Description
Technical field
The utility model relates to a kind of in the grinding process of nonmetallic ore processing, with the rotor of powder separator that powder granule carries out classification by its particle size, and particularly a kind of ultra-fine powder concentrator cage rotor.
Background technology
In cement production, slag production, slag is worn in the operations such as agstone of micro mist, electric field desulfurization use at present, most common form is to adopt the main process equipment grinding earlier, sub-elect finished product by powder concentrator then, thick particle returns and carries out grinding in the main frame.
Ultra-fine powder concentrator is can handle big inventory and have the grader that height selects the powder precision.It contains transmission system, housing, feed arrangement, cage rotor, meal collection cone, air-intake device, cleaning device.Its basic functional principle is: material is fallen on the spreading disk of cage rotor by feed arrangement, along with the rotation material of cage rotor evenly spread to around, form the suspended dispersed state, and carry out preliminary dispersion and separate, because the effect of gravity, material is in dispersity falls into branch constituency between wind-guiding leaf and the cage rotor, under the acting in conjunction of sorting air-flow and cage rotor rotation, powder granule will be subjected to gravity simultaneously, wind-force and action of centrifugal force, when than the suffered stream pressure of the material of granule during greater than centrifugal force, will enter in the rotor with air-flow, the air outlet on housing enters follow-up gathering-device, and finished product materials is separated.
In the powder concentrator use, classification performance is one of most important characteristic of estimating the powder concentrator quality, in cage rotor, play grading be horizontal blade and with the graded blade of divider upright, the powder concentrator cage rotor is the core of powder concentrator.Material is behind the feeding powder concentrator, fall on the spreading disk that is installed on the powder concentrator cage rotor, under the high speed turning effort of spreading disk, material is thrown out of, in dropping process, collide on the wind-guiding leaf that is installed on the housing, then at centrifugal force, under the triple role of wind-force and gravity, material is subjected to repeatedly sorting in powder-separating area, but centrifugal force and wind-force are not well-proportioned, the particle that has is subjected to wind-force big, the particle that has is colliding mutually or is being subjected to the effect of forced vortex can produce bigger centrifugal force again, be subjected to the big particle of centrifugal force in the process that gravitate moves downward, collide the wind-guiding leaf that is installed on the housing, the wind-guiding leaf be rigidity and be in vibrating state at work, collide particle on the wind-guiding leaf under the effect of centrifugal force and wind-force, move to epitrochanterian graded blade fast.It mainly is because collision and being installed in due to the rebound effect of the wind-guiding leaf on the housing between particle that bulky grain is sneaked into finished product.Previously usedly be mounted to actinomorphic cage rotor blade, the projection interval on the cage rotor face of cylinder is very big, and bulky grain is easy to enter the finished product district when being subjected to the rebound effect of wind-guiding leaf.Another design in the past---adopt the droplet-shaped rotor blade, it is high especially to make requirement, arranges to be still and continues to use the radial pattern structure, and in use do not play the effect of getting instant result, grading precision and classification efficiency still are not ideal enough.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of ultra-fine rotor of powder separator, by changing the setting angle of blade, can prevent effectively that bulky grain from sneaking into phenomenon, improves grading precision and classification efficiency.
For solving the problems of the technologies described above, the ultra-fine powder concentrator cage rotor of the utility model comprises upper spacer, spreading disk, sealing ring, brace, Drag link, axle sleeve, support column, graded blade, median septum, cone seat, lower clapboard.Constitute the rotor skeleton by cone seat, brace and Drag link etc., the top of rotor skeleton a circular spreading disk is arranged and be used for and housing between the sealing ring that seals, the internal diameter of sealing ring equals the diameter of air outlet; Lower clapboard is installed below the skeleton, at the graded blade that is equipped with on along the circumferential direction between lower clapboard and the spreading disk perpendicular to lower clapboard, graded blade and axle center are included angle A (as shown in the figure), consider the requirement that intensity and horizontal gas flow produce between the blade, be horizontally installed with median septum, the external diameter of upper, middle and lower dividing plate is all identical, and the cylindrical of graded blade and the space that the dividing plate cylindrical has 30～60mm are installed.In cage rotor skeleton centre the axle sleeve that is used to connect driving is installed, axle sleeve is justified coaxial with upper, middle and lower dividing plate, graded blade.Be provided with support column between upper spacer and the lower clapboard.
The utility model becomes certain inclination angle with graded blade with the axle center, angle is 5～30 °.In the running, bulky grain collides graded blade after bounce-back can skid off rotor along the blade that tilts, and has solved the phenomenon that the coarse granule recoil enters the finished product district.Graded blade and horizontal baffle produce when rotated stablizes strong forced vortex, has improved grinding efficiency, has reduced the bypass value of powder concentrator.
The utility model is simple in structure, and is easy to make, and effect is remarkable, can effectively prevent coarse grained doping, guarantees that end product quality is stable, effectiveness of classification and classification efficiency excellence.
