[0031] The input end of the heating device 13 is fixedly connected to the exhaust pipe 12; the other end of the exhaust pipe 12 is fixedly connected to the bottom surface of the outer tank body 1 and communicates with the interior of the outer tank body 1; the output end of the heating device 13 is fixedly connected to the intake pipe 19; the intake pipe 19 is communicated with the interior of the second shell 11; the intake pipe 19 corresponds to the bottom end of the rotating tube 5.

[0032] A groove 20 is provided on the bottom surface of the inner tank body 8 at a position corresponding to the interior of the second shell body 11; a plurality of connection holes 21 are evenly provided on the side walls of the groove 20; the connection holes 21 are all connected to the interior of the constant temperature chamber 9; a plurality of exhaust pipes 4 are evenly fixedly connected to the upper end surface of the inner tank body 8 at a position corresponding to the constant temperature chamber 9; the bottom ends of the exhaust pipes 4 are all connected to the interior of the constant temperature chamber 9; and the other ends of the exhaust pipes 4 are all connected to the outside.

[0035] Working principle:

[0036] When in use, the casting liquid is injected into the inner tank body 8 through the injection pipe 2. When the injection is completed, the heating device 13 is started, and the hot air generated by the casting liquid rises and enters the first shell 7. In the process of the hot air entering the first shell 7, the hot air will blow the first fan blade 6 to rotate, and the first fan blade 6 will drive the rotating tube 5 to rotate. The rotation of the rotating tube 5 drives the stirring rod 17 to rotate, and the stirring rod 17 rotates to stir the casting liquid.

[0037] Then the hot air enters the cavity formed by the outer tank body 1 and the inner tank body 8 through the exhaust hole 18, thereby heating the cavity formed by the outer tank body 1 and the inner tank body 8. During this process, the heating device 13 will draw the hot air in the outer tank body 1 into the heating device 13 through the exhaust pipe 12, and the temperature of the hot air will be increased by the heating device 13. The heated hot air is then sent into the second shell 11 through the air inlet pipe 19, and the hot air in the second shell 11 enters the connecting hole 21 and the rotating tube 5.

[0038] The hot air entering the connection hole 21 will enter the constant temperature chamber 9, thereby completing the heating of the inner tank body 8, thereby improving the heat preservation effect. The hot air in the constant temperature chamber 9 will eventually be discharged to the outside through the exhaust pipe 4.

[0039] The hot air entering the rotating tube 5 will enter the stirring rod 17, thereby heating the inside of the casting liquid. Finally, the hot air in the rotating tube 5 will be discharged to the outside. When the heating device 13 sends the hot air to the second shell 11 through the air inlet pipe 19, the hot air will blow the second blade 14, thereby causing the second blade 14 to rotate. The rotation of the second blade 14 drives the rotating tube 5 to rotate, thereby driving the stirring rod 17 to rotate; and under the action of the stirring rod 17, the temperature in the casting liquid is made more balanced.

[0040] It should be noted that the hot air blows the second fan blade to rotate and then drives the rotating tube 5 to rotate as the main driving mode; the hot air in the inner tank body 8 rises and blows the first fan blade 6 to rotate, and the first fan blade 6 drives the rotating tube 5 to rotate to play an auxiliary driving role.

Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
