CYCLONE DUST COLLECTOR.

Application filed October 11, 1922. Serial No. 593,820.

To all whom it may concern:

Be it. known that I, HERMANN KLUG, a citizen of the Republic of Germany, and resident of Bc-rlin-Hermsdorf, Germany, have invented certain new and useful Improvements in Cyclone Dust Collectors, of which the following is a clear, true, and exact specification, reference being bad to the accompanying drawing.

l leretofore, all dust collectors operating on the cyclone principle have been generally cylindrically, that is, circular in transverse cross section. cyclone dust collector is the most simple used, with a working coefficient of 80' to 85%, according to the character of the dust. In any event, the cyclone dust collector is most generally used.

A chief object of the invention is to improve upon present-day cyclone dust collectors; and with this end in view, a feature of the invention resides in substituting for the cylindrical casing heretofore in use (generally of sheet iron), a casing of any material whatever (iron, wood,-masonry, etc.), with square or rectangular cross section.

Among the advantages of the present invention, the space for the cyclone path is utilized to a far greater extent, as it is square or rectangular cross section. Apart from this, the dead corners, which are always present in cyclones, may, according to the present invention, be utilized ,to advanta e and with technically good effect.

It 1s furthermore possible to make the new construction ofmasonry, or other much cheaper material than the expensive sheet Finally, the operation is much'less noisy, as the noise caused by heavy materials, such as shavings and the like, falling against the sheet metal walls is eliminated.

ltn the drawings, Fig. 1 is an elevation showing the air or gas inlet opening. Fig. 2 a horizontal section through Fig. 1; and

Fig. 3 is a vertical section, showing the filter for fine dust.

Dust-laden air or other gas is adapted to It is well known that the to the direction of travel of the entering air or other gas. I The battle wall is disposed in the horizontal plane of the inlet opening b, near the said one wall, and is adapted to cause the entering current of dust-laden air'to deviate its course. The casing a is polygonal in cross section, preferably square or rectangular, or some other polygon having a relativelysmall number of sides. The interior of the casing, near the battle plate, is unobstructed in the horizontal plane, so as to permit a circular movement of the dust-laden air, as shown by the arrows, in a path determined by the angular position of the bathe late. The dead. corners, during the whirling of the dust-laden air, prove particularly effective separators for the dust from the dust-laden air. Their eliicacy may be considerably enhanced by built-in walls or catch plates 6 that extend from the cor- 4 ners inward towards thewhirling dustladen air. The catch plates 6 make it certain that the dust thrown against them shall be directed towards the calm regions of the dead corners.

Should it be desired to purify the gas,

the cover 9 of the rectangular or square dust tion, a substantially vertically disposed casing polygonal in cross section, the polygon havingarelatively small number of sides, the casing having an inlet openin through which dust-laden air or other gas is adapted to enter the casing, and a battle plate disposed within the casing near the inlet opening at an angle to the direction of travel of the entering gas, the battle plate being adapted to deviate the path of the entering gas, the interior portion of the casing near the baffle plate being unobstructed from the center of the casing to the sides thereof so as topermit the gas to whirl therein in a path determined by the angular position of the battle plate, dust being adapted to be removed from the whirling dust-laden gas at the corners of the casing, and the gas being then adapted to travel to the upper portion of the casing.

2. A dust collector having, in combination, a substantially vertically disposed cas- Eli ing of square or rectangular cross section, one of the walls of the casing being provided near a corner of the casing with a relatively small inlet opening through which dustladen air or other gas is adapted to enter the casing, and a baflle plate substantially vertically disposed within the casing near to and substantially in a horizontal plane with the inlet opening near a wall adjacent to the said one wall at an angle to the direction of travel of the entering gas, the bafile plate being adapted to deviate the path of the entering gas, the interior portion of the casing in substantially the horizontal plane of the inlet opening and the baffle plate being unobstructed from the center of the casing to the sides thereof so as to permit the gas to whirl therein in a path determined by the angular position of the baflle plate, the angular position of the bafiie plate being adjustable to adjust the path of travel of the whirling gas, dust being adapted to be removed from the whirling dust-laden gas at the corners of the casing, and the gas being then adapted to travel to the upper portion of the casing.

3. A dust collector having, in combination, a substantially vertically disposed casing polygonal in cross section, the polygon having a relatively small number of sides,

the casing having an inlet opening through which dust-laden air or other gas is adapted to enter the casing, a baffle plate disposed within the casing near theinlet opening at an angle to the direction oftravel of the entering gas, the baffle plate being'adapted to deviate the path of the entering gas, the interior portion of the casing near the baffle plate being unobstructed from the center of the casing to the sides thereof, so as to permit therefrom,

the gas to Whirl therein in a path determined by the angular position of the bafile plate, and catch plates at the corners of the casing extending from the corners inward towards the whirling dust-laden air to remove dust the gas being then adapted to travel to the upper portion of the casing, and the removed dust being adapted to fall to the lower portion of the casing.

4. A dust collector having, in combination, a substantially vertically disposed casing polygonal in cross section, the polygon havmg a relatively small number of sides, the cas ng having an inlet opening through which dust-laden air or other gas is adapted to enter the casing, a bafiie plate disposed Within the casing near the inlet opening at an angle to the direction of travel of the entering gas, the baflie plate being adapted to deviate the path of the entering gas, the interior portion of the casing near the baffle plate being unobstructed from the center of the casing to the sides thereof so as to permit the gas to whirl therein in a path determined by the angular position of the bafiie plate, dust being adapted to be removed from the whirling dust-laden air at the corners of the casing, and the gas being then adapted to travel to the upper portion of the casing, and one or more fine-filtering layers in the upper portion of the casing for purifying the gas as the gas travels upward, the fine-filtering layers being adapted to be cleaned from time to time.

In testimony whereof I herewith afiix my signature in presence of two witnesses.
