There is a stirring component, and liquid metal is fed into the vacuum tank 5 through the feed pipe 6. When the liquid metal solidifies, if it is necessary to discharge, water is added to the storage barrel 2 through the water inlet pipe 3, and then heated by the constant temperature electric heating tube 9. The water circulation component circulates water to ensure that the water heats the vacuum tank 5 evenly. The liquid metal will become liquid when it is heated, and then it can be discharged through the discharge pipe 7. The inclined plate 8 can ensure that the liquid metal in the vacuum tank 5 flows to the discharge pipe 7. The stirring component can push the liquid metal on the bottom wall of the vacuum tank 5 to flow, thereby ensuring that all the materials are discharged.

The stirring rod 16 and the stirring plate are both made of plastic.

[0026] In this embodiment, by Figure 1 As shown, the storage barrel 2 is connected with an air pipe 19, and the air pipe 19 is connected with a protective sleeve 20. The protective sleeve 20 is provided with a bellows 21. The protective sleeve 20 and the bellows 21 are sleeved on the outer ring of the discharge pipe 7. In winter or cold weather, the hot air in the heated storage barrel 2 will be sent into the protective sleeve 20 through the air pipe 19, and then sent to the bellows 21 to heat the discharge pipe 7, so as to prevent the discharge pipe 7 from being too low in temperature, causing the liquid metal to solidify too quickly when it is discharged, thereby blocking the discharge pipe 7.
