Belt separator system with improved tensioning mechanism
The granted patent US12012287B2 introduces a novel tensioning mechanism designed to maintain tension in an endless belt, which is integral to a belt separator system. The mechanism features a tension roller that applies tension to the belt, supported by a pair of rotating disks at each end of the roller. These disks are connected to a rotating shaft assembly, which consists of an inner shaft driven by an actuator and an outer shaft that accommodates the inner shaft. This configuration ensures that both disks experience similar angular deflection, allowing for balanced torque application. The tensioning mechanism is part of a broader belt separator system that includes two sets of rollers and electrodes that create an electric field for particle separation.
Additionally, the patent outlines various features of the tensioning mechanism and the belt separator system. The rotating disks are designed to remain coaxial with the rotating shaft assembly, and they can also function as part of an enclosure to enhance safety during operation. The system allows for differential motor torque application on the drive rollers, optimizing the tension based on the contact length with the belt. The method of separating a particle mixture involves introducing the mixture into the system, applying a separation influence, and mechanically moving the components for effective separation. The design emphasizes safety and efficiency, particularly in scenarios that may generate axial forces, ensuring the integrity of the rotating components during operation.
