Description

Technical Field

[0001] This utility model relates to the field of electrode foil production technology, specifically to an acid cleaning device for electrode foil surface during production. Background Technology

[0002] In the production process of electrode foil for aluminum electrolytic capacitors, the electrode foil undergoes treatment in multiple acid baths with different compositions to obtain the largest possible surface area. Water washing tanks are installed between the different acid baths to clean the acid carried over from the foil surface, preventing interference between the components of different bath solutions and ensuring the electrode foil's surface area expansion. With the rapid development of production technology, the production speed of electrode foil processing has been continuously increasing, from the conventional 1.4 meters / minute to the current maximum production speed of 8 meters / minute. The ionic contamination of the foil surface due to acid has become increasingly apparent in the production process. Currently, the negative impact of acid contamination is usually mitigated by increasing the number of water washing tanks and increasing the cleaning spray volume. However, this treatment method produces a large amount of acidic wastewater, resulting in high wastewater treatment costs.

[0003] Therefore, it is necessary to propose an acid cleaning device for electrode foil production to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-3As shown, an acid cleaning device for electrode foil production includes two acid scraping rollers 1, which are staggered vertically. A material passage gap is provided between the roller surfaces of the two acid scraping rollers 1. Tension adjustment components are provided at both ends of one of the acid scraping rollers 1. The tension adjustment components are used to adjust the stagger distance between the two acid scraping rollers 1. The tension adjustment components include a slide block 5, which is rotatably connected to the acid scraping roller 1. The slide block 5 is slidably connected to a support 6 in the vertical direction. A lead screw 3 is provided on the support 6 to drive the slide block 5 to slide.

[0025] In use, it is placed above the liquid surface of the pickling tank 12. The pickled electrode foil is passed between the two acid scraping rollers 1. With the cooperation of the two acid scraping rollers 1, the acid liquid attached to the foil surface is squeezed back into the acid tank. In order to ensure that the acid scraping rollers 1 rotate with the foil surface and avoid scratching the foil surface due to asynchronous rotation between the acid scraping rollers 1 and the foil surface, the misalignment distance of the two acid scraping rollers 1 is adjusted by the tension adjustment component to control the foil surface tension and ensure the transmission effect between the electrode foil and the acid scraping rollers 1.

[0026] To prevent acid from corroding the acid scraping roller 1, the acid scraping roller 1 is made of glass.

[0027] One of the acid scraping rollers 1 is rotatably connected to the slide block 5 at both ends via ceramic bearings, and the other acid scraping roller 1 is rotatably connected to the bracket 6 at both ends via ceramic bearings. Ceramic bearings are used to avoid acid corrosion and ensure stable operation.

[0028] In some embodiments, the slide block 5 is slidably connected to the bracket 6 via a slide rod 4, and both ends of the slide rod 4 are fixedly connected to the bracket 6 via fixed seats 9. The slide rod 4 supports the slide block 5, enabling it to slide accurately along a preset direction and preventing positional deviation.

[0029] Specifically, a threaded sleeve 8 is fitted around the outer side of the lead screw 3, and the threaded sleeve 8 is fixedly connected to the fixed seat 9. The lead screw 3 is rotatably connected to the slide 5. A handle 7 is fixedly connected to the end of the lead screw 3 away from the slide 5. When it is necessary to adjust the misalignment distance between the two acid scraping rollers 1, the lead screw 3 is rotated by the handle 7. Under the interaction between the lead screw 3 and the threaded sleeve 8, the lead screw 3 slides along the axial direction of the slide 4, thereby driving the slide 5 to slide and realizing the adjustment of the misalignment distance between the two acid scraping rollers 1.

[0030] To facilitate fixing the position of the slide block 5, a slotted hole 10 is provided on the bracket 6 along the sliding direction of the slide block 5, and a through hole 11 is provided on the slide block 5 at the corresponding position of the slotted hole 10. The slide block 5 is fixedly connected to the bracket 6 by bolts. After the position is adjusted, the bolts are passed through the slotted hole 10 and the through hole 11 to lock the slide block 5 onto the bracket 6.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
