Description

Technical Field

[0001] This utility model relates to the technical field of carbon treatment recycling devices, specifically a carbon treatment fine filtration adsorption regeneration recycling device. Background Technology

[0002] Electroplating copper / nickel is a process (a special process) in the production of printed circuit boards (PCBs / FPCs) that involves a large number of chemical solutions (copper sulfate / nickel, brighteners, leveling agents, wetting agents, etc.).

[0003] The PCB electroplating process (copper / nickel) requires the use of copper / nickel sulfate and organic additives (brighteners, leveling agents, etc.), resulting in wastewater containing heavy metal ions and recalcitrant organic matter. Traditional activated carbon treatment suffers from rapid adsorption saturation. Patent document CN213995074U proposes an easily replaceable high-efficiency carbon filter cartridge for carbon treatment, comprising a treatment chamber. A filter box is fixedly installed inside the treatment chamber, and a filter plate is installed inside the filter box. A sealing cover is fixedly installed at the top of the treatment chamber, and two limiting clamps are installed on the upper surface of the sealing cover. A carbon treatment liquid injection pipe is provided on one side of the treatment chamber. A connecting guide rod is slidably connected to the inside of the sealing cover. A connector is installed on the inner side of the bottom end of the connecting guide rod, and two filtration mechanisms are installed on the outer side of the bottom end of the connecting guide rod. Each filtration mechanism includes a filter cartridge frame, a filter cartridge body, and separators. Six separators are evenly installed on the inner side of the filter cartridge frame, and two filter cartridge bodies are installed on one side of each separator. This invention enables rapid filtration of electroplating chemicals, facilitating filter replacement and protection, and provides excellent sealing to prevent chemical leakage.

[0004] However, there are certain drawbacks. Frequent replacement of filter elements may increase the complexity of the equipment and maintenance costs. There may also be limitations on the adaptability and compatibility with different types of electroplating solutions. To address these issues, we propose a carbon treatment fine filtration adsorption regeneration circulation device. Utility Model Content

[0005] One of the technical problems this application aims to solve is that frequent filter replacement may increase the complexity of the equipment and maintenance costs, and there may be limitations on the adaptability and compatibility with different types of electroplating solutions.

[0006] To solve the above-mentioned technical problems, this application provides a carbon treatment fine filtration adsorption regeneration circulation device, including a first treatment box and a second treatment box. A centrifugal screen is rotatably connected to one end of the inner cavity of the first treatment box, and an outlet pipe is fixedly connected to one end of the inner cavity of the centrifugal screen. A fixing plate is provided inside the second treatment box, and a precision fiber filter layer, an adsorption layer and an activated carbon layer are arranged sequentially outward from the middle of the fixing plate.

[0007] In some embodiments, a slot is provided at one end of the centrifugal screen, and the centrifugal screen is rotatably connected to one end of the inner cavity of the first processing box through the slot. A motor is provided at one end of the first processing box, and the output end of the motor is fixedly connected to one end of the centrifugal screen.

[0008] In some embodiments, the surface of the liquid outlet pipe is uniformly provided with a plurality of liquid outlet holes, one end of the liquid outlet pipe extends upward to a liquid injection pipe, the liquid injection pipe and the liquid outlet pipe are rotatably connected, and one end of the liquid injection pipe is fixedly connected to the top of the first processing tank.

[0009] In some embodiments, a partition plate is provided between the first processing tank and the second processing tank. A water pump is provided on the surface of the partition plate. A liquid distribution pipe is fixedly connected around the water pump. A suction head is fixedly connected to the surface of the water pump through a pipe. The suction head is located at the bottom of the inner cavity of the first processing tank.

[0010] In some embodiments, the separator plate has a plurality of first connection holes on its surface, the first connection holes are arranged in an array, and the first connection holes are interconnected with the liquid distribution tube.

[0011] In some embodiments, an external fixing frame is provided on the outside of the second processing box, and an air inlet pipe is provided at intervals on the inner wall of the external fixing frame. A second connecting hole corresponding to the air inlet pipe is opened on the surface of the second processing box, and the air inlet pipe and the second connecting hole are interconnected.

