[0025] specifically refer to Figure 1-3This utility model relates to an electromagnetic induction coil frame, applied in the field of complete sets of equipment for heating materials using electromagnetic induction technology. It provides a stable, insulated, and easily assembled and maintained support structure for the electromagnetic induction coil, ensuring coil installation accuracy and equipment operational stability, and adapting to different coil specifications and operating conditions. Its structure includes: an inner frame 101, insulating columns 102, an insulating support plate, and an insulating plate 103. The inner frame 101 is a cuboid frame composed of multiple columnar structures connected by bolts. Multiple insulating columns 102 are evenly distributed on the sides of the inner frame 101, with the positions of the insulating columns 102 on the two sides of the inner frame 101 corresponding to each other. The insulating support plate is bolted to the front of the inner frame 101 and includes an upper insulating support plate 104 and a lower insulating support plate 103. The shape of the support plate 105, the upper insulating support plate 104, and the lower insulating support plate 105 is matched with the shape of the front of the inner frame 101. The long sides of the upper insulating support plate 104 and the lower insulating support plate 105 are provided with semi-circular openings. The semi-circular openings of the upper insulating support plate 104 and the lower insulating support plate 105 have the same radius. The shape of the insulating plate 103 is matched with the lower insulating support plate 105. There are multiple insulating plates 103. The insulating plates 103 are fixed between the matching insulating posts 102 in groups of at least two.

[0026] In one possible implementation, the bolted connections of the columnar structure of the inner frame 101 are provided with reinforcing ribs 106, which are right-angled isosceles triangular sheet units.

[0027] Specifically, by setting the reinforcing ribs 106, the structural strength of the bolted connection of the inner frame 101 can be significantly enhanced, the stress concentration at the connection can be effectively dispersed, and the risk of frame deformation caused by long-term use or uneven stress can be reduced, thereby ensuring the overall stability and reliability of the inner frame 101 and extending the service life of the electromagnetic induction coil frame.

[0028] In one possible implementation, the assembly of the upper insulating support plate 104 and the lower insulating support plate 105 further includes a connecting and fixing reinforcing plate 107. The connecting and fixing reinforcing plate 107 is a ring-shaped sheet unit, and the inner diameter of the connecting and fixing reinforcing plate 107 is equal to the radius of the semi-circular opening of the upper insulating support plate 104 and the lower insulating support plate 105.

[0029] Specifically, the connection and fixing reinforcement plate 107 can further strengthen the connection strength at the combination of the upper and lower insulating support plates 104 and 105, making the two more tightly and firmly combined, ensuring the shape accuracy of the semi-circular opening, providing a stable and reliable installation position for the electromagnetic induction coil, preventing the coil from shaking or shifting after installation, and improving the stability and safety of the equipment during operation.

[0030] In one possible implementation, the multiple columnar structures of frame 101 are channel steel. Using channel steel as the columnar structure of the frame, taking advantage of the unique cross-sectional shape and mechanical properties of channel steel, can effectively reduce the overall weight of the frame and lower material costs while ensuring structural strength. Furthermore, the channel-shaped structure of the channel steel facilitates the installation and fixing of other components, improving assembly efficiency, while enhancing the frame's resistance to torsion and bending, enabling the electromagnetic induction coil frame to adapt to complex working environments.

[0031] In one possible implementation, the reinforcing rib 106 is bolted to the inner frame 101. The bolted connection of the reinforcing rib 106 facilitates installation and disassembly, allowing for quick installation or replacement during equipment assembly, maintenance, or repair, thus improving work efficiency. Simultaneously, the bolted connection provides reliable fastening force, ensuring the stability of the connection between the reinforcing rib 106 and the inner frame 101, and ensuring that the reinforcing rib 106 effectively enhances the structural strength.

[0032] Optionally, the reinforcing bolts may be made of copper alloy.

[0033] Optionally, tin bronze can be used as the copper alloy. It has high strength, good friction reduction and corrosion resistance. In the electromagnetic induction coil frame, the reinforcing bolts made of tin bronze can effectively reduce frictional loss between the bolts and the connecting parts while ensuring the tightening force, reducing wear and extending the service life of the bolts; at the same time, thanks to its excellent corrosion resistance, it can work stably in humid or corrosive gas environments, preventing the bolts from rusting and corroding, thus preventing the connection from loosening and ensuring the stability of the frame structure.

[0034] Optionally, aluminum bronze can be used as the copper alloy. Aluminum bronze not only has high strength and hardness, but also excellent wear resistance and fatigue resistance. When used in reinforcing bolts, it can withstand large mechanical stresses and repeated vibrations and impacts, ensuring that the bolt connections remain tight during long-term equipment operation. Furthermore, the good oxidation resistance of aluminum bronze can prevent the bolt surface from reducing connection reliability due to oxidation, making it suitable for electromagnetic induction coil frame applications where high strength and durability are required.

[0035] Optionally, beryllium bronze can be used as the copper alloy. Beryllium bronze possesses high strength, high hardness, and excellent electrical and thermal conductivity. As a reinforcing bolt material, it provides reliable tightening force and quickly conducts heat that may be generated at the bolt connection, preventing localized overheating from affecting bolt performance. Simultaneously, the high conductivity of beryllium bronze helps eliminate static electricity buildup, further reducing the risk of electrical sparks and enhancing the operational safety of the electromagnetic induction coil frame, making it particularly suitable for equipment environments with stringent safety and stability requirements.

