Description

Technical Field

[0001] This utility model relates to the field of aluminum processing technology, specifically to a device for removing oil stains from billets. Background Technology

[0002] In the aluminum processing industry, billets are usually covered with oil stains before processing. These oil stains may come from the storage and transportation process of the billets, or from the characteristics of the raw materials themselves. The presence of oil stains can seriously affect subsequent processing technology. For example, in rolling and forging processes, oil stains may cause accelerated wear of processing equipment, affect processing accuracy, and may also form defects on the product surface, reducing product quality. Therefore, it is crucial to effectively remove oil stains from aluminum billets. Currently, the common existing technologies for removing oil stains from aluminum billets are mainly as follows: The first is solvent cleaning, which involves immersing the aluminum billet in an organic solvent and using the solvent's dissolving effect to remove the oil stains. During operation, the billet is completely immersed in a container containing an organic solvent (such as gasoline, trichloroethylene, etc.). After soaking for a period of time, it is removed and wiped dry with a clean cloth or simply rinsed. The second is alkaline cleaning, which involves preparing an alkaline cleaning solution of a certain concentration and placing the aluminum billet in the solution. The alkaline substances react with the oil stains through a saponification reaction, causing the oil stains to decompose and detach from the surface of the billet. Generally, heated alkaline cleaning solutions are used to accelerate the reaction. After cleaning, the billet is rinsed with clean water. However, existing technologies have obvious drawbacks. During soaking and cleaning, the cleaning solution flows slowly and cannot strongly wash the billet, making it difficult to effectively remove stubborn oil stains. Moreover, during soaking, the cleaning solution has the same effect on all parts of the billet, making it impossible to target heavily oiled areas for cleaning, resulting in inconsistent cleaning effects. Although spray cleaning can generate a certain impact force, the nozzle position is fixed and the spray angle is limited. For some complex structures of the billet, such as grooves and corners, the cleaning solution has difficulty reaching them, and oil stains are easy to remain. Manual wiping is not only inefficient and consumes a lot of labor costs, but also cannot guarantee the consistency of cleaning quality due to different operating techniques and force of workers. Therefore, we propose a billet degreasing device. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a billet degreasing device that can more effectively remove oil stains from various parts of the aluminum billet surface, thus effectively solving the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a billet degreasing device, comprising a housing, an inlet pipe at the inlet of the front end of the housing, an outlet pipe at the outlet of the front end of the housing, and a degreasing component; The cleaning assembly includes a cleaning frame, a blank holder, and brushes. The cleaning frame is rotatably connected to the bottom wall of the outer shell, and the central axis of the cleaning frame does not coincide with that of the outer shell. The blank holder is rotatably connected to the bottom wall of the cleaning frame. The inner wall of the cleaning frame is provided with evenly distributed brushes. The eccentric rotation of the cleaning frame causes the cleaning liquid to strongly wash the aluminum blank. The revolution and rotation of the blank holder cause the brushes to clean the aluminum blank in all directions, solving the problems of incomplete soaking and spray cleaning and inconsistent quality of manual wiping.

[0005] Furthermore, a control switch assembly is provided on the front side of the housing, and the input end of the control switch assembly is electrically connected to an external power source for stable control.

[0006] Furthermore, the cleaning assembly also includes a lower pressure plate and bolts. Guide grooves are provided on the upper ends of the left and right inner walls of the billet rack. The lower pressure plate is slidably connected between the two guide grooves. A bolt is threadedly connected to the upper right side of the billet rack. The lower end of the bolt is rotatably connected to the upper side of the lower pressure plate to clamp the aluminum billet.

[0007] Furthermore, the cleaning assembly also includes a protective plate and a rotating shaft. The upper end of the inner arc surface of the outer shell is provided with a perforated plate, and the top wall of the outer shell is equipped with a mounting plate via a mounting post. The outer arc surface of the mounting plate and the inner arc surface of the perforated plate are both provided with sliding grooves. A protective plate is slidably connected between the two sliding grooves. The left end of the protective plate is rotatably connected to a rotating shaft. The lower end of the rotating shaft passes through the upper side wall of the cleaning frame and is fixedly connected to the upper side of the blank rack. The protective plate reduces the splashing of cleaning liquid during the cleaning process.

