Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device for electrolytic copper foil processing. Background Technology

[0002] Wastewater is a significant source of pollution during the electrolytic copper foil processing. Electrolytic copper foil production typically involves multiple stages, including copper electrolysis, surface treatment, pickling, degreasing, and cleaning. These processes generate wastewater containing heavy metals, acids, alkalis, greases, and other harmful chemicals. Wastewater treatment is essential to ensure environmental protection and compliance with relevant emission standards.

[0003] Patent publication number CN218372006U relates to a wastewater treatment device for electrolytic copper foil production, comprising a main body of the treatment device and a second filtration structure. The main body of the treatment device has a first bearing inside, and a rotating rod is mounted on the top of the first bearing. A first filtration structure is mounted on the outer wall of the rotating rod, and mounting plates are mounted on both sides of the top of the first filtration structure. A top plate is mounted above the mounting plates, and mounting rods are mounted at the four bottom corners of the top plate. Mounting blocks are connected to the outer sides of the mounting rods. A first outlet is pre-installed at the bottom of the main body of the treatment device, and a connecting rod is mounted on the outer side of the first outlet. The second filtration structure is located at the bottom of the connecting rod. This patent can effectively and fully adsorb impurities in the wastewater, thereby improving the wastewater treatment effect of the device and removing odors from the wastewater from electrolytic copper foil production, resulting in less odor in the wastewater.

[0004] In the aforementioned patent, the second filtration structure can remove odors from the wastewater from electrolytic copper foil production, resulting in less odor in the wastewater. However, the liquid from the first filtration layer will directly enter the second filtration layer, which may lead to insufficient filtration. Therefore, an electrolytic copper foil processing wastewater treatment device with adjustable flow is designed to fully filter impurities in the wastewater. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a wastewater treatment device for electrolytic copper foil processing, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: an electrolytic copper foil processing wastewater treatment device, comprising a main body, a bucket lid placed on the top of the main body, a liquid outlet opened at the bottom of the main body, a layered plate fixedly installed inside the main body, and further comprising an adjustment device, a longitudinal stirring device, and a vibration cleaning device.

[0007] The regulating device includes a motor, which is fixedly installed below the layered plate. A rotating rod is fixedly installed at the output end of the motor. A frame is fixedly installed on the circumference of the rotating rod. An activated carbon adsorption plate is placed inside the frame. A fixing plate is fixedly installed on the circumference of the rotating rod. A slider is slidably installed between the fixing plates. A toothed block is fixedly installed on the side of the slider away from the rotating rod. A ring is rotatably installed above the layered plate. A toothed block is fixedly installed on the inner circumference of the ring. A nanofiltration membrane is provided at the bottom of the main body. When the ring rotates, if its hole coincides with the hole on the layered plate, wastewater enters the second filtration layer through the hole. After being filtered by the nanofiltration membrane in the second filtration layer, it is discharged from the outlet. The nanofiltration membrane can remove the odor in the wastewater from the electrolytic copper foil production, avoiding the situation where the wastewater enters the second filtration layer before being fully filtered in the first filtration layer. This greatly improves the filtration capacity of the device and can fully filter impurities in the wastewater.

[0008] According to the above technical solution, a spring is provided between the slider and the rotating rod, a hole is opened in the middle of the first ring, and a hole that is misaligned with the first ring is opened in the middle of the layered plate. When the first toothed block rotates counterclockwise, its inclined surface contacts the inclined surface of the second toothed block, and relative movement occurs. Under the action of the spring, the slider will slide back and forth between the fixed plates. The misalignment design of the hole is to prevent water from entering the second filter layer when the first ring is not rotating.

[0009] According to the above technical solution, one side of the toothed block is set as an inclined surface and the other side is set as a straight surface, and one side of the toothed block is set as an inclined surface and the other side is set as a straight surface. When the inclined surfaces are in contact with each other, the movement of the slider will not cause the first ring to rotate, while when the straight surfaces are in contact with each other, the movement of the slider will cause the first ring to rotate.

[0010] According to the above technical solution, the longitudinal stirring device includes a fixed rod 1, which is fixedly installed at the bottom of the frame. A ring 2 is fixedly installed at the end of the fixed rod 1 away from the frame. A toothed block 3 is fixedly installed above the ring 2. A round rod is fixedly installed on the inner wall of the main body. A cylinder is rotatably installed on the circumference of the round rod. A stirring plate is fixedly installed on the circumference of the cylinder. A disc is fixedly installed at the end of the cylinder away from the main body. A toothed block 4 is fixedly installed on the circumference of the disc. The rotation of the cylinder drives the stirring plate to rotate. The rotation of the stirring plate treats the sediment above the stratification plate, preventing solid impurities in the wastewater from accumulating at the bottom of the first filter layer, thus improving the wastewater treatment effect of the device and further improving the wastewater treatment efficiency of the device.

