Description

Technical Field

[0001] The utility model relates to the technical field of asphalt production equipment, and more specifically to a modified asphalt development tank. Background Art

[0002] Modified asphalt refers to an asphalt material whose physical properties and performance are altered by adding specific modifiers. A modified asphalt development tank is a device used to heat and mix modified asphalt. It typically consists of a large-capacity tank and a heating system. Its primary function is to mix the original asphalt and modifier and heat them to the required temperature to achieve a thorough mixing and reaction between the modifier and the asphalt. Within the development tank, the asphalt and modifier remain for a certain period of time, allowing them to fully mix and react, resulting in the desired modified asphalt.

[0003] Chinese utility model patent CN213739296U discloses a high-efficiency modified asphalt development tank, including a development tank body, a rotating motor fixedly connected to the center of the top of the development tank body, a rotating rod fixedly connected to the output end of the rotating motor, the bottom of the rotating rod passes through the development tank body and extends to the bottom of the inner cavity of the development tank body, and the outer surface of the rotating rod is evenly fixedly connected to a stirring rod. The utility model can stir the asphalt by arranging a rotating motor, a rotating rod and a stirring rod, and can clean the modified asphalt adhered to the inner wall of the development tank body by arranging a turntable, a vertical rod, a scraper and a fixed rod, and can prevent blockage during discharge by arranging a spiral push plate. By arranging the above structure, the modified asphalt adhered to the tank wall of the development tank is easily cleaned, which solves the problem that a large amount of modified asphalt will adhere to the tank wall of the traditional development tank during use, which is difficult to clean and affects the next use, thereby ensuring the later production effect.

[0004] The above technical solution has the following problems: during the production process of modified asphalt, materials such as rubber, resin, high molecular polymer and ground rubber powder need to be added to the tank body, but the added materials are of different sizes, which will cause uneven mixing of the materials and asphalt. Larger materials may not be fully integrated into the asphalt, forming a granular mixture. These incompletely integrated materials will affect the performance of the asphalt in subsequent use, resulting in unstable road quality, such as local looseness and cracking. Utility Model Content
