Abstract
The utility model relates to a dynamic coal mill separator which belongs to mechanical screening equipment. The separator comprises an upper cone body, a middle barrel body, a lower cone body A rotor consists of a rotating impeller and a cylindrical frame which are connected with each other, wherein the frame is provided with partition boards at intervals, and the rotor is installed in the middle barrel body. The utility model is characterized in that profiled adjustable vanes are arranged in the middle barrel body; movement clearance is formed among the profiled adjustable vanes, the rotor and the inner cone body of the middle barrel body. The utility model has the advantages that the fineness of coal powder is improved, the screen residue of coarse powder is reduced (the screen residue can be controlled less than 5% when the fineness of coal powder is 90 um), the production of an air swept coal mill can be increased, the specific energy consumption is reduced by 15-20%, the combustion velocity and efficiency in the process of turning clinker aggregate into fuel is increased, the fuel application range of baking system is widened, and the fuel cost is reduced.
Description
Technical field
The utility model relates to a kind of mechanical screening plant, dynamic coal milling powder-selecting machine.
Background technology
At present, cement production enterprise still all adopts the static mill separator that falls behind poor efficiency.Its separator does not have the rotor stepped zone, and fineness of pulverized coal can not be controlled, and quality of pc does not reach requirement, and power consumption is big, and equipment attrition is serious, yields poorly.
Summary of the invention
The purpose of this utility model provides a kind ofly has that rotor stepped zone, fineness of pulverized coal can be controlled, reliable, energy-efficient dynamic coal milling powder-selecting machine.
The utility model is achieved through the following technical solutions:
Dynamic coal milling powder-selecting machine, comprise upper cone, middle cylindrical shell, lower cone, rotor connects cylinder-shaped frame by rotary blade and forms, on framework, evenly be provided with dividing plate, rotor is located in the middle cylindrical shell, it is characterized in that be provided with special-shaped adjustable vane in the middle cylindrical shell, the inner core cone of special-shaped adjustable vane, rotor, middle cylindrical shell forms certain movement clearance.
The utility model has the advantages that: can improve fineness of pulverized coal, reduce meal and tail over.During 90 μ m, can be controlled at below 5%; Can improve wind and sweep the output of coal mill, reduce specific energy consumption 15-20%; Grog be can improve and fuel combustion speed and efficient burnt till; Can widen the firing system fuel scope of application, reduce fuel cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that A-A of the present utility model is to cutaway view.
The specific embodiment
See Fig. 1, Fig. 2, this device contour structures is that upper cone 4, middle cylindrical shell 15, lower cone 16 usefulness flanges are formed by connecting, transmission device is positioned at device top, connect planetary gear 8 transmissions by motor 1, planetary gear 8 connects rotor shaft 5, rotor shaft connects rotor 6, rotor 6 connects cylinder-shaped frame 10 by rotary blade 9 and forms, on framework 10, evenly be provided with dividing plate 11, rotor is located in the middle cylindrical shell, be provided with special-shaped adjustable vane 7 in the middle cylindrical shell, the inner core cone of special-shaped adjustable vane 7, rotor 6, middle cylindrical shell forms certain movement clearance; Be provided with fine powder air stream outlet 17 in the upper cone side, be provided with lubricating oil pipe 3 and escape pipe 2 on rotor shaft 5 tops; The lower cone bottom is provided with breeze airflow air inlet 12, is provided with an inner conical-tube 14 in the lower cone, and the inner conical-tube bottom connects meal discharging opening 13 (Fig. 1, Fig. 2).
The course of work of the present utility model is: sweep coal by wind and gall air inlet 12 broken, that coal dust after grinding enters dynamic coal milling powder-selecting machine with the wind, enter rotary blade 9 through adjustable vane 7, under the effect of its rotation, pulverized coal particle is subjected to the effect of three power: quality, centrifugal force, buoyancy.Big particle is big because of its quality, centrifugal force big, buoyancy is relatively little, under centrifugal action, is got rid of to adjustable vane 7, falls into inner conical-tube 14 because of losing kinetic energy behind the bump, discharges through discharging opening 13.The coal dust that particle is little is little because of its quality, centrifugal force is little, buoyancy is big relatively, is then discharged by fine powder air stream outlet 17 with the distinguished and admirable of come-up.
