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, should not be used in the operating condition as long distance transportation；Liquid nitrogen transfer cask has made special to meet the condition of transport
Aseismatic design.
We mainly use liquid nitrogen container when laboratory is used.
Liquid nitrogen container is generally 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, carries cylinder 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 being equipped with heat-insulating material and adsorbent in interlayer.
4th, neck tube：Neck tube is typically glass-reinforced plastic material, will be connected for inside and outside two layers, and maintains certain length, in neck tube
Around and bottom interlayer be equipped with adsorbent.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 had a meal taking liquid nitrogen to make it into mortar similar to us
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.
The content of the invention
The purpose of the present invention is that there is provided a kind of liquid nitrogen container of thermos bottle type for existing above mentioned problem.
The purpose of the present invention can be realized by following technical proposal：A kind of thermos bottle type liquid nitrogen container, it is characterised in that it
Including body, bottom of bottle, inner bag and bottle stopper, the bottle mouth position of body sets acuminous water conservancy diversion bottle neck, described body and bottom of bottle energy phase
To folding, neck tube is connected above inner bag, the side wall of the neck tube is provided with some embedding grooves one axially opened up along neck tube, institute
The bottle stopper stated includes holding part and extension, described extension diameter extension side wall equal with the caliber of neck tube, described
Pail is provided with embedding groove two provided with the above-mentioned embedding groove one of correspondence, described inner bag, the shadoof of described pail, which is clipped in, to be inlayed
In groove one and embedding groove two.
In a kind of above-mentioned thermos bottle type liquid nitrogen container, the height that the inner bag is superimposed with neck tube and body 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 of the bottle stopper is with diameter greater than extension diameter.
In a kind of above-mentioned thermos bottle type liquid nitrogen container, the height that described inner bag is superimposed with neck tube be 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.
A kind of replacement method of thermos bottle type liquid nitrogen container inner bag：Characterized in that, it comprises the following steps：
A, the bottom opening by common vacuum bottle shell；
B, adapter ring between inner bag and neck tube is tightly connected；
It is plunged into after C, inner bag and neck tube connection in vacuum bottle shell, the mouth of pipe of neck tube is in position of bottleneck, then the bottom of
Lid is covered.
Compared with prior art, the invention is easy to laboratory to use, it is easy to topples over and lifts, while inner bag and neck-pipe structure
It is identical with the height specification of common thermos bottle, thus the body of the invention can applying hot water bottles shell replace, saved life
Produce cost.
