Abstract
The invention belongs to the field of mechanical equipment, and relates to a continuous slurry supply system and a use method. For the steel plate surface treatment, a special slurry supply system is designed, i.e., slurry is alternately supplied by utilizing two groups of specially designed slurry supply devices, so that the continuous supply of slurry is realized, and the continuity of strip steel surface treatment is ensured. The traditional premixed pumping type jet system is only equipped with a feed cylinder, and the feed cylinder needs to be re-washed after the slurry is supplied to the outside, thus the continuous production cannot be realized, and pistons are seriously worn. The slurry supply device provided by the invention is internally provided with a wear-resistant and corrosion-resistant bellows mechanism capable of extending and retracting in a wide range, so that the slurry is alternately suctioned and fed by the two groups of slurry supply devices through the periodic extending and retracting of the bellows mechanism, i.e., the slurry is suctioned from a stirring box by one slurry supply cylinder, and simultaneously the other slurry supply cylinder feeds the slurry to an injection nozzle carrier, and the work modes of the two cylinders are exchanged after the slurry suction and feeding are synchronously completed. Accordingly, the continuous supply of mixed slurry can be realized, and a condition is created for the continuous treatment of the surface of strip steel. The slurry used by the invention is a mixture of water and an abrasive which can be recycled, and is environment-friendly, and the zero emission of waste and harmful substances is realized.
