Abstract

The invention discloses an automatic lowering and unloading centrifuge, comprising a barrel and a base, the barrel is mounted on the outer wall of the upper end of the base, an organic cover is arranged on the outer wall of the upper end of the barrel, and the outer wall of the upper end of the cover is provided with a Working motor, a cylinder is set on the cover on the left side of the working motor. When the cylinder is used for scraping, the piston rod pushes the knife base to move down together, and the scraper scrapes the filter cake on the screen. At the same time, there is a knife on the scraper. This makes it easier for the material to pass through the knife hole, the vortex formed on the drum is less damaged, and the centrifugal efficiency is also slightly reduced, which is difficult to affect the overall centrifugal effect. In the silo, it sometimes accumulates on the rotating disk and the fixed frame, so that the waste residue is blown down in the air inlet pipe, so as to avoid the accumulation of the waste residue, which affects the collection of the waste residue.
