AI Technical Summary
In existing technologies, the filtration of recycled aggregates requires workers to feed materials at different locations on the filter screen, increasing labor intensity and resulting in low efficiency.
Design a filter device for impurities in recycled aggregates of commercial concrete. By setting a rotatable discharge port and drive frame on the feed channel, and using a geared motor to drive the feed channel to rotate, the material falls at different positions on the screening screen. Combined with the vibration of the screening screen and the design of the conical discharge hopper, automated screening is achieved.
It improves screening efficiency, reduces the labor intensity of staff, expands the utilization space of the screening mesh, and achieves efficient automated filtration.
