Embodiment
Below in conjunction with accompanying drawing, the present invention is described further:
A kind of compound hydrocyclone, comprise motor 1, damping device 2, oil-collecting chamber 3, oil outlet 4, drive shaft 5 and liquid inlet 6, also comprise rotatory 7, static swirler monomer 8 and overflow port 9, described drive shaft 5, rotatory 7 are positioned at oil-collecting chamber 3, described motor 1 is connected with drive shaft 5 by damping device 2, described drive shaft 5 one end damping device for connecting 2 the other end connects rotatory 7, and drive shaft 5 is hollow structure; Connect liquid inlet 6 and oil outlet 4 on top, oil-collecting chamber 3, described rotatory 7 is connected with static swirler monomer 8, and the end that rotatory 7 stretches in static swirler monomer 8 has overflow port 9; Connecting a synchronous rotating cylinder 10 outside described rotatory 7, this synchronous rotary cylinder 10 inwall is connected with the grid 11 of rotatory 7, and described synchronous rotary cylinder 10 comprises the gentle section of releasing 13 of the section of prewhirling 12; Bottom described static swirler monomer 8, there is water outlet 14.
In described rotatory 7, the quantity of grid 11 is three, and the length of rotatory 7 is between 100mm to 150mm, and the length of the section of prewhirling 12 is 100mm, and the length of the slow section of releasing 13 is 50mm, and described damping device 2 is rubber pad.
The useful effect of the present invention is: motor 1 is connected with drive shaft 5 by damping device 2, makes to turn into elasticity from being rigidly connected between motor 1 with drive shaft 5 and is connected, the transmission of damping vibration energy, it is possible to the work-ing life of extension device; Drive shaft 5 is hollow structure, because motor 1 adopts the mode of coaxial drive, so drive shaft 5 is necessary for tubular shaft, is convenient to oil core and is discharged to oil-collecting chamber 3, through oil outlet 4 remover apparatus; Appended synchronization rotating cylinder 10 outside rotatory 7, and extend the length of synchronous rotary cylinder 10, it is possible to improve oily water separation efficiency; By simultaneous test, quantity and length to rotatory 7 have all limited, it is possible to improve the efficiency of oily water separation.
The effect principle of this invention is: from structure, this equipment can be divided into two parts, i.e. power section and static swirler monomer segment, and power section mainly realizes the rotary motion of rotatory 7. Because oil and water are two kinds of immiscible liquid, there is density difference. When the mixture of two kinds of liquid mediums is entered by liquid inlet 6, under the driving of rotatory 7 high speed rotating, after in succession and the liquid come promotes and enters static swirler monomer 8 limit rotation edge axial motion, its helically shape of moving. According to moment of momentum conservation principle, its speed of rotation to be strengthened. When examining or check a certain lightweight phase dropping liquid, as oil dropping liquid radial direction by power time, due to the vortex motion of liquid, not etc., boundary is not higher, and nucleus is lower, and the drop in continuous phase liquid produces a centripetal difference force for the pressure distribution making radial direction; In addition when liquid produces rotary motion in chamber, in centrifugal field internal cause mass force effect, different liquid phase particle produces the reactive force of different size, and therefore oil drips and also there is a reactive force. Drop in again the motion in real liquid due to oil, certainly exist the stokes resistance that viscosity causes. So under the effect of these three power, oil drips the motion creating radial direction, and namely oil radially upwards flows out, and water then continues to flow in the horizontal direction.
From macroscopically, oil-water mixture is entered by the liquid inlet of compound hydrocyclone, through rotatory 7, liquid becomes, by translational motion, the motion that in static rotary fluid, rotation one axle center, edge is downward. Oil is separated in static rotary fluid with water like this, and oil core upwards moves along axle center, and outside overflow port 9 device for transferring, the water after separation is discharged from the water outlet of static rotary fluid. The oil outlet 4 arranged on top, oil-collecting chamber 3 is then the oily core isolated from oil-collecting chamber to gather.
The above is only the better embodiment of the present invention, is not the restriction that the present invention does other form. Any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations. But every not departing from technical solution of the present invention content, any simple modification, equivalent variations and the remodeling above embodiment done according to structure and the principle of work of the present invention, still belongs to the protection domain of technical solution of the present invention.
