Metal grinding dust of history into the modern industrial society, metal - metal products industry is the rapid development of the hardware industry has played an invaluable role in national economic development, hardware manufacturing industry has become an indispensable part of an industry. In metal polishing workshop will produce a lot of dust particles, which affects not only the lives and health of dust workshop environment even affected workers. To do this source in Zhengzhou for research and development to design a workshop sanding dust removal equipment - hardware polished metal sanding dust through cartridge filter dust collector is a dry dust removal equipment, metal grinding dust removal efficiency high, covering area is small, stable, cartridge using skeleton installation, good sealing performance, solid and reliable; box with airtight design leakage rate is very low, the inlet and outlet duct layout compact, air resistance; metal polishing filter cleaning using pulse-jet way, both do a thorough cleaning, without harming the cartridge so that the cartridge life can be protected. Cleaning process is automatically controlled by a pulse controller, can be used to control the pressure difference or time control. After sanding dust hardware works dusty gas from the inlet into the dust, slow air speed, coarse particles from the air stream into the dust settling chamber, fine dust with the air passes through the filter cartridge was blocked on the outer surface of the cartridge, clean gas from the exhaust outlet.
