Description

Technical Field

[0001] The present invention relates to the technical field of electronic component recycling, and in particular to an electronic component recycling management device and a recycling method thereof. Background Art

[0002] Electronic waste contains a large amount of hazardous substances, such as lead, cadmium, mercury and brominated flame retardants, which pollute the soil, water sources and atmosphere and harm the ecosystem. By recycling electronic components, the accumulation of these wastes can be reduced and further damage to the environment can be avoided. Electronic components contain rare and precious metals, such as gold, silver, palladium and platinum. The mining and refining of these metals not only consumes a lot of resources, but also causes environmental pollution. Recycling these materials can reduce dependence on original mineral resources and reduce the ecological damage caused by mining. The precious and rare metals contained in electronic components have high economic value. Through recycling, the material cost of manufacturing new electronic equipment can be reduced, and sustainable economic development can be promoted by recycling metals. Recycling metals consumes less energy than extracting metals from raw ores. The process of recycling metals such as aluminum and copper is more energy-efficient than mining and smelting new metals. Many countries have introduced laws and regulations on electronic waste management, requiring electronic product manufacturers, sellers and users to recycle and safely dispose of discarded electronic products. Compliance with the recycling of electronic components can not only reduce the legal risks of enterprises, but also reflect the social responsibility of enterprises. As society's environmental awareness increases, companies and consumers are paying more and more attention to product life cycle management. Sustainable use of resources through recycling has also become an important means to enhance the corporate image.

[0003] Pyrolysis is the process of decomposing organic matter in electronic waste into combustible gases and residues through high temperatures, while incineration is used to burn plastics and other organic materials, leaving behind metals and inorganic matter. During the incineration process, an exhaust gas purification device is equipped to prevent the emission of toxic gases such as dioxins. Some recycling processes directly melt waste electronic components through high-temperature smelting methods to separate metals and non-metallic materials, which is particularly suitable for processing electronic waste containing precious metals. With the improvement of environmental protection standards, the use of more environmentally friendly and sustainable recycling technologies has become a trend. For example, metal recovery is carried out using bioleaching technology (extracting metals through microorganisms) or more environmentally friendly chemical reagents. Use artificial intelligence and robotics technology to disassemble and sort electronic waste to improve recycling efficiency and accuracy.

[0004] For example, the Chinese authorized patent "System and method for separating electronic components from waste circuit boards by high-frequency induction heating" with application number CN201110335418.4 includes: high-frequency induction heating coil, circuit board fixing clip, vibrating component recovery net, solder recovery box, vacuum pump, harmful gas treatment box, vent, openable box cover, vibration motor, induction coil control box, shell, rear cover; the waste circuit board is clamped on the circuit board fixing clip, and the solder at the pins connecting the electronic components and the substrate is heated and melted by the high-frequency induction heating device, and the electronic components are separated from the substrate by the circuit board fixing clip. The components and solder that fall off fall onto the vibrating component recovery net, and the vibrating recovery net separates the solder from the components through vibration and continues to fall into the solder recovery box for recycling. The present invention has the characteristics of fast and efficient separation of electronic components.

[0005] Although the above-mentioned prior art has certain progress, many existing electronic components have plastic products on their surfaces for protection or identification. If the plastic products are not cleaned, subsequent disassembly and recycling work cannot be carried out.

[0006] In view of the above situation, in order to overcome the above technical problems, the present invention designs an electronic component recycling management device and a recycling method thereof, which solves the above technical problems. Summary of the invention

[0007] The technical purpose to be achieved by the present invention is to provide an electronic component recycling management device and a recycling method thereof, so as to reduce the nitrogen oxides generated during the recycling process of electronic components, thereby complying with national emission standards and further protecting the environment.

