Description

Technical Field

[0001] This utility model relates to the technical field of pickling equipment, specifically to a pickling equipment for aluminum products. Background Technology

[0002] The main purposes of pickling aluminum products are as follows: First, to remove the surface oxide film. Aluminum products easily form an oxide film in the air, which pickling can remove, exposing the pure metal on the aluminum surface, facilitating subsequent processing. Second, to remove surface impurities such as oil, dust, and metal shavings, which can be effectively cleaned by pickling, improving surface cleanliness. Third, to improve surface roughness. Appropriate pickling can bring the surface roughness of aluminum products to a certain level, enhancing the adhesion of coatings and plating to the aluminum surface, and improving the corrosion resistance, wear resistance, and aesthetics of aluminum products, thereby meeting the needs of different application scenarios.

[0003] The existing Chinese utility model patent with publication number CN221192349U discloses an aluminum pickling device. This device includes an acid pickling tank, a reciprocating mechanism, a sliding frame, and a placement box. The reciprocating mechanism is installed on one side of the acid pickling tank, the sliding frame is located above the acid pickling tank, and the placement box is placed above the sliding frame. The acid pickling tank has evenly spaced roller grooves inside, with ball bearings inside each groove. A limiting seat is provided at the top of the acid pickling tank. This novel design assists the sliding frame in moving more effectively at the top of the acid pickling tank, effectively reducing friction at the bottom of the sliding frame and facilitating its movement. Furthermore, the limiting seat restricts the position of the sliding frame, preventing it from moving unnecessarily.

[0004] Currently, the aluminum pickling equipment in use still has the following problems:

[0005] After pickling, the surface of aluminum products is in an active state. If workers remove them directly, the surface treatment effect will be affected by the sweat and oil secretions on their hands. Furthermore, if the solution on the surface of the aluminum products is not rinsed off immediately, it will continue to react with the aluminum products, leading to excessive corrosion. Utility Model Content

[0006] The purpose of this invention is to provide an aluminum pickling device to solve the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0008] This utility model provides an aluminum pickling device, including a pickling cylinder, an inner immersion screen, and a cleaning cylinder. The pickling cylinder has a mesh inner immersion screen inside, and a cleaning cylinder of the same size is fixedly mounted on the top of the pickling cylinder. Side columns are fixedly installed on both sides of the inner immersion screen, and a solid circular base plate is connected to the bottom of the inner immersion screen. The midpoint of the surface of the side column is fixedly connected to a rod, and the rod is inserted into one end of the rod. One end of the rod is movably connected to a push rod, and the push rod is movably connected to the bottom of the hydraulic device.

[0009] A spray device is installed above the edge of the cleaning cylinder. One end of the spray device is connected to the spray head. The spray devices are interconnected in a ring by a connecting pipe. One side of the spray device is connected to the water inlet pipe. Multiple water outlets are opened in a ring at the bottom of the cleaning cylinder.

[0010] Preferably, the internal immersion screen is fixedly connected to a solid circular base plate via a connecting rod at the bottom edge, and the solid circular base plate is located inside the pickling cylinder, with grooves provided on both sides of the circular base plate.

[0011] Preferably, the hydraulic device is fixedly installed on both sides above the pickling cylinder, and a collar is installed below the push rod, and the collar is fixedly connected by a row rod and a column.

[0012] Preferably, the spray devices are connected by a connecting pipe, and a switch is installed on one side of the connecting pipe, with the spray head located inside the cleaning cylinder above.

[0013] Preferably, a drain outlet is provided on one side of the bottom of the pickling drum, and vibration motors are symmetrically fixedly installed on both sides of the pickling drum, and a drain ring is installed on the bottom edge of the cleaning drum.

[0014] Preferably, the internal immersion screen moves up and down inside the pickling and washing cylinders via a side column groove, and the circular bottom plate is located above the water outlet.

[0015] Preferably, the rod is installed inside the side column groove, and the side column groove is fixedly installed on the inner side of the pickling cylinder and the cleaning cylinder in a vertically intersecting arrangement.

[0016] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0017] 1. When aluminum products are pickled, the aluminum products can be immersed in the pickling drum through the inner immersion screen for pickling and soaking. A vibration motor is installed on the side of the pickling drum. The vibration motor vibrates the pickling drum, allowing the accumulated aluminum products to be gradually immersed into the inside of the pickling drum, improving the uniformity of cleaning. In addition, the vibration of the pickling drum can diffuse the acid into the clean water, improving the cleaning effect. Furthermore, the inner immersion screen moves up and down through a hydraulic device, allowing the cleaned aluminum products to be directly removed, avoiding contact between workers' hands and the aluminum products, thereby ensuring the stability of product quality.

