Description

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 critical component of the electronics industry. Its production process involves multiple steps and processes, often resulting in the generation of various wastewaters. These wastewaters may contain trace amounts of harmful substances such as chemicals, heavy metal ions, and suspended solids, which, if discharged directly, would have a serious impact on the environment. Therefore, electroplating wastewater treatment has become an integral part of the circuit board manufacturing process, and the use of sedimentation tanks is crucial for removing suspended solids and some soluble substances from the wastewater.

[0003] For example, in the prior art, there is an automated device and method for treating electroplating wastewater from circuit boards with publication number CN117339257A. In this device, electroplating wastewater that has been stagnant and settled in a sedimentation tank is extracted by a movable water suction pipe, and then the sludge is discharged by a lifting scraper in conjunction with a sewage pipe. Although this method can avoid the problem of long-term contact between sewage and the scraper 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 achieve further treatment of this part of the electroplating wastewater.

[0034] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figures 1-9 As shown, the sedimentation and sludge discharge method in the prior art can only separate the wastewater separated by sedimentation, and cannot achieve in-depth separation and treatment of part of the wastewater in the sludge. This problem can be solved by the following solution:

[0036] In this embodiment, the circuit board electroplating wastewater deep intelligent treatment device includes a sedimentation tank 1, in which a water squeezing mud discharge assembly 2 and an intercepting water filtration assembly 3 are provided. The water squeezing mud discharge assembly 2 includes a lifting platform 21 and two sets of rotating belts 22 installed on the outside of the lifting platform 21. Rotating rollers 23 that are transmission-connected to the corresponding rotating belts 22 are rotatably mounted at both ends of the lifting platform 21. A plurality of inclined first scrapers 24 are fixedly connected to the rotating belts 22 at equal intervals.

[0037] The rotating belt 22 is driven to rotate by the rotating roller 23, which drives multiple inclined first scrapers 24 to move forward or reverse, thereby achieving a two-in-one effect of in-depth electroplating wastewater extrusion separation and sludge cleaning. Arc blocks that cooperate with the first scrapers 24 are fixedly connected to the inner walls of both sides of the sedimentation tank 1. The arc blocks cooperate with the first scrapers 24 to achieve comprehensive extrusion separation and sludge cleaning effects.

[0038] The intercepting water filter assembly 3 includes a precision water filter plate 31 fixedly connected between the arc blocks, which is used for in-depth separation treatment of electroplating wastewater after sedimentation and drainage, and water blocking plates 32 are equidistantly installed at the bottom of the precision water filter plate 31. Multiple water blocking plates 32 are located at the bottom of the precision water filter plate 31, which are used to block the precision water filter plate 31 when the circuit board electroplating wastewater is precipitated, thereby achieving the sedimentation and separation effect. A control panel is installed on the outside of the sedimentation tank 1, and a drain pipe 11 is connected to the bottom of the precision water filter plate 31. The bottom of the sedimentation tank 1 is inclined, and the drain pipe 11 is set at the lowest point to assist in the discharge of separated wastewater, and a water flow sensor is provided on the drain pipe 11.

[0039] Two sets of fixed plates 12 are fixedly connected to the top of the sedimentation tank 1, and the two sets of fixed plates 12 are respectively slidably connected to the water injection diamond tube 25 and the water absorption diamond tube 26 fixed to the lifting platform 21. The circuit board electroplating wastewater is injected into the water diamond tube 25 and then injected into the sedimentation tank 1 located above the precision water filter plate 31. The electroplating wastewater in the sedimentation tank 1 is allowed to stand and stratify, and the sludge impurities in the electroplating wastewater are precipitated onto the precision water filter plate 31.

[0040] A connecting plate 27 is fixedly connected between the tops of the water injection diamond tube 25 and the water suction diamond tube 26. The connecting plate 27 is used to combine the water injection diamond tube 25 and the water suction diamond tube 26 to drive the lifting platform 21 to adjust the height, thereby facilitating the avoidance of the problem of long-term contact between the water-squeezing mud discharge assembly 2 and the electroplating wastewater. An electric push rod 28 is connected between the connecting plate 27 and the fixed plate 12.

