Description

Technical Field

[0001] This utility model relates to the field of aluminum single-panel passivation treatment technology, and more specifically, to a chromium-free passivation treatment device for aluminum single-panels. Background Technology

[0002] Aluminum single-layer panels are building decoration materials that have undergone chromating and other treatments, followed by fluorocarbon spraying technology. The formation of a dense oxide protective layer on the surface of metals such as steel and aluminum prevents further reaction with the metal, a phenomenon known as passivation. They have excellent resistance to cold and heat, can withstand strong ultraviolet radiation, and can maintain their color and prevent powdering for a long time, resulting in a long service life.

[0003] A search revealed a prior art device for chromium-free passivation treatment of aluminum panels, patent publication number CN217230939U. The specification states that: the storage tank is hollow to facilitate the storage of the passivation solution; a heating box is installed on the fixed frame to quickly dry the aluminum panel below with the help of heating rods; the telescopic arms of four electric telescopic rods are connected to a U-shaped plate; the storage box is easily removed and replaced with the cooperation of a slider and a sliding groove; and a door is installed to seal the storage tank and the inside of the fixed frame, reducing the impact of the external environment on the interior.

[0004] However, in actual use, degreasing and washing are usually performed before passivation of aluminum panels to ensure a relatively clean surface. During degreasing, a cleaning agent is usually placed in a tank, and the aluminum panels are immersed in the tank. Aeration pipes are then used to accelerate the water flow, thereby achieving the purpose of cleaning the aluminum panels. However, after a period of use, grease will accumulate in the water. Once the grease adheres to the air outlet of the aeration pipe, it will affect the air output of the aeration pipe, reducing the cleaning efficiency and making the use less economical. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a chromium-free passivation treatment device for aluminum single panels, so as to solve the problem that in the prior art, after the grease inside the water body adheres to the air outlet of the aeration pipe, it will affect the air output of the aeration pipe, reduce the cleaning efficiency, and thus make the use less economical.

[0007] The mounting sleeve has two mounting slots inside. A compression plate is fixedly connected to the end of the locking block away from the slot. A pull rope is fixedly connected to the end of the compression plate away from the locking block. A pull ring is fixedly connected to the end of the pull rope away from the compression plate. An elastic element is sleeved on the outside of the pull rope.

[0008] The filter screen is fixedly connected to a sealing ring, and a limiting groove is formed inside the outer periphery of the sealing ring. A sealing groove is formed on the upper side of the inner side of the mounting sleeve, and a limiting ring is fixedly connected to the inner wall of the sealing groove.

[0009] The card block is slidably connected inside the mounting groove, the extrusion plate is slidably connected inside the mounting groove, and one side of the pull rope is slidably connected inside the mounting groove.

[0010] The aeration pipe has a groove on its upper outer side, the pull ring is slidably connected inside the groove, and the other side of the pull rope is slidably connected inside the groove.

[0011] One end of the elastic element is fixedly connected to the inner wall of the mounting groove, and the other end of the elastic element is fixedly connected to the extrusion plate.

[0012] The sealing ring slides against the inner wall of the mounting sleeve, the sealing ring fits against the inside of the sealing groove, and the limiting ring fits against the inside of the limiting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In the above solution, by installing the filter screen inside the mounting sleeve and snapping the mounting sleeve onto the aeration pipe, the filter screen can be easily replaced, resulting in high filter screen replacement efficiency.

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] Example 1: Please refer to Figures 1 to 5 This utility model provides a technical solution: a chromium-free passivation treatment device for aluminum single panels, including a tank 1. Two aeration pipes 2 are fixedly connected inside the tank 1. Two slots 3 are opened on the outside of the aeration pipes 2. A locking block 4 is locked inside the slots 3. An installation sleeve 5 is slidably connected to the outside of the locking block 4, so that the installation sleeve 5 can be limited. A filter screen 6 is slidably connected to the upper side inside the installation sleeve 5. The bottom end of the filter screen 6 is attached to the top end of the aeration pipe 2, so that the filter screen 6 is limited. The installation sleeve 5 is sleeved on the outside of the aeration pipe 2. The contact part between the installation sleeve 5 and the aeration pipe 2 is a protruding annular structure and is adapted to the aeration pipe 2, so that the installation stability of the installation sleeve 5 is high.

[0024] When the filter screen 6 needs to be replaced, the two locking blocks 4 are pulled to opposite sides, allowing the locking blocks 4 to disengage from the inside of the locking groove 3 and slide into the inside of the mounting sleeve 5. Then, the mounting sleeve 5 is pulled upwards, separating it from the aeration pipe 2. This removes the restriction of the mounting sleeve 6 on the filter screen 6, allowing the filter screen 6 to detach from the inside of the mounting sleeve 5. At this point, the filter screen 6 can be disassembled. Conversely, the filter screen 6 can be installed. This method ensures high filter screen 6 replacement efficiency without affecting the cleaning efficiency of the aluminum panel, resulting in high economic efficiency.

