Detailed Description

The technical solution of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example one

As shown in fig. 2, a valveless solid closed charging cover plate device comprises: a sealing box 1 and a feeding pipe 4. Wherein, the feed pipe 4 has a first port 41 and a second port 42 which are opposite, the first port 41 is communicated with the seal box 1, and the second port 42 is communicated with the reaction kettle 5. This filling tube 4 is the cavity pipeline, and intraductal not setting up the valve. The first port 41 is fitted with a flange 8 and a movable cover plate 2. The cover plate 2 is provided with a buckle structure 7, and the cover plate 2 and the flange 8 are locked by the buckle structure 7 and are in a tight closing state.
