Container of a Biogas System and Method for Removing a Component from the Container

A container of a biogas system, comprising a component (18) which may be removed from the container, for example an agitator (18) for mixing substrate (28) located in the container (10), a removal opening (30), as well as a removal device with which the component (18) may be removed at least partially through the removal opening (30) out of the container (10), for example for maintenance purposes, characterised in that

• the removal device comprises a flexible hose (34) which may be fastened with its first end to the removal opening (30), such that between the container interior and the hose interior a connection which is fluid-tight relative to the outside is present, through which the component (18) may be at least partially guided into the hose (34),
• the removal device comprises a closure device (36) by which the hose (34) may be closed in a fluid-tight manner in the state fastened to the removal opening (30), and
• the removal device comprises a constricting device (38) by which the hose (34) may be constricted by reducing the hose cross section in the state fastened to the removal opening (30), when a component (18) is inserted at least partially into the hose (34) in the region of its first end facing the container (10), so that when the hose is closed a space is produced in the hose interior which is fluid-tight relative to the surroundings and at least partially receives the component (18).
