The grinder is simple in structure, good in grinding effect, capable of producing ultrafine powder sub-nanometer-grade products, low in grading difficulty and good in grading effect and facilitates improvement of rate of finished products.

Description

A kind of grinder

Technical field

The utility model relates to the grinder technical field.

Background technology

Common grinder generally adopts emery wheel drive abrasive media and slip uniform rotation to grind in the prior art, because the volume and weight of abrasive media will be far longer than the volume and weight of the material in the slip, therefore when grinder is worked; Abrasive media tightly is attached under action of centrifugal force on the inwall that grinds the storehouse; Be easy to one side along with slip rotates,, cause the media density of grinder bottom little Yi Bian move upward; The media density on grinder top is big; The crushing effect of grinder is not good, is difficult to produce other product of special superfine powder and Subnano-class, and has strengthened the classification difficulty of the classification rotor at grinder top.

The utility model content

The utility model technical problem to be solved is: a kind of grinder is provided, and this grinder has grinding effect preferably.

For solving the problems of the technologies described above, the technical scheme of the utility model is: a kind of grinder comprises and grinds the storehouse; The bottom in said grinding storehouse is provided with charging aperture; Be provided with the main shaft that is driven by power set in the said grinding storehouse, be fixed with a plurality of emery wheels on the said main shaft, the top in said grinding storehouse is provided with the classification rotor; Said classification rotor is provided with discharging opening; Said grinding is fixed with a plurality of dividing plates in the storehouse, and said dividing plate is provided with the dividing plate hole that supplies said main shaft to pass, and said dividing plate is divided into a plurality of grinding chambers with said grinding storehouse.

After having adopted technique scheme; The beneficial effect of the utility model is: owing in grinding the storehouse, be provided with a plurality of dividing plates, these dividing plates will grind the storehouse and be divided into a plurality of grinding chambers, then before grinder work; In the grinding chamber of bottommost, place an amount of abrasive media in advance; After grinder was started working, abrasive media can rise in the top grinding chamber through the dividing plate hole along with slip, and the media density in the grinding chamber reduces from lower to upper successively; After the slip stabilization of speed; Because action of centrifugal force, the abrasive media in each grinding chamber can not enter in the other grinding chamber under the barrier effect of dividing plate, thereby the media density that has guaranteed the grinder bottom is all the time greater than the media density on grinder top; And slip can move upward through the dividing plate hole is S-type in process of lapping; The grinding effect of grinder is improved, can reaches special superfine powder and other micro mist of Subnano-class at an easy rate, reduced the classification difficulty of the classification rotor at grinder top simultaneously greatly.

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. grinding storehouse; 2. main shaft; 3. charging aperture; 4. control valve; 5. dividing plate; 51. dividing plate hole; 6. emery wheel; 7. discharging opening; 8. classification rotor; 9. grinding chamber; 10. power set.

The specific embodiment

Shown in accompanying drawing, be a kind of embodiment of the utility model, comprise columniform grinding storehouse 1; The bottom in said grinding storehouse 1 has charging aperture 3, and said charging aperture 3 is communicated with the slurry tank that fills slip, on said charging aperture 3, is provided with the control valve 4 that is used to control charging rate; Also be provided with a feeding engine here; In order to being delivered to from slurry tank in the said grinding storehouse 1, grinds slip, certainly, and among the figure and not shown said feeding engine and slurry tank.

Be provided with main shaft 2 in the said grinding storehouse 1; On said main shaft 2, be fixed with a plurality of emery wheels 6 (shown in the figure is six); Simultaneously in said grinding storehouse 1, also be provided with a plurality of dividing plates 5 (shown in the figure is two), these two dividing plates 5 are arranged in vertical direction, on dividing plate 5, also have dividing plate hole 51; Said main shaft 2 passes said dividing plate hole 51, and said dividing plate 5 will grind the inner space in storehouse 1 and divide for three grinding chambers 9.The upper end of said main shaft 2 is passed the top in said grinding storehouse 1 and is connected with power set 10, also is provided with classification rotor 8 at the top in said grinding storehouse 1, is connected with discharging opening 7 on the said classification rotor 8.

The course of work of this grinder is:

At first, in the grinding chamber 9 of bottommost, place an amount of abrasive media, the material in said abrasive media and the slip is with a kind of material, and just the volume of abrasive media is much bigger.

Then, start power set 10 and make main shaft 2 rotations, open control valve 4; Start feeding engine, make slip pass through charging aperture 3 and get in the grinding chamber 9, under the effect of emery wheel 6; Slip and abrasive media grind collision, simultaneously slip can be through the dividing plate hole 51 S-type moving upward because the velocity of rotation of initial stage slip is not very high; The abrasive media of few part can enter in the top grinding chamber 9 along with slip, and after the stabilization of speed of slip, abrasive media tightly is attached under action of centrifugal force on the inwall that grinds storehouse 1; Under the barrier effect of dividing plate 5, can not enter in the grinding chamber 9 on top; Thereby the media density that has guaranteed to grind 1 bottom, storehouse is improved the grinding effect of grinder all the time greater than the media density that grinds 1 top, storehouse, can reach special superfine powder and other micro mist of Subnano-class at an easy rate.

At last, discharge from discharging opening 7 after the classification of the classified rotor 8 of slip, at this moment, because the fineness of material has reached the rank of special superfine powder and Ya Nami, so the classification difficulty is low, grading effect is good, helps improving yield rate.

In addition, the inwall in said grinding storehouse 1, emery wheel 6 and dividing plate 5 preferably adopt the abrasion resistant polyurethane processing and fabricatings, can prolong the service life of grinder effectively, reduce the maintenance cost of equipment.

This grinding machine structure is simple, and grinding effect is good, can produce other product of special superfine powder and Subnano-class, and the classification difficulty is low, and grading effect is good, helps improving yield rate.

The utility model is not limited to the above-mentioned specific embodiment, and all are based on the technical conceive of the utility model, and the structural improvement of having done all falls among the protection domain of the utility model.
