The subject innovation relates to a noble metal ion exchange resin flow recovery period, the subject innovation is an ion exchange resin capable of adsorbing the noble metal in the inside is filled, phase, and it entered into the respective top cap and a bottom cap to the bottom, passing through the lower cap the first supply pipe and the second supply pipe is a waste solution of the noble metal-containing flows, and a cylindrical inner side is formed in the through one side of the bottom surface is to the inside is fixed on the bottom side is fed the waste liquid flowing from the first supply line the other end plane has a plurality of apertures which collision plate is formed and connected to the second supply line as a waste fluid supply line and, a circular shape of the interior through a plurality of injection orifices open is in a lower side of the impingement plate laterally formed and through to the outside on the outer circumferential surface and an auxiliary supply tube is formed containing a noble metal waste liquid to be supplied in multiple directions, one end to the first strainer (strainer) is attached is located on the upper side of said impingement plate vertically bent, and at the side of said impingement plate and the other side of the lower cap penetrating through precious metal recovery consisting of a discharge pipe that is the waste liquid is discharged, the noble metal is supplied air to the side of the central portion of the first strainer by passing through the upper side of the recovery tube is equipped with a third check valve air pipe and, the noble metal by introducing the contained liquid waste solution from the stock solution tank and a circulation pump for circulating back to the raw liquid tank via the noble metal recovery tube, and the pipe member for connecting the noble metal recovery reservoir and the raw liquid tank, with each successively to the first supply line the first valve and the first check valve is formed, and a second valve and a second check valve respectively, sequentially formed on the second feed pipe, a cylindrical shape is formed in the supply pipe between the circulation pump and the first and second feed tube and a second strainer is configured attached non-return passage, the circulation pump for the installed between the stock solution tank and the circulation pump is set into operation and time by automatically stopping the timer inside.
Therefore, according to the configuration of the subject innovation as described above, the recovery of precious metals to the increase in surface area which may be adsorbed to the noble metal ion can significantly increase the resin and has the advantage of shortening the precious metal recovery time.
In addition, the configuration is simple and can be miniaturized and enemies were broken and have the advantage of easy installation and maintenance, expensive parts are not needed is very useful in making this possible to devise economical at low cost.
