Abstract

Scope: in cryogenic technology, in particular in cryostats and Dewar vessels for storing biological preparations in liquid nitrogen. SUMMARY OF THE INVENTION: In the lower part of the inner wall of a thermally insulated vessel, circular and annular trapezoidal recesses are made to accommodate the adsorbent. 1 ill.

Description

. The invention relates to cryogenic technology, in particular to vessels for storing and transporting biological preparations in a cooling medium.

The purpose of the invention is to increase the efficiency of the adsorbent.

The invention is shown in the drawing.

The vessel consists of an outer wall 1 of a thermally insulated container with handles for carrying 2 and a vacuum unit 3 and an inner wall 4 with a round recess

5 in the bottom and annular recess

6 at the bottom of the shell. The outer and inner walls are connected in the upper part of the vessel by a fiberglass neck 7, six cassettes are mounted in a suspended state (uniformly around the neck circumference) for the upper end part of the vessel, consisting of pendants 8 with hooks 9 and cylindrical glasses 10. In the cavity formed by annular and circular recesses of the inner wall of the vessel, granular adsorbent 11 is filled in. From the side of the evacuated space of the vessel, the cavities are closed by a mesh partition 12.; As a partition material, cryosilic fiberglass can be glued with glue or a metal mesh soldered with appropriate solder. In the interwall space of the vessel, layers 13 of screen-vacuum thermal insulation are placed.

The operation of the vessel is simple and does not require special removal.

The implementation of the cavities for accommodating the trapezoidal adsorbent (s) of the cell-shaped cross-section promotes the contact of more adsorbent with the vessel wall washed by the cryoproduct. The division of the depression into two contributes to the same: central and annular. Thus, the maximally developed surface of the adsorbent was obtained, which constantly works in the most efficient cooling mode when the maximum absorption capacity of the adsorbent is manifested. Increasing the efficiency of the adsorbent improves the thermal insulation properties of the vessel.

The presence of recesses of the trapezoidal section directed by the large side of the trapezoid into the tank allows the recesses to play the role of dampers of the oscillations of the cryogenic Product during transportation of vessels in poor roads, rural areas, where most often

In addition, the annular recess reduces the amplitude of swinging of biofood cassettes, suspended by the neck, during transport during transport, which improves the safety of the product loading and unloading mechanism stored in the cassette.
