Description

Technical Field

[0001] This invention relates to the technical field of wastewater treatment, and more particularly to a wastewater treatment device for circuit board browning. Background Technology

[0002] In the circuit board manufacturing process, the browning process is a key step to enhance the interlayer bonding of multilayer boards. However, it generates wastewater with high concentrations of heavy metals, including copper ions, complexing agents, and additives. Direct discharge of this wastewater will cause serious environmental pollution and must be properly treated and recycled.

[0003] Currently, a combined chemical precipitation-electrolysis process is commonly used for copper ion treatment: first, precipitants such as sodium sulfide or calcium hydroxide are added to form copper sulfide or copper hydroxide precipitates; then, sulfuric acid is used to dissolve the precipitate, obtaining a high-concentration copper-containing solution; finally, this solution is pumped into an electrolytic cell for electrolytic recovery. During electrolysis, a copper ion reduction reaction occurs at the cathode to precipitate metallic copper, while an oxidation reaction occurs at the anode to generate insoluble compounds such as copper oxide and cuprous oxide, forming fine-particle anode sludge. This anode sludge exists in dispersed powder form and easily adheres to the surface of the anode plate and the inner wall of the electrolytic cell. It accumulates continuously as electrolysis progresses, requiring periodic shutdowns for manual cleaning, which not only increases labor costs but also disrupts production continuity, severely impacting processing efficiency and system stability. Summary of the Invention

[0004] In view of this, the present invention provides a circuit board browning wastewater treatment device, which can overcome the disadvantages of the cumbersome operation of manually cleaning the anode plate surface and the inner wall of the electrolytic cell, and the need to interrupt the electrolysis process, resulting in reduced treatment efficiency.

[0005] The technical solution is as follows: a circuit board browning wastewater treatment device, comprising: a support frame; a sedimentation tank connected to the support frame; an electrolytic cell connected to the support frame; a control panel installed on the top of the electrolytic cell; a discharge frame connected to the side of the electrolytic cell and maintaining communication; a first drive motor installed on the side of the electrolytic cell; a rotating frame rotatably connected to the inside of the electrolytic cell, with the end of the rotating shaft of the rotating frame connected to the output shaft of the first drive motor; cathode plates symmetrically spaced on the rotating frame; anode plates symmetrically spaced on the rotating frame; filter cloth symmetrically spaced on the rotating frame; a fixing assembly installed on the rotating frame for fixing the cathode plates and anode plates; a cleaning assembly installed on the top of the electrolytic cell for cleaning the surfaces of the cathode plates and anode plates; and a discharge assembly installed on the support frame for discharging materials from the sedimentation tank and the electrolytic cell.

[0006] As an improvement to the above solution, the fixing component includes: spring clips, which are symmetrically spaced on the rotating frame, and the rotating frame has symmetrically spaced first circular holes; and insert rods, which are symmetrically connected to the sides of the cathode plate and the anode plate, respectively, and the insert rods are inserted into the first circular holes, and the cathode plate and the anode plate have symmetrically spaced second circular holes on both sides, and the spring clips are locked in the second circular holes.

[0007] As an improvement to the above solution, the cleaning component includes: a fixed frame, symmetrically connected to the top of the electrolytic cell; a slider, slidably connected to the fixed frame; a lead screw motor, mounted on the fixed frame, with the lead screw of the lead screw motor threadedly connected to the slider; a first electric push rod, mounted on the slider; a lifting frame, connected to the telescopic rod of the first electric push rod; sponge plates, symmetrically spaced and connected to the lifting frame; and a baffle mechanism, located inside the electrolytic cell, used to block the side of the discharge frame.

[0008] As an improvement to the above solution, the material blocking mechanism includes: an electric drum installed inside the electrolytic cell; and a material blocking frame installed on the electric drum.

[0009] As an improvement to the above solution, the discharge assembly includes: a first mud pump, mounted on a support frame; connecting pipes, one end of which is connected to the inlet and outlet of the first mud pump respectively and kept in communication, and the other end of which is connected to the bottom of the sedimentation tank and the electrolysis tank respectively and kept in communication; a second mud pump, mounted on the support frame; a suction pipe, both ends of which are connected to the bottom of the electrolysis tank and the inlet of the second mud pump respectively and kept in communication; and a feeding pipe, connected to the outlet of the second mud pump and kept in communication.

