Separation device for mixed construction waste and separation method thereof

Abstract

The invention provides a separation device for mixed construction waste and a separation method thereof. The separation device comprises a bulky waste crusher, a magnetic separator arranged behind thebulky waste crusher, compression equipment arranged behind the magnetic separator, a vibratory feeding platform, first-stage crushing equipment arranged behind the vibratory feeding platform, second-stage crushing equipment arranged behind the first-stage crushing equipment, first-stage screening equipment arranged behind the second-stage crushing equipment, second-stage screening equipment arranged behind the first-stage screening equipment, and a pulverizer arranged behind the second-stage screening equipment; the vibratory feeding platform comprises a feeding chute and a vibratory feeder,and is used for receiving other waste separated by a mechanical claw and carrying out secondary manual picking of bulky non-construction waste from the waste. The separation device has the advantagesof being efficient, environmentally friendly, capable of saving energy and high in production efficiency and is beneficial to obtaining concrete material with high purity, and then the concrete material which is separated out can be used as aggregate of recycled concrete to increase the utilization rate of resources.

[0002] With the rapid development of engineering construction and real estate industry, the amount of construction waste is also increasing year by year, and the proportion of demolition and decoration construction waste in construction waste is also increasing; the amount of construction waste in my country has accounted for urban waste 40%-50% of the total amount; the domestic construction waste treatment is still in its infancy, and the treatment methods and equipment need to be continuously upgraded; random stacking and landfilling of mixed construction waste not only seriously affects the city environment, encroaching on land, but also Cause soil, air and water pollution; construction waste contains many recyclable and reused resources, which can be sorted and recycled by using reasonable treatment technology and science and technology, and can also reduce the secondary pollution of resources; Under the background of advocating energy saving and emission reduction, efforts to reduce the generation of adulterated construction waste and improve its sorting and processing technology, improving the efficiency of waste sorting and optimizing the treatment effect are not only the needs of urban sanitation work, but also the future sustainable development. necessary for development

[0003] Because the composition of mixed construction waste is more complex than that of pure construction waste, most of it is solid waste, including soil, stones, concrete blocks, broken bricks, and wood, plastic, metal, glass and electrical appliances, etc. Waste; among them, non-polluting inorganic substances (including soil, stones, concrete blocks, and gravel) account for more than 70%; the garbage components are mixed with a large number of bulky garbage, cotton textiles, household garbage and other relatively difficult components. Increased the difficulty of processing doped construction waste; in the process of waste front-end processing, it is particularly important to sort and classify it, and the sorting effect of doped construction waste directly affects the subsequent middle-stage treatment and terminal resource treatment. Influence; in the current domestic research on the recycling of construction waste, according to the domestic garbage collection situation, the problem of garbage classification is particularly prominent; the research on the resource processing of doped construction waste generated during the construction process is mainly carried out by the relevant departments of urban sanitation, but the level of automation is low , especially in terms of garbage classification is still dominated by manual classification, labor-intensive, poor working environment, low economic benefits