[0008] In order to achieve the above technical objectives, the present invention provides the following technical solutions:

[0009] An electronic component recycling management device includes a bracket, a discharge port, a recycling mechanism, a control mechanism and a regulating valve, and has an ingenious structural design and comprehensive functions. Specifically, the bracket is the basic supporting structure of the entire device, and the discharge port is arranged on the side of the bracket, which is used to discharge the processed materials in time during the recycling process. The recycling mechanism is installed on the upper part of the bracket. As a core device, its function is to perform high-temperature smelting on electronic components. Through high-temperature smelting, the recycling mechanism can effectively remove plastic products on the surface of electronic components, thereby realizing material separation. The control mechanism is installed on the top of the recycling mechanism and is responsible for adjusting the entire recycling process. In order to further improve the recycling efficiency and reduce the impact on the environment, a reflux component is provided in the device. The component can reflux the flue gas generated during the high-temperature smelting process to realize the secondary utilization of the flue gas. Specifically, the flue gas generated by combustion re-enters the combustion chamber through the reflux component for secondary combustion, which not only reduces exhaust gas emissions, but also effectively reduces environmental pollution. The regulating valve is installed at one end of the control mechanism, and the flow rate of the reflux flue gas is adjusted by the command of the control mechanism. The control mechanism precisely controls the opening and closing of the regulating valve by real-time monitoring of the air pressure in the combustion chamber and the reflux pipe, thereby achieving flue gas reflux regulation of different flow rates. This precise control can not only ensure the full combustion of electronic components, but also reduce the generation of nitrogen oxides. This is very beneficial to environmental protection, because nitrogen oxides are an important source of air pollution. By recirculating and secondary burning the flue gas, not only the fuel consumption is reduced, but also the overall energy utilization rate is improved, making the recycling process more energy-saving and environmentally friendly. Overall, this electronic component recycling management device has significant advantages in improving recycling efficiency, reducing environmental pollution, and saving energy.

[0010] The recovery mechanism includes a feed port, a combustion chamber, a smoke outlet and a reflux assembly. The feed port is located at the upper part of the recovery mechanism, and the material to be processed can be fed into the recovery device through the feed port. The combustion chamber is arranged in the middle of the recovery mechanism, and is used for high-temperature combustion or decomposition treatment of the material. The smoke generated during the combustion process will be discharged through the smoke outlet located at the upper part of the recovery mechanism, thereby ensuring the smooth progress of the combustion process. In order to further improve the combustion efficiency and reduce exhaust gas emissions, the reflux assembly is installed on the side of the recovery mechanism, and by returning part of the incompletely burned gas or heat to the combustion chamber for secondary treatment, the utilization rate of resources is effectively improved and environmental pollution is reduced.

[0011] The reflux assembly is composed of multiple key components, including a reflux pipe, a ventilation block, a smoke detection pipe and a reflux detection pipe. The reflux pipe is the core component of the assembly and is installed on the side of the recovery mechanism. Its two ends are respectively connected to the smoke outlet and the combustion chamber to ensure that the smoke can be effectively circulated during the treatment process. Two ventilation blocks are installed on the reflux assembly, both located on the side of the control mechanism. The ventilation block plays the role of connecting ventilation to ensure that the smoke detection pipe and the reflux detection pipe can flow gas normally with the control mechanism. One end of the smoke detection pipe is connected to the ventilation block, and the other end is connected to the part between the regulating valve and the smoke outlet of the reflux pipe. Through the flow of smoke, the regulating effect on the regulating valve is realized. One end of the reflux detection pipe is also connected to the ventilation block, and the other end is installed in the other side of the reflux pipe. These components cooperate with each other, which can not only improve the working efficiency of the entire recovery system, but also optimize the combustion process and reduce pollution emissions.

[0012] The control mechanism is composed of multiple components, including a mounting component, a control cylinder, a fixing component and a switch component. First, the mounting component is located above the recovery mechanism. As the basic part of the entire control mechanism, it provides installation positions for various components. The control cylinder is installed inside the mounting component, which plays a core control role, carrying and protecting the internal control equipment. The fixing component is installed on the side of the mounting component, and has the functions of fixing and supporting to ensure that the control mechanism maintains stability during operation. The switch component is arranged inside the control cylinder, through which the regulating valve can be controlled. These parts work together to enable the control mechanism to effectively adjust and control the operation of the recovery mechanism to ensure safety and stability.

