The device can classify the garbage into three categories, namely heavy objects, suspension categories and mixed impurity categories, by utilizing the step fall and the water flow scouring.

The working principle is as follows:

1. and starting a water injection pump, injecting the reclaimed water into the separation tank to reach the water level position, and then starting high-pressure water flow to realize automatic circulation of the reclaimed water in the separation tank.

2. The bag-breaking conveying belt and the two groups of rotary cutter wheels are started, after garbage is poured into the bag-breaking conveying belt, the garbage is pushed forward under the action of the conveyor, the garbage is pushed to the position below the first rotary cutter wheel averagely under the action of the material-homogenizing plate, the rotary cutter wheel rotating anticlockwise punctures a larger plastic garbage bag, the plastic bag is torn in rotation, and the purpose of separating the bag from the garbage is achieved. The smaller garbage bag can achieve the same effect as the first garbage bag after passing through the second rotary knife flywheel.

The separated plastic bags and the garbage continue to move forwards to the tail end of the bag breaking conveyor belt under the action of the conveyor belt, the tail end of the bag breaking conveyor belt is in seamless connection with a metal shoe sliding plate with an oblique angle of 50 degrees, and the garbage falls into the heavy object settling tank along the oblique sliding plate.

3. When rubbish gets into the heavy object and subsides the case, directly sink into the heavy object when rubbish weight is greater than the density of water and subside the incasement, the floater in the rubbish and suspended solid can cross the heavy object and subside the case and fall into the flotation separation incasement under the washing away of high-pressure rivers. The bottom of the floating separation box is a metal bushing which is inclined downwards by 10 degrees. The suspended stirring wheel in the separation pool is started, and light garbage and plastic garbage close to the water surface or in the water can be separated by repeatedly stirring in a counter-current mode and are sunk into the water bottom. The separation conveyor belt is started, the top end of the conveyor belt is slightly lower than the water level line, and when the separation conveyor belt rotates clockwise, the spike teeth on the separation conveyor belt can bring the suspended garbage still in the water into the water bottom.

After the garbage is accumulated in a certain amount, when the primary water seal flashboard is opened, the garbage smoothly slides into the material pushing bin under the action of water flow and the gradient of the inclined slideway, the primary water seal flashboard is closed, the water level is reduced, and the garbage is quickly filled under the action of water inflow from the water inlet pipe.

4. And (3) starting the floating stirring wheel, continuously pushing the plastic particle waste floating on the water surface to a floating collecting plate at the upper right part of the floating stirring wheel, and leading a concave outlet on the floating collecting plate into the conveying device. The plastic garbage collected at the stage can be recycled.

5. The lower part of the material pushing bin is a trapezoidal inclined sliding plate surface with the upper width of 2 meters and the lower width of 1.5 meters, the length of the waffle surface is about 0.9 meter, a secondary water seal flashboard is opened after a certain amount of garbage is accumulated at the position, and the garbage is discharged through a secondary discharge opening. After the garbage discharged from the secondary discharge opening falls into the cargo hopper, the secondary discharge opening is closed, and all garbage is separated. The garbage collected in the process is generally kitchen waste which can be crushed and can be buried or used for manufacturing organic fertilizer.

6. The drain hole on the goods fill with rubbish flows the moisture content in with rubbish, then pulls to rubbing crusher top position by the electricity on pulling the material loading platform, starts the hydraulic support pole of goods fill bottom, and when the goods fill plays to 70 degrees under the effect of hydraulic stem, the rubbish in the goods fill just pours into in the rubbing crusher feed inlet of lower extreme.

7. The pulverizer is a mature product in the mechanical market and does not need to be made by a user. After the grinder is started, the garbage is repeatedly ground, and the ground garbage is powder or fine particles.

To account for potential sterilization of the shredded wet waste. If the disinfection treatment is not carried out, the organic fertilizer is harmful to the people and the environment when being buried or manufactured. The crushed garbage can enter the high-pressure tank through the conveying belt, and the harmful germs in the garbage can be killed by utilizing the high-temperature steam provided by the heat source plant, so that the treated garbage can not cause harm to people, livestock and environment.

The treated garbage produces side product and has wide application. The garbage becomes single waste after being sorted, can be specially classified and sold to corresponding waste recycling operators, and can also form an industrial chain in a garbage disposal plant.

The wet garbage in kitchen and toilet after high temperature disinfection is naturally dried, and can be used for land reclamation, tree planting, flower planting, grass planting, desert covering and the like after being detected and identified by a soil expert.
