摘要:
The invention concerns a rotary drum (1), in which the hygienic status of separated, pourable cow manure solids (3) is modified by aerobic heating such that the solids can be re-used as bedding in cowsheds. The aim of the invention is that of achieving a high charge level of the drum (1), which lies horizontally for incorporation in an insulated container (2), with a filling level of 60-70 % being achieved. According to the invention, the loaded solid (3) is kept in a chamber (4,8) and is passed to the drum (1) only when there is no solid surrounding the chamber (4,8). An important element is a flap (4,9) of the chamber (4,8), which opens and closes in this area only. If there is solid material on the outside of the flap, then the flap is prevented from opening (4,9).

The invention relates to a heating unit for rock material, which is intended for heating and screening of rock material. The heating unit includes a rotating drum (10), conveyor devices (16) for feeding the rock material into the drum (10), a heat-developing unit (15), and a set of outlet screens (11) for screening the heated rock material. The drum (10) includes two coaxial jackets, an outer jacket (20) and an inner jacket (21). There is a fine screen (22) at the start of the inner jacket (21), through which the fines are arranged to travel to the space (23) between the inner and outer jackets and from there to the set of outlet screens (11).

Es ist ein Verfahren zum Trocknen und Kühlen von feuchtem Kristallzucker mit Hilfe einer langgesteckten Trommel in Form eines Trockners/Kühlers vorgesehen, mit dem die Trocknungs- und Kühlleistung wesentlich gesteigert werden kann, und zwar durch Aufgabe des feuchten Gutes in die Trocknungszone in Form eines den größeren Teil des Gesamtquerschnittes der Trommel einnehmenden dünnen Schleiers, der von der Trocknungsluft senkrecht angeströmt wird, während in der Kühlzone die durch Hubschaufeln angehobenen abrieselnden Zuckerteilchen in einem unterhalb der Trommelachse angeordneten Fluidisierungsbett aufgefangen und einer hohen Kühlwirkung unterworfen werden.

A tumbler may be used as defluidizer, dryer, coater, classifier, or dynamic filter. The tumbler includes a housing for rotatably supporting a removable screened drum on a plurality of rollers. The drum receives a solid/fluid slurry through an inlet chute. As the slurry travels through the drum, fluid exits the drum through a plurality of apertures in screens attached to the sides of the drum, while the solids continue along the drum's length until they reach one or more openings and exit the drum into an outlet chute. The outlet chute includes ridges that wrap around rings extending from the openings of the drum to prevent solids from escaping the outlet chute. To further dry the solids before they exit the drum, an air tube disposed within the drum is configured to direct air through the screens to an air blower intake positioned outside of the drum.

An autoclave (1) comprises a carrier framework (4) within which a drum (8) is rotatably mounted and rotated by a drive motor (12). The drum (8) defines a hollow interior region within which the waste material is treated, and an open mouth (15) at one end of the drum (8) is closed by a hingedly mounted closure member (16). The carrier framework (4) is pivotally coupled to a ground engaging mounting framework (2) by decoupleable first and second pivot mountings (5,6) at respective opposite ends (10,11) of the carrier framework (4) so that on release of the second pivot mountings (6) the carrier framework (4) and the drum (8) are pivotal about the first pivot mountings (5) by first main drive rams (19) from a horizontal operating state to an inclined loading state with the drum (8) inclined upwardly to the open mouth (15) for loading waste to be treated into the drum (8). On release of the first pivot mountings (5), the carrier framework (4) and the drum (8) are pivotal about the second pivot mountings (6) by second main drive rams (20) from the operating state to a discharge state with the drum (8) inclined downwardly towards the open mouth (15) for discharge of treated waste material from the drum (8).
