Modularized thermal insulation device

Abstract

A modularized thermal insulation device comprises a plurality of thermal insulation modules and connecting structures. Each thermal insulation module is composed of the four parts of a metal shell, a thermal insulation material, a cross-shaped structure and a plurality of sets of bolted connection through holes, each set of connecting structures is composed of nuts, a first gasket, a second gasket and bolts, the adjacent thermal insulation modules are matched with each other through a dislocated mode, and the thermal insulation modules and the outer wall surfaces of equipment and pipelines are compressed by adopting the bolts; aiming at some equipment and pipelines which need to be heated and thermal insulated and also need to be subjected to rapid natural convection cooling after the work of the equipment and the pipelines is completed, the thermal insulation device can ensure the integrity in the mounting and dismounting processes, and can also obviously improve the rapidness of mounting and dismounting; and the thermal insulation device adopts the connecting bolts so that close fit of the thermal insulation modules and the outer wall surfaces of the equipment and the pipelines can be ensured, the thermal insulation effect is greatly improved, and heating elements of the outer wall surfaces of the equipment and the pipelines can be prevented from being burned down due to the fact that the thermal insulation effect is bad.

Description

technical field [0001] The invention relates to the technical field of heat preservation devices, in particular to a modular heat preservation device. Background technique [0002] In industrial production and scientific research experiments, due to the large temperature difference between equipment and pipelines and their working environment, it is usually used to wind heating wires and wrap insulation cotton on the outer walls of equipment and pipelines to reduce heat loss and ensure relatively stable internal temperatures. The existing thermal insulation cotton wrapping method is only to wrap thermal insulation cotton on the outer wall of the equipment and pipes and paste it with aluminum foil tape.

AI Technical Summary

Problems solved by technology

The existing thermal insulation cotton wrapping method is only to wrap thermal insulation cotton on the outer wall of the equipment and pipes and paste it with aluminum foil tape. Not only is it difficult to ensure the integrity of the thermal insulation cotton during installation and disassembly, but also It is difficult to achieve a close fit effect on the wall surface. When the outer wall surface of the equipment and the pipe is wound with the heating wire for heating and insulation, the heating wire may be burned due to the poor insulation effect of the insulation cotton.

[0003] For some equipment and pipelines, heating and heat preservation and natural convection cooling need to be carried out alternately, which not only requires the control of the heating wire wound on the outer wall to work alternately, but also requires reciprocating installation and removal of the insulation cotton wrapped on the outer wall of the equipment and pipeline, if The wrapping method of conventional thermal insulation cotton not only has extremely low work efficiency, but also has a low utilization rate of the original thermal insulation material, resulting in a waste of resources. Moreover, when the heating wire is wrapped around the outer wall, the heating wire may be damaged due to the poor installation effect of the thermal insulation cotton. burn

For equipment and pipelines that require heating and heat preservation and natural convection cooling with the environment, in addition to controlling the alternate work of the heating wire on the outer wall, a heat preservation device that is easy to install and disassemble and can ensure heat preservation has not yet been disclosed.
