Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of asphalt stirring, in particular to a modified asphalt stirring mill. Background Art
[0002] With the increase in traffic volume and the diversification of road conditions, traditional asphalt materials can no longer meet the needs of modern road construction. Modified asphalt is needed to improve the durability, stability and deformation resistance of roads. The development of modified asphalt technology, including polymer modification, fiber reinforcement, surfactant addition, etc., can significantly improve the performance of asphalt, but requires specific mixing equipment to achieve uniform mixing. Traditional asphalt mixing equipment cannot meet the mixing requirements of modified asphalt. More efficient mixing equipment is needed to ensure uniform dispersion of modifiers and asphalt, which has promoted the development of modified asphalt mixing mill technology.
[0003] In actual use, a mixing mill without a rolling wheel may not be able to fully crush and mix the asphalt and modifiers, resulting in insufficient uniformity of the mixture. Modifiers such as polymers and fibers need to be evenly dispersed in the asphalt. A mixing mill without a rolling wheel and sieve holes may not be able to effectively disperse these modifiers. The rolling wheel and sieve holes help to improve the mixing efficiency and screening efficiency. The absence of these components may lead to reduced production efficiency. The uniformity and particle size distribution of the mixture have an important impact on the bearing capacity, durability and stability of the road. The absence of a rolling wheel and sieve holes may lead to a decline in road performance. Utility Model Content

The outer ring of the first rotating shaft is fixedly connected to the "C"-shaped stirring rod, ensuring the stability of the stirring rod during high-speed rotation and preventing deviation or vibration caused by centrifugal force. The rolling wheel fixedly connected to the outer ring of the support plate can grind the asphalt material to achieve material refinement, which helps to improve the dispersion and mixing uniformity of the asphalt. The sieve hole design at the upper and lower ends of the fixed block allows the asphalt material to be continuously screened during the mixing process, which helps to separate asphalt of different particle sizes and ensure the particle size consistency of the final product.
[0005] To achieve the above-mentioned object, a modified asphalt stirring mill is provided, comprising: a tank body, a first rotating shaft passing through the interior of the tank body, a "C"-shaped stirring rod fixedly connected to the outer ring of the first rotating shaft, a support plate fixedly connected to the bottom end of the first rotating shaft, a rolling wheel fixedly connected to the outer ring of the support plate, a fixed block rotatably connected to the rolling wheel, and the fixed block is fixedly connected to the interior of the tank body, and sieve holes are formed at the upper and lower ends of the fixed block;
