Biogas plants - feed pump for conveying to say non-pumpable, biomass in a biogas plant

摘要

Biogas plants - feed pump (1) for conveying to say non-pumpable, biomass (41) in connection with a fermentation process a biogas installation (2) for the generation of biogas, wherein the feed pump (1) outside of a fermenter container (4) of the biogas plant (2) is set up in the dry state, with a toroidal pump housing (6),with a coaxially with respect to the pump housing (6) lying pump impeller (7) to an inner impeller part in the pump housing (6) is received,with a forming the pump inlet aperture at the rotor (9) of the pump housing (6), wherein the biomass (41) in the case of a impeller rotation in the aperture at the rotor (9) of the pump housing (6) is pulled,with an approximately tangential outlet (10) on the toroidal pump housing (6), andwith a drivable pump shaft (20), the to the pump impeller wheel (7) is connected,characterized by the,that the aperture at the rotor (9) of the pump housing (6) in the functional position of the feed pump (1) has an upwardly,that the toroidal pump housing (6) on the side of the aperture at the rotor (9) with an intake shaft (13) is provided, the..
