DE2362153A1 - Discharge rotary wheel for conveying bulk materials - is segmented with blades having sealing fit in housing - Google Patents

Abstract

The segmented wheel runs in the hollow space of a housing the individual blades of which have a sealing fit to the housing as in 2350033. The hub shaped centre piece of the segmented wheel is rigid and the blades, angularly curved, have a rotatable bearing around bolts extending parallel to the longitudinal axis, with the bolts attached at least at one end to a side plate turnable and drivable around the longitudinal axis of the wheel. During rotation of the plate the flexible blades are pressed under spring pressure against the housing inner wall at least during part of rotation and alternately against the outer wall of the hub shaped centre piece.

Description

The invention relates to a cell lock in which a cellular wheel is located in the cavity of a housing runs, the individual wings of which lie tightly against the housing, according to patent. · ...... (patent application

P 23 50 033.6).

The main patent aims to reduce wear and tear the rotary vane to reduce and an automatic To achieve readjustment of the worn wings. This is supposed to mean longer running times the cell lock between the interruptions required to readjust or replace the blades are to be achieved.

To solve this problem, the main patent suggests that the wheel blades are flexible and slightly bent, resiliently against at least part of the inner wall of the housing or one on the Place the sealing lining on the inside wall of the housing. This is based on the previously common type of cellular wheel: a rotating, hub-shaped one Middle piece to which the flexible wings are attached.

The present invention aims to provide an arrangement with which the blades can be changed even more easily are. The stripping and self-adjusting effect of the wings should be further improved will.

For this purpose, it is proposed that the hub-shaped center piece of the cell wheel is stationary and the Wing, bent at an angle, rotatable about bolts running parallel to the longitudinal axis of the cell lock are mounted, the bolts with at least one end on a lateral, about the longitudinal axis the cell lock rotatable and drivable disc are attached, when turning the Disc in at least one sense the flexible wings at least ^ during part of the revolution on the one hand, resiliently to the inner wall of the housing, on the other hand be pressed resiliently against the outer wall of the hub-shaped middle piece.

It has proven to be useful to provide an auxiliary spring on each wing, which together

forms with the wing a receiving opening for the corresponding bolt. It is advantageous to continue the wing ends grazing over the inner wall of the housing and the outer wall of the hub-shaped center piece bend so that they are at an obtuse angle, if possible with an edge, onto the corresponding On walls. . '

The invention will now be explained in more detail with reference to an embodiment shown in the drawing; show it '■

Figure 1 is a longitudinal section

Figure 2 shows a cross section through an embodiment the invention. : ..: ..

The housing 1 of the cell lock has at the top an opening 2 for feeding in the bulk material, the cell lock through the lower opening 3 leaves again.

The cellular wheel is formed by the individual, angled blades 7. The hub-shaped with * - middle piece 8 does not rotate with; it is firmly connected to the housing 1. The wings 7 are therefore also not attached to this center piece 8, but slide sealingly under light spring pressure on the outer wall 11;

• The wings are rotatably supported and moved by the bolts 12 on which they are individually

are attached. The bolts 12 run parallel to the longitudinal axis of the cell lock and are in turn attached to the side disk 14 at one end. The disc 14 is about the longitudinal axis of the Cell lock rotatable and driven by the shaft.

If the disk 14 and thus the bolts are rotated about the longitudinal axis of the cell lock, so the wings 7 try to rotate around the bolts 12. This rotation of the wing 7 is but for a sense of rotation is prevented by the fact that the wing ends on the housing inner wall 4 or the outer wall 11 of the hub-shaped center piece 8 come to rest.

Since the housing 1 is oval, the wings 7 are only under tension in the vicinity of the points 9 and 10. Near the top opening 2 and the bottom opening 3 they can easily be rotated around the bolts 12 in one sense. Here they can - after lifting the front wall 15 - easily pulled off or attached will.

The attachment is also made possible by the auxiliary springs 17 relieved. They define the axis of rotation of the wings 7 around the bolts 12 more precisely. In addition, the resulting spring force of the entire wing arrangement can be modified by them.

The wings 7 are slightly bent at their ends so that they are at an obtuse angle, if possible

with an edge that meets face 4 and 11. This improves the wiping effect.

The end walls 15 and 16 are from the bolts 12 and pressed against the wings 7 by elastic rings 1g. They run while turning of the cell wheel and slide - to reduce friction - over metal rings that are applied to the elastic rings 18.
