Part of the body is provided with the gyro wheel, and jar bottom of personally experiencing sth. Part of the body is provided with the recess with rollers matching. The utility model provides a liquid nitrogen tank, this liquid nitrogen tank can use a straight section of thick bamboo to take the liquid nitrogen when the liquid nitrogen of storage is sufficient, can choose for use hang down evil trompil and to empty the liquid nitrogen when the liquid nitrogen is insufficient, and through just can audio -visually observing the liquid level position among the liquid nitrogen tank in the position of the rope on the observation liquid nitrogen tank surface, the gyro wheel bottom the liquid nitrogen tank has made things convenient for liquid nitrogen tank's removal.
Description
Technical field
This utility model is related to liquefied gass and contains device, more particularly, to a kind of liquid nitrogen container.
Background technology
At present, market has a lot of liquid nitrogen containers, facilitate user and use liquid nitrogen, but, also deposit for the user
Be inconvenient to the defect that uses at some, such as it is not easy to topple over liquid nitrogen it is impossible to intuitively when the liquid nitrogen of liquid nitrogen container storage is more
Observe the liquid level of liquid nitrogen, when the liquid nitrogen of storage in liquid nitrogen container is inadequate, be also not easy to topple over liquid nitrogen, liquid nitrogen container is difficult to be moved
Move etc..
Utility model content
This utility model, in order to solve the shortcoming of above-mentioned prior art, provides a kind of liquid nitrogen container, and this liquid nitrogen container can be square
Just take liquid nitrogen, can intuitively observe the liquid level situation of liquid nitrogen, liquid nitrogen container can be moved easily.
This utility model is realized in：A kind of liquid nitrogen container, including tank body, is arranged between the internal layer of tank body and outer layer
There is heat-insulation layer, the lid of this liquid nitrogen container is fixed with straight tube by connecting rod, is provided with liquid-level measurement device in liquid nitrogen container, tank body
Bottom is provided with perforate, and perforate is provided with port lid, and the bottom of tank body is provided with roller, and the bottom of tank body is provided with and is matched with roller
The groove closing.
Side wall and the bottom of described straight tube are detached, and connecting rod is connected with the bottom of straight tube, the side wall of straight tube bottom
Inner surface setting has outside draw-in groove, is matched with this draw-in groove in the bottom of straight tube, thus being embedded on the side wall of straight tube, straight tube bottom
Radius be less than straight tube sidewall cross-sectional maximum radius, and more than straight tube cross section least radius.
Described liquid-level measurement device is the ball float being connected with rope, and the length of rope is more than the height of tank body, tank body
The stopping means preventing rope from slipping are provided with outer surface.
Described perforate and port lid are threaded connection, and port lid is insulation material
With respect to prior art, the beneficial effects of the utility model are：
This utility model provides a kind of liquid nitrogen container, and this liquid nitrogen container can be taken using straight tube when the liquid nitrogen of storage is sufficient
Liquid nitrogen, can topple over liquid nitrogen from the perforate of low evil when liquid nitrogen is inadequate, by observing the rope on liquid nitrogen container outer surface
Position just can intuitively observe liquid level position in liquid nitrogen container, the roller of liquid nitrogen pot bottom facilitates the shifting of liquid nitrogen container
Dynamic.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
As shown in figure 1, a kind of liquid nitrogen container, including tank body 1, between the internal layer of tank body and outer layer, it is provided with heat-insulation layer, should
The lid 2 of liquid nitrogen container is fixed with straight tube 4 by connecting rod 3, is provided with liquid-level measurement device, the bottom setting of tank body in liquid nitrogen container
There is perforate 5, perforate is provided with port lid 6, the bottom of tank body is provided with roller 7, the bottom of tank body is provided with is matched with roller
Groove 8.
Side wall and the bottom of described straight tube are detached, and connecting rod 3 is connected with the bottom of straight tube, the side wall of straight tube bottom
Inner surface setting has outside draw-in groove 12, is matched with this draw-in groove in the bottom of straight tube, thus being embedded on the side wall of straight tube, straight tube bottom
The radius in portion is less than the maximum radius of straight tube sidewall cross-sectional, and the least radius more than straight tube cross section.
Described liquid-level measurement device is the ball float 9 being connected with rope 10, and the length of rope is more than the height of tank body, tank body
Outer surface on be provided with prevent rope slip stopping means 11.
Described perforate 5 and port lid 6 are threaded connection, and port lid 6 is insulation material.
During using, when the liquid nitrogen of storage in liquid nitrogen container is sufficient, scooped using the straight tube 4 being fixed on lid 2
Go out liquid nitrogen, because the side wall of straight tube is detached with bottom, connecting rod 3 is connected with the bottom of straight tube, in the side wall of straight tube bottom
Surface is provided with outside draw-in groove 12, is matched with this draw-in groove in the bottom of straight tube, thus being embedded on the side wall of straight tube, straight tube bottom
Radius be less than straight tube sidewall cross-sectional maximum radius, and more than straight tube cross section least radius, after scooping out liquid nitrogen, will
Straight tube wall, against container, is pressed downward lid 2, you can discharge liquid nitrogen, carries lid 2 upwards and just straight tube bottom can be embedded in straight tube wall
On, liquid nitrogen of can taking again.When the liquid nitrogen of storage in liquid nitrogen container is inadequate, can the sharp perforate leading to liquid nitrogen bottom take,
And port lid uses insulation material, perforate 5 and port lid 6 are threaded connection, and such structure ensure that the airtight of liquid nitrogen container
Property and heat insulating ability.Even if because the liquid nitrogen in liquid nitrogen container does not use also can volatilize, it is therefore desirable to liquid-level measurement device is detecting
Liquid level, but the temperature of liquid nitrogen is -196 DEG C, and general level sensor is all inapplicable, and this utility model is using being connected with rope
The 10 simple liquid-level measurement device of this structure of ball float 9 intuitively to observe liquid nitrogen liquid level, in order to prevent rope from slipping, in liquid nitrogen
Stopping means 11 are provided with the outer surface of tank.General operator is using can't fix a position during liquid nitrogen, but liquid
Very greatly it has not been convenient to mobile, tank base therefore of the present utility model is provided with roller 7 to nitrogen tank weight, and the bottom of tank body is provided with
The groove 8 matching with roller, pulls out roller 7 when needing mobile, when needing steadily to place liquid nitrogen container, roller 7 is backed up into recessed
In groove 8.
Embodiment described above, simply one kind of this utility model more preferably specific embodiment, the skill of this area
The usual variations and alternatives that art personnel are carried out in the range of technical solutions of the utility model are intended to be included in guarantor of the present utility model
In the range of shield.
