Adopting high-efficient powder concentrator to improve grinding efficiency, reduce system energy consumption, is one of efficient ways commonly used that improves the grinding machine capacity usage ratio, but along with to the improving constantly of cement quality requirements, the defective that its grinding efficiency is low comes out gradually; The high thin powder concentrator of cement highly efficient is for adapting to cement new-standard, and the cement plant is more and more higher to the requirement of cement fineness, and many producers have changed the specific area of control cement into to the control of fineness.Studies have shown that in recent years, the particle between 3～30 microns is the most favourable to strength of cement, and common rotor powder concentrator majority can't reach this requirement, and also common powder concentrator floor space is big, and complex structure uses inconvenience, and operating efficiency is not high.
The utility model content:
The purpose of this utility model provides a kind of efficient birotor powder concentrator, and it is simple in structure, and floor space is little, and the machine system power consumption is low, and can reach the requirement of cement plant to cement fineness, can improve grinding efficiency, improves the grinding machine capacity usage ratio.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it is by buncher 1, rotor 2, housing 4, whirlwind tube 7, hopper 8, dropping system 9, first leg 10, second leg 11, first discharge pipe 16, second discharge pipe 18 and motor leg 19 are formed, the lower end of buncher 1 is provided with motor leg 19, motor leg 19 is connected with rotor 2, rotor 2 is arranged on the inside center position of hopper 8, the outer setting of hopper 8 has housing 4, dropping system 9 is arranged on the lower end of hopper 8, the lower end of dropping system 9 is fixing with lower end powder gathering-device 20 by first leg 10 and second leg 11, the outside of housing 4 evenly is provided with several whirlwind tubes 7, whirlwind tube 7 upper ends are provided with first discharge pipe, 16, the first discharge pipes 16 and are connected with second discharge pipe 18.
Described motor leg 19 and rotor 2 by V be with 13, small belt pulley 14 is connected with key 15.
Described whirlwind tube 7 lower end arranged outside have inspection door 12.
Described powder gathering-device 20 is made up of fines collection device 20-1 and meal gathering-device 20-2, fines collection device 20-1 is arranged on the upper end of meal gathering-device 20-2, fines collection device 20-1 is provided with fine powder outlet 20-3, and meal gathering-device 20-2 lower end is provided with meal outlet 20-4.
Operation principle of the present utility model is: material enters from hopper 8, fall on the spreading disk through rotor 2 intermediate feed pipes, swirling eddy continues rotation and rises after 9 pairs of powders of three layers of dropping system clean, under following cage rotor effect, powder is by first sorting.Fine powder continues to rise with air-flow, the powder that leaves with propeller formula spreading disk carries out sorting do relative motion and cleans, last qualified fine powder enters whirlwind tube 7 with air-flow and collects, enter from whirlwind tube 7 lower ends in the fines collection device 20-1 of powder gathering-device 20,20-3 discharges from the fine powder outlet, is finished product; Meal is discharged from the meal outlet 20-4 of meal gathering-device 20-2 lower end.
In the utility model, product fineness is mainly controlled by the rotating speed of regulating rotor 2.Rotor 2 rotating speeds increase, and fineness attenuates; Rotor 2 speed diminish, the fineness chap.Regulate air quantity and also can reach the purpose of controlling fineness, easy to use, the grinding efficiency height.
The utility model is simple in structure, and floor space is little, and the machine system power consumption is low, and can reach the requirement of cement plant to cement fineness, can improve grinding efficiency, improves the grinding machine capacity usage ratio.
