The pushing rods 305 on both sides of the T-shaped plug 306 can push the No. 1 connecting rod 303 and the No. 2 connecting rod 304 to rotate with the limiting sheet metal 307 as the center, and then push the sealing bottom plate 302 to rotate with the mounting bracket 301 as the center, so that the sediment below the sedimentation box 217 is exposed and the sediment is discharged from the sedimentation box 217.

[0038] The working principle of the present invention is as follows: amino acid solvent is added to the protective box 101 for solvent precipitation reaction.
