[0031] As an embodiment of the present application, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The stirring heat dissipation mechanism 5 comprises a motor 51, a disc 52 and stirring rods 53, the middle part of the lower end of the furnace body 1 is fixedly connected with the motor 51 through a frame plate, the output shaft of the motor 51 extends upward to the inside of the furnace body 1, the top end of the output shaft of the motor 51 is fixedly connected with the disc 52, a plurality of groups of stirring rods 53 are fixedly connected on the upper end surface of the disc 52 in a ring shape at equal intervals, an inductor 54 is fixedly connected with the left side of the disc 52 on the bottom of the furnace body 1, high-temperature-resistant paint is sprayed on the outer surface of the inductor 54, a box body 56 is placed in the inside of the four groups of supports 11 on the bottom of the furnace body 1, the material of the box body 56 is transparent glass, a water injection pipe 562 is fixedly connected with the left side of the upper end of the box body 56, an air outlet pipe 563 is fixedly connected with the right side of the upper end of the box body 56, a copper disc plate 55 is arranged between the furnace body 1 and the box body 56, a plurality of groups of copper rods 551 are fixedly connected with the lower end surface of the copper disc plate 55 in a ring shape at equal intervals, the plurality of copper rods 551 all extend downward to the inside of the box body 56 and are slidably connected with the box body 56, electromagnetic blocks 561 are fixedly connected with the left and right sides of the upper end surface of the box body 56 and the lower end surface of the copper disc plate 55, a steam generator 57 is fixedly connected with the top end of the air outlet pipe 563, a compressor is fixedly connected between the air outlet pipe 563 and the steam generator 57, and an accumulator 58 is fixedly connected with the right side of the steam generator 57.

[0032] By adopting the scheme, when the aluminum alloy solution pours into the inside of the furnace body 1, the power of the motor 51 is turned on, the output shaft of the motor 51 drives the disc 52 to rotate, and when the disc 52 rotates, the several groups of stirring rods 53 on the disc 52 stir the aluminum alloy solution in the inside of the furnace body 1, so as to prevent segregation phenomenon due to uneven temperature in the metal solution, and to affect the product quality. When the furnace body 1 is in the process of heat preservation and the temperature in the inside of the furnace body 1 exceeds a certain temperature value due to the overlong power-on time of the coil 33, the inductor 54 will make induction and control the external power to supply power to the four groups of electromagnetic blocks 561 and stop supplying power to the coil 33. In the initial state, the upper and lower two groups of electromagnetic blocks 561 on the left and right sides are in the state of adhesion. After power-on, due to the principle of repulsion between same magnetic forces, the copper disc plate 55 will move upward and finally adhere to the lower end face of the furnace body 1. Since the temperature of the aluminum alloy solution is as high as more than 600 degrees, the high temperature in the furnace transfers the temperature of the furnace bottom to be also high. Since the melting point of copper is more than 1,000 degrees, and the heat conduction performance is good, when the copper disc plate 55 contacts the furnace bottom, most of the heat of the furnace bottom can be transferred to the inside of the box body 56 through the copper rod 551. In the initial state, the inside of the box body 56 is filled with liquid water. When the high temperature is transferred to the inside of the box body 56, the water will boil and evaporate to produce water vapor. Since the evaporation absorbs heat, when the water in the inside of the box body 56 evaporates, the heat transferred from the furnace bottom to the copper disc plate 55 will be consumed, so as to reduce the heat in the inside of the furnace body 1 and avoid the continuous temperature rise to cause the oxidation of the aluminum alloy solution. Since the inside of the water injection pipe 562 is provided with a one-way valve, the steam in the inside of the box body 56 can only flow out through the air outlet pipe 563. When this part of low-pressure steam passes through the compressor, it will become high-pressure steam and finally enter the inside of the steam generator 57 to participate in the power generation work. Since the material of the box body 56 is transparent glass, when the water amount in the inside of the box body 56 is reduced too much, water can be supplemented to the inside of the box body 56 through the water injection pipe 562. The power generated by the steam generator 57 will be stored in the storage battery 58, and the storage battery 58 can provide power for the device. The device makes full use of the excess heat energy and is more energy-saving and environment-friendly.

