Abstract
A dynamically real-time adaptive trommel screen system is revealed. The dynamically adaptive trommel screen system includes a fixture, a trommel screen disposed on the fixture for screening a mixture into regenerated filter granules and screened residues, a structured duct for transporting the regenerated filter granules and an enclosure for collecting the screened residues, a tilt control member arranged on the fixture for adjusting the tilt angle of the trommel screen, and a feedback controller that controls the tilt control member according to the mass flow rate of the screened residues when the trommel screen operates so as to adjust the tilt angle of the trommel screen instantly and dynamically. By the feedback controller and the tilt control member, the tilt angle of the trommel screen is adjusted in a real-time and dynamic way so as to increase the screening efficiency. Moreover, the state of fractured filter granules is acquired from the feedback controller so that a certain amount of fresh filter granules can be refilled into the filter system for improving the filtration efficiency.
