Description

Technical Field

[0001] This invention belongs to the field of chemical metal surface treatment technology, and relates to an oil removal device for aluminum strip coils. Background Technology

[0002] Aluminum strip coils are an important industrial material widely used in many fields, such as aerospace, automobile manufacturing, and building decoration. Surface degreasing is a crucial step in the production and processing of aluminum strip coils, its purpose being to remove oil and impurities from the surface of the aluminum strip coils to ensure product quality and performance.

[0003] However, current methods for degreasing aluminum strip coils present a series of problems. First, traditional degreasing methods are inefficient and cannot meet the needs of large-scale production. Second, the degreasing effect is unsatisfactory, easily leaving oil residues that affect subsequent processing and use of the aluminum strip coils. Third, existing degreasing equipment may damage the surface of the aluminum strip coils, reducing product quality. Furthermore, the equipment consumes a lot of energy, increasing production costs and potentially causing environmental pollution.

[0004] Currently, there are several main solutions:

[0005] New types of chemical degreasing agents are used: These degreasing agents can improve degreasing efficiency, but may pose risks of chemical residues and environmental pollution.

[0006] For example, while increasing the degreasing speed, strict wastewater treatment measures are required; the structure of physical degreasing equipment can be optimized: by improving the equipment structure of physical degreasing methods such as scraping and wiping, damage to the surface of aluminum strip can be reduced, but incomplete degreasing may still occur; physical degreasing equipment, although reducing surface damage, has limited effectiveness in removing stubborn oil stains; or multiple degreasing methods can be combined: combining chemical degreasing and physical degreasing to improve the degreasing effect, but this increases the complexity of the equipment and raises maintenance costs.

[0007] Taking into account the advantages and disadvantages of the above solutions, this utility model aims to provide an innovative aluminum strip coil surface degreasing device that can improve degreasing efficiency and effect, reduce damage to the aluminum strip coil surface, reduce equipment energy consumption and maintenance costs, and avoid environmental pollution. Summary of the Invention

[0008] This invention provides an aluminum strip coil surface degreasing device to solve the problem of surface damage during aluminum strip coil degreasing, reduce costs, and avoid environmental pollution.

[0009] To solve the above problems, the technical solution adopted by the invention is as follows:

[0010] An aluminum strip surface degreasing device includes a heating zone with multiple conveying rollers and heating devices on the upper and lower sides of the conveying rollers; a cleaning zone with multiple rotating rollers and cleaning nozzles between the rotating rollers, the cleaning nozzles being connected to a cleaning device on one side of the cleaning zone; a wiping zone with wiping areas at the upper and lower ends of the aluminum strip; and a collection box at the lower end of the wiping zone.

[0011] The principle behind this solution is:

[0012] Multiple conveyor rollers in the heating zone ensure the aluminum strip is transported smoothly forward. Heating devices on the top and bottom sides heat the strip, softening or increasing the fluidity of oil on its surface, preparing it for subsequent cleaning. Multiple rotating rollers maintain stable strip transport, while cleaning nozzles spray cleaning fluid to rinse the heated strip. A bottom circulation pump returns used cleaning fluid to the cleaning unit via a circulation pipe, achieving resource recycling and cost reduction. After cleaning, the strip reaches the wiping zone, where it is further wiped at both ends to remove residual oil and cleaning fluid, ensuring the strip's surface cleanliness meets requirements. Finally, a collection box at the bottom of the wiping zone collects oil, cleaning fluid, and impurities generated during wiping for convenient and environmentally friendly processing.

[0013] The beneficial effects of this solution are:

[0014] Multiple conveyor rollers ensure smooth transport of the aluminum strip during heating, preventing jamming or deviation. Heating devices on both the top and bottom sides provide omnidirectional heating, ensuring thorough heating of oil stains and reducing their stickiness and adhesion. This preheating process not only improves degreasing efficiency but also reduces reliance on strong detergents or high-pressure rinsing during cleaning, thus minimizing the risk of damage to the aluminum strip surface. Multiple rotating rollers guarantee stable transport of the aluminum strip during cleaning, allowing the cleaning nozzles to accurately and evenly rinse the strip. The connection between the cleaning nozzles and the cleaning device ensures a sufficient and stable supply of cleaning fluid, enabling rapid and effective removal of loosened oil stains after heating. This step not only improves the thoroughness of degreasing but also reduces the amount of cleaning fluid used due to efficient cleaning, lowering costs and potential environmental impact. Wiping areas at both ends of the aluminum strip provide a final fine treatment, removing any remaining trace amounts of oil and moisture.

