[0023] The working principle of the utility model is as follows: the first liquid level sensor is provided with a first threshold value and a second threshold value, and the value of the first threshold value is greater than the value of the second threshold value.

[0024] The first step is to connect the external pipeline to the feed pipe, press the first button to control the first electric valve to open the feed pipe channel, and then extract oleic acid through the external extractor, so that the oleic acid enters the distillation kettle through the external pipeline and the feed pipe. When the oleic acid level inside the distillation kettle reaches the first threshold preset by the first liquid level sensor, the buzzer is controlled to sound for a certain period of time to remind the staff to close the external extractor.

The temperature sensor detects the temperature of the oleic acid, thereby controlling the temperature generated by the heating rod and the heater to achieve a constant temperature heating effect. The hot air in the heating shell will be discharged through the exhaust pipe. The vacuum pump starts to extract the water vapor generated in the distillation kettle, so that the water vapor enters the cooling box through the second delivery pipe and the first delivery pipe. The refrigerator cools the water vapor and converts it into distilled cold water. After the oleic acid is distilled, press the second button again to control the drive motor, heater, heating rod, vacuum pump and refrigerator. Stop working, then control the second electric valve to open the discharge pipe channel, and the oleic acid after distillation is discharged through the discharge pipe. When the oleic acid level inside the distillation kettle is lower than the second threshold value preset by the first liquid level sensor, the second electric valve is controlled to close the discharge pipe channel, and the water pump is controlled to work at the same time. The water pump extracts cold water in the cooling box, and the cold water flows into the cleaning device through the first water pipe and the second water pipe, and then is sprayed on the inner wall of the distillation kettle through the cleaning device, so as to clean the inside of the distillation kettle, thereby completing the cleaning work inside the distillation kettle. When the cold water level in the cooling box is lower than the threshold value preset by the second liquid level sensor, the water pump is controlled to stop working, and the second electric valve is controlled to open the discharge pipe channel, and the waste water is discharged through the discharge pipe. When all the waste water is discharged, press the third button to control the second electric valve to close the discharge pipe channel.
