Stirring vane 4 on the adjacent stirring impeller 3 sets up in a staggered way, and the crisscross setting is that stirring vane 4's the work of turning over the shovel staggers, better stirs rubbish.

The screening aperture of the drum screen is 80 mm.

The device also comprises a water collecting tank, the water collecting tank is respectively connected with the crusher and the squeezer through a guide pipe, the organic matter concentration of the percolate after the crusher and the squeezer is high, the percolate enters the water collecting tank through the guide pipe to be effectively stored and finally treated,

still hold the storehouse including the fertilizer, the fertilizer holds the storehouse and connects fermentation storehouse bottom through the fertilizer contact tube, the fertilizer contact tube be equipped with channel switch, the fertilizer holds the thing in the storehouse and can be used for orchard, planting vegetables etc. becomes usable fertilizer with rubbish behind the wastes material kitchen, the fertilizer is favorable to improving the product quality. The organic fertilizer has comprehensive nutrients, contains various inorganic nutrients, various organic nutrients and a large amount of microorganisms and enzymes, and ensures comprehensive and balanced supply of nutrients required by fruit growth, so that the organic fertilizer has the effects of improving the quality of fruits and keeping the inherent nutrition and flavor of the fruits.

Oxygen sensor 5, humidity transducer 6, temperature sensor 7 and control panel 8 are installed to the fermentation storehouse, control panel 8 respectively with oxygen sensor 5, humidity transducer 6, temperature sensor 7, 2 control connection of roll axle.

Accessible control panel 8 sets up stirring impeller 3 stirring time and frequency, and the heater is installed all around to the microorganism fermentation storehouse, sets up length of heating, heating temperature isoparametric through control panel 8 for each regional temperature is unanimous basically in the fermentation storehouse, does benefit to the fermentation of material completely. The temperature sensor 7, the wetland sensor and the oxygen sensor 5 respectively measure the real-time temperature, humidity and oxygen amount in the fermentation chamber, and the real-time temperature, humidity and oxygen amount are displayed and operated on the control panel 8.

The control connection is a conventional technical means, so that only the function of the control connection is described here, and the specific structure is not described too much.

The drum screen, the ballistic screen, the crusher and the squeezer are all conventional structures, so that the functions are only described in a simple way and detailed structural description is omitted.

The fermentation chamber is provided with a ventilation opening 9, and the ventilation opening 9 is used for adjusting the oxygen amount in the fermentation chamber.

The working process is as follows: the kitchen waste enters a first bin of a pretreatment system through a chain conveyor: a drum screen. The large plastic and woven fabrics screened by the drum screen can be incinerated or buried. Manually sorting out interferents such as ceramic products, construction waste, metal and the like from oversize products of the drum screen, wherein the metal can be recycled; the undersize is ballistically screened to remove inert materials such as plastic bottles, stones, glass, etc., which are disposed of in landfills. After being screened, the garbage enters a crusher to crush larger garbage into small garbage, so that the later-stage squeezing and fermentation process is facilitated. The water content of the kitchen waste is as high as 80-90%, and in order to reduce the volume, the water content can be reduced to 30-50% through a squeezing dehydration process and fluctuates along with the fluctuation of the components of the waste. The leachate generated by the crusher and the squeezer has high organic matter concentration and enters the water collecting tank through the flow guide pipe to be stored and to be treated.

And finally, feeding the pretreated garbage into a microbial fermentation bin for fermentation. The microbial fermentation bin comprises a stirring impeller 3, stirring blades 4, a temperature sensor 7, a temperature controller, a heater, an oxygen sensor 5, a wetland sensor, a microbial inoculum inlet 1 and the like. The stirring impeller 3 in the fermentation chamber stirs at intervals, so that the microorganism is attached and distributed uniformly, and the decomposition and utilization are more thorough. The stirring time and frequency of the stirring impeller 3 can be set by the control panel 8. The heaters are arranged around the microbial fermentation bin, and parameters such as heating time, heating temperature and the like are set through the control panel 8, so that the temperature of each area in the fermentation bin is basically consistent, and complete fermentation of materials is facilitated. The temperature sensor 7, the wetland sensor and the oxygen sensor 5 respectively measure the real-time temperature, humidity and oxygen amount in the fermentation chamber, and the real-time temperature, humidity and oxygen amount are displayed and operated on the control panel 8. The ventilation opening 9 is used for adjusting the oxygen amount in the fermentation bin. One of the key factors in the process of forming the organic fertilizer in the microbial fermentation bin is the number and the variety of microorganisms in the bin, and the microorganisms can be added through the microbial inoculum inlet 1 to keep the activity of the microorganisms in the bin. The kitchen garbage has high organic matter concentration, and can be used as nutrient and attachment point of microorganism at proper temperatureUnder the environment of temperature, humidity and oxygen amount, organic matters can be rapidly decomposed into inorganic matters and self cell matters in the process of microbial proliferation and metabolism, and finally the organic fertilizer which has no secondary pollution and has popularization value is developed. The fermentation time of the microbial fermentation bin is 20-30 hours and fluctuates along with the working conditions and the change of garbage components. The fertilizer gets into the fertilizer from the contact tube after generating and holds the storehouse, can be used for orchard, planting vegetables etc. becomes usable fertilizer with wastes material kitchen garbage. The organic fertilizer is beneficial to improving the product quality. The organic fertilizer has comprehensive nutrients, contains various inorganic nutrients, various organic nutrients and a large amount of microorganisms and enzymes, and ensures comprehensive and balanced supply of nutrients required by fruit growth, so that the organic fertilizer has the effects of improving the quality of fruits and keeping the inherent nutrition and flavor of the fruits. The kitchen garbage disposal workshop inevitably has certain odor, and the main odor component is H₂S、NH₃And small amounts of organic gases such as methyl mercaptan, methyl amine, methyl sulfide, and the like. This integration refuse treatment device is equipped with deodorization system to keep the normal operating condition in processing workshop.
