Abstract
Abstract A hydrocyclone separator has a tangential inlet comprising an inlet nozzle that accepts a mixture to be separated and a diluting liquid. The inlet is at one end of the hydrocyclone and a heavy fraction outlet is at the other end. The inlet nozzle introduces the diluted mixture into the hydrocyclone with a flow component directed toward the heavy fraction outlet. The hydrocyclone has a light fraction outlet at the same end as the inlet.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
130 words
A hydrocyclone separator having at one end an inlet for tangentially introducing into the separator a diluted mixture separable into two fractions and having at the other end an outlet for one of said fractions, wherein said inlet comprises an inlet nozzle connected to a first supply line for a concentrated mixture to be separated into said fractions and a second supply line for a diluting liquid, said first supply line and said second supply line being connected separately to said inlet nozzle, which inlet nozzle directs the flow into the hydrocyclone with one component of movement directed toward said outlet, said second supply line forming a substantially right angle to the principal axis of the hydrocyclone and said first supply line forming an obtuse angle to the principal axis.
Claim 2
Dependent Claim
130 words
A hydrocyclone separator having at one end an inlet for tangentially introducing into the separator a diluted mixture separable into two fractions and having at the other end an outlet for one of said fractions, wherein said inlet comprises an inlet nozzle connected to a first supply line for a concentrated mixture to be separated into said fractions and a second supply line for a diluting liquid, said first supply line and said second supply line being connected separately to said inlet nozzle, which inlet nozzle directs the flow into the hydrocyclone with one component of movement directed toward said outlet, said second supply line forming a substantially right angle to the principal axis of the hydrocyclone and said first supply line forming an obtuse angle to the principal axis.
Claim 3
Dependent Claim
16 words
The hydrocyclone separator recited in claim 1 wherein said obtuse angle is between 110° and 160°.
Claim 4
Dependent Claim
15 words
The hydrocyclone separator recited in claim 2 wherein said angle is substantially equal to 135°.
