The preheating chamber 1-1 and the water storage chamber 1-2 are connected through a connecting pipe 2. The two ends of the connecting pipe 2 are respectively located at the top of the preheating chamber 1-1 and the top of the water storage chamber 1-2. When the water in the preheating chamber 1-1 is full, the overflowing water will return to the water storage chamber 1-2 from the connecting pipe 2. A water pump 3 is installed on the side of the barrel body 1. The input end of the water pump 3 is connected to the bottom of the water storage chamber 1-2 through a water pipe, and the output end of the water pump 3 is connected to the bottom of the preheating chamber 1-1 through a water pipe. A one-way valve is installed at the output end of the water pump 3, and the water pump 3 can The water in the water storage chamber 1-2 is pumped into the preheating chamber 1-1. A column 4 is installed at the bottom of the preheating chamber 1-1. A preheating oil barrel 5 is installed on the column 4. The function of the column 4 is to lift the preheating oil barrel 5 so that the bottom of the preheating oil barrel 5 does not contact the bottom of the preheating chamber 1-1. An electric heating tube 6 and a liquid temperature sensor 7 are installed in the water storage chamber 1-2. The electric heating tube 6 can heat the water in the water storage chamber 1-2. The liquid temperature sensor 7 can monitor the water temperature in the water storage chamber 1-2 in real time. The water temperature in the water storage chamber 1-2 can be monitored and controlled in real time through the cooperation of the electric heating tube 6 and the liquid temperature sensor 7. Please refer to Figure 2 The height of the preheating chamber 1-1 is greater than the overall height of the column 4 and the preheating oil barrel 5, so the top of the preheating oil barrel 5 does not contact the top of the preheating chamber 1-1. The bottom of the preheating chamber 1-1 is provided with a first drain port 1-3, and a valve is installed on the first drain port 1-3. By opening the valve on the first drain port 1-3, the water in the preheating chamber 1-1 can be discharged. Please refer to Figure 2 A water inlet 1-4 is provided at the top of the water storage chamber 1-2, and a second water outlet 1-5 is provided at the bottom of the water storage chamber 1-2. Valves are installed on the water inlet 1-4 and the second water outlet 1-5. By opening the valve of the water inlet 1-4, water can be added to the water storage chamber 1-2. Salt water can be used as the water added to the water storage chamber 1-2. The heating rate of salt water is faster than that of ordinary pure water. The electric heating tube 6 can heat the salt water to the required temperature faster. By opening the valve of the second drain outlet 1-5, the water in the water storage chamber 1-2 can be discharged.

The controller 8 can control the opening and closing of the water pump 3 and the electric heating pipe 6. The temperature range of the water in the water storage chamber 1-2 can be set on the controller 8. When the electric heating pipe 6 heats the water to the set maximum temperature, the controller 8 controls the electric heating pipe 6 to close. When the water temperature drops to the set minimum temperature, the electric heating pipe 6 is turned on again. A screen is arranged on the controller 8 to display the working status of the device and the water temperature in the water storage chamber 1-2.
[0025] See also Figure 2 and Figure 3 The shape of the preheating oil barrel 5 is cylindrical, so as to increase the contact area between the hot water in the preheating chamber 1-1 and the preheating oil barrel 5, so that the rolling oil in the preheating oil barrel 5 can be preheated faster and more evenly.

An oil inlet 5-1 is arranged on the top of the preheating oil barrel 5, and the inlet end of the oil inlet 5-1 passes through the top of the barrel body 1. The rolling oil to be heated can be added to the preheating oil barrel 5 through the oil inlet 5-1. An oil outlet 5-2 is arranged on the bottom of the preheating oil barrel 5, and the outlet end of the oil outlet 5-2 passes through the side wall of the barrel body 1. A valve is installed on the oil outlet 5-2. The rolling oil in the preheating oil barrel 5 can be discharged by opening the valve of the oil outlet 5-2.
[0026] The working principle and use process of this utility model:
[0027] When using the rolling oil preheating device, first fill the water storage chamber 1-2 with salt water, set the water temperature range, turn on the electric heating tube 6, and when the water temperature in the water storage chamber 1-2 reaches the preset temperature, the electric heating tube 6 is closed, and the rolling oil is poured into the preheating oil barrel 5 from the oil inlet 5-1, and the water pump 3 is started. The water pump 3 pumps the hot water in the water storage chamber 1-2 into the preheating chamber 1-1. After the preheating chamber 1-1 is full of water, the preheating oil barrel 5 is completely immersed in the hot water, and the water in the preheating oil barrel 5 is heated by a water bath. Rolling oil, overflowing water will return to the water storage chamber 1-2 through the connecting pipe 2. When the water temperature in the water storage chamber 1-2 is lower than the preset temperature, the electric heating pipe 6 is turned on again. After the rolling oil in the preheating oil barrel 5 is preheated, the valve of the oil outlet 5-2 is opened to discharge the rolling oil out of the preheating oil barrel 5. When the rolling oil preheating device is not in use, the valve of the first drain port 1-3 and the valve of the second drain port 1-5 are opened to discharge the brine in the preheating chamber 1-1 and the water storage chamber 1-2.
