When the smelting furnace 3 finishes pouring the aluminum liquid, the electromagnet controller 7 controls the introduction of a reverse current into the electromagnet block 104. At this time, the magnetic poles of the end of the convex plate 101 and the electromagnet block 104 that are close to each other are opposite, and the electromagnet block 104 and the permanent magnet block 103 The attraction action drives the shaft rod 6 to rotate and reset, thereby pushing the smelting furnace 3 to reset and flip, so that the smelting furnace 3 is automatically reset. The smelting furnace 3 is easy to reset, simple in structure, low in use and maintenance costs, and strong in practicality.

[0027] Further as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, it is worth specifically explaining that the heat exhaust component 2 includes a joint tube 203 fixed on the end of the feeding tube 11, a ventilation cavity 201 is opened in the side wall of the joint tube 203, and a blowing hole 202 connected to the ventilation cavity 201 is opened on the inner wall of the joint tube 203, and the blowing hole 202 is provided with a plurality of holes 202 and the plurality of holes 202 are distributed in a ring shape, and an air supply hose 204 is fixed on the output end of the air pump 5, and the end of the air supply hose 204 away from the air pump 5 is connected to the ventilation cavity 201; when the top end port of the feeding tube 11 is opened to add raw materials, The cold air in the external environment is sucked in by the air pump 5 and transported to the inside of the ventilation chamber 201 through the air supply hose 204, and the cold air is blown out to the top end port of the feeding tube 11 through multiple blowing holes 202, thereby cooling the top end port of the feeding tube 11.

When the aluminum liquid in the smelting furnace 3 is dumped, the electromagnetic controller 7 controls the reverse current to be passed into the electromagnetic block 104. At this time, the magnetic poles of the end of the convex plate 101 and the electromagnetic block 104 that are close to each other are opposite. The electromagnetic block 104 and the permanent magnet block 103 are attracted to each other to drive the shaft rod 6 to rotate and reset, thereby pushing the smelting furnace 3 to reset and flip, so that the smelting furnace 3 is automatically reset, and the top port of the feeding pipe 11 is opened for When adding raw materials, cold air is sucked from the external environment through the air pump 5 and transported to the inside of the ventilation chamber 201 through the air supply hose 204, and the cold air is evenly and finely blown out to the top end port of the feeding tube 11 through multiple blowing holes 202, so as to cool the top end port of the feeding tube 11. The cold air dissipates and cools the hot air ejected from the inside of the feeding tube 11, thereby reducing the hot air inside the smelting furnace 3 from being sprayed to the outside through the port of the feeding tube 11, thereby reducing the contact between the human body and the hot air when the workers add raw materials.

[0029] Further as Figure 5 As shown, it is worth explaining in detail that the multiple blowing holes 202 are arranged to be inclined upward; during specific operation, the cold air is blown toward the port of the feeding tube 11 through the blowing holes 202 arranged to be inclined upward, thereby improving the cooling effect at the port of the feeding tube 11.

When the smelting furnace 3 has finished pouring the aluminum liquid, the conversion component 1 applies a reverse magnetic force to the shaft rod 6, thereby pushing the smelting furnace 3 to reset and flip, so that the smelting furnace 3 is automatically reset. The smelting furnace 3 is easy to reset, has a simple structure, low use and maintenance costs, and is highly practical. When the top port of the feeding pipe 11 is opened to add raw materials, the air pump 5 is used. The cold air in the external environment is sucked in and transported to the inside of the heat exhaust component 2, and the cold air is evenly and finely blown out into the top end port of the feeding tube 11 through the heat exhaust component 2, so as to cool the top end port of the feeding tube 11. The cold air disperses and cools the hot air ejected from the inside of the feeding tube 11, effectively reducing the hot air inside the smelting furnace 3 from being sprayed to the outside through the port of the feeding tube 11, effectively reducing the contact between the human body and the hot air when the workers add raw materials, improving the protection of the workers, and improving the safety of the use of the smelting furnace 3.
