Abstract

PURPOSE: A method for sorting waste by dropping and wind is provided to determine the dropping height according to size and properties and adjust the size and location of wind according to the type, size and making amount of waste by disposing a blower in several variable shapes. CONSTITUTION: A mixed waste is carried to a proper height to have an enough dropping effect by using a transportation apparatus such as a conveyer belt(1) or the like, and then a vibrating chute(2) is covered to thinly spread the waste and drop the same. The dropping waste has a difference in dropping energy according to weight. The waste can be separated according to a weight difference by blowing wind by a variable blower(3). The waste can be separated into concrete, stones, plastic, woods, vinyl, paper and the like by controlling the dropping height and the location and strength of wind by the blower(3).

Description

The method of separating wastes with falling and wind force}

Ballistic separator, Air classifier, etc.

When sorting and separating wastes using drops and winds, the height of the drops is determined according to the size and characteristics of the wastes.In addition, the blower is installed in several variable forms so that the size and location of the winds depends on the type and size of wastes. Adjust. In the case of installing the blower, it is installed in a multi-stage, vertically forward shape, so that the effect of the wind can be enhanced, and light materials such as vinyl or paper can be reduced in the sorter. Falling waste must be thin and wide in order to be evenly affected by wind, and the location, size, and number of the bottom chute of the sorter will be determined by the purpose of sorting the material separated by weight.

1 is a diagram showing a waste sorting process using a drop and wind.

Mixed waste of the appropriate size (e.g. 40 mm or less) that has been crushed through a crusher, etc. (1) is transferred to the dropping position (e.g. 15 m height) through the conveyor belt, and (2) in a flat state Drop it. At this time, the chute makes the waste thin and constant while moving up and down and left and right. The drop height is determined by the type and size of the waste. The falling waste is blown by the blower, and the difference in the energy of the drop occurs depending on the weight of each item. . In order to make the most of the wind effect, the blower uses several variable blowers and adjusts the size and position of the wind according to the type, size and quantity of waste introduced. Wastes affected by the wind will collect the heaviest objects (4) through the chute (9) on the conveyor unit, and objects of medium weight, such as wood and plastic, (5) through the chute (10) by paper and vinyl The soil and sand are gathered by (6) chute and (11) conveyor. Light dust and fine soils are collected through the nets (8) and (7) in the dust collector.

It is expected to enhance the treatment effect of waste, recycle resources and protect the environment. For example, the sorted gravel and concrete can be used as a raw material for producing recycled recycled aggregate, and the waste is mixed to increase the recovery rate of scrap metal that cannot be separated by the magnetic separator, and according to each weight Separation of wood, vinyl, or paper soil can lead to better waste disposal.
