Description

Garbage composting device

Technical Field

The invention belongs to the field of environmental protection engineering, and particularly relates to a garbage composting device.

Background

In recent years, the development of the environmental protection field, especially the guiding thought, in China gradually progresses from reduction to harmlessness to recycling. Under the guiding idea of resource utilization, the compost is used as a traditional solid garbage treatment process, and the importance of the compost is highlighted again. At present, the compost mainly takes organic garbage which is easy to degrade and harmless to the environment after degradation and is rich in N, P and other elements as raw materials.

Wherein the content of degradable organic matter components in the municipal solid waste is more than 56%, and the organic matter can be separated and aerobically composted. The organic matter source is mainly kitchen garbage and kitchen garbage. The kitchen waste has low salt content, good fertility when used as a composting raw material, relatively low invalid salt content, and is not easy to cause land salinization, so the kitchen waste is very suitable to be used as the composting raw material. The compost of livestock and poultry manure in rural garbage has a long history and is an excellent compost raw material. The aerobic composting is characterized by fast decomposition speed, short composting period and thorough degradation.

Chinese patent grant publication CN101983951B, grant publication date 2013, 05.01, discloses a device for composting in life, which comprises a box body, a feeding hole, a composting chamber in the box, an inward spiral stirring propeller, a bottom water bath, a heating device, a secondary composting chamber, a discharging hole and the like, and realizes 'quick aerobic fermentation of materials', and the occupied area is reduced by using the secondary composting chamber and shortening the longitudinal length of the device.

The CN101983951B equipment still has the problem that in order to limit the materials entering the decomposing stage (namely the secondary composting of CN 101983951B) every day, the number of stirring turns of the spiral stirring propeller is limited, and the materials entering from the feeding hole cannot be fully stirred, so that the stirring effect of the materials is poor, the oxygen content in the composting process is low, the scattering effect of effective strains is poor, and the leachate is too much. The landfill leachate can be used as a liquid fertilizer, but has the problems of large smell, high transportation requirement, high storage requirement and the like.
