Wood chip air separation system
By designing a dedicated air separation system, using flat air nozzles and an adjustable distributor, efficient screening and impurity removal of wood chips are achieved. This solves the shortcomings of existing water washing and traditional air separation systems, improves fiberboard quality and equipment lifespan, and reduces energy consumption and costs.

Abstract
A wood chip air separation system is provided, configured between the shaving and thermal refining processes on a fiberboard production line, for screening qualified wood chips from the initial shavings. The system includes a material conveyor belt, flat nozzles, a first collection channel, a second collection channel, and a third collection channel. The material conveyor belt is inclined downwards from the inlet, configured to evenly spread the material and convey it at a constant speed from the inlet to the air outlet of the flat nozzles. The flat nozzles are inclined upwards from the air source, with their air outlets located adjacent to the lower end of the material conveyor belt, and configured to allow the material to converge with the airflow along the airflow direction of the flat nozzles. The first, second, and third collection channels are respectively distributed according to the trajectory positions of materials of different densities, for collecting materials of different densities from heaviest to lightest.
