Embodiment 1

[0035] Such as figure 1 Shown, a kind of embodiment of construction waste light matter sorting and sorting device, the winnowing separation device in this embodiment comprises material conveyer, and material conveyer comprises conveyer rack 2 and conveyer belt 1, and material conveyer has When the belt 1 is conveyed in place, it is the blanking end 11 for the material to fall. The material conveyor here extends obliquely upward along the feeding direction of the conveyor belt. The blanking end 11 is located at the upper end of the conveyor frame. The corresponding upper end of the blanking end 11 is fixedly provided with a mounting frame 3, and the mounting frame 3 is provided with a collecting bucket 5 for collecting light matter in the material and a collection bucket 5 for collecting the light matter from the material falling from the blanking end 11. The light matter blown into the blower fan 4 in the collection bucket, the collection bucket 5 is provided with a feed inlet...

Embodiment 2

[0038] The difference between embodiment 2 and embodiment 1 is that a plurality of fine holes 52 are provided in the lower part of the collecting bucket, and the diameter of the fine holes is 2.0 mm.

[0039] Evaluate sorting effectiveness by checking the content of heavy material in the collection hopper. In this example, the heavy matter content in the collected light matter was 3% by weight.

Abstract

The invention provides sorting and separating equipment for light objects in building rubbish. The sorting and separating equipment comprises a material conveyor. The material conveyor comprises a conveying frame and a conveying belt and is provided with a water dropping end allowing materials to drop when the conveying belt achieves conveying in place. A mounting rack is fixedly arranged at the end, corresponding to the material dropping end, of the conveying frame and provided with a collecting hopper for collecting the light objects in the materials and a draught fan for blowing the light objects in the materials dropping from the material dropping end into the collecting hopper. In the equipment, the axial included angle theta between the end face of a feeding opening and the collecting hopper ranges from 45 degrees to 60 degrees, and the sorting and separating effect is greatly improved.

Description

technical field [0001] The invention relates to a sorting and sorting device for light materials of construction waste, in particular to a device for sorting and sorting light materials of construction waste. Background technique [0002] Construction waste mainly refers to all kinds of waste such as soil, waste residue, mortar, etc. generated during the construction, repair, demolition of various structures and buildings by construction units or individuals, and house decoration. The basic composition of construction waste produced by different types of building structures is the same, and the main components include soil, scattered mortar, waste residue, asphalt concrete fragments, reinforced concrete pile heads left after piling, cement concrete, masonry produced by chiseling, All kinds of waste metal, wood, packaging materials of various building materials, wall insulation boards, waste generated in the decoration process and other wastes. [0003] In the construction...
