[0002] Due to the particularity of their use environment, aviation, aerospace, and military parts require oxidation treatment when using aluminum alloy parts; aluminum alloys are widely used due to their high mechanical strength, easy processing, excellent thermal and electrical conductivity, and non-magnetic properties.

[0003] Aluminum alloy profiles (without surface treatment) have a simple appearance and are easily corroded in a humid atmosphere, so it is difficult to meet the requirements of high decorativeness and strong weather resistance. In order to improve the decorative effect, enhance corrosion resistance and extend the service life, aluminum profiles generally need to be surface treated. Anodizing is a commonly used aluminum alloy surface treatment process today, which generates a very thin oxide film on the surface of aluminum alloy workpieces, thereby playing a role in protection, decoration, insulation, etc.

[0041] A method for collecting and recovering waste gas for an aircraft parts oxidation production line, using the above-mentioned waste gas collection and recovery device for an aircraft parts oxidation production line, comprises the following steps:

[0042] Step 1: During the treatment, the exhaust gas is discharged into the treatment chamber 4 through the connecting pipe 2, and further enters the treatment chamber 501 through the air port 502. At this time, the stepper motor 507 is started, and the stepper motor 507 drives the gear plate seat 506 to rotate. Since the gear member 508 is meshed with the gear ring 509 and the gear plate seat 506, the stepper motor 507 can synchronously drive the gear ring 509 to rotate, so that the spoiler 511 disturbs the exhaust gas and reduces its circulation efficiency.

At this time, the exhaust gas collides with the exhaust gas filler 504 and the heat sink 505 to decelerate and condense the exhaust gas, so as to pre-treat the exhaust gas.

[0043] Step 2: During pretreatment, as the use time changes, the pressure detector 7 detects the internal pressure of the processing chamber 4. When the pressure changes, the cleaning pump 14 is started. The cleaning pump 14 transports the water in the water tank 8 to the inside of the connecting water chamber 612 through the connecting pipe 15 and the connecting piece 16, and further transports it to the inside of the guide pipe 611, and then to the inside of the connecting chamber 610, so as to be sprayed out through the cleaning nozzle 615 to clean the filler.

Since the driving gear 613 is meshed with the fixed gear ring 602, the driving gear 613 can drive the shaft member 608 and the mounting plate member 607 to rotate, and then drive the linkage rod 606 and the movable block member 605 to move, thereby changing the cleaning spray position to cool the heat sink 505 during the cleaning process.

[0044] Step 3. During use, the waste gas condensate and clean waste water fall into the collection bin 13. At this time, the delivery pump 10 is started. The delivery pump 10 delivers the waste gas condensate and clean waste water to the storage bin through the collection pipe 11 and the arc pipe 12 to complete the waste gas collection and recovery treatment, and collects and stores the clean waste water at the same time.
