Description

Technical Field

[0001] The present invention relates to the technical field of heavy metal wastewater treatment, and particularly relates to a multi-stage recovery treatment device for copper-containing wastewater. Background Art

[0002] Existing multi-stage recovery treatment devices for copper-containing wastewater are important devices in the field of industrial wastewater treatment for treating copper-containing wastewater and realizing the recovery of copper resources. Such devices generally have multiple treatment units, with each unit having a clear division of labor and cooperating with each other. The devices usually have a solid outer shell, and the internal structure is precise and complex, including various components such as pipelines, reaction vessels, and control systems. The pipelines are responsible for transporting wastewater and treatment agents, guiding the wastewater to each treatment unit in an orderly manner. The reaction vessels provide a reaction site for wastewater treatment to ensure the smooth progress of various treatment operations. The control system is the "brain" of the entire device, which can accurately adjust operating parameters such as temperature, pressure, and flow rate to ensure that the device operates in the best state. Moreover, to meet the needs of industrial production of different scales, the devices are diverse in specifications. Small devices are suitable for laboratories or small-scale enterprises, while large devices can meet the treatment requirements of a large amount of copper-containing wastewater generated by large-scale industrial production. With such a design and configuration, the multi-stage recovery treatment device for copper-containing wastewater can stably treat copper-containing wastewater and realize the recovery and utilization of copper resources, playing an indispensable role in the sustainable development of industry.

[0003] Existing multi-stage recovery treatment devices for copper-containing wastewater are key facilities for ensuring water resource recycling and environmental protection. In small-scale production, these devices usually adopt a combination of various technologies such as chemical precipitation, ion exchange, and electrolysis to achieve efficient copper recovery and wastewater purification. The chemical precipitation method uses a precipitant to form a precipitate of copper, but the dosage of the precipitant is difficult to accurately control, which is likely to cause secondary pollution, and the subsequent sludge treatment cost is relatively high. The ion exchange method uses ion exchange resin to adsorb copper, but the resin is easily interfered by other impurities, and the exchange capacity is limited, requiring frequent regeneration or replacement. The electrolysis method can obtain high-purity copper, but the energy consumption is huge, the electrode material is consumed quickly, and the cost is high. In addition, the connection between the various links of the multi-stage treatment device is not tight enough, the treatment efficiency needs to be improved, and the device is prone to blockage and corrosion, with high maintenance costs and high technical requirements for operators, seriously affecting the treatment efficiency, difficult to meet the needs of laboratories, small enterprises, etc. for rapid wastewater treatment, and also limiting the treatment effect and application range of the device, bringing certain adverse effects to the usage process.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, the copper concentration of the wastewater is monitored in real time by the detection probe. The first servo motor is accurately regulated by the control system to achieve precise control of the feeding amount of the precipitant. The cooperation of the threaded rod and the threaded slider, and the piston structure formed by the pressing rod and the pressing bin ensure that the feeding error is extremely small. This process ensures that the appropriate amount of precipitant enters the reaction tank, making the initial conditions of wastewater treatment stable. The precise feeding control avoids the problems caused by too much or too little precipitant, preventing both the waste of the reagent and secondary pollution, and ensuring the efficient progress of the subsequent treatment process, laying a good foundation for the entire copper-containing wastewater treatment process and improving the stability and reliability of the treatment effect.

[0017] 2. In the present invention, the first servo motor drives the threaded rod to rotate, enabling the second placement cover to be in place. The third servo motor drives the electrolyzer to swing, and the electrolyzer undergoes an electrolysis reaction during the swinging process. This not only efficiently precipitates copper but also enhances the reaction efficiency through the stirring effect. Its swinging makes the distribution of copper in the electrolysis area more uniform, increasing the contact opportunity with the electrodes and significantly improving the copper recovery amount. This design effectively improves the copper recovery rate, reduces the copper residue in the wastewater, realizes the efficient recovery of copper resources while reducing the subsequent treatment pressure, improves the treatment capacity of the equipment for copper-containing wastewater, and brings better economic and environmental benefits to the treatment of copper-containing wastewater.

[0018] 3. In the present invention, driven by the fourth servo motor, through the transmission of the third bevel gear and the fourth bevel gear, and in cooperation with structures such as the fifth servo motor, the effective collection of large-particle impurities in the wastewater is realized. The second sliding rod drives the lower cover plate and the upper cover plate to swing, and their tilt angle and swing amplitude can be flexibly adjusted to accurately intercept large-particle impurities in the wastewater. This process effectively prevents large-particle impurities from entering the subsequent treatment equipment, reduces the risk of equipment blockage and damage, extends the service life of the equipment, reduces the equipment maintenance cost. At the same time, it ensures the smooth progress of the subsequent treatment process, improves the overall treatment efficiency and treatment quality.

