Abstract
The utility model discloses a conical hydraulic classifier. The conical hydraulic classifier comprises a groove and a central feeding barrel which is arranged in the axial middle of the groove and provided with a tangential feeding tube. A conical shield plate with a downward opening is arranged on the central feeding barrel and on the lower portion of the feeding tube, and a helical component is arranged at the bottom of the central feeding barrel and comprises a helical blade. The helical blade is mainly provided with two functions, one is to accelerate sedimentation of ore pulp, and the other is to slowly stir the ore pulp subsided to the bottom, provide fine and light ore particles mingled with the ore pulp at the bottom with a chance to ascend again so as to enable the particles to be discharged through classified overflow from an overflow groove arranged on the upper portion of the groove. Large particles in the ore pulp are discharged from a discharge tube at the bottom of the groove, and the conical shield plate can prevent coarse particles ascended again from getting out through overflow. The conical hydraulic classifier has the advantages of being capable of separating the large particles from the fine and light particles in the pulp well, good in classifying effect, high in efficiency and environment friendly.
Description
Technical field
The utility model relates to a kind of circular cone hydraulic classifier.
Background technology
Cone classifier is made into closed cycle journey branch journey shunting ore deposit sand with ball mill in the ore dressing plant; Or be used in and come classification ore in sand form and thin mud in the gravity mill; And in the metal beneficiation flowsheet ore pulp is carried out grading, and operations such as desliming, dehydration in the washup operation.Present cone classifier is the gravity down sedimentation naturally that utilizes ore pulp, complex structure, and classification efficiency is low.
The utility model content
The purpose of the utility model is to provide a kind of classification efficiency high, simple in structure circular cone hydraulic classifier.
This circular cone hydraulic classifier that the utility model provides; Comprise that cell body, center are to barrel; The center is positioned at the axial centre of cell body to barrel; The feed pipe that the tangential is arranged on it, said center on the barrel, there is downward opening conical cover plate the below of feed pipe, there is screw assembly at said center for the bottom of barrel.
The epimere of said cell body is circular cylindrical shell, and the cylindrical shell lower end is lower than the bottom of said conical cover plate, near the port place overflow launder is arranged on the cylindrical shell, and the cylindrical shell lower end connects up big and down small taper shape bucket, and the bottom of conical bucket connects drainage conduit.
Said screw assembly comprises central shaft and fixing helical blade on it, and the profile of helical blade is up big and down small taper shape.
The utility model can make thin, the light grains in the ore pulp from the overflow launder on cell body top, discharge, and coarse granule is discharged from the bottom discharging pipe of the conical bucket of cell body, and grading effect is good, efficient is high, thereby reaches the purpose of energy-conserving and environment-protective.The central feeding drum outer wall of its structure has conical cover plate, bottom that the tapered auger blade is arranged, and helical blade mainly contains two effects, and the first is quickened the sedimentation of ore pulp; It two is that the ore pulp that is deposited to the bottom is slowly stirred, and gives the chance of thin, the light ore particle be mixed in the ore pulp of bottom to rise once again, make their from cell body top the classification overflow discharge.Conical cover plate can prevent that the coarse granule that rises once more from running out of through overflow.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the schematic top plan view of Fig. 1.
The specific embodiment
Like Fig. 1, shown in Figure 2, this circular cone hydraulic classifier that the utility model provides comprises that cell body 1, center are to barrel 2, power transmission shaft 3, fixed mount 4, conical cover plate 5.Power transmission shaft 3 is connected in the upper end that barrel 2 is given at the center, and the center is fixed in the centre of fixed mount 4 for barrel 2, and fixed mount 4 is fixed on the port of cell body 1, and cell body 1 is fixed on the bracing frame 9.The epimere of cell body 1 is circular cylindrical shell 11, and the lower end of cylindrical shell 11 is lower than the bottom of conical cover plate 5, near the port place overflow launder 6 is arranged on the cylindrical shell 11, and cylindrical shell 11 lower ends connect up big and down small taper shape bucket 12, and the bottom of conical bucket 12 connects drainage conduit 7.The axial centre that the center is positioned at cell body 1 for barrel 2 has the feed pipe 21 of tangential, downward opening conical cover plate 5 to be positioned at that the center is given on the barrel 2, the below of feed pipe 21 on it.It is screw assembly 8 that the bottom of barrel 2 is given at the center, and screw assembly 8 comprises central shaft 81 and fixing helical blade 82 on it, and the profile of helical blade 82 is up big and down small taper shape.
The operation principle of the utility model is following: transmission device drives power transmission shaft 3 and rotates, and power transmission shaft 3 drive centers rotate for barrel 2, thereby the drive center stirs ore pulp for the helical blade 82 of barrel 2 lower ends.Ore pulp gets into wherein for along the center tangential direction of barrel 2 through feed pipe 21, descends in a spiral manner, flows to the taper shape bucket 12 of cell body 1 along helical blade 82 from the bottom of center feed tube 2.When ore pulp flow to the bottom of conical bucket 12, meet with its cone wall, the part coarse granule is deposited to its bottom, and the part ore pulp becomes rising ore deposit stream under the reaction force of cone wall.The stirring of the ore pulp of helical blade gives to be mixed in the chance of thin, light ore particle to rise once again in the ore pulp of bottom.In uphill process; Wherein have the part ore pulp in uphill process, to meet with conical cover plate 5, wherein thin, light ore particle passes through from the annulus that conical cover plate 5 and cell body 1 top cylindrical shell 11 surround under the effect of ascending current; Coarse granule is fallen the bottom; Discharged by drainage conduit 7, thin, the light ore particle of rising is discharged through overflow launder 6 as the classification overflow.
