Description

Technical Field

[0001] This invention relates to the field of chemical treatment technology for electroplating solutions, and more specifically to a water treatment device and method for electroplating solutions. Background Technology

[0002] Electroplating solution is a chemical solution used in the electroplating process. During electroplating, various chemical reactions and cleaning operations generate a large amount of wastewater containing heavy metal ions (such as chromium, copper, nickel, etc.), acidic and alkaline substances, and other chemical substances. If this wastewater is discharged directly without treatment, it will cause serious environmental pollution, including soil pollution, water pollution (causing heavy metals in water to exceed standards, changing the pH of water, etc.), and ecological damage. Therefore, water treatment sedimentation tanks are needed to use chemical reactions to precipitate heavy metal ions and other solid particles in the wastewater, thereby separating them from the wastewater and removing harmful substances, allowing the treated water to be recycled. However, the quality and quantity of wastewater fluctuate greatly during the production process. Wastewater generated at different times flows into the sedimentation tank first, and then a large amount of wastewater that enters the sedimentation tank later stirs up the water in the tank. This causes the water flow rate to be too fast, preventing the chemical reagents from reacting fully with the wastewater. As a result, the solid particles in the wastewater do not have enough time to settle, affecting the quality of wastewater treatment. Summary of the Invention

[0003] The purpose of this invention is to provide a water treatment device and method for electroplating solutions to address the aforementioned shortcomings in the technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a water treatment device and method for electroplating solutions, comprising a chemical treatment tank and an inlet / outlet pipe. The bottom of the chemical treatment tank is equipped with an outlet pipe communicating with its interior. A treatment component is connected between the chemical treatment tank and the inlet / outlet pipe. The treatment component is used to maintain a drop in the wastewater within the chemical treatment tank for backflow treatment, ensuring sufficient contact between the wastewater and chemical reagents within the chemical treatment tank. A flow-slowing component is connected between the chemical treatment tank and the treatment component, and this component is used to intercept wastewater particles overflowing from the top of the chemical treatment tank, ensuring stable treatment of the wastewater within the chemical treatment tank. A diversion component, cooperating with the treatment component, is installed at the bottom of the chemical treatment tank to maintain appropriate gaps between the slowly flowing particles within the chemical treatment tank, ensuring thorough mixing of the wastewater and chemical reagents within the chemical treatment tank.

[0005] Preferably, the treatment assembly includes a conical tube installed between the chemical treatment tank and the inlet / outlet pipe, and an overflow ring fixedly fitted to the top of the chemical treatment tank. The conical tube has a conical internal structure. A centering ring is fixedly connected inside the overflow ring, and an overflow trough is formed between the centering ring and the overflow ring to guide and collect the overflowing wastewater. An outlet pipe communicating with the inside of the overflow trough is fixedly connected to the outside of the overflow ring.

[0006] Preferably, a perforated ring frame is fixedly connected inside the chemical treatment tank, and the perforated ring frame is used to slow down the flow of wastewater to ensure that the wastewater is evenly dispersed in the chemical treatment tank. A limiting cylinder is fixedly connected to the middle of the perforated ring frame, and the bottom of the limiting cylinder is located inside the conical tube and sleeved on the outside of the waste inlet pipe.

[0007] Preferably, the slow-flow assembly includes an overflow weir ring rotatably connected to the top of the centering ring and a second toothed ring rotatably connected to the side of the chemical treatment tank near the centering ring. A first toothed ring is fixedly connected to the side of the overflow weir ring near the second toothed ring. A perforated ring plate is fixedly connected inside the second toothed ring, and the perforated ring plate is rotatably sleeved on the outside of the limiting cylinder.

[0008] Preferably, a gear that meshes with the second gear ring and the first gear ring is rotatably connected to one side of the centering ring. A first servo motor is fixedly connected to the outside of the overflow ring, and the first servo motor is used to drive the gear to rotate. A sealing ring is connected between the centering ring and the overflow ring, and the sealing ring is sleeved on the outside of the output end of the first servo motor.

