Abstract
The invention relates to a Raymond mill which comprises a millstone, a center shaft, a star rack, a mill hammer and annular grooves. The star rack is fixed on the center shaft. The mill hammer is mounted on the star rack, and the annular grooves are formed right below the millstone. The millstone is provided with a center hole and fixedly sleeved to the center shaft through the center hole and is composed of a plurality of sectorial leaves. Each two adjacent sectorial leaves form a cavity. The bottom surface of each sectorial leaf is provided with a sectorial bulge loop raised outwards. The bulge loops are arranged in the annular grooves, and gaps are formed around the reset annular grooves. Materials are settled into the cavities between adjacent leaves of the millstone from top to bottom, and during running of the millstone, the gaps are formed between the millstone and the annular grooves, so that though the bulge loops and the annular grooves form too narrow gaps, the materials are prevented from blocking and staying to cause cleaning of the millstone by lifting due to generation and viscosity of the materials during extruding and smashing.
Description
Technical field
The present invention relates to the raw material processing equipment technical field, be specifically related to a kind of Raymond mill.
Background technology
During the Raymond mill fertilizer material, due to Action of Gravity Field and other motive power immixtures, the material after part is pulverized can be deposited in bulge loop and gap, base ring groove junction.Through slightly long-time, this gap, place is filled, and whole Raymond mill can not start, and the maintenance of being forced to stop production need to be removed fertilizer in bulge loop and gap, base ring groove junction.Because fertilizer material itself has moisture, in the extruding crushing process, the heat produced not only makes temperature of charge raise, and make the evaporation of part moisture, and cause material to produce or increase viscosity, cause material viscosity to increase, sedimentation enters in bulge loop and gap, base ring groove junction after small space, by friction and Extrusion again, this partial material is solid being fixed in the contact gap just, not easy-clear.
In addition, the each removing in main shaft annulus tongue and gap, base ring groove junction before material, must be with the plum blossom frame of jack top Raymond mill, and the Main Function of plum blossom frame is to control the spindle swing amplitude, improve Whole Equipment stability, so often operation, the inevitable distortion of plum blossom frame and then the damage equipment of easily causing.So stop work and safeguard, on average approximately consume 1 hour at every turn, and will safeguard every day for several times, and then greatly affected operating efficiency.
Summary of the invention
The present invention, in order to overcome the deficiency of above technology, provides a kind of sedimentation material can enter smoothly the Raymond mill that ring groove can not stop up.
The present invention overcomes the technical scheme that its technical problem adopts:
This Raymond mill, comprise that mill, central shaft are fixed in plum blossom frame on central shaft, are installed on the mill hammer on the plum blossom frame and are arranged at the ring groove under mill, described mill center is provided with centre bore, described mill is set with and is fixed on central shaft by centre bore, described mill is comprised of some fan lobes that are sector structure, form a cavity between every two adjacent fan lobes, what be provided with outwardly convex on the bottom surface of described each fan lobe is the annular bulge loop of fan, and described bulge loop is positioned at ring groove and itself and ring groove surrounding and is provided with gap.
Above-mentioned fan lobe is three and it is uniform at circumferencial direction, and fan angle of each fan lobe is 60 °.
The invention has the beneficial effects as follows: material is deposited in the cavity between the adjacent fan lobe of mill from top to bottom; therefore in the mill running; mill and ring groove have space; make material can not cause because the space between bulge loop and ring groove is too small producing due to material in the extruding crushing process or increase viscosity to cause stopping up the resident mill rise need to the cleaning, therefore protect the plum blossom frame to extend its service life.And, owing to there being cavity, therefore under the effect of blower fan, the sedimentation logistics can enter into ring groove smoothly, has improved production efficiency.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Structural representation is looked up at Fig. 2 mill position;
In figure, 1. mill 2. ring groove 3. central shaft 4. mill hammer 5. centre bores 6. are fanned lobe 7. bulge loop 8. cavity 9. plum blossom framves.
The specific embodiment
Below in conjunction with accompanying drawing 1, the present invention will be further described for accompanying drawing 2.
This Raymond mill, comprise that mill 1, central shaft 3 are fixed in plum blossom frame 9 on central shaft 3, are installed on the mill hammer 4 on plum blossom frame 9 and are arranged at the ring groove 2 under mill 1, mill 1 center is provided with centre bore 5, mill 1 is fixed on central shaft 3 by centre bore 5 suits, mill 1 is comprised of some fan lobes 6 that are sector structure, form a cavity 8 between every two adjacent fan lobes 6, what be provided with outwardly convex on the bottom surface of each fan lobe 6 is the annular bulge loop 7 of fan, and bulge loop 7 is positioned at ring groove 2 and itself and ring groove 2 surroundings and is provided with gap.Material is deposited in the cavity 8 between the adjacent fan lobe 6 of mill 1 from top to bottom; therefore in the mill running; mill 1 has space with ring groove 2; make material can not cause because the space between bulge loop 7 and ring groove 2 is too small producing due to material in the extruding crushing process or increase viscosity to cause stopping up resident mill 1 rise need to the cleaning, therefore protect plum blossom frame 9 to extend its service life.And, owing to there being cavity 8, therefore under the effect of blower fan, the sedimentation logistics can enter into ring groove 2 smoothly, has improved production efficiency.
Above-mentioned fan lobe 6 is three and it is uniform at circumferencial direction, and fan angle of each fan lobe 6 is 60 °.Because uniform each fan lobe 6 shapes of each fan lobe 6 are consistent, and the fan angle is 60 ° and makes it approach isosceles triangle shape, so the mill all directions are stressed has evenly guaranteed the stability in its operation process, extended the service life of equipment.
