Each of the external damping brackets 34 has external damping plates a, b (31, 35) fixedly connected thereto, and the strainer housing 41 fixedly connected to the circular ring frame 39 has eight circular holes. A funnel-shaped strainer 19 is fitted in the circular hole of the bolt and connected to the strainer housing 41. The inner inner portion of the funnel strainer 19 is bolted to the ring bracket 43 and the ring bracket 43 is connected to a plurality of ring connecting brackets 50, which are fixedly connected to the strainer housing 41. The ring connecting bracket (50) is a space portion of the through-hole 42, the ring bracket b (30) is fixed to the sides of the strainer housing 41, the ring bracket b (30) is fixed to each other and bolted to the inside The damping guiding ring plate a 25 is bolted to the ring bracket a 24 which is fixedly connected. Damping guiding ring plates a, b (25, 29) between the damping guiding plate 49 is composed of eight bolted connection respectively, the main ring frame (46) on both sides of the main ring cover 54 is bolted It is configured to be assembled and connected.

When the plating solution supplied by the plating solution supply pump (not shown) is supplied through the solution supply pipe 26 during the continuous electroplating operation, the plating solution is connected to the connection pipe b (27), the circular hole c, d ( 23, 28, flows through the funnel strainer 19, foreign matter in the plating solution is filtered by the strainer (19). The filtered plating solution is supplied to the anode positive pressure nozzle 12 through the through hole 42, the circular hole e 33, and through the connecting pipe c 32 and the positive pressure nozzle pipe 3, thereby performing a normal plating operation. . Figure 6 (a) is a cross-sectional view showing a state in which the foreign matter is filtered through the strainer plating solution supplied by the solution supply pump, Figure 6 (b) is a cross-sectional view showing the action of moving the strainer one space in the arrow direction 6 (c) is a cross-sectional view showing a state in which pure water is supplied to a strainer and foreign substances are dropped out and discharged to the outside, and FIG. 7 is a cross-sectional view showing an operating state according to an embodiment of the present invention. Referring to FIG. 6 (a), when the weld (not shown) of the continuously welded strip 1 passes through the corresponding plated anode 5 of the plating cell 2, the motor 20 is operated. The operation of the 20 is stopped when the limit contact 51 is sensed by the limit switch 52. In this state, the funnel strainer 19 is moved by one column in the direction of the arrow. As shown in FIG. 6C, the funnel strainer 19 is moved by one cell in the direction of the arrow. The automatic valve a 14 is opened and at the same time the automatic valve b 44 is opened so that the pure water flows in the reverse direction of the funnel strainer 19 through the circular hole f 47 and the through hole 42. When the pure water flows, a flushing action occurs, and the foreign matter 11 in the strainer 19 falls off, and the foreign matter 11 is discharged to the outside through the automatic valve a 14 and the drain pipe 13. Since the damping guiding ring plates a and b (25 and 29) and the damping guiding plate 49 come into contact with the outer damping bracket 34 and the outer damping plate a and b (31 and 35), they act as a seal. The plating solution is not mixed. By the above-described action, the plating solution continuously passes through the funnel strainer 19, and a filtering action occurs in which the foreign matter is filtered out. After a predetermined time, the funnel strainer 19 assembled in a circular position is installed in the direction of the arrow. You will move one space. Since pure water is supplied in a direction opposite to the direction in which the plating solution flows, backwashing and flushing occur to remove foreign substances in the funnel strainer 19.
