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.
- Rotary drums also known as rotary tubes, are used in various heat treatment processes, such as drying, smoldering and many others, with direct or indirect heating of the drum interior that is to be treated. Because of the tendency of many items to be treated to stick to the inside of the drum, cleaning devices are used in the interior of the drum.
- rolling elements lying loosely in the interior of the rotating drum are known, which, as a rule, have projections for cleaning, such as helical strips, on their lateral surface and, by their design and / or support in the rotating drum, carry out relative movements to the inside of the rotating drum under cleaning action.
- Such rolling elements and such rotating drums are described in DE 36 41 731 AI.
- the coke that is produced passes through a plastic state and forms viscous caking on the drum wall in this zone.
- the caking reaches the solid state.
- caking from dust-laden cracking products occurs, which hinder the material entry.
- the invention is therefore based on the object of providing a solution with which the wall area of the entry zone a rotary drum is cleaned particularly effectively. If possible, the cleaning device should avoid excessive dust formation in the rear drum area.
- a novel rolling element is proposed according to claim 1, which is formed in one or more sections and has at least two cleaning zones which, viewed in the axial direction of the rotary drum, clean inner wall surfaces at an angle to one another, at least in the entry zone of the rotary drum, and the single- or multi-membered rolling elements on its end facing the drum entry side has a fastening device which has a swivel connection, by means of which the rolling elements can be fastened to an, in particular non-rotating, assembly of the rotating drum head, in particular to a cover.
- a rolling element according to the invention can in particular be formed in one or two parts, with the two or more-part design the rolling element elements lying one behind the other being connected in such an articulated manner that the axes about which the individual rolling elements essentially rotate can be at an angle to one another.
- Such articulated connections are preferably also suitable so that the angular velocity at which the individual rolling element members rotate can vary from rolling element member to rolling element member.
- multi-membered rolling elements seen parallel to the axial direction of the rotating drum, can perform a serpentine movement, so that the entire rolling element can also perform a dog-tail-like spiraling movement in addition to the rotary movement about the rolling element axis / axes.
- 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.
- ball joint connections are particularly advantageous as swivel connections
- cardanic and flexurally elastic swivel connections can also be used.
- the rotary drum designated overall by 10 in FIG. 1, is only shown schematically, in particular without insulation, heating and rotating devices. It consists of a cylindrical conversion part 11 and, at the two ends, a conical conversion part 12 and a flange 13 which is rotatably and sealingly mounted on a non-rotatable cover 16 in a known manner by means of bearing and sealing means 14 and 15.
- the insulation, heating and rotary Driving means of the rotary drum are known per se and omitted in the drawing, since they do not form part of the subject matter of the invention.
- the cover 16 is provided with a material feed 17 and a gas extraction nozzle 18.
- 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 intermediate member 24 is designed as a conical hollow body which tapers in cross-section towards the cover 16 and whose outer peripheral surface (jacket) is kept at a small, approximately constant distance from the conical conversion part 12 of the rotary drum 10. Caking that is thicker than the thickness of the spacing gap 24A can therefore generally not develop, so that the intermediate member 24 largely assumes the function of a second rolling element member 22.
- this intermediate or second rolling element member 24, 22 can also be provided with cleaning elements near the surface, such as are realized on the first rolling element member 21 in the form of the spiral cleaning strip 27.
- the conical zone 2IC has a cleaning effect (similar to the case with the intermediate element 24 or the second rolling element element 22). Cleaning elements can of course also be provided to enhance the cleaning effect.
- the rolling element member 21A therefore cleans two surface zones of the rotary drum 10, which are at an angle to one another, in a single work step and also detects the transition region of these two surface zones.
- 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.
