However, in the light materials in the prior art, not only detached including above patent document dust material content compared with Height makes the recycle value of light materials be severely limited, and in the high wind of wind turbine, operating environment dust is caused to fly It raises, is seriously polluted, bad environments.This field needs a kind of solid waste light materials separator of good dedusting effect, the dress Setting effectively to go out the building waste dust separation carried secretly in light materials.
Invention content
To overcome the above-mentioned technical problems in the prior art, the present inventor to be carried by further investigation and a large number of experiments Following technical scheme is supplied.
In one aspect of the invention, a kind of separator efficiently separating building waste dust is provided, which includes Material conveyor, material conveyor include carriage and conveyer belt, and material conveyor has when conveyer belt conveys in place for object Expect that the blanking end to fall, the end corresponding with the blanking end of the carriage are installed with mounting bracket, mounting bracket is equipped with For the collection bucket of the light materials in collection material and for receipts will to be blown into from the light materials in the material that the blanking end falls Wind turbine in collection bucket, collection bucket are equipped with feed inlet, and wind turbine is equipped with air outlet corresponding with the feed inlet of the collection bucket, It is equipped between the air outlet of wind turbine and the feed inlet of collection bucket below the blanking end of the material conveyor for from described Blanking end fall material by blanking gap;Outside between the blanking end and feed inlet top edge, facility have one A or multiple spraying humidifiers, humidify the material in dropping process;The end face of the feed inlet is in inclining obliquely The axial angle θ of inclined-plane, the inclined-plane and collection bucket is 45 ° -60 °;The wind turbine is operably mounted on mounting bracket;Institute The collection bucket stated includes the conveyance conduit of both ends open, and one end towards wind turbine of the conveyance conduit is equipped with the charging Mouthful, away from one end releasable connection of wind turbine have the storing string bag;It is axially disposed in the conveyance conduit to have spiral-poker, the spiral shell Revolving screw feeder has cylindrical section and conical section, feed inlet of the conical section close to collection bucket.
The inventors discovered that if relying solely on the air-supply strength of wind turbine, with the increase with wind turbine distance, strength of blowing Weaken comparatively fast, makes solid waste(Especially building waste waste)In light materials generally included polybag, foam, Sawdust, plastic sheet, cloth etc. can not be efficiently entering the storing string bag, therefore the present inventor is axially disposed in conveyance conduit has The light materials can be transported to the storing string bag by spiral-poker.It has surprisingly been found that the stirring due to spiral-poker is made With so that building waste dust material such as concrete powder can be easy to detach with above-mentioned light materials, avoid the powdered rubber It is adhered on light materials, is leaked out from the mesh of the storing string bag to be conducive to the powdered rubber, realized and the light materials Separation, analyzes its reason, is that there are notable differences for the two density.Especially in the case of spraying humidification, the spiral-poker Use just seem especially significant because when dust material humidification when, adhesive attraction significantly increases.
The spiral-poker has cylindrical section and conical section, feed inlet of the conical section close to collection bucket.Spiral-poker is long Degree is L, and the length of conical section is L ', and half taper is α.Taper segment length L ' is the 1/5-1/10 of spiral-poker length L, in the model When enclosing interior, conveying function and agitation function can be taken into account well.Half taper is that α is 15-20 °.If half taper α is less than 15 °, Then the spiral-poker is easy to block being blown into for light materials, if half taper α is more than 20 °, the stress for increasing spiral-poker is strong Angle value, and centrifugal action is too strong, is easy that light materials such as cloth is made to become entangled on screw feeder.In the prior art, it generally uses Screw feeder do not have conical section then, the present invention is specific for building waste light materials, devises above-mentioned conical section, plays spy Not good separating effect.
The end of the spiral-poker is not preferably flushed with the feed inlet of conveyance conduit, but in retraction conveyance conduit;Most Preferably, coaxial injector is the 1/5-1/3 of conveyance conduit length.In the coaxial injector, can while conveying light materials, Being blown into for light materials is not influenced.
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.In addition, blowing for wind turbine is easy to cause Dust Dispersion, operating environment is caused to dislike It is bad.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 Sorting or conveying in, be for example single coal since operation object is single, 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.
Preferably, the pyrrolidones of 1.0-5.0 weight % is preferably added in the water used in the spraying, to increase droplet Adhesiveness.
Preferably, there is at least one electrostatic generator in front of the nozzle of each atomizing humidifier(It is not shown)At least One electrostatic precipitator(It is not shown), the electrostatic generator is, for example, high-pressure electrostatic ring, the electrostatic generator with 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 needing to change wind turbine.
In the present invention, movement of the wind turbine on mounting bracket can be controlled by computer, such as when material conveys When the quantity of refuse of machine conveying is bigger, wind turbine can be made to become smaller at a distance from collection bucket, when the quantity of refuse of material conveyor conveying When smaller, wind turbine can be made to become larger at a distance from collection bucket, be formed and linked with material conveyor.
