This utility model discloses a
sedimentation and separation device for the main
hydrolysate of
plant fiber raw materials, belonging to the field of
sedimentation and
separation technology. It includes a
sedimentation tank with a mounting bracket fixed inside, and a
drive motor mounted on the bracket. A rotating shaft is connected to the lower end of the
drive motor, and the rotating shaft is located inside the sedimentation tank. Through a preliminary
filtration structure, in conjunction with a reduction motor and a
cam, the device performs preliminary
filtration using a filter screen. Simultaneously, the reduction motor drives the
cam to rotate, intermittently striking the connecting frame. This causes the
fixed frame to vibrate via a vibration spring, preventing impurities from adhering to the filter screen and causing blockage. A supernatant extraction structure is employed, utilizing a multi-stage
telescopic cylinder to adjust the height of the lifting plate and the extraction
pipe. This allows the height of the extraction
pipe's suction end to be adjusted according to the supernatant level and the thickness of the settled
sludge, ensuring effective supernatant extraction while avoiding the extraction of
sludge.
