Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
93 words
A hydrocyclone separator comprising: a truncated cone-shaped vessel having a tangential fluid stream inlet and a fluid stream outlet, wherein an inlet tube detachably connects the truncated cone-shaped vessel to a solids particle collector; and a conical insert mounted between the truncated cone-shaped vessel and the inlet tube, wherein the inlet tube is of uniform diameter and the conical insert is erosion resistant and detachably mounted at its wide end with its tip unsupported and suspended within the free space of the inlet tube without direct or indirect contact with the inlet tube.
Claim 2
Dependent Claim
93 words
A hydrocyclone separator comprising: a truncated cone-shaped vessel having a tangential fluid stream inlet and a fluid stream outlet, wherein an inlet tube detachably connects the truncated cone-shaped vessel to a solids particle collector; and a conical insert mounted between the truncated cone-shaped vessel and the inlet tube, wherein the inlet tube is of uniform diameter and the conical insert is erosion resistant and detachably mounted at its wide end with its tip unsupported and suspended within the free space of the inlet tube without direct or indirect contact with the inlet tube.
Claim 3
Dependent Claim
29 words
A hydrocyclone separator as in claim 1 , wherein the insert is mounted between two flanges, one flange on the vessel and the other flange on the inlet tube.