[0010] As an improvement to the above solution, the following are also included: a water pump installed on the side of the support frame; a water pumping pipe with both ends connected to the side of the sedimentation tank and the water pump inlet respectively and kept in communication; a hose connected to the water pump outlet and kept in communication; a diversion pipe connected inside the lifting frame, with the end of the hose away from the water pump connected to the diversion pipe and kept in communication; and nozzles connected at intervals to the bottom of the lifting frame, with the diversion pipe connected to the nozzles and kept in communication.

[0011] As an improvement to the above solution, it also includes: a cover plate placed inside the sedimentation tank; a second electric push rod symmetrically installed on the top of the cover plate; and an arc-shaped filter plate connected to the telescopic rod of the second electric push rod, with the arc-shaped filter plate located inside the sedimentation tank.

[0012] As an improvement to the above solution, it also includes: a second drive motor, installed on the side of the sedimentation tank; and a stirring frame, rotatably connected to the inside of the sedimentation tank, with the end of the rotating shaft of the stirring frame connected to the output shaft of the second drive motor.

[0013] Beneficial effects: 1. The present invention can realize the automatic cleaning of anode mud during electrolysis by the coordinated operation of the rotating frame, the first drive motor, the cleaning component and the baffle mechanism. The rotating frame rotates periodically, so that the cathode plate and the anode plate alternately enter the electrolyte or the cleaning station. The sponge plate scrapes off the attached material under the drive of the lifting frame. The baffle guides the cleaned material out. There is no need to stop the machine for manual cleaning, which can significantly improve the continuity of production and processing efficiency.

[0014] 2. The filter cloth of the present invention can rotate synchronously with the rotating frame. With the flushing assembly consisting of a water pump, a diversion pipe and a nozzle, the clogged filter cloth can be flushed with high-pressure water at the cleaning station to ensure the permeability of the filter cloth. At the same time, the arc-shaped filter plate in the sedimentation tank is driven to move up and down reciprocally by the second electric push rod. The hydraulic backwashing automatically removes the blockage of the filter holes. The dual filtration design effectively prevents the sediment from entering the drainage system and ensures the stability of wastewater treatment.

[0015] 3. The cathode plate and anode plate of the present invention are fixed to the rotating frame by the insertion rod and the spring clip, which allows for quick replacement of electrodes during disassembly. The separable design of the cover plate and the sedimentation tank, combined with the rotation of the stirring frame, facilitates the addition and mixing of the precipitant. At the same time, the intermittent operation of the stirring frame promotes uniform reaction and avoids sediment caking. This modular structure greatly reduces the difficulty of equipment maintenance and labor costs. Attached Figure Description

Detailed Implementation

[0029] Example: A circuit board browning wastewater treatment device, such as... Figures 1-9As shown, the system includes a support frame 1, a sedimentation tank 2, an electrolytic cell 3, a control panel 4, a discharge frame 5, a first drive motor 6, a rotating frame 7, a cathode plate 8, an anode plate 9, a filter cloth 10, a fixing assembly, a cleaning assembly, and a discharge assembly. The front half of the support frame 1 is stepped. The sedimentation tank 2 is connected to the left rear of the support frame 1. An inlet pipe is connected to the upper left side of the sedimentation tank 2 and remains connected. A discharge pipe is connected to the upper rear side of the sedimentation tank 2 and remains connected. The electrolytic cell 3 is connected to the right rear of the support frame 1. The control panel 4 is installed between the top front side of the sedimentation tank 2 and the top front side of the electrolytic cell 3. The discharge frame 5 is connected to the middle rear side of the electrolytic cell 3 and remains connected. The discharge frame 5 is inclined. The first drive motor is installed in the middle right side of the electrolytic cell 3. The electrolytic cell 3 is rotatably connected to a rotating frame 7 in the middle of the machine 6. The rotating frame 7 is in contact with the inner wall of the electrolytic cell 3, and the right end of the rotating shaft of the rotating frame 7 is connected to the output shaft of the first drive motor 6. Two sets of cathode plates 8 and two sets of anode plates 9 are symmetrically connected on the rotating frame 7, and the two sets of cathode plates 8 and two sets of anode plates 9 are arranged circumferentially. Four sets of filter cloths 10 are symmetrically connected on the rotating frame 7, and the filter cloths 10 are located between adjacent cathode plates 8 and anode plates 9. The rotating frame 7 is provided with a fixing component for fixing the cathode plates 8 and anode plates 9. The top of the electrolytic cell 3 is provided with a cleaning component for cleaning the surface of the cathode plates 8 and anode plates 9. The support frame 1 is provided with a discharge component for discharging the material inside the sedimentation tank 2 and the electrolytic cell 3.