[0013] The installation assembly consists of a mounting block, a through hole, a mounting cavity and a mounting ring cavity, and has a sophisticated structure and complete functions. The mounting block is the core structure of the entire installation assembly, which is fixed to the upper part of the recovery mechanism and is used to support and connect other components. The through hole is arranged on the side of the mounting block, and the mounting cavity is located in the middle part of the mounting block. It is the main accommodation space for internal equipment or components, providing sufficient space for subsequent component installation. The mounting ring cavity is arranged on the side of the mounting cavity to form an annular accommodation area for accommodating and fixing some auxiliary components or accessories. The various parts are closely matched to ensure that the entire installation assembly structure is stable and has good functionality, providing a solid foundation for the normal operation of the recovery mechanism.

[0014] The control tube has a complex and delicate structure, including multiple components such as a fixed ring, a control sleeve, a control flow channel, a connecting hole, a through sleeve, a sealing groove and a gas through port. The fixed ring is a key supporting component of the control tube, which is installed inside the mounting assembly and is used to firmly connect the control tube to the entire recovery mechanism. The control sleeve is located below the fixed ring and is one of the core components, which plays a role in guiding and controlling the airflow. The control flow channel is opened on the side wall of the control sleeve for the flow and conduction of the gas to ensure that the gas can pass through the equipment smoothly. The connecting hole is located at one end of the control flow channel close to the fixed ring, connecting the airflow between the flow channel and other components, and further optimizing the gas flow path. The through sleeve is installed in the middle position of the fixed ring to play a guiding and positioning role. The sealing groove is opened on the side of the control sleeve to ensure the sealing inside the equipment and effectively prevent gas leakage. Finally, the gas through port is located in the central position of the bottom of the control sleeve to ensure that the gas can pass through the bottom area smoothly and enter the subsequent processing steps.

[0015] The fixing assembly is a highly functional and exquisitely designed assembly, including a fixing plate, a transition cavity, a sealing rubber ring, a No. 1 air hole and a No. 2 air hole. The fixing plate is the main structural part of the fixing assembly, which is installed on the side of the mounting assembly and is used to firmly fix other components. The transition cavity is opened on the inner side of the fixing plate, as a transition area, allowing gas or material to smoothly transition to other components. The sealing rubber ring is set on the inner side of the transition cavity. Its main function is to provide sealing, prevent leakage of gas or liquid, and ensure the sealing and stability of the entire system.

[0016] The No. 1 air hole is located in the middle of the fixed disk and is the main channel for gas to enter and exit the fixed component. The gas can be circulated or discharged through this air hole. The No. 2 air hole is set on the surface of the fixed disk as another gas channel, working together with the No. 1 air hole. These designs enable the fixed component to not only stably support and fix other components in structure, but also effectively control the gas flow to ensure the efficient operation and sealing of the system. The structural design of the entire fixed component focuses on the combination of function and practicality, ensuring the efficient operation and safety performance of the recovery mechanism.

[0017] The structural design of the switch assembly includes multiple important parts, among which the soft collar, piston rod, vent hole and control ball are key components. Specifically, the soft collar is installed inside the control sleeve to provide support and guidance for the piston rod. The piston rod is precisely installed inside the soft collar to ensure its stability and accuracy during operation. In order to achieve the ventilation function, the vent hole is opened in the middle part of the piston rod. This design allows the gas to pass smoothly without obstruction. In addition, the control ball is set at the other end of the piston rod. Its main function is to serve as the core element of the switch operation, and to achieve precise control of the switch state through its movement or position change. This design enables the entire switch assembly to have excellent functionality and reliability, and can show good performance and stability in practical applications.

