Novel insulation device of extraction tube of cryogenic pump box

Abstract

The invention discloses a novel insulation device of an extraction tube of a cryogenic pump box, and provides a high-universality insulation device with a pipeline located at the perforated position of a panel of a cryogenic pump box. The pipeline insulation problems that when a low-temperature pipeline is fed in and discharged out of a box, flexible compensation is insufficient, and the pipe penetrating portion of the box is cooled and frosted are solved. The novel insulation device of the extraction tube of the cryogenic pump box comprises a floating sealing sleeve, a hose clamp, a box insulation casing pipe, a foaming insulation material, a galvanized plate pipeline insulation barrel and a pipeline insulation material. The insulation device is in a conic barrel shape. The floating sleeve and the pipeline are locked through the hose clamp, the pipe can stretch and contact freely and is not limited, and the situation that the pipeline and the box panel are in direct contact, and consequently the panel is in low temperature to be frosted is avoided. The device has the advantages of being simple in structure, high in practicality, low in cost, safe in performance, convenient to mount and the like.

Description

technical field [0001] The invention relates to a novel heat preservation device for a lead-out pipe of a cryogenic pump box, which belongs to the technical field of structural design. Background technique [0002] Driven by the rapid development of my country's coal chemical and petrochemical industries, the air separation industry has developed rapidly. As an important part of air separation, cryogenic liquid pumps have seen a surge in market demand. Cryogenic liquid pumps, as sensitive dynamic equipment, have extremely high requirements on the load at the nozzle of the equipment. This new type of thermal insulation device for the outlet pipe of the cryogenic pump can also improve the insulation performance of the pump outlet pipeline on the premise of ensuring the insulation effect of the pipeline at the place where the casing passes through the pipe. The flexible state improves the pipeline stress compensation and provides a new solution to reduce the load of the pump no...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the shortage that the existing low-temperature pipeline is easy to run cold at the outlet position of the pump box and must be in fixed contact with the box panel, and provides a new insulation type of the outlet pipe, which is suitable for pump outlet pipelines of various calibers. The structure is simple, the insulation effect is good, and it provides favorable conditions for solving the outlet load of the cryogenic cryopump in the form of pipeline self-compensation
