Description

Technical Field

[0001] The utility model relates to the technical field of asphalt production and processing, in particular to an asphalt mixing device with rapid material discharging. Background Art

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It has waterproof, moisture-proof and anti-corrosion properties. Asphalt is widely used in construction projects such as pavement. The road surface paved with asphalt is smooth, wear-resistant and non-slip. It can withstand the heavy pressure of vehicles and frequent traffic flow. It also has good waterproof performance and can effectively protect the roadbed. In actual application, asphalt is used as the main raw material for paving asphalt roads. By adding admixtures such as rubber powder to asphalt, the performance of asphalt mixture can be improved, thereby effectively improving the quality of asphalt pavement and extending the service life of the pavement. Among them, when adding admixtures to asphalt, mechanical mixing devices are usually used to fully mix the admixtures and asphalt to improve the performance of asphalt mixture.

[0003] The utility model patent with the publication number of "CN215329175U" and the name of "A Rubber Powder Composite Modified Asphalt Mixing Device" discloses that heated asphalt and admixtures are added into a mixer, and the power mechanism drives the mixing shaft in the mixer to drive the blades to rotate so as to fully mix the asphalt and the admixtures. However, it still has some shortcomings. First, the mixing shaft drives the blades to rotate, and the blades can only stir the asphalt and the admixture horizontally. The asphalt and the admixture are mixed unevenly, and it is difficult to ensure the performance of the asphalt mixture, which will affect the road quality. Second, the powder of the crushed admixture is directly mixed into the asphalt from the feed port, and the dispersion is uneven. It takes a longer mixing time to achieve the purpose of uniform mixing, which increases production costs and wastes resources. In addition, the powder is easily agglomerated when mixed into the asphalt, which leads to uneven mixing and affects the performance of the asphalt mixture. Utility Model Content

[0004] The utility model aims to provide an asphalt mixing device with fast discharging, so as to solve the problems in the prior art of uneven mixing of asphalt and admixture, long mixing time, and easy agglomeration of admixture during mixing, which leads to high production cost, waste of resources, difficulty in ensuring the performance of asphalt mixture, and thus affects the quality of road surface.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A fast discharging asphalt mixing device, comprising:

[0007] A stirring tank body, wherein a feed inlet is formed at the top of the stirring tank body, and a discharge outlet is formed at the bottom of the stirring tank body;

[0008] A stirring assembly, the stirring assembly comprising a mounting rod and an L-shaped stirring frame, the mounting rod being rotatably mounted in the stirring tank body and arranged along the axial direction of the stirring tank body, and the L-shaped stirring frame being mounted on the mounting rod;

At the same time, the first driving device also drives the bulk material assembly to rotate through the mounting rod, so that when the admixture is added from the feed port, it is dispersed and evenly falls into the asphalt under the action of the bulk material assembly, thereby ensuring the mixing efficiency and quality of the asphalt and the admixture, preventing the admixture from agglomerating in the asphalt, affecting the performance of the asphalt mixture, and thus affecting the road surface quality.

Since the length of the first stirring main rod is greater than the length of the second stirring main rod, the distances between the first stirring auxiliary rod and the second stirring auxiliary rod and the mounting rod are different, so that the stirring range is wider, the stirring is more uniform, the stirring time is shortened, resources are saved, and the production cost is reduced. When working, the bulk material assembly is located above the first stirring main rod, and the first driving device drives the mounting rod to rotate, thereby driving the bulk material assembly, the first stirring main rod and the second stirring main rod to rotate.

The working efficiency is high, the mixing effect is good, the performance of the asphalt mixture is guaranteed, and thus the road surface quality is guaranteed.

[0014] Furthermore, the number of the first stirring main rods and the second stirring main rods are both more than two, and the first stirring main rods and the second stirring main rods are evenly distributed along the circumference of the mounting rod.

When the push plate rotates, it can also scrape the asphalt mixture attached to the bottom of the mixing tank body into the discharge port. At the same time, the push plate also drives the scraper to rotate, thereby scraping off the asphalt mixture attached to the side wall of the mixing tank body, so that the asphalt mixture in the mixing tank body is completely discharged, preventing the asphalt mixture from accumulating in dead corners such as the bottom and side walls of the mixing tank body, causing resource waste and cost savings.

[0024] Furthermore, the push plate is arranged in a fan shape along the radial cross section of the stirring tank body, and the scraper is arranged in an arc shape along the radial cross section of the stirring tank body.
