Description

Technical Field

[0001] This utility model relates to the field of lead anode mud recycling technology, specifically an automatic scraping and collection device for lead anode mud based on the recycling of waste circuit boards. Background Technology

[0002] With the rapid development of the electronics industry, the recycling and disposal of waste printed circuit boards has become an important issue for resource recycling and environmental protection. In this process, processes such as electrolytic copper extraction produce lead-containing anode mud byproducts, which are rich in valuable metals such as lead and silver. However, if not handled properly, lead dust leakage will cause serious environmental pollution.

[0003] Currently, the collection of lead anode sludge mainly relies on manual operation, requiring workers to periodically stop the machine and manually scrape off the deposits on the anode surface of the electrolytic cell. This method is not only inefficient but also prone to lead dust dispersion due to improper operation, threatening personnel health. Furthermore, manual scraping makes complete recovery of lead anode sludge difficult, and some residues may redissolve in the electrolyte, affecting subsequent metal refining processes. Although some companies have attempted to use semi-automated equipment to assist collection, problems such as uneven scraping force, lead anode sludge scattering, and poor equipment adaptability still exist, making it difficult to meet the needs of large-scale industrial recycling.

[0004] According to the authorization announcement number CN 116465222 A, an automatic scraping and collecting device for lead anode mud based on waste circuit board recycling is disclosed, including a furnace body. A collar mechanism is fixedly installed on the top of the furnace body. The collar mechanism includes a support plate. An annular groove facing the inside of the furnace body is recessed on the bottom side of the support plate. A closing mechanism is installed on the bottom wall of the annular groove. A rotating motor is fixedly connected to the bottom wall of the annular groove on the side of the irregular sealing plate. A scraping ring is provided at the top of the annular groove near the irregular sealing plate. Limiting plates are symmetrically provided at the bottom of the scraping ring. A discharge port is provided at the bottom of the furnace body.

[0005] Existing automatic scraping and collection devices for lead anode mud scrape off excess waste material from circuit boards during the scraping process. If these mixed materials are collected and stored directly, the purity of the lead anode mud will decrease, which will seriously affect its final quality. Therefore, there is a need for an automatic scraping and collection device for lead anode mud based on the recycling of waste circuit boards. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic scraping and collection device for lead anode mud based on the recycling of waste circuit boards. The device uses a vibrating motor to drive a screen to vibrate and screen the mixed material scraped off the circuit boards, thereby solving the technical problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic scraping and collecting device for lead anode mud based on the recycling of waste circuit boards, comprising a box, wherein a scraping component for scraping lead anode mud is installed inside the box, and a fixing component for fixing the circuit board is installed on the side of the scraping component inside the box.

[0008] The scraping assembly has a guide block installed at its lower part. The guide block has a through hole in its middle. A fixing frame is installed in the middle of the through hole. A vibration motor is embedded in the side of the fixing frame inside the guide block. A screen is installed in the middle of the fixing frame. A heating plate is embedded in the outer side of the screen inside the fixing frame.

[0009] Preferably, the scraping assembly includes an electric push rod installed on the top of the housing, and the output end of the electric push rod is fitted with a U-shaped frame through the top of the housing.

[0010] Preferably, a motor is installed on one side of the U-shaped frame, and a rotating shaft is installed through the side of the U-shaped frame at the output end of the motor. A scraping roller is installed on the outer arc surface of the rotating shaft at the middle of the U-shaped frame.

[0011] Preferably, a water tank is installed on the top of the box body, located on the side of the electric push rod, and a miniature water pump is embedded in the bottom of the water tank, located on the top of the box body.

[0012] Preferably, a water storage box is installed on the side of the U-shaped frame, the output end of the micro water pump is connected to the top of the water storage box through a hose, and several sets of micro atomizing nozzles are installed at the bottom of the water storage box.

[0013] Preferably, the fixing component includes a fixing block installed on the inner wall of the box, and a fixing plate is installed on the side of the fixing block corresponding to the scraping roller.

[0014] Preferably, a number of rubber suction cups are installed through the middle of the fixing plate, and an air pump is installed through the input end of the number of rubber suction cups through the side of the box. The air pump is located on the outside of the box.

