Description

Technical Field

[0001] The utility model belongs to the technical field of strip production, and more specifically relates to a strip production cleaning line structure. Background Art

[0002] During the copper strip cleaning process, without affecting the surface cleaning quality of the copper strip, on the one hand, it is necessary to ensure that there is sufficient water in each brush box for continuous spraying, and at the same time, to avoid overflowing into the external wastewater pool as little as possible, so as to achieve a state of water use in the entire system to a certain extent as much as possible, with less overflow, water conservation and environmental protection. Currently, during the cleaning process, after the copper strip passes through the grinding box and the cleaning box, a lot of fine brush hairs and copper powder and other impurities will be cleaned out. These impurities are filtered through the non-woven fabric of the vacuum filter, which can remove most of the brush hairs. However, there are still finer impurities that cannot be cleaned. Directly draining this water will result in a waste of water resources. Directly using water with impurities for strip grinding and cleaning will affect the quality of the strip.

[0003] The prior art includes a technology entitled "An Ultrafiltration Membrane Air Blowing Backwashing Device for Reusing Glass Grinding Wastewater" and publication number "CN205796979U." This technology discloses an ultrafiltration membrane air blowing backwashing device for reusing glass grinding wastewater, comprising a raw water tank, a filter, an ultrafiltration assembly having an ultrafiltration membrane therein, and a produced water tank connected by pipelines. The ultrafiltration assembly is provided with at least one ultrafiltration assembly, and further comprises a compressed air charging device capable of charging compressed air into the ultrafiltration membrane assembly. The compressed air charging device is connected to the bottom end of the ultrafiltration assembly via a compressed air pipeline. The utility model provides a compressed air charging device to charge compressed air into the ultrafiltration assembly, purge the surface of the ultrafiltration membrane with compressed air, and then backwash the ultrafiltration membrane to quickly remove impurities on the ultrafiltration membrane, thereby extending the chemical cleaning cycle of the ultrafiltration membrane, improving the purification and filtration efficiency, and extending the service life of the ultrafiltration membrane. This increases the water production of wastewater reuse, reduces wastewater discharge, conserves water resources, and saves production costs. The device has a simple structure and is easy to implement, which is conducive to the popularization and application of the device. This technology does not involve the technical problems and technical solutions of this application. Utility Model Content

The grinding tank 8 is connected to the cold water buffer tank 5 via a fifth pipeline 11. The cold water buffer tank 5 is connected to the water inlet of a second backwash filter 12 via a sixth pipeline 16. The water outlet of the second backwash filter 12 is connected to the second clear water tank 9. This structure addresses the shortcomings of the prior art and provides an improved technical solution. During the structural configuration, water treatment components are provided corresponding to the cleaning tank 3 and the grinding tank 8. The cleaning tank 3 and grinding tank 8 are used to purify the water after strip processing, respectively, achieving water recycling and conserving water resources. Furthermore, the treated water prevents environmental pollution caused by the discharge of impurities, thus promoting environmental protection. When cleaning the copper strip, the cleaning tank draws water from the first clear water tank via a first pipeline. After rinsing the copper strip in the cleaning tank, the rinsed water is initially filtered by a first vacuum filter in a second pipeline before returning to the cold water buffer tank 5. The cold water buffer tank is then pumped via a third pipeline to the first backflush filter, where it is filtered through the filter element of the first backflush filter, further filtering the water in the cold water buffer tank and producing even cleaner water. As the liquid level in the first backflush filter rises, the filtered water overflows into the first clear water tank (the first clean water tank) for storage. It is then supplied to the cleaning tank for spraying, and the sprayed water then flows back to the cold water buffer tank, completing a complete water cycle. When the grinding box is cleaning the copper strip, water from the second clear water tank is sent to the grinding box via the fourth pipeline. After the grinding box rinses the copper strip, the used water is initially filtered through the second vacuum filter on the fifth pipeline and returned to the cold water buffer tank 5. The water from the cold water buffer tank is then pumped to the second backflush filter via the sixth pipeline. It is filtered by the filter element of the second backflush filter, achieving further filtration of the water in the cold water buffer tank and obtaining even cleaner water. As the liquid level in the first backflush filter rises, the filtered water from the second backflush filter overflows into the second clear water tank (the first clean water tank) for storage. It is then supplied to the grinding box for spraying. The sprayed water then flows back to the cold water buffer tank, thus completing a water cycle. The structure of the utility model forms a water circulation equipment pipeline through components such as a backwash filter, a vacuum filter, a water pump (boosting pump, multi-stage centrifugal pump), a spray box, a clean water tank (clean water tank), and a cold water buffer tank. Through the effective control of each step, the water with impurities after the strip cleaning can be purified, thereby realizing the recycling of water, reducing the amount of tap water replenishment, and lowering the cost of water use.The strip production cleaning line structure described in the utility model is simple in structure and can conveniently and reliably purify the water in the cleaning tank and grinding tank, meeting the water quality requirements for recycling, reducing the process and cost of water treatment in the production line, improving water treatment efficiency, saving water resources and achieving environmental protection.
