Sludge removal device and magnetic filter

The utility model relates to a sludge removal device and a magnetic filter, belongs to the technical field of cleaning devices, and solves the technical problem that similar equipment such as the conventional magnetic filter is relatively low in sludge removal and scraping efficiency. The sludge removal device comprises a support, a base and a shifting piece used for scraping sludge on a scraper, the shifting piece is connected to the support, the support is connected to the base, and by means of the sludge removal device, the sludge on the scraper of similar equipment such as a magnetic filter can be scraped, so that the sludge is prevented from being adhered to the scraper, and the sludge removal efficiency is improved. Further, the sludge is prevented from being adsorbed on the magnetic bar which is just scraped, so that the sludge scraping efficiency of similar equipment such as a magnetic filter is improved; the magnetic filter comprises a body and a sludge removal device, the body comprises a scraper, a
