Overall processing apparatus of adulteration controlled by a density of suspended solids and smart adulteration processing method using thereof

摘要

The present invention relates to a comprehensive foreign material processor using a suspended solid concentration sensor and a smart foreign material processing method using the same. A filtrate discharged from manure and livestock waste to a filtrate storage tank through first foreign material separation by a rotary screen and foreign material dewatering by a screw press is distributed and supplied to a seed removal screen and a centrifuge connected to a cyclone to remove fine foreign materials such as seeds, animal hairs, and fine yarns. A waste component discharged from the seed removal screen is re-injected to the screw press to be dewatered together with the foreign material. Concentration sensors of suspended solids are each installed inside a flow adjusting tank and the filtrate storage tank at an inlet side of the rotary screen. The upper part of the rotary screen and the screw press is provided with a washing water spraying pipe, respectively, in which the washing water supply is controlled by the concentration sensor. The lower part of the cyclone is connected to a make-up water inlet pipe which is controlled to supply the make-up water by the concentration sensor. A drive motor of the centrifuge is an inverter motor of which rotation speed is controlled by the concentration sensor. If the concentration of the suspended solids in manure and livestock waste exceeds the set value, the washing water and the make-up water are pre-supplied at a proper location to lower the concentration of the suspended solids to a certain level. Accordingly, it is possible to prevent clogging of the rotary screen and seed removal screen and overload of the screw press and centrifuge such that the processing of the foreign materials is stably performed without interruption.
