The purpose of this utility model is achieved in that a kind of small-sized cryogenic liquid storage tank, comprise inner barrel, inner core lower seal head and inner core upper cover, inner core lower seal head and inner core upper cover are closed respectively and are welded on inner barrel lower end and upper end, inner barrel, inner core lower seal head and inner core upper cover are coated with heat insulation layer, inner core upper cover top is provided with charging joint, inner core lower seal head is provided with liquid in-out pipe, base plate is provided with below described inner core lower seal head, support tube is provided with between base plate and inner core lower seal head, sandwich shell is provided with outside heat insulation layer, some reinforcement angle steel are welded with inside sandwich shell, expanded perlite is filled up in gap between sandwich shell and heat insulation layer.
In the utility model, be welded with some reinforcement angle steel inside sandwich shell, can reinforing function be played, strengthen angle steel also to play the role of positioning simultaneously, ensure the gap uniformity between heat insulation layer and sandwich shell, after filling up expanded perlite, expanded perlite thickness can be made even, and heat insulation and preservation effect is good.Compared with prior art, the utility model structural strength is large, manufactures simple, safe and convenient to use.This device can be used for filling liquid oxygen, liquid nitrogen or NLG.
Filling for being convenient to further, described charging joint is connected with feed and exhaust tube and spill pipe, feed and exhaust tube is inserted into the inner bottom part of inner core lower seal head from above, and the lower end of spill pipe is arranged on inner barrel top.Be filled with corresponding liquefied gas at low temp by feed and exhaust tube, when liquid level arrives the lower nozzle position of spill pipe, liquid starts to enter spill pipe, and overflows from spill pipe, and it ensures that the liquid loaded is unlikely to too much.
Feed and exhaust tube can be fixed well during for ease of installing, be provided with inner support inside described inner core lower seal head, inner support is provided with bell-mouthed guiding element, and described feed and exhaust tube lower end is through described guiding element.Guiding element play the guiding role, and makes feed and exhaust tube be inserted on inner support smoothly.
For ease of lifting, described sandwich shell top is provided with hanger.
Ensure that inner barrel obtains good support for progressive, between sandwich shell and inner barrel upper outside, be provided with radial supporter.
As further improvement of the utility model, described radial supporter and support tube are made up of glass fibre reinforced plastic material.Glass fibre reinforced plastics adopts light, safety, with low cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein, 1 base plate; 2 support tubes; 3 inner core lower seal heads; 4 inner barrels; 5 sandwich shells; 6 strengthen angle steel; 7 radial supporters; 8 inner core upper covers; 9 feed and exhaust tubes; 10 charging joints; 11 hangers; 12 spill pipes; 13 expanded perlites; 14 guiding elements; 15 inner supports, 16 heat insulation layers.
