Description

Technical Field

[0001] This utility model relates to the field of screening and grading for the production of iron-silicon-aluminum soft magnetic powder, and in particular to a screening and grading device for the production of iron-silicon-aluminum soft magnetic powder. Background Technology

[0002] As an important industrial material, iron-silicon-aluminum soft magnetic powder has a wide range of applications in many fields such as electronics and power. In the production of iron-silicon-aluminum soft magnetic powder, screening and grading devices play a crucial role. They can accurately separate magnetic powders of different particle sizes, thereby ensuring the quality and performance of the product. With the development of technology and the continuous improvement of market requirements for the quality of iron-silicon-aluminum soft magnetic powder, higher requirements are also placed on the performance and efficiency of screening and grading devices.

[0003] In existing screening and grading technologies for the production of iron-silicon-aluminum soft magnetic powder, common mechanical structures mainly include vibrating screens and drum screens. Vibrating screens use a motor to drive the screen body to vibrate at high frequency, causing the magnetic powder to jump on the screen surface, thereby separating magnetic powder of different particle sizes. Its technical principle is based on the gravitational settling and screening effect of magnetic powder under vibration. Smaller magnetic powder falls through the screen holes, while larger magnetic powder remains on the screen surface. Drum screens use the rotation of the drum to make the magnetic powder roll forward inside the drum, while screening through screens of different aperture sizes. During the rotation of the drum, due to the action of centrifugal force and gravity, the magnetic powder gradually moves closer to the screen. Magnetic powder that meets the screen aperture size passes through the screen, while those that do not meet the size continue to remain in the drum. These traditional screening and grading technologies can meet production needs to a certain extent, but their screening efficiency and accuracy are relatively limited.

[0004] However, during the production process, the brush, as an important component for cleaning the filter screen, is in contact with magnetic powder particles and the filter screen for a long time. Due to the hardness and special physical properties of the iron-silicon-aluminum soft magnetic powder, the brush bristles will wear down. At the same time, magnetic powder particles will continuously adhere to the bristles. In addition, the friction between the filter screen and the brush accelerates the aging of the brush. As the brush wears down and ages, its cleaning effect will be greatly reduced, and it will be unable to effectively clean the magnetic powder particles on the surface of the filter screen and inside the mesh. This will cause the filter screen to be easily clogged, thus affecting the normal operation of the screening and grading device. To solve the above problems, a screening and grading device for the production of iron-silicon-aluminum soft magnetic powder is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a screening and grading device for the production of iron-silicon-aluminum soft magnetic powder, which aims to improve the problem of wear and aging that occurs when the brush is in contact with magnetic powder particles and filter screen for a long time in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A screening and grading device for producing iron-silicon-aluminum soft magnetic powder includes a frame, a feed hopper at the top of the frame, a discharge hopper fixedly connected to the bottom of the feed hopper, a filter screen at the top of the frame, a disassembly assembly on the side wall of the frame, and a cleaning assembly on the outer wall of the frame.

[0008] The disassembly assembly includes a locking post, the outer wall of which is disposed on the side wall of the discharge hopper. A rotating post is rotatably connected inside the discharge hopper. A knob is disposed on the top of the rotating post. A housing is disposed on the bottom of the knob. The bottom of the knob is fixedly connected to the top of the locking post. A limiting post is fixedly connected to the bottom of the locking post. A spring is sleeved on the outer wall of the locking post. One end of the spring is fixedly connected to the top of the limiting post, and the other end of the spring is fixedly connected to the bottom of the knob. A sliding groove 1 and a sliding groove 3 are formed inside the housing. The outer wall of the limiting post is slidably connected inside the sliding groove 1.

[0009] As a further description of the above technical solution:

[0010] The cleaning component includes a brush, the outer wall of which is disposed on the side wall of the frame, and a housing is fixedly connected to the side wall of the frame.

