Definitions
- the invention relates to an air classifier with a against its centrifugal direction from the visible air from the outside rotating flow-through wheel with a ring shape arranged blades running parallel to the axis of rotation, the between a circular disc and the bearing wheel hub an annular cover plate are arranged. It affects a classifying wheel for such an air classifier that is made entirely a wear-resistant sintered material is produced.
- a classifying wheel of the required type is for example the DE-PS 41 40 656 become known.
- This classifying wheel the circular disc with hub, the cover disc and the between this arranged, extending parallel to the axis of rotation Buckets made in one piece.
- the hole is in the hub with a semicircular in cross section trained groove for receiving a correspondingly shaped Feather key for torque transmission to a finished dimension for the immediate mounting of the sight wheel on his Machined drive shaft.
- the flow channels between the Buckets are made by parallel to each other and in the direction of Axial surfaces of the blades formed in the Transition area to circular disk or cover disk by a Arc surface are interconnected. With this kind of Training can be relatively high Achieve manufacturing accuracy that balances the finished processed sight wheel makes unnecessary.
- classifying wheel that is simple designed cylindrical ring elements is composed, the one another by a in joints between the ring elements introduced, solidifying filler are connected and processed to finished size before assembly and be balanced.
- the main part of the classifying wheel is a piece of pipe, the Outside dimensions the main dimensions - diameter and height - of the sight wheel. In this pipe section are radial directed, evenly distributed over the circumference Flow channels incorporated, their boundary surfaces run parallel to each other and in the direction of the axis of rotation and at both ends by an arc surface with each other are connected so that classifying blades with themselves radially inside tapering cross section.
- the axial distance an arc surface to the adjacent end face of the pipe section is at least equal to the thickness of the sight wheel hub bearing circular disc or the annular cover plate, the both are inserted into the pipe section so that their outside lying face and the corresponding face of the Pipe piece form a plane.
- the axial position of the circular disc and cover plate can by a in the pipe section incorporated, ring-shaped stop surface or through Formation of the surfaces delimiting the soldering or adhesive joints be determined as conical surfaces. In a similar way the connection between the hub and the circular disc is carried out.
- the advantage of the training shown is that critical areas of tension, especially in the transition area between circular disc and pipe section, eliminated or so far can be mitigated that the tensions occurring in the stay safe area and risk of breakage due to Cracking is eliminated.
- a higher manufacturing accuracy, especially with classifying wheels with outside diameters over 250 mm, is achieved in that the individual parts as simple designed ring elements are formed that are inexpensive machined to finished dimensions before assembly and can be balanced.
- the classifying wheel 1 consists of hub 2, circular disc 3, cover plate 4 and pipe section 5. All these parts are made a sintered material and are made before Assembling mechanically processed to finished dimensions (preferably ground) and balanced. Since it is simple ring elements are high Manufacturing accuracy achieved.
- the pipe section 5 is on both Ends with offset to the center of rotation 6 Provide indentations for receiving circular disk 3 or cover plate 4 serve and a width corresponding to the Have thickness of the recorded disc, so that for the Sight wheel result in flat, stepless end faces on both sides.
- the hub 2 the bore with a cross section semicircular feather keyway (9) is centered in inserted the circular disc 3, being offset by its Outer circumference is determined their axial position.
- an adhesive is used, e.g. a Two-component adhesive that is in the joints 10, 11 and 12 at Joining the parts is filled.
