The wet garbage is generated in activities such as daily life and food processing, food service, unit catering and the like of residents, and comprises abandoned vegetable leaves, leftovers, fruit peels, eggshells, tea leaves, bones, animal viscera, fish scales, leaves, weeds and the like, and the main sources of the wet garbage are family kitchens, restaurants, dining halls, markets and other industries related to food processing.

The wet garbage contains extremely high moisture and organic matters, and is easy to rot to generate stink. After proper treatment and processing, the biomass can be converted into new resources, the characteristics of high organic matter content enable the biomass to be used as fertilizer and feed after strict treatment, methane can be generated to be used as fuel or power generation, and the grease part can be used for preparing biofuel.

For the treatment of wet garbage, for example, a kitchen garbage treatment device disclosed in application No. 201810470151.1 is used for treating and utilizing household garbage by lifting and dumping equipment, conveying and crushing equipment, oil and salt removing equipment, crushing equipment, solid-liquid separation equipment, fermentation equipment and the like.

However, the overall structure of the device is complex, the occupied space is large, and the following problems are also existed:

(1) the oil and salt removing device 3 comprises a roller 31, the inner wall of the roller 31 is provided with a spiral blade 311, the spiral blade 311 is arranged on the inner wall of the roller 31, so to realize the rotation of the spiral blade, the roller needs to rotate integrally to drive the spiral blade to rotate, but a spraying device 33 extends into the roller 31 from the outside of the roller 31, so that the spraying device needs to rotate along with the roller 31 obviously, if the spraying device 31 rotates, the difficulty of supplying water for the spraying device is obviously increased, and the design is obviously unreasonable here.

(2) The wall of the drum 31 of the oil and salt removing equipment is of a screen structure, which can increase the drainage area in principle, but because wet garbage contains many sticky substances, such as dough, rice grains and the like, the screen holes are easily blocked, so that the problem of blocking of the screen holes is further increased by the large-area screen holes, and the drainage efficiency is influenced; and because the cylinder wall is of a screen structure, the discharged liquid needs to be collected by the liquid accumulating box, and the size of the liquid accumulating box at least needs to extend from one end to the other end of the roller 31 and cover the whole circumferential surface of the roller 31 as much as possible, so that the size of the liquid accumulating box is greatly increased.

(3) The crushing equipment and the solid-liquid separation equipment are realized by two sets of equipment, the structure is relatively complex, and the number of power sources is increased.

(4) The solid-liquid separation equipment is longitudinally arranged, a feed inlet is downward, a discharge outlet is upward, the garbage is conveyed upwards by using a spiral propeller, and the garbage falls under the action of self gravity in the propelling process, so that the upward conveying efficiency is reduced; in addition, during the conveying process, a large amount of liquid is bound to be accumulated at the inlet 511 under the action of gravity and cannot be discharged, and even if the liquid in the garbage is extruded out, a large amount of water is not discharged from the screen wall 512 and is accumulated, so that the liquid cannot be effectively collected and discharged.

s1, pouring the wet garbage into a material groove; specifically, hang the garbage bin and locate on the garbage bin emptys mechanism 5, the last weighing sensor of garbage emptys the mechanism 5 acquires the weight of garbage bin and gives controlling means with data transmission, and controlling means signals simultaneously and gives upset motor or upset cylinder 52 start-up make upset arm 51 rotates the garbage bin and overturns to the state of opening downward sloping, and wet rubbish in it enters into in the material groove 11.

At this moment, the motor 82 of the garbage bin cleaning mechanism 8 starts to drive the movable nut to stretch the spray head into the garbage bin and open the water source pipeline to spray water to the inner wall of the garbage bin to realize cleaning, and the motor 82 rotates reversely while cleaning, so that the spray head slowly withdraws from the garbage bin, thereby effectively realizing the coverage cleaning of the inner wall of the garbage bin, and certainly, in other embodiments, the spray head can also be cleaned repeatedly in the garbage bin. Meanwhile, the cleaned sewage falls into the material tank to carry out primary washing on the wet garbage in the tank. After cleaning, the motor 82 drives the spray head to reset, and the overturning motor or the overturning cylinder 82 drives the overturning arm to enable the garbage can to return to the initial position.

And S2, connecting the cleaning device 2 with a water source for supplying water, so that the cleaning device 2 washes the materials in the material tank, and discharging the washed oil-water mixture out of the material tank from the liquid discharge hole and entering the oil-water separator 6 for oil-water separation.

S3, the motor 16 is started to drive the spiral conveying shaft 15 to start to convey the cleaned garbage to the discharging end, in the conveying process, liquid in the garbage is collected towards the direction of the liquid discharging hole under the action of gravity, so that oil and water in the wet garbage are further removed, the wet garbage is conveyed to the crusher by the spiral conveying shaft 15, and before the wet garbage enters the crusher, the zymophyte supply device of the zymophyte spraying device 9 is started to add zymophyte into the wet garbage through the nozzle.

The wet garbage entering the crusher moves towards the bottom of the barrel under the conveying of the spiral conveying shaft 32, the wet garbage is crushed under the combined action of the extrusion force of the spiral conveyor, the shearing force between the spiral blades 321 and the cutting strips 36 and the cutting force of the crushing cutters, and a liquid part generated in the crushing process is extruded out of the filter sleeve 35 and is discharged to the buffer tank I10 from the liquid outlet end of the bottom of the barrel 31; meanwhile, materials which cannot pass through the filter sleeve 35 move to the outlet end of the bottom of the barrel 31 under the extrusion force of the spiral conveying shaft 32, and are discharged to the second buffer tank 20 after the floating plug is extruded;

and S4, the crushed liquid and solid in the first buffer tank 10 and the second buffer tank 20 enter the drying chamber to be dried and quantitatively discharged under the action of the pressure of the subsequent materials and/or the suction force of the pump and/or the suction force of the drying chamber.

Specifically, the vacuumizing device starts to vacuumize the drying chamber 42 to a set vacuum degree, the electric heating film starts to heat to a set temperature, the two electric valves 41 are opened, the materials in the first buffer tank 10 and the second buffer tank 20 are injected into the drying chamber 42 through the pressure of the materials which continuously enter subsequently and/or the suction force of the pump under the negative pressure side effect in the drying chamber 42, the motor 44 starts to drive the spiral conveying shaft 43 to move the materials forwards and backwards in the drying chamber, thereby controlling the staying time of the materials in the drying chamber, fermenting and drying the materials in the drying chamber, when the set staying time is reached, the screw conveying shaft 43 extrudes the material from the discharge port 423 to the quantitative blanking bin 50, when the weight of the material in the quantitative blanking bin 50 reaches a set value, the material is stopped being squeezed into the quantitative blanking bin 50, and at the moment, the push-pull device 506 starts to open the bottom plate 501 to achieve blanking.

The utility model has a plurality of implementation modes, and all technical schemes formed by adopting equivalent transformation or equivalent transformation all fall within the protection scope of the utility model.
