The invention relates to a
compost reactor for quickly, efficiently and harmlessly treating
livestock manure, comprising a cylindrical fermenter which is divided into an upper
fermentation chamber anda lower equipment chamber, wherein a feed port and a gas outlet are formed in the top of the
fermentation chamber, a
discharge port and a
discharge valve are formed in the side face of the
fermentation chamber, a heating coil tube surrounding the inner wall of the fermentation chamber is arranged on the inner wall, a liquid inlet end and a liquid outlet end of the coil tube are connected to a high temperature circulating
oil bath tank located in an equipment chamber, three stirring motors and
air pump are arranged in the equipment chamber, the three stirring motors drive three stirring rods to rotate, the three stirring rods are distributed in an equilateral triangle, each stirring rod is provided with a plurality of
layers of stirring blades, three stirring blades are arranged on each layer, an angle of 120 degrees is formed between the stirring blades of the same layer, the stirring blade
layers of the three stirring rods are distributed in a staggered manner, the stirring rods andthe stirring blades both are of hollow structures and communicated with each other, and an air outlet of the
air pump is communicated to the bottoms of the three stirring rods by the air outlet, and aplurality of air outlet holes are formed in the stirring blades.
