Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and in particular to a device and method for deeply intelligently treating circuit board electroplating wastewater. Background Art

[0002] Circuit board manufacturing is a key link in the electronics industry. Its production process involves multiple steps and processes, which are often accompanied by the generation of various wastewaters. These wastewaters may contain trace amounts of harmful substances such as chemicals, heavy metal ions, and suspended solids. If they are directly discharged, they will have a serious impact on the environment. Therefore, electroplating wastewater treatment has become an indispensable part of the circuit board manufacturing process. Among them, the use of sedimentation tanks is crucial to remove suspended solids and some soluble substances in wastewater.

[0003] For example, in the prior art, there is an automated circuit board electroplating wastewater treatment device and method with publication number CN117339257A. In the device, the electroplating wastewater that is statically precipitated in the sedimentation tank is extracted by a movable water suction pipe, and then the sludge is discharged through a lifting scraper plate in cooperation with a sewage pipe. Although it can avoid the problem of long-term contact between sewage and the scraper plate affecting the flexible use of the device, this sedimentation and sludge discharge method can only separate the wastewater separated by sedimentation, and cannot achieve in-depth separation and treatment of part of the wastewater in the sludge, and thus it is difficult to further treat this part of the electroplating wastewater.

Specific implementation manner

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment 1: Please refer to Figures 1 - 9 As shown, for the problem that the existing sedimentation and sludge discharge methods can only separate the wastewater separated by sedimentation and cannot achieve the deep separation and treatment of part of the wastewater in the sludge, the following solutions can be adopted: In this embodiment, the intelligent deep treatment device for printed circuit board electroplating wastewater includes a sedimentation tank 1. A squeezing type sludge discharge assembly 2 and an intercepting type water filtration assembly 3 are arranged in the sedimentation tank 1. The squeezing type sludge discharge assembly 2 includes a lifting platform 21 and two groups of rotating belts 22 installed on the outer side of the lifting platform 21. Rotating rollers 23 drivingly connected to the corresponding rotating belts 22 are rotatably installed at both ends of the lifting platform 21, and a plurality of obliquely arranged first scrapers 24 are equidistantly and fixedly connected to the rotating belts 22; By driving the rotating belt 22 to rotate through the rotating roller 23, driving a plurality of inclined first scrapers 24 to move forward or backward, the effect of integrating the deep extrusion separation of electroplating wastewater and sludge discharge and cleaning is achieved. Arc-shaped blocks cooperating with the first scrapers 24 are fixedly connected to both inner walls of the sedimentation tank 1, and through the cooperation of the arc-shaped blocks and the first scrapers 24, a comprehensive extrusion separation and sludge discharge and cleaning effect is achieved.

[0019] The intercept type water filtration component 3 includes a precision water filtration plate 31 fixedly connected between the arc-shaped blocks, which is used for the deep separation treatment after the precipitation drainage of electroplating wastewater. And water blocking plates 32 are equidistantly installed at the bottom of the precision water filtration plate 31. A plurality of water blocking plates 32 are located at the bottom of the precision water filtration plate 31 and are used to block the precision water filtration plate 31 when the electroplating wastewater of the circuit board is precipitated, so as to achieve the precipitation separation effect. A control panel is installed on the outer side of the sedimentation tank 1, and a drain pipe 11 is communicated below the precision water filtration plate 31. The bottom of the sedimentation tank 1 is inclined, and the drain pipe 11 is arranged at the lowest position to assist in the discharge of the separated wastewater, and a water flow sensor is provided on the drain pipe 11.

[0020] Two groups of fixed plates 12 are fixedly connected to the top of the sedimentation tank 1, and a water injection diamond tube 25 and a water absorption diamond tube 26 fixedly connected to the lifting platform 21 are respectively slidably connected to the two groups of fixed plates 12. The electroplating wastewater of the circuit board is injected into the water injection diamond tube 25 and then into the sedimentation tank 1 above the precision water filtration plate 31, waiting for the electroplating wastewater in the sedimentation tank 1 to stand and stratify, and the sludge impurities in the electroplating wastewater precipitate onto the precision water filtration plate 31; A connecting plate 27 is fixedly connected between the tops of the water injection diamond tube 25 and the water absorption diamond tube 26. The connecting plate 27 is used to combine the water injection diamond tube 25 and the water absorption diamond tube 26 to drive the lifting platform 21 to adjust its height, so as to avoid the problem that the squeezing type sludge discharging component 2 is in contact with the electroplating wastewater for a long time. An electric push rod 28 is connected between the connecting plate 27 and the fixed plate 12.

