Conveyor device for pneumatically conveying bulk material

A conveyor system with a conveyor device (1) for pneumatically conveying bulk material, comprising:

• a main conveyor pipe (3),
• a plurality of bypass conveyor pipe sections (5;
• 28;
• 30;
• 36;
• 39 to 41;
• 44 to 46), which are separate from one another, arranged one behind the other within the main conveyor pipe (3) and the main extent direction of which runs along the main conveyor pipe (3), each of said plurality of bypass conveyor pipe sections comprising:
• a stadium-shaped inlet opening (6) for conveyor gas to enter the bypass conveyor pipe section (5;
• 28;
• 30;
• 36;
• 39 to 41;
• 44 to 46), and
• an outlet opening (7) for the conveyor gas to leave the bypass conveyor pipe section (5;
• 28;
• 30;
• 36;
• 39 to 41;
• 44 to 46),
• wherein when the main conveyor pipe (3) is installed, in main conveyor pipe segments with a horizontal course component of the main conveyor pipe (3), the inlet opening (6) is arranged in a cross sectional portion of the main conveyor pipe (3), which is located above a cross sectional portion of the main conveyor pipe (3), in which the outlet opening (7) is arranged.
