The lower side of the hopper 24 is adjusted to push the rotating plate 25 to rotate and then adjust the size of the material discharge opening between the rotating plates 25, so as to achieve the effect of adjusting the feeding amount of the hopper 24.

[0044] The implementation principle of a sealed feeding device for a reactor in an embodiment of the present application is as follows: the sealing plate 22 is closed, the cover plate 23 is opened, and material is fed into the hopper 24. After the feeding is completed, the motor 11 drives the sealing plate 22 to rotate and open, and the cover plate 23 is closed. At this time, the push rod 32 is pushed to drive the push plate 31 to slide, and the push plate 31 pushes the hopper 24 to slide, and the hopper 24 pushes the rotating plate 25 to rotate and open for feeding. After the feeding is completed, the spring 29 pushes the hopper 24 to return, and the torsion spring 251 drives the rotating plate 25 to return, which is convenient for the next feeding.

[0045] When the feed amount of the hopper 24 needs to be adjusted, the screw 236 is rotated to drive the limit ring 235 to move, and the blocking ring 321 at one end of the push rod 32 is blocked on one side of the limit ring 235, so as to adjust the displacement of the hopper 24 and then adjust the size of the feed opening between the rotating plates 25, thereby achieving the effect of adjusting the feed amount.
