A dispersive feeding type copper melting tank applied to the preparation of electrolytic copper foil

Abstract

The invention discloses a dispersive feeding type copper-dissolving tank for the preparation of electrolytic copper foil, which comprises a tank body, a cover body is installed on the top of the tank body, and a feeding bin is installed at the center of the surface of the cover body, and the feeding bin is composed of concentric The set outer retaining ring, the inner retaining ring and the cover are enclosed, and the surface of the cover is located between the outer retaining ring and the inner retaining ring and has a plurality of first feeding ports. In the present invention, all the copper powder is directly added into the feeding bin, and by setting a dispersed feeding component on the top of the copper melting tank, the copper powder in the feeding bin can be continuously and automatically added in batches during the reaction process to ensure that The copper powder added each time can react quickly under the agitation of the multi-directional dispersive stirring mechanism, and the reaction is complete before sinking to the bottom of the tank, which will not cause the accumulation of copper powder, and through the feed limit adjustment part and the bottom The cooperation between the blocking components can carry out automatic feeding without manual feeding.

Description

technical field [0001] The invention belongs to the field of preparation of electrolytic copper foil, and relates to a dispersion-feeding type copper melting tank applied to the preparation of electrolytic copper foil. Background technique [0002] In the preparation process of electrolytic copper foil, it is necessary to add copper material to the acid solution to prepare copper ion solution. Usually, the copper coil is directly added to the copper melting tank, which makes the accumulation at the bottom difficult to disperse evenly, which in turn makes a large amount of copper at the bottom of the copper melting tank. Material accumulation can not react, resulting in waste of raw materials. In order to improve the reaction efficiency of copper material and acid solution, copper powder is usually used as copper material in the prior art and directly added to the copper-dissolving tank for reaction before the reaction. Although it can improve the copper The contact area betw...

[0002] In the preparation process of electrolytic copper foil, it is necessary to add copper material to the acid solution to prepare copper ion solution. Usually, the copper coil is directly added to the copper melting tank, which makes the accumulation at the bottom difficult to disperse evenly, which in turn makes a large amount of copper at the bottom of the copper melting tank. Material accumulation can not react, resulting in waste of raw materials. In order to improve the reaction efficiency of copper material and acid solution, copper powder is usually used as copper material in the prior art and directly added to the copper-dissolving tank for reaction before the reaction. Although it can improve the copper The contact area between the material and the acid solution accelerates the reaction of the copper material, but the copper powder is also easy to accumulate at the bottom of the copper melting tank after the copper powder is directly added, thereby affecting the complete reaction of the copper material
