Description

Technical Field

[0001] The present invention relates to the technical field of waste liquid purification, and in particular to an electrophoresis processing waste liquid purification system. Background Art

[0002] Electrophoretic coating is a key step in treating the surface of spare parts during processing. During this process, a coating film is formed on the surface of the spare parts, which can effectively improve the corrosion resistance of the spare parts and play a protective role. However, electrophoretic coating inevitably produces electrophoretic wastewater. Because the composition of electrophoretic wastewater is extremely complex and contains a variety of harmful substances, it must be treated with a dedicated wastewater purification device; however, the existing wastewater purification devices still have the following problems during use:

[0003] For example, the Chinese patent with publication number CN119306350A discloses a multi-stage electrophoretic wastewater treatment device, which includes an outer box body and a display screen installed on the front side of the outer box body; three sets of conveying pump bodies are installed inside the lower part of the outer box body, a preliminary treatment chamber is installed through the upper left side of the outer box body, a grid body with a circular ring-shaped structure is installed in the preliminary treatment chamber, a preliminary treatment chamber is installed above the sedimentation treatment chamber, and a dissolved air release mechanism is installed on the corresponding outer box body above the flotation treatment chamber; an activated carbon adsorption plate is installed in the adsorption treatment chamber; a lower support plate is installed through the upper outer side of the guide tube; and a rotating rod is symmetrically installed on the outer side of the lower end of the lower medicine tube. This multi-stage electrophoretic wastewater treatment device facilitates multi-stage filtration treatment of electrophoretic wastewater, thereby improving the effect of electrophoretic wastewater filtration treatment and facilitating subsequent treatment of electrophoretic wastewater, thereby improving the treatment effect of electrophoretic wastewater.

[0004] Once electrophoresis waste liquid is generated, it should not be stored for a long time, otherwise problems such as complex changes in water quality and the proliferation of microorganisms will occur. Therefore, it must be purified in time after it is generated. During the processing of parts, due to the variety of parts types, the amount of electrophoresis waste liquid generated varies significantly. Traditional multi-stage filtration devices use activated carbon adsorption plates with a fixed structure. Although they can perform multi-stage treatment, they cannot automatically adjust the filtration structure according to changes in waste liquid flow. When the flow rate of the waste liquid fluctuates greatly, the fixed filtration structure is easily impacted by the water flow, resulting in damage to the adsorption material or a decrease in filtration efficiency. Especially when processing spare parts from different batches, the difference in waste liquid volume significantly exacerbates this problem. Summary of the Invention

[0034] The following will clearly and completely describe 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figures 1-11 , an electrophoresis processing waste liquid purification system, such as Figure 1-Figure 5As shown, it includes a treatment box 1; a stirring tank 3 and a coarse filtration mechanism 4 are provided in the treatment box 1; the stirring tank 3 and the coarse filtration mechanism 4 are connected by a pipeline; a dosing box 2 is provided on one side of the treatment box 1, and is used to add reagents to the stirring tank 3; it can be understood that the dosing box 2, the stirring tank 3 and the coarse filtration mechanism 4 are all existing technologies, which are not drawn in the figure and will not be described in detail; a microfiltration mechanism 5 is also provided in the treatment box 1, and the coarse filtration mechanism 4 and the microfiltration mechanism 5 are connected by a pipeline; the microfiltration mechanism 5 includes: a buffer tank 51, a partition 52 and an adsorption filtration mechanism 54; wherein the buffer tank 51 is provided in the treatment box 1, and is used to store the electrophoresis waste liquid treated by the coarse filtration mechanism 4; the buffer tank 51 refers to a container structure for receiving and temporarily storing waste liquid, which can be made of corrosion-resistant metal or polymer material; the partition 52 is provided in the buffer tank 51, and is used to separate the buffer tank 51 into a microfiltration purification chamber, which provides an independent space for adsorption filtration to avoid To prevent untreated waste liquid from directly overflowing; the adsorption and filtration mechanism 54 is arranged in the microfiltration purification chamber, and the side wall of the microfiltration purification chamber is provided with an outlet pipe 53. The outlet pipe 53 is arranged at a position lower than the adsorption and filtration mechanism 54, so that the waste liquid is automatically discharged from the outlet pipe 53 under the action of gravity after being filtered by the adsorption and filtration mechanism 54; the adsorption and filtration mechanism 54 includes a plurality of first mounting frames 541 with adsorption plates 542, which are rotatably connected to each other by pins, and a driving mechanism 543 installed on the stirring tank 3; the output end of the driving mechanism 543 is connected to the first mounting frame 541; when the speed of the waste liquid introduced into the microfiltration purification chamber increases, the driving mechanism 543 drives the plurality of adsorption plates 542 on the first mounting frames 541 to expand to increase the aperture through which the waste liquid passes; when the speed of the waste liquid introduced into the microfiltration purification chamber decreases, the driving mechanism 543 drives the plurality of adsorption plates 542 on the first mounting frames 541 to close and fold to reduce the aperture through which the waste liquid passes.

