Dust Extractor (AR-CH2-8)

Cartridge collectors are highly efficient in collection of dust with high bulk densities and fine dust particles. Filter cake forms well at low pressure drop and has high filtration efficiency. In a study conducted by the American Foundry Society it was found that the outlet dust flow in cartridge collectors was the least in comparison with other dust collectors in foundry operationsDust Collection ConsiderationsFine dust normally adheres to surface of filter element and accumulates other fine dust particles as well When accumulated dust cake formed properly and is large enough and unaffected by upward air streams, it falls into the hopperBy increasing space between cartridges, the problem of dust falling on adjacent cartridges is reduced. It must be remembered that the system efficiencies of cartridge collectors depend upon good cleaning of the cartridge and not by adding more filter media in the cartridge. Additional filter media neither improve function nor life of the cartridge. By merely adding filter media it is likely that even the initial advantages in terms of airflow and pressure drop may be lost. The amount of filter media should be decided based on nature and size of dust particle. Proper Seal DesignSeals are useful for separating dusty air from cleaned filter air. They are also used to maintain differential working pressures (separating atmospheric pressure from system pressure). If the seal design is flawed, cartridges could quickly get plugged and system loses efficiency. The use of a compression spring mitigates seal deflection problems. Seal design must take into account an appropriate size of seal as well as material strength such that it is robust and does not get crushed. The cartridge opening is sealed by an inner door cover, an outer door plate that separates the dust chamber from the atmospheric pressure and washers that seal outside door handle from internal dirty air chamber. The door parts are attached to one another and installation or dismantling
