Kitchen waste treatment and composting system

Abstract

The invention discloses a kitchen waste treatment and composting system. The system comprises a front treatment box, wherein a moving automatic feed mechanism is installed at one side of the front treatment box; a crushing cutter rotating disk is installed at the bottom in the front treatment box and is connected with a crushing motor; a squeezing disk is installed on the top in the front treatment box and is connected with an electric push rod and with an oil-water separation mechanism below the front treatment box by a pipeline; a discharge hole and a screw conveying mechanism are formed in the bottom of the front treatment box; the screw conveying mechanism is also connected with a feeding hole of a degradation reactor; the degradation reactor adopts a double-layer metal plate box; an electric tracing band is wound around the outer wall of the inner cavity of the box; a stirring motor is installed at the bottom of the degradation reactor and is connected with a stirring and sweeping cutter arranged inside the degradation reactor; a vacuum dehumidification mechanism and a water mist deodorization mechanism are arranged on the top of the degradation reactor; a fertilizer outlet in the bottom of the degradation reactor is connected with a finished fertilizer collecting mechanism. The system has the advantages that the kitchen wastes are decomposed and fermented by utilizing microorganisms; the products can serve as high-quality fertilizers.

Description

technical field [0001] The invention relates to the field of kitchen waste treatment, in particular to an efficient and environment-friendly kitchen waste treatment fertilizer making system. Background technique [0002] Kitchen waste, commonly known as swill, is the domestic waste formed by residents in the process of living consumption. The main components include rice and flour food residues, vegetables, animal and vegetable oils, meat and bones, etc. From the chemical composition, there are starch, cellulose, Proteins, lipids and inorganic salts. Its main features are rich in organic matter, high in water content, and perishable. Its properties and odor will have a bad impact on environmental sanitation, and it is easy to breed harmful substances such as pathogenic microorganisms and mycotoxins, threatening human health. At present, the traditional kitchen waste There are two main methods of disposal: incineration and landfill. Incineration treatment is easy to produce...

AI Technical Summary

Problems solved by technology

Incineration treatment is easy to produce harmful gases, and the high moisture content leads to low calorific value of kitchen waste, which is easy to cause damage to incineration equipment; and landfill method is easy to cause soil and groundwater pollution

If kitchen waste with high water content and high salinity is directly mixed with other garbage for landfill, under the action of high pressure and microorganisms, a permeate that is not easy to degrade and contains highly toxic carcinogens will be formed. Once the permeate leaks out, it will cause The secondary pollution of the environment seriously threatens the health and safety of the people

[0003] According to the traditional kitchen waste treatment method, a lot of reusable resources will be wasted. Food waste contains a lot of nutrients, the main components are oil and protein, which can be processed into high-energy protein and high-quality feed instead of corn, fish meal, soybean meal, etc. It is also a suitable raw material for the production of biodiesel
