Description
Technical field
Chemical liquid preservation field is the utility model is related to, particularly a kind of thermos bottle type liquid nitrogen container.
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, therefore in laboratory operation, technical staff generally first pours into liquid nitrogen in thermos bottle, then is poured into and grinds
Alms bowl, but thermos bottle has a defect, its bottleneck can be frozen in after liquid nitrogen cryogenics, and lid is just not easy to open after covering.
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 thermos bottle type.
The purpose of this utility model can be realized by following technical proposal：A kind of thermos bottle type liquid nitrogen container, its feature exist
In it includes body, bottom of bottle, inner bag and bottle stopper, and the bottle mouth position of body sets acuminous water conservancy diversion bottle neck, described body and bottom of bottle
The relative folding of energy, inner bag top connection neck tube, the side wall of the neck tube are provided with some embedding grooves axially opened up along neck tube
One, described bottle stopper includes holding part and extension, the described extension diameter extension equal, described with the caliber of neck tube
Side wall is provided with the embedding groove two of corresponding above-mentioned embedding groove one, is provided with pail in described inner bag, the shadoof of described pail is clipped in
In embedding groove one and embedding groove two.
In a kind of above-mentioned thermos bottle type liquid nitrogen container, the height and body that the inner bag is superimposed with neck tube are contour, described
It is tightly connected between inner bag and neck tube by an adapter ring.
In a kind of above-mentioned thermos bottle type liquid nitrogen container, the holding part diameter of the bottle stopper is more than extension diameter.
In a kind of above-mentioned thermos bottle type liquid nitrogen container, height that described inner bag is superimposed with neck tube is 18cm, 21cm,
Tetra- specifications of 23cm, 25cm.
In a kind of above-mentioned thermos bottle type liquid nitrogen container, described body sidepiece is provided with a handle.
Compared with prior art, the utility model is easy to laboratory to use, and is easy to topple over and lifts, while inner bag and neck tube
Structure is identical with the height specification of common thermos bottle, thus the body of the utility model can applying hot water bottles shell replace,
Production cost is saved.
