The number of vertical drive members 209 is the same as the number of horizontal rods 2082. The vertical drive member 209 is preferably a cylinder.

[0140] As Figure 8 shown, the liquid inlet pipe group includes a liquid inlet main pipe 202 and liquid inlet branch pipes 203.

[0141] The liquid inlet main pipe 202 has a first end and a second end that are far away from each other. The first end of the liquid inlet main pipe 202 is a closed end. The second end of the liquid inlet main pipe 202 is used to be connected to an external liquid supply device.

[0147] The vertical driving member 209 is driven to move the horizontal rod 2082 downward. The horizontal rod 2082 drives the vertical rod 2081 to move downward, and the vertical rod 2081 drives the lower movable part 215 to move downward, so that the volume of the exchange chamber is expanded, and the resin particles in the exchange chamber are loosely filled. The main liquid inlet control valve 204 is opened, and the acid solution enters the exchange chamber through the main liquid inlet pipe 202, the liquid inlet branch pipe 203, the joint pipe 2123, the liquid distribution pipe 2121 and the connecting pipe 2122. The acid solution elutes the thorium ions adsorbed by the resin particles to form an eluent. The eluent enters the permeation cavity and enters the conduction pipe 213 through the liquid guide hole 2132. The liquid in the conduction pipe 213 of the same column of exchange units moves downward and enters the main liquid discharge pipe 205 through the liquid discharge branch pipe 210. The eluent collected in the drainage main pipe 205 is transported to the inlet main pipe 202, and enters the exchange chamber again through the inlet branch pipe 203, the joint pipe 2123, the liquid distribution pipe 2121 and the connecting pipe 2122 to elute the thorium ions adsorbed by the resin particles. The elution is repeated multiple times.
