Description

Technical Field

[0001] The utility model relates to the technical field of vacuum furnaces, in particular to an automatic raw material adding structure for a smelting furnace. Background Art

[0002] In the field of vacuum melting furnaces, the current method of feeding vacuum melting furnaces is to add all the raw materials to be melted into the system at one time, and no additional feeding is required during the entire melting process, so as to ensure that the vacuum degree of the system is not affected; if this method requires feeding, the vacuum degree of the entire device needs to be destroyed, continuous production cannot be achieved, and the production efficiency is relatively low.

[0003] In the process of adding raw materials, how to achieve uninterrupted continuous feeding without repeatedly destroying the vacuum environment is an important factor affecting production efficiency and production cost. In the past, the raw material adding mechanism of the vacuum melting furnace could only add one raw material adding cylinder at a time. It took about 3-4 repeated additions to add a full amount of dissolved material. It was necessary to manually hook the raw material adding cylinder to repeatedly destroy the vacuum environment of the raw material adding chamber during the lifting and lowering. The vacuum had to be repeatedly extracted during the adding process, which was costly and inefficient. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a structure for automatically adding raw materials to a smelting furnace, which solves the problems of the prior art in which vacuum must be repeatedly drawn during the adding process, resulting in high cost and low efficiency.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a raw material automatic adding structure of a smelting furnace, including a raw material adding vacuum shell, and the technical key points are: a rotating bracket is arranged in the raw material adding vacuum shell, a plurality of raw material barrels are arranged on the rotating bracket, an active grabbing and releasing device is arranged above the rotating bracket, and a hoisting lifting mechanism is connected above the active grabbing and releasing device;

[0006] A gate valve and a coil crucible are arranged in sequence below the rotating support, and the active grabbing and releasing device grabs any raw material barrel in the rotating support and places it in the coil crucible (11);

[0007] An automatic door opening and closing mechanism and a translational rotating lifting trolley are sequentially arranged on one side of the rotating bracket.

[0008] Preferably, a reduction motor is connected below the rotating shaft of the rotating bracket, and the reduction motor is used to drive the rotating shaft of the rotating bracket to rotate.

[0009] Preferably, a track is provided below the translational rotary lifting trolley, a reducer is connected below the track, and the reducer is used to drive the translational rotary lifting trolley to move on the track.

[0010] Preferably, the raw material cylinder is made of pure iron.

[0011] Preferably, the number of the raw material barrels is four to six.

[0012] The beneficial effects of the utility model are as follows: the utility model protects an automatic raw material adding structure for a smelting furnace, which realizes automatic rotating feeding by increasing the volume of the raw material adding vacuum shell and setting the rotating bracket inside the vacuum chamber, and the raw material barrel can be automatically grabbed and released, thereby improving work efficiency. At the same time, since the raw materials that need to be added to the NdFeB magnetic material during the smelting process include pure iron, the original repeatedly used raw material barrel is made of pure iron, and other raw materials are added to the barrel. Through the active grabbing and releasing device, the raw material barrel is added to the coil crucible in the furnace for smelting, which saves the maintenance and use of the raw material barrel and improves efficiency.
