Abstract

The utility model relates to a seamless combined structure for superfine crushing, which comprises a flange of a bearing seat, a stator, and a rotor. The flange of the bearing seat is fixed onto a machine base; the stator is fixed onto the flange of the bearing seat; the rotor is provided with a plurality of eccentric and uniformly distributed blades and is fixed onto a rotary shaft which is connected with a motor shaft. The end portion of each blade of the rotor is provided with a groove, and the internal part of the groove is provided with a roller. The utility model has the advantages that when the rotor conducts the high-speed rotation, the high-hardness roller can roll close to the internal wall of the stator; the shearing processing of the hydraulic shearing zone is reinforced, and simultaneously, the strong shearing of the pure machine can be formed. The materials can obtain high-speed and high-fineness crushing; the material particles can reach to the micrometer level refinement, and the superfine crushing time can be shortened.

Description

A kind of ultra-fine grinding does not have the gap combining structure

The utility model relates to a kind of mixing and emulsifying and reducing mechanism that is used for industry such as food, cosmetics, chemical industry, medicine.

At present in industries such as food, cosmetics, chemical industry, medicine, mixing and emulsifying and pulverizing to liquid-liquid phase and liquid-solid phase working media, as produce products such as chocolate mass, cosmetic emulsion, paint, printing ink, pigment, coating, extensively adopt a kind of shearing mixing and emulsifying device.This device has a columnar stator and a rotor that has some paddles, described paddle is eccentric uniform on rotor, and keep certain clearance with stator inner wall, rotor is rotation at a high speed under driven by motor, working media is sucked by the opening part of high speed rotor rotated from stator, gap by stator and rotor after the shear agitation of rotor, discharge opening from the stator sidewall sprays, and enter new round circulation, working media and is pulverized and emulsification through repeatedly circulating like this under violent mechanical force and fluid power effect.But owing to have certain clearance between the stator of this device and rotor, so the bigger material of adhesion between the molecule agglomerate is difficult to by further refinement.

Order of the present utility model has the roller that is by means of in the setting of above-mentioned rotor paddle end, basically realize no gap combination between stator and rotor, thereby make working media by ultra-fine grinding, further improve the fineness of product, to satisfy high-quality requirement as some industries such as paint, pigment, coating.

A kind of ultra-fine grinding of the present utility model does not have the gap combining structure, comprise a bearing block flange, a stator, a rotor, wherein bearing block flange is fixed on the support, stator is fixed on the bearing block flange, and rotor has the uniform paddle of some off-centre, and is fixed in the rotating shaft, the bearing that this rotating shaft is passed on the bearing block flange is connected with motor shaft, each paddle end of described rotor has a groove, and the opening of this each groove is towards the inwall of stator, and is equipped with roller in each groove.

Now lift a preferred embodiment and the utility model is described in further detail in conjunction with its accompanying drawing.

Fig. 1 is the structure chart of the utility model one preferred embodiment.

Fig. 2 is that the A of Fig. 1 is to view.

The structure of the utility model one preferred embodiment such as Fig. 1 and shown in Figure 2, comprise bearing block flange 3, stator 4, rotor 5, wherein bearing block flange 3 is fixed on the support (end shows among the figure) by screw rod 1, and stator 4 is fixed on the bearing block flange 3, and rotor 5 is fixed in the rotating shaft 2, the bearing 7 on the bearing block flange 3 is passed in this rotating shaft 2, is connected with motor shaft.The paddle 5a of uniform four arranged off-centre on the described rotor 5, end at each paddle 5a of this rotor 5 has a groove 5b, the opening of this each groove 5b is towards the inwall of cylindrical stator 4, and in each groove 5b, be equipped with high rigidity roller 8, divide antetheca and rear wall 5c as this groove of rotation direction by rotor, wherein the rear surface 5c of each groove 5b slightly tilts to opening direction, therefore when rotor 5 rotates at a high speed, roller 8 is close to stator 4 inwalls and is rolled under groove rear surface 5c and action of centrifugal force, form gapless structure, simultaneously because the rotating speed of rotor 5 is high, and roller 8 is under rotor 5 high-speed driving, form higher rotating speed, material is applied strong spreading.Material enters region trochanterica by the opening part of stator 4, through rotor paddle 5a shearing pulverizing and after roller 8 high speed spreadings, the material of height refinement ejects strongly from the discharge opening 4a on stator 4 walls, and enters a new round and circulate, material in circulation repeatedly by ultra-fine grinding.

The utility model has the advantage of the roller of high rigidity when rotor high-speed rotates, Under the thrust on centrifugal force and paddle groove inclined-plane, be close to stator inner wall and roll, form Gapless structure, strengthened the shear strength of fluid power shear zone, also formed strong simultaneously Strong pure mechanical shearing makes material obtain the pulverizing of high-speed high fineness, moreover at rotor During High Rotation Speed, roller is because rolling at stator inner wall, and itself also forms the high speed rotation, Per minute forms strongly material and rolls from passing on several ten thousand ~ hundreds of thousands, makes the material height Fineness refinement, thereby the not only further refinement of particle of material reach micron-sized fineness, And shortened the time that material fining is pulverized.
