How the plant works
Coral built the following plant for the extraction of carbon fiber dust generated by 4 mold tooling machines.
Suction downpipes of suitable diameter are positioned at the rear of machine tools and connected to a main manifold. Their purpose is to ensure direct suction of dust directly to the production source. The flow rate is divided over the 4 machines according to their volume. Next, the main manifold conveys the sucked dust to an AIRCOMPACT cartridge filter. Dusty air is fed into the filter below the filter cartridges through the inlet chamber connected to the hopper. The abrupt decrease in velocity causes the larger particle size dust to precipitate directly into the collection bin, while the airflow travels back up to the filter cartridges housed in the filter housing. As it travels through the cartridges from outside to inside, the polluted air deposits the finer dust and escapes purified.
The accumulation of polluting particles caused by the continuous and intense suction of dust during processing requires periodic cleaning of the filter cartridges. Aircompact is equipped with a cyclic countercurrent cleaning system that ensures the regular efficiency of the filter through a strong jet of compressed air that can dislodge particles deposited on the outside of the cartridges.
Finally, the realized dust extraction system includes a high-performance centrifugal electric fan to convey filtered and purified air to the atmosphere via an exhaust stack.
