Chicken manure fermentation system and chicken manure fermentation method

Abstract

The invention relates to a chicken manure fermentation system. The chicken manure fermentation system comprises a fermentation tank consisting of an inner tank body and an outer tank body, a stirringcomponent and a gas guiding component are arranged in the fermentation tank, a driving device with a stirring driving component is arranged above the fermentation tank, a heat insulation layer is sandwiched between the inner tank body and the outer tank body, heating components are arranged below the inner tank body symmetrically and are fixedly connected with the inner portion of the outer tank body, the stirring component comprises a stirring shaft and at least one disk stirring mechanism arranged along the axial direction of the stirring shaft, and the stirring shaft is connected with the driving device. The chicken manure fermentation system has the advantages that chicken manure and bubbles can be stirred and dispersed once through horizontal guide ports and interior stirring blades of stirrers and secondary stirring is achieved through rotation of the stirrers, so that stirring uniformity is improved substantially and fermentation efficiency is improved.

Description

technical field [0001] The invention relates to the field of chicken breeding, in particular to a chicken manure fermentation system and a fermentation method. Background technique [0002] With my country's reform and opening up and economic development, my country's animal husbandry has developed rapidly, greatly improving and enriching the "vegetable basket" of citizens and improving the living standards of the people. Untreated livestock and poultry excrement and waste water directly flow into rivers and lakes, causing a large amount of nitrogen and phosphorus loss, causing water pollution and eutrophication, and destroying the natural ecological environment; There is a lot of land, and a lot of odorous substances and nitrates will be produced during the stacking, which will pollute the atmosphere and groundwater. In rainy days, the sewage overflows, which often causes great dissatisfaction among nearby residents. Chicken manure is not timely during the chicken breeding ...