[0011] According to the above technical solution, a second fixing rod is fixedly installed on the side of the frame close to the main body, and a cleaning rod is fixedly installed on the end of the second fixing rod away from the frame. The rotation of the second fixing rod drives the cleaning rod to rotate, and the rotation of the cleaning rod cleans the inner wall of the main body, preventing impurities in the wastewater from adhering to the inner wall of the main body, improving the wastewater treatment effect of the device, and further improving the wastewater treatment efficiency of the device.

[0012] According to the above technical solution, the second ring is rotatably installed above the layered plate, the third toothed block meshes with the fourth toothed block, and the rotation of the third toothed block drives the fourth toothed block that meshes with it to rotate.

[0013] According to the above technical solution, the vibration cleaning device includes a cover plate placed above a frame. An activated carbon adsorption plate is fixedly installed below the cover plate, and a dust collection box is fixedly installed at the bottom of the activated carbon adsorption plate. A baffle is fixedly installed inside the dust collection box, and rollers are rotatably installed between the baffles. A protrusion is fixedly installed inside the frame. During the movement of the dust collection box, the dust adhering to the inside of the frame is cleaned. The movement of the dust collection box drives the baffle to move, and the movement of the baffle drives the rollers to roll inside the frame. During the rolling of the rollers, they contact and misalign with the protrusions fixed inside the frame to generate a vibration effect, effectively cleaning the dust adhering to the frame and preventing dust from adhering to the inside of the frame and being difficult to handle.

[0014] According to the above technical solution, the top of the dust collection box is set as an inclined surface, and a locking block is set below the cover plate to fix the cover plate in place, so as to prevent the activated carbon adsorption plate from being thrown out of the frame and damaged when the first filter layer is working.

[0015] This invention provides a wastewater treatment device for electrolytic copper foil processing. It has the following beneficial effects: (1) The wastewater treatment device for electrolytic copper foil processing is made by rotating the toothed block one clockwise so that its straight surface contacts the straight surface of the toothed block two, which in turn drives the toothed block two to rotate clockwise. The rotation of the toothed block two drives the ring one to rotate. When the ring one rotates, when the hole on it coincides with the hole on the layer plate, the wastewater enters the second filter layer through the hole. After being filtered by the nano-filter membrane in the second filter layer, it is discharged from the outlet. The nano-filter membrane can remove the odor in the wastewater from electrolytic copper foil production, avoiding the situation where the wastewater enters the second filter layer before being fully filtered in the first filter layer. This greatly improves the filtration capacity of the device and can fully filter the impurities in the wastewater.

[0016] (2) The wastewater treatment device for electrolytic copper foil processing drives the stirring plate to rotate through the rotation of the cylinder. The rotation of the stirring plate treats the sediment above the layered plate, preventing solid impurities in the wastewater from accumulating at the bottom of the first filter layer, thus improving the wastewater treatment effect of the device and further improving the wastewater treatment efficiency of the device. The rotation of the fixed rod drives the cleaning rod to rotate, thus cleaning the inner wall of the main body, preventing impurities in the wastewater from adhering to the inner wall of the main body, thus improving the wastewater treatment effect of the device and further improving the wastewater treatment efficiency of the device.

[0017] (3) The wastewater treatment device for electrolytic copper foil processing cleans the dust attached to the inside of the frame by the movement of the dust collection box. The movement of the dust collection box drives the baffle to move, and the movement of the baffle drives the roller to roll inside the frame. During the rolling process, the roller contacts the protrusion fixed inside the frame and generates a vibration effect, which effectively cleans the dust attached to the frame and avoids the dust from being attached to the frame and difficult to deal with. The cover plate is fixed with a card block to prevent the activated carbon adsorption plate from being thrown out of the frame and damaging the activated carbon adsorption plate when the first filter layer is working.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-10 One embodiment of the present invention is: an electrolytic copper foil processing wastewater treatment device, including a main body 1, a bucket cover 2 placed on the top of the main body 1, a liquid outlet 3 opened at the bottom of the main body 1, a layered plate 5 fixedly installed inside the main body 1, and also including an adjustment device, a longitudinal stirring device and a vibration cleaning device.

[0022] The adjusting device includes a motor 6, which is fixedly installed below the layered plate 5. A rotating rod 601 is fixedly installed at the output end of the motor 6. A frame 4 is fixedly installed on the circumference of the rotating rod 601. An activated carbon adsorption plate 701 is placed inside the frame 4. A fixing plate 602 is fixedly installed on the circumference of the rotating rod 601. A slider 603 is slidably installed between the fixing plates 602. A toothed block 604 is fixedly installed on the side of the slider 603 away from the rotating rod 601. A ring 606 is rotatably installed above the layered plate 5. A toothed block 605 is fixedly installed on the inner circumferential surface of the ring 606. A nano-filter membrane 608 is set at the bottom of the main body 1. When the ring 606 rotates, when the hole on it coincides with the hole on the layered plate 5, the wastewater enters the second filter layer through the hole. After being filtered by the nano-filter membrane 608 in the second filter layer, it is discharged from the outlet 3. The nano-filter membrane 608 can remove the odor in the wastewater from the electrolytic copper foil production, avoiding the situation where the wastewater enters the second filter layer before being fully filtered in the first filter layer.

