As shown in fig. 9 and 10, in order to more clearly express the working process of the above device, the present embodiment further provides a method for performing automatic kitchen waste crushing and composting by the above device, which includes the following steps:

1) First, a proper amount of kitchen waste is prepared, put into the pulverizing barrel 200, and the barrel cover 210 is closed. Furthermore, the first flushing device 300 is activated, adding a small amount of water for grinding. Secondly, drive arrangement 400 starts, and grinder 240 rotates and carries out the corase grind and the fine grinding to kitchen garbage, makes the granule diameter after the grinding accord with the compost requirement, improves compost efficiency.

2) The slurry of the garbage from the kitchen after grinding is delivered to the lower layer of the pulverizing barrel 200 through the through holes of the grinding plate 241 or the teeth of the grinding ring 242. The slurry makes circular motion under the stirring of the centrifugal disc 250 and settles and stratifies in the radial direction, the upper layer is swill with higher water content and enters the inner layer through the small holes on the centrifugal disc 250, and the lower layer is kitchen waste slurry with lower water content and continues circular motion under the stirring.

Further, the swill enters the inner layer, passes through the drainage port 510 of the drainage device 500, and is discharged to the main drainage port 2000 through the drainage pipe 520.

3) After the kitchen waste is ground and settled in the crushing barrel 200, the spherical valve 600 of the crushing barrel is opened, and the kitchen waste slurry in circular motion can rapidly pass through the connecting pipeline 700 in the tangential direction under the action of inertia and finally enters the composting barrel 1000. In addition, when the kitchen waste slurry passes through the connecting pipeline 700, the EM bacteria solution is taken out from the EM bacteria barrel 800 due to the pressure difference caused by the flow velocity, the mixture is uniform, and the volume ratio of the EM bacteria solution and the mixture meets the maximum efficiency of composting to the maximum extent. Kitchen waste slurry can enter the main barrel body 1020 of the compost barrel 1000 from the tangential direction, and the motion track of the slurry can be downward along the rotating parabola of the barrel wall, so that the loss of kinetic energy is reduced, the slurry in the compost barrel 1000 is stirred by the kinetic energy, and meanwhile, splashing and noise caused by directly falling the water surface of the slurry are also reduced.

4) After all the kitchen waste slurry in the crushing barrel 200 enters the composting barrel 1000, the spherical valve 600 of the crushing barrel and the driving device 400 are closed, so that the tightness of the crushing barrel 200 is ensured. Then the electric heating device 1100, the air extraction device 1200 and the aeration device 1300 are started to control the environmental variables in the compost bucket 1000 so as to provide the most suitable fermentation environment to the maximum extent. The electric heating device 1100, in cooperation with the sensor 1700 of the main tank 1020, dynamically provides heat according to the real-time temperature, and the aeration device 1300 is used for dissipating heat and cooling the slurry after being started. The air extractor 1200 extracts air from the top of the main barrel 1020 to form a negative pressure area at the top of the main barrel 1020, the aerator 1300 blows air into the lower barrel 1030 through the air blowing pump 1320, and the pressure difference between the high pressure area of the lower barrel 1030 and the negative pressure area at the top of the main barrel 1020, which is formed during air blowing, is greater than the pressure at the bottom of liquid, so that the requirement of continuous stable aeration of slurry with the maximum volume is met. When the air extractor 1200 discharges air, the air firstly passes through the photocatalytic device 1210 to purify waste gas, and then is discharged into the atmosphere, so that the environment is protected.

5) The fermentation stage and the leaching stage are alternately carried out. When the draining stage is performed, the aeration device 1300 stops working, the air exhaust device 1200 continues to operate, and the gas exchange device 1400 is started to balance the air pressure of the main barrel 1020 and the lower barrel 1030, so that liquid fertilizer in the kitchen waste slurry is naturally filtered out under the action of gravity. Further, when the gas exchange valve 1420 of the gas exchange device is opened, the high pressure area of the lower tub 1030 is released, and the internal gas pressure of the lower tub 1030 and the main tub 1020 is balanced. After draining, the generated liquid fertilizer drops through a small hole at the bottom of the main barrel 1020 and is collected and stored by the lower barrel 1030, and the generated kitchen waste residue is temporarily stored in the compost barrel 1000, continues to ferment and is finally discharged to a main sewer pipeline through the second flushing device 1600.

