Description

Technical Field

[0001] The invention belongs to the technical field of dust removal and noise reduction devices, and in particular relates to a dust removal and noise reduction device for dismantling scrapped vehicles. Background Art

[0002] End-of-life vehicle dismantling is the professional processing of vehicles that have reached scrap standards. This process begins with pre-treatment of the vehicle, such as draining the oil and removing hazardous components like the battery. Subsequently, specialized equipment and techniques are used to dismantle major components, including the body, engine, and transmission. These dismantled parts are then sorted. Remanufactured parts are repaired and returned to the market, while non-reusable parts undergo environmentally friendly recycling, such as metal smelting and plastic recycling. Dismantling not only promotes resource recycling and reduces environmental pollution, but also promotes the green and sustainable development of the automotive industry, achieving a win-win situation for both economic and environmental benefits.

[0003] Conventional air filtration and separation devices are designed near scrapped vehicle dismantling sites to filter and purify dust. Existing air filtration and separation devices rely solely on filters to filter dust. However, due to the long-term operation of the filters and the inability to automatically replace them, large amounts of dust are generated continuously at scrapped vehicle dismantling sites. Dust accumulates over time, much like dust accumulates on a window screen after use, leading to clogging of the filter pores. This significantly reduces the efficiency of air flow through the filter, preventing it from effectively intercepting large amounts of dust and significantly reducing the filtration effectiveness. Furthermore, with dust accumulation and prolonged use, the filter material gradually ages and becomes brittle. Under the impact of air flow and dust particles, the filter is prone to damage and perforation. Once the filter is damaged, dust passes directly through the damaged area, completely losing its filtering function. This leads to a sharp deterioration in on-site air quality and poses a serious threat to worker health. To address these issues, a dust removal and noise reduction device for scrapped vehicle dismantling is highly desirable. Summary of the Invention

[0031] The preferred embodiment of the dust removal and noise reduction device for dismantling scrapped vehicles provided by the present invention is as follows: Figures 1 to 7 As shown:

[0032] A dust removal and noise reduction device for dismantling scrapped vehicles includes an air intake hood 1, a sound insulation component 2 is provided on the outside of the air intake hood 1, a plurality of air intake pipes 3 distributed in a circumferential array are connected and fixedly installed on the air intake hood 1, a guide sleeve 4 is connected and fixedly installed on the air intake pipe 3, a spline groove is provided in the guide sleeve 4, a movable tube 5 is inserted in the guide sleeve 4, a spline is provided on the outside of the movable tube 5, the movable tube 5 is slidably installed on the guide sleeve 4, and the movable tube 5 is spline-connected to the guide sleeve 4.

[0033] The ends of the movable tubes 5 are all connected and fixedly installed with air inlet nozzles 6, which are arranged in a trumpet shape. A spring 7 is arranged in the guide sleeve 4, one end of the spring 7 is fixedly connected to the guide sleeve 4, and the other end of the spring 7 is fixedly connected to the end of the movable tube 5. Multiple guide sleeves 4, movable tubes 5 and air inlet nozzles 6 are distributed in a circular array, and an adjustment mechanism is provided on the air intake hood 1, which is connected to multiple movable tubes 5, and the adjustment mechanism is used to adjust the positions of multiple air inlet nozzles 6. An outer shell 29 is provided at one end of the air intake hood 1, and an air chamber is provided inside the outer shell 29. One end of the air intake hood 1 can be rotatably mounted on the outer shell 29, and the air intake hood 1 is connected to the outer shell 29. A filtering mechanism is provided at the other port of the outer shell 29, and the filtering mechanism is used to filter the air discharged from the port of the outer shell 29.

[0034] The sound insulation component includes foam aluminum 201 and sound-absorbing cotton 202, which are pasted together. The air intake cover 1 passes through the assembly of foam aluminum 201 and sound-absorbing cotton 202, and the air intake cover 1 can be rotatably installed on the assembly of foam aluminum 201 and sound-absorbing cotton 202.

