Description

DESCRIPTION OF THE FIGURES

(1) FIG. 1 is a top elevational represent view of the holding members of the inventive washing assembly.

(2) FIG. 2 is a top elevational represent view of the wiper pair of the inventive washing assembly.

DETAILED DESCRIPTION OF THE INVENTION

(3) Referring to FIG. 1, there are a washing assembly (1) in the production of sheet metals (4) used in the production of double-layered and copper-coated pipe, a coating container (2) in which the previous process of washing has been applied in the washing assembly (1) and a coating container (3) in which the next process of washing has been applied. The sheet metal (4) is subjected to copper coating process in a coating container (2) by electrolysis method using a cyanide copper coating solution. The sheet metal (4) coming out of the coating container (2) passes through an inlet (18) and reaches the washing assembly (1) as it progresses in a forward direction (F). In the washing assembly (1) the sheet metal (4) free of chemical, passes through an outlet (19) and forward to the lacquering container (3) for being subjected to lacquering.

(4) The washing assembly (1) is surrounded by an outer wall (11) forming the outer periphery and has a rectangular shape similar to the periphery when viewed from above. At least one washing chamber (13) is provided on the inside of the washing assembly (1). The washing chamber (13) extends from the back of the washing assembly (1) and at least the sheet metal (4) passes through it. In the washing chamber (13) there is a washing liquid. In the preferred embodiment, said washing fluid is a demineralised water. On both sides of the washing chamber (13), there is at least one partition (12) which is situated opposite to each other. In a more detailed manner, the partitions (12) are positioned on both sides of the washing chamber (13) so as to be symmetrical about the axis of movement of the sheet metal (4). In a possible embodiment, each partition (12) is equal to each other. The partitions (12) are separated from each other by at least one inner wall (121) extending in a direction perpendicular to the forward direction (F) of the sheet metal (4).

(5) The washing chamber (13) has at least one wiper pair (14). The wiper pair (14) comprises two holding members (15) extending linearly opposite to each other and two wiping members (17) located in the holding members (15). In a possible embodiment, an endpiece of the inner walls (121) extending into the washing chamber (13) is a holding member (15). In each holding member (15) there is at least one channel (151) which opens into the washing chamber (13). The channel (151) has a front part (152) having a width such that a free end (175) of the wiping member (17) can pass. A rear part (153) of the channel (151) is structured to be wider than the front part (152).

(6) Referring to FIG. 2, a wiping member (17) is located in the channel (151) of each holding member (15) in the washing assembly (1). In a more detailed description, locating an end part (171) of wiping member (17) into the channel (151) is provided in the form of a tight fit. In a possible embodiment, the end part (171) is in the form of a projection. The free end (175) of the wiping members (17) has a folding part (173). The free end (175) is in a twisted form, approximating the sheet metal (4). Due to the folding part (173) of the wiping member (17), the free ends (175) of the mutually located wiping member (17) extend in close proximity. The free ends (175) have at least one contact surface (174) in contact with the surfaces of the sheet metal (4) during the movement of the sheet metal (4). In the washing chamber (13), there is at least one front wall (16) which supports a folding part (173) of the wiping member (17). In a possible embodiment, the front wall (16) extends from a corner of the holding member (15) to the folding part (173) of the wiping member (17). The front walls (16) are positioned symmetrically with respect to the axis of movement of the sheet metal (4) and close to the inlet (18) of the washing chamber (13).

(7) During the movement of the sheet metal (4) in the forward direction (F), the surfaces of the sheet metal (4) are stripped together with the washing liquid as they pass through the gap between the wiper pair (14). In this way, the sheet metal (4) passing through the plurality of wiper pair (14) is stripped by the number of the wiper pair (14). In a case where the washing assembly (1) is cleaned or the wiping members (17) have to be replaced, the wiping members (17) are placed in the partitions (12). In the case where the sheet metal (4) is going through, the wiping members (17) are placed in tight contact into the channel (151) of the holding members (15) so that the washing assembly (1) is ready for washing.

(8) In a possible embodiment, the wiping member (17) is produced from a flexible material, and in a more probable embodiment, from a rubber material.
