[0002] Molybdenum has the characteristics of high strength, high hardness, and excellent mechanical properties, and it can still maintain high strength and hardness at high temperatures. Molybdenum is mainly used in steelmaking. Alloy steel mixed with molybdenum has high strength, high toughness, outstanding heat resistance and corrosion resistance. Metal molybdenum is widely used in electronic devices such as electron tubes, transistors, rectifiers, etc.

[0003] Molybdenum metal products are made by adding molybdenum to the original metal, and then smelting and mixing it to make it evenly distributed inside the original metal. When molybdenum is mixed with metal, both are usually in a metal liquid state at high temperature to facilitate mixing. Since molybdenum has a high melting point, the furnace needs to be kept in a sealed state to ensure sufficient temperature. Usually after the two metals are melted, the impurities in the metal solution need to be removed to avoid impurities still existing in the alloy after cooling. The traditional mixed liquid metal is filtered, and the furnace needs to be opened, resulting in a decrease in the air tightness of the furnace, which will lead to a decrease in temperature.

[0022] By storing the metal block in the storage tank 2, connecting it with the smelting tank 1 through the leak hole 5, the metal block inside is heated to be melted, and the impurities inside the metal are filtered by the movable cylinder 4 and cannot flow into the smelting tank 1, so the impurities are separated in advance. When the molybdenum metal and other metals are in liquid state in the smelting tank 1, the storage tank 2 is driven by the driving motor 92 to rotate the stirring blade 10 to stir and mix the liquid metal, so as to avoid uneven distribution of the molybdenum metal due to temperature reduction.

[0023] The driving assembly 9 includes a fixing frame 91 fixed to the top of the smelting tank 1, a driving motor 92 is fixed to the top of the fixing frame 91, an output shaft of the driving motor 92 passes through the fixing frame 91 and is fixed with a driving gear 93, a driven gear 94 is fixed to the outside of the storage tank 2, the driving gear 93 is meshed with the side facing the driven gear 94, the driving motor 92 installed on the top of the fixing frame 91 drives the driving gear 93 to rotate, and then the storage tank 2 is driven by the driven gear 94, so that the storage tank 2 rotates together with the stirring blade 10 in the smelting tank 1, and the stirring blade 10 is used to stir and mix the liquid metal inside the smelting tank 1 to ensure uniform distribution of the molybdenum metal.

[0024] The inner cavity of the storage tank 2 is provided with a limiting groove 11, and the inner cavity of the limiting groove 11 is slidably connected with a limiting block 12 fixed to the outer side of the movable cylinder 4. The limiting block 12 slides in the inner cavity of the limiting groove 11 to limit the movable cylinder 4 and prevent the movable cylinder 4 from rotating inside the storage tank 2, causing the position of the movable side plate 7 and the window 6 to be misaligned, and the movable side plate 7 cannot penetrate the window 6 to discharge the impurities inside.

[0025] A collecting frame 13 is fixed on the top of the smelting pot 1 , and the collecting frame 13 is sleeved on the outside of the storage pot 2 . The impurities discharged from the movable cylinder 4 can be collected through the collecting frame 13 to prevent high-temperature impurities from flowing outward along the top of the smelting pot 1 .

At the same time, the liquid metal inside the smelting tank 1 can be discharged from the smelting tank 1 through the liquid outlet pipe 17.

[0029] When used specifically, the smelting tank 1 is heated by a heating device, and then the metal block is added into the movable cylinder 4 from the top of the storage tank 2. The storage tank 2 is connected to the smelting tank 1 through the discharge hole 3. The metal block is heated in the movable cylinder 4 and then gradually melts. When the metal block melts, it flows into the smelting tank 1 along the leakage hole 5 and the discharge hole 3. Then, the molybdenum metal block is added into the storage tank 2. The molybdenum metal is heated and liquefied and flows into the smelting tank 1. Impurities in the metal that cannot be melted are filtered in the movable cylinder 4. The movable cylinder 4 is pulled upward by the traction rope 14. When the movable cylinder 4 moves After reaching the window 6 position, the movable side plate 7 is supported outward by the support spring 8 to extend outward from the window 6, and then the impurities remaining in the movable cylinder 4 are discharged from the storage tank 2 along the movable side plate 7 and flow into the collection frame 13, and the drive motor 92 is started, and the drive motor 92 drives the drive gear 93 to rotate, and then the drive gear 93 drives the driven gear 94 to drive the storage tank 2, and the storage tank 2 drives the stirring blade 10 to stir and mix the liquid metal inside the smelting tank 1. Since the inside of the smelting tank 1 is continuously in a high temperature state, the molybdenum metal can be well distributed inside other metals.