[0035] A sealing gasket is provided on the outer edge of the assembly of the foam aluminum 201 and the sound-absorbing cotton 202. The provision of the sealing gasket improves the sealing performance between the assembly of the foam aluminum 201 and the sound-absorbing cotton 202 and the ventilation port of the studio. A support seat 8 is fixedly mounted on the bottom of the outer shell 29. The filtering mechanism includes a connecting cover 19 connected to the other end of the outer shell 29 by screws. The connecting cover 19 is connected to the internal air chamber of the outer shell 29. The connecting cover 19 is provided with a plurality of air ports 20 distributed in a circular array. The air ports 20 are each provided with a filter screen 21, which is fixedly mounted on the connecting cover 19. A turntable 22 is rotatably mounted on the connecting cover 19. The turntable 22 is provided with an exhaust port 23. An air pump 24 is fixedly mounted on the turntable 22. The air inlet pipe of the air pump 24 is connected to the exhaust port 23. The exhaust pipe of the air pump 24 is connected to the outside world. A power supply 25 is fixedly mounted on the turntable 22. The power supply 25 supplies power to the air pump 24. A gear ring 26 is sleeved and fixedly mounted on the outer side of the turntable 22 , a stepper motor 27 is fixedly mounted on the support seat 8 , a driving wheel 28 is fixedly mounted on the output shaft end of the stepper motor 27 , and the driving wheel 28 is meshed with the gear ring 26 .

[0036] First, install the aluminum foam 201 and sound-absorbing foam 202 assembly at the workroom ventilation opening. The device draws in dust-laden air through multiple intake pipes 3, guide sleeves 4, movable pipes 5, and air inlet nozzles 6 arranged in a circular array on the air intake hood 1. The air inlet nozzles 6 are designed in a trumpet shape, which helps expand the air intake range and improve intake efficiency. The movable pipe 5 is spline-connected to the guide sleeve 4 and connected by a spring 7. An adjustment mechanism allows the positions of the multiple air inlet nozzles 6 to be adjusted to suit different working environments and air intake requirements.

[0037] Air enters through the air inlet nozzle 6, passes through the movable tube 5, the air inlet pipe 3, and then enters the air chamber inside the housing 29. When the dust-laden air is discharged from the port of the housing 29, it passes through the filter mechanism. The filter mechanism's connecting cover 19 communicates with the air chamber inside the housing 29. Connecting cover 19 has multiple air ports 20, each of which is equipped with a filter screen 21. As air passes through filter screen 21, dust is intercepted by filter screen 21, while relatively clean air passes through filter screen 21.

[0038] The stepper motor 27 starts, and the driving wheel 28 at the end of its output shaft drives the ring gear 26 to rotate, thereby rotating the turntable 22. An exhaust port 23 is provided on the turntable 22, and the air inlet pipe of the air pump 24 is connected to the exhaust port 23, and the exhaust pipe of the air pump 24 is connected to the outside world. As the turntable 22 rotates, the exhaust port 23 is aligned with different air ports 20 in turn. When the filter 21 in an air port 20 is clogged or damaged due to dust accumulation over a long period of operation, the turntable 22 rotates, causing the exhaust port 23 to switch to the next air port 20, and the new filter 21 is used to continue filtering, ensuring that the device can continuously and effectively filter the air, and avoiding a decrease in filtering effect due to problems with a single filter.

[0039] The noise reduction principle: A sound insulation assembly 2 is installed outside the air intake hood 1. This assembly consists of aluminum foam 201 and sound-absorbing cotton 202 glued together. The air intake hood 1 passes through this assembly and can be rotatably mounted on it. The porous structure of the aluminum foam 201 absorbs and reflects sound waves, providing a certain degree of sound insulation. The sound-absorbing cotton 202 further absorbs sound energy, reducing sound transmission. A sealing gasket is placed on the outer edge of the assembly to improve the seal with the workroom ventilation port, preventing sound leakage through the gap and enhancing the noise reduction effect.

[0040] By providing multiple air inlet nozzles 6 arranged in a circular array, the air intake range can be expanded and dust removal efficiency improved. An adjustment mechanism adjusts the position of the multiple air inlet nozzles 6, allowing them to draw air from different locations in the workshop, expanding the air intake range and further optimizing dust removal. The filtration mechanism includes multiple filters 21. The coordination of a turntable 22 and an air pump 24 enables automatic switching of the filters 21. Rotating the turntable 22 forces the different filters 21 into their operating positions. If a filter 21 becomes clogged due to dust accumulation, rotating the turntable 22 allows another clean filter 21 to enter its operating position, maintaining stable dust removal. Automatically switching filters 21 prevents excessive dust accumulation on a single filter 21 due to long-term operation, thereby extending the overall service life of the filter 21. Automatic filter switching also reduces the frequency of manual filter replacement, lowering maintenance costs. Through effective dust removal and noise reduction, this device can significantly improve air quality at scrapped vehicle dismantling sites and reduce the health risks posed by dust to workers. The operation of the device also helps to reduce noise pollution and improve the quality of the working environment.

