Description
Technical field
The present invention relates to a kind of screening installation of powder, the multistage powder concentrator of particularly a kind of carse, medium and small powder.
Background technology
At present, powder concentrator is widely used in the powder manufacturings such as manufacture of cement.Existing traditional centrifugal, cyclone type of existing powder concentrator and rotator type powder concentrator also have the good relatively O-Sepa powder concentrator of performance that comes out in recent years.Existing O-Sepa powder concentrator, its working mechanism is: the material through preliminary grinding feeds powder concentrator by the top charging aperture, fully disperses by spreading disk, buffer board, falls into powder-separating area.Wind by the air inlet of separating chamber both sides, enters powder-separating area through guide vane respectively.The cage rotor of in powder concentrator, forming by vertical vane and horizontal blade, make during revolution that whole powder-separating area inside and outside differential pressure is kept up and down necessarily, steady air current is even, the chance that repeatedly repeats sorting is provided for top-down material, qualified fine powder is extracted out from top by central tube with air-flow, enters follow-up dust-precipitator fines collection is got off; Meal returns grinding machine grinding once more from the cone bottom, form the circle streaming system.Though O-Sepa powder concentrator unit interval treating capacity is big, effectiveness of classification is high, energy-saving and cost-reducing and be widely used, but because the O-Sepa powder concentrator can only carry out classification to the micron order powder material by its rotor, thereby can't satisfy the demand that the sandstone classification is produced, can't with the sandstone finished product by particle diameter＞2mm, 2～0.1mm and＜three kinds of specifications of 0.1mm realize carse, medium and small three ranking score levels; And, because sandstone coarse granule particle diameter is bigger, also can cause the O-Sepa rotor of powder separator to damage easily, can not run well.At present, in sandstone classification production process, still adopt traditional vibratory sieve, yet vibratory sieve can only be classification face with 2mm usually, can't realize multipass sort, make the particle of 2mm be waste product, cause great waste of raw materials, and production efficiency is low, operation and maintenance cost height, dust are difficult to control, heavy contamination.
Summary of the invention
Technical problem to be solved by this invention is, at the deficiencies in the prior art, a kind of rational in infrastructure, manufacturing cost is provided and operation and maintenance cost is low, classification often, the multistage powder concentrator of effectiveness of classification and output, high efficiency.
The technical solution adopted for the present invention to solve the technical problems is: comprise housing, motor, rotor, wind blade, whirlwind tube, feed pipe and wind converging tube; Rotor is loaded on the top of housing and links to each other with motor, and the periphery of rotor is provided with wind blade, and the below of rotor is provided with material-falling hopper, and the end opening of material-falling hopper is provided with air valve; The periphery of housing is provided with several whirlwind tubes, and the suitable for reading of whirlwind tube interlinks with housing and wind converging tube respectively, and the end opening of whirlwind tube is provided with discharge valve; It is characterized in that: the end opening of housing is provided with feed pipe, is equipped with blanking barrel in the outside of feed pipe, and the end opening of blanking barrel is provided with air valve; On the outer wall of the material-falling hopper above the blanking barrel, be provided with the whole deflector that several piece is provided with in the shape of a spiral.During work, treat that the material of sorting enters in the powder concentrator from the feed pipe of housing below with the wind, the material of larger particles forms fluid bed, falls in the blanking barrel behind the bump cowling panel and discharges through air valve, realizes the one-level sorting; The cowling panel one side is the material of sedimentation larger particles effectively, reduces the resistance of equipment air inlet, can carry out rectification to air-flow on the other hand, makes the particle composition of material narrower, has reduced oarse-grained interference, helps fine granular materials and is sorted out fully.Air-flow rotates the middle and upper part that rises to housing after rectification, through wind blade once more after the rectification, carry out sorting once more by rotor, thicker material falls in the material-falling hopper, discharge the sorting of realization secondary by air valve, thinner material then is assigned with and enters in each whirlwind tube, and the whirlwind tube utilizes the gravity of material self to carry out the sorting of material, and, realize the classification for the third time of material by the discharge valve discharge.Superfine material in the air-flow then enters in the follow-up cleaner by wind converging tube, and fine material is recycled, and realizes the 4th classification of material, has improved rate of energy simultaneously, has reduced the harm of superfine powder to human body and environment.
Above-mentioned whirlwind tube is a centering type whirlwind tube, and its volute angle is 270 °, can effectively reduce equipment resistance like this, increases the dust-collecting efficiency of finished product, and can reduce the input of follow-up cleaner.
The inner chamber of above-mentioned whirlwind tube is provided with the taper radiation shield that prevents reentrainment of dust, and the radiation shield periphery links to each other with the inwall of whirlwind tube by several connecting rods.
Beneficial effect of the present invention is: be specially adapted to the classification production of sandstone, it is rational in infrastructure, classification often, the effectiveness of classification height, manufacturing cost and operation and maintenance cost are low, good in economic efficiency, and can improve specific yield and operating efficiency effectively, reduce environmental pollution.
