Description

Technical Field

[0001] The utility model relates to the technical field of overload protection mechanisms, in particular to a novel torque limiting protection structure of a spiral sedimentation centrifuge. Background Art

[0002] In the high-speed rotating horizontal conical drum of the centrifuge, there is a screw conveyor with the same rotating direction. It relies on the differential speed of the differential to make its rotating speed lower than the rotating speed of the drum. The slurry is fed into the drum through the feed pipe in the rotating shaft. Under the action of strong centrifugal force, the solid and liquid are separated by stratification to achieve the purpose of separation. Torque overload protection, as the name suggests, is a protection for maintaining the safety of the machine and equipment when the torque load exceeds a certain limit value;

[0003] During the operation of the centrifuge, the equipment continues to run after the torque is overloaded, which seriously damages the equipment and affects its service life. When used for a long time, the equipment has stopped running when the torque does not reach the maximum acceptable torque value of the equipment, which poses a great safety hazard.
