[0032] In use, through the mutual cooperation between the gas conveying structure and the third gas conveying pipe 16, the piston block 25 can drive the movable rod 23 to move inward synchronously, so that the pressing block 14 and the multiple connecting rods, as well as the first movable block 12 and the second movable block 13, can move relatively in the reaction channel, with the movement of the piston block 25, the first movable block 12 and the second movable block 13 can move closer or farther away from each other, thereby controlling the mixing speed and degree of the reactants, by dividing the resin in the reaction bucket 1 into two parts, the first movable block 12 and the second movable block 13, the resin particles can be more fully contacted with the fluid to be treated during the adsorption process, increasing the adsorption area and thus improving the adsorption efficiency, especially when the upper layer of resin is close to saturation, the unsaturated resin in the lower layer can replace the upper layer of resin by moving to continue effective adsorption, so that the concentrated brine can be fully contacted with the resin, and this structure is beneficial to better removal of iodine ions in the concentrated brine, and the design of layered movement helps to avoid overuse of the resin, when the upper layer of resin reaches the saturation state, the lower layer of resin can be moved to replace it, so that the upper layer of resin has the opportunity for regeneration treatment, thereby prolonging the service life of the entire resin layer.

[0033] The first gas pipe 7 is located outside the reaction barrel 1, which avoids occupying space inside the reaction barrel 1, so that the inside space of the reaction barrel 1 is more spacious, which is beneficial to the mixing and reaction of materials. The second gas pipe 15 is located at the middle position of the third gas pipe 16 and is connected with them, which makes the gas flow smoothly from the air pump 6 through the first gas pipe 7, the second gas pipe 15, and finally into the third gas pipe 16, reducing the gas flow resistance and energy loss. The air pump 6 is fixed on the top of the top cover 4, which is convenient for installation and maintenance, and can quickly provide the required gas for the system. The smooth connection of the first gas pipe 7 and the second gas pipe 15 ensures that the gas can be quickly delivered to the inside of the reaction barrel 1 or the designated position. The design of multiple sets of lock blocks 8 can ensure the tight connection between the top cover 4 and the reaction barrel 1, effectively prevent the leakage of liquid during the reaction, and ensure the stability and safety of the reaction environment. The design of the lock block 8 can prevent the top cover 4 from being accidentally opened during the reaction, improving the safety of the equipment.

[0034] The design of multiple groups of support legs 3 in this embodiment can significantly increase the overall load-bearing capacity of the reaction bucket 1, ensuring that it is not prone to tilting or collapsing during placement, operation or transportation, thereby improving the stability and safety of the device. The support legs 3 are connected to the bottom of the reaction bucket 1 through the fixing ring 2, which can evenly distribute the weight of the reaction bucket 1 and its internal materials to each support point, reducing the phenomenon of single-point stress and thereby prolonging the service life of the device. Since the third gas delivery pipe 16 is located in the cavity inside the fixed pipe 10, its flow path is more direct and short, thereby reducing the flow resistance of the gas or liquid during transportation, which helps to improve the transportation efficiency and response speed of the system. By opening a cavity inside the fixed pipe 10 and accommodating the third gas delivery pipe 16, this design significantly saves space for the device. The sealing ring 22, as a filler between two contact surfaces, can effectively prevent gas or liquid from leaking from the gap between the piston bucket 20 and the fixed pipe 10. The sealing ring 22 is usually made of elastic materials such as rubber, silicone, etc., which can adapt to different shapes and sizes of contact surfaces, providing reliable sealing. In addition, they can also compensate for small displacements caused by vibration, temperature changes, etc., to maintain the sealing effect. For specific working environments, the material of the sealing ring 22 can be selected to have corrosion resistance to ensure long-term stable operation of the system. The sealing block 24 is fixedly connected to the bottom of the piston bucket 20, which ensures that the connection between the piston bucket 20 and the connecting pipe 21 has good sealing performance. The sealing block 24 is usually made of pressure-resistant and corrosion-resistant materials, which can effectively prevent gas or liquid from leaking in high-pressure or corrosive environments, thereby ensuring the stable operation of the entire device. The connecting pipe 21 is fixed in the middle of the sealing block 24, which not only simplifies the installation process but also enhances the stability of the overall structure. It reduces the risk of system performance degradation caused by the displacement or loosening of the connecting pipe 21, ensuring that the stability of the entire device is not affected when the movable rod 23 moves through the top of the piston bucket 20.
