Description

Many classifications combined type powder concentrator
Technical field
The utility model relates to a kind of device that sub-elects qualified fine powder from the powder that thickness is mixed, and particularly uses the many classifications combined type powder concentrator in the cement production process.
Background technology
In cement production process, the efficient vortex powder concentrator is one of at present common powder selection device at present.Its operation principle 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 that falls, not through classification once more, these fine powders can not be separated from the meal powder in dropping process, thereby have effectiveness of classification and the low shortcoming of grinding efficiency.
The utility model content
The technical problems to be solved in the utility model provides a kind of many classifications combined type powder concentrator, and this powder concentrator can improve effectiveness of classification and grinding efficiency effectively in the manufacture of cement grinding process.
For solving the problems of the technologies described above, the utility model contains 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.
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.
Accompanying drawing is a structural representation of the present utility model.
1. powder inlet pipes in the accompanying drawing, 2. discharge pipe, 3. transmission device, 4. cyclone collector, 5. guide vane, 6. striker plate, 7. cage rotor, 8. material take-off clone, 9. spiral shell slurry formula spreading disk, 10. material-dropping clone, 11. air inlet, 12. meal collection cones, 13. fines collection awl, 14. housings, 15. vertical shafts.
The specific embodiment
In the accompanying drawing, powder inlet pipe 1 is arranged on the top of housing 14, and transmission device 3 is installed in the over top of housing 14, and vertical shaft 15 links with transmission device 3 and inserts in the housing 14.The lower end of vertical shaft 15 is provided with spiral shell slurry formula spreading disk 9, and the top of spiral shell slurry formula spreading disk 9 is provided with cage rotor 7, and the lateral surface of cage rotor 7 is provided with between the medial surface of the lateral surface of guide vane 5, cage rotor 7 and guide vane 5 gapped.Top is provided with striker plate 6 between the medial surface of the lateral surface of cage rotor 7 and guide vane 5.The below of spiral shell slurry formula spreading disk 9 is provided with material-dropping clone 10.The bottom of housing 14 is provided with air inlet 11, and the below of housing 14 is provided with meal collection cone 12, and the outside of meal collection cone 12 is provided with fines collection awl 13.The top of thin thick collection cone 13 is provided with cyclone collector 4, and the top of the top of cyclone collector 4 and housing 14 links, and the top of cyclone collector 4 is provided with discharge pipe 2, and discharge pipe 2 links with the top of cyclone collector 4.During work, the circulated air that enters from blast pipe 11 enters grading room through guide vane 5 and forms and select the powder air-flow, because the cage rotor 7 of rotation acts on and forms eddy current in the powder-separating area, selected powder enters the inside of powder concentrator by top powder inlet pipe 1, falling into cage rotor 7 tops powder under the rotation of cage rotor 7 is disperseed, to around dish out, the powder of being dished out is stopped in the eddy current that makes powder enter powder-separating area by striker plate 6, the swirl gas of material is carried in formation secretly, the powder of different-grain diameter is in suction force in the air-flow, centrifugal force, the acting in conjunction of gravity is passed through cage rotor 7 down by sorting, is entered cyclone collector 4 by the qualified fine powder of sorting with air-flow and is collected.Be entrained with the meal of fine powder, fall after landing from top to down or quilt are thrown to guide vane 5 and its collision in separating chamber, drop on the spiral shell slurry formula spreading disk 9 through material take-off clone 8, propeller formula spreading disk 9 rotates with vertical shaft 15, 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 guide vane 5 and select the powder air-flow, under the effect of cage rotor 7, in powder-separating area, form eddy current, the powder of different-grain diameter is in suction force in the air-flow, centrifugal force, by sorting, qualified fine powder enters cyclone collector 4 with air-flow and is collected under the acting in conjunction of gravity.These contain the meal that accompanies fine powder through once more sorting, fully remove the fine powder that is mixed in the meal, improve the effectiveness of classification and the grinding efficiency of powder concentrator effectively.The meal powder falls naturally greater than other external force because of self gravitation or is thrown to the limit wall and drops in the meal collection cone 12 again.
