Description
Technical field
The utility model belongs to powder equipment field, specifically relates to a kind of powder concentrator.
Background technology
Powder concentrator has a lot of types, and the material that different types is applicable to is also different, and different models also makes the requirement of fineness of materials according to client.Generally common powder concentrator has cyclone type powder sorting machine, three composition dividing powder separating machine, centrifugal classifier, and coal grinds special powder concentrator, the special powder concentrator of calcium powder etc.Also developed out a lot of high-efficient powder concentrator afterwards, efficient three composition dividing powder separating machine, they improve deficiency on original basis, improve the kind of new generation of output
Even if but development tertiary air powder concentrator, it is not high to the efficiency of separation of powder, exist much waste, thus cannot realize truly efficiently select powder.Existingly set up dropping system at inner casing conical section, the effect playing supplementary classification and again disperse, to help in centrifugal classifier, at the not dispersed material of bulk cargo dish, to be again separated classification.
Existing dropping system is circumference type, material disperses at dropping system, under the influence of centrifugal force, dropping system once increases from internal layer to outer field particle diameter, dropping system is provided with air outlet, coarse grained material is gone out from cylindrical tangent line air port, can falling from bottom layer discharging mouth for granule of internal layer.But thisly belong to circular apparatus, after outer field coarse granule flies out, internal layer relatively fine particle will fly to outer tangent line, also fly out from the air outlet being positioned at outer tangent line, flowed out by discharging opening to shell, therefore, existing dropping system does not play good grading effect.
Utility model content
The technical problem that the utility model solves is, improves the efficiency of dropping system.Technical scheme is to provide a kind of powder concentrator.
Be specially: powder concentrator, comprise drive unit, main shaft, bend pipe, charging aperture, support, air inlet, secondary air inlet, a fine powder air outlet, characterized by further comprising drip ash bucket, mill tail deduster; Described drip ash bucket is positioned at below fine powder air outlet, comprise two three air inlets, two shoot doors, wherein the outside diameter of drip ash bucket becomes large to tangent line air outlet from three air inlet internal tangents more gradually to shoot door, this ensure that the outer field coarse granule receiving larger centrifugal force of drip ash bucket is preferentially selected, a little bit smaller particle subsequently, the resistance being subject to outer wall when not flying out completely makes it continue to be subject to the effect of centrifugal force, stays in drip ash bucket.
The material of described drip ash bucket is wear-resisting alloy steel.
Described drip ash bucket is connected with main shaft by the draw-in groove on main shaft, and main shaft drives the rotation of drip ash bucket by rotating band.
Described drive unit comprises motor, shaft coupling, decelerator, and wherein motor connection shaft coupling, shaft coupling connection reducer, decelerator connect main shaft by shaft coupling.
Described motor frequency is 50Hz, and rotating speed is 1800r/min, and the rotating speed of reductor and the rotating ratio of motor are 1:8.
Described mill tail deduster is positioned at drip ash bucket shell, and connect discharging opening, the interior diameter of described mill tail deduster is greater than discharging opening external diameter, for collect powder concentrator shell collect less than fine powder, improve the grading effect of powder concentrator to particle, and classification efficiency; Improve the collection efficiency to fine powder.
The beneficial effects of the utility model are:
By improving the drip ash bucket of powder concentrator, its outside dimension being changed, well realizing the grading effect of the dispersion process again of the not dispersed thicker material in drip ash bucket; Increase mill tail deduster in addition, for collect powder concentrator shell collect less than fine powder, improve the grading effect of powder concentrator to particle, and classification efficiency; Improve the collection efficiency to fine powder.