[0009] Preferably, a plurality of support blocks are fixedly connected to the top of the perforated ring plate, and one side of the support block is attached to the outside of the limiting cylinder. A wedge is fixedly connected to the top of the support block and is located inside the limiting cylinder. A guide frame is fixedly connected to the side of the wedge away from the limiting cylinder, and the guide frame and the wedge are combined to form an X-shaped structure.

[0010] Preferably, the diversion assembly includes a stabilizing rod fixedly connected to the bottom wall inside the chemical treatment tank and a movable sleeve slidably sleeved outside the stabilizing rod. The movable sleeve is used for inserting and removing the bottom opening of the conical tube. Two symmetrical connecting rods are fixedly connected to the outside of the movable sleeve, and a connecting sleeve is movably connected to the top of the connecting rod. A guide column is slidably sleeved inside the connecting sleeve. A power column is rotatably connected to the inner wall of the chemical treatment tank. A curved block is connected between the guide column and the power column. A second servo motor is fixedly connected to the outside of the chemical treatment tank, and the second servo motor is used to drive the power column to rotate.

[0011] A method for treating water in an electroplating solution using a water treatment device includes the following steps: S1. The wastewater is connected to the external wastewater discharge pipe through the wastewater inlet pipe. The wastewater inlet pipe then guides the wastewater into the interior of the chemical treatment tank. At this time, the wastewater is added into the interior of the chemical treatment tank and mixed with the chemical reagents inside the chemical treatment tank to chemically precipitate the particulate impurities in the wastewater. S2. Secondly, during the process of the wastewater being guided into the chemical treatment tank by the wastewater inlet pipe, the treatment component is used to guide the wastewater output from the wastewater inlet pipe. At this time, the wastewater moves from bottom to top in the treatment component. Then, the wastewater flows into the conical tube in the treatment component due to inertia. The conical tube guides the wastewater into the chemical treatment tank. Moreover, the wastewater flows in a throat-like manner between the conical tube and the chemical treatment tank, allowing sufficient contact time between it and the chemical reagents. As a result, the wastewater forms sediment between the conical tube and the chemical treatment tank. S3. Next, the waste inlet pipe continuously draws wastewater into the conical cylinder and the chemical treatment tank. Soon, the conical cylinder and the chemical treatment tank are full of wastewater, and the wastewater overflows outward along the inside of the limiting cylinder. At this time, the limiting cylinder discharges wastewater from different directions in the chemical treatment tank, which further disperses the wastewater in the conical cylinder and the chemical treatment tank. The wastewater inside the chemical treatment tank overflows from the top of the chemical treatment tank, allowing the wastewater mixed with chemical reagents to be discharged outward. Moreover, the waste inlet pipe keeps the wastewater inside the conical cylinder in a flowing state, so that the continuous wastewater interacts with the chemical reagents and the overflowing wastewater in the conical cylinder and the chemical treatment tank, further improving the contact between the wastewater and the chemical reagents. S4. The flow-retarding component is used to block the overflow of wastewater between the treatment component and the chemical treatment tank, and to intercept the particles that float briefly in the wastewater, so that the particles in the wastewater can settle fully in the chemical treatment tank and the conical tube. S5. Subsequently, the diversion component is used to create slight multidimensional fluctuations in the wastewater and particles between the chemical treatment tank and the conical tube. The wastewater and particles then maintain flow, and the chemical reagents are in full contact with the wastewater in the chemical treatment tank and the conical tube, thereby improving the wastewater treatment quality.

