Minitype closed loop continuous floatation machine

The utility model provides a minitype closed loop continuous floatation machine and relates to a floatation machine for mineral separation experiments. A small number of representative ore samples are used for the continuous floatation experiments, experiment results can represent the results of single-machine minitype closed loop experiments and pilot-scale tests in laboratories, and mineral separation indexes used for the laboratories or the industry can be provided in a short time. The minitype closed loop continuous floatation machine mainly comprises a pulp storage tank, a stirring tank, a microscale reagent feeder, a rubber pipe pump and a flotation machine body. The floatation machine body comprises main motors, floatation tanks, air suction adjusting valves, scraper plate motors, scraper plates, foam tanks, liquid face adjusting pipes, a frequency changer, an electric control box, stirring shafts and impellers, the pulp storage tank is connected with the stirring tank, the stirring tank is connected with the microscale reagent feeder, the rubber pipe pump is connected with the floatation tanks, the frequency changer is connected with the main motors, the floatation adjusting pipes are installed on the floatation tanks, and the reagent feeder is connected with the stirring tank and used for supplying auxiliary suction agents, foaming agents and regulators for floatation. The minitype closed loop continuous floatation machine is mainly used for the mineral separation laboratories.
