Description
Technical field
The utility model relates to field of sludge treatment, especially relates to a kind of centrifuge blade construction.
Background technology
In the preliminary hydro-extraction process of Treatment of Sludge, be generally by centrifuge, to reduce the water content of mud.When mud is sent in the central tube of centrifuge by feed pipe, by mud, the charging aperture from central tube throws away and enters into rotary drum the high speed rotating of central tube, under centrifugal action, the solid formation that density is larger is deposited on and on rotatory drum wall, forms sediment layer, and the less liquid phase thing of density is stayed internal layer.Solid formation is discharged through slag notch along with blade is pushed to centrifuge small end, and liquid phase thing is discharged from the leakage fluid dram of the large end of centrifuge, thus so constantly work reach continuous separate from object.Yet centrifuge blade construction of the prior art, isolated liquid phase thing is difficult for discharging from leakage fluid dram, and liquid phase thing is easily piled up, and greatly has influence on the separating effect of solid phase, liquid phase.
Utility model content
The utility model is in order to overcome above-mentioned deficiency of the prior art, provides a kind of liquid phase thing of being convenient to after separation to discharge smoothly, guarantee the centrifuge blade construction of separating effect.
To achieve these goals, the utility model is by the following technical solutions:
A kind of centrifuge blade construction of the present utility model, comprise central tube and twist, around the axial arranged blade of central tube, described blade comprises straight spiral section and cone spiral section, interior all diameters of straight spiral section are greater than central tube outer surface diameter, between the interior week of straight spiral section and central tube outer surface, be provided with some support columns, between adjacent support column, form through hole, the interior week of described cone spiral section and the laminating of central tube outer surface, the tube wall of described central tube is provided with charging aperture at the intersection of straight spiral section and cone spiral section.Its interior week of the blade at straight spiral section place forms for the moving passage of liquid phase stream between blade and central tube outer surface away from central tube outer surface.Central tube drives blade synchronization to rotate while rotating, the solid formation that is positioned at outside after blade promotion centrifugal action is carried to cone spiral section, and now liquid phase thing is positioned at the inner side near central tube, and the direction of motion of liquid phase thing is contrary with solid formation.Between the blade at straight spiral section place and central tube, by support column, be connected and fixed, can avoid the direction of motion towards solid formation by liquid phase thing to promote, thereby be convenient to liquid phase thing to discharge smoothly, so also make solid phase, liquid phase separation effect better, the moisture content of mud significantly declines.
As preferably, 1/3rd to 1/2nd of the length that the radial width of described cone spiral section place blade is support column.Leave so the moving space of liquid phase stream for relatively large, assurance liquid phase thing can be discharged in time.The resistance that solid formation is subject to while outwards moved by centrifugal force is also less, is more easily thrown to outermost, prevents that it from occurring to pile up and making blade wear serious at root of blade, has also reduced the working (finishing) area of blade simultaneously, is conducive to reduce material and processing cost.
As preferably, it is upper that described support column is evenly distributed in straight spiral section week, and support column is along the radial arrangement in week in straight spiral section.Vane stress is comparatively even like this, less for the impact of support column when in mud, solid formation moves laterally under centrifugal action, contributes to guarantee leaf longevity.
As preferably, the interval angle that described support column is adjacent between support column is not less than 20 degree.Improve like this interval angle between support column, can further reduce the resistance that support column produces for liquid flow, liquid phase thing more easily flows to leakage fluid dram.
As preferably, the cross section of described support column is rounded.
Therefore, the utlity model has following beneficial effect: (1) has reduced the flow resistance of liquid phase thing, improved liquid phase thing and discharged ability; (2) liquid phase in mud, solid phase separating effect are better, effectively reduce the water content in mud; (3) solid formation is difficult for piling up, and reduces the wearing and tearing of blade.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the side view of straight spiral section in the utility model.
In figure, blade 1, cone spiral section 1a, straight spiral section 1b, through hole 101, support column 2, charging aperture 3, central tube 4.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
In embodiment as shown in Figure 1, a kind of centrifuge blade construction, comprises central tube 4 and blade 1, and blade 1 twist, and axial arranged around central tube 4.In the present embodiment, blade 1 is dextrorotation, comprise straight spiral section 1b and cone spiral section 1a, wherein interior all diameters of straight spiral section 1b are greater than central tube 4 outer surface diameter, between the interior week of straight spiral section 1b and central tube 4 outer surfaces, be provided with some support columns 2, support column 2 two ends are welded and fixed with interior week and central tube 4 outer surfaces of straight spiral section 1b respectively.The interior week of cone spiral section 1a and central tube 4 outer surface laminatings, the tube wall of central tube 4 is provided with charging aperture 3 at the intersection of straight spiral section 1b and cone spiral section 1a.
As shown in Figure 2, it is upper that support column 2 is evenly distributed in straight spiral section 1b week, and support column 2 is along the radial arrangement in week in straight spiral section 1b, in the present embodiment, within the scope of single pitch, have 14 support columns, the cross section of support column is rounded, to reduce the moving resistance of liquid phase stream.Between adjacent support column, form through hole 101, the projection of through hole 101 on central tube 4 cross sections is fan-shaped.The radial width of cone spiral section place blade is 1/2nd of support column length.
In actual moving process, mud is sent to central tube 4 inside, and central tube 4 high speed rotating, outwards throw away mud from charging aperture 3, and liquid phase thing is positioned at the inner side near central tube 4, and the direction of motion of liquid phase thing is contrary with solid formation, and liquid phase, solid phase start separation.When rotating, central tube 4 is with moving vane 1 also to rotate simultaneously, solid formation is carried to cone spiral section 1a, liquid phase thing flows between the blade at straight spiral section 1b place and central tube 4 again, thereby easily liquid phase thing is discharged, solid phase, liquid phase in mud complete separation, and the moisture content of mud declines.