[0030] like Figure 3 and Figure 4 As shown, the fixing assembly includes spring clips 11 and insert rods 13. Four sets of spring clips 11 are symmetrically spaced on the rotating frame 7. The four sets of spring clips 11 correspond to two sets of cathode plates 8 and two sets of anode plates 9, respectively. Four sets of first circular holes 12 are symmetrically spaced on the rotating frame 7. Two insert rods 13 are connected to the side of each cathode plate 8 and anode plate 9. The insert rods 13 can be inserted into the first circular holes 12. Second circular holes 14 are opened on both sides of each cathode plate 8 and anode plate 9. The clips of the spring clips 11 can be locked in the second circular holes 14.

[0031] like Figures 5-8As shown, the cleaning assembly includes a fixed frame 15, a slider 16, a lead screw motor 17, a first electric push rod 18, a lifting frame 19, a sponge plate 20, and a baffle mechanism. Fixed frames 15 are connected to the left and right sides of the top of the electrolytic cell 3. Slider 16 is slidably connected to the upper part of each fixed frame 15. A lead screw motor 17 is installed on the upper part of each fixed frame 15, and the lead screw of the lead screw motor 17 is threadedly connected to the slider 16. A first electric push rod 18 is installed on each slider 16. A lifting frame 19 is connected between the telescopic rods of the two first electric push rods 18. Multiple sponge plates 20 are spaced apart from left to right on both the front and rear sides of the lifting frame 19. The electrolytic cell 3 has a baffle mechanism inside to block the side of the discharge frame 5. The baffle mechanism includes an electric roller 21 and a baffle frame 22. An electric roller 21 is installed in the middle of the rear side inside the electrolytic cell 3, and a baffle frame 22 is installed on the electric roller 21, blocking the front side of the discharge frame 5.

[0032] like Figure 9 As shown, the discharge assembly includes a first mud pump 23, a connecting pipe 24, a second mud pump 25, a suction pipe 26, and a feeding pipe 27. The first mud pump 23 is installed on the lower left side of the support frame 1. The inlet of the first mud pump 23 is connected to the bottom of the sedimentation tank 2 by the connecting pipe 24 and is kept in communication. The outlet of the first mud pump 23 is also connected to the bottom of the electrolytic cell 3 by the connecting pipe 24 and is kept in communication. The second mud pump 25 is installed on the lower right side of the support frame 1. The inlet of the second mud pump 25 is connected to the bottom of the electrolytic cell 3 by the suction pipe 26 and is kept in communication. The outlet of the second mud pump 25 is connected to the feeding pipe 27 and is kept in communication.

