Abstract
A conveyor device is used for the pneumatic conveying of bulk material. The conveyor device has a main conveyor pipe and a plurality of bypass conveyor pipe sections which are separate from one another and arranged one behind the other within the latter. The main extent direction of the bypass conveyor pipe sections runs along the main conveyor pipe. The bypass conveyor pipe sections in each case have an inlet opening and an outlet opening for conveyor gas. The inlet opening, when the main conveyor pipe is horizontally installed, is arranged in a cross sectional portion of the main conveyor pipe, which is located above a cross sectional portion of the main conveyor pipe, in which the outlet opening is arranged. The result is a conveyor device, of which the efficiency, in other words the ratio of the conveying power and the conveyor gas quantity used, is improved.
