Description

Technical Field

[0001] This utility model belongs to the field of magnetic material drying technology, specifically relating to a drying oven for processing magnetic materials. Background Technology

[0002] Magnetic materials, as indispensable key materials in modern industry and technology, play a crucial role in numerous sectors such as electronics, electrical engineering, communications, automotive, and aerospace. In the field of electronic communications, high-precision electronic components rely on the uniform composition and microstructure of magnetic materials to ensure the accuracy and stability of signal transmission. In the new energy vehicle industry, high-performance permanent magnet motors require magnetic materials with higher magnetic energy product and coercivity to improve motor efficiency and power density. With the continuous innovation of technologies in these industries, increasingly stringent requirements are being placed on the performance, quality, and stability of magnetic materials. Since the flow of hot air inside the drying chamber mainly relies on natural convection, the flow speed is relatively slow, resulting in uneven heat transfer, slow material drying speed, and long drying cycle. Therefore, the inventors have proposed a drying chamber for processing magnetic materials. Utility Model Content

[0003] (1) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a drying oven for processing magnetic materials, aiming to solve the problems of uneven heat transfer, slow material drying speed, and long drying cycle caused by the fact that the flow of hot air in the oven mainly relies on natural convection, which results in a slow flow speed.

[0005] (2) Technical solution

[0006] To address the aforementioned technical problems, this utility model provides a drying oven for processing magnetic materials, comprising a support frame, a drying chamber, and a fixed frame. The support frame has a U-shaped structure, and the drying chamber is movably disposed within the support frame. A door is hinged to the upper surface of the drying chamber, and an electric heating plate is installed on the inner wall of the drying chamber. An L-shaped fixed frame is fixedly installed on the upper surface of the support frame, with a vertically arranged fixed rod fixedly connected to the end of the fixed frame away from the support frame, and a driving block fixedly connected to the end of the fixed rod away from the support frame. A horizontally opening movable groove is formed on the upper surface of the drying chamber, and the driving block is slidably installed along the movable groove. A rotating disk is rotatably connected to the bottom end of the driving block, and a vertically arranged stirring shaft is located below the rotating disk. Through the lateral movement of the drying chamber and the rotation of the stirring shaft, a dual drying effect is achieved. The movement of the drying chamber causes the material to continuously shake, increasing the opportunity for contact with hot air.

[0007] Preferably, a drive gear is internally mounted on the drive block for rotation.

[0008] Preferably, the inner wall of the movable groove has mating grooves arranged in a straight line, and the drive gear is adapted to the mating grooves.

[0009] Preferably, the drive block has an opening on the surface facing the mating groove, and the drive gear is exposed through the opening.

[0010] Preferably, the upper surface of the support frame is provided with an installation groove, and a telescopic cylinder is embedded in the installation groove.

[0011] Preferably, the extended end of the telescopic cylinder is fixedly connected to a connecting block, and the connecting block is fixedly connected to the outer wall of the drying chamber.

[0012] Preferably, the support frame has a horizontally formed groove, and the connecting block passes through the groove.

[0013] (3) Beneficial effects

[0014] Compared with existing technologies, the advantages of this invention are as follows: In traditional drying equipment, hot air mainly relies on natural convection, which is slow and uneven in heat transfer, resulting in slow drying speed and long cycles. This drying chamber, however, achieves a dual effect of promoting drying through the lateral movement of the drying chamber and the rotation of the stirring shaft. The movement of the drying chamber causes the material to constantly shake, increasing its contact with hot air; the stirring of the stirring shaft further accelerates the evaporation of moisture or solvents inside the material, greatly shortening the drying time and improving drying efficiency. This meets the demand for high-efficiency drying in the large-scale production of magnetic materials. During the drying process, due to the lateral movement of the drying chamber and the rotation of the stirring shaft, the magnetic material is in a dynamic state within the drying chamber, avoiding localized overheating or insufficient drying. The material can absorb heat evenly, and moisture or solvents can evaporate evenly, thus ensuring the uniformity and consistency of drying quality. This helps improve the performance stability of magnetic materials and meets the stringent quality requirements of high-end industries. Attached Figure Description

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.

