[0019] It should be noted that, since the heat dissipation tube in the prior art is open, a large amount of dust is generated when the equipment is working, causing pollution to the surrounding environment. Therefore, in order to solve the problem that the heat dissipation tube in the prior art is open, a large amount of dust is generated when the equipment is working, causing pollution to the surrounding environment, the casting sand of this solution enters the heat dissipation tube 2 through the feed hopper 3, and the high-pressure air pump 9 works to increase the air pressure at the bottom of the heat dissipation tube 2. The air at the upper end of the heat dissipation tube 2 is extracted by the exhaust fan 11, thereby generating upward air circulation in the heat dissipation tube 2. By increasing the amount of dust, the heat dissipation tube 2 is cooled and the heat dissipation tube 2 is cooled, the heat dissipation tube 2 is cooled and the heat dissipation tube 2 is cooled. The air circulation in the heat tube 2 can cool the casting sand in the heat dissipation tube 2. The stirring rod 5 can be rotated by the output end of the stirring motor 4. The rotation of the stirring rod 5 can mix the casting sand in the heat dissipation tube 2, thereby improving the heat dissipation efficiency of the casting sand in the heat dissipation tube 2. The exhaust fan 11 extracts the air in the heat dissipation tube 2 and discharges the air in the heat dissipation tube 2 into the water in the water tank 10 through the immersion pipe 12.

[0020] In a further preferred embodiment of the present invention, Figure 2 As shown, the lower surface of the heat dissipation tube 2 is connected to a dust exhaust pipe 8.

[0021] In this embodiment, when the foundry sand is stirred, dust will fall to the bottom of the heat dissipation tube 2. By regularly opening the valve on the dust discharge pipe 8, the dust accumulated in the heat dissipation tube 2 can be discharged.

[0022] In a further preferred embodiment of the present invention, Figure 1 As shown, a baffle 6 is hingedly connected to the inner wall of the equipment panel 1 .

[0023] In this embodiment, the baffle 6 shields the feed port of the feed hopper 3 entering the heat dissipation tube 2 , thereby preventing the dust in the heat dissipation tube 2 from being emitted through the feed hopper 3 .

[0024] In a further preferred embodiment of the present invention, Figure 1 As shown, the outer wall of the device board 1 is fixedly connected with heat dissipation fins 14 .

[0025] In this embodiment, the heat dissipation fins 14 increase the surface area of ​​the outer wall of the heat dissipation tube 2 , thereby improving the heat exchange between the heat dissipation tube 2 and the air and improving the heat dissipation efficiency of the heat dissipation tube 2 .

[0026] In a further preferred embodiment of the present invention, Figure 1 As shown, a roller 13 is fixedly connected to the lower surface of the equipment plate 1.
