Abstract

The invention discloses an expansion electrode, which is applied to an aluminum foil linkage energizing device; the expansion electrode comprises: an electrode outer frame is provided with a plurality of metal wires to realize the conduction of an external power supply connecting the expansion electrode and the aluminum foil linkage energizing device; The electrode outer frame is provided with one or two electrode inner frames, and several metal wires extend to the top of the electrode inner frame; an electrode mesh is welded on the electrode inner frame, and the metal frame is connected to the electrode mesh for electrode reaction; a forced circulation distribution pipe It is arranged on the inner side and bottom of the outer frame of the electrode, and is connected to the electrolyte temperature adjustment tank of the aluminum foil linkage energizing device through a liquid inlet pipe, and the electrolyte in the electrolyte temperature adjustment tank is introduced into the expansion electrode; an electrode expansion adjustment member is arranged on the The outer side of the electrode outer frame is connected to the electrode outer frame and the electrode inner frame respectively, so as to realize the expansion and contraction of the expansion electrode. The beneficial effect of the technical solution of the present invention is that only the electrode part is redesigned, the original flat electrode is changed to a box-type expanded metal mesh plate electrode, the electrode distance between electrodes can be adjusted, and the electrode electrode distance can be reduced at the same time. The cell voltage is reduced and the electrodes have better current distribution uniformity.

Description

technical field

[0001] The invention relates to the field of electrodes in an aluminum foil linkage energizing production equipment, in particular to an expansion electrode applied to an aluminum foil linkage energizing equipment. Background technique

[0002] The performance of electrolytic capacitor products is closely related to the quality of the oxide film generated by aluminum foil energization. At present, the energizing equipment is mainly based on linkage energization, and the energizing production equipment is also a high-energy-consumption electrolysis equipment.

[0003] The withstand voltage of electrolytic capacitors is determined by the cell voltage of the energizing tank, so when producing high withstand voltage capacitors, the voltage of the aluminum foil energizing tank can be as high as thousands of volts. The cell voltage is mainly composed of electrode oxidation, reduction potential and electrolysis. It is composed of the hydraulic pressure drop. When th...
