Description of drawings
Accompanying drawing is the structural representation of the utility model one embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to accompanying drawing, the sorting unit 1 of present embodiment comprises upper cavity 12 and lower chamber 11, upper cavity 12 sidewalls are provided with thin ash outlet 7, a truncated cone-shaped turbine 2 is housed in lower chamber 11,100 blades 3 through Wear-resistant Treatment are housed, the entad straight line deflection 20 degree angles at the end face of blade 3 and 2 centers of turbine on the turbine 2; The central shaft of turbine 2 and the frequency control motor at top 5 link by shaft coupling, and motor 5 tail ends are fixed on turbine 2 central shafts with nut 13, and are furnished with floor clip; Lower chamber 11 side wall upper part are provided with charging aperture 6, and adjustment cone 4 moving up and down is housed in lower chamber 11, are used to regulate the following grey gap of coarse grain, the control flyash time of staying of particulate in cavity 11, guarantee that the grain dust sorting is clean; Be provided with skewer plate valve and blocking valve (not drawing among the figure) between lower chamber 11 lower ends and the conveying worm 9, the fly ash micro-sphere mangcorn stage material 8 that comes out from sorting unit lower chamber 11 lower ends enters conveying worm 9 by skewer plate valve and blocking valve, under the helical feed of conveying worm 9, enter grading plant 14, the grain dust that sub-elects is discharged, is collected from the thin ash outlet 7 of upper cavity 12 sidewalls.
Grading plant 14 is positioned at the discharging opening of conveying worm 9, and its function is that the glass microballoon mangcorn stage material that will remove fine dust carries out classification by particle diameter, weight.The pressure chamber of grading plant 14 is but that the distribution of air flow Curtain cloth 15 of 5 ° and up-down vibration is separated into two parts up and down by gradient, and the upper strata is separated into about 17 and 16 two sections by air door 21, and lower floor is separated into about 19,18 two sections by dividing plate 20; Conveying worm 9 discharging openings are installed in the port of 17 sections; The glass microballoon particle collecting duct 22,23,24 of different-grain diameter is connected to the port of 16 sections.19 sections bottom is provided with vibrator 25,18 sections bottom and is provided with vibrator 26; On the 17 section top frameworks exhausting conduit 27 and blade 28 are housed; Air supply device (not drawing among the figure) provides pressure wind for 18,19 sections, and the wind-force size is controlled respectively by valve 30,29, and the whole air-flows that enter 18,19 sections are by the in addition ionization of being located between air supply device and the valve 29,30 of ion generator 31; Glass microballoon granulate mixture to be fractionated is arranged by conveying worm 9 input pressure chambers 17 sections, collect and particle is flowed for the ease of glass microballoon particle collecting duct 22,23,24; The gradient of distribution of air flow Curtain cloth 15 can be adjusted by the gradient of adjusting pressure chamber's integral body; The joint of two sections 16,17 in pressure chamber is provided with supporting 32, is provided with adjustable supporting 33,34 at two ends; By the height of suitable adjusting 33,34, can make the gradient of distribution of air flow Curtain cloth 15 in section 17 greater than the gradient in section 16.
Conveying worm 9 is conveyers of a kind of sealing that glass microballoon particle inflow section 17 can be able to be keep-uped pressure again; Pressure air footpath valve 29 inflow sections 19; Gas distributes Curtain cloth 15 to be used for setting up uniform pressure at section 19, so that the uniform airflow through this Curtain to be provided.
Pass the cross-current that the air-flow that distributes Curtain cloth 15 produces the direction of motion of relative conveying worm 9 input glass microballoon particles; The glass microballoon particle from conveying worm 9 exits with towards the motion of the direction of glass microballoon particle collecting duct 22-24, and air-flow to be the direction of motion of crossing the glass microballoon particle usually flow, this cross-current makes the glass microballoon particle be suspended in respectively on the different level of grading plant 14 pressure chamber by the difference of its particle diameter and weight.
Air door 21 can move up and down adjustment, is used to control the glass microballoon particle size that flows into section 17.As with its lifting, then allow less glass microballoon particle to pass through; Descend, then those are blocked than small particle, it is discharged from pressure chamber through the conduit 27 of bleeding; Air door 21 is arranged on to make and allows diameter to enter on the height of section 16 greater than 1 micron particle; Roughly 1 micron and littler particle are then discharged through the conduit 27 of bleeding with air-flow.
Vibrator 25 makes distribution of air flow Curtain cloth 15 produce vibration.This vibration can prevent that the hole of Curtain cloth 15 from blocking, and is convenient to make the heavier movement of particles that is suspended by crossflow.Simultaneously, the pressure wave because of the vibration of distribution of air flow Curtain cloth 15 forms can make between the thick pearl suspended particulate and produce rubbing action, and this rubbing action is with between the broken glass microballon or the reunion between particulate and the dust, to reach better separation grading effect.
Because the friction between the glass microballoon can make particle institute static electrification lotus increase, and in order to eliminate this adverse effect, ion generator 31 is set, and makes the air-flow ionization of passing distribution of air flow Curtain cloth 15.
In sorting unit 1, remove on the part dust fine grained basis, the glass microballoon particle is finished further purification and preliminary classification in the section 17 of the pressure chamber of grading plant 14, just in this cavity, further remove dust and do not have the fine grained of much economic use values, with them from the conduit 27 discharge systems of bleeding; Glass microballoon particle treated in section 17 flow to section 16 from air door 21; The gradient of distribution of air flow Curtain cloth is less than the gradient of Curtain cloth in the section 17 in the section 16, because enter the particle that the particle of section 16 is less than 17 sections, in order to keep a continuous system, the movement velocity of the particle on the Curtain cloth is more even more ideal; In section 16, the glass microballoon particle is subjected to the effect of the cross-current of ionizing air again, makes glass microballoon be suspended in different level heights by its particle diameter respectively with weight and is collected conduit 22-24 respectively and collects, thereby reach the purpose of classification.Can by the different-grain diameter of required glass microballoon, the collecting duct of varying number be set at pressure chamber's 16 section end differing heights according to product utilization purpose or market demand.
Said in this specification " crossflow " is not strict crossflow, it refers to and the particle direction of motion air-flow of quadrature roughly, the glass microballoon particle is suspended on the differentiated levels that distributes Curtain cloth 15 tops, to reach the purpose of classification by its dimension and weight.
" flyash " used herein speech refers to not only comprises the material that is produced by solid fuel ignition, the various components that also comprise the fine coal that processes with lump coal include components such as the glass microballoon material that closes metal powder, carbon dust and various size fractionated and dust.And all components is all distinguished by its main chemical.This identification is not show any component 100% pure, perhaps reaches 100% by the separation that the present invention finished.
In flyash dry separation glass microballoon product technology, known magnetic separator, decarburization machine are contacted with the utility model, can produce metal powder, carbon dust, the glass microballoon product and the dust of various size fractionated.
