Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and detailed description of the invention of the present utility model is described.Wherein, identical parts adopt identical label.
Fig. 1 is the structural principle schematic diagram of a kind of modified bitumen attemperator according to a specific embodiment of the present utility model, in FIG, in order to graphic simplicity, first heated oil 5 and the second heated oil 6 represent with lines, shown in Figure 1, the utility model provides a kind of modified bitumen attemperator, it comprises, a vertical circle tube tank body 1, described tank body 1 is arranged on a foundation ditch 2, the first mixing device 3 of bottom and second mixing device 4 on top is provided with in described tank body 1, outside described first mixing device 3, described tank body 1 inwall is provided with the first heated oil 5, described tank body 1 top loop is provided with the second heated oil 6 around described second mixing device 4, described first mixing device 3 is not more than 1/3rd of the height of described tank body 1 with the height of described first heated oil 5.
Described tank body 1 is vertical columnar structured, and the modified bitumen that can be conducive to its storage inside can by uniform stirring and heating.
For modified bitumen manufacturer, described tank body 1 is larger, and the modified bitumen that can deposit is more, then its comprehensive operation cost is less, and such as, if described tank body 1 can deposit 150 modified bitumens, then its diameter can reach 5-8 rice, and height can reach 8-20 rice.
A kind of modified asphalt thermal insulation stirring cylinder provided due to the Chinese patent CN2490115Y of existing modified bitumen attemperator all as mentioned in background technology is similar, only be provided with a set of mixing device and heat riser, therefore, when small batch production modified bitumen, or when the modified bitumen stored in affiliated tank body 1 is less, then effective acting part of mixing device and heat riser is less, therefore easily causes electric energy and thermal waste, also improves operation cost.
In order to address this problem, the utility model is provided with described first mixing device 3 of bottom and described second mixing device 4 on top in described tank body 1, and corresponding described first mixing device 3 and described second mixing device 4 are provided with described first heated oil 5 and described second heated oil 6 respectively, like this, when small batch production modified bitumen, or when the modified bitumen stored in affiliated tank body 1 is less, only need to start described first mixing device 3 of bottom and described first heated oil 5, thus greatly can save the operation cost of described modified bitumen attemperator.
In order to arrange the motor for driving described first mixing device 3, described tank body 1 is arranged on a foundation ditch 2, can arrange the motor for driving described first mixing device 3 in described foundation ditch 2.Described first heated oil 5 is arranged along described tank body 1 inwall, manufacturing like this, also can keep the heat insulation effect of the modified bitumen bottom to described tank body 1 in addition preferably than being easier to.The pipeline of described first heated oil 5 lays and the pipeline similar with Chinese patent CN2490115Y can be adopted to lay mode.