[0019] 4. In the present invention, the treated wastewater is pumped into the high-pressure tank, pressurized by the high-pressure pump, and the reverse osmosis membrane is used to achieve the efficient separation of water and impurities such as copper. The reverse osmosis membrane intercepts the concentrated liquid and makes it flow back to the reaction tank for cyclic treatment, greatly improving the copper recovery efficiency and reducing the waste of copper resources. At the same time, the clear water passing through the reverse osmosis membrane can meet the requirements of higher-standard discharge or reuse, reducing the environmental pollution caused by wastewater discharge, realizing the recycling of water resources, and having significant benefits in terms of environmental protection and resource utilization, conforming to the concept of sustainable development and enhancing the comprehensive value of the treatment of copper-containing wastewater.

[0041] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0042] Example 1, as Figures 1-6 shown, the wastewater treated by the pretreatment structure 4 enters the reaction tank 25 through the first water pump 42. The detection probe 225 is installed on the lower side of one end of the first slider 223. As the deflection column 228 rotates, the first slider 223 slides in the first chute 221 opened on one side of the vertical frame 220. As the wastewater enters, the detection probe 225 will gradually immerse into the wastewater to detect the concentration of copper in the wastewater in real time. A concentration detector is provided at the end of the detection probe 225 away from the first slider 223. The detector transmits the signal to the controller of the device through a wire. After receiving the signal, the controller will analyze the data and start the first servo motor 21 according to the concentration standard to adjust the rotation speed and angle of the threaded rod 24, so as to further control the feeding amount and ensure that the concentration of the wastewater entering the reaction tank 25 is always within a suitable range, providing stable raw material conditions for subsequent treatment processes;

[0043] The first servo motor 21 is energized and operates to drive the first bevel gear 22 to rotate. The first bevel gear 22 meshes with the second bevel gear 23, driving the second bevel gear 23 to rotate, and further driving the threaded rod 24 fixedly connected to the axis of the second bevel gear 23 to rotate synchronously. Since the threaded rod 24 is threadedly connected to the threaded slider 27, and the first limiting post 28 on the outer wall of the threaded slider 27 slides in the inverted L-shaped limiting groove 212 opened on the outer wall of the fixed sleeve 26, this restricts the threaded slider 27 to move only in a straight line along the limiting groove 212. As the threaded rod 24 rotates, the threaded slider 27 realizes a stable linear displacement under the constraint of the limiting groove 212. The movement of the threaded slider 27 is transmitted to the support base 29 through the first limiting post 28, thereby driving the sliding sleeve 210 to slide up and down along the outer wall of the fixed sleeve 26. And when the threaded slider 27 slides to the top in the limiting groove 212, it will drive the support base 29 and its connecting structure to deflect in the limiting groove 212, realizing the movement of the first extension frame 211 and its connected components to the upper part of the reaction tank 25. Then, continue to rotate. Since the first placement cover 218 is equal to the reaction tank 25, while realizing the pressing of the first extension frame 211 on the first buffer spring 219, the pressing rod 216 fixedly installed near the lower end of the storage tank 213 of the first extension frame 211 will also move along with the sliding sleeve 210. The pressing rod 216 and the pressing bin 215 are closely matched to form a piston structure. During the movement of the sliding sleeve 210, the pressing rod 216 makes a synchronous movement in the pressing bin 215. By precisely controlling the stroke and speed of the pressing rod 216, the feeding amount of the precipitant each time can be accurately adjusted, realizing the precise control of the feeding process.

