Abstract

Propeller type centrifugal powder selecting machine is owing to adopt propeller scattering plate and the bump deflector, can make the dispersed better of sorting material, grinding efficiency improves 30-40% than the centrifugal powder concentrator of dull and stereotyped spreading disc type, the surface area of selected material improves about 20%: under the identical condition of production scale, weight of equipment can alleviate 30% more than, power consumption can reduce by 12-14%, and the device fabrication expense can be saved more than 10-30%.

Description

The present invention relates to the screening installation of a kind of cement slurry and cement products.
Existing centrifugal powder concentrator is with the fineness of auxiliary fan blade and adjusting plate adjusting product, needs to shut down and carries out, and can not control product fineness automatically, and the dull and stereotyped spreading disk of existing band cover selects the powder benefit low, and power consumption is also high.
The object of the present invention is to provide a kind of grinding efficiency height, weight of equipment is light, the centrifugal powder concentrator that power consumption is low.
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 separation property 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.
The structure of propeller scattering plate 9 of the present invention as shown in Figure 2, it is made up of 12-16 sheet blade, blade becomes 12~20 ° of angles to be set on the main shaft 3 with horizontal plane.When propeller scattering plate is turned clockwise by the main shaft drive, both produced centrifugal force, has the spreading effect, the spiralling air-flow of Chan Shenging again, material particles boiling fully on the spreading disk is kicked up, therefore, the bed of material that the more dull and more stereotyped spreading disk of thickness of the residue bed of material that it spreads out is withdrawn from is thinner, and material dispersed is better.Spiral shell slurry dish is in rotary course simultaneously, and each dihedral vane also plays the strike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 separative efficiency.The fine granular materials that has separated big blade 4 at a high speed the air-flow that forms of rotation drive dirty inwardly, annular space between outer cylinder body, heavy at last to fine powder material pipe 15; The coarse granule material that separates shape because the resistance that its weight rises greater than circulating current, and sinks to the meal material pipe 14 of inner barrel 7 foots.
Bump deflector 8 of the present invention is cylinder and the cone junction that is welded on inner barrel 7 as shown in Figure 3.Bump deflector 8 itself is the structure at 120 ° of inclination angles, during welded and installed and the inner tube 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 8, mutual effect of impact between the increment bed of material, 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 present invention is in order better to form the high speed rotation air-flow upwards in the cylindrical shell, aligned the quantity of fan blade accordingly, the big blade 4 that adopts of the present invention is 16~24 and is distributed in the outer cylinder body top as shown in Figure 4, adopts little fan blade 6 to be 6~12 and is 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 9, bump deflector 8 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 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 because therefore the raising of separating power under the identical condition of production scale, selects the specification of extension set correspondingly to 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%.

Fig. 1: propeller type centrifugal powder selecting machine structural representation (drive motor omits among the figure).
Fig. 2. the propeller scattering plate structural representation.
Fig. 3. bump deflector and propeller scattering plate top view.
Fig. 4. large and small fan blade is installed, structure chart.
The embodiment of the invention, contrast Fig. 1 explanation:
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, and 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 extend in the cylindrical shell, main shaft 3 is connected through the vertical type speed reducer (change gear) 1 of yielding coupling 2 with the tube top, large and small as shown in Figure 4 fan blade is with being loaded on the main shaft 3,16 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 main shaft 3 terminals are equipped with the propeller scattering plate 9 that is assembled by 12 blades; 12 uniform bump deflectors 8 are equipped with in inner barrel cylinder and cone junction.
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 bump deflector 8 boiling poplar of causing play ascending air in addition, in fine-grained powder upwards enters with air-flow, annular space between outer cylinder body, 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, block the coarse granule powder upwards, and because the resistance that the weight of coarse granule powder makes progress greater than circulating current, and sinking to meal material pipe 14, structure has reached purpose of the present invention and task thus.
