  • High-pressure water jet sheet strip sand-blasting descaling cleaning device, cleaning line and system
    Patent number: 12275118
    Abstract: A high-pressure water jet sheet strip sand-blasting descaling cleaning device, a cleaning line and a system are disclosed. The cleaning device includes a cleaning box (7), a washing box (18) and descaling nozzles (6), the descaling nozzles (6) face to the same width direction of a sheet strip (5) and are arranged in a gradient along a conveying direction of the cleaning box (7) to jet covering the sheet strip (5). The system includes the cleaning device, an abrasive collecting box, a high-pressure water supply system, an abrasive supply-recovery-separation system and a sewage recycling treatment system. The nozzles are slantwise arranged in a gradient along the conveying direction, and the neighboring nozzles do not interfere with each other, and are used for cleaning successively, so that a cleaning process is stable and controllable.
