Description

A device for preparing iron-silicon-aluminum metal magnetic powder cores Technical Field

[0001] This utility model relates to the technical field of iron-silicon-aluminum metal magnetic powder core preparation device; more specifically, it relates to an iron-silicon-aluminum metal magnetic powder core preparation device. Background Technology

[0002] Ferrosilicon-aluminum metal powder cores are a type of high-frequency soft magnetic material. Their interior is composed of alternating magnetic particles and non-conductive insulating layers, which can significantly reduce high-frequency eddy current losses. They also possess high permeability, low hysteresis loss, and good temperature stability. They are widely used in high-frequency inductors, transformers, and electromagnetic interference suppression devices. In particular, they have become the core material for high-frequency power electronic components due to their superior high saturation magnetic induction and DC bias resistance compared to ferrites.

[0003] Currently, existing iron-silicon-aluminum metal magnetic powder core preparation devices suffer from several drawbacks during operation. Firstly, metal powder may adhere to the inner wall of the device during mixing, leading to incomplete mixing. Secondly, metal powder may deposit at the bottom outlet, resulting in some powder remaining unmixed. This reduces the device's practicality. Furthermore, after mixing, some powder may not be completely broken down, or some dust may adhere to each other, causing the particle size of the metal powder to fail to meet standards. This could affect subsequent processes and further reduce the device's usability. Therefore, a new iron-silicon-aluminum metal magnetic powder core preparation device is urgently needed to address these issues. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an iron-silicon-aluminum metal magnetic powder core preparation device to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a device for preparing iron-silicon-aluminum metal magnetic powder cores, comprising:

[0006] The box body has a mixing structure inside the upper part of the box body, a screening structure inside one side of the box body, and a discharge port fixedly connected to the lower end of one side of the box body.

[0007] The mixing structure includes a mixing tank, and the mixing tank bearing is connected to the interior of the upper end of the housing;

[0008] The screening structure includes a filter plate, which is hinged to the interior of the box at the middle position.

[0009] Preferably, the mixing structure further includes a motor, which is mounted on the outer surface of one side of the housing. A rotating shaft is connected to the internal bearings on both outer surfaces of the mixing tank, and a connecting rod is fixedly connected to the outer surface of the rotating shaft. A mixing plate is fixedly connected to the outer surface of the connecting rod, and a scraper is fixedly connected to the outer surface of the outer end of the connecting rod. A rotating ring is fixedly connected to the outer surface of one side of the mixing tank, and positioning holes are provided inside the upper and lower outer surfaces of the rotating ring. A positioning rod is inserted into the inner surface of the upper outer surface of one side of the housing, and a compression spring is sleeved on the outer surface of the positioning rod. A sealing cover is threaded into the inner surface of the upper outer surface of the mixing tank. This design allows the rotating shaft to rotate by starting the motor.

[0010] Preferably, the output end of the motor is fixedly connected to the outer surface of one side of the rotating shaft. Multiple sets of connecting rods, mixing plates, and scrapers are provided. The connecting rods are evenly and coaxially arranged on the outer surface of the rotating shaft. The mixing plate is inclined. The outer surface of the outer end of the scraper is in contact with the inner wall surface of the mixing tank. This design can drive multiple sets of connecting rods, mixing plates, and scrapers to rotate synchronously through the rotation of the rotating shaft.

[0011] Preferably, the position of the positioning hole corresponds to the position of the positioning rod, and the internal size of the positioning hole is adapted to the external size of the positioning rod. The two ends of the retraction spring are respectively fixedly connected to the surface of one side of the positioning rod and the outer surface of one side of the housing. This design allows the positioning rod to be inserted into the corresponding positioning hole, and the positioning rod is more stable when it is inside the positioning hole.

[0012] Preferably, the screening structure further includes an electric telescopic rod, which is installed on the inner wall surface of one side of the box. Support plates are fixedly connected to the inner wall surfaces at both ends of the box. An installation groove is fixedly connected to the outer surface of the other side of the box, and a collection chamber is engaged inside the installation groove. A connecting plate is fixedly connected to the lower end of the box. This design allows for the filtration and screening of metal powder through the filter plate.