[0018] The regulating valve is a complex and sophisticated device, mainly composed of a regulating block, a sliding groove and a mounting hole. The regulating block is the core component of the device, which is installed on the top of the recovery mechanism to ensure the stability of the device and the normal operation of the function. Inside the regulating block, a sliding groove is opened, which is designed in a "bullet head" shape. This shape of design helps the switch assembly to slide in it and reduce resistance. The shape of the sliding groove also facilitates smooth sliding inside the regulating block. In addition to the sliding groove, vertical sliding grooves are also opened in the regulating block. These grooves are located on the inner side of the regulating block, allowing adjustments in the vertical direction, thereby achieving precise control of the fluid flow. Through these fine structural designs, the regulating valve can maintain stability under various operating conditions and ensure the efficient operation of the system.

[0019] A method for recycling electronic components, which is used in conjunction with the above-mentioned electronic component recycling management device; the steps of the method are as follows:

[0020] S1: Classify discarded electronic components by type, such as circuit boards, electronic devices, capacitors, resistors, chips, etc., manually or mechanically disassemble electronic products, remove large non-metal parts (such as casings, cables, etc.), and leave core components;

[0021] S2: Remove flammable and hazardous substances, such as batteries, from disassembled electronic components to avoid explosion or release of harmful gases during combustion;

[0022] S3: electronic components are fed into the combustion chamber through the feed port, and the combustion temperature is controlled (about 500°C to 800°C) to ensure that plastics and other organic materials are fully burned. During combustion, a control mechanism is used to control the regulating valve to achieve flue gas reflux, thereby achieving secondary combustion and reducing the generation of nitrogen oxides;

[0023] S4: The smoke outlet is connected to a filtering system to capture toxic smoke and harmful gases (such as dioxins) to ensure that they are harmless to the environment. The ash left after combustion will contain metal residues and other high-temperature resistant materials;

[0024] S4: Use magnetic separation equipment to separate magnetic metals such as iron and nickel. For non-magnetic metals (such as copper, aluminum, gold, etc.), eddy current separation technology or manual sorting methods can be used for further separation. For precious metals (such as gold, silver, platinum, etc.), hydrometallurgical treatment such as leaching (using acid or alkali solution) can be used to dissolve and extract the metal, and the extracted metal solution can be electrolyzed or further purified to obtain high-purity metal.

[0025] S5: Ashes produced by combustion can be further utilized, such as used as building materials, or landfilled after harmless treatment. Residual plastics and other non-metallic materials can be disposed of by landfill or incineration.

[0026] The beneficial effects of the present invention are as follows:

[0027] 1. The present invention uses a recovery mechanism to recycle the flue gas generated by combustion. Through the flue gas circulation, the unburned gas enters the combustion chamber again for secondary combustion, further releasing energy, and improving the overall combustion efficiency of the fuel. Since the secondary combustion can more thoroughly utilize the chemical energy in the fuel, this reduces fuel waste, thereby reducing fuel consumption. Since the combustion temperature is more uniform and relatively low, it helps to reduce the generation of nitrogen oxides during the combustion process. Nitrogen oxides are an important source of air pollution, and reducing their emissions is of great significance for reducing acid rain and photochemical smog. Secondary combustion can further decompose and burn tiny carbon particles and other incompletely burned components in the flue gas, reducing the emission of smoke and particulate matter. Carbon monoxide is a toxic gas that is usually produced by incomplete combustion. Through secondary combustion, carbon monoxide can be further oxidized to carbon dioxide, reducing the emission of harmful gases. Flue gas circulation can recycle the incompletely utilized heat in the flue gas, further improving the energy efficiency of the entire system. This can reduce the demand for external fuel and reduce overall energy consumption. Secondary combustion can not only utilize unburned fuel, but also reduce the temperature of the exhaust gas, reduce the loss of sensible heat, and improve the utilization rate of thermal energy.

