Abstract
The utility model provides a powder classifier used for mineral industry, medicine industry, chemical industry, etc. The powder classifier adopts an emission cone and a guiding cone arranged in a middle barrel as well as a stair type hermetic sealing space arranged at the outer ring at the joint of a distributor and a classified blade wheel, and accordingly avoids blending phenomenon. Three classified impellers are arranged in the horizontal direction, which increases classifying yield.
Description
The utility model relates to the grader field.
The powder separator that is used for materials such as classification mineral products, medicine, chemical industry in the prior art treats that at running the branch material directly enters classifying turbine by middle cylindrical shell through the spiral cyclone, there is less material directly not enter distributor like this by classifying turbine, cause batch mixing, the distributor of former powder separator and classifying turbine joint outer shroud are plane formula hermetic seal gap, the grain thickness batch mixing phenomenon that causes classified impeller discharging is more serious, and grading effect is poor; Former powder separator only is provided with a classifying turbine, and load is low; And do not go up feeding device, can not with the existing supporting use of grinding apparatus (Raymond mill).
The purpose of this utility model provides a kind ofly can reduce the batch mixing phenomenon, improve load and can with the matching used powder separator of existing grinding apparatus.
The technical solution of the utility model is: a kind of powder separator, comprise lower shell, spiral cyclone, middle cylindrical shell, upper shell, discharging cylindrical shell, distributor and classifying turbine, launch cone in addition and place middle cylindrical shell with the guiding cone, the classifying turbine horizontal positioned, distributor classifying turbine joint is equipped with step hermetic seal gap outward.
Advancement of technology scheme of the present utility model is: the emission cone is set directly over the spiral cyclone, the emission cone is the hollow staving of two sides opening, top opening flare, staving in the middle of the emission cone is fixed in spike, guiding cone top is screwed at distributor, and the part of the guiding cone conical surface is inserted in the horn opening of emission cone top; Also be provided with charge pipe on the middle cylindrical shell, classifying turbine is provided with three in the horizontal direction.
The utility model compared with prior art has following advantage:
(1). be provided with emission cone and guiding cone in middle cylindrical shell, make and treat that the branch material directly enters classifying turbine, distributor and classifying turbine joint outer shroud are provided with step hermetic seal gap, have avoided thickness batch mixing phenomenon.
(2). three classifying turbines are set in the horizontal direction, classification output are improved, charge pipe is being set on the middle cylindrical shell, make can with the supporting use of existing grinding apparatus.
The utility model will be further described below in conjunction with drawings and Examples.
Accompanying drawing 1 is structure master's cutaway view of the present utility model.
Embodiment: referring to accompanying drawing 1 and accompanying drawing 2, a kind of powder separator, spiral cyclone 2 is arranged between lower shell 1 and the middle cylindrical shell 6, fixing with screw 13, middle cylindrical shell 6 and upper shell 9 usefulness screws 13 are fixing, and discharging cylindrical shell 10 usefulness screws 13 are fixed in upper shell 9, launch cone 3 in addition and place middle cylindrical shell 6 with guiding cone 7, classifying turbine 11 horizontal positioned, distributor 8 and classifying turbine 11 joints are equipped with step hermetic seal gap 12 outward; Emission cone 3 is set directly over the spiral cyclone 2, emission cone 3 is hollow stavings of two sides opening, top opening flare, staving 6 in the middle of emission cone 3 usefulness spikes 4 are fixed in, guiding cone 7 tops are fixed on distributor 8 with screw 13, and the part of guiding cone 7 conical surfaces is inserted in the emission cone 3 top horn openings; Also be provided with charge pipe 5 on the middle cylindrical shell 6, classifying turbine 11 is provided with three in the horizontal direction, running: treat that the branch material enters emission cone 5 through spiral cyclone 3, because the bump of cone 9 conical surfaces that are subjected to leading changes direction, rush at the classifying turbine 19 of rotation, after material enters the classifying turbine that rotates at a high speed from the emission material that comes out of cone 5, when the centrifugal force of particle equals centripetal force, particle is exactly its Cut size, enters distributor 11, enters discharging cylindrical shell 14 by distributor 11 again; Can control required particle diameter with the rotating speed of regulating classifying turbine.