[0044] Embodiment 2, as Figures 7-9As shown, when the first extension frame 211 is squeezed to allow a suitable precipitant to enter the reaction box 25, the first servo motor 21 is started, driving the first bevel gear 22 to rotate in the opposite direction, the first bevel gear 22 and the second bevel gear 23 are meshed with each other, and the power is transmitted to the second bevel gear 23, thereby driving the threaded rod 24 fixedly connected to the axis of the second bevel gear 23 to rotate synchronously, so as to move the second placement cover 33 to the upper side of the reaction box 25. After the third servo motor 34 is started, its rotor drives the first synchronous wheel 35 to rotate, and the first synchronous wheel 35 is connected to the second synchronous wheel 37 through a transmission belt to realize power transmission. The second synchronous wheel 37 also rotates synchronously. A toggle rod 36 is fixedly installed at the axis center of one side of the first synchronous wheel 35 away from the third servo motor 34. When the first synchronous wheel 35 rotates, the toggle rod 36 performs a circular motion accordingly. A fourth slide groove 314 is provided on the outer wall of the deflection block 313 rotatably installed at the axis center of the upper side of the second placement cover 33. The toggle rod 36 slides in the fourth slide groove 314. Due to the special shape of the fourth slide groove 314 and the circular motion of the toggle rod 36, the toggle rod 36 pushes the deflection block 313 to perform periodic rotation around its axis center during the sliding process in the fourth slide groove 314. The second synchronous wheel 37 is far away from the third servo motor 34. A first cam block 38 is detachably mounted on the axis of one side away from the connecting block 32. The first cam block 38 rotates with the second synchronous wheel 37. The arc groove 310 provided in the arc frame 39 is adapted to the first cam block 38. The end of the first cam block 38 away from the second synchronous wheel 37 slides in the arc groove 310. As the first cam block 38 rotates, its position in the arc groove 310 changes continuously, thereby pushing the rotating ring 311 and the first sliding rod 312 fixedly connected thereto to move up and down. A swing frame 316 is fixedly mounted on the lower end of the first sliding rod 312. When the first sliding rod 312 moves up and down, the swing frame 316 The movable frame 316 will swing periodically around the connection point between it and the first sliding rod 312. Electrolyzers 315 are installed at both ends of the swing frame 316. Therefore, the electrolyzer 315 will swing periodically in the wastewater as the swing frame 316 swings. In the process of the swing frame 316 driving the electrolyzer 315 to swing, the electrolyzer 315 is connected to an external power supply. Through the action of electric current, an electrolysis reaction occurs in the wastewater, thereby realizing the precipitation and recovery of copper. At the same time, the swing of the electrolyzer 315 plays a role in stirring the wastewater, so that the copper in the wastewater can be more evenly distributed in the electrolysis area, effectively enhancing the efficiency of the electrolysis reaction.

[0045] Embodiment three, as Figures 10-14As shown in the figure, when the untreated wastewater enters the treatment tank 44, after the fourth servo motor 45 is started, its rotor drives the third bevel gear 46 to reciprocate and deflect. The third bevel gear 46 meshes with the fourth bevel gear 47 to transmit power to the fourth bevel gear 47. A second sliding rod 48 is slidably installed at the axis of the fourth bevel gear 47. When the fourth bevel gear 47 rotates, three clamping columns 417 are fixedly installed at equal intervals on the lower side of the second sliding rod 48. The clamping columns 417 are connected to the lower cover plate 420 through a universal joint 418. The upper cover plate 419 is rotatably installed on the upper side of the lower cover plate 420. Three slots 427 are opened at equal intervals on the same side of the upper cover plate 419 and the lower cover plate 420. A pin 422 is arranged in the slot 427. The relative positions of the upper cover plate 419 and the lower cover plate 420 can be fixed by inserting and pulling out the pin 422. During the swinging process of the fourth bevel gear 47, the second swinging rod 412 can be driven to swing by the fifth servo motor 411, and then the third cam block 414 can be driven to swing through the second swinging rod 412, and then the swinging amplitude of the first swinging rod 49 can be driven through the third cam block 414. Through the swinging amplitude of the first swinging rod 49, the second sliding rod 48 is raised and lowered. When the second sliding rod 48 rises, the universal joint 418 will push the lower cover plate 420 to deflect and change from horizontal to inclined placement. During this process, the lower cover plate 420 and the upper cover plate 419 are driven to continuously swing by the fourth bevel gear 47 to collect larger particulate impurities in the wastewater, effectively removing the large particulate impurities in the wastewater and preventing these impurities from clogging or damaging the subsequent treatment equipment.

[0046] Example 4, as Figures 15-16 shown in the figure, the treated wastewater is pumped into the high-pressure tank 54 by the second water pump 52 through the second infusion pipe 51. The high-pressure pump 55 is installed on one side of the fourth placement cover 56. After starting, it pressurizes the wastewater in the high-pressure tank 54. Under the action of pressure, the water molecules in the wastewater pass through the reverse osmosis membrane 57 arranged in the middle of the lower side of the fourth placement cover 56, while impurities such as copper are intercepted by the reverse osmosis membrane 57. The concentrated liquid intercepted by the reverse osmosis membrane 57 contains a high concentration of copper and other impurities, and is returned to the reaction tank 25 through a pipeline and enters the treatment process again for cyclic treatment. This design improves the recovery efficiency of copper and reduces the wastewater discharge.