[0008] Furthermore, the cleaning assembly also includes a gear and an internal gear ring. The upper side of the perforated plate is provided with an internal gear ring, and the upper end of the rotating shaft is provided with a gear. The gear meshes with the internal gear ring, causing the blank holder to rotate.

[0009] Furthermore, a main shaft is rotatably connected to the top wall of the outer casing. The lower end of the main shaft passes through the middle of the mounting plate and is fixedly connected to the upper side of the cleaning frame. The main shaft does not coincide with the central axis of the cleaning frame. A motor is installed on the upper side of the outer casing. The output shaft of the motor is fixedly connected to the center of the upper end face of the main shaft. The input end of the motor is electrically connected to the output end of the control switch group for stable driving.

[0010] Furthermore, a material inlet chamber is provided at the inlet and outlet of the front side wall of the outer shell. A material door is hinged to the front end of the material inlet chamber via a hinge. Guide grooves are provided at the front end of the upper side wall of the outer shell and the front end of the perforated plate. A baffle is slidably connected between the two guide grooves. The front side of the baffle is slidably connected to the inner arc surface of the outer shell. The baffle is configured to cooperate with the inlet and outlet. An electric cylinder is installed on the upper side of the outer shell. The telescopic end of the electric cylinder is fixedly connected to the upper rear side of the baffle. The input end of the electric cylinder is electrically connected to the output end of the control switch group to prevent the cleaning fluid from leaking out through the material door.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This billet degreasing device has the following advantages: The cleaning frame is not aligned with the central axis of the outer casing, and rotates eccentrically under the drive of the motor. The resulting centrifugal force causes the cleaning fluid to flow irregularly, enhancing the rinsing effect on the billet. Simultaneously, the billet rack revolves under the drive of the cleaning frame and rotates on its own axis through the meshing of gears and an internal gear ring. This allows the aluminum billet to contact the brushes from all directions, enabling a more thorough cleaning of the billet surface. Compared to traditional cleaning methods, this method more effectively removes oil stains from various parts of the aluminum billet surface, solving the problems of incomplete soaking and spraying cleaning, and inconsistent quality and easy damage from manual wiping. The cleaning effect is significantly improved. Attached Figure Description

[0015] Please see Figure 1-6This embodiment provides a technical solution: a billet degreasing device, including a housing 1. A control switch group 15 is provided on the front side of the housing 1. The input terminal of the control switch group 15 is electrically connected to an external power source.

