Aerobic fermentation device for kitchen garbage

Abstract

The invention discloses an aerobic fermentation device for kitchen garbage. The aerobic fermentation device comprises a fermentation tank which is arranged in a sealed mode, a material conveyor for supplying materials into the fermentation tank, a slide rod which is in sliding connection to the fermentation tank in the length direction of the fermentation tank, a drive mechanism used for driving the slide rod to slide in the length direction of the fermentation tank and a turnover throwing mechanism mounted on the slide rod for turning over and throwing materials; a net-shaped blind drain is formed in the bottom surface of the fermentation tank; an oxygen supply tube with oxygen supply holes for supplying oxygen is arranged in the blind drain; one end of the oxygen supply tube is equipped with a gas supply pump; and a gas exhaust tube used for exhausting gas communicates with the fermentation tank. Pulverized garbage is conveyed into the fermentation tank through the material conveyor, and oxygen is supplied into the fermentation tank through the oxygen supply tube, so that garbage is gradually subjected to aerobic fermentation, and is changed into organic substances. Odor generated by aerobic fermentation is less, so that pollution on environment is reduced. Odor only can be exhausted from the gas exhaust tube, so that odor is conveniently collected and treated in a concentrated mode.

Description

technical field [0001] The invention relates to kitchen waste treatment equipment, in particular to an aerobic fermentation device for kitchen waste. Background technique [0002] The output of kitchen waste in our country is large, and the random stacking and disposal of waste is easy to breed corruption and produce various pathogenic bacteria, which affects the appearance of the city and endangers people's health. Therefore, the treatment of kitchen waste has more important practical significance. [0003] Kitchen waste is a substance with high oil content, contains too much protein, cellulose, etc., and is easy to stink. Waste disposal generally adopts operations such as landfill, which is relatively defective. Therefore, it can effectively solve kitchen waste, and using kitchen waste composting is the best treatment method, which is very environmentally friendly. After composting, garbage can be turned into organic matter, which can be used for subsequent utilization, ...

AI Technical Summary

Problems solved by technology

[0004] At present, the traditional kitchen waste composting methods mainly include trough composting and strip composting: the trough composting method uses a fermentation tank to carry compost materials, and the fermentation process is generally completed in the workshop. more stench

The strip-stack composting method directly stacks materials into strip stacks with triangular or trapezoidal sections, which are usually stacked in the open air, but it occupies a large area, and the odor cannot be effectively controlled during the composting process, which is easy to cause air pollution, and the environment and climate are especially It is the precipitation process that has a greater impact on the effect of strip-stack composting
