Description
Technical field
The present invention relates to centrifugal extraction equipment field, particularly relate to a kind of centrifugal extractor rotary drum and above-mentioned Centrifugical extraction
The manufacture method of machine rotary drum.
Background technology
The work process of centrifugal extractor is broadly divided into two parts: i.e. mixes mass transport process and centrifugal separation processes, waits to mix
Close two kinds of immiscible liquid under centrifugal extractor rotary drum effect high speed rotating thus produce centrifugal force, at the work of centrifugal force
The liquid big by lower density is outwards assembled, and the liquid that density is little is inwardly assembled, and two kinds of liquid can gradually be layered and form a boundary
Face, the liquid that density in outside is bigger discharged by heavy phase channels, and the less liquid of density in inner side is by light phase passage
Discharge, thus complete separation process.
Conventional centrifugal extracter rotary drum uses upper and lower bearings at both ends to support, and the installation place of bottom end bearing is positioned at mixing liquid
Place, inevitably needs to consider the various problems such as the sealing of bottom end bearing, corrosion, and generally bottom end bearing uses machinery
Seal, but due to reasons such as drum body rotation and assembly precisions, the mechanical seal of bottom end bearing easily lost efficacy, and durability degree is the highest,
Ultimately result in the problems such as equipment leakage, and bottom end bearing causes it to keep in repair into its reason such as precision, sealing due to installation site
This height, affects industrial production efficiency.
Another centrifugal extractor rotary drum high speed rotating in the course of the work, the structure using upper and lower end bearing to install is necessary for
The strict axiality controlling upper and lower end bearing installation position, to avoid occurring causing centrifugal extractor to shake during running up
Move the problem violent, noise is big or concentrated wear is serious, also have drum body high-speed rotation exactly to also require that the dynamic balancing of bulging body must
Must carry out strict regulation, the highest to the requirement for dynamic balance of drum body, after traditional barrel tumbler completes, its dynamic balancing regulation is tired
Difficult.
