A REGULATORY FRAMEWORK USING AUTOMATIC CERTIFICATION SYSTEM FOR SOFTWARE DEFINED RADIO

A manure separating apparatus includes a trough with angularly bottom surfaces that converge downwardly to a discharge opening. A drain screen is located above the bottom trough surfaces and includes somewhat similarly angled downward converging infeed and discharge surfaces. The infeed section of the drain screen is approximately twice as long and at a smaller angle to the horizontal than the discharge screen section. A manure/liquid slurry may be introduced at a top infeed end of the screen and moved downwardly along the infeed section of the screen by a paddle conveyor. Separation of solids occurs primarily along the infeed screen section. The slurry is then moved angularly upwardly along the discharge section of the screen for final dewatering. The discharge section is spaced above the trough bottom to avoid liquids on the trough bottom below to facilitate dewatering of the solids before discharge. Movement is influenced by the paddle conveyor which has a working flight powered to move and scrape along the drain screen sections from the infeed end of the trough from its discharge end. In combining prescribed infeed and discharge sections of the screen in a single trough with operation of the paddle conveyor, a high degree of separation and dewatering efficiency is obtained without requiring a significant dimension along the path of travel for the slurry.
