The each assembly principle analysis of the utility model:
The design of liquid nitrogen inlet port is on the top of chuck, when the amount of liquid nitrogen added, after the temperature of desired reduction can be reached, just can be easy to close liquid nitrogen inlet port valve, extract liquid nitrogen without the need to continuing, not needing used time valve-off, and be arranged on bottom, valve is in the state of siege of ultralow temperature always, can generate one deck ice of great thickness, affect valve switch;
Atmospheric vent lower end is equipped with gas check valve, is prevented air and steam from entering, and maintains anhydrous and oxygen-free environment in still, can reduce nitrogen pressure in still again, safe and practical;
The outer nitrogen outlet of still can according to the response situation of reactor, and the whereabouts after regulating liquid nitrogen to change into nitrogen is at any time safe and reliable, except this, the nitrogen that liquid nitrogen can be changed into again sends into reactor, maintains the anhydrous and oxygen-free environment in still, without the need to additionally using nitrogen, provide cost savings;
Before reaction, material feeding mouth with closure and liquid material charging aperture band valve in reaction, conveniently add materials (solid, liquid) before the reaction with in course of reaction, convenient and practical;
The reactor left side arranges liquid material charging aperture in reaction near the position of paddle, and mounted valve, and then nitrogen outlet in still is set, temperature control sleeve pipe is finally set, liquid material charging aperture in reaction is arranged on the position near paddle, and being conducive to material can fully mix.
In equipment operation, stir driving arrangement and comprise motor, shaft, paddle, shaft connects paddle, and the rotor of motor connects shaft by shaft coupling; The shape of described kettle top and bottom is all spheroid-like.

In figure: 1. liquid material charging aperture, 10. gas check valve, 11. atmospheric vent, 12. temperature control sleeve pipes, 13. three-way valves in material feeding mouth, 8. vacuum orifice band valve, 9. reaction before nitrogen outlet, 7. reaction in paddle, 2. baiting valve, 3. still chuck, 4 liquid nitrogen inlet ports, 5. still outer nitrogen outlet, 6. still.
Detailed description of the invention
Make those skilled in the art understand the technical solution of the utility model better, below in conjunction with detailed description of the invention and accompanying drawing, the utility model is described in further detail.
Embodiment 1: a kind of ultralow temperature anhydrous and oxygen-free reactor, this reactor device is made up of liquid material charging aperture 9, gas check valve 10, atmospheric vent 11, temperature control sleeve pipe 12, three-way valve 13 in material feeding mouth 7, vacuum orifice band valve 8, reaction before nitrogen outlet 6, reaction in kettle, paddle 1, baiting valve 2, still chuck 3, liquid nitrogen inlet port 4, the outer nitrogen outlet 5 of still, still.Described paddle 1 is fixed on position, middle in kettle, and its top is connected with motor shaft.Described drain hole 2 is arranged on position, middle, kettle bottom.Described still chuck 3 prolongs drain hole 2 both sides and is surrounded by kettle and be fixed on kettle.The described top of liquid nitrogen inlet port 4 on the right side of still chuck, and be provided with valve.On the right side of reactor near paddle 1 position set gradually atmospheric vent band valve 11, vacuum orifice band valve 8, reaction before material feeding mouth with closure 7, in atmospheric vent 11 lower end, gas check valve is housed.Liquid material charging aperture band valve 9 in reaction is set gradually near the position of paddle 1, nitrogen outlet 6 in still, temperature control sleeve pipe 12 on the reactor left side.The outer nitrogen outlet 5 of the still arranged is connected on still chuck 3 by three-way valve, and in still, the outer part of nitrogen outlet 6 still is connected by the outer nitrogen outlet 5 of three-way valve 13 and still.
Concrete operation process is as follows: first check air-tightness before the reaction, after gas leakage, required material is all joined reactor from the front material feeding mouth 7 of reaction, close seal cover, open and stir, open vacuum orifice 8 valve, vacuumize, open liquid nitrogen inlet port 4 valve, by the amount of liquid nitrogen that pump suction needs, after in still, vacuum reaches peak, gas three-way valve 13 is turned to nitrogen outlet 6 in still, now nitrogen enters in reactor, open the valve of atmospheric vent 11, now because there is gas check valve 10, air can not enter in still from still, after nitrogen is full of, unnecessary nitrogen can be discharged from atmospheric vent 11, for the liquid nitrogen freezed, after completing refrigeration, change into nitrogen, maintain anhydrous and oxygen-free, continue to play a role, play two effect obtained at one stroke, cost can be saved, and it is safe and practical.
