Description

Technical Field

[0001] This utility model relates to the field of copper strip processing equipment, specifically to a cleaning and passivation device for copper strips. Background Technology

[0002] After copper strip undergoes hot processing (such as rough rolling, intermediate rolling or finish rolling), it needs to be pickled to remove the residual oxide layer on the surface of the copper strip. After pickling, the copper strip needs to be washed with liquid and then put into a brushing box for cleaning and grinding. After that, the copper strip needs to be passivated and dried.

[0003] The patent, authorized by CN220941985U, is a Chinese utility model patent entitled "A Copper Strip Surface Brushing Equipment". The technical solution adopted in this patent document is to install a brushing device and a spraying device on a machine. The brushing device includes a first brushing device and a second brushing device for brushing the upper and lower surfaces of the copper strip. The spraying device includes three spraying zones, which are staggered and spaced apart from the first and second brushing devices. The spraying zone in the middle sprays liquid to rinse the copper strip surface, and the spraying zones at both ends spray liquid to rinse the brushing parts of the first and second brushing devices, respectively. However, in the above-mentioned rinsing equipment, the spraying area for the second brushing device to perform liquid cleaning may affect the rinsing effect because the spraying direction is opposite to the running direction of the copper strip; the function of the spraying area located between the first and second brushing devices may be limited, which may lead to increased resource consumption. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning and passivation device for copper strips. The device utilizes a first spraying device in the cleaning chamber, including a first spraying section and a second spraying section, to spray liquid towards the brushing parts of the first and second brushing devices, respectively. The second spraying device in the passivation chamber is used to spray passivating agent. By modifying the spraying device in the prior art, the cleaning efficiency is improved, resource consumption is reduced, and electricity is saved.

Detailed Implementation

[0020] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the relevant application and are not intended to limit the application. The described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0021] Example 1

[0022] See appendix Figure 1 and attached Figure 2 This embodiment is the basic technical solution that can achieve the purpose of this application.

[0023] The copper strip cleaning and passivation equipment includes a housing 1, which contains a cleaning chamber and a passivation chamber, and both sides of the housing 1 are provided with doors for easy maintenance. The cleaning chamber is equipped with a first brushing device 2, a second brushing device 3, and a first spraying device. The first brushing device 2 and the second brushing device 3 are used to brush the upper and lower surfaces of the copper strip, respectively. Specifically, the structure of the first brushing device 2 and the second brushing device 3 can be the same as that of the first brushing device and the second brushing device in CN220941985U, and they can be installed in the housing 1 (also called the chassis) in the same way. They can also use the same driving method. This part of the technical solution is the prior art, so it will not be described in detail.

[0024] The first spraying device includes a first spraying section 4 and a second spraying section 5 that are interconnected. The first spraying section 4 sprays liquid towards the brushing area of ​​the first brushing device 2 and the second spraying section 5 sprays liquid towards the brushing area of ​​the second brushing device 3. Preferably, the first spraying section 4 is located upstream of the first brushing device 2 and towards the brushing area of ​​the first brushing device 2; the second spraying section 5 is located between the first brushing device 2 and the second brushing device 3 and towards the brushing area of ​​the second brushing device. The cleaning liquid sprayed by the first spraying section 4 and the second spraying section 5, which are arranged in this way, can enter the brushing area of ​​the first brushing device 2 or the second brushing device 3 along with the moving direction of the copper strip, resulting in a better rinsing effect.

[0025] A second spraying device is installed in the passivation chamber. The second spraying device includes a third spraying section. The third spraying section is used to spray passivating agent onto the copper strip after it has been brushed by the first brushing device 2 and the second brushing device 3. The passivating agent here can be benzotriazole passivating agent, so as to prevent the copper surface exposed to the atmosphere from gradually discoloring over time.

[0026] The aforementioned first spray section 4, second spray section 5, and third spray section can have the same structure. Each of them independently includes a pair of spray pipes arranged on both sides of the copper strip. Each pair of spray pipes is connected by a connecting pipe 14. The spray pipes should be provided with a number of spray heads. The specific structure, shape, and connection form of the spray pipes and the connecting pipe 14 can be found in the arrangement of the spray pipes and square tubes in CN220941985U. Furthermore, since both the first spray section 4 and the second spray section 5 spray out cleaning fluid, the connecting pipes 14 of the first spray section 4 and the second spray section 5 can be connected to each other. Specifically, the form of a manifold as described in CN220941985U can be used to connect the connecting pipes 14 of the first spray section 4 and the second spray section 5 to each other, thereby forming the first spray device.

[0027] In order to enable the cleaning fluid sprayed from the first spray section 4 and the second spray section 5 to be recycled, this embodiment can be further improved as follows: The bottom of the cleaning chamber and the passivation chamber are respectively provided with liquid storage chambers. The liquids in the cleaning chamber and the passivation chamber should be isolated from each other to prevent the cleaning liquid and the passivating agent from mixing. Specifically, a first partition wall 8 can be provided in the housing 1. The first partition wall 8 is used to divide the inner cavity of the housing 1 into a cleaning chamber and a passivation chamber where the liquids are isolated from each other, thereby preventing the cleaning liquid and the passivating agent from mixing. However, a channel for the copper strip to pass through should be provided on the first partition wall 8. The housing 1 is provided with a first pump body 6 and a second pump body 7, wherein the liquid inlet end of the first pump body 6 is connected to the liquid storage chamber of the cleaning chamber, and the liquid outlet end is connected to the first spraying device; the liquid inlet end of the second pump body 7 is connected to the liquid storage chamber of the passivation chamber, and the liquid outlet end is connected to the second spraying device; it is used to provide the first spraying device and the second spraying device with the cleaning liquid or passivating agent required by each of them.

[0028] Example 2

[0029] See appendix Figure 3 and attached Figure 4 Based on the above embodiment 1, this embodiment adds a drying chamber for drying copper strips.

[0030] Before the copper strip enters the drying chamber, it is best to install several pairs of rubber rollers 9 in the passivation chamber; each rubber roller 9 is supported on the housing 1 and located on the upper and lower sides of the copper strip, and is used to squeeze out the passivating agent attached to the copper strip; thereby reducing the burden on the drying chamber.

[0031] The drying chamber is located inside the housing 1. Specifically, the passivation chamber is located between the cleaning chamber and the drying chamber, and the liquids in the passivation chamber and the drying chamber should be isolated from each other. The drying chamber is equipped with multiple heating tubes 10 for drying copper strips. These heating tubes 10 are each supported on the housing 1 and located on both sides of the copper strip, respectively, for heating and drying the copper strip. As for the method of isolating the liquids in the passivation chamber and the drying chamber, a second partition wall 11 can be provided inside the housing 1. The second partition wall 11 is used to divide the inner cavity of the housing 1 into a passivation chamber and a drying chamber where the liquids are isolated from each other. The second partition wall 11 should be provided with a channel for the copper strip to pass through.

[0032] In order to enhance the drying effect of the drying chamber and prevent the temperature inside the drying chamber from being too high, the shell 1 corresponding to the drying chamber is preferably equipped with a blower 12 and an air outlet 13. The blower 12 is used to blow air into the drying chamber, and the air from the blower 12 is discharged from the air outlet 13.

"And" and "or" in this article are merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and or B can mean: A exists alone, A and B exist simultaneously, and B exists alone.

[0034] It should be noted that, for ease of description, only the parts relevant to the application are shown in the accompanying drawings; unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
