Description
Technical field
The utility model relates to the gravitational separation equipment of complex ore of a kind of chute preparation equipment, particularly many metals, many mineral, relates in particular to a kind of rolling chute.
Background technology
Chute is the one of common chute preparation equipment, and be one of effective equipment being separated proportion two or more mineral discrepant, chute ore dressing is the reselecting method utilizing inclined-plane stream to carry out sorting mineral in chute.Namely ore pulp flows through from groove face, and ore particle is subject to the effect of current loose and forms laminar flow by density stratification, and upper strata light mineral flows fast, lower floor's heavy mineral reduced velocity flow, thus realizes light, heavy mineral separation;
Chute preparation equipment common at present has fixed chute, point contracting chute, vibration upset chute, belt chute, spiral chute, separating cone, Johnson's ore separators etc.Wherein vibration upset chute, belt chute, spiral chute, separating cone, Johnson's ore separators are can the ore deposit optional equipment of continuous operation, but due to the limitation of these equipment, the scope of application of vibration upset chute, belt chute, spiral chute, separating cone is restricted, the scope of application is less, and Johnson's ore separators becomes the first-selection of ore deposit optional equipment because its floor space is little, equipment investment is few, production efficiency is high, output is large.
As shown in Figure 1, to the structure of Johnson's ore separators its structure arrange liner at cylinder inner surface, and the section configuration of described liner is the groove of zigzag genesis analysis.During the work of Johnson's ore separators, along with the rotation of cylindrical shell, groove produces certain lateral shear effect to the ore pulp flowed downward along barrel, thus forms turbulent flow, and current upwards carry out loose to ore pulp body, are beneficial to mineral gravity segregation.The heavy mineral falling within lower floor concentrates on groove, is finally brought to cylindrical shell top, washes away heavy mineral to concentrate in concentrate hopper discharge cylindrical shell by flushing water.Based on this, the defect existing for Johnson's ore separators is: 1, Johnson's ore separators can only carry out sorting by the mineral smaller to granularity, can not carry out sorting, granularity narrow application range by the mineral larger to fineness ratio; 2, Johnson's ore separators can only carry out a sorting, if carry out repeatedly sorting to mineral, and realize thick, scan operation and preliminary selected multiple operations, then need miscellaneous equipment just can complete.
Utility model content
For the weak point that above-mentioned prior art exists, the utility model provides a kind of rolling chute realizing continuous operation, go for rough sand mineral, fine sand mineral, mineral in granular form carry out sorting, the granularity scope of application is wider, can complete on an equipment simultaneously ore pulp thick, scan operation and preliminary selected, for the follow-up ore deposit choosing of mineral is provided convenience.
To achieve these goals, the technical solution of the utility model is:
A kind of rolling chute, comprise can be rotated about axis cylindrical shell, for supporting the supporting arrangement of cylindrical shell and the driving section making barrel body rotation, be connected with cylinder bearing device, the inner circle outline line of described cylindrical shell is inclined to set, and has a relatively high point and a relative low points; The inwall of described cylindrical shell from one end of relatively high point to one end of relative low points arranges the blend stop of a minimum helix; Described cylindrical shell is provided with tailings discharging cover in one end of relative low points, and described cylindrical shell is provided with feed chute and heavy sand concentrate discharging cover in one end of relatively high point, the port of export of described feed chute extends in cylindrical shell; Be provided with wash tub pipe in described cylindrical shell, extend to the other end from one end of cylindrical shell.
As the improvement to technique scheme, the port of export of described feed chute is near one end of the relatively high point of cylindrical shell, and the described port of export is positioned at 1/3 ~ 1/2 length range of cylindrical shell.
As the improvement to technique scheme, the part that described wash tub pipe is being positioned at cylindrical shell is distributed with several apopores along its length.So, on any point in barrel lenght direction, flushing operation can be carried out to mineral.
As the improvement to technique scheme, described cylindrical shell be have certain cone angle divergent-cone wall or for tilt, cylindrical tube at an angle to the horizontal direction.
According to the difference of selected ore pulp, as the improvement to technique scheme, the height of described blend stop is 5 ~ 50 ㎜.
According to the difference of selected barrel diameter, as the improvement to technique scheme, the pitch between the blend stop of described helix is 500 ~ 1000 ㎜.
As the improvement to technique scheme, described bracing or strutting arrangement is arranged at the two ends of cylindrical shell, and described bracing or strutting arrangement comprises supporting base, be fixed on underframe seat, described supporting base is provided with bearing block, between the bearing block described in two, is provided with roller carrier shaft, described roller carrier shaft is provided with carrying roller; Described cylindrical shell is provided with wheel belt on a corresponding position, and described carrying roller and wheel belt offset, and does support and the transmission of cylinder.
As the improvement to technique scheme, described driving section, comprise motor, decelerator and shaft coupling, described shaft coupling is connected with one of them roller carrier shaft, and described motor is in transmission connection by decelerator, shaft coupling, roller carrier shaft, carrying roller, wheel belt and cylindrical shell.
Ore pulp is fed by feed chute, enters and rolls sorting in cylinder, moves downward under the effect of current along wall, light, heavy suite laminated segregation gradually in motion process.Because cylinder inboard wall is provided with the blend stop helically of certain altitude (the process raw material different with sludge according to coarse grain, particulate is arranged), turbulent flow can be formed at blend stop place after the ore pulp of flowing runs into blend stop, material is obtained loose, be conducive to light, heavy suite to be separated further, and make heavy mineral stay inside blend stop, light mineral then can be crossed blend stop and continue to move downward, until reach the barrel tip edge of relative low points, and discharges through tailings discharging cover; And the heavy mineral stayed inside blend stop, due to the rotation of cylinder, spiral blend stop produces impetus to it, can move upward along barrel, because the effect of flushing water constantly obtains selected in process, until the barrel front end edge arriving relatively high point is discharged through heavy sand concentrate discharging cover, thus achieve separation and the continuous seepage of different densities mineral.
Compared with prior art, the beneficial effects of the utility model are:
Rolling chute of the present utility model, continuous operation can be realized, go for rough sand mineral, fine sand mineral, mineral in granular form carry out sorting, the granularity scope of application is wider, can complete on an equipment simultaneously ore pulp thick, scan operation and preliminary selected, for the follow-up ore deposit choosing of mineral is provided convenience.
