Description

The high shear dispersion machine

Technical field

The utility model relates to reducing mechanism, especially a kind of high shear dispersion machine.Be applicable to shearing, grinding, the homogenizing of modifier and matrix pitch compound in the modified pitch, be particularly useful for shearing, grinding, the homogenizing of SBS modifier and matrix pitch compound in thermoplastic elastomer (TPE) (SBS) modified pitch.

Background technology

The ratio of building Modified Bitumen Pavement is more and more higher, and thermoplastic elastomer (TPE) (SBS, that is: styrene-butadiene, styrene block copolymer) modified pitch is widely used with its excellent comprehensive performances, but the SBS modified pitch will obtain good modified effect, SBS must be dispersed in the matrix pitch with extremely small particle (micron order) uniformly, yet SBS is a kind of thermoplastic elastomer (TPE) of macromolecular material, the elastic property that had both had rubber, the thermoplastic properties that has resin again, the molecular weight height, cohesive force is big, good toughness is with simple extruding, mode such as knock is difficult to the pulverizing that reaches desirable, dispersion effect.In the prior art, the general work of adopting the modified pitch grinding machine to finish pulverizing, the modified pitch grinding machine general main by: by the mill body of feed pipe and discharging opening, place in the mill body and the corresponding matching flour milling is the movable grinding disc of taper seat and static cutting disk, the position that is provided with respectively on static cutting disk and movable grinding disc is corresponding mutually cutter tooth etc. is formed, this grinding machine has solved problems such as the pulverizing, grinding of SBS modifier to a certain extent, flow is little, energy consumption is bigger but it grinds, difficulty of processing is big, is not easy to maintenance.

Summary of the invention

The technical problems to be solved in the utility model is: provide a kind of rational in infrastructure, can make SBS modifier and matrix pitch compound through repeatedly stirring, shear the high shear dispersion machine that obtains desirable fineness, even dispersion effect, solve technical problems such as the existing in prior technology flow is little, energy consumption is big, difficulty of processing is big.

The technical scheme that the utility model adopted is: the high shear dispersion machine, have fixing bearing block and the charging body that plays the bearing block effect, bearing all is housed within both, rotating shaft is housed in the bearing, what fixedly connected with bearing block is the discharging body, be fixed with connector between charging body and the discharging body, it is characterized in that intrinsic quiet shearing disk in the groove at connector two ends, what match with quiet shearing disk is the moving shearing disk that is enclosed within the rotating shaft and can rotates thereupon, all have open-work on the end face of described quiet shearing disk and moving shearing disk, being enclosed within also can be with the back-up ring that also has one a group of helical blade and an interval action of its rotation synchronously in the rotating shaft.

In the outside that described charging axon is held spacer ring, sealing ring and sealing gland are housed successively also, in the rotating shaft of the same side shaft coupling are housed.

Described helical blade is provided with 3, lays respectively in the cavity of charging body, discharging body and connector, between helical blade and moving shearing disk back-up ring is housed.

The outer ring of described charging body, discharging body and connector all is provided with the conduction oil groove of heating.

The outside of described connector is provided with leg.

The open-work of opening on described quiet shearing disk and moving shearing disk is to be the radial strip hole in center with the rotating shaft.

The open-work of opening on described quiet shearing disk and moving shearing disk is equally distributed circular hole.

The beneficial effects of the utility model are: this high shear dispersion machine has been broken the means of conventional grinding, the method of using high speed shear instead reaches the effect of fineness of grind, owing to be shear action, the active force that is sheared is on the cutting edge of two shearing disks, be the face contact on line contact rather than the conventional grinder, therefore, stressed application point is little, has reduced the consumption of power greatly, machine part processing, particularly the processing of crucial shearing disk is very simple, processing request also reduces greatly, has not only reduced the cost of complete machine, but simplified structure more, processing and maintenance are used also convenient easily.

The specific embodiment

As shown in Figure 1, present embodiment has fixing bearing block 1 and plays the charging body 7 of bearing block effect, and both are positioned at two of dispersion machine, and a bearing 2 respectively is housed in bearing block and the charging body, and rotating shaft 14 is installed on the two bearings.What fixedly connected with bearing block 1 is discharging body 3, be fixed with connector 4 between charging body 7 and the discharging body 3, above-mentioned three connects into fixing integral body with bolt, is equivalent to the housing of dispersion machine, have charging aperture above charging body 7, the below of discharging body has discharging opening.This example is the intrinsic quiet shearing disk 5 of difference in the groove at connector 4 two ends, what match with quiet shearing disk is at the one side and moving shearing disk 6 that be enclosed within the rotating shaft 14 and can rotate thereupon, all having with the rotating shaft on the end face of described quiet shearing disk 5 and moving shearing disk 6 is the radial rectangular open-work in center, being enclosed within also can be with the back-up ring 11 that also have 3 helical blades 10 and 2 interval actions of its rotation synchronously in the rotating shaft, 3 helical blades 10 lay respectively at charging body 7, in the cavity of discharging body 3 and connector 4, the back-up ring 11 of interval action has been housed between each moving shearing disk 6 and helical blade 10.The outside at the bearing 2 of described charging body 7 also is equipped with spacer ring 16, sealing ring 8 and sealing gland 17 successively, in the rotating shaft 14 of the same side shaft coupling 18 is housed, and is used for being complementary fastening with motor coupler.The outside of described connector 4 can be provided with leg 12.

This example all is provided with the conduction oil groove 15 of heating in the outer ring of charging body 7, discharging body 3 and connector 4, make the complete machine work that can be incubated or heat.

The open-work that the utility model is opened on described quiet shearing disk 5 and moving shearing disk 6 can also be equally distributed circular hole, or the open-work of other shape, as long as can shear with the cutting edge in hole.

Operation principle of the present utility model is: when motor rotates, driving rotating shaft 14 by shaft coupling 18 rotates, be contained in the helical blade 10 in the rotating shaft, back-up ring 11 and moving shearing disk 6 also rotate thereupon, because moving shearing disk 6 and quiet shearing disk 5 all have the open-work of certain strip, compound enters the back from charging body 7 and is promoted by helical blade 10, then enter the rectangular open-work of moving shearing disk 6, again because quiet shearing disk 5 is fixed, and moving shearing disk 6 is rotations at a high speed, therefore, when the rectangular open-work of the driven shearing disk of compound flows to the rectangular open-work of quiet shearing disk, because the flow velocity of compound is slow, so compound will bear tens thousand of times shearing in flowing, and through after the two-stage shearing, the fineness of compound reaches desirable requirement fully, last in the space of discharging body 3, under the effect of helical blade 10, release fast shearing good compound on the one hand, on the other hand the material of respectively filling a prescription in the compound is evenly disperseed.
