<p>Devices and methods for evenly distributing sludge, including manure and industrial sludge, to numerous hoses, over a large range of sludge suppl y pressures. Some devices include a housing having an inlet for receiving sludge under pressure and several outlets disposed outwardly through the housing cylindrical wall for coupling to hoses. The devices can include a rotating plate within the housing sweeping one or more baffles over the outlets to momentarily occlude the outlets and reduce flow through the occluded outlets. The baffles can include a first portion secured to the plate and a second portion removably secured to the first portion and/or the plate. Changing the total length of the baffles can change the affective cross-sectional area of the outlets available for flow at any instant in tim e. increased sludge supply pressure may call for installing smaller sized baffl es to reduce back pressure, while decreased sludge supply pressure may call for installing larger sized baffles to maintain sufficient back pressure to insu re even flow. Even manure distribution onto fields over different pressure rang es can be provided.</p> |
