Micro-computer numerical control medicine feeding device

The utility model provides a micro-computer numerical control medicine feeding device, which mainly solves the problems that the existing liquid chemical agent feeding device of an oil well has inaccurate measurement, the pipeline is frozen in the winter and a check valve is easy to block. The micro-computer numerical control medicine feeding device is characterized in that the bottom of a medicine storage barrel 1 is connected with a filter 6 by a pipeline and a ball valve 13; the filter 6 is connected with a medicine feeding pump by a ball valve 14; the lower part of the medicine feeding pump 7 is connected with an electrode point pressure meter 8, a safety valve 9 and a ball valve 17 and is finally connected with one side of a heating and temperature-preserving pipeline 11 by a quick joint 10; a micro-computer time controller 4 is connected with a temperature control heater 12 and the upper part of the medicine feeding pump 7 respectively by cables; the temperature control heater 12 is arranged below the m
