Preferably, the top in said pulverizing storehouse is provided with the main shaft holder, and the upper end of said first main shaft and said second main shaft is positioned at said main shaft holder.
After having adopted technique scheme; The beneficial effect of the utility model is: owing in pulverizing the storehouse, vertically be provided with the first parallel main shaft and second main shaft; Be provided with emery wheel respectively on two main shafts; In prior art, had better grinding effect a main shaft drive emery wheel grinding material, its milling time shortens, and has improved operating efficiency.
Because first emery wheel is identical with the quantity of second emery wheel; And first have the overlapping region between emery wheel and second emery wheel; Then first main shaft and second main shaft are when rotated; Not only can through emery wheel be arranged at the abrasive media of pulverizing in the storehouse and grind material, and first emery wheel and second emery wheel are when rotated, certain shear action also can be played to material in zone between the two; Can play the effect of assisted milling equally; So not only through increase main shaft, emery wheel quantity has increased grinding effect, and has further increased grinding effect through the shear action between emery wheel and the emery wheel, from the finished product slurry outlet, discharge after the classified rotor classification of ultra-fine material after grinding to get final product.
Owing on first main shaft and second main shaft, fixed first linkage gear and second linkage gear respectively; First linkage gear and the engagement of second linkage gear; The upper end of first main shaft connects the motor output wheel; Then drive first main shaft and rotate, can drive second main shaft through first linkage gear, second linkage gear and rotate, thereby realize pulverizing in the storehouse grinding material through the motor output wheel.
Owing to above the pulverizing storehouse, be provided with the main shaft holder; The upper end of first main shaft and second main shaft lays respectively in the main shaft holder; Then in the sand mill course of work; The main shaft holder can guarantee that first main shaft and second main axis rotation are stable, does not depart from pivot separately, guarantees the operate as normal of sand mill.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: 1. pulverizing storehouse; 11. charging aperture; 12. charging adjustment valve; 21. first main shaft; 22. first emery wheel; 31. second main shaft; 32. second emery wheel; 4. classification rotor; 5. finished product slurry outlet; 6. power set; 61. motor output wheel; 62. main shaft holder; 63. second linkage gear; 64. first linkage gear.
The specific embodiment
Shown in accompanying drawing, a kind of embodiment for the two main shaft sand mills of the utility model comprises columniform pulverizing storehouse 1, is provided with charging aperture 11 in the bottom in said pulverizing storehouse 1, and said charging aperture 11 is provided with charging adjustment valve 12 in order to the control charging rate.
The top in said pulverizing storehouse 1 is provided with classification rotor 4, is connected with finished product slurry outlet 5 on the said classification rotor 4, and when two main shaft sand mills were worked, said classification rotor 4 can carry out the material of different fineness discharging from said finished product slurry outlet 5 after the classification.The inside in said pulverizing storehouse 1 vertically is provided with the first parallel main shaft 21 and second main shaft 31; Be fixed with a plurality of first emery wheels 22 on said first main shaft 21; Be fixed with a plurality of second emery wheels 32 on said second main shaft 31; And said first emery wheel 22 is identical with the quantity of second emery wheel 32, and said first emery wheel 22 and second emery wheel 32 have certain overlapping region in vertical direction, and the vertical range between each first emery wheel 22 and another second emery wheel 32 is very small; When said first main shaft 21 and 31 rotations of second main shaft; Can not only grind material through first emery wheel 22, second emery wheel 32 and abrasive media, and can through each first emery wheel 22 and and its second emery wheel 32 of being close between the gap material played shear the effect of grinding, so just greatly improved the grinding efficiency of this sand mill.
The upper end of said first main shaft 21 and second main shaft 31 is stretched out the top in said pulverizing storehouse 1 respectively; Be provided with the power set 6 that are used to drive said first main shaft 21 and second main shaft 31 simultaneously at the top in said pulverizing storehouse 1; Said power set 6 comprise first linkage gear 64 and second linkage gear 63 of engagement; Said first linkage gear 64 is fixed on said first main shaft 21, and said second linkage gear 63 is fixed on said second main shaft 31, and the upper end of said first main shaft 21 connects motor output wheel 61; Like this; Drive 21 rotations of first main shaft through said motor output wheel 61, can be further drive 31 rotations of second main shaft, thereby said pulverizing storehouse 1 inner material is ground through first linkage gear 64, second linkage gear 63.
In addition; Can stablize when guaranteeing said first main shaft 21 and the rotation of second main shaft 31; Do not depart from its pivot; Above said pulverizing storehouse 1, also be provided with main shaft holder 62, the upper end of said first main shaft 21 and second main shaft 31 extend in the said main shaft holder 62 respectively and can pass through bearings.
The course of work of this pair main shaft sand mill is:
At first; In pulverizing storehouse 1, add an amount of abrasive media; This abrasive media and institute's grinding material are with a kind of material, and just the volume of abrasive media will more not only can grind material through the bigger abrasive media of volume; And can not produce other impurity in the process of lapping, guarantee the purity of material.
Then, starter motor makes 61 rotations of motor output wheel, simultaneously the slip (promptly in institute's grinding material, adding an amount of water) of semi-fluid condition is sent into from charging aperture 11 and is pulverized in the storehouse 1, and control charging rate through charging adjustment valve 12.
At last, slip in pulverizing storehouse 1 through the grinding of first emery wheel 22, second emery wheel 32 and abrasive media, and through after the classification of classification rotor 4 from 5 discharges of finished product slurry outlet, promptly become final products after passing through drying and packaging.
