Embodiment Construction

[0043] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0044] Such as figure 1 As shown, the integrated food waste treatment machine of the present invention includes an anaerobic fermentation device and an aerobic composting device. The kitchen waste is pretreated to form a water-solid mixed slurry, and the anaerobic fermentation device converts the water-solid mixed slurry Perform anaerobic digestion and produce biogas, biogas slurry and biogas residue. The aerobic composting device is used to perform aerobic composting of the biogas residue. The anaerobic fermentation device includes an anaerobic tank 1, and the top of the anaerobic tank 1 is provided with a biogas collection Port 3, the aerobic composting device includes an aerobic tank 2 with an aerobic composting chamber...

Abstract

The invention provides a kitchen waste treatment all-in-one machine which belongs to the technical field of kitchen waste treatment, and solves the problems that an existing garbage treatment method wastes resources to certain extent, is not green and environmentally friendly, and has many defects in anaerobic composting and aerobic digestion. The kitchen waste treatment all-in-one machine comprises an anaerobic fermentation device and an aerobic composting device, wherein the anaerobic fermentation device comprises an aerobic tank, a biogas collecting hole is formed in the top of the aerobic tank; the aerobic composting device comprises an aerobic tank, a pit is formed in the top of the aerobic tank; the aerobic tank is arranged in the pit; an addition sandwich layer is formed between the inner wall of the pit and the anaerobic tank; the lower part of the addition sandwich layer communicates with an anaerobic digestion tank through a delay supply mechanism; the bottom of the anaerobic digestion cavity communicates with anaerobic composting cavity, and a communication portion is equipped with a biogas sag discharge mechanism. The kitchen waste treatment all-in-one machine has the advantages of integrating an aerobic digestion technology with an anaerobic composting technology, realizes continuous feeding and two-phase process of a single anaerobic tank through two-stage feeding, and can treat multiple kinds of garbage at the same time.

Description

technical field [0001] The invention belongs to the technical field of kitchen waste treatment and relates to an integrated kitchen waste treatment machine. Background technique [0002] The disposal of municipal solid waste is related to the sustainable development of our country, and has been paid more and more attention by people in recent years. As an important part of municipal solid waste, kitchen waste has high organic content and high recycling value. With the expansion of cities and the improvement of residents' living standards, a series of problems caused by food waste have become increasingly prominent. At the same time, the resourceful utilization and harmless treatment of kitchen waste has great market potential, and has received more and more attention from scholars at home and abroad. [0003] At present, domestic and foreign food waste treatment technologies can be divided into two categories: non-biological treatment and biological treatment technology ac...