[0041] The water injection diamond tube 25 and the water suction diamond tube 26 are respectively fixedly connected with a water injection pipe 29 and a water suction pipe 210. The water suction pipe 210 is connected to an external water suction pump to extract the electroplating wastewater after sedimentation separation. The bottom of the water suction diamond tube 26 is fixedly connected with a water suction cover 211, and a filter is installed in the water suction cover 211. The piston rod of the electric push rod 28 contracts and moves, prompting the connecting plate 27 to combine with the water suction diamond tube 26 and the water injection diamond tube 25 to drive the lifting platform 21 to move downward;

[0042] This causes the water absorption hood 211 to come into contact with the upper layer of water after standing still. The external water absorption pump cooperates with the water absorption pipe 210, the water absorption diamond tube 26 and the water absorption hood 211 to extract the upper layer of water for discharge. During the water absorption process, a small amount of flowing impurities are blocked by the filter screen on the water absorption hood 211 until the lifting platform 21 drops to the lowest point. Combined with the partitioned blockage achieved by the contact of multiple scrapers and the precision water filter plate 31, most of the lower layer water is filtered and extracted, further improving the wastewater separation and treatment while avoiding the problem of a large amount of sludge contacting the filter screen to reduce drainage efficiency.

[0043] The outer wall of the rotating roller 23 is provided with an anti-slip ridge, and the rotating belt 22 is provided with an anti-deflection groove that cooperates with the rotating roller 23. The lifting platform 21 is provided with an anti-deflection block (not shown) that slides with the anti-deflection groove. The anti-deflection groove cooperates with the anti-deflection block to achieve anti-deflection rotation of the rotating belt 22 on the lifting platform 21. The anti-deflection groove is provided with an anti-slip groove that cooperates with the anti-slip ridge. The cooperation between the anti-slip ridge and the anti-slip groove prevents relative sliding between the rotating roller 23 and the rotating belt 22, thereby achieving a stable rotation effect of the rotating belt 22.

[0044] A double-axis motor that drives the corresponding rotating roller 23 to rotate is installed on the lifting platform 21 through bolts. The double-axis electric motor adopts a waterproof motor. The double-axis motor drives the rotating roller 23 to rotate. The rotating roller 23 combines the anti-skid ridges and anti-skid grooves to drive the rotating belt 22 to rotate stably. The rotating belt 22 carries multiple first scrapers 24 to slide 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.

[0045] A second scraper 212 is slidably connected to one side of the first scraper 24. The first scraper 24 contacts the second scraper 212 and the precision water filter plate 31. Under the obstruction of the first scraper 24 and the second scraper 212, the sludge and impurities on the precision water filter plate 31 are blocked in a zoned manner, while the lower layer of water between adjacent scrapers flows through the gaps between adjacent second scrapers 212, and combined with the filter screen, most of the lower layer of water is filtered, sucked and discharged;

[0046] Then, the rotating belt 22 carries multiple first scrapers 24 and second scrapers 212 to slide on the top of the precision water filter plate 31 for extrusion and separation. At the same time, the second scraper 212 slides in contact with the filter screen to synchronously scrape off impurities on the filter screen. A spring 213 is fixedly connected between the second scraper 212 and the first scraper 24. Limiting grooves are symmetrically provided on both sides of the second scraper 212. A limiting slider that slides with the corresponding limiting groove is fixedly connected to the inner wall of the first scraper 24.

[0047] The precision water filter plate 31 is provided with a plurality of mounting grooves 33, and a triangular protrusion 34 fixedly connected to the corresponding water blocking plate 32 is rotatably connected to one side of the mounting groove 33. Torsion springs 35 are fixedly connected between the two sides of the triangular protrusion 34 and the mounting groove 33. When the first scraper 24 and the second scraper 212 slide on the top of the precision water filter plate 31, the triangular protrusion 34 blocks the sludge impurities from continuing to move on the top of the precision water filter plate 31, thereby squeezing out the electroplating wastewater contained in the sludge impurities.

