Description
Technical field
Chemical liquid preservation field is the utility model is related to, particularly a kind of liquid nitrogen container of heat-preserving bucket type.
Background technology
Liquid nitrogen container generally can be divided into two kinds of liquid nitrogen container, liquid nitrogen transfer cask.Hold-up tank is mainly used in the quiet of indoor liquid nitrogen
Storage is put, long distance transportation use should not be made in the operating condition；Liquid nitrogen transfer cask has been made special to meet the condition of transport
Aseismatic design.
We mainly use liquid nitrogen container when laboratory uses.
Liquid nitrogen container is mostly aluminium alloy or stainless steel making, two layers inside and outside point.Specific component is as follows：
1st, shell：One layer is shell outside liquid nitrogen container, and its top is tank mouth.
2nd, inside groove：Space in liquid nitrogen container internal layer is referred to as the aluminium alloy of inside groove, generally corrosion resistance, and the bottom of inside groove has
Base, cylinder is carried for fixation, liquid nitrogen and sample can be stored in inside groove.
3rd, interlayer：Interlayer refers to the space of two interlayers inside and outside tank.In vacuum state.The purpose being evacuated is to promote tank
The heat-insulating property of body, while heat-insulating material and adsorbent are housed in interlayer.
4th, neck tube：Neck tube is typically glass-reinforced plastic material, two layers of connection by inside and outside, and maintains certain length, in neck tube
Around and bottom interlayer adsorbent is housed.The eck design at top is special, and its structure should have hole to discharge liquid nitrogen vaporization
Nitrogen out, to ensure safety, there is heat-insulating property again, to reduce the amount of vaporization of liquid nitrogen as far as possible.
5th, Gai Sai：Lid plug is made up of the plastics of excellent heat insulating performance, to prevent the evaporation of liquid nitrogen, while the fixed hand for carrying cylinder
Handle.
6th, pail：Carry cylinder to be placed in tank inside groove, wherein tubule can be stored.The handle for carrying cylinder is hung on eck, is filled in lid
Fix.
Existing liquid nitrogen storage jar structure is crossed as heaviness, (is similar to what we had a meal taking liquid nitrogen to make it into mortar
Bowl) in it is inconvenient.
Utility model content
The purpose of this utility model is to be directed to existing above mentioned problem, there is provided a kind of liquid nitrogen container of heat-preserving bucket type.
The purpose of this utility model can be realized by following technical proposal：A kind of liquid nitrogen container of heat-preserving bucket type, its feature
It is, it includes ladle body, the inner bag of tubular, middle cover, upper lid, and the ladle body is highly not higher than 40cm, and the inner bag is located at bucket
In body, middle cover is provided with the bung of ladle body, is connected with neck tube below middle cover, the lower section of neck tube is provided with terminal pad, described neck
Pipe and terminal pad are in ladle body, and described connection plate edge is provided with groove ring, and the top edge of inner bag is inserted in groove ring, described
Middle cover, neck tube, terminal pad are fixedly connected, and the side of the ladle body is provided with switching clinching, during described switching clinching can be pressed in
Between the side of covering and middle cover and ladle body are fixed, upper lid is provided with above described middle cover, upper cover includes top and extension
Portion, described extension diameter are equal with the caliber of neck tube.
The side wall of the neck tube is provided with some embedding grooves one axially opened up along neck tube, and described extension side wall is set
There is the embedding groove two of corresponding above-mentioned embedding groove one, be provided with pail in described inner bag, the shadoof of described pail is clipped in embedding groove
One and embedding groove two in.
Buffer stopper is lined between the ladle body and inner bag.
Compared with prior art, the utility model is easy to laboratory to use, and is easy to topple over and lifts, while the knot of middle cover
Structure can be placed in usual heat preservation dinner flask and directly reequip, and can be that equipment saves fund.
