DD211530A1 - OUTGOING DEVICE FOR SELF-DEPOSITION OF SILO CELLS - Google Patents

Abstract

There are known outlet devices that allow self-emptying in the silo cells and thereby cause an eccentric load. There are further known emptying devices in which the Schuettgut is removed by a perforated zetrisches emptying tube superficially, which requires a relatively high design effort. The aim of the invention is the elimination of the aforementioned disadvantages. According to the invention, this object is achieved in that tube-shaped connections are produced between one or more inlet cross sections and the outlet cross-section, the outlet cross-section preferably being guided in the silo cell outer wall and the inlet cross-section or sections leading to the points in the silo cross-section which allow optimum emptying of the article to be cast, in particular the load entry due to emptying pressure. This means that the inlet cross-sections and outlet cross-section of the outlet device are at a constant, well-defined distance, the geometry of the silo cell and the type of Schuettgutes are taken into account in the determination of the distance.

Description

title

Outlet device for automatic emptying of silo cells

Field of application of the invention,

The outlet device is to be used in silo cells of the known constructions, in particular in reinforced concrete silo cells, in which, in addition to the outlet on the cell floor, a further outlet device in any height of the silo cell is required as automatic rapid emptying.

Characteristic of the known technical solutions

2s outlet devices are known in which the inlet cross-section and the outlet cross-section are directly above one another or, next to each other.

Furthermore, discharge devices are known in which a superficial discharge of the bulk material occurs via a perforated discharge tube tuned to the crown size of the bulk material, so that the distance between inlet cross-section as a function of the degree of sintering of the silo cell is increasingly reduced

 Disadvantage of the former discharge devices are increased local loads of the silo cell wall in asymmetric arrangement in the wall area.

iJachteil the second outlet device is a high constructive 'effort for reaching over the entire height ^{1 of} the silo nendeserungsrohr and its support in the silo cell.

Object of the invention

The aim of the invention is the elimination of the aforementioned disadvantages.

Pur existing and newly to be built silos is to create the possibility to arrange according to the user-technological requirements preferably on the silo outer wall additional automatic discharge devices.

Explanation of the essence of the invention

With the invention, the problem to be solved is that despite asymmetric position of the outlet device in the wall region of the silo cell no eccentric emptying of the bulk material, d, h, no increased local load of the silo cell wall, according to the invention the object is achieved in that between one or more Zulaufquerachschnitten and the outlet cross-section tubular connections are made, wherein the outlet cross section is preferably in the silo cell outer wall. The inlet cross section is guided to one or more points in the silo section, so that an optimal emptying of the bulk material is secured in particular with regard to the load application due to emptying pressure. This means that inlet cross-sections and outlet cross-section of the outlet device are at a constant, precisely defined distance, whereby the geometry of the silo-cells and the type of the bulk material must be taken into account when determining the distance.

embodiment

The invention will be explained below using an exemplary embodiment.

In a silo tract of reinforced concrete round cells 3 emptying devices for the automatic direct loading of vehicles are preferably required in the outer cells 1 in addition to the emptying hopper 2 in the cell bottom. According to the invention, a drainage pipe 4 is guided by the silo cell outer wall 5 with the required for the bulk material slope to the opposite wall and placed there. For the inflow of the bulk material 6, one or more inlet openings 7 are arranged taking into account static requirements in the emptying tube 4 so that the bulk material 6 as possible for emptying via the emptying hopper 2 in the cell bottom 3 as symmetrical as possible from the silo

flows out · Depending on the design of the silo it is also possible to mount the inclined discharge pipe upwards or to support it downwards.
