Description

Technical Field

[0001] This utility model relates to the field of oxidation rinsing, specifically to an oxidation rinsing device for aluminum tube surfaces. Background Technology

[0002] The aluminum tube surface oxidation rinsing device is a special equipment for aluminum tube surface treatment. It forms a dense aluminum oxide film on the surface of the aluminum tube by oxidizing it to improve the corrosion resistance and hardness of the aluminum tube. The device uses a rinsing process to clean the chemical solution or other impurities remaining on the surface of the aluminum tube after oxidation treatment.

[0003] Chinese Patent No. CN221908719U discloses a countercurrent rinsing device for metal anodizing, including a U-shaped frame. A first hydraulic cylinder is fixedly installed on the side wall of the left vertical section of the U-shaped frame. A first opening is provided at the lower end of the left vertical section of the U-shaped frame. An impurity collection mechanism is provided at the lower end of the piston rod of the first hydraulic cylinder. The first hydraulic cylinder drives the collection box to be placed in the cleaning tank, so that the suspended impurities flow into the collection box in conjunction with the arc-shaped guide plate, which facilitates timely cleaning of the suspended impurities in the cleaning tank. The first hydraulic cylinder drives the collection box to be positioned directly opposite the first opening, which facilitates the cleaning of the suspended impurities in the collection box.

[0004] When collecting debris that has fallen off the material surface, the existing rinsing device requires the debris to actively flow into the collection box with the water flow. This causes the debris to easily flow elsewhere, affecting the overall water quality inside the device. Consequently, the rinsing device needs to frequently replace the internal rinsing liquid, increasing rinsing costs. Utility Model Content

[0005] The purpose of this invention is to provide an aluminum tube surface oxidation rinsing device. The limiting frame slides along the second mounting column, which allows the liquid discharged from the extension tube to fully contact the aluminum tube. The debris falling off the aluminum tube surface can be completely restricted and collected by the first and second filters, avoiding the inefficient collection of debris and preventing the water quality from deteriorating rapidly. This solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum tube surface oxidation rinsing device, comprising an outer shell with a placement frame inside, a limiting frame outside the placement frame, a second handle at the upper end of the placement frame, and first mounting posts slidably penetrating inside the second handle welded to both the front and rear ends of the limiting frame. An extension tube is provided on one side inside the outer shell, and a first filter screen is provided on the other side of the limiting frame. A second filter screen is provided at the lower end between the first filter screen and the limiting frame. The reserved second handle facilitates the installation and disassembly of the placement frame, making it easy to remove the aluminum tube. The placement frame, by moving the aluminum tube into the limiting frame, allows all debris to be restricted and collected by the first and second filters.

[0007] Preferably, a first collection frame is provided on the outside of the first filter screen, and a second collection frame is provided at the lower end of the first collection frame. The second collection frame is fixedly connected to the four corners of the second filter screen by bolts. The reserved first and second collection frames can facilitate the installation of the first and second filters screens.

[0008] Preferably, the limiting frame has a through hole on the side facing the extension tube, and the through hole is connected to the external slot of the extension tube. The through hole and the outside of the extension tube can restrict the discharge of liquid at the position of the extension tube, so that the liquid discharged at the position of the extension tube can be fully received and the liquid can fully contact the copper tube.

[0009] Preferably, both sides of the first collection frame are recessed with movable grooves, and the limiting frame is provided with a first handle facing the movable groove. The first handle is rotatably connected to the limiting frame. The reserved movable grooves facilitate the installation and rotation of the first handle, and the rotation of the first handle can fix the first collection frame.

[0010] Preferably, the mesh size of the second filter screen is smaller than that of the first filter screen. The difference in mesh size can force the liquid to flow actively toward the second filter screen.

