<p>The present invention relates to a cryogenic insulation storage tank and, more specifically, to a cryogenic insulation storage tank, which is configured to form a liquid transmission line that transfers a cryogenic liquid stored in the inside to a supplier such that the liquid transmission line can be extended from an upper part of the inside of an internal tank to a lower part, and to suck and transfer the cryogenic liquid in a siphon method to prevent an introduction of foreign substances present on the bottom of the internal tank when the cryogenic liquid is sucked and transferred through the liquid transmission line, thereby transferring the cryogenic liquid in a pure state to the supplier and preventing a failure of a valve caused by foreign substances, and which may effectively prevent an introduction of foreign substances by positioning a suction port of the liquid transmission line to be spaced apart from the bottom of the internal tank by a predetermined height, and which even when a cryogenic liquid is continuously sucked and transferred through the liquid transmission line, since a cryogenic fluid more than a predetermined height remains in the internal tank, requires no cooling down of the internal tank upon refilling the cryogenic liquid, thereby reducing filling time and cost of the cryogenic liquid.</p> |