A guide groove 8 is provided, and a baffle 7 is slidably connected between two guide grooves 8. The front side of the baffle 7 is slidably connected to the inner arc surface of the outer shell 1. The baffle 7 is configured to cooperate with the inlet and outlet 9. An electric cylinder 13 is installed on the upper side of the outer shell 1. The telescopic end of the electric cylinder 13 is fixedly connected to the upper rear side of the baffle 7. The input end of the electric cylinder 13 is electrically connected to the output end of the control switch group 15. First, the liquid inlet pipe 10 is connected to the external cleaning liquid storage tank and the circulation pump, and the discharge pipe 11 is connected to the external filter device and the cleaning liquid storage tank. Then, the control switch group 15 is operated to make the electric cylinder 13 operate. The telescopic end of the electric cylinder 13 pushes the baffle 7 upward. As the baffle 7 moves upward, it gradually moves away from the inlet and outlet 9 to clean the aluminum billet. It also includes a decontamination component 2. Decontamination assembly 2 includes a cleaning frame 21, a billet rack 22, and brushes 25. The cleaning frame 21 is rotatably connected to the bottom wall of the outer shell 1. A notch is provided at the front end of the cleaning frame 21, allowing aluminum billets to enter the interior of the cleaning frame 21. The cleaning frame 21 does not coincide with the central axis of the outer shell 1. The billet rack 22 is rotatably connected to the bottom wall of the cleaning frame 21. Decontamination assembly 2 also includes a lower pressure plate 23 and bolts 24. Guide grooves are provided on the upper ends of the left and right inner walls of the billet rack 22, and the lower pressure plate 23 is slidably connected between the two guide grooves. The upper right side of the billet rack 22 is threaded with bolts 24, and the lower end of bolts 24 is rotatably connected to the upper side of the lower pressure plate 23. The inner wall of the cleaning frame 21 is provided with evenly distributed brushes 25. Decontamination assembly 2 also includes a protective plate. 26 and 27, the upper end of the inner arc surface of the outer shell 1 is provided with a perforated plate 5, the top wall of the outer shell 1 is mounted with a mounting plate 3 by a mounting column, the outer arc surface of the mounting plate 3 and the inner arc surface of the perforated plate 5 are both provided with sliding grooves 6, a guard plate 26 is slidably connected between the two sliding grooves 6, the left end of the guard plate 26 is rotatably connected with a rotating shaft 27, the lower end of the rotating shaft 27 passes through the upper side wall of the cleaning frame 21 and is fixedly connected to the upper side of the blank rack 22, the decontamination component 2 also includes a gear 28 and an internal gear ring 29, the upper side of the perforated plate 5 is provided with an internal gear ring 29, the upper end of the rotating shaft 27 is provided with a gear 28, the gear 28 is meshed with the internal gear ring 29, the top wall of the outer shell 1 is rotatably connected with a main shaft 4, the lower end of the main shaft 4 passes through the middle of the mounting plate 3 and is fixedly connected to the upper side of the cleaning frame 21, the main shaft 4 The central axis of the cleaning frame 21 is not coincident. A motor 14 is installed on the upper side of the outer casing 1. The output shaft of the motor 14 is fixedly connected to the center of the upper end face of the main shaft 4. The input end of the motor 14 is electrically connected to the output end of the control switch group 15. Then, the material door 12 is opened, and the aluminum billet is placed on the billet rack 22. The bolt 24 is rotated. Since the bolt 24 is threadedly connected to the billet rack 22 and its lower end is rotatably connected to the lower pressure plate 23, the rotation of the bolt 24 will drive the lower pressure plate 23 to slide up and down in the guide groove, thereby pressing and fixing the billet on the billet rack 22 to prevent the billet from shaking during the cleaning process and to ensure the cleaning effect. Then, the material door 12 is closed, and the electric cylinder 13 is operated by the control switch group 15. The telescopic end of the electric cylinder 13 pushes the baffle 7 downward. As plate 7 moves downwards, it gradually blocks inlet and outlet 9. Then, the control switch group 15 activates motor 14. The output shaft of motor 14 drives main shaft 4 to rotate. Because main shaft 4 is fixedly connected to cleaning frame 21 and their central axes do not coincide, the rotation of main shaft 4 causes cleaning frame 21 to rotate eccentrically around an axis offset from its own center. This eccentric rotation generates centrifugal force, causing the cleaning fluid to flow irregularly within cleaning frame 21, enhancing the cleaning effect. Simultaneously, the rotation of cleaning frame 21 drives blank holder 22 to rotate. Since rotating shaft 27 is fixedly connected to blank holder 22, and the gear 28 at the upper end of rotating shaft 27 meshes with the internal gear ring 29 on the upper side of perforated plate 5, when cleaning frame 21 drives rotating shaft 27 to revolve...Gear 28 rotates under the action of internal gear ring 29, causing billet rack 22 to rotate around the center of cleaning frame 21 while also rotating itself. This allows the aluminum billet on billet rack 22 to come into full contact with the evenly distributed brushes 25 on the inner wall of cleaning frame 21. The brushes 25 scrub the surface of the billet, removing oil and dirt. Simultaneously, after the external circulation pump starts, it draws cleaning fluid from the storage tank and continuously delivers it into the device through inlet pipe 10. During the cleaning process, cleaning fluid continuously flows in from inlet pipe 10, ensuring that there is always sufficient cleaning fluid in cleaning frame 21 to clean the aluminum billet. Because the cleaning solution is continuously circulated, its concentration and cleaning ability remain relatively stable, preventing the cleaning effect from being affected by the solution gradually becoming dirty. During the cleaning process, the cleaning solution containing oil and impurities is discharged through the discharge pipe 11. This wastewater first enters the filtration device, which is equipped with multiple layers of filter screens or filter media to effectively filter out oil, metal debris, and other impurities from the cleaning solution. After filtration, the cleaning solution becomes relatively clean and flows back to the cleaning solution storage tank, where it mixes with the existing cleaning solution and continues to circulate, removing oil from the surface of the aluminum billet through cleaning.