[0036] It should be noted that after the waste liquid enters the buffer tank 51, it is directed to the microfiltration purification chamber through the partition 52. The adsorption plate 542, supported by the first mounting bracket 541, forms an adjustable filtration structure. It is understood that the adsorption plate 542 is an activated carbon adsorption structure, and a bacterial membrane for filtering the waste liquid is cultivated within the pores of the activated carbon adsorption structure. A flow rate sensor can be installed on the delivery pipe of the coarse filtration mechanism 4. It is understood that the flow rate sensor is conventional technology and is not shown in the figure and will not be described in detail. The drive mechanism 543 adjusts the expansion angle of the first mounting bracket 541 based on the signal from the flow rate sensor. When the flow rate increases, the drive mechanism 543 pushes the second mounting bracket 5431 to move, increasing the angle between the first mounting brackets 541, expanding the adsorption plate 542, and moving the second mounting brackets 5431 away from each other. This increases the flow cross-section of the waste liquid flowing through the adsorption plate 542, that is, the instantaneous throughput is increased, thereby allowing the waste liquid to pass through quickly while reducing the impact force of the water flow. When the flow rate decreases, the driving mechanism 543 moves in the opposite direction, and the second mounting frames 5431 move closer to each other, so that the flow cross-section of the waste liquid when flowing through the adsorption plate 542 is reduced, ensuring that the waste liquid has a suitable flow rate to contact the adsorption plate 542 and ensure purification efficiency.

[0037] See also Figure 4 and Figure 6-Figure 7 The driving mechanism 543 includes a second mounting frame 5431 and a driving member 5432; the second mounting frame 5431 is rotatably connected to the first mounting frame 541 through a pin shaft, and the driving member 5432 is installed in the buffer groove 51. The driving member 5432 is used to drive the second mounting frame 5431 to move, so as to drive multiple first mounting frames 541 to expand and move away from each other or fold close to each other.

[0038] It should be noted that the driving member 5432 refers to an actuator that provides linear power, and specifically can be an electric push rod or a hydraulic cylinder, which is used to control the movement direction and stroke of the second mounting bracket 5431 according to the change in the waste liquid flow rate. Expanding and moving away or folding and moving closer refers to the two relative position states formed by multiple first mounting brackets 541 under the action of the driving mechanism 543; by controlling the second mounting brackets 5431 to move closer or further away from each other, when the second mounting brackets 5431 move closer to each other, the waste liquid outlet cross-section decreases, which can increase the speed of the waste liquid passing through the adsorption plate 542 and improve the filtration efficiency; when the second mounting brackets 5431 move away from each other, the waste liquid outlet cross-section increases, which can reduce the speed of the waste liquid passing through the adsorption plate 542 and reduce the impact force on the adsorption plate 542;

[0039] Specifically, when the flow rate of the waste liquid increases, the driving member 5432 pushes the second mounting frame 5431 to move, so that the second mounting frames 5431 move away from each other, increasing the cross-section when the waste liquid passes through, and the multiple first mounting frames 541 are synchronously expanded through the pin drive to adapt to the circulation of the waste liquid and reduce the impact of the high-flow fluid on the adsorption plate 542; when the flow rate of the waste liquid decreases, the driving member 5432 reverses and pulls the second mounting frame 5431 back to reduce the cross-section through which the waste liquid passes, increase the speed at which the waste liquid passes, ensure that the waste liquid has a suitable flow rate to contact the adsorption plate 542, and ensure purification efficiency. Through the linkage design of the driving member 5432 and the second mounting frame 5431, the control of the waste liquid outlet cross-section is realized to control the impact force on the adsorption plate 542, while driving the adaptive adjustment of the expansion degree of the adsorption plate 542, so that the adsorption plate 542 matches the waste liquid flow rate in real time.

