[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides a copper wire continuous annealing device, which has the following beneficial effects:

[0016] (1) The utility model is provided with a preheating box, a heating cylinder and a cooling cylinder. Before use, a worker first passes one end of the copper wire through a first wire inlet provided on the box door, then opens the box door, passes the copper wire to be processed around a plurality of groups of reversing guide rollers in turn, and then passes one end of the copper wire through a second wire inlet into the inner cavity of the heating cylinder, and finally leads out through a wire outlet provided in the center of the side of the cooling cylinder and winds it around a winding sleeve. After closing the box door, the user starts the winding motor through the control panel to drive the winding shaft and the winding sleeve to rotate. Under the traction of the winding sleeve, the copper wire passes through the preheating box, the heating cylinder and the cooling cylinder in turn.

After heat exchange, the water vapor in the heat exchange condenser tube is re-condensed into cold water and flows into the return water cavity formed under the partition plate, and finally flows back to the water collecting tank through the reflux pipe for recycling.

[0017] (2) The utility model is provided with a filter screen plate and a cleaning plate.
