as Fig. 2, 3, be fixed with internal bearing sleeve stationary pipes 28 outside described sorting unit inlet tube 1, one circle is installed in the toroidal cavity between conical shell 27 and described internal bearing sleeve stationary pipes 28 outside carries out the gear 34 of milling of mill in grades processing to returning powder, the described gear 34 of milling is cone structure, its gear shaft 35 the inners and outer end are loaded on internal bearing sleeve stationary pipes 28 and outer conical shell by milling device bearing 30 respectively, adjacent two gears of milling are intermeshing, the rotating shaft of one of them gear 34 of milling is through fixing with reduction box shaft coupling 32 and the output shaft of the variable-frequency motor 31 of milling.The pan mill that increases this time powder can the high efficiency fineness that significantly improves back powder, makes separation system already the coarse granule that screens be returned powder in this device and again mills, and makes most of defective time powder become qualified coal dust.
As Fig. 1, described inlet tube 1 top is provided with reamer 2, when described reamer 2 and the 1 top welding of sorting unit inlet tube, wind powder mixture become large reamer 2 gradually by circulation area, Speed Reduction and produce gravity separation, part bulky grain coal dust is sorted because of stall.Inner cone 5 is designed to the enclosed cavity body, is placed in outer conical shell 27, and coaxial with outer conical shell 27, be the wind powder mixture flow channel between inner cone, outer conical shell; Inner cone 5 is by the inner cone rotation variable-frequency motor 11 driving rotations that are placed in the sorting unit top.
As Fig. 2,3, return the powder milling device and be installed on powder outlet 15 positions oblique go back to, adopt wear-resistant gear, by crushing with grind and mill to returning powder.Enclose oblique time powder outlet 15 location arrangements one gear 34 of milling, the mill outer ring of an end by the milling device bearing of gear 34 fixed with outer end bearing holder (housing, cover) 33 and inner bearing holder (housing, cover) 36, outer end bearing holder (housing, cover) 33 and inner bearing holder (housing, cover) 36 weld with outer conical shell 27 and internal bearing sleeve stationary pipes 28 respectively, internal bearing sleeve stationary pipes 28 forms a closed cavity with sorting unit inlet tube 1, be connected with compressed air hose with clean instrument by pipeline in this closed cavity bottom, guarantee that cavity internal pressure is higher than oblique time powder outlet 15 internal pressures.The variable-frequency motor 31 of milling is connected with some gears 34 of milling by band reduction box shaft joint 32, regulates the frequency converter rotating speed, changes gear 34 rotating speeds of milling, and drives all the other gears of milling and rotates, and defective time powder of part is milled into qualified coal dust.
The milling device bearing 30 at described gear 34 two ends of milling all is installed on outside described toroidal cavity, so that milling device bearing 30 reduces the pollution of dust.
As Fig. 1, the lower outside of described inner cone 5 is equipped with axial flow wing blades 3.
The inner cone lower end arranges the axial flow wing blades, rotarily drive the wind powder mixture rotation by axial flow wing blades 3, part coarse granule coal dust is thrown to outer conical shell 27 inwalls because of centrifugation produces centrifugal classification, simultaneously, because making part be sorted the qualified coal dust that gets off to the speed-raising effect of wind powder mixture, blade rotary has an opportunity to participate in secondary sorting, reduce circulating ratio, improve the efficiency of separation, and promote sorting unit pressure head, reduction sorting unit resistance.
As Fig. 1, addendum cone 8 outsides of described inner cone 5 are installed with the movable vane rotor 10 that carries out centrifugal classification.
Inner cone 5 upper ends arrange the rotor that is comprised of movable vane rotor 10, and the coal dust that passes through multipass sort is done last centrifugal classification, and qualified coal dust enters sorting unit outlet 12, and defective coal dust falls along outer conical shell 27 inwalls after because of centrifugal classification stall.
As Fig. 6, the top board 38 at described outer conical shell 27 tops is provided with outlet 12, and the described outlet other end is opened on outlet header 14.
Described top board 38 tops are provided with four outlets 12, and the other end all is opened on outlet header 14, and four outlet 12 downstream direction spiral rotatings, and are connected with outlet header 14.
Four outlets 12 that the sorting unit outlet arranges have certain angle with sorting unit top board 38, its angle is consistent with the coal dust direction of rotation, and after laying out a mouthful house steward and rotating to an angle, with outlet header's 14 welding, to reduce outlet wearing and tearing and resistance, improve pulverized coal preparation system and exert oneself.
wind powder mixture is through sorting unit inlet tube 1, because reamer 2 areas increase, flow velocity reduces, the part coal dust is sorted because of gravity, a part of rough coal powder in the residue coal dust is because being sorted with 4 collisions of shock cone, inner cone integral-rotation due to 11 driver output axles 9 drives of inner cone rotation variable-frequency motor, a part of coal dust is with 3 rotations of axial flow wing blades, part coarse granule coal dust is sorted, after wind powder mixture process one-level baffle plate 6 and secondary baffle plate 7 guiding by axial flow wing blades 3, part coarse granule coal dust is sorted, the residue wind powder mixture rotates and is sorted through the movable vane rotor 10 that is comprised of blade, a part of coarse granule coal dust is fallen to outer conical shell, fall along outer conical shell, qualified coal dust enters four outlets 12, enter pulverized-coal collector after being mixed in outlet header 14, because the adjustable frequency motor rotating speed is adjustable, therefore, enlarged the fineness of pulverized coal adjustable extent, improved the pulverized coal fineness index, the qualified coal dust of minute quantity falls within addendum cone 8, and slide along addendum cone 8, when coarse granule coal dust and qualified coal dust intermixture drop down onto axial flow wing blades 3 place, because of 3 rotations of axial flow wing blades, promoted the qualified coal dust kinetic energy that partly is sorted, like this, greatly increased the probability that the qualified coal dust that partly is sorted carries out secondary sorting, therefore, improved the efficiency of separation of sorting unit, falling after rise extremely, the powder that returns of oblique time powder outlet 15 carries out mill in grades through the toothed disc of milling, make defective time pruinescence of part be milled into qualified coal dust, therefore, return the powder milling device and reduced the ratio of qualified coal dust in time powder, reduced resistance, improve the efficiency of separation, and then improved pulverized coal preparation system and exerted oneself, reduced unit power consumption of coal pulverizing.
