The optimal state of resin is a compact bed, and corresponding equipment comprises two main types of fixed bed and compact moving bed devices. The common domestic equipment is a fixed bed, and in order to prevent resin leakage, the common filtering method is generally to manually fill a quartz sand filtering layer or a PVC pipe and filtering net combination body at the bottom in the uranium hydrometallurgy ion exchange tower, so that the liquid outlet problem is usually solved, and the problem of resin leakage in the back flushing operation is not solved. The main disadvantages of these two methods are: (1) the resin is directly contacted with the quartz sand layer in a large area, so that the resin abrasion is increased; (2) during the back washing process, the filter screen at the upper part of the tower body is easy to damage, and the resin leakage phenomenon is caused; (3) the replacement of the filter layer requires a long time and a large amount of labor; (4) the filter screen is easy to be damaged in the using process and has short service life.