[0013] Preferably, the outer surface of the upper end of the electric telescopic rod abuts against the outer surface of the middle position of one side of the lower end of the filter plate, the outer surface of the upper end of the support plate is in contact with the outer surfaces of both ends of the lower end of the filter plate, and the position of the collection chamber corresponds to the position of the lower end of the filter plate. This design allows the upper end of the electric telescopic rod to support the lower end of the filter plate by activating the electric telescopic rod, thereby causing the filter plate to vibrate.

[0014] The technical effects and advantages of this utility model are as follows: By starting the motor, the rotating shaft can be driven to rotate, which in turn drives multiple sets of connecting rods, mixing plates, and scrapers to rotate synchronously. The mixing plates mix the metal powder, while the scrapers, which are attached to the inner wall of the mixing tank, rotate to remove the metal powder adsorbed on the inner wall. This prevents the metal powder from adsorbing on the inner wall of the mixing tank for a long time, thus avoiding affecting the mixing process. At the same time, the rotating positioning hole drives the mixing tank to rotate, and the elasticity of the spring itself drives the positioning rod to move inward automatically, so that the positioning rod automatically inserts into the corresponding positioning hole, thus positioning the mixing tank. This allows adjustment of the position of the opening at the top of the mixing tank. During the mixing process, it can prevent the metal powder from depositing at the bottom outlet of the mixing tank, thus preventing some powder from being mixed. When it is necessary to discharge, the mixing tank can be rotated so that the opening faces downward for discharge, which improves the practicality of the equipment to a certain extent.

[0015] By activating the electric telescopic rod, the upper end of the rod moves up and down reciprocally. The upper end of the electric telescopic rod supports the lower outer surface of the filter plate, causing the filter plate to vibrate. After mixing is completed, when the metal powder is discharged downwards from the inside of the mixing tank, the metal powder on the upper part of the filter plate can be filtered and screened. Some powder that does not meet the particle size standard will flow to the inside of the collection bin at the upper end of the filter plate and be collected for further processing. Powder that meets the standard will fall to the upper end of the connecting plate and enter the discharge port for subsequent processing. This ensures the standardization of the overall process and improves the practicality of the equipment to a certain extent. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Furthermore, the structural forms described in the following embodiments are merely illustrative. The iron-silicon-aluminum metal magnetic powder core preparation apparatus involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example 1

[0022] As shown in Figures 1-3, this embodiment proposes an apparatus for preparing iron-silicon-aluminum metal magnetic powder cores, comprising:

[0023] The box body 1 has a mixing structure 2 inside the upper part of the box body 1, and a screening structure 3 inside one side of the box body 1. The lower end of one side of the box body 1 is fixedly connected to the discharge port 4.

[0024] The mixing structure 2 includes a mixing tank 21, which is bearing-connected to the interior of the upper part of the housing 1. The mixing structure 2 also includes a motor 22, which is mounted on the outer surface of one side of the housing 1. A rotating shaft 23 is connected to the internal bearings on both outer surfaces of the mixing tank 21. A connecting rod 24 is fixedly connected to the outer surface of the rotating shaft 23, and a mixing plate 25 is fixedly connected to the outer surface of the connecting rod 24. A scraper 26 is fixedly connected to the outer surface of the outer end of the connecting rod 24. The output end of the motor 22 is fixedly connected to the outer surface of one side of the rotating shaft 23. Multiple sets of connecting rods 24, mixing plates 25, and scrapers 26 are provided, and the connecting rods 24 are evenly and coaxially arranged on the outer surface of the rotating shaft 23. The mixing plate 25 is inclined, and the outer surface of the scraper 26 at one end is in contact with the inner wall surface of the mixing tank 21. This design can drive the rotating shaft 23 to rotate by starting the motor 22, which can simultaneously drive multiple sets of connecting rods 24, mixing plate 25 and scraper 26 to rotate. The inclined design of the mixing plate 25 can improve the mixing efficiency of the mixing plate 25 in mixing metal powder inside the mixing tank 21 when the mixing plate 25 rotates. At the same time, the rotation of the scraper 26 with its outer surface in contact with the inner wall surface of the mixing tank 21 can scrape off the metal powder adsorbed on the inner wall surface of the mixing tank 21. The scraper 26 can also be more stable when rotating on the outer surface of the mixing tank 21.

