This utility model provides a phase-introducing
electrode connection structure and an
electrode boiler, relating to the field of
electrode boiler technology. It includes a phase-introducing electrode, a
flange module, and a
pipe body. The
flange module includes an upper
flange, a lower flange, a flange bolt
assembly, threaded fasteners, and a fastening ring. The upper and lower flanges are fitted onto the phase-introducing electrode. An annular
mating groove is provided on the side of the lower flange opposite to the upper flange. The
mating groove is used for inserting the
pipe body and installing the fastening ring. The threaded fasteners are used to fix the fastening ring. When the fastening ring is installed, it compresses the
pipe body to make it fit against the inner wall of the
mating groove. By setting the mating groove, the lower flange and the pipe body are connected using threaded fasteners, eliminating the need for
welding and simplifying the
welding process. This achieves high-efficiency connection and avoids quality problems caused by
welding inexperience or errors. After the lower flange is connected to the pipe body, the upper flange cooperates with the lower flange to fix the phase-introducing electrode.
