The upper blades are evenly distributed between the upper circular plate and the first middle circular plate; the middle blades are evenly distributed between the first middle circular plate and the second middle circular plate; the lower blades are evenly distributed between the second middle circular plate and the lower circular plate; the lower blades are in rectangular structures; both the middle blades and the upper blades are in V-shaped structures; openings of the middle blades are wider than those of the upper blades; spacing of every two adjacent lower blades is wider than that of every two adjacent middle blades; spacing of every two adjacent middle blades is wider than that of every two adjacent upper blades.
Description
Technical field
The present invention relates to a kind of for powder concentrator, relate to a kind of powder concentrator multipass sort device specifically.
Background technology
In grinding process, crossing grinding phenomenon to reduce in mill, improving mill efficiency, in time material in mill should be drawn off, select qualified fine powder by powder concentrator, underproof meal is returned in mill simultaneously and reface.Above-mentioned powder concentrator comprises sorting unit, sorting unit is cage rotor, selecting in powder process, fine powder body in pulverized coal borne air flow by the gap between the uniform connecting rod of cage rotor excircle enter cage rotor inside, with circulated air rise enter in cyclone separator, powder obtains sedimentation and becomes finished product, the coarse dispersion in pulverized coal borne air flow due to speed little and cage rotor inside can not be entered, drop in meal collection cone with connecting rod collision rift relative to fine powder.Because the particle diameter of the powder becoming finished product above by sorting unit is single, particle size distribution range is narrow, therefore can not meet the requirement that different industries distributes to required material variable grain diameter.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of powder concentrator multipass sort device, powder in pulverized coal borne air flow can be divided variable grain diameter distribution material of hanking by this powder concentrator multipass sort device, thus the requirement that different industries distributes to required material variable grain diameter.
For solving the problems of the technologies described above, a kind of powder concentrator multipass sort of the present invention device, containing ring-like upper plate, plate one in annular, plate two in annular, circular lower plate, blade, Leaf and lower blade, ring-like upper plate, plate one in annular, in annular, plate two and circular lower plate are to lower and lower spacing arrangement, blade is uniform to be arranged in ring-like upper plate and annular between plate one, Leaf is uniform to be arranged in annular in plate one and annular between plate two, lower blade is uniform to be arranged in annular between plate two and circular lower plate, lower blade is rectangular configuration, Leaf and blade are v-shaped structure, the A/F of Leaf is wider than the A/F of blade, gap between adjacent lower vane is wider than the gap between adjacent Leaf, gap between adjacent Leaf is wider than the gap between adjacent upper vane.
In described ring-like upper plate, annular, in plate one, annular, plate two is identical with the structure of circular lower plate.
Described blade, Leaf are identical with the height of lower blade.
During above-mentioned powder concentrator multipass sort device work, because the gap between the gap between the gap between adjacent upper vane, adjacent Leaf, adjacent lower vane progressively increases progressively, therefore three layers of interlobate wind speed progressively successively decrease from top to bottom, thus can sub-elect variable grain diameter distribution material.

Detailed description of the invention
In Fig. 1, a kind of powder concentrator multipass sort device, containing plate 23, circular lower plate 1, blade 6, Leaf 4 and lower blade 2 in plate 1, annular in ring-like upper plate 7, annular.In ring-like upper plate 7, annular, in plate 1, annular, plate 23 and circular lower plate 1 arrange to lower and lower spacing.Blade 6 is uniform to be arranged in ring-like upper plate 7 and annular between plate 1, as shown in Figure 4.Leaf 4 is uniform to be arranged in annular in plate 1 and annular between plate 23, as shown in Figure 3.Lower blade 2 is uniform to be arranged in annular between plate 23 and circular lower plate 1, as shown in Figure 2.Blade 6 is rectangular configuration, and Leaf 4 and lower blade 2 are v-shaped structure, but the A/F of lower blade 2 is wider than the A/F of Leaf 4.Gap a between adjacent lower vane 2 is wider than the gap b between adjacent Leaf 4, and the gap b between adjacent Leaf 4 is wider than the gap c between adjacent upper vane 6.In described ring-like upper plate 7, annular, in plate 1, annular, plate 23 is identical with the structure of circular lower plate 1.Described blade 6, Leaf 4 are identical with the height of lower blade 2.During above-mentioned multipass sort device work, it is High Rotation Speed under driven by motor, and the air-flow mixing a large amount of solid dust particle passes from the gap that blade 6, Leaf 4 and lower blade 2 are respective and upwards enters follow-up gathering-device.In motion process, material particles is subject to three active forces, and namely the thrust of self gravitation, air-flow and blade rotary produce and produce from power.The size of centrifugal force realizes by adjusting rotary speed, and the size of airflow thrust regulates by regulating the air mass flow entered.The centrifugal force be subject to because of larger particles is greater than suffered airflow thrust, at this moment under self gravitation effect, falls downward enters grinding system and reprocesses, centrifugal force time suffered by thinner particle is less than the thrust of air-flow, just along with air-flow is blown into sorting unit together and continue to move upward enter in follow-up gathering-device collect become finished product warehouse-in.As can be seen from above, the size of finished particle is relevant with air velocity when passing through blade with the rotating speed of grading plant.Above-mentioned multipass sort device provides a kind of structure of differentiation multipass sort, the difference of wind area is crossed between the size adjustment blade by change impeller clearance, thus achieve three kinds of different wind speed, the material of variable grain diameter so just can be sub-elected under the condition of identical air quantity and rotating speed, meet the requirement that different industries distributes to the different-diameter of required various material, overcome the deficiency that selected by existing sorting unit, particle diameter is single, particle size distribution range is narrow.In the present embodiment, gap a between gap b between gap c between adjacent upper vane 6, adjacent Leaf 4, adjacent lower vane 2 progressively increases progressively, therefore three layers of interlobate wind speed progressively successively decrease from top to bottom, thus can sub-elect variable grain diameter distribution material.