[0028] 2. The present invention is provided with a control mechanism and a regulating valve, which controls the rate of flue gas reflow by detecting the pressure in the combustion chamber and the reflow pipe, and ensures that the combustion chamber maintains ideal combustion conditions, including suitable temperature and oxygen supply. This helps to avoid burning too fast or too slow, ensure the full combustion of organic matter (such as plastic) in electronic components, and the effective separation of metals and other materials. By real-time monitoring of pressure and adjusting flue gas reflow, the supply of oxygen can be adjusted during the combustion process to ensure that all flammable components burn under optimal conditions and reduce the generation of unburned carbon, hydrocarbons and other residues. By accurately adjusting the flue gas reflow, the appropriate combustion temperature is maintained. Higher temperatures increase the generation of nitrogen oxides, while lower temperatures lead to incomplete combustion. Controlling the flue gas reflow rate can maintain a low and uniform combustion temperature, thereby effectively reducing the generation of nitrogen oxides. Incompletely burned particulate matter and carbon monoxide emissions can be reduced by adjusting the flue gas reflow rate. During the combustion process, if the temperature in the combustion chamber is too high, it may cause damage to equipment (such as a combustion furnace, a heat exchanger). By monitoring the pressure to adjust the flue gas reflow rate, the temperature can be better controlled, the equipment can be prevented from being damaged due to overheating, and the service life of the equipment can be extended. Controlling the flue gas reflow rate can reduce the accumulation of unburned materials in the combustion chamber and pipeline during the combustion process, thereby reducing carbon deposition and corrosion, and reducing maintenance costs.

[0042] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0043] like Figure 1-10, an electronic component recycling management device comprises a bracket 1, a discharge port 2, a recycling mechanism 3, a control mechanism 4 and a regulating valve 5, with an ingenious structural design and comprehensive functions. Specifically, the bracket 1 is the basic supporting structure of the entire device, and the discharge port 2 is arranged on the side of the bracket 1, which is used to discharge the treated materials in time during the recycling process. The recycling mechanism 3 is installed on the upper part of the bracket 1, as a core device, and its function is to perform high-temperature smelting on electronic components. Through high-temperature smelting, the recycling mechanism 3 can effectively remove plastic products on the surface of electronic components, thereby realizing material separation. The control mechanism 4 is installed on the top of the recycling mechanism 3 and is responsible for adjusting the entire recycling process. In order to further improve the recycling efficiency and reduce the impact on the environment, a reflux component 34 is provided in the device. This component can reflux the flue gas generated during the high-temperature smelting process to realize the secondary utilization of the flue gas. Specifically, the flue gas generated by combustion re-enters the combustion chamber 32 through the reflux component 34 for secondary combustion, which not only reduces exhaust gas emissions, but also effectively reduces environmental pollution. The regulating valve 5 is installed at one end of the control mechanism 4, and the flow rate of the reflux flue gas is adjusted by the command of the control mechanism 4. The control mechanism 4 accurately controls the opening and closing of the regulating valve 5 by real-time monitoring of the air pressure in the combustion chamber 32 and the reflux pipe 341, thereby realizing the reflux regulation of flue gas of different flow rates. Through this precise control, not only can the full combustion of electronic components be ensured, but also the generation of nitrogen oxides can be reduced. This is very beneficial to environmental protection, because nitrogen oxides are an important source of air pollution. By recirculating and secondary burning the flue gas, not only the fuel consumption is reduced, but also the overall energy utilization rate is improved, making the recycling process more energy-saving and environmentally friendly. Overall, this electronic component recycling management device has significant advantages in improving recycling efficiency, reducing environmental pollution, and saving energy.

