Description

Technical Field

[0001] This utility model discloses an integrated circuit board metal recycling device, which belongs to the field of waste circuit board recycling technology. Background Technology

[0002] With the development of information technology, a large number of electronic and electrical devices have emerged. Circuit boards, as an important component of electronic components, have experienced rapid growth and are being updated in large quantities. Since waste circuit boards contain metal materials such as copper, gold, and silver, which have high recycling value, they are usually recycled. During the recycling process, recycling equipment is usually used to screen and recover the metal powder after the waste circuit boards are crushed, which facilitates subsequent processing.

[0003] Chinese utility model patent CN221847886U discloses a waste circuit board metal powder recycling device, including a box body with a recycling chamber inside. Three sets of guide hoods are arranged horizontally side by side in the recycling chamber. A fan is fixedly installed on the box body, and an air duct is fixedly installed on the box body. The air outlet of the air duct is connected to the recycling chamber. A magnetic conveyor belt is installed in the recycling chamber and is located below the guide hood near the air duct. One end of the magnetic conveyor belt is located at the first set of discharge ports. A screening port is provided below the first set of discharge ports. A scraper is fixedly installed in the recycling chamber, with the top of the scraper abutting against the bottom of the magnetic conveyor belt. A conveyor plate is inclined in the recycling chamber, with the top of the conveyor plate located below the scraper.

[0004] This device utilizes the difference in density between metallic and non-metallic physical powders to screen them under gravity. However, due to the different sizes of the powders, lighter metallic particles and heavier non-metallic particles may be mistakenly screened under the same wind force, resulting in reduced recycling accuracy. Utility Model Content

[0005] In view of the above-mentioned shortcomings in the prior art, the present invention provides an integrated circuit board metal recycling device to solve the problems in the background art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An integrated circuit board metal recycling device includes a main body, a screening chamber inside the main body, a feed inlet communicating with the screening chamber fixedly disposed on the top of the main body, and an air duct communicating with the screening chamber fixedly disposed on the side of the main body.

[0008] The screening assembly is set inside the screening chamber and includes a fan, a metal mesh, a scraper, and a discharge port; the air outlet of the fan is connected to the air inlet of the air duct, three sets of discharge ports are fixedly set in the middle of the screening chamber, the metal mesh is fixedly set above the discharge port, and the scraper abuts against the metal mesh.

[0009] Furthermore, the discharge port includes discharge port one, discharge port two, and discharge port three, and a storage box is provided at the lower end of the discharge port.

[0010] Furthermore, a slide rail is provided through the back of the main body, a rack is fixedly provided on one side of the slide rail, the rack is fixedly connected to the main body, and the scraper is slidably connected to the slide rail.

[0011] Furthermore, one end of the scraper is fixedly connected to the motor, the output end of the motor is fixedly connected to the gear, and the gear meshes with the rack.

[0012] Furthermore, a protective shell is provided on the outer side of the slide rail.

[0013] Furthermore, an insulating frame is provided around the metal mesh, and a transformer rectifier is provided inside the main body to connect the metal mesh.

[0014] As described in the integrated circuit board metal recycling device, two sets of scrapers are symmetrically arranged on both sides of the metal mesh. The scrapers include a scraper blade and a guard plate. The scraper blade abuts against the metal mesh, and the guard plate is L-shaped and fixedly connected to the scraper blade.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] 1. By using the wind power of the fan for sorting and the electrostatic adsorption of the metal mesh, more efficient and precise recycling of metal and non-metal particles is achieved, improving the accuracy and efficiency of recycling.

[0017] 2. Through the combined action of discharge port one, discharge port three, and the metal mesh, lighter metal particles that escape from discharge port one can be recovered through the metal mesh to discharge port three, thus improving the accuracy of recovery.

