Description

Domestic kitchen garbage centralized recycling and timely full-quantity pretreatment device for community connected with biomass utilization Technical Field The invention belongs to the technical field of mechanical devices, and relates to a kitchen waste pretreatment device, in particular to a household kitchen waste centralized recovery and timely full-quantity pretreatment device for communities which are connected with biomass utilization. Background The garbage classification and recovery treatment is a major national and civil strategic measure for sustainable development of the relationship. Domestic waste can be generally classified into four kinds of recyclable waste, kitchen waste, harmful waste and other waste. At present, aiming at the intelligent recyclable garbage classification recycling boxes (facilities) with various functions of weighing, crushing or compressing, point exchange and the like in the recyclable garbage market, most of the intelligent recyclable garbage classification recycling boxes (facilities) serve as public welfare projects and have a harmful garbage recycling function, so that the recycling treatment technology of the recyclable garbage and the harmful garbage in the household garbage is mature. However, the kitchen waste recycling device is limited to the special features that the household kitchen waste is small in daily production amount, is easy to rot and the like, and is difficult to recycle, so that most communities do not have special facilities for recycling kitchen waste, and even if a part of communities are provided with kitchen waste recycling boxes, the kitchen waste recycling boxes are also only 'containers' for intensively stacking kitchen waste, such as common flip-type plastic kitchen waste cans. As is well known, kitchen waste is perishable waste, and if the kitchen waste piled together cannot be treated in time, the problems of fly and insect breeding, odor emission, dirty water overflow and the like are inevitably caused even if the garbage can cover is covered. For solving the problem, a part of communities provide kitchen waste recycling bin with good sealing performance, but the kitchen waste recycling bin is frequently opened due to small daily production amount and dispersion of each household, so that the sealing performance of the kitchen waste recycling bin is not ensured. Moreover, more importantly, the volume of the common flip-type plastic kitchen garbage bin or the kitchen garbage recycling bin with good sealing performance in the community is not too large, and the situation that the garbage bin or the recycling bin is insufficient in volume is unavoidable, particularly, the kitchen garbage is put in nothing in the holiday and other time periods happens. Due to the factors, the community residents at present often divide household kitchen waste into other waste mixed loading and throwing, so that kitchen waste with extremely high proportion in the household waste (the proportion of the kitchen waste in the household waste is 50-60% as shown by relevant statistical data) cannot be effectively utilized as resources, and the disposal quantity and disposal difficulty of other waste are greatly increased (kitchen waste is high in water content and easy to be decomposed, and other waste mixed loading is liable to cause secondary pollution of other waste). Therefore, the household kitchen waste recycling treatment is a difficult point and a pain point in the household waste sorting recycling treatment at the present stage. Patent application number 202210480799.3 discloses an intelligent kitchen garbage processor that can automatic weighing, broken bag, collect disposal bag, kitchen garbage coarse crushing, solid-liquid separation, oil water separation. In the patent, part of liquid in crushed and rolled garbage passing through the crushing mechanism firstly flows through the solid-liquid separation mechanism to enter the oil-liquid separation mechanism, then the crushed garbage enters the solid-liquid separation mechanism, the solid and the liquid in the garbage are separated through extrusion of the solid-liquid separation mechanism, the solid is collected, the liquid flows into the oil-liquid separation mechanism, and grease in the liquid is separated and collected through operation of the oil-liquid separation mechanism. Therefore, the key idea of the patent is to separate and recycle the solid and grease in the kitchen waste, and the liquid with low recycling value is discharged as sewage. In fact, the liquid in the kitchen waste also belongs to recyclable materials capable of being recycled, and the liquid in the kitchen waste is separated out and is discharged as sewage, so that the recycling utilization rate of the kitchen waste is reduced, and the treatment amount of domestic sewage is increased. More importantly, the patent product cannot be effectively connected with the existing main stream mode of biomass utilization and disposal o
