Description

Technical Field

[0001] This utility model relates to the field of magnetic ring heating technology, specifically a magnetic ring heating furnace. Background Technology

[0002] Magnetic ring heating furnaces utilize the principle of electromagnetic induction to convert electrical energy into heat energy. Publication number CN222147837U discloses a furnace body for an electromagnetic heating furnace, including an integrated control base, an outer shell, and an inner shell. A display panel and a control panel are located on the outer side of the integrated control base. The outer shell is fixedly connected to the upper outer side of the integrated control base. The outer shell has a high-temperature resistant coating, and a partition is fixedly connected to the inner side of the outer shell. The side of the partition away from the integrated control base is in close contact with a metal-ceramic barrel. A limit rod is slidably connected to the inner side of the metal-ceramic barrel. A heat-insulating cylinder is fixedly connected to the outer side of the limit rod, and a heat-conducting cylinder is fixedly connected to the inner side of the heat-insulating cylinder. While this method offers significant advantages, during heating, the spring clip is in close contact with the metal-ceramic barrel, limit rod, heat-insulating cylinder, heat-conducting cylinder, and inner shell. This close contact causes dimensional changes due to thermal expansion. The spring clip's tight contact with the components restricts its free movement during thermal expansion, leading to deformation, breakage, or even damage to the components in close contact, such as the metal-ceramic barrel.

[0003] Therefore, we propose a magnetic ring heating furnace. Utility Model Content

[0017] 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.

[0018] Example

[0019] Please see Figures 1-3The illustrated magnetic ring heater includes an outer shell 1 containing a metal-ceramic barrel 2. A pressure plate 3 is located on one side of the metal-ceramic barrel 2. An insulation cylinder 4 is located inside the metal-ceramic barrel 2, and another pressure plate 3 is located on one side of the insulation cylinder 4. An inner shell 5 is located inside the insulation cylinder 4. Pressure plates 3 are tightly pressed against the outer side of the inner shell 5. Each pressure plate 3 is slidably connected to a slide rod 6. The slide rod 6 is fixedly connected to the inside of a main pressure plate 7. Multiple springs 8 are located inside the slide rod 6. The main pressure plate 7 is slidably connected to the inside of a retaining spring 9. A cover 10 is located above the retaining spring 9. An electromagnetic tube 1 is located below the inner shell 5. 1. A partition plate 12 is provided below the electromagnetic tube 11. This utility model has a pressure plate on one side of the metal ceramic barrel and a pressure plate on the same side of the inner side of the heat preservation cylinder. The pressure plates are tightly pressed together on the outer side of the inner shell. The pressure plates are slidably connected to the slide rods. The slide rods are fixedly connected inside the main pressure plate. The slide rods are fitted with multiple springs. The main pressure plate is slidably connected to the inner side of the snap rings. Through the cooperation of the slide rods and springs, the buffering and movement functions are realized. The snap rings are engaged with the outer shell, which effectively prevents the problem of breakage due to inability to move when thermal expansion causes dimensional changes during the heating process.

[0020] Furthermore, the retaining ring 9 has a groove for installation, which is slidably connected to the connecting plate 901. The groove on the retaining ring is specifically designed for installation, and it can be slidably connected to the connecting plate. During installation, simply push the connecting plate into the groove to achieve a secure connection between the retaining ring and the connecting plate. During disassembly, simply pull the connecting plate out of the groove in the opposite direction to ensure that the retaining ring is a single unit.

[0021] Furthermore, the snap ring 9 is threadedly connected to the threaded rod 13, and the threaded rod 13 is slidably connected to the main pressure plate 7. Through the threaded connection between the snap ring and the threaded rod, and the sliding connection between the threaded rod and the main pressure plate, the operator can precisely control the position of the main pressure plate by rotating the threaded rod. When the position of the main pressure plate needs to be finely adjusted, simply rotate the threaded rod, and the main pressure plate will move along the axial direction of the threaded rod. The distance of movement can be accurately calculated based on the number of rotations, ensuring that the main pressure plate is accurately installed in the required position. At the same time, when the working conditions change, the main pressure plate can slide along the threaded rod and be quickly adjusted in conjunction with the position of the snap ring to adapt to different environments, ensuring that the equipment can work stably and reliably under various working conditions.

[0022] Furthermore, a spring groove is formed on the inner side of the main pressure plate 7, and a second spring 14 is installed inside the spring groove. The second spring 14 is tightly pressed against the bottom surface of the retaining spring 9. The main pressure plate has a carefully designed spring groove on its inner side, and the second spring is cleverly positioned within the groove and tightly pressed against the bottom surface of the retaining spring. This tight pressing of the second spring against the bottom surface of the retaining spring provides stable elastic support for the main pressure plate. During equipment operation, the main pressure plate may be subjected to forces from different directions. The elastic characteristics of the second spring can adaptively adjust according to the force on the retaining spring, always providing support to the main pressure plate. This ensures that the main pressure plate maintains a relatively stable position under various working conditions, preventing displacement or shaking due to external forces, thereby ensuring the normal operation of the equipment.

[0023] Furthermore, the main pressure plate 7 is internally connected to the pressure plate 3, which tightly presses against the spring 8. The pressure plate 8 is slidably connected to the main pressure plate, allowing it to move freely within the main pressure plate in a specific direction. Simultaneously, the pressure plate tightly presses against the spring, which is under compression. When the equipment is subjected to external forces or the working environment changes, the pressure plate can slide within the main pressure plate, thus stabilizing the metal-ceramic drum, the insulation cylinder, and the inner shell.

[0024] Furthermore, spring 8 is sleeved on the outside of slide rod 6, and spring 8 at both ends of slide rod 6 is tightly pressed against the inner wall of main pressure plate 7. Through the outside of the spring, springs are set at both ends of slide rod, which are tightly pressed against the inner wall of main pressure plate, thereby ensuring that pressure plate is always given a reverse support force, ensuring that pressure plate can maintain a relatively stable position under various working conditions, avoiding displacement or shaking due to external force, thereby ensuring the normal operation of equipment.

[0025] In this solution, the workflow is as follows: During equipment operation, the inner shell 5, the insulation cylinder 4, and the metal-ceramic barrel 2 will undergo thermal expansion due to temperature changes. Each component has a certain amount of movement space during thermal expansion. Since the pressure plate 3 is slidably connected to the slide rod 6, when the component expands thermally, the pressure plate 3 can slide on the slide rod 6. At the same time, the pressure plate 3 tightly presses against multiple springs 8, thereby driving each component to make minor position adjustments. This avoids stress concentration caused by thermal expansion that could damage the component, thus improving the reliability and service life of the equipment.
