[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of an asphalt processing dust removal mechanism, comprising a dust collection box 1, a fixed frame 2 fixedly connected inside the dust collection box 1, a collection box 3 slidably connected to the inner wall of the fixed frame 2, a fixed block 4 fixedly connected inside the fixed frame 2, a push rod 5 slidably connected inside the fixed block 4, a rotating shaft 6 fixedly connected inside the push rod 5, a sliding plate 7 slidably connected to the outer wall of the rotating shaft 6, the outer wall of the sliding plate 7 slidably connected inside the fixed block 4, a pull rod 8 fixedly connected to the outer wall of the sliding plate 7, the outer wall of the pull rod 8 slidably connected inside the fixed block 4, and a locking post 9 fixedly connected to the outer wall of the pull rod 8. The outer wall of the clamping post 9 is slidably connected to the inside of the collection box 3, and the outer wall of the clamping post 9 is slidably connected to the inside of the fixing block 4. One end of the spring 10 is fixedly connected to the outer wall of the clamping post 9, and the other end of the spring 10 is fixedly connected to the inside of the fixing block 4. A dust collection assembly is provided inside the dust collection box 1. The dust collection assembly is used to absorb dust and air. The dust collection assembly includes an air inlet pipe 11. The outer wall of the air inlet pipe 11 is fixedly connected to the inside of the dust collection box 1, and the outer wall of the air inlet pipe 11 is slidably connected to the inside of the collection box 3. A fan 12 is fixedly connected to the outer wall of the air inlet pipe 11, and the outer wall of the fan 12 is fixedly connected to the upper surface of the dust collection box 1.
[0025] Specifically, the fixing frame 2 is fixed inside the dust collection box 1 to support the collection box 3, which collects dust generated during asphalt processing. The fixing block 4 is fixed inside the fixing frame 2 to support the push rod 5. The push rod 5 pushes the slide plate 7 to slide through the rotating shaft 6. The slide plate 7 has a groove inside, which allows the rotating shaft 6 to slide and squeeze the slide plate 7. The pull rod 8 connects the slide plate 7 and the locking post 9, allowing the locking post 9 to slide out of the collection box 3. At this point, the collection box 3 can be removed from the fixing frame 2 to clean the dust collected inside. The spring 10, after being stretched, rebounds and locks the locking post 9 inside the collection box 3 for fixation. The dust collection box 1 fixes the fan 12, which adsorbs external dust. The air inlet pipe 11 transports dust and gas from the fan 12 to the collection box 3, where the collection box 3 filters the gas.
[0026] Reference Figure 2 and Figure 5A motor 13 is fixedly connected inside the dust collector 1. A drive shaft 14 is fixedly installed at the output end of the motor 13. A bracket 15 is rotatably connected to the outer wall of the drive shaft 14. The outer wall of the bracket 15 is fixedly connected to the inside of the dust collector 1. A limit frame 16 is fixedly connected to the outer wall of the bracket 15. A rotating block 17 is fixedly connected to the outer wall of the drive shaft 14. A fixed shaft 18 is fixedly connected inside the rotating block 17. A rotating disk 19 is rotatably connected to the outer wall of the fixed shaft 18. A spray head 22 is fixedly connected to the outer wall of the rotating disk 19. A connecting shaft 20 is rotatably connected inside the rotating disk 19. A ball bearing 21 is fixedly connected to the outer wall of the connecting shaft 20. The outer wall of the ball bearing 21 is slidably connected to the inner wall of the limit frame 16.
[0027] Specifically, the dust collection box 1 serves to fix the motor 13. Driven by the motor 13, the rotating block 17 rotates via the drive shaft 14. The bracket 15 is fixed inside the dust collection box 1 and supports the drive shaft 14. The limiting frame 16 is fixed to the outer wall of the bracket 15 and restricts the movement trajectory of the ball bearing 21. The fixed shaft 18 connects the rotating block 17 and the rotating disk 19, allowing the rotating disk 19 to drive the spray head 22 to rotate. The connecting shaft 20 connects the rotating disk 19 and the ball bearing 21. The connecting shaft 20 also rotates slightly inside due to the rotation of the rotating disk 19, causing the ball bearing 21 to slide inside the limiting frame 16 via the connecting shaft 20. The rotation of the rotating disk 19 allows the spray head 22 to spray the gas inside the dust collection box 1 evenly, improving the purification effect.
[0028] Reference Figure 4 and Figure 5 A liquid tank 23 is fixedly connected to the outer wall of the dust collection box 1. A water pump 24 is fixedly connected to the upper surface of the liquid tank 23. A hose 25 is fixedly connected to the output end of the water pump 24. The outer wall of the hose 25 is fixedly connected to the inside of the spray head 22. The outer wall of the hose 25 is slidably connected to the inside of the dust collection box 1.
[0029] Specifically, the liquid tank 23 serves to store the purification liquid, the water pump 24 serves to pump water, and the water pump 24 is used to extract the purification liquid inside the liquid tank 23. The hose 25 serves to transport the purification liquid from inside the liquid tank 23 to inside the spray head 22 for spraying. During the rotation of the spray head 22, the hose 25 will supply water stably and will not cause the water supply to be unstable due to rotation.
[0030] Reference Figure 1 An exhaust pipe 26 is fixedly connected inside the dust collector 1, and a sealing door 27 is slidably connected to the inner wall of the dust collector 1. A handle 28 is fixedly connected to the outer wall of the sealing door 27.
[0031] Specifically, the purified air can be discharged through the exhaust pipe 26 to avoid environmental pollution caused by direct discharge. The sealing door 27 serves to seal the inside of the dust collection box 1, and the handle 28 facilitates the opening of the sealing door 27.
[0032] Working principle: When this mechanism is needed, the fan 12 draws dust and exhaust gas generated during asphalt processing into the collection box 3 through the air inlet pipe 11 for collection. The collection box 3 is equipped with filter holes to allow gas to be discharged and dust to be collected. When the collection box 3 needs to be cleaned or replaced, pull the handle 28 to open the sealing door 27. Simply press the push rod 5, which will push the slide plate 7 through the internal rotating shaft 6. The sliding action of the slide plate 7 will cause the pull rod 8 to drive the locking pin 9 to slide, stretching the spring 10. Sliding the locking pin 9 out of the collection box 3 allows the collection box 3 to be removed from the inner wall of the fixing frame 2 for cleaning and replacement. This achieves the effect of collecting dust and facilitating the replacement of the collection box 3, saving maintenance time. Starting the motor 13 drives the drive shaft 14 to rotate. The rotation of the drive shaft 14 can... The rotating block 17 rotates, which drives the rotating disk 19 and the spray head 22 to rotate via the internal fixed shaft 18. During the rotation, the rotating disk 19 drives the ball bearing 21 to slide on the inner wall of the limit frame 16 via the connecting shaft 20. The spray head 22 also drives the hose 25 to slide. The water pump 24 is started to deliver the purification liquid through the hose 25 to the inside of the spray head 22 to purify the harmful gases inside the dust collection box 1. The rotation of the rotating disk 19 can spray the gas in multiple directions, thereby increasing the contact area with the harmful gases and improving the purification and dust removal efficiency, thus reducing environmental pollution. The purified gas is discharged through the exhaust pipe 26. This mechanism can not only quickly collect dust and facilitate the cleaning and replacement of the collection box 3, but also improve the purification and dust removal efficiency by spraying harmful gases in multiple directions.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
