Problems solved by technology

[0003] Whether the commonly used discharge pumps are gear pumps or screw discharge pumps, whether they use mechanical seals, packing seals or magnetic drives, there are material "dead angles" in the sealing parts and bearing parts, and the materials cannot be renewed in time in these parts. As time goes by, the curing agent quickly polymerizes and thickens, and finally solidifies the drive shaft and burns the motor, which affects the distillation process

Abstract

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 vacuum of the vacuum system, ensuring vacuum distilling separation of high boiling point and thermosensitive substances.

Description

technical field [0001] The invention relates to equipment for liquid distillation, in particular to a vacuum distillation device for liquids containing easily solidified materials. Background technique [0002] For liquid distillation, a common vacuum distillation device is composed of an evaporator 8, a low boiling point liquid storage tank 9, a discharge pump 7, a liquid storage tank 10 for easily solidified materials, a condenser 11 and a vacuum unit 12. After the liquid with low boiling point wherein is separated and removed, because its high boiling point liquid is a kind of easily solidified material, if this material can not be transported to high boiling point liquid storage tank 10 rapidly and completely, the easily solidified material with high boiling point is in pipeline or A slight accumulation in the pump cavity of the discharge pump 7 will stop the production and even cause the discharge pump to be destroyed. For example, the polyurethane curing agent used to...
