Description

Technical Field

[0001] The present invention relates to the technical field related to ultra-high magnetic permeability powder, and in particular to a preparation device for ultra-high magnetic permeability powder. Background Art

[0002] Ultra-high magnetic permeability powder refers to powdered materials with abnormally high magnetic permeability values. Magnetic permeability is a physical quantity that measures the material's ability to conduct magnetic lines of force in a magnetic field. Ultra-high magnetic permeability means that the powder can gather and conduct magnetic fields very efficiently. This type of powder is usually made of specific magnetic materials, such as iron-based alloys, cobalt-based alloys, and some special soft magnetic materials. These materials are made into tiny granular powders through sophisticated preparation processes such as atomization and mechanical alloying. Ultra-high magnetic permeability powders have extremely critical applications in the electronics and electromagnetic fields. In terms of electronic components, they can be used to manufacture high-performance inductors, transformers, etc., which can significantly increase the inductance of these components and reduce energy loss, thereby improving the power conversion efficiency of electronic equipment and reducing electromagnetic interference. Interference, etc. For example, in the power management modules of modern smart phones, computers, etc., the use of inductor components containing ultra-high magnetic permeability powders helps to achieve more stable voltage-current conversion, extend battery life and reduce heat. In the field of electromagnetic shielding, it can be used as a key component of absorbing materials to effectively absorb and attenuate external electromagnetic waves, protect the internal circuits of electronic equipment from electromagnetic interference, or prevent the electromagnetic waves generated by electronic equipment themselves from leaking out and affecting other equipment. It plays an irreplaceable role in the military, communications, aerospace and other fields with extremely high requirements for electromagnetic compatibility. Ultra-high magnetic permeability powders usually need to reach a micron or even nanometer particle size to exhibit excellent magnetic properties. Therefore, ultra-high magnetic permeability powder preparation equipment is particularly needed.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 9The present invention provides a technical solution: a preparation device for ultra-high magnetic permeability powder, comprising a base 1, a foot support 2 is fixedly connected to the bottom of the base 1, a grinding box 3 is fixedly connected to the top of the base 1, a crushing box 4 is fixedly connected to the top of the grinding box 3, an adjustment mechanism 5 is arranged above the crushing box 4, a silo 6 is arranged above the adjustment mechanism 5, a crushing and grinding mechanism 7 is arranged on the surface of the grinding box 3 and the crushing box 4, and a filtering and storing mechanism 8 is arranged on one side of the grinding box 3;

[0028] The crushing and grinding mechanism 7 includes a protective shell 701, a second motor 702, a transmission gear 703, a first gear 704, a crushing roller 705, a filter screen 706, a second gear 707, a rotating shaft 708, a grinding wheel 709, a roller 710 and a crawler 711. The surfaces of the grinding box 3 and the crushing box 4 are fixedly connected with the protective shell 701, the outer side of the protective shell 701 is fixedly connected with the second motor 702, the inner end of the second motor 702 is fixedly connected with the transmission gear 703, one side of the transmission gear 703 is meshed with the first gear 704, and the transmission gear 703 and the first gear The inner end of 704 is fixedly connected with a crushing hob 705, the inner upper part of the grinding box 3 is fixedly connected with a filter screen 706, the lower part of the transmission gear 703 is meshed with a second gear 707, the inner end of the second gear 707 is fixedly connected with a rotating shaft 708, the surface of the rotating shaft 708 is fixedly connected with a grinding wheel 709, one end of the rotating shaft 708 is fixedly connected with a roller 710, the surface of the roller 710 is attached with a crawler 711, through the setting of the crushing and grinding mechanism 7, when the ultra-high magnetic permeability powder raw material is started to be processed, the second motor 702 is first started, and the second motor 70 2 drives the transmission gear 703 to rotate. When the transmission gear 703 rotates, on the one hand, it meshes with the first gear 704 to make the two crushing rollers 705 rotate in opposite directions. After the raw materials enter the crushing box 4 from the silo 6, they will be initially crushed and cut by the high-speed rotating and mutually coordinated crushing rollers 705, and the larger pieces of raw materials will be crushed into smaller particles. On the other hand, the transmission gear 703 meshes with the second gear 707 to drive the second gear 707 to rotate, thereby rotating the rotating shaft 708, and the grinding wheel 709 on the rotating shaft 708 rotates accordingly. The raw materials after initial crushing are The material falls into the grinding box 3 through the filter screen 706, and the grinding wheel 709 further grinds and refines it. At the same time, the roller 710 at one end of the rotating shaft 708 rotates, and drives other rollers 710 connected thereto to work together through the crawler 711 to ensure the continuity and efficiency of the entire grinding process. In this process, the protective shell 701 protects the internal transmission components and prevents dust from overflowing, so that the crushing and grinding mechanism 7 can operate stably and safely, and gradually grind the raw materials to the required micron or even nanometer particle size to meet the preparation requirements of ultra-high magnetic permeability powder.

