Also be provided with axle bush between described lower cover and the rotary sleeve.
Also be set with the sleeve nut on the lower end of described rotary sleeve, the sleeve nut is connected with the protective sleeve that is sleeved on scraper screw mandrel bottom.
Further technical problem to be solved in the utility model is: a kind of slewing area that limits scraper is provided, prevents the scraper in its filter bag type centrifuge that scratches filter bag.
For solving above-mentioned further technical problem, the technical solution adopted in the utility model is: described supported box is provided with loam cake, described scraper screw mandrel is located in the loam cake, the top of scraper screw mandrel is provided with limited block, be provided with the forward and reverse spacing collar that is used to limit scraper screw mandrel slewing area in the loam cake, also be equipped with the set lever that is used for the lock adjustment screw mandrel in the loam cake.
The beneficial effects of the utility model are: super-magnum centrifuge is when discharging, can use will harden most of material on filter bag of scraper described in the utility model to scrape and fall, significantly reduced the bulk density of material, and then with suspender material is hung and to draw off bowl, thereby avoided hanging by force and drawn the damage that filter bag is caused, the service life of having improved filter bag effectively.In addition, by the slewing area that forward and reverse spacing collar limits the scraper screw mandrel is set, making has enough safety clearances between the scraper that is arranged on scraper screw mandrel bottom and the filter bag, thereby has avoided the accidental injury of scraper to filter bag.
