Description
Technical field
The invention belongs to the field of organic solid castoff processing and resource technology, the aerobic fermentation that is applicable to the organic wastes such as changing food waste is processed and is disposed.
Background technology
Changing food waste is mainly derived from food process tankage (kitchen is remaining) and edible remaining (hogwash) that food and restaurant service industry, family and enterprises and institutions dining room etc. produce.Along with the develop rapidly of our national economy, the quickening gradually of Development of China's Urbanization, the output of changing food waste significantly rises in China, at home large-scale, in megapolis as Beijing, Shanghai, Shenzhen etc., the day output of changing food waste has reached thousands of tons of, and the annual production of national changing food waste reaches ten million ton.Along with the lasting propelling of Development of China's Urbanization, food safety and environmental safety more and more come into one's own, and changing food waste is used as traditional outlet of cultivation raw material just in atrophy.The processing disposal options of the changing food waste in current city is taking garbage loading embeading as main, changing food waste enters landfill yard except taking limited storage capacity, also can increase the load of follow-up percolation liquid treating system, in collection, transport and landfill disposal process, easily produce environment is produced to secondary pollution, can cause a hidden trouble to hygienic safety.As returnable put environment dirty and messy, multiply and attract the insects such as mosquito, fly, mouse, cockroach, infectivity disease, harm the people healthy; Near refuse collection transfer point, easily produce bad smell, cause the dislike on people's sense organ; Due to the higher characteristic of changing food waste water content, in the process of transport, easily there is changing food waste and leak outside and pour down or forth, have a strong impact on the appearance of the city, city's looks and traffic; Most importantly the rubbish of urban catering enterprise is many is collected by raiser, directly uses as feed ingredient, and the unprocessed human foods chain that enters of rubbish, jeopardizes the healthy of the people; And for away from the supporting food and beverage enterprise in natural scenic spots, urban, because of its shipment distance far the transhipment cycle long, its changing food waste producing is collected the temporary time than general food and beverage enterprise head at scenic spot, larger to the potential hazard of scenic spot environment.Changing food waste is the most general waste producing in daily life, belong to domestic refuse, its main component comprises the organism such as starch food, vegetable fibre, animal proteinum and fats, there is water ratio high, grease, salt content are high, perishable smelly, be unfavorable for the features such as common dumper transport.The environmental quality that the changing food waste producing for Special Areass such as Scenic Spots is very easy to superelevation to require in transport transfer process produces harm.The treatment technology of changing food waste mainly comprises landfill, burning, fodder processing, anaerobically fermenting and aerobic compost etc. at present, wherein more potential is anaerobically fermenting and aerobic compost, but these two kinds of method treatment cycles are longer, be difficult to meet changing food waste daily output day clear requirement.
The aerobic fermentation of changing food waste can be divided into ventilate biography oxygen and stirring biography oxygen, wherein stir biography oxygen and can be divided into again vertical mixing according to concrete alr mode difference, Horizontal stirring and drum-type stir three kinds, and only have Horizontal stirring biography oxygen and the drum-type that are applicable to changing food waste aerobic fermentation stir two kinds of biography oxygen, but the ratio that the current useful volume of existing changing food waste aerobic fermentation equipment on the market accounts for cubic capacity is all less than normal, the capacity utilization that is stirrer is seriously less than normal, in its stir chamber, the interpolation upper limit of material is generally only 1/5～1/4 left and right of cubic capacity, this has caused changing food waste aerobic fermentation equipment volume very huge, too fat to move, both caused equipment occupation space large, lifting difficulty, wasting again material makes cost high.Therefore,, under the background of this technology application, a kind of patent of invention of changing food waste aerobic fermentation equipment has been proposed.
Summary of the invention
The object of the invention is to develop a kind of changing food waste aerobic fermentation equipment.A kind of changing food waste aerobic fermentation equipment that the present invention proposes is by semi-cylindrical Horizontal stirring cavity, step-down gear, stirring shaft, stirring rake, stirring blade, device support shell and composition of the control system.This equipment lamps structure is simple, occupation of land face is little, volume is little, the feature of easy processing, intelligent operation, convenient management, is applicable to aerobic compost/fermentation stirring of application changing food waste/organic waste, is suitable for miniaturization, commercialization and regularization.
Rotation axis is installed in the stirring cavity of described a kind of changing food waste aerobic fermentation equipment, stirring rake is installed on rotation axis, can realize the material in cavity is carried out to reciprocating stirring oxygenation by the drive of step-down gear, on the addition of material, be limited to the following boundary line of stirring shaft, the capacity utilization that stirs cavity is greater than 90%.
The mode of operation of the stirring rake of described a kind of changing food waste aerobic fermentation equipment is clockwise and repeatedly replaces counterclockwise, when stirring rake turns near travel switch when rotation axis sea line approaches enclosing cover, shake-up being arranged on rotation axis sea line along clockwise direction, after being touched, travel switch will change the turning direction of step-down gear, it is rotated in the opposite direction with stirring rake, in the time that turning near the rotation axis sea line of opposite side, will touch equally stirring rake the nigh travel switch of installation, after being touched, travel switch will again change the turning direction of step-down gear, so move in circles.
The stirring rake of described a kind of changing food waste aerobic fermentation equipment should stagger when mounted mutually, and the projection angle of the deceleration machine side of adjacent two stirring rakes is 5 °～15 °.
The stirring blade of 3～7 row is installed on the length direction of the stirring rake of described a kind of changing food waste aerobic fermentation equipment, whipping device can be stirred fully fully loaded material in the process of work, on adjacent stirring rake, the projection of the locational stirring blade of same level at the bottom of stir chamber has intersection, the length that stirs blade is greater than the distance between adjacent two stirring rakes, utilize the angle between two adjacent stirring rakes and two stirring blades are staggered mutually, many rows long stirred blades and made whipping device abundant stirring without dead angle to material realization in operational process with the angle between two adjacent stirring rakes.
The end stirring blade of described a kind of changing food waste aerobic fermentation equipment clips a slice rubbery flexible sheet by two steel plates and forms, steel plate is 1～5cm with the spacing that stirs cavity inner wall, the edge of rubbery flexible sheet is close to the inwall that stirs cavity, rubber software can make whipping device in whipping process, encounter the hardness of matter such as relatively large bone still to stir smoothly, and be unlikely to occur the accident that " very stiff and demanding " or even stirring rake block, thereby ensure the operating safety of step-down gear and equipment.
The Controlling System control that the operation of described a kind of changing food waste aerobic fermentation equipment is made up of general electrical element; this composition of the control system is simple, reliable and stable; this Controlling System has the measure of the stoppage protection of uncapping, and can guarantee personnel safety in use.
