冷轧带钢真空清洁系统及其控制方法
摘要：
本发明公开了一种冷轧带钢真空清洁系统，包括真空泵、第一真空辊、第二真空辊、第一真空辊抽吸切断阀、第二真空辊抽吸切断阀、第一真空辊反冲洗切断阀、第二真空辊反冲洗切断阀、反冲洗过滤水切断阀以及反吹扫压缩空气切断阀，其中，第一真空辊抽吸切断阀位于第一真空辊和真空泵之间的管道上，第二真空辊抽吸切断阀位于第二真空辊和真空泵之间的管道上；反冲洗过滤水切断阀位于过滤水源与第一真空辊之间的管道上，反吹扫压缩空气切断阀位于压缩空气源与第一真空辊之间的管道上，反冲洗过滤水切断阀与第一真空辊之间的管道上安装有第一真空辊反冲洗切断阀。本冷轧带钢真空清洁系统，能连续对带钢表面进行清洁和除湿处理，同时减少了换辊次数。
摘要（英）：

The invention discloses a vacuum cleaning system for cold-rolling strip steel. The vacuum cleaning system comprises a vacuum pump, a first vacuum roller, a second vacuum roller, a first vacuum roller suction stop valve, a second vacuum roller suction stop valve, a first vacuum roller back-washing stop valve, a second vacuum roller back-washing stop valve, a back-washing filtered water stop valve and a converse-blowing compressed air stop valve. The first vacuum roller suction stop valve is located on a pipeline between the first vacuum roller and the vacuum pump. The second vacuum roller suction stop valve is located on a pipeline between the second vacuum roller and the vacuum pump. The back-washing filtered water stop valve is located on a pipeline between a filtered water source and the first vacuum roller. The converse-blowing compressed air stop valve is located on a pipeline between a compressed air source and the first vacuum roller. The first vacuum roller back-washing stop valve is installed on a pipeline between the back-washing filtered water stop valve and the first vacuum roller. The vacuum cleaning system for the cold-rolling strip steel can conduct cleaning and dehumidifying treatment on the surface of the strip steel continuously, and meanwhile the roller replacing frequency is reduced.
