Conveying system sealed off from the surrounding atmosphere

A conveying system comprising:

• a plurality of conveying cells (14) for accommodating bulk or loose material, wherein each of said conveying cells (14) includes a bottom (16), a front wall (30) and a rear wall (31) as viewed in a conveying direction of said conveying system, and side walls (15) that connect said front and rear walls (30, 31), and wherein said conveying cell (14) is open in an upward direction;
• for protecting each of said upwardly open conveying cells (14) from the surrounding atmosphere:
• a stationary and gas-tight top cover (17) that spans the open space of said upwardly open conveying cell (14), and stationary and gas-tight side covers (18) disposed on opposite sides of said conveying cell (14), wherein an interior space is formed in said conveying cell (14) by said top cover (17) and said side covers (18) for receiving a protective gas;
• and
• disposed in a bottom region of each of said conveying cells (14) that is located opposite said top cover (17):
• sealing elements (22, 34, 35) that protect intermediate spaces (32) existing between successive ones of said conveying cells (14) as viewed in the conveying direction from the surrounding atmosphere, as well as further sealing elements (22, 38) that on opposite sides extend laterally beyond said side walls (15) of said conveying cell (14), wherein said further sealing elements (22, 38) form respective sealing gaps (23) with a lower edge of said side covers (18).
