Description

Liquid medicine buffer tank with pressure balancing function Technical Field The utility model relates to the technical field of liquid medicine buffer tanks, in particular to a liquid medicine buffer tank with a pressure balancing function. Background The liquid medicine buffer tank is a key device for storing, mixing and stabilizing liquid medicine in the fields of pharmacy, chemical engineering, biological engineering and the like, and has the core functions of balancing system pressure fluctuation, maintaining stable physical and chemical properties of the liquid medicine and ensuring continuity and safety of a process flow. However, the existing liquid medicine buffer tank has the following problems that the buffer device of liquid medicine is not arranged in the buffer tank, so that after the liquid medicine is injected into the buffer tank for a long time, the anti-corrosion layer on the inner wall of the buffer tank is easily damaged, the corrosion of the wall of the buffer tank is further caused, the service life of the buffer tank is influenced, meanwhile, sediment is easily generated when the liquid medicine in the buffer tank is kept for a long time, and the product quality is reduced.
