Modular mixer-settler device with separate stages and mechanical stirring

摘要

The mixer-settler is modular and can be employed, handled and maintained inside a shielded leakproof enclosure by means of a remote manipulator arm. …??As shown in the plan view, it consists of a number of modules (M1, M2, M3) which can be dismantled in relation to one another by virtue of leakproof connecting means (19, 20, 21). The entries and exits (17, 18) for the heavy and light phases are assembled on the front stage (40) of each module. Adjusting keys (9, 10, 11) emerge on the upper surface of each module near the front surface (40). Each of the portholes (12) preferably makes it possible to see the intermediate phase of a stage comprising a mixing chamber (1) and a settling chamber (2). The whole is supplemented by a mechanical drive unit (3) place above the module. …??Application to the treatment of radioactive liquids. …IMAGE…
