[0002] In existing technology, oil-immersion dryers are commonly used to dry workpieces after surface treatment. The principle is to use an air knife to sweep the workpiece back and forth in a closed (squirrel cage) space to dry any residual oil on the workpiece surface. However, this method has the following shortcomings in practice:
[0003] 1. Its closed (squirrel cage) structure is not conducive to realizing automatic functions on the surface treatment production line.
[0004] 2. The air knife can only be set around the equipment and perform reciprocating motion. After the batch of workpieces are immersed in oil, if the gap between the workpieces is small, the oil drainage effect is not good.
[0005] 3. The equipment is not equipped with shaking or tilting (swinging) function. After the batch of workpieces are immersed in oil, such as stacked workpieces, overlapping workpieces, and workpieces with holes, residual liquid is easily accumulated, and the oil drainage effect is poor.
