Description

Technical Field

[0001] The present invention relates to the field of surface treatment of aluminum profiles, and particularly to an alkali sand treatment device for aluminum profiles. Background Art

[0002] During the production process of aluminum profiles, anodic oxidation treatment is required to form a dense aluminum oxide protective layer on the surface of the aluminum profiles to improve the corrosion resistance, hardness, wear resistance, and aesthetics of the aluminum materials; before anodic oxidation, the aluminum profiles need to be subjected to alkali sand treatment.

[0003] Alkali sand treatment requires soaking the aluminum profiles in a high-temperature strong alkali solution. During this process, pungent odors and hydrogen gas are generated. At the same time, small defects such as slight scratches, burrs, and abrasions on the surface of the aluminum profiles will be smoothed; after the alkali sand treatment for a fixed time, the aluminum profiles need to be transferred to a water tank for cleaning.

[0004] The above-related technologies have the following defects: During the transfer process of the aluminum profiles from the strong alkali solution to the clear water, the strong alkali solution adhering to the aluminum profiles will corrode the aluminum profiles, resulting in the situation that the aluminum profiles are over-corroded. Summary of the Invention

[0005] In order to solve the technical problem of reducing the amount of corrosion of aluminum profiles during the transfer process, the present invention provides an alkali sand treatment device for aluminum profiles.

[0006] An alkali sand treatment device for aluminum profiles provided by the present invention adopts the following technical solution:

[0007] An alkali sand treatment device for aluminum profiles includes an adjacent alkali water tank and a clear water tank; it also includes a support moving device; the support moving device includes a moving bracket, a vertical driving mechanism, and an upper cover body; the vertical driving mechanism is arranged on the moving bracket and is used to drive the upper cover body to vertically lift and lower; the upper cover body is a rectangular cover body with an opening facing downwards and is used to completely cover the alkali water tank and the clear water tank at the same time; a horizontal driving assembly and a hanging rack are arranged inside the upper cover body; the horizontal driving assembly is used to drive the hanging rack to horizontally move and its moving direction is parallel to the distribution direction of the alkali water tank and the clear water tank; the end face of the alkali water tank away from the clear water tank is vertically flush with the inner side wall of the corresponding side of the upper cover body; the width of the alkali water tank and the clear water tank perpendicular to the moving direction of the hanging rack is the same as the width of the inner cavity of the upper cover body perpendicular to the moving direction of the hanging rack; an aluminum profile placement rack is hung at the bottom of the hanging rack; the aluminum profile placement rack is used to horizontally place aluminum profiles; a plurality of vertical nozzles are arranged on the aluminum profile placement rack; the vertical nozzles are located directly above the aluminum profiles and are used to spray clear water onto the aluminum profiles; the vertical nozzles are connected to an external water supply device.

[0008] By adopting the above technical solution, during operation, after the aluminum profiles on the aluminum profile mounting rack are immersed in the alkali tank for alkali sand treatment, the vertical driving mechanism is used to drive the upper cover to rise vertically, so that the aluminum profiles are separated from the alkali tank. At this time, the vertical nozzle starts to spray water on the aluminum profiles. At the same time, the horizontal driving assembly drives the hanging rack to move towards the clear water tank. Then, the vertical driving mechanism is used to drive the upper cover to descend vertically, so that the aluminum profiles on the aluminum profile mounting rack are immersed in the clear water in the clear water tank. In this way, during the movement of the aluminum profiles, the strong alkali solution attached to the aluminum profiles is continuously diluted by spraying water, which greatly reduces the amount of corrosion of the aluminum profiles during the transfer process.

[0009] Optionally, it further includes an inclined sealing device; the inclined sealing device is located on the side of the alkali tank away from the clear water tank; a downwardly inclined slot is formed at the lower end of the end face of the upper cover close to the inclined sealing device, slanting from outside to inside; the inclined sealing device includes a sealing support frame, an inclined driving mechanism and an inclined sealing plate; the inclined sealing plate cooperates with the inclined slot and the two are parallel to each other; the inclined driving mechanism is arranged on the sealing support frame and is used to drive the inclined sealing plate to move along its inclined direction; when the inclined sealing plate is inserted into the inclined slot, the inclined sealing plate blocks the upper opening of the alkali tank and the lower end is located above the opening of the clear water tank.

