AI Technical Summary

Technical Problem

Existing cryogenic storage tanks are prone to pressure and liquid level fluctuations during liquid inlet and outlet processes, which affect the normal liquid supply pressure.

Method used

A multi-layered buffer sleeve is installed at the inlet and outlet of the storage tank. The buffer sleeve consists of a first, second and third fine sand mesh layer arranged sequentially from the inside to the outside. The mesh size of the liquid permeable holes decreases layer by layer. The outer surface of the buffer sleeve is spherical or multiple planes. The liquid permeable holes are used for buffering and diverting liquid.

Benefits of technology

It effectively reduces the impact force when liquid enters and exits, reduces liquid fluctuations in the storage tank, avoids pressure fluctuations in the storage tank, ensures stable liquid supply, and has the function of filtering impurities.

Abstract

The application discloses a low-temperature storage tank with stable liquid inlet and outlet, and relates to the technical field of storage tanks, which comprises a storage tank, a liquid outlet and a liquid inlet are arranged at the bottom of the storage tank, a buffer sleeve is arranged on the liquid outlet and the liquid inlet, and a plurality of liquid-permeable holes are arranged on the buffer sleeve; when liquid is input into the storage tank, the liquid enters the storage tank through the plurality of liquid-permeable holes on the buffer sleeve at the liquid inlet, so that the impact force when the liquid enters is reduced, and the effect of buffering and shunting is achieved; when the liquid in the storage tank is output, the liquid in the storage tank enters the liquid outlet through the plurality of liquid-permeable holes on the buffer sleeve at the liquid outlet, the liquid from different liquid-permeable holes converges to the liquid outlet, and then is discharged from the storage tank, so that the problem of liquid supply pressure fluctuation when the storage tank is filled with liquid is effectively avoided.
