Definitions
- the invention relates to a drive device for a tube mill a rotatably mounted grinding tube with regrind and with a flying outside the grinding tube storage at the end of the regrind arranged frustoconical discharge cone, which at its small diameter is closed by an end wall, whereby the discharge cone for the discharge of the ground material and the mill gas has several discharge openings distributed around the circumference, which are enclosed in a stationary good failure housing.
- the regrind is at the end of the regrind as well as the grinding media containing the grinding media outside a conical discharge cone flying over the grinding tube bearing arranged by its small diameter by a End wall is closed, on the central drive shaft of the central drive attacks.
- the discharge cone is distributed around the circumference Openings for the discharge of the ground material and the mill gas on.
- the regrind and mill gas discharge openings are from a stationary good failure housing, in which the ground Falls well down and is carried down while the mill gas loaded with fine grain from the top of the stationary Good failure housing is withdrawn.
- the invention has for its object a for a tube mill to create a simple and compact drive device whose Power transmission through deflections and other deformations of the grinding tube is no longer at risk.
- the drive device In the drive device according to the invention is at the end of the regrind of the grinding tube attached frustoconical Discharge cone attached to its small diameter a drive wheel with a diameter ⁇ (smaller / equal) the grinding tube diameter.
- the one used for power transmission or torque transmission The drive wheel has a maximum diameter of that Grinding tube diameter, preferably smaller, so that the drive wheel in diameter clearly from the large sprockets the known sprocket drives differs.
- This comparatively small drive wheel is in the drive device according to the invention in a simple way on the small diameter of the Discharge cone flanged.
- the small drive wheel in diameter is according to an embodiment of the invention Diameter of small ring gear, which is initially characterized by a low weight and comparatively little effort distinguished for its production.
- deflections and other deformations occur of the grinding tube hardly on the small diameter drive wheel noticeable, causing the power transmission / torque transmission as well as the uniform tooth width load behavior in the case of the invention Drive device remain guaranteed.
- this is the smallest Not arranged diameter of the discharge cone drive wheel necessarily be designed as a ring gear, but the drive wheel can wear pole pieces and form an electromotive rotor, the contactless of a stator of a gearless ring motor drive is rebuilt.
- Ring motor is comparatively thanks to its rotor and stator small diameter accordingly simple and inexpensive to build.
- the ring motor drive is infinitely variable speed control, and the speed is optimal to the properties of the regrind as well as the mill sifter grinding system, in which the tube mill according to the invention is used.
- the ring gear and that are at least one Drive pinion enclosed by a stationary ring gear housing In the case of the ring gear drive, the ring gear and that are at least one Drive pinion enclosed by a stationary ring gear housing. It's just a single ring seal between the one Output cone facing the ring gear housing side wall and the small outside diameter of the discharge cone is required, because the other sprocket housing side wall is enclosed of the discharge cone end can be completely closed.
- the gear ring housing is easy to seal when circulating oil of the ring gear drive minimizes oil leakage and it even an oil immersion bath lubrication would be possible.
- the drawing shows a schematic section of the left end a tube mill with a mill tube rotatably mounted on the circumference or grinding tube 10, into the one to be ground from the right side Well, grinding media such as B. steel balls and mill air enter, that also applies to the drying of moist goods from a hot gas stream can exist.
- Grinding tube 10 is a flying cone-shaped discharge cone 11, via which the tube mill is described in the following is driven according to the invention.
- the small diameter of the frustoconical discharge cone 11 is followed by a cylindrical intermediate piece its end is closed by an end wall 14.
- On this end wall or to the left end of the discharge cone 11 with its Small diameter is a comparatively small T-shaped flange in cross section one-piece ring gear over its ring-shaped bridge flanged, with an outside diameter smaller than that Diameter of the grinding tube 10.
- One-piece, comparatively small gear rim that can be produced cost-effectively 15 comes with at least one drive pinion 16, which with Advantage is self-adjusting, in tooth flank engagement and with one Speed of z. B. driven about 12 to 18 U / min, namely a main drive, not shown, attached to the left side with two-stage reduction gear 17, with 18 a Auxiliary drive is displayed.
- the ring gear 15 and the at least one drive pinion 16 enclosed by a stationary ring gear housing 19, which with completely encloses the end of the tube mill on its left side wall and that with only a single ring seal 20 between the Discharge cone 11 facing the ring gear housing side wall 21 and the small outside diameter of the discharge cone.
- the drive device according to the invention is except for tube mills also applicable for other rotary drums, e.g. B. for tumble dryers or similar.