[0010] By adopting the above technical solution, after the aluminum profiles are separated from the alkali tank and before the vertical nozzle sprays water; the inclined driving mechanism drives the inclined sealing plate to be inserted into the inclined slot, so that the inclined sealing plate blocks the upper opening of the alkali tank and the lower end is located above the opening of the clear water tank. In this way, the clear water sprayed by the subsequent vertical nozzle will not enter the alkali tank and finally flow into the clear water tank, thus avoiding accidentally changing the alkalinity in the alkali tank, which is beneficial to the alkali sand treatment of the aluminum profiles.

[0011] Optionally, a receiving groove is formed at the lower part of the inner side wall of the upper cover close to the alkali tank; the lower end of the receiving groove is communicated with the inclined slot; a scraping plate is arranged in the receiving groove; the lower end of the scraping plate is formed as an inclined surface and this inclined surface is on the same inclined surface as the upper side wall of the inclined slot; a scraping plate driving assembly is arranged on the upper cover; the scraping plate driving assembly is used for the scraping plate to move obliquely and the moving direction of the scraping plate is parallel to the inclined direction of the inclined slot.

[0012] By adopting the above technical solution, the scraping plate driving assembly drives the scraping plate to move together with the hanging rack. During this process, the bottom of the scraping plate scrapes the upper surface of the inclined sealing plate, so that the clear water on the inclined sealing plate enters the clear water tank more thoroughly, further reducing the possibility of clear water entering the alkali tank, thereby avoiding accidentally changing the alkalinity in the alkali tank, which is beneficial to the alkali sand treatment of the aluminum profiles.

[0013] Optionally, a plurality of horizontal nozzles are provided on the end face of the squeegee near the alkali water tank; the horizontal nozzles are used to spray clean water on the aluminum profile; the horizontal nozzles are connected to an external water supply device.

[0014] By adopting the above technical solution, the arrangement of the horizontal nozzles enables a larger amount of clean water to be sprayed on the aluminum profile, which is conducive to continuously diluting the strong alkali solution attached to the aluminum profile.

[0015] Optionally, both ends of the inclined slot perpendicular to its inclined direction extend to the side walls of the corresponding sides of the upper cover body.

[0016] By adopting the above technical solution, when the inclined sealing plate is inserted into the inclined slot, both ends of the inclined sealing plate are respectively inserted into the inner side walls on both sides of the upper cover body perpendicular to the moving direction of the hanging rack, which improves the sealing performance, further reduces the possibility of clean water entering the alkali water tank, thereby avoiding accidentally changing the alkalinity in the alkali water tank and being conducive to the alkali sand treatment of the aluminum profile.

[0017] Optionally, an exhaust fan is provided on the top of the upper cover body; during alkali sand treatment, the exhaust fan is located directly above the alkali water tank; the air inlet of the exhaust fan is communicated with the inside of the upper cover body, and the air outlet is connected to an external filtering device.

[0018] By adopting the above technical solution, the exhaust fan can discharge the pungent odor generated during the alkali sand process into the external filtering device for filtration, which greatly improves the working environment of the workshop and is conducive to the physical health of the staff.

[0019] Optionally, on a pair of side walls of the upper cover body perpendicular to the moving direction of the hanging rack, horizontally open telescopic slots are respectively formed; a blocking plate is horizontally telescopically arranged in the telescopic slot; a pair of telescopic driving components are provided on the upper cover body; the telescopic driving components correspond to the blocking plates one by one; the telescopic driving components are used to drive the blocking plates to horizontally telescope in the telescopic slot; when the upper cover body is at the lowest end, the lower end faces of a pair of mutually abutting blocking plates are flush with the upper end face of the alkali water tank, and the end face close to the alkali water tank is flush with the inner side wall of the alkali water tank close to the clean water tank.

[0020] By adopting the above technical solution, when a pair of blocking plates abut against each other, the gap between the upper cover body and the upper end face of the alkali water tank can be reduced, which is conducive to reducing the emission of pungent odor, thereby further improving the working environment of the workshop and being conducive to the physical health of the staff.

[0021] Optionally, a rectangular groove-shaped feeding and discharging opening with a horizontal opening is formed in the lower part of the side wall of the upper cover body close to the clean water tank; the lower end of the feeding and discharging opening is open; the feeding and discharging opening is used for feeding and discharging the aluminum profile.

