Technical field
The utility model relates to a kind of device from powder separation powder, particularly uses the twin-stage combined type eddy current powder concentrator in the cement production process.
Background technology
At present, in cement production process, cross the grinding phenomenon in the mill, improve mill efficiency, must in time material in the mill be drawn off, after powder selection device is selected qualified fine powder product, underproof meal is returned in the mill reface simultaneously in order to reduce.Current, in chemical industry powder, cement production process, comparatively advanced powder selection device commonly used has O-sepa efficient vortex powder concentrator.The basic functional principle of this class powder concentrator is: under the effect of system's air-introduced machine, mill tail dusty gas and secondary wind are entered by first and second blast pipe, enter grading room formation through wind blade and select the powder air-flow, because acting on of rotating vortex blade forms eddy current in the powder-separating area.Powder to be fractionated feeds from powder inlet pipe, fall into cage rotor top powder under the rotation of cage rotor and disperseed laggard eddy current of going into powder-separating area, the eddy current air-flow of material is carried in formation secretly, in the air-flow powder of different-grain diameter under the acting in conjunction of suction force, centrifugal force, gravity by sorting, fine powder is crossed cage rotor with air communication and is discharged from discharge pipe, enter the outer efficient dust collector of body, be collected and get off to be finished product.Meal lands from top to down or is thrown to inwall in separating chamber and drops to ash bucket again, is discharged by the discharging opening of ash bucket bottom, reenters grinding machine and forms closed-circuit grinding system.Accompany fine powder owing to also contain in the meal powder that falls, not through classification once more, these fine powders can not be separated from the meal powder in dropping process, thereby this class powder concentrator exists effectiveness of classification and the low shortcoming of grinding efficiency.
The utility model content
There are effectiveness of classification and the low deficiency of grinding efficiency in order to overcome existing O-sepa powder concentrator.The purpose of this utility model is to provide a kind of twin-stage combined type eddy current powder concentrator, and this powder concentrator can improve effectiveness of classification and grinding efficiency effectively in the manufacture of cement grinding process.
The technical scheme that its technical problem that solves the utility model adopts is: comprise powder inlet pipe, transmission device, vertical shaft, guide vane, striker plate, the meal collection cone, cage rotor, housing, also contain discharge pipe, cyclone collector, material take-off clone, propeller formula spreading disk, material-dropping clone, air inlet, the fines collection awl, the below of guide vane is provided with material take-off clone, propeller formula spreading disk is arranged on the lower end of vertical shaft and below material take-off clone, the below of propeller formula spreading disk is provided with material-dropping clone, lower part of frame is provided with air inlet, the below of housing is provided with the meal collection cone, the outside of meal collection cone is provided with the fines collection awl, the top of fines collection awl is provided with cyclone collector, the top of cyclone collector and the top of housing link, and discharge pipe is arranged on the top of cyclone collector and links with the top of cyclone collector.
The beneficial effects of the utility model are, owing to below cage rotor and guide vane, be provided with material take-off clone and propeller formula spreading disk, drop on the propeller formula spreading disk through material take-off clone when containing the meal that accompanies fine powder, propeller formula spreading disk rotates with vertical shaft, powder under the effect of centrifugal inertial force to around spread out, simultaneously powder is upwards kicked up by the effect of the circulated air air-flow that enters from air inlet, thinner powder in the powder is the suspended dispersed shape, enter grading room formation through wind blade and select the powder air-flow, under the effect of cage rotor, in powder-separating area, form eddy current.By sorting, qualified fine powder enters cyclone collector with air-flow and is collected the powder of different-grain diameter under the acting in conjunction of suction force, centrifugal force, gravity in the air-flow.In this process, contain the meal that accompanies fine powder through once more sorting, fully remove the fine powder that is mixed in the meal.Therefore improve the effectiveness of classification and the grinding efficiency of powder concentrator.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
