Description
Technical field
The utility model relates to solid-liquid separation technique, and concrete is a kind of centrifugal separator for solid from liquid.
Background technology
Along with growth in the living standard, people more and more pay attention to environmental protection.Wastewater treatment is to embody a particularly important link of environmental issue, and therefore centrifugal equipment for separating liquid from solid is more and more extensive in field ranges of application such as environmental protection, municipal wastewater processing.Mud is sent in the cavity of outer tube by screw conveyor shaft after, under the centrifugal action that High Rotation Speed produces, because mud granule proportion is larger, thereby the centrifugal force that produces is also larger, is got rid of on the inwall that is attached to outer tube, the formation solid layer; Water density is little, and centrifugal force is also little, only at the inboard liquid level that produces of solid layer.The mud of solid layer is transported to the cone end of outer tube under the slow promotion of the helical blade on screw conveyor shaft, discharge continuously through the solid phase outlet, and liquid drains into outside outer tube from the overfall that outer tunnel end covers.
At present, most centrifugal separator for solid from liquids are conical apart from the outer tube of the solid phase port of export, and under larger centrifugal action, conical outer tube small end produces because contact area is little and rocks, and is firm not.Secondly, the volume of screw conveyor shaft is large, causes the volume in outer tube to diminish, and the sludge quantity of processing is less.Its three, helical blade is unfavorable for effective Separation of Solid and Liquid for being equally spaced.Its four, the outlet of existing solid phase is for radially arranging, and the solid phase outlet be arranged on conical outer tube small end than the top, the solid phase amount of disposable like this eliminating is less, is unfavorable for the solid phase eliminating.
The utility model content
Main purpose of the present utility model is to overcome deficiency of the prior art, provides that a kind of simple in structure, volume is large, the better centrifugal separator for solid from liquid of solid-liquid separation effect.
above-mentioned technical problem of the present utility model is implemented by the following technical programs: a kind of centrifugal separator for solid from liquid, comprise outer tube, be placed in the screw in outer tube, the liquid-phase outlet device on the solid phase outlet device of screw end and screw top, described screw comprises screw conveyor shaft, the helical blade that arranges on screw conveyor shaft, be provided with several flow spoilers on described screw conveyor shaft, described solid phase outlet device comprises solid phase mud mouth and secondary solid phase mud mouth, a described solid phase mud mouth axially arranges along screw conveyor shaft, the helical feed the tip of the axis is provided with mudflap, described secondary solid phase mud mouth is arranged between mudflap and solid phase mud mouth, secondary solid phase mud mouth is horizontally disposed with and is communicated with a solid phase mud mouth, described helical blade pitch is extracted the district by the helical blade settling section to the helical blade conveying and is increased gradually.Because centrifuge is less near the centrifugal force at screw conveyor shaft place, centrifugal force is larger more outward, sets up flow spoiler solidliquid mixture is pressed against on the inwall of outer tube as much as possible, increases centrifugal force to improve solid-liquid separation efficiency.Due to the action of gravitation of solid formation itself, add the axial setting of last solid phase mud mouth, can make solid formation quick and smooth enter secondary solid phase mud mouth place.Secondary solid phase mud mouth plays the effect of guiding.More near the solid phase discharge end, material is got over thickness to solidliquid mixture, increases helical blade pitch, is conducive to solid formation and moves to mud mouth.
