[0002] The medium frequency furnace is an important tool for modern metallurgy and plays an important role in the development of metallurgy and materials. The medium frequency furnace uses coil induction heating, and the coil is sealed with an alumina or magnesia sand crucible. The metal is melted in the sealed crucible. This method of melting metal has the characteristics of fast heating, less alloy burnout, and precise control of alloy composition.

[0003] The electric furnace charging car is a vibration charging device specially designed and developed for smelting electric furnaces. It adopts vibration charging method, which is easy to use, stable charging, can reduce the impact of material blocks on the furnace body to the minimum, and the charging is more in line with the process requirements.

[0004] Patent No. CN202393235U discloses a post-furnace charging device for an electric furnace, including a feeding cart, on which a material box is hinged. Materials enter the material box through a material inlet on the upper side of the material box. The material box moves with the feeding cart to feed materials. The material box is driven by the material box driving mechanism to rotate along the front end of the feeding cart, so that the material is discharged from the material outlet, reducing the operation of manual feeding into the electric furnace and improving the convenience of feeding.

[0005] However, since the feeding port of the medium frequency furnace is located at a high position, the height of the feeding cart is also high, which makes it difficult for operators to put the alloy into the feeding cart. Manual handling is required, which leads to high labor intensity and affects production efficiency. In addition, during the feeding process of the feeding cart, the alloy falls into the medium frequency furnace at a fast speed as the material box is turned over, and it is easy to collide with the medium frequency furnace, thereby affecting the service life of the medium frequency furnace and increasing the production cost of repairing the medium frequency furnace. Summary of the invention

[0006] The purpose of the present invention is to provide an alloy adding device for a medium frequency induction furnace. A lifting mechanism is provided to lift a feeding barrel, and the feeding barrel is driven to add material by a flipping mechanism, so that an operator can quickly add material to a feeding cart, and a material guiding mechanism is provided at the end of a bottom plate. When the feeding cart adds material to the medium frequency furnace, the material guiding mechanism guides the material to reduce the falling distance, and a material blocking mechanism is used to block and buffer the sliding material, thereby reducing the impact force of the falling material, making the material fall more smoothly, thereby reducing collisions, and solving the problems in the background technology that it is difficult to add material to the feeding cart and that adding material to the feeding cart easily causes the material to collide and be damaged by the medium frequency furnace.

[0010] A further improvement is that baffles are provided on the sides of the bottom plate and the material guide plate, and a buffer pad is provided on the surface of the bottom plate.

[0014] Beneficial effects of the present invention: 1. The present invention sets a bottom plate in the charging vehicle, and the bottom plate is driven by a lifting cylinder to flip along the rotating shaft, so that the material slides along the inclined surface of the flipped bottom plate for feeding, and a guide plate is set at the end of the bottom plate, and the guide plate extends into the medium frequency induction furnace during feeding, thereby increasing the distance the material slides, reducing the height of the material feeding, and reducing collision; the existing ones all set a material box next to the electric furnace, and the material is fed into the electric furnace through the flipping and sliding of the material box, and the feeding height is high when the material is fed above the electric furnace, and the material is easy to collide with the equipment, and there is a gap between the material box and the electric furnace, which causes the material to fall into the gap, thereby affecting the feeding effect. The present application sets a guide plate, and the guide plate expands and contracts with the flipping of the bottom plate, and extends and extends into the medium frequency induction furnace during feeding, so that the material can be fed more stably, which greatly improves the feeding effect.

When the bottom plate 5 is flipped upward and tilted, the material guiding plate 11 slides and shrinks into the slide groove 12 due to its own gravity; when the bottom plate 5 is flipped downward, the material guiding plate 11 slides out of the slide groove 12 due to its own gravity, so that the material guiding plate 11 extends into the medium-frequency induction furnace 1, and the material slides along the material guiding plate 11 into the medium-frequency induction furnace 1, reducing the sliding height, thereby reducing collision.

[0026] A material blocking mechanism is provided at one end of the feeding trolley 4, and the material blocking mechanism includes a material blocking plate 14; one end of the feeding trolley 4 is opened, and the material blocking plate 14 is set at the open end of the feeding trolley 4 by rotating the rotating shaft. When the material slides from the bottom plate 5 through the open end of the feeding trolley 4 to feed, the material blocking plate 14 blocks the material, and the material pushes the material blocking plate 14 to rotate along the rotating shaft due to its own gravity, thereby reducing the impact force of the material when it slides down during feeding, thereby reducing the collision between the material and the equipment.

[0027] Baffles 13 are provided on the sides of the bottom plate 5 and the guide plate 11, and the baffles 13 on both sides are used to guide the materials sliding down on the bottom plate and the guide plate 11 to prevent the materials from falling from the sides and affecting the feeding; a buffer pad is provided on the surface of the bottom plate 5, and the buffer pad is used to buffer when adding materials into the opposite feeding cart 4, thereby reducing the impact of the materials on the feeding cart 4, thereby improving the service life of the feeding cart 4.

[0030] A weighing machine 6 is provided on the side of the feeding platform 2, and the material in the feeding barrel 8 is weighed by the weighing machine 6, so as to accurately control the feeding amount.

[0031] In actual production and use, the staff places the feeding bucket 8 on the weighing machine 6, and then places the alloy material in the feeding bucket 8. The weighing machine 6 weighs the alloy material in the feeding bucket 8 to accurately control the weight of the alloy material added. The controller controls the traction machine 15 to drive the traction rope 16 to lift the weighed feeding bucket 8 to the top of the feeding cart 4 through the hook. The feeding bucket 8 is turned over by the turning motor 7, and the weighed alloy material is poured into the feeding cart 4. The buffer pad on the bottom plate 5 buffers the addition of the alloy material to reduce collision. After the material is added, the driving motor drives the feeding cart 4 to move on the slide rail 3; when it moves to the position, the lifting cylinder 10 lifts one end of the bottom plate 5, and the bottom plate 5 flips along the rotating shaft 9.
