Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. FIG. 2 shows a first embodiment of the present invention in which the surface-treated material (2) is a wire. On both sides of the T-tube (10), a guide outer cylinder (1
1) is fitted into the T-tube (10) with the first cap nut (12), and the space between the guide outer cylinder (11) in the T-tube (10) is a jet. This is a jet expansion space (1). To describe the jet jet expansion space (1), the space may be cylindrical or rectangular. In the figure, a portion extending below the T-tube (10) is a discharge hole (9) that opens from the jet jet expansion space (1) to the outer surface.
It is. Insert the inner cylinder insertion hole (1
A guide inner cylinder (14) is screwed into this inner cylinder insertion hole (13) so as to be able to advance and retreat. The bottom (15) of the inner cylinder insertion hole (13) is formed in a mortar shape, and a jet jet passage hole (5) leading from the hole bottom (15) into the T-tube (10) is inserted into the guide outer cylinder ( It is drilled in the center of 11). The insertion side end of the guide inner cylinder (14) is shaped like a needle valve, and the tip of the needle valve (16) is also tapered.
A slight gap is formed between the needle valve (16) and the hole bottom (15) to form a fluid ejection hole (8), and the fluid ejection hole (8) and the introduction hole (3) or The angle (θ) formed with the outlet hole (4) is an acute angle of about 15 to 60 degrees. The gap between the fluid ejection holes (8) is adjusted by the screwing amount of the guide inner cylinder (14). After the adjustment, the adjustment nut (17) is tightened and fixed. Since the needle valve (16) has a considerably smaller diameter than the inner cylinder insertion hole (13), a fluid reservoir (18) is generated around the needle valve (16). The following is an important point of the present invention. As shown in Fig. 3.4, the tip of the needle valve (16) is cut off slightly obliquely with respect to the center line (CL). ) And the bottom of the hole (15), the opening of the fluid ejection hole (8) is narrowed on one side, and the opening width is gradually increased from the narrow opening toward the other. . The cut-off angle (α) at the tip of the needle valve (16) is about 2 ° to 15 °. Fifth
FIG. 7 shows another embodiment, and FIG. 5 shows a needle valve (16).
This is an example in which the tip of the fluid ejection hole (8) is cut off stepwise, and a part of the opening of the fluid ejection hole (8) is formed narrow and the other is widened. In FIG. 6, the tip of the needle valve (16) is formed in an irregular shape (saw blade in the illustrated embodiment).
It becomes caught in the water film which can be ejected from the convex part. In FIG. 7, the opening width of the fluid ejection hole (8) is partially increased by shaving off the opening edge of the hole bottom (15). The fluid reservoir (18) is provided with a fluid supply hole (19) communicating with the outside. A ceramic nozzle (20), a carbide nozzle (20), and an abrasion-resistant resin nozzle (20) are fitted into the end of the guide inner cylinder (14) to improve abrasion resistance. Secured at (21). Of course, the nozzle (20) may be attached by press fitting. The center of the nozzle (20) and the guide inner cylinder (14) is formed according to the outer shape of the wire,
The jet is slightly larger than the outer diameter of the wire rod (that is, the gap is such that the inside of the introduction hole (3) and the outlet hole (4) becomes a negative pressure due to the flow velocity of the jet jet and the fluid (7) does not flow backward). An inlet hole (3) and an outlet hole (4) each having an inner diameter slightly smaller than the jet passage hole (5) are formed. As the fluid (7) supplied to the fluid supply hole (19), for example, a polishing liquid or a lubricating liquid containing a cleaning solvent such as trichlene, water, a detergent or a fine abrasive is used.

