Abstract

1433253 Centrifugal separators and classifiers DONALDSON CO INC 1 June 1973 [12 June 1972] 26178/73 Heading B2P In a centrifugal separator, classifier, or scrubber or pneumatic conveying tube, a vortex is imposed upon a primary flow of particleladen gas by a vortex-forming device 20, Figs. I and 3, including an annular hub member 22 having spaced nozzles 34 leading to the periphery of the member and supplied with auxiliary gas under pressure, the nozzles being positioned to discharge jets of gas 36 whose axes lie in one or more planes generally perpendicular to the direction of primary flow and are generally tangential to the periphery of the member 22, the vortex created submitting the particles to centrifugal force thereby causing them to be separated or classified. The apparatus of Figs. 1 and 3 constitutes an air cleaner having a cylindrical housing 10, an open dirty air inlet end 11, an axially located clean air discharge tube 12 and dirt discharge tube 17 tangential to the housing and provided with a slotted automatic evacuator rubber valve 18. The annular hub member 22 forms part of a closed cylindrical casing 21 having end caps 21a, 21c and a tubular centre portion 21b. The casing 21 is mounted in the housing 10 by conduit members 24, 25. Conduit 25 is in communication with the interior of the casing and is connected to a compresor 27 which supplies air or other gas under pressure to the casing interior. The latter communicates with the nozzles 34 through L-shaped pockets 32 formed in the wall of the hub member. The nozzles 34 are formed as orifices in radially extending wall portions 33 of the hub member. Extending in a downstream direction from the innermost edge of each wall portion 33 is a ramp surface 35 that is curved in a radially increasing manner to enhance the attachment of the adjacent jet to the surface of the hub member thereby constricting the vortex created by the jets. In a modification, the dirty air inlet may be tangential to the housing 10. Fig. 8 shows a particle classifier with a vaned inlet 41 and a vortex forming device 42. Suction is applied by a blower 45 to a fine fraction outlet 46, the fine fraction being collected by a filter 47 and deposited in a container 48. The coarse 'fraction is drawn through a tangential outlet 49 by suction applied by a blower 50 and is separated by a filter 51 and deposited in a container 52. Fig. 10 discloses a reverse-flow air cleaner with an open top dirty air inlet end, a vortex forming device 56, a clean air outlet conduit 58 and a dirt collector 59. In the case of a scrubber, liquid is sprayed through the nozzles in conjunction with the air jets.
