[0002] After oxidation, the surface of industrial aluminum profiles has a very beautiful appearance and is resistant to dirt. Once coated with oil, it is very easy to clean. When assembled into products, profiles of different specifications are used according to different load-bearing. The profiles need to be passivated during the production process. The process of using chromate solution to react with the profile to form a trivalent or hexavalent chromium layer on its surface is also called chromization. It meets the processing needs of aluminum, magnesium and their alloys.

[0003] The utility model discloses an environmentally friendly aluminum alloy passivation treatment device (CN209162191U), comprising a treatment box and a neutralization tank, wherein the bottom of the treatment box is fixed to the top of a base frame by bolts, a neutralization tank is horizontally installed in the middle of the inner side of the base frame, an interface at the top of the neutralization tank is connected to the center position of the bottom of the treatment box by a conduit, and two groups of first hydraulic cylinders are vertically fixed corresponding to the middle positions on both sides of the treatment box. The utility model uses a gas hood on the top of a top cover to enter the interior of the gas treatment box, and an axial flow fan on one side of a sealing box of the gas treatment box generates suction to suck gas into a calcium hydroxide filling layer of a filter box to neutralize the volatile acid gas, thereby protecting the environment; a control valve is used to control the alkaline solvent in the solvent box to be injected into the interior of a wastewater tank to neutralize the waste liquid, thereby protecting the environment; a second hydraulic cylinder is used to control the up and down movement of a pull rod, and the up and down movement of the pull rod drives a support plate to rotate, and the placement and removal of aluminum alloy profiles are controlled by the rotation of the support plate, thereby improving the efficiency of the passivation operation of the aluminum alloy profiles. However, in use, the aluminum profiles are mostly pulled manually and introduced into a chromate solution pool for passivation treatment. This operation method has limited production efficiency of aluminum profiles. At the same time, during the mass production of aluminum profiles, the labor intensity of workers is high, which is inconvenient for users.