[0033] When wastewater treatment is required, firstly, an appropriate amount of chemical precipitant is placed in sedimentation tank 2, and then an appropriate amount of sulfuric acid is placed in electrolytic cell 3, immersing the lower cathode plate 8 and anode plate 9 in the sulfuric acid. Then, wastewater is injected into sedimentation tank 2 through the inlet pipe. The chemical precipitant mixes with the wastewater, causing sedimentation in sedimentation tank 2. The liquid level in sedimentation tank 2 gradually rises. When the liquid level in sedimentation tank 2 is higher than the drain pipe, the clear water in sedimentation tank 2 is discharged through the drain pipe. Simultaneously, the first mud pump 23 can be started via control panel 4. The first mud pump 23, through connecting pipe 24, transports the precipitate from sedimentation tank 2 to electrolytic cell 3. The sulfuric acid dissolves the precipitate in electrolytic cell 3, obtaining a high concentration of... A copper solution is then electrolyzed through the lower cathode plate 8 and anode plate 9 to achieve a high concentration of copper. Metallic copper adheres to the surface of the lower cathode plate 8, while anode mud adheres to the surface of the lower anode plate 9 and the bottom of the electrolytic cell 3. The second mud pump 25 is then activated via the control panel 4. This second mud pump 25 extracts most of the anode mud from the electrolytic cell 3 through the extraction pipe 26 and discharges it through the feeding pipe 27. When cleaning the electrolytic cell 3, cathode plate 8, and anode plate 9 is required, the first drive motor 6 drives the rotating frame 7 to rotate 90 degrees. The rotating frame 7 scrapes the lower inner wall of the electrolytic cell 3 to remove the anode mud adhering to the inner wall. Simultaneously, the rotating frame 7 drives... The cathode plate 8, anode plate 9, and filter cloth 10 rotate 90 degrees, allowing the upper and lower cathode plates 8 to be swapped. Specifically, the cathode plate 8 with copper adhering to its surface rotates to the upper rear side of the rotating frame 7, while the other set of cathode plates 8 enters the high-concentration copper-containing solution for electrolysis. Since the rotating frame 7 is in contact with the inner wall of the electrolytic cell 3, its rotation causes the anode mud and high-concentration copper-containing solution within the electrolytic cell 3 to rotate as well. Because the baffle 22 blocks the front of the discharge frame 5, the high-concentration copper-containing solution is not discharged through the discharge frame 5, allowing sufficient time for the solution to pass through the filter cloth 10 and fall back into the electrolytic cell 3. The anode mud remains on the filter cloth 10. Then, the first electric push rod 1 is controlled by the control panel 4. The lifting frame 19 and the sponge plate 20 are driven to move downwards, so that the lifting frame 19 can descend to the upper rear side of the rotating frame 7, and the sponge plate 20 will contact the surface of the cathode plate 8 and the surface of the filter cloth 10. Then the control panel 4 will control the screw motor 17 to drive the slider 16 to move backwards. The slider 16 can drive the first electric push rod 18, the lifting frame 19 and the sponge plate 20 to move backwards. The sponge plate 20 can scrape the metal copper on the surface of the cathode plate 8 and the anode mud on the surface of the filter cloth 10 backwards. At the same time, the control panel 4 will control the electric roller 21 to drive the baffle 22 to rotate. When the metal copper and anode mud contact the baffle 22, the baffle 22 can transport the metal copper and anode mud backwards to the front end of the discharge frame 5, so that the metal copper and anode mud can be discharged backwards through the discharge frame 5.When the sponge plate 20 scrapes the metallic copper and anode mud backward, it may squeeze and adhere the metallic copper and anode mud to the upper rear side of the inner wall of the electrolytic cell 3. At this time, the control panel 4 will control the first electric push rod 18 to drive the lifting frame 19 and the sponge plate 20 to move upward and reset. Then, the control panel 4 will control the lead screw motor 17 to drive the slider 16 to continue to move backward a certain distance. The slider 16 can drive the first electric push rod 18, the lifting frame 19 and the sponge plate 20 to move backward a certain distance, so that the rear side of the sponge plate 20 is aligned with the rear side of the inner wall of the electrolytic cell 3. Then, the control panel 4 will control the first electric push rod 18 to drive the lifting frame 19 and the sponge plate 20 to move downward. The sponge plate 20 can scrape the metallic copper and anode mud adhering to the rear side of the inner wall of the electrolytic cell 3 downward, so that the metallic copper and anode mud can enter the discharge frame 5 for discharge through the rotation of the baffle frame 22. Then, the control panel 4 will control the first electric push rod 18 to drive the lifting frame 19 and the sponge plate 20 to move downward. The lifting frame 19 and the sponge plate 20 move upwards to reset; this operation repeats, ensuring that each time the rotating frame 7 rotates 90 degrees, one set of cathode plates 8 and one set of anode plates 9 are electrolyzed in a high-concentration copper-containing solution. The cathode plates 8 with metallic copper adhering to their surfaces and the anode plates 9 with anode mud adhering to their surfaces will intermittently rotate to the bottom of the cleaning assembly. The cleaning assembly automatically cleans the cathode plates 8, anode plates 9, and filter cloth 10, allowing the metallic copper and anode mud removed from the cathode plates 8, anode plates 9, and filter cloth 10 to be discharged through the discharge frame 5. When it is necessary to replace the cathode plates 8 and anode plates 9, the first drive motor 6 must first rotate the cathode plates 8 and anode plates 9 with the rotating frame 7 to the upper part of the rotating frame 7, and then pull the cathode plates 8 and anode plates 9 upwards, causing the insertion rod 13 to disengage from the first round hole 12 and the spring clip 11 to disengage from the second round hole 14, thus completing the disassembly.

