Scraper combined mechanism for centrifugal machine

Abstract

The invention discloses a scraper combined mechanism for a centrifugal machine. The scraper combined mechanism comprises a centrifugation cavity and a motor, the centrifugation cavity is provided with a rotating shaft, a scraper fixing disc is arranged at the lower end of the rotating shaft, and the bottom end of the rotating shaft is fixedly connected with a rotating shaft of the motor; scrapers are movably connected to the two sides of the upper end of the scraper fixing disc, the middle portions of the scrapers are movably connected with the lower ends of connecting rods, the upper ends of the connecting rods are movably connected with sleeves, and the sleeves are movably connected to the rotating shafts in a sleeving manner, and springs are wound around the rotating shafts; and a second bearing block is connected to the top end of each sleeve in a sleeving manner, and two push rods are fixedly connected to the two sides of the upper end of each second bearing block. By means of the structure, the rotating shafts are driven by the motor to rotate, and therefore the scraper fixing disc rotates to drive the scrapers to scrape materials; the controller is used for controlling a hydraulic push rods to drive the push rods to move vertically, and therefore the sleeves are driven to move vertically on the rotating shafts; and through the connecting rod structures, the scrapers are folded and unfolded, and therefore the distance between the scrapers and the material layer can be adjusted, and scraping of the different materials is achieved.

Description

technical field [0001] The technical field of the centrifuge scraper of the present invention is specifically a scraper combination mechanism for a centrifuge. Background technique [0002] The centrifuge is driven by the main motor to rotate the inner and outer drums at full speed. The material is introduced into the drum from the feeding pipe. In the gap between the drums, it passes through the through hole to the siphon chamber and enters the siphon chamber, and then is sucked out of the machine by the siphon device. The solid phase is trapped in the inner drum to form an annular filter cake layer. After the feed reaches the predetermined volume, the feed is stopped for further separation, and washing can be carried out at this time. After washing and separation, the scraper rotates automatically, and the solid phase is scraped off and discharged out of the machine through the conveying screw, and then the net is automatically washed to start the next cycle. The workin...

Problems solved by technology

[0003] This kind of scraper structure can only scrape materials for one kind of solid phase. When there are multiple solid phases with different densities in the material, it will form a layered filter cake structure with different thicknesses on the inner drum. A single scraper structure cannot hang and drop different materials, so we propose a scraper combination mechanism for centrifuges to solve the above problems