[0011] As a further description of the above technical solution:

[0012] A motor is fixedly connected inside the outer casing. A rotating rod is fixedly connected to the output end of the motor. A gear is rotatably connected to the side wall of the rotating rod.

[0013] As a further description of the above technical solution:

[0014] A fixing block is fixedly connected inside the outer shell, and a second gear is fixedly connected to the side wall of the fixing block. The second gear meshes with the first gear.

[0015] As a further description of the above technical solution:

[0016] The gear is rotatably connected to a rotating rod on its outer wall, the fixed block has a sliding groove inside, and the discharge hopper has a support on its side wall.

[0017] As a further description of the above technical solution:

[0018] A sliding block is rotatably connected to the outer wall of the rotating rod, and a motor is fixedly connected to the top of the sliding block.

[0019] As a further description of the above technical solution:

[0020] The output end of the second motor is fixedly connected to one end of the rotating column, the outer wall of the sliding block is slidably connected to the inside of the second sliding groove, and the outer wall of the bracket is slidably connected to the side wall of the frame.

[0021] This utility model has the following beneficial effects:

[0022] In this invention, when the brush needs to be replaced, the knob is turned, which moves the locking post to a position, compressing the spring and causing the limiting post to rotate, disengaging it from the slide groove three. This allows the outer wall of the limiting post to slide within the slide groove one, and then the bottom of the limiting post disengages from the top of the brush. This achieves convenient brush replacement and solves the problem of wear and aging that occurs when the brush is in contact with magnetic powder particles and the filter screen for a long time. It reduces wear and resource pollution and ensures that the produced magnetic powder particles are purer.

[0023] In this invention, starting motor one drives the rotating rod to rotate, which in turn drives gear one to rotate. Since gear one meshes with gear two, it drives the rotating rod to rotate, causing the sliding block to slide in the sliding groove two. At the same time, starting motor two drives the brush to rotate, achieving the effect of effectively cleaning the filter screen. This solves the problems of magnetic powder particles sticking together and the filter screen being easily clogged by high humidity, thus ensuring screening efficiency. Attached Figure Description

[0030] 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.

[0031] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a screening and grading device for the production of iron-silicon-aluminum soft magnetic powder, comprising a frame 1, a feed hopper 2 at the top of the frame 1, the feed hopper 2 being designed as an inverted cone structure with a wide top and narrow bottom, the wide top opening facilitating the operator to quickly and in large quantities pour magnetic powder particles into it, improving feeding efficiency, avoiding damage due to long-term contact with magnetic powder particles, ensuring that the feed hopper 2 can work continuously and stably, maintaining the smoothness of the entire screening process, and a discharge hopper 3 fixedly connected to the bottom of the feed hopper 2 to ensure that there will be no blockage or leakage during the discharge process, ensuring the normal discharge of the screening machine and maintaining the continuity of production, a filter screen 4 at the top of the frame 1, the filter screen 4 having different screen hole sizes, allowing magnetic powder of different particle sizes to pass through the appropriate screen holes according to their own size, thereby achieving precise grading and producing products that meet different standards, a disassembly component on the side wall of the frame 1, and a cleaning component on the outer wall of the frame 1;