[0021] A water injection pipe 29 and a water suction pipe 210 are respectively fixedly communicated with the water injection diamond tube 25 and the water absorption diamond tube 26. The water suction pipe 210 is connected to an external water suction pump and is used to extract the electroplating wastewater after precipitation separation. A water suction cover 211 is fixedly communicated with the bottom of the water absorption diamond tube 26, and a filter screen is installed in the water suction cover 211. Through the contraction movement of the piston rod of the electric push rod 28, the connecting plate 27 combines the water absorption diamond tube 26 and the water injection diamond tube 25 to drive the lifting platform 21 to move downward; So that the water suction cover 211 contacts the upper layer of water after standing, and the external water suction pump cooperates with the water suction pipe 210, the water absorption diamond tube 26 and the water suction cover 211 to extract and discharge the upper layer of water. During the water suction process, a small amount of flowing impurities are blocked by the filter screen on the water suction cover 211 until the lifting platform 21 descends to the lowest position, and the partition type blocking realized by the contact between the plurality of scraping plates and the precision water filtration plate 31 is combined to realize the filtration and extraction of most of the lower layer of water, further improving the wastewater separation treatment while avoiding the problem that a large amount of sludge contacts the filter screen and reduces the drainage efficiency.

[0022] The outer side wall of the rotating roller 23 is provided with anti-slip ridges. The rotating belt 22 is provided with anti-deviation grooves that cooperate with the rotating roller 23. The lifting table 21 is provided with anti-deviation blocks (not shown in the figure) that slide with the anti-deviation grooves. Through the cooperation of the anti-deviation grooves and the anti-deviation blocks, the anti-deviation rotation of the rotating belt 22 on the lifting table 21 is realized. Moreover, the anti-deviation grooves are provided with anti-slip grooves that cooperate with the anti-slip ridges. Through the cooperation of the provided anti-slip ridges and anti-slip grooves, relative sliding between the rotating roller 23 and the rotating belt 22 is avoided, thereby achieving the stable rotation effect of the rotating belt 22; A double-shaft motor for driving the corresponding rotating roller 23 to rotate is installed on the lifting table 21 through bolts. The double-shaft electric motor is a waterproof motor. The double-shaft motor drives the rotating roller 23 to rotate. The rotating roller 23 drives the rotating belt 22 to rotate stably in combination with the anti-slip ridges and anti-slip grooves. The rotating belt 22 carries a plurality of first scraping plates 24 and slides on the top of the precision water filter plate 31, squeezing the sludge impurities onto the precision water filter plate 31 for extrusion-type deep separation treatment.

[0023] One side of the first scraping plate 24 is slidably connected to the second scraping plate 212. The first scraping plate 24, the second scraping plate 212 and the precision water filter plate 31 are in contact. Under the blockage of the first scraping plate 24 and the second scraping plate 212, the sludge impurities on the precision water filter plate 31 are partitioned and blocked. The lower-layer water between adjacent scraping plates will flow through the gaps between adjacent second scraping plates 212, and most of the lower-layer water is filtered and sucked out in combination with the filter screen; Then, while the rotating belt 22 carries a plurality of first scraping plates 24 and the second scraping plates 212 and slides on the top of the precision water filter plate 31 for extrusion separation, the second scraping plates 212 are in sliding contact with the filter screen, synchronously realizing the scraping of impurities on the filter screen. Moreover, a spring 213 is fixedly connected between the second scraping plate 212 and the first scraping plate 24. Limiting chute are symmetrically opened on both sides of the second scraping plate 212, and limiting sliders that slide with the corresponding limiting chute are fixedly connected to the inner side wall of the first scraping plate 24.

