Problems solved by technology

Since the stainless steel plate and the conductive copper strip are fixed or closely matched by bolts, during the production process, the conductive copper strip and the stainless steel plate are often exposed to electrolytes such as manganese sulfate and ammonium sulfate, which easily leads to corrosion of the stainless steel bolts.
And after the knocking and vibration of the subsequent stripping process, the stainless steel bolts between the stainless steel plate and the conductive copper strip are loosened, resulting in an increase in contact resistance. During electrolysis, the electric energy is converted into heat energy here and generates heat, which seriously affects the output and current efficiency. At the same time, it causes an increase in energy consumption. Big

Embodiment Construction

[0015] Such as Figure 1~3 As shown, a composite energy-saving cathode for electrolytic manganese, including a stainless steel plate 1, a handle, and the handle is connected to the stainless steel plate 1. The handle is formed by connecting a stainless steel bar part 2 and a composite material part 3 . The stainless steel plate 1, the stainless steel bar part 2 and the composite material part 3 are welded by stainless steel. A handle 4 is fixedly connected on the handle, and the handle 4 is a stainless steel handle welded on the handle.

[0016] The composite material part 3 is composed of stainless steel strips and copper strips through explosive welding. Divided into: upper and lower layers of copper bars, with two layers of stainless steel bars in the middle, the copper bars and stainless steel bars are bonded by explosive welding.

[0017] The ends of the stainless steel strip part 2 and the composite material part 3 are respectively provided with stepped surfaces, and ...

Abstract

A compound energy-saving cathode for electrolytic manganese includes a stainless steel plate and a handle connected with the stainless steel plate, wherein the handle is formed by connecting a stainless steel bar part and a compound material part; and the compound material part is formed by welding and compounding the stainless steel bar and a copper bar through explosion. The compound energy-saving cathode effectively saves copper materials, reduces the resistance of the cathode, effectively saves energy and reduces consumption, and improves the economical benefits.

Description

technical field [0001] The invention relates to a composite energy-saving cathode for electrolytic manganese, belonging to the field of electrolytic manganese preparation. Background technique [0002] At present, the cathode used in the electrolytic manganese production process consists of three parts: conductive copper strips, stainless steel plates and stainless steel bolts. Since the stainless steel plate and the conductive copper strip are fixed or closely matched by bolts, during the production process, the conductive copper strip and the stainless steel plate are often exposed to electrolytes such as manganese sulfate and ammonium sulfate, which easily lead to corrosion of the stainless steel bolts. And after the knocking and vibration of the subsequent stripping process, the stainless steel bolts between the stainless steel plate and the conductive copper strip are loosened, resulting in an increase in contact resistance. During electrolysis, the electric energy is c...