[0015] Preferably, a conveying pipe is installed at the bottom of the guide block, and a collection box is installed on the lower surface of the box body at the output end of the conveying pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The waste circuit boards to be processed are fixed to the fixing assembly. The scraping assembly is then activated to scrape the surface of the circuit boards, causing the lead anode sludge and mixed waste to fall off. The scraped mixture then falls onto the screen in the middle of the guide block. At this time, the heating plate starts working, drying the mixture through the screen to remove moisture and volatile impurities. Subsequently, the vibration motor is activated, causing the fixing frame and screen to vibrate. Under the combined action of vibration screening and heating drying, fine particles of lead anode sludge pass through the screen and fall into the lower collection device, effectively improving the separation efficiency and product purity of the lead anode sludge, thereby ensuring the final recycling quality.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides: an automatic scraping and collection device for lead anode mud based on the recycling of waste circuit boards, such as... Figures 1-5As shown, the device includes a housing 1. Inside the housing 1, a scraping assembly 2 for scraping lead anode mud is installed. On the side of the scraping assembly 2, inside the housing 1, a fixing assembly 3 for fixing the circuit board is installed. The scraping assembly 2 is specifically used for scraping lead anode mud, and the fixing assembly 3 can stably fix the circuit board so that the circuit board will not shake or shift when the scraping assembly 2 is working. This ensures that the scraping action can be accurately applied to the target position, improves scraping efficiency and quality, and reduces problems such as incomplete scraping or scratching of the circuit board caused by circuit board instability.

[0026] A guide block 4 is installed at the lower part of the scraping component 2. A through hole 5 is opened in the middle of the guide block 4. A fixing frame 6 is installed in the middle of the through hole 5. A vibration motor 7 is embedded in the side of the fixing frame 6 inside the guide block 4. A screen 8 is installed in the middle of the fixing frame 6. A heating plate 9 is embedded in the outer side of the screen 8 inside the fixing frame 6. The guide block 4 is installed at the lower part of the scraping component 2 and can guide the scraped lead anode mud to a specific direction. The through hole 5 provides a downward flow channel for the lead anode mud, so that the material can pass smoothly through the guide block 4 to the screen 8 for screening. The fixing frame 6 is installed in the middle of the through hole 5, which serves to support the screen 8, the vibrating motor 7 and the heating plate 9. When the vibrating motor 7 is working, it will cause the screen 8 to vibrate. This vibration can accelerate the movement speed of the lead anode mud on the screen 8, prevent the material from accumulating on the screen, and enable the material to pass through the screen more quickly and evenly, separating large particles of impurities and waste residue from the lead anode mud, thereby improving the purity of the lead anode mud. The heating plate 9 can heat the lead anode mud, causing the moisture to evaporate and reducing the water content of the lead anode mud.

[0027] The vibration motor 7 uses a YZU-10-4 model vibration motor with a vibration intensity of 0.25kW, which can effectively prevent material from clogging the screen. The vibration frequency of 1500 times / minute is more suitable for separating wet and sticky materials, reducing dust. With an IP55 protection rating, it is suitable for working in humid environments.

[0028] Screen 8 is made of 316L stainless steel with a mesh count of 200 and an aperture of 0.075mm. It can effectively separate lead anode mud from large particles of waste. 316L stainless steel has strong corrosion resistance and will not rust even after long-term contact with lead mud. At the same time, the thickened frame design can resist long-term impact from vibration motors.

[0029] Heating plate 9 uses SRY6-380V / 3KW stainless steel heating plate, which has high heat conduction efficiency, allowing lead anode mud to dry quickly. The stainless steel material is more corrosion resistant and has adjustable temperature control (50-200℃) to avoid high temperature damage to the screen or lead mud composition.

[0030] Preferably, the scraping assembly 2 includes an electric push rod 21 installed on the top of the housing 1. The output end of the electric push rod 21 passes through the top of the housing 1 and is equipped with a U-shaped frame 22. The electric push rod 21 can precisely control the lifting height of the U-shaped frame 22, ensuring that the scraping roller 24 can effectively scrape the lead anode mud without damaging the circuit board or the scraping assembly due to excessive pressure.

[0031] The electric actuator 21 uses the LA42-500N model, whose 500N thrust is sufficient to stably support the scraping component and prevent shaking during scraping. The 400mm stroke is suitable for circuit boards of different thicknesses, and the 10mm / s speed balances efficiency and accuracy. It has a built-in limit switch to prevent overload damage to the circuit board.

