Below in conjunction with the drawings and specific embodiments, detailed construction of the present invention is further described.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in drawings: a kind of powder grinder, comprise cylindrical shell 1, screen cloth 3, grinding assembly 5, medium ball 13, cylindrical shell 1 is the vertical structure of end sealing, cylindrical shell 1 is divided into the finished bin of superstructure and the grinding storehouse of understructure by screen cloth 3, screen cloth 3 bottom surface is provided with tapered sleeve 7, and medium ball 13 is dispersed in grinding storehouse; Grinding assembly 5 comprises grinding shaft 14, grinding blade 15, driving mechanism 4, grinding shaft 14 is through screen cloth 3, grinding blade 15 be arranged on be in grinding storehouse in grinding shaft 14 on, driving mechanism 4 is connected with grinding shaft 14, driving mechanism 4 is made up of drive motors, driving mechanism 4 rotates for driving grinding shaft 14, and grinding shaft 14, through tapered sleeve 7, the grinding shaft 14 above grinding blade 15 is also provided with the centrifugal mechanism 10 for playing centrifugal action to the medium ball in grinding; Cylindrical shell 1 is provided with and the charging aperture 17 grinding storehouse and be communicated with, and charging aperture 17 place is provided with screen pack 16, and screen pack 16 can prevent medium ball 13 from process of lapping, entering into charging aperture 17; Cylindrical shell 1 is also provided with the discharging opening 9 be communicated with finished bin.
The larger end of opening of tapered sleeve 7 is connected with screen cloth 3, and the opening of tapered sleeve 7 is in the top of centrifugal mechanism 10 compared with small end.
Cylindrical shell 1 inwall is provided with mounting flange 2, and screen cloth 3 is detachably arranged on mounting flange 2, the setting of mounting flange 2, and being convenient to screen cloth 3 can change according to different demands; Screen cloth 3 is made up of a radiant type screen cloth 8 and a three-dimensional screen cloth 6, radiant type screen cloth 8 horizontal positioned, three-dimensional screen cloth 6 is together with radiant type screen cloth 8 at right angle setting, and grinding shaft 14 passes from the center of three-dimensional screen cloth 6, and three-dimensional screen cloth 6 is between finished bin and grinding storehouse; The dictyosome of three-dimensional screen cloth 6 is the three-dimensional screen cloth body of fence.
Centrifugal mechanism 10 comprises the centrifugal pan 12 be arranged on grinding shaft 14, is positioned on centrifugal pan 12 and the centrifuge blade 11 distributed along centrifugal pan 12 even circumferential, grinding shaft 14 passes from the center of centrifugal pan 12, when grinding shaft 14 rotates in the process driving centrifugal pan 12 to rotate, the centrifuge blade 11 be arranged on centrifugal pan 12 can stir medium ball 13, and medium ball 13 is moved along the direction of cylindrical shell 1 inwall under the influence of centrifugal force.
Operation principle of the present invention and using method are: powder is in the process of grinding, powder material and solvent mix and blend are formed powder original slurry material, powder original slurry material is ground in grinding storehouse, in the process of grinding, the grinding shaft 14 of grinding assembly 5 rotates under the effect of driving mechanism 4, in rotation process, grinding blade 15 stirs powder original slurry material, the medium ball 13 in grinding storehouse is driven to move together, in the process of motion, realize grinding the powder material in powder original slurry material by the friction between medium ball 13 and shock, after powder in powdery pulp reaches default fineness, be filtered in finished bin from screen cloth 3 under the effect of ambient pressure, finally be delivered to discharging opening 9 place, in the process, when the medium ball in slurry along with slurry near screen cloth 3 time, be centrifuged under the effect of the centrifuge blade 11 of medium ball in centrifugal mechanism 10, away from the less end opening of tapered sleeve 7, and now slurry enters in tapered sleeve 7 from the less end opening of tapered sleeve 7, then flowed out by the larger end opening of tapered sleeve 7, enter into finished bin, tapered sleeve 7 plays block media ball 13 in above process, the mating reaction of tapered sleeve 7 and centrifugal mechanism 10, the powder reaching default fineness is made to enter in finished bin by screen cloth 3 in time, compared with prior art, improve the efficiency of powder grinding.
Slurry (containing medium ball) in grinding storehouse is in rapid circular movement state, when by centrifugal pan 12, the medium ball 13 of more than 80% is separated with slurries under centrifugal action, after the medium ball of remainder enters tapered sleeve 7 with slurries, the kinetic energy of medium ball 13 reduces rapidly, when slurry is by radiant type screen cloth 8 and three-dimensional screen cloth 6, medium ball 13 is then separated completely with slurries.The action principle of centrifugal pan 12 is: the centrifugal force that fast rotational produces is by medium ball 13 larger for gravity and slurries quick separating; The effect of tapered sleeve 7 is clockwise atwirl dynamic slurry to be transformed into close to inactive state, is conducive to medium ball 13 and relies on Action of Gravity Field to sink, and also can reduce screen cloth 3 impulsive force simultaneously, avoids blocking screen cloth 3; The form adopting three-dimensional screen cloth 6 to combine with radiant type screen cloth 8, can improve sieve flow and the screening efficiency of slurries.Be in that medium ball 13 in tapered sleeve 7 is automatic to be under gravity separated with screen cloth 3, then sink down on centrifugal pan 13, then it be centrifugal to be centrifuged blade 12.
