Abstract
Abstract Air separator with cylindrical housing for the separating chamber and with an inwardly located radial impeller, in which a plurality of outwardly located cyclones are, by means of entrance passages, arranged behind the radial impeller in such a way that the direction as well as the magnitude of the absolute exit velocity of the separating air will when entering the entrance passages not be subjected to any change.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
211 words
A circulating air separator with a closed circuit path for separating air which includes: housing means substantially cylindrical over the entire length thereof and having a distributing cone located centrally therein by way of which separating material is centrally supplied while defining separating chamber means therewith where separation of separating material occurs into coarse material and fine material by way of separating aIr based upon equilibrium principle, an internal radial impeller means arranged at the upper end portion of said separating chamber means above said distributing cone, motor means drivingly connected to said impeller means for rotating the same, a plurality of cyclones arranged outside said separating chamber means, inlet conduit means interconnecting said cyclones with said separating chamber means and leading in the direction of absolute exit velocity of separating air behind said radial impeller means so that both the direction and also the magnitude of the absolute exit velocity of the separating air during entry into said inlet conduit means experience no alteration, and immersion pipe means extending into the lower portion of said cyclones, and additional conduit means establishing communication between said immersion pipe means and the lower portion of said separating chamber means, said additional conduit means being connected angularly adjacent said housing means forming a cascade.
Claim 2
Dependent Claim
211 words
A circulating air separator with a closed circuit path for separating air which includes: housing means substantially cylindrical over the entire length thereof and having a distributing cone located centrally therein by way of which separating material is centrally supplied while defining separating chamber means therewith where separation of separating material occurs into coarse material and fine material by way of separating aIr based upon equilibrium principle, an internal radial impeller means arranged at the upper end portion of said separating chamber means above said distributing cone, motor means drivingly connected to said impeller means for rotating the same, a plurality of cyclones arranged outside said separating chamber means, inlet conduit means interconnecting said cyclones with said separating chamber means and leading in the direction of absolute exit velocity of separating air behind said radial impeller means so that both the direction and also the magnitude of the absolute exit velocity of the separating air during entry into said inlet conduit means experience no alteration, and immersion pipe means extending into the lower portion of said cyclones, and additional conduit means establishing communication between said immersion pipe means and the lower portion of said separating chamber means, said additional conduit means being connected angularly adjacent said housing means forming a cascade.
Claim 3
Dependent Claim
44 words
An air separator according to claim 1, in which said cascade is stationary, and which includes movable blades extending into said separating chamber means, said blades being adjustable so as to form different angles with regard to the circumference of said separating chamber means.
Claim 4
Dependent Claim
63 words
An air separator according to claim 1, in which control means formed by flap means which are pivotally mounted in said inlet conduit means of said cyclones and operable selectively to vary the effective cross-section through which said inlet conduit means communicate with said cyclones, said flap means being adjustable from a minimum cross-sectional value to a maximum value thereof and vice versa.
Claim 5
Dependent Claim
40 words
An air separator according to claim 3, which includes additional flap means arranged within said additional conduit means and operable for selectively varying and controlling the free cross-section establishing communication between said additional conduit means and said separating chamber means.
Claim 6
Dependent Claim
120 words
An air separator according to claim 3, which includes conical discharge means connected to the lower end of said housing means, pipe means substantially coaxially arranged fixedly within said housing means and in radially spaced relationship thereto, said pipe means extending from a portion of said conical discharge means into the vicinity of said radial impeller means, said distributing cone communicating with openings in said pipe means at a level intermediate said impeller means and said cascade, and conveying means leading radially from the outside into said housing means and ending above said distributing cone, said pipe means being provided with opening means for passing coarse material and separated material to be withdrawn from the separator through said opening means.
Claim 7
Dependent Claim
83 words
An air separator according to claim 3, in which said control means also include additionally flap means arranged in said additional conduit means, said separator also including adjusting means operatively connected to said flap means and responsive to the speed of said radial impeller means for controlling said flap means to maintain substantially constant the diameter of the finish separated granules, the diameter of the vortex and the circumferential speed of the twist flow on the outer marginal area of the distributing cone.
