STIRRING DEVICE Russian patent published in 2006 - IPC B01F9/00 B01F15/00 

FIELD: food industry; pharmaceutical industry, chemical industry; paint-and-lacquer industry; other branches of industry; production of devices for stirring.

SUBSTANCE: the invention is pertaining to devices for stirring intended for preparation of solutions, for example, emulsions, suspensions and may be used in food industry, pharmaceutical industry, chemical industry, paint-and-lacquer industry and other industries. The stirring device contains the frame, on which there is the post with the turning platform and the tank with the central internal stirring tool. The turning platform is mounted on the post with the possibility of motion in the vertical direction and fixation of its position. On the turning platform there is the drive with the asynchronous electric engine and the frequency converter, which is electrically connected with the latter. The arbor of the stirring device is passing through the central hole in the cover of the tank body and through the quick-detaching coupling is connected to the driving arbor. The cover is supplied with the obturator mounted in its central hole and interacting with the stirrer arbor. The tank body is installed on the supports disposed on the indicated frame enabling the tank turning around of the vertical shaft. The tank is made detachable. The device is supplied with the tool to fix the tank in the vertical position. In the wall of the tank body there is a sealed transparent observation window to control over the level and the qualitative state of the mixture inside. The turning platform is installed on the cylinder, which is mounted on the post with a possibility of the longitudinal motion by the screw gear. The screw gear is made with the nut, the butt of which interacts with the meeting butt of the cylinder. The drive with the asynchronous electric engine is made in the form of the gear-motor drive. The invention ensures improvement of the operational conditions for relocation of the stirring device at maintenance, expands its operational capabilities and provides the device with the better adaptability to the stirring of the components of the mixture in the wide range of values of their viscosity and density.

EFFECT: the invention ensures improvement of the operational conditions for motion of the stirrer at maintenance, expands its operational capabilities and provides the device with the better adaptability to the stirring of the mixture components in the wide range of values of their viscosity and density.
