Description

Technical Field

[0001] The invention relates to the technical field of gas processing, in particular to a gas collecting device for oxidation of aluminum parts. Background Art

[0002] Aluminum oxidation usually refers to the aluminum oxidation process (such as anodizing or chemical oxidation) that generates a dense oxide film on the surface of aluminum parts through electrochemical or chemical reactions to improve its corrosion resistance, decorative properties or mechanical strength. During the oxidation process, gases such as oxygen and hydrogen are generated, and even corrosive acid mist or alkaline gas is released, depending on the specific process and the solution used. If these gases are not collected in time, they will cause harm to the environment and the health of operators, and will also damage equipment or increase potential safety hazards in production (such as the flammability of hydrogen).

[0003] In the prior art, the gas generated by the oxidation process of aluminum parts is often accompanied by a high temperature during the collection process. This high-temperature gas will have an adverse effect on the overall structure and performance of the gas collection device if it is not effectively cooled. Since the oxidation reaction process is usually carried out under high temperature or active environment, the generated gas will not only contain corrosive components (such as acid mist or alkaline gas), but also have significant thermal energy, which will cause continuous high temperature loads on the pipes, capture hoods and processing equipment (such as filters or adsorption towers) in the collection device.

When the disc 23 rotates, it will drive the slide bar 24 to perform a circular motion. When the slide bar 24 performs a circular motion, it will drive the slider 40 to translate. When the slider 40 translates, it will drive the movable plate 26 to translate at the same time through the connecting frame 25. When the movable plate 26 moves, it will drive multiple brushes 27 to clean the surface of the filter plate 19, and then under the action of the filter plate 19, the dust in the air can be filtered.

[0045] When the fan 18 draws the external air, the semiconductor refrigeration plate 13 will work.

At the same time, the heat dissipation fins 14 can dissipate heat on the other side of the semiconductor refrigeration plate 13, thereby making the semiconductor refrigeration plate 13 cool more effectively.
