Description

Technical Field

[0001] The utility model mainly relates to the technical field of foil washing water treatment equipment for a raw foil machine, in particular to a foil washing water recovery device for a raw foil machine unit. Background Art

[0002] In the process of electrolytic copper foil production, a raw foil machine is needed. The processing flow of the raw foil machine mainly includes the raw foil leaving the electrolyte, pickling, liquid squeezing roller, water washing, water squeezing roller, drying and rolling out the raw foil. In the process of copper foil production, electrolytic copper is first made into copper sulfate solution, and then electrolyzed in the raw foil machine to produce raw foil. The raw foil is then subjected to surface electroplating treatment to obtain the finished product. Each process requires a water washing process, and the wastewater generated in these processes is foil washing water.

[0003] These foil washing waters contain a small amount of un-electrolyzed copper ions and sulfuric acid generated by electrolysis, and cannot be discharged directly. Generally, they need to be collected in a transfer tank and then treated together. However, in the entire electrolytic copper foil production process, a large amount of foil washing water will be generated. If it is only used once, it will cause a lot of waste and increase production costs. Therefore, many manufacturers now reuse the foil washing water. However, when the foil washing water in the transfer tank is reused, as the foil washing water in the transfer tank gradually decreases, the water pressure at the outlet is also decreasing, which is not conducive to controlling the flow rate. In addition, if the water pressure is insufficient, the flushing area will be unclean. If it is lower than the critical point, the water pressure in the pipeline will not be enough to rise and flow into the area that needs to be cleaned, and flushing cannot be carried out, affecting work efficiency.

DETAILED DESCRIPTION

Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0021] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field of the present invention. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] Please refer to the attached Figure 1-3 A foil washing water recovery device of a foil raw machine unit includes a foil washing water boosting mechanism 1 and a filter 2, and the foil washing water boosting mechanism 1 and the filter 2 are connected by a flange, the foil washing water boosting mechanism 1 includes a recovery transfer tank 11, and four docking ports 111 are arranged on the upper side of the recovery transfer tank 11, and three water pressure sensors 12 and a water injection pipe 13 are respectively arranged in the four docking ports 111, and a drainage pipe 16 is arranged on one side of the bottom of the recovery transfer tank 11, and the drainage pipe 16 is connected to a boosting pump 17 through a flange, and the control module of the boosting pump 17 and the water pressure sensor 12 are electrically connected.

[0024] The above structure realizes that after the water pressure in the recovery transfer tank 11 drops to a critical point, the foil washing water can be automatically pressurized through the foil washing water boosting mechanism 1, so as to meet the flow and rise in the subsequent pipeline, reasonably control the flow rate, and effectively avoid the problem of unclean flushing caused by insufficient water pressure, thereby ensuring the progress of the work. In addition, the structure is stable and easy to assemble, and has certain practical value.

[0025] The specific operation is as follows: first, the foil washing water is injected into the recovery transfer tank 11 through the water injection pipe 13 and filled up. At the same time, the water pressure sensor 12 tests the water pressure in real time. When it is needed, the foil washing water in the recovery transfer tank 11 is introduced into the filter 2 through the drainage pipe 16 for filtration. Then, the foil washing water is transported to the place where it needs to be cleaned through the upward transport pipe 23. When the foil washing water level in the recovery transfer tank 11 drops to a certain level, the water pressure sensor 12 detects insufficient pressure and sends a command to the booster pump 17 to pressurize the foil washing water in the pipe to meet the demand for the foil washing water to flow in the upward transport pipe 23.

[0026] Please refer to the attached Figure 2 and attached Figure 3 The three water pressure sensors 12 and a water injection pipe 13 are equally spaced and distributed around the top of the recovery transfer tank 11. Since the foil washing water is fluid, such a distribution can improve the detection accuracy of the water pressure sensor 12. The top of the recovery transfer tank 11 is also provided with an opening 112, and the opening 112 is threadedly connected with a cover body 14. The other side of the bottom of the recovery transfer tank 11 is provided with a sewage outlet 113, and a faucet 15 is provided on the sewage outlet 113. Through the sewage outlet 113 and the faucet 15, the impurities precipitated in the recovery transfer tank 11 are discharged. The filter 2 includes a filter cartridge 21, and a bent pipe 22 is provided at the input end of the filter cartridge 21. The lower end of the bent pipe 22 is connected to the output end of the booster pump 17 through a flange. The filter 2 and the booster pump 17 are connected through the bent pipe 22. The output end of the filter cartridge 21 is provided with an upward transport pipe 23. The upward transport pipe 23 is used to transport the foil washing water upward. The circular holes at the input and output ends of the filter cartridge 21 are provided with pressure gauges 24. The pressure gauges 24 can be used to observe the water pressure changes passing through the filter 2 in real time, which is conducive to timely adjustment.

Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
