Abstract
The utility model relates to a novel rotor of a Banbury mixer, and namely a synchronous rotor which is composed of long ribs (2, 4), short ribs (3, 5), end plates (1, 6) and a long shaft (7). Two groups of ribs are arranged on the rotor. Each group of ribs is composed of a long rib and a short rib. The two groups of ribs are respectively arranged at both sides of the rotor and spirally extend towards the center position of the rotor from the end head of the rotor. Initial sides of the two groups of long ribs and short ribs are respectively connected with the end head of the rotor. But the tail end of one group of long rib and the tail end of the other group of short rib are respectively provided with a definite gap. An inner cavity and rib positions of the rotor are respectively provided with a forced circulation cooling water channel (8). When two rotors work, the two rotors move with the same speed in opposite directions, and keep a definite phase all the time. Therefore, when the rotor works, material can be quickly absorbed, sizing material can be thoroughly mixed and fined, flowability is good, batch temperature is homogeneous and cooling effect is obvious. The quality of compound and the efficiency of compound fined can be improved. The utility model is an ideal rotor of a Banbury mixer in rubber industry.
Description
The present utility model belongs to rubber manufacturing machinery, especially four prismatic rotors in the banbury.
The employed four prismatic rotors of existing closed-smelting machine rotor, its lug, nib adopts two helically shaped long ribs of dextrorotation of the two ends of working rotor part (in a side, differ 180 the degree) and two left-handed short ribs (in a side, differ 180 degree) extend and form to the centre, length rib phase difference 90 degree.During two working rotors, the length rib intersection of sizing material has the dead angle when mixing, and is mobile poor.Rotor speed has 1: 1.5: 1.16 speed difference.The rotor of this form is when work, because mobile bad, melting effect is undesirable, has influenced mix quality and refining glue efficient.Simultaneously, this rotor profile complexity, integral casting process difficulty height, its inner chamber can not be processed, and the sand removal of rotor rib is difficult for clear clean.Owing to can only adopt the cooling of the spray type of cooling, cause the rotor cooling condition poor, the cooling of rib top is bad, has influenced the thermodynamic behaviour of sizing material.
The purpose of this utility model provides a kind of novel banbury synchronous rotor, and its profile is simple, has good flowability, helps improving melting effect.
The structure of the banbury synchronous rotor that the utility model provides is described below: be made up of the long rib of rotor (2,4), short rib (3,5), end plate (1,6) and major axis (7).Have two groups of ribs on the rotor, each group is made up of a long rib and a short rib, two groups of ribs are distributed in the rotor both sides respectively, and from the termination of rotor to the rotor center position with spiral extension, wherein one group left-handed, another organizes dextrorotation, lead angle is the 55-60 degree, two group leader's ribs play initial line with short rib and all link to each other with the rotor termination, but group leader's rib terminal and the short rib terminal of another group have certain interval, and there is forced circulation cooling water channel (8) at rotor internal cavity and rib position.Two rotors are done the motion of identical speed together when work, and remain a phase bit, can be vertical (90 degree), also can be parallel (0 degree), see Fig. 5.When the direction of front and back rotor is vertical, sizable gap appears between rotor and the rotor, and make sizing material directly enter banburying chamber from charge door, can shorten the time of drawing in, so the mixing degree of sizing material is even in gamut; When the direction of front and back rotor rib is in a horizontal position, make the forceful action of sizing material direction drawing crack to the left and right between rotor and the rotor, the performance dispersion effect.One group leader's rib terminal of this closed-smelting machine rotor and the short rib terminal of another group have certain interval, and its gap remains on the distance of 0.05-0.06L.This closed-smelting machine rotor rotor internal cavity and rib portion cooling water channel are a kind of forced circulation cooling water channel.
Adopt synchronous rotor of the present utility model, can obtain following good effect.This rotor length rib is parallel, and in the same side, phase difference 135 degree makes that runner is unimpeded, rubber mobility good (seeing Fig. 1,2), can improve the quality and the efficient of elastomeric compound when mixing work.Simultaneously, the front and back spinner velocity is identical, has changed the asynchronous traditional concept that asynchronous rotor in the past has speed difference, therefore refines glue efficient height, and the temperature of a part sizing material is uniform during banburying.When installing and using two rotors, two rotors are done the motion of identical speed together when work, and remain a phase bit, can be vertical (90 degree), also can be parallel (0 degree), see Fig. 5.When the direction of front and back rotor is vertical, sizable gap appears between rotor and the rotor, and make sizing material directly enter banburying chamber from charge door, can shorten the time of drawing in, so the mixing degree of sizing material is even in gamut; When the direction of front and back rotor rib is in a horizontal position, make the forceful action of sizing material direction drawing crack to the left and right between rotor and the rotor, the performance dispersion effect.Because every roots rotor rib one end is left-handed, the other end is that dextrorotation is arranged, and tears, pushes so each root awl and banburying chamber's inwall also produce, and promote the sizing material move left and right.Therefore we can say that each roots rotor and banburying chamber can become a banbury separately.Because the phase place of rotor is same often, so the initial stage peak of power becomes samely between each batch processing, can reduce the qualitative difference of every batch of processing.For guaranteeing the fixed position of length rib, require the rib hot investment casting to make, and the machining requirement is also strict, to guarantee the shape and the phase place of rotor.Armature spindle is a forged steel pieces, and rib is through hot investment casting and armature spindle welding, rotor strength height.This closed-smelting machine rotor rotor internal cavity and rib portion cooling water channel are a kind of forced circulation cooling water channel, and waterway is close to rotor rib working face, can reach the forced circulation water quench, and heat is conducted, and is more remarkable than traditional spray cooling effect.
