摘要

The device has an injecting tube (5) accommodated in a passage part (7), which is fixed at a container opening of a fluidized bed container. The passage part and the injecting tube are designed as a piston guide with sliding surfaces (8-11) extending in a passing direction. The injecting tube includes recesses (12, 13), which completely receive laterally aligned injection nozzles (3, 4). The passage part includes a shut-off unit (15) i.e. rotary disk valve, which is integrated in a passage opening (14). A sealing body (22) of the shut-off unit is connected with a hand lever (23).
