Abstract
The invention discloses a kind of snap frozen case, including refrigerated container and liquid nitrogen bottle, the refrigerated container is the cylindrical structural of open at one end, upper end outer wall forms vavuum pump connector, lower end outer wall forms equipment connection port, and upper surface is outwardly formed flange, and flange upper surface forms annular groove；The liquid nitrogen bottle bottleneck end is outwardly formed connected unit, and connected unit lower surface forms annular convex ring；Liquid nitrogen bottle body is placed in refrigerated container；It is bolted between flange and connected unit.The operation evacuated in quick processing system abnormal accident can be reached using present invention evacuation, it is not necessary to the time for waiting conventional container to freeze, save the quality time of process accident problem, small volume and less weight of the present invention, also allow for moving, it is more extensive available for narrow space, use range.
Description
Technical field
The invention belongs to the device of refrigerated container, and in particular to a kind of snap frozen case.
Background technology
In to system or equipment evacuation, it is often necessary to by refrigerated container by evacuation process, system or equipment
In residual substance be refrigerated to container, without being rejected in air, so as not to pollution environment.Conventional refrigerated container have 24L,
Several models such as 20L, 50L, refrigerated container also need to enlightening watt bottle, container are placed in one, and pour into liquid nitrogen, wait container fully cold
After jelly, it can come into operation.Experience is drawn by long-term use, and because evacuated vellel volume is big, the reason such as the area that is cooled, container is cold
Freeze to condition needs time of at least more than 2 hours for using can be reached, therefore as being badly in need of carrying out by cold system or equipment
When freezing the evacuation of container, it can not carry out.
The content of the invention
The present invention proposes that the purpose is to provide a kind of snap frozen in order to overcome shortcoming present in prior art
Case.
The technical scheme is that：
A kind of snap frozen case, including refrigerated container and liquid nitrogen bottle, the refrigerated container are the circle of open at one end
Column construction, upper end outer wall form vavuum pump connector, and lower end outer wall forms equipment connection port, and upper surface is outwardly formed flange,
Flange upper surface forms annular groove；The liquid nitrogen bottle bottleneck end is outwardly formed connected unit, and connected unit lower surface forms convex annular
Ring；Liquid nitrogen bottle body is placed in refrigerated container；It is bolted between flange and connected unit.
The internal diameter of the refrigerated container is more than the external diameter of liquid nitrogen bottle.
The beneficial effects of the invention are as follows：
The operation evacuated in quick processing system abnormal accident can be reached using present invention evacuation, it is not necessary to wait tradition
The time of container freezing, the quality time of process accident problem is saved, small volume and less weight of the present invention, also allows for moving, can be used for
Narrow space, use range are more extensive.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Wherein：
The liquid nitrogen bottle of 1 refrigerated container 2
The equipment connection port of 3 vavuum pump connector 4
The groove of 5 flange 6
The bulge loop of 7 connected unit 8.
Embodiment
Snap frozen case of the present invention is described in detail with reference to Figure of description and embodiment：
As shown in figure 1, a kind of snap frozen case, including refrigerated container 1 and liquid nitrogen bottle 2, the refrigerated container 1 are
The cylindrical structural of open at one end, upper end outer wall form vavuum pump connector 3, and lower end outer wall forms equipment connection port 4, upper surface
Flange 5 is outwardly formed, the upper surface of flange 5 forms annular groove 6；The bottleneck end of liquid nitrogen bottle 2 is outwardly formed connected unit 7, connection
The lower surface of platform 7 forms annular convex ring 8；The body of liquid nitrogen bottle 2 is placed in refrigerated container 1；Pass through bolt 9 between flange 5 and connected unit 7
Connection.
The internal diameter of the refrigerated container 1 is more than the external diameter of liquid nitrogen bottle 2.
