Detailed description of the invention
Defer to technique scheme, as shown in Figure 1 to Figure 3, a kind of granulated crumb rubber asphalt mixture mixing device, comprise support 1, be arranged on the mix bucket 2 on support 1, mix bucket 2 be provided with the first charging aperture 4 and discharging opening 8, the axis direction of described mix bucket 2 and the angle of vertical direction are acute angle, mix bucket 2 axle center place is provided with the second head tank 3, second head tank 3 and is arranged in mix bucket 2 and sidewall is connected with the distribution box 9 of sieve aperture 13 with one; Distribution box 9 is connected with the shaft 10 with blade, shaft 10 and mix bucket 2 are by being arranged on the different motor-driven rotation on support 1.
The operation principle of this programme is such:
Rubber asphalt can improve the serviceability of tack coat, alleviates the aging of pitch, increases the service life, therefore carried out in the lab studying widely.For the mix process of rubber grain and pitch, different from the mix process of pitch and common material, rubber has viscosity after high temperature melting, easy conglomeration, and traditional asphalt mixing plant is single shaft monotubular, when rubber grain pours mix bucket 2 into simultaneously, rubber grain collective will be produced and melt, form agglomerate, even have influence on the rotation of shaft 10.
Be directed to this problem, the thinking of solution is, first, rubber grain should be allowed to enter into the pitch of mix bucket 2 constantly, equably, make it slowly melt, easier mix; Secondly, rubber grain and pitch should be allowed to have contact area and stir area widely, be convenient to like this make rapidly rubber melt, the contact agglomeration between minimizing rubber.
For this, the second head tank 3 structure is provided with in this programme, this feeding cylinder is for adding rubber grain, rubber grain enters in distribution box 9 by the second head tank 3, with sieve aperture 13 on the sidewall of distribution box 9, the diameter of sieve aperture 13 slightly larger than the diameter of rubber grain, when so driving distribution box 9 to rotate, rubber grain in distribution box 9 will constantly, from sieve aperture 13, spreading out, drops in the pitch in mix bucket 2 equably; This process can complete automatically, makes mix process be more prone to convenient.
And the angle of the direction of axis line of mix bucket 2 and vertical direction is acute angle, the surface of such pitch in mix bucket 2 is exactly oval, but not circle when mix bucket 2 is vertically placed.Under such circumstances, rubber grain in distribution box 9 drop into mix bucket 2 medium pitch surface time, by dispersion evenly, have larger area and Asphalt Contactor, the probability that rubber grain contacts each other diminishes, and the Contact that effectively prevent rubber grain melts the unity phenomenon occurred.
In addition, be provided with two cover rotating mechanisms, drive respectively with different motors, a motor drives shaft 10 to rotate, and the blade on shaft 10, to compound uniform stirring, drives distribution box 9 to rotate simultaneously; Another motor drives mix bucket 2 to rotate, such mix bucket 2 both can with shaft 10 rotating Vortex, can reversely rotate with mix bucket 2 again, make whipping process more evenly, efficient.
As made this programme performance more excellent, on the basis of aforementioned schemes, following technological means can be added further:
Further, the axial line of described mix bucket 2 and the angle of vertical direction are 30 ° ~ 60 °.
The axis direction of mix bucket 2 and the angle of vertical direction should not be excessive, also unsuitable too small, through test of many times, determine to be advisable at 30 ° ~ 60 °, are preferably 45 °.
The outside of mix bucket 2 is evenly distributed with oil guide pipe 11.
In order to be beneficial to mix process, need to ensure that pitch mineral aggregate and rubber grain are in the condition of high temperature all the time in mix process, be beneficial to whipping process, therefore oil guide pipe 11 is preferably set in mix bucket 2 outside, pumped into by deep fat in pipe, the conduction also by mix bucket 2 in mix process carries out homogeneous heating to the material stirred.
One comparatively reasonably shaft 10 set-up mode is:
One end of shaft 10 is connected to bottom distribution box 9, and the other end of shaft 10 passes mix bucket 2 and is connected with the first motor 7 be arranged on support 1.
Shaft 10 is preferably connected to distribution box 9 lower center position, makes can not rock in distribution box 9 rotation process, and around its axis rotation, the rubber grain of such spreading will be more even.
Support 1 is provided with the second motor 6, mix bucket 2 outer setting has the sleeve 12 with external gear, and external gear and the driving gear be arranged on the second motor 6 output shaft of sleeve 12 coordinate.
Owing to will arrange two motors, and shaft 10 is positioned at the axle center place of mix bucket 2, so just needs the setting position relation of consideration two motors.
First motor 7 coaxially can be arranged with shaft 10, but the second motor 6 is due to the restriction of the first motor 7 position, the position identical with the first motor 7 can not be placed on, therefore sleeve 12 structure can be adopted, sleeve 12 barrels of axle center are arranged on bottom mix bucket 2, inner hollow, shaft 10 passes from sleeve 12; And sleeve 12 outside connects the second motor 6 by the mode that gear coordinates, the position that such second motor 6 can be placed on the first motor 7 side is rotated to drive mix bucket 2, and two motors are independent of each other mutually.
This mixing device also comprises base 5, and support 1 is cemented on base 5.
Because mix bucket 2 is eccentric rotary, consider its stability problem, more stable base 5 should be had, therefore a plate shape base 5 should be set, enlarge active surface, more stable when mix bucket 2 is rotated.
Second head tank 3 due to and mix bucket 2 between be separate two cover rotation systems, therefore in order to not affect both mutual rotations, the mode of bearing can be adopted to connect.
In one embodiment, utility model works step is as follows:
1. add rubber grain to the second head tank 3, add mineral aggregate to the first charging aperture 4, start the first motor 7 and the second motor 6;
2., by oil guide pipe 11 pairs of asphalt heatings, heating-up temperature is that mix is temperature required;
After 3.40 seconds, the pitch of heating is passed into mix bucket 2 by the first charging aperture 4 together with breeze;
4., after mix completes, extract asphalt from discharging opening 8.