[0018] 3. By scraping the metal mesh back and forth with a scraper blade, non-metallic particles adsorbed on the metal mesh are removed. At the same time, the guard plate prevents non-metallic particles from escaping to discharge port one or discharge port three during the scraping process, ensuring the passage of metal particles escaping from discharge port one through the metal mesh and improving the recycling efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Example 1:

[0032] like Figure 1-3 As shown, this utility model discloses an integrated circuit board metal recycling device. Specifically, it includes a main body 1, a screening chamber 2 is provided inside the main body 1, a feed inlet 3 communicating with the screening chamber 2 is fixedly provided on the top of the main body 1, and an air duct 4 communicating with the screening chamber 2 is fixedly provided on the side of the main body 1.

[0033] The screening assembly is located inside the screening chamber 2 and includes a fan 5, a metal mesh 6, a scraper 7, and a discharge port 8. The air outlet of the fan 5 is connected to the air inlet of the air duct 4. Three sets of discharge ports 8 are fixedly installed in the middle of the screening chamber 2. The metal mesh 6 is fixedly installed above the discharge ports 8, and the scraper 7 abuts against the metal mesh 6. The metal mesh 6 is positioned directly opposite the air duct 4. The metal mesh 6 can be made of stainless steel, tungsten copper alloy, or nickel-based alloy, possessing both electrical conductivity and mechanical strength.

[0034] The feeding port 8 includes feeding port one 801, feeding port two 802, and feeding port three 803. A storage box 9 is provided at the lower end of feeding port 8. The diameter of the storage box 9 is larger than the diameter of the lower end of feeding port 8 to facilitate the acceptance of screened particles. Feeding port one 801 receives heavy metal particles that settle due to gravity, feeding port three 803 receives light metal particles that pass through the metal mesh 6, and feeding port two 802 receives non-metallic particles adsorbed by the metal mesh 6.

[0035] A protective shell 14 is provided on the outside of the slide rail 10. This is to prevent uneven airflow in the screening chamber 2 due to gaps in the slide rail 10 and to prevent contamination by foreign particles.

[0036] like Figure 4 As shown, a slide rail 10 is installed through the back of the main body 1. A rack 11 is fixedly installed on one side of the slide rail 10 and is fixedly connected to the main body 1. A scraper 7 is slidably connected to the slide rail 10. One end of the scraper 7 is fixedly connected to the motor 12, and the output end of the motor 12 is fixedly connected to the gear 13. The gear 13 meshes with the rack 11. When needed, the motor 12 is started, causing the gear 13 to drive the scraper 7 to move along the rack 11 to scrape the particles on the metal mesh 6 to the discharge port 802.

[0037] like Figure 5As shown, an insulating frame 15 is provided around the metal mesh 6, and a transformer rectifier 16 is provided inside the main body 1 to connect to the metal mesh 6.

[0038] like Figure 6 As shown, two sets of scrapers 7 are symmetrically arranged on both sides of the metal mesh 6. The scrapers 7 include a scraper blade 701 and a guard plate 702. The blade of the scraper blade 701 abuts against the metal mesh 6, and the guard plate 702 is L-shaped and fixedly connected to the scraper blade 701. The guard plate prevents non-metallic particles from escaping to discharge port one or discharge port three during the scraping process, and ensures the passage of metal particles escaping from discharge port one.

[0039] The operating principle of the integrated circuit board metal recycling device disclosed in this application is as follows: During implementation, the fan 5 and the transformer rectifier 16 are started to energize the metal mesh 6. The crushed metal particles are fed into the feed inlet 3. Under the action of the wind, the heavier metal particles will fall into the discharge port 1 801. At the same time, non-metallic particles will be attracted to the metal mesh 6 due to electrostatic adsorption. The good conductivity of metal allows the lighter metal particles to pass through the metal mesh 6 and fall into the discharge port 3 803. The motor 12 is started to drive the gear 13 to drive the scraper 7 to move along the rack 11 to scrape the particles on the metal mesh 6 to the discharge port 2 802, thus completing the classification of metal and non-metal particles and realizing the recycling of metal from integrated circuit boards.
