Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrolytic cathode plate maintenance, and particularly relates to a device and method for removing scale from a whole groove of a cathode plate. BACKGROUND

[0002] In the ISA electrolytic refining process in the copper smelting industry, crude copper anode plates are used as anodes, permanent stainless steel cathode plates are used as cathodes, and acid electrolyte is used as a carrier. In the process of electrification, the anode plate is continuously dissolved in the electrolyte, and high-purity cathode copper is adsorbed on the stainless steel cathode plate. Other impurities are deposited in the electrolyte. When the high-purity cathode copper on the stainless steel cathode plate reaches a certain thickness, the high-purity cathode copper and the cathode plate need to be separated, so that the stainless steel cathode plate can be used continuously, and the high-purity cathode copper can be packaged and sold. Before separation, the stainless steel cathode plate with adsorbed high-purity cathode copper needs to be put into a cleaning station together to clean the entire plate surface to remove the acid electrolyte on the cathode plate. After cleaning, it enters the next process for separation operation.

[0003] However, during repeated use of the stainless steel cathode plate, impurities in the electrolyte will accumulate on the plate surface. Some of these impurities will be taken away with the copper plate during separation, but some will accumulate on the surface of the stainless steel cathode plate. The impurities accumulated on the surface of the stainless steel cathode plate will form a layer of microscopic scale on the surface of the stainless steel cathode plate over time. When the scale reaches a certain degree, it will affect the conductivity of the surface of the stainless steel cathode plate, thereby affecting the adsorption effect of the high-purity cathode copper. In particular, near the edge strip on both sides of the stainless steel cathode plate and at the bottom of the side edge, the closer to the bottom, the more serious the problem, because the microscopic impurities contained in the side edge are more, and the side edge is the junction of the high-purity cathode copper and the edge strip. During the stripping process of the high-purity cathode copper, the impurities at the junction will flow down to the bottom of the side edge of the stainless steel cathode plate with the washing water, and will be enriched at the bottom. After the washing water evaporates, these enriched impurities will adhere to the stainless steel cathode plate, affecting the conductivity of the stainless steel cathode plate at the bottom of the side edge, thereby preventing the cathode copper from being adsorbed in time at this position, and causing the stripped cathode copper to form a hole phenomenon.

[0004] The existing method is to remove the edge strips on both sides of the cathode plate that needs to be polished, and then manually polish the cathode plate. After polishing, the edge strips are replaced or reinstalled manually to complete the scale removal process of the cathode plate. This method is time-consuming and labor-intensive, and the efficiency is not high, far from meeting the requirements.

[0005] However, when the cathode copper appears a hole phenomenon, a one-time scale removal operation is often required for a large number of stainless steel cathode plates. This operation often needs to be completed within two cycles, otherwise the stainless steel cathode plates after scale removal and the stainless steel cathode plates without scale removal will be mixed during use, causing repeated scale removal in subsequent operations.

It should be noted that the present embodiment is based on the technical solution of the present application, and gives a detailed implementation and specific operation process, but the protection scope of the present application is not limited to the present embodiment.

[0037] Embodiment 1

[0038] The present embodiment provides a device for descaling whole tank of cathode plates, which can receive whole tank of stainless steel cathode plates and automatically descale each stainless steel cathode plate. This operation mode does not need manual processing, and the processing time of the whole tank can be within 5 minutes. For 56 cathode plates per tank, as long as the crane can supply, at least 300 cathode plates per hour can be processed. At the same time, the device can also remove the microscopic impurity particles adhered to the edge strip during the descaling process of the stainless steel cathode plate, solve the problem of long lace of cathode copper, and reduce the replacement frequency of the edge strip.

[0039] As shown in Figures 1-6 A device for descaling whole tank of cathode plates includes a rack 1, a descaling mechanism 3, and a transmission mechanism.

[0040] The descaling mechanism 3 includes an up-down movable part 314, an up-down driving part, a pushing movable part 321, a pushing driving part 323, a rotating transmission assembly 332, a rotating driving part 331, a polishing wheel 35, and a polishing motor 34.

[0041] The polishing motor 34 is drivingly connected to the rotating transmission assembly 332, the rotating transmission assembly 332 is drivingly connected to two polishing wheels 35 arranged side by side, and the polishing motor 34 can drive the two polishing wheels to rotate synchronously through the rotating transmission assembly 332.

[0053] In the embodiment, the rack is provided with a transmission mechanism on each side, which independently drives the descaling mechanisms on the two sides to move horizontally forward and backward.

[0054] In the embodiment, in order to improve the efficiency, two or three descaling mechanisms can be arranged at equal intervals on the same side of the rack, each descaling mechanism is connected to the transmission mechanism, and the transmission mechanism can drive the descaling mechanisms to move synchronously. In this way, 2-3 cathode plates can be descaled at the same time, which greatly speeds up the descaling efficiency.

[0055] In the embodiment, the rack is in a U shape. The U-shaped rack is convenient for supporting the stainless steel cathode plate.
