Abstract

This invention relates to ion exchangers and can be used in the hydrometallurgical, chemical, food industries. The purpose of the invention is to improve the conditions of mixing of the pulp and ion exchanger by their multiple sectional dispersion. The apparatus includes mixing chambers, settling chamber with airlift, separation devices, disperser with compressed air supply nozzles and nozzles for the solid and liquid phases. The apparatus is equipped with several additional mixing chambers interconnected in a series and having gates and hinged flaps. In this case, the last mixing chamber is connected to the settling chamber. 3 il.

The invention relates to sorption apparatus for carrying out processes in a liquid-solid system and can be used in chemical, hydrometallurgical and other sectors of the national economy.

The purpose of the invention is to improve the conditions of mixing of the pulp and ion exchanger due to their multiple sectional dispersion.

Figure 1 shows the apparatus, a general view; FIG. 2 is a section A-A in FIG. one; on fig.Z - section bb in figure 1.

The apparatus includes a housing 1 with mixing flow chambers 2 placed in it, partition walls 3 separated from each other, having a gate 4 with a variable lift amount, and swivel dampers 5, which form adjustable flows 6 to communicate the chambers with each other. In the central part of the apparatus there is a cylindrical settling chamber 7 with airlift 8. In the upper part there is a drainage 9, equipped with a resin trough 10 having a series of nozzles 11 for collecting the sorbent with valves 12 for solids extraction. The liquid and solid phases are fed and removed from the apparatus, respectively, by nozzles 13-16. In the lower part of the apparatus, an apparatus 17 is provided for supplying dispersed air to the mixing chambers 2 and to the airlift 8.

The device works as follows.

The sorbent entering the apparatus through the nozzle 13 and the pulp through the nozzle 14 are mixed with dispersed air, then the mixture is fed through an adjustable overflow 6 into the next direct mixing chamber, and from the last mixing chamber through an adjustable overflow into the settling chamber 7. From the settling chamber 7 suspension transport

The airlift 8 is fed to a drainage 9. Located in the upper part of the apparatus, where the ion exchanger separates from the pulp, is fed into the resin chute 10, where through the outlet valves 12 and the inlet pipes 11 can be distributed into the mixing chambers 2 or sent to the next technological stage through pipe 15, and the slurry is discharged through pipe 16.

Multiple circulation of the ion exchanger in the mixing chambers is ensured by the hinged flaps 5 and leads to a high degree of mixing with the pulp,