[0016] The working principle of the billet degreasing device provided by this utility model is as follows: First, the inlet pipe 10 is connected to the external cleaning liquid storage tank and the circulation pump, and the outlet pipe 11 is connected to the external filter device and the cleaning liquid storage tank. Then, the control switch group 15 is operated to make the electric cylinder 13 operate. The extension end of the electric cylinder 13 pushes the baffle 7 upward. As the baffle 7 moves upward, it gradually moves away from the inlet and outlet 9. Then, the material door 12 is opened, and the aluminum billet is placed on the billet rack 22 through the notch at the front end of the cleaning frame 21. The bolt 24 is rotated. Since the bolt 24 is threadedly connected to the billet rack 22 and its lower end is rotatably connected to the lower pressure plate 23, the rotation of the bolt 24 will drive the lower pressure plate 23 to slide up and down in the guide groove, thereby pressing and fixing the billet. To prevent the billets from shaking during cleaning and ensure cleaning effectiveness, the material door 12 is closed immediately afterward. The electric cylinder 13 is then activated via the control switch assembly 15. The telescopic end of the electric cylinder 13 pushes the baffle 7 downward, gradually blocking the inlet and outlet 9 as it moves downward. Next, the control switch assembly 15 activates the motor 14, whose output shaft drives the main shaft 4 to rotate. Because the main shaft 4 is fixedly connected to the cleaning frame 21 and their central axes do not coincide, the rotation of the main shaft 4 causes the cleaning frame 21 to rotate eccentrically around an axis deviating from its own center. This eccentric rotation generates centrifugal force, causing the cleaning fluid to flow irregularly within the cleaning frame 21, thus enhancing the cleaning effect. In addition, the rotation of the cleaning frame 21 drives the blank holder 22 to rotate. Since the rotating shaft 27 is fixedly connected to the blank holder 22, and the gear 28 at the upper end of the rotating shaft 27 meshes with the internal gear ring 29 on the upper side of the perforated plate 5, when the cleaning frame 21 drives the rotating shaft 27 to revolve, the gear 28 will rotate under the action of the internal gear ring 29, thereby causing the blank holder 22 to rotate around the center of the cleaning frame 21 while also rotating itself. In this way, the aluminum blanks on the blank holder 22 can come into full contact with the brushes 25 evenly distributed on the inner wall of the cleaning frame 21. The brushes 25 brush the surface of the blanks to remove oil stains. At the same time, after the external circulation pump is started, the cleaning liquid in the storage tank is extracted and continuously transported to the loading tank through the liquid inlet pipe 10. Inside the cleaning chamber, during the cleaning process, the cleaning fluid continuously flows in from the inlet pipe 10, ensuring that there is always enough cleaning fluid in the cleaning frame 21 to clean the aluminum billet. Since the cleaning fluid is continuously circulated, the concentration and cleaning ability of the cleaning fluid can be kept relatively stable, avoiding the cleaning effect from being affected by the cleaning fluid gradually becoming dirty. During the cleaning process, the cleaning fluid containing oil and impurities is discharged from the device through the outlet pipe 11. This wastewater first enters the filtration device, which is equipped with multiple layers of filter screens or filter media, which can effectively filter out oil, metal debris and other impurities in the cleaning fluid. The cleaning fluid becomes relatively clean after filtration and then flows back to the cleaning fluid storage tank, mixes with the original cleaning fluid in the storage tank, and continues to participate in the circulation.

[0017] It is worth noting that the electric cylinder 13 disclosed in the above embodiments can be a DYTZ series, the motor 14 can be an RS-550 series DC motor, and the control switch group 15 is provided with control buttons that correspond one-to-one with the electric cylinder 13 and the motor 14 and are used to control their switching.
