Pass at least one acid leaching area and at least one sprayer nozzle or adjacent cleaning area in which the sprayer is provided for cleaning the medium and at least one pair of squeeze rollers. [Prior Art] In the acid leaching equipment that has been established so far, spots on the surface of the belt are formed due to the dwelling of the acid leaching medium on drying and oxidation of the belt continuously fed through the equipment during normal operation. Therefore, a system was developed to allow the metal band to overflow in the event of a pause in the band, however, $ means that a large amount of cleaning medium is needed, and the cleaning area must be suitable to cope with this large amount of medium. On the other hand, it has been suggested that if the belt stops, inert or noble gases can be blown into the person's cleaning area or onto the surface of the belt in the cleaning area and this must be provided as at least one which also acts as an acid dipping or cleaning medium Additional media and suitable sources as well as pipes and dosing devices are present in another phase. For example, one such system is disclosed in the manufacture of European Patent No. 7,007,668 ... [Summary of the Invention] Therefore, the object of the present invention is to improve the above-mentioned method and device, in this way 86815 200422436 appears in its device _ 0i m π, available devices and control devices that can be attacked, and use already existing in the device Avoid the formation of spots on the treated material. To achieve this goal, this feature is characterized by the acid leaching of the medium being applied to the surface of the material at least in this area when the belt pauses. This maintains the quality of the treated material even after the deflection is brought out, while still avoiding overflow of the material in the cleaning area. The formed spots were effectively removed when the acid was re-soaked. Double It is an advantage if the surface of the material wetted by the acid-soaked vehicle is sprayed again with the cleaning medium. According to the first preferred embodiment of the device, the belt is moved back into the acid pickling area in the direction opposite to the direction of transportation in normal operation, and returned to the proper place. The wetted area of the acid leaching vehicle is taken to the cleaning area again. Therefore, no additional components are required in the cleaning area. Whether it is additional or as an optional example, the belt can be reversed into the zone: or: the belt can also be spray-washed with an acid dipping medium, if it is so booked, it is better to enter the acid dipping in its reverse direction Before the area. The μ car also blamed the belt for spray cleaning with leaching medium when π was at a standstill. According to local knowledge, the device in the first specific embodiment is characterized in that a program is included in the device =: =. This program allows the belt to automatically enter the acid leaching area in the opposite direction after the pause, and then makes the operator 2 3Γ: To normal operation, and restructure the area where the acid leaching vehicle has been applied again to the cleaning area. No closure is made in this particular embodiment, but only the control system is changed or re-planned. 86815 200422436 However, in a specific embodiment where 'with only minor structural changes and also nozzles or sprinklers are connected to the acid leaching medium', the selective feeding of the cleaning or cleaning medium, there is no need to change the control body. The side device can be extended so that the spray medium has a feed tube and has an acid valve fitting. In the system according to the present invention, in order to process different belt guides, the same manner and the same effect can be achieved. In addition to the nozzle or sprayer for cleaning the media, the present invention can better predict the sprayer for pickling the media in the cleaning area. . / [Embodiment] In the description of "The Next Step", an example of a specific embodiment of the present invention will be described in more detail with an additional schematic diagram. The diagram shown in the drawings contains a schematic side view of part of a device according to the invention. In the normal direction of the material to be treated, the cleaning zone 2 is provided downstream in the acid pickling tank i or the like filled with the acid pickling medium. In the cleaning area 2, there are several sprayers 4 'through which the cleaning medium can be applied to the material M. The squeeze roller 5 is provided at the entrance of the pickling tank 1 and the exit of the cleaning area. If the belt M is stopped for several minutes, For example, due to the operation of the device, spots formed on part of the belt, which is common in the cleaning area 2. In order to remove these spots again and thus ensure the high quality of the processed material, the existing sprinkler 4 can be passed Or additional sprayers or nozzles (not shown) spray the belt M with the acid leaching medium again 'and / or cause the material M to travel a certain distance in the opposite direction to normal operation until the spots are in the acid leaching tank. The acid leaching medium disappears again. Any official immersion medium brought out of the acid leaching tank i by the belt M (although the squeeze roller 5 is provided at the tank entrance) is collected in the acid leaching tank and collected in the low plate. The stoppage stopped for another 86815 200422436 times until the spots had disappeared, or the material could be immediately transported again in the normal operating direction.