[0036] In one possible implementation, the connecting and fixing reinforcing plate 107 is bolted to the upper insulating support plate 104 and the lower insulating support plate 105. Using bolts to connect the upper and lower insulating support plates 104 and 105 and the connecting and fixing reinforcing plate 107 facilitates precise positioning and adjustment during the installation of the electromagnetic induction coil. It also facilitates subsequent disassembly, replacement, or maintenance of the insulating support plates 104 and 105 and the connecting and fixing reinforcing plate 107. The bolted connection ensures a secure connection between components, effectively preventing loosening due to vibration or other factors during equipment operation, thus ensuring the normal operation of the equipment.

[0037] In one possible implementation, the insulating post 102 is made of glass fiber.

[0038] It is possible that the glass fibers of the insulating pillar 102 are stacked in an interleaved manner.

[0039] Specifically, the interlocking stacked glass fiber insulating columns 102 can evenly distribute the stress on the fibers in all directions, effectively improving the overall strength and toughness of the insulating columns 102, making them less prone to breakage or damage when subjected to external forces in different directions; at the same time, the interlocking stacked structure can also enhance the insulation performance of the insulating columns 102, reduce the risk of leakage, and ensure the safety of equipment operation.

[0040] It is possible that the glass fiber of the insulating column 102 is stacked in a spiral winding manner.

[0041] Specifically, the spirally wound stacked glass fiber insulating pillars 102 can form a continuous fiber structure, which greatly improves the tensile and torsional resistance of the insulating pillars 102, enabling them to remain stable under complex mechanical stress environments. Furthermore, this stacking method can optimize the surface flatness of the insulating pillars 102, reduce the problem of local electric field concentration caused by surface unevenness, and further improve the insulation performance.

[0042] It is possible that the glass fiber stacking method of the insulating column 102 is a three-dimensional braided stacking.

[0043] Specifically, the three-dimensional braided stacked glass fiber insulating column 102 has excellent isotropic properties, with high strength and stiffness in multiple directions, which can better adapt to complex and varied stress conditions. At the same time, its unique braided structure helps to improve the bonding between glass fiber and matrix material, enhance the comprehensive performance of insulating column 102, extend the service life of insulating column 102, and ensure the long-term stable operation of electromagnetic induction coil frame.

[0044] In one possible implementation, the insulating plate 103 is made of epoxy resin.

[0045] Optionally, the insulating board 103 is made of epoxy resin with added nano-sized alumina particles. The epoxy resin insulating board with added nano-sized alumina particles can significantly improve the thermal conductivity of the insulating board 103, quickly dissipating the heat generated by the electromagnetic induction coil during operation and preventing coil performance degradation or damage due to heat accumulation. Simultaneously, the addition of nanoparticles can also enhance the mechanical strength and wear resistance of the insulating board 103, improving its service life and reliability.

[0046] Optionally, the insulation board 103 is made of epoxy resin reinforced with carbon fiber. The epoxy resin insulation board reinforced with carbon fiber significantly improves the strength and rigidity of the insulation board 103 while maintaining good insulation performance, enabling it to withstand greater external forces without easily deforming. The addition of carbon fiber also reduces the weight of the insulation board 103, lightening the load on the entire electromagnetic induction coil frame, while improving the fatigue resistance of the insulation board 103 and extending the maintenance cycle of the equipment.

[0047] Optionally, the insulating board 103 is made of epoxy resin with self-healing function. When a micro-crack or damage appears on the surface of the epoxy resin insulating board 103, its internal self-healing mechanism can be automatically activated to repair the damaged area, effectively preventing the crack from expanding further, maintaining the integrity and insulation performance of the insulating board 103; reducing equipment failures caused by damage to the insulating board 103, lowering maintenance costs, and improving the reliability and stability of equipment operation.

[0048] In one possible implementation, an insulating pad 108 is provided at the bottom of the inner frame 101. The shape of the insulating pad 108 matches the bottom surface of the inner frame 101, and the insulating pad 108 is connected to the inner frame 101 by bolts. The insulating pad 108 can effectively isolate the conductive path between the inner frame 101 and the equipment mounting surface, prevent current leakage, and ensure the safe operation of the equipment. At the same time, the insulating pad 108 can also play a role in buffering and shock absorption, reducing the impact of vibration during equipment operation on the electromagnetic induction coil frame, and improving the stability and service life of the frame. In addition, the bolt connection facilitates the installation, disassembly, and replacement of the insulating pad 108, making equipment maintenance and repair convenient.

[0049] In one possible implementation, an insulating outer cover 109 is provided on the inner frame 101. The insulating outer cover 109 covers the top surface and two sides of the inner frame 101. The insulating outer cover 109 is connected to the inner frame 101 and the insulating column 102 by bolts.

[0050] Specifically, the outer cover 109 of the insulating board can provide additional protection for the internal insulating board 103 and other components, effectively blocking external dust, moisture, corrosive substances and other substances from eroding the insulating board 103 and extending the service life of the insulating board 103; at the same time, the outer cover 109 can also enhance the overall protection performance of the electromagnetic induction coil frame and improve the reliability of the equipment in harsh environments; and the bolted connection makes it easy to install and remove the outer cover 109, facilitating the inspection, maintenance and replacement of internal components.
