Description

Technical Field

[0001] This utility model belongs to the field of metal surface treatment technology and relates to a passivation pool. Background Technology

[0002] In the field of metal processing and manufacturing, passivation treatment is often required to improve the corrosion resistance and aesthetics of metallic materials. Passivation forms a protective film on the metal surface through a chemical reaction to prevent further oxidation or environmental corrosion. Passivation tanks, as key equipment for this process, are widely used in the surface treatment of materials such as stainless steel, aluminum, and their alloys.

[0003] Traditional passivation baths consist of a large-capacity container filled with specific chemical reagents (such as acidic solutions). The workpiece must be completely immersed in the passivation solution for a period of time to ensure a uniform passivation film forms on its surface. However, in practice, how to efficiently and safely place and remove workpieces from the passivation bath has become a pressing problem.

[0004] For small-scale production or laboratory environments, due to limitations in funding and technology, workpieces are often manually placed directly into the passivation bath. While this method is simple and intuitive, it is extremely inefficient and poses safety hazards. Frequent contact with chemicals is not only time-consuming and labor-intensive but may also expose operators to health risks.

[0005] To address these issues, some manufacturers have introduced suspended basket systems. In this system, the workpiece is placed in an open basket and then smoothly lifted into and out of the passivation tank using a crane or manual winch. This reduces the risk of direct human contact with chemicals and improves operational standardization. However, existing suspended basket systems still have shortcomings: the operation process is relatively cumbersome, the system flexibility is poor, and the operating speed is slow, resulting in overall low work efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a passivation pool that uses four-wheel drive to achieve efficient and automated passivation treatment of workpieces, meeting the needs of modern industry for efficient and safe operation.

[0007] To solve the above-mentioned technical problems, this utility model provides a passivation tank, including a tank body. The tank body is divided into a passivation chamber and a cleaning chamber distributed along its length by a vertical partition. A lifting platform is provided at both ends of the tank body. Slide rails extending to the lifting platforms at both ends are provided on both sides of the upper end of the tank body along its length. A passivation hanging bracket is provided above the tank body. Two support arms distributed in a figure-eight shape are rotatably connected to one side of each slide rail of the passivation hanging bracket. A mounting plate is provided at the lower end of each support arm. A roller that rolls on the corresponding slide rail is rotatably connected to the inner side of each mounting plate. A drive motor for driving the corresponding roller to rotate is installed on the outer side of each mounting plate.

[0008] Vertical baffles parallel to the slide rails are provided on both sides of the pool body and the cleaning chamber. Each vertical baffle is located inside the corresponding slide rail. A horizontal baffle is provided at the upper end of each vertical baffle. A water spray pipe is provided on the lower side of each horizontal baffle along its length. Multiple cleaning nozzles distributed along its length are connected to each water spray pipe. Each cleaning nozzle is inclined inward and downward. A tap water connection pipe is connected to the end of each water spray pipe away from the passivation chamber.

[0009] By adopting the above technical solution, the workpiece to be passivated is first placed into the basket, and the basket is placed on the lifting platform. The drive motor drives the rollers to move in the same direction, moving the passivation support frame above the lifting platform. After connecting the basket and the passivation support frame, the drive motor drives the rollers to move in the opposite direction above the passivation chamber. Then, the two rollers on the same side opposite to each other move in opposite directions, causing the support arm to open outward in a V-shape, allowing the passivation support frame to lower the basket. The basket is completely immersed in the passivation liquid for passivation. After passivation is completed, the support arm rotates inward, causing the passivation support frame to lift the basket from the passivation liquid. Then, the drive motor drives the passivation support frame to move the basket above the cleaning chamber. The cleaning nozzle sprays high-pressure water to rinse the workpiece under high pressure. The splashed water droplets are blocked by the vertical and horizontal baffles and fall into the cleaning chamber. Finally, after cleaning is completed, the basket is moved to the lifting platform at the rear end and unloaded, completing the passivation operation on one side.

[0010] The present invention is further configured such that the passivated hanging bracket is provided with multiple vertical pull bars downward, and each vertical pull bar is provided with a hook at its lower end. The vertical pull bars and the hooks are all made of highly corrosion-resistant materials.

[0011] The present invention is further configured such that the height of the horizontal baffle is lower than the maximum height that the passivated hanging bracket can rise to, and the vertical tie rod is allowed to pass through the indirect space between the two horizontal baffles.

[0012] The present invention is further configured such that both the vertical tie bar and the hook are made of highly corrosion-resistant stainless steel.

[0013] The present invention is further configured such that a first drain pipe communicating with the passivation chamber is provided outward at the lower part of the side wall of the pool body, and the first drain pipe is detachably connected to a first sealing plug.

[0014] The present invention is further provided that a second drain pipe communicating with the cleaning chamber is provided on the lower part of the side wall of the pool body, and the second drain pipe is detachably connected to a second sealing plug.

