LABORATORY FLOTATION MACHINE Russian patent published in 2017 - IPC B03D1/14 

FIELD: machine engineering.

SUBSTANCE: machine contains a housing, a removable chamber with a lift drive, a movable platform, an aeration unit consisting of an impeller, an impeller shaft and a stator, an impeller shaft drive servo motor, a reducer, a servo motor control unit. The machine further comprises a programmable logic controller, an operator touch panel, a wireless network router, a compressed air microcompressor, a compressed air flow sensor to the aeration unit, a control valve for the compressed air flow to the aerator unit, at least two micropumps for dispensing flotation agents, a pulp level control device in the flotation machine, including a displacement cone with a drive mechanism, a casing, a pulp level sensor, and an air supply nozzle for supplying compressed air to the pulp level sensor blow. The outputs of the compressed air flow rate and pulp level sensors are connected to the corresponding inputs of the programmable logic controller. The outputs of programmable logic controller are associated with the information input of operator touch panel and the control inputs of the impeller shaft drive servomotor control unit, the compressed air microcompressor, the flotation agent metering micropumps, the control valve for compressed air flow to aeration unit, the drive mechanism of displacement cone, and the lifting drive of removable chamber. The input of wireless router is connected to the interface outputs of programmable controller and operator touch panel. The removable chamber is made in the form of a vessel in the form of a straight octagonal prism containing at least two sleeves for drainage of foam and a pocket for placing a pulp level sensor in a flotation machine. The removable chamber is made either in the form of a cylinder, or in the form of a truncated cone, or in the form of a rectangular parallelepiped.

EFFECT: improving the quality of experiments, increasing the degree of automation of the machine.