[0011] Preferably, the extension tube has a second mounting post extending towards the limiting frame at each of its four corners, and the second mounting post is embedded in the limiting frame and slidably connected to the inside of the limiting frame. A limiting piece is provided at the upper end of the extension tube, and the lower end of the limiting piece is connected to the upper end slot of the limiting frame and the outer shell. The limiting piece can be locked onto the outside of the limiting frame and the outer shell to fix the horizontally sliding limiting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] The limiting frame outside the placement frame of this utility model can slide along the outside of the second mounting post. The sliding can be directed towards the extension tube, allowing the returning liquid to fully contact the aluminum tube inside the placement frame, which can improve rinsing efficiency. Secondly, after the limiting frame wraps around the placement frame, it can guide and collect the rinsed liquid, causing the debris falling off the surface of the aluminum tube to flow towards the first collection frame. The liquid passing through can be filtered by the first and second filters, allowing the debris to be collected inside the first and second collection frames. Finally, the second filter, which is bolted on, has a smaller mesh size than the first filter, causing the flowing liquid to be more biased towards the inside of the second collection frame. Correspondingly, the debris restricted by the first filter will also be carried towards the inside of the second collection frame along the liquid flow trajectory, ultimately allowing the debris to be collected inside the second collection frame. The second filter can be directly removed during the final cleaning to dispose of and dispose of the debris. The debris falling off the surface of the aluminum tube can be collected efficiently and comprehensively. After the debris falls off, it is directly filtered and collected, avoiding affecting the water quality inside the outer shell. Attached Figure Description

[0021] The present invention will be further described below with reference to specific embodiments.

[0022] like Figure 1 As shown, an aluminum tube surface oxidation rinsing device according to this embodiment includes a housing 1, a placement frame 13 is provided inside the housing 1, and a limiting frame 8 is provided outside the placement frame 13. The aluminum tube to be rinsed is placed inside the placement frame 13, and the debris falling off the surface of the aluminum tube is collected by the limiting frame 8.

[0023] Furthermore, a second handle 12 is provided at the upper end of the placement frame 13, and a first mounting post 18 is vertically provided at both the front and rear ends of the restriction frame 8. The lower end of the first mounting post 18 is welded and fixed to the front end of the restriction frame 8. The outer side of the first mounting post 18 slides through the interior of the second handle 12. The placement frame 13 can be moved longitudinally and horizontally by the guidance and support of the first mounting post 18, which facilitates the insertion and removal of aluminum tubes from the side of the placement frame 13.

[0024] It is worth mentioning that, in order to collect the debris on the surface of the aluminum tube inside the placement frame 13, an extension tube 5 is provided on one side inside the outer shell 1. The extension tube 5 is the entry point for the rinsing liquid. The backflowing liquid flows into the interior of the outer shell 1 through the extension tube 5. A through hole is provided on the side of the outer side of the limiting frame 8 facing the extension tube 5, and the through hole is connected to the external slot of the extension tube 5. During the lateral movement of the limiting frame 8, the liquid discharged from the extension tube 5 can fully contact the aluminum tube.

[0025] A first filter screen 10 is provided on the other side of the limiting frame 8, and a second filter screen 15 is provided at the lower end between the first filter screen 10 and the limiting frame 8. After the liquid discharged from the extension tube 5 comes into contact with and carries the debris, the debris can be directly filtered and limited by the first filter screen 10 and the second filter screen 15. A first collection frame 7 is provided outside the first filter screen 10, such as... Figure 2 and Figure 3 As shown, a second collection frame 16 is provided at the lower end of the first collection frame 7, and the second collection frame 16 is fixedly connected to the four corners of the second filter screen 15 by bolts. The first collection frame 7 and the second collection frame 16 can respectively drive the first filter screen 10 and the second filter screen 15 to collect and restrict debris.

[0026] In this embodiment, both sides of the first collection frame 7 are recessed with movable grooves 17, and the limiting frame 8 is provided with a first handle 9 facing the movable groove 17. After the first handle 9 passes through the movable groove 17, it can be rotated to fit the first collection frame 7. The first handle 9 is rotatably connected to the limiting frame 8. The rotation of the first handle 9 can prevent the first collection frame 7 from fitting, which can facilitate the disassembly of the first collection frame 7 and prevent the first collection frame 7 and the lower second collection frame 16 from falling off. It can also facilitate the installation and disassembly of the first filter screen 10 and the second filter screen 15, which can be used for the processing and collection of debris.

[0027] To ensure uniform collection of debris, the second collection frame 16 and the first collection frame 7 are integrated into a single structure, such as... Figure 4 As shown, the mesh count of the second filter 15 is smaller than that of the first filter 10. The difference in mesh count makes it easier for the liquid to flow into the second collection frame 16. This easier flow into the second collection frame 16 also causes debris that has passed through the first filter 10 to flow into the second collection frame 16, allowing the debris to be collected uniformly inside the second collection frame 16. This allows the debris to be discharged directly after the second filter 15 is removed. Debris that remains on the surface of the first filter 10 can also be tilted and discharged from the second collection frame 16.