[0012] The technical effects and advantages provided by the present invention in the above technical solution are as follows: 1. By setting up the treatment components, chemical treatment tank and waste inlet pipe, the present invention enables wastewater to move back and forth from top to bottom and then from bottom to top inside the waste inlet pipe, chemical treatment tank and treatment components. During the flow, the wastewater flows at a relatively slow speed and travels a long distance. This continuous water flow makes the wastewater treatment effect in the chemical treatment tank more stable, which is conducive to the full reaction between wastewater and chemical reagents. It reduces the impact of wastewater volume or water quality fluctuations on the treatment effect and improves the quality of wastewater treatment. 2. By setting up a limiting cylinder, a perforated ring frame, an inlet pipe, and a conical tube, this invention can maintain a slow flow state when wastewater flows near the perforated ring frame, allowing the wastewater to interact with each other. This improves the water flow state, reduces short-circuiting, and allows the chemical treatment tank to better adapt to fluctuations in water volume. When the water volume increases, the mixing effect can make the wastewater more evenly distributed in the chemical treatment tank, avoiding the impact of excessive local water volume on the sedimentation effect. This ensures that the wastewater can maintain sufficient contact with chemical reagents in the chemical treatment tank and achieve particle sedimentation, thereby improving the treatment effect. 3. By setting up a centering ring, an overflow weir ring, a chemical treatment tank, and a limiting cylinder, this invention can prevent particulate impurities from being discharged simultaneously with the overflowing wastewater. After the overflowing wastewater is blocked by impurities, the particulate impurities form a temporary accumulation at the opening of the centering ring. During this process, the wastewater needs to pass through the particulate impurities and move closer to the overflow weir ring, which is beneficial for blocking the remaining fine impurities. This makes the water flow in the chemical treatment tank and the centering ring more stable, further increasing the contact time between the wastewater and the chemical reagents in the chemical treatment tank and improving the wastewater treatment efficiency. 4. By setting up an overflow weir ring, a perforated ring frame, a first servo motor, and gears, this invention can disturb the wastewater at the bottom of the perforated ring frame and the wastewater near the intersection of the perforated ring plate and the perforated ring frame. This allows the continuous inflow and mixing of wastewater to break the local static state, so that the wastewater and particulate impurities are evenly distributed throughout the chemical treatment tank and the waste inlet pipe. This avoids excessive accumulation of local sediments, which would affect the normal operation of the chemical treatment tank and ensure that the chemical reagents work evenly throughout the chemical treatment tank and the conical tube. 5. By setting up support blocks, wedges, limiting cylinders, perforated ring frames, and perforated ring plates, this invention can increase the turbulence in the wastewater near the limiting cylinder, prevent wastewater and particulate impurities from depositing and clogging at the opening of the limiting cylinder, maintain the continuous delivery of wastewater to the limiting cylinder, and enable the wastewater to contact the chemical reagents more quickly, thus accelerating the reaction process. 6. By setting up a conical tube, a chemical treatment tank, and a diversion component, this invention can not only loosen the particulate impurities at the bottom of the conical tube, but also enable multi-dimensional flow of particulate impurities and wastewater within the chemical treatment tank and conical tube. This ensures sufficient contact between the particulate impurities, wastewater, and chemical reagents, which is beneficial for continuous reaction of wastewater within the chemical treatment tank and conical tube, thereby improving wastewater treatment efficiency.