[0015] Furthermore, the wiping area is fixedly set at both ends of the aluminum strip, and the wiping direction of the wiping area is perpendicular to the moving direction of the aluminum strip. Since the wiping direction is perpendicular to the moving direction of the aluminum strip, the wiping action can form a "cutting" effect, which can better break the adhesion between oil and impurities and the surface of the aluminum strip, thereby achieving a more thorough cleaning. This vertical setting can also make the wiping force distribution more uniform, avoiding the situation of insufficient or excessive wiping in some areas due to the wiping direction being the same as the moving direction of the aluminum strip, thus ensuring the cleaning quality of the aluminum strip surface.

[0016] Furthermore, the wiping area includes a mounting frame, support frames, a conveyor belt, a sponge, and a motor. The mounting frame is fixedly mounted on the base, and four support frames are mounted on the mounting frame. The conveyor belt is mounted on the support frames and connected to the support frames via rotating rods. A motor is mounted on the support frames, and the output shaft of the motor is fixedly connected to the rotating rods. The mounting frame is fixed to the base to ensure that there is no shaking or displacement during the wiping process, thereby ensuring the accuracy and stability of the wiping. The four support frames increase the support points of the conveyor belt, allowing the conveyor belt to remain stable during operation and evenly bear the wiping pressure. The output shaft of the motor is fixedly connected to the rotating rods, ensuring the accuracy and timeliness of power transmission, and enabling rapid response and adjustment of the conveyor belt's running speed to adapt to different production needs and the movement speed of the aluminum strip.

[0017] Furthermore, the sponge installed on the conveyor belt is a graphene sponge, which is fixedly connected to the conveyor belt. The graphene sponge has adsorption properties, which can effectively adsorb oil stains on the surface of the aluminum belt, improving the oil removal effect and efficiency. The graphene sponge has good flexibility and elasticity, and when it is fixedly connected to the conveyor belt and wiped, it can adapt well to the shape and texture of the aluminum belt surface without scratching or damaging the aluminum belt surface, effectively protecting the surface quality of the aluminum belt.

[0018] Furthermore, a scraper is provided at the lower end of the conveyor belt. The scraper is fixedly positioned in contact with the sponge via an adjustable rod. The scraper can remove oil and impurities adsorbed by the sponge after wiping the aluminum belt, which helps maintain the cleanliness and adsorption performance of the sponge, enabling it to continuously and efficiently perform wiping work. This extends the effective service life of the sponge, reduces the need for frequent sponge replacement, and lowers costs. At the same time, the adjustable feature allows for control of the contact pressure and angle between the scraper and the sponge according to actual conditions, providing good flexibility.

[0019] Furthermore, the cleaning nozzle is a high-pressure cleaning nozzle with a rotatable structure. The high-pressure water flow can generate a powerful impact force, quickly breaking down and removing stubborn oil and impurities on the surface of the aluminum strip, greatly improving the cleaning efficiency and quality. The rotatable design allows the high-pressure water flow to cover a wider area, avoiding the occurrence of cleaning dead corners.

[0020] Furthermore, the heating device is an electromagnetic heating device. Compared with traditional heating methods, electromagnetic heating can directly act on the heated object, has a high energy conversion rate, greatly reduces energy loss, and thus reduces the operating cost of the equipment. It can quickly raise the temperature of the aluminum strip, making the oil stains soften or evaporate faster, shortening the time of the entire degreasing process, and improving production efficiency.

[0021] Furthermore, a first baffle and a second baffle are fixedly installed at the inlet and outlet ends of the cleaning zone near the heating zone. The baffles are sponge baffles. Installing baffles at the inlet and outlet ends of the cleaning zone near the heating zone can effectively prevent the cleaning liquid and water vapor in the cleaning zone from spreading to the heating zone. The sponge baffles can also reduce the splashing and evaporation of the cleaning liquid in the cleaning zone, which helps to maintain a clean and safe working environment and reduce the risk of operators coming into contact with chemicals.

[0022] Furthermore, the second baffle is tilted and offset, so that the baffle and the outlet end of the cleaning zone form an angle. The tilted baffle can also enhance the blocking effect on cleaning fluid and impurities. Since the baffle and the outlet end of the cleaning zone form an angle, when the cleaning fluid and impurities encounter the baffle, they will flow along the tilted surface in a specific direction, instead of splashing directly or flowing back to the outlet of the cleaning zone, thereby effectively reducing the overflow of cleaning fluid and impurities.

