Abstract
Abstract An industrial dust collection system for collecting dust created by operation of a machine comprising dust collecting and storage means remote from the machine; a cyclone chamber means associated with the dust collecting and storage means for receiving dust laden air from the machine; forced air blower fan means associated with the cyclone chamber means for establishing a continuous induced flow of dust laden air from the machine to the fan means and for establishing a flow of dust laden air from the fan means to the cyclone chamber means; flow direction control means in the chamber means for establishing a circular and axially downward flow of dust laden air within the cyclone chamber means; vortex chamber means within the cyclone chamber means for establishing an upward flow of air in the center of said cyclone chamber means; and dust discharge passage means connecting said cyclone chamber means to said dust collecting means for transfer of dust from said cyclone chamber means to said dust collecting means prior to entry of air into said vortex chamber means.

Claim 1
Independent Claim
331 words
An industrial dust collection system for collecting dust created by operation of a machine comprising: dust collecting and storage means having a cylindrical side wall portion mounted in a vertical position for collecting and storing dust generated by a machine; cyclone chamber means mounted on the upper end of the dust collecting and storage means in a vertical position and having a cylindrical side wall portion and an annular upper end wall portion and an annular lower end wall portion and a dust inlet opening at the upper end thereof, for receiving dust laden air from the machine; forced air fan means connected to the cyclone chamber means for establishing a continuous induced flow of dust laden air from the machine to the fan means and for establishing a flow of dust laden air from the fan means to the cyclone chamber means; flow direction control means connected to said forced air fan means and being mounted in the chamber means for establishing a circular and axially downward flow of dust laden air within the cyclone chamber means; vortex chamber means mounted within the cyclone chamber means and having a vertically extending funnel shape passage located centrally and coaxially relative to said cylindrical side wall portion and an annular inlet opening of minimum diameter at the lower end of said cyclone chamber means and an annular outlet opening of maximum diameter at the upper end of said cyclone chamber means for establishing an upward flow of air therethrough in said cyclone chamber means; and said annular lower end wall portion defining dust discharge passage means in having an annular opening of a diameter greater than the diameter of said annular inlet opening of said vortex chamber means and being axially spaced therebelow for connecting said cyclone chamber means to said dust collecting and storage means for transfer of dust from said cyclone chamber means to said dust collecting and storage means prior to entry of air into said vortex chamber means.
