Description

Technical Field

[0001] The utility model relates to the technical field of electric melting furnace charging, in particular to an electromagnetic charging device for an electric melting furnace. Background Art

[0002] An electric melting furnace is a device that uses electric energy to heat metal or alloy materials to their melting point for recycling or further processing. In an electric melting furnace, electrical energy is converted into thermal energy through resistance, and the metal or alloy material is heated to its melting point, turning it into a liquid state. The heating medium of the electric melting furnace is mainly induction current and resistance heating. The temperature of the electric melting furnace can reach very high, and some electric melting furnaces can be heated to above 3000℃.

[0003] Electric furnaces need to be fed with materials during production. After searching, it was found that the publication number is CN219885909U, and the name is a feeding device for electric furnaces. The application proposed a utility model patent with patent publication number CN216808562U. A weighing device is provided, and the weighing device is located directly below the feed bin so as to know the weight of the feed and facilitate accurate feeding. A push plate and a push head are respectively provided on the left and right sides of the feeding chamber. The push head is driven by a cylinder, and the push plate is connected by a spring, which is conducive to the opening and closing of the discharge process. Although this method can feed accurately, it also has the problem of insufficient processing continuity due to the structural setting of the single-group pushing device, thereby reducing the overall processing efficiency. The rotating shaft is driven by the motor. Rotate so that the feed box is facing the bottom of the feed hopper, and the material is manually put from the feed hopper into the feed box, and the weight information is transmitted to the display through the weighing platform. After the weight is reached, the feeding is stopped, and the feed box is rotated again to make the internal material fall into the furnace from the discharge port. However, there are large gaps between the feed boxes. When rotating to feed, the raw materials inside the feed hopper will fall through the gaps between the feed boxes, affecting the stability of the feeding. At the same time, the feed box will also scatter raw materials during the rotation process, resulting in inaccurate addition, affecting the use efficiency. In addition, when the particle size of the raw materials inside the feed hopper is small, it is easy to produce a bridging effect, resulting in poor discharge, affecting the continuity and stability of the work, and further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

When feeding, the raw materials in the hopper 2 pass through the connecting cloth sleeve 7 into the feeding tube 1 and into the material trough 13. The stepper motor 9 drives the roller shaft 15 to rotate and then drives the roller 12 to rotate, and then drives the material trough 13 to rotate, and the raw materials in the material trough 13 are thrown out of the discharge port 1 0, for uniform quantitative feeding. When the roller 12 rotates, the outer wall of the sealing gasket 14 slides and abuts against the inner wall of the feeding barrel 1 to avoid leakage of raw materials, improve the uniformity and stability of feeding, and thus improve work efficiency. At the same time, the electromagnetic exciter 6 vibrates the hopper 2 during feeding to reduce the phenomenon of raw material blockage, improve the smoothness of feeding, facilitate the raw material to quickly fill the trough 13, and ensure the stability of uniform feeding. At the same time, the connecting cloth sleeve 7 avoids transmitting the vibration to the feeding barrel 1, avoids affecting the stability, and further improves the use efficiency.
