The invention relates to a self-compensating sludge scraper, in particular to an automatic scraper device used for cold rolling emulsified liquid magnetic filters, and belongs to the technical field of steel rolling machinery. The self-compensating sludge scraper comprises a fixed connecting plate used for installing the scraper. The lower end of the scraper is provided with semicircular notches matched with to-be-wiped magnetic bars. The fixed connecting plate is provided with a horizontal plate extending downwards out of a front clamping plate and a back clamping plate. A clamping block is arranged between the front clamping plate and the back clamping plate, and the clamping block, the front clamping plate and the back clamping plate form a vertically-moving pair. The clamping block is provided with a vertical surface and a horizontal surface. The vertical surface is fixed with the scraper. A group of vertical springs distributed at intervals are arranged between the horizontal surface and the horizontal plate of the fixed connecting plate. With the function of the springs, the scraper can be tightly attached to the magnetic bars all the time in the process of wiping, abrasion can be automatically compensated, and good wiping effects can be maintained for a long time.
