Description

Technical Field

[0001] This utility model relates to the field of anodizing tank technology, and specifically discloses an anodizing tank structure. Background Technology

[0002] To control the temperature of the anodizing bath within a specified range, some existing technologies install heat exchange tubes inside the anodizing bath. By introducing a heat exchange medium into these tubes, a heat exchange reaction occurs between the tubes and the bath solution, thus controlling the bath temperature. However, prolonged immersion in the bath solution causes scale (Al(OH)3 deposits) to form on the surface of the heat exchange tubes, severely impacting heat exchange efficiency. Therefore, the production process requires periodic shutdowns to clean the scale layer on the heat exchange tubes. This cleaning process is time-consuming and labor-intensive, significantly affecting production schedules. Utility Model Content

[0003] The purpose of this invention is to solve the above problems and provide an anodizing tank structure that can delay the scaling on the surface of heat exchange tubes, reduce the number of times the machine needs to be shut down to clean the scale, and improve production efficiency.

[0004] The objective of this utility model is achieved through the following technical solution: an anodizing tank structure, comprising a tank body; a heat exchange tube and an air jet mechanism located above the heat exchange tube are arranged inside the tank body, the heat exchange tube being distributed in a zigzag manner within the tank body; the air jet mechanism includes a gas distribution component and an air jet assembly connected to the gas distribution component for injecting gas onto the surface of the heat exchange tube from both the upper and lower sides.

[0005] The jet assembly includes two branch gas pipes distributed on both sides of the straight section of the heat exchange tube, and nozzles evenly arranged on the two branch gas pipes; the nozzle on one branch gas pipe injects gas from the upper part of the straight section of the heat exchange tube to the straight section of the heat exchange tube, and the nozzle on the other branch gas pipe injects gas from the lower part of the straight section of the heat exchange tube to the straight section of the heat exchange tube.

[0006] The nozzle is tilted so as to inject gas into the straight section of the heat exchange tube at a 45-degree angle.

[0007] The gas distribution assembly includes an intake pipe and a gas distribution pipe connected to the intake pipe; the branch gas pipe is connected to the gas distribution pipe.

[0022] Example

[0023] like Figure 1 As shown, this embodiment discloses an anodizing tank structure, which includes a tank body 10. The tank body 10 contains heat exchange tubes 20 and an air jet mechanism 30 located above the heat exchange tubes 20. Specifically, the heat exchange tubes 20 are arranged in a zigzag pattern at the bottom of the tank body 10, with both ends extending upwards along the sidewalls of the tank body 10 and crossing over the sidewalls. Both ends of the heat exchange tubes 20 are connected to an external temperature control system. The temperature control system heats or cools the heat exchange medium before supplying it into the heat exchange tubes 20. After heat exchange, the heat exchange medium in the heat exchange tubes 20 flows back to the temperature control system. Specifically, a sensor for monitoring the tank liquid temperature is also installed inside the tank body 10; this part is an existing design and will not be described in detail.

[0024] The jetting mechanism 30 can be fixed inside the tank 10 by a bracket (not shown in the figure), such as... Figure 2 , 3As shown, the jet mechanism 30 includes a gas distribution assembly and a jet assembly connected to the gas distribution assembly for injecting gas from the upper and lower sides onto the surface of the heat exchange tube 20.

[0025] In the setup, the number of jetting components matches the number of straight sections of the heat exchange tube 20. Each jetting component includes two branch gas pipes 33 distributed on both sides of the straight section of the heat exchange tube 20, and nozzles 35 evenly distributed on the two branch gas pipes 33. One branch gas pipe's nozzle 35 injects gas from above the straight section of the heat exchange tube 20, while the other branch gas pipe's nozzle 35 injects gas from below the straight section of the heat exchange tube 20. Specifically, the nozzles 35 can be connected to the branch gas pipes 33 via auxiliary pipes, allowing the nozzles 35 on both branch gas pipes 33 to inject gas from both above and below the straight section of the heat exchange tube 20. Figure 2 As shown.