[0044] like Figure 2 As shown, the recovery mechanism 3 includes a feed port 31, a combustion chamber 32, a smoke outlet 33 and a reflux component 34. Among them, the feed port 31 is located at the upper part of the recovery mechanism 3, and the material to be processed can be sent into the recovery device through the feed port 31. The combustion chamber 32 is arranged in the middle position of the recovery mechanism 3, which is used for high-temperature combustion or decomposition treatment of the material. The smoke generated during the combustion process will be discharged through the smoke outlet 33 located at the upper part of the recovery mechanism 3, thereby ensuring the smooth progress of the combustion process. In order to further improve the combustion efficiency and reduce exhaust gas emissions, the reflux component 34 is installed on the side of the recovery mechanism 3, and by returning part of the incompletely burned gas or heat to the combustion chamber 32 for secondary treatment, the utilization rate of resources is effectively improved and environmental pollution is reduced.

[0045] like Figure 3As shown, the reflux assembly 34 is composed of multiple key components, including a reflux pipe 341, a ventilation block 342, a smoke detection pipe 343 and a reflux detection pipe 344. The reflux pipe 341 is the core component of the assembly, which is installed on the side of the recovery mechanism 3, and its two ends are respectively connected to the smoke outlet 33 and the combustion chamber 32 to ensure that the smoke can be effectively circulated during the treatment process. Two ventilation blocks 342 are installed on the reflux assembly 34, both located on the side of the control mechanism 4. The ventilation block 342 plays the role of connecting ventilation, ensuring that the smoke detection pipe 343 and the reflux detection pipe 344 can normally flow gas with the control mechanism 4. One end of the smoke detection tube 343 is connected to the ventilation block 342, and the other end is connected to the part between the regulating valve 5 and the smoke outlet 33 of the return pipe 341. The regulating effect on the regulating valve 5 is achieved through the flow of smoke. One end of the reflux detection tube 344 is also connected to the ventilation block 342, and the other end is installed in the other side of the reflux pipe 341. These components cooperate with each other, which can not only improve the working efficiency of the entire recovery system, but also optimize the combustion process and reduce pollution emissions.

The fixing component 43 is installed on the side of the mounting component 41, and has the functions of fixing and supporting to ensure that the control mechanism 4 maintains stability during operation. The switch component 44 is arranged inside the control cylinder 42, and the regulating valve 5 can be controlled by this component. These parts work together to enable the control mechanism 4 to effectively adjust and control the operation of the recovery mechanism 3 to ensure safety and stability.

[0047] like Figure 5 As shown, the mounting assembly 41 is composed of a mounting block 411, a through hole 412, a mounting cavity 413 and a mounting annular cavity 414, and is exquisitely constructed and fully functional. The mounting block 411 is the core structure of the entire mounting assembly 41, which is fixed to the upper part of the recovery mechanism 3 and is used to support and connect other components. The through hole 412 is arranged on the side of the mounting block 411, and the mounting cavity 413 is located in the middle part of the mounting block 411. It is the main accommodation space for internal equipment or components, and provides sufficient space for subsequent component installation. The mounting annular cavity 414 is arranged on the side of the mounting cavity 413 to form an annular accommodation area for accommodating and fixing some auxiliary components or accessories. The various parts are closely matched to ensure that the entire mounting assembly 41 has a stable structure and good functionality, providing a solid foundation for the normal operation of the recovery mechanism 3.

The fixing ring 421 is a key supporting component of the control tube 42, which is installed inside the mounting assembly 41 and is used to firmly connect the control tube 42 to the entire recovery mechanism 3. The control sleeve 422 is located below the fixing ring 421 and is one of the core components, which plays a role in guiding and controlling the airflow. The control flow channel 423 is opened on the side wall of the control sleeve 422 for the flow and conduction of gas to ensure that the gas can pass through the equipment smoothly. The connecting hole 424 is located at one end of the control flow channel 423 close to the fixing ring 421, connecting the airflow between the flow channel and other components, and further optimizing the gas flow path.

Finally, the gas passage 427 is located at the center of the bottom of the control sleeve 422 to ensure that the gas can smoothly pass through the bottom area and enter the subsequent processing steps.