Detailed Implementation

[0016] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0017] This invention provides, for example Figure 1 , Figure 2 and Figure 3As shown, a water treatment device and method for electroplating solutions include a chemical treatment tank 1 and an inlet / outlet pipe 12. An outlet pipe 11 communicating with the bottom of the chemical treatment tank 1 is installed therein. A treatment component 2 is connected between the chemical treatment tank 1 and the inlet / outlet pipe 12. The treatment component 2 is used to maintain a drop in the wastewater in the inlet / outlet pipe 12 within the chemical treatment tank 1 for backflow treatment, ensuring sufficient contact between the wastewater and chemical reagents within the chemical treatment tank 1. A flow-retarding component 3 is connected between the chemical treatment tank 1 and the treatment component 2, and the flow-retarding component 3 is used to intercept particulate impurities overflowing from the top of the chemical treatment tank 1, ensuring stable treatment of the wastewater within the chemical treatment tank 1. A diversion component 4, which cooperates with the treatment component 2, is installed at the bottom of the chemical treatment tank 1 to maintain appropriate gaps between the slowly flowing particles within the chemical treatment tank 1, ensuring sufficient mixing of the wastewater and chemical reagents within the chemical treatment tank 1. refer to Figure 2 , Figure 3 and Figure 4 As shown, the treatment component 2 includes a conical tube 21 installed between the chemical treatment tank 1 and the waste inlet pipe 12 and an overflow ring 22 fixedly sleeved on the top of the chemical treatment tank 1. The conical tube 21 has a conical structure inside. A centering ring 23 is fixedly connected inside the overflow ring 22. An overflow trough 24 is formed between the centering ring 23 and the overflow ring 22 to guide and collect the overflowing wastewater. An outlet pipe 25 is fixedly connected to the outside of the overflow ring 22 and communicates with the inside of the overflow trough 24. In addition, the flow and mixing of wastewater can cause tiny flocs to collide and combine with each other, forming larger flocs that are easier to settle. This dynamic environment is conducive to the growth and aggregation of flocs, thereby improving the mixing and sedimentation efficiency of wastewater and chemical reagents, and enabling more pollutants to be treated from the wastewater. refer to Figure 2 , Figure 3 and Figure 4As shown, when chemical treatment is required on the wastewater in the chemical treatment tank 1, the wastewater is discharged into the conical cylinder 21 and the limiting cylinder 26 through the wastewater inlet pipe 12. The wastewater then overflows from the opening inside the limiting cylinder 26 through the wastewater inlet pipe 12, and the limiting cylinder 26 blocks the wastewater discharged from the wastewater inlet pipe 12. The wastewater can only flow down along the inner wall of the limiting cylinder 26 and the outer wall of the wastewater inlet pipe 12. During this process, wastewater and impurities flow into the interior of the conical cylinder 21 and the bottom of the chemical treatment tank 1. At this time, the chemical treatment... As the wastewater inside the treatment tank 1 and the conical tube 21 increases, chemical reagents are then introduced into the treatment tank 1 and the conical tube 21. The chemical reagents mix and contact with the wastewater in the middle of the conical tube 21 and the treatment tank 1. During this process, most of the heavier particles fall down with the water flow to the lowest part of the treatment tank 1. As a result, after the conical tube 21 and the treatment tank 1 are full, the water continues to rise until it reaches the vicinity of the slow-flow component 3. Then, the wastewater overflows from the slow-flow component 3 and flows into the overflow tank 24. As the overflow tank 24 discharges the mixed wastewater from its interior through the outlet pipe 25, the wastewater fills the conical cylinder 21 and the chemical treatment tank 1. With the wastewater continuously supplied by the inlet pipe 12, the wastewater discharged from the opening of the inlet pipe 12 interacts with the wastewater inside the conical cylinder 21, causing the wastewater in the chemical treatment tank 1 and the conical cylinder 21 to reach saturation. Furthermore, the wastewater in the chemical treatment tank 1... The conical tube 21 has good fluidity, and the wastewater moves back and forth in sequence, causing the wastewater to move from top to bottom and then from bottom to top inside the waste inlet pipe 12, the limiting cylinder 26, and the conical tube 21. The wastewater flows slowly and travels a long distance during the flow process. As a result, the added wastewater and the wastewater mixed in the conical tube 21 are mutually dispersed and mixed with the chemical reagents again. The continuous water flow makes the water quality and treatment effect in the chemical treatment tank 1 more stable, reducing the impact of wastewater volume or water quality fluctuations on the treatment effect.

[0018] refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a perforated ring frame 27 is fixedly connected inside the chemical treatment tank 11. The perforated ring frame 27 is used to slow down the flow of wastewater and ensure that the wastewater is evenly dispersed in the chemical treatment tank 1. A limiting cylinder 26 is fixedly connected in the middle of the perforated ring frame 27. The bottom of the limiting cylinder 26 is located inside the conical tube 21 and is sleeved on the outside of the waste inlet pipe 12. When the wastewater level inside the chemical treatment tank 1 and the conical cylinder 21 overflows, wastewater is continuously supplied to the inside of the limiting cylinder 26 through the waste inlet pipe 12. At this time, the wastewater is guided by both the inner wall and the outer side of the limiting cylinder 26, and the wastewater is discharged at different positions inside the limiting cylinder 26. Moreover, the discharged wastewater interacts and disperses with the wastewater at different positions inside the chemical treatment tank 1. The wastewater in the chemical treatment tank 1 interweaves and interacts between the top and bottom of the perforated ring frame 27, so that the perforated ring frame 27 maintains a slow flow state for the wastewater in the chemical treatment tank 1 during circulation. Thus, the wastewater is in an interactive state, which is used to improve the water flow state, reduce the occurrence of short-circuiting phenomenon, and make the chemical treatment tank 1 better adapt to the fluctuation of water volume. When the water volume increases, the mixing effect can make the wastewater more evenly distributed in the chemical treatment tank 1, avoiding the impact of excessive local water volume on the sedimentation effect. This allows the wastewater to maintain sufficient contact with chemical reagents in the chemical treatment tank 1 and achieve particle sedimentation in the wastewater, thereby improving the treatment effect.

