[0048] The implementation principle of a palladium ion recovery device in an embodiment of the present application is as follows: the filtering device 1 first removes solid particles in the palladium ion-containing liquid, and the resin exchange device 2 adsorbs palladium ions on the liquid filtered by the filtering device 1. When the resin needs to be replaced, the motor 24 rotates, the gear 241 rotates to make the rack 242 slide, so that the storage basket 22 slides in the opening 211 and away from the exchange box 21, and the resin passes through the opening 221 and falls into the recovery tank 23, pushing the lowest sliding plate 224 to block the opening 221 of the lowest storage basket 22, the auger 42 transports the resin, and the stirring rod 46 preliminarily stirs the resin so that the resin falls evenly into the storage basket 22. When the resin falls into the storage basket 22, the resin contacts the screen 472 and generates an impact force on the screen 472, and the screen 472 slides vertically in the opening 3 477, and the screen 472 drives the sliding block 2 to slide in the sliding groove 478, and the sliding block 2 squeezes the spring 475. When the impact force disappears, the spring 475 resets to move the screen 472 upward, and the reciprocating movement of the screen 472 makes the resin evenly distributed in the storage basket 22, and the slider 476 drives the material leveling plate 471 to rise, and evenly distributes the resin above, thereby improving the uniformity of the resin in the storage basket 22. When the storage basket 22 is full of resin, the connecting shaft 254 drives the sliding plate 224 to move through the connecting rod 255 to seal the opening 221 of the storage basket 22, and the rack 242 drives the storage basket 22 to enter the exchange box 21, and multiple activated carbon adsorption plates 33 further adsorb the palladium ion-containing waste liquid. The resin replacement process of the resin exchange device 2 reduces manual operation, which is beneficial to reducing the manpower and time of the replacement process and improving the convenience of resin replacement.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
