Background technology
Powder concentrator is an indispensable important classifying equipoment in cement and other mineral closed-circuit grinding system, having developed into horizontal vortex rotor at present is the classification epoch of fineness feature, have classification efficiency, effectiveness of classification height, characteristics such as particle is easy to adjust, but big, the higher special finished product collecting device of dust-collecting efficiency of palpus configuration process amount increases technological process and equipment investment in whole grinding system.As: O-SEPA high-performance powder concentrator commonly used has grading function preferably, enters efficient bag dust arrester installation after the classification again.Therefore, existing powder concentrator only has grading function.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of novel horizontal eddy current powder concentrator that grading function and collecting function are combined.
Novel horizontal eddy current powder concentrator of the present utility model, comprise the vortex rotor of band swirl vane in separating chamber's housing, the housing, the transmission device of driving rotor, have air inlet on separating chamber's housing, the top is provided with spout, separating chamber and rotor bottom connect the meal hopper, the top is the dusty gas air outlet, it is characterized in that the dusty gas air outlet connects rotoclone collector.
The utility model is the collecting function that increases fine powder on the basis of existing horizontal eddy current powder concentrator.The most frequently used frame mode of existing eddy current powder concentrator is an O-SEPA high-performance powder concentrator.
Rotoclone collector can adopt existing various technical pattern mode, and its effect is with the fines collection in the dusty gas.The dusty gas air outlet can external a plurality of discharge pipes, and each discharge pipe all connects rotoclone collector.Outer general optionally connected 1～3 discharge pipe of dusty gas air outlet.
Each discharge pipe is preferably taken over by 2 forks and is formed, and each fork is taken over and connected 1 rotoclone collector.From rationally utilizing the space, a plurality of discharge pipes should be evenly distributed on housing around.
As mentioned above, the existing a kind of more specific structure that only has the horizontal eddy current powder concentrator of grading function is that rotor top has spreading disk, and guide vane and buffer board are housed in the housing.In order to reduce the resistance to material, it is cydariform formula structure that the utility model can change present straight-plate-type structure to the swirl vane that has on the rotor.The last bottom surface of spreading disk can be provided with blade (original spreading disk only has blade at end face), and lower blade is longer than upper blade, and spreading disk can improve material dispersed effect and sealing effectiveness like this.
Advantage of the present utility model:
After increasing rotoclone collector, make horizontal eddy current powder concentrator not only have grading function, had collecting function simultaneously, shortened the technological process of whole grinding system, reduced equipment investment, reduced the maintenance in the production process, maintenance workload.The improvement of accessory structure wherein can improve the serviceability of equipment better.