[0019] refer to Figure 3 , Figure 4 and Figure 5 As shown, the slow-flow assembly 3 includes an overflow weir ring 31 rotatably connected to the top of the centering ring 23 and a second toothed ring 34 rotatably connected to the side of the chemical treatment tank 1 near the centering ring 23. A first toothed ring 33 is fixedly connected to the side of the overflow weir ring 31 near the second toothed ring 34. A perforated ring plate 32 is fixedly connected inside the second toothed ring 34, and the perforated ring plate 32 is rotatably sleeved on the outside of the limiting cylinder 26. A gear 35 that meshes with the second toothed ring 34 and the first toothed ring 33 is also rotatably connected to one side of the centering ring 23. A first servo motor 36 is fixedly connected to the outside of the overflow ring 22, and the first servo motor 36 is used to drive the gear 35 to rotate. A sealing ring 37 is connected between the centering ring 23 and the overflow ring 22, and the sealing ring 37 is sleeved on the outside of the output end of the first servo motor 36. refer to Figure 3 , Figure 4 and Figure 5 As shown, when the water level inside the chemical treatment tank 1 overflows along the centering ring 23, the overflow weir ring 31 is used to block the overflowing wastewater near the centering ring 23, and to block the particulate impurities that float briefly in the wastewater, preventing the particulate impurities from being discharged simultaneously with the overflowing wastewater. After the overflowing wastewater is blocked by impurities, the particulate impurities form a temporary accumulation at the opening of the centering ring 23. During this process, the wastewater needs to pass through the particulate impurities and move closer to the overflow weir ring 31, which is beneficial for blocking the remaining fine impurities. This makes the water flow in the chemical treatment tank 1 and the centering ring 23 relatively more stable, further increasing the contact time between the wastewater and the chemical reagents in the chemical treatment tank 1, and improving the wastewater treatment efficiency. refer to Figure 3 , Figure 4 and Figure 5As shown, when wastewater is present near the overflow weir ring 31 and the perforated ring frame 27, the first servo motor 36 drives the gear 35 to rotate along one side of the centering ring 23, and the output end of the first servo motor 36 rotates inside the sealing ring 37. The gear 35 then rotates, causing the second gear ring 34 and the first gear ring 33 to mesh and rotate. At this time, the second gear ring 34 rotates along the top of the chemical treatment tank 1 and drives the perforated ring plate 32 to rotate synchronously, causing the perforated ring plate 32 to rotate along the top of the perforated ring frame 27. Consequently, the positions of the holes and blank spaces on the perforated ring plate 32 and the perforated ring frame 27 alternate, continuously adjusting the size of the perforations between the perforated ring plate 32 and the perforated ring frame 27. This is used to treat the wastewater at the bottom of the perforated ring frame 27 and the area near the intersection of the perforated ring plate 32 and the perforated ring frame 27. The wastewater is disturbed, and the continuous influx and mixing of the wastewater breaks the local static state, so that the wastewater and particulate impurities are evenly distributed throughout the chemical treatment tank 1 and the conical tube 21. This avoids excessive accumulation of local sediments, which would affect the normal operation of the chemical treatment tank 1 and ensure that the chemical reagents work evenly throughout the chemical treatment tank 1 and the conical tube 21. During this process, the rotation of the gear 35 drives the first toothed ring 33 and the overflow weir ring 31 to rotate along the top of the centering ring 23 and the second toothed ring 34. At this time, the rotation of the overflow weir ring 31 disturbs the particulate impurities trapped nearby, so that the particulate impurities and the wastewater remain in motion. This ensures that the particulate impurities can pass through the perforated ring frame 27 again and move into the conical tube 21 and the interior of the chemical treatment tank 1, further improving the treatment effect of the wastewater in the chemical treatment tank 1.

