Description
Technical field
The utility model relates to the energy-efficient combined type powder concentrator in the manufacture of cement industry.
Background technology
In the prior art, the powder concentrator that cement industry is used has old-fashioned cyclone type powder sorting machine, rotator type powder concentrator and horizontal eddy current powder concentrator etc.They all ubiquity that efficient is low, powder particles can not be regulated, the out of contior defective of air quantity.In recent years, the energy-efficient powder concentrator that powder particles and air quantity can be controlled occurs, and is used widely gradually, but still has some defectives, is particularly handling under the big and demanding situation of output of air quantity, and device geometry is very huge.
Summary of the invention
The purpose of this utility model provide a kind of compact conformation that overcomes the prior art defective, grinding efficiency height, fineness adjustment easily, the easy combined type powder concentrator of air quantity control.
The combined type powder concentrator, it is characterized in that: the top at device is provided with the charging scraper-trough conveyer, motor connects reductor by shaft coupling, reductor is connected with rotor shaft by shaft coupling, motor and reductor are fixed on the support, rotor tip is provided with spreading disk, and the spreading disk card is corresponding with charging scraper-trough conveyer end opening; Rotor exterior at upper shell is provided with guide vane, and the circumference of guide vane and rotor is angled, and guide vane is fixed on upper shell surface and the inner cone surface, is provided with the labyrinth circle in the spreading disk inboard; Lower house is the back taper housing, and its inside is provided with inner cone, and the cone of inner cone outside is called Outer Taper, is provided with the counterattack awl in the inner cone bottom, counterattack awl and looping gap, inner cone bottom, and the lower house bottom is provided with discharging and takes over; Upper shell top is air outlet, and air outlet connects the whirlwind tube, and the whirlwind tube connects deduster.
The utility model has the advantages that: output is big, operating mode is wide; Compact conformation, one-machine-multi-function; Energy-efficient, equipment resistance is little; Simple to operate, fineness is easy to adjust; It is little to wear and tear, and maintenance cost is low.
