[0028] Specifically: the check valve 205 is used to prevent the heat transfer oil from flowing back when the oil pump 207 stops.

[0029] In one embodiment, the control component 3 includes a control terminal 301 , a temperature sensor 302 , and a pressure sensor 303 .

[0030] Specifically: the pressure sensor 303 can transmit the real-time pressure in the heating tube 209 to the large screen in the control room through the control terminal for display, so as to prevent the pressure in the heating tube 209 from being too high, which may cause certain dangers.

[0031] In one embodiment, the surface of the oil inlet pipe 202 is fixedly embedded in the oil inlet pipe groove 104, the bottom of the oil pump 207 is fixedly connected to the bottom of the inner cavity of the thermal oil furnace body 1, the surface of the oil pump oil outlet pipe 208 is fixedly embedded in the oil pump oil outlet pipe groove 106 and the oil outlet pipe groove 101, and the surfaces of the two ends of the U-shaped tube 203 are fixedly embedded in the two pipe grooves 107.

[0032] Specifically, the U-shaped tube 203 can increase the heat exchange time between the heat transfer oil inside the U-shaped tube 203 and the higher temperature of the upper inner cavity of the heat transfer oil furnace body 1, and can fully utilize the heat emitted by the heating tube 209 for preheating, thereby achieving the purpose of energy saving.

[0033] In one embodiment, one side of the control terminal 301 is fixedly connected to the side of the thermal oil furnace body 1, and the surfaces of one end of the temperature sensor 302 and the pressure sensor 303 are fixedly embedded in the interior of the heating tube 209, the surface of the temperature sensor 302 is fixedly embedded in the interior of the temperature sensor groove 102, and the surface of the pressure sensor 303 is fixedly embedded in the interior of the pressure sensor groove 103.

Under the action of the oil pump 207, the heat transfer oil is pumped into the oil pump outlet pipe 208, and the heat transfer oil flows through the heating cylinder 209. The oil pump outlet pipe 208 inside the heating cylinder 209 is U-shaped. When the heat transfer oil flows through the heating cylinder 209, the heating time of the heat transfer oil by the heating resistor 210 inside the heating cylinder 209 is increased. After the heating is completed, it goes out through the oil outlet 211. After a cycle, the heat transfer oil with a relatively low temperature is discharged from the oil inlet again. When 201 enters the U-tube 203, the surrounding temperature of the heating tube 209 is high due to the continuous heating. When the heat transfer oil passes through the U-tube 203, it can preheat the heat transfer oil in the U-tube 203. This design can make full use of the heat emitted by the heating tube 209 to preheat the heat transfer oil. When the heat transfer oil enters again, the required heating time will be shortened, thereby achieving the purpose of energy saving. The temperature sensor 302 will send the real-time temperature in the heating tube 209 to the control terminal 301. The control terminal 301 can adjust the output power of the oil pump 207 and the heating resistor 210 according to the temperature sent by the temperature sensor 302. This design can adjust the output power of the heating resistor 210 and the oil pump 207 according to the real-time temperature of the heat transfer oil. There is no need to blindly heat the heat transfer oil and cause energy waste, thereby improving the energy saving effect of the device.
