When it is necessary to add perfluoromethyl vinyl ether raw material to the reactor, the sealing cover 263 is rotated off the top of the funnel 260 by holding the handle 264. Then, the raw material for preparing perfluoromethyl vinyl ether is added into the feeding cylinder 200. Subsequently, under the action of gravity, the raw material for preparing perfluoromethyl vinyl ether flows into the feeding cylinder 200 through the feed pipe 261. Then, the handwheel 241 is rotated, causing the rotating shaft 240 to drive the auger 250 to rotate. The screw conveyor 250 transports the raw material for perfluoromethyl vinyl ether preparation to the discharge pipe 270. By opening the first valve 271, the raw material for perfluoromethyl vinyl ether preparation enters the cavity between the first valve 271 and the second valve 272. Then, the first valve 271 is closed and the second valve 272 is opened, allowing the raw material for perfluoromethyl vinyl ether to be transported to the reactor for perfluoromethyl vinyl ether preparation under gravity. This facilitates the control of the feeding of the perfluoromethyl vinyl ether raw material and maintains the pressure in the reactor during the reaction process, thus improving the practicality and stability of the equipment.