[0032] Furthermore, a motor 23 is installed on one side of the U-shaped frame 22. A rotating shaft is installed through the output end of the motor 23 on the side of the U-shaped frame 22. A scraping roller 24 is installed in the middle of the U-shaped frame 22 via the outer arc surface of the rotating shaft. The motor 23 provides stable and powerful power to the scraping roller 24. Stable power output ensures that the scraping roller 24 rotates at a uniform speed, making the scraping process continuous and stable, avoiding incomplete scraping due to insufficient or unstable power, and efficiently scraping the lead anode mud off the circuit board.

[0033] Motor 23 uses a 57HS22 stepper motor. The stepper motor can precisely control the speed of the scraping roller to avoid damage to the circuit board surface due to excessive speed. The high torque (1.2Nm) ensures stable load when scraping lead mud and prevents jamming. The enclosed design can effectively prevent dust and adapt to lead dust environment.

[0034] Furthermore, a water tank 25 is installed on the top of the housing 1, located on the side of the electric push rod 21. A micro water pump 26 is embedded at the bottom of the water tank 25. During the scraping of lead anode mud, some mud may remain on the circuit board or equipment. By pumping water from the water tank 25 through the micro water pump 26, these parts can be rinsed, keeping the equipment clean and helping to improve the operating efficiency and service life of the equipment.

[0035] The miniature water pump 26 uses the DC12V WKY-15 model, with a flow rate of 2L / min to meet the requirements of the atomizing nozzle, a head of 3m to ensure stable water pressure, and a corrosion-resistant pump body that is more suitable for long-term contact with lead-containing water.

[0036] It is worth noting that a water storage box 27 is installed on the side of the U-shaped frame 22. The output end of the micro water pump 26 is connected to the top of the water storage box 27 through a hose 28. Several sets of micro atomizing nozzles 29 are installed at the bottom of the water storage box 27. During the scraping of lead anode mud, a large amount of dust is generated. The micro atomizing nozzles 29 can atomize the water in the water storage box 27 into tiny water droplets. These water droplets can combine with the dust in the air, increasing their weight and causing them to settle, thereby effectively reducing the dust concentration in the air. At the same time, the sprayed water mist can reduce the friction during the scraping process, allowing the scraping roller 24 to roll more smoothly on the circuit board surface, reducing damage to the circuit board, and also helping to improve scraping efficiency, making it easier to scrape off the lead anode mud. The hose 28 connects the micro water pump 26 and the water storage box 27, allowing the water storage box 27 to move with the lifting and lowering of the U-shaped frame 22, ensuring a stable water source for the micro atomizing nozzles 29 at different working heights and positions.

[0037] Specifically, the fixing component 3 includes a fixing block 31 installed on the inner wall of the housing 1. A fixing plate 32 is installed on the side of the fixing block 31 corresponding to the scraping roller 24. The fixing block 31 is installed on the inner wall of the housing 1, providing a stable support base for the fixing plate 32. The fixing plate 32 can position the scraping roller 24, so that the scraping roller 24 can better fit the surface of the circuit board for scraping.

[0038] More specifically, several sets of rubber suction cups 33 are installed through the middle of the fixing plate 32. The input ends of the rubber suction cups 33 are installed through the side of the box 1 and a vacuum pump 34 is installed. The vacuum pump 34 is located on the outside of the box 1. Under the action of the vacuum pump 34, the rubber suction cups 33 can generate a strong suction force, which tightly adheres to the circuit board and firmly fixes the circuit board in the designated position. This prevents the circuit board from moving or shaking under the pressure and friction of the scraping roller 24, thereby improving the accuracy and consistency of scraping and ensuring that the lead anode mud can be scraped off completely and efficiently.

[0039] The vacuum pump 34 uses a 2XZ-2 rotary vane vacuum pump with a pumping speed of 2L / s, which can quickly provide negative pressure to the rubber suction cup 33, ensuring that the circuit board is fixed without deviation. The high vacuum of -0.098MPa ensures firm adsorption, and it can be stably fixed even if the surface of the circuit board is uneven.

[0040] Preferably, a conveying pipe 10 is installed at the bottom of the guide block 4, and a collection box 11 is installed on the lower surface inside the box 1 at the output end of the conveying pipe 10. After screening, the lead anode mud in the guide block 4 can be smoothly conveyed to the collection box 11 located on the lower surface inside the box 1 through the conveying pipe 10, which facilitates the subsequent unified processing of the material.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
