Description
Technical field
The utility model relates to a kind of suspension mill, particularly relates to a kind of grinding roller with helical groove structure for grinding the large material of compression strength.
Background technology
At present, the grinding roller of existing overhang roll mill forms huge centrifugal force in the process along bull ring inner ring circular motion, therefore huge extruding force is produced between bull ring and grinding roller, the material needing to pulverize is sent between grinding roller and bull ring by perching knife, under the effect of extruding force, material is broken, grind and become powder, is then taken away by the air-flow that blower fan blasts and collects.But, the material that existing overhang roll mill is large for some toughness, compressive resistance intensity is large, it cannot be carried out grinding by extruding force only by grinding roller and bull ring fast and effectively, these materials need just can overcome the intermolecular interaction force of material through extruding repeatedly, little by little by grinding, abrasive dust efficiency is low.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of grinding roller with helical groove structure, material can be moved upward along grinding roller helicla flute, and effectively can improve the abrasive dust efficiency of overhang roll mill.
The technical solution adopted in the utility model is: a kind of grinding roller with helical groove structure, comprise shaft of grinding roller, be arranged on the grinding roller core of shaft of grinding roller bottom, be arranged on the grinding roller on grinding roller core, be arranged on the grinding roller sleeve of shaft of grinding roller outside and be arranged on the horizontal axis tam of grinding roller sleeve side, it is characterized in that: grinding roller sleeve is positioned at above grinding roller core; Shaft of grinding roller top is provided with upper press cover, and upper press cover is connected with the upper end of grinding roller sleeve; Shaft of grinding roller upper end is provided with big nut one, under big nut one is positioned at upper press cover, in grinding roller sleeve; Shaft of grinding roller is provided with bearing one, described bearing one is positioned at below big nut one; Shaft of grinding roller is provided with bearing two, described bearing two is positioned at the lower end of grinding roller sleeve, and in grinding roller sleeve; Grinding roller core retainer plate is located at outside shaft of grinding roller, and grinding roller sleeve is located at outside grinding roller core; Shaft of grinding roller is provided with lower cover, and the upper end of lower cover is connected with the lower end of grinding roller sleeve; The bottom of grinding roller and grinding roller core is provided with pressing plate; The bottom of shaft of grinding roller is provided with big nut two, and big nut two is positioned at below pressing plate; The outer surface of grinding roller is provided with helicla flute.
The utility model has the advantage of: structure is simple, the basis of existing grinding roller is slightly done change can realize, helicla flute on grinding roller not only increases the extruding force between grinding roller and bull ring, and adds the shearing force to material, enhances the adaptability to difficult-to-grind materials; When material is between band spiral fluted grinding roller and bull ring, can not as after smooth grinding roller direct whereabouts, then needing perching knife again to throw could by grinding, but upwards thrown by the active force that helicla flute rotation produces, by the direct grinding of a rear grinding roller, decrease material repeatedly by the link that perching knife is thrown, improve the efficiency of grinding.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of grinding roller with helical groove structure, comprise shaft of grinding roller 5, be arranged on the grinding roller core 10 of shaft of grinding roller 5 bottom, be arranged on the grinding roller 9 on grinding roller core 10, be arranged on the grinding roller sleeve 4 of shaft of grinding roller 5 outside and be arranged on the horizontal axis tam 6 of grinding roller sleeve 4 side, it is characterized in that: grinding roller sleeve 4 is positioned at above grinding roller core 10, shaft of grinding roller 5 top is provided with upper press cover 1, and upper press cover 1 is connected with the upper end of grinding roller sleeve 4.Shaft of grinding roller 5 upper end is provided with big nut 1, and big nut 1 is positioned at upper press cover 1 time, in grinding roller sleeve 4.Shaft of grinding roller 5 is provided with bearing 1, bearing 1 is positioned at below big nut 1.Shaft of grinding roller 5 is provided with bearing 27, bearing 27 is positioned at the lower end of grinding roller sleeve 4, and in grinding roller sleeve 4.Grinding roller core 10 is set in outside shaft of grinding roller 5, keyway 1 is provided with as in preferred grinding roller core 10, on shaft of grinding roller 5 with keyway 1 on grinding roller core 10 relative to position be provided with key 1, keyway 1 and key 1 match, and grinding roller core 10 is enclosed within shaft of grinding roller 5 by key 1.Grinding roller 9 is set in outside grinding roller core 10, is outside equipped with key 2 16 as preferred grinding roller core 10, on grinding roller 9 with key 2 16 on grinding roller core 10 relative to position be provided with keyway 2 17, key 2 16 and keyway 2 17 match, and grinding roller core 10 is enclosed within grinding roller 9 by key 2 16.Shaft of grinding roller 5 is provided with lower cover 8, lower cover 8 is between grinding roller sleeve 4 and grinding roller core 10, and the upper end of lower cover 8 is connected with the lower end of grinding roller sleeve (4).The bottom of grinding roller 9 and grinding roller core 10 is provided with pressing plate 11.The bottom of roll shaft 5 is provided with big nut 2 12, and big nut 2 12 is positioned at below pressing plate 11.The outer surface of grinding roller 9 is evenly provided with groove, be spiral helicla flute 13 as preferred this groove, material rotates by helicla flute 13 active force produced and is upwards thrown in overhang roll mill, then by the direct grinding of a rear grinding roller, decrease material repeatedly by link that perching knife is thrown, improve the efficiency of grinding, and material not only bears extruding force between the grinding roller and bull ring of band helicla flute 13, but also bear the shearing force that helicla flute 13 acts on it, be therefore with the grinding roller of helicla flute 13 can improve the milling capacity of the material that overhang roll mill is large to toughness, compression strength is large.
