Background technology
At present, the three products heavy medium cyclone branch that has been widely used in coal is chosen.Its representative instance is a kind of large-scale pressureless fed three-product dense-medium cyclone that relates in the Chinese patent application 02158903.8 disclosed " a kind of heavy medium cyclone device, coal separation system and coal preparation method ".This kind heavy medium cyclone is composed in series by the first cylindrical section shape cyclone and the conical cyclone of second cylindrical section, the mounted angle (central axis and horizontal sextant angle) of its first cylindrical section shape cyclone is 20 °, and the mounted angle of the conical cyclone of second cylindrical section is 0 °.The investment of this kind heavy medium cyclone is little, and cost is low, and the superiority that reliability is high has obtained embodiment in a plurality of coal washerys that with ore dressing plant, Divine Land, Shanxi coal electricity coking limited company Jin Yang are representative.
Along with further developing of large-scale heavy medium cyclone, the diameter of cyclone constantly increases, and causes the hypertonia to Jie, increases the adjusting difficulty of power consumption and wearing and tearing and big flow, sharpness of separation reduces, and causes above-mentioned three products heavy medium cyclone can not satisfy demand of practical production sometimes; In addition, the used heavy-media suspension density of above-mentioned three products heavy medium cyclone is many below 1.6kg/L, and therefore this three products heavy medium cyclone can not (non magnetic ore of separating density 〉=2.0kg/L) carries out effective sorting to the separating density height; Simultaneously, this three products heavy medium cyclone can not obtain economical, effective sorting to high percentage of shale content raw ore.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of taper how for a kind of high-efficiency and energy-saving type three products heavy medium cyclone that is situated between with pre-sorting.
Solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of high-efficiency and energy-saving type three products heavy medium cyclone, it comprises one section unpressurized feeding cyclone and two sections the feed cyclone of pressure and tube connector, one section unpressurized feeding cyclone and two sections have the feed cyclone of pressure and tube connector to be connected in series, it is characterized in that: the cylindrical shell of described one section unpressurized feeding cyclone is taper, and bevel angle θ is between 0 °～40 °; One section unpressurized feeding cyclone is provided with Jie's of confession mouths more and presorts selected introductions matter inlet; One section unpressurized feeding cyclone and two sections have the feed of pressure cyclone all to adopt high inclination-angle to install.
Compared with prior art, the utility model can carry out sorting to the high density mineral effectively, is specially adapted to the mineral of separating density greater than 2.0kg/L, is a kind of high-efficiency and energy-saving type equipment that can realize the gravity separation of high density sorting.The application of this kind cyclone can make the sorting of non magnetic ore become simply, economical, efficient, remarkable in economical benefits.Have advantages such as production technology is simple, production cost is low, environmental pollution is little.
As mentioned above, major advantage of the present utility model is:
1. ribbing coal losses in can reducing reduces the pollution of heavy product to light product, eliminates cleaned coal dirt band phenomenon simultaneously, improves sharpness of separation.
2. can reduce pressure, cut down the consumption of energy.
3. concentrated effect strengthens, and has reduced Media density, has improved two sections separating densities, and stronger to the difficult separation coal applicability.
Description of drawings
Fig. 1 is the structural representation of high-efficiency and energy-saving type three products heavy medium cyclone;
Fig. 2 is a suspension inlet A-A generalized section among Fig. 1;
Among the figure, light product outlet 1, mouthful 2 (2～10 for the mouths that are situated between) that supply to be situated between more, one section cyclone 3 is presorted selected introductions matter inlet 4, raw ore inlet 5, tube connector 6,7, two sections cyclones 8 of heavy product outlet, intermediate product outlet 9.
The specific embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is further described.
The utility model has the feed of pressure cyclone 8 by one section unpressurized feeding cyclone 3 and two sections, and tube connector 6 is composed in series, its improvements over the prior art part is: one section cyclone 3 is conical cyclone, bevel angle is between 0 °～40 °, and the one end is provided with many for mouth 2 and the light product outlet 1 of being situated between, number for the mouth that is situated between is 2～10, and the other end is provided with presorts selected introductions matter inlet 4 and raw ore import 5; The mounted angle α of one section cyclone 3 is between 15 °～50 °, and the mounted angle β of two sections cyclones 8 is between 0 °～90 °, and two sections have an end of pressing feed cyclone 8 to be provided with heavy product outlet 7, and the other end is provided with intermediate product outlet 9.
Many numbers for the mouth 2 that is situated between of one section unpressurized feeding cyclone 3 one end of the utility model can be designed to 2～10 according to the specified suspension flow of cyclone.The quantity that adds Frequency Converter Control in the pump of 2～10 confession Jie mouths is decided on mineralogical property, simultaneously, regulates size and the pressure that feeds cyclone suspension liquid measure according to the variation of mineralogical property.Size shape for the mouth 2 that is situated between can be identical also can having nothing in common with each other according to concrete needs.Layout for the mouth 2 that is situated between can be on same plane, also can be in Different Plane.For the mouth 2 that is situated between can be even layout when same horizontal layout, also can be inhomogeneous layout.
During the raw ore sorting, at first low-density suspension is fed one section cyclone 3 by many for getting involved mouth 2 and presorting selected introductions matter inlet 4, feed two sections cyclones 8 through tube connector 6 again, thereby the flow and the pressure that form suspension in the high-efficiency and energy-saving type three products heavy medium cyclone all meet the stable centrifugal field that separation operation requires; Then raw ore is fed from raw ore inlet 5.Raw ore is subjected to obtain preliminary sorting from presorting the effect of the selected introductions matter inlet 4 formed centrifugal field of suspension that feed, and after the promptly pre-sorting, enters one section cyclone 3.Under the effect of centrifugal force in one section cyclone 3, light product and part suspension product outlet 1 are on the lenient side discharged, and heavy mineral and all the other the suspension tube connector 6 between one section cyclone 3 and two sections cyclones 8 enters two sections cyclones 8.Under the effect of centrifugal force in two sections cyclones 8, heavy product and a part of suspension are discharged from heavy product outlet 7, and intermediate product and remaining suspension are discharged from middle product outlet 9, can finish the separation operation to mineral.
