Segmented plug-in type heating rod

Abstract

The present invention relates to an electric heating device for high-heat flow liquid, in particular, a segmented plug-in type heating rod. The segmented plug-in type heating rod of the invention comprises a shell, a heating body disposed in the inner cavity of the shell, a cover plate flange sheet covering the heating body, and a junction box connected with the heating body through the cover plate flange sheet; and the heating body comprises a split tail end column, split heating columns and a split cold end lead column, wherein the split tail end column and the split cold end lead column areconnected with each other through one or a plurality of the split heating columns. According to the segmented plug-in type heating rod of the invention, the split heating columns are connected with one another in series end to end in a split manner, and the split tail end column and the split cold end lead column are connected with each other, and therefore, the heating function of an integratedheating rod in the prior art can be realized; the heating rod of the invention is different from the integrated heating rod in the prior art in that the heating rod of the invention can be installed in a split manner, and therefore, requirements for installation environments can be decreased, the heating rod of the invention can be maintained in a segmented manner, so that maintenance is easier, and maintenance and use costs are decreased.

Description

technical field [0001] The invention relates to an electric heating device for liquid with high heat flow, in particular to a section-inserted heating rod. Background technique [0002] In industrial applications, because many media stored in containers or tanks need to be heated to prevent solidification, or to maintain high temperature to maintain their performance, the container, tank or medium body needs to be heated indirectly or directly. [0003] Due to different application requirements, many tanks or containers for storing media are installed indoors and the storage space is relatively compact. It is very inconvenient or impossible to install the direct-insert heating rod. Before the tank or container is installed indoors, pre-installation It is difficult to disassemble, repair and replace it when it is installed, and if it breaks down after the installation is completed or when it is used, it is necessary to increase the area of ​​the tank or container storage poin...

AI Technical Summary

Problems solved by technology

[0006] 1: Installation is inconvenient; if the original heating rod has a total length of 3m and an internal heating core length of 2.6m, it is necessary to leave a space of at least 3m at the place where it is installed. If it is installed vertically, tools such as a crane are required to install it indoors. After installation, it will be very inconvenient to maintain and disassemble in the future, and even impossible to maintain

[0007] 2: The maintenance cost is high; if there is a weak point in the overall heating core that causes the equipment to fail to work normally, the entire core component needs to be removed, repaired or even replaced. Lost and increased cost of repairs and worse parts