[0041] In a further preferred embodiment of the present invention:

[0042] The adjustment mechanism includes a plurality of adjustment components distributed in a circular array. Each adjustment component is mounted on the air intake hood 1. The adjustment component includes two spaced apart support members 9, each of which is fixedly connected to the air intake hood 1. A rotating shaft 10 is rotatably mounted between the two support members 9. A reel 11 is fixedly mounted on each rotating shaft 10. A connecting block 12 is fixedly connected to each movable tube 5. A connecting rope 13 is fixedly connected to the connecting block 12. The other end of the connecting rope 13 is fixedly connected to the reel 11. Limiting plates 15 are fixedly mounted at both ends of the reel 11. Bevel gears 14 are fixedly mounted at both ends of the rotating shaft 10, and the two opposing bevel gears 14 are in a meshing state. A servo motor 16 is fixedly mounted on the air intake hood 1. A synchronous belt mechanism 17 is mounted on one of the rotating shafts 10 and on the output shaft of the servo motor 16. The servo motor 16 drives one of the rotating shafts 10 to rotate via the synchronous belt mechanism 17. A protective cover 18 is provided on one side of the air intake cover 1 . The protective cover 18 is fixedly mounted on the air intake cover 1 . The protective cover 18 is mounted outside the adjustment mechanism, the servo motor 16 and the synchronous belt mechanism 17 .

[0043] In this embodiment, when the position of the air inlet nozzle 6 needs to be adjusted, the servo motor 16 is activated, serving as the core power source, and begins outputting power. The output shaft of the servo motor 16 is connected to one of the rotating shafts 10 via a synchronous belt mechanism 17. With its smooth and precise power transmission characteristics, the synchronous belt mechanism 17 transmits the rotational power output by the servo motor 16 to the rotating shaft 10, causing it to rotate. The driven rotating shaft 10 is equipped with bevel gears 14 at both ends. Because the two opposing bevel gears 14 are meshed, when one bevel gear 14 rotates with the rotating shaft 10, it drives the other bevel gear 14 to rotate through the meshing relationship. Because the adjustment components are arranged in a circular array, the meshing transmission of the bevel gears 14 enables synchronized rotation of the rotating shafts 10 in each adjustment component. A reel 11 is fixedly mounted on each rotating shaft 10. As the rotating shaft 10 rotates synchronously, each reel 11 also rotates synchronously. A connecting block 12 is fixedly connected to the movable tube 5, which is connected to the reel 11 via a connecting rope 13. When the reel 11 rotates, it reels or releases the connecting rope 13. If the reel 11 reels the connecting rope 13, the connecting rope 13 pulls the connecting block 12, which in turn drives the movable tube 5 to slide along the guide sleeve 4, causing the air inlet nozzle 6 to move toward the air inlet hood 1. If the reel 11 releases the connecting rope 13, the spring 7, one end of which is fixed to the guide sleeve 4 and the other end is fixed to the end of the movable tube 5, causes the movable tube 5 to slide along the guide sleeve 4 away from the air inlet hood 1, causing the air inlet nozzle 6 to move outward, thereby adjusting the position of the air inlet nozzle 6.

[0044] The limit plates 15 provided at both ends of the reel 11 can limit the winding position of the connecting rope 13 on the reel 11, prevent the connecting rope 13 from falling off, and ensure the stability of the adjustment process. This is like setting a limit track for the tape of a tape measure to prevent the tape from deviating or falling off. A fixed protective cover 18 is provided on one side of the air intake hood 1, which wraps components such as the adjustment mechanism, servo motor 16 and synchronous belt mechanism 17. It can effectively prevent external dust and debris from entering the interior of the adjustment mechanism to avoid affecting its normal operation. At the same time, it can also play a safety protection role to prevent workers from contacting moving parts and causing danger.

[0045] Through this series of coordinated work, the regulating mechanism can achieve synchronous adjustment of the positions of multiple air inlet nozzles 6, can absorb air from different workshop locations, and improve the air intake range.
