the receiving trough b103.

[0032] Example 2

[0033] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a multi-channel magnetic separation device for removing impurities from metal powder, comprising a frame 1 and a removal section 2;

[0034] A rotating shaft 202 is provided on the side of the rotating frame 201. The rotating shaft 202 passes laterally through the frame 1 and is rotatably connected to the frame 1. A motor 210 is provided on the side of the frame 1. The output end of the motor 210 is connected to the rotating shaft 202. Several frames 1 are arranged laterally, and several rotating shafts 202 are connected end to end. The working principle of the motor 210 is based on electromagnetic induction and Lorentz force. The motor 210 generates force in the magnetic field through current, thereby driving mechanical movement. The above is the prior art and will not be elaborated further below. When selecting the model, its power should be selected to match the needs of the device to ensure that the object to be driven is driven. The rotating shaft 202 can be driven to rotate by the motor 210, thereby driving the rotating frame 201 to rotate inside the frame 1, realizing the function of magnetic separation and impurity removal. Multiple frames 1 are arranged laterally, and multiple rotating shafts 202 are connected end to end, so that multiple impurity removal units 2 can work synchronously to form a multi-channel magnetic separation and impurity removal effect, which greatly improves the efficiency and throughput of metal powder impurity removal.

[0035] A groove 204 is provided on the surface of the rotating frame 201, and several magnets 205 are embedded in the groove 204. The magnets 205 can be stably installed on the rotating frame 201. The groove 204 plays a role in positioning and fixing the magnets 205, preventing the magnets 205 from shifting or shaking during the rotation of the rotating frame 201.

[0036] A groove 203 is provided inside the rotating frame 201, and a slide rod 208 is provided on the side of the sliding frame 206. The slide rod 208 is embedded in the groove 203 and slidably connected to the rotating frame 201, so that the sliding frame 206 can slide in the groove 203 inside the rotating frame 201 through the slide rod 208, providing guidance and support for the movement of the sliding frame 206.

[0037] A transfer groove 207 is provided at the end of the sliding frame 206 away from the sliding rod 208 for holding materials. The edge of the transfer groove 207 is provided with a slope. When magnetic impurities need to be transferred during the sliding of the sliding frame 206, the transfer groove 207 can collect and guide the magnetic impurities. The slope of the edge helps the magnetic impurities to slide off the sliding frame 206 more smoothly or be transferred to the receiving groove a102.

[0038] A drive shaft 209 is provided on the side of the slide bar 208. A guide groove 104 is provided on the inner wall of the frame 1. The drive shaft 209 is embedded in the guide groove 104 and slidably connected to the frame 1. When the rotating frame 201 rotates, the drive shaft 209 slides in the guide groove 104. The guide groove 104 provides a specific trajectory for the movement of the drive shaft 209, thereby indirectly controlling the sliding of the slide bar 208 and the sliding frame 206. This allows the sliding frame 206 to change its distance from the magnet 205 in a preset manner, realizing automated magnetic force adjustment and impurity transfer operations.

[0039] The guide groove 104 is an elliptical annular groove with a chamfered edge. This allows the drive shaft 209 to slide within the elliptical annular guide groove 104. As the rotating frame 201 rotates, the sliding frame 206 can periodically change its distance from the magnet 205, thereby achieving periodic adjustment of the magnetic force on the magnetic powder.

[0040] Working principle: First, the metal powder to be purified is poured into the feed trough 101 at the top of the frame 1. The metal powder falls from the feed trough 101 into the transfer groove 207 of the sliding frame 206 inside the frame 1 due to its own gravity. Then, the motor 210 is started, driving the rotating shaft 202 to rotate, causing the rotating frame 201 to rotate laterally inside the frame 1. During the rotation of the rotating frame 201, the sliding frame 206, which is slidably embedded on the surface of the rotating frame 201, moves around the rotating shaft 202. Simultaneously, the magnetic force generated by the magnet 205 attracts magnetic impurities. As the rotating frame 201 rotates, the sliding frame 206 gradually tilts, causing the pure metal powder that is not attracted by the magnet 205 to fall into the receiving groove a102 under gravity. Then, the rotating frame 201 continues to rotate, and the drive shaft 209 slides within the elliptical guide groove 104. As the rotating frame 201 rotates, the sliding frame 206... The moving frame 206 can periodically change its distance from the magnet 205. The drive shaft 209 on the side of the slide rod 208 slides in the elliptical ring-shaped guide groove 104 with chamfered edges on the inner wall of the frame 1. The guide groove 104 provides a specific trajectory for the movement of the drive shaft 209, thereby indirectly controlling the slide rod 208 and the connected sliding frame 206 to slide in the sliding groove 203 inside the rotating frame 201. When the sliding frame 206 moves above the receiving groove b103, the guide groove 104 will guide the sliding frame 206 away from the magnet 205. The magnetic force on the magnetic impurities in the transfer groove 207 becomes weaker and weaker and finally falls into the receiving groove b103. Since several frames 1 are arranged horizontally and several rotating shafts 202 are connected end to end, multiple impurity removal units 2 can work synchronously to form a multi-channel magnetic separation and impurity removal effect, which improves the efficiency and throughput of metal powder impurity removal.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