[0040] See also Figure 6-Figure 9 The adsorption and filtration mechanism 54 also includes an isolation mechanism 544; the isolation mechanism 544 includes a first isolation cloth 5441, a second isolation cloth 5442, a rotating shaft 5443, a first torsion spring 5444 and a telescopic airbag 5445; the first isolation cloth 5441 is arranged at the rotating connection between adjacent first mounting frames 541; the second isolation cloth 5442 is arranged above the second mounting frame 5431, and one end of the second isolation cloth 5442 is fixed to the inner wall of the microfiltration purification chamber, and the other end of the second isolation cloth 5442 is fixed to the first mounting frame 541 adjacent to the second mounting frame 5431; and the first isolation cloth 5441 and the second isolation cloth 5442 are both elastic structures. When multiple first mounting frames 541 are unfolded or folded, the first isolation cloth 5441 and the second isolation cloth 5442 are both maintained in a taut state.

[0041] It should be noted that when the first mounting frame 541 is driven to expand or fold, the angle of the rotational connection between adjacent first mounting frames 541 changes. At this time, the first isolation cloth 5441 covers the rotation gap through elastic stretching to prevent waste liquid from leaking from the joint. One end of the second isolation cloth 5442 is fixed to the top side wall of the microfiltration purification chamber, and the other end moves synchronously with the displacement of the adjacent first mounting frame 541, compensating for the change in the top space caused by the position change of the second mounting frame 5431 through elastic deformation. When the waste liquid flow rate increases and causes the adsorption plate 542 to expand, the first isolation cloth 5441 is stretched as the first mounting frame 541 rotates, and the second isolation cloth 5442 contracts laterally due to the displacement of the second mounting frame 5431; when the flow rate decreases and causes the adsorption plate 542 to fold, the first isolation cloth 5441 elastically retracts and the second isolation cloth 5442 extends laterally. Therefore, the first isolation cloth 5441 and the second isolation cloth 5442 always maintain surface tension, dynamically filling the geometric gap generated by the movement of the first mounting frame 541 and the second mounting frame 5431, ensuring the sealing of the waste liquid flow path, and forcing the waste liquid to pass through the adsorption plate 542 for filtration.

[0042] See also Figure 7 The rotating shaft 5443 rotates around its axis and is connected to the microfiltration purification chamber. The first torsion spring 5444 is arranged between the rotating shaft 5443 and the microfiltration purification chamber. The rotating shaft 5443 is connected to the second isolation cloth 5442, and when the first torsion spring 5444 loses its restriction, the first torsion spring 5444 is used to drive the rotating shaft 5443 to rotate, so as to drive the second isolation cloth 5442 to unfold or reel.

[0043] It should be noted that when the drive mechanism 543 drives the first mounting frame 541 to expand or fold, the second isolation cloth 5442 stretches or contracts due to the positional changes of the adjacent second mounting frame 5431. At this time, the first torsion spring 5444 automatically retracts and expands the second isolation cloth 5442 through the rotation of the rotating shaft 5443. When the movement of the second mounting frame 5431 increases the tension on the second isolation cloth 5442, the rotating shaft 5443 overcomes the resistance of the first torsion spring 5444 and releases the cloth. When the movement of the second mounting frame 5431 causes the cloth to slacken, the first torsion spring 5444 drives the rotating shaft 5443 to rotate in the opposite direction and retract the excess cloth. During this process, the rotation angle of the rotating shaft 5443 is linked to the displacement of the second mounting frame 5431, ensuring that the second isolation cloth 5442 remains taut, preventing leakage of unfiltered waste liquid due to wrinkles or gaps in the cloth.

[0044] The present application realizes the adaptive expansion or retraction of the second isolation cloth 5442 in the microfiltration purification chamber, ensuring that the second isolation cloth 5442 is always tightly fitted to the inner wall of the chamber and the adjacent structure during the expansion or folding of the adsorption plate 542, effectively preventing unfiltered waste liquid from bypassing the adsorption plate 542 and flowing out directly, thereby maintaining the dynamic sealing performance of the filtration system.

[0045] See also Figure 7-Figure 8 and Figure 10 The isolation mechanism 544 also includes a telescopic airbag 5445; the telescopic airbag 5445 is arranged between the second mounting bracket 5431 and the microfiltration purification chamber. When the multiple first mounting brackets 541 are unfolded or folded, the telescopic airbag 5445 is used to isolate the waste liquid before and after filtration, so that the waste liquid can only be filtered through the adsorption plate 542 and then discharged.

[0046] It should be noted that the telescopic airbag 5445 is positioned between the second mounting frame 5431 and the inner wall of the microfiltration purification chamber. When the second mounting frame 5431 is moved by the drive mechanism 543, the telescopic airbag 5445 elastically expands and contracts with the position of the second mounting frame 5431, consistently sealing the gap between the second mounting frame 5431 and the microfiltration purification chamber. When the first mounting frame 541 is deployed, the second mounting frame 5431 moves, compressing the telescopic airbag 5445. When the first mounting frame 541 is folded, the second mounting frame 5431 moves, extending the telescopic airbag 5445. This dynamic deformation process allows the telescopic airbag 5445 to continuously form a physical isolation barrier, preventing unfiltered waste liquid from leaking from the area around the second mounting frame 5431 into the filtered area.