[0020] refer to Figure 4 and Figure 5 As shown, a number of support blocks 38 are fixedly connected to the top of the perforated ring plate 32, and one side of the support block 38 is attached to the outside of the limiting cylinder 26. A wedge block 39 is fixedly connected to the top of the support block 38, and the wedge block 39 is located inside the limiting cylinder 26. A guide frame 301 is fixedly connected to the side of the wedge block 39 away from the limiting cylinder 26, and the guide frame 301 and the wedge block 39 are combined to form an X-shaped structure. The number of support blocks 38 is 4, and the number of wedge blocks 39 and guide frames 301 is the same as the number of support blocks 38. The wedge blocks 39 and support blocks 38 are combined to form a Z-shaped structure, so that the wedge blocks 39 and support blocks 38 can process the inside and outside of the limiting cylinder 26 at the same time. Furthermore, the rotation of the perforated ring plate 32 causes the support block 38 to rotate along the outer wall of the limiting cylinder 26. Subsequently, the rotation of the support block 38 causes the wedge block 39 to rotate along the inner wall of the limiting cylinder 26. At this time, the rotation of the wedge block 39 causes the guide frame 301 to move along the inner circumference of the limiting cylinder 26, which can increase the turbulence in the wastewater near the limiting cylinder 26, prevent wastewater and particulate impurities from depositing and clogging at the opening of the limiting cylinder 26, maintain the continuous delivery of wastewater to the limiting cylinder 26, and enable the wastewater to contact the chemical reagent more quickly, thus accelerating the reaction process.

[0021] refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the diversion assembly 4 includes a stabilizing rod 41 fixedly connected to the bottom wall inside the chemical treatment tank 1 and a movable sleeve 42 slidably sleeved outside the stabilizing rod 41. The movable sleeve 42 is used for inserting and removing the bottom opening of the conical tube 21. Two symmetrical connecting rods 43 are fixedly connected to the outside of the movable sleeve 42, and a connecting sleeve 46 is movably connected to the top of the connecting rod 43. A guide column 44 is slidably sleeved inside the connecting sleeve 46. A power column 47 is rotatably connected to the inner wall of the chemical treatment tank 1. A curved block 45 is connected between the guide column 44 and the power column 47. A second servo motor 48 is fixedly connected to the outside of the chemical treatment tank 1, and the second servo motor 48 is used to drive the power column 47 to rotate. Furthermore, the number of connecting sleeves 46, guide pillars 44, curved blocks 45, and power pillars 47 are all equal to the number of two connecting rods 43, and they are used in pairs. Moreover, the second servo motor 48 is installed between one of the power pillars 47, so it can be known that there is one second servo motor 48. The connecting sleeves 46, guide pillars 44, curved blocks 45, power pillars 47, and connecting rods 43 are symmetrically and alternately arranged outside the moving sleeve 42. Therefore, the moving directions of the connecting sleeves 46, guide pillars 44, curved blocks 45, and power pillars 47 are different. The moving sleeve 42 moves up and down along the outside of the stabilizing rod 41 under the movement of the two connecting rods 43. At the same time, the contact surfaces of the connecting rods 43, connecting sleeves 46, and curved blocks 45 with wastewater and particles are all designed with a conical structure to avoid jamming between them. refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, when wastewater and particulate impurities settle between the chemical treatment tank 1 and the conical cylinder 21, the second servo motor 48 rotates, driving one of the power columns 47 to rotate synchronously. Then, the rotation of the power column 47 drives one of the curved blocks 45 to rotate synchronously. At this time, the rotation of the curved block 45 drives one of the guide columns 44 to move synchronously, and the rotation of the guide column 44 drives the connecting sleeve 46 to move upward or downward, and as... Figure 8 As shown, the two connecting sleeves 46 and the two connecting rods 43 are staggered and opposite to each other outside the movable sleeve 42. At this time, the movable sleeve 42 swings along the outside of the stabilizer rod 41 and moves upward, as shown in the figure. Figure 9 As shown, the two connecting rods 43 and the two connecting sleeves 46 are in a horizontal position outside the movable sleeve 42. At this time, the movable sleeve 42 swings along the outside of the stabilizing rod 41 and moves upward. Then, the top of the movable sleeve 42 is inserted into the bottom of the conical tube 21, and as shown... Figure 10 As shown, the two connecting sleeves 46 and the two connecting rods 43 are staggered and opposite to each other outside the movable sleeve 42. At this time, the movable sleeve 42 swings along the outside of the stabilizing rod 41 and moves downward. Then, the top of the movable sleeve 42 is pulled out from the bottom of the conical tube 21. This process is repeated in sequence. This not only loosens the particulate impurities at the bottom of the conical tube 21, but also allows the particulate impurities and wastewater to flow in multiple dimensions in the chemical treatment tank 1 and the conical tube 21. This ensures that the particulate impurities and wastewater maintain sufficient contact with the chemical reagents, improves the reaction efficiency of the wastewater, and is conducive to the full sedimentation of the wastewater.