[0034] Considering that the filter cloth 10 may become clogged after prolonged use, a flushing component was specially designed to ensure its filtration effect, such as... Figure 10 and Figure 11 As shown, the flushing assembly includes a water pump 28, a water suction pipe 29, a hose 30, a diversion pipe 31, and a nozzle 32. The water pump 28 is installed on the upper rear side of the support frame 1. Figure 1 (Described from the perspective shown) A water pump 28 is connected to the upper rear side of the sedimentation tank 2 by a water pumping pipe 29 and kept in communication. A diversion pipe 31 is connected inside the lifting frame 19. A hose 30 is connected to the top of the diversion pipe 31 and kept in communication. Multiple nozzles 32 are installed at intervals at the bottom of the lifting frame 19, and the lower end of the diversion pipe 31 is connected to the nozzles 32 and kept in communication.

[0035] When the filter cloth 10 needs to be rinsed, the water pump 28 can be started through the control panel 4. The water pump 28 can draw clean water from the sedimentation tank 2 through the water pipe 29, and deliver the clean water to the nozzle 32 through the hose 30 and the diversion pipe 31, so that the nozzle 32 can spray water downwards. At the same time, the screw motor 17 needs to be controlled to drive the slider 16 to move, thereby driving the lifting frame 19 to move back and forth. The lifting frame 19 can drive the diversion pipe 31 and the nozzle 32 to move back and forth, so that the nozzle 32 can rinse the filter cloth 10 below it, ensuring the filtration effect of the filter cloth 10.

[0036] like Figure 12 As shown, it also includes a cover plate 33, a second electric push rod 34, and an arc-shaped filter plate 35. The cover plate 33 is placed on the upper inner side of the sedimentation tank 2. The top of the cover plate 33 is symmetrically connected with handles on the left and right sides. The front and rear sides of the top of the cover plate 33 are symmetrically installed with second electric push rods 34. The arc-shaped filter plate 35 is connected between the telescopic rods of the four second electric push rods 34. The arc-shaped filter plate 35 is in contact with the inner wall of the sedimentation tank 2.

[0037] When wastewater settles in sedimentation tank 2, the arc-shaped filter plate 35 filters the sediment in sedimentation tank 2, preventing sediment from entering the drain pipe and causing blockage. Clean water can flow through the filter holes of the arc-shaped filter plate 35 to the drain pipe for discharge. As the usage time increases, sediment may adhere to the bottom of the arc-shaped filter plate 35, causing blockage of the filter holes. At this time, simply control the second electric push rod 34 through the control panel 4 to drive the arc-shaped filter plate 35 to move up and down. Whenever the arc-shaped filter plate 35 moves upward, the clean water above the arc-shaped filter plate 35 will quickly pass through the filter holes of the arc-shaped filter plate 35 due to pressure and reach the bottom of the arc-shaped filter plate 35, thereby automatically backwashing the arc-shaped filter plate 35. When it is necessary to add flocculant to sedimentation tank 2, simply pull the cover plate 33 upward to detach it from sedimentation tank 2, and then the flocculant can be added to sedimentation tank 2.

[0038] like Figure 12 As shown, it also includes a second drive motor 36 and a stirring frame 37. The second drive motor 36 is installed on the lower left side of the sedimentation tank 2, and the stirring frame 37 is rotatably connected to the lower inside of the sedimentation tank 2. The left end of the rotation shaft of the stirring frame 37 is connected to the output shaft of the second drive motor 36.

[0039] When the wastewater is settling in the sedimentation tank 2, the second drive motor 36 can be controlled by the control panel 4 to work at regular intervals. When the second drive motor 36 is working, it can drive the stirring frame 37 to rotate. The stirring frame 37 can stir the precipitant and wastewater in the sedimentation tank 2 to promote the mixing of the precipitant and wastewater. When the second drive motor 36 is not working, the wastewater can undergo normal chemical sedimentation.
