Polishing chamber assembly

A system comprising:

• a rotary drive unit comprising:
• a motor;
• and
• a gas feed;
• an external gas supply coupled to the gas feed;
• and
• an apparatus comprising:
• an inner drum positioned on a first axis and forming an inner chamber interior to the inner drum, the inner drum comprising:
• a plurality of inner drum perforations formed in the inner drum;
• an object intake disposed tangential to the inner drum at a proximal end of the inner drum;
• and
• an object outlet disposed at a distal end of the inner drum;
• an agitator disposed within the inner drum on the first axis coaxially with the inner drum, the agitator comprising agitation means extending radially outward, a length of the agitator extending within the inner chamber from the object intake to the object outlet, the agitator coupled to the rotary drive unit at the proximal end of the inner drum such that the motor actuates the agitator to rotate within the inner drum, the external gas supply provided from the gas feed to the inner drum via a plurality of agitator perforations in the agitator;
• and
• an outer drum disposed around the inner drum and forming an annular chamber interior to the outer drum and exterior to the inner drum, the outer drum comprising a gas outlet disposed tangential to the outer drum at a distal end of the outer drum and positioned longitudinally and axially opposite of the object intake disposed tangential to the inner drum at a proximal end of the inner drum,
• wherein a cyclonic gas flow is generated within the apparatus from the object intake to the gas outlet in response to drawing gas from the apparatus through the gas outlet while the motor actuates the agitator to rotate within the inner drum, the annular chamber positioned to receive debris removed from surfaces of objects within the inner chamber in a path of the cyclonic gas flow, the debris passed through the inner drum perforations, along the outer drum, and extracted from the apparatus through the gas outlet.

An object polishing device comprising:

• a base comprising a pair of elongated rods;
• a rotary drive unit coupled to the base, the rotary drive unit comprising:
• a motor;
• and
• a gas feed;
• an external gas supply coupled to the gas feed;
• and
• a polisher coupled to the base via the elongated rods, the polisher comprising:
• an inner drum positioned on a first axis and forming an inner chamber interior to the inner drum, the inner drum comprising:
• a plurality of inner drum perforations formed in the inner drum;
• an object intake disposed tangential to the inner drum at a proximal end of the inner drum;
• and
• an object outlet disposed at a distal end of the inner drum;
• an agitator disposed within the inner drum on the first axis coaxially with the inner drum, the agitator comprising agitation means extending radially outward, a length of the agitator extending within the inner chamber from the object intake to the object outlet, the agitator coupled to the rotary drive unit at the proximal end of the inner drum such that the motor actuates the agitator to rotate within the inner drum, the external gas supply provided from the gas feed to the inner drum via a plurality of agitator perforations in the agitator;
• an outer drum disposed around the inner drum and forming an annular chamber interior to the outer drum and exterior to the inner drum, the outer drum comprising a gas outlet disposed tangential to the outer drum at a distal end of the outer drum and positioned longitudinally and axially opposite of the object intake disposed tangential to the inner drum at a proximal end of the inner drum;
• a helical element positioned on an interior surface of the inner drum within the inner chamber and configured to direct objects within the inner drum through the object outlet;
• a vacuum device coupled to the gas outlet and configured to draw gas from the apparatus through the gas outlet;
• and
• a first dust-proof seal coupled to a proximal end of the outer drum and a second dust-proof seal coupled to the distal end of the outer drum,
• wherein a cyclonic gas flow is generated within the polisher from the object intake to the gas outlet in response to the vacuum drawing gas from the polisher through the gas outlet while the motor actuates the agitator to rotate within the inner drum, the annular chamber positioned to receive debris removed from surfaces of objects within the inner chamber in a path of the cyclonic gas flow, the debris passed through the inner drum perforations, along the outer drum, and extracted from the polisher through the gas outlet.
