Detailed description of the invention
The embodiment combined in accompanying drawing is further described by the present invention below:
As it is shown in figure 1, the invention mainly comprises ball milling staving 1, the two ends of ball milling staving 1 connect a hollow rotating shaft 2, connecting shaft bearing 3 on the hollow rotating shaft 2 at ball milling staving 1 two ends respectively, and bearing block 3 is fixed in ball milling frame 4.
The hollow rotating shaft 2 of ball milling staving 1 drive end is provided with travelling gear 5, and travelling gear 5 engages with the driving gear 7 of reductor 6 outfan and is connected.Described travelling gear 5 outer ring is provided with protective cover 8, protects travelling gear 5 by protective cover 8.
Being respectively equipped with helical blade 9 in the hollow rotating shaft 2 at ball milling staving 1 two ends, when ball milling staving 1 rotates clockwise, helical blade 9 can stop that the abrasive material in ball milling staving 1 enters in hollow rotating shaft 2；When ball milling staving 1 rotates counterclockwise, the abrasive material in grinding barrel body 1 can enter in helical blade 9 under the gas with pressure blows.
Hollow rotating shaft 2 outer end at ball milling staving 1 two ends connects air valve 11 by rotatory sealing 10 respectively, can be controlled closedown and the unlatching of hollow rotating shaft 2 internal channel by air valve 11.
As in figure 2 it is shown, ball milling staving 1 two ends are provided with guide cone circle 13, being provided with multiple spiral spoiler 14 in guide cone circle 13, multiple spoilers 14 are circumferentially uniformly distributed.Because during ball milling, material can enter in guide cone circle and hollow rotating shaft by pellet separating plate, Gu Daoxiangzhuiquan is mounted with spoiler, stops material to enter in hollow rotating shaft.
As it is shown on figure 3, be provided with pellet separating plate 12 inside ball milling staving 1 two ends, pellet separating plate 12 is provided with multiple equally distributed separating tank.The inwall of ball milling staving 1 is provided with ball milling liner 15, and ball milling liner 15 is provided with multiple baffle plate 16, and multiple baffle plates 16 are uniformly distributed along ball milling staving 1 circumferencial direction.Multiple baffle plate 16 is set in ball milling staving 1 spheroid can be mentioned higher height, increase spheroid and clash into the dynamics of material, thus improve the efficiency of ball milling.
It is setting up and down that described ball milling staving 1 is provided with charging aperture 17 and service hatch 18, charging aperture 17 and service hatch 18.
The operation principle of the present invention is: when ball milling works, and material adds ball milling bucket by the charge door of ball milling staving, and ball milling staving two ends air valve is closed, and ball milling staving is made 360 ° of continuous rotary motions vertically and carried out ball milling operation.Owing to ball milling inner wall of barrel is mounted with baffle plate, spheroid can be mentioned higher height, increase spheroid and clash into the dynamics of material, thus improve the efficiency of ball milling.Because during ball milling, material can enter in guide cone circle and quill shaft by pellet separating plate, Gu Daoxiangzhuiquan is mounted with spoiler, hollow rotating shaft there are also installed helical blade, when ball milling bucket rotates forward, spoiler and helical-blade sector-meeting produce one thrust in ball milling bucket, material is returned in ball milling bucket, so ball milling dead angle will not be produced by thrust through pellet separating plate；During discharging, air valve is opened, and ball milling staving is contrary with direction of rotation during ball milling, the suction produced by high pressure positive blower, makes whole unit produce negative pressure state.Air outside ball milling staving is due to pressure reduction, entered in ball milling staving by ball milling staving one end hollow rotating shaft, the powder of milled in ball milling staving is taken out of entrance cleaner unit from the other end, powder moves to cleaner unit bin bottom due to gravity, being discharged by Star-like unloader, gas is discharged by blower fan mouth through the filtration of filter bag, owing to blower fan is work continuously, ball milling bucket is the most ceaselessly to rotate simultaneously, and the powder in ball milling bucket all goes out to the greatest extent the most at last；Further, since eminence mentioned by material by baffle plate during discharging, produce airborne dust and easily taken out of by air-flow, accelerate discharging speed, and go out the cleanest；It is simultaneously directed to the spoiler that cone circle is installed, make air enter ball milling staving and produce revolving dispersion, in driving ball milling bucket, material rapidly flows toward the ball milling bucket other end, after material enters the guide cone circle of the other end, accelerate flow direction of material quill shaft by proposing effect on spoiler, thus improve discharging efficiency.
The present invention improves the work efficiency of discharging and ball milling, easy to operate, rationally distributed, reduce labor intensity, by blower negative pressure sucking-off powder, discharging speed is fast and clean, it is to avoid powder goes out the most totally to cause the cross-contamination of different batches product；Spoiler and helical blade stop material to enter in hollow rotating shaft；Mill inner wall of barrel is mounted with baffle plate, and spheroid can be mentioned higher height, increases spheroid and clashes into the dynamics of material, thus improves the efficiency of ball milling；Pellet separating plate is directly installed in ball milling bucket, all without exchanging for when ball milling and discharging, and easy to operate, minimizing labor strength.