First, a case where cleaning is performed by the present apparatus will be described.
As shown in FIG. 1, a compressor (23) is connected to a fluid supply port (19) via a filter (22), and a discharge port (9) is connected.
To the cyclone (24). Next, the linear surface-treated material (2) is inserted from the introduction hole (3) into the outlet hole (4), and the surface-treated material (2) is moved in one direction on the pass line (B) at a constant speed. Send. When the cleaning liquid is sent from the cleaning pump (23) to the surface treatment device (A) at the same time as the supply of the surface-treated material (2), the clean cleaning liquid passed through the filter (22) is temporarily stored in the fluid reservoir (18). And then is rapidly fed into the jet jet passage hole (5) from the thin fluid ejection hole (8). The cleaning liquid passes through the jet jet passage hole (5) at a rapid speed to brush the surface of the surface-treated material (2), and to blow off dirt on the surface. At this time, as shown in FIG. 3, a water film composed of a strong water flow is ejected from the narrow opening of the fluid ejection hole (8) toward the center of the surface-treated material (2), and the surface to be treated is exposed. The cleaning liquid from the wide opening portion diffuses to some extent and does not strongly collide with the watering. It flows toward the jet jet expansion space (1) in the jet jet passage hole (5).

On the other hand, in the portion of the inlet hole (3) and the outlet hole (4), a negative pressure is created by the flow of the cleaning liquid in the jet jet passage hole (5), and the outside air flowing into the inlet hole (3) and the outlet hole (4). As a result, brushing also occurs in this portion. In particular, outside air flows in a direction opposite to the surface-treated material (2) in the outlet hole (4), and the flow velocity of the outside air flowing on the surface of the surface-treated material (2) becomes relatively high, so that the draining / drying effect is significantly enhanced. Things. In other words, the wiper effect is exhibited by utilizing the inflowing outside air. Thus, the cleaning liquid reaches the jet jet expansion space (1), decelerates at the center of the jet jet expansion space (1), advances to the discharge hole (9), and enters the cleaning liquid storage tank (24). When entering the cleaning liquid storage tank (24), foreign matter is separated, and the clean cleaning liquid is reused.

Even if the surface-treated material (2) has a cross section that is not circular but has an intricate shape, a jet jet of trichlene is blown into the inner part to realize complete cleaning. When tricrene is supplied from the left and right fluid supply holes (19),
In the jet jet passage hole (5) on the outlet hole (4) side,
The flow rate of trichlene flowing on the surface of the wire becomes relatively high, which enhances the cleaning effect. When the wire passes through the jet flow passage hole (5) and enters the outlet hole (4), the surface of the wire is brushed by the external air flow sucked by the negative pressure of the outlet hole (4) and dried.

(Effect) In the present invention, an inlet hole and an outlet hole that are opened on the outer surface of the device main body are provided in the device main body, and a jet jet passage hole is formed following the inlet hole and the outlet hole. Since a fluid ejection hole is formed at the boundary of the boundary of the jet jet passage hole and the outlet hole, and a part of the opening to the boundary of the fluid ejection hole is formed wider than the rest of the opening portion, As shown in FIG. 3, a water film composed of a strong water stream is ejected from the narrow opening portion of the fluid ejection hole toward the center of the material to be treated and collides with the material to be treated. The cleaning liquid from the widened part diffuses to some extent, does not violently collide with the strong water film, and does not reversely flow because it is caught in the opposite direction. It flows toward the expansion space. As a result, a part of the cleaning liquid does not leak out from the introduction hole or the discharge hole unlike the related art, and the cleaning operation can be performed with the surrounding environment kept beautiful.

In addition, since the jetted cleaning liquid passes through the jet jet passage hole at a rapid speed, the surface of the material to be treated is brushed violently in the jet jet passage hole to blow off moisture and dirt on the surface and clean the surface. At the same time, it comes into contact with the suction outside air at the outlet hole, evaporating the liquid on the surface, and has the advantage that cleaning and drying of the surface can be performed continuously by a single process. Is advantageous in that excess lubricating oil and rust-preventive oil are stripped off at the portion of the lead-out hole, and uniform coating can be performed. In addition, since the inner diameter of the inlet hole and the outlet hole is smaller than that of the jet jet passage hole, a negative pressure is generated by the flow of the fluid in the jet jet passage hole, and the outside air flowing into the inlet hole and the outlet hole causes this pressure. The surface is brushed even in the part, and there is an advantage that the cleanliness and the dryness of the surface can be improved. In addition, since the fluid is ejected from both the inlet side and the outlet side into the jet jet expansion space, the washing liquid coming from the inlet side and the washing liquid coming from the outlet side collide at the center. As a result, the flow velocity is reduced, and subsequently the flow proceeds to the discharge hole, so that the device shape can be made compact.
