Silo for storing and mixing dust-like, fine-grained and fluidable bulk goods.

摘要

The silo for storage and mixing of pulverulent, fine-grained and fluidisable bulk goods consists of a disc-shaped silo bottom (2) which is inclined slightly relative to the centre and above which a tray (3) of smaller diameter, which is similarly slightly inclined relative to the centre, is arranged with spacing. In the centre there is a preferably conical emptying chamber (5) above an outlet (6). The silo bottom, the tray and the bottom of the emptying chamber are fitted with air-conveying grooves. According to the invention, the possibility is to be provided of modernising existing flat-bottomed silos without special mixing devices. For this purpose, a tray having air-conveying grooves (13) is constructed in such a way that it extends far into the interior of the conical emptying chamber (5). In this case, a bottom sink (15) is produced in the region of the outlet and is covered by the emptying chamber (5). Covered emptying channels (4) which are likewise fitted with air-conveying grooves (12) are embedded in the tray (3). These emptying channels (4) run radially from the annular bottom section (10) left free on the outer circumference by the tray (3) up to the bottom sink (15) and thus into the emptying chamber (5).
