Description

Technical Field

[0001] This utility model relates to the field of asphalt production technology, specifically to a multifunctional modified asphalt anti-clogging production device. Background Technology

[0002] Rubber-modified asphalt uses asphalt binder as a raw material, followed by the addition of modifiers in a specific ratio. This blending process relies on shearing and mixing techniques to ensure that the modifiers and asphalt binder are fully combined. However, current practice involves adding all powdered materials such as modifiers, fillers, and fibers to the asphalt binder at once, followed by mixing. This often results in uneven dispersion of the modifiers, causing some asphalt binder to fail to meet the intended quality standards.

[0003] In addition, the design of the raw material inlet of the existing production equipment also has certain limitations. When processing a large amount of raw materials, the inlet is prone to blockage due to material accumulation. This usually requires manual unblocking, which is not only time-consuming and labor-intensive, but also greatly reduces the overall work efficiency. At the same time, the flue gas emitted by the existing production equipment during the production process will also cause environmental pollution. Utility Model Content

[0018] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, this utility model will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it. The technical solution of this utility model will be described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0019] See Figures 1 to 5 This embodiment proposes a multifunctional modified asphalt anti-clogging production device, including a production tank 1, a feeding cylinder 2, a stirring shaft 5, a main impeller 6, a four-bladed agitator 7, a drive motor 8, a temperature controller 9, a flue gas purification device 10, a support rod 13, a roller 15, and a control switch 17.

[0020] A feeding cylinder 2 is connected to one side of the top of the production barrel 1, and a flue gas purification device 10 is connected to the other side of the top of the production barrel 1. A drive motor 8 is fixed at the center of the top of the production barrel 1, and a stirring shaft 5 is connected to the drive end of the drive motor 8. The stirring shaft 5 extends into the interior of the production barrel 1 and is rotatably connected to the production barrel 1. A main impeller 6 is connected to the bottom of the stirring shaft 5, and a four-bladed stirring paddle 7 is connected to the middle of the stirring shaft 5. The main impeller 6 and the four-bladed stirring paddle 7 are both vertically distributed on the stirring shaft 5. By rotating the stirring shaft 5, the main impeller 6 and the four-bladed stirring paddle 7 are driven to rotate, and the raw materials at the bottom and top of the production barrel 1 are fully mixed and stirred under the coordinated action of the main impeller 6 and the four-bladed stirring paddle 7.

[0021] The upper end of the feeding cylinder 2 is provided with a bowl-shaped inlet 3, and the bottom end of the feeding cylinder 2 is provided with a discharge outlet. The feeding device 4 is installed inside the feeding cylinder 2. The feeding device 4 includes a mounting box 401, a small motor 402, a connecting rod 403, a feeding shaft 404, a propeller blade 405, a bracket 406, and a feeding blade 407. The mounting box 401 is installed on both sides of the upper end of the feeding cylinder 2 through the connecting rod 403, and the small motor 402 is located inside the mounting box 401. The top of the mounting box 401 is a conical structure; the bottom drive end of the small motor 402 is connected to the feeding shaft 404, which extends from the upper part of the feeding cylinder 2 to the lower part of the feeding cylinder 2. On the outer wall of the feeding shaft 404 and along the length direction of the feeding shaft 404, there are propeller blades 405 and feeding blades 407 arranged sequentially from top to bottom. The diameters of the propeller blades 405 and feeding blades 407 gradually decrease from top to bottom along the length direction of the feeding shaft 404.

[0022] The feeding cylinder 2 is equipped with a support 406, which strengthens the feeding cylinder 2. The feeding shaft 404 passes through the support 406 via a bearing. A small motor 402 drives the feeding shaft 404 to rotate, which in turn causes the propeller blade 405 and the feeding blade 407 to rotate, promoting feeding and preventing blockage at the feed inlet 3 due to material accumulation.

[0023] Temperature controllers 9 are installed on both sides of the production drum 1. Each temperature controller 9 contains a heating device, a cooling device, and a thermometer, and an external control switch 17. By heating or cooling the production drum 1 according to the production requirements, the temperature controllers 9 can ensure that the produced modified asphalt is uniform and of stable quality. A fixed cylinder 11 is welded to the discharge port at the bottom of the production drum 1. A discharge cylinder 16 is sleeved on the outside of the fixed cylinder 11. The discharge cylinder 16 can slide relative to the fixed cylinder 11 to adjust the height of the discharge port. The discharge cylinder 16 and the fixed cylinder 11 are fixedly connected by bolts. The discharge cylinder 16 is equipped with a control valve.

[0024] The flue gas purification device 10 includes an inlet cylinder 1001, a purification tank 1002, a support pipe 1003, an exhaust pipe 1004, and a sponge block 1005. The production tank 1 is connected to the purification tank 1002 through the inlet cylinder 1001. The purification tank 1002 is connected to the exhaust pipe 1004 through the support pipe 1003. An exhaust fan is installed at the connection between the purification tank 1002 and the support pipe 1003. A sponge block 1005 is installed at the outlet of the exhaust pipe 1004. The flue gas generated during the production process enters the purification tank 1002 through the inlet cylinder 1001. The gas filtered by the purification tank 1002 enters the exhaust pipe 1004 through the support pipe 1003 via the exhaust fan, and is then discharged into the atmosphere after secondary filtration by the sponge block 1005.

[0025] The production barrel 1 has retractable support rods 13 connected to the four corners of its bottom. The bottom of the support rods 13 is connected to rollers 15 with a self-locking function. The support rods 13 include a fixed rod and a threaded rod 14. The threaded rod 14 extends from the bottom of the fixed rod and is sleeved inside the fixed rod. The fixed rod and the threaded rod 14 are connected and fixed by a limiting bolt 12. The rollers 15 are connected to the bottom of the threaded rod 14. The height of the production barrel 1 can be adjusted by the support rods 13 to suit different production environments. The rollers 15 facilitate the overall movement of the production barrel 1.

[0026] The usage process of the multifunctional modified asphalt anti-clogging production device described in this embodiment is as follows: Connect the power supply to the electrical components, turn on the feeding device 4, place the raw material in the feed inlet 3, and drive the feeding shaft 404 to rotate through the small motor 402 in the feeding device 4. The raw material is fed through the action of the propeller blade 405 and the feeding blade 407. The raw material enters the production barrel 1 from the discharge port of the feeding cylinder 2. Then, the drive motor 8 drives the stirring shaft 5 to rotate to produce modified asphalt. Under the combined action of the main impeller 6 of the stirring shaft 5 and the four oblique blade stirring blades 7, longitudinal and transverse mixing is achieved. This design allows for better circulation of the raw materials within production tank 1, effectively preventing the formation of unidirectional eddies and generating multidirectional tumbling flows. This significantly enhances the mixing effect of the agitator, resulting in a more uniform solid-liquid distribution, thereby improving the reaction rate and mixing effect, and promoting better fusion. During rotation, the temperature controller 9 is activated to heat production tank 1, ensuring uniform mixing of the raw materials and preventing stratification. The fumes generated during production enter the purification tank 1002 through the air inlet 1001. The exhaust fan inside the purification tank 1002 blows the fumes to the exhaust pipe 1004, where the purified fumes are discharged into the atmosphere. After the modified asphalt production is complete, the temperature controller 9 is used to cool production tank 1, preventing the produced modified asphalt from becoming unstable due to excessive temperature. Finally, the produced modified asphalt is discharged through the discharge pipe 16 of production tank 1. During use, adjustments or movement of production tank 1 can be made by adjusting the support rod 13 or the rollers 15.
