[0002] The IE technology is a new type of electrowinning technology. It uses metal ions loaded on resin as the metal source for metal ion electrodeposition, replacing the traditional electrowinning that uses metals, metal salts, metal oxides or hydroxides as the metal source. During the electrowinning process, the electrolyte continuously passes through the resin loaded with metal, exchanges the metal ions loaded on the resin, and supplements them into the electrolyte to maintain the metal content in the electrolyte, so that the metal electrodeposition proceeds continuously and stably.

[0003] Loading metal ions on resin needs to be carried out in a dedicated ion exchanger (or column). The resin needs to complete processes such as transformation, cleaning, ion exchange for loading metal, etc. in the ion exchanger. The traditional ion exchangers mainly include fixed beds, moving beds, floating beds, etc. Due to the drawbacks of resin channeling, wall effects, caking, etc. in the resin bed of the traditional ion exchanger, it is very difficult to achieve a complete state during the processes of resin loading metal ions, cleaning, transformation, and regeneration.

[0004] To solve the above problems, after retrieval, an ion exchange resin tower disclosed in Chinese Patent Application No. 201510444855.8 with an application date of July 27, 2015, includes a tower body. The upper part of the tower body is provided with a water inlet and a feed inlet. The side of the lower part of the tower body is provided with a discharge outlet. The bottom of the tower body is provided with a water outlet. The top of the tower body is provided with a driving device. The driving device is connected to a stirring rod. Blades are arranged on the stirring rod. A fixing plate is arranged above the inner wall of the tower body. A transmission shaft is connected to the fixing plate. The other end of the transmission shaft is connected to a scraping plate. The fixing plate and the transmission shaft are internally electrically connected and connected to a controller.

[0005] Another example is an ion exchange resin tower disclosed in Chinese Patent Application No. 201420732502.9 with an application date of November 26, 2014, which includes a tower body, a rotating shaft, a driving device for driving the rotating shaft to rotate, stirring blades, a liquid distributor, and a monitoring camera connected to an external display device. The upper part of the tower body is provided with a feed inlet, a water inlet, and an exhaust port. The side of the lower part of the tower body is provided with a discharge outlet, and the bottom is provided with a water outlet. The monitoring camera is arranged on the inner wall of the upper part of the tower body. The liquid distributor is arranged above the inside of the tower body. The driving device is arranged above the tower body. The rotating shaft is located inside the tower body and passes through the liquid distributor. The upper end of the rotating shaft is in transmission connection with the driving device, and the stirring blades are fixed on the rotating shaft.

[0006] The Chinese patent application number is 200820182831.5, and the application date is December 24, 2008. It discloses a fixed-bed ion exchange adsorption device that can be used without disassembly. The liquid outlet and water seepage pipe consists of three layers. The outermost layer is a perforated fiberglass support pipe, the aperture of which is smaller than the particle size of the sand and gravel in the filter layer. The middle layer is a double-layer stainless steel filter screen, the aperture of which is smaller than the particle size of the adsorption resin. The innermost layer is a perforated inner support plastic pipe.
