Description

Technical Field

[0001] The utility model relates to the technical field of multi-channel reactor product heat preservation and separation equipment, in particular to an openable experimental heat preservation box device. Background Technique

[0002] In the experiment process of a multi-channel reactor, the existing technology for the pipeline from the reactor outlet to the receiving tanks such as heat traps and cold traps is to use heating tapes for heat preservation or heat-insulating cotton for constant temperature of the pipeline. Since the heating tapes are wound around the pipeline, for small pipelines, the winding may become loose, or it may not fully fit the pipeline, and it cannot uniformly heat every part of the pipeline. Therefore, the phenomenon of local overheating often occurs, and the temperature monitored by the thermocouple for temperature measurement at the detection position is not the temperature of the entire pipeline, which leads to deviation in the temperature control of the pipeline and further affects the stability of the experiment.

[0003] Since the pipeline is wound with heating tapes, during the maintenance process, the heating tapes need to be removed first, and each operation is relatively cumbersome. Moreover, after the heating tapes are wound, the pipeline becomes bulky, and the pipeline layout cannot be intuitively shown, nor can every detail of the pipeline be clearly observed. In addition, the heating tapes are prone to aging and deformation during long-term use, and their surfaces are also easily contaminated with dust, which is not easy to clean and affects the aesthetics of the equipment. Therefore, this application proposes an openable experimental heat preservation box device. Summary of the Invention
