Description

[Detailed Description of the Invention] The present invention relates to an improvement of a continuous surface treatment device for wire materials, such as a continuous plating device.

In a continuous plating device for wire material, the alkaline degreasing liquid tank, washing liquid tank, pickling liquid tank, washing liquid tank, plating liquid tank, and washing liquid tank are connected to each other from the supply side of the wire material. They are provided sequentially toward the receiving side, and on both sides of each tank, as shown in Fig. 1, there are stripes on the front and rear walls 21', 22', . . . of each tank 1', 1'', . Liquid receiving parts 31', 32', ... are provided to receive the liquid flowing out from the material passage slits s', .... The liquid that can flow into these liquid receiving parts 31', 32', ... is pumped P. ′, . . . are returned to the tank portions 1 ′, .
4', . . . are partition walls between the liquid receiving parts 31', 32'', .

In the above, the liquid level in the liquid receiving part decreases as it approaches the partition wall 4', and near the partition wall, it is completely isolated below the wire material a', but the wire material is vertically oriented in cross section. If it is a strip, even if the strip leaves the liquid surface, the liquid will adhere to both sides of the bottom end of the strip due to its surface tension, and in this state, the strip will move to the next one. If the liquid enters the processing tank, contamination of the processing tank is unavoidable.

The continuous surface treatment device for wire materials according to the present invention has a configuration that can easily prevent the above-mentioned liquid contamination, and has a plurality of treatment tank sections in tandem, and the front and rear walls of each treatment tank section have a wire strip on the front and rear walls. In a device that has a slit through which the material passes, and a liquid receiving section at the front and rear of each processing tank section, an air current is blown onto the wire material through the front liquid receiving section at the rear processing tank section of the processing tanks that are placed in front of each other. This is characterized by the fact that it is equipped with an attached blower.

The present invention will be explained below with reference to the drawings.

FIG. 2A is an explanatory longitudinal cross-sectional view showing the device of the present invention.

In FIG. 2A, numerals 1, 10, . . . are processing tank sections arranged in tandem, and the figure only shows two sections that can be placed one behind the other. 21, 22, . . . are the front and rear walls of each tank portion 1, . . ., and are provided with slits s, . 31, 32, . . . are liquid receiving portions provided on both sides of each tank portion 1, . . . , and 4, . . . are partition walls. P,... are pumps. Reference numeral 5 denotes an air blower installed near the partition wall 4 in the front liquid receiving section 31 of the rear (fiber material supply side) processing tank section 1 of the processing tank sections 1 and 10 which are arranged in front of each other. It is located below the passing wire material a.

In the above, the liquid level is low near the partition wall 4, and the liquid level is below the filament a, but the filament a is a strip with a vertical cross section as shown in Figure 2B. In some cases, the liquid from the rear processing tank tends to adhere to the lower end of the strip, and if the strip enters the next front processing tank 10 in this state, the liquid in that processing tank 10 tends to stick to the lower end of the strip.
liquid contamination is unavoidable.

However, in the present invention, the adhering liquid can be scattered and removed by an air blower, and the strip can be transferred to the next front processing tank section 10 without any adhering liquid, thereby reliably preventing the above-mentioned liquid contamination. can.

As described above, according to the present invention, it is possible to reliably prevent liquid contamination in a continuous surface treatment apparatus having a plurality of tandem treatment tank sections for different liquids, and there is an advantage that high-quality surface treatment can be guaranteed.