[0024] A plurality of installation grooves 33 are penetrated through the precision water filter plate 31. One side inside the installation groove 33 is rotatably connected to a triangular convex block 34 fixedly connected to the corresponding water blocking plate 32. Moreover, torsion springs 35 are fixedly connected between both sides of the triangular convex block 34 and the installation groove 33. During the process of the first scraping plate 24 and the second scraping plate 212 sliding on the top of the precision water filter plate 31, under the blockage of the triangular convex block 34, the continuous movement of the sludge impurities on the top of the precision water filter plate 31 is restricted, thereby realizing the extrusion and discharge of the electroplating wastewater in the sludge impurities; During the extrusion process, the scraping plate contacts the triangular convex block 34, prompting the triangular convex block 34 to carry the water blocking plate 32 to deflect downward and twist the torsion spring 35. The downward-deflected water blocking plate 32 does not block the precision water filter plate 31 in this area, so that the lower-layer water separated by extrusion passes through the precision water filter plate 31 and filters to the bottom of the sedimentation tank 1, and then is collected and discharged through the drain pipe 11; After the scraper is separated from the triangular bump 34, under the action of the torsional elastic force of the torsion spring 35, the water blocking plate 32 is driven to reset and impact the precision water filtering plate 31, secondarily assisting in vibrating and separating the lower layer of water, realizing a multi-stage rapid separation combining extrusion and vibration for the wastewater in the sediment sludge, achieving a deep separation treatment, and further improving the separation efficiency and effect of electroplating wastewater and sludge.

[0025] Embodiment 2: Please refer to Figures 2 - 7 With Figure 10 As shown, for the problem of convenient discharge of the separated sludge, the following solutions can be adopted: In this embodiment, the intercepting water filtering assembly 3 includes a precision water filtering plate 31 fixedly connected between the arc-shaped blocks, and water blocking plates 32 are equidistantly installed at the bottom of the precision water filtering plate 31. A control panel is installed on the outer side of the sedimentation tank 1, and a drain pipe 11 is communicated below the precision water filtering plate 31, and a water flow sensor is provided on the drain pipe 11. The lower layer of water separated by extrusion and vibration passes through the precision water filtering plate 31 and is filtered to the bottom of the sedimentation tank 1, and then is collected and discharged through the drain pipe 11; The water flow sensor in the drain pipe 11 collects data on the drainage flow rate, and transmits the collected data detected to the controller in the control panel. The controller compares the collected data with the set data until the collected data is less than the set data, and the controller controls the double-shaft motor to drive the rotating roller 23 to cause the rotating belt 22 to rotate in the reverse direction for sludge discharge treatment.

[0026] One side of the first scraper 24 is slidably connected with a second scraper 212, and a spring 213 is fixedly connected between the second scraper 212 and the first scraper 24. Limiting sliding grooves are symmetrically opened on both sides of the second scraper 212, and limiting sliding blocks that slide with the corresponding limiting sliding grooves are fixedly connected to the inner side wall of the first scraper 24; During the sludge discharge process, when the second scraper 212 contacts the water absorption diamond tube 26 or the water injection diamond tube 25 through the rotation of the rotating belt 22, the second scraper 212 is caused to compress the spring 213 and move. When the second scraper 212 is separated from the water absorption diamond tube 26 or the water injection diamond tube 25, under the compression elastic force of the spring 213, the second scraper 212 is caused to move, causing the limiting sliding block to impact the limiting sliding groove to form vibration, thereby vibrating and separating the sludge on the scraper and achieving self-cleaning of the sludge on the scraper.

[0027] A sludge discharge port 13 penetrating the sedimentation tank 1 is opened on one side arc-shaped block. The scraper on the rotating belt 22 contacts the precision water filtering plate 31, pushing the sludge towards the sludge discharge port 13, and an arc-shaped blocking groove communicated with the sludge discharge port 13. A rubber blocking plate 14 is slidably connected in the arc-shaped blocking groove, and a counterweight 15 is fixedly connected to the top of the rubber blocking plate 14. The setting of the counterweight 15 is used to squeeze the rubber blocking plate 14 to complete the blocking of the sludge discharge port 13; On one side of the counterweight block 15, an elastic linkage block 16 that cooperates with the first scraper 24 is fixedly connected. The elastic property of the elastic linkage block 16 can avoid interfering with the forward rotation of the scraper. At the same time, combined with the reverse rotation of the scraper, the counterweight block 15 moves. Combined with the contact between the scraper and the elastic linkage block 16, the counterweight block 15 drives the rubber plugging plate 14 to move upward in the arc-shaped plugging groove, thereby intermittently opening the sludge discharge port 13. Combined with the scraper pushing the sludge to move, the self-discharge effect of the sludge is realized.

