Wherein, kitchen garbage just belongs to one kind of domestic waste, and at present, through the investigation domestic current kitchen garbage mode of handling is basically: landfill, incineration, composting, anaerobic fermentation, biodiesel, biological culture and the like.

Wherein, the landfill mode can occupy a large amount of land resources and can pollute the environment again; the incineration mode needs to consume more energy, although part of the incinerated energy can be used for generating heat and electricity, the heat and the electricity generation which can be really generated are less, and more resources need to be invested for treating the waste gas generated by the incineration; the composting mode is characterized in that water in the food and beverage waste residues is evaporated under the condition of manual control by virtue of microorganisms such as bacteria, actinomycetes and fungi which are widely distributed in the nature, the food and beverage waste residues are dried and ground, and the food and beverage waste residues are converted into organic compound fertilizers which can be used for agricultural production through a series of treatment procedures, so that harmful gases are prevented from being generated, but the treatment cycle time is too long, the generated organic compound fertilizers also have the defects of high salt content and the like, and the energy consumption is relatively high; the disadvantages of anaerobic fermentation are similar to compost; the biodiesel mode can only effectively utilize grease in the kitchen waste, and other organic matters are still treated according to other modes, so that the treatment is insufficient.

It is worth mentioning that the biological cultivation can effectively and completely utilize organic matters of the kitchen waste, but at present, no technology for completely treating the kitchen waste and cultivating the organisms is provided in China. The pretreatment equipment for the kitchen waste generally carries out primary treatment on the collected kitchen waste and then sends the kitchen waste into a crushing device, a pulping device and the like for subsequent treatment.

For example, the Chinese patent application number is: CN202010877190.0, published date: patent document 11 months 10 days in 2020 discloses a slurrying device is smashed to kitchen garbage, including smashing the cabin, smashing cabin cover board, feeder hopper, blanking fill and reducing mechanism shell, smash the left side in cabin and smash the for the storehouse axle subassembly swing joint, smash the for the storehouse axle subassembly and reducing mechanism shell fixed connection, the reducing mechanism shell with smash lug fixed connection, the right-hand member swing joint who smashes the for the storehouse axle subassembly has the packing ring the left side oil blanket cover of packing ring and smash for the storehouse axle subassembly swing joint, the left oil blanket clamp plate of oil blanket cover and smash for the storehouse axle subassembly swing joint.

Because kitchen garbage gets into the biax shredder and is torn into the fritter material, gets into slurrying separating centrifuge and separates after that, and the organic matter is beaten into the thick liquid, and light inorganic thing is like plastic film etc. then separated to the slag notch and is collected, and organic thick liquid is discharged from the discharge gate, and whole rubbish separation process is automatic to be accomplished.

The two schemes are kitchen waste treatment equipment, but the two schemes are not ideal in practical use, for example, more moisture is inevitably mixed in the initial collection process of the kitchen waste, the moisture forms swill in the waste, if the swill is not treated, the swill can cause influence in the subsequent pulping process of the kitchen waste, and meanwhile, the swill is collected to play a certain role in subsequent biological cultivation, and the two schemes do not treat the swill.