[0022] By adopting the above technical solution, the aluminum profiles can be fed in and out through the feeding and discharging openings, facilitating the loading and unloading for alkali sand treatment, thereby improving the efficiency of alkali sand treatment.

[0023] Optionally, a gap is provided between the water tank and the side wall of the upper cover body close to the water tank, and this gap is used to accommodate the aluminum profile placement rack.

[0024] By adopting the above technical solution, during loading and unloading, the upper cover body can be lowered to the lowest position and the aluminum profile placement rack is located on the side of the water tank away from the alkali water tank, so that the aluminum profiles can be loaded and unloaded at a low position without the need to lift the aluminum profiles to a very high position, thus saving time and effort for the operator during loading and unloading.

[0025] Optionally, the upper side wall of the feeding and discharging opening is higher than the aluminum profile placement rack.

[0026] By adopting the above technical solution, the aluminum profile placement rack can be conveniently taken and placed through the feeding and discharging opening, and the replacement and maintenance of the aluminum profile placement rack are convenient.

[0027] In summary, the beneficial effects of the present invention are as follows:

[0028] 1. During the transfer of the aluminum profiles, by spraying water, the strong alkali solution attached to the aluminum profiles is continuously diluted, greatly reducing the corrosion amount of the aluminum profiles during the transfer process.

[0029] 2. The clear water sprayed by the vertical nozzles will not accidentally change the alkalinity in the alkali water tank, which is beneficial to the alkali sand treatment of the aluminum profiles. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The working principle of an aluminum profile alkali sand treatment device of the present application is as follows:

[0055] During alkali sand treatment, such as during work, as Figure 1As shown in the figure, at this time, the lower part of the aluminum profile placement rack 40 is immersed in the strong alkali solution in the alkali tank 10. In this way, the aluminum profiles on the aluminum profile placement rack 40 are immersed in the strong alkali solution in the alkali tank 10 for alkali sand treatment. After the treatment is completed, the vertical drive mechanism drives the upper cover 33 to rise. In this way, the aluminum profile placement rack 40 and the aluminum profiles thereon are moved away from the alkali tank 10 together. Then, the tilt drive motor 65 drives the tilt drive gear 64 to rotate, and through the gear-rack drive, the tilt sealing plate 63 is tilted and slid into the tilt slot 3301 along a pair of tilt sliding grooves 610. In this way, the tilt sealing plate 63 covers the upper opening of the alkali tank 10 and its lower end is located above the opening of the water tank 20; then the vertical nozzle 42 sprays clear water, and the clear water is sprayed on the aluminum profile to dilute the strong alkali solution attached thereto. Then, the horizontal drive assembly drives the hanging rack 35, the aluminum profile placement rack 40 and the aluminum profiles thereon to move together in the direction of the water tank 20. At the same time, the scraper drive assembly drives the scraper 37 to move, and the horizontal nozzle 38 on the scraper 37 sprays clear water on the aluminum profile. During this process, the bottom of the scraper 37 scrapes the upper end surface of the tilt sealing plate 63, so that the remaining clear water flows into the water tank 20 along the upper end surface of the tilt sealing plate 63; when the hanging rack 35, the aluminum profile placement rack 40 and the aluminum profiles thereon leave the upper side of the alkali tank 10, the scraper 37 and the tilt sealing plate 63 return to their original positions. Then, the vertical drive mechanism drives the upper cover 33 to descend so that the aluminum profiles are immersed in the clear water in the water tank 20 for cleaning. After the cleaning is completed, the vertical drive mechanism drives the upper cover 33 to rise. Then, the horizontal drive assembly drives the hanging rack 35, the aluminum profile placement rack 40 and the aluminum profiles thereon to move together towards the inlet and outlet. Then, the vertical drive mechanism drives the upper cover 33 to descend. In this way, the aluminum profile placement rack 40 and the aluminum profiles thereon are located on the side of the water tank 20 away from the alkali tank 10. At this time, the loading and unloading of the aluminum profiles can be carried out;

[0056] During the above process, the aluminum profiles are continuously sprayed with clear water when moving from the alkali tank 10 to the water tank 20. In this way, the strong alkali solution attached to the aluminum profiles is continuously diluted, thereby reducing the amount of corrosion of the aluminum profiles during this process.

[0057] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention should be covered within the protection scope of the present invention.