[0018] 2. When aluminum products are being pickled, the inner immersion screen can be raised and lowered to the inside of the cleaning cylinder. The cleaning cylinder cleans the aluminum products through a spray device, which can quickly and continuously operate on the processed aluminum products. At the same time, it can terminate the pickling reaction, avoid corrosion caused by the acid continuing to act on the surface of the aluminum products, and shorten the waiting time in the middle of the pickling process, making it suitable for continuous production.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0029] Please see Figures 1-5 A pickling device for aluminum products includes a pickling drum 1, an inner immersion screen 4, and a cleaning drum 5. A drain outlet 2 is provided on one side of the bottom of the pickling drum 1, and a vibration motor 3 is symmetrically fixedly installed on both sides of the pickling drum 1. The pickling drum 1 is equipped with a mesh inner immersion screen 4. Side columns 41 are fixedly installed on both sides of the inner immersion screen 4, and a solid circular base plate 42 is connected to the bottom of the inner immersion screen 4. The inner immersion screen 4 is fixedly connected to the solid circular base plate 42 through a connecting rod 43 on the bottom edge, and the solid circular base plate 42 is located inside the pickling drum 1. Grooves are provided on both sides of the circular base plate 42.

[0030] The aluminum pickling device of this utility model has a mesh-like inner immersion screen 4, which allows the aluminum products inside to be completely immersed in the pickling cylinder 1. At the same time, the solid circular bottom plate 42 allows the inner immersion screen 4 to be isolated from the pickling cylinder 1 when the inner immersion screen 4 rises into the cleaning cylinder 5, so that the acid solution after cleaning can be discharged through the outlet 57 on one side of the circular bottom plate 42.

[0031] For details, please refer to the following: Figure 1 As shown, a cleaning cylinder 5 of the same size is fixedly mounted on the top of the pickling cylinder 1. A spraying device 51 is installed on the top edge of the cleaning cylinder 5. One end of the spraying device 51 is connected to the spray head 52. The spraying devices 51 are interconnected in a ring by a connecting pipe 56. One side of the spraying device 51 is connected to the water inlet pipe 55. Multiple water outlets 57 are opened in a ring at the bottom of the cleaning cylinder 5.

[0032] In this embodiment, a connecting pipe 53 is connected between the spray devices 51, and a switch 54 is installed on one side of the connecting pipe 53. The spray head 52 is located inside the cleaning cylinder 5 and above it. The inner immersion screen 4 moves up and down inside the pickling cylinder 1 and the cleaning cylinder 5 through the side column groove 75, and the circular bottom plate 42 is located above the water outlet 57.

[0033] The aluminum pickling device of this utility model has a spray head 52 that receives water through a spray device 51 and a water inlet pipe 55, and then the water flows between multiple spray heads 52 through a connecting pipe 56. This can effectively clean the aluminum products inside the inner immersion screen 4. This operation has strong continuity and can be directly treated with clean water after the equipment pickling to remove the acid from the surface of the aluminum products, prevent the acid from corroding the aluminum products excessively, and also prevent the pickling solution from re-entering the interior of the pickling cylinder 1.

[0034] For details, please refer to the following: Figure 4 and Figure 5 As shown, a drain ring 6 is installed on the bottom edge of the cleaning cylinder 5, the midpoint of the surface of the side column 41 is fixedly connected to the rod column 74, and the rod column 74 is inserted into one end of the row rod 73. The top of one end of the row rod 73 is movably connected to the push rod 71, and the push rod 71 is movably connected to the bottom of the hydraulic device 7.

[0035] In this embodiment, the hydraulic device 7 is fixedly installed on both sides above the pickling cylinder 1, and a collar 72 is installed below the push rod 71. The collar 72 is fixedly connected to the rod column 74 through the row rod 73. The rod column 74 is installed inside the side column groove 75, and the side column groove 75 is fixedly installed on the inner side of the pickling cylinder 1 and the cleaning cylinder 5 in a vertically intersecting arrangement.

[0036] The aluminum pickling device of this utility model uses hydraulic energy conversion to drive the push rod 71 and the push rod 73 to rise and fall, thereby causing the inner immersion screen 4 connected to the bottom of the rod column 74 to move up and down. When the inner immersion screen 4 is completely downward, the aluminum product is immersed in pickling. When the inner immersion screen 4 is upward, the aluminum product is directly lifted and removed. This reduces the transfer process of aluminum products after pickling, improves the processing efficiency of the equipment, avoids the danger caused by manual touch, and increases the stability of the product after pickling.

[0037] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
