Description

Technical Field

[0001] This utility model relates to the field of modified asphalt technology, specifically a modified asphalt heating device. Background Technology

[0002] Modified asphalt is an asphalt binder made by adding external admixtures (modifiers) such as rubber, resin, polymer, finely ground rubber powder, or other fillers, or by taking measures such as slight oxidation processing of asphalt, so as to improve the performance of asphalt or asphalt mixture. There are two mechanisms for modified asphalt: one is to change the chemical composition of asphalt, and the other is to make the modifier evenly distributed in the asphalt to form a certain spatial network structure. Existing modified asphalt heating devices only use a stirring rod for simple stirring, which has poor stirring effect, low efficiency, and is not convenient for movement and unloading, thus bringing great inconvenience to the heating work.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model involves adding raw materials into the inner cavity of a heating liner and then activating an external power supply to power the heating coil. This heats the inner liner, melting the raw materials. Simultaneously, a drive motor rotates a driving gear, which in turn rotates a driven gear, which in turn rotates a rotating shaft. This rotating shaft causes the inner liner to rotate clockwise, thus rotating the raw materials. Simultaneously, a servo motor drives a stirring rod to rotate counter-clockwise, stirring the raw materials. The counter-rotating heating liner and stirring rod ensure efficient and rapid mixing, improving mixing efficiency. After melting, the retraction of a hydraulic telescopic rod tilts the heat-insulating outer shell forward, while the servo motor-driven stirring rod quickly discharges the melted raw materials. This equipment achieves efficient and rapid heating, mixing, and stirring, ensuring effective mixing while also enabling efficient and rapid unloading without clogging, greatly facilitating the preparation of modified asphalt.

[0012] 2. This utility model can better move the equipment by setting universal wheels, lock the universal wheels by setting brake pads to better ensure the stability of the equipment, realize automated control of the equipment by setting controller, ensure that the equipment can continue to work for a period of time when power is cut off by setting battery, and prevent asphalt from adhering to the surface of the equipment by setting anti-stick coating.
