Der vorliegende Zyklon gehört zu den bekannten Vorrichtungen dieser Art, bei denen die Luft am Umfang eingeführt und achsial abgeführt wird, wobei sich der ausgeschiedene Stoff in einem trichterförmigen Rumpf ansammelt. The present cyclone is one of the known devices of this type in which the air is introduced at the periphery and axially discharged, whereby the excreted Fabric accumulates in a funnel-shaped hull.

Eingang des schneckenförmigen Kanals vorgesehen, dann geschieht diejrennung hauptsächlich in dieseiri_Einführungjkanal In some cases a narrow channel of uniform QwcTsdmittlrTaaieixnTrH ^ aiKMn radius before the. Intake of the helical channel is provided, then the opening takes place mainly in this introduction channel

Das äußere Gehäuse A des Zyklons besitzt einen Ejnführungskanal B und einen zentralen Ausführungskanal C. Die austretende Luft wird durch eine an sich bekannte Prallplatte D radial nach auswärts geführt. Der ungefähr eine halbe Umdrehung lange Einführungskanal ~E hat"~nür vorT7^r' bis G (Fig. 2) gleich- mäßigen Querschnitt uncTgTeicfFen Radius und geht dann in den schraubenförmiger^ „Kaiia'- H. van___wachsendem Querschnitt über, der sich rund um da's'liiTttfere Äuslaßrohr C windet und am unteren Ende desselben mündet. Dieser sich erweiternde Kanal H wird durch schneckenförmige Teile gebildet, die zwischen dem äußeren Gehäuse A und dem mittleren Auslaßrohr C angeordnet sind.The outer housing A of the cyclone has an inlet duct B and a central outlet duct C. The exiting air is guided radially outward by a baffle plate D known per se. The approximately one-half turn long introduction channel ~ E has "~ Nur vorT7 ^r 'to G (Fig. 2) uniform cross-section at the same uncTgTeicfFen radius and then goes into the helical ^" over Kaiia'- H. van___wachsendem cross section around around da's'liiTttfere Äuslaßrohr overcomes C and opens at the lower end thereof. This widening channel H is formed by helicoidal parts which are arranged between the outer housing A and the intermediate exhaust pipe C.

into the widening canal //. where the speed gradually decreases until the air at an open part of the cyclone leaves the duct at the same height as the mouth of the outlet opening C. This opening has, as indicated, a larger diameter at the top than at the bottom, consequently the air speed is reduced at. Passage through this tube both in the axial and in the circumferential direction, in the axial direction inversely proportional to the increase in the area of the tube and in the circumferential direction inversely proportional to the increase in the diameter of the tube.

Finally the speed is still reduced

'Reduced by the fact that the air must pass between the flat surface of the cyclone and the distribution disc J). The secreted substances get through the helical channel // into the body K of the cyclone. The important advantages of the present apparatus are as follows: There is only a narrow stream of air to cross from the heavy parts, which are thrown outwards by centrifugal force, and furthermore, the heavy parts are guided to the lower end of the apparatus by the inclined Casing. The 'back pressure is. diminished by reducing the confusion. ns in the channel // ,. and at the same time the well-known advantages of non-interference between the incoming and the circulating air are achieved. In addition, by reducing the speed of the air, the helical, widening channel transforms most of the air flowing through the. Movement generated aerodynamic energy in static pressure. It is known to arrange a baffle plate over the outlet opening on apparatus of this type and also to use an outlet pipe with increasing diameter; It is therefore not claimed to protect such devices per se or separately from the invention.
