[0001] This invention relates to the field of end-of-life vehicle processing, and more specifically to a device for processing end-of-life vehicle waste. Background Technology

[0002] The disposal of scrapped vehicles mainly focuses on the processing of metal parts. However, the interior and other non-metallic components of vehicles often use a large number of ABS plating parts with metal coatings, such as interior trim pieces. The recycling of these ABS plating parts is often overlooked, leading to the waste of some metal materials. Although existing technologies exist for recycling plating parts, most of them use one-step processing, resulting in low recycling efficiency, and there is a lack of highly efficient integrated recycling equipment.

Specifically, the second mesh bag is tilted, and the material in the second mesh bag falls into the third material cylinder. Simultaneously, the gear on the rotating shaft rotates, driving the rack upwards. In this way, after soaking is complete, both the solid phase material is poured out and the remaining liquid phase is discharged. Attached Figure Description

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] In some embodiments of the present invention, a waste treatment device for scrapped vehicles is disclosed, comprising: an immersion mechanism including a first cylinder 2 and a second cylinder 3 for cleaning metal and ABS plated parts respectively, and a third cylinder 13 for removing the ABS plated parts. The first cylinder 2 and the second cylinder 3 are respectively provided with a first mesh bag 11 and a second mesh bag 12 for containing solid phases. A waste liquid collection area disposed below the immersion mechanism includes a first container 5 for collecting the liquid phase discharged from the first cylinder 2 and the second cylinder 3, and a second container 6 for collecting the liquid phase discharged from the third cylinder 13. A drying mechanism including a first roller 7 and a second roller 9 for receiving the cleaned metal and the ABS plated parts respectively, and a heating channel 15 surrounding the first roller 7 and the second roller 9. A pyrolysis furnace 8 for receiving the dried ABS plated parts, separating the ABS plated parts through pyrolysis, retaining and collecting the metal plating layer thereon, and the exhaust gas from the pyrolysis furnace 8 is output to the heating channel 15.

[0049] The aforementioned device can operate according to the following steps. In the initial state, it can perform preliminary mechanical dismantling of the scrapped vehicle. This process can be carried out manually or by hand. The specific process can be referred to conventional techniques in the field, and will not be described in detail in this application.

[0050] After collecting the raw materials, the scrap metal parts can be placed in the mesh bag 11 of material cylinder 2, and the ABS coated parts or other plastic parts with metal coatings can be placed in the mesh bag 12 of material cylinder 3 for soaking and cleaning. The metal coating typically includes chromium, nickel, etc., and is usually used to enhance the gloss or extend the lifespan of interior parts. The main cleaning targets include oil stains accumulated over long-term use.

[0051] After soaking, the metal parts can be retrieved by rotating the mesh bag 11. After the mesh bag 11 is flipped 180 degrees, the metal parts can be poured into the drum 7 for the next drying process. For ABS plated parts, after cleaning, a further soaking is required. Similarly, the mesh bag 22 is flipped by rotating the shaft 21. The ABS plated parts are then poured into the material cylinder 33. Unlike material cylinder 23, material cylinder 33 can contain a plating remover, which is not for removing oil stains, but for removing the metal plating layer on the ABS parts. The plating removal process is also a soaking process, using acid to remove the metal ions from the ABS and into the liquid phase. The acid can be hydrochloric acid, at which point the chromium and nickel metal plating can be converted into chromium chloride and nickel chloride. Alternatively, some complexing agents or powdered plating removers can be used, such as oxalic acid, sodium bisulfate, sodium citrate, etc. The remaining solid phase is mainly ABS or other plastic parts that are insoluble in acid.

[0052] At this point, the solid phase can be retrieved or filtered out, thus completing the initial deplating process. The remaining liquid phase enters container 2 (6), where an alkali, such as sodium hydroxide, can be added to precipitate the chromium and nickel ions. After retrieving or filtering the precipitate, the initial separation of the metal components is completed.

[0053] At this point, the remaining solid phase in the third cylinder 13 can enter the second drum 9 for drying.

[0054] Due to oxidation and other reasons in the metal layer of ABS plating, conventional immersion stripping may still not be sufficient to fully extract the metal. In order to further increase the extraction efficiency, in some embodiments of this application, after the drying treatment of the second drum 9, the solid phase after drying of the second drum 9 is subjected to pyrolysis or pyrolysis.

[0055] Specifically, the solid phase can be fed into a pyrolysis furnace 8, where the temperature can be set to 300°C to 600°C. Within this temperature range, ABS coated parts and other plastic parts can be sufficiently vaporized. A protective gas needs to be added to prevent undesirable reactions, such as metal oxidation. After pyrolysis is complete, the remaining powdered solid phase contains the remaining metal components, thus completing the separation of the metal components from the ABS.