[0048] During the squeezing process, the scraper contacts the triangular protrusion 34, causing the triangular protrusion 34 to carry the water blocking plate 32 to deflect downward, and twisting the torsion spring 35. The downwardly deflected water blocking plate 32 does not block the precision water filter plate 31 in this area, so that the lower layer of water separated by squeezing is filtered through the precision water filter plate 31 to the bottom of the sedimentation tank 1, and then collected and discharged through the drain pipe 11;

[0049] When the scraper is separated from the triangular protrusion 34, under the action of the twisting elastic force of the torsion spring 35, the water blocking plate 32 is driven to reset and hit the precision water filter plate 31, and the secondary auxiliary vibration is used to separate the lower layer of water, and the wastewater in the sedimentation sludge is quickly separated by a multi-stage method combining extrusion and vibration, achieving in-depth separation treatment, and further improving the separation efficiency and effect of electroplating wastewater and sludge.

[0050] Example 2: Please refer to Figure 2-Figure 7 and Figure 10 As shown in the figure, the problem of convenient discharge of sludge after separation can be solved by the following solutions:

[0051] In this embodiment, the intercepting water filter assembly 3 includes a precision water filter plate 31 fixedly connected between the arc-shaped blocks, and a water blocking plate 32 is equidistantly installed at the bottom of the precision water filter plate 31. A control panel is installed on the outside of the sedimentation tank 1, and a drain pipe 11 is connected below the precision water filter plate 31. The drain pipe 11 is provided with a water flow sensor. The lower layer of water separated by squeezing and vibration is filtered through the precision water filter plate 31 to the bottom of the sedimentation tank 1, and then collected and discharged through the drain pipe 11.

[0052] The drainage flow rate is collected through the water flow sensor in the drainage pipe 11, and the collected data is transmitted 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 dual-axis motor to drive the rotating roller 23 to force the rotating belt 22 to rotate in the opposite direction for mud discharge processing.

[0053] A second scraper 212 is slidably connected to one side of the first scraper 24, and a spring 213 is fixedly connected between the second scraper 212 and the first scraper 24. Limiting grooves are symmetrically provided on both sides of the second scraper 212, and a limiting slider is fixedly connected to the inner side wall of the first scraper 24 to slide in the corresponding limiting groove.

[0054] During the sludge discharge process, through the rotation of the rotating belt 22, when the second scraper 212 contacts the water suction diamond tube 26 or the water injection diamond tube 25, the second scraper 212 compresses the spring 213 to move. When the second scraper 212 separates from the water suction diamond tube 26 or the water injection diamond tube 25, the compressed elastic force of the spring 213 prompts the second scraper 212 to move, causing the limiting slider to hit the limiting slide groove to form vibration, thereby vibrating and separating the sludge on the scraper, achieving self-cleaning of the sludge on the scraper.

[0055] A mud outlet 13 penetrating the sedimentation tank 1 is provided on one side of the arc block. The scraper on the rotating belt 22 contacts the precision water filter plate 31 to push the sludge toward the mud outlet 13. There is also an arc-shaped plugging groove communicating with the mud outlet 13. A rubber plugging plate 14 is slidably connected in the arc-shaped plugging groove. A counterweight block 15 is fixedly connected to the top of the rubber plugging plate 14. The counterweight block 15 is provided to squeeze the rubber plugging plate 14 to complete the plugging of the mud outlet 13.

[0056] One side of the counterweight block 15 is fixedly connected to an elastic linkage block 16 that cooperates with the first scraper 24. The elastic properties of the elastic linkage block 16 can avoid interfering with the forward rotation of the scraper, and at the same time, combined with the reverse rotation of the scraper, the counterweight block 15 can be moved. Combined with the contact between the scraper and the elastic linkage block 16, the counterweight block 15 is driven to carry the rubber plugging plate 14 to move upward in the arc-shaped plugging groove, thereby intermittently opening the mud discharge port 13, and combined with the scraper to promote the movement of the sludge, to achieve the self-draining effect of the sludge.

