This invention provides a multi-site mutant of cocaine esterase, its protein dimer, and its applications. By mutating cysteine ​​(C) at position 107 to serine (S), and cysteine ​​(C) at position 551 to serine (S), arginine (R), or alanine (A), it achieves efficient and uniform cross-linking with BMOE while maintaining cocaine catalytic activity, forming a structurally stable dimer. This modification significantly improves the enzyme's thermostability and prolongs its half-life in vivo. The protein dimer is suitable for the treatment and prevention of acute cocaine poisoning.

The utility model discloses a kind of rheological die-casting aluminum alloy liquid refining devices, solve the low stirring degassing efficiency of aluminum alloy liquid degassing equipment in prior art, and the problem of poor refining effect.The utility model includes vertical column and cantilever beam, the height on vertical column is adjusted by lifting mechanism, and the cantilever beam is slidably arranged on vertical column;Cantilever beam is equipped with stirring mechanism and dross mechanism;Stirring mechanism includes stirring drive and stirrer, and stirring drive drives stirrer to rotate by first transmission mechanism;Dross mechanism includes dross drive and dross baffle, and dross drive drives dross baffle to move up and down by second transmission mechanism.The utility model uses cantilever beam to simultaneously integrate the composite design of stirring mechanism and dross mechanism, realizes stirring and slag removal in parallel, and continuously removes dross;Improve stirring degassing efficiency;Moreover, stirring promotes inclusion to float, and dross mechanism is cleaned instantly, avoid dross secondary involvement melt, and improve refining continuity.
