Description
Technical field
The utility model relates to a kind of hydrocyclone composite set, belongs to two-phase medium separation equipment field.
Background technology
Hydrocyclone (Hydrocyclone) is widely used in the industrial departments such as mining, chemical industry, metallurgy, PETROLEUM PROCESSING, wastewater treatment and papermaking, its purposes mainly is to carry out the separation of two-phase medium, as solid-liquid separate, liquid-liquid of two kinds of immiscible fluid media separates and separates with solution-air etc., is a kind of multiduty device for effectively separating.
Why hydrocyclone becomes the separator of extensive use in each industrial department, be because have the unexistent advantage of other separator: (1), hydrocyclone can use under different occasions as required, for example but its decontaminating liquid in solid-liquid separates is removed wherein suspension and other solid impurity; (2), the structure of hydrocyclone is very simple, inner without any the moving component that needs repairing, consumable accessory and support member, its structure and container are quite similar, can connect with pipeline; (3), floor space is little, easy for installation, operating cost is also low, separation process is to finish under closed state fully, liquid after the purification and separated medium all can be carried by pipeline and reclaim, and realize closed cycle, can not produce pollution.
Hydrocyclone is made up of cyclone body, feeding mouth, overfall and underflow opening four parts usually.Cyclone body is made up of top cylindrical section and lower cone segments usually.Cylindrical section is called the eddy flow chamber, liquid is from tangentially entering the liquid stream that produces rotation at a high speed in the eddy flow chamber, the diameter in eddy flow chamber is the full diameter of hydrocyclone, the size of diameter has determined the disposal ability of hydrocyclone, and be the foundation (separating effect) of determining other parameter, the size of the interior cone angle of conical section influences the separating effect of hydrocyclone (cut point position).Inlet enters the cylindrical section of hydraulic cyclone body from the tangential direction of hydrocyclone.Overflow pipe is in the center of eddy flow body top cover.Underflow opening and eddy flow body and overflow pipe and equate with cyclone conical section small end internal diameter on same axis, in order to discharge the liquid after solid concentration strengthens.
When the material properties of need separation is similar, require the little hydrocyclone of design cylindrical section diameter, therefore select small diameter hydraulic cyclone usually for use, but the treating capacity of hydrocyclone is reduced.Publication number is that the Chinese utility model patent of CN20102741 discloses a kind of novel combined vertical solid-liquid hydrocyclone, its housing is divided into spill cavity, entrance cavity and underflow chamber by last lower clapboard, be fixed with a plurality of cyclone monomers between the last lower clapboard, the bottom in underflow chamber is conical, and the least significant end in underflow chamber is led to underflow opening.This hydrocyclone is combined the monomer hydrocyclone preferably.The low shortcoming of stability when but the conical section that has the monomer hydrocyclone cooperates with lower clapboard.
Summary of the invention
The utility model provides a kind of hydrocyclone composite set, its objective is that solving the conical section that has the existence of combined type hydrocyclone now lays problem of unstable.
For achieving the above object, the technical solution adopted in the utility model is: a kind of hydrocyclone composite set, comprise housing, last machine core board, following machine core board and hydrocyclone, and last machine core board and following machine core board are fixedly arranged on the housing, housing is divided into spill cavity, entrance cavity and underflow chamber
Multi-turn is evenly distributed a cylindrical hole around circumferentially being on the last machine core board; Stepped hole is offered in corresponding cylindrical hole position of going up machine core board on the following machine core board, and wherein, the axis of the cylindrical hole that the axis of each stepped hole is corresponding with it coincides; Described stepped hole is made up of two sections, and epimere is cylindrical enlarging, and hypomere is cylindrical or truncated cone-shaped, and two sections junctions form the ring-shaped step locating surface;
The cylindrical section diameter of hydrocyclone is greater than the conical section diameter, and two sections junctions form the ring-shaped step mating surface;
The cylindrical section of hydrocyclone stretches in the cylindrical hole of machine core board and is sealed and matched, and its conical section stretches into down the stepped hole of machine core board, the ring-shaped step mating surface is contacted with the ring-shaped step locating surface be sealed and matched.
Related content in the technique scheme is explained as follows:
In the such scheme, described round platform is meant that be 360 ° of derived geometrical bodies of rotating shaft rotation with right-angled trapezium perpendicular to the waist place straight line on base.Rotating shaft is called the axle of round platform.The disc that right-angled trapezium rotation of the upper and lower end is become is called the upper and lower bottom surface of round platform, the curved surface that another waist rotation is become is called the side of round platform, the waist of the right-angled trapezium of each position is called the bus of round platform on the side, the length of the trapezoidal waist on the axle of round platform is called the height of round platform, and the height of round platform also is the distance between upper and lower bottom surface.Round platform can think that also circular cone by two parts that vertical plane cut of its axle, therefore also can be " frustum of a cone ".
The utility model operation principle is:
Hydrocyclone give the ore deposit tight-lipped side by the following barrel portion of its loam cake, installing tangentially, overflow pipe and sediment outflow mouth dispose one on the other along the hydrocyclone axis direction.Under pressure, ore pulp enters hydrocyclone through giving the ore deposit mouth, portion produces rotational flow within it thus, more slightly, heavier particle dwindles the formation eddy current owing to suffered bigger centrifugal force gradually along tapered wall, quicken to the high speed direction of rotation owing to the fluid dynamic condition of continuity, the coarse granule ore pulp that is concentrated flows out from end mouth, and thin, be subjected to less centrifugal force than light grains, be pressed against in the middle eddy current of backflow, and, be referred to as overflow by middle fairlead (overflow pipe) outflow.The present invention utilizes the combination of small diameter hydraulic cyclone both to improve separating effect, has increased treating capacity again.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, because hydrocyclone of the present utility model is evenly distributed on the movement, and therefore, the ore pulp that enters each hydrocyclone also is stable and uniform, the separating effect of each hydrocyclone is also consistent.
2, because the utility model is vertical structure, and floor space is little, and is simple in structure, the situation of open that upper end cover just can be observed, whether the abrasion condition of testing fixture inwall and hydrocyclone stopping up.
3, because the number of elements of hydrocyclone of the present utility model can be regulated (using the mould the same with the hydrocyclone size to substitute) according to the size for the treatment of capacity, flexibility is strong.
