Description

Technical Field

[0001] This utility model relates to the field of battery foil processing, and in particular to a battery foil surface degreasing device. Background Technology

[0002] The degreasing device is an industrial equipment specifically designed to remove residual oil stains such as rolling oil from the surface of battery foil, especially aluminum foil. By integrating physical, chemical or physicochemical composite processes, it emulsifies, peels off, separates and removes residual oil stains on the surface during the continuous conveying of battery foil. At the same time, it ensures the flatness and structural integrity of the battery foil surface, and ultimately meets the stringent requirements of subsequent battery foil processing for surface cleanliness, conductivity and coating adhesion. It is a key pretreatment equipment in the battery foil production chain to ensure product quality.

[0003] In the prior art, compared with the Chinese utility model with announcement number CN219520042U, an aluminum foil surface degreasing device is disclosed, which cleans the aluminum foil surface with an adjustable brush. However, in actual use, it has been found that because the grease brushed off the aluminum foil surface is relatively light, it will float on the water surface after cleaning. If it cannot be isolated and recycled, it will often adhere to the aluminum foil surface at the discharge port, causing secondary pollution. Utility Model Content

[0004] The purpose of this invention is to provide a device for removing oil from the surface of battery foil in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A battery foil surface degreasing device includes guide rollers for transmission and an ultrasonic cleaning mechanism for cleaning.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1-6 As shown, a battery foil surface degreasing device includes a guide roller 6 for transmission and an ultrasonic cleaning mechanism 2 for cleaning. Several guide rollers 6 are arranged along the cleaning trajectory of the battery foil 5 inside the ultrasonic cleaning mechanism 2. It also includes a preliminary cleaning mechanism 1 for preliminary cleaning of the battery foil 5, an oil removal mechanism 3 for removing grease floating on the water surface, and a return mechanism 4. The preliminary cleaning mechanism 1 is installed at the upper inlet of the ultrasonic cleaning mechanism 2, the oil removal mechanism 3 is installed near the outlet of the ultrasonic cleaning mechanism 2, and the return mechanism 4 is installed on the side wall of the ultrasonic cleaning mechanism 2.

[0029] The oil removal mechanism 3 includes an oil receiving box 31 and a buffer assembly 32. The oil receiving box 31 is installed inside the cleaning chamber 21 of the ultrasonic cleaning mechanism 2. The height of the baffle at the incoming end of the oil receiving box 31, i.e., the low baffle, is smaller than the height of the baffle at the outgoing end, i.e., the high baffle. A collection trough 33 is installed at the front end of the oil receiving box 31. Both ends of the oil receiving box 31 are connected to the side wall of the cleaning chamber 21 through the buffer assembly 32. A bottom funnel 35 is provided at the bottom of the oil receiving box 31. An air bladder 34 is installed at the bottom of the bottom funnel 35. The liquid outlet of the bottom funnel 35 is connected to the return mechanism 4 through the discharge pipe 36.

[0030] The return mechanism 4 includes a central box 41, which is installed on the outside of the side wall of the cleaning box 21. An overflow port 47 is provided on the side wall of the cleaning box 21. A filter plate 42 is installed inside the central box 41. The oily water is treated and returned to the cleaning box 21 through the circulation component via the water outlet pipe 43 at the bottom of the central box 41.

[0031] In this embodiment, the bottom edge of the overflow port 47 is higher than the highest position of the low baffle on the oil receiving box 31. When the backflow water from the cleaning nozzle 12 and the return mechanism 4 raises the water level inside the cleaning tank 21, the overflow port 47 is used to treat the excessively high water level to prevent overflow. In addition, the height of the high baffle of the oil receiving box 31 is greater than the height of the overflow port 47 to prevent oil from overflowing to the discharge side.