[0029] Furthermore, multiple groups of foot supports 2 are arranged at the bottom of the base 1, and are symmetrically arranged at the four corners of the bottom of the base 1 with the central axis of the base 1. Through the arrangement of the foot supports 2, multiple groups of symmetrically distributed foot supports 2 provide an extremely stable support structure for the entire ultra-high magnetic permeability powder preparation equipment. During the operation of the equipment, whether it is the vibration generated by the high-speed operation of the crushing and grinding mechanism 7, or the unbalanced force generated when the material is transmitted and processed inside the equipment, it can be effectively dispersed and balanced through this symmetrical and stable foot support layout.

[0030] Furthermore, the adjustment mechanism 5 includes a support seat 501, a fixed block 502, a first motor 503, a threaded rod 504, a limiting rod 505, an adjustment slot 506, a slide bar 507, an adjustment block 508, a baffle 509 and a baffle outlet slot 510. The upper part of the crushing box 4 is fixedly connected to the support seat 501, the side of the support seat 501 is fixedly connected to the fixed block 502, one side of the fixed block 502 is fixedly connected to the first motor 503, the inner side of the first motor 503 is fixedly connected to the threaded rod 504, one end of the threaded rod 504 is fixedly connected to the limiting rod 505, and the support An adjusting groove 506 is provided on the side of the seat 501, a sliding rod 507 is fixedly connected to the inner end of the fixed block 502, an adjusting block 508 is slidably connected to the surface of the threaded rod 504 and the sliding rod 507, a baffle 509 is fixedly connected to the inner end of the adjusting block 508, a baffle outlet groove 510 is provided on the surface of the support seat 501, the fixed blocks 502 are arranged on both sides of the support seat 501, and the inner side of the fixed block 502 on the left side is rotatably connected to the threaded rod 504, and the inner side of the fixed block 502 on the right side is fixedly connected to the sliding rod 507, and the upper side of the fixed seat is fixedly connected to the silo, through the adjustment mechanism 5, when it is necessary to control the flow of materials from the silo 6 into the crushing box 4, the first motor 503 is started, and the first motor 503 drives the threaded rod 504 connected thereto to rotate. Since the adjustment block 508 is simultaneously sleeved on the threaded rod 504 and the slide bar 507, under the rotation of the threaded rod 504 and the guidance of the slide bar 507, the adjustment block 508 moves linearly along the threaded rod 504 and the slide bar 507. When the adjustment block 508 moves inward, the baffle 509 fixed on the inner side thereof also moves accordingly, and the baffle 509 is inserted into the baffle outlet slot 510 on the support seat 501. The passage between the outlet of the hopper 6 and the inlet of the crushing box 4 becomes narrower as the insertion depth of the baffle 509 increases, thereby reducing the flow rate of the material. Conversely, when the adjustment block 508 moves outward, the baffle 509 withdraws from the passage, and the flow rate of the material gradually increases. In this way, the flow rate of the material entering the crushing box 4 is accurately controlled to adapt to different crushing and grinding process requirements, ensuring that the ultra-high magnetic permeability powder raw materials can be efficiently crushed and ground at a suitable feeding speed, thereby improving the working efficiency of the equipment and the stability of product quality.