[0022] A method for treating water in an electroplating solution using a water treatment device includes the following steps: S1. The wastewater is connected to the external wastewater discharge pipe through the wastewater inlet pipe 12. Then the wastewater inlet pipe 12 guides the wastewater into the interior of the chemical treatment tank 1. At this time, the wastewater is added into the interior of the chemical treatment tank 1 and the wastewater is mixed with the chemical reagents inside the chemical treatment tank 1 to chemically precipitate the particulate impurities in the wastewater. S2. Secondly, during the process of the wastewater being guided into the chemical treatment tank 1 by the wastewater inlet pipe 12, the treatment component 2 is used to guide the wastewater output from the wastewater inlet pipe 12. At this time, the wastewater moves from bottom to top in the treatment component 2, and then the wastewater flows into the conical tube 21 in the treatment component 2 according to inertia. The conical tube 21 guides the wastewater into the chemical treatment tank 1, and the wastewater flows in a throat-like manner between the conical tube 21 and the chemical treatment tank 1, so that there is enough contact time between it and the chemical reagents, thereby forming a sediment in the wastewater between the conical tube 21 and the chemical treatment tank 1. S3. Next, the waste inlet pipe 12 continuously pours wastewater into the conical cylinder 21 and the chemical treatment tank 1. Then, the wastewater inside the conical cylinder 21 and the chemical treatment tank 1 is full, and the wastewater overflows outward along the inside of the limiting cylinder 26. At this time, the limiting cylinder 26 discharges the wastewater in the chemical treatment tank 1 from different directions, so that the wastewater is further dispersed in the conical cylinder 21 and the chemical treatment tank 1. The wastewater inside the chemical treatment tank 1 overflows from the top of the chemical treatment tank 1, so that the wastewater mixed with the chemical reagent is discharged outward. Moreover, the waste inlet pipe 12 keeps the wastewater inside the conical cylinder 21 in a flowing state, so that the continuous wastewater interacts with the chemical reagent and the overflowing wastewater in the conical cylinder 21 and the chemical treatment tank 1, further improving the contact between the wastewater and the chemical reagent. S4. The slow-flow component 3 is used to block the overflow of wastewater between the treatment component 2 and the chemical treatment tank 1, and to intercept the particles that float briefly in the wastewater, so that the particles in the wastewater can settle fully in the chemical treatment tank 1 and the conical tube 21. S5. Subsequently, the diversion component 4 is used to slightly and multidimensionally ripple the wastewater and particles between the chemical treatment tank 1 and the conical tube 21. Then, the wastewater and particles continue to flow. At this time, the chemical reagents are in full contact with the wastewater in the chemical treatment tank 1 and the conical tube 21, thereby improving the wastewater treatment quality.

[0023] Working principle: When using; refer to Figure 1 , Figure 2 and Figure 3 As shown, the wastewater is connected to the external wastewater discharge pipe through the wastewater inlet pipe 12. The wastewater inlet pipe 12 then guides the wastewater into the interior of the chemical treatment tank 1. At this time, the wastewater is added into the interior of the chemical treatment tank 1 and mixed with the chemical reagents inside the chemical treatment tank 1 to chemically precipitate the particulate impurities in the wastewater.