6) After the liquid fertilizer after draining is accumulated on the lower barrel 1030, one end of an output pipeline 1810 of the liquid fertilizer output device 1800 is immersed, so that the liquid fertilizer can be conveyed at any time. After the liquid fertilizer output device 1800 detects that the liquid fertilizer water level meets the output standard by the lower barrel sensor 1720 and receives a liquid fertilizer output instruction, the output valve 1820 and the water inlet valve 1840 are opened, one end of the water inlet pipeline 1830 receives water flow from the main water inlet 1900, when the liquid fertilizer passes through the interface of the output pipeline 1810, the liquid fertilizer is taken out from the lower barrel 1030 due to pressure difference caused by flow velocity and is uniformly mixed, the volume ratio of the liquid fertilizer to the water inlet pipeline 1830 meets the fertilizing requirement and is conveyed to the other end of the water inlet pipeline 1830, and the liquid fertilizer and water are mixed, diluted and transported.

7) The kitchen waste smashing device I and the kitchen waste composting device III can self-clean the interior through the first flushing device 300 and the second flushing device 1600, the drainage device 500 and the pollution discharge device 1500 which respectively correspond to the kitchen waste smashing device I and the kitchen waste composting device III, and the air exhaust device 1200 in the composting barrel 1000 can complete the subsequent dehumidifying and drying of the device. Specifically, a ball valve 600 of a crushing barrel of the kitchen waste crushing device I is opened, and a valve of a main barrel 1020 and a valve 1520 of a lower barrel of the kitchen waste composting device III are opened; then, the first flushing device 300 of the kitchen waste crushing device I is started, the water flow washes the inner wall and the bottom surface of the crushing barrel 200, and the grinding device 240 can rotate at a low speed, so that the washing efficiency is improved; furthermore, a part of the water flow after washing enters the main water outlet 2000 through the water discharge device 500 of the kitchen waste smashing device I, the other part of the water flow enters the main water outlet 2000 through the connecting pipeline 700 to clean the inner wall, at the moment, the flow velocity of the water flow is far lower than the moving velocity of the normally smashed kitchen waste slurry, the threshold value of the check valve of the output pipeline 1810 of the EM bacteria barrel 800 is not triggered, namely, EM bacteria solution is not mixed or is rarely mixed, and EM bacteria waste is caused, meanwhile, the second water flushing device 1600 of the kitchen waste composting device III is started, the water flow washes the inner walls and the bottoms of the main barrel 1020 and the lower barrel 1030, an axial vortex is formed in the barrel to flush the internal kitchen waste residues into the main water outlet 2000 along with the trend, liquid fertilizers remained in the lower barrel 1030 are also flushed into the main water outlet 2000, the diameter of the opening part of the valve of the main barrel 1020 meets the requirement of no blockage during washing, the water drainage efficiency is high, finally, after the internal garbage residues are washed clean, the first water flushing device 300I of the kitchen waste smashing device and the second water flushing device 1600 of the kitchen waste smashing device III are closed, the spherical kitchen waste gas valve 600 of the kitchen waste composting device 600 is closed, the self-cleaning device 1400, and the self-drying device 1200 is completed.

3) The spherical valve (600) of the crushing barrel is opened, and kitchen waste slurry which does circular motion quickly passes through the connecting pipeline (700) along the tangential direction under the action of inertia and finally enters the composting barrel (1000); when the kitchen waste slurry passes through the connecting pipeline (700), the EM bacteria solution is taken out from the EM bacteria barrel (800) due to the pressure difference caused by the flow velocity, and the EM bacteria solution are uniformly mixed;

4) After all kitchen waste slurry in the crushing barrel (200) enters the composting barrel (1000), closing the spherical valve (600) of the crushing barrel and the driving device (400); then, starting the electric heating device (1100), the air exhaust device (1200) and the aeration device (1300), controlling the environmental variables in the compost barrel (1000) and providing a fermentation environment for fermentation;

5) A liquid leaching stage; when the draining stage is carried out, the aeration device (1300) stops working, the air exhaust device (1200) continues to operate, and the gas exchange device (1400) is started at the same time and is used for balancing the air pressure of the main barrel body (1020) and the lower barrel body (1030) so that liquid fertilizer in the kitchen waste slurry is naturally filtered under the action of gravity and collected and stored by the lower barrel body (1030);

6) Liquid manure after draining is piled up in lower barrel (1030), and liquid manure output device (1800) receives rivers from the outside after sensor (1700) detects that liquid manure water level reaches output height and receives liquid manure output instruction, takes out liquid manure from lower barrel (1030) because the pressure difference that the velocity of flow caused, and this process is accomplished liquid manure and the mixed dilution of water and is transported.
