Description
Technical Field
The present invention relates to a heat storage device electrode.
Background
In the prior art, the leading-out part of the heating resistance wire of the heat storage device needs to mill a half of resistance material at the end part and then insert into the conductive connecting sleeve, and then is fastened and compressed by screws, so that the resistance material is easy to soften in the heating process due to the high temperature in the heater, the pressure is insufficient due to the reuse after cooling, the problems of poor contact, unstable conductive performance, incapability of meeting the requirement on the heating effect and the like also exist, and the service life of the heater is influenced.
Disclosure of Invention
The invention aims to solve the technical problem of providing a heat storage device electrode which is reliable in connection, long in service life and high in heating efficiency.
The heat storage device electrode comprises a substrate connected with an external electric conductor, and a connecting sleeve is welded on the substrate, and is characterized in that: the connecting sleeve is welded and fixed with the substrate, a connecting hole for the resistance rod to penetrate is formed in the middle of the connecting sleeve, a half part of the connecting sleeve is milled to be empty and exposed out of the connecting hole, and a half part of the resistance rod which is exposed out of the connecting hole and a milling plane of the connecting sleeve form a smooth curved surface through surfacing welding;
the rear end of the resistance rod and the connecting sleeve are provided with a welding area;
the connecting sleeve is made of copper.
According to the heat storage device electrode, the connecting sleeve is welded on the substrate, the rear section of the connecting sleeve is milled to be empty and exposed out of the middle connecting hole, then the resistor rod is inserted, the surface of the resistor rod is welded with the rear section of the connecting sleeve through surfacing, and the resistor rod can be firmly connected without being damaged; the rear end of the resistance rod and the connecting sleeve are subjected to fusion welding to further enhance the connecting strength, the connection is reliable, the electric conductivity is stable, the heating efficiency is high, and the service life of the heater is long.
