[0023] When in use, the pressure relief box 4 and the straight pipe 10, air inlet, sealing ring block 12 and compression spring 15 inside it effectively solve the problem that the existing device does not have a pressure relief mechanism. When the heating device is running, once the internal pressure exceeds the safe range, the high-pressure gas enters the pressure relief box 4 and pushes the sealing ring block 12 upward. It can flow into the straight pipe 10 through the air inlets on both sides of the straight pipe 10, and then the high-pressure gas is safely released through the pressure relief pipe 9, thereby effectively avoiding the safety hazard of overpressure, greatly improving the safety of equipment and personnel, and enhancing the practicality and reliability of the device.

[0024] Furthermore, an adjusting disk 16 is provided on the outer side of the straight tube 10 above the compression spring 15. The adjusting disk 16 is fixedly connected to the compression spring 15. A threaded rod 17 is rotatably installed on one side above the adjusting disk 16. The threaded rod 17 is threadedly connected to the pressure relief box 4, and the upper end of the threaded rod 17 extends to the top of the pressure relief box 4. A handwheel is fixedly installed above the threaded rod 17. By rotating the handwheel to drive the threaded rod 17 up and down, the preload force of the compression spring 15 can be easily adjusted, thereby realizing the control of the pressure relief pressure, which not only improves the safety performance of the device, but also enables the device to adapt to the pressure requirements under different working conditions, thereby enhancing its practicality.

[0025] Furthermore, a guide column 18 is fixedly installed on the other side above the adjusting disk 16, and the upper end of the guide column 18 slides and extends above the pressure relief box 4. Scale lines are provided on the outer surface of the guide column 18. The guide column 18 not only provides a stable support for the adjusting disk 16, but also intuitively displays the position of the adjusting disk 16 through the scale lines, which is convenient for the operator to quickly and accurately adjust the pressure relief pressure. This intuitiveness improves operating efficiency and reduces the risk of misoperation.

[0026] Furthermore, an inner sealing ring 13 is fixedly installed on the inner side of the sealing ring block 12, and the inner sealing ring 13 fits with the straight pipe 10. An outer sealing ring 14 is fixedly installed on the outer side of the sealing ring block 12, and the outer sealing ring 14 fits with the inner wall of the pressure relief box 4. The setting of the inner and outer sealing rings ensures the sealing inside the pressure relief box 4, prevents leakage of high-pressure gas, and improves the safety and reliability of the device.

[0027] Furthermore, an inner tube 5 is fixedly installed inside the heating tube 1, a circulation cavity is provided inside the heating tube 1 along the inner tube 5, a heating cavity is provided inside the heating tube 1 along the outer side of the inner tube 5, an electric heating tube 6 is provided inside the heating cavity of the heating tube 1, and the electric heating tube 6 is spirally arranged. The spirally arranged electric heating tube 6 can heat the medium in the circulation cavity more evenly, thereby improving the heating efficiency and temperature uniformity.

[0028] Furthermore, a thermal conductive plate 7 is provided inside the flow cavity of the heating tube 1, and there are multiple thermal conductive plates 7.

The thermal conductive plate 7 can accelerate the transfer of heat and improve the heating efficiency. At the same time, the setting of the through hole helps to increase the fluidity and mixing effect of the medium, further improving the uniformity of heating.

[0029] Furthermore, a temperature sensor 8 is provided inside the flow cavity of the heating tube 1. The temperature sensor 8 adopts a pt100 temperature sensor, and there are multiple temperature sensors 8. The setting of multiple temperature sensors can conveniently monitor the temperature distribution inside the heating device, provide accurate temperature information for the operator, help to adjust the heating parameters in time, and ensure the stability and controllability of the heating process.

[0030] Working principle: When in use, the device heats the water input into the circulation cavity through the electric heating tube 6 inside the heating tube 1. The spiral setting of the electric heating tube 6 ensures the uniformity and efficiency of heating. During the heating process, the water flows in the circulation cavity and evaporates due to heat and gathers to form high-pressure steam output. The set temperature sensor 8 is convenient for real-time monitoring of the temperature distribution inside the heating device, providing accurate temperature information for the operator to adjust the heating parameters in time. When the internal pressure of the heating device exceeds the safe range, the high-pressure gas enters the pressure relief box 4, pushing the sealing ring block 12 to move upward, and can flow into the straight pipe 10 through the air inlets on both sides of the straight pipe 10. Then the high-pressure gas is safely released through the pressure relief pipe 9, effectively avoiding the safety hazard of overpressure. In addition, the threaded rod 17 can be driven up and down by rotating the handwheel, and the preload force of the compression spring 15 can be conveniently adjusted to adjust the pressure relief pressure, thereby enhancing the practicality and safety of the device.
