Embodiment 1

[0043] Such as figure 1 , figure 2 As shown, a cathode stripping device is used to strip the metal layer 71 from the cathode plate, comprising:

[0044] A bracket 5 made by welding square tubes, the middle of the bracket 5 is provided with a space for accommodating the cathode 7;

[0045]Two sets of cathode support assemblies 1 are arranged symmetrically at both ends of the top of the cathode plate for supporting and fixing the cathode plate. Such as image 3 As shown, the cathode support assembly 1 includes a support frame 11 fixed on the bracket 5. The support frame 11 is a rectangular parallelepiped with an upward opening. The side plate of the support frame 11 close to the cathode 7 is provided with a V-shaped limiting groove 111 with an upward opening. The bottom of the support frame 11 is also provided with a V-shaped side limit groove 12 with an opening facing the side of the cathode plate. The side limit groove 12 is driven by a bottom limit cylinder 121, and the t...

Embodiment 2

[0051] A cathodic stripping method, comprising the steps of:

[0052] a. The cathode is transported to the stripping device by the mechanical arm. The two ends of the conductive rod on the top of the cathode plate are placed in the limit groove, and the bottom limit cylinder pushes the side limit groove to fit the side of the cathode plate, so that the cathode is centered and fixed. The limit cylinder pushes the limit plate to slide above the two ends of the conductive rod to prevent the cathode plate from rebounding;

[0053] b. The left limit oil cylinder drives the limit piece to gradually approach the cathode and touches the bottom of the cathode, the right separation cylinder drives the separation piece to gradually approach the cathode plate and pushes the middle of the cathode plate to bend to the left, and the cathode plate and the top of the left metal layer Separation, after the separation part returns to its original position, the peeling cylinder drives the chisel ...

Abstract

The invention discloses a cathodic disbonding device and method. The cathodic disbonding device comprises a support, cathode supporting assemblies, separation assemblies, lower limiting assemblies and disbonding assemblies; the cathode supporting assemblies are arranged at the top of a cathode plate and are used for supporting and fixing the cathode plate; the separation assemblies are movably arranged on the two sides of the cathode plate and used for driving the cathode plate to be bent, so that the cathode plate is separated from a metal layer on the plate; the lower limiting assemblies are arranged on the two sides of the bottom of the cathode plate, and when the separation assemblies act on the cathode plate, the lower limiting assemblies are in abutting connection to the bottom of the cathode plate to limit the cathode plate; and the disbonding assemblies comprise chisels rotationally arranged above the cathode plate, the chisels are used for being inserted between the cathode plate and the metal layer and disbonding the metal layer from the cathode plate, and chisel rotating shafts are parallel to the width direction of the cathode plate. The device is simple in structure and low in failure rate; the operation complexity is reduced; the metal layer is not prone to remaining on the cathode plate; the surface quality of the cathode plate is prevented from being reduced; and the efficiency and the metal surface quality are ensured.

Description

technical field [0001] The invention relates to the technical field of hydrometallurgical equipment, in particular to a cathode stripping device and method. Background technique [0002] The permanent cathodic electrolysis method is one of the important methods for electrolytically purifying metals. Using the principle of oxidation-reduction reaction, the metal ions in the electrolyte are positively charged and flow to the stainless steel plate as the cathode, enriched on the surface of the cathode plate, reduced to metal, and attached On both sides of the cathode plate, the purity of the cathode metal is higher. After the attachment is completed, a stripping device is usually required to strip the metal layer from the cathode plate, and then the subsequent detection and packaging processes are performed. Due to the high adhesion between the metal layer and the cathode plate, existing stripping devices are prone to problems such as incomplete stripping or residues on the ca...
