After passing through the bag breaking crusher, the household garbage is crushed into small fragments with the diameter of 80mm and 100mm below, and the minimum particles of the rest components except the dregs reach below 5mm.
The fragments fall into a closed conveying belt, and obliquely upward low-pressure air is added in the falling process to relieve the falling speed of materials, and the materials have a preliminary dispersing effect, so that the materials fall onto the surface of the belt in a layering manner.
The conveying belt is used for conveying upwards at a certain angle, a high-pressure fan is arranged at the rear of a blanking part of the belt, stronger blowing force is generated on falling materials, the materials with larger surface areas and smaller density are floated upwards by wind power to fall to a far position, the materials with larger density, smaller granularity and smaller surface area fall vertically along with the belt after being conveyed out of the system, and therefore household garbage fragments are separated according to density, surface area and granularity differences, and the effect of preliminary classification of garbage is achieved.
The floating distance of each component of the garbage under the action of wind force is directly related to the density, the surface area and the granularity of each component, and the components with large surface area, low density and large granularity bear larger buoyancy force, can offset the action of most of gravity force, and can float to a far-distance area; the components with small surface area, high density and smaller granularity bear smaller buoyancy and cannot counteract the action of gravity, so that the floating distance is short and even the components fall directly.
The basic classification of household garbage can be realized by utilizing the buoyancy effect generated by the wind power. On the basis, according to the requirement of rear end recycling, the material blanking areas are divided into areas, the physical properties of material components contained in each blanking area are basically similar, blanking outlets are arranged and connected with post-sorting equipment, and the refining classification of each type of components is carried out.
The blanking area is generally divided into four areas, the blanking part with the farthest material is a light area, and the blanking part is mainly a large-area ultrathin material blanking area such as plastic films, paper sheets and the like in household garbage; the nearest blanking part of the material is a heavy area, mainly a blanking area of high-density small-volume heavy materials such as bricks, tiles, metal blocks, batteries, cement blocks and the like; the middle part is divided into a low-density area and a medium-density area, the low-density area is mainly a blanking area of combustible materials such as wood and textiles, and the medium-density area is mainly a blanking area of kitchen waste components and components with high water content.
In order to improve the classifying effect of the small household garbage in the high humidity area, a temporary storage dehydration chamber can be arranged in the receiving area after garbage is crushed, crushed garbage enters the temporary storage dehydration chamber and is dehydrated by using strong blast, the water content can be reduced by about 5-10%, and then the garbage is classified.
And (3) carrying out refined sorting on each type of materials by correspondingly using different refined sorting equipment for the primarily sorted materials collected in each blanking area. The means used include a drum screen, a magnetic separator, a wind separator, etc., and which means is determined by the post-recycling target is an ideal refining separation means as long as it is favorable for realizing the post-recycling target.
