Patent ID: 8501019

Claim:
A device for separating fluid mixtures, comprising a vacuum chamber (V), a fluid supply (FZ) through a truncated-cone round jet nozzle (K), a fluid outlet (FA) in the bottom area of the vacuum chamber for discharge of the dried fluid by means of a fluid pump (FP), a gas outlet (GA) that is connected to a vacuum pump (VP), a controllable gas entry (GE), characterized by that the truncated-cone round jet nozzle (K) is composed of a tube (R) with a closed end (E), wherein the tube (R) has a tapered portion before the closed end (E), wherein the tapered portion of the tube reduces the diameter of the tube to 90-30% of the entry diameter (R D ), 2-8 holes (L) as exit openings arranged orthogonally to the flow direction (SR) in the area of the tapered portion, wherein the holes (L) respectively have a diameter (L D ) between one twentieth and one half of the tube diameter at the taper (R J ), a first cap nut (M 1 ) having an outer diameter of 1.25-2.5 times the tube diameter at the taper (R J ) with a shoulder-type tapered portion, wherein the shoulder has a height of 0.1-10 mm and a width of 90-70% of the original diameter, a second cap nut (M 2 ) having an outer diameter of 1.25-2.5 times the tube diameter at the taper (R J ), with a conical shape, wherein the height of the conical portion (K H ) is between 0.01 and 10 mm and the cone angle (φ) is between 10° and 80°, wherein the first and the second cap nuts are arranged at the tube in such a manner that in the area of the holes, a gap (Sp) of 0.01 to 10 mm width (Sp b ) is formed.
