The invention relates to the technical field of distribution boxes, and provides a distribution box with a dust isolation function, which comprises an outer box, an inner box is mounted on the front side of an inner cavity of the outer box, an air return pipe and an air outlet pipe are sequentially mounted on the left side and the right side of the inner box in a communicating manner, and a refrigeration pipe is mounted at the rear ends of the air return pipe and the air outlet pipe in a communicating manner; a rotating shaft is rotationally installed in the middle of the refrigerating pipe, a first fan blade is fixedly connected to the outer surface of the rotating shaft, and a second fan blade and a third fan blade are fixedly connected to the left end and the right end of the rotating shaft correspondingly; the middle of the outer surface of the refrigeration pipe is fixedly sleeved with a heat preservation sleeve, an inner cavity of the heat preservation sleeve is filled with heat conduction liquid, and a semiconductor refrigerator is fixedly installed on the back face of the heat preservation sleeve. The device is redesigned, the heat dissipation performance is remarkably improved, the heat dissipation efficiency of the inner box is closer to that of direct air cooling convection, and meanwhile the device achieves the efficient heat exchange function through semiconductor refrigeration on the premise that leakage of positive pressure protection gas in an inner cavity of the inner box is not damaged.

The invention relates to the technical field of sapphire processing, and particularly discloses a high-precision sapphire optical wafer intelligent cutting device which comprises a processing platform, a cutting assembly is fixed to the processing platform and comprises a processing seat, and a transverse arc-shaped processing opening is formed in the middle of the side wall of the processing seat; the machining base is further provided with two first mounting grooves symmetrically formed based on the upper end and the lower end of the machining opening, first air cylinders are fixed to the bottoms of the first mounting grooves, a supporting frame is fixed to the output ends of the first air cylinders, a hollow supporting shaft is fixed to the side wall of the supporting frame, and a guide wheel is rotationally connected to the outer wall of the supporting shaft. A plurality of first through holes communicating with the interior of the guide wheel are formed in the outer wall of the supporting shaft, and a plurality of second liquid passing channels correspondingly communicating with the first through holes are formed in the inner wall of the guide wheel in a penetrating mode to the outer wall of the guide wheel along a center array. The problem that an existing sapphire optical wafer cutting device is low in cutting efficiency is solved.

The application discloses a kind of biological medicine efficient polypeptide flushing gel and preparation process, it is related to polypeptide flushing gel preparation technical field, first, at 20 ℃ with 550rpm stirring speed injection water is stirred, and slowly adding sodium carboxymethyl cellulose, after all is added, put into kudzu root polysaccharide, the stirring speed is promoted to 1200rpm and continues to mix 45 minutes, then reduce the speed to 300rpm, add sodium chloride and stir until dissolved, make up injection water, and adjust pH to 7.0-7.5, prepare water phase carrier, immediately cool to 2-8 ℃ for standby, then, in the independent 5 ℃ low temperature environment, freeze-dried polypeptide powder is slowly added into pre-cooled phosphate buffer according to the proportion of 1mg / mL, stirring and dissolving, prepare polypeptide mother liquor, then, polypeptide mother liquor is stirred with the above-mentioned standby water phase carrier, after mixing evenly, the final solution is filled and sealed, and finally using high-temperature steam sterilization method is handled.
