The reaction chamber and the feeding chamber are separated by an electric control door, and when vacuuming, the reaction chamber and the feeding chamber can be vacuumed separately. When feeding the feeding chamber, the electric control door can be closed to ensure the vacuum degree in the reaction chamber, and then the feeding chamber is vacuumed. After the feeding chamber is in a vacuum state, the electric control door can be opened to add materials, so that the feeding can be operated continuously without affecting the heating process.

[0004] However, the above-mentioned vacuum induction furnace still has the following problems:

[0005] The above-mentioned vacuum induction furnace adds a charging bin, in which materials are added so that the charging can be operated continuously without affecting the heating process. However, during the operation of the vacuum induction furnace, the metal is heated to the required temperature by induction heating. Therefore, the temperature inside the vacuum induction furnace will be relatively high. Because there is no equipment for rapid cooling in the charging bin, when opening the charging bin to add items, it is necessary to wait for a long time after closing the electric control door, and then fill the material after the temperature inside the charging bin drops, thereby wasting a long time and reducing work efficiency.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1-Figure 4 A vacuum induction furnace for vacuum metallurgy comprises an induction furnace body 1, an electric control door 8 installed on the induction furnace body 1 and a charging bin 2, the electric control door 8 is located between the induction furnace body 1 and the charging bin 2, a condensing plate 9 is fixedly connected to the inner wall of the charging bin 2, a cooling cavity 901 is opened on the inner wall of the condensing plate 9, a cooling box 3 is fixedly connected to the upper surface of the induction furnace body 1, a cooling mechanism is connected to the inner wall of the cooling box 3, a circulation component is connected to the output end of the cooling mechanism, the other end of the circulation component passes through the outer walls of the cooling box 3, the charging bin 2 and the condensing plate 9, and after passing through the inner wall of the cooling cavity 901, it passes through the condensing plate 9, the charging bin 2 and the outer walls of the cooling box 3 again.

[0023] The vacuum induction furnace for vacuum metallurgy in the utility model is similar in structure to the existing vacuum induction furnace for vacuum metallurgy, such as the vacuum induction furnace disclosed in the patent with publication number CN217844701U. The main improvement of the utility model is that when the user is loading materials through the charging bin 2, the cooling mechanism and the circulation component can be used in conjunction with the condensation plate 9 to cool the inside of the charging bin 2 in advance, so that the materials can be loaded quickly. Figures 1 to 4As shown, before the vacuum induction furnace for vacuum metallurgy in the utility model is used, the material is first placed inside the induction furnace body 1, and then vacuuming and heating are started. During the heating period, if it is necessary to load materials, the charging bin 2 and the induction furnace body 1 are first separated by the electric control door 8 to maintain the vacuum and high temperature inside the induction furnace body 1, and then the switch of the cooling mechanism is turned on by the external controller. After the cooling mechanism is started, the coolant inside the cooling box 3 will be transported to the inside of the circulation component. Because the circulation component is located in the cooling chamber 901, the condensation plate 9 can be cooled through the cooling chamber 901, and then the heat exchange between the condensation plate 9 and the charging bin 2 will be used to transport the heat in the charging bin 2 back to the cooling box 3 through the circulation component for cooling and subsequent circulation. Through the above steps, the inside of the charging bin 2 can be cooled more quickly, and then the material can be loaded quickly. It is worth mentioning here that the external controller is a very mature technology in the prior art, so it is not described in detail.

[0024] Please refer to Figure 4 The cooling mechanism includes a base 11 and a cooling pump 12. The bottom surface of the base 11 is fixedly connected to the bottom surface of the inner wall of the cooling box 3. The outer wall of the cooling pump 12 is fixedly connected to the other side of the base 11. The output end of the cooling pump 12 is connected to the circulation component.

[0025] More specifically, when the inside of the charging bin 2 needs to be cooled, the switch of the cooling pump 12 is turned on by an external controller. After the cooling pump 12 is started, it maintains stable operation under the support of the base 11, and then the coolant inside the cooling box 3 can be transported to the inside of the circulation component.

[0026] Please refer to Figure 3 and Figure 4 The circulation component includes a reflux pipe 6, a liquid outlet pipe 13 and a circulation pipe 14. One end of the liquid outlet pipe 13 is fixedly connected to the output end of the cooling pump 12. The other end of the liquid outlet pipe 13 passes through the cooling box 3, the feeding bin 2 and the condensation plate 9, and is fixedly connected to one end of the circulation pipe 14. The other end of the circulation pipe 14 passes through the cooling chamber 901 and is fixedly connected to one end of the reflux pipe 6. The other end of the reflux pipe 6 passes through the condensation plate 9, the feeding bin 2 and the cooling box 3. The reflux pipe 6 and the liquid outlet pipe 13 are both fixedly connected to the penetration point of the condensation plate 9, the feeding bin 2 and the cooling box 3.

[0027] More specifically, when the cooling pump 12 transports the coolant inside the cooling box 3 to the liquid outlet pipe 13, the coolant inside the liquid outlet pipe 13 then enters the circulation pipe 14, and then the coolant inside the circulation pipe 14 will be transferred by the feeding bin 2 to the hot gas adsorption in the cooling chamber 901, and then flow back to the cooling box 3 through the reflux pipe 6 again, and after being cooled by the cooling box 3, it will be provided for subsequent circulation.

[0028] Please refer to Figure 3 and Figure 4 The lower end of the inner side of the condensation plate 9 is fixedly connected with a water collecting plate 10, and the bottom surface of the water collecting plate 10 is fixedly connected with a drain pipe 7. The other end of the drain pipe 7 passes through the condensation plate 9 and the feeding bin 2, and is fixedly connected to the penetration point of the condensation plate 9 and the feeding bin 2. A valve is provided at one end of the drain pipe 7 passing through the condensation plate 9 and the feeding bin 2.

[0029] More specifically, because the temperature in the charging bin 2 is very high, and the condensation plate 9 is relatively cool due to the effect of the circulation pipe 14 and the coolant, the condensation plate 9 at this time is likely to produce water droplets due to the contact between hot and cold during use. At this time, these water droplets can slide along the outer wall of the condensation plate 9 to the water collecting plate 10 below, and then be discharged to the outside through the drain pipe 7; and it is worth mentioning here that: when vacuuming, the drain pipe 7 can be sealed by a valve to avoid air leakage and the like.

[0030] Please refer to Figure 1-Figure 4 The upper surface of the cooling box 3 is fixedly connected with a liquid adding pipe 4, and the inner wall of the liquid adding pipe 4 is threadedly connected with a sealing cap 5. By providing the liquid adding pipe 4 and the sealing cap 5, when the coolant in the cooling box 3 is about to run out, it can be added through the liquid adding pipe 4, and when it is not needed, it can be sealed through the sealing cap 5.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
