Planetary roller type plate strip scale breaking device

Abstract

The invention relates to the field of metal plate strip production, in particular to a planetary roller type plate strip scale breaking device. The device is characterized in that the device comprises a rack, a base, a first tension roller, a second tension roller and cleaning rollers; the first tension roller and the second tension roller are arranged in the rack in parallel and connected with a tension roller motor through a tension roller speed reducer, and a metal plate strip forms a zigzag route along the surfaces of the first tension roller and the second tension roller; the cleaning rollers are distributed on the outer sides of the wrap angle arc sections of the first tension roller and / or the second tension roller in a planetary mode, the two ends of each cleaning roller are connected with the rack through bearing blocks, the bearing blocks are connected with the rack through screw adjusting mechanisms, and one end of each cleaning roller is sequentially connected with a coupler, a speed reducer and a cleaning roller motor. The device has the advantages that (1) the oxide layer on the surface of the metal plate strip is effectively removed through application of the combination of pulling, pressing and shearing stress on the oxide layer on the surface of the metal plate strip, and (2) waste liquid discharge and pollution are reduced.

Description

technical field [0001] The invention relates to the production field of metal strips, in particular to a planetary roller scale breaking device for strips. Background technique [0002] The surface descaling technology of metal strips (that is, the removal of surface oxide layer) is an indispensable process before finishing. The quality of surface cleaning will directly affect the quality of the metal surface and the surface quality of subsequent processed products. The traditional surface treatment of metal strips is mainly pickling, but the pickling process will inevitably bring some pollution to the environment. In order to adapt to the global environment and sustainable development issues, the metal manufacturing industry should adopt a more environmentally friendly green production process . Greening is a major trend in future metal industry production, so it is necessary to provide a device that can eliminate or reduce acid discharge, replace or partially replace chem...
