Integrated household kitchen waste composting equipment

Abstract

The invention discloses integrated household kitchen waste composting equipment which comprises a feeding and crushing device; a squeezing device; a feeding channel on which a strain inoculation portis formed; and a biochemical system, wherein kitchen waste enters the biochemical system sequentially through the feeding and smashing device, the squeezing device and the feeding channel, and a microbial inoculum enters the biochemical system through the feeding channel; the biochemical system comprises a biochemical bin and a post-decomposition bin; the biochemical bin is axially divided into aplurality of bin bodies, every two adjacent bin bodies are separated through a partition plate, holes are formed in the partition plates, the last bin body is a discharging bin, the other bin bodies are fermentation bins, a feeding port is formed in the first fermentation bin and communicated with the feeding channel, and a discharging port is formed in the discharging bin and communicated with the rear decomposing bin. The biochemical bin is provided with an aeration device, a stirring device and a heating device. According to the equipment, the kitchen waste is treated by adopting bin separation type fermentation so that the operation process is simplified, the labor and time costs are reduced, the fertilizer is rapidly formed, and secondary pollution is avoided while the recycling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizer preparation, in particular to an integrated household kitchen waste composting device. Background technique [0002] China has a large output of food waste, a wide range of sources, and scattered sources. It is estimated that the amount of food waste generated in cities across the country exceeds 60 million tons per year, accounting for about 37%-57% of the amount of municipal solid waste generated, and this percentage is 55% on average in developing countries. With the continuous improvement of the consumption level of the national economy in our country, the production of kitchen waste will further increase, and kitchen waste has accounted for 40% of the urban solid waste. urgent problems facing. [0003] Food waste treatment equipment mainly refers to related equipment or processing lines for processing and transforming a large amount of food waste generated in social life, whether it is a...

AI Technical Summary

Problems solved by technology

[0008] 1. The equipment is complex and requires manual operations such as stirring and aeration, which wastes a lot of labor time and cost, is not convenient for operators to use, and limits the promotion of household composting equipment;

[0009] 2. The fertilizer effect of food waste is poor, there is no post-ripening area, the humus cannot be transformed and accumulated to the greatest extent, and if the compost cannot be used in time, the storage problem will bring troubles to users;

[0010] 3. Most of them are fermented in a single warehouse. During the use process, materials with different degrees of decomposition will enter the composting process, which will affect the succession process of the composting microbial community and cause the composting process to slow down, and the quality of the composting cannot be guaranteed, and it cannot achieve harmlessness and reduce waste.
