As shown in fig. 2, 4 and 5, the drying assembly 5 includes a blowing unit 51, a receiving unit 52, a collecting unit 53, a condensing mechanism 54, and an air supply unit 55. The blowing unit 51 is disposed above the wire in parallel with the wire fed from the cooling module 4, and the blowing unit 51 is suspended in the air in such a manner that the air flow sprayed therefrom can flow directionally from top to bottom to take away the residual cooling liquid adhering to the surface of the wire. Preferably, a receiving unit 52 capable of directing the air flow after the area where the wire is located is also provided below the blowing unit 51. Further preferably, the axially upper end opening of the receiving unit 52 is provided in such a manner as to face the air flow ejecting end of the blowing unit 51, and the axially upper end opening of the receiving unit 52 has an opening cross section larger than the air flow ejecting end face of the blowing unit 51. Preferably, the axially downward opening of the receiving unit 52 communicates with the collecting unit 53. The collection unit 53 performs gas-liquid primary separation by providing a gas permeable membrane layer 531 on an inclined bottom surface at the axially lower end thereof. Further preferably, the output end of the collecting unit 53 is further connected to a condensing mechanism 54, and the condensing mechanism 54 performs secondary separation on the liquid component carried in the airflow in a cooling and condensing manner. The output end of the condensing mechanism 54 is in unidirectional communication with the air supply unit 55 through a pressurizing pipeline 56, so that the low-temperature air output by the condensing mechanism 54 can be directionally discharged into the air supply unit 55, the output end of the air supply unit 55 is communicated with the air blowing unit 51, and the stored high-pressure air is further directionally output through the air blowing unit 51.

Preferably, a plurality of injection ports 512 are arranged at intervals on the bottom surface of the output pipe chamber 511 of the blowing unit 51. The jet ports 512 are arranged at intervals in the axial direction of the output pipe chamber 511, and the caliber of the jet ports 512 is changed in a gradient along the axial direction of the output pipe chamber 511, so that the air flow output by the jet ports 512 can be jetted in a way that the air flow pressure is gradually increased. Preferably, the end of the pipe line, through which the air supply unit 55 communicates with the air blowing unit 51, is provided with a pressure valve so that the air pressure received by the air blowing unit 51 is high enough to form an air flow capable of effectively separating the residual cooling liquid on the surface of the wire. Preferably, the gas output by the gas supply unit 55 may be an inert gas such as nitrogen, so that in the case of filling the chamber formed by the whole annealing body 2 with the gas, the possibility of oxidation of the wire due to the excessively high temperature of the wire can be effectively reduced, thereby providing the wire with better electrical conductivity. Specifically, the input end of the output tube chamber 511 is disposed at a side of the air blowing unit 51 away from the cooling module 4, and the aperture of the injection port 512 is increased stepwise from an end away from the cooling module 4 to an end close to the cooling module 4, so that the air flow intensity of the environment in which the wire passed out from the cooling module 4 is located is increased stepwise.

As shown in fig. 2 and 4, a flat nozzle 513 is connected to the output end of the injection port 512. The long diameter direction of the flat nozzle 513 is parallel to the length direction of the metal wire, so that the air flow output by the air blowing unit 51 can accurately cover the metal wire in a more effective and wider area, waste and ineffective air blowing of a large range of air flow are avoided, and the flat nozzle 513 sets the caliber size of gradient change in a mode of constructing the same proportion as the jet orifice 512. Preferably, the larger the flat mouth dimension of the flat mouth nozzle 513 closer to the cooling assembly 4, such that the flat mouth nozzle 513 further from the gas inlet port is still capable of a directional injection capability. Preferably, the jet orifice 512 and the flat orifice nozzle 513 are sized to define a wire section distal from the cooling module 4 that is more resistant to air flow than a wire section proximal to the cooling module 4, thereby forcing the wire to quickly separate the residual cooling fluid from the wire under the air flow in a vertical direction perpendicular to the length direction of the wire with a gradient of increased air flow, thereby effectively achieving air drying of the wire. The air drying mode can effectively and continuously dry the metal wire, so that the device can continuously dry the metal wire along with the continuous annealing process, and the production efficiency of the metal wire is effectively improved. The gradient type jet orifice and the flat orifice jet nozzle can blow and dry the same metal wire through continuous multi-stage air flow, so that the drying effect is far stronger than that of an adsorption cotton process, the device does not need to regularly disassemble, assemble and replace adsorption cotton, and the sustainable use efficiency is improved. Compared with simple blowing and drying by a fan, the pressurized air flow and the flat-mouth nozzles which are arranged in a collinear way at intervals can effectively act on the metal wire with a small section, so that the liquid on the surface of the metal wire can be effectively separated.

Preferably, the receiving unit 52 includes an open chamber 521, an interception breathable layer 522, a flow-guiding support layer 523, and a baffle 524.

Preferably, the collecting unit 53 is further provided with a flow guiding unit 57 so that it can provide a directional driving force for the gas passing through the interception and ventilation layer 522. The interception and ventilation layer 522 and the diversion support layer 523 provided by the utility model can buffer the airflow and the liquid carried by the airflow, so that the liquid can be effectively contained in the opening cavity 521, and the gas-liquid separation can be realized to a certain extent through the buffering and decelerating process. In addition, at the time of matching

As shown in fig. 5, a plurality of condensation columns 542 are arranged in the middle of the condensation chamber 541 of the condensation mechanism 54. The condensation column 542 can be cooled by the cooling unit 543 such that the condensation column 542 can remove liquid components in the gas stream in a condensed manner, thereby drying the gas. Preferably, the dried low-temperature gas can flow into the gas supply unit 55 in one direction through the pressurizing pipeline 56 again, so that the gas supply unit 55 can continuously output the low-temperature dried gas flow, and the air-cooled drying of the gas flow on the metal wire is realized. Preferably, the low-temperature drying air flow can effectively take away liquid components on the surface of the metal wire, and meanwhile, the structural stability of the metal wire on a crystal level can be ensured, so that the performance of the metal wire is prevented from being influenced by the change of the material of the metal wire.
