Multi-layer fermentation device for livestock manure

Abstract

The invention discloses a multi-layer fermentation device for livestock manure. The multi-layer fermentation device comprises a heat preservation outer cover, wherein a plurality of layers of dewatering conveying belts are distributed in the heat preservation outer cover, each layer of dewatering conveying belt comprises a conveying belt assembly, each conveying belt assembly comprises an air outflow air pipe and a conveying belt, and a plurality of airflow back suction heads are further distributed on the inner side of each conveying belt; an air suction port is formed in the airflow back suction head; the plurality of air flow back suction heads are communicated with a main air suction pipe; and a buffer uniform spreading device is also distributed between two adjacent layers of dewatering conveyor belts. The device has the advantages that the fermentation effect is good, the quality is good, the fermentation period can be greatly shortened, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry manure treatment, in particular to a multi-layer fermentation device for poultry and poultry manure. Background technique [0002] After the livestock and poultry manure is dehydrated and dried, it is mixed with a certain proportion of yeast and then enters the fermentation device for aerobic fermentation. Currently, in order to save space, multiple layers are generally used, but in practical applications, the quality of fermentation of the same material by different devices The difference is very big, one is mainly the uniformity of the air circulation and ventilation system, the other is the temperature control problem, and the last very important problem is how to effectively control the dispersion of the falling material when the upper layer is passed to the lower layer. The traditional multi-layer After the materials are transferred between the layers of the fermentation device,...

[0002] After the livestock and poultry manure is dehydrated and dried, it is mixed with a certain proportion of yeast and then enters the fermentation device for aerobic fermentation. Currently, in order to save space, multiple layers are generally used, but in practical applications, the quality of fermentation of the same material by different devices The difference is very big, one is mainly the uniformity of the air circulation and ventilation system, the other is the temperature control problem, and the last very important problem is how to effectively control the dispersion of the falling material when the upper layer is passed to the lower layer. The traditional multi-layer After the materials are transferred between the layers of the fermentation device, because the poultry manure itself is very soft, once it falls to the lower layer, it will appear close to the lower conveyor belt and piled up and cannot be effectively dispersed, which is not conducive to the progress of aerobic fermentation; the above points together determine Fermentation quality of a poultry and livestock manure multi-layer fermentation plant
