<p>An apparatus for selectively collecting silage effluent draining from a silo at a variable flow rate comprises a delivery conduit [12] extending at a small upward angle into a housing [14] set into the ground. The housing contains two collecting vessels in the form of mutually parallel drainage channels [15, 16]. In dry weather conditions the flow rate of silage effluent exiting from the outlet [13] of the conduit is at a low level. In such conditions the effluent has insufficient velocity to detach itself from the outlet [13] and runs back under the conduit [12] to drop off into the rear channel [15]. In conditions of wet weather, however, the silage effluent is diluted with rainwater and exits from the outlet [13] at sufficient velocity to fall into the front channel [16]. The rear channel [15] is connected via a pipe [17] to a slurry tank, whereas the front channel [16] is connected via a pipe [18] to any suitable drainage system.</p> |