[0026] Nozzles 35 can be evenly spaced on the branch gas pipes 33. The spacing can be set according to actual conditions, such as 10 cm. The goal is to ensure the jetting range covers the straight sections of the heat exchange tubes 20 as much as possible. Although the curved sections of the heat exchange tubes 20 may not be sprayed with gas, the straight sections are the main points of contact between the tubes and the liquid in the tank. Delaying scaling on the straight sections of the heat exchange tubes 20 can significantly improve their heat exchange efficiency and reduce the frequency of downtime for cleaning. Scaling on the curved sections of the heat exchange tubes can be cleaned during equipment maintenance.

[0027] The nozzle 35 is inclined and sprays gas into the straight section of the heat exchange tube 20 at an inclined angle of 45 degrees, thereby increasing the gas spray range.

[0028] like Figure 2 , 3As shown, the gas distribution assembly includes an intake pipe 32 and a distribution pipe 31 connected to the intake pipe 32, with branch pipes 33 connected to the distribution pipe 31. The intake pipe 32 is connected to an external gas supply system, which supplies gas to the intake pipe 32. The gas is then distributed by the distribution pipe 31 to each branch pipe 33 and finally ejected by nozzles 35. In actual use, the gas pressure distributed to each branch pipe 33 and the gas pressure ejected by the nozzles 35 on the same branch pipe 33 may be different. To make the gas pressure as uniform as possible, the diameter of the distribution pipe 31 can be set to gradually decrease from one end near the intake pipe 32 to the other. If the intake pipe 32 is connected to the middle of the distribution pipe 31, the diameter of the distribution pipe 31 can be set to gradually decrease from the middle to both ends; similarly, the diameter of the branch pipes 33 can be set to gradually decrease from one end near the distribution pipe 31 to the other. Although it is impossible to make the air pressure ejected from all nozzles 35 completely uniform, as long as the air pressure ejected from nozzles 35 is sufficient to agitate the liquid near the heat exchange tube 20, it can still delay scaling on the heat exchange tube 20. In practice, the air pressure ejected from nozzles 35 should not be too high to avoid causing the liquid in the tank to surge and churn, which would affect the normal oxidation of the workpiece. The gas only needs to be brushed onto the surface of the heat exchange tube.

[0029] In specific settings, nitrogen is used as the sprayed gas. Nitrogen is an inert gas and will not react with the bath liquid. In addition, nozzle 35 is made of titanium alloy, and all pipes immersed in the bath liquid are made of titanium alloy, so they are not easily corroded by the bath liquid. Nozzle 35 is a one-way nozzle, so the bath liquid cannot enter the branch gas pipe 35 from nozzle 35.

[0030] During anodizing, the gas supply equipment can be activated to spray air after each batch of workpieces is oxidized. Each spraying time only needs to be a few seconds, which can prevent scale buildup on the heat exchange tubes. The short spraying time will not affect the normal oxidation process of the workpieces. It should be noted that because the spraying interval is not long, the nozzle 35 is not easily scaled and clogged under nitrogen flushing. In addition, the cathode assembly, stirring assembly, etc. in the tank 10 can be installed above the spraying assembly, as long as they avoid the spraying assembly.

[0031] In addition, the anodizing tank structure of this embodiment may also include an ultrasonic defoamer. The vibrator of the ultrasonic defoamer is disposed on the inner wall of the tank body 10 and above the tank liquid to prevent it from being corroded by the tank liquid. After the heat exchange tube 20 is flushed with gas, a small number of bubbles may be present in the tank liquid. The ultrasonic defoamer can eliminate the bubbles in the tank liquid to prevent them from affecting the oxidation effect of the workpiece.

[0032] In this embodiment, nitrogen gas is sprayed onto the heat exchange tube from both the top and bottom sides using a jetting mechanism. The nitrogen gas washes over the surface of the heat exchange tube, delaying the formation of scale on the surface, reducing the number of downtimes for scale cleaning, and improving production efficiency.

[0033] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.

[0034] Furthermore, the specific embodiments described above are exemplary.

Those skilled in the art should understand that this utility model specification and its drawings are illustrative and not intended to limit the scope of the claims.