[0012] In some embodiments, the surface of the second processing box is provided with a cleaning groove, and one end of the bottom of the outer fixing frame is provided with a discharge port.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. This utility model achieves step-by-step adsorption of pollutants by setting up a multi-stage gradient filtration structure. The water pump delivers the electroplating solution to multiple chambers formed by the fixed plate through the liquid distribution pipe. The activated carbon layer has a strong adsorption capacity due to its porous structure, which can effectively remove suspended solids, impurities and some harmful substances in the electroplating solution, playing a preliminary purification role. The adsorption layer has high selectivity and adsorption capacity, which can perform deep purification on specific ions or molecules in the electroplating solution. Different types of resins can be selected for different pollutants to improve purification efficiency. The precision fiber filter layer has a small filtration pore size, which can further remove tiny particles and residues in the electroplating solution, protect the subsequent processing equipment from contamination, and purify different types of electroplating solutions, thereby improving the recycling rate of the electroplating solution.

[0016] 2. This utility model uses a motor to drive the centrifugal screen to rotate. When the electroplating solution enters the interior of the outlet pipe through the injection pipe, it enters the inner cavity of the centrifugal screen through the outlet hole. The centrifugal force generated when the centrifugal screen rotates traps large solid particles of impurities in the electroplating solution on the surface of the centrifugal screen, thereby improving the filtration efficiency of the electroplating solution in the subsequent fine filtration process.

[0025] 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.

[0026] Example 1: Please refer to Figure 1-6 This utility model provides a technical solution: a carbon treatment fine filtration adsorption regeneration circulation device, including a first treatment box 1 and a second treatment box 2. A centrifugal screen 4 is rotatably connected to one end of the inner cavity of the first treatment box 1, and an outlet pipe 5 is fixedly connected to one end of the inner cavity of the centrifugal screen 4. A fixing plate 6 is provided inside the second treatment box 2. A precision fiber filter layer 602, an adsorption layer 601, and an activated carbon layer 600 are arranged sequentially outward from the middle of the fixing plate 6. The activated carbon layer 600, the adsorption layer 601, and the precision fiber filter layer 602 are separated into multiple chambers by the fixing plate 6. The activated carbon layer 600 has a strong adsorption capacity due to its porous structure, which can effectively remove suspended solids, impurities, and some harmful substances in the electroplating solution, playing a preliminary purification role. The adsorption layer 601 has high selectivity and adsorption capacity, and can perform deep purification on specific ions or molecules in the electroplating solution. Different types of resins can be selected to target different pollutants, thereby improving purification efficiency. The precision fiber filter layer 602 has a fine filtration pore size, which can further remove tiny particles and residues in the electroplating solution, protect subsequent processing equipment from contamination, and purify different types of electroplating solutions, thereby improving the recycling rate of the electroplating solution.

[0027] Please see Figure 2-4One end of the centrifugal screen 4 is provided with a slot 400. The centrifugal screen 4 is rotatably connected to one end of the inner cavity of the first processing box 1 through the slot 400. One end of the first processing box 1 is provided with a motor 10. The output end of the motor 10 is fixedly connected to one end of the centrifugal screen 4. Multiple outlet holes 500 are evenly provided on the surface of the outlet pipe 5. One end of the outlet pipe 5 extends upward to the injection pipe 3. The injection pipe 3 and the outlet pipe 5 are rotatably connected. One end of the injection pipe 3 is fixedly connected to the top of the first processing box 1. The motor 10 drives the centrifugal screen 4 and the outlet pipe 5 fixedly connected to the inside to rotate. As the injection pipe 3 delivers electroplating solution into the outlet pipe 5, the centrifugal force generated when the outlet pipe 5 rotates will initially filter large particulate impurities in the electroplating solution through the centrifugal screen 4, thereby improving the purification efficiency of the subsequent electroplating solution.

