Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 ~ 2, a kind of cement processing powder concentrator, comprises auxiliary fan blade 1, main blade 2, charging aperture 3, main shaft 4, decelerator 5, motor 6, spreading disk 7, shell 8, bracing frame 9, hot air intake 10, return air blade 11, discharging opening 12, meal outlet 13, exhaust outlet 14; Described shell 8 sidewall arranges bracing frame 9, and motor 6, decelerator 5 are installed in bracing frame 9 top; Described decelerator 5 is connected with the main shaft 4 being vertically set on shell 8 inside, and auxiliary fan blade 1 is installed in main shaft 4 bottom; Described auxiliary fan blade 1 top arranges main blade 2, and main blade 2 is communicated with the charging aperture 3 being arranged on shell 8 top; Described auxiliary fan blade 1 bottom arranges return air blade 10, and return air blade 10 bottom and meal export 13 is communicated with; Described meal mouth about 13 two ends arrange exhaust outlet 14 and hot air intake 10 respectively, and exhaust outlet 14, hot air intake 10 are communicated with shell 8; Described shell 8 bottom is provided with discharging opening 12.
As optimisation technique scheme of the present invention: also comprise spreading disk 7, described spreading disk 7 is embedded in auxiliary fan blade 1 inside and is arranged on main shaft 4 bottom; Support frame as described above 9 is a kind of bracing frame 9 of decussate texture, and bracing frame 9 two ends are welded on shell 8 sidewall; Described shell 8 is a kind of shell 8 of pyramidal structure.
As operation principle of the present invention: the special powder concentrator of cement in working order under, motor 6 drives main shaft 4 to rotate by transmission device, material enters in separating chamber by the charging aperture 3 being located at top, powder concentrator room, again by be arranged on middle meal collection cone up and down between two cones and logical powder pipeline drop on spreading disk 7, spreading disk 7 rotates with main shaft 4, material is under the effect of centrifugal inertial force, evenly spread out to surrounding, the material machine of giving a dinner for a visitor from afar outside disperseed enters the action of high-speed airflow of separating chamber by hot air intake 10 under, the effect that coarse particles in material is subject to centrifugal inertial force is thrown toward the internal face of separating chamber.Collision rift loses kinetic energy and slides along wall, falling meal receives in cone, remaining particle is rolled by the air-flow rotating rising, through the active region of main blade 2, under the shock of main blade 2, some coarse powder particles is thrown the internal face of separating chamber again, collision rift loses kinetic energy and slides along wall, falls in meal collection cone, and middle meal and fine powder are by after main blade 2, under the effect of ascending air, continue to rise through vertical guide vane and enter secondary powder-separating area.Dust-contained airflow, under the strong and stable plane cylinder effect of the cage-type rotor formation rotated, is lost kinetic energy after making middle meal be thrown to auxiliary fan blade 1 under the influence of centrifugal force, falls in middle meal collection cone, discharged by middle meal pipe.Satisfactory fine powder enters its inside through cage-type rotor, enters in high-efficient low-resistance type cyclone separator with circulated air, is slipped to subsequently in fines collection cone and becomes finished product.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any Reference numeral in claim should be considered as the claim involved by limiting.The above; be only preferred embodiment of the present invention; not in order to limit the present invention, every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solution of the present invention.
