Description

Technical Field

[0001] This utility model relates to the field of circuit board recycling technology, and in particular to a device for recycling copper metal from waste circuit boards. Background Technology

[0002] In the information age, the number of electronic products has increased rapidly, with smart home appliances, personal computers, and handheld devices being updated at an increasingly faster pace. As a result, electronic waste is growing at a rate as high as 22% per year, making it one of the most difficult solid wastes to manage. The core component of these electronic products—printed circuit boards—contains a large amount of recyclable resources, such as copper, iron, zinc, tin, gold, and silver, some of which have a grade tens or even hundreds of times higher than that of ordinary ores.

[0003] The common method for recycling copper from waste circuit boards is to soak them in a chemical solvent to dissolve the copper, and then electrolyze it to extract the copper from the solvent. However, this process generates harmful gases. Some existing equipment is not sealed during the dissolution process, which causes the harmful gases to be released directly into the air, potentially harming workers and polluting the environment. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a device for recycling copper metal from waste circuit boards.

[0005] This utility model is achieved using the following technical solution: a device for recycling copper metal from waste circuit boards, comprising a base plate, a fixed frame fixedly connected to the top of the base plate, a hydraulic rod fixedly connected to the top of the fixed frame, the output end of the hydraulic rod being sleeved inside the fixed frame, a fixed disk fixedly connected to the output end of the hydraulic rod, a connecting rod slidably connected inside the fixed disk, both ends of the connecting rod penetrating the outer wall of the fixed disk and extending therefrom, a baffle plate fixedly connected to the top of the connecting rod, a sealing cover fixedly connected to the bottom of the connecting rod, a spring fixedly connected to the top of the sealing cover, the top of the spring being fixedly connected to the bottom of the connecting rod, and a vent pipe connected to the top of the sealing cover.

[0006] The above technical solution allows the fixed plate to descend via a hydraulic rod, thereby ensuring a tight seal between the sealing cover and the reaction vessel, preventing the gas produced during the reaction from flowing directly into the air.

[0007] As a further improvement to the above solution, the fixing frame is U-shaped, the hydraulic rod is located at the central axis of the fixing frame, and several connecting rods are provided. The several connecting rods are symmetrically arranged with the fixing plate as the center, and the diameter of the baffle is larger than the diameter of the connecting rod.

[0008] As a further improvement to the above solution, a fixing rod is fixedly connected to the bottom of the sealing cover, and a retaining ring is fixedly connected to the end of the fixing rod away from the sealing cover. A limit ring is provided at the top of the retaining ring, and a mesh cylinder is fixedly connected to the inner wall of the limit ring. The mesh cylinder is sleeved inside the retaining ring.

[0009] The above technical solution is designed to limit the limiting ring by using the retaining ring, thereby preventing the net cylinder from falling out of the retaining ring.

[0010] As a further improvement to the above solution, two fixing rods are provided, which are symmetrically arranged around the center of the sealing cover. The inner diameter of the limiting ring is the same as the inner diameter of the retaining ring, and the outer diameter of the limiting ring is smaller than the outer diameter of the retaining ring.

[0011] As a further improvement to the above solution, a support rod is fixedly connected to the top of the base plate, a placement platform is fixedly connected to the top of the support rod, a reaction vessel is fixedly connected to the top of the placement platform, the top of the reaction vessel is in contact with the bottom of the sealing cap, and an outlet pipe is provided on the outer wall of the reaction vessel.

[0012] As a further improvement to the above solution, a motor is fixedly connected to the top of the base plate, the output end of the motor is rotatably connected to the placement platform, the output end of the motor passes through the bottom of the placement platform and extends into the interior of the reaction vessel, the output end of the placement platform is fixedly connected to a mounting bracket, and a stirring rod is fixedly connected to the top of the mounting bracket.

[0013] Through the above technical solution, the motor drives the mounting frame to rotate, and the mounting frame drives the stirring rod to rotate, which can accelerate the flow of the reaction liquid inside the reaction tank, thereby accelerating the reaction rate.

[0014] As a further improvement to the above solution, the mounting frame is in the shape of a cross, and four stirring rods are provided. The four stirring rods are symmetrically arranged with the mounting frame as the center, and the stirring rods are located outside the limiting ring.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention uses a hydraulic rod to lower a fixed plate. After the fixed plate descends, the connecting rod, baffle, sealing cover, spring, pressure relief pipe, fixing rod, retaining ring, limiting ring, and mesh cylinder also descend due to gravity, allowing the waste circuit boards inside the mesh cylinder to enter the reaction tank and come into contact with the reaction liquid. The baffle prevents the connecting rod from detaching from the fixed plate. When the sealing cover contacts the reaction tank, the hydraulic rod continues to lower the fixed plate, compressing the spring. The spring's reaction force ensures a tighter fit between the sealing cover and the reaction tank, effectively preventing harmful gases generated during the reaction from escaping into the air through the space between the sealing cover and the reaction tank. Connecting the pressure relief pipe to a gas treatment device further prevents untreated harmful gases from diffusing into the air, thus avoiding harm to workers and environmental pollution.

[0017] This invention involves adding waste circuit boards into a mesh tube, then placing the mesh tube into a retaining ring from below the sealing cover. The limiting ring on the mesh tube prevents the mesh tube from falling out of the retaining ring, thus keeping the mesh tube inside the retaining ring at all times. This facilitates the installation and removal of the mesh tube and helps with the loading and unloading of waste circuit boards.

