In figure: 1 is support, 2 cylindrical linear induction motor primary sides, 3 is cylindrical linear induction motor secondary side, and 4 is limited block, and 5 is controller, and 6 for connecting electric wire, and 7 is pinching structure.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
As shown in Figure 1, the present invention includes support 1 and the cylindrical linear induction motor primary side 2 being arranged on support 1, with matching for hollow cylinder shape line inductance electromotor secondary side 3, cylindrical linear induction motor secondary side 3 is hollow cylindrical so that microlayer model can injection of separation from the bottom up in hollow cylinder body.
In addition present invention additionally comprises the controller 5 controlling cylindrical linear induction motor, the speed of cylindrical linear induction motor can regulate according to required droplet size, how many controlled device 5.Controller 5 is connected with power supply by connecting electric wire 6, power supply power.The adjustment of the controlled device 5 of the speed of service of cylindrical linear induction motor.
Further, for the drop separation of different liquids, installing corresponding removable pinching structure 7, pinching structure 7 and cylindrical linear induction motor secondary side 3 coaxial cooperation in cylindrical linear induction motor secondary side 3 lower end, the two has identical axis.Hollow cylinder shape line inductance electromotor secondary side 3 lower end and pinching structure 7 are threaded connection.According to the replaceable pinching structure 7 of different viscosities and liquid of different nature, pinching structure 7 is arranged on cylindrical linear induction motor secondary side 3 lower end, is replaced by the pinching structure 7 of different size and different materials during for different liquids.
Further, pinching structure 7 for annulus set or regular polygon set, as long as the solid structure of pinching effect can be produced, can be not limited in annulus set or regular polygon set.
Further, in order to prevent cylindrical linear induction motor secondary side 3 to depart from cylindrical linear induction motor primary side 2, at cylindrical linear induction motor secondary side, limited block 4 is installed.Limited block 4 is positioned at hollow cylinder shape line inductance electromotor secondary side about 3 two ends, the scope of moving-limiting.
Further, hollow upwards spraying to be able to make the microlayer model of formation to pass through, the inflated diameter of cylindrical linear induction motor secondary side 3 is maintained at 1-50mm, it is preferred to 10mm.
Further, the size of the speed decision drop of the diameter of annulus set, the character of liquid, rising.
Annulus set diameter is more big, and drop is more big；Liquid viscosity is more big, and drop is more little；The rate of climb is more big, and drop is more big.Such as, when the caliber of annulus set is 16mm, when using tap water, the rate of climb is 549.7mm/s, generates droplet size and is: 1.37mm.When the caliber of annulus set is 7mm, when using tap water, the rate of climb is 626.2mm/s, generates droplet size and is: 1.68mm.
Principle and the work process of enforcement that the present invention utilizes are as follows:
Cylindrical linear induction motor is used for providing the power of " pinching " for pinching structure 7." pinching " of liquid is that the process that the liquid contraction of adhesion is clashed into, when solid leaves liquid, liquid only can disconnect below solid when solid departs from liquid；When open circles ring-type solid vertically leaves, the liquid " pinching " in downside can cause shrinking liquid knockout, thus forming drop on axial location is hollow.
The present invention utilizes " pinching " effect, the liquid of surrounding is gathered shock to the central shaft of pinching structure 7, the drop clashed into can be produced in the hollow cylinder center of pinching structure 7, this drop has along axis component velocity upwards, ejects from the hollow-core construction of cylindrical linear induction motor secondary side 3 thus realizing drop.
In order to be able to whole process, effectively producing " pinching ", the effective travel of hollow cylinder shape line inductance electromotor secondary side 3 should be maintained at 5-25mm, regulates with specific reference to different liquids.
Such as: liquid is tap water, obtaining the drop of 1.37mm, when annulus set caliber is 16mm, annulus set is quartz glass tube, and the stroke of hollow cylinder shape line inductance electromotor secondary side 3 is 18.7mm.
It is further to note that, the line inductance electromotor of the present invention is not limited only to cylindrical linear induction motor, other line inductance electromotors such as platypelloid type line inductance electromotor and disc line inductance electromotor, as long as being equipped with suitable pinching structure 7, utilize principles of the invention and design all can realize the present invention, owing to shape those skilled in the art of platypelloid type line inductance electromotor and disc line inductance electromotor, pinching structure 7 can expect according to technical scheme and easily realize, embodiments of the invention do not do too much explanation.
The detailed process of separation method of the present invention is:
S1: be placed in horizontal table top by droplet jet segregation apparatus, makes monolithic stability, must not rock；
S2: according to different liquids, select the pinching structure 7 of unlike material, size；Such as when liquid is tap water, obtaining the drop of 1.37mm, selecting annulus set caliber is 16mm, and the material of annulus set is quartz glass tube；When liquid is organic solvent, selecting annulus set or the pinching structure 7 of regular polygon set, material is quartz glass；When liquid is metal liquid, selecting the pinching structure 7 of annulus set or regular polygon, material is the metal that fusing point is high.
For same liquid, annulus set or other regular polygon sets can realize the purpose of the present invention.
S3: droplet liquid to be separated is placed in beaker, and be placed on immediately below pinching structure 7；
S4: regulate the position of limited block 4 so that pinching structure 7 half is submerged in beaker liquid；
S5: according to drop requirement, regulable control device 5, and start line inductance electromotor, line inductance electromotor returns minimum point after arriving peak, and so forth；
S6: after droplet jet terminates, stop control 5.
In order to utilize " pinching " process to complete the injection of separation of drop, pinching structure 7 must major part be submerged in liquid, and ensures that circular set quickly rises straight up, and speed is different according to the liquid of different viscosities.
Present invention achieves the vertical injection of separation process of drop, and cast out nozzle, owing to the hollow-core construction size of cylindrical linear induction motor secondary side 3 is more much larger than nozzle, it is prevented that spray nozzle clogging.
Above the example of the present invention is described in detail, but described content has been only presently preferred embodiments of the present invention, it is impossible to be considered the practical range for limiting the present invention.All equalizations made according to the present patent application scope change and improvement etc., all should still belong within the patent covering scope of the present invention.
