The bottom inlet of the coil 18 is connected to the liquid inlet tank 5 via a liquid delivery pipe 9, and the top outlet is connected to the liquid supply device 4 via a liquid outlet pipe 7. The heating device 2 is connected via a heating pipe 6. By connecting the liquid supply device 4 and the heating device 2 to the quenching device 1, the device recovers and reuses the residual heat generated by the quenching device 1. In conjunction with the heating device 2, it facilitates reheating of the quenching device 1. The device is easy to operate, use, and maintain, making it suitable for widespread application. A control valve is installed between the top outlet of the coil 18 and the liquid outlet pipe 7 and heating pipe 6. The control valve controls the flow direction within the coil 18 and the liquid outlet pipe 7 and heating pipe 6, thereby recovering residual heat and heating the quenching device.

[0032] A filter box 11 is provided between the heating device 2 and the liquid supply device 4.

[0033] The heating device 2 includes a heating tube 16 and a filter plate 14 disposed within the housing. The heating tube 16 is located at the bottom of the heating device 2, and the filter plate 14 is located above the heating tube 16, below the outlet of the heating pipe 6. Multiple steam holes 15 are evenly distributed on the filter plate 14. A pressure monitor 17 is installed on the exterior of the heating device 2, below the filter plate 14.

The discharged liquid is introduced into the liquid supply device 4 through the liquid outlet pipe 7. When the temperature inside the quenching device 1 is too low and needs to be heated, the liquid in the liquid supply device 4 is discharged into the heating device 2 and heated by the heating pipe 16. The heated steam is filtered through the liquid filter plate 14 and then flows into the quenching device 1 through the heating pipe 6 to heat the quenching device 1.
