The first temperature sensor 20 with the reflux valve 16 opened, this design allows the silicone oil inside the stirring kettle body 1 to be discharged from the inside into the serpentine heat dissipation pipe 13, and the silicone oil is cooled under the action of the coolant inside the heat dissipation box 9, which facilitates the heat dissipation, cooling and cooling of the silicone oil. At the same time, the conveying speed of the silicone oil is slowed down under the action of the serpentine heat dissipation pipe 13, so that the silicone oil can be fully cooled and dissipated. When the first temperature sensor 20 detects that the temperature of the silicone oil flowing out of the guide pipe 21 exceeds the set value, the discharge valve 18 is closed and the reflux valve 16 is opened. Under the action of the pump body 7, the silicone oil that has not been completely cooled and dissipated will flow back to the inside of the stirring kettle body 1, avoiding the phenomenon that the silicone oil is discharged without timely heat dissipation, thereby enhancing the heat dissipation effect and improving the cooling quality of the silicone oil.

[0027] Reference Figure 2 , Figure 3 and Figure 4The side wall of the heat dissipation box 9 is provided with a second temperature sensor 22 for detecting the temperature of the coolant, the side wall of the heat dissipation box 9 is provided with a buzzer 23, the top of the heat dissipation box 9 is provided with a PLC controller 6, the input end of the PLC controller 6 is provided with an A / D converter, the output end of the PLC controller 6 is provided with a D / A converter, the first temperature sensor 20 and the second temperature sensor 22 are electrically connected to the A / D converter respectively, the buzzer 23, the reflux valve 16, and the discharge valve 18 are electrically connected to the D / A converter respectively. By using the PLC controller 6, when the first temperature sensor 20 detects that the temperature of the silicone oil flowing out of the guide pipe 21 exceeds the set value, the signal The heat is then transmitted to the PLC controller 6, which closes the discharge valve 18 and opens the reflux valve 16. Otherwise, the discharge valve 18 is opened and the reflux valve 16 is closed to ensure that the silicone oil with qualified cooling flows out. Under the action of the pump body 7, the silicone oil that has not been completely cooled down will flow back to the inside of the stirring kettle body 1 to avoid the phenomenon that the silicone oil is not discharged in time due to untimely heat dissipation, thereby enhancing the heat dissipation effect and improving the cooling quality of the silicone oil. When the second temperature sensor 22 detects that the temperature of the coolant in the heat dissipation box 9 exceeds the set value, the signal is transmitted to the PLC controller 6, and the PLC controller 6 activates the buzzer 23 to issue a warning that the coolant needs to be replaced. Otherwise, the buzzer 23 does not work.

[0028] Reference Figure 1 and Figure 3 A support leg 10 is provided at the bottom corner of the heat dissipation box body 9, and a support plate 8 for supporting the pump body 7 is provided on the side wall between adjacent support legs 10. This design improves the stability of the connection of the pump body 7. A one-way valve 31 is provided on the side wall of the return pipe 3. This design avoids fluid reflux by using the one-way valve 31.

[0029] Reference Figure 1-Figure 4As an embodiment of the utility model: when the silicone oil needs to be cooled and cooled, the staff opens the discharge valve 15 and makes the pump body 7 work at the same time, and the silicone oil flows out from the discharge pipe 14 into the serpentine heat dissipation pipe 13, and the silicone oil is cooled and cooled under the action of the coolant inside the heat dissipation box 9, which facilitates the heat dissipation and cooling of the silicone oil.

When the first temperature sensor 20 detects that the temperature of the silicone oil flowing out of the guide pipe 21 exceeds the set value, the signal is sent to the PLC control Device 6, PLC controller 6 closes the discharge valve 18 and opens the reflux valve 16, and under the action of the pump body 7, the silicone oil that is not completely cooled down by heat is refluxed into the inside of the stirring kettle body 1, so as to avoid the phenomenon that the silicone oil is not discharged in time due to untimely heat dissipation, thereby enhancing the heat dissipation effect and improving the cooling quality of the silicone oil. When the first temperature sensor 20 detects that the temperature of the silicone oil flowing out of the guide pipe 21 does not exceed the set value, the signal is transmitted to the PLC controller 6, and the PLC controller 6 opens the discharge valve 18 and closes the reflux valve 16, so as to ensure that the silicone oil that is qualified for cooling is discharged, improve the cooling quality, and improve the practicality of the utility model.
