Liquid nitrogen nozzle connection is stated, for introducing external high-pressure liquid nitrogen in shell；The diversion column is vertically arranged at the interior bottom of shell
Wall, and the upper end of diversion column is plugged in liquid nitrogen nozzle, the liquid nitrogen for spraying liquid nitrogen nozzle is guided to each evaporation blade；Respectively
Evaporate blade ring to be arranged around diversion column, and evaporate the bottom of blade and the inner bottom wall of shell connects, for liquid nitrogen and working face into
Row heat exchange；One end of the interface channel is connect with shell, and the other end of interface channel is connect with external negative pressure pump, is used for
The nitrogen generated after heat exchange in shell is discharged.
Further improvement lies in that: the evaporation blade has corner towards one end of diversion column.
Further improvement lies in that: the arc-shaped structure of the evaporation blade.
Further improvement lies in that: the diversion column is in conical structure.
Further improvement lies in that: the connection of the top of the interface channel and shell.
Further improvement lies in that: the delivery pipe penetrates shell from inside interface channel.
Further improvement lies in that: the high-pressure liquid nitrogen storage device is high-pressure liquid nitrogen tank.
The beneficial effects of the present invention are:
The present invention has broken the refrigeration modes of traditional single depended on pressure conduction, so that liquid nitrogen is passed through conveying with intracavitary high pressure
Pipe rushes liquid nitrogen through diversion column on nozzle to working face (the contact refrigeration group for getting to shell on evaporation blade after quickly rotating
The part knitted), nitrogen suction is gone out into refrigeration equipment by negative pressure pump after quick heat exchange, the chilling rate of system greatly improved
And freezing efficiency.
