Plate type electrode heating device

Abstract

The invention relates to a plate type electrode heating device and belongs to the technical field of heat treatment. The plate type electrode heating device comprises a heating barrel, a blind plate,a junction box, a power line, a water inlet and an exhaust port. The blind plate is arranged at a barrel opening of the heating barrel to isolate the heating barrel from the junction box. The power line extends out from the junction box. The blind plate is detachably connected with the heating barrel. The heating device further comprises a heating electrode. The blind plate is provided with an electrode insertion port and the exhaust port. The barrel opening of the heating barrel faces upwards. The heating electrode is connected with the blind plate through the electrode insertion port in theblind plate. The heating electrode is arranged inside the heating barrel. The power line is connected with the electrode insertion port in the junction box. The water inlet is arranged on the lower middle part of the sidewall of the heating barrel and is connected with a water inlet pipe. The plate type electrode heating device has the characteristics that the heating speed is high, heated liquidin the heating barrel cannot leak into the junction box, and the safety performance is high.

Description

technical field [0001] The invention belongs to the technical field of heat treatment, and relates to a heating device, in particular to a plate-type electrode heating device. Background technique [0002] Electrode heating uses the principle of anion and cation conduction in the ionic solution to directly heat the heating liquid through the electrode, eliminating the need to heat the intermediate medium first and then heat the solution when heating the heating liquid through the resistance wire in the traditional resistance wire heating. The process helps to improve the heating efficiency. At the same time, when there is no liquid in the heating barrel, the electrode heating device will automatically cut off the power, and there will be no dry burning phenomenon, which increases safety. [0003] Electrode heating is a commonly used heating method in the prior art. For example, the invention patent with the authorized announcement number "CN208382540" discloses an electrode ...

Problems solved by technology

[0004] However, due to the small relative area between each electrode rod, the directly heated solution is less, and the heating speed is slow. At the same time, because the shell is on the upper part of the junction box, and the connection hole is immersed in the heating solution, it is easy to damage the shell and the junction box. The sealing effect of the room will cause water leakage and cause safety accidents
