From the above sections, the base assembly 2, the cathode assembly 3, and the inner container assembly 4 and the detailed description of the anode assembly 5 and other components referring to Fig. 3 again, it can be seen that in terms of the circulation relationship between the embodiment of the present invention and the drain pipe of the electrolysis device and the remaining electrolyte (not shown), the The liquid inlet pipe 23 of the base assembly 2 is used to connect the drain pipe of the electrolytic device, so that the remaining electrolyte of the electrolytic device passes through the liquid inlet pipe 23 and the flow guide 41 of the inner container assembly 4 The liquid inlet 410 is introduced into the liquid inlet section 801 of the liquid discharge space 80, passes upward through the liquid outlet hole 530 of the stopper 53 of the anode assembly 5, and then enters the liquid outlet section 802 of the liquid discharge space 80. The liquid outlet pipe 24 flowing downward into the liquid discharge channel 803 and into the base assembly 2 is discharged out of the metal ion recovery device of this embodiment.

Further in terms of the power supply relationship of the embodiment of the present invention when recovering the metal ions of the remaining electrolyte, one aspect is to use the electrically insulated base assembly 2 and the inner container assembly 4 to interact with the cathode assembly 3 and the anode assembly. 5 to form an electrical isolation to avoid a short circuit when the connecting member 33 of the cathode assembly 3 and the connecting member 54 of the anode assembly 5 are electrically connected to an external power supply (not shown). On the other hand, as shown in FIG. 3, it can be seen that the conductive sleeve 32 of the cathode assembly 3 is adjacent to the base 21 of the base assembly 2, and the position where the conductive rod 51 of the anode assembly 5 is used to connect its connecting member 54 is also adjacent The base 21 of the base assembly 2; therefore, the external power supply is powered by the base 21 to the cathode assembly 3 and the anode assembly 5. Although the cathode assembly 3 is similar to the existing metal ion recovery device, it also supplies power from bottom to top. However, according to the connection relationship between the detailed elements of the anode assembly 5, the conductive rod 51 and the anode tube 52 of the anode assembly 5 are connected to the stopper 53 at the end far away from the frame 22; therefore, when the external When the power supply supplies power to the anode assembly 5 from the base 21, the current supply path is from the conductive rod 51 to its stopper 53 from bottom to top, and then to the anode tube 52 in the transverse direction and the current downward. . In other words, with regard to the power supply relationship when recovering the metal ions of the remaining electrolyte in this embodiment of the present invention, the cathode tube 31 of the cathode assembly 3 transmits current from bottom to top, while the anode tube 52 of the anode assembly 5 is The current is transferred from top to bottom; therefore, the current transfer direction of the cathode tube 31 and the anode tube 52 can be reversed in this embodiment of the present invention to solve the existing problem of uneven current supply.

Based on the fact that the power supply path of the anode assembly 5 is longer than that of the cathode assembly 3, the anode tube 52 can supply current while the cathode tube 31 of the cathode assembly 3 faces upwards when supplying current, and the conductive rod 51 is avoided. When this embodiment performs the ion recovery process for a long time, it is oxidized by the steam formed from the remaining electrolyte to adversely affect its electrical conductivity. Therefore, preferably, the conductive rod 51 of the anode assembly 5 has a metal rod 511, and a metal rod 511 coated on the metal rod 511 to prevent the metal rod 511 from being oxidized by the vapor formed by the remaining electrolyte.

It is worth mentioning here that the cathode tube 31 of this embodiment of the present invention is wound from a titanium sheet, and an overlap of about 10 mm is reserved during the winding process to form a tubular shape. Specifically, the cathode tube 31 surrounds the outer ring wall 223 of the frame 22 of the base assembly 2, and the bottom end of the cathode tube 31 is fixed on the base 21 by the conductive sleeve 32 surrounding it, and the cathode The end (ie, the top end) of the tube 31 away from the base member 2 is filled by the upper cover 6 to close the cathode tube 31.
