Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example

[0027] See also Figures 1 to 8 , is an embodiment of the present invention, which provides a technical solution: an asphalt hot regeneration device for preventing sticking, comprising

[0028] A tank body 1, a stirring motor 4 installed on the top of the tank body 1, two feeding ports 2 arranged on the top of the tank body 1 and communicating with the inside of the tank body 1, a stirring paddle is rotatably arranged inside the tank body 1, the bottom end of the central axis of the stirring paddle is rotatably connected to the inner wall of the tank body 1 through a bearing, and the output end of the stirring motor 4 is connected to the top end of the central axis of the stirring paddle, so that the subsequent stirring motor 4 can drive the central axis to rotate, the model of the stirring motor 4 is D-8401WZ-50W, and the subsequent stirring motor 4 can drive the stirring paddle inside the tank body 1 to rotate after being started, so as to realize continuous mixing and stirring of the asphalt inside the tank body 1, and at the same time, a heating plate is also arranged at the bottom end of the inner side of the tank body 1, and the specific model of the heating plate is INSTEC HCC206R / RF, which can heat the material in the tank body 1, so that the asphalt can be continuously hot-stirred after entering the tank body 1 through the feeding port 2, and the above structural principles are all technologies that have been disclosed in the prior art, and the specific details can be referred to the existing patent with the publication number CN205954448U, which will not be elaborated here;

[0029] And an anti-sticking scraping mechanism 5 arranged on the feed port 2, including an anti-sticking scraping frame 55 attached to the inner wall of the feed port 2, and two driving cylinders 51 fixed to the surfaces of both sides of the feed port 2 by bolts. The specific model of the driving cylinder 51 is ADVC-63-20-AP, and a movable side seat 52 is connected to the piston rod at the bottom end of the driving cylinder 51. The movable side seat 52 is slidably located on the side of the feed port 2. A connecting block 57 is welded and fixed to one side of the movable side seat 52. Strip slideways 54 corresponding to the connecting block 57 are provided on both side surfaces of the feed port 2. The connecting block 57 is slidably located in the strip slideway 54, and the inner end of the connecting block 57 is connected to the anti-sticking scraping frame 55. The anti-sticking scraping mechanism 5 also includes a disassembly and assembly structure 53, so that after the subsequent driving cylinder 51 is started, the movable side seat 52 can be driven to lift and lower the anti-sticking scraping frame 55. The cross-section of the anti-sticking scraping frame 55 is a right triangle, and the tip of the right triangle faces upward. Therefore, when the anti-sticking scraping frame 55 rises, its top end will effectively scrape off the sticky asphalt on the lower inner wall of the feed port 2, and the scraped asphalt will fall into the interior of the tank body 1, so as to prevent the lower inner wall of the feed port 2 from being excessively sticky with more asphalt and causing unnecessary blockage, thereby ensuring the long-term stable operation of the equipment and solving the problem that the feed port of the original asphalt hot regeneration equipment is easily sticky with more asphalt and causes unnecessary blockage.

[0030] Among them, a connecting head 571 is welded and fixed at the inner end of the connecting block 57, and two connecting grooves 551 corresponding to the connecting head 571 are arranged on the side of the anti-sticking scraping frame 55, and the bottom end of the connecting groove 551 is communicated with the bottom surface of the anti-sticking scraping frame 55, so that the connecting head 571 can slide into the connecting groove 551 from the bottom of the anti-sticking scraping frame 55 during the early assembly, and then the assembly and connection can be carried out with the help of the disassembly structure 53. The disassembly structure 53 includes an L-shaped plate 531 movably installed on the bottom surface of the movable side seat 52, and the top of the L-shaped plate 531 extends upward to the side surface of the movable side seat 52, and a limiting rod 534 is welded and fixed to the inner side of the L-shaped plate 531, and the inner wall of the connecting groove 551 is provided with a limiting rod 534. The limit rod 534 passes horizontally through the movable side seat 52, the connecting block 57 and the connecting head 571, and is inserted into the limit groove 536, so as to realize the smooth connection between the anti-sticking scraper frame 55 and the connecting block 57. The surfaces of the movable side seat 52, the connecting block 57 and the connecting head 571 are all provided with a horizontal through-hole for the smooth penetration of the limit rod 534. The disassembly and assembly structure 53 also includes a bottom slide groove 532 provided on the bottom surface of the movable side seat 52, and a bottom slider 533 and a spring 535 are provided in the bottom slide groove 532. The bottom slider 533 is movably installed in the bottom slide groove 532 by the spring 535, and the bottom end of the bottom slider 533 extends to the bottom surface of the movable side seat 52. The end of the limiting rod 534 can be stably inserted into the limiting groove 536 under the push of the spring 535 during daily use, thereby ensuring the connection stability between the anti-sticking scraper frame 55 and the connecting block 57, and ensuring that it can be smoothly driven by the driving cylinder 51 to lift and lower in the future. When the anti-sticking scraper frame 55 needs to be removed for inspection, maintenance or cleaning, it is only necessary to pull the L-shaped plate 531 sideways to move the bottom slider 533 sideways and compress the spring 535, causing the limiting rod 534 to move sideways until the end of the limiting rod 534 moves out of the limiting groove 536, so that the anti-sticking scraper frame 55 is no longer limited. At this time, the anti-sticking scraper frame 55 can be moved up and separated from the two connecting heads 571. The anti-sticking scraper frame 55 can be smoothly removed from the feed port 2 for maintenance to ensure the convenience of subsequent maintenance. When installing the anti-sticking scraper frame 55, first push the anti-sticking scraper frame 55 into the inside from the top of the feed port 2, and then pull the L-shaped plate 531 to the side again to make the end of the limiting rod 534 shrink into the connecting block 57. At this time, the anti-sticking scraper frame 55 can be moved down so that the connecting head 571 can smoothly enter the connecting groove 551. Finally, the L-shaped plate 531 is released so that the spring 535 pushes the bottom slider 533 back to reset, and finally the end of the limiting rod 534 is stuck in the limiting groove 536, so that the anti-sticking scraper frame 55 can be connected with the connecting head 571, and the anti-sticking scraper frame 55 can be quickly installed.

[0031] Among them, a cylindrical groove is opened on the side of the bottom sliding block 533, and one end of the spring 535 is inserted into the cylindrical groove to limit the spring 535 and prevent the spring 535 from deflecting. The other end of the spring 535 is fixed to the inner wall of the bottom sliding groove 532 to ensure the installation stability of the spring 535.

[0032] Among them, two side panels 56 are symmetrically welded and fixed on the top surface of the anti-sticking scraper frame 55, and the side panels 56 cover the strip slide 54, so that the asphalt material on the inner side of the feed port 2 will not leak out from the strip slide 54. The top of the side panel 56 is provided with an inclined surface 561, so that when the side panel 56 rises with the anti-sticking scraper frame 55, its top end can also scrape and clean the upper inner wall of the feed port 2 to a certain extent.

[0033] The bottom surface of the tank body 1 is provided with a discharge port 3, and the discharge port 3 is communicated with the interior of the tank body 1 for subsequent discharge.

[0034] Although embodiments of the present invention have been shown and described (see the above detailed description for details), it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
