The base of shearing blade is connected to the upper surface of lower round platform.Shearing blade is along tangential setting in the present embodiment, i.e., without upper and lower
The middle axial direction of round platform.Rotation axis M2 is coaxially fixed on the bottom surface of lower round platform, so as to drive mounting base 22b to rotate, and then drives
Rotating vane rotation carries out the shearing of material.
The side enclosure wall 21b of holding tank C1 has some perforation side enclosure wall 21b and connects material outlet K2's and holding tank C1
Material channel T1, for allowing the material after shear-mixed to flow to material outlet K2 from holding tank C1.Material channel T1 is to open up
In the hole of the side enclosure wall 21b of holding tank C1 or bar-shaped trough.It is illustrated as bar-shaped trough.Certainly, the multiple shearings of setting for diagram are mixed
The situation of mechanism 20 is closed, the material flowed down from the material channel T1 of upper level shear-mixed mechanism 20 will enter next stage and shear
The material cutting area Q1 of mixed organization 20 carries out shear-mixed again；Then just lead to from the material of next stage shear-mixed mechanism 20
Road T1 flows out to the material outlet K2 on housing 10.
In the present embodiment, the set-up mode of rotation axis M2 for driving shearing blade is：From the bottom up axially through
Housing 10 and fixed shear part 21, and enter in holding tank C1.Shearing blade is fixed in rotation axis M2 and is located in holding tank C1
The periphery of shaft part.One end that rotation axis M2 is located at outside housing 10 is configured to rotate under the driving of driving device M1.
Driving device M1 can be directly connected to the electric rotating machine of rotation axis M2 or can drive rotation axis by drive mechanism
The rotating devices of M2.It is illustrated as directly being driven by electric rotating machine.In the present embodiment, rotation axis M2 through at housing 10 by close
Seal 13 seals, and avoids housing 10 from revealing.In the present embodiment, (do not shown by bearing between rotation axis M2 and fixed shear part 21
Go out) rotation connection.In this way, driving device M1 drives rotation axis M2 to rotate, and then rotation cutting member 22 is driven to be relatively fixed shearing
The rotation of part 21 carries out shearing manipulation.
As described above, be axially distributed two shear-mixeds along rotation axis M2 are equipped with the present embodiment, in housing 10
Mechanism 20.The rotation cutting member 22 of Liang Ge shear-mixeds mechanism 20 drives by rotation axis M2 to be rotated, and carrying out two-stage to material cuts
Cut married operation.In other embodiments, it may also be configured to the multistage shear-mixed operation of three-level and the above.Certainly, also can be only
One shear-mixed mechanism 20 is set.
Referring to Fig. 3, Fig. 4, the fixed shear part 21 in the present embodiment includes the side enclosure wall 21b of bottom plate 21a and circular ring shape.Bottom
Plate 21a and side enclosure wall 21b surrounds foregoing holding tank C1 jointly.Material channel T1 is multiple along the circumferentially spaced bars of side enclosure wall 21b
Shape groove.Radial direction perforation side enclosure wall 21b of the bar-shaped trough along side enclosure wall 21b.
There is gap T2 circumferentially referring again to Fig. 1, between fixed shear part 21 and the inner wall of housing 10, allow through cutting
Material after cutting is flowed out from gap T2.Also affixed material baffle 30 in housing 10.Material baffle 30 is located on fixed shear part 21
Side, and be blocked on the T2 of gap, so as to avoid directly flowing down and without cutting by gap T2 from the material that material inlet K1 enters
Cut mixed processing.Material baffle 30 is arranged to loop configuration, and outer edge is fixed on the inner wall of housing 10.
Fig. 6, Fig. 7 show the structure diagram of the another embodiment of the shear-mixed mechanism 20 in the present embodiment.
The shear-mixed mechanism 20 further includes gap adjustment in addition to the fixed shear part 21 and rotation cutting member 22 of foregoing relative rotation
Structure 23.Preferably, the outside of cutting member 22 and the inner side fitting of gap adjustment structure 23 or basic fitting are rotated；Wherein, turn
The outside of dynamic cutting member 22 refers to periphery, inside circumference, the base of gap adjustment structure 23 where the radial outer end of shearing blade
It is a narrow slit that this fitting, which refers between both corresponding side faces, such as width is less than or equal to the narrow slit of 3mm.Gap adjustment structure 23
Between the periphery for rotating cutting member 22 and the side enclosure wall 21b of holding tank C1, for adjusting the aperture of material channel T1.Gap
Adjustment structure 23 is arranged to be movably connected in fixed shear part 21 and can be relatively fixed cutting member 21 and circumferentially rotate, with

In summary describe, the embodiment of the present invention has the advantages that：
1st, through this embodiment in shear mixer 100 can carry out being sufficiently mixed for heterogeneity material.And at this
During the low-grade location rotating speed of motor can be selected mixed effect in the case of of less demanding, saved the energy that mixing needs
Amount；
2nd, using 300 form of heat-exchanger rig, the temperature of charge in hybrid reaction region can be controlled, is conducive to the control of reaction
The raising of system and yield.
3rd, using the additional space held 210 structure type of liquid pipe section and change storage material, the volume of material memory space can
Become, can be adjusted according to the real reaction time, improve the versatility of single reaction unit, save different experiments needs
Buy the cost of different model product.
4th, for the effect for meeting reaction condition, ensureing mixing in designing, present invention employs multistage shear-mixed mechanism
20 strengthen the effect of mixing, then only select a module to carry out for mixability reactant of less demanding, therefore this hair
It is bright not only have preferable applicability at the same time energy-saving effect due to the not strong reaction unit of other adaptability.
5th, the reaction structure form mixed by force is employed in the present invention, more conventional mixed reactor saves space.
6th, the shear mixer 100 with gap adjustment structure 23 can be according to reaction to mixing journey in the embodiment of the present invention
The requirement of degree, changes the diverse location that adjusting buckle 23a is in regulating tank C2, forms different shear-mixed effects, improves anti-
Answer the adaptability of device.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the invention, for the skill of this area
For art personnel, the invention may be variously modified and varied.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should all be included in the protection scope of the present invention.
