HEAT INSULATING CONTAINER FOR LOW-TEMPERATURE LIQUEFIED GAS PUMPS

The purpose is to provide a heat insulating vessel for a low temperature liquefied gas pump which increases adiabaticity of a lid structure and increases maintainability of a vacuum insulating layer. The heat insulating vessel (1) includes an inner tank (3) having a vertical axis and configured to a...

Beschreibung
Zusammenfassung:	The purpose is to provide a heat insulating vessel for a low temperature liquefied gas pump which increases adiabaticity of a lid structure and increases maintainability of a vacuum insulating layer. The heat insulating vessel (1) includes an inner tank (3) having a vertical axis and configured to accommodate low temperature liquefied gas, an outer tank (5) provided externally around the inner tank (3), and a low temperature liquefied gas pump (2) disposed inside the inner tank (3). The outer tank (5) has an outer tank upper part (5U) that is an upper end portion thereof, and an outer tank body (5L) other than the outer tank upper part (5U). A lid structure (6) having a heat-insulated structure detachably fitted into an upper part of the inner tank (3) is provided. The heat insulating vessel includes a first fastening part (19) configured to fasten with bolts a first flange () provided to upper ends of the inner tank (3) and the outer tank upper part (5U) to a second flange (16) provided to an outer circumferential part of the lid structure (6), and a second fastening part (24) configured to fasten with bolts a third flange (20) provided to an upper end of the outer tank body (5L) to a fourth flange (21) provided to a lower end of the outer tank upper part (5U). A vacuum insulating layer (4) is formed between the inner tank (3) and the outer tank (5).
