Description

Technical Field

[0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a comprehensive recovery and treatment device for treating copper-containing wastewater produced in the production of copper-clad ceramic substrates. Background Art

[0002] The comprehensive recovery and treatment device for treating copper-containing wastewater generated during the production of copper-clad ceramic substrates is designed to achieve copper resource recovery and reuse in wastewater through a series of advanced treatment technologies. This device focuses on the efficient removal of harmful substances in wastewater while ensuring the effective recovery of copper elements to reduce environmental impact and support sustainable development. By optimizing the treatment process, the system can significantly reduce the heavy metal content in wastewater discharge to meet the requirements of environmental protection regulations. At the same time, it also provides manufacturers with a valuable way to recover metal resources, promoting the recycling of resources and improving economic benefits.

[0003] The prior art still has the following deficiencies:

[0004] Existing wastewater treatment equipment has difficulty in treating fine particles. The copper sulfide particles generated by the sulfide precipitation method are small and difficult to settle and separate, which brings challenges to subsequent treatment. In order to save costs, existing industrial inclined plate sedimentation tanks use a large number of plastic materials as inclined plates, and are installed by manual melt welding at the construction site. The inclination angle of the inclined plate cannot be adjusted. At the same time, after long-term use, if the sediment on the inclined plate is not cleaned in time, it will gradually accumulate to form a thick layer, which not only increases the head loss, but also may block the channels between the inclined plates, reducing the effective sedimentation area, thereby reducing the working efficiency of the sedimentation tank. In addition, when a problem occurs with a single inclined plate, because it is an integral installation, it is difficult to replace or repair the inclined plate in a specific area, which usually requires a large workload, and sometimes the entire sedimentation tank must be emptied for maintenance work.

[0005] Before treating the wastewater produced by copper-clad ceramic substrates, the pH value of the wastewater needs to be adjusted to an appropriate range to facilitate subsequent chemical reactions. The existing adjustment method is generally achieved by artificially adding alkaline substances, such as sodium hydroxide. However, the problem is that when adjusting the pH, due to the large amount of wastewater, how to ensure that the wastewater and the alkaline substance react quickly and fully, and how to judge whether to continue to add alkaline substances when it is not determined whether the reaction is sufficient. These problems have brought troubles to the pH value adjustment. Usually, in order to avoid the wastewater being too acidic, a large amount of alkaline substances are added to ensure its sufficient reaction, but this also lays the groundwork for the disadvantage of high cost of wastewater treatment.

[0006] When the wastewater from the production of copper-clad ceramic substrates is sulfidized, the deposited copper sulfide sludge needs to be desilted from time to time. The existing device mainly opens grooves at the bottom of the pool and uses the flow of water to drive the sludge out. Although this method is simple and efficient, the problem is that when the water flow rate exceeds the threshold, the deposited copper sulfide particles will be re-dispersed in the wastewater due to resuspension. In addition, the presence of water flow changes the flow state inside the water body, thereby affecting the movement trajectory of the particles. If the water flow direction is uneven or there are eddies, the sedimentation path of the particles will become complicated, which may increase the probability of collision, but it may also cause some particles to deviate from the ideal sedimentation route, prolong the sedimentation time or even fail to settle normally. Summary of the invention

The copper-containing wastewater to be treated is discharged into the pretreatment tank 1 through the feed port 2. The untreated copper-containing wastewater is acidic and needs to be pH-adjusted. Sodium sulfide needs to be added to the wastewater after adjustment for sulfidation, and divalent copper ions react with it to produce copper sulfide precipitates that are insoluble in water, and the wastewater can be discharged through the liquid outlet pump 6;

The control module is connected to the detection module by signal, the control module is connected to the pH sensor 12 by signal, and the detection module is connected to the first servo motor 13 by signal. An alkali solution regulating box 8 is provided in the pretreatment tank 1, and the pH value in the pretreatment tank 1 is detected in real time by the pH sensor 12. The first servo motor 13 is controlled by the signal processing function of the control box 3. When the first servo motor 13 drives the first threaded rod 9 to rotate, the piston plate 10 will press out the alkaline solution in the alkali solution regulating box 8, and at the same time, the rotation of the stirring blade 5 will make the alkali solution and the wastewater solution react quickly, so that the pH value of the wastewater in the pretreatment tank 1 is quickly stabilized, so that the amount of alkali solution added can be controlled to be kept within a suitable range, which not only ensures the need for adjusting the pH value of the wastewater, but also avoids the waste of alkali solution materials;

[0036] The sulfide sedimentation tank 14 is fixedly connected to one side of the pretreatment tank 1. Six adjustable mounting frame plates 16 are rotatably connected in the sulfide sedimentation tank 14. A corrugated sedimentation plate 17 is slidably connected in the adjustable mounting frame plate 16. Both sides of the sulfide sedimentation tank 14 are provided with a linkage shell 18. A linkage mechanism is provided in the linkage shell 18. An inclined mud guide plate 19 is fixedly connected to the inner bottom of the sulfide sedimentation tank 14. A plurality of arc-shaped matching plates 21 are slidably connected to the inclined mud guide plate 19. Two adjacent arc-shaped matching plates 21 are fixedly connected by steel bars.

