Description
Technical Field
The invention relates to the technical field of fertilizer preparation, in particular to an integrated household kitchen waste composting device.
Background
The kitchen waste of China has large yield, wide production range and scattered production sources. It is estimated that the kitchen waste production in cities across the country exceeds 6000 million tons/year, accounting for about 37% -57% of the municipal domestic waste production, which percentage is 55% on average in developing countries. With the non-short promotion of national economic consumption level in China, the production amount of kitchen waste is further increased, the kitchen waste accounts for 40% of the production amount of urban solid waste, and how to realize the resource utilization of the kitchen waste is an urgent problem facing China.
The kitchen waste treatment equipment mainly refers to a related equipment machine or a processing and treating production line for processing, treating and converting a large amount of kitchen waste generated in social life, and is a large kitchen waste treatment production line or a small kitchen waste treatment equipment, so that the kitchen waste treatment and treating work can be better realized, the household waste generated in the society can be converted into resources available in other industries, and the social resources can be recycled. At present, the biological treatment technology of the kitchen waste in China mainly comprises two major technologies of aerobic composting and anaerobic fermentation.
The aerobic composting is an aerobic fermentation process driven by microbial communities, can decompose organic wastes into stable substances, and can promote safe and pollution-free recovery and utilization of nutrient resources by utilizing an aerobic composting technology to produce organic fertilizers. Due to the high organic matter content, comprehensive nutrient components and rich microorganisms of the kitchen wastes, the aerobic composting technology can effectively degrade the kitchen wastes. The kitchen waste treatment equipment can better and more quickly decompose or convert organic matters or other component substances contained in the kitchen waste into usable substance resources.
The pollution of the kitchen waste, the multiphase composition, the high moisture content and the low heat value of the kitchen waste determine that the resource utilization is very challenging. The current kitchen waste treatment mainly comprises two modes, namely centralized collection and transportation treatment and local distributed treatment, and most developed countries adopt a mode of combining the two modes for treatment. The rubbish that produces of daily life in the family is about 1 ~ 2kg, but the difficulty that the kitchen garbage classification brought is unfavorable for cultivateing the categorised consciousness form of rubbish, and brings the notion of self-control kitchen garbage compost into more families through the mode of promoting domestic compost equipment, simplifies its operation procedure, makes things convenient for people to use, just may encourage more people to go to practise the environmental protection theory.
Kitchen garbage compost equipment does not usually cover kitchen garbage preliminary treatment part, leads to the kitchen garbage granule great, and moisture is more, is unfavorable for the compost effect. The existing kitchen composting equipment is large equipment for centralized treatment and small community on-site treatment equipment, but the existing kitchen composting equipment is beautiful and practical integrated equipment suitable for household composting. Meanwhile, the kitchen waste devices have the problems of low composting efficiency, poor compost quality, complex manual operation and the like.
The state of the art domestic composting devices can be summarized as:
1. the equipment is complex, the operations such as stirring, aeration and the like need to be manually carried out, a large amount of labor time cost is wasted, the operation is inconvenient for operators to use, and the popularization of the household composting equipment is limited;
2. the kitchen waste is poor in fertilizing effect, an after-ripening area is not available, humus cannot be converted and accumulated to the maximum extent, and storage problems bring trouble to users if compost cannot be utilized timely;
3. mostly, single-bin fermentation, the materials with different decomposition degrees enter the composting process in the use process, the composting microbial community succession process is influenced, and then the composting process is slowed down, the composting quality cannot be guaranteed, and the requirements of harmless, reduced and recycled composting cannot be met.
