Abstract

system element for combined tubular Filling and unloading bays for installation in silo cells for from below to be discharged free-flowing fracture-sensitive bulk materials with an inside smooth tube and an inlet / outlet opening with outside the wall on the vertical sides of the opening abkragenden side pressure plates Patent 197 05 933, characterized in that these side pressure plates on the vertical sides of the inlet / outlet opening (3) in any angular positions to their common median plane as whole or subdivided domed or kinked or straight-sided Collar off side pressure plates.

Description

I. Field of application

The Invention relates to filling and extraction shafts for installation in high silos for from above to be discharged bulk materials, the in height one above the other several inlet / outlet openings in the extraction shaft to the filling and removal always from above to ensure as described for example in DE OS 3923613.

object of the patent 197 05 933 C1 u. a. from the inlet / outlet openings parallel to the median plane abkragende side pressure plates, which along their vertical outer edges by a preferably large frontal pressure plate are connected and thus form a header shaft, which differs from the Area of the lower edge of the inlet / outlet openings up to the Area of its upper edge extends (claims 1-4).

The The present invention aims at an improvement and further development of this object of the parent application and proposes for different storage products advanced jack shells.

By a downpipe with a plurality of such stacked covered Inlet / outlet apertures is the filling and removal of bulk material possible in a silo from above, by taking bulk material when removing only over the top one with bulk material covered opening gets into the downpipe while the lower-lying openings are disabled and when filling bulk only over the lowest of the not yet covered by bulk material openings gets into the silo.

The The object of the invention is to optimally on the system element the characteristics and above all the resilience of the different ones Warehouse products by design of the attachment shaft and in particular adapt to the side pressure plates.

These The object is solved by the features of claim 1. advantageous embodiments emerge from the dependent claims.

While z. B. the side pressure plates according to the prior art, in the Main application, are indicated parallel to the median plane, around the pressure acting on the storage of the cell in the well deterred, it appears appropriate according to the invention that these side plates also in any angular positions to their common center plane as whole or subdivided domed, kinked or straight-sided Collar off side pressure plates. This enables the function of the system elements exactly to the Randbedigung for the respective product as well as the storage and retrieval services to adapt as needed.

exemplary embodiments are shown below with reference to the figures. Show it:

1 : a system element without frontal pressure plate in longitudinal section,

2 to 4 : Variants of side pressure plates,

5 : a system element with frontal pressure plate in longitudinal section,

7 to 8th : Front shafts with frontal pressure plate in different varinants,

9 : a system element with upwardly extended frontal pressure plate, and

10 : a supervision of the solution according to 9 ,

In 1 - 8th are shown according to exemplary embodiments. It can be seen that the power-determining feed cross-section of the attachment shaft 5 z. B. in an advantageous manner by the angle to each other outwardly opening side pressure plates 10 . 12 opposite the width of the inlet / outlet opening 3 can be increased, especially if he without jumping too far with curved frontal pressure plates 13 or bent side pressure plates 14 combined. The curvature of the frontal pressure plate 13 or the side pressure plates 10 or the use of divided side plates 12 allows the use of less expensive thin sheets, such. B. for stainless steel in the food industry.

For smaller cells, in which no high pressures of the stored material occur in the inlet / outlet openings of the shafts inside, according to the invention to the outside to the common center plane inclined side pressure plates 9 ( 3 ) proposed.

According to the invention, it is further proposed that any desired frontal pressure plates 6 so far over the top edge of the inlet / outlet opening that the in 9 illustrated and described in claim 5 angle α is steeper than the slope angle β of the stored material. With this embodiment it is avoided that the slope angle pressure of the goods obliquely from above into the inlet / outlet opening 3 into it.

It shows in practice that when drilling the holes for heavy duty anchors in concrete walls of the silo cells for wall mounting of the system elements met rebar can be. The registration requirement of the anchor prescribes an exact minimum distance for such cases for one offset the second hole.

According to the invention it is therefore further proposed that the push-over length of the outer tube 2 greater than the defined in the approval of the anchor respectively prescribed to be maintained Fehlbohrungsabstand for not shown here for Wandwinkelbefestigung serving heavy duty anchor.