The matching angle plate 22 is fixedly connected to one side of the arc-shaped matching plate 21 close to the pretreatment tank 1. The plate 22 is provided with threaded holes, and the inclined mud guide plate 19 is equipped with two sets of servo motors. The output end of the servo motor is coaxially fixedly connected with a No. 2 threaded rod 23, and the No. 2 threaded rod 23 penetrates the matching angle plate 22 on the corresponding side and is threadedly connected thereto. A plurality of mud discharge ports 24 are provided on one side of the sulfide sedimentation tank 14, and the opening position of the mud discharge port 24 corresponds to the position of the inclined mud guide plate 19. The wastewater treated by the pretreatment tank 1 is discharged into the sulfide sedimentation tank 14. According to the principle of shallow sedimentation, the larger the sedimentation area, the shorter the sedimentation time, and the higher the sedimentation efficiency. By setting a plurality of adjustable mounting frame plates 16, when installing the corrugated sedimentation plate 17, the corrugated sedimentation plate 17 can be directly inserted for use. It is also more convenient for maintenance and replacement in the later stage. It is not necessary to replace all the corrugated sedimentation plates 17 in the sulfide sedimentation tank 14. In addition, by setting a linkage mechanism, the angle of the corrugated sedimentation plate 17 is adjustable, so that the sludge deposited on the corrugated sedimentation plate 17 can be quickly discharged by adjusting the angle of the corrugated sedimentation plate 17, which can avoid head loss, and can also avoid excessive load on the corrugated sedimentation plate 17 caused by sediment accumulation, and a reduction in effective sedimentation area caused by excessively thick sedimentation layers. By setting an inclined mud guide plate 19 at the bottom of the sulfide sedimentation tank 14, the sludge falling from the corrugated sedimentation plate 17 will naturally fall on the inclined mud guide plate 19, and the sludge will gradually move toward the mud discharge through the action of gravity. The sludge outlet 24 moves to one side, but after a large amount of sludge is accumulated, it needs to be discharged in a centralized manner. The built-in servo motor of the inclined mud guide plate 19 drives the second threaded rod 23 to rotate, so that the matching angle plate 22 threadedly connected to the second threaded rod 23 drives the multiple arc-shaped matching plates 21 to move. When the arc-shaped matching plate 21 and the notch on the inclined mud guide plate 19 are matched, the mud outlet is opened. At this time, the sludge discharge can avoid the influence of the sludge moving in the sulfide sedimentation tank 14 to the greatest extent. The negative pressure generated by the sludge discharge will be concentrated on the end of the inclined mud guide plate 19 close to the mud outlet 24. The water flow rate will accelerate the sludge discharge without affecting the distribution of copper sulfide particles, so that the sludge discharge speed is accelerated;

The bottom of the wheel 15 is coaxially fixedly connected to a rotating disk 7, and a swing arm 4 is rotatably connected to the rotating disk 7 away from the axis position. The swing arm 4 is rotatably connected to the combined frame plate 32 at one end away from the rotating disk 7. The purpose of setting the linkage mechanism is to make the corrugated sedimentation plate 17 vibrate while adjusting the angle of the corrugated sedimentation plate 17 when removing the sludge on the corrugated sedimentation plate 17, so that the sludge attached to the corrugated sedimentation plate 17 can fall more quickly, thereby improving the sludge treatment efficiency. The second servo motor 20 can drive the active bevel gear 15 and the rotating disk 7 to rotate. The rotation of the active bevel gear 15 will cause the driven bevel gear 38 meshing with it to rotate, so that the secondary gear 34 will rotate, and the main gear 3 meshing with it will rotate. 3 will rotate, the worm 27 coaxially fixedly connected to the main gear 33 will rotate, and the worm wheel 30 meshing with it will drive the adjustable mounting frame plate 16 to rotate, so that the angle of the corrugated sedimentation plate 17 in the adjustable mounting frame plate 16 can be adjusted. At the same time, due to the rotation of the rotating disk 7, the swing arm 4 will make the combined frame plate 32 and the worm 27 vibrate at a high speed as a whole, and the worm wheel 30 meshing with the worm 27, the adjustable mounting frame plate 16 and the corrugated sedimentation plate 17 will vibrate synchronously. In order to avoid the separation between the active bevel gear 15 and the driven bevel gear 38, a matching sleeve 36 and a limiting sleeve 35 are provided on one side of the driven bevel gear 38. Through the setting of the buffer spring 37, the driven bevel gear 38 will always fit the active bevel gear 15 and mesh with it.The arrangement of the bearing 28 and the annular bushing 29 can create a certain virtual position between the rotating shaft of the adjustable mounting frame plate 16 and the sulfide sedimentation tank 14, so that the service life of the rotating shaft of the adjustable mounting frame plate 16 can be protected when the adjustable mounting frame plate 16 vibrates.

