In the copper strip processing, the cleaning process is the key step to ensure the surface quality of the copper strip. It mainly involves pretreatment, degreasing, water washing, pickling (as needed), surface treatment (optional), drying and post-treatment inspection to remove surface oil, oxides, dust and other impurities.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a copper strip cleaning line cleaning fluid recycling device, including a separation tank 1, and a circulation mechanism 2 in the middle of the separation tank 1 for recycling the copper strip cleaning line cleaning fluid. The circulation mechanism 2 includes:

[0029] The pretreatment component 21 includes a filter box 211 fixedly installed on one side of the top of the separation box 1. Two inclined filter plates 212 are detachably installed in the middle of the filter box 211, and the two filter plates 212 are inclined to each other to increase the contact path and contact area between the cleaning liquid and the filter plates 212, thereby improving the impurity interception efficiency and filtration effect. A collection tank 213 can be detachably installed at one end of each of the two filter plates 212.

[0030] The oil-water separation assembly 22 includes an isolation baffle 223 fixedly installed in the middle of the separation tank 1. The isolation baffle 223 has three equally spaced baffles, which are staggered. Two symmetrically distributed diversion baffles 221 are fixedly installed on the upper side of the separation tank 1, located on the upper sides of the left isolation baffle 223. A limiting block 2211 is fixedly installed at the bottom of one of the diversion baffles 221.

An aeration fan 222 is installed at the lower part of the separation tank 1. This aeration fan 222 can be... Model: Best HC-50S. This blower is equipped with a variable frequency speed controller, which can dynamically adjust the aeration volume according to the oil content of the cleaning fluid. A separation frame 225 is fixedly installed on the upper side of the separation box 1. Two sets of oil scraping belts 226 are installed on the upper part of the separation frame 225. Both sets of oil scraping belts 226 are driven by traditional servo motors, which will not be described in detail here. Two symmetrically distributed scrapers 227 are fixedly installed in the middle of the separation frame 225. One side of each scraper 227 is in contact with the outer surface of one side of the oil scraping belt 226. A recovery box 228 is slidably installed through the middle of the separation frame 225.

[0032] The neutralization component 23 includes a mixing box 231 fixedly installed on one side of the separation box 1. One side of the three-way pipe 224 is connected to the mixing box 231. A hopper 235 is fixedly installed at the top center of the mixing box 231. A rotating shaft 236 is rotatably installed at the center of the hopper 235. A drive component is provided at the top of the rotating shaft 236. A spiral conveyor blade 238 is fixedly installed at the bottom of the rotating shaft 236.

[0033] The stirring assembly includes stirring rods 232 rotatably mounted in the middle of the mixing tank 231, and two stirring rods 232 are provided for mutual cooperation. Gears 234 are fixedly mounted on one side of each stirring rod 232, and the two gears 234 are meshed with each other. A drive motor 233 is fixedly mounted on one side of the mixing tank 231. The drive motor 233 can be a three-phase permanent magnet synchronous motor, model WMPMA250M-10-10-37kW. One end of one of the stirring rods 232 is fixedly mounted on the drive end of the drive motor 233. Under the drive of the drive motor 233, the two stirring rods 232 rotate synchronously and relative to each other through the meshing transmission of the two gears 234, so as to fully stir and mix the cleaning solution and the added drugs inside, and quickly adjust it to the required pH value.

[0034] A conveying pipe 214 is fixedly installed at the bottom of the filter box 211. The conveying pipe 214 slides through the middle of the diversion baffle 221 and is used to discharge the filtered liquid in the filter box 211 into the separation box 1.

[0036] Multiple rotating plates 237 arranged in a ring array are fixedly installed on the upper part of the rotating shaft 236. The outer sides of the multiple rotating plates 237 are in contact with the inner wall of the hopper 235. The multiple rotating plates 237 rotate under the rotation of the rotating shaft 236, and the solvent or drug adhering to the inner wall of the hopper 235 is scraped off.

[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0038] During operation, the cleaning fluid is first placed inside the filter box 211 and filtered by the filter plate 212. The two filter plates 212 are set at an angle to increase the contact path and contact area between the cleaning fluid and the filter plate 212, thereby improving the impurity interception efficiency and filtration effect. The pore sizes of the impurity interception holes on the two filter plates 212 are different, and the filtration holes of the upper filter plate 212 are larger than those of the lower layer, so as to achieve the effect of layered filtration. The impurities are flushed and flow into the collection tank 213 for collection. The cleaning fluid flows into the separation box 1 through the filter holes and the delivery pipe 214. The cleaning fluid flows into the lower part of the left isolation baffle 223 through the three staggered isolation baffles 223, then flows through the upper part of the middle isolation baffle 223, and finally flows out through the lower part of the right isolation baffle 223.

[0039] Meanwhile, as the cleaning fluid passes under the left isolation baffle 223, the aeration fan 222 at its lower part blows air into the oil-containing copper strip cleaning fluid, generating a large number of tiny bubbles. These bubbles adhere to the surface of the oil droplets, further reducing the overall density of the oil droplets, which are originally less dense than water, thus accelerating the oil droplets to float to the surface. At the same time, when the oil level is higher than the height of the middle isolation baffle 223, it is moved closer to the left isolation baffle 223 by the combined limitation of its guide baffle 221 and the limiting block 2211. The cleaning fluid flows out through the gap between the limiting block 2211 and the middle isolation baffle 223, reaching the other side of the middle isolation baffle 223. Due to the vertical connection of the three-way pipe 224, the water level remains at the same level under the same atmospheric pressure. The three-way pipe 224 automatically overflows and discharges the bottom clean water, thereby achieving the oil-water separation effect.

[0040] The oil sludge suspended on both sides of the two diversion baffles 221 is rotated by a conventional servo motor driven by the oil scraper belt 226. The lower part of the oil scraper belt 226 comes into contact with the surface oil sludge of the cleaning fluid, adsorbing the oil sludge onto the oil scraper belt 226. As it rotates, the scraper 227 comes into contact with the surface of the oil scraper belt 226, scraping off the adsorbed oil sludge, allowing the oil sludge to flow along the scraper 227 into the interior of the recovery box 228.

[0041] The cleaning solution flows into the mixing tank 231 after being discharged through the three-way pipe 224. By detecting the pH value and metal ion concentration of the cleaning solution, acidic or alkaline ion solutions are automatically added to the cleaning solution. Driven by the servo motor 239, the rotating shaft 236 rotates, which in turn drives the spiral conveyor blade 238 to rotate, thereby quantitatively delivering the acidic or alkaline ion solution into the mixing tank 231. Driven by the drive motor 233, one of the stirring rods 232 rotates, which in turn drives one of the gears 234 to rotate. Through the meshing transmission of the two gears 234, the two stirring rods 232 rotate synchronously and in opposite directions, mixing the cleaning solution and the acidic or alkaline ion solution inside. After mixing, it is discharged through the drain pipe at the bottom and transported to the cleaning tank for recycling.
