Background Technology

[0002] Continuous surface treatment production lines are used to surface treat bar stock workpieces. The workpieces pass through a continuously replenished tank filled with liquid, and the tank is sealed by sealing arrays at both ends. Return pipes at the bottom of both ends allow excess liquid to slowly flow back into the tank, ensuring the bar stock workpieces are always immersed in liquid. Further processing strengthens the surface of the workpieces. Current industry practice involves configuring cylindrical sealing arrays at both ends of a tank. This method requires manual assembly of the sealing sleeves beforehand, followed by installation by multiple people into the sealing grooves at both ends of the tank, which is time-consuming and labor-intensive. Some improvements have adopted insert-plate sealing arrays, but these suffer from severe deformation, significant leakage, inconvenient installation of the insert seals, and inability to guarantee product quality.