[0038] The working principle of the present invention is:

[0039] The copper-containing wastewater to be treated is discharged into the pretreatment tank 1 through the feed port 2. The untreated copper-containing wastewater is acidic and needs to be pH-adjusted. Sodium sulfide is added to the adjusted wastewater for sulfidation. The divalent copper ions react with it to produce copper sulfide precipitates that are insoluble in water. The wastewater can be discharged through the liquid outlet pump 6.

[0040] The signal processing function of the control box 3 is used to control the No. 1 servo motor 13. When the No. 1 servo motor 13 drives the No. 1 threaded rod 9 to rotate, the piston plate 10 will press out the alkaline solution in the alkali solution regulating box 8. At the same time, the rotation of the stirring blade 5 will cause the alkali solution and the wastewater solution to react rapidly, thereby quickly stabilizing the pH value of the wastewater in the pretreatment tank 1. In this way, the amount of alkali solution can be controlled to be kept within a suitable range, which not only ensures the need for adjusting the pH value of the wastewater, but also avoids the waste of alkali solution materials.

[0041] The wastewater treated by the pretreatment tank 1 is discharged into the sulfide sedimentation tank 14. According to the principle of shallow sedimentation, the larger the sedimentation area, the shorter the sedimentation time and the higher the sedimentation efficiency. By setting a plurality of adjustable mounting frames 16, when installing the corrugated sedimentation plate 17, the corrugated sedimentation plate 17 can be directly inserted for use. It is also more convenient for later maintenance and replacement, and there is no need to replace all the corrugated sedimentation plates 17 in the sulfide sedimentation tank 14. In addition, by setting a linkage mechanism, the angle of the corrugated sedimentation plate 17 is adjustable, so that the sludge deposited on the corrugated sedimentation plate 17 can be quickly discharged by adjusting the angle of the corrugated sedimentation plate 17, which can avoid head loss, and can also avoid excessive load of the corrugated sedimentation plate 17 caused by sedimentation accumulation, and reduction of effective sedimentation area caused by excessively thick sedimentation layer. By setting an inclined The mud guide plate 19 is placed, and the sludge falling from the corrugated sedimentation plate 17 will naturally fall on the inclined mud guide plate 19. Through the action of gravity, the sludge will gradually move to the side of the mud discharge port 24. However, after a large amount of sludge is accumulated, it needs to be discharged in a centralized manner. The built-in servo motor of the inclined mud guide plate 19 drives the No. 2 threaded rod 23 to rotate, so that the matching angle plate 22 threadedly connected with the No. 2 threaded rod 23 can drive the multiple arc-shaped matching plates 21 to move. When the arc-shaped matching plate 21 is matched with the notch on the inclined mud guide plate 19, the mud discharge port is opened. At this time, the sludge discharge can avoid the influence of the sludge moving in the sulfide sedimentation tank 14 to the greatest extent. The negative pressure generated by the sludge discharge will be concentrated on the end of the inclined mud guide plate 19 close to the mud discharge port 24. The water flow rate will accelerate the sludge discharge without affecting the distribution of copper sulfide particles, so that the sludge discharge speed is accelerated;

[0042] The purpose of setting the linkage mechanism is to make the corrugated sedimentation plate 17 vibrate while adjusting the angle of the corrugated sedimentation plate 17 when removing the sludge on the corrugated sedimentation plate 17, so that the sludge attached to the corrugated sedimentation plate 17 can fall more quickly, thereby improving the sludge treatment efficiency. The second servo motor 20 can drive the active bevel gear 15 and the rotating disk 7 to rotate. The rotation of the active bevel gear 15 will cause the driven bevel gear 38 meshing with it to rotate, then the sub-gear 34 will rotate, the main gear 33 meshing with it will rotate, and the worm 27 coaxially fixedly connected to the main gear 33 will rotate, and the worm 27 coaxially fixedly connected to the main gear 33 will rotate. The meshed worm gear 30 will drive the adjustable mounting frame plate 16 to rotate, so that the angle of the corrugated sedimentation plate 17 in the adjustable mounting frame plate 16 can be adjusted. At the same time, due to the rotation of the rotating disk 7, the swing arm 4 will cause the combined frame plate 32 and the worm 27 to vibrate at high speed as a whole, and the worm gear 30, the adjustable mounting frame plate 16 and the corrugated sedimentation plate 17 meshed with the worm 27 will vibrate synchronously. In order to avoid the disengagement between the active bevel gear 15 and the driven bevel gear 38, a matching sleeve 36 and a limiting sleeve 35 are provided on one side of the driven bevel gear 38. Through the setting of the buffer spring 37, the driven bevel gear 38 will always fit the active bevel gear 15 and mesh with it.