[0028] Embodiment 3: Please refer to Figures 1 - 10 As shown in the figure, the present invention also proposes a method for deep intelligent treatment of printed circuit board electroplating wastewater, including the following contents: Step 1: Injection and sedimentation treatment, and the specific process is as follows: Introduce the printed circuit board electroplating wastewater into the injection diamond tube 25 through the injection pipe 29, and then inject it into the sedimentation tank 1 above the precision water filter plate 31. Wait for the electroplating wastewater in the sedimentation tank 1 to stand and stratify, and the sludge impurities in the electroplating wastewater precipitate onto the precision water filter plate 31; Step 2: Upper water barrier extraction link, and the specific process is as follows: Connect the suction pipe 210 to an external suction pump. The piston rod of the electric push rod 28 contracts, prompting the connecting plate 27 to drive the lifting platform 21 to move downward in combination with the suction diamond tube 26 and the injection diamond tube 25, so that the suction hood 211 contacts the upper water after standing. The external suction pump cooperates with the suction pipe 210, the suction diamond tube 26 and the suction hood 211 to extract and discharge the upper water. During the suction process, a small amount of flowing impurities are blocked by the filter screen on the suction hood 211 until the lifting platform 21 descends to the lowest point. The first scraper 24 contacts the second scraper 212 and the precision water filter plate 31. Under the blockage of the first scraper 24 and the second scraper 212, the sludge impurities on the precision water filter plate 31 are blocked. The lower water between adjacent scrapers flows through the gaps between adjacent second scrapers 212, and most of the lower water is filtered and sucked out in combination with the filter screen. Then stop the external suction pump and stop the suction link; Step 3: The process of squeezing and separating and discharging the lower water, and the specific process is as follows: The double-shaft motor drives the rotating roller 23 to rotate. The rotating roller 23 drives the rotating belt 22 to rotate stably in combination with the anti-slip ridges and anti-slip grooves. The rotating belt 22 carries a plurality of first scrapers 24 and second scrapers 212 to slide on the top of the precision water filter plate 31, and slides in contact with the filter screen through the second scraper 212 to scrape the impurities on the filter screen. Under the blockage of the triangular protrusions 34, the continuous movement of the sludge impurities on the top of the precision water filter plate 31 is restricted, and then the lower water in the sludge impurities is squeezed out; During the extrusion process, the scraper contacts the triangular bump 34, causing the triangular bump 34 to drive the water blocking plate 32 to deflect downward and twist the torsion spring 35. The downward-deflected water blocking plate 32 does not block the precision water filtering plate 31 in this area, so that the lower-layer water separated by extrusion passes through the precision water filtering plate 31 and is filtered to the bottom of the sedimentation tank 1, and then is collected and discharged through the drain pipe 11. When the scraper separates from the triangular bump 34, under the action of the torsional elastic force of the torsion spring 35, the water blocking plate 32 is driven to reset and impact the precision water filtering plate 31 to assist in vibrating and separating the lower-layer water, further accelerating the separation efficiency; Step 4: Self-cleaning sludge discharge method, the specific process is as follows: The water flow sensor in the drain pipe 11 collects data on the drainage flow rate and transmits the collected data detected to the controller in the control panel. The controller compares the collected data with the set data until the collected data is less than the set data. The controller controls the double-shaft motor to drive the rotating roller 23 to cause the rotating belt 22 to rotate in the reverse direction. The scraper on the rotating belt 22 contacts the precision water filtering plate 31, pushes the sludge towards the sludge discharge port 13, and combines with the contact between the scraper and the elastic linkage block 16 to drive the counterweight block 15 to carry the rubber blocking plate 14 to move upward in the arc-shaped blocking groove, thereby intermittently opening the sludge discharge port 13, and combining with the movement of the scraper to push the sludge to achieve self-discharge of the sludge; When the second scraper 212 contacts the water absorption diamond tube 26 or the water injection diamond tube 25, the second scraper 212 is caused to move by compressing the spring 213. When the second scraper 212 separates from the water absorption diamond tube 26 or the water injection diamond tube 25, under the compression elastic force of the spring 213, the second scraper 212 is caused to move, resulting in the limit slider impacting the limit sliding groove to form vibration, thereby vibrating and separating the sludge on the scraper to achieve self-cleaning.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
