Graphite graphite cutting cartridge filter, comes out harmful gases or dust during sanding, fine dust lighter graphite machine shop, often floating in the air, if not dust control measures taken, it will seriously affect the health of workers. A source in the company based on the characteristics of graphite and graphite machining characteristics, the design scheme of graphite dust - Graphite cartridge filter. The combined effect of graphite cartridge filter works by Brownian diffusion and sieving the dust and other particles in the gas barrier in the filter surface, the purified gas is discharged from the exhaust pipe through the fan. With the increase of the thickness of the filter surface dust, dust removal device resistance is gradually increased, when the resistance reaches a certain value, PLC program control pulse valves open and close, high-speed jet of compressed air through the gas injection tube within the package, while the induction of multiple in ambient air into the gas jet cartridge, inside out by rapid injection, the outer surface of the cartridge dust blowing dust chamber fall, finally discharged from the discharge hopper. Graphite cartridge filter features a high collection efficiency, filter effects, small size, stable 2, cartridge using skeleton installation, good sealing performance, easy installation and maintenance 3, thorough cleaning, without prejudice to the cartridge long life 4, the inlet and outlet duct layout compact, small gas resistance
