A continuous aerobic composting device for dead livestock and poultry in livestock and poultry farms and its treatment method

Abstract

The invention discloses a continuous aerobic composting device and a disposal method for dead livestock and poultry on a livestock and poultry farm and belongs to the field of hazardous waste harmless utilization and recycling. The continuous aerobic composting device comprises a crushing device, a fermentation tank body and a main shaft driving device, wherein a feed opening is formed in the top of the fermentation tank body, a discharge opening is formed in the bottom of the fermentation tank body, and a bushing with leak holes is arranged at the inner lower part of the fermentation tank body; a main shaft is arranged in the fermentation tank body, and stirring blades are arranged on the main shaft; the lower end of the main shaft extends out of the bottom of the fermentation tank body and then is connected with the main shaft driving device; a feeding device is arranged on the outer side of the fermentation tank body; the crushing device is connected with the feed opening of the fermentation tank body by the feeding device. The continuous aerobic composting device can realize continuous automatic aerobic composting of dead livestock and poultry, is low in energy consumption and free of secondary pollution, realizes recycling of harmful wastes, is uniform in air distribution, avoids local oxygen deficit, and has the advantages of being low in cost, accurate in parameter control, sufficient in fermentation, high in degree of automation and the like.

Description

technical field [0001] The invention belongs to the field of harmless and resourceful utilization of hazardous waste, and relates to an aerobic composting system capable of continuous production, more specifically, to a continuous aerobic composting device for dead livestock and poultry in livestock and poultry farms and its treatment method. Background technique [0002] The harmless treatment of sick and dead livestock and poultry refers to the use of methods such as destruction, incineration, and biological treatment of sick and dead livestock and poultry and their products to make their infectivity and toxicity disappear. The harmless treatment of dead animals and their products involves not only social public health safety, but also the quality and safety of livestock products. For the treatment of sick and dead livestock and poultry, the traditional technology adopts deep pit burial, collective incineration and biological decomposition. Although it can kill germs, pre...

Problems solved by technology

However, the gas distribution in the tank of this reactor is uneven, the local hypoxia is serious, the material is not stirred sufficiently, and the material is not separated. It must wait for all the materials to be processed before they can be discharged. The processing cycle is long, the production cost is high, and the materials are manually added. , low degree of automation, no waste gas treatment function, the odor generated by the reactor seriously affects the air quality, not suitable for aerobic composting of dead livestock and poultry
