Detailed Description

As shown in fig. 1, the material is fed into an even distributor 2 through a feeding and conveying device 1, the even distributor 2 distributes the material evenly to make the material in the silo evenly distributed, the air-tight feeder 3 (the air-tight feeder 3 can prevent the outside air from entering the separation box, the air-tight feeder 3 adopts a revolving door type structure, the blades are made of conventional rubber silica gel), and the material is discharged into a vibration positive and negative pressure circulation winnowing device 4.

The structural principle of the vibrating positive-negative pressure circulating winnowing device 4 is as follows: the garbage is dispersed by bending and vibration, then is further blown away by air blowing (positive pressure), and then is separated from light objects (thin plastics, dry paper, dry leaves and the like) in the garbage oversize objects by the action of air suction (negative pressure).

There is the multichannel to bend in vibration positive negative pressure circulation wind selector 4, the material makes the material make a round trip to disperse to open with the help of the bending direction of multichannel bending at the in-process that drops, vibrating motor 8 is equipped with to bend the below, additional vibration effect makes the material drop more smoothly and makes the material vibration disperse the layering, the material drops the lower part magnetic separation roller 5 upper limit, utilize inside fixed semicircle magnetic rod, it is rotatory through outer stainless steel cylinder, it selects ferromagnetic substance to take magnetic material to rear end nonmagnetic region branch, ferromagnetic substance arranges the discharger A6 through closing wind and discharges.

The circulating air is powered by an induced draft fan 16, and blows to the multi-bend vibration positive and negative pressure circulating air separation device 4 according to the direction of the air pipe, the air speed and the air quantity required by different materials are different, the air speed and the air quantity of a corresponding air channel are adjusted by an air regulating valve A9 on the air pipe, the light materials (such as thin plastics, dry paper, dry leaves and the like) in the materials are extracted by negative pressure through an upper end negative pressure induced air pipe A19, the light materials in the scattered materials are taken out, the light materials flow into a cyclone material collector A13 through the air pipe to be collected, and the light materials are discharged through an air closing discharger D14, so that the first light material separation of the circulating air is realized.

The separated heavier materials enter a secondary circulating air separation system through a lower end air-closing discharger C10 and then enter a positive-negative pressure circulating air separation device 11.

The positive and negative pressure circulation winnowing device 11 and the front-stage vibration positive and negative pressure circulation winnowing device 4 have the same air duct and winnowing principle, heavy materials (relative to the light materials) are winnowed by two grades of medium and light materials (such as wet paper, wet leaves and thick plastics) and heavy materials (such as small bricks and small stones) again according to the difference of air speed and air quantity by adjusting the air regulating valve B12, the medium and light materials enter the corresponding cyclone material collector B17 through the air guide pipe B20, the medium and light materials are discharged through the air-blocking discharger E18 after secondary winnowing, and the materials without iron heavy materials are discharged through the air-blocking discharger B7.

Two sets of cyclone circulating air pass through the outlet of the cyclone collector and enter the circulating filter 15 through the main air pipe under negative pressure, and after entering the circulating filter 15 to filter dust-collecting air, the circulating air is sent to the vibrating positive and negative pressure circulating air separation device 4 through the draught fan 16 through the blast pipe A21 and sent to the positive and negative pressure circulating air separation equipment 11 through the blast pipe B22 for recycling. The emission of harmful gas is reduced, and the power of the fan is saved.
