[0016] (1) By setting up an anti-overflow box, controller, filling port, first circulation pump, suction pipe, ultrasonic liquid level sensor, return pipe and solenoid valve, when in use, the cooling medium is added into the inner tank. The heat-treated workpiece is slowly lowered into the inner tank for quenching. As the liquid level rises, the ultrasonic liquid level sensor senses that the liquid level exceeds the preset threshold. The first circulation pump draws the cooling medium in the inner tank into the anti-overflow box through the suction pipe. At this time, the solenoid valve is closed to prevent the medium from flowing back into the inner tank through the return pipe. As the workpiece is taken out, the ultrasonic liquid level sensor senses that the liquid level in the inner tank drops. At this time, the solenoid valve is opened and the medium flows back.

The cooled refrigerant flows back into the serpentine copper tube, and works with the graphite heat conduction plate to continuously cool down the inner tank, so that the temperature of the cooling medium in it drops rapidly, thus realizing the function of rapid cooling of the medium.

The controller 5 and the solenoid valve 11 are electrically connected to prevent the medium from overflowing.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, when the ultrasonic level sensor 9 detects that the liquid level exceeds the preset threshold, the first circulation pump 7 draws the cooling medium in the inner tank 2 into the anti-overflow box 4 through the suction pipe 8. At this time, the solenoid valve 11 is closed to prevent the medium from flowing back into the inner tank 2 through the return pipe 10. As the workpiece is removed, the ultrasonic level sensor 9 detects that the liquid level in the inner tank 2 drops. At this time, the solenoid valve 11 opens, and the medium flows back. The filling port 6 is used for ventilation and replenishment of adjustment medium. The controller 5, the first circulation pump 7, the ultrasonic level sensor 9, and the solenoid valve 11 are electrically connected. This technology is existing technology and will not be described in detail.

[0029] A flange 12 is fixedly connected to the bottom right side of the overflow box 4. An electric heating tube 13 is fixedly connected to the right side of the flange 12 through the flange. The electric heating tube 13 passes through the flange 12 and extends into the interior of the overflow box 4. The controller 5 and the electric heating tube 13 are electrically connected to facilitate heating of the medium.

[0030] Specifically, such as Figure 1 and Figure 2As shown, the first circulating pump 7 continuously sends the medium into the overflow box 4 through the suction pipe 8, and then returns it through the return pipe 10 to form a circulation. The electric heating tube 13 at the flange port 12 heats the continuously flowing medium to reach a suitable quenching temperature. The controller 5 and the electric heating tube 13 are electrically connected. This technology is existing technology, so it will not be described in detail.

[0031] A fixed frame 14 is fixedly connected to the left side of the outer tank 1. An inlet chamber 15 is fixedly connected to the front end of the fixed frame 14, and an outlet chamber 16 is fixedly connected to the rear end of the fixed frame 14. Multiple sets of square tubes 17 are welded between the inlet chamber 15 and the outlet chamber 16. Multiple sets of aluminum alloy fins 18 are welded between each pair of square tubes 17. A fan 19 is installed on the left side of the square tubes 17. A second circulation pump 20 is installed at the bottom of the inlet chamber 15. A graphite heat-conducting plate 22 is fixedly connected to the bottom of the inner tank 2. A serpentine copper tube 21 is fixedly connected inside the top of the graphite heat-conducting plate 22. The bottom ends of the outlet chamber 16 and the second circulation pump 20 are respectively connected to the serpentine copper tube 21. The top ends of the serpentine copper tube 21 and the graphite heat-conducting plate 22 are attached to the bottom of the inner tank 2. The controller 5, the fan 19, and the second circulation pump 20 are electrically connected to facilitate the cooling of the medium.

[0032] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, the second circulation pump 20 starts, causing the refrigerant in the serpentine copper tube 21 to flow continuously along the inlet chamber 15, the square tube 17, and the outlet chamber 16. The aluminum alloy fins 18 conduct heat to rapidly cool the refrigerant. The cooled refrigerant flows back into the serpentine copper tube 21, and works with the graphite heat-conducting plate 22 to continuously cool the inner tank 2, causing the temperature of the cooling medium inside to drop rapidly. The controller 5, the fan 19, and the second circulation pump 20 are electrically connected. This technology is existing technology, so it will not be described in detail.

[0033] Working Principle: In use, the cooling medium is first added to the inner tank 2. The heat-treated workpiece is slowly lowered into the inner tank 2 for quenching. As the liquid level rises, the ultrasonic level sensor 9 detects that the liquid level exceeds a preset threshold. The first circulation pump 7 then draws the cooling medium from the inner tank 2 into the overflow tank 4 through the suction pipe 8. At this time, the solenoid valve 11 closes to prevent the medium from flowing back into the inner tank 2 through the return pipe 10. As the workpiece is removed, the ultrasonic level sensor 9 detects that the liquid level in the inner tank 2 drops. At this time, the solenoid valve 11 opens, allowing the medium to flow back. The filling port 6 is used for ventilation and replenishing / adjusting the medium. In low-temperature weather such as winter, the medium needs to be heated. The first circulation pump 7 continuously sends the medium into the overflow tank 4 through the suction pipe 8, and then it flows back through the return pipe 10 to form a circulation. The heating element 13 at the flange 12 heats the continuously flowing medium to reach a suitable quenching temperature. After the medium undergoes multiple quenching processes, its temperature will rise significantly. When it is necessary to cool the medium, the second circulation pump 20 is started, causing the refrigerant in the serpentine copper tube 21 to flow continuously along the inlet chamber 15, the square tube 17, and the outlet chamber 16. The aluminum alloy fins 18 conduct heat to rapidly cool the refrigerant. The cooled refrigerant then flows back into the serpentine copper tube 21, working in conjunction with the graphite heat-conducting plate 22 to continuously cool the inner tank 2, causing the temperature of the cooling medium inside to drop rapidly.