[0023] A spring 607 is provided between the slider 603 and the rotating rod 601. A hole is opened in the middle of the first ring 606. A hole that is misaligned with the first ring 606 is opened in the middle of the layered plate 5. The first toothed block 604 rotates counterclockwise and its inclined surface contacts the inclined surface of the second toothed block 605, resulting in relative movement. Under the action of the spring 607, the slider 603 will slide back and forth between the fixed plates 602. The misalignment design of the hole is to prevent water from entering the second filter layer when the first ring 606 is not rotating.

[0024] One side of the toothed block 604 is set as an inclined surface and the other side is set as a straight surface. One side of the toothed block 605 is set as an inclined surface and the other side is set as a straight surface. When the inclined surfaces are in contact with each other, the movement of the slider 603 will not cause the ring 606 to rotate. When the straight surfaces are in contact with each other, the movement of the slider 603 will cause the ring 606 to rotate.

[0025] In this embodiment, during operation: The lid 2 is removed, wastewater is poured into the main body 1, the lid 2 is closed, the motor 6 is started, and the rotating rod 601 is controlled to rotate counterclockwise. The first filter layer begins to work. The rotation of the rotating rod 601 drives the fixed plate 602 to rotate counterclockwise, which in turn drives the slider 603 to rotate counterclockwise. The slider 603 then drives the toothed block 604 to rotate counterclockwise. The inclined surface of the toothed block 604 contacts the inclined surface of the toothed block 605, resulting in relative motion. Under the action of the spring 607, the slider 603 slides back and forth between the fixed plates 602. The rotation of the rotating rod 601 drives the frame 4 to rotate, which in turn drives the activated carbon adsorption plate 701 to rotate, adsorbing some heavy metal ions from the wastewater. After the first filter layer has worked sufficiently, the motor 6 is started to control the rotating rod 601 to rotate clockwise. The rotation of the first filter causes the fixed plate 602 to rotate clockwise, which in turn causes the slider 603 to rotate clockwise. The slider 603 then causes the toothed block 604 to rotate clockwise. As the toothed block 604 rotates clockwise, its straight surface comes into contact with the straight surface of the second toothed block 605, causing the second toothed block 605 to rotate clockwise. The rotation of the second toothed block 605 then causes the ring 606 to rotate. When the ring 606 rotates, its hole coincides with the hole on the layered plate 5, and the wastewater enters the second filter layer through the hole. After being filtered by the nanofiltration membrane 608 in the second filter layer, the wastewater is discharged from the outlet 3. The nanofiltration membrane 608 can remove the odor from the wastewater produced by electrolytic copper foil production, preventing the wastewater from entering the second filter layer before it has been fully filtered in the first filter layer. This greatly improves the filtration capacity of the device and can fully filter the impurities in the wastewater.

The rotation of the stirring plate 406 treats the sediment above the layered plate 5, preventing solid impurities in the wastewater from accumulating at the bottom of the first filter layer, thereby improving the wastewater treatment effect of the device and further improving the wastewater treatment efficiency of the device.

[0027] A fixing rod 409 is fixedly installed on the side of the frame 4 close to the main body 1. A cleaning rod 410 is fixedly installed on the end of the fixing rod 409 away from the frame 4.

[0029] In this embodiment, during operation: when wastewater is filtered in the first filter layer, the rotation of the circular rod 404 drives the frame 4 to rotate, the rotation of the frame 4 drives the fixed rod 401 to rotate, the rotation of the fixed rod 401 drives the ring 402 to rotate, the rotation of the ring 402 drives the toothed block 403 to rotate, the rotation of the toothed block 403 drives the meshing toothed block 408 to rotate, the rotation of the toothed block 408 drives the disc 407 to rotate, and the rotation of the disc 407 drives the cylinder 405 to rotate on the circumference of the circular rod 404, and the rotation of the cylinder 405 drives the stirring plate 406 to rotate. The rotating agitator 406 treats the sediment above the layered plate 5, preventing solid impurities in the wastewater from accumulating at the bottom of the first filter layer, thus improving the wastewater treatment effect and efficiency of the device. The rotating frame 4 drives the second fixing rod 409 to rotate, which in turn drives the cleaning rod 410 to rotate. The cleaning rod 410 cleans the inner wall of the main body 1, preventing impurities in the wastewater from adhering to the inner wall of the main body 1, thus improving the wastewater treatment effect and efficiency of the device.

[0032] In this embodiment, when the activated carbon adsorption plate 701 in the first filter layer needs to be replaced, the lid 2 is removed, and the cover plate 7 is taken out. The movement of the cover plate 7 causes the activated carbon adsorption plate 701 to move, which in turn causes the dust collection box 702 to move. During the movement of the dust collection box 702, the dust adhering to the inside of the frame 4 is cleaned. The movement of the dust collection box 702 causes the baffle 704 to move, which in turn causes the roller 705 to roll inside the frame 4.
