Embodiment 1

[0019] Turn on the stirring device at the bottom of the municipal fermentable waste biogas digester to the forward rotation feed fermentation state, and continuously input the municipal fermentable waste powder into the biogas digester from the three-in-one port at the bottom for continuous fermentation.

Embodiment 2

[0021] Turn on the stirring device at the bottom of the urban fermentable waste biogas digester to the state of stirring and fermenting in forward rotation, and continuously stir and ferment the urban fermentable waste powder in forward rotation.

Embodiment 3

[0023] Turn on the stirring device at the bottom of the urban fermentable waste biogas digester to the state of reverse stirring and fermentation, and continuously reverse the stirring and fermentation of the urban fermentable waste powder.

Abstract

The invention relates to a refuse disposal device, in particular to a bottom feeding and discharging stirring device for an urban fermentable refuse biogas digester. The bottom feeding and discharging stirring device is characterized in that a feeding port, a discharging port and a stirring port of the urban fermentable refuse biogas digester are combined into one and formed in the bottom of the biogas digester, the bottom feeding and discharging stirring device is arranged to be an upright long propeller, the long propeller is arranged to rotate forwards and backwards, and the long propeller can be used for feeding fermentation or stirring fermentation of refuse powder when rotating forwards and can be used for stirring fermentation of the refuse powder or biogas manure discharging when rotating backwards.

Description

technical field [0001] The invention relates to a garbage treatment device, in particular to a stirring device for feeding and discharging materials at the bottom of a biogas digester for urban fermentable garbage, and belongs to the technical field of garbage treatment. Background technique [0002] Urban waste disposal has always been a problem in the world. Literature search shows that there are two traditional methods of urban waste disposal, one is landfill and the other is incineration. No matter which method is used, it will cause secondary pollution, that is, the air, water, soil, and rural areas will be polluted again after garbage disposal. This will permanently lengthen the pollution chain and is unsustainable. [0003] The literature search shows that the classification of municipal waste is a major technological progress, and the classified waste may become a new resource. Among them, the volume of urban fermentable waste is huge, which is not only the largest...
