Description
Technical field
The present invention relates to a kind of small-sized ultrahigh speed horizontal screw centrifuge, belong to the solid-liquid separating equipment technical field.
Background technology
Centrifuge is the separation equipment that a kind of centrifugal force that utilizes rotary drum to drive material rotation generation is strengthened separation process.Centrifugation is to utilize centrifugal force to process that liquid-solid, liquid-liquid-solid, liquid-non-homogeneous mixtures such as liquid separate.Its process is divided into centrifugal filtration, centrifugation and three kinds of forms of centrifugal sedimentation, and centrifuge correspondingly also is divided into filtering centrifuge, centrifugal separator and sedimentation centrifuge three major types.The purpose of separating is not outer is: reclaim valuable solid phase; Reclaim valuable liquid phase; Solid phase and liquid phase all reclaim; The solid-liquid two-phase is all drained.
Horizontal spiral discharging centrifuge, be the environmental protection industry equipment of current national encourage growth, is mainly used in the Separation of Solid and Liquid of urban industry waste water and sanitary sewage, thereby realize the harmless emission of sewage, recovery and reuse again.Decaner is to adopt centrifugal settling method to carry out the machine of suspended liquid, it is to contain the suspension of fine particle (particle diameter d >=5 μ m), through Separation of Solid and Liquid, make suspension become the liquid of relative clean, due to no filter-fabric and filter screen, the power consumption of specific yield is less, the single machine production ability is large, being applicable to factory maximizes and automatic central controlled requirement, there is no the operation cycle, operation continuously, continuous feeding and discharging, easy and simple to handle, the mother liquor solid content is few, clarity is high, compact conformation, floor space is little and be easy to the characteristics such as airtight, now be widely used in environmental protection, oil, chemical industry, metallurgical, the field such as medicine food and light industry.The decaner critical piece has rotary drum, auger conveyor, differential mechanism, overload protection arrangement and slag unloading device.Horizontal screw centrifuge is the density contrast that relies on the solid-liquid two-phase, and under the effect of centrifugal force, the sinking speed of accelerating solid phase particles realizes Separation of Solid and Liquid.Because the sedimentation of suspension, conveying and the dehydration of sediment all complete in rotary drum.
At present, the equipment for separating liquid from solid of fine particle solution has following: (1) disk centrifuge: can the Full automatic feed deslagging, but slag-draining device complexity, temporary transient not realization on small-sized machine, and can only process the material of solid content below 10%, it is larger that the rear material of processing contains liquid, uses usually used as concentrated.(2) tube centrifuge: can't realize automatic discharge, usually process the material of solid content below 5%, do clarification.(3) large scale industry horizontal screw centrifuge: domestic minimum model is diameter 200mm, rotating speed 5000r/min, separation factor 2750.Separation factor is low, inferior separating effect, and the machine energy consumption is large, and volume is large.Can't be used in laboratory and the small-sized industry that becomes more meticulous.Its primary structure comprises the casing cylinder of opposite opened, and two ends are the bearing block support structure independently, thus this kind structure because concentricity limit and can't accomplish high accuracy, so the rotating speed separation factor also can't be high again.During running, drive respectively rotary drum and spiral by small one and large one two motors, by differential mechanism, guarantee that rotary drum and spiral are with certain differential operation, material is entered in machine by charging aperture, through accelerating heavy falling on rotatory drum wall, because spiral and rotary drum have differential, by spiral, material is pushed into to the cone section dehydration of rotary drum, then discharges via discharging opening.Because of component limitations such as structure and differential mechanisms, can't accomplish miniaturization, separation factor is also lower.
Summary of the invention
