The invention discloses a chemical co-production device of preparing an
organic fertilizer from
livestock and poultry manures, and belongs to the technical field of
organic fertilizer production equipment. The chemical co-production device comprises a homogenization
storage tank, a
solid-liquid separator, a groove type
fermentation tank, a ventilation
aeration element, a heat collection element, and a power supply. Through the ventilation
aeration element, manures will not enter an
aeration pipeline, the aeration pipeline will not be obstructed, the aeration process is guaranteed, and enough
oxygen is supplied to the
organic fertilizer to ensure the quality of the produced organic
fertilizer. By utilizing the ventilation aeration element, air flows out in a spiral form, the
wind power is increased, the air ejected in a spiral form is broken into a plurality of air bubbles, and the aeration efficiency is improved therefore. Through a deodorizing element, the
odor generated by the
fermentation in the groove type
fermentation tank is processed centrally; the manures are recycled and reused, the
energy consumption and
discharge are reduced, and the provided device has the advantages ofuniform aeration, high production efficiency, energy saving, and reduced emission, and is suitable for popularization.
