Abrasive and dust separator

A centrifuge media separator for separating blast particulate from fine particulate carried by air flowing from a blast cabinet through the media separator, the centrifuge media separator comprising:

• an upper panel having a central opening formed therein;
• a lower panel;
• a curvilinear outer wall extending between the upper and lower panels and having at least one particulate escape aperture formed therein;
• and
• an air foil mounted on the outer wall adjacent to the escape aperture and extending generally radially inwardly toward the central opening, the air foil being configured to facilitate exhaustion of the blast particulate through the escape aperture;
• wherein the upper panel, lower panel and outer wall collectively define a curvilinear air passageway having an inlet and an outlet, the inlet being configured for allowing a flow of air to enter the air passageway and circulate therethrough toward the outlet, the escape aperture being configured to exhaust the blast particulate out of the passageway, the central opening being configured to exhaust the fine particulate out of the passageway.

A centrifuge media separator for separating blast particulate from fine particulate carried by air flowing from a blast cabinet through the media separator, the centrifuge media separator comprising:

• a substantially planar upper panel having a circularly shaped opening formed in a central portion thereof;
• a substantially planar lower panel;
• a curvilinear outer wall having a spiral configuration of generally decreasing radius, the outer wall extending between the upper and lower panels and having at least one particulate escape aperture formed therein;
• an air foil mounted on the outer wall adjacent to the escape aperture and extending generally radially inwardly toward the central opening, the air foil being configured to facilitate exhaustion of the blast particulate through the escape aperture;
• an extension extending between the upper and lower panels and extending from the outer wall such that the outlet is located downstream of the inlet along a direction of the flow for preventing a flow reversal at the inlet;
• and
• a cylindrically shaped inner ring disposed radially inwardly relative to the outer wall and being sized complementary to and extending partially downwardly from the central opening;
• wherein the upper panel, lower panel and outer wall collectively define a curvilinear air passageway having a rectangularly shaped inlet and a rectangularly shaped outlet, the inlet being configured for allowing a flow of air to enter the air passageway and circulate therethrough toward the outlet, the air passageway being configured such that a cross sectional area thereof generally decreases along a direction of the flow from the inlet to the outlet, the outlet being disposed radially inwardly relative to and positioned downstream of the inlet such that the flow of air enters the inlet, circulates through the air passageway, exits the outlet, and rejoins the flow of air entering the inlet, the escape aperture being configured to exhaust the blast particulate out of the passageway, the central opening being configured to exhaust the fine particulate out of the passageway.

A blast cabinet having a centrifuge media separator for separating blast particulate from fine particulate carried by air flowing from the blast cabinet and into the media separator, the blast cabinet having a housing defining an enclosure and being configured for blasting a workpiece disposed within the enclosure, the centrifuge media separator being mounted on the housing and comprising:

• an upper panel having a central opening formed therein;
• a lower panel;
• and
• a curvilinear outer wall extending between the upper and lower panels and having at least one particulate escape aperture formed therein;
• wherein the upper panel, lower panel and outer wall collectively define a curvilinear air passageway having an inlet and an outlet, the air passageway being configured such that a cross sectional area thereof generally decreases along a direction of the flow from the inlet to the outlet, the inlet being configured for allowing a flow of air to enter the air passageway and circulate therethrough toward the outlet, the escape aperture being configured to exhaust the blast particulate out of the passageway, the central opening being configured to exhaust the fine particulate out of the passageway.
