[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0021] In some embodiments of the present invention, a scrapped vehicle waste treatment device is disclosed, comprising: a soaking mechanism, comprising a barrel 2 and a barrel 3 for cleaning metal and ABS plated parts, respectively, and a barrel 3 13 for deplating ABS plated parts. The barrel 1 2 and the barrel 2 3 are respectively provided with a net bag 1 11 and a net bag 2 12 for containing a solid phase. The waste liquid collection area arranged below the soaking mechanism comprises a container 5 for collecting the liquid phase discharged from the barrel 1 2 and the barrel 2 3, and a container 2 6 for collecting the liquid phase discharged from the barrel 3 13. A drying mechanism comprises a roller 1 7 and a roller 2 9 for receiving the cleaned metal and ABS plated parts, respectively, and a heating channel 15 surrounded by the outside of the roller 1 7 and the roller 2 9. And, a pyrolysis furnace 8, for receiving the dried ABS plated parts, separating the ABS plated parts by pyrolysis, retaining and collecting the metal coating thereon, and the exhaust gas of the pyrolysis furnace 8 is output to the heating channel 15.

[0022] The above device can be operated according to the following steps: In the initial state, the scrapped car can be subjected to preliminary mechanical disassembly, which can be done manually or by hand. The specific process can refer to conventional techniques in the art, and this application will not repeat it in detail.

[0023] After collecting the raw materials, the scrap metal parts can be placed in the net bag 11 of the barrel 2, and the ABS plated parts or other plastic parts with metal layers can be placed in the net bag 12 of the barrel 3, and soaked and cleaned respectively. The metal layer generally includes chromium, nickel, etc., which is usually used to enhance the gloss or service life of the interior decoration parts. The main cleaning objects include oil stains generated by long-term use.

[0024] After soaking, the net bag 11 can be rotated to salvage the metal parts. After the net bag 11 is turned 180 degrees, the metal parts can be poured into the drum 7 to wait for the next drying process. For ABS plated parts, after cleaning, they need to be soaked in the next step. Similarly, the net bag 2 12 is turned by rotating the shaft 21. The ABS plated parts are poured into the barrel 3 13. Unlike the barrel 2 3, a deplating agent can be added to the barrel 3 13, not for the oil stains therein, but for the metal coating on the ABS plated parts. The deplating process is also soaking, and the metal ions therein are separated from the ABS and enter the liquid phase by acid. The acid can be hydrochloric acid. At this time, the chromium and nickel metal coatings can be converted into chromium chloride and nickel chloride. Some powder deplating agents such as chelating agents can also 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.

[0025] At this time, the solid phase is salvaged or filtered out to complete the preliminary stripping. The remaining liquid phase enters the container 2 6, and at this time, an alkali such as sodium hydroxide can be further added to the liquid phase to precipitate the chromium ions and nickel ions therein, and the preliminary separation of the metal components is completed after the precipitate is salvaged or filtered.

[0026] At this time, the remaining solid phase in the barrel three 13 can enter the drum two 9 for drying.

[0027] Due to oxidation of the metal layer in the ABS plated parts, conventional immersion stripping may still not be able to fully complete the extraction of the metal. In order to further increase the efficiency of extraction, in some embodiments of the present application, after the drying treatment of the drum 2 9, the solid phase dried by the drum 2 9 is pyrolyzed or cracked.

[0028] Specifically, the solid phase can be fed into a pyrolysis furnace 8, wherein the temperature of the pyrolysis furnace 8 can be set to 300 degrees Celsius to 600 degrees Celsius. Within this temperature range, other plastic parts such as ABS plated parts can be fully gasified. At the same time, a protective gas needs to be added to avoid undesirable reactions, such as oxidation of the metal. When the cracking is completed, the remaining powder solid phase contains the remaining metal components, and the separation of the metal components from the ABS is completed.

[0029] It should be noted that in the process of the present application, drying is also a necessary step, and the waste gas output by cracking can be used for drying. Specifically, the pyrolysis furnace 8 is connected to the heating channel 15 through the exhaust pipe 1 25. Since the heating channel 15 surrounds the outer wall of the drum 1 7 and the drum 2 9, and the temperature in the pyrolysis furnace 8 is higher than 100 degrees Celsius, there may be cooling in the process of passing through the exhaust pipe 1 25, but it can also be easily increased through heat conduction. The temperature of the drum 1 7 and the drum 2 9 achieves the drying effect. Of course, it should be noted that the gas from the high-temperature decomposition of plastic parts such as ABS often requires further treatment, which means that the heating channel 15 cannot be directly connected to the drum 1 7 and the drum 2 9, or connected to the external environment, but requires further waste gas treatment, which can be the existing waste gas treatment, or the subsequent spray mechanism treatment of this application.

