Description

Technical Field

[0001] This utility model relates to the field of aluminum coil processing technology, specifically to an aluminum coil alkaline washing and degreasing cleaning machine. Background Technology

[0002] Aluminum coils are metal products that are rolled and bent on a casting and rolling mill before being sheared. After the aluminum coils are formed, due to the production process, certain substances will adhere to the surface of the aluminum coils. Therefore, after the aluminum coils are produced, a cleaning machine is needed to wash off the substances on the surface of the aluminum coils.

[0003] Existing aluminum coil alkaline degreasing cleaning machines guide the aluminum coils into the cleaning chamber via an uncoiler, and then use ultrasonic waves to clean the aluminum coils submerged in the cleaning solution. However, ultrasonic cleaning alone cannot ensure that other substances are completely removed, and some stains remain on the surface of the aluminum coils even after settling, failing to detach. Even after the aluminum coils are removed from the cleaning chamber, they still carry stains, which greatly affects the cleaning quality of the aluminum coils.

[0004] Therefore, in view of this, we have studied and improved the existing structure to propose an aluminum coil alkaline washing and degreasing cleaning machine. Utility Model Content

[0005] The purpose of this invention is to provide an aluminum coil alkaline washing and degreasing cleaning machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum coil alkaline washing and degreasing cleaning machine, comprising a cleaning chamber, an ultrasonic generator fixedly connected to the front side of the outer surface of the cleaning chamber, guide rollers rotatably connected to both ends of the upper surface of the cleaning chamber, a limit roller rotatably connected to the lower side of the inner surface of the cleaning chamber, a top cover fixedly connected to the middle of the upper surface of the cleaning chamber, a suction pump fixedly connected to the front side of the upper surface of the top cover, a conveying pipe fixedly connected to the front end of the suction pump, and nozzles fixedly connected to both ends of the top cover, the nozzles penetrating the top cover and connecting to the conveying pipe, and the nozzles being inclined downwards at a 45-degree angle.

[0007] Preferably, the upper surface of the top cover is fixedly connected to an inclined top by bolts, and an activated carbon filter element is installed on the inner surface of the inclined top, and the interior of the inclined top is connected to the lower side of the top cover.

[0008] Preferably, an air pump is fixedly connected to the upper surface of the sloping roof, and an exhaust pipe is fixedly connected to the rear end of the air pump.

[0009] Preferably, two small spray towers are fixedly installed on the rear side of the upper surface of the sloping top in a symmetrical arrangement, and the rear end of the exhaust pipe is fixedly connected to the lower side of the front surface of the small spray towers.

[0010] Preferably, an exhaust port is fixedly connected to the upper side of the rear surface of the small spray tower, and a sewage discharge port is connected to the lower rear surface of the small spray tower.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model utilizes an ultrasonic generator, guide rollers, limiting rollers, a top cover, a suction pump, a conveying pipe, and a nozzle. The aluminum coil, guided by an uncoiler, moves into the cleaning chamber by overlapping the upper surface of the left guide roller. Inside the cleaning chamber, the upper surface of the aluminum coil moves below the limiting roller. When the aluminum coil exits the cleaning chamber, it overlaps the upper surface of the right guide roller, forming a "U" shape inside the cleaning chamber. This allows for full immersion in the cleaning solution. The high-frequency sound waves generated by the ultrasonic generator ensure that the cleaning solution effectively cleans the aluminum coil. During the cleaning process, a suction pump draws up cleaning fluid and delivers it to each nozzle through a delivery pipe. The nozzles then perform high-pressure rinsing on the aluminum coils that have just entered the cleaning chamber and those that are about to leave the chamber, thus cleaning the aluminum coils again. The aluminum coils are ensured to be completely immersed in the cleaning fluid during cleaning. Through the three cleaning stages—pre-rinsing when the aluminum coils enter the cleaning chamber, ultrasonic cleaning inside the chamber, and rinsing again before the coils leave—the aluminum coils are thoroughly and effectively cleaned, greatly improving the cleaning quality.

[0013] 2. This utility model, through the arrangement of an inclined roof, a small spray tower, an air pump, and an exhaust pipe, allows the air pump to extract the waste gas and dust generated during the cleaning process from below the top cover during aluminum coil cleaning. When the waste gas and dust enter the inclined roof, they are first captured by the activated carbon filter inside the inclined roof, which adsorbs residual oil mist and volatile organic compounds. Then, the air pump transports the filtered waste gas through the exhaust pipe to the small spray tower. The small spray tower uses sulfuric acid solution to spray and neutralize the alkaline mist carried in the waste gas, which can fully and effectively purify and filter the waste gas pollution generated during the cleaning process, thereby preventing the waste gas from directly escaping into the working area and polluting the working environment.

An ultrasonic generator 2 is fixedly connected to the front of the outer surface of the cleaning chamber 1. Guide rollers 3 are rotatably connected to both ends of the upper surface of the cleaning chamber 1. Limiting rollers 4 are rotatably connected to the lower side of the inner surface of the cleaning chamber 1. A top cover 5 is fixedly connected to the middle of the upper surface of the cleaning chamber 1. A suction pump 6 is fixedly connected to the front side of the upper surface of the top cover 5. A conveying pipe 7 is fixedly connected to the front end of the suction pump 6. Nozzles 8 are fixedly connected to both ends of the top cover 5. The nozzles 8 penetrate the top cover 5 and are connected to the conveying pipe 7, and the nozzles 8 are inclined downward at a 45-degree angle.

