Vacuum distilling apparatus for easy-curing material

The invention provides a vacuum distilling apparatus for easy-curing material, relating to liquid distilling equipment; the distilling apparatus is composed of an evaporator 8, a low boiling point liquid storage pot 9, a discharging pump 7, an easy-curing material liquid storage pot 10, a condenser 11 and a vacuum set 12, and a set of liquid pressurizing device 6 which is composed of a liquid pressure storage tank 4, a mass flowmeter or a weighting module 6, a three-way pressure automatic adjusting control valve 5, a liquid level controller 3, a positive displacement pump 2 and a solvent storage tank 1 is additionally arranged. The liquid isolation technology, metering feedback technology and magnetic transmission technology are adopted, the solvent for charging curing agents is used as spacer fluid of a sliding bearing of the pump, magnetic transmission driven wheel and polymer, thereby achieving the purposes of cleaning structural dead angle of the sliding bearing in an on-line way and not affecting the vac
