Description
Technical field
This utility model relates to a kind of storage tank, especially a kind of cryogenic liquid storage tank, belongs to technical field of energy equipment.
Background technology
Cryogenic liquid storage tank is a kind of special storage and the jacket type vacuum insulation pressure of supply low-temperature liquefaction liquid at present
Container, is widely used in commercial production, hospital and daily life.But owing to cryogenic liquid has relatively low boiling point, bigger
The hazard properties such as dilatancy, stronger hygroscopicity, Strong oxdiative and explosive.Owing to China's cryogenic equipment is started late, it is right to add
Cryogenic equipment operator training is less, and the safe handling of cryogenic equipment is known little about it by operator, so China is often sent out
There is casualty accident in using in raw cryogenic equipment, and causes the biggest loss to China's manpower and materials.
Utility model content
For above-mentioned the deficiencies in the prior art, this utility model provides a kind of cryogenic liquid storage tank reliably.
For achieving the above object, the technical solution adopted in the utility model is: a kind of cryogenic liquid storage tank, including bearing,
Interior tank body, outer tank body, inlet and liquid outlet, the diameter of described interior tank body and be highly slightly less than described outer tank body, and described in
Tank body is positioned at the inside of described outer tank body, forms a vacuum space, described feed liquor between described interior tank body and described outer tank body
Mouth is connected with upper pipe, down tube, and what described upper pipe was airtight is linked into the upper top of described interior tank body, the access that described down tube is airtight
To the bottom of described interior tank body, described interior tank body top seals and picks out a blow-down pipe, and the exit of described blow-down pipe is provided with
Atmospheric valve, described liquid outlet is positioned at the end of drain pipe, airtight being linked in described inner canister body of the other end of described drain pipe
The bottom in portion, described drain pipe connects and has return pipe, and return pipe connects evacuated tube, the access that the other end of described return pipe is airtight
To the top of described interior tank interior, the described evacuated tube other end in the morning exposes in atmosphere.
As preferably, it is filled with adiabator in the vacuum space between described interior tank body and described outer tank body, to reach
Preferably insulation effect.
As preferably, it is connected between described upper pipe and described down tube and has communicating pipe, can balance between Shangguan and down tube
Hydraulic pressure, in more preferable injection cryogenic liquid to inner canister body.
As preferably, described upper pipe, down tube, return pipe, drain pipe are mounted on two gate valves, play more reliable closedown
With unlatching effect.
As preferably, described evacuated tube being provided with a gate valve, the air pressure of evacuated tube afterbody is less, only need to install one
Gate valve.
This utility model convenient transportation, save the energy, safe and reliable, ensure that purity, adaptability are big, quality is high, capacity is big,
Heat-insulating property is good, and the every profession and trade in national economy activities such as industry, agricultural, national defence and scientific researches is widely used, significant.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1: a kind of cryogenic liquid storage tank, including bearing 1, interior tank body 2, outer tank body 3, inlet 4 and liquid outlet
5, the diameter of described interior tank body 2 and be highly slightly less than described outer tank body 3, and described interior tank body 2 is positioned at described outer tank body 3
Portion, forms a vacuum space between described interior tank body 2 and described outer tank body 3, described inlet 4 is connected with upper pipe 8, down tube 9
Logical, the upper top being linked into described interior tank body 2 that described upper pipe 8 is airtight, what described down tube 9 was airtight is linked into described interior tank body
Bottom, described interior tank body 2 top seal pick out a return pipe 12, the exit of described return pipe 12 is provided with atmospheric valve 6, described in go out
Liquid mouth 5 is positioned at the end of drain pipe 14, and what the other end of described drain pipe 14 was airtight is linked into the end within described interior tank body 2
End, described drain pipe 14 connects and has return pipe 12, and described return pipe 12 connects evacuated tube 13, the other end of described return pipe 12
Airtight is linked into the top within described interior tank body 2, and described evacuated tube 13 other end in the morning is exposed in sky liquid.Described inner canister
It is filled with adiabator in vacuum space between body 2 and described outer tank body 3, more preferable insulation effect can be reached.On described
It is connected between pipe 8 with described down tube 9 and has communicating pipe 10, balance the hydraulic pressure in described upper pipe 8 and described down tube 9.Described upper pipe 8,
It is mounted on two gate valves 7 on down tube 9 return pipe 12, drain pipe 14, reaches more reliable closedown and opening.Described evacuated tube
One gate valve 7 is installed on 13.
This utility model in use, is filled with cryogenic liquid from inlet 4, and cryogenic liquid enters difference after inlet 4
Entering in interior tank body 2 by upper pipe 8 and down tube 9, upper pipe 8 enters from the top of interior tank body 2, and down tube 9 is entered from interior tank body lower part
Entering, can balance the hydraulic pressure in interior tank body 2, make to be filled with liquid velocity faster, the time faster, connects one between upper pipe 8 and down tube 9
