Device for preparing organic liquid fertilizer by using restaurant kitchen garbage

Abstract

The invention discloses a device for preparing an organic liquid fertilizer by using restaurant kitchen garbage, which consists of an organic residue crushing separator, a treatment apparatus for further grinding the crushed organic residues, a bacteria tank for culturing microbial populations, an active agent tank and a fermentation tank. The discharge hole of the crushing separator is connected with the treatment apparatus, the discharge hole of the active agent tank is connected with the treatment apparatus and the bacteria tank, the fermentation tank can be divided into an overflow aeration stirring tank and an anoxic reaction tank, an aeration stirrer and the treatment apparatus form a first circulating loop, and the anoxic reaction tank and the bacteria tank form a second circulating loop. The crushing separator comprises a separator and a crusher; and after the domestic garbage enters the separator, the inclusions in the garbage are discharged through the separator, and the clean domestic garbage enters the crusher and is crushed into domestic garbage fragments. The practical crushing separator solves the problems of separation and crushing of the inclusions in the domestic restaurant kitchen garbage according to the actual garbage situation formed on the basis of domestic eating habits.

Description

technical field [0001] The present invention is a fertilizer manufacturing device that uses microorganisms to make organic residues such as food residues and sewage sludge into liquid fertilizers. Background technique [0002] So far, in order to increase the harvest rate of plants and prevent the occurrence of pests and diseases, excessive chemical fertilizers and pesticides have been put into the soil. This measure leads to the loss of useful microorganisms, the reduction of the insect repellent ability of the soil itself, the solidification of the soil and other phenomena. At the same time, it promotes the reproduction of useless microorganisms in the soil, resulting in an increase in the area of ​​soil that has lost its vitality. In order to improve the expansion of the above phenomenon, it is necessary to decompose the protein in organic waste such as kitchen waste by microorganisms to produce useful amino acids for soil improvement. [0003] However, in order to deco...
