Description
Technical field
The utility model relates to solid-liquid separation technique field, is specifically related to a kind of filtration system of collecting solid ore particle from dilute phase fine mineral suspension.
Background technology
In fields such as chemical industry metallurgicals, usually need to carry out Separation of Solid and Liquid operation.In theory, the suspension of solid particle material is that the liquid filtration liquid that former water can obtain clarification through Separation of Solid and Liquid operations such as plate-frame filtering, belt vacuum filtration, centrifugation filtrations is clear water; But in actual production process particularly in mineral process, because the upstream of Separation of Solid and Liquid operates as the needs of the process conditions such as Chemical Leaching, flotation sort, mineral grain is often crushed to ultra-fine micron order granularity, in the time that micron order solid mineral is carried out to Separation of Solid and Liquid, we find, it is still muddy suspension that the suspension of fine grained mineral, the suspension of large or fine granule mineral intermixture material operate through above-mentioned conventional Separation of Solid and Liquid the clear water obtaining, and this muddiness suspension feature is: solid phase rare (being that solid ore particle concentration in liquid phase is little), suspension ore particle fine size.Research is found: the aperture of the filter cloth of plate and frame filter press, vacuum filter or filter centrifugal is generally at tens microns (approximately 300 ~ 400 orders), be applicable to the separation of large concentration and coarsegrain mineral suspensions, and the particle diameter of fine grained ore particle in mineral suspensions is in the time of several microns even thinner, in filter operation, fine grained ore particle can see through filter cloth and enter clear water, due to these fine grained ore particle fine sizes, surface can be large, be difficult to sedimentation, thereby be suspended in liquid phase clear water, become muddy dilute phase fine mineral suspension, occur the problem of " clear water is unclear "! The ultra-fine brightness molybdenum concntrate of the dilute phase suspension producing in molybdenum bisuphide production process belong to this situation.
