Cellular wheel sluice for bulk material, and method for automatically clearing a cellular wheel of such a cellular wheel sluice

A cellular wheel sluice for bulk material comprising

• a. a housing with an interior,
• b. an extraction side cover detachably attached to the housing,
• c. a cellular wheel which is arranged in an operational position in the housing so that it can be driven in rotation about a longitudinal axis and which is held on the extraction side cover,
• d. an extraction device for displacing the cellular wheel between the operational position, in which the housing is closed and locked by the at least one extraction side cover, and an extracted position, in which the extraction side cover is unlocked and removed from the housing, wherein the extraction device comprises
• i. a guide unit for guided displacement of the cellular wheel along an extraction direction parallel to the longitudinal axis,
• ii. an extraction drive coupled to the extraction side cover for automatically driven displacement of the extraction side cover with the cellular wheel,
• wherein:
• e. the extraction drive is arranged fixed to the housing, and
• f. the cellular wheel sluice has a control unit, which is designed such that the cellular wheel is automatically displaceable between the operational position and the extracted position.
