Description
Technical field
The utility model relates to milling apparatus technical field, is specially a kind of new multistage milling apparatus.
Background technology
In prior art, common grinder generally adopts emery wheel to drive abrasive media and slip uniform rotation to grind, because the volume and weight of abrasive media will be far longer than the volume and weight of the material in slip, therefore in the time that grinder is worked, abrasive media is tightly attached on the inwall that grinds storehouse under the effect of centrifugal force, be easy on one side along with slip rotates, move upward on one side, cause the media density of grinder bottom little, the media density on grinder top is large, the crushing effect of grinder is not good, be difficult to produce other product of special superfine powder and Subnano-class, and strengthen the classification difficulty of the grading rotor at grinder top.
Utility model content
The technical problem that the utility model solves is to provide a kind of new multistage milling apparatus, to solve the problem proposing in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions: a kind of new multistage milling apparatus, comprise: grind storehouse, main shaft, emery wheel, power set, temperature control equipment, vibrator, the bottom in described grinding storehouse has charging aperture, charging aperture is communicated with slurry tank, on charging aperture, be provided with control valve, grind in storehouse and be provided with main shaft, on main shaft, be fixed with some emery wheels, grind in storehouse and be also provided with some dividing plates, dividing plate one side is provided with vibrator, on dividing plate, also have partition board hole, dividing plate divides the inner space of grinding storehouse for three grinding chambers, the upper end of main shaft is through grinding the top in storehouse and being connected with power set, the top of grinding storehouse is provided with grading rotor, on grading rotor, be connected with discharging opening, grind outside, storehouse and be provided with temperature control equipment, grind in storehouse temperature sensor is installed, temperature sensor is connected and is controlled temperature control equipment by single-chip microcomputer.
Described main shaft inside is inlaid with vibrating head.
Described main shaft is provided with 3～9 emery wheels.
Compared with prior art, the beneficial effects of the utility model are: the utility model is provided with multiple dividing plates in grinding storehouse, grinding storehouse has been divided into multiple grinding chambers by these dividing plates, before grinder work, in the grinding chamber of bottommost, place in advance appropriate abrasive media, after grinder is started working, abrasive media can rise in grinding chamber above by partition board hole along with slip, and media density in grinding chamber reduces from lower to upper successively, until after slip stabilization of speed, due to the effect of centrifugal force, abrasive media in each grinding chamber can not enter in other grinding chamber under the barrier effect of dividing plate, thereby the media density that has ensured grinder bottom is greater than the media density on grinder top all the time, and slip can move upward by partition board hole is S-type in process of lapping, finally make the grinding effect of grinder be improved, can reach easily special superfine powder and other micro mist of Subnano-class, greatly reduce the classification difficulty of the grading rotor at grinder top simultaneously.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make of the present utility modelly to realize technological means, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of new multistage milling apparatus, comprise: grind storehouse 1, main shaft 2, emery wheel 6, power set 10, temperature control equipment 12, vibrator 13, the bottom in described grinding storehouse 1 has charging aperture 3, charging aperture 3 is communicated with the slurry tank that fills slip, on charging aperture 3, be provided with the control valve 4 for controlling charging rate, be also provided with feeding engine herein, grind in order to slip is delivered to from slurry tank in described grinding storehouse 1, in described grinding storehouse 1, be provided with main shaft 2, on described main shaft 2, be fixed with multiple emery wheels 6, in described grinding storehouse 1, be also provided with multiple dividing plates 5 simultaneously, these two dividing plates 5 are arranged in vertical direction, dividing plate 5 one sides are provided with vibrator 13, on dividing plate 5, also have partition board hole 51, described main shaft 2 is through described partition board hole 51, described dividing plate 5 divides the inner space of grinding storehouse 1 for three grinding chambers 9, the upper end of described main shaft 2 is passed the top in described grinding storehouse 1 and is connected with power set 10, top in described grinding storehouse 1 is also provided with grading rotor 8, on described grading rotor 8, be connected with discharging opening 7, grind 1 outside, storehouse and be provided with temperature control equipment 12, grind in storehouse 1 temperature sensor 11 is installed, temperature sensor 11 is connected and is controlled temperature control equipment 12 by single-chip microcomputer.
Described main shaft 2 inside are inlaid with vibrating head.
Described main shaft 2 is provided with 3～9 emery wheels 6.
The course of work of the present utility model is: first, at the appropriate abrasive media of the interior placement of grinding chamber 9 of bottommost, the material in described abrasive media and slip is same material, and just the volume of abrasive media is much bigger.Then, starting power set 10 rotates main shaft 2, open control valve 4, start feeding engine, slip is entered in grinding chamber 9 by charging aperture 3, under the effect of emery wheel 6, slip and abrasive media grind collision, simultaneously slip can move upward through partition board hole 51 is S-type, because the velocity of rotation of initial stage slip is not very high, the abrasive media of small part can enter in grinding chamber 9 above along with slip, until after the stabilization of speed of slip, abrasive media is tightly attached on the inwall that grinds storehouse 1 under the effect of centrifugal force, under the barrier effect of dividing plate 5, can not enter in the grinding chamber 9 on top, thereby ensure that the media density that grinds 1 bottom, storehouse is greater than the media density that grinds 1 top, storehouse all the time, the grinding effect of grinder is improved, can reach easily special superfine powder and other micro mist of Subnano-class.Finally, after the classification of the classified rotor 8 of slip, discharge from discharging opening 7, now, because the fineness of material has reached the rank of special superfine powder and Ya Na meter, so classification difficulty is low, grading effect is good, is conducive to improve yield rate.
In addition, the inwall in described grinding storehouse 1, emery wheel 6 and dividing plate 5 preferably adopt abrasion resistant polyurethane processing and fabricating, can effectively extend the service life of grinder, reduce the maintenance cost of equipment.
The utility model is simple in structure, and grinding effect is good, can produce other product of special superfine powder and Subnano-class, and classification difficulty is low, and grading effect is good, is conducive to improve yield rate.
More than show and described general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
