The specific embodiment
Below in conjunction with technical scheme and accompanying drawing, describe the specific embodiment of the present invention in detail.
With reference to accompanying drawing 1, this grain size adjustable abrasive material screening machine comprises: wide-meshed screen 1, guide groove 2, coarse grained abrasive aggregate bin 3, flow distribution plate guide groove 4, buffer board 5, driving wheel 6, belt pulley 7, abrasive material aggregate bin 8, belt 9, drive motors 10, conveyer belt 11, broken abrasive material aggregate bin 12, driven pulley 13, finer abrasive aggregate bin 14, baffle plate A15, fine screen mesh 16, baffle plate B17.Wide-meshed screen 1 is positioned at the top of fine screen mesh 16, buffer board 5 is fixed on flow distribution plate guide groove 4 ends, conveyer belt 11 is positioned at buffer board 5 belows, coarse grained abrasive aggregate bin 3 is positioned at guide groove 2 belows, abrasive material aggregate bin 8 is positioned at conveyer belt 11 belows, lower end, broken abrasive material aggregate bin 12 is positioned at conveyer belt 11 belows, upper end, and finer abrasive aggregate bin 14 is positioned at baffle plate A15 below.
In use procedure, the compound abrasive particle of original state is entered by wide-meshed screen 1 upper end, and abrasive grain is by Action of Gravity Field, and the abrasive grain that granularity is greater than wide-meshed screen 1 mesh size falls along the wide-meshed screen 1 tilting, and through guide groove 2, collects and enters coarse grained abrasive aggregate bin 3; The abrasive grain that granularity is less than wide-meshed screen 1 mesh size falls to baffle plate B17 above through wide-meshed screen 1, then along the baffle plate B17 tilting, enters fine screen mesh 16 upper ends.The abrasive grain that granularity is less than fine screen mesh 16 mesh sizes falls to baffle plate A15 above through fine screen mesh 16, then along sloping baffle A15, falls to being collected to enter finer abrasive aggregate bin 14; The abrasive grain that granularity is greater than fine screen mesh 16 mesh sizes falls along the fine screen mesh 16 tilting, the abrasive grain homogeneous grain diameter that now process wide-meshed screen 1 and fine screen mesh 16 screen.Then abrasive grain enters flow distribution plate guide groove 4 through the shunting action of flow distribution plate guide groove 4, and abrasive grain, along being laterally uniformly distributed, falls to buffer board 5.The Main Function of buffer board 5 is the movement velocitys that reduce abrasive grain, and when the decelerating effect motion of abrasive grain process buffer board 5 falls to conveyer belt 11, speed is very little, or almost nil.Abrasive grain is evenly distributed on conveyer belt 11 surfaces, the good abrasive grain of convexity ratio falls along the conveyer belt 11 tilting, in the poor abrasive grain dropping process of circularity because drag effect falling speed is less than the good abrasive grain of circularity, broken abrasive grain directly rests on conveyer belt 11 surfaces, conveyer belt 11 moves along the direction shown in Fig. 1, the broken abrasive grain that rests on conveyer belt 11 surfaces is transported to conveyer belt 11 upper ends, fall into broken abrasive material aggregate bin 12, by regulating the rotating speed of motor 10 can change the speed of conveyer belt 11, when conveyer belt reaches certain speed, the poor abrasive grain of circularity is also transported to conveyer belt 11 lower ends and falls into broken abrasive material aggregate bin 12, the good abrasive grain of circularity falls in abrasive material aggregate bin 8 along inclination conveyer belt surface.Finally, what in coarse grained abrasive aggregate bin 3, collect is the abrasive grain that granularity is larger, and what in finer abrasive aggregate bin 14, collect is the abrasive grain that granularity is less, and the abrasive grain in these two aggregate bins can further screen; What in broken abrasive material aggregate bin 12, collect is broken and the poor abrasive grain of circularity, and these particles are undesirable, can make other purposes; What in abrasive material aggregate bin 8, collect is homogeneous grain diameter, the good abrasive grain of circularity.
The angle of inclination of wide-meshed screen 1 and fine screen mesh 16 can regulate according to different abrasive materials, guarantees that abrasive grain relies on Action of Gravity Field to fall smoothly.The order number of wide-meshed screen 1 and fine screen mesh 16 can require to change according to different abrasive grain requirements and different granularity uniformity.The angle of inclination of conveyer belt 11 and speed can require regulate according to different circularity, when abrasive material circularity requires when high, can realize by the speed that reduces the angle of inclination of conveyer belt 11 or accelerate conveyer belt 11, contrary when abrasive material circularity is less demanding.
