CN202131378U - Stainless steel insoluble negative plate used for producing electrolytic nickel - Google Patents

Abstract

A stainless steel insoluble negative plate used for producing electrolytic nickel is formed by welding a beam and a pole plate, wherein crisscross grooves are arranged on the two surfaces of the pole plate; acidproof nonmetal U-shaped strips are buckled and pressed at the two side edges of the pole plate; a reversed V-shaped groove is arranged at the bottom of the pole plate; the beam is formed through the combined extrusion of T1 and 316L stainless steel; and the pole plate is made of the 316 stainless steel. The negative plate greatly shortens the production procedures of the electrolytic nickel, reduces the technological process, and lowers the cost; and the pole plate itself has certain weight and is greatly increased in weight after being subject to electrolytic absorption, and therefore the pole plate has enough strength.

Description

A stainless steel insoluble cathode plate for producing electrolytic nickel

technical field

The utility model relates to a stainless steel insoluble cathode plate for producing electrolytic nickel.

Background technique

In the process of nickel refining, the preparation of electrolytic nickel generally uses titanium plates to prepare seed plates. The main point of this method is to insert the titanium plate into the seed plate electrolytic cell used for the preparation of the seed plate, in the nickel electrolytic solution of a certain concentration and temperature, pass a current of a certain voltage and current intensity for electrolysis, and adsorb on the titanium plate After a certain thickness of metal nickel, the metal nickel is peeled off, and the stripped metal nickel plate is used as an electrolytic cathode plate and inserted into the electrolytic cell solution for production. After the seed plate absorbs metal nickel to a certain thickness, an electrolytic nickel plate is generated. The electrolytic plate is used as The final product of the nickel electrolysis process. Due to the process of preparing the seed board, the increase of the process greatly improves the cost and the manufacturing process.

Contents of the invention

The purpose of the utility model is to provide a stainless steel insoluble cathode plate for producing electrolytic nickel in order to overcome the problems existing in the prior art.

The utility model relates to a stainless steel insoluble cathode plate for producing electrolytic nickel. Metal "U"-shaped strips, with inverted "V"-shaped grooves at the bottom of the plate.

The beam is made of compound extrusion of T1 and 316L, and the pole plate is 316L stainless steel plate.

Compared with the prior art, the utility model has the following advantages:

1. The utility model greatly shortens the production process of electrolytic nickel, reduces the process flow and reduces the cost.

2. The polar plate itself of the utility model has a certain weight, and the weight increases greatly after electrolytic adsorption, so the polar plate has sufficient strength and good flatness.

3. The beam of the utility model has good electrical conductivity and corrosion resistance, and has sufficient rigidity.

In the figure: 1-beam 2-polar plate 3-well shaped groove 4-inverted "V" shaped groove 5-"U" shaped bar

Detailed ways

As shown in Figure 1 and Figure 2, a stainless steel insoluble cathode plate for the production of electrolytic nickel is welded by a beam 1 and a pole plate 2, and the two sides of the pole plate 2 are provided with well-shaped grooves 3 to improve the pole plate surface adhesion; the two sides of the pole plate 2 buckle the acid-resistant non-metallic "U"-shaped strip 5 to prevent the electrolytic nickel plates on both sides from sticking together; the bottom of the pole plate 2 is provided with an inverted "V"-shaped groove 4, which is Form charge concentration to prevent the electrolytic nickel plates on both sides from sticking together; as shown in Figure 3, the beam 1 is made of T1 and 316L composite extrusion, and the pole plate 2 is a 316L stainless steel plate.

When in use, the utility model is directly inserted into the electrolytic cell for producing nickel, and after the metallic nickel adsorbed on the surface of the pole plate 2 reaches a certain thickness, the insoluble cathode plate is taken out as a whole, and the metallic nickel grown on the two adsorption surfaces is peeled off, and each time it can produce Two electrolytic nickel plates, the insoluble cathode plate after stripping the metal nickel is reinserted into the electrolytic cell to enter the production process, which can be used repeatedly. The stripped electrolytic nickel plate is the final product of the nickel electrolysis process.
