Definitions
- the invention relates to a roller body for a rotary drum with the generic features of claim 1 and a rotary drum with a roller body with the generic features of claim 5.
- the inventors have recognized that an effective process promotion in the rotary drum requires a particularly thorough cleaning of the front zone, i. H. the entry zone of the rotating drum, i.e. in an area in which the material to be treated has considerable gaseous and liquid components, is particularly important and that, on the other hand, cleaning the inner wall of the rotating drum in the rear area, in particular in the area of the discharge zone, in which the treated material, insofar as it does not remain gaseous, is essentially solid or is only relatively slightly moist, should be carried out in a manner which is as gentle as possible, in particular in such a way that the dust formation is kept as low as possible when the caking material is cleaned off.
- a rotating drum having a rolling element in which the rolling element is attached to the, in particular non-rotating part of the drum head with the interposition of a rotary joint connection and the rolling element has a front edge which, by means of the hitching device of the rotary joint connection in Area of a constricted edge of the rotating drum is held and thus intensive cleaning is possible not only in the cylindrical rotating drum part, but also in the transition area to the tapered rotating drum head.
- FIG. 1 shows a rotary drum in a longitudinal sectional view with a roller body in its entry-side region - in sections;
- the ball joint 25A is firmly connected to the cover 16 by means of a screw connection 26A and the ball joint 25B is firmly connected to an end wall 21A of the rolling element member 21 by means of a screw connection 26B.
- the end face of one rolling element member 21 has a central recess 28 into which the end face of the adjacent rolling element member 22 can at least partially immerse.
- the outer wall forming the conical zone 2IC of the first roller element 21 extends beyond the end wall 21A, in particular in alignment, and thus the distance gap to the second roller element 22 on the outside of the kink is largely covered to a greater or lesser extent.
- a face ring 29 is therefore shown in FIG. 1, merely by way of example.
- Rolling member 21 is formed in a club shape and has a first conical surface zone 2IC and a second conical
- a second rolling element member 22 can be connected to this first rolling element element 21 in a manner similar to that shown in FIG. 1; this is shown in dashed lines in FIG.
- each of the rolling element elements can also be provided with only one cleaning zone and individual rolling element elements can form an angle with one another which deviates from 180 ° and can be assigned to differently inclined rotary drum zones.
- FIG. 3 shows a conical first rolling element link 21, which in turn is fastened to a fixed end region of the rotary drum 10 by an intermediate link 24 designed as a chain and is connected in the center to the front end wall 21A via a cardan joint-like pivot joint connection 25.
- the end edge 21F formed between the front inner wall 21A and the conical outer surface 21B is arranged in the kink region between the conical and cylindrical conversion part of the rotary drum 10, so that the conical tapering zone is also cleaned, at least in the transition region.
- Such a cleaning effect also occurs if the cross-sectional tapering of the rotary drum 10 is not conical, but rather - as shown in dashed lines in FIG. 3 - is stepped.