[0030] The preferred embodiments of the present invention will be further disclosed below to further optimize the functions of the device of the present application.

[0031] As a preferred embodiment of the present invention, the barrel 1 2, barrel 2 3 and barrel 3 13 are arranged side by side in sequence, and the net bag 1 11 is rotatably connected to the upper end surface of the barrel 1 2. The connection between the barrel 2 3 and the barrel 3 13 is rotatably connected with a rotating shaft 1 21, and the rotating shaft 1 21 is fixedly connected with the net bag 2 12. A gear 28 is coaxially fixedly installed on the rotating shaft 1 21, and a connecting rod 30 is slidably connected to the inner wall of the barrel 2 3, and a vertically arranged rack 29 is fixedly installed on the connecting rod 30, and the rack 29 is meshed with the gear 28. A sealing member is fixedly installed at the lower end of the connecting rod 30 for sealing the drainage port on the bottom surface of the barrel 2 3. The barrel 2 3 can be connected to the container 1 5 through the drainage port.

[0032] When the soaking is completed, the material in the barrel 23 needs to be transferred. Specifically, the rotating shaft 1 21 can be driven to rotate manually or by a motor or a cylinder, so that the net bag 2 12 is dumped, and the material in the net bag 2 12 falls into the barrel 3 13. While the rotating shaft 1 21 rotates, the gear 28 thereon rotates synchronously, driving the rack 29 to rise. At this time, the connecting rod 30 also moves up synchronously, so that the seal originally sealed on the drain port moves up. In this way, when the soaking is completed, the pouring of the solid phase material is completed, and the discharge of the remaining liquid phase is also completed, that is, it is discharged into the container 1 5 through the drain port. Conversely, when the rotating shaft 1 21 rotates in the opposite direction, the net bag 2 12 is reset to prepare to receive the next batch of ABS plated parts. Similarly, the waste liquid discharge port of the barrel 2 3 after cleaning and soaking, the seal re-seals the drain port, and new cleaning liquid can be added at this time.

[0033] In other embodiments of the present invention, the above barrel layout and the flipping action of the net bag 2 12 are also applied. Specifically, a silo 4 for accommodating and supplying a deplating agent to the barrel 3 13 is provided above the barrel 3 13. A discharging roller is provided at the discharging port of the silo 4. The barrel 1 2, the barrel 2 3 and the barrel 3 13 are arranged side by side in sequence, and the net bag 1 11 is rotatably connected to the upper end surface of the barrel 1 2. A rotating shaft 21 is rotatably connected at the connection between the barrel 2 3 and the barrel 3 13, and 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 barrel 2 3, and a ratchet 40 is provided on the inner wall of the turntable 31. The pawl 41 can mesh with the ratchet 40 to form a ratchet mechanism. A pulley 33 is coaxially fixedly installed on the turntable 31, and a pulley 2 34 is rotatably connected to the outer wall of the silo 4. The pulley 2 34 is coaxially fixedly connected to the feeding roller shaft, and the pulley 1 33 and the pulley 2 34 are connected through a transmission belt 32.

[0034] Similar to the above embodiment, after the immersion of the barrel 2 3 is completed, the rotation of the shaft 1 21 in this embodiment also drives the net bag 2 12 to rotate and dump. While the shaft 1 21 rotates, the ratchet 41 can push the ratchet 40 on the turntable 31 to rotate, thereby driving the turntable 31 to rotate, the pulley 1 33 on the turntable 31 to rotate, and the pulley 2 34 and the discharge roller thereon to rotate, so that the powdered deplating agent stored in the silo 4 is output to the barrel 2 3.

[0035] That is, since a ratchet mechanism is formed between the rotating shaft 21 and the rotating disk 31 , when the rotating shaft 21 is tilted, the discharging roller is driven to rotate, and the powdered deplating agent is brought out of the silo 4 .

[0036] At this time, attention should be paid to the flipping angle and position of the net bag 12 to avoid interfering with the output of the stripping agent.

[0037] As a preferred embodiment of the present invention, a sealing plate 16 is provided between the barrel 3 13 and the container 2 6, and the sealing plate 16 is used to close the opening of the bottom surface of the barrel 3 13. Symmetrical and horizontally arranged slide rails 26 are provided on both sides of the opening of the barrel 3 13, and one end of the slide rail 1 26 is connected to an arc-shaped slide rail 2 27. A waste liquid inlet and an ABS plated part inlet are provided on the container 2 6, and the slide rail 2 27 extends downward to the top of the ABS plated part inlet. One end of the sealing plate 16 can be selectively slidably connected to the slide rail 1 26 and the slide rail 2 27. The other end of the sealing plate 16 is movably connected to the slide rail 1 26. A filter screen 17 is embedded in the sealing plate 16.

