Embodiment Construction
[0024] In order to facilitate understanding of the present invention, the present invention enumerates the following examples. It should be clear to those skilled in the art that the embodiments are only for helping to understand the present invention, and should not be regarded as specific limitations on the present invention.
[0025] A kind of turbocharger aluminum impeller cleaning process, it comprises the following steps:
[0026] 1) Classification: after dismantling the aluminum impeller from the scrapped turbocharger, sort out qualified products and scrapped products according to their appearance;
[0027] 2) Soaking: Soak the aluminum impeller with a liquid containing a cleaning agent. During the soaking process, the soaking liquid should submerge the entire aluminum impeller, remove easy-to-fall oil, dust and other foreign matter, and soften stubborn oil and other foreign matter; the soaking in this step Add a neutral aluminum alloy cleaning agent to the solution, t...

The invention provides a turbocharger aluminum impeller cleaning process. The process comprises the following steps of 1) classifying; 2), soaking; 3), washing; 4), ultrasonic cleaning; 5), premier rinsing; 6), removing mildew and spot ultrasonic cleaning; 7) removing oxidation layer ultrasonic cleaning; 8), secondary rinsing; 9), passivating; and 10), drying. According to the turbocharger aluminum impeller cleaning process, the discharge amount of wastewater discharged to a sewage treatment station in a cleaning process is greatly reduced, the cleaning wastewater is treated by the sewage treatment station and is not directly discharged, the cleaning wastewater can be recycled or discharged to the environment after being treated, so that the environmental pollution is remarkably reduced; and meanwhile, oil stains, mildew spots, oxidation layers, dust and other foreign matters on the aluminum impeller can be effectively and thoroughly removed, the recycling rate of the aluminum impelleris improved, the energy is effective saved, the material is saved, the cost is saved, the wastewater discharge amount is greatly reduced, and the development of the sustainable health of the turbocharger industry is powerfully promoted.
Description
technical field [0001] The invention belongs to the recovery and reuse technology of a turbocharger, in particular to a cleaning process for an aluminum impeller of a turbocharger. Background technique [0002] Our country has entered the automobile society. A large number of automobiles are scrapped every year, and the turbochargers used for these scrapped automobiles are also scrapped. After these scrapped turbochargers are disassembled, the surface of the aluminum impeller has a lot of oil stains, mildew spots, and oxide layers. , dust and other foreign matter, currently there are basically two treatment methods for aluminum impellers: one is to use aluminum impellers for simple oil cleaning, lack of research and consideration for surface mildew and oxide layers, oil cleaning is not very ideal The waste water is high and the waste water discharge is large, which pollutes the environment greatly and cannot meet the requirements of recycling and reuse; the second is to retu...
