Summary of the invention
The purpose of this utility model provides a kind of multistage air-flow combined type powder concentrator, and it has solved in the prior art particularly that there are the problems referred to above in the O-sepa powder concentrator, has improved the powder concentrator grinding efficiency, has reduced the specific energy consumption of product significantly.
The purpose of this utility model is achieved through the following technical solutions:
Multistage air-flow combined type powder concentrator of the present utility model, include upper shell, rotor and spreading disk, guide vane, lower cone, have annular charging aperture on the top board of its upper shell, both sides are first and second airduct of tangential air intake, the rotor upper disk surface is a spreading disk, annular spreading back-up ring is housed between the top board of spreading disk edge and upper shell, it between rotor outer ring and the guide vane annular graded region, rotor is fixed on by upper shaft sleeve on the top board of upper shell, and the impeller of rotor is contained on the interior power transmission shaft of axle sleeve.
In the multistage air-flow combined type powder concentrator of the present utility model, described annular spreading back-up ring is for regulating the annular spreading back-up ring of distance between itself and the spreading disk; Have annular charging aperture on the top board of the multistage air-flow combined type of the utility model powder concentrator upper shell, the quantity of annular charging aperture is 2～4; In the described lower cone inner cone is housed; The tertiary air powder selection device is equipped with in the lower cone bottom; Tertiary air powder selection device on the multistage air-flow combined type of the utility model powder concentrator is the tangential whirlwind import of multi-stage annular.
The utility model advantage compared to existing technology:
Material is added to spreading disk by the annular charging aperture on the upper shell, and annular spreading back-up ring is housed on the spreading disk edge, and distance is adjustable between back-up ring and spreading disk, makes materials flow evenly to spread out, and forms equal refining curtain.Air-flow tangentially enters volute shape cylindrical shell by first and second airduct on the upper shell, through the annular graded region between guide vane and the rotor, material is carried out sorting, and carry material and enter rotor, thick material is thrown toward guide vane under the rotor centrifugal action, thin material enters internal rotor with air-flow, enters deduster again and is collected.Material after the process sorting to lower cone, is subjected to the multilayer rinsing of tertiary air powder selection device along the barrel landing once more, makes that fine powder is fully washed out.Inner cone is housed in the lower cone, has improved the cross section wind speed of tertiary air, fine powder arrives powder-separating area rapidly under the drive of tertiary air, improved grinding efficiency, has reduced the specific energy consumption of product significantly.
