Construction waste screening, light substance sorting and dust collecting integrated equipment and method

Abstract

The invention belongs to the technical field of construction waste resource utilization, and particularly relates to construction waste screening, light substance sorting and dust collecting integrated equipment and method.The construction waste screening, light substance sorting and dust collecting integrated equipment comprises a sorting unit, the sorting unit comprises a circulating fan, the circulating fan is communicated with a sorting cavity through an air pipe, and the sorting cavity is communicated with the sorting unit; the electric butterfly valve is installed on the air pipe, a blowing device is arranged on the lateral lower portion of the bottom of the sorting cavity, a flow dividing device is arranged in the middle of the sorting cavity, a recycled aggregate discharging port and a light substance discharging port are formed in the bottom of the sorting cavity, the blowing device is aligned to the flow dividing device, and the flow dividing device is in an inverted cone shape. The invention provides equipment suitable for dry production, the air volume, the air pressure and the air direction can be adjusted, the position of the flow dividing device can be moved, and the double-layer air inlet and the double-layer adjustable blowing device are combined, so that the equipment can adapt to sorting of construction waste with different component proportions; the construction waste screening, light substance sorting and dust collecting integrated equipment and method can be used for screening construction wastes and remarkably improving the sorting efficiency.

Description

technical field [0001] The invention belongs to the technical field of resource utilization of construction waste, and in particular relates to an integrated equipment and method for construction waste screening, light material sorting and dust collection. Background technique [0002] current technology: [0003] Sorting of construction waste is an important part of realizing its resource utilization and reduction. Construction waste is mixed with some low-density components such as waste plastics, waste wood, and waste paper. It is necessary to separate the useful components through sorting. Come out and use it to separate harmful components. The basic principle of sorting is to use the difference in physical or chemical properties of materials to separate them. [0004] The common methods of sorting and removing impurities for light substances include manual sorting, hydraulic flotation and winnowing. [0005] In hydraulic flotation, construction waste is usually fed f...