[0032] The disassembly assembly includes a locking post 12, the outer wall of which is set on the side wall of the discharge hopper 3. A rotating post 8 is rotatably connected inside the discharge hopper 3, allowing for prolonged rotation. A knob 9, made of high-strength engineering plastic injection molding with anti-slip texture, is located at the top of the rotating post 8. This knob provides easy hand rotation and a comfortable feel, allowing for precise control of the rotation angle. Rotating the knob 9 enables precise operation of subsequent components. A housing 10, made of aluminum alloy, is located at the bottom of the knob 9. Aluminum alloy is lightweight, high-strength, and corrosion-resistant, effectively protecting internal precision components such as the spring 11 from external dust and impurities. The bottom of the knob 9 is fixedly connected to the top of the locking post 12. A limiting post 23, made of wear-resistant hard alloy material, is fixedly connected to the bottom of the locking post 12. This limiting post 23 maintains its shape during prolonged sliding. The device is stable and not easily worn. A spring 11 is fitted on the outer wall of the locking post 12. One end of the spring 11 is fixedly connected to the top of the limiting post 23, and the other end of the spring 11 is fixedly connected to the bottom of the knob 9. The spring 11 plays a crucial role in buffering and resetting in the entire disassembly assembly. When the knob 9 rotates and causes the locking post 12 to move, the spring 11 is compressed and stores elastic potential energy. When resetting is required, the spring 11 releases the elastic potential energy and causes the locking post 12 to return to the initial position, ensuring that the operation of the entire disassembly assembly has good stability and repeatability. The housing 10 has a sliding groove 13 and a sliding groove 24 inside. The outer wall of the limiting post 23 is slidably connected to the inside of the sliding groove 13. The inner walls of these two sliding grooves are processed with high precision and have low surface roughness, ensuring that the outer wall of the limiting post 23 can slide smoothly inside the sliding groove 13. While achieving precise displacement of the components, it provides a reliable structural guarantee for convenient disassembly and replacement of related components.

[0033] Specifically, when the screening and grading device for producing iron-silicon-aluminum soft magnetic powder is working, the iron-silicon-aluminum soft magnetic powder first enters the screening area. During normal screening, qualified magnetic powder particles pass through filter screen 4, while unqualified particles are further processed or discharged. During long-term, high-intensity use, the bristles of brush 6 will wear and deform due to continuous friction, and a large amount of iron-silicon-aluminum soft magnetic powder impurities will also be adsorbed on the bristles. At this time, the operator only needs to turn knob 9. The rotation of knob 9 will cause the locking post 12 to move, and the movement of locking post 12 will further compress spring 11. At the same time, the bottom limiting post 23 will also rotate, moving from chute 3 24. After the brush 6 is disassembled, the outer wall of the limiting post 23 will slide inside the slide groove 13, eventually causing the bottom of the limiting post 23 to detach from the top of the brush 6. This completes the disassembly of the brush 6. When the brush 6 is replaced and reassembled, turn the knob 9 again, and the spring 11 will retract, causing the limiting post 23 to rotate. The outer wall of the limiting post 23 will slide back into the slide groove 24, realizing the assembly of the brush 6. This makes it easy to disassemble and replace the brush 6. By cleaning the adsorbed impurities and treating the deformed bristles in a timely manner, the cleaning function can be stably performed, effectively ensuring the continuous and efficient operation of the screening and grading device.

[0034] Reference Figure 1 and Figure 4The cleaning components include a brush 6, whose bristles are made of high-strength and highly flexible nylon. This material effectively removes organic magnetic powder particles adhering to the filter 4 without damaging it, ensuring the filter 4's lifespan. The outer wall of the brush 6 is located on the side wall of the frame 1, and a housing 5 is fixedly connected to the side wall of the frame 1. The housing 5 is made of thick cold-rolled steel plate, formed through precise stamping and welding processes, effectively protecting the internal motor 14 and other transmission components from impacts and dust. The motor 14 is fixedly connected inside the housing 5 for subsequent... The transmission system provides a continuous and stable power source to drive the entire cleaning assembly to operate normally. A rotating rod 15 is fixedly connected to the output end of motor 14, and a gear 16 is rotatably connected to the side wall of the rotating rod 15. The bearing used is a deep groove ball bearing, which features a low coefficient of friction, high speed, and high precision, ensuring that gear 16 rotates smoothly under the drive of the rotating rod 15, reducing energy loss, improving transmission efficiency, and providing a reliable guarantee for the smooth operation of the entire cleaning assembly. A fixing block 18 is fixedly connected inside the outer casing 5. The fixing block 18 is made of high-strength cast iron and precision-machined, possessing good stability and bearing capacity. The fixed block 18 has a fixed side wall with a gear 21, which meshes with a gear 16. During the meshing transmission, it can achieve precise speed ratio conversion and stable power transmission, rationally distributing the power of the motor 14 to the rotating rod 17, ensuring that the cleaning components run according to the predetermined motion trajectory and speed, effectively improving the cleaning effect of the brush 6 on the filter 4. The outer wall of the gear 16 is rotatably connected to the rotating rod 17, ensuring that it will not deform or be damaged during high-load transmission. The fixed block 18 has a sliding groove 22 inside, and the side wall of the discharge hopper 3 is equipped with a bracket 7. Made of metal, it has a certain rigidity and strength, providing stable support for the brush 6 and ensuring its stability during rotation. This allows the brush to better fit the filter screen 4 for cleaning, improving cleaning effect and efficiency. The outer wall of the rotating rod 17 is rotatably connected to a sliding block 20, and the top of the sliding block 20 is fixedly connected to a motor 19. The output end of the motor 19 is fixedly connected to one end of the rotating column 8. The outer wall of the sliding block 20 is slidably connected to the inside of the slide groove 22, and the outer wall of the bracket 7 is slidably connected to the side wall of the frame 1. This improves the screening efficiency of the organic magnetic powder particle screening machine and ensures the continuity and stability of production.

