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 raw material processing equipment technical field, be specifically related to a kind of Raymond mill.
Background technology
During Raymond mill fertilizer material, due to Action of Gravity Field and other motive power immixtures, the material after part pulverizing 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, maintenance of being forced to stop production, and needs fertilizer in bulge loop and gap, base ring groove junction to remove.Because fertilizer material itself has moisture, in extruding crushing process, the heat produced not only makes temperature of charge raise, and portion of water is evaporated, cause material to produce or increase viscosity, causing material viscosity to increase, sedimentation to enter in bulge loop and gap, base ring groove junction after small space, by friction and Extrusion again, this partial material is just solid to be fixed in contact gap, not easy-clear.
In addition, in each removing main shaft annulus tongue and gap, base ring groove junction before material, must with the plum blossom frame of jack top Raymond mill, and the Main Function of plum blossom frame controls spindle swing amplitude, improve Whole Equipment stability, so often operation, the inevitable plum blossom frame that easily causes is out of shape and then damage equipment.Shut-down like this is safeguarded, average each about consumption 1 hour, and will safeguard every day for several times, and then greatly have impact on operating efficiency.
Summary of the invention
The present invention, in order to overcome the deficiency of above technology, provides a kind of sedimentation material and can enter the Raymond mill that ring groove can not block smoothly.
The present invention overcomes the technical scheme that its technical problem adopts:
This Raymond mill, comprise mill, central shaft, the plum blossom frame be fixed on central shaft, be installed on mill hammer on plum blossom frame and the ring groove that is arranged at immediately below mill, described mill center is provided with centre bore, described mill is fixed on central shaft by centre bore suit, described mill is made up of some fan lobes in sector structure, a cavity is formed between every two adjacent fan lobes, the bottom surface of described each fan lobe is provided with the bulge loop in fan annular of outwardly convex, described bulge loop is positioned at ring groove and itself and ring groove surrounding are provided with gap.
Above-mentioned fan lobe is three and it is uniform at circumferencial direction, and the fan angle of each fan lobe is 60 °.
The invention has the beneficial effects as follows: in the cavity between the adjacent fan lobe that material is deposited to mill from top to bottom; therefore in mill running; mill and ring groove have space; material can not too smallly because of the space between bulge loop and ring groove be caused in extruding crushing process because material produces or increase viscosity causes blocking resident needs by mill rise cleaning, therefore to protect plum blossom frame and extend its service life.And owing to there is cavity, therefore under the effect of blower fan, sedimentation logistics can enter into ring groove smoothly, improves production efficiency.
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. grinds hammer 5. centre bore 6. and fans lobe 7. bulge loop 8. cavity 9. plum blossom frame.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, the present invention will be further described for accompanying drawing 2.
This Raymond mill, comprise mill 1, central shaft 3, the plum blossom frame 9 be fixed on central shaft 3, be installed on mill hammer 4 on plum blossom frame 9 and the ring groove 2 that is arranged at immediately below mill 1, mill 1 center is provided with centre bore 5, mill 1 is fixed on central shaft 3 by centre bore 5 suit, mill 1 is made up of some fan lobes 6 in sector structure, a cavity 8 is formed between every two adjacent fan lobes 6, the bottom surface of each fan lobe 6 is provided with the bulge loop 7 in fan annular of outwardly convex, bulge loop 7 is positioned at ring groove 2 and itself and ring groove 2 surrounding are provided with gap.In cavity 8 between the adjacent fan lobe 6 that material is deposited to mill 1 from top to bottom; therefore in mill running; mill 1 and ring groove 2 have space; make that material can not too small causing causes blocking resident needs because material produces or increase viscosity mill 1 is risen cleaning extruding in crushing process because of the space between bulge loop 7 and ring groove 2, therefore protect plum blossom frame 9 and extend its service life.And owing to there is cavity 8, therefore under the effect of blower fan, sedimentation logistics can enter into ring groove 2 smoothly, improves production efficiency.
Above-mentioned fan lobe 6 is three and it is uniform at circumferencial direction, and the fan angle of each fan lobe 6 is 60 °.Because each fan lobe 6 each fan lobe 6 form trait uniform is consistent, and fan angle is 60 ° makes it close to isosceles triangle shape, and therefore mill all directions uniform force, ensure that the stability in its operation process, extends the service life of equipment.
