The specific embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:
From bottom to top by outer cone cylindrical shell 10, inner cone cylindrical shell 9, air intake cylindrical shell 12, conical shell 13, select powder cylindrical shell 17, air-out cylindrical shell 18 is formed cylinder assembly, inner cone cylindrical shell 9 is positioned at outer cone cylindrical shell 10 inner chambers, inner cone cylindrical shell 9 links to each other with air intake cylindrical shell 12, be provided with dropping system 6 in the air intake cylindrical shell 12, feed hopper 23 is positioned at the inner chamber that selects powder cylindrical shell 17 and air-out cylindrical shell 18 of cylinder assembly top, air-out cylindrical shell 18 interlinks with 6 Whirlwind barrels 11 that are located at the cylinder assembly outside, the bottom discharging opening of 6 Whirlwind barrels 11 all interlinks with outer cone cylindrical shell 10, the bottom of outer cone cylindrical shell 10 is provided with fine powder discharging opening 7, and the fine powder that falls into outer cone cylindrical shell 10 through 6 Whirlwind barrels 11 is collected by fine powder discharging opening 7; The top of 6 Whirlwind barrels 11 all interlinks with wind converging tube 19, and wind converging tube 19 interlinks by blower fan and blast pipe 5, forms the closed cycle of wind.Rotor 16, spreading disk 14 assemblies place and select powder cylindrical shell 17 inner chambers, be installed in the lower end of main shaft 15, main shaft 15 flexibly connects with collar bush 22, and collar bush 22 is fixed on the support at top of cylinder assembly, and the other end of main shaft 15 links to each other with buncher 20 by pulley gear 21; Select the outside of powder cylindrical shell 17 to be provided with secondary wind inleting tube 1, select the secondary wind inleting tube 1 of powder cylindrical shell 17 to be connected by airduct 2 with the blast pipe 5 of air intake cylindrical shell 12, airduct 2 is provided with the adjusting valve 3 of adjustable rectification campaign amount size.
Of the present utility model constant at maintenance global cycle air quantity, guarantee under the prerequisite of Whirlwind barrel 11 efficient that by dividing air port 4, after adjusting valve 3 was regulated, powder cylindrical shell 17 was selected in tangential introducing with a certain proportion of wind, we are called secondary wind, use double-head arrow among the figure
Expression.Another part wind is then tangentially entered by air intake cylindrical shell 12, is called wind one time, represents with single arrow " → " among the figure.After one time wind levels tangentially entered air intake cylindrical shell 12, with certain lead angle α, progressively rotation rose to and selects in the powder cylindrical shell 17 under the promotion of follow-up air quantity, and it is spiral eddy flow.Secondary wind then is directly tangentially to enter the level rotary flow that selects powder cylindrical shell 17 with horizontal direction, so both exist certain flow direction poor.We can represent that the flow direction between them concerns with vector, promptly suppose the eddy flow of a wind and the eddy flow of secondary wind are launched, and use vector F
1Represent the spiral rising eddy flow of a wind, F
1With the angle of horizontal plane be α, use vector F
2Represent the level rotary flow of secondary wind, F
2With the angle of horizontal plane be 0 °, after both are synthetic, form from the horizontal by α
1The vector R of angle, the direction that its representative mixes the back eddy flow.α
1＜α, show that two strands of eddy flows mix after, the lead angle of eddy flow has reduced, and also promptly mixes the rate of climb of eddy flow and has been slowed down.
Regulate adjusting valve 3, make a certain proportion of secondary wind tangential import select in the powder cylindrical shell 17 after, formed strong level rotary flow, thereby strengthened the rotation air quantity of powder-separating area, increased secondary cut, improve the product particle grating.Secondary general mood stream fully mixes with general mood stream that rises in the shape of a spiral that is entered by air intake cylindrical shell 12 and the material that enters powder-separating area, and changes the rate of climb of this strand air-flow.And the air-flow rate of climb is one of principal element that influences particle separation diameter, and according to relevant formula as can be known, particle separation diameter is directly proportional with the square root of the rate of climb, thereby it can change fineness.Also increased simultaneously air and material in the time of staying of powder-separating area, thus disperse with wash away more abundant.Material is after separating, fine powder is through air-out cylindrical shell 18, Whirlwind barrel 11, fall into outer cone cylindrical shell 10, the dropping system 6 of meal in conical shell 13, air intake cylindrical shell 12, enter inner cone cylindrical shell 9, inner cone cylindrical shell 9 bottoms are provided with meal discharging opening 8, and the meal in the inner cone cylindrical shell 9 is collected by meal discharging opening 8.Secondary general mood stream and a general mood stream combine with the turning effort of rotor, form powerful gas cyclone, and its powerful shearing force is smashed the material of reuniting, and fine powder is separated, and creates conditions for efficiently selecting powder.
