Abstract
The invention discloses an internal mixer, comprising two rotors which are parallel to each other in reversing rotation, wherein each rotor comprises a rotor body and six ribs arranged on the surface of the rotor; the six ribs comprise four long ribs and two short ribs, the four long ribs are symmetrically distributed at 90 degrees on the cross section of the rotor, and the two short ribs are radially distributed at 180 degrees on the cross section of the rotor; and the internal mixer further comprises a top peg and an air cylinder, in which the top peg is arranged. By changing the initial position of the top peg and the structure of the ribs of the rotors, the internal mixer disclosed by the invention has the advantages of good feeding performance and highly strong processing capability, and is capable of greatly reducing an over-refining or scorching phenomenon of the sizing materials due to shortened mixing time, greatly enhancing the mixing efficiency and effect of the internal mixer, and improving production.
Description
Technical field
The present invention relates to a kind of banbury, belong to the processing of high molecular material apparatus field.
Background technology
Banbury in the market generally comprises banburying chamber, two rotors, rotor seals, reinforced material pressing device, device for discharging, transmission device and supports, and general rotor also only contains one main one secondary two fins.There are the problems such as mixing cycle is long, melting effect is poor, melting efficiency is low in such banbury.To improve mixer mixing effect and efficient.
Summary of the invention
Technical problem to be solved by this invention provides the banbury that a kind of mixing cycle is short, melting effect good, melting efficiency is high.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of banbury, described banbury comprise that two are parallel to each other and along counter-rotational rotor, and each described rotor comprises rotor body and is positioned at six fins of rotor surface.
Further, described six fins comprise four long ribs and two short ribs, and it is symmetrical that described four long ribs are 90 degree at described rotor cross-section, and described two short ribs are radially 180 degree distributions at rotor cross-section.
Further, described fin is helical form.
Further, described banbury also comprises floating weight and cylinder, and described floating weight is positioned at described cylinder interior.
Beneficial effect: banbury provided by the invention is by the initial position of change floating weight and the structure of rotor nog, so that banbury of the present invention had both had good material feeding performance, has again extremely strong working ability, because the shortening of mixing time, the phenomenon that sizing material is crossed refining or incipient scorch also greatly reduces, therefore the melting efficiency of banbury and melting effect all strengthen greatly, and output also is improved.

The first rotor 1, the second rotor 2, rotor body 3, long rib 4, short rib 5;
Fig. 2 is the cross sectional representation of closed-smelting machine rotor provided by the invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment only is used for explanation the present invention and is not used in and limits the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
As shown in Figure 1, banbury provided by the invention comprises that two are parallel to each other and along counter-rotational rotor, these two rotors that are parallel to each other are respectively the first rotor 1 and the second rotor 2, if the first rotor 1 is turned left, then the second rotor 2 is turned right, each rotor includes rotor body 3 and is positioned at six helical rib of rotor surface, article six, helical rib comprises four along long rib 4 and two short ribs 5 along left-handed 45 degree of rotor shaft direction of rotor shaft direction dextrorotation 30 degree, rotor is cylindrical, article four, to be 90 degree at the circumferential surface of rotor cross-section symmetrical for long rib 4, and two short ribs 5 are radially 180 degree distributions at the circumferential surface of rotor cross-section.The fin of rotor surface makes sizing material move along rotor axial, and by the continuous stirring of two rotors that are parallel to each other, sizing material repeatedly produces distortion and recovers distortion, thereby reaches fast the required effect of plasticating of sizing material; In addition, when mixer mixing, sizing material all must be subject to the pressure-acting of floating weight, to reduce the non-packing space in the confined chamber, makes its filling extent improve 10%.Ram piston pressure is according to banbury material feeding situation, changes with the variation of main frame running current, generally about 0.3 ~ 0.6MPa.Traditional floating weight initial position is positioned at the bottom of cylinder, not enough in the banbury material feeding, when the main frame electric current reduces, floating weight can be pressed inward from cylinder bottom, but this moment, the initial position of floating weight was positioned at cylinder bottom, owing to be subjected to the impact in space, just can eject floating weight after needing injecting compressed air to produce pressure, floating weight reaction action relatively lags behind, affect the mixer mixing effect, the floating weight initial position is arranged on the middle part of cylinder, utilize the compressed air that is stored in the cylinder, the reaction action of floating weight is obviously accelerated, and helps the melting effect of banbury.
Adopt the floating weight initial position to be located at cylinder bottom, rotor only contains a banbury of leading secondary two fins to be organized in contrast, adopts banbury provided by the invention (embodiment 1) as experimental group, to the results are shown in Table 1.