[0027] This specific embodiment is a drying oven for processing magnetic materials, and its structural schematic diagram is shown below. Figure 1 , Figure 2 As shown, the assembly includes a support frame 1, a drying chamber 2, and a fixing frame 4. The support frame 1 has a U-shaped structure. The drying chamber 2 is movably disposed within the support frame 1. A door is hinged to the upper surface of the drying chamber 2, and an electric heating plate is installed on the inner wall of the drying chamber 2. An L-shaped fixing frame 4 is fixedly installed on the upper surface of the support frame 1. A vertically arranged fixing rod 3 is fixedly connected to the end of the fixing frame 4 away from the support frame 1, and a driving block 11 is fixedly connected to the end of the fixing rod 3 away from the support frame 1. An installation groove 6 is formed on the upper surface of the support frame 1, and a telescopic cylinder 8 is embedded in the installation groove 6. A connecting block 5 is fixedly connected to the extended end of the telescopic cylinder 8, and the connecting block 5 is fixedly connected to the outer wall of the drying chamber 2. A horizontal sliding groove 7 is formed on the support frame 1, and the connecting block 5 passes through the sliding groove 7.

[0028] Reference Figure 3 , Figure 4 The upper surface of the drying chamber 2 has a horizontally opening movable groove 10. A drive block 11 is slidably installed along the movable groove 10. A rotating disk 12 is rotatably connected to the bottom end face of the drive block 11. A vertically arranged stirring shaft 14 is provided below the rotating disk 12. A drive gear 13 is rotatably embedded inside the drive block 11. Matching grooves 9 are arranged in a row on the inner wall of the movable groove 10, and the drive gear 13 is adapted to the matching grooves 9. An opening is opened on the surface of the drive block 11 facing the matching groove 9, and the drive gear 13 is exposed through the opening.

[0029] Working principle: The operator opens the hinged door on the upper surface of the drying chamber 2, puts the magnetic material to be dried into the drying chamber 2, and then closes the door to ensure that the drying process is carried out in a relatively sealed environment to reduce heat loss.

[0030] When the power is turned on, the electric heating plate installed on the inner wall of the drying chamber 2 starts to work, releasing heat to heat the air inside the drying chamber 2, causing the internal temperature of the drying chamber 2 to gradually rise, providing a heat source for drying the magnetic materials.

[0031] The telescopic cylinder 8, embedded in the mounting groove 6 on the support frame 1, is activated. The extended end of the telescopic cylinder 8 pushes the connecting block 5 to move within the horizontally opened sliding groove 7 on the support frame 1. Since the connecting block 5 is fixedly connected to the outer wall of the drying chamber 2, the drying chamber 2 will move laterally in the horizontal direction within the support frame 1. During the lateral movement of the drying chamber 2, the fixed rod 3 fixedly connected to the fixed frame 4 drives the drive block 11 to slide along the horizontally opened moving groove 10 on the upper surface of the drying chamber 2. The drive gear 13 inside the drive block 11 is adapted to the mating grooves 9 arranged in a row on the inner wall of the moving groove 10. When the drive block 11 moves, the drive gear 13 rotates under the action of the mating grooves 9. The rotating disk 12 rotatably connected to the bottom end of the drive block 11 is connected to the drive gear 13. The rotation of the drive gear 13 drives the rotating disk 12 to rotate, which in turn drives the vertically arranged stirring shaft 14 below the rotating disk 12 to rotate.

[0032] The lateral movement of drying chamber 2 causes the magnetic material inside to constantly oscillate, increasing the contact area and frequency between the material and the hot air, resulting in more uniform heating of the material. At the same time, the rotation of stirring shaft 14 agitates the magnetic material, further breaking down local temperature and humidity differences within the material, accelerating the evaporation of moisture or solvent, and achieving efficient drying of the magnetic material.

[0033] Material discharge completed: After the drying time reaches the preset time or meets the drying requirements, turn off the electric heating plate and telescopic cylinder 8. After the temperature inside the drying chamber 2 drops to a safe range, open the chamber door and take out the dried magnetic material to complete the entire drying process.

[0034] 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.
