Problems solved by technology

However, it is difficult to remove the floating or adhering dirt on the surface of the sealing liquid and the insulating plastic ball. When the workpiece is lifted out of the sealing liquid, the dirt will adhere to the surface of the workpiece, making the workpiece need to be stripped and re-oxidized , closing and other rework processes

Embodiment Construction

[0004] Use compressed air to pass into the bottom of the closed liquid, and use compressed air to stir the closed liquid. There is a filter pump at the bottom of the closed liquid tank to circulate and filter the dirt in the closed liquid. Regularly remove the plastic balls used for heat preservation and rinse them separately. Remove the dirt on its surface and shorten the filter cycle of the filter pump.

Abstract

The invention relates to a filtration method of an aluminum alloy oxidation blocking solution. According to the invention, plastic balls for thermal preservation are distributed on an aluminum alloy oxidation blocking solution surface. Compressed air is employed to stir the blocking solution. A filtration pump is disposed at the bottom of a liquid groove to conduct circulating filtration of dirt in the solution. The plastic balls for thermal preservation are got out regularly for washing separately to wash the dirt on the surfaces away, thus avoiding a rework treatment on a workpiece due to adhesion of dirt on the workpiece surface while getting the workpiece out of the blocking solution.

Description

technical field [0001] The invention belongs to a method for filtering an aluminum alloy oxidation sealing solution, in particular to a method for filtering an aluminum alloy oxidation sealing solution which can improve the filtering effect. Background technique [0002] At present, when the known aluminum alloy oxidized sealing liquid is filtered, the surface of the sealing liquid is covered with plastic balls for heat preservation, and the sealing liquid is stirred with compressed air, and a filter pump is arranged at the bottom of the liquid tank to circulate and filter dirt in the sealing liquid. However, it is difficult to remove the floating or adhering dirt on the sealing liquid and the surface of the insulating plastic ball. When the workpiece is lifted out of the sealing liquid, the dirt will adhere to the surface of the workpiece, making the workpiece need to be stripped and re-oxidized , Closure and other rework processes. Contents of the invention [0003] In ...
