A dryer is provided. The dryer may include a main body having an inner space formed therein, a support body arranged in the main body so as to form a frame of the main body, a flexible drum rotatably installed on the support body so as to have a non-circular cross-section as it is rotated, and rotation guides arranged between the support body and the flexible drum so as to guide rotation of the flexible drum. A distance from a center of rotation of an inscribed circle contacting the inner circumferential surface of the flexible drum to one random point on the inner circumferential surface of the flexible drum is greater than a distance from the center of rotation of the inscribed circle to another point on the inscribed circle such that the drum maintains a non-circular cross section.

The invention relates to a roller support system for supporting a rotatingly driven tubular body so that it can be tilted, axially displaced and rotated. The inventive roller support system comprises two rollers that are disposed symmetrically on both sides of the longitudinal center plane of a vertical tubular body and that are received by two pivot bearings that are fastened so as to be tilted on a bearing plate that is supported on a stationary foundation. The aim of the invention is to allow for an optimum and smooth self-adjustment of every roller. To this end, every bearing plate is supported on the foundation via two pivot bearings that are disposed at a transversal distance to each other. The inner pivot bearing is configured as a ball-joint bearing and is stationary fastened on the foundation while the outer pivot bearing is configured as a free bearing and is supported on the foundation to be slideably movable about the joint center of the inner pivot bearing.

An apparatus (10) for rotating a drum (12) employs a plurality of drive sprockets (20) disposed about the outside surface (14) of the drum (12) and spaced-apart along the length of the drum (12). Each drive sprocket (20) has a first flange (22a), a second flange (22b) and a plurality of pins (24) interconnecting the first flange (22a) and the second flange (22b), spaced-apart about the drum (12) and parallel to the axis (16) of the drum (12). Spaced-apart hydraulic rams (30) each exert a force on one of the drive sprockets (20) so as to cause rotation of the drum (12). Each ram (30) is movable between a linearly retracted first state (A) and a linearly extended second state (A') and has a first end (34) and an opposite second end (32). The first end (34) is secured to the base (18), the second end is engageable with the pins (24) of a selected drive sprocket (20) so that as the ram extends from the first state (A) to the second state (A'), the ram exerts force on a pin (24) in the first direction (B), the first direction (B) being tangential to the outside surface (14) and perpendicular to the axis (16) of the drum (12). Force from the rams (30) is transferred to the drum (12) through the pins (24), the first flange (22a) and the second flange (22b). A plurality of spaced-apart ratchet stops (40) prevent movement of the drum (12) in a direction opposite the first direction (B). Torque applied to the drum (12) by the rams (30) is distributed along the length of the drum (12) at each of the plurality of drive sprockets (20).

摘要:
System for supporting and/or driving a rotatable drum (1), in which as seen along the longitudinal axis of the drum it is supported by at least two separated support and/or driving devices, in which each support and/or driving device comprises at least three belt guiding rollers (9, 10, 11) positioned at a defined distance from the drum circumferences and corresponding number of belts (12, 13, 14), each belt extending around the circumference of the drum and one of said guiding rollers.

The invention concerns support device (1) for a cylindrical drum (2) such as, for instance, an oven, drier, cooler or the like, designed for thermal and/or chemical treatment of materials, comprising at least a track roller (3), co-operating with said drum (2), and at least two bearings (5, 5') for enabling said roller (3) to rotate about its rotation axis (4). The invention is characterised in that the device further comprises: a frame (7), whereto said bearings (5, 5') are secured, mounted articulated about a pivoting axis (11) substantially perpendicular to the plane passing through said roller (3) rotation axis (4) and perpendicular to the block (6) on which said device (1) is placed, called articulating plane; linking means, flexible along a predetermined direction (9, 9'), called flexibility direction, and rigid in the directions orthogonal to said flexibility direction (9, 9'), to maintain said bearings (5, 5') on said block (6) while allowing the frame (7) to move freely in articulation, such that the roller (3) is aligned with the drum (2) when the latter is pivoting.
