Patent number: 12090491Abstract: A separator includes a drum ejection passage control element and an intermediate ejection control element both mounted on a drum assembly. The drum ejection passage control element is moveable between a first position and a second position. In the second position a drum ejection passage is open for ejection of material from a maximum diameter of a separator volume, while in the first position the drum ejection passage control element blocks the drum ejection passage to prevent the ejection of material from the maximum diameter of the separator volume. An intermediate ejection path is formed in the separator, each extending from an intermediate ejection path inlet at an intermediate region of the separator volume to an intermediate ejection path outlet. The intermediate ejection control element is moveable to alternately open or close the intermediate ejection path for fluid communication to the separator volume.Type: GrantFiled: May 10, 2021Date of Patent: September 17, 2024Assignee: Empirical Innovations, Inc.Inventor: Nicholas A.

Patent number: 12090492Abstract: The invention relates to an air filtration bank (100) and an air filtration system (50) for removing grit or impurities from an airstream using a plurality of cyclonic air classifiers (10) arranged in 2×2 arrays in each air filtration bank (100). The system (50) comprises a plurality of interconnected, modular air filtration banks (100) arranged side-by-side and a grit collecting chute (5). In order to improve airflow efficiency and particle separation, each cyclonic air classifier (10) includes a vortex-inducing inlet duct (13), an extraction pipe (16) and a conical diffuser (15). The conical diffusers (15) of upper and lower cyclonic air classifiers are of different lengths such that their respective waste outlets are not coplanar which serves to limit waste outlet flow interference and results in less pressure drop across the air filtration bank, which in turn leads to more efficient particle removal.Type: GrantFiled: August 27, 2021Date of Patent: September 17, 2024Inventor: Darren Richard Bibby
