Because the utility model hydrocyclone has adopted technique scheme, be that this hydrocyclone comprises cyclone pipe, feed pipe, overflow pipe, outer tube and dividing plate, described cyclone pipe is straight tube top closure, bottom end opening, described outer tube top closure, bottom is tapered opening, described cyclone pipe is positioned at described outer tube coaxial setting, described overflow pipe penetrates described outer tube top and stretches into described cyclone pipe inner chamber, described feed pipe level is located at described outer tube top and to be tangentially communicated with the cavity between described outer tube and cyclone pipe, described cyclone pipe is in tube wall some rectangular through-hole uniformly at intervals of described feed pipe position, the axis of described some rectangular through-hole and described cyclone pipe inner circle are tangent, described dividing plate center has through hole and level is located in described outer tube, described dividing plate is positioned at below, described cyclone pipe bottom.This hydrocyclone has overcome the defect of traditional cyclone, has improved the swirl flow time of material, makes material have more obviously initial whirlpool, has effectively improved the separating effect of material.

Brief description of the drawings

Below in conjunction with drawings and embodiments, the utility model is described in further detail:

Fig. 1 is the structural representation of conventional hydrocyclone;

Fig. 2 is the structural representation of the utility model hydrocyclone;

Fig. 3 is that the A-A of Fig. 2 is to zoomed-in view.

Detailed description of the invention

As Fig. 2, shown in Fig. 3, the utility model hydrocyclone comprises cyclone pipe 1, feed pipe 2 and overflow pipe 3, also comprise outer tube 4 and dividing plate 5, described cyclone pipe 1 is straight tube top closure, bottom end opening, described outer tube 4 top closure, bottom is tapered opening, described cyclone pipe 1 is positioned at described outer tube 4 coaxial setting, described overflow pipe 3 penetrates described outer tube 4 tops and stretches into described cyclone pipe 1 inner chamber, described feed pipe 2 levels are located at described outer tube 4 tops and to be tangentially communicated with the cavity between described outer tube 4 and cyclone pipe 1, described cyclone pipe 1 is in tube wall some rectangular through-hole 12 uniformly at intervals of described feed pipe 2 positions, the axis of described some rectangular through-hole 12 and described cyclone pipe 1 inner circle are tangent, described dividing plate 5 centers have through hole and level is located in described outer tube 4, described dividing plate 5 is positioned at described cyclone pipe 1 below, bottom.

Further, this hydrocyclone also comprises pallet 6 and siphon pipe 7, described pallet 6 is located at described cyclone pipe 1 bottom and is positioned at described dividing plate 5 tops, described siphon pipe 7 is positioned at the cavity of described cyclone pipe 1 and outer tube 4, and described siphon pipe 7 bottoms penetrate described dividing plate 5 and pallet 6 and are communicated with described cyclone pipe 1 inner chamber.The siphonal center air column producing when effective elimination cyclonic action is set, makes more clear liquids be excluded by siphon pipe, increases de-water ratio, meanwhile, along with the elimination of air column, make cyclone can further reduce partition size, make the thinner impurity of granularity separated.

Further, this hydrocyclone also comprises blowoff valve 8, and described blowoff valve 8 is located at the tapered open end of described outer tube 4.The underflow opening of conventional hydrocyclone is for often opening, and therefore cyclone can only separate concentration and split ratio by regulating underflow opening size regulate, but can produce inevitably impact to effluent concentration when regulating.This hydrocyclone arranges blowoff valve in the tapered open end of outer tube, the underflow opening of cyclone is adopted to regular switch, its advantage is to ensure the impregnable while of effluent concentration, realize the further sedimentation separation that underflow has separated turbid solution, regularly switch blowoff valve, directly obtain large concentration fluid, the cyclone that underflow density is often opened apparently higher than traditional underflow opening.

Each parts of this hydrocyclone can be by being welded to connect, feed pipe 2 is connected material inlet pipe 22 by flange 21,31 respectively with overflow pipe 3 and clear liquid goes out pipe 32, outer tube 4 is interval with adpting flange 41 and installs for equipment, material enters after this cyclone from material inlet pipe 22, clear liquid goes out pipe 32 through overflow pipe 3 from clear liquid and flows out, and turbid solution is flowed out by the tapered open end of outer tube, or through blowoff valve periodical blowdown; This hydrocyclone changes the entrance form of conventional hydrocyclone, form secondary rotation by some rectangular through-hole of feed pipe and cyclone pipe tube wall and be connected access road, material is realized High Rotation Speed in advance by the one-level access road of feed pipe, utilize space between one-level passage and secondary passage and the mobility of material self, the secondary passage that material is made up of some rectangular through-hole with best corner cut automatically enters in cyclone pipe; Its advantage is that the complexity of saving artificial manufacture Tangential Channel is manufactured link, and the cut-in manner of material is cut according to minimum drag mode according to mechanism characteristic by fluid completely, and corner cut is more accurate.Traditional cyclone of single-stage input relatively, this cyclone of multistage input has more obvious advantage more, its entrance quantity is many, make current there is more obviously initial whirlpool, thereby can ensure under the prerequisite of swirl flow, significantly increase the straight section length of cyclone pipe, increase the eddy flow time, reach the object that improves separating effect; In addition the increase of initial eddy flow, can more significantly reduce the short-circuit flow (short-circuit flow does not participate in eddy flow, is directly flowed out by overfall with virgin pulp liquid concentration) producing between overflow pipe and cyclone pipe, thereby improve the separating effect of this hydrocyclone.