[0049] The fixing assembly 43 is a highly functional and exquisitely designed assembly, including a fixing plate 431, a transition cavity 432, a sealing rubber ring 433, a No. 1 air hole 434 and a No. 2 air hole 435. The fixing plate 431 is the main structural part of the fixing assembly 43, which is installed on the side of the mounting assembly 41 and is used to firmly fix other components. The transition cavity 432 is opened on the inner side of the fixing plate 431, as a transition area, allowing gas or material to smoothly transition to other components. The sealing rubber ring 433 is arranged on the inner side of the transition cavity 432, and its main function is to provide sealing, prevent leakage of gas or liquid, and ensure the sealing and stability of the entire system.

[0050] like Figure 8 As shown, the No. 1 air hole 434 is located in the middle of the fixed disk 431 and is the main channel for gas to enter and exit the fixed component 43. The gas can be circulated or discharged through this air hole. The No. 2 air hole 435 is set on the surface of the fixed disk 431 as another gas channel, and works together with the No. 1 air hole 434. These designs enable the fixed component 43 to not only stably support and fix other components in structure, but also effectively control the gas flow to ensure the efficient operation and sealing of the system. The structural design of the entire fixed component 43 focuses on the combination of function and practicality, ensuring the efficient operation and safety performance of the recovery mechanism 3.

[0051] like Fig. 9As shown, the structural design of the switch assembly 44 includes multiple important parts, among which the soft collar 441, the piston rod 442, the vent 443 and the control ball 444 are key components. Specifically, the soft collar 441 is installed inside the control sleeve 422 to provide support and guidance for the piston rod 442. The piston rod 442 is precisely installed inside the soft collar 441 to ensure its stability and accuracy during operation. In order to achieve the ventilation function, the vent 443 is opened in the middle part of the piston rod 442. This design allows the gas to pass smoothly without obstruction. In addition, the control ball 444 is set at the other end of the piston rod 442. Its main function is to serve as the core element of the switch operation, and to achieve precise control of the switch state through its movement or position change. This design enables the entire switch assembly 44 to have excellent functionality and reliability, and can show good performance and stability in practical applications.

[0052] like Fig. 9 As shown, the regulating valve 5 is a complex and precise device, which is mainly composed of a regulating block 51, a sliding groove 52 and a mounting hole 53. The regulating block 51 is the core component of the device, which is installed on the recovery mechanism 3 to ensure the stability of the device and the normal operation of the function. Inside the regulating block 51, a sliding groove 52 is provided, and the sliding groove 52 is designed in a "bullet head" shape. This shape design helps the switch assembly 44 to slide therein and reduce resistance. The shape of the sliding groove 52 also facilitates smooth sliding inside the regulating block 51. In addition to the sliding groove 52, vertical sliding grooves 52 are also provided in the regulating block 51. These grooves are located on the inner side of the regulating block 51, allowing adjustment in the vertical direction, thereby achieving precise control of the fluid flow. Through these fine structural designs, the regulating valve 5 can maintain stability under various operating conditions and ensure the efficient operation of the system.

[0053] A method for recycling electronic components, which is used in conjunction with the above-mentioned electronic component recycling management device; the steps of the method are as follows:

[0054] S1: Classify discarded electronic components by type, such as circuit boards, electronic devices, capacitors, resistors, chips, etc., manually or mechanically disassemble electronic products, remove large non-metal parts (such as casings, cables, etc.), and leave core components;

[0055] S2: Remove flammable and hazardous substances, such as batteries, from disassembled electronic components to avoid explosion or release of harmful gases during combustion;

[0056] S3: electronic components are fed into the combustion chamber 32 through the feed port 31, and the combustion temperature is controlled (about 500°C to 800°C) to ensure that the plastic and other organic materials are fully burned. During the combustion, the control mechanism 4 is used to control the regulating valve 5 to realize the flue gas reflux, thereby realizing secondary combustion and reducing the generation of nitrogen oxides;

[0057] S4: The smoke outlet 33 is connected to a filtering system to capture toxic smoke and harmful gases (such as dioxins) to ensure that they are harmless to the environment. The ash left after combustion will contain metal residues and other high-temperature resistant materials;

[0058] S4: Use magnetic separation equipment to separate magnetic metals such as iron and nickel. For non-magnetic metals (such as copper, aluminum, gold, etc.), eddy current separation technology or manual sorting methods can be used for further separation. For precious metals (such as gold, silver, platinum, etc.), hydrometallurgical treatment such as leaching (using acid or alkali solution) can be used to dissolve and extract the metal, and the extracted metal solution can be electrolyzed or further purified to obtain high-purity metal.