[0031] Furthermore, the threaded rods 504 are arranged at both ends of the limiting rod 505, and the threads of the two sets of threaded rods 504 correspond to each other. Through the arrangement of the threaded rods 504, the threaded rods 504 are arranged at both ends of the limiting rod 505 and the threads correspond to each other, which provides a reliable guarantee for the stable movement of the adjustment block 508. When the first motor 503 drives the threaded rod 504 to rotate, the adjustment block 508 can be smoothly displaced along a predetermined straight line trajectory due to the synergistic effect of the threaded rods 504 at both ends and the auxiliary positioning of the limiting rod 505. This symmetrical thread design ensures that the adjustment block 508 is stable when moving. No deviation, shaking or jamming will occur during the process, so that the baffle 509 connected thereto can accurately control the opening and closing degree of the material outlet of the silo 6, thereby realizing extremely precise adjustment of the material flow rate. Accurate material flow control is crucial for the preparation of ultra-high magnetic permeability powders. It can ensure that during the crushing and grinding process, the raw materials enter the crushing box 4 at an appropriate rate, avoiding insufficient crushing due to excessive feed or reducing production efficiency due to insufficient feed, thereby improving the consistency of product quality and the stability of the production process, reducing unqualified products due to unstable flow, and reducing production costs.

[0032] Furthermore, the position of the adjustment block 508 corresponds to the position of the adjustment slot 506, and the outer wall size of the adjustment block 508 matches the inner wall size of the adjustment slot 506. Through the setting of the adjustment slot 506 and the adjustment block 508, the adjustment block 508 corresponds to the position of the adjustment slot 506 and the size matches, which further enhances the accuracy and stability of the movement of the adjustment block 508. During the adjustment process, the adjustment slot 506 provides a precise guide path for the adjustment block 508, so that the adjustment block 508 can only move in a straight line along the direction of the adjustment slot 506 without deviating from the track, which helps to maintain the accuracy and reliability of the baffle 509 in controlling the material flow. Regardless of the length of the equipment operation time or the influence of external environmental factors, the accuracy and repeatability of each adjustment can be ensured. The stable adjustment mechanism is conducive to maintaining the stable operation of the entire preparation equipment, improving the level of automated control of the equipment, reducing manual intervention and process fluctuations caused by human operating errors, and laying a solid foundation for large-scale, high-precision production of ultra-high magnetic permeability powders, and improving production efficiency and the controllability of product quality.

[0033] Furthermore, multiple groups of grinding wheels 709 are arranged inside the grinding box 3, and one end of the rotating shaft 708 of the inner wall of each group of grinding wheels 709 is fixedly connected to a roller 710. Through the arrangement of the rotating shaft 708, the grinding wheel 709 and the roller 708, the design of multiple groups of grinding wheels 709 and one end of the rotating shaft 708 of the inner wall of each group of grinding wheels 709 being connected to the roller 710 significantly improves the grinding efficiency and effect. The multiple groups of grinding wheels 709 can grind the material falling into the grinding box 3 multiple times and at multiple angles, so that the material can be more fully crushed and refined, and reach the required micron or even nanometer level more quickly. The setting of the roller 710 is conducive to the coordinated work between multiple groups of grinding wheels 709 through transmission components such as the crawler 711, so that different groups of grinding wheels 709 can be operated at different speeds or directions, further enhancing the grinding effect on the material, simulating multiple grinding modes, and improving the adaptability to ultra-high magnetic permeability powder raw materials. It can process raw materials with different hardness and different initial particle sizes, thereby expanding the application range of the equipment, and at the same time improving the uniformity and consistency of grinding, reducing the product performance differences caused by uneven grinding, and improving the overall quality and performance of ultra-high magnetic permeability powder.

