Detailed description of the invention
Now by reference to the accompanying drawings the utility model is described in further details.
As illustrated in fig. 1 and 2, wear-resistant fluted disc of the present utility model forms primarily of the first fluted disc body 11 of circle and the second fluted disc body 12, crushing tooth 3 and the installing hole 4 that is arranged on the second fluted disc body 12 center, and crushing tooth 3 is arranged between the first fluted disc body 11 and the second fluted disc body 12 removably.In order to ensure the wearability of wear-resistant fluted disc, extend its service life, the utility model adopt have superior intensity, hardness, insulating properties, heat transfer, high temperature resistant, resistance to oxidation, corrosion-resistant, abrasion performance, elevated temperature strength structural ceramics component to prepare fluted disc body 1 and crushing tooth 3.Such as adopt common zirconia ceramics component, silicon nitride ceramics component, silicon carbide ceramics component etc.Crushing tooth 3, in fine strip shape, is preferably fine strip shape blade, thus improves crush efficiency.In order to realize feeding and discharging fast, need in certain angle of inclination between crushing tooth 3 and the first fluted disc body 11 (or second fluted disc body 12) radial direction, thus make material can flow to second crushing tooth 3 from the inclined-plane of crushing tooth 3 immediately after the fragmentation through a crushing tooth 3, both can increase crush efficiency, the generation of blocking can be reduced again.Angle between crushing tooth 3 and the first fluted disc body 11 (or second fluted disc body 12) radial direction is preferably 40 °-50 °.Wherein, the best angle of the angle between crushing tooth 3 and the first fluted disc body 11 (or second fluted disc body 12) radial direction is 45 °.
More specifically, as shown in Figures 3 and 4, the first fluted disc body 11 is provided with the first locating hole 51, first locating hole 51 is preferably countersunk head screw hole, it mainly plays installs fixing effect, and parts can be fixed by the mode of screw, thus convenient installation and inspection.First locating hole 51 is 3-5, is distributed on the ring of the first fluted disc body 11.Adopt such setting, the first fluted disc body 11 can be made well to fix while reducing locating hole quantity, increasing by the first fluted disc body 11 rigid.2-9 the first crushing tooth draw-in groove 21 is evenly equipped with between the first locating hole 51 and the first locating hole 51.First crushing tooth draw-in groove 21 is arranged on the first fluted disc body 11 right side, in elongated strip.The number of crushing tooth draw-in groove 21 is relevant with size with the number of size and crushing tooth 3, and number and arranging of size mainly consider following two aspects: one is increase crushing tooth to increase crush efficiency, and two is reduce crushing tooth to reduce the generation of blocking.Such as, in the present embodiment, the length of crushing tooth 3 is 1:3 with the ratio of the radius of the first fluted disc body 11, first locating hole 51 is 4, lays respectively at orthogonal two diameter places of the first fluted disc body 11, and the crushing tooth number now between the first locating hole 51 and the first locating hole 51 is 3.Angle between first crushing tooth draw-in groove 21 and the first fluted disc body 11 radial direction equals the angle between crushing tooth 3 and the first fluted disc body 11 radial direction, and be namely preferably 40 °-50 °, optimal selection is 45 °.Also be provided with the through hole 6 passed for material at the center of the first fluted disc body 11, through hole 6 can make material directly enter fluted disc inside from the left side of the first fluted disc body 11, thus strengthens pulverizing speed.
The shape of the second fluted disc body 12 and structure are as shown in Fig. 5, Fig. 6 and Fig. 7.As seen from the figure, the rounded boss-shaped of the second fluted disc body 12.Side is protruded and right side offers an installing hole 4, for installing driving shaft at the second fluted disc body 12.Installing hole 4 is preferably square.Square opening can make the second fluted disc body 12 more firmly be connected with driving shaft, even if also can keep good connection when grinding stressed.In the second fluted disc body 12, the left side corresponding with installing hole 4 is provided with fixing hole 7, for fixed drive axle.The second crushing tooth draw-in groove 22 and the second locating hole 52 is also provided with in the left side of the second fluted disc body 12.Second locating hole 52 is also countersunk head screw hole and corresponding with the position of the first locating hole 51, thus the first fluted disc body 11 and the second fluted disc body 12 is closely fixed together by screw.Second crushing tooth draw-in groove 22 is also in fine strip shape, its shape, size and all identical with the shape of the first crushing tooth 21, size and the angle between the first crushing tooth 21 and the first fluted disc body 11 radial direction with the angle between the second fluted disc body 12 radial direction, thus the two ends of crushing tooth 3 can be made to insert respectively in the first crushing tooth draw-in groove 21 and the second crushing tooth draw-in groove 22.Second fluted disc body 12 is provided with and the pilot hole 8 of fixing hole 7 with circumference, pilot hole 8 is for making the installation and removal of the second fluted disc body 12 more convenient.
During installation, first driving shaft is fixed in the second fluted disc body 12 by fixing hole 7, again crushing tooth 3 is inserted in the second crushing tooth draw-in groove 22, then make the left side of the second fluted disc body 12 relative with the right side of the first fluted disc body 11, the other end of crushing tooth 3 is inserted in the first crushing tooth draw-in groove 21, finally by the first locating hole 51 and the second locating hole 52, first fluted disc body 11 and the second fluted disc body 12 are fixed together.Thus, the installation of the wear-resistant fluted disc of the utility model is completed.When pulverizer works, motor orders about driving shaft and rotates, driving shaft drives the second fluted disc body 12, first fluted disc body 11 and the crushing tooth High Rotation Speed between the first fluted disc body 11 and the second fluted disc body 12, part material directly and crushing tooth collide, thus reach the object of pulverizing, another part material enters fluted disc inside by the through hole 6 of the first fluted disc body 11 central authorities, collide with one of them crushing tooth 3, and then flow to second crushing tooth 3 from first crushing tooth 3, continue collision crashing, thus reach the object of efficient pulverizing.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned embodiment and revise.Therefore, the utility model is not limited to detailed description of the invention disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this description, these terms just for convenience of description, do not form any restriction to the utility model.
