[0002] A high-level tank is a container installed at a higher position. It is also called a high-level cylinder, high-level storage tank, high-level tank, drip tank, and metering tank due to usage or other reasons. It is suitable for storing liquid foods such as fresh milk, sugar, juice, and condiments. It is an essential equipment for storing liquids in the food, pharmaceutical, and chemical industries. The liquid supply principle of the high-level tank is to use the constant pressure relative to the outlet position of the filling pipe generated by the constant liquid level. When the pressure is constant, the liquid flow rate at the outlet of the filling pipe is constant under ideal conditions. According to the constant cross-sectional area of ​​the outflow pipe, the amount of liquid flowing out of the outlet of the filling pipe per unit time is relatively constant. At present, the preparation of cefuroxime sodium requires the use of a high-level tank to hold dichloromethane or other reaction liquids.