[0018] This invention uses a motor to drive the mounting frame to rotate, which in turn drives the stirring rod to rotate. This accelerates the flow of the reaction liquid inside the reaction vessel, thereby increasing the contact frequency between reactants and improving the reaction rate. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example:

[0028] Please combine Figure 1-5 This embodiment of a device for recycling copper metal from waste circuit boards includes a base plate 1, a fixed frame 2 fixedly connected to the top of the base plate 1, a hydraulic rod 3 fixedly connected to the top of the fixed frame 2, the output end of the hydraulic rod 3 being sleeved inside the fixed frame 2, a fixed disk 4 fixedly connected to the output end of the hydraulic rod 3, a connecting rod 5 slidably connected inside the fixed disk 4, both ends of the connecting rod 5 penetrating through the outer wall of the fixed disk 4 and extending outwards, a baffle 6 fixedly connected to the top of the connecting rod 5, a sealing cover 7 fixedly connected to the bottom of the connecting rod 5, a spring 8 fixedly connected to the top of the sealing cover 7, the top of the spring 8 being fixedly connected to the bottom of the connecting rod 5, and a vent pipe 9 connected to the top of the sealing cover 7.

[0029] The fixed frame 2 is U-shaped, the hydraulic rod 3 is located at the central axis of the fixed frame 2, and there are several connecting rods 5. The connecting rods 5 are symmetrically arranged with the fixed plate 4 as the center. The diameter of the baffle 6 is larger than the diameter of the connecting rods 5.

[0030] A fixing rod 10 is fixedly connected to the bottom of the sealing cover 7. A retaining ring 11 is fixedly connected to the end of the fixing rod 10 away from the sealing cover 7. A limit ring 12 is provided at the top of the retaining ring 11. A mesh cylinder 13 is fixedly connected to the inner wall of the limit ring 12. The mesh cylinder 13 is sleeved inside the retaining ring 11.

[0031] There are two fixing rods 10, which are symmetrically arranged around the center of the sealing cover 7. The inner diameter of the limiting ring 12 is the same as the inner diameter of the retaining ring 11, and the outer diameter of the limiting ring 12 is smaller than the outer diameter of the retaining ring 11.

[0032] A support rod 14 is fixedly connected to the top of the base plate 1. A placement platform 15 is fixedly connected to the top of the support rod 14. A reaction vessel 16 is fixedly connected to the top of the placement platform 15. The top of the reaction vessel 16 is in contact with the bottom of the sealing cover 7. An outlet pipe 17 is provided on the outer wall of the reaction vessel 16.

[0033] A motor 18 is fixedly connected to the top of the base plate 1. The output end of the motor 18 is rotatably connected to the placement platform 15. The output end of the motor 18 passes through the bottom of the placement platform 15 and extends into the interior of the reaction vessel 16. A mounting bracket 19 is fixedly connected to the output end of the placement platform 15. A stirring rod 20 is fixedly connected to the top of the mounting bracket 19.

[0034] The mounting bracket 19 is in the shape of a cross, and four stirring rods 20 are provided. The four stirring rods 20 are symmetrically arranged with the mounting bracket 19 as the center, and the stirring rods 20 are located outside the limiting ring 12.

[0035] The implementation principle of the copper metal recycling device for waste circuit boards in this embodiment is as follows: During use, a solution is added to the reaction tank 16, then the waste circuit board is added to the mesh cylinder 13. The mesh cylinder 13 is then placed inside the retaining ring 11 from below the sealing cover 7. The limiting ring 12 on the mesh cylinder 13 prevents it from falling out of the retaining ring 11, thus keeping the mesh cylinder 13 always inside the retaining ring 11. This facilitates the installation and removal of the mesh cylinder 13 and aids in the loading and unloading of waste circuit boards. Then, the hydraulic rod 3 is activated to descend, which pushes the fixed plate 4 downwards. After the fixed plate 4 descends, the connecting rod 5, baffle 6, sealing cover 7, spring 8, pressure relief pipe 9, fixed rod 10, retaining ring 11, limiting ring 12, and mesh cylinder 13 also descend due to gravity, causing the waste circuit board inside the mesh cylinder 13 to enter the reaction tank 16. The waste circuit board will come into contact with the reaction liquid, and the baffle 6 prevents it from falling out of the retaining ring 11. The connecting rod 5 disengages from the fixed plate 4. After the sealing cover 7 contacts the reaction vessel 16, the hydraulic rod 3 continues to push the fixed plate 4 down, which compresses the spring 8. The reaction force of the spring 8 makes the sealing cover 7 fit more tightly with the reaction vessel 16, effectively preventing harmful gases generated by the reaction from escaping into the air through the air between the sealing cover 7 and the reaction vessel 16. Then, the pressure relief pipe 9 is connected to the gas treatment device, which can effectively prevent untreated harmful gases from diffusing into the air, causing harm to workers and polluting the environment. Then, the motor 18 is started. The motor 18 drives the mounting frame 19 to rotate, and the mounting frame 19 drives the stirring rod 20 to rotate, which can accelerate the flow of the reaction liquid inside the reaction vessel 16, thereby increasing the contact frequency between reactants and improving the reaction rate. The reaction liquid containing copper ions after the reaction can be discharged through the liquid outlet pipe 17 for subsequent treatment.

[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
