Constant-pressure charging hopper for clindamycin propylidene reaction kettle

The invention discloses a constant-pressure feeding hopper for a clindamycin propylidene reaction kettle, and relates to the technical field of feeding devices, the constant-pressure feeding hopper comprises a mounting rack, a storage barrel and a compression barrel are fixed on the mounting rack, the bottom of the compression barrel is communicated with a communicating pipe, and a piston disc in sliding sealing connection with the inner wall of the compression barrel is fixed at the lower end of a lifting rod; a feeding hollow shaft extending into the storage barrel is rotationally installed on the transmission box, and a rotation driving assembly used for driving the rotating frame to rotate is installed in the transmission box. According to the constant-pressure extrusion feeding device disclosed by the invention, the arranged turntable rotates, and the transmission column slides relative to the concentric-square-shaped frame plate, so that the concentric-square-shaped frame plate drives the piston disc to
