Description
Technical field:
The utility model belongs to rubber manufacturing machinery manufacture field, particularly a kind of closed-smelting machine rotor with three-dimensional micro-rib structure.
Background technology:
Banbury is the very important mixing facilities of rubber industry.Rotor is the core component of banbury, the quality of its structure and the profile design whether reasonable energy consumption, production capacity and the refining glue that directly affect banbury.Can say that the development history of banbury is also the development history of a closed-smelting machine rotor.Popular the earliest from world development, so far still world rubber industry occupies Farrel company of the U.S. F series Ben Baili banbury of critical role, to the K series banbury of the GK series banbury of German Werner & Pfleiderer company, Francis Shaw company of Britain, people have paid huge effort for closed-smelting machine rotor.
Closed-smelting machine rotor can be divided into shearing rotor and meshing rotor two kinds of citation forms, for many years, shearing-type banbury always in occupation of main market, its high shear characteristic make it rubber industry particularly tyre industry be widely used, people are referred to as output type banbury.Four rib shear rotor for internal mixer are got up to meet High-efficient Production ability development on the basis of two rib shear rotor for internal mixer, the GK-N type closed-smelting machine rotor that W & P company of Germany develops is widely applied in the rubber industry of China, becomes the main representative of shear rotor for internal mixer.
Traditional closed-smelting machine rotor is made up of the short scroll of long spire rib, and the helical angle of long spire rib is generally about 30 degree, and the helical angle of short scroll is generally about 45 degree.Sizing material is when banburying chamber's kneading, mobility status is comparatively complicated, current stabilization district and turbulent region can be produced, the low-shearing force relying on rotor turns to produce in turbulent region can complete simple kneading work, namely granular solids and liquid additive are mixed in rubber and form coherent mass under the effect of external force, and in current stabilization district, high-rate of shear and shearing force crush coherent mass and dispersion further.The gap that rotor lug, nib top and banburying chamber's inwall are formed is the current stabilization district producing shearing force, and other parts in banburying chamber are the turbulent regions producing mild method.In order to improve the number that the traditional method of mixing effect is generally the increase long rib of rotor and short rib, so both add the kneading number of times of sizing material between lug, nib top and banburying chamber's inwall, too increase the cycle-index that sizing material passes through along rotor axial simultaneously, thus reach the turbulent form exacerbating sizing material, but when the number increasing long rib and short rib can make rubber compounding, temperature sharply raises, and easily causes incipient scorch.
Summary of the invention:
The object of the invention is to the deficiency overcoming existing closed-smelting machine rotor, seek to design the melting effect that a kind of closed-smelting machine rotor effectively can improve sizing material.The present invention is on the basis of traditional tetragonous rotor, adds the micro-rib structure of some three-dimensionals, as shown in Figure 3 between short rib, long rib.Rotor placed altogether three to the micro-rib of three-dimensional, this three is the both sides being symmetrically distributed in rotor to the micro-rib of three-dimensional, three micro-ribs of three-dimensional of every side are as contrary with the hand of spiral of short rib 11 in first three-dimensional micro-rib 8 in Fig. 3, the 3rd three-dimensional micro-rib 10 hand of spiral, and second three-dimensional micro-rib 9 hand of spiral is identical with the hand of spiral of long rib 12.
When the rotor is turning, because the effect of the short rib of rotor makes sizing material flow along rotor axial, and place two hands of spiral three-dimensional micro-rib contrary with the rotor short rib hand of spiral and make sizing material produce an axial flow contrary with short rib effect, the identical identical flow direction of sizing material as shown in Figure 5 making sizing material axial flow direction and long rib place of second three-dimensional micro-rib 9 hand of spiral and long rib 12, this just make the turbulent flow aggravation of sizing material in low-shearing force district and three micro-ribs be staggered closer to long rib rib top this make the more how easier gap kneading entered between rotor lug, nib and banburying chamber's inwall of sizing material, the flow direction of the different sizing material of the suffered axial force simultaneously between sizing material levels also different this just creates a shearing force and makes sizing material again obtain kneading between levels sizing material, so the present invention is under the prerequisite not increasing the long rib of rotor and short rib number, the shearing shunting action of rotor is enhanced by the micro-rib structure of three-dimensional, thus improve mixing effect.
The micro-rib structure of the three-dimensional designed in the present invention its often pair three-dimensional micro-rib fin maximum rotating diameter is less than the maximum rotating diameter of the long rib of closed-smelting machine rotor and short rib, which prevent front and back rotor to interfere when rotating, and be also less than the axial force that short rib produces due to the little axial force that it produces of the micro-rib of three-dimensional, this guarantees sizing material still along short rib produce axial force direction move the general effect reaching and move in circles, the design of three-dimensional micro-rib structure also helps the material feeding speed that improves rotor thus improves production capacity in addition.

Detailed description of the invention:
Contrast accompanying drawing the present invention will be further described in conjunction with specific implementation method below.
Provided by the present invention is banburying chamber's part of banbury, and this part is become by rotor set before banburying chamber, 5-bearing, the upper banburying chamber of 6-, 7-under rotor, 2-bearing spider, 3-end cap, 4-after 1-as shown in Figure 2.Upper and lower banburying chamber is connected by bolt, then loads onto bearing at banburying chamber two ends, then front and back rotor is installed to banburying chamber's middle cover upper end cover, then loads onto bearing spider respectively at the two ends of armature spindle.The process of rubber processing is: open motor, and front and back rotor turns round in opposite directions in banburying chamber, and at this moment open gallery ports and drop into the closedown such as sizing material and compounding ingredient gallery ports, floating weight presses down rotor and starts material feeding.
Sizing material banburying chamber flow regime as shown in Figure 5, the responsive to axial force sizing material that sizing material is subject to short rib in the drawings flows along the direction of arrow in figure, and owing to there being two three-dimensional micro-rib hands of spiral contrary with the hand of spiral of short rib so these two micro-ribs are contrary with short rib to the axial force of sizing material, and the three-dimensional of centre micro-rib hand of spiral is also identical with the identical axial force to sizing material of short rib, just exacerbates turbulent flow like this thus reach better melting effect.And due to axial force direction contrary of micro-rib and short rib, make between sizing material levels, to there is certain shear action and so just make the further kneading of sizing material.
The maximum rotating diameter that three-dimensional micro-rib fin maximum rotating diameter is less than the short rib of rotor and long rib prevents rotor from interfering when turning round, and three-dimensional micro-rib tactical diameter tactical diameter of being less than the short rib of the long rib of rotor can make sizing material between three-dimensional micro-rib rib top and banburying locular wall, easier flowing can reduce the obstruction that three-dimensional micro-rib flows to sizing material.
The present invention is directed to the deficiency of existing closed-smelting machine rotor, devise a kind of rotor with three-dimensional micro-rib structure, this rotor effectively can strengthen the melting effect of sizing material, and under the prerequisite not changing banbury agent structure, carbon black dispension degree can improve 20%.
