Abstract: A cellular wheel sluice, comprising a housing with an inlet opening and an outlet opening, side covers, a cellular wheel with a shaft, and the bearing of the shaft with fixed and loose bearing.

Abstract: The present invention relates to a method for operating a conveyor pipeline with pneumatic compact-flow conveying, and to an apparatus for performing the method. In this compact-flow conveying, a shunt line is disposed in a bypass around a conveyor pipeline; feed lines branch off from the shunt line and discharge into the conveyor pipeline at regular intervals via associated spill valves. With the aid of Laval ball valves, the apparatus makes a method possible in which by preventive, temporary increasing of pressure by associating and varying certain bypass air quantities at predetermined time intervals, air is additionally blown out into the conveyor pipeline via a determinable number of overpressure valves, so that even during bulk material conveying, the development of plugs can be avoided.

Abstract: A pipe shunt for pneumatically fed bulk goods, comprising a housing with three pipe connections associated with one another and one stopcock, rotatably supported in this housing by a pivot pin and connecting the three pipe connections with one another through two flow channels, each flow channel comprising one length of pipe and the two lengths of pipe being joined to one another in the region of the respective ends each via one adapter and in their middle via the pivot pin of the stopcock, characterized in that a pipe entrance disposed in the housing of the pipe shunt communicates with one at a time of the two pipe drains disposed in the housing through a flexibly embodied spiral hose that communicates with these pipe connections, is prestressed in curved fashion between them, and is disposed with a slide with supporting angle brackets.
