Abstract
The present invention relates to a propeller type centrifugal powder selecting machine; a propeller material dispersing disc and an impact flow guiding plate are used, so the dispersivity of separating materials is better. The powder selecting efficiency is raised by 30 to 40% of that of a flat plate material dispersing disc type centrifugal powder selecting machine; the surface area of selected materials is enlarged about 20%. Under the condition of the same production scale, the weight of equipment can be reduced over 30%, the power consumption can be reduced by 12 to 14%, and the expense for manufacturing the equipment can be saved over 10 to 30%.
Description
The present invention relates to the screening installation of a kind of cement slurry and cement products.
Existing centrifugal powder concentrator is that its bed of material that spreads out is thick with the dull and stereotyped spreading disk sorting material of band cover, and bad dispersibility selects the powder benefit low, and power consumption is also high.
The object of the present invention is to provide a kind of sorting material good dispersion, grinding efficiency height, weight of equipment is light, power consumption is low centrifugal powder concentrator.
The mechanism of the technology of the present invention design is to strengthen the airflow acting force of rotation at a high speed, and incorporating mill tool centrifugal force combines to improve the dispersiveness of sorting material.
The concrete technical scheme of the present invention is to have invented propeller scattering plate, to replace original dull and stereotyped spreading disk; The bump deflector has been set up in the inner barrel bottom; Aligned the quantity of large and small fan blade, to strengthen the air-flow effect of rotation at a high speed.
Propeller scattering plate of the present invention, it is made up of 12-16 sheet blade, and blade becomes 12～20 ° of angles to be set on the main shaft with horizontal plane.When propeller scattering plate is turned clockwise by the main shaft drive, both produced centrifugal force, has the spreading effect, produced spiralling air-flow again, material particles boiling fully on the spreading disk is kicked up, so the bed of material that the more dull and more stereotyped spreading disk of thickness of its bed of material that spreads out spreads out is thinner, and material dispersed is better.Spiral shell slurry dish is in rotary course simultaneously, and each dihedral vane also plays the strike effect to the material under spreading, and the bulk material particles can be smashed again, increases dispersion efficiency.The fine granular materials that has disperseed the air-flow that big blade rotates formation at a high speed drive dirty inwardly, annular space between outer cylinder body, heavy at last to the fine powder material pipe; Separate the coarse granule material of shape, because the resistance that its weight rises greater than circulating current, and sink to the meal material pipe of inner barrel foot.
Bump deflector of the present invention is to be welded on inner barrel cylinder and cone junction.Bump deflector itself is the structure at 120 ° of inclination angles, during welded and installed and inner core body wall angle be 30 °.It is to rebounding with this plate face bump when the centrifugal stratiform material that spreads out is to inner tube wall on the spreading disk that the present invention adopts the effect of bump deflector, increase the mutual effect of impact of storeroom, further to smash the bulk material, impel in the bed of material fine granular materials to kick up once more, enter annular space between inside and outside cylindrical shell with ascending air once more, thereby improve grinding efficiency.The present invention is uniform installation 6-12 piece bump deflector in inner barrel.
The air-flow that the present invention makes progress for the high speed rotation that better forms in the cylindrical shell, the quantity of having aligned fan blade accordingly, the big blade that the present invention adopts is 16～24 and is distributed in the outer cylinder body top, adopts little fan blade to be 6～12 and be distributed in the inner barrel top.
Advantage of the present invention and effect: propeller type centrifugal powder selecting machine is owing to adopted propeller scattering plate, bump deflector and aligned large and small fan blade quantity, the material good dispersion that impels powder concentrator of the present invention to spread out, the separation β value of material (coarse granule and fine grained ratio) can reduce by 15～20%, therefore the circulating load of material only reaches half of centrifugal powder concentrator of dull and stereotyped spreading disc type, and grinding efficiency improves 30-40%.Improved product quality simultaneously, selected material specific surface area can improve about 20%.
Because the circulating load rate of material reduces greatly, the material flow flux also greatly reduces in the corresponding closed-circuit system grinding machine, and the thickness of the interior bed of material of mill is attenuate also, has therefore improved the ability of the pulverizing of grinding machine, and the output of grinding machine can improve 15-20% again.
Propeller type centrifugal powder selecting machine is owing to the raising of dispersibility, and therefore under the identical condition of production scale, the specification of powder concentrator can correspondingly reduce, and weight of equipment can alleviate 30% more than, and power consumption can reduce 12-14%, and the device fabrication expense can be saved more than the 10-30%.
Describe the present invention below in conjunction with accompanying drawing:
Accompanying drawing 1 is propeller type centrifugal powder selecting machine structural representation (drive motor omits among the figure).
Accompanying drawing 2 is propeller scattering plate structural representations.
Accompanying drawing 3 is bump deflector and propeller scattering plate top view.
Accompanying drawing 4 is that large and small fan blade is installed, structure chart.
Propeller type centrifugal powder selecting machine shown in the accompanying drawing 1 of the present invention, its outer cylinder body 10 and inner barrel 7 are suit enclosed constructions, and two cylindrical shell tops all are cylindrical structure, and the bottom all is a conical structure, the outer cylinder body foot is a fine powder material pipe 15, and the inner barrel foot is a meal material pipe 14; Fix and formed annular space with support 5 in the middle of two cylindrical shells, the tube top is by upper cover plate 17 sealings; Inside and outside cylindrical shell top is hollow hopper 18 between two parties, and powder hopper is thus sent in the powder concentrator; The cone of inner barrel 7 bottoms is connected with return air blade 12, and the gap between the return air blade is the passage of inside and outside cylindrical shell air-flow circulation; Vertical major 3 runs through the center of hollow hopper 18, and extends in the inner barrel (7), and main shaft 3 is connected through the vertical type speed reducer (change gear) 1 of yielding coupling 2 with the tube top.The mutual rigidity of large and small as shown in Figure 4 fan blade links and is welded on main shaft 3 axle sleeves, 16 big blade 4 levels are distributed in the outer cylinder body top, 6 little fan blade 6 levels are distributed in the inner barrel top, and it is the propeller scattering plate 9 that 14 ° blade assembles with the horizontal plane inclination angle that main shaft 3 terminals are equipped with by 12; Inner barrel cylinder and cone junction are welded with uniform 12 bump deflectors 8, and bump deflector itself is 120 ° of inclination angles, with the inner tube wall angle be 30 °.
The propeller type centrifugal powder selecting machine of forming by above-mentioned member, when main shaft 3 turns clockwise, rely on the high speed of the big blade 4 on outer cylinder body top to rotate the ascending air that forms, and the gas channel of return air blade 12, the outer cylinder body circulating current enters inner core and forms the air-flow that rises, propeller scattering plate 9 and the boiling that causes of bump deflector 8 ascending air of kicking up in addition, fine-grained powder upwards enters annular space between inside and outside cylindrical shell with air-flow, and is heavy at last to fine powder material pipe 15.Because the circulating current barrier that little fan blade 6 forms when rotated in the inner barrel blocks the coarse granule powder upwards, and because the resistance that the weight of coarse granule powder makes progress greater than circulating current, and sink to meal material pipe 14.
