SETTLER WITH THE HOE-TYPE STIRRER Russian patent published in 2008 - IPC B01D21/28 

FIELD: oil-producing industry; chemical industry; other industries; devices for realization of the settling processes for separation of the heterogeneous mediums.

SUBSTANCE: the invention is pertaining to the equipment foe realization of the processes of settling, that is the separation of the heterogeneous systems. The settler contains the body, the stirrer with the drive gear and the unions used for inlet and outlet of the suspensions. The body is made in the form of the cylindrical tank with the plane conical bottom and the internal annular groove along the upper edge of the settler. In the cylindrical tank there is the mounted stirrer with the inclined vanes, on which there are the hoes used for continuous relocation of the settling material to the discharge hole. At that the stirrer makes from 0.015 up to 0.5 rpm. The source liquid mixture is continuously fed through the tube into the middle of the cylindrical tank, and the clarified liquid overflows into the annular groove and is withdrawn through the union. The settling is removed from the cylindrical tank by means of the diaphragm pump. The shaft stirrer is brought in rotation by the electromotor through the reduction gear. On the bottom of the cylindrical tank there is the fixed at least one vibrator, which is automatically switched on foe 1...2 seconds after each complete revolution of the stirrer. The technical result of the invention is the increased efficiency of separation of the heterogeneous systems.

EFFECT: the invention ensures the increased efficiency of separation of the heterogeneous mediums.
