[0028] The embodiment of the present application discloses a cooling device for a crucible.

[0029] Reference Figure 1-3 A crucible cooling device includes a placement box 1, a placement slot 11 for placing the crucible is provided on the placement box 1, the placement box 1 is hollow, a cooling mechanism 214 is connected to the placement box 2, a plurality of temperature sensors 3 and a discharge port 12, the cooling mechanism 214 is provided on the placement box 1, a plurality of temperature sensors 3 are arranged in an equidistant array on the side wall of the placement box 1, and the discharge port 12 is provided at the bottom of the placement box 1 and the bottom of the cooling mechanism 214;

[0030] The cooling mechanism 214 includes a cooling component 21 and a spray component 22. One end of the spray component 22 is connected to the placement box 1, and the other end of the spray component 22 is connected to the cooling component 21. The liquid inlet end of the cooling component 21 is connected to the placement box 1.

[0031] During use, the crucible is placed on the placement slot 11 of the placement box 1, and multiple temperature sensors 3 monitor the temperature of the crucible. After the temperature sensor 3 feeds back the detected temperature, the control end calculates the detected temperature. If the overall temperature of the crucible is high, the spray assembly 22 is controlled to cool the entire crucible. When it is necessary to cool a part of the crucible, the spray assembly 22 is regulated to cool the part of the crucible, so as to adjust the temperature fluctuation of the crucible, thereby controlling the temperature stability during the arc starting process of the crucible R angle.

[0032] Reference Figure 1-3 The cooling assembly 21 includes a cooling box 211, a connecting pipe 212, a cooling pipe 213 and a cooling machine 214. One end of the connecting pipe 212 is connected to the placement box 1, and the other end of the connecting pipe 212 is connected to the cooling box 211. The cooling pipe 213 is located in the cooling box 211. The cooling machine 214 is fixedly arranged on the outer wall of the cooling box 211. The cooling pipe 213 is connected to the cooling box 211, and the liquid inlet end and the liquid outlet end of the connecting pipe 212 are respectively at a certain height distance from the bottom of the cooling box 211 and the bottom of the placement box 1, so that the cooling liquid after heat exchange can be settled in the placement box 1 for a period of time, and then the cooling liquid above is discharged into the cooling box 211 through the connecting pipe 212.

[0033] During use, the cooling water is stored in the cooling box 211, and the cooling pipe 213 is driven by the cooling machine 214 to cool the cooling water in the cooling box 211. At the same time, the cooling power of the refrigerator is adjusted to adjust the cooling temperature of the cooling pipe 213, which can control the cooling problem of the cooling water and improve the cooling efficiency of the crucible. The connecting pipe 212 can recover the coolant after heat conversion and return it to the cooling box 211 for re-cooling.

[0034] Reference Figure 2-3 A filter screen 215 is provided in the middle of the cooling box 211. The filter screen 215 can further filter the cooling water after heat exchange to prevent impurities in the cooling water from entering the variable frequency water pump 224 and causing damage to the variable frequency water pump 224.

[0035] Reference Figure 1-3 The spray assembly 22 includes a plurality of spray pipes 221, a plurality of nozzles 222, a branch main pipe 223 and a variable frequency water pump 224. The plurality of spray pipes 221 are respectively connected to the branch main pipe 223. The plurality of nozzles 222 are circumferentially arranged on the spray pipes 221. The branch main pipe 223 is connected to the variable frequency water pump 224.

[0036] When in use, after receiving instructions from the control end, the variable frequency water pump 224 pumps the cooling water in the cooling water tank to the branch main pipe 223, and evenly distributes the cooling water to each spray pipe 221 through the branch main pipe 223. The cooling water is sprayed through the nozzle 222 to evenly cool the entire crucible. The variable frequency water pump 224 regulates the spraying pressure of the cooling water, which can effectively control the cooling efficiency.

[0037] Reference Figure 1-3 An electronic valve 225 is provided at the connection between the spray pipe 221 and the branch main pipe 223. The setting of the electronic valve 225 can effectively control the spraying state of each spray pipe 221, so that the spray pipe 221 can accurately and quickly cool down a certain part of the crucible to ensure the use of the crucible.

[0038] Reference Figure 2-3 The cooling box 211 is also provided with a liquid adding pipe 216 for adding coolant to prevent the cooling effect of the crucible from being lost after the coolant evaporates.

[0039] Reference Figure 1 A transparent observation strip 4 is provided at the bottom of the placement box 1 and the cooling box 211. Through the setting of the observation strip 4, the impurity sedimentation in the placement box 1 and the cooling box 211 can be effectively observed, and the settled impurities can be cleaned in time and new cooling water can be replaced.

[0040] Reference Figure 1-2The discharge port 12 is connected to the bottom of the placement box 1 and the bottom of the cooling box 211 respectively, and a sealing valve 13 is provided on the discharge port 12. By switching the sealing valve 13, the impurities in the placement box 1 and the cooling box 211 can be effectively discharged synchronously.

[0041] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