[0059] S5: Ashes produced by combustion can be further utilized, such as used as building materials, or landfilled after harmless treatment. Residual plastics and other non-metallic materials can be disposed of by landfill or incineration.

[0060] During the working process of the present invention, the staff classifies the discarded electronic components by type, such as circuit boards, electronic devices, capacitors, resistors, chips, etc., manually or mechanically disassembles the electronic products, removes large non-metallic parts (such as shells, cables, etc.), and leaves the core components; removes flammable and dangerous substances, such as batteries, from the disassembled electronic components to avoid explosion or release of harmful gases during the combustion process; feeds the electronic components into the combustion chamber 32 through the feed port 31, controls the combustion temperature (about 500° C. to 800° C.), ensures that the plastic and other organic materials are fully burned, and during combustion, uses the control mechanism 4 to control the regulating valve 5 to realize flue gas reflux, realizes secondary combustion, and reduces the generation of nitrogen oxides;

[0061] During the combustion process, a large amount of smoke generated in the combustion chamber 32 is discharged from the smoke outlet 33, and a part of it enters the return pipe 341. The air pressure of the return pipe 341 near the smoke outlet 33 increases, and a part of the gas enters the control mechanism 4 through the smoke detection tube 343;

[0062] The gas enters the control sleeve 422 through the ventilation block 342 and the gas through-port 427, driving the piston rod 442 to extend outward, and the gas on the upper part of the piston rod 442 is discharged into the control flow channel 423 through the connecting hole, and finally discharged from the second gas hole 435 to the reflux detection tube 344 through the transition cavity 432. Since the air pressure of the reflux tube 341 in this part connected to the reflux detection tube 344 is relatively low, the smoke will enter the combustion chamber 32 in the reflux tube 341 and be discharged, thereby alleviating the working pressure of the reflux tube 341 and helping the gas to reflux quickly.

[0063] Due to the existence of the soft collar 441, the piston rod 442 will not be close to the bottom of the control sleeve 422, and the soft collar 441 also further improves the sealing of the space on both sides of the piston rod 442; the vent hole 443 and the mounting hole 53 provided on the piston rod 442 partially or completely overlap, and the incompletely burned smoke can enter the combustion chamber 32 again through the return pipe 341 to achieve secondary combustion;

[0064] When the smoke generated by combustion is less, the air pressure in the smoke outlet 33 is lower, the smoke flows in the reverse direction, and the regulating valve 5 is closed to ensure the combustion temperature in the combustion chamber 32 and improve the working efficiency of the combustion.

[0065] The smoke outlet 33 is connected to a filtering system to capture toxic smoke and harmful gases (such as dioxins) to ensure that it is harmless to the environment. The ash left after combustion will contain metal residues and other high-temperature resistant materials; magnetic metals such as iron and nickel are separated by magnetic separation equipment, and non-magnetic metals (such as copper, aluminum, gold, etc.) can be further separated using eddy current separation technology or manual sorting methods; precious metals (such as gold, silver, platinum, etc.) can be treated by hydrometallurgy, such as leaching (using acid or alkali solution), to dissolve and extract the metal, and the extracted metal solution is electrolyzed or further purified to obtain high-purity metal; the ash produced by combustion can be further utilized, such as for building materials, or buried after harmless treatment, and the residual plastics and other non-metallic materials can be finally disposed of by landfill or incineration.