[0027] The reference numerals in the accompanying drawings include: heating zone 1, cleaning zone 2, wiping zone 3, collection box 4, heating device 5, rotating roller 6, cleaning nozzle 7, circulating pump 8, circulating pipe 9, cleaning device 10, mounting bracket 11, support bracket 12, motor 13, scraper 14, adjusting rod 15, conveying roller 16, sponge 17, conveyor belt 18, rotating rod 19, inlet end 20, outlet end 21, first baffle 22, and second baffle 23.

[0028] The basic implementation examples are as follows: Figure 1-4 As shown, an aluminum strip surface degreasing device includes a heating zone 1, a cleaning zone 2, and a wiping zone 3. Multiple conveying rollers 16 are arranged in the heating zone 1, and heating devices 5 are arranged on the upper and lower sides of the conveying rollers 16. The heating devices 5 are electromagnetic heating devices, which can raise the temperature of the aluminum strip, softening the oil stains on the surface of the aluminum strip and reducing its stickiness and adhesion. Furthermore, the heating process not only improves the efficiency of subsequent cleaning but also reduces reliance on strong cleaning agents or high-pressure rinsing, lowering the risk of damage to the aluminum strip surface.

[0029] A cleaning zone 2 is located at the inlet end 20 of the heating zone 1. Multiple rotating rollers 6 are installed within the cleaning zone 2, and high-pressure cleaning nozzles 7 are positioned between the rollers 6. The cleaning nozzles 7 are rotatable and capable of rinsing the aluminum strip. The cleaning nozzles 7 are connected to a cleaning device 10 located on one side of the cleaning zone 2. The cleaning device 10 stores cleaning fluid. During the cleaning process, the powerful water jets from the high-pressure cleaning nozzles 7 remove oil and impurities from the surface of the aluminum strip. The rotatable design ensures thorough cleaning without dead angles, improving cleaning efficiency and quality. Simultaneously, a circulation pump 8 and circulation pipe 9 are installed at the bottom of the cleaning zone 2 to return the used cleaning fluid to the cleaning device 10 for recycling, reducing the amount of cleaning fluid used and lowering costs and environmental impact.

[0030] The outlet end 21 of the cleaning device 10 is provided with a wiping area 3, which is fixedly set at the upper and lower ends of the aluminum strip. The wiping direction is perpendicular to the moving direction of the aluminum strip. The wiping area 3 includes a mounting frame 11, a support frame 12, a conveyor belt 18, a sponge 17, and a motor 13. The mounting frame 11 is fixed on the base, and four support frames 12 are set on the mounting frame 11, which increases the support points of the conveyor belt 18 and makes the conveyor belt 18 run smoothly. A graphene sponge 17 is fixedly connected to the conveyor belt 18. The graphene sponge 17 has excellent adsorption performance and can efficiently adsorb residual oil stains on the surface of the aluminum strip. The conveyor belt 18 and the support frame 12 are connected by a rotating rod 19. The output shaft of the motor 13 on the support frame 12 is fixedly connected to the rotating rod 19, which ensures the accuracy and timeliness of power transmission and can quickly adjust the running speed of the conveyor belt 18 according to production needs and the moving speed of the aluminum strip. A scraper 14 is provided at the lower end of the conveyor belt 18. The scraper 14 is fixedly positioned in contact with the sponge 17 via an adjustable rod 15. The scraper 14 can promptly scrape off the oil and impurities adsorbed by the sponge 17, maintaining the cleanliness and adsorption performance of the sponge 17, extending its effective service life, and reducing costs. At the same time, the adjustable rod 15 allows for flexible control of the contact pressure and angle between the scraper 14 and the sponge 17 according to actual conditions, ensuring optimal wiping effect.

[0031] A collection box 4 is installed at the lower end of the wiping area 3 to collect oil, cleaning fluid and impurities generated during the wiping process, so as to facilitate subsequent unified treatment and avoid environmental pollution.

[0032] In addition, a first baffle 22 and a second baffle 23 are fixedly installed in the cleaning zone 2 near the inlet end 20 and outlet end 21 of the heating zone 1. The baffles are made of sponge 17. The first baffle 22 can prevent the cleaning liquid and water vapor in the cleaning zone 2 from diffusing to the inlet end 20 of the heating zone 1, protecting the equipment in the heating zone 1 from corrosion. The second baffle 23 is inclined and offset, forming an angle with the outlet end 21 of the cleaning zone 2. This inclined design enhances the blocking effect on the cleaning liquid and impurities, causing the cleaning liquid and impurities to flow in a specific direction along the inclined surface, reducing spillage and maintaining a clean working environment.
