Abstract
A stirring apparatus (1), with a stirring tool and a measurement apparatus (2) for the measurement of torque that is introduced during stirring into the medium that is to be stirred, is mounted on bearings on its holding device (4) in such a way that it can rotate or pivot around the axis of rotation of the stirring tool, and is supported against the direction of rotation of the stirring tool. The measurement of the torque is carried out by means of a measurement value sensor, which records the reaction force of this support directly or indirectly. A measurement value sensor that is fixed in position can be used for the measurement of the torque, and the measurement of the torque requires only a single pivot bearing (11).
Claims21
A stirring apparatus (1) adapted for measurement of torque that is introduced into a medium that is to be stirred comprising a holding device (4) and a stirring mechanism (3) having a stirring mechanism drive and a stirring tool, means for mounting the stirring mechanism to the holding device (4) such that the stirring mechanism drive can rotate around an axis of rotation of the stirring tool, means for supporting the stirring mechanism drive against a direction of rotation of the stirring tool to limit the rotation of the stirring mechanism drive, and a measurement apparatus (2) for recording a reaction force of the supporting means as it limits the rotation of the stirring mechanism drive, the holding device (4) comprising a plug and socket connection adapted to removably receive the stirring mechanism drive (3).
A holding device (4) for measurement of torque that is introduced into a medium that is to be stirred by a stirring mechanism (3) having a stirring mechanism drive and a stirring tool, the holding device (4) comprising:
- mounting means adapted for mounting the stirring mechanism drive to the holding device (4) such that the stirring mechanism drive can rotate around an axis of rotation of the stirring tool;
- anti-torque means adapted for supporting the stirring mechanism drive against a direction of rotation of the stirring tool to limit the rotation of the stirring mechanism drive;
- a measurement apparatus (2) for recording a reaction force of the anti-torque means as it limits the rotation of the stirring mechanism drive;
- and
- a plug and socket connection, adapted to removably receive the stirring mechanism drive, into which the stirring mechanism (3) can be inserted.
