Abstract
Description
Technical Field
[0001] This utility model relates to the field of ferrite material production technology, specifically to a powder drying oven for ferrite material production. Background Technology
[0002] Ferrite is a non-metallic magnetic material formed by sintering iron oxides with other metal oxides. Due to its unique magnetic and electrical properties, ferrite has become an indispensable material in modern electronic and magnetic devices, especially in high-frequency and low-voltage fields, where it plays an irreplaceable role. If ferrite powder is in a wet state, the presence of water molecules or binder molecules between particles weakens the van der Waals forces, leading to particle agglomeration. Agglomeration reduces the specific surface area of the powder, affecting the diffusion efficiency of oxygen ions during subsequent sintering, thereby reducing sintering density and material properties. Therefore, ferrite powder needs to be dried during production.
[0003] Dry powder is more likely to form a dense porous structure at high temperatures. The evaporation or decomposition of moisture or binders at high temperatures provides a smoother channel for oxygen ion diffusion, promoting densification of the sintered body and improving the mechanical properties of the material. However, existing ferrite powder drying equipment suffers from poor drying effects, leading to powder accumulation, uneven drying, and internal clumping, thus reducing work efficiency. Therefore, we provide a powder drying oven for ferrite material production. Utility Model Content

[0011] A further improvement of this utility model is that: the two ends of the drive rod are provided with rolling wheels on one side of the scraper, and an anti-blocking rod is fixedly sleeved on the outer surface of the other end of the drive rod.

[0027] like Figure 1-5As shown, this utility model provides a powder drying box for ferrite material production, including a drying box 1. A support bracket 2 is provided on the bottom of the drying box 1. The inner side of the right end of the support bracket 2 is rotatably connected to both sides of the right end of the drying box 1.

An electric heating tube 14 is provided inside the cavity 13. Insulation cotton 15 is fixedly connected to the inner wall of the cavity 13.
[0028] Furthermore, the drying chamber 1 can be heated by energizing the electric heating tube 14, thereby drying the powder inside the drying chamber 1. The electric heating tube 14 is covered with heat insulation cotton 15, which can reduce the heat loss of the electric heating tube 14 and thus improve the heating of the drying chamber 1 by the electric heating tube 14.
[0029] Example 2
[0030] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a support frame 16 is fixedly installed on the outer surface of the left end of the drying oven 1, a servo motor 17 is fixedly installed inside the support frame 16, a drive rod 18 is fixedly installed on the output end of the servo motor 17, the other end of the drive rod 18 extends to the right end inside the drying oven 1, a stirring rod 19 is fixedly sleeved on the outer surface of the drive rod 18, multiple sets of stirring rods 19 are provided, scrapers 110 are fixedly sleeved at both ends of the drive rod 18, rolling wheels 111 are provided on one side of the scraper 110 at both ends of the drive rod 18, and an anti-blocking rod 112 is fixedly sleeved on the outer surface of the other end of the drive rod 18.
[0031] Furthermore, the output of the servo motor 17 drives the drive rod 18 to rotate at a constant speed. When the drive rod 18 rotates, it drives the stirring rod 19 to rotate between the powder, promoting the flowability of the powder and further promoting uniform drying. The rotation generates centrifugal force to push the powder to the surroundings. The drive rod 18 drives the rolling wheel 111 to roll the powder around, so that the agglomerates in the powder are broken up. At the same time, the scraper 110 follows closely behind to scrape off the powder adhering to the inner wall of the drying chamber 1.
[0032] Example 3
[0033] like Figure 1-5As shown, based on embodiments 1-2, this utility model provides a technical solution: preferably, the feeding unit includes a rotating shaft 12 fixedly installed at the bottom of the drying chamber 1, an extension plate 41 fixedly installed at the bottom left side of the support bracket 2, a rotating shaft 42 fixedly installed at the top of the extension plate 41, an electric telescopic column 43 rotatably connected at the inner axis of the rotating shaft 42, the other end of the electric telescopic column 43 rotatably connected to the inside of the rotating shaft 12, a conical hopper fixedly connected at the right side of the drying chamber 1, and an outlet 11 fixedly installed at the output end of the conical hopper.
[0034] Furthermore, the extension is initiated by the electric telescopic column 43, which in turn pushes the rear end of the drying chamber 1 to move upward, while the front end of the drying chamber 1 rotates on the inner side of the support bracket 2. At this time, the drying chamber 1 is in an inclined state, which makes the discharge more thorough. At the same time, the rotation of the drive rod 18 drives the anti-blocking rod 112 to rotate as well, rotating at the outlet 11 to prevent blockage at the outlet 11.

The electric heating tube 14 is energized to heat the drying chamber 1, thus drying the powder inside. Insulation cotton 15 is laid outside the electric heating tube 14 to reduce heat loss and improve its heating effect on the drying chamber 1. During the powder drying process, the output of the servo motor 17 drives the drive rod 18 to rotate at a constant speed. The rotation of the drive rod 18 causes the stirring rod 19 to rotate between the powder particles, promoting powder flowability and further promoting uniform drying. The rotation generates... The powder is pushed outwards by the force of the drive rod 18, which drives the crushing wheel 111 to crush the powder around it, breaking up any clumps in the powder. At the same time, the scraper 110 follows closely behind, scraping off the powder adhering to the inner wall of the drying chamber 1, further improving processing efficiency. When discharging, the electric telescopic column 43 is activated to extend, which pushes the rear end of the drying chamber 1 upwards, while the front end of the drying chamber 1 rotates on the inner side of the support bracket 2. At this time, the drying chamber 1 is in an inclined state, making the discharge more thorough. At the same time, the rotation of the drive rod 18 drives the anti-blocking rod 112 to rotate as well, rotating at the outlet 11 to prevent blockage at the outlet 11.