[0034] Furthermore, the filtering and storing mechanism 8 comprises an extraction pipe 801, an extraction box 802, a support frame 803, a fan 804, a box cover 805, a storage box 806, a slide 807, a primary filter plate 808, a secondary filter plate 809, a tertiary filter plate 810, a slider 811, a stopper 812, a telescopic pipe 813, a telescopic rod 814, a telescopic spring 815, a clamping block 816 and a clamping hole 817. One side of the grinding box 3 is fixedly connected with the extraction pipe 801, the surface of the extraction pipe 801 is provided with the extraction box 802, the inner wall of the extraction box 802 is fixedly connected with the support frame 803, the inner side of the support frame 803 is installed with a fan 804, the bottom of the other end of the extraction pipe 801 is connected with the box cover 805, and the bottom of the box cover 805 is connected with the storage box 80 6. A chute 807 is provided on the inner side of the storage box 806. A primary filter plate 808 is installed inside the storage box 806. A secondary filter plate 809 is installed inside the storage box 806. A tertiary filter plate 810 is installed inside the storage box 806. Slide blocks 811 are fixedly connected to the middle parts of both sides of the primary filter plate 808, the secondary filter plate 809 and the tertiary filter plate 810. A stopper 812 is fixedly connected above the slide block 811. One end of the stopper 812 is fixedly connected to a telescopic tube 813. A telescopic rod 814 is slidably connected inside the telescopic tube 813. A telescopic spring 815 is wound around the outer side of the telescopic rod 814. A clamping block 816 is fixedly connected to one end of the telescopic rod 814 and the telescopic spring 815. A clamping hole 817 is provided on the inner side of the chute 807. By setting the filtering and storing mechanism 8, in the process of preparing the ultra-high magnetic permeability powder, when the ground powder needs to be filtered and stored, the fan 804 on the support frame 803 in the extraction box 802 is started, and the fan 804 rotates to generate suction, so that the ground powder in the grinding box 3 is sucked in through the extraction pipe 801, and the powder first enters the storage box 806, and is filtered by the primary filter plate 808, the secondary filter plate 809 and the tertiary filter plate 810 in the storage box 806 in turn. The primary filter plate 808 can intercept larger particles of impurities or insufficiently ground materials, the secondary filter plate 809 further filters the particles of medium particle size, and the tertiary filter plate 810 finely filters the fine particles, thereby realizing the graded filtration of the powder, improving the quality of the powder. In order to improve the purity and uniformity of powder, when installing the filter plate, align the sliders 811 on both sides of the primary filter plate 808, the secondary filter plate 809 and the tertiary filter plate 810 with the slide groove 807 on the inner side of the storage box 806 and insert them. When the block 816 on the slider 811 moves to the corresponding hole 817 position on the slide groove 807, under the action of the telescopic spring 815, the block 816 pops out and snaps into the hole 817 to fix the filter plate. If the filter plate needs to be removed for cleaning or replacement, press the block 16 to retract it into the telescopic tube 813 to overcome the elastic force of the telescopic spring 815, and then the filter plate can be pulled out from the slide groove 807. The qualified ultra-high magnetic permeability powder after filtration is collected at the bottom of the storage box 806 for subsequent use or further processing.

[0035] Furthermore, the position of the slider 811 corresponds to the position of the slide groove 807, and the outer wall size of the slider 811 matches the inner wall size of the slide groove 807. Through the arrangement of the slide groove 807 and the slider 811, the slider 811 corresponds to the position of the slide groove 807 and the size matches, which provides accurate and stable positioning and guidance for the installation of the filter plate in the storage box 806. When installing the filter plate, the slider 811 is smoothly inserted along the slide groove 807 to ensure that the filter plate can be accurately placed in the predetermined position without deviation, skewness or shaking. This precise installation method ensures that the filter plate is installed in a stable manner. The spacing between the filter plates is uniform, so that the powder can be filtered according to the designed filtration order and accuracy when passing through each level of filter plates, avoiding problems such as reduced filtration effect or powder leakage caused by improper installation of the filter plates. At the same time, the stable installation structure is also beneficial during the operation of the equipment. The filter plates can withstand the impact of airflow and powder and maintain their positions unchanged, which improves the reliability and stability of the filtration system, reduces the number of frequent maintenance and adjustments required due to filter plate displacement, extends the service life of the equipment, reduces maintenance costs, and ensures the continuity and efficiency of the ultra-high magnetic permeability powder filtration and storage process.

