Polyester resin polyreactor

The invention discloses a polyester resin polyreactor. The polyester resin polyreactor comprises a reactor body, supporting legs, a feeding pipe, a discharging shell, a sealing plug, a connection rod,a sealing cap, a sealing block, a suction pipe, a vacuum pump, a heating shell, an insulation block, an electrical heating wire, a cooling shell, a condensed water pipe, a condensed water pipe valve,a water outlet pipe, a water outlet valve, a discharging pipe, a discharging valve, a power source wire, a first motor, a first rotary shaft, a first spiral stirring rod, a stirring blade, a second rotary shaft, a second motor, a second spiral stirring rod and a pressure gauge. The polyester resin polyreactor is reasonable in structure and novel in design, through good vacuum environment in the reactor body, polyester resin is prevented from being disturbed by outside gas to affect the quality of a reactant, a worker can operate the polyester resin polyreactor conveniently, even heating in the reactor body is ensured,