[0028] To facilitate the installation of the limiting frame 8, the four corners of the extension tube 5 are provided with second mounting posts 19 extending toward the limiting frame 8. The second mounting posts 19 are embedded in the limiting frame 8 and slidably connected to the inside of the limiting frame 8. The limiting frame 8 can be directly installed to the outside of the second mounting posts 19 by sliding. The sliding also facilitates the installation process, and the extension tube 5 can be embedded into the through hole inside the limiting frame 8, which is convenient for the assembly of the limiting frame 8.

[0029] Furthermore, in order to fix the outer shell 1 and the placement frame 13, a limiting piece 14 is provided at the upper end of the extension tube 5, and the lower end of the limiting piece 14 is connected to the upper end slot of the limiting frame 8 and the outer shell 1. After the limiting frame 8 is installed horizontally, the limiting piece 14 can be moved and directly locked onto the outside of the limiting frame 8 and the outer shell 1.

[0030] It is worth mentioning that a base 20 is provided on the other side of the outer casing 1, such as... Figure 5 and Figure 6 As shown, the base 20 has a third mounting post 21 on both sides of the upper end, and the third mounting post 21 is welded and fixed to the base 20. The third mounting post 21 is connected to the retaining plate 14 through the slot. After the retaining plate 14 slides to the outside of the outer shell 1 and the placement frame 13, it can be restricted by the third mounting post 21.

[0031] The upper ends of the third mounting post 21 and the first mounting post 18 are both provided with nuts. After the placement frame 13 slides to the outside of the first mounting post 18 and the limiting piece 14 slides to the outside of the third mounting post 21, the nuts can be rotated to fix the frame.

[0032] In order to enable the recycling of rinsing liquid, a pump 2 is installed on the other side of the outer casing 1, and an electronic three-way valve 3 is installed on the other side of the pump 2. The electronic three-way valve 3 is sealed to the extension pipe 5 through the return pipe 4. Adjusting the electronic three-way valve 3 can facilitate the pump 2 to draw and the circulation of liquid, and also facilitate the discharge of rinsing liquid after the electronic three-way valve 3 is adjusted.

[0033] In this embodiment, the pump 2 is sealed to the other side of the lower end of the housing 1, which facilitates the complete discharge of liquid.

[0034] To improve the connection between the first collection frame 7 and the limiting frame 8, and to facilitate the stable flow of debris into the interior of the first collection frame 7, a rubber ring 6 is provided around the first collection frame 7 and the limiting frame 8, and the rubber ring 6 is fixed to the first collection frame 7 with glue. When installing the first collection frame 7, the rubber ring 6 can fill the gap between the first collection frame 7 and the limiting frame 8.

[0035] Working principle: The device is used to clean the oxide layer on the surface of the aluminum tube. The aluminum tube is placed inside the placement frame 13. The second handle 12 drives the lower end of the aluminum tube and the placement frame 13 to slide to the outside of the first mounting post 18. The limiting frame 8 drives the upper end of the placement frame 13 to slide along the second mounting post 19 toward the extension tube 5. The second filter screen 15 is fixed to the lower end of the second collection frame 16 by bolts passing through it. The first collection frame 7 and the second collection frame 16 slide to the outside of the first handle 9 at the four corners of the front end of the limiting frame 8. The first handle 9 rotates and locks into the outer wall of the first collection frame 7 within the movable groove 17, fixing the first filter screen 10 and the second filter screen 15. The limiting plate 14 slides longitudinally between the limiting frame 8 and the outer shell 1, and simultaneously locks into the first mounting post 18. The external rotating nuts of the third mounting post 21 and the first mounting post 18 achieve final fixation. The rinsing liquid is poured into the housing 1, and the pump 2 is started to draw out the liquid. After being guided by the electronic three-way valve 3, the liquid flows back to the placement frame 13 along the return pipe 4. The returning liquid fully contacts the aluminum tube, and the debris will fall off with the liquid flow. Some of the debris will come into contact with and be restricted by the first filter screen 10, while the other part of the debris enters the second collection frame 16 and is restricted by the second filter screen 15. The mesh size of the first filter screen 10 is larger than that of the second filter screen 15, which allows the liquid and debris to actively flow towards the inside of the second collection frame 16, so that the debris can be collected inside the second collection frame 16 for easy subsequent cleaning and processing.