[0056] It should be noted that drying is also a necessary step in the process of this application, and the waste gas output from pyrolysis can be utilized in the drying process. Specifically, the pyrolysis furnace 8 is connected to the heating channel 15 through the exhaust pipe 25. Since the heating channel 15 surrounds the outer wall of the first roller 7 and the second roller 9, and the temperature in the pyrolysis furnace 8 is higher than 100 degrees Celsius, even if cooling occurs during the process through the exhaust pipe 25, the temperature of the first roller 7 and the second roller 9 can be easily increased through heat conduction to achieve the drying effect. Of course, it should be noted that the gases from the high-temperature decomposition of ABS and other plastic parts often require further treatment, which means that the heating channel 15 cannot be directly connected to the first roller 7 and the second roller 9, or connected to the external environment, but requires further waste gas treatment, which can be existing waste gas treatment or the subsequent spraying mechanism of this application.

[0057] Preferred embodiments of the present invention will be further disclosed below to further optimize the function of the device of this application.

[0058] In a preferred embodiment of the present invention, the first material cylinder 2, the second material cylinder 3, and the third material cylinder 13 are arranged side by side in sequence, and the first mesh bag 11 is rotatably connected to the upper end face of the first material cylinder 2. A rotating shaft 21 is rotatably connected to the junction of the second material cylinder 3 and the third material cylinder 13. The rotating shaft 21 is fixedly connected to the second mesh bag 12, and a gear 28 is coaxially fixedly mounted on the rotating shaft 21. A connecting rod 30 is slidably connected to the inner wall of the second material cylinder 3, and a vertically arranged rack 29 is fixedly mounted on the connecting rod 30, the rack 29 meshing with the gear 28. A sealing element is fixedly mounted at the lower end of the connecting rod 30 to seal the drain outlet on the bottom surface of the second material cylinder 3. The second material cylinder 3 can be connected to the first container 5 through the drain outlet.

[0059] After soaking, the material in the second cylinder 3 needs to be transferred. This can be done manually or by driving the rotating shaft 21 with a motor or cylinder, causing the net bag 12 to tilt and the material to fall into the third cylinder 13. Simultaneously, the gear 28 on the rotating shaft 21 rotates, driving the rack 29 upwards. At the same time, the connecting rod 30 also moves upwards, causing the seal that was originally sealing the drain outlet to move upwards. Thus, after soaking, both the solid phase material is poured out, and the remaining liquid phase is discharged through the drain outlet into the first container 5. Conversely, when the rotating shaft 21 rotates in the opposite direction, the net bag 12 resets, ready to receive the next batch of ABS plating parts. Similarly, the seal at the waste liquid discharge outlet of the second cylinder 3 after cleaning and soaking re-closes the drain outlet, at which point new cleaning solution can be added.

[0060] In other embodiments of the present invention, the above-described cylinder layout and the flipping action of the second mesh bag 12 are also applied. Specifically, a hopper 4 for receiving and supplying the stripping agent to the third cylinder 13 is provided above the third cylinder 13. A discharge roller is provided at the outlet of the hopper 4. The first cylinder 2, the second cylinder 3, and the third cylinder 13 are arranged side by side in sequence, and the first mesh bag 11 is rotatably connected to the upper end face of the first cylinder 2. A rotating shaft 21 is rotatably connected at the junction of the material cylinder 2 3 and the material cylinder 3 13. The rotating shaft 21 is fixedly connected to the net bag 2 12. A pawl 41 is coaxially fixedly installed at one end of the rotating shaft 21. A turntable 31 is rotatably connected to the outer wall of the material cylinder 2 3. The inner wall of the turntable 31 has ratchet teeth 40. The pawl 41 can mesh with the ratchet teeth 40 to form a ratchet mechanism. A pulley 33 is coaxially fixedly installed on the turntable 31. A pulley 34 is rotatably connected to the outer wall of the hopper 4. The pulley 34 is coaxially fixedly connected to the feeding roller shaft. The pulley 33 and the pulley 34 are connected by a transmission belt 32.

[0061] Similar to the above embodiment, after the second barrel 3 is soaked, the rotation of the first shaft 21 in this embodiment also drives the second net bag 12 to rotate and tilt. Simultaneously with the rotation of the first shaft 21, the pawl 41 pushes the ratchet 40 on the turntable 31 to rotate, thereby driving the turntable 31 to rotate. The first pulley 33 on the turntable 31 rotates, driving the second pulley 34 and its discharge roller shaft to rotate, so that the powdered plating remover stored in the hopper 4 is output into the second barrel 3.

[0062] That is, since the rotating shaft 21 and the turntable 31 form a ratchet mechanism, when the rotating shaft 21 is tilted, it drives the discharge roller shaft to rotate, carrying the powdered plating remover out of the discharge bin 4.

[0063] At this point, it is necessary to pay attention to the angle and position of the flipped mesh bag 12 to avoid interfering with the output of the plating remover.

[0064] In a preferred embodiment of the present invention, a sealing plate 16 is provided between the material cylinder 13 and the container 6, the sealing plate 16 being used to close the opening on the bottom surface of the material cylinder 13. Symmetrical and horizontally arranged slide rails 26 are provided on both sides of the opening of the material cylinder 13, one end of which is connected to an arc-shaped slide rail 27. The container 6 is provided with a waste liquid inlet and an ABS plating inlet, and the slide rail 27 extends downward above the ABS plating inlet. One end of the sealing plate 16 can be selectively slidably connected to the slide rails 26 and 27. The other end of the sealing plate 16 is movably connected to the slide rail 26. A filter screen 17 is embedded in the sealing plate 16.

