Description

Technical Field

[0001] This utility model relates to the field of asphalt equipment technology, and specifically to an asphalt mixture recycling device. Background Technology

[0002] Currently, most highways and urban roads in my country are asphalt pavements. Asphalt pavement refers to an asphalt mixture paved on the road surface, composed of crushed stone, sand, asphalt binder, and necessary additives. Compared to cement concrete pavements, asphalt pavements are flexible, offering a more comfortable ride and lower noise levels, hence the majority of existing road surfaces are asphalt. However, asphalt pavements are sensitive to temperature changes; high temperatures cause the asphalt to soften, while low temperatures cause it to become brittle. Under extreme temperature conditions, asphalt pavements are prone to cracking, deformation, and damage. Furthermore, asphalt pavements are flexible and require regular maintenance and repair. If the pavement condition is poor, milling the asphalt layer and repaving with new asphalt concrete is generally considered.

[0003] Asphalt can be mainly divided into three types: coal tar pitch, petroleum asphalt, and natural asphalt. Coal tar pitch is a byproduct of coking. Petroleum asphalt is the residue after crude oil distillation. Natural asphalt is stored underground, sometimes forming mineral layers or accumulating on the earth's surface. Asphalt is mainly used in industries such as coatings, plastics, and rubber, as well as for road paving. When roads are subsequently demolished and repaired, the pressed asphalt needs to be cleaned up. Existing treatment methods are as follows: 1. Direct disposal, which increases production costs and pollutes the environment; 2. Cold recycling, which involves directly adding waste asphalt mixtures to new liquid asphalt and other materials for regeneration and road paving, but the quality of the recycled mixture is low and its durability is poor; 3. Thermal recycling, which involves collecting and crushing waste asphalt mixtures, but the overall recovery rate is low, resulting in resource waste and environmental pollution. The overall physical properties of the recycled asphalt are greatly reduced, and direct use will result in substandard road surfaces. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0022] like Figure 1-3As shown, an asphalt mixture recycling device includes an installation plate 1, a conveying mechanism disposed on one side of the installation plate 1 for conveying old asphalt, and a mixing mechanism disposed on the other side of the installation plate 1. The mixing mechanism receives the old asphalt conveyed from the conveying mechanism and mixes the old asphalt with new asphalt to make them evenly mixed and melted to form asphalt material.

[0023] Specifically, as shown in the figure, the conveying mechanism includes a suspension frame 2 integrally disposed on the front end of the upper surface of the mounting plate 1. There are two symmetrical suspension frames 2, and each of them has an extension bracket 3 fixedly installed on its relative inner side. A first belt roller 4 is rotatably installed on the lower suspension end of the extension bracket 3. A pair of vertical mounting frames 12 are vertically and symmetrically arranged in the middle of the mounting plate 1. A second belt roller 5 is rotatably installed between the upper ends of the two vertical mounting frames 12. A transmission belt 6 is fitted between the first belt roller 4 and the second belt roller 5.

[0024] Specifically, as shown in the figure, the mounting plate 1 has a mounting port 11 on its rear side. The stirring mechanism includes a stirring cylinder 7 embedded in the mounting port 11. A carrier 14 is provided at the upper end of the stirring cylinder 7. A motor 13 is fixedly installed on the carrier 14. A stirring frame 17 is fixedly installed at the output end of the motor 13. The stirring frame 17 is located at the bottom of the stirring cylinder 7. A screen 18 is fixedly installed at the lower end of the stirring cylinder 7. A heat-insulating guide bucket 19 is also fixedly installed at the lower end of the stirring cylinder 7.

[0025] The frame effectively supports and installs the motor, the support column provides space for the top cover, the top cover effectively protects the motor, and effectively exhausts the flue gas produced by heating, preventing accumulation and the formation of air bubbles in the internal asphalt, which would affect its use.

[0026] By setting up a screen, the residence time of the mixed asphalt can be guaranteed, while ensuring the seepage of the melted asphalt. The heat-insulating guide bucket effectively collects, integrates, and discharges the seeping asphalt.

[0027] Specifically, as shown in the figure, the lower part of the stirring drum 7 is fitted with an electric heating ring 10, and the screen 18 is positioned horizontally below the electric heating ring 10.

[0028] The mixing drum is heated by an electric heating ring, and the recycled old asphalt mixture is mixed with new asphalt under the action of the mixing frame. This effectively modifies the recycled asphalt, improves its physical properties, and ensures that the road surface can be paved after reuse.

[0029] Specifically, as shown in the figure, the side wall of the mixing drum 7 is provided with a recovery port 8 and a new material port 9. The recovery port 8 is located below the second belt roller 5, and the new material port 9 is located above the recovery port 8, and the feeding directions of the two are at a 90-degree angle.

[0030] The lower end of the insulated guide hopper is located above the lower edge of the first belt roller. By setting a height difference, it is possible to avoid obstruction of material discharge after installation.

[0031] The new material inlet is located above the recycled material inlet, and the two feed directions are at a 90° angle, which ensures that the new material can be better mixed with the old asphalt after it is put in, and further improves the mixing efficiency.

[0032] Specifically, as shown in the figure, a support column is vertically welded to the upper end of the stirring cylinder, and a top cover is fixedly installed on the upper end of the support column.

[0033] Specifically, a driven pulley is fixedly installed on the side of the second belt roller 5. The driven pulley is connected to a power source via a belt, and power is introduced through the driven pulley to drive the device. The power source includes, but is not limited to, a diesel engine for on-site operation.

[0034] Specifically, the specific implementation process of this utility model is as follows:

[0035] Install the device and connect it to the power supply and power source;

[0036] After the power is turned on, the second belt roller drives the conveyor belt and the first belt roller to work, conveying the old asphalt to the mixing drum;

[0037] Old asphalt is introduced through the recycling inlet, while new asphalt is introduced into the mixing drum 7 through the new inlet;

[0038] The motor drives the mixing rack, causing the internal mixture to be mixed evenly.

[0039] While waiting for the mixing process, the electric heating ring heats and melts the mixture, improving the mixing effect;

[0040] The melted and mixed asphalt material is fed into an insulated guide hopper, where it is collected and discharged.

[0041] This invention recycles and reuses old asphalt mixtures, saving resources, avoiding the purchase costs of fresh asphalt mixtures, and reducing road construction and maintenance costs. Recycled and reused asphalt mixtures typically exhibit good performance in terms of strength, durability, and water resistance, providing better pavement performance.
