[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 special ion exchanger (or column). The resin needs to complete processes such as transformation, cleaning, ion exchange and metal loading in the ion exchanger. The traditional ion exchangers mainly include fixed - bed, moving - bed, floating - bed and other forms. Due to the disadvantages of resin channeling, wall effect, caking, etc. in the resin bed of the traditional ion exchanger, it is very difficult to reach a complete state during the processes of resin loading metal ions, cleaning, transformation and regeneration.

[0004] In order to solve the above problems, after retrieval, an ion exchange resin tower with the Chinese patent application number 201510444855.8 and the publication date of July 27, 2015, includes a tower body.

The other end of the transmission shaft is connected to a scraping plate. The fixing plate and the transmission shaft are internally connected by an electric circuit and are connected to a controller.

[0005] Another example is an ion exchange resin tower with the Chinese patent application number 201420732302.9 and the publication 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 outlet. The lower side 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 does not require disassembly. The liquid outlet and water seepage pipe consists of three layers. The outermost layer is a perforated fiberglass support pipe, the pore diameter 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 pore diameter of which is smaller than the particle size of the adsorption resin. The innermost layer is a perforated inner support plastic pipe.

[0061] 2) The middle column body 12 is provided with a middle drain port d6121 parallel to the resin inlet d5115;

[0062] 3) The lower column body 13 is provided with a resin outlet d7131, and a lower drain / water inlet d8132 is arranged at the bottom of this part of the column body 10 for discharging or entering the liquid material, regenerant, transformation agent, and cleaning water.

[0063] As Figure 12 and Figure 13 shown, among them, the upper drain / water inlet d1111 is connected with an upper water distributor connecting pipe 23. The material of the upper water distributor connecting pipe 23 is polyvinyl chloride. The upper water distributor connecting pipe 23 includes a tee 231, an upper flange 232, and a side flange 233. The upper flange 232 is connected with a d1 connecting pipe 118 and sealed by a sealing ring A119. The side flange 233 is connected with the first water passing component 20.