[0057] Example 3: Please refer to Figures 1-10 As shown, the present invention also proposes a deep intelligent treatment method for circuit board electroplating wastewater, including the following contents:

[0058] Step 1: Water injection and sedimentation treatment. The specific process is as follows: the circuit board electroplating wastewater is introduced into the water injection diamond pipe 25 through the water injection pipe 29, and then injected into the sedimentation tank 1 located above the precision water filter plate 31. The electroplating wastewater in the sedimentation tank 1 is allowed to stand and stratify, and the sludge impurities in the electroplating wastewater are precipitated onto the precision water filter plate 31;

[0059] Step 2: The upper water barrier extraction link, the specific process is as follows: connect the water suction pipe 210 to the external water suction pump, the piston rod of the electric push rod 28 contracts, prompting the connecting plate 27 to combine with the water suction diamond pipe 26 and the water injection diamond pipe 25 to drive the lifting platform 21 to move downward, so that the water suction cover 211 contacts the upper water after standing, and the external water suction pump cooperates with the water suction pipe 210, the water suction diamond pipe 26 and the water suction cover 211 to extract the upper water for discharge, and in the process of water suction, a small amount of impurities flowing The filter screen on the water absorption cover 211 is used to block the water until the lifting platform 21 drops to the lowest point. The first scraper 24 contacts the second scraper 212 and the precision water filter plate 31. Under the obstruction of the first scraper 24 and the second scraper 212, the sludge and impurities on the precision water filter plate 31 are blocked. The lower layer of water between adjacent scrapers flows through the gap between adjacent second scrapers 212 and is filtered and sucked out by the filter screen. Then the external water suction pump is stopped, and the water suction process is stopped.

[0060] Step 3: The lower layer of water is separated and discharged by squeezing. The specific process is as follows: The dual-axis motor drives the rotating roller 23 to rotate. The rotating roller 23, combined with the anti-skid ridges and anti-skid grooves, drives the rotating belt 22 to rotate stably. The rotating belt 22 carries multiple first scrapers 24 and second scrapers 212 to slide on the top of the precision water filter plate 31. The second scrapers 212 slide in contact with the filter screen to scrape off impurities on the filter screen. Under the obstruction of the triangular protrusions 34, the sludge impurities are restricted from continuing to move on the top of the precision water filter plate 31, thereby squeezing out the lower layer of water in the sludge impurities.

[0061] During the extrusion process, the scraper contacts the triangular protrusion 34, causing the triangular protrusion 34 to carry the water blocking plate 32 to deflect downward and twist the torsion spring 35. The downwardly deflected water blocking plate 32 does not block the precision water filter plate 31 in this area, so that the lower layer of water separated by squeezing is filtered through the precision water filter plate 31 to the bottom of the sedimentation tank 1 and then collected and discharged through the drain pipe 11. When the scraper separates from the triangular protrusion 34, under the twisting elastic force of the torsion spring 35, the water blocking plate 32 is driven to return to its original position and hit the precision water filter plate 31 to assist in the vibration separation of the lower layer of water, further accelerating the separation efficiency.

[0062] Step 4: Self-cleaning sludge discharge method, the specific process is as follows: the drainage flow rate is collected through the water flow sensor in the drainage pipe 11, and the collected data is transmitted 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 dual-axis motor to drive the rotating roller 23 to cause the rotating belt 22 to rotate in the opposite direction. The scraper on the rotating belt 22 contacts the precision water filter plate 31, pushing the sludge to move toward the sludge discharge port 13, and combined with the contact between the scraper and the elastic linkage block 16, drives the counterweight block 15 and the rubber plugging plate 14 to move upward in the arc plugging groove, thereby intermittently opening the sludge discharge port 13, and combined with the scraper to push the sludge to move, realizing the sludge self-drainage;

[0063] When the second scraper 212 contacts the water suction diamond tube 26 or the water injection diamond tube 25, the second scraper 212 compresses the spring 213 and moves. When the second scraper 212 separates from the water suction diamond tube 26 or the water injection diamond tube 25, the compressed elastic force of the spring 213 prompts the second scraper 212 to move, causing the limiting slider to hit the limiting slide groove to vibrate, thereby vibrating and separating the sludge on the scraper to achieve self-cleaning.

[0064] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
