In liquid bearing block 041；The side of feed liquor bearing block 041 is additionally provided with overflow port 049 simultaneously；Wherein feed liquor bearing block 041 passes through
Shaft 0410 is mounted on 05 lower part of rack.
The structure of rotary drum 03 is as shown in figure 3, include rotary drum 031, rotary drum 031 is internally provided with three fins 035, rotary drum
The top of cylinder 031 is provided with liquid outlet 032, and the bottom of rotary drum 032 is provided with lower shaft lid 033, and 033 bottom of lower shaft lid is provided with
Axle sleeve 036, pressure cap 037, lower shaft lid 033 and 031 bottom of rotary drum are provided with gasket 034.
036 relative motion of axle sleeve of sliding bearing 042 and 033 lower part of lower shaft lid, feed nozzle 045 are inserted into lower shaft lid
In 033, and there is relatively large gap between 033 inner wall of 045 outside wall surface of feed nozzle and lower shaft lid, to guarantee at work
It will not scratch.
When 03 rotation work of rotary drum, as shown in Fig. 4 (1), material to be separated passes through feed pipe 046, feed nozzle
045, lower shaft lid 033 enters rotary drum 03；Motor 01 drives 03 high-speed rotation of rotary drum by gear 02, in the work of centrifugal force field
Under, material is since the difference of component part density will do it layering or precipitating, and the clarified solution of innermost layer is by 03 top of rotary drum
Liquid outlet outflow, solid phase A are then deposited in consolidating in addition to sedimentation in 03 inner wall of rotary drum, manual cleaning after need to shutting down, while rotary drum 03
Except phase A, some liquid phase B.After rotary drum 03 stops operating, as shown in Fig. 4 (2), it is retained in this inside rotary drum 03
Partial Liquid Phase B can be by the gap between lower shaft lid 033 and feed liquor nozzle 045 via the overflow port of 041 side of feed liquor bearing block
049 outflow, since this partial material can be mixed during outflow with the lubricating grease C of drippage, the outflow of this part
Material has been contaminated, although the processing such as can be filtered, but be still can not handle completely it is clean, thus cause it is some not
Evitable loss.
