Description
The utility model relates to a kind of centrifugal dehydrator of industrial usefulness, particularly liquid-solid mixture is concentrated and filters the outside filtering type centrifugal dehydrator of usefulness.
At present in industrial production, to the employed centrifugal dehydrator of the dehydration of liquid-solid mixture, its common characteristic is the sedimentation of material and filters and all carry out in same rotating cylinder, sediment and filter residue all concentrate at the inwall of rotating cylinder, with shedding mechanism it is taken out then, thereby, caused the complicated of centrifugal dehydrator, in addition, its another common characteristic is that the moisture content in the material all throws away by filter cake layer and the eyelet thereof that is deposited on the drum wall, because its filter cake layer directly is subjected to the influence of feed concentration, filter cloth can't clean in addition, make centrifugal dehydrator not only to the strictness of feed concentration requirement, and its filter effect and production capacity also is very restricted, thereby causes existing centrifugal dehydrator to fail to be widely used always.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and provide a kind of will concentrating separately to carry out with filtration operation, promptly in rotating cylinder, carry out earlier the dehydration first time---concentrate, the filter that then concentrate is caused the rotating cylinder outer rim carries out dehydration---the centrifugal dehydrator of filtration for the second time.
The utility model is achieved by the following scheme: in the outer rim of double-deck truncated cone rotating cylinder, be equiped with four filters that rotate with rotating cylinder, after material after the process rotating cylinder concentrates borrows centrifugal force to enter filter, filter by predetermined filter cycle, filter residue is then delivered to sludge outlet by the blade in the filter.
The advantage that the utlity model has is: the deposition of solid amount in the rotating cylinder is significantly reduced, thereby alleviated the rotary inertia of rotating cylinder, reduced the water content that enters filtration operation, thereby improved filter capacity and filtrate water quality, the dewatering efficiency height, equipment use, easy to maintenance.
