[0039] The surface treatment device 2 includes a first cleaning tank 21, a water washing tank 22 and a second cleaning tank 23 which are arranged in sequence along the conveying direction;

[0040] The first cleaning tank 21 includes a first box body 201, an electrolyte assembly and a liquid inlet assembly 204. The electrolyte assembly is arranged in the first box body 201 and is spaced from the inner wall of the first box body 201. The electrolyte assembly includes an upper tank body 202 and a lower tank body 203. The upper tank body 202 is provided with an upper accommodating cavity 2021 and a through hole 2022. The lower tank body 203 is arranged below the upper tank body 202 and is connected to the upper tank body 202 to form a sealed cavity 2023. The through hole 2022 communicates the upper accommodating cavity 2021 and the sealed cavity 2023. One end of the liquid inlet assembly 204 communicates with the sealed cavity 2023.

[0041] Specifically, in this embodiment, the feeding device 1 is used to carry the filament coils to be processed from the outside. The surface treatment device 2 includes a first cleaning tank 21, a water washing tank 22, and a second cleaning tank 23 that are connected in sequence. The electrolyte in the first cleaning tank 21 is alkaline water solution, the water washing tank 22 is used to hold clean water, and the electrolyte in the second cleaning tank 23 is acidic water solution. The drying device 3 is arranged behind the second cleaning tank 23 and heats the filament from the outside after surface treatment to remove the liquid on the filament surface. The detection device 4 detects the diameter of the filament after cleaning and drying. The qualified filament is collected by the collecting device 5; preferably, the feeding device 1 is provided with eight reels, and one reel carries one filament coil from the outside. Eight electrolyte assemblies are installed in the first box body 201, and the eight electrolyte assemblies are arranged in parallel at intervals. Each electrolyte assembly includes an upper tank body 202 and a lower tank body 203. The cross-section of the upper tank body 202 is U-shaped, and the cross-section of the lower tank body 203 is U-shaped. The length specification of the lower tank body 203 is smaller than that of the upper tank body 202, and the width specification of the lower tank body 203 is smaller than that of the upper tank body 202. The lower tank body 203 and the upper tank body 202 are connected to form a sealed cavity 2023. The liquid inlet assembly 204 includes a pump body and a pipe body, and the outside electrolyte is transported to different sealed cavities 2023 through the pump body and the pipe body. The specific working principle is as follows: the outside alkaline water solution first flows into the sealed cavity 2023 through the liquid inlet assembly 204, and then the alkaline water solution flows into the upper accommodating cavity 2021 through the through hole 2022, so that the outside alkaline water solution slowly flows into the upper accommodating cavity 2021, thereby making the alkaline water solution in the upper accommodating cavity 2021 slowly increase, reducing the fluidity of the alkaline water solution, and thus avoiding the visual error caused by the fluidity of the alkaline water solution to the liquid level height after the alkaline water solution is poured into the upper accommodating cavity 2021, ensuring the consistency of the volume of the alkaline water solution in each upper tank body 202, so as to improve the stability of the cleaning quality of the outside filament surface. The filament after passing through the first cleaning tank 21 sequentially enters the water washing tank 22 to complete water cleaning, and finally enters the second cleaning tank 23 filled with acidic water solution to complete the surface cleaning process of the filament. Then the filament is dried by the drying device 3, and the detection device 4 detects the radial specification of the filament to detect whether the surface treatment result of the filament meets the standard. Finally, the filament is wound up by the collecting device 5.

[0042] By setting up a surface treatment device 2 composed of a first cleaning tank 21, a water washing tank 22 and a second cleaning tank 23, a first cleaning tank 21 composed of a first box body 201, an electrolyte assembly and a liquid inlet assembly 204, an electrolytic tank assembly composed of an upper tank body 202 and a lower tank body 203, the upper tank body 202 is provided with an upper accommodating cavity 2021 and a through hole 2022, the upper tank body 202 and the lower tank body 203 are connected to form a sealed cavity 2023, the sealed cavity 2023 has the function of storing liquid, the external electrolyte flows into the sealed cavity 2023 through the liquid inlet assembly 204, and then enters the upper accommodating cavity 2021 through the through hole 2022, reducing the flow rate of the electrolyte in the upper accommodating cavity 2021, avoiding misjudgment of the electrolyte volume caused by visual error of the electrolyte liquid level, ensuring that the volume of the electrolyte entering each upper accommodating cavity 2021 is the same, so as to improve the stability of the surface cleaning quality of the external wire body and the controllability of the quality qualification rate.

[0044] The long side plate is provided with several upper notches 2024. The upper notches 2024 start from the upper surface of the long side plate and extend towards the bottom plate. The distance between adjacent two upper notches 2024 is set. When the upper surface of the alkaline water liquid flowing into the upper accommodating cavity 2021 exceeds the upper notch 2024, the alkaline water liquid overflows through the upper notch 2024 and flows into the first box body 201, and the first box body 201 recycles the alkaline water liquid.

[0045] The upper tank body 202 further includes several inner partition plates 207. The several inner partition plates 207 are arranged in the upper accommodating cavity 2021 along the length direction of the upper accommodating cavity 2021.

[0047] The first cleaning tank 21 further includes a second box body 205, a third box body 206, and a liquid collecting pipe. The third box body 206 is located below the first box body 201. The two ends of the liquid collecting pipe are respectively communicated with the first box body 201 and the third box body 206. The second box body 205 is located below the third box body 206. The other end of the liquid inlet assembly 204 is communicated with the second box body 205.

The heating element 32 is arranged at the inner bottom of the heat preservation box body 31. The setting of the heating element 32 accelerates the evaporation of the liquid on the surface of the wire body, improves the production efficiency, and shortens the length of the tungsten-molybdenum wire whitening machine production line.

[0049] The heating element 32 is in a concave arc shape, having a heat accumulation effect and improving the utilization rate of heat energy.

[0050] The detection device 4 includes a guide rail 41, a mounting seat 42, and a wire diameter measuring member 43.
