Description
Technical field
The utility model relates to the solid-liquid separating equipment of fine Tailings Slurry, relates in particular to a kind of pillar Hhigh-efficient thickener.
Background technology
If the solid-liquid separating equipment of thickening machine main based on gravitational settling effect, it can be by the ore pulp of low concentration (10%-20%) by the underflow ore pulp of gravitational settling simmer down to high concentration (30%-50%), discharged by concentrator bottom, and concentrator top produces the clarified solution (overflow) of clarification, discharged by top.
But existing concentrator is the cylindrical shape shallow slot at a band cone end, is provided with overfall on the sidewall of groove top, is provided with discharging opening at trench bottom; For the underflow ore pulp that makes high concentration is discharged smoothly, generally in concentrator bottom, harrow frame is installed, harrow frame drives microrunning in dense groove by the motor being located at outside groove, underflow is collected to center drainage conduit and discharges.The defect that the concentrator of this structure exists is: the one, and because diameter is generally all more than tens meters, and ratio of height to diameter is little, causes floor space large, and thickening efficiency is also low.The 2nd, the harrow frame arranging has increased accident potential; The 3rd, because needing motor, harrow frame drives, and operating cost is high.
Summary of the invention
In order to overcome the technological deficiency that existing concentrator floor space is large, thickening efficiency is low and separation costs is high, the utility model provides a kind of microfine mine tailing pillar Hhigh-efficient thickener of (general granularity is less than 0.074mm) that is applicable to processing.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of pillar Hhigh-efficient thickener, it is characterized in that, it is a hollow cylinder, described hollow cylinder is a reducing hollow cylinder, reducing hollow cylinder is called as settling section, changeover portion, column body segment and cone segments from top to bottom successively, settling section and column body segment are an isometrical cylinder, and changeover portion and cone segments are all isosceles inverted trapezoidal shapes; Being provided with bottom at the middle part of hollow cylinder opening part is trumpet-shaped to barrel, and the column body segment of stretching into hollow cylinder to barrel bottom, is provided with discharging cylinder in cone segments bottom; Require:
The diameter of column body segment is 5-10m, and ratio of height to diameter is greater than 2;
Settling section diameter is 1.2-2 times of column body segment diameter;
Discharging cylinder diameter is 0.2-0.25 times of column body segment diameter, and the height of discharging cylinder and equal diameters;
The conical surface of cone segments and the angle of horizontal direction are between 60 °-75 °;
The conical surface of changeover portion and the angle of horizontal direction are between 5 °-30 °.
When the utility model uses, concentration is that the mine tailing of 10%-35% is from feeding to barrel, rely on gravitational settling effect, concentrated in concentrator, thereby form respectively settling section, transition region, compressional zone at settling section, changeover portion and column body segment, the overflow of settling section is discharged from settling section overfall, can be used as ore dressing plant recirculated water and use, the high-concentration ore slurry of compressional zone is discharged from discharging cylinder, and the material concentration of discharging from discharging cylinder is at 40%-70%.
The beneficial effects of the utility model are:
1, the utility model is by the ingenious specifications parameter that each section of hollow cylinder is set, make slurry concentrated in concentrator according to the gravitational settling of self, because column body segment ratio of height to diameter is larger, increase the sedimentation time, give compressional zone enough pressure, and existing concentrator diameter is generally all more than tens meters, and ratio of height to diameter is little, so the utility model concentrated effect is better than prior art;
2, because the ratio of height to diameter of the column body segment of concentrator is greater than 2, make the volume small footprint size of equipment little;
3, because cone segments angle is larger, do not need harrow frame and the power-equipment just can be effectively anti-blocking, small investment, use cost is low.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Drawing explanation: 1-settling section, 2-column body segment, 3-cone segments, 4-discharging cylinder, 5-is to barrel, 6-changeover portion.
Angle [alpha] represents the conical surface of cone segments 3 and the angle of horizontal direction.
Angle beta represents that the conical surface of changeover portion 6 and the angle of horizontal direction are between 5 °-30 °.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, but be not restriction the utility model.
Pillar Hhigh-efficient thickener as shown in Figure 1, it is the hollow cylinder of a reducing, reducing hollow cylinder is called as settling section 1, changeover portion 6, column body segment 2 and cone segments 3 from top to bottom successively, settling section 1 and column body segment 2 are an isometrical cylinder, and changeover portion 6 and cone segments 3 are all isosceles inverted trapezoidal shapes; Being provided with bottom at the middle part of hollow cylinder opening part is trumpet-shaped to barrel 5, stretches into the column body segment 2 of hollow cylinder to barrel 5 bottoms, is provided with discharging cylinder 4 in cone segments 3 bottoms; Require:
The diameter of column body segment 2 is 5-10m, and ratio of height to diameter is greater than 2;
Settling section 1 diameter is 1.2-2 times of column body segment diameter;
Discharging cylinder 4 diameters are 0.2-0.25 times of column body segment 2 diameters, and the height of discharging cylinder 4 and equal diameters;