[0024] refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, wastewater overflows from the opening inside the constricting cylinder 26 of the waste inlet pipe 12, and the constricting cylinder 26 blocks the wastewater discharged from the waste inlet pipe 12. The wastewater can only flow down along the inner wall of the constricting cylinder 26 and the outer wall of the waste inlet pipe 12. During this process, wastewater and impurities flow into the interior of the conical tube 21 and the bottom of the chemical treatment tank 1. At this time, the wastewater inside the chemical treatment tank 1 and the conical tube 21 is constantly increasing. Then, chemical reagents are put into the chemical treatment tank 1 and the conical tube 21. The chemical reagents mix and contact with the wastewater in the middle of the conical tube 21 and the chemical treatment tank 1. During this process, most of the heavier particles have already fallen down with the water flow to the lowest part of the chemical treatment tank 1. So after the conical tube 21 and the chemical treatment tank 1 are full, the water continues to rise until it reaches the vicinity of the slow flow component 3.

[0025] refer to Figure 4 and Figure 5 As shown, the slow-flow component 3 is used to block the overflow of wastewater near the centering ring 23 and the chemical treatment tank 1. Particulate impurities form a temporary accumulation at the opening of the centering ring 23. During this process, the wastewater needs to pass through the particulate impurities and move closer to the slow-flow component 3, which is beneficial for blocking the remaining fine impurities and makes the water flow at the chemical treatment tank 1 and the centering ring 23 relatively more stable.

[0026] refer to Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, the wastewater in the chemical treatment tank 1 and the conical cylinder 21 is saturated. When the wastewater flows in the chemical treatment tank 1 and the conical cylinder 21, the reciprocating movement of the diversion component 4 can not only loosen the particulate impurities at the bottom of the conical cylinder 21, but also allow the particulate impurities and wastewater to flow in multiple dimensions in the chemical treatment tank 1 and the conical cylinder 21. This ensures that the particulate impurities and wastewater are in full contact with the chemical reagents, improves the reaction efficiency of the wastewater, and is conducive to the full sedimentation of the wastewater.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

5. The treatment method for a water treatment device for electroplating solution according to claim 4, characterized in that, Includes the following steps: S1. The wastewater is connected to the external wastewater discharge pipe through the wastewater inlet pipe. The wastewater inlet pipe then guides the wastewater into the interior of the chemical treatment tank. At this time, the wastewater is added into the interior of the chemical treatment tank and mixed with the chemical reagents inside the chemical treatment tank to chemically precipitate the particulate impurities in the wastewater. S2. Secondly, during the process of the wastewater being guided into the chemical treatment tank by the wastewater inlet pipe, the treatment component is used to guide the wastewater output from the wastewater inlet pipe. At this time, the wastewater moves from bottom to top in the treatment component. Then, the wastewater flows into the conical tube in the treatment component due to inertia. The conical tube guides the wastewater into the chemical treatment tank. Moreover, the wastewater flows in a throat-like manner between the conical tube and the chemical treatment tank, allowing sufficient contact time between it and the chemical reagents. As a result, the wastewater forms sediment between the conical tube and the chemical treatment tank. S3. Next, the waste inlet pipe continuously draws wastewater into the conical cylinder and the chemical treatment tank. Soon, the conical cylinder and the chemical treatment tank are full of wastewater, and the wastewater overflows outward along the inside of the limiting cylinder. At this time, the limiting cylinder discharges wastewater from different directions in the chemical treatment tank, which further disperses the wastewater in the conical cylinder and the chemical treatment tank. The wastewater inside the chemical treatment tank overflows from the top of the chemical treatment tank, allowing the wastewater mixed with chemical reagents to be discharged outward. Moreover, the waste inlet pipe keeps the wastewater inside the conical cylinder in a flowing state, so that the continuous wastewater interacts with the chemical reagents and the overflowing wastewater in the conical cylinder and the chemical treatment tank, further improving the contact between the wastewater and the chemical reagents. S4. The flow-retarding component is used to block the overflow of wastewater between the treatment component and the chemical treatment tank, and to intercept the particles that float briefly in the wastewater, so that the particles in the wastewater can settle fully in the chemical treatment tank and the conical tube. S5. Subsequently, the diversion component is used to create slight multidimensional fluctuations in the wastewater and particles between the chemical treatment tank and the conical tube. The wastewater and particles then maintain flow, and the chemical reagents are in full contact with the wastewater in the chemical treatment tank and the conical tube, thereby improving the wastewater treatment quality.
