Abstract
The utility model provides a degglomerator thick-fine powder air flow separation device which comprises a degglomerator thick powder material-returning chute. A shell is arranged between the degglomerator thick powder material-returning chute and a steady flow bin and is of a closed V shape. A feed inlet of the shell is connected with a discharge outlet of the degglomerator thick powder material-returning chute. The left side and the right side in the shell are respectively provided with two sets of inclined guide plates. The two guide plate positions on the right side are provided with blast pipes respectively. Thin holes are evenly formed in the blast pipes. The blast pipes are connected with a centrifugal fan. The bottom of the shell is provided with a thick powder discharge outlet which is connected with a roller press. A thin powder discharge outlet is formed in the shell beside the guide plates on the left sides, and the thin powder discharge outlet is connected with a grinding head dust collector. By means of the degglomerator thick-fine powder air flow separation device, the thick powder of the degglomerator is further sorted, circulating load of the roller press is reduced, and the squeezing effect of the roller press is improved.
Description
Technical field
The utility model relates to sorting unit, is specifically related to a kind of beater thickness powder air-classifier.
Background technology
Open circuit grinding system in cement grinding system is formed by roll squeezer, tube mill, two air-box type dust-precipitators.In the process of using, usually, because beater separating effect is undesirable, in meal feed back, fine powder is on the high side, cause roll squeezer unstable, therefore squeezing effect is poor, is restricting mill hourly output always, reduces the task of top priority that fine powder in beater meal feed back has just become cement production enterprise.
Summary of the invention
Technical problem to be solved in the utility model be how to the powder of beater sorting carry out slightly, fine powder sorting, thereby prevent from containing too much fine powder in meal, reduce the circulating load of roll squeezer.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of beater thickness powder air-classifier, comprise beater meal feed back scraper-trough conveyer, between described beater meal feed back scraper-trough conveyer and current stabilization storehouse, establish housing, housing is airtight V-type, the charging aperture of housing is connected with the discharging opening of beater meal feed back scraper-trough conveyer, left in housing, two groups of deflectors that tilt are respectively established in right both sides, on right side, two air deflector are established respectively ajutage, on every ajutage, evenly establish pore, ajutage is connected with centrifugal blower, at housing bottom, establish meal discharging opening, meal discharging opening is connected with roll squeezer, on the other housing of left side deflector, establish fine powder discharging opening, fine powder discharging opening is connected with bistrique dust-precipitator.
The utility model adopts the designed beater thickness powder air-classifier of technique scheme, owing to establishing airtight V-type housing between beater meal feed back scraper-trough conveyer and current stabilization storehouse, in housing, arranged on left and right sides is respectively established two groups of deflectors that tilt, right side two air deflector are established respectively the ajutage being connected with centrifugal blower, establish pore on ajutage.The end reciprocating collision of the material deflector that arranged on left and right sides is in tilted layout in housing, obtain further breaing up and dissociating, whole powder-separating area forms an equal refining curtain falling continuously, the sorting gas that ajutage is introduced passes this dropping material curtain with certain speed by deflector, after contacting cmpletely with material curtain, by deflector, the semi-finished product fine powder in material curtain is selected to housing, enter bistrique dust-precipitator directly into mill, the meal not being sorted returns to roll squeezer through meal discharging opening.The utility model, to the further sorting of the meal of beater, has reduced the circulating load of roll squeezer, has improved the squeezing effect of roll squeezer.
Accompanying drawing explanation
Fig. 1 represents the structural representation of the utility model beater thickness powder air-classifier.
The specific embodiment
Below in conjunction with accompanying drawing, the structure of the utility model beater thickness powder air-classifier is illustrated.
Referring to Fig. 1, the structure of the utility model beater thickness powder air-classifier comprises beater 1, the fine powder discharge nozzle 9 of beater 1, the meal feed back scraper-trough conveyer 2 of beater 1, between meal feed back scraper-trough conveyer 2 and current stabilization storehouse (not shown), establish housing 8, housing 8 is airtight V-type, the charging aperture 3 of housing 8 is connected with the discharging opening of meal feed back scraper-trough conveyer 2, in the interior left side of housing 8, establish two groups of deflectors 7, on the interior right side of housing 8, establish two groups of deflectors 4, two groups of deflector 4 places on right side establish respectively ajutage 5, on ajutage 5, be evenly provided with ventilation pore, ajutage 5 is connected with centrifugal blower (not shown), in the bottom of housing 8, establish meal discharging opening 6, meal discharging opening 6 is connected with roll squeezer (not shown), on the other housing 8 of left side deflector 7, establish fine powder discharging opening 10, fine powder discharging opening 10 is connected with bistrique dust-precipitator (not shown), said structure forms thickness powder air-classifier of the present utility model.
The operation principle of the utility model beater thickness powder air-classifier is: the meal of beater 1 after sorting for the first time enters the interior powder-separating area of housing 8 through charging aperture 3, the deflector 4 that material is in tilted layout in the interior arranged on left and right sides of housing 8,7 end reciprocating collision, obtain further breaing up and dissociating, on the height of whole powder-separating area and width, form an equal refining curtain falling continuously, referring in figure shown in arrow.The deflector that the sorting gas of being introduced by ajutage 5 one sides passes through ajutage 5 sides with certain speed passes this dropping material curtain, after contacting cmpletely with material curtain, by the deflector 7 of ajutage 5 sides, fine powder discharging opening 10 is selected and passed through to semi-finished product fine powder in material curtain and take housing 8 out of, enter bistrique dust-precipitator directly into mill.The meal not being sorted returns to roll squeezer through meal discharging opening 6.Test shows, the air quantity in ajutage 5 at least needs 12723 m
3/ h, sorting best results when wind speed is 18m/s.
The utility model is on probation through manufacturing experimently, and by air-classifier, to the further sorting of the meal of beater, has reduced the circulating load of roll squeezer, has improved the squeezing effect of roll squeezer, and average unit-hour output is improved, and power consumption has also reduced, remarkable in economical benefits.