[0035] Specifically, during the screening and grading process of iron-silicon-aluminum soft magnetic powder production, due to the characteristics of the powder particles, filter screen 4 is easily clogged. Once clogged, the material cannot pass through smoothly, and the screening accuracy will be affected. When filter screen 4 is found to be clogged, the operator can start motor 14. After motor 14 starts, it will drive the rotating rod 15 to rotate, which in turn drives gear 16 to rotate. Since gear 16 meshes with gear 21, gear 16 will rotate inside gear 21. This causes the rotating rod 17 to rotate. When the rotating rod 17 rotates, the outer wall of the sliding block 20 slides inside the sliding groove 22. At the same time, the motor 19 is started, which drives the brush 6 to rotate. The rotation of the brush 6 can effectively clean the filter screen 4. During operation, the brush 6 efficiently cleans the magnetic powder particles clogging the surface and mesh of the filter screen 4, keeping the filter screen 4 unobstructed at all times. The iron-silicon-aluminum soft magnetic powder accurately passes through the filter screen 4 with the appropriate pore size according to its own particle size, and successfully completes the precise classification.

[0036] Working principle: After prolonged use, the bristles of brush 6 may become worn, deformed, or accumulate excessive impurities, affecting the cleaning effect. At this point, rotating knob 9 causes the locking post 12 to shift, which in turn compresses spring 11. Simultaneously, it rotates the bottom limiting post 23, disengaging it from the slide groove 24. This allows the outer wall of the limiting post 23 to slide within the slide groove 13, thus disengaging the bottom of the limiting post 23 from the top of brush 6, completing the disassembly of brush 6. When reassembling, rotating knob 9 again retracts spring 11, causing the limiting post 23 to rotate, sliding its outer wall within the slide groove 24, thus assembling brush 6. This allows for easy disassembly and cleaning of brush 6, ensuring the cleaning function remains in good working order and guaranteeing the efficient operation of the screening and grading device.

[0037] During production, filter screen 4 is easily clogged by magnetic powder particles, affecting the screening accuracy. At this time, motor 14 is started, which drives the rotating rod 15 to rotate, and then drives gear 16 to rotate. Since gear 16 meshes with gear 21, the outer wall of gear 16 rotates inside gear 21, which in turn drives the rotating rod 17 to rotate, causing the outer wall of sliding block 20 to slide inside sliding groove 22. At the same time, motor 219 is started, which drives brush 6 to rotate, thereby ensuring that iron-silicon-aluminum soft magnetic powder of different particle sizes can accurately pass through filter screen 4 with corresponding pore sizes, achieving precise classification.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