[0047] This ensures that the waste liquid flow path within the microfiltration purification chamber is strictly controlled, ensuring that unfiltered waste liquid cannot bypass adsorption plate 542 under varying flow rate conditions, thus resolving leakage and mixing issues during dynamic adjustment. The elastic sealing structure also adapts to the movement of the second mounting bracket 5431 without additional drive, ensuring the stability and reliability of the filtration operation.

[0048] See also Figure 1 、 Figure 4 、 Figure 6 and Figure 11 A circulation filtering mechanism 545 is provided on the processing box 1; the circulation filtering mechanism 545 includes an inlet pipe 5451, a connecting pipe 5452, a filter 5453 and a one-way valve 5454; one end of the inlet pipe 5451 is connected to the telescopic airbag 5445, and the other end of the inlet pipe 5451 extends into the bottom of the microfiltration purification chamber; the one-way valve 5454 is arranged in the inlet pipe 5451, and is used to allow the waste liquid at the bottom of the microfiltration purification chamber to be introduced into the telescopic airbag 5445 through the inlet pipe 5451; the filter 5453 is installed in the processing box 1, and the input end of the filter 5453 is connected to the telescopic airbag 5445 through the connecting pipe 5452, and the output end of the filter 5453 is connected to the microfiltration purification chamber through the output pipe.

[0049] It should be noted that when the telescopic airbag 5445 is stretched and extended, negative pressure is generated inside, so that the waste liquid deposited at the bottom of the microfiltration purification chamber is sucked into the telescopic airbag 5445 through the inlet pipe 5451. At this time, the one-way valve 5454 is forced to open, allowing the waste liquid to flow in; when the telescopic airbag 5445 is compressed and shortened, positive pressure is generated inside, so that the waste liquid in the telescopic airbag 5445 is introduced into the filter 5453 for filtration and purification, and then re-introduced into the microfiltration purification chamber.

[0050] During this process, filter 5453 performs molecular-level filtration on the remaining waste liquid, and the output tube re-introduces the treated liquid into the purification process, forming a closed loop. The elastic deformation properties of the telescopic airbag 5445 not only serve as a temporary storage container to buffer flow fluctuations, but also generate a pressure differential through volume changes to drive the filtration process.

[0051] This solution dynamically adjusts the storage volume through the telescopic airbag 5445, combined with the one-way flow design, to simultaneously complete the temporary storage and transfer of waste liquid during the filtration stage, avoiding the formation of a dead water area at the bottom of the purification chamber.

[0052] Example 2: This example differs from Example 1 in that: Figures 8-10 The adsorption and filtration mechanism 54 also includes a control mechanism 546; the control mechanism 546 includes a third isolation cloth 5461, a winding wheel 5462, a connecting rope 5463; a reel 5464 and a linkage mechanism; the winding wheel 5462 is coaxially connected to the rotation connection position between the second mounting frame 5431 and the first mounting frame 541, the third isolation cloth 5461 is wound around the winding wheel 5462, the winding wheel 5462 is coaxially connected to the rotation connection position between the adjacent first mounting frames 541, the connecting rope 5463 is wound around the winding wheel 5462, and one end of the connecting rope 5463 is connected to the third isolation cloth 5461; the winding wheel 5462 is coaxially connected to the first mounting frame 541. A second torsion spring is provided at the rotation connection position between the mounting brackets 541, and the second torsion spring is used to control the third isolation cloth 5461 to maintain a taut state; by controlling the third isolation cloth 5461 to be wound or unwound on the winding wheel 5462, the third isolation cloth 5461 is driven to block the adsorption plate 542 to different degrees; the linkage mechanism is provided on the second mounting bracket 5431, and is used to control the rotation of the winding wheel 5462; the linkage mechanism includes a gear 5465 coaxially fixed on the winding wheel 5462; a slide groove parallel to the moving direction of the second mounting bracket 5431 is provided on the inner wall of the microfiltration purification chamber, and a tooth groove adapted to the gear 5465 is provided in the slide groove.