[0015] The present invention is further configured such that a solenoid valve is provided at the end of each water spray pipe away from the passivation chamber.

[0016] The present invention is further configured such that the pool body is made of polypropylene material.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] Firstly, this utility model adopts a brand-new passivation lifting bracket with four support bars distributed in a figure-eight shape for lifting and moving the workpiece. Each roller is driven by an independent drive motor, so that when the rollers rotate in the same direction, the passivation lifting bracket can move horizontally. When two rollers on the same side rotate in opposite directions, the two support arms open outward or retract inward, so as to raise or lower the passivation lifting bracket. The operation is simple and flexible, and it can put the workpiece into the passivation liquid for passivation treatment more efficiently, meeting the needs of modern industry for efficient and safe operation.

[0019] Secondly, after the workpiece is passivated, the cleaning nozzle above the cleaning chamber can quickly rinse away the residual passivation liquid on the workpiece surface, which can further improve the overall work efficiency. Attached Figure Description

[0025] Example, refer to Figure 1-3 A passivation tank includes a tank body 1 made of polypropylene. The tank body 1 is divided into a passivation chamber 3 and a cleaning chamber 4 along its length by a vertical partition 2. A first drain pipe 5, connected to the passivation chamber 3, is provided outward from the lower part of the side wall of the tank body 1. The first drain pipe is detachably connected to a first sealing plug 6. A second drain pipe 7, connected to the cleaning chamber 4, is provided outward from the lower part of the side wall of the tank body 1. The second drain pipe is detachably connected to a second sealing plug 8. The discharged liquid cannot be directly discharged and must be rendered harmless before discharge. A lifting platform 9 is provided at both ends of the tank body 1, and a slide rail 10 extending to the lifting platforms 9 is provided on both sides of the upper end of the tank body 1 along its length.

[0026] A passivated hanging bracket 11 is installed above the pool body 1. Two vertical tie bars 12 are installed downwards from the passivated hanging bracket 11. Each vertical tie bar 12 has a hook 13 at its lower end, connecting the basket to the frame. Both the vertical tie bars 12 and the hooks 13 are made of highly corrosion-resistant stainless steel. Two support arms 14 arranged in a V-shape are rotatably connected to one side of each slide rail 10 from the passivated hanging bracket 11. Each support arm 14 has a mounting plate 15 at its lower end. A roller 16 that rolls on the corresponding slide rail 10 is rotatably connected to the inner side of each mounting plate 15. A drive motor 17 is installed on the outer side of each mounting plate 15 to drive the corresponding roller 16. The drive motor 17 independently drives each roller 16, enabling flexible raising, lowering, and movement.

[0027] On both sides of the cleaning chamber 4, a vertical baffle plate 18 parallel to the slide rail 10 is installed upwards. Each vertical baffle plate 18 is located inside the corresponding slide rail 10. A horizontal baffle plate 19 is installed inwards at the upper end of each vertical baffle plate 18. The height of the horizontal baffle plate 19 is lower than the maximum height that the passivation hanger 11 can rise. A vertical tie rod 12 can pass through the gap between the two horizontal baffle plates 19. A water spray pipe 20 is installed on the lower side of each horizontal baffle plate 19 along its length. Multiple cleaning nozzles 21 distributed along its length are connected to each water spray pipe 20. The cleaning nozzles 21 are used to perform high-pressure rinsing on the workpiece to remove the passivation liquid remaining on the surface. Each cleaning nozzle 21 is inclined inwards and downwards. A tap water connection pipe 22 is connected to the end of each water spray pipe 20 away from the passivation chamber 3. A solenoid valve 23 is installed at the end of each water spray pipe 20 away from the passivation chamber 3.

[0028] Working principle: First, the workpiece to be passivated is placed into the basket, and the basket is placed on the lifting platform 9. The drive motor 17 drives the rollers 16 to move in the same direction, moving the passivation lifting bracket 11 above the lifting platform 9. After connecting the basket to the hook 13 on the passivation lifting bracket 11, the drive motor drives the rollers 16 to move in the opposite direction above the passivation chamber 3. Then, it drives the two opposite rollers 16 on the same side to move in opposite directions, causing the support arm 14 to open outward in a V-shape, allowing the passivation lifting bracket 11 to lower the basket. The basket is fully immersed in the passivation solution for passivation. After passivation, the support arm 14 rotates inward, causing the passivation lifting bracket 11 to lift the basket from the passivation solution. Then, the drive motor 17 drives the passivation lifting bracket 11 to move the basket above the cleaning chamber 4. The cleaning nozzle 21 sprays high-pressure water to rinse the workpiece under high pressure. The splashed water droplets are blocked by the vertical baffle 18 and the horizontal baffle 19 and fall into the cleaning chamber 4. After cleaning is completed, the basket is moved to the lifting platform 9 at the rear end and unloaded, completing the passivation operation on one side.

[0029] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.
