Abstract

The invention relates to a surface pre-treatment system combining four aluminum alloy working grooves into a whole for full recovery of medicament and zero emission of wastewater. The surface pre-heated system comprises a No.1 four-in-one sand surface groove, a No.2 matte tank, a No.3 water washing interception groove, a No.4 water washing interception groove, a No.5 water washing interception groove, a No.6 water washing material waiting groove, a No.7 oxidation groove and a No.8 water washing interception groove, as well as a matching slag pumping system, a medicament recovery system, a water circulation purification processing system and a reverse water replenishing neutralization system. As the four working grooves are combined into a whole, and the technical scheme is simultaneously equipped with the full recovery of the medicament and the zero emission of the wastewater, the pollution of fluorine and ammonium in the oxidation pre-treatment of an aluminum alloy anode can be effectively solved, the full recovery of the wastewater in the aluminum alloy surface pre-treatment can be realized, the pollution control of a company can be greatly reduced, and the production cost can be reduced.

Description

technical field [0001] The invention belongs to aluminum alloy surface treatment technology and environmental protection technology, and specifically relates to an aluminum alloy surface pretreatment system with fluorine-free and ammonium-free medicaments, four working tanks in one slot configuration, full recovery of reaction medicaments, and zero discharge of cleaning wastewater. technical background [0002] Aluminum alloy surface pretreatment processes are mainly divided into two categories: alkali etching and acid etching. The existing aluminum profile alkali etching process has been used for more than 100 years. Alkali etching has the disadvantages of high aluminum consumption, high alkali consumption, more alkali slag, difficult process control, many defects, high production cost, and large environmental pollution. The standard alkali etching tank layout is as follows: figure 1 As shown, 1#, 4#, 7#, 11# and 14# tanks are working tanks, each working tank is equipped w...
