Description

A kind of whirlwind powder selector

Technical field

The utility model is related to aluminium powder screening installation technical field, particularly a kind of whirlwind powder selector.

Background technology

Superfine aluminium power has a wide range of applications in solar panel；The sorting for how realizing superfine aluminium power is this area The important topic of technical staff's research.

Whirlwind powder selector is using the gas-solid mixture centrifugal force produced when making to rotate at a high speed, by dust from air-flow The dry type gas-solid separation equipment separated.Conventional（Cut stream）The primary structure of tangential introducing-type cyclone separator is a circle Conically shaped, cylinder epimere tangential direction is equipped with the blast pipe of certain depth in insertion tube equipped with a gas inlet pipe, barrel top, There is the meal outlet for receiving fine powder at conically shaped bottom.Dust-contained airflow typically enters cyclone separator with 12-30m/s speed by air inlet pipe When, air-flow will be changed into circular motion from linear motion.The overwhelming majority of swirling eddy, it is twist downward along wall from cylinder Towards cone flowing.In addition, particle under the influence of centrifugal force, is thrown toward wall, grit is once contacted with wall, just loses inertia Power, and fall by the momentum of the speed axially downwards near wall along wall, into ash releasing tube, collecting bag is fallen into by meal outlet In.The outer rotational gas flow declined is rotated, is constantly flowed into during decline to the core of separator, forms centripetal radial direction gas Stream, this fraction, which is just constituted, rotates upward inward eddy.The direction of rotation of inside and outside eddy flow is identical.Final purification gas Outside through blast pipe displacer, a part of relatively dustshot got off that is not separated is also escaped therewith.

The said equipment is in use, the eddy flow of powder and air-flow in separator relies primarily on tangentially-arranged gas inlet pipe Drainage is carried out, drainage effect is poor.

Utility model content

The technical problems to be solved in the utility model is to provide that a kind of simple in construction, efficiency of separation is high, wieldy rotation Wind powder selector.

In order to solve the above technical problems, the whirlwind powder selector that the utility model is provided, including：It is concentric and from top to bottom according to The cylinder of secondary setting goes out air compartment, upper shell and back taper lower shell, and the cylinder goes out air compartment on the outside of the top of upper shell Extend in the upper shell, the bottom end opening that the cylinder goes out air compartment is arranged in the upper shell；This goes out the upper end of air compartment Chimney fan is radially provided with, so that the chimney fan is placed in outside the upper shell；The side wall upper part of the upper shell is set and institute State the tangent cyclone channel of the cylinder of upper shell, roof and bottom wall that the cyclone channel includes being parallel to each other, be parallel to each other it is interior Side wall and lateral wall；The cyclone channel is extended in upper shell by the outer wall of upper shell, and lateral wall and the institute of the cyclone channel The side wall for stating upper shell is integrally formed setting, madial wall with it is described go out air compartment side wall be integrally formed setting, roof and bottom wall edge Go out the wall spiral setting of air compartment side, and sealing is connected between roof and bottom wall and upper shell inwall, so as to form spiral in upper shell Downward helical duct；The bottom of the lower shell sets coarse powder to export, and bottom, the top of coarse powder outlet of the lower shell are set Put the auxiliary whirlwind entrance tangent with the conical surface of the lower shell；Also include motor, rotary shaft, rotating vane；The motor is set Put it is described go out air compartment top, the output shaft of the motor and the top of the rotary shaft are fixedly linked, to drive the rotary shaft Rotation；The bottom of the rotary shaft sets rotating vane, and the rotating vane, rotary shaft are arranged in the air-out room, for band Dynamic rotating vane rotates in air-out room；The rotary shaft is quill shaft, and the bottom of the hollow rotary shaft sets air inlet, Top in the air-out room sets gas outlet, so that the air of fine powder is mixed with upper shell to enter air-out in rotated axle Room, and then discharged through chimney fan；The inwall of upper shell and the back taper lower shell, the outer wall coating polytetrafluoroethylene (PTFE) for going out air compartment Coating, it is possible to prevente effectively from adhesion aluminium powder.

In use, aluminium powder to be sorted enters upper shell under the drive of high-speed air through cyclone channel, in upper shell Helical duct in side wall make adherent rotation vertically and move downward, reach behind back taper lower shell part, radius of turn contracting Screw under small and tangential velocity increase, air-flow and particle are made, after back taper lower shell bottom is reached, auxiliary whirlwind entrance It is passed through the compressed air of rotation, the rotary speed of air-flow and particle is maintained, and can be effectively increased separating effect, now gas In the aluminum particle more than cutting diameter be separated, export discharge from the coarse powder of lower shell bottom；Less than cutting diameter Aluminum particle slowly enter lower shell interior zone with air-flow, cone center vertically adverse current upwards motion, reach air-out The bottom of room, and the air inlet in the presence of rotating vane into rotary shaft bottom, rotated axle and chimney fan discharge.

Further, whirlwind powder selector also includes multiple pneumatic vibrator units located at the upper shell outer wall, for institute State upper shell to be vibrated, it is to avoid aluminium powder is adhered to.

Further, it is described go out air compartment bottom end opening be provided with filter screen, for prevent bulky grain aluminium powder enter be located at filter screen Air inlet on inner rotary shaft, influences the efficiency of separation.

The technique effect of utility model：（1）Whirlwind powder selector of the present utility model, it is simple in construction relative to prior art, Cheap, opereating specification is wide, not by temperature, pressure limit, and separative efficiency is high；（2）The upper end of whirlwind powder selector sets whirlwind Passage, carries out drainage, it is to avoid eddy flow is short of power to the powder for entering upper shell；（3）Upper shell and back taper lower shell it is interior Wall coats polytetrafluorethylecoatings coatings, it is possible to prevente effectively from adhesion aluminium powder；（4）Multiple pneumatic vibrator units of upper shell outer wall, are used Vibrated in upper shell, it is to avoid aluminium powder is adhered to；（5）The bottom of lower shell sets auxiliary whirlwind entrance, effectively improves sorting Efficiency.