[0020] By adopting the above technical solution, the aluminum coil is guided by the uncoiler and moves into the cleaning chamber 1 by being placed on the upper surface of the left guide roller 3. Inside the cleaning chamber 1, the upper surface of the aluminum coil moves below the limiting roller 4. When the aluminum coil is removed from the cleaning chamber 1, it will be placed on the upper surface of the right guide roller 3, so that the aluminum coil forms a "U" shape inside the cleaning chamber 1, thereby being fully immersed in the cleaning liquid inside the cleaning chamber 1.

[0021] The high-frequency sound waves generated by the ultrasonic generator 2 enable the cleaning fluid to thoroughly clean the aluminum coil.

[0022] The suction pump 6 draws out the cleaning fluid and delivers it to each nozzle 8 through the delivery pipe 7. The nozzle 8 performs high-pressure rinsing on the aluminum coils that have just entered the cleaning chamber 1 and the aluminum coils that are about to leave the cleaning chamber 1, thereby cleaning the aluminum coils again.

[0023] Furthermore, a sloping top 9 is fixedly connected to the middle of the upper surface of the top cover 5 by bolts, and an activated carbon filter element is installed on the inner surface of the sloping top 9, and the interior of the sloping top 9 is connected to the lower side of the top cover 5.

[0024] By adopting the above technical solution, the exhaust gas passing through the inclined top 9 will be adsorbed by the activated carbon filter to remove residual oil mist and volatile organic compounds.

[0025] Furthermore, an air pump 11 is fixedly connected to the upper surface of the sloping roof 9, and an exhaust pipe 12 is fixedly connected to the rear end of the air pump 11.

[0026] By adopting the above technical solution, the air pump 11 can draw the exhaust gas under the top cover 5 and filter it through the inclined top 9.

[0027] Furthermore, two small spray towers 10 are fixedly installed on the rear side of the upper surface of the sloping top 9 in a symmetrical arrangement, and the rear end of the exhaust pipe 12 is fixedly connected to the lower side of the front surface of the small spray tower 10.

[0028] By adopting the above technical solution, the air pump 11 will transport the filtered waste gas through the exhaust pipe 12 to the interior of the small spray tower 10, and the small spray tower 10 will use sulfuric acid solution to spray and neutralize the alkaline mist carried in the waste gas.

[0029] Furthermore, an exhaust port 13 is fixedly connected to the upper side of the rear surface of the small spray tower 10, and a sewage discharge port 14 is connected to the lower rear surface of the small spray tower 10.

[0030] By adopting the above technical solution, the purified gas will rise and be discharged through the exhaust port 13, and the waste liquid generated by the small spray tower 10 will be discharged through the sewage discharge port 14.

[0031] Working Principle: When using this aluminum coil alkaline washing and degreasing cleaning machine, the aluminum coil is first guided by the uncoiler and moves into the cleaning chamber 1 by overlapping the upper surface of the left guide roller 3. Inside the cleaning chamber 1, the upper surface of the aluminum coil moves below the limiting roller 4. When the aluminum coil moves out of the cleaning chamber 1, it overlaps the upper surface of the right guide roller 3, forming a "U" shape inside the cleaning chamber 1, thus ensuring full immersion in the cleaning solution. The high-frequency sound waves generated by the ultrasonic generator 2 ensure that the cleaning solution thoroughly cleans the aluminum coil. Simultaneously, the suction pump 6 draws the cleaning solution and delivers it to each nozzle 8 through the delivery pipe 7. The nozzles 8 perform high-pressure rinsing on the aluminum coil that has just entered the cleaning chamber 1 and the aluminum coil that is about to leave the cleaning chamber 1, thus cleaning the aluminum coil again. During the cleaning process, the aluminum coil is ensured to be completely immersed in the cleaning solution. The aluminum coil undergoes three cleaning stages: pre-rinsing upon entering the cleaning chamber 1, ultrasonic cleaning inside the cleaning chamber 1, and a final rinse before removal. These stages effectively clean the aluminum coil. During cleaning, the air pump 11 extracts the exhaust gas and dust generated below the top cover 5 via the inclined top 9. Upon entering the inclined top 9, the exhaust gas and dust are first captured by the activated carbon filter inside the inclined top 9, adsorbing residual oil mist and volatile organic compounds. Then, the air pump 11 delivers the filtered exhaust gas through the exhaust pipe 12 to the small spray tower 10. The small spray tower 10 uses sulfuric acid solution to spray and neutralize the alkaline mist carried in the exhaust gas, effectively purifying and filtering the exhaust gas pollution generated during the cleaning process. This prevents the exhaust gas from directly escaping into the working area and polluting the working environment. This is the working principle of the aluminum coil alkaline washing and degreasing cleaning machine.
