Description

Utilize device of lees discarded object production fertilizer Technical Field The utility model relates to the technical field of organic fertilizer production, in particular to a device for producing organic fertilizer by using distillers' grains waste. Background The distillers' grains waste is a main byproduct in the brewing process, is rich in organic matters, proteins, amino acids, trace elements and a small amount of alcohol, and can be prepared into an efficient organic fertilizer, so that the recycling of resources is realized, and the environmental pollution is reduced. Chinese patent document CN210176739U discloses a device for converting waste of vinasse into bio-organic fertilizer, which realizes the breaking of vinasse by a breaking roller driven by a high-speed motor, realizes the screening of the broken vinasse by a filter plate, accelerates the falling of the vinasse on the filter plate by the cooperation of a cam, a sliding plate and a spring, realizes the fermentation of the broken and screened vinasse by a fermentation box, facilitates the full fermentation of the vinasse, and ensures better quality of the organic fertilizer. However, in the process of sliding the filter plate up and down, the hollow cavity is communicated with the external environment, so that the vinasse splashes into the external environment from the hollow cavity, and pollution is caused.
