A vertical sedimentation type scraper discharge centrifuge

Abstract

The invention discloses a vertical settling scraping centrifuge. Operating steps include 1, before feeding, starting a cylinder to drive a lifting shaft which drives a closure cover to move so as to close an inner hole arranged in the lower small end of a drum, and allowing a main motor to drive a spindle driven pulley so as to drive the drum and the closure cover to rotate; 2, during feeding, adding mixture into the drum, allowing solid-liquid separation under the action of centrifugal force, and allowing liquid to be sucked out; 3, allowing scraping, to be specific, decreasing the speed of the drum so that the drum rotates at low speed, starting a scraper cylinder, and allowing a scraper to scrap solid from the wall of the drum to the bottom of the drum; 4, allowing pulping; 5, after pulping, raising stirring paddles and the scraper, allowing rise of the speed, allowing secondary solid-liquid separation, and allowing the liquid to be sucked out through a skimmer tube; 6, allowing discharging. The vertical settling scraping centrifuge is simple in structure, has the functions such as separating, pulping and discharging, is convenient to operate, has a shorter process and a tight process route and is higher in productivity.

Description

technical field [0001] The invention belongs to the field of centrifuges, and in particular relates to a vertical sedimentation type scraper discharge centrifuge. Background technique [0002] Centrifuge is a kind of equipment widely used in chemical, pharmaceutical and other industries for solid-liquid separation. In many processes, it is necessary to fully stir and mix the materials scraped by the centrifuge for the first time with a solvent, and then separate them for the second time after washing. . Under normal circumstances, after being separated by the scraper discharge centrifuge, the material scraped by the scraper is discharged from the discharge hole at the bottom of the drum and needs to enter another tank for beating. After the beating is completed, it enters the centrifuge for separation. There are many demands, the process route is long, the process is many, and the input cost is high. Contents of the invention [0003] The object of the present invention ...

Problems solved by technology

Under normal circumstances, after being separated by the scraper discharge centrifuge, the material scraped by the scraper is discharged from the discharge hole at the bottom of the drum and needs to enter another tank for beating. After the beating is completed, it enters the centrifuge for separation. More demand, long process route, many processes, high input cost
