technical field

The invention belongs to the technical field of scraper centrifuges, in particular to a crystal material damage protection type scraper centrifuge.

Background technique

The main motor of the scraper unloading centrifuge drives the inner and outer drums of the set to rotate at full speed. The material is introduced into the drum through the feed pipe. In the gap between the inner and outer drums, the through hole to the siphon chamber enters the siphon chamber, and then is sucked out by the siphon device and discharged out of the machine. The solid phase is trapped in the inner drum to form an annular filter cake layer. After the feed reaches the predetermined volume Stop feeding and further separate. At this time, washing can be carried out. After washing and separation, the scraper will automatically rotate, and the solid phase will be scraped off and discharged out of the machine through the conveying screw, and then the net will be automatically washed to start the next cycle; the application number is 201811125370.2 The invention discloses a fully automatic vertical scraper centrifuge, which adopts the combination of a storage frame with a first through hole, a baffle with a second through hole, and a motor.