[0025] A rotating ring 27 is fixedly connected to the outer surface of one side of the mixing tank 21. Positioning holes 28 are provided inside the upper and lower outer surfaces of the rotating ring 27. A positioning rod 29 is inserted into the inner surface of the upper outer surface of one side of the housing 1. A contraction spring 210 is fitted onto the outer surface of the positioning rod 29. A sealing cap 211 is threadedly connected to the inner surface of the upper outer surface of the mixing tank 21. The position of the positioning hole 28 corresponds to the position of the positioning rod 29, and the internal dimensions of the positioning hole 28 are adapted to the external dimensions of the positioning rod 29. The two ends of the contraction spring 210 are fixedly connected to the surface of one side of the positioning rod 29 and the outer surface of one side of the housing 1, respectively. This design allows the positioning rod 29 to move automatically inwards due to the elasticity of the contraction spring 210. When the rotating ring 27 rotates and the position of the positioning hole 28 corresponds to the position of the positioning rod 29, the positioning rod 29 can be automatically inserted into the interior of the positioning hole 28, thereby positioning the mixing tank 21 and adjusting the position of the opening of the mixing tank 21. Example 2

[0026] As shown in Figure 4, based on the same concept as the above embodiments, this embodiment also proposes:

[0027] The screening structure 3 includes a filter plate 31, which is hinged to the interior of the middle position of the box 1. The screening structure 3 also includes an electric telescopic rod 32, which is installed on the inner wall surface of one side of the box 1. Support plates 33 are fixedly connected to the inner wall surfaces of both ends of the box 1. An installation groove 34 is fixedly connected to the outer surface of the other side of the box 1, and a collection chamber 35 is engaged inside the installation groove 34. A connecting plate 36 is fixedly connected to the lower end of the box 1. The outer surface of the upper end of the electric telescopic rod 32 abuts against the outer surface of the middle position of the lower end of the filter plate 31. The outer surface of the upper end of the support plate 33 is attached to the outer surfaces of both ends of the lower end of the filter plate 31. The position of the collection chamber 35 corresponds to the position of the lower end of the filter plate 31.

[0028] In this embodiment, by activating the electric telescopic rod 32, the upper end of the electric telescopic rod 32 can be driven to move up and down reciprocally. At the same time, by the upper end of the electric telescopic rod 32 abutting against the outer surface of the lower end of the filter plate 31, the filter plate 31 can be driven to vibrate. Meanwhile, the support plate 33 supports the outer surfaces of the two ends of the lower end of the filter plate 31, which can prevent the filter plate 31 from falling off during vibration. Through the vibration of the filter plate 31, the metal powder on the upper end of the filter plate 31 can be filtered and screened more efficiently. Metal powder that does not meet the particle size standard will slide into the inside of the collection chamber 35, and the metal powder collected in the collection chamber 35 can be processed later.

[0029] Working principle: When using the equipment, first rotate and open the sealing cover 211, and inject the metal powder to be mixed through the opening at the top of the mixing tank 21. After injection, rotate and close the sealing cover 211 in the opposite direction, and then start the motor 22, which drives the rotating shaft 23 to rotate and drive the mixing plate 25 to mix the metal powder. At the same time, the scraper 26 scrapes off the metal powder on the inner wall surface of the mixing tank 21. After mixing is completed, rotate and open the sealing cover 211, and pull the positioning rod 29 outward to disengage it from the positioning hole 28. Then rotate the rotating ring 27 to align the position of the other set of positioning holes 28 with the position of the positioning rod 29, and then release the positioning rod 29 by retracting it. The elasticity of the spring 210 allows the positioning rod 29 to be re-inserted into the positioning hole 28, positioning the mixing tank 21. This allows the metal powder inside the mixing tank 21 to be discharged downwards through the opening of the mixing tank 21. At this time, the electric telescopic rod 32 can be activated. The impact of the electric telescopic rod 32 on the filter plate 31 causes the filter plate 31 to vibrate, thereby improving the efficiency of the filter plate 31 in filtering and screening metal powder. The powder that does not meet the standard is collected by the collection bin 35 for subsequent processing, while the powder that meets the standard will fall to the upper end of the connecting plate 36 and move into the discharge port 4 for subsequent processing. The above is the complete working principle of this utility model.

[0030] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.

Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