[0038] Although the sealing plate 16 is in sliding connection, in the initial state, the filter screen 17 on the sealing plate 16 is not within the range of the opening, that is, the opening is closed, and the solid part of the sealing plate 16 is tightly attached to the joint of the opening, maintaining a sealed sliding connection. When the stripping is completed, the metal enters the liquid phase in the form of ions. At this time, it is expected that the solid phase and the liquid phase will be initially separated. At this time, the sealing plate 16 is horizontally slid so that the part of the filter screen 17 on the sealing plate 16 overlaps with the opening of the barrel three 13 in the vertical direction. At this time, the liquid phase can enter the inlet of the container two 6 through the filter screen 17. In this state, the two ends of the sealing plate 16 are still on the slide rail one 26, and the sealing plate 16 is still attached to the opening, but the filter screen 17 enters the opening, so that the liquid phase can be discharged, and the solid phase is still deposited on the filter screen 17 and the sealing plate 16.

[0039] At this time, the sealing plate 16 is further pushed, and one end of the sealing plate 16 moves to the end of the slide rail 1 26, that is, the connection between the slide rail 1 26 and the slide rail 2 27. At this time, the end of the sealing plate 16 is subjected to the effect of gravity and slides downward along the slide rail 27. In this way, the end located on the slide rail 27 begins to move away from the opening, so that the solid phase deposited on the sealing plate 16 also escapes from the barrel 3 13 and pours downward into the roller 2 9 below.

[0040] As a preferred embodiment of the present invention, it also includes a spray mechanism for treating the waste gas generated by the pyrolysis furnace 8. The spray 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.

[0041] The air inlet is connected to the gas outlet of the heating channel 15 .

[0042] As a preferred embodiment of the present invention, it also includes a frame 1, on which a sprocket 19 and a pair of sprockets 2 18 are rotatably connected, and the pair of sprockets 2 18 are respectively arranged below the roller 1 7 and the roller 2 9. The sprocket 19 is arranged below the housing 10, and the rotating shaft 22 is coaxially fixedly connected with the sprocket 19.

[0043] The drum 1 7 and the drum 2 9 are both provided with stirring blades, and the stirring blades are fixedly connected to the sprocket 2 18. The sprocket 1 19 is connected to the pair of sprockets 2 18 through a transmission chain 20.

[0044] In this embodiment, due to the meshing of sprocket 19 and sprocket 2 18, when the stirring blades of drum 1 7 rotate, the stirring blades of drum 2 9 and shaft 2 22 rotate synchronously. Specifically, the power source of the above-mentioned drive can be set on sprocket 1 19 or on shaft 1 21, and those skilled in the art can adjust it according to needs.

[0045] That is to say, when drying, the stirring blades rotate to stir the materials inside the drum 1 7 and the drum 2 9, thereby accelerating the drying speed. At the same time, the rotating shaft 22 can be driven to rotate, thereby driving the rotating arm 24 to continuously rotate, thereby realizing rotary spraying and improving the working efficiency of the spraying mechanism.

[0046] As a preferred embodiment of the present invention, a sorting mechanism is arranged below the outer shell 10, including a cylinder 39, a magnetic separation roller 42 and an arc-shaped magnetic pole 43. A rotating shaft 38 is coaxially fixedly installed at both ends of the magnetic separation roller 42. The rotating shaft 38 is rotatably connected to the cylinder 39. A worm gear 37 is coaxially fixedly installed on the rotating shaft 38. A worm 36 is coaxially fixedly installed at the lower end of the rotating shaft 22, and the worm gear 37 is meshed with the worm 36.

[0047] In this way, when the second rotating shaft 22 rotates, in addition to driving the rotating arm 24 to rotate and perform spraying, the worm 36 can also drive the worm wheel 37 to drive the rotating shaft 38 and the magnetic separation drum 42 thereon to rotate. At this time, the dried precipitate or the solid phase left after cracking in the pyrolysis furnace 8 is added to the feed port of the cylinder 39, and the magnetic pole 43 generates a magnetic field, which will absorb the nickel component therein, and the other components will fall into a discharge port below. When the part of the magnetic separation drum 42 that absorbs the nickel metal component rotates to no longer overlap, it loses its magnetic force, causing the nickel metal component to fall into another discharge port.

[0048] As 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 barrel 2.

[0049] As a preferred embodiment of the present invention, both the net bag 1 11 and the net bag 2 12 are provided with guide plates 35, which can effectively prevent the materials therein from falling outside the barrel during the turning process of the net bags.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
