Description

Technical Field

[0001] The utility model relates to the technical field of asphalt production equipment, in particular to a modified asphalt stabilizer adding device. Background Art

[0002] Modified asphalt is a performance-optimized asphalt mixture created by adding modifiers such as rubber, resin, polymers, or other fillers to asphalt. Due to its excellent elasticity, flexibility, and wear resistance, modified asphalt is widely used in road and building construction. The production process of modified asphalt often requires the addition of stabilizers (such as sulfur) to alter the asphalt's physical and chemical properties, improving its stability and durability, thereby enhancing the road's load-bearing capacity and durability.

[0003] A large amount of stabilizer needs to be added during the production process, and workers usually add the entire bag of stabilizer directly into the production tank when adding materials. This is not conducive to breaking up the stabilizer inside the tank body and mixing it evenly into the modified asphalt, which makes the quality of the modified asphalt worse. Moreover, the manual addition of stabilizers carries the risk of stabilizers escaping into the air and being inhaled by workers, posing a threat to their health.

[0004] Therefore, it is necessary to invent a modified asphalt stabilizer adding device to solve the above problems. Utility Model Content
