Gas-liquid rotary separator and separation filter element for a gas-liquid rotary separator

摘要

Gas-liquid rotary separator (402) separating a liquid from a gas-liquid mixture (404), wherein the gas-liquid rotary separator (402) comprises:a separation filter assembly (406) comprising:a housing (408) with an inlet (412) to absorb the gas-liquid mixture (404), a gas outlet (414) to discharge the separated gas; anda drain outlet (418) discharging separated liquid;an annular rotary separation filter element (422) in the housing (408),a rotary drive member (424),a first set of one or more latching surfaces (426) on the rotary drive member (424),a second set of one or more latching surfaces (430) on the annular rotary separation filter element (422), wherein the second set of one or more latching surfaces (430) interacts with the first set of one or more latching surfaces (426) in blocking paired toothed relation, to cause rotation of the annular rotary separation filter element (422) by the rotary drive member (424),wherein the annular rotary separation filter element (422) rotates around an axis (434) and extends axially along the axis between the first and second axial ends (436, 438) with a respective first and second axial end cap (440, 432), wherein the annular rotary separation filter element (422) has an axially extending hollow interior (562), and comprising a third set of one or more latching surfaces (570) on the rotary drive member (424) and one wherein the rotary drive member (424) a fourth set of one or more latching surfaces (572) on the first axial end cap (440),comprises rotary drive shaft (564) extending axially through the second axial end cap (432) and axially through the hollow interior (562) and engaging the first axial end cap (440), wherein the second set of one or more latching surfaces (430) is located on the second end cap (432), wherein the first and third sets consist of one or more latching surfaces (426, 570) on the rotary drive shaft (564)located at axially spaced locations along it, wherein the first and second sets of one or more latching surfaces (426, 430) engage each other in a blocking paired toothed relationship, while the rotary drive shaft (564) extends through the second end cap (432), wherein the third and fourth sets of one or more latching surfaces (570, 572) engage each other in a blocking paired toothed relation when the rotary drive shaft (564) engages the first end cap (440).
