The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the utility model comprises shaft 3 and is installed in many groups opposed type agitating unit on the shaft 3 from left to right successively that shaft 3 and opposed type agitating unit mounted thereto are formed the opposed type stirring structure that material is promoted to stir continuously.Described opposed type agitating unit comprise two structures all identical with size and symmetrical be installed in shaft 3 up and down or the orthoscopic mixing arm of both sides, front and back all identical with two structures and be installed in the stirring vane of two mixing arm ends respectively with size, the stirring face of described stirring vane is that plane and two stirring vanes direction that promotes the material axially-movable is identical.Angle between adjacent two mixing arms is 90 °, and it is that the axial established angle of stirring vane is 30 °～45 ° that the stirring face of described stirring vane and its are installed angle between the mixing arm axis.In the present embodiment, described many group opposed type agitating units are even laying.To sum up, for an opposed type agitating unit, the orthoscopic mixing arm coaxial line that two structures are all identical with size is installed in shaft 3 both sides and two mixing arms are specially mixing arm 1 and mixing arm 24, and mixing arm 1 and mixing arm 24 ends are separately installed with stirring vane 1 and stirring vane 25, and the axial setting angle of stirring vane 1 and stirring vane 25 is 30 °～45 °.Described stirring vane 1 has identical structure and size with stirring vane 25, and the direction of promotion material axially-movable is identical.When shaft 3 when the ω direction is rotated, stirring vane 1 will promote material along circumferential Z
1Direction motion, stirring vane 25 also will promote material along circumferential Z
1The direction motion, but they promote material again axially along X simultaneously
1The direction motion.Thereby for singly putting the formula agitating device, its shaft circles, and stirring vane promotes material movement for once, and its shaft of opposed type circles, and it is twice that stirring vane promotes material movement accordingly.
In conjunction with Fig. 4, in the twin-shaft mixer, the quantity of described opposed type stirring structure is two shafts, 3 parallel mixing drum 9 inside that are laid in of two and two opposed type stirring structure correspondences, described two shafts 3 are respectively shaft one 3-1 and shaft two 3-2, the left part of shaft one 3-1 is connected with driving mechanism is coaxial by shaft coupling 7, connects by synchronous drive mechanism between the left part of shaft one 3-1 and shaft two 3-2 and the right part of the two all is installed on the cylindrical shell of mixing drum 9 by bearing.Be installed on the shaft one 3-1 rightmost side the opposed type agitating unit stirring vane by with the stirring material be pushed into that the opposed type agitating unit that is installed on the shaft two 3-2 rightmost sides continues to stir return blade one 10-1, the axial established angle that returns blade one 10-1 is corresponding with the axial established angle of the stirring vane that is installed on shaft two 3-2 rightmost side opposed type agitating units; Be installed on the shaft two 3-2 leftmost sides the opposed type agitating unit stirring vane by with the stirring material be pushed into that the opposed type agitating unit that is installed on the shaft one 3-1 leftmost side continues to stir return blade two 10-2, the axial established angle that returns blade two 10-2 is corresponding with the axial established angle of the stirring vane that is installed on shaft one 3-1 leftmost side opposed type agitating unit.Described two opposed type stirring structures are formed a complete stirring system that material is circulated and stirs in mixing drum 9 inside.In the present embodiment, described driving mechanism is a reducing motor 6, and described synchronous drive mechanism is a synchromesh gear transmission device 8, and described bearing is installed in axle head bracing or strutting arrangement 11 inside.
To sum up, described twin-shaft mixer is made up of reducing motor 6, shaft coupling 7, synchromesh gear device 8, mixing drum 9, axle head bracing or strutting arrangement 11 and two opposed type stirring structures being installed in mixing drum 9 inside.In two opposed type stirring structures, two shaft that is arranged in parallel one 3-1 and shaft two 3-2 are fixedly connected on the mixing drum 9 by axle head bracing or strutting arrangement 11, reducing motor 6 connects synchromesh gear device 8 by shaft coupling 7, and synchromesh gear device 8 is connected with shaft two 3-2 with shaft one 3-1 respectively.Simultaneously, the a plurality of mixing arms that are installed on shaft one 3-1 and shaft two 3-2 all fixedly mount by the helical arrangement form, in the present embodiment, stirring vane all is fixedly connected on the end of mixing arm with 45 ° axial established angle, return blade one 10-1 and return blade two 10-2 and be fixedly connected on the mixing arm end with 45 ° axial established angle equally, return blade one 10-1 and return normal direction that blade two 10-2 stir face along the projection of the shaft 3 axis inwall of the left and right sides end face of mixing drum 9 dorsad.In the actual whipping process, the phase difference between two shafts, one 3-1 and shaft two 3-2 is 45 °.In mixer when work,, reducing motor 6 drives shaft one 3-1 and shaft two 3-2 rotate in opposite directions, and material circulates in mixing drum 9 with returning blade one 10-1 and return under the promotion of blade two 10-2 at stirring vane.Simultaneously, because many group opposed type agitating units all are installed on the every shaft, thereby under the promotion of stirring vane, make the stirring vane number of every shaft participation work increase, the number of times that material is stirred increases within a certain period of time, thereby accelerated the frequency of material axial circulation, thereby improved mixing quality and stirring efficiency.
Below by test existing conventional agitating device is promptly singly put formula agitating device and opposed type agitating device described in the utility model mixing effect compare, it is identical singly to put the used mixing speed of formula agitating device and opposed type agitating device in the test, but the mixing time of singly putting the formula agitating device is 28s, and the mixing time of opposed type agitating device is 24s.After two kinds of agitating devices stirred end, it was as shown in table 1 to test the bitumen content that draws each finished product material:
The comparative test result of table 1 bitumen content deviation
As shown in Table 1, different mixing under the arm arrangement form, the bitumen content of each finished product material has certain difference, and the standard deviation and the deviation of singly putting the formula agitating device are bigger than opposed type agitating device.
After two kinds of agitating devices stirred end, it was as shown in table 2 to test the comparative test result that draws each finished product material mineral aggregate gradation:
The comparative test result of table 2 finished product material mineral aggregate gradation
As shown in Table 2, the mineral aggregate gradation standard deviation of each finished product material exists certain difference, and the standard deviation of singly putting the formula agitating device is also bigger than opposed arrangement.Obviously, the opposed type agitating device is compared with singly putting the formula agitating device, because its increased frequency that material is stirred, thereby be more conducive to the even distribution of material in mixing tube, improved mixing quality and efficient.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; everyly any simple modification that above embodiment did, change and equivalent structure are changed, all still belong in the protection domain of technical solutions of the utility model according to the utility model technical spirit.