[0028] Please see Figure 2-3 A partition plate 100 is provided between the first processing tank 1 and the second processing tank 2. A water pump 8 is provided on the surface of the partition plate 100. A liquid distribution pipe 9 is fixedly connected around the water pump 8. A suction head 7 is fixedly connected to the surface of the water pump 8 through a pipe. The suction head 7 is located at the bottom of the inner cavity of the first processing tank 1. The partition plate 100 has multiple first connection holes 101 on its surface. The first connection holes 101 are arranged in an array and are interconnected with the liquid distribution pipe 9. The water pump 8 draws the pre-filtered electroplating solution from the bottom of the inner cavity of the first processing tank 1 through the suction head 7 connected by the pipe. The water pump 8 generates centrifugal force through the high-speed rotating impeller, so that the liquid drawn by the suction head 7 gains kinetic and pressure energy. Then, the liquid is transported through the liquid distribution pipe 9 around the water pump 8 to multiple chambers separated by a fixed plate 6 through the first connection holes 101.

[0029] Please see Figure 5-6 The second processing box 2 is provided with an external fixing frame 14. The inner wall of the external fixing frame 14 is provided with air inlet pipes 15 at intervals. The surface of the second processing box 2 is provided with a second connection hole 200 corresponding to the air inlet pipe 15. The air inlet pipe 15 and the second connection hole 200 are interconnected. The air inlet pipe 15 is used to pressurize the electroplating solution delivered to the chamber through the first connection hole 101. Under the gas pressure, the electroplating solution passes through the activated carbon layer 600, the adsorption layer 601 and the precision fiber filter layer 602 in sequence. Then, it is drawn out of the interior of the second processing box 2 by an external pump connected to one end of the output pipe 13 for recycling.

[0030] Please see Figure 2-6The surface of the second processing box 2 is provided with a removal groove 201. A discharge port 17 is provided at one end of the bottom of the outer fixing frame 14. A sealing door 16 is provided at the connection between the discharge port 17 and the removal groove 201. One end of the sealing door 16 is attached to the periphery of the second processing box 2. A support frame 12 is provided at one end of the second processing box 2. A conductive slip ring 11 is movably connected to one end of the support frame 12. The conductive slip ring 11 is fixedly connected to one end of the fixing plate 6. An output pipe 13 is provided through the interior of the conductive slip ring 11. The inner cavity of the fixing plate 6 and the output pipe 13 are interconnected. Since impurity particles may still exist on the surface of the activated carbon layer 600 after secondary filtration, the connection between the removal groove 201 and the discharge port 17 can remove impurity particles from the external chamber. The particles are cleaned, and the closed door 16 is slidably connected to the side of the second processing box 2 via an electric slide rail. The connection between the closed door 16 and the second processing box 2 is provided with a sealing structure to seal the connection between the inner cavity of the second processing box 2 and the discharge port 17, so as to prevent leakage during the operation of the device. Since the side of the partition plate 100 in the inner cavity of the second processing box 2 is provided with a protrusion for connecting the fixing plate 6, the other end of the fixing plate 6 can be fixedly connected to the outside of the conductive slip ring 11. Since the conductive slip ring 11 uses sliding contact conduction and relative motion isolation to make the fixing plate 6 rotate with the conductive slip ring 11, the rotation can accelerate the filtration efficiency of the electroplating solution under the gas pressure generated by the air inlet pipe 15.

[0031] Example 2: Please refer to Figure 7 This utility model provides a technical solution: a carbon treatment fine filtration adsorption regeneration circulation device, including an outer fixed frame 14, a buffer plate 18 fixedly connected to the bottom of the inner cavity of the outer fixed frame 14, and shock-absorbing springs 19 arranged in an array on the top of the buffer plate 18. Since the impurity removal groove 201 opened at the bottom of the second treatment box 2 is interconnected with the discharge port 17, when the fixed plate 6 set inside the second treatment box 2 rotates under the drive of the conductive slip ring 11, vibration will be generated. Since the impurity removal groove 201 is interconnected with the discharge port 17, the generated vibration will be transmitted to the outer fixed frame 14. The top of the shock-absorbing springs 19 set at the bottom of the inner cavity of the outer fixed frame 14 is connected to the surface of the second treatment box 2 to perform shock absorption on the second treatment box 2, thereby significantly improving the performance of the device and extending its service life by reducing the mechanical stress borne by the device during operation.