[0036] Furthermore, the aperture of the primary filter plate 808 is larger than that of the secondary filter plate 809, and the aperture of the secondary filter plate 809 is larger than that of the tertiary filter plate 810. Through the arrangement of the primary filter plate 808, the secondary filter plate 809 and the tertiary filter plate 810, the apertures of the primary filter plate 808, the secondary filter plate 809 and the tertiary filter plate 810 are successively decreased to form an efficient graded filtration system. The primary filter plate 808 first intercepts larger particles of impurities and insufficiently ground materials by virtue of its larger aperture, preventing these large particles from clogging or damaging the subsequent secondary filter plate 809 and the tertiary filter plate 810, thus playing a role of preliminary screening and protection. The secondary filter plate 809 further filters the impurities. The medium-sized particles are used to further purify the powder and reduce the impact of medium-sized impurities on the quality of the final product. The three-stage filter plate 810 uses a smaller aperture to finely filter the fine particles, ensuring that only ultra-high magnetic permeability powders with tiny particle sizes that meet the requirements can pass through, thereby significantly improving the purity and particle size uniformity of the powder. This graded filtration method can effectively remove impurities in different particle size ranges, so that the powder finally collected at the bottom of the storage box 806 is of higher quality, meeting the strict requirements for purity and particle size of ultra-high magnetic permeability powders in high-end electronic devices and other application fields, improving product performance and competitiveness, and helping to promote technological development and product quality improvement in related industries.

[0037] Working principle: First, the raw material is placed in the silo 6, and then the first motor 503 of the adjustment mechanism 5 is started according to the required feeding speed. The first motor 503 drives the threaded rod 504 to rotate, so that the adjustment block 508 moves along a predetermined straight line trajectory under the guidance of the slide bar 507 and the auxiliary positioning of the limit rod 505, and then drives the baffle 509 to accurately control the opening and closing degree of the channel between the outlet of the silo 6 and the inlet of the crushing box 4 through the baffle outlet groove 510, and the raw material is fed into the crushing box 4 at a suitable flow rate. The raw material entering the crushing box 4 is started in the crushing and grinding mechanism 7 by the second motor 702, which drives the transmission gear 703 to rotate, and the transmission gear 703 is meshed with the first gear 704 to make the crushing roller 705 face each other. The raw materials are initially crushed and cut into smaller particles by rotating, and the initially crushed materials fall into the grinding box 3 through the filter screen 706. At this time, the transmission gear 703 is meshed with the second gear 707 to drive the rotating shaft 708 to rotate, and the multiple groups of grinding wheels 709 on the rotating shaft 708 rotate accordingly. At the same time, the roller 710 at one end cooperates with other rollers 710 through the crawler 711 to make different groups of grinding wheels 709 operate at different speeds or directions, and grind the materials at multiple angles and multiple times, so that the materials gradually reach the micron or even nanometer particle size. During the whole crushing and grinding process, the protective shell 701 plays a role in protecting the internal transmission components and preventing dust from overflowing, and the multiple groups of symmetrical foot supports 2 at the bottom of the equipment effectively disperse and level the materials. The vibration and unbalanced force generated by the operation of the equipment are balanced to ensure the stable operation of the equipment. When the grinding is completed, the fan 804 on the support frame 803 in the extraction box 802 of the filter storage mechanism 8 is started to generate suction to suck the powder in the grinding box 3 into the storage box 806 through the extraction pipe 801. In the storage box 806, the powder is filtered in sequence by the first-level filter plate 808, the second-level filter plate 809 and the third-level filter plate 810 with decreasing apertures. The first-level filter plate 808 intercepts large particles of impurities and insufficiently ground materials, the second-level filter plate 809 filters medium-sized particles, and the third-level filter plate 810 finely filters fine particles, thereby improving the purity and particle size uniformity of the powder. The filter plate is precisely matched with the slider 811 and the slide 807 It is installed in the storage box 806. During installation, the block 16 on the slider 811 is inserted into the hole 817 of the slide groove 807 under the action of the telescopic spring 15 to be fixed. If the filter plate needs to be cleaned or replaced, the block 16 is pressed to retract the telescopic tube 813 to overcome the elastic force and then the filter plate can be pulled out. Finally, the qualified ultra-high magnetic permeability powder after filtration is collected at the bottom of the storage box 806 and can be used for subsequent use or further processing. The entire device realizes efficient and accurate preparation of ultra-high magnetic permeability powder through the coordinated operation of various mechanisms. The model of the first motor 503 is YE2-132S-4, and the model of the second motor 702 is Y315S-2. In this way, the use process of the ultra-high magnetic permeability powder preparation equipment is completed.
