The course of work of this aggregate metering system is described below in conjunction with Fig. 4-Figure 11:
Driver element 4092 drives dispensing shaft 4091 to turn clockwise, angle stroke sensor senses that dispensing shaft 4091 stops dispensing shaft 4091 to rotate when rotating to the first predetermined angular, now the first blowing end 4093 is opened, and the first aggregate is connected aggregate connection storehouse 402, storehouse 401, second, the 3rd aggregate connects storehouse 403, the 4th aggregate connects storehouse 404 and the aggregate in the 5th aggregate connection storehouse 405 is discharged to the first measuring chute 406 successively.Premix stirring motor 4081 in the first measuring chute 406 drives premix agitator 4082 pairs of aggregates to stir in advance, then the aggregate after pre-stirring drops into agitated kettle 411 and stirs, driver element 4092 drives dispensing shaft 4091 to be rotated counterclockwise to the second predetermined angular simultaneously, second blowing end 4094 is opened, and the first aggregate is connected aggregate connection storehouse 402, storehouse 401, second, the 3rd aggregate connects storehouse 403, the 4th aggregate connects storehouse 404 and the aggregate in the 5th aggregate connection storehouse 405 is discharged to the second measuring chute 407 successively and carries out premix stirring.Pot 411 to be mixed stirs the aggregate of complete first measuring chute 406, the aggregate of the second measuring chute 407 is dropped into agitated kettle 411 stir, the aggregate that simultaneously the first measuring chute 406 proceeds to connect that storehouse 401, second aggregate connects storehouse 402, the 3rd aggregate connects storehouse 403, the 4th aggregate connects storehouse 404 to the first aggregate and the 5th aggregate connects storehouse 405 carries out cumulative measurement, weighs with this cycle alternation.
The aggregate metering system of the embodiment of the present invention, by arranging the first measuring chute 406 and the second measuring chute 407 is alternately weighed to aggregate, can utilize the second measuring chute 407 pairs of aggregates to weigh after the first measuring chute 406 pairs of aggregates are weighed at once.A measuring chute is only had to carry out cumulative measurement to aggregate compared to existing technology, when aggregate kind is more, there will be agitated kettle and complete stirring, and measuring chute does not also complete Weighing, agitated kettle is in idle state, production technology continuity is bad, thus causes the productivity ratio of whole manufacturing process very low, and the embodiment of the present invention can improve measurement efficiency.The embodiment of the present invention is also provided with premix stirring device in the first measuring chute 406 and the second measuring chute 407, further reduces agitated kettle mixing time, improves production efficiency.Furthermore, the present embodiment also adopts segmented dispensing shaft 4091, can carry out blowing respectively, having saved cost when not increasing driver element to the first measuring chute 406 and the second measuring chute 407.
The embodiment of the present invention also provides a kind of asphalt mixing plant, and this asphalt mixing plant comprises aforesaid aggregate metering system, and other structures of this asphalt mixing plant please refer to prior art, do not repeat them here.
By the way, aggregate metering system of the present invention and asphalt mixing plant are alternately weighed to aggregate by arranging two measuring chutes, and carry out premix stirring before aggregate drops into, and shorten the mixing time of agitated kettle, the embodiment of the present invention can improve measurement efficiency, enhances productivity.
Refer to Figure 14, Figure 14 is the schematic flow sheet of asphalt mixing method embodiment of the present invention.This asphalt mixing method comprises:
Step S1401: utilize the hocket Weighing of aggregate premix of the first measuring chute and the second measuring chute to stir.
Wherein, aggregate is stored in multiple aggregate according to different-grain diameter size and connects in storehouse, and the first measuring chute and the second measuring chute interval are arranged, and all have premix stirring device, to stir in advance aggregate before input agitated kettle, shorten the mixing time of agitated kettle.
Specifically, refer to Figure 15, Figure 15 is that the first measuring chute of asphalt mixing method embodiment of the present invention and the second measuring chute hocket the idiographic flow schematic diagram that the Weighing of aggregate premix stir.When embody rule, the hocket Weighing of aggregate concrete steps that premix stirs of the first measuring chute and the second measuring chute comprise:
Step S1501: in first time period, utilizes the first measuring chute to carry out Weighing to aggregate.
In the present embodiment, adopt foregoing segmented dispensing shaft, the first measuring chute and the second measuring chute can not Weighings simultaneously.
Step S1502: in the second time period, utilizes the first measuring chute to carry out premix stirring to the aggregate after Weighing, utilizes the second measuring chute to carry out Weighing to aggregate simultaneously.
When aggregate kind is more, the time may carrying out Weighing to aggregate is greater than the time that premix stirs, and the aggregate after now premix can being stirred drops into agitated kettle.
Step S1503: in the 3rd time period, utilizes the first measuring chute to carry out Weighing to aggregate, utilizes the second measuring chute to carry out premix stirring to the aggregate after Weighing simultaneously.
Wherein, the aggregate dropping into agitated kettle is carried out stirring and forms finished product material, and discharging is to storage silo.Similar with step S1502, the second measuring chute may be less than to the time that the aggregate after Weighing carries out premix stirring the first measuring chute to carry out Weighing time to aggregate, and now, the aggregate after being stirred by premix drops into agitated kettle.
Step S1504: the step repeating the second time period and the 3rd time period.
Step S1402: the aggregate after being stirred by premix drops into agitated kettle, and utilizes agitated kettle to stir to form finished product material to aggregate.
The asphalt mixing method of the embodiment of the present invention carries out alternately Weighing by two measuring chutes to aggregate, a measuring chute is only had to carry out Weighing to aggregate compared to existing technology, when aggregate kind is more, cannot meet need of production because measurement efficiency is low, the asphalt mixing method of the embodiment of the present invention can improve measurement efficiency.Further, before aggregate drops into agitated kettle, premix stirring is carried out to aggregate, shorten the mixing time of stirring, thus improve the production efficiency of whole manufacturing process.
The foregoing is only embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize manual of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
