Description
Technical field
The utility model relates to a kind of in the grinding process of manufacture of cement, with the equipment that solid material particle carries out classification by its particle size, and circulation powder concentrator in particularly a kind of K type.
Background technology
In the grinding process of manufacture of cement, solid material particle need be carried out classification by size and handle.Classifying equipoment commonly used at present is the air powder concentrator, and it is a kind of effect by air-flow, makes material particles carry out the equipment of classification by size.The present cement industry of China, use air powder concentrator comparatively widely mainly contains two types, and a kind of is that rotator type powder concentrator, another kind are the O-Sepa powder concentrators.The basic functional principle of rotator type powder concentrator is: material is entered in the powder concentrator by powder concentrator top feed pipe, fall with rotor all-in-one-piece bulk cargo dish on, under the rotary action of bulk cargo dish, material be subjected on the one hand the centrifugal inertial force effect to around shed, be subjected to simultaneously upwards kicking up under the circulation wind action that ascending air that the bulk cargo dish produces and external blower fan enter powder concentrator, above spreading disk, form the material boiling.The fine powder of material upwards hikes up, and is dispersity, gets rid of internal face to powder concentrator and thicker or heavier powder is subjected to the effect of inertia force, loses kinetic energy after the collision to slide along wall, falls in the meal collection cone.And the fine powder that hikes up continues under the circulation wind action to rising, by the fine powder of cage rotor, enter in the outer buttons air duct with circulated air, and the powder sedimentation, falling into the fines collection awl at last becomes finished product.Circulated air enters discharge pipe extremely down in the whirlwind tube, discharge pipe and circulating fan import are joined, and the air inlet of circulating fan outlet and powder concentrator joins, and circulated air obtains circulation.Because material freely falls from material-falling hopper, can not fall equably on the spreading disk, make the dispersed variation of spreading disk material casting, material above spreading disk, can not get abundant boiling,, this zone powder density differs very big everywhere, thereby the grinding efficiency of powder concentrator reduced.The basic functional principle of O-Sepa powder concentrator is: air-flow enters grading room by first and second blast pipe and forms and select the powder air-flow, because acting on of the cage rotor of rotation forms eddy current in the powder-separating area.Powder freely feeds from powder inlet pipe, fall into the charging tray of removing on the cage rotor, material is disperseed in the laggard eddy current of going into powder-separating area under the rotation of cage rotor, the eddy current air-flow of material is carried in formation secretly, in the air-flow material powder of different-grain diameter under the acting in conjunction of suction force, centrifugal force, gravity by sorting, the fine powder of material is crossed cage rotor with air communication and is discharged from discharge pipe, and the dust-precipitator that enters peripheral hardware is collected and gets off to be finished product.The coarse dispersion of material lands from top to down or is thrown to inwall in separating chamber and drops to ash bucket again, discharges from the discharging opening of ash bucket bottom.Because powder freely feeds from powder inlet pipe, when falling on the spreading disk of cage rotor, powder can not get abundant boiling, and this zone powder density differs very big everywhere, makes the grinding efficiency reduction of powder concentrator.
The utility model content
The technical problems to be solved in the utility model provides circulation powder concentrator in a kind of K type, and it can make the process of powder from the powder inlet pipe free-falling to spreading disk fully boiling, suspended dispersed, makes this zone powder density even.
