Automatic negative pressure liquid medicine feeding device

Abstract

The utility model belongs to the field of liquid medicine processing technology, concretely relates to a kind of automatic feeding device of negative pressure type liquid medicament, including bottom plate, bottom plate top surface installs control panel, control panel surface electric connection vacuum pump, vacuum pump suction port surface connects first connecting pipe, first connecting pipe other side surface screw thread connection first ball valve, first ball valve other side surface screw thread connection second connecting pipe, second connecting pipe surface is connected in buffer tank top, buffer tank top surface connects third connecting pipe, third connecting pipe surface screw thread connection second ball valve.The utility model, by the cooperation of vacuum pump, buffer tank, liquid medicine tank and four ball valves, the liquid medicine needing feeding is carried out full-closed negative pressure conveying, and different viscosity and characteristics of liquid medicine can be adapted, and the maintenance requirement of vulnerable parts can also be reduced;And the operating parameters of vacuum pump and each ball valve can be set and controlled by control panel, so as to ensure that liquid medicine is stably and uniformly fed.
