[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1 - Figure 5 As shown, this utility model provides a waste asphalt recycling device, including a heating treatment box 1, a feeding pipe 3 installed on the top surface of the heating treatment box 1, a crushing roller 4 installed in the feeding pipe 3, an automatic return component 7 installed between the feeding pipe 3 and the top surface of the heating treatment box 1, and a screening screen 14 installed in the feeding pipe 3.

[0029] The inner cavity of the heat treatment box 1 is equipped with a stirring assembly 9, which is used to stir the asphalt in the inner cavity of the heat treatment box 1.

[0030] Furthermore, a control module 2 is installed on the outer wall of the heat treatment box 1. The control module 2 is connected to various electrical devices in the device through wires. When the device is in use, the operation of each device is controlled by the control module 2. The control module 2 can also control the timed start and operation of the electric push rod 702.

[0031] Furthermore, a discharge pipe 8 is provided on the bottom surface of the heat treatment box 1. The discharge pipe 8 connects the inner cavity of the heat treatment box 1 to the outside. A screening screen 10 is installed on the top surface of the inner cavity of the discharge pipe 8. The screening screen 10 is used to screen the asphalt discharged from the heat treatment box 1 to improve the recycling quality.

[0032] Furthermore, the heating treatment box 1, which realizes the heating function and structure, the stirring component 9, which realizes the stirring function, and the crushing roller 4, which realizes the structure and function, are the same as those provided in the existing utility model patent for a waste asphalt recycling device (publication number: CN220864497U), and will not be described in detail here.

[0033] A through groove 1 5 is provided above one side of the feed pipe 3, and a through groove 2 16 is provided below the side of the feed pipe 3 where the through groove 1 5 is provided.

[0034] Among them, a vibrating motor (not shown in the diagram) can be optionally installed on the side wall of the feed pipe 3 to improve the screening efficiency of the screening screen 14.

[0035] The automatic return assembly 7 includes a collection box 701 and two electric push rods 702;

[0036] Electric push rods 702 are symmetrically installed on the top surface of the heat treatment box 1. The telescopic ends of the two electric push rods 702 are jointly installed with a collection frame 701. A guide block 703 is installed on the bottom surface of the inner cavity of the collection frame 701.

[0037] A sealing plate 704 is installed on the bottom surface of the outer wall of the collection frame 701, and the side wall of the sealing plate 704 is in contact with the outer wall of the feed pipe 3.

[0038] In this embodiment, during the use of the device, the crushing roller 4 crushes the asphalt, and the crushed asphalt falls onto the top surface of the screening screen 14. At this time, asphalt fragments of suitable size will pass through the screening screen 14 and enter the inner cavity of the heat treatment box 1 for heating and stirring.

[0039] When the asphalt particles cannot pass through the second screening screen 14, the asphalt debris will slide along the second screening screen 14 to the outer wall between the guide block 703 and the feed pipe 3. The control module 2 controls the lifting frequency of the electric push rod 702 to lift the collection frame 701 and the closing plate 704 at regular intervals. At the same time as lifting, the closing plate 704 will close the second channel 16. As the collection frame 701 continues to rise, the collection frame 701 connects with the first channel 5. Under the guidance of the guide block 703, the large particles of asphalt debris inside the collection frame 701 will be poured into the feed pipe 3 through the first channel 5.

[0040] Subsequently, the electric push rod 702 will retract again, aligning the collection frame 701 with the through groove 16. The control module 2 controls the automatic return assembly 7 to repeat the above operation, realizing the benefit of automatically conveying the asphalt that does not meet the size requirements to the top of the crushing roller 4 and re-feeding it for crushing.

[0041] In a further embodiment, refer to Figure 1 - Figure 5 The outer wall of the feed pipe 3 is symmetrical to the side wall of the through groove 16, and an installation groove 11 is provided. The bottom surface of the inner cavity of the installation groove 11 is provided with a groove 12. An installation plate 13 is installed on the side wall of the installation groove 11 in the inner cavity of the feed pipe 3. The top surface of the installation plate 13 is at the same horizontal height as the bottom surface of the inner cavity of the installation groove 11.

[0042] A positioning component 18 is provided between the mounting slot 11 and the groove 12. The positioning component 18 includes a positioning frame 1801. Insertion blocks 1802 are symmetrically installed on the lower side wall of the positioning frame 1801. Multiple springs 1804 are evenly distributed on the top surface of the inner cavity of the positioning frame 1801. A sliding plate 1805 is installed at the bottom of the multiple springs 1804.

[0043] A sliding groove 1803 is provided on the outer wall of the positioning frame 1801 that is symmetrical to the side where the plug block 1802 is installed. A sliding block 1806 is installed on the upper side wall of the sliding plate 1805. The sliding block 1806 is slidably installed in the sliding groove 1803.

[0044] The sliding plate 1805 is slidably installed in the groove 12, and the top and bottom surfaces of the inner cavity of the mounting groove 11 respectively contact the top and bottom surfaces of the positioning frame 1801.

[0045] A snap-fit ​​frame 15 is symmetrically installed on the side wall of the screening mesh 14. A plug-in block 1802 is slidably installed on the snap-fit ​​frame 15. An abutment plate 17 is installed on the bottom surface of the inner cavity of the through groove 16.

[0046] The bottom surface of the outer wall of the snap-fit ​​frame 15 contacts the top surface of the mounting plate 13, and the side wall of the screening screen 14 contacts the abutment plate 17.

[0047] In this embodiment, when the device is in use, the screening screen 14 is subjected to the impact of asphalt debris for a long time, which causes damage. First, the sliding block 1806 is pulled, which drives the sliding plate 1805 to move upward, so that the sliding plate 1805 moves out of the groove 12 and the spring 1804 is compressed and then retracts into the positioning frame 1801.

[0048] Further, the positioning frame 1801 is removed from the mounting slot 11. At this time, the plug block 1802 on the positioning frame 1801 will slide out from the snap-fit ​​frame 15, releasing the restriction on the snap-fit ​​frame 15 and the screening screen 14 on which the snap-fit ​​frame 15 is installed. Then, the screening screen 14 is removed from between the mounting plate 13 and the contact plate 17 and a new screening screen 14 is replaced.

[0049] When installing the new screening screen 14, the side wall of the screening screen 14 should be in contact with the contact plate 17, and the bottom surface of the snap-fit ​​frame 15 should be overlapped with the top surface of the mounting plate 13.

[0050] Further pulling the sliding block 1806 causes the sliding plate 1805 to retract into the inner cavity of the positioning frame 1801, and the positioning frame 1801 is aligned with the mounting groove 11 and inserted. As the positioning frame 1801 is inserted, the insertion block 1802 on the positioning frame 1801 will be inserted into the snap-fit ​​frame 15, thereby positioning the snap-fit ​​frame 15 and the screening screen 14 on which the snap-fit ​​frame 15 is installed. Finally, the force on the sliding block 1806 is released, and under the action of the spring 1804, the sliding plate 1805 will be inserted into the groove 12 to achieve overall positioning of the positioning assembly 18. This provides the benefit of quick replacement of the screening screen 14, which is easily damaged by long-term impact, and improves the practicality of the device.
