Abstract
The utility model discloses a rotor of internal mixers, which is composed of a rotator long edge, a rotator short edge, a rotor body, and a circulating cooling water channel on a rotor communicated inner cavity. The utility model is characterized in that the rotator long edge and the rotator short edge are formed into a set of edges; two sets of edges are uniformly distributed on the rotor body; the two sets of edges extend from the end head of the rotor to the central position of the rotor spirally; the initial side of the long edge is not connected with the end head of the rotor; the initial side of the short edge is connected with the end head of the rotor; the wall and the edge of the rotor communicated inner cavity are provided with the rotary circulating cooling water channel. The rotor has the advantages of axial force balance, few heat quantities, full mixing, fast curing system distribution, big filled coefficient, and obvious cooling effect during operation. Thus, the rotor can raise the quality of mix rubber refining and the efficiency of rubber refining. The utility model is an ideal rotor of internal mixers for rubber industries.
Description
Invention of the present utility model has related to a kind of closed-smelting machine rotor, especially a kind of rubber industry banbury four prismatic rotors.
The employed four prismatic rotors of existing closed-smelting machine rotor, its lug, nib adopt by helically shaped two the long ribs of dextrorotation of two ends of working rotor part and two left-handed short ribs and extend and form to the centre.During the working rotor of this kind form, evenly mixing effect is undesirable, and produces too much heat, causes the temperature rise of sizing material, mix quality and refining glue efficient have been influenced, and, cause integral casting process difficulty height because of complex contour and irregular, also can not process because of its inner chamber, can only adopt the spray type of cooling, make the rotor cooling condition poor, the cooling of rib top is bad, and then has influenced the thermodynamic property of sizing material.
The purpose of the present utility model provides a kind of novel closed-smelting machine rotor, can improve the quality of elastomeric compound and improve refining glue efficient when mixing work, and can realize rotor internal cavity is carried out machining.
In order to achieve the above object, invention of the present utility model is adopted and is formed one group of rib by a long rib and a short rib, and two groups of ribs that are evenly distributed on two sides of rotor are extended to the rotor center position from the two ends of rotor respectively, as Fig. 1,2.The initial line that rises of long rib is not connected with rotor end-face, only allows the initial line that rises of short rib be connected with rotor end-face, as Fig. 1,2.Because the lug, nib of rotor evenly distributes, therefore make rotor when casting, can form a kind of through inner chamber, and can be processed into circulating water-cooling structure.As Fig. 3,4.
The advantage of invention of the present utility model is: 1. suffered axial force can reach balance during working rotor, can not produce more heat, can keep lower glue furnacing temperature, thereby can produce very high shear stress, and it is faster that vulcanizing system is evenly distributed.2. rotor transports sizing material from the center beginning, and every rotor is carried sizing material to both sides individually, thereby is forming strong materials flow near two ends, mixing chamber, makes sizing material can not form the corner accumulation at rotor cylinder and rib end, and it is sufficient mixing that sizing material has been obtained.3. the long rib of rotor plays initial line and has played current divider, it is split into two parts with sizing material, and a part is sheared between rotor rib top and banburying locular wall, and another part is then by kneading constantly with turn over and smash, therefore obtain the effect of uniform mixing enhancing, thereby improved mixing quality.4. during working rotor, long rib does not produce elevated pressures, so activity coefficient can increase, promptly the sizing material that is refined in the banburying chamber can be more more, thereby has just improved the efficient of refining glue yet.5. because the circulation cooling can be implemented in rotor internal cavity and rotor lug, nib position, thereby significantly improved the cooling effect of rotor, made the thermodynamic property of sizing material obtain very big optimization.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a front view of the present utility model.
Fig. 2 is an expanded view of the present utility model.
Fig. 3 is an elevation cross-sectional view of the present utility model.
Fig. 4 is a side cutaway view of the present utility model.
The working rotor partial-length is L, L=1.45～1.70D; D is the maximum rotating diameter of working rotor part.
By Fig. 1,2 as can be known, embodiment of the present utility model is by rotor block [1] and evenly long rib [2], [4] and short rib [3], [5] of its two sides of distribution are formed, on the two sides of rotor block [1], extend to the rotor center position from rotor tip position separately with helical form long rib [2], [4] and short rib [3], [5], short rib [3] and [5] originates in two ends [6] and [7] of rotor block [1], the distance that plays initial line and rotor block termination [7] and [6] maintenance 0.175L of long rib [2] and [4], the lead angle of long rib [2] and short rib [3] is that 41 ° of directions are dextrorotation; The lead angle of long rib [4] and short rib [5] also is 41 °, and direction is left-handed.The length of long rib [2] and [4] is 0.65L, and the length of short rib [3] and [5] is: 0.22L.Structure links to each other with rotor block [1] with the curved surface form at the bottom of the rib, as Fig. 4.
Show that as Fig. 3,4 embodiment rotor block of the present utility model [1] becomes a through inner chamber after cast form, be connected and integral body of rotor formation through set bolt [6] with armature spindle [2] cooperation during assembling.Inner wall position at internal chamber wall and lug, nib position, form swinging circulation water channel [1] through machining, through cooperating with the inlet opening [5] and the apopore [4] of armature spindle [2], make from the next cooling water of intake-outlet [3] and rotor is realized the forced circulation water cooling, thereby improved the cooling effect of rotor greatly through circulation water channel [1].
Closed-smelting machine rotor of the present utility model has not only improved mix quality and refining glue efficient, and the casting technique of rotor is simplified, and has guaranteed the castability of rotor, is a kind of more satisfactory rubber industry closed-smelting machine rotor.
