One end releasable connection away from wind turbine has the storing string bag, the storing string bag to be externally connected to one or more cyclone dust removals point
From device.
The present inventor is by further investigation discovery, in the prior art（Such as in CN204412616U）, sent in wind turbine
Under the blowing of wind, Dust Dispersion is serious, and has considerable amount of dust to enter in light materials.Solid waste（Especially build
Building refuse waste）In light materials generally include polybag, foam, sawdust, plastic sheet, cloth etc., one in these substances
It can be used a bit as waste product, there is certain value, if the powder wherein containing dust such as waste concrete, useless masonry
Shape object is then difficult to as waste product be recycled, and limits the separation and utilization of the light materials, in addition so that should not adopt
With big wind turbine wind speed, separating effect is reduced.In addition, blowing for wind turbine is easy to cause Dust Dispersion, cause severe operational environment.
In the prior art, such as in the sorting of coal, inhibit flying upward for coal dust frequently with water spray humidification.However, in such as coal
Since operation object is single, such as be single coal in sorting or conveying, thus water spray humidification usually on a moving belt into
Row, it is in addition of less demanding to the mode of the position of water spray and water spray.The inventors discovered that in the light of building waste solid waste
In substance separation, if carrying out water spray humidification process on the conveyor belt, dust can be attached to light materials such as polybag, bubble
On foam, sawdust, this aspect can cause light materials to aggravate, so as to cause that can not isolate, in addition, even if a part of light materials obtain
To separation, the dust adhered to thereon can also limit the recycling of light materials.The inventors discovered that at the blanking end of material conveyor
Appropriate humidification is carried out at the blanking height set between the blanking gap, can effectively solve the problems, such as this.By in the position
It sets and is humidified, dust material can be largely attached on the solid waste heavy substance bulky grain for being more easy to attachment, and part
Dust can also can form heavy substance under humidified condition with agglomeration, to successfully be detached with light materials.Such humidification side
Formula rarely seen report in the separation of solid waste light materials.
The inventors discovered that the water of spraying humidification is preferably in a certain range.The present inventor it is conscientious the study found that for
The separation of light materials, water spray are preferably in building waste waste：Within the unit interval, (weight of the water of ejection)/(fall
Blanking weight)=0.01-0.05, preferably 0.03.When water spray is in the range, the dedusting in separation process can be made to imitate
Fruit is best.
In addition, in order to reach best spray effect, the droplet size of spraying there are certain requirements.It is particularly preferred that mist
Drip a diameter of 0.03~0.08mm, preferably 0.05mm.The study found that when droplet is the diameter, to dust in blanking
It is best to be atomized wetting effect, can be attached on heavy substance bulky grain or agglomerate into bulky grain, while also avoiding light
Substance is by excess humidity.
The quantity of the spraying device can be 1-10, preferably 3-8.

The distance between nozzle can be 15-20mm, and voltage can be 20-50kV.The electrostatic precipitator setting occurs in electrostatic
The opposite side of device, that is, electrostatic generator is spaced apart with electrostatic precipitator by blanking, and electrostatic generator is arranged in nozzle
Between blanking.Dust of the imperceptible dust such as grain size less than 0.1 μm may be implemented in the use of the electrostatic generator
Removal.
The present inventor has found by further further investigation, and under the blowing for the wind that wind turbine is sent out, the material of whereabouts is in throwing
Object line mode falls.In the prior art（Such as in CN204412616U）, the end face of feed inlet and the axial direction of collection bucket are hung down
Directly so that wind direction is vertical with end face, heavy substance such as concrete powder can be caused also to be blown into collection bucket in this way, to lead
Cause separating effect poor.The inventors discovered that by the end face of the feed inlet in inclined ramp obliquely（That is, being not provided with into
Conventional flushes form, but oblique lower left tilts）, and the axial angle θ of the inclined-plane and collection bucket is limited to specifically
45 ° -60 °, preferably from about 50 ° may be implemented end face and coincide with parabolical, just even if can if larger wind speed
It is accidentally blown into collection bucket to avoid heavy substance.This setup is not there is not yet report, the prior art also provide phase
The technical inspiration answered or introduction.
The present inventor has found that wind turbine is typically fixed on mounting bracket in the prior art after further research（Such as
It is using fixed mode in CN204412616U, i.e., irremovable）So that its air outlet is also usually solid at a distance from collection bucket
It is fixed constant.However, for different building waste types, the type and ratio of heavy substance and light materials are different, such wind turbine peace
Dress mode is difficult to meet the sorting needs of a plurality of types of building wastes.In the present invention, by making the wind turbine operability
Ground is mounted on mounting bracket, preferably can be along the axial movement of mounting bracket so that can be sorted according to different building wastes
It needs, freely adjusts the distance between itself and collection bucket.And in the prior art, it is realized often by more ventilating fan a variety of
The sorting of the building waste of type needs, and this mode consumes a large amount of human and material resources, financial resources, and also tends to need to interrupt
Operation process carrys out more ventilating fan.In comparison, the present invention is entirely without the wind turbine for needing to change different capacity.
In the present invention, movement of the wind turbine on mounting bracket can be controlled by computer, such as when material conveys

In the present invention, the lower part of the collection bucket is preferably provided with multiple pores 52.What the pore 52 allowed accidentally to be blown into
Heavy substance therefrom leaks out.The pore can be round hole.The inventors discovered that when building waste crushes, heavy substance and light
The particle size of substance is often different, such as the concrete of crushing is in often thinner powdered, and light materials are for example knitted
Object piece or sawdust often have larger particle size.The present inventor is by research, in serious analysis building waste crushed material
The diameter of the characteristics of light materials and heavy substance and difference, multiple pores set by selection bucket lower part is preferably 5.0mm-
10.0mm, preferably 6.0mm have found that such aperture has best weight substance screening effect.
The inventors discovered that when the outside of the storing string bag is not connected with cyclone dust removal separator, in order to prevent in light materials
The effusion of the dust such as the fine building concrete mixed, generally use is relatively thin, even closely knit mesh, but due to the use of relatively thin
Mesh, in the initial stage light materials of separation（Such as piece of cloth, sawdust）Mesh is just easily blocked, the gas generated so as to cause wind turbine
Flow the unsmooth flowing inside the light materials in collection bucket so that fine dust is accumulated in light materials, it is difficult to be detached.Work as connection
When cyclone dust removal separator so that larger mesh may be used, mesh is not easy to block at this time, to which the air-flow for making wind turbine generate exists
Smooth outflow inside light materials, to effectively separate fine solid particle and light materials.In the present invention, the net of the storing string bag
Hole can be 10-20 times of conventional storing string bag mesh diameter.
In addition, due to air-flow flowing it is smooth, avoid the wind that wind turbine blows and encounter the blocking blocks of collection bucket and return,
Fine dust is caused to be escaped from feed inlet.Further, since the use of larger aperture and the use of cyclone dust removal separator, enhancing
The separating effect of fine dust and light materials so that wind turbine wind speed can adjust in wide range, unlike prior art that
Sample needs to be arranged in a narrower range.
Preferably, the collection bucket can shake, to enhance screening effect.
