Abstract
The utility model discloses a composite hydrocyclone used for the separation of two kinds of immiscible mediums. The hydrocyclone comprises of an inlet cavity, a flooding cavity, a static swirling separator, a hollow shaft, a rotating bar, a motor etc. The rotation of the rotating bar drives the liquid flow to rotate rapidly and further to realize the separation, which can ensure the quite high separation efficiency as well as can eliminate the influence on a swirling field of the vibration and avoids the increase of the cost which is caused by the high requirement towards the processing precision. The device is also applicable to the industries of the chemical industry, the metallurgical industry, the dye printing industry, the food industry etc. and has the wide application prospect.
Description
The utility model relates to oily water separation technique, specifically belongs to the design and the manufacturing technology of eddy flow oily water separating equipment.
Be used at present because the rotational flow separation equipment of water-oil separating mainly contains two kinds of static hydrocyclone and dynamic hydrocyclones.The pre-separation that static hydrocyclone such as Daqing oil field oil extraction No.1 Factory use static hydrocyclone (patent No. ZL96210084.6), its separation principle is to utilize the density contrast of two kinds of non soluble liquids, make liquid produce centrifugation, the formation of its rotational flow separation field is to provide by certain hydraulic coupling of coming, come liquid liquid to be rotated in the cyclone cone through the very little tangential inlet of sectional area, as seen the static hydrocyclone pressure loss is bigger, working condition is to external world had relatively high expectations, often be difficult to the separating effect that reaches desirable in the practice, separative efficiency is relatively low.Dynamic hydrocyclone (patent No. ZL98244285.8) is compared with static hydrocyclone, its eddy flow chamber produces rotation at a high speed by external impetus, the rotating ratio static type is high, improved separative efficiency to a certain extent, but its weak point is the stability of the vibration eddy flow field that power source produces and can brings certain influence, thereby influence separating effect, simultaneously because rotating part is longer, requirement to the rotating drum axiality is very high, has brought bigger difficulty and higher cost to processing and manufacturing.
The purpose of this utility model is exactly for overcoming the deficiency of above-mentioned two kinds of cyclones, a kind of compound hydrocyclone is provided, it can guarantee higher separative efficiency, can eliminate the influence of power source vibration to eddy flow field again, and the cost of avoiding the high manufacturing accuracy requirement to bring improves problem.
The purpose of this utility model is achieved by the following technical solution: this compound hydrocyclone partly is made up of entrance cavity, spill cavity, static rotational flow separation body, hollow shaft, rotation grid, motor etc.Wherein entrance cavity is the cylinder of a horizontal positioned, one section with section for conical and receive to the static cyclone separator of underflow opening and link to each other, the other end links to each other with spill cavity, the hollow shaft that the outside is fixed with the rotation grid is installed in spill cavity and the entrance cavity, separates by sealing device between entrance cavity and the spill cavity.The rotation grid can be vertical plate type or sped structure, and hollow shaft links to each other with the electrode that is fixed in ground by power transmission shaft.In spill cavity an end port radially have a spout hole, the other end has overflow lip along axis.
This compound hydrocyclone also can be designed as split type, and it is independent to be about to spill cavity, and motor drives the hollow shaft rotation with the band kind of drive.
The utility model compound hydrocyclone is owing to adopted motor-driven, and the tangential velocity height of fluid rotation can fully separate oil droplet in static rotational flow separation body, greatly improved efficiency of hydrocyclone; Do not participate in rotating owing to whole rotational flow separation body simultaneously, thus not high to manufacture process requirement, can reduce manufacturing cost greatly, and the influence to eddy flow field that can avoid motor oscillating to cause.This equipment also can be applied to industries such as chemical industry, metallurgy, printing and dyeing, food, has broad application prospects, and will bring huge economic and social benefit.
Below in conjunction with accompanying drawing structure of the present utility model is described in further detail.
Fig. 1 is the structural representation of compound hydrocyclone;
As shown in Figure 1, this compound hydrocyclone partly is made up of entrance cavity 3, spill cavity 1, static rotational flow separation body 6, hollow shaft 2, rotation grid 4, motor 9 etc.Wherein entrance cavity 3 is the cylinder of a horizontal positioned, one end is that conical static rotational flow separation body 6 links to each other with section, the other end links to each other with spill cavity 1, the hollow shaft 2 that the outside is fixed with rotation grid 4 is installed in spill cavity 1 and the entrance cavity 3, is spaced from each other by sealing device 8 between entrance cavity 3 and the spill cavity 1.Rotation grid 4 can be vertical plate type or sped structure, and hollow shaft 2 links to each other with the motor 9 that is fixed in ground by power transmission shaft, the end port in spill cavity 1 radially have a spout hole 7, the other end has overflow lip 5 along axis.During work, mixed liquor enters the entrance cavity 3 of compound hydrocyclone through coming the liquid pipeline, because hollow shaft 2 and rotation grid 4 produce rotation at a high speed under the driving of motor 9, liquid stream is forced to rotation when flowing through rotation grid 4, form the eddy current of rotation at a high speed.Eddy current is when the static rotational flow separation body 6 that migrates to vertically that taper shrinks, the eddy current of rotation is accelerated at a high speed, lightweight under action of centrifugal force, migrate to rotary fluid in be formed centrally oil nuclear, be discharged from after spout hole 7 arrives spill cavities 1 through the centre bore of overflow lip 5 and hollow shaft 2.Simultaneously heavy is rotated to the inwall of static rotational flow separation body 6 and continuation mutually and migrates to afterbody and discharge.