[0025] Example 2: Based on Example 1, to facilitate the pulling of the mounting sleeve 5, two mounting grooves 7 are provided inside the mounting sleeve 5. The locking block 4 is slidably connected inside the mounting groove 7, and the mounting groove 7 provides movement space for the locking block 4. A pressing plate 8 is fixedly connected to the end of the locking block 4 away from the locking groove 3. The pressing plate 8 is slidably connected inside the mounting groove 7, and the mounting groove 7 limits the pressing plate 8, preventing it from shifting during sliding. A pull rope 9 is fixedly connected to the end of the pressing plate 8 away from the locking block 4. One side of the pull rope 9 is slidably connected inside the mounting groove 7. A pull ring 10 is fixedly connected to one end of the extrusion plate 8. A groove 12 is provided on the upper outer side of the aeration pipe 2. The pull ring 10 is slidably connected inside the groove 12. The groove 12 limits the pull ring 10, allowing it to slide smoothly. The other side of the pull rope 9 is slidably connected inside the groove 12. The mounting groove 7 and the groove 12 limit the pull rope 9, allowing it to slide smoothly. An elastic element 11 is sleeved on the outside of the pull rope 9. One end of the elastic element 11 is fixedly connected to the inner wall of the mounting groove 7, and the other end of the elastic element 11 is fixedly connected to the extrusion plate 8.

[0026] When the mounting sleeve 5 needs to be pulled, the pull ring 10 is pulled upward, which causes one end of the pull rope 9 to move upward, and the other end of the pull rope 9 to pull the compression plate 8 to compress the elastic element 11 and deform it. This causes the compression plate 8 to pull the locking block 4 into the interior of the mounting groove 7. Conversely, by releasing the pull ring 10, the elastic element 11 can perform a reset movement, which causes the elastic element 11 to push the compression plate 8 to move inward, so that the compression plate 8 can push the locking block 4 to engage with the interior of the locking groove 3.

[0027] Example 3: Based on Example 2, in order to improve the stability of the aeration pipe 2, a sealing ring 13 is fixedly connected to the outside of the filter screen 6. The sealing ring 13 slides against the inner wall of the mounting sleeve 5, so that the sealing ring 13 can be squeezed and deformed. A limiting groove 14 is opened inside the outer periphery of the sealing ring 13. A sealing groove 15 is opened on the upper side of the inner side of the mounting sleeve 5. The sealing ring 13 fits into the inside of the sealing groove 15, thereby sealing the connection between the aeration pipe 2 and the mounting sleeve 5. A limiting ring 16 is fixedly connected to the inner wall of the sealing groove 15. The limiting ring 16 fits into the inside of the limiting groove 14, so that the connection between the aeration pipe 2 and the mounting sleeve 5 is better sealed.

[0028] When the filter screen 6 slides into the interior of the mounting sleeve 5, the sealing ring 13 is squeezed and deformed. When the top of the filter screen 6 is in contact with the upper side of the inner wall of the mounting sleeve 5, the sealing ring 13 can perform a reset movement, so that the sealing ring 13 can be in contact with the interior of the sealing groove 15, and the limiting ring 16 can be in contact with the interior of the limiting groove 14. This makes the connection between the aeration pipe 2 and the mounting sleeve 5 highly sealed, thus preventing air leakage and making the aeration stability high.

[0029] The working process of this utility model is as follows:

[0030] When the filter screen 6 needs to be installed, pulling the pull ring 10 upwards causes one end of the pull rope 9 to move upwards, and the other end of the pull rope 9 to pull the compression plate 8 to compress the elastic element 11, causing deformation. This causes the compression plate 8 to pull the locking block 4 into the installation groove 7, thereby sliding the filter screen 6 into the installation sleeve 5 and placing the installation sleeve 5 on the outside of the aeration pipe 2. When the upper and lower sides of the filter screen 6 are respectively in contact with the upper inner wall of the installation sleeve 5 and the top of the aeration pipe 2, the sealing ring 13 can perform a reset movement, allowing the sealing ring 13 to engage with the sealing groove. The internal parts of the 15 fit together, allowing the limiting ring 16 to fit together with the internal parts of the limiting groove 14. This ensures a high degree of sealing between the aeration pipe 2 and the mounting sleeve 5, preventing air leakage and improving aeration stability. By releasing the pull ring 10, the elastic element 11 can perform a reset movement, pushing the extrusion plate 8 inward. This allows the extrusion plate 8 to push the locking block 4 into the slot 3. Conversely, disassembly can be easily performed, resulting in high filter screen 6 replacement efficiency without affecting the cleaning efficiency of the aluminum panel, thus improving economic efficiency.
