Description

Landfill waste treatment system using sorting disk {Landfill waste treatment system using sorting disk}

The present invention relates to a landfill waste disposal system using a sorting disc. More specifically, the structure has been improved so that landfill waste is crushed and agitated by the rotational movement of the overlapping sorting discs, thereby improving the efficiency of soil sorting through the gap between the sorting discs. This is about a landfill waste disposal system using a sorting disk that can be improved.

Normally, methods such as landfill or incineration are used to dispose of waste. However, the landfill method has environmental problems and it is difficult to secure additional landfill sites, and the incineration method requires the construction of an incinerator due to environmental pollutants such as dioxin generated during combustion of waste. There are difficulties.

As waste disposal has emerged as a major social problem, technologies are being developed to select and recycle combustible materials, including tires, vinyl, and plastic, contained in waste to be landfilled or incinerated. However, combustible materials of various properties included in mixed waste are being developed. There is a lack of technology for selection.

Accordingly, in the previously disclosed registered patent No. 10-1814123, a particle size sorting step of inputting wastes of various properties into a circular sorter and sorting them by size; A wind power gravity sorting step in which wastes of a certain size or larger discharged in the particle size sorting step are sorted into combustibles and non-combustibles using an air circulation type first wind power sorter; A first SRF production step of producing SRF with a low water content ratio and high calorific value by pulverizing the combustible material discharged from the wind power gravity selection step in a grinder and removing earth dust, fine powder, and moisture from the combustible material through a dehydrator; After crushing the incombustible material discharged to the lower part in the wind power gravity sorting step with an impact crusher, it is supplied to a disk sorter together with waste of a certain size or less discharged to the lower part of the circular sorter, and after precise selection, soil of a certain size or less discharged to the lower part is A soil production step in which fine combustibles are removed using a cyclone to control suction wind speed and high-quality soil is produced; An aggregate production step of producing recycled aggregate by discharging the waste that falls and settles in a buoyancy separator during the wind power gravity sorting process by the air circulation type second wind separator after passing through the disc sorter; A technology including a second SRF production step of producing SRF below a certain standard from the lightweight combustibles selected by the air circulation type second wind separator has been previously proposed.

However, the above prior art classifies soil as high-quality soil that meets legal standards, and produces incombustible materials, including porcelain, as recycled aggregates that meet legal standards to maximize the use of waste as resources, but the primary particles are also selected for construction and living. , When the disk screen, which sorts waste according to the properties of landfill waste, wears out due to repeated use, the replacement work is complicated because the shaft must be completely disassembled to replace the disk, and when wire-shaped waste is wrapped around the disk and gets stuck. There is a problem that cannot be easily removed, and in order to sort and separate soil between disks, space must be secured between disks installed on neighboring axes. However, the soil easily gets stuck between disks, which has the disadvantage of lowering soil sorting efficiency.

Accordingly, the present invention was conceived to solve the above-mentioned problems, and the structure was improved so that landfill waste is crushed and agitated by the rotational movement of the overlapping sorting discs, thereby improving the efficiency of soil sorting through the gap between the sorting discs.