[0065] Although the sealing plate 16 is a sliding connection, in the initial state, the filter screen 17 on the sealing plate 16 is not within the opening range, that is, the opening is closed. The solid part of the sealing plate 16 is tightly attached to the joint of the opening, maintaining a tight sliding connection. After the stripping is completed, the metal enters the liquid phase in ionic form. At this time, it is desirable to initially separate the solid phase from the liquid phase. Then, the sealing plate 16 is slid horizontally so that the part of the filter screen 17 on the sealing plate 16 coincides with the opening of the material cylinder 13 in the vertical direction. At this time, the liquid phase can enter the inlet of the container 6 through the filter screen 17. In this state, both ends of the sealing plate 16 are still on the slide rail 26, and the sealing plate 16 is still in contact with the opening. Only the filter screen 17 enters the opening, allowing the liquid phase to be discharged, while the solid phase is still deposited on the filter screen 17 and the sealing plate 16.

[0066] At this point, the sealing plate 16 is pushed further, and one end of the sealing plate 16 moves to the end of slide rail 26, that is, the junction of slide rail 26 and slide rail 27. At this time, the end of the sealing plate 16 slides downward along slide rail 27 under the action of gravity. In this way, the end located on slide rail 27 begins to move away from the opening, causing the solid phase deposited on the sealing plate 16 to also fall out of the feed cylinder 13 and tilt downward into the lower roller 9.

[0067] In a preferred embodiment of the present invention, a spraying mechanism for treating the waste gas generated by the pyrolysis furnace 8 is also included. The spraying mechanism includes a housing 10, a filter layer 23, a rotating arm 24 with a plurality of nozzles, a second rotating shaft 22, an air inlet, and an air outlet. The second rotating shaft 22 is arranged vertically and is rotatably connected to the housing 10, and the rotating arm 24 is fixedly mounted on the second rotating shaft 22.

[0068] The air inlet is connected to the gas outlet of the heating channel 15.

[0069] In a preferred embodiment of the present invention, a frame 1 is further included, on which a first sprocket 19 and a pair of second sprockets 18 are rotatably connected. The pair of second sprockets 18 are respectively disposed below the first roller 7 and the second roller 9. The first sprocket 19 is disposed below the outer casing 10, and the second rotating shaft 22 is coaxially and fixedly connected to the first sprocket 19.

[0070] Both the first drum 7 and the second drum 9 are equipped with stirring blades, which are fixedly connected to the second sprocket 18. The first sprocket 19 and the pair of second sprockets 18 are connected by a transmission chain 20.

[0071] In this embodiment, due to the meshing of sprocket 19 and sprocket 18, when the stirring blades of drum 7 rotate, the stirring blades of drum 9 and shaft 22 also rotate synchronously. Specifically, the power source for the drive can be located on sprocket 19 or on shaft 21, and those skilled in the art can adjust it according to their needs.

[0072] In other words, during drying, the rotating agitator blades can stir the materials inside drum 7 and drum 9, accelerating the drying process. Simultaneously, it can also drive the rotating shaft 22 to rotate, which in turn drives the rotating arm 24 to rotate continuously, thereby achieving rotary spraying and improving the working efficiency of the spraying mechanism.

[0073] In a preferred embodiment of the present invention, a sorting mechanism is provided below the outer shell 10, including a cylinder 39, a magnetic separator 42 and an arc-shaped magnetic pole 43. The two ends of the magnetic separator 42 are coaxially fixedly mounted with a rotating shaft 38, which is rotatably connected to the cylinder 39. A worm gear 37 is coaxially fixedly mounted on the rotating shaft 38, and a worm 36 is coaxially fixedly mounted on the lower end of the rotating shaft 22. The worm gear 37 meshes with the worm 36.

[0074] Thus, when the second rotating shaft 22 rotates, in addition to driving the rotating arm 24 to rotate and perform spraying, it can also drive the worm gear 37 through the worm 36, thereby driving the third rotating shaft 38 and the magnetic separator 42 on it to rotate. At this time, dried precipitate or the solid phase remaining after pyrolysis in the pyrolysis furnace 8 is added to the feed inlet of the cylinder 39, which at the same time causes the magnetic pole 43 to generate a magnetic field, which will adsorb the nickel component, while the other components will fall into one of the discharge ports below. When the part of the magnetic separator 42 that has adsorbed the nickel component rotates until it no longer overlaps with the other component, it loses its magnetic force, causing the nickel component to fall into another discharge port.

[0075] In a preferred embodiment of the present invention, a waste metal inlet channel 44 is provided above the roller 7, and the upper end of the waste metal inlet channel extends to one side of the material cylinder 2.

[0076] As a preferred embodiment of the present invention, both the first net 11 and the second net 12 are provided with guide plates 35, which can effectively prevent the material in the net from falling outside the material cylinder during the flipping process.
