Description

Planetary stirrer

Technical Field

The invention relates to a stirrer arranged in an asphalt tank and used for stirring asphalt, in particular to a stirrer suitable for production of high-viscosity asphalt such as rubber asphalt or SBS high-content modified asphalt and the like, and belongs to the technical field of stirring equipment.

Background

In the asphalt industry, asphalt stirrers play a very important role, and if the stirrers can be effectively utilized, energy can be saved and the asphalt production efficiency can be improved. Such as: stirring is added in the heating process of the matrix asphalt, so that about 70 percent of heating time can be shortened, and the heat demand on asphalt heating is reduced; and stirring is added in the development process of the modified asphalt, so that the development time can be reduced from 8 hours to 2-3 hours.

At present, the stirrer used in the asphalt industry mainly has two forms, one is a stirrer with a blade on a common main shaft, the stirring capacity is stronger because the blade rotates at an inclined angle, but the stirrer always has a place which can not be stirred because of the limitation of the length of the blade, is suitable for a stirring tank with low requirements, and is widely applied; the other is a frame stirrer, wherein the frame is fixedly connected with the main shaft and rotates along with the main shaft, the stirring range is large, but the gap of the frame is large and the turnover angle is not formed, so that the stirring effect is general, and the frame stirrer is mainly suitable for stirring liquid with low viscosity.

The main motion process of the invention is as follows:

the power output device drives the main shaft 11 to rotate, the main shaft blades 12 rotate along with the rotation and stirring, meanwhile, the stirring frame 13 fixedly connected with the main shaft 11 also rotates, and the planet shaft 7 arranged on the stirring frame 13 also revolves around the main shaft 11; because the gear B8 on the planet shaft 7 is meshed with the gear A9 or the large gear ring which is relatively fixed and rotates, the planet shaft 7 also rotates while revolving around the main shaft 11, and the fixedly connected planet shaft paddle 6 also rotates and stirs; the rotation speed of the planet shaft 7 depends on the transmission ratio of the gear A9 to the gear B8, if the transmission ratio is 1, the planet shaft 7 rotates for 1 week while revolving for 1 week, if the transmission ratio is more than 1, the planet shaft 7 rotates for 1 week while revolving for more than 1 week, otherwise, the rotation speed is less than 1 week; if the gear wheel b 8 on the planet shaft 7 meshes with the big gear ring, the rotation speed of the planet shaft 7 is also determined by their transmission ratio.

The planetary stirrer can effectively stir high-viscosity asphalt or high-viscosity composite asphalt such as rubber asphalt or high-content modified asphalt, can improve the stirring effect and the production efficiency of the composite asphalt, and has outstanding practicability and obvious economic value.
