Abstract

An ore pulp classifying cyclone separator comprises a spiral feed pipe section, a straight pipe section and a conical pipe section connected as a whole orderly; the top of the feed pipe section is arranged with an overflow pipe; the bottom of the conical pipe section is provided with an underflow port. superfine particles are hydraulically classified by a centrifugal force field, so that the ore pulp flowing into the feed pipe section is flow limited by an external cylinder of the feed pipe section, and an upper cover and an cylinder wall, forcing the feed influent rotating up to down in the straight pipe section and the conical pipe section, and large centrifugal force is formed during the rotation of the feed influent; the coarse particles are gradually thrown to the external wall under the centrifugal force, and are fallen down rotationally along the external wall surface under the force of gravity until being discharged out of the underflow port. The rotationally falling external spiral flow is gradually centralized in the center under the impact of taper shrinkage, and can return for lifting when falls to a proper degree and then becomes a rotational movement up to down; the fine particles lift with the spiral to the internal spiral flow and are discharged out of the overflow pipe on the top, so that the classification is completed, and the classifier efficiency is high; the utility model is wearable and has small floor space and low energy consumption.

Description

The ore pulp classifying cyclone
Technical field
The utility model relates to the ore pulp classifying cyclone, is particularly useful for the hydraulic classiciation of metal, nonmetal ore pulp.
Background technology
At present, the device of superfine material wet classification mainly contains spiral classifier and cyclone, its structure is at open type log washer tiltably-mounted, the bottom of groove is semicircle, ore pulp feeds from the middle part, the classified groove of fine particle lower end downflow weir is discharged, and after the coarse fraction product settles down, is transported to the log washer upper end by conveying worm and discharges.Use spiral classifier minuteness particle is carried out classification, its classification efficiency is low, generally has only about 50%, does not satisfy production requirement.Though more existing hydraulic classiciation cyclones are being used,, ubiquity weak point in service life, the shortcoming that classification efficiency is still lower.
Summary of the invention
At the problem that prior art is deposited, the purpose of this utility model provides a kind of simple in structure, easy to use, wear-resisting, ore pulp classifying cyclone that classification efficiency is high.
The technical scheme in the invention for solving the technical problem is: it is made of the spiral charging pipeline section, straight length and the Taper Pipe section that are linked in sequence to one, and the top of charging pipeline section is provided with overflow pipe, and the bottom of Taper Pipe section is provided with underflow opening.
Described charging pipeline section exine shells body is an equiangular spiral shape, and involuted angle is 90 °~180 °, and the inwall and the cylindrical shell of charging pipeline section are tangent; All be lined with the compound rubber-plastics material of wear-resisting organic polymer in all pipeline sections; Described Taper Pipe section can be made up of several sections Taper Pipes.
Hydraulic classiciation is carried out to minuteness particle in the utility model applying centrifugal force field, adopt difform pipeline section combination, make the ore pulp that enters the charging pipeline section owing to be subjected to the current limliting of charging pipeline section outer cylinder and loam cake and inner cylinder wall, force materials flow in straight length and Taper Pipe section, to do top-down rotatablely moving, in the materials flow rotary movement, form very big centrifugal force, coarse granule is under centrifugal action, be thrown toward outer wall gradually, and in gravity effect lower edge outside wall surface rotation whereabouts, until discharging from underflow opening.The outer eddy flow that rotation descends compiles to the center gradually because of the influence that is subjected to the cone contraction, begin to return rising when dropping to a certain degree, form one rotatablely moving from bottom to top, eddy flow was discharged by the overflow pipe at top in fine grained rose to spiral, thereby reached the purpose of classification.Be applicable to metal, ore pulp such as nonmetal carried out classification, compared with prior art, the classification efficiency height, wear-resisting, floor space is little, energy consumption is low.
Description of drawings
Fig. 1 is the utility model classifying cyclone structural front view.
Fig. 2 is the A-A figure of Fig. 1.
Among the figure: 1-charging pipeline section, 2-straight length, 3-Taper Pipe section, 4-underflow opening, 5-overflow pipe.
The specific embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
Shown in Figure 1, whole classifying cyclone is made up of charging pipeline section 1, straight length 2, Taper Pipe section 3, underflow opening 4, overflow pipe 5.Straight length 2 tops are connected with charging pipeline section 1, and straight length 2 bottoms are connected with Taper Pipe section 3, and according to on-the-spot needs, Taper Pipe section 3 can be made up of multistage, are three sections compositions among Fig. 1.Taper Pipe section 3 belows are provided with underflow opening 4, and underflow opening 4 is replaceable.Overflow pipe 5 is located in the charging pipeline section 1, and charging pipeline section 1 outer wall housing is equiangular spiral (logatithmic spiral) shape, and involuted angle is 90 °~180 °, and charging pipeline section 1 inwall and cylindrical shell are tangent, shown in Figure 2.Connected in the cyclone that pipeline section forms and to be lined with the compound rubber-plastics material of wear-resisting organic polymer, according to partition size and required precision, the depth-adjustment that overflow pipe 5 inserts is put in order by each, and underflow opening 4 is replaceable to be different inner diameters.With pump ore pulp is pressed in the charging pipeline section 1, enter the ore pulp of charging pipeline section 1 owing to be subjected to the current limliting of charging pipeline section 1 outer cylinder and loam cake and inner cylinder wall, force materials flow in straight length 2 and Taper Pipe section 3, to do top-down rotatablely moving, be outer eddy flow, form very big centrifugal force in the materials flow rotary movement, coarse granule is thrown toward outer wall gradually under centrifugal action, and in gravity effect lower edge outside wall surface rotation whereabouts, until discharging from underflow opening 4; The outer eddy flow that rotation descends compiles to the center gradually because of the influence that is subjected to the cone contraction, begin to return rising when dropping to a certain degree, form one promptly interior eddy flow that rotatablely moves from bottom to top, eddy flow was discharged by the overflow pipe 5 at top in fine grained rose to spiral, thereby reached the purpose of classification.By insertion depth or change underflow opening 4 diameters that change overflow pipe 5, can regulate partition size.
