The device can pass the mud through the scraper installed obliquely during the filtration process. The slurry is scraped to the mud outlet and discharged from the mud outlet, completing the automatic cleaning process and maintaining the permeability of the filter screen. The device has a simple mechanism and a compact structure, and can achieve continuous operation during use. The slurry is scraped out while working to maintain the permeability of the filter screen, thereby maintaining and improving the filtering effect and the production efficiency of the filter press. The problem that the existing filter press device has a complex structure, which occupies a large space, and during operation, it mostly works intermittently, with low production efficiency, and the filter residue and mud produced by the production will accumulate inside the device.
