The overflow pipe is connected to the top of the cyclone body, and is connected with the cyclone body, the overflow The bottom of pipe is deep into the inside of the cyclone body, and the upper end of the overflow pipe is provided with overflow cap, overflow pipe insertion depth It is that overflow pipe is inserted into a section length inside cyclone, refers to overflow bottom of the tube to the distance of cyclone top cover.Ordinary circumstance Under, reduce overflow pipe insertion depth, concentrate concentration step-down;Increase overflow pipe insertion depth, concentration concentration uprises;But it is excessive, lose Remove concentrated effect.Usual overflow pipe insertion depth h=(0.3-0.7) D, D are the internal diameter of cylindrical tube;
The sand settling mouth is detachably connected with the cyclone body by flange, and underflow pipe is provided with inside the sand settling mouth And sand sediment pipe, the underflow pipe connect with the sand sediment pipe, the underflow pipe is in cone-shaped, and the sand sediment pipe is cylindrical, institute Sand sediment pipe is stated in the downside of the underflow pipe.
The beneficial effects of the utility model are:
(1) tangential velocity is improved using the first larger cone of angle, then with less second cone of angle Effective residence time of fine grading is improved, under the conditions of cone total height is equal, it can obtain higher than conventional cyclone Multi-stage PCE performance and bigger disposal ability.Realize fine fraction classification, the compact cloth of bocca angle of major diameter cyclone Office, have the advantages that disposal ability is big, partition size is thin, stilling productivity and sand setting concentration are high compared with conventional cyclone, thus Suitable for the concentration operation of cyclone;
(2) by changing the sand settling mouth of different size, for different materials, different cone ratios is obtained, it is optimal to obtain Multi-stage PCE effect.
Further, flange is passed through respectively between the cylindrical tube, the first cone, the second cone and the 3rd cone It is fixedly connected.
Further, the cyclone body inwall uses polyurethane material.
It is using the beneficial effect of above-mentioned technical proposal:Using polyurethane material, increase the service life of cyclone.
Further, the taper of first cone, the second cone and the 3rd cone is followed successively by 10 °, 8 °, 5 °.
Further, the taper of first cone, the second cone and the 3rd cone is followed successively by 20 °, 8 °, 7 °.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional view of the present utility model;
In the accompanying drawings, the list of designations represented by each label is as follows:1st, charging aperture, 2, overflow pipe, 3, cylindrical tube, 4th, the first cone, the 5, second cone, the 6, the 3rd cone, 7, sand settling mouth, 8, overflow cap.
Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality It is new, it is not intended to limit the scope of the utility model.
As shown in Figure 1 and Figure 2, a kind of concentration-type cyclone, including overflow pipe 2, charging aperture 1, sand settling mouth 7 and in hollow knot The cyclone body of structure, the lower end of the cyclone body are connected with the sand settling mouth 7, the cyclone body include on to Under the cylindrical tube 3, the first cone 4, the second cone 5 and the 3rd cone 6 that are sequentially connected, first cone 4, The taper of two cones 5 and the 3rd cone 6 is sequentially reduced;
All sidepieces of the cylindrical tube 3 are provided with the charging aperture 1, and the charging aperture 1 connects with the cyclone body;
The overflow pipe 2 is connected to the top of the cyclone body, and is connected with the cyclone body, the overflow The bottom of pipe 2 is deep into the inside of the cyclone body, and the upper end of the overflow pipe is provided with overflow cap 8, and overflow pipe 2 inserts depth Degree is that overflow pipe is inserted into a section length inside cyclone, refers to overflow bottom of the tube to the distance of cyclone top cover.General feelings Under condition, reduce overflow pipe insertion depth, concentrate concentration step-down;Increase overflow pipe insertion depth, concentration concentration uprises;But it is excessive then Lose concentrated effect.Overflow pipe insertion depth h=(0.3-0.7) D, D are the internal diameter of cylindrical tube;
The sand settling mouth 7 is detachably connected with the cyclone body by flange, and the inside of sand settling mouth 7 is provided with underflow Pipe 7-1 and sand sediment pipe 7-2, the underflow pipe 7-1 connect with the sand sediment pipe 7-2, and the underflow pipe 7-1 is described in cone-shaped Sand sediment pipe 7-2 is cylindrical, and the sand sediment pipe 7-2 is in the downside of the underflow pipe 7-1.
Consolidated respectively by flange between the cylindrical tube 3, the first cone 4, the second cone 5 and the 3rd cone 6 Fixed connection.
The cyclone body inwall uses polyurethane material.
The taper of first cone 4, the second cone 5 and the 3rd cone 6 is followed successively by 10 °, 8 °, 5 °.Described The taper of one cone 4, the second cone 5 and the 3rd cone 6 is followed successively by 20 °, 8 °, 7 °.
Operation principle of the present utility model is as follows:
Ore pulp tangentially enters cyclone body with higher speed by charging aperture 1, due to being limited by barrel, Liquid does top-down rotary motion, and this motion generally is referred to as into contour stealth or declines swirling motion.
Solid particle in contour stealth is by centrifugal action, if density is more than the density of surrounding liquid, (this is most Number situation), the centrifugal force suffered by it is bigger, once this power is more than because of liquid resistance caused by motion, solid particle is just Can overcome this resistance and be moved to wall direction, reach particle near wall by continuous liquid-driving, along wall to Lower motion, arrival underflow opening collect around the ore pulp as high concentration, discharged from sand sediment pipe 7-2.
Liquid (wherein also having some tiny particles certainly) rotation after isolation of purified continues to move downwards, into circular cone Duan Hou, because the internal diameter of cyclone hydraulic separators is gradually reduced, liquid in rotation speed accelerate, due to liquid produce eddy motion when radially The pressure distribution in direction is uneven, it is smaller at axis and arrive axis when level off to zero, turn into low-pressure area even region of no pressure, Liquid is caused to be intended to axis direction movement;Simultaneously as hydrocyclone underflow mouth is substantially reduced, liquid can not be rapidly the bottom of from Flow tube 7-2 is discharged, and the overflow pipe 2 in vortex chamber top cover center, due to making a part of liquid be moved to it in low-pressure area, because And upward rotary motion is formed, and discharged from overflow pipe 2.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in Within the scope of shield.
