Background technology
In the rubber industry, kneading is an important process procedure, also promptly makes rubber generation depolymerization degradation reaction under effects such as machinery, heat, oxygen, destroys the space network of rubber molecule, and its plasticity is necessarily recovered.Its rotor is the vitals that rubber is sheared, rotor rotation work done to raw material shear, extruding, frictional heat, its structural design directly affects the quality of service behaviour, production efficiency and the kneading sizing material of banbury.Conventional rotors mostly is a plurality of sheet rib bodies is set on the rotor pilum, the rib body is all along rotor pilum spiral extension, two rotors rotate in opposite directions in the course of work, the rib body of rotor be meshing with each other and the rib body between have a fixed gap, raw material is positioned at rib body and banburying chamber's inwall, along with rotor rotation is subjected to promoting, extruding, friction, and between two rib bodies, axially move in the gap of spiral extension.Because existing rotor rib body is thinner along its circumferential width, and the rib body that is the semiellipse shape, seamed edge with the rib body is sheared raw material, the rib body of this structure is easy to cause the wearing and tearing of seamed edge, influence service life and performance, and less than 1/3 of rotor pilum diameter, the top faceted pebble of rib body is limited to the squeezing action of sizing material, rubbing action is very little along its circumferential width for the rib body.And traditional closed-smelting machine rotor frictional heat work area is little, is mainly the friction of sizing material and banburying chamber's inwall, influences material and is rapidly heated.
The utility model content
It is big that the technical problem that the utility model solved provides a kind of fricting working surface to sizing material, shearing, the effective rubber and plastic banbury meshing rotor of kneading.
The technical solution adopted in the utility model is, rubber and plastic banbury meshing rotor, comprise a pair of rotor, the rotor pilum outer surface of each rotor is provided with the rib body, and described rib body is 41%～50% of a rotor pilum diameter along the width on the rotor pilum outer surface circumference.
Described rib body is at least two sections, and the rib body of one of them rotor engages between the rib of another rotor, and the top faceted pebble of rib body and the outer surface of another rotor pilum have the gap, have the gap between the incline face of two rib bodies that are meshed.
Described rib body is three sections, comprises a long rib body and two short rib bodies 8 that are interspersed with long rib body.
Described long rib body equals 3/4～3/5 of working rotor span access location length along the axial length of rotor pilum, is 45%～50% of rotor pilum diameter along the circumferential width of rotor pilum, and the subbase outer surface of column helical form that rotates is arranged; Described two short rib bodies are 1/3～1/2 of working rotor span access location length along the axial length of rotor pilum, are 41%～45% of rotor pilum diameter along the circumferential width of rotor pilum, are arranged in the two ends of rotor pilum upper rotor part working position respectively, irrotationality to.
The lead angle of described long rib body is 55 °～60 °.
The beneficial effects of the utility model are shearing, the kneading dynamics that strengthened sizing material, enhance productivity, and promote the sizing material quality, and the wearing and tearing that slowed down rotor nog in the prolonging overhaul time limit, reduce cost of equipment maintenance.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is an A-A direction cutaway view among Fig. 1.
Be labeled as among the figure: 1-rotor pilum, 3-top faceted pebble, 4-incline face, the long rib body of 7-, the short rib body of 8-.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, rubber and plastic banbury meshing rotor comprises a pair of rotor, and rotor pilum 1 outer surface of each rotor is provided with the rib body, and described rib body is 41%～50% of rotor pilum 1 diameter along the width on the rotor pilum 1 outer surface circumference.The rib body of existing relatively rotor, the rib body of rotor of the present utility model is strengthened greatly along circumferential width, a pair of rotor in the running is meshing with each other, rotating speed is identical, the top faceted pebble 3 of one of them rotor is pressed close to mutually with the outer surface of the rotor pilum 1 of another rotor, the centre is left a fixed gap and is held sizing material, since the outer surface of top faceted pebble 3 and rotor pilum 1 apart from distance of center circle from different, thereby linear velocity difference, sizing material is therebetween rubbed, increase the working face of friction, strengthened the frictional heat effect of sizing material.Simultaneously the sizing material in 4 in the incline face of the incline face 4 of a rotor and another rotor also is squeezed and rubs, and has alleviated the workload of seamed edge on the rib body so on the whole, has reduced the wearing and tearing of seamed edge.
Described rib body is at least two sections, and the rib body of one of them rotor engages between the rib of another rotor, and the top faceted pebble 3 of rib body has the gap with the outer surface of another rotor pilum 1, has the gap between the incline face 4 of two rib bodies that are meshed.Along rotor pilum 1 multistage rib body can be set, with the velocity gradient on the incline face 4 of the right linear differential of the top faceted pebble 3 of a plurality of rib bodies and rotor pilum 1 outer surface, the rib body that is meshed sizing material is rubbed, pushes, increase rubbing surface as far as possible, improve frictional heat efficient.
Because the space of the banburying chamber of existing banbury is limited, guarantee that under the situation of rib body top faceted pebble 3 width, the rotor with long rib body can't cooperate the space of banburying chamber, in order to make compact conformation, kneading is effective.The preferred scheme of the utility model is that described rib body is three sections, comprises a long rib body 7 and two short rib bodies 8 that are interspersed with long rib body 7.
In order to obtain optimized kneading effect, described long rib body 7 equals 3/4～3/5 of working rotor span access location length along rotor pilum 1 axial length, along rotor pilum 1 circumferential width is 45%～50% of rotor pilum 1 diameter, and the subbase post 1 outer surface helical form that rotates is arranged; Article two, lacking rib body 8 is 1/3～1/2 of working rotor span access location length along rotor pilum 1 axial length, along rotor pilum 1 circumferential width is 41%～45% of rotor pilum 1 diameter, be arranged in the two ends of rotor pilum 1 upper rotor part working position respectively, irrotationality to, be interspersed with long rib body 7.Wherein the working rotor span access location length is the length that rotor is positioned at banburying chamber.Synchronously in the rotation process, the rib body of two rotors cooperatively interacts, and its shape is suitable and leave a fixed gap, in order to hold sizing material and by rotating wherein sizing material to be pushed, rubs, make mechanical energy be converted into heat energy, cooperate the chemical assistant that adds wherein to make the desulfurization regeneration of sizing material.
As preferred implementation of the present utility model, the lead angle of described long rib body 7 is 55 °～60 °, can obtain kneading effect preferably, does not influence material feeding speed simultaneously.
