The invention provides an energy-saving
distillation device of multifunctional lubricating
oil production equipment. The device comprises a
distillation tank, a tank cover, a stirring motor, an
auger,a control panel, a heater, support legs, a fixed base, a lubricating oil guide
pipe, an oil
discharge pipe with a valve, a temperature sensor and an air guide
pipe, and the upper end of the
distillation tank is in threaded connection with the tank cover. A
waste heat heating
water storage tank, a hollow hanging seat, a water injection cover, a drain valve, a
circulating pump and a
waste heat waste-free reutilization heating circulating pipe are arranged, thus facilitating
resource saving, and avoiding waste of
thermal energy resources; when the heater is used for heating the distillation tank, heat is dissipated and the
waste heat waste-free reutilization heating circulating pipe can be heated; at this time, water in the waste heat heating
water storage tank is continuously sucked out through the
circulating pump, circulating heating is continuously conducted through the waste heat waste-free reutilization heating circulating pipe, heat recycling work can be conducted, resource wasteis avoided, energy is saved, environmental friendliness is achieved, and no
pollution is caused.