[0032] In this embodiment, the circulation component includes an outlet pipe 43, a filter box 44, a return water pump 45, and a return pipe 46. The outlet pipe 43 connects the collection box 41 and the filter box 44. The outlet of the filter box 44 is connected to the inlet of the return water pump 45. The outlet of the return water pump 45 is connected to the return pipe 46. The outlet of the return pipe 46 is located at the bottom of the cleaning tank 21, which returns the filtered cleaning liquid to the cleaning tank 21 to ensure the water level inside the cleaning tank 21.

[0033] In this embodiment, the preliminary cleaning mechanism 1 includes a splash shield 11, a cleaning nozzle 12, and a feed inlet 13. The splash shield 11 is fixed to the upper end of the cleaning box 21. The cleaning nozzle 12 is horizontally installed inside the splash shield 11. The feed inlet 13 for passing through the battery foil 5 is formed on the splash shield 11. The cleaning box 21 uses pressurized water to perform preliminary rinsing of the battery foil 5 to improve the cleaning effect.

[0034] In this embodiment, an ultrasonic generator 22 is provided at the bottom of the cleaning tank 21. The ultrasonic generator 22 is fixed to the cleaning tank 21, and the installation height of the ultrasonic generator 22 is lower than that of the guide roller 6 located at the bottom of the cleaning tank 21.

[0035] In this embodiment, the buffer assembly 32 includes a side fixing frame 321, a connecting frame 322, a piston 323, and a through hole 324. The lower half of the side fixing frame 321 and the cleaning tank 21 form a closed space. A through hole 324 is provided at the center of the bottom of the side fixing frame 321. The piston 323 is slidably connected to the closed space of the side fixing frame 321. The upper end of the piston 323 is connected to the oil receiving box 31 through the connecting frame 322. When the oil receiving box 31 changes height under the buoyancy of the airbag 34, in order to avoid the oil receiving box 31 from rising and falling too quickly, a small through hole 324 is used to limit the liquid flow speed inside the connecting frame 322, thereby providing damping for the rise and fall of the oil receiving box 31. This ensures the recovery of oil and avoids excessive water surface fluctuations caused by excessively rapid rise and fall, which would cause oil to splash up.

[0036] In this embodiment, the collection tank 33 is made of rubber, and the discharge pipe 36 located inside the cleaning tank 21 is an elastic telescopic pipe structure.

[0037] Working principle: When cleaning the battery foil 5, the battery foil 5 is supported by the guide roller 6 and first passes through the bottom of the cleaning nozzle 12. The battery foil 5 is rinsed by the pressure cleaning fluid and then enters the cleaning tank 21. It is immersed in the cleaning fluid and is cleaned by the ultrasonic generator 22 and the cleaning fluid.

[0038] After the lubricating oily substances on the battery foil 5 are washed away, they float above the cleaning liquid. At this time, the oil film formed by the oil will sway back and forth. The oil receiving box 31, located on the side of the discharge port, is lower and slowly collects the oil floating on the surface. It is then collected through the bottom funnel 35 and returned to the external collection box 41 through the discharge pipe 36. After preliminary filtration by the filter plate 42, it enters the filter box 44 through the water outlet pipe 43 for further treatment. Then, it is returned to the cleaning box 21 through the return water pump 45 and the return pipe 46. When the oil receiving box 31 changes height under the buoyancy of the air bag 34, a small through hole 324 is used to limit the flow speed of the liquid inside the connecting frame 322 in order to prevent the oil receiving box 31 from rising and falling too quickly. This provides damping for the rise and fall of the oil receiving box 31, which can ensure the recovery of the oil and prevent the water surface from undulating too much due to the rapid rise and fall, causing the oil to splash.

[0039] All electronic components mentioned in this article are electrically connected to an external main controller and 220V AC mains power. The main controller can be a conventional, known device such as a computer. The electronic components, along with their associated control systems, power supply modules, circuits, and piping, can be provided by the manufacturer. Furthermore, all electronic components and control modules involved in this invention are existing technologies, fully capable of being implemented by those skilled in the art, and require no further explanation. This invention does not involve any improvement to the structure or usage of the electronic components.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
