As shown, the livestock manure fermentation and malodor removing device according to the present invention is a storage tank (10) for storing the portion to nutrient solution ratio, and the nutrient solution ratio of the storage tank (10) by repeatedly suction, discharge to force circulation And a return pipe 20 for fermenting to an aerobic state, and a livestock manure fermentation and odor removing apparatus for releasing malodorous gas of the fermented nutrient liquor ratio into the atmosphere.

In particular, in order to ferment the livestock manure, the present invention includes a stirring means 30 which stirs and aerators the abundant liquid ratio by floating freely on the water surface while floating in the liquid ratio contained in the storage tank 10.

Condensate liquid ratio discharged from the barn is typically a high moisture content when stored in the storage tank 10, the organic matter is solidified and settles in the lower portion of the storage tank (10).

This solidified organic matter reduces the capacity of the storage tank 10, and reduces the efficiency of fermentation. Therefore, in order to be applied as a fertilizer in the nutrient solution ratio having both sides, it is necessary to increase the efficiency of fermentation, and to homogenize the liquid ratio located on the upper portion of the storage tank 10 by stirring the solidified organic matter.

The return pipe 20 circulates the nutrient solution ratio by repeating the operation of inhaling the nutrient solution ratio stored in the storage tank 10 and re-ejecting it, and serves to supply oxygen to the ejected nutrient solution ratio.

The return pipe 20 is composed of a suction pipe 22 and the discharge pipe 24, the suction pipe 22 and the discharge pipe 24 is connected to the suction pump 26 by the drive of the suction pump 26 The liquid fraction ratio is sucked in and discharged.

In addition, the ejection nozzle 29 is installed at the end of the discharge tube 24 for the above effect, the ejection nozzle 29 is formed in front of the nozzle port 29a through which the axial liquid fraction ratio passes at high speed. On the outer surface of the jet nozzle 29, a suction port 29b is formed.

The jet nozzle 29 applies the principle of the venturi tube, and the axial liquid-liquid ratio is passed through the nozzle port 29a at high speed by the suction force of the suction pump 26, and at the same time, the suction port 29b is discharged. Through the outside air is sucked at the speed of the axial liquid fraction passing through the high speed, and serves to supply oxygen to the axial liquid fraction finally ejected.

Return pipe 20 is to repeat the above process to supply oxygen to the nutrient solution ratio to agitate the nutrient solution ratio in aerobic state.

In addition, the present invention is to supply the oxygen to the condensate liquid ratio as described above to ferment under an aerobic state, agitate the condensate liquid ratio by the flexible hose 28, the stirring inside the storage tank 10 to further improve the stirring process It further comprises a means (30).

The stirring means 30 is a means for floating on the surface of the liquid storage liquid contained in the storage tank 10 to move freely on the water surface to stir and aeration the liquid liquid liquid ratio, and the float 32 floating on the surface of the liquid liquid liquid ratio, The electric motor 34 mounted on the float 32 and moved, and the return pipe 20 to a separate liquid-liquid supply pipe 36 are connected to the float 32 and extended below the water surface.

That is, the stirring means 30 is the supply pipe 36 branched from the discharge pipe 24 described above, after passing through the floating float 32 is extended below the water surface is supplied through the discharge pipe 24 It acts to agitate the liquid-liquid ratio by ejecting the liquid-liquid ratio and spraying and aeration of the organic substance solidifying under the water surface.

In addition, the float 32 and the supply pipe 36 are moved on the water surface by the electric motor 34 which can be selectively mounted to stir the axial liquid fraction in various places inside the storage tank 10.
