Background technology
Along with socio-economic development, urbanization process are accelerated, living standard improves, the kitchen castoff generation grows with each passing day, and surpasses the self-purification capacity of the earth, becomes worldwide public hazards: 1, transmission, gene mutation.Because the vertebrate gene order is similar, canteen easily causes the propagation of the zoonosis such as rabid ox disease, aftosa, bird flu, SARS mutually, and gene mutation, offspring's developmental deformity of homologous genes pollution initiation, easily brings out canceration; 2, the wasting of resources.Approximately 6,000 ten thousand tons of the annual kitchen castoff output of China, be equivalent to approximately 100,000,000 mu of arable land annual capacities, 1 annual production, grain ration of a year of people more than 200,000,000 that medium province the whole province ploughs, through investigation, coastal prefecture-level city Weihai of 2800000 populations, more than 30 ten thousand tons of the annual kitchen castoffs produced, approximately be equivalent to the annual production of whole arable lands, more than the 70 ten thousand people grain ration of a year in more than 50 ten thousand mu of arable land annual capacities, tens towns; 3, " waste oil " returns to dining table.Serious threat food security, the harm people's health, affect social stability; 4, soil compaction.The high fat of the high salt of kitchen castoff, as fertilizer sources is used and easily causes soil compaction, and contaminated land and vegetation reduce grain yield; 5, environmental pollution.Together with house refuse, burn, landfill causes environmental pollution
;zha, natural pond, the natural pond liquid that produces natural pond generating generation also can cause secondary pollution.
2000, the World Health Organization explicitly pointed out, and kitchen castoff and handled thing thereof are forbidden using as animal (vertebrate) feed and organic fertilizer.2008, Japan formulated " recycling economy method ", forbids that kitchen castoff and handled thing thereof are used as animal (vertebrate) feed.At present, Japan is most adopts the appearance bacterium that disappears to clear up the decrement method, just kitchen castoff is carried out to harmless treatment, not complete resource utilization.Kitchen castoff harmless treatment, recycling, become global problem.Therefore; National Development and Reform Committees in 2010 propose to implement in full before 2015 the policy of kitchen castoff harmless treatment, recycling; how from changing food waste, efficient separation and Extraction profit and environmental protection, recycling treatment remain solid-state changing food waste; at present, remain a problem that allows city manager and destructor plant headache.
In prior art, the device that adopts the biofermentation groove to carry out disposal of refuse is arranged, it arranges shaft fermentation tank upper end and is provided with charging aperture in fermentation tank, bottom one side is provided with the raw material outlet, the fermentation tank bottom is provided with the oxygenation gap along the shaft axis direction, air enters from the raw material outlet of tank diameter, from charging aperture, discharge, shaft is provided with helical blade, be beneficial to for puddling rubbish, its deficiency is: unreasonable structure, make loaded down with trivial details, the one, the oxygenation gap is located at the tank diameter bottom, easily make feed blocking, cause the oxygenation insufficient fermentation, the 2nd, the tank diameter temperature is wayward, fermentation time is unfixing, cause fermenting insufficient, treatment effeciency is extremely slow.
Through retrieval, CN2730508A discloses a kind of rubbish sterilizing, the utility model patent of fermentation processing unit, it comprises process tank, the feeding device of a phase process tank feed and a heater that supplies to the process tank heat supply, feeding device is connected with the process tank charging aperture, this processing pipe has the charging aperture that is positioned at top and the discharging opening that is positioned at bottom, laterally be provided with at least two agitators along described process tank, this processing inner tube layer has conduction oil interlayer, for heater, with conduction oil interlayer, be communicated with and the process tank connection, although it has solved the problem of the homogeneous heating of fermentation tank, but deficiency is complex structure, mode of heating is loaded down with trivial details, can not directly to described changing food waste, carry out drying processes, in the oxygenation sweat, need to be equipped with air hot pipe and inflate fermentation in process tank, cause processing speed slow, ferment effect is undesirable, and, in the process of feeding intake, need to manually be fed intake, cause workman's health of human body can not be guaranteed.