[0053] It should be noted that when the waste liquid flow rate increases, the drive mechanism 543 pushes the second mounting bracket 5431 to move, and the gear 5465 in the linkage mechanism engages with the teeth in the chute, driving the winding wheel 5462 to rotate. The connecting rope 5463 is released as the winding wheel 5462 rotates, and the third isolation cloth 5461 unfolds under the tension of the second torsion spring, reducing the area blocked by the adsorption plate 542. At this point, the adsorption plate 542 is further expanded, allowing more waste liquid to pass while maintaining the effective filtration area. When the waste liquid flow rate decreases, the second mounting bracket 5431 moves in the opposite direction, and the gear 5465 drives the winding wheel 5462 to rotate in the opposite direction. The connecting rope 5463 is wound and tightened, and the third isolation cloth 5461 gradually covers part of the surface of the adsorption plate 542, reducing the available filtration area of ​​the adsorption plate 542. The second torsion spring continuously provides reverse torque, ensuring that the third isolation cloth 5461 remains taut during dynamic adjustment, preventing wrinkles in the cloth from creating leakage channels for unfiltered waste liquid.

[0054] A linkage mechanism converts the displacement of the second mounting bracket 5431 into the rotation of the winding wheel 5462, creating a linkage between the coverage area of ​​the third isolation cloth 5461 and the extent of expansion of the adsorption plate 542. As the waste liquid flow rate changes, the third isolation cloth 5461 automatically adjusts its coverage, maintaining the tightness of the filtration area while ensuring a dynamic match between the effective filtration area of ​​the adsorption plate 542 and the flow rate. This overcomes the technical drawback of fixed filtration structures, which are susceptible to flow shock. Furthermore, the area of ​​the adsorption plate 542 covered by the third isolation cloth 5461 is protected from the impact of the waste liquid, providing ample space for bacterial growth within the adsorption plate 542.

[0055] See also Figure 9-10 A connecting rod 5466 is provided between the third isolation cloth 5461 and the connecting rope 5463 , and the connecting rod 5466 is adsorbed on the first mounting frame 541 .

[0056] It should be noted that when the third isolation cloth 5461 is wound or unwound by the winding wheel 5462, the rigid structure of the connecting rod 5466 can limit the relative displacement between the third isolation cloth 5461 and the connecting rope 5463, avoiding local wrinkles or misalignment caused by the flexible connection. Under the action of adsorption, the fixed relationship between the connecting rod 5466 and the first mounting frame 541 can offset the impact of water flow on the position of the third isolation cloth 5461, while ensuring that the coverage range of the adsorption plate 542 by the third isolation cloth 5461 when unfolded is synchronized with the action of the drive mechanism 543. For example, when the first mounting frame 541 is unfolded or folded due to changes in the waste liquid flow rate, the adsorbed and fixed connecting rod 5466 moves synchronously with it, driving the third isolation cloth 5461 to cover or expose the surface of the adsorption plate 542 along a preset trajectory.

[0057] By using the rigid connecting rod 5466 and the adsorption fixing method, the position stability of the key connection points is enhanced while maintaining the flexibility of the third isolation cloth 5461, thereby avoiding filtration failure caused by loosening.

[0058] See also Figure 1-2 , a water pump is installed on the processing box 1; it can be understood that the water pump is a prior art, which is not shown in the figure and will not be described in detail. The water pump is installed between the buffer tank 51 and the microfiltration purification chamber, and is used to introduce the waste liquid in the buffer tank 51 into the microfiltration purification chamber for filtration and treatment through the adsorption filtration mechanism 54; a water pressure gauge 6 is provided on the buffer tank 51. When the water pressure detected by the water pressure gauge 6 is too high, the water pump can be controlled to start to speed up the efficiency of waste liquid extraction.

[0059] It should be noted that once the waste liquid enters the buffer tank 51, the water pump actively adjusts the delivery pressure based on the water pressure changes in the water pressure gauge 6, pumping the waste liquid in the buffer tank 51 into the microfiltration purification chamber at a controllable rate. As the amount of waste liquid increases, the water pump increases the delivery pressure, causing the adsorption plates 542 in the adsorption filter mechanism 54 to expand and enlarge the filter aperture, while maintaining a sufficient pressure differential to ensure filtration efficiency.

[0060] The forced delivery system established by the water pump in this application can accurately control the flow rate of the waste liquid entering the microfiltration purification chamber, so that the expansion or folding action of the adsorption plate 542 is synchronized with the waste liquid flow in real time, eliminating the impact of sudden flow rate changes on the filtration structure in the passive filtration mode.

[0061] Through the above technical solution, the present application realizes the dynamic adaptation of the waste liquid treatment rate and the filtration structure, ensures the stability of the filtration pressure difference under different flow conditions, effectively prevents the decrease in filtration efficiency or impurity leakage caused by fluctuations in the waste liquid flow rate, and significantly improves the treatment system's adaptability to changes in waste liquid volume during electrophoresis processing.