[0033] Working principle: when there is aluminum alloy solution to pour into the furnace body 1 inside the heat preservation, open the power supply to the coil 33 power, make the coil 33 inside the alternating current, thus generating alternating magnetic field, the ceramic rod 32 inside the coil 33 can make the alternating magnetic field produce eddy current and achieve the effect of heating, in this way to the inside of the furnace 1 preheating, while the coil 33 power supply, the electric spring 23 also power supply, four groups of electric spring 23 after power supply, the four groups of plug rod 24 will be displaced upward and finally inserted into the slot in the block two 21, to play a certain fixed clamping effect, prevent the furnace cover 13 from deviating when pouring aluminum alloy solution, then open the top cover 43 on the upper end of the feed hopper 41, the top cover 43 has two kinds of opening and closing mode, one is to move the top cover 43 left and right to make the strut 42 rotate and make the top cover 43 rotate and slide on the upper end of the feed hopper 41, this way can control the size of the feed inlet while reducing the heat loss in the furnace, the other is to control the top cover 43 to flip up and open the feed inlet, this way will completely open the feed inlet for easy feeding, when pouring aluminum alloy solution, you can choose different ways to open the top cover 43 according to the actual situation, when the aluminum alloy solution enters the furnace body 1 inside, you can heat preservation, heat preservation shell 35 can reduce the temperature loss in the furnace and increase the heat preservation effect of the furnace body 1, when the aluminum alloy solution is poured into the furnace body 1, open the power supply of the motor 51, the output shaft of the motor 51 drives the disc 52 to rotate, when the disc 52 rotates, the disc 52 on the several groups of stirring rod 53 on the disc 52 to stir the aluminum alloy solution in the furnace body 1, prevent the segregation phenomenon due to uneven temperature in the metal solution, to affect the product quality, when the furnace body 1 in the process of heat preservation due to the coil 33 power supply time too long, resulting in the temperature in the furnace 1 exceeds a certain temperature value, the inductor 54 will make the induction and control the external power supply to the four groups of electromagnetic block 561 power supply and stop power supply to the coil 33, the initial state of the upper and lower two groups of electromagnetic block 561 on both sides is in the state of adhesion, after power supply, due to the principle of repulsion between the same magnetic force, the copper disc plate 55 will move upward and finally adhere to the lower end surface of the furnace body 1, due to the high temperature of the aluminum alloy solution up to six hundred degrees, the high temperature transfer in the furnace makes the furnace bottom temperature is also higher, due to the melting point of copper is more than one thousand degrees, and good thermal conductivity, so when the copper disc plate 55 contacts with the furnace bottom, most of the heat of the furnace bottom can be transferred to the box 56 inside through the copper rod 551, the initial state of the box 56 is filled with liquid water, when the high temperature is transferred to the box 56 inside, the water will boil and evaporate to produce water vapor, due to the heat absorption of evaporation, when the water in the box 56 evaporates, the heat transferred from the furnace bottom to the copper disc plate 55 will be consumed, thus reducing the heat in the furnace body 1, to avoid the continuous rise of temperature and make the aluminum alloy solution oxidation, because the water injection pipe 562 is provided with a check valve, the steam in the box 56 can only flow out through the exhaust pipe 563, when this part of low pressure steam passes through the compressor, it will become high pressure steam and finally enter the steam generator 57 to participate in the power generation work, because the material of the box 56 is transparent glass,When the water in the box 56 is reduced too much, water can be added to the box 56 through the water injection pipe 562, and the electricity generated by the steam generator 57 can be stored in the battery 58, which can provide power for the device, fully utilize the excess heat energy, and make the device more energy-saving and environmentally friendly.
