Line inductance electromotor, pinching structure 7 shape those skilled in the art can according to the technique and scheme of the present invention expect simultaneously
Easy to implement, the embodiment of the present invention does not illustrate excessively.
The detailed process of separation method of the present invention is：
S1：Drop injection of separation device is placed in horizontal table top, makes monolithic stability, must not shake；
S2：According to different liquids, select unlike material, size pinching structure 7；Such as when liquid is tap water, acquisition
The drop of 1.37mm, it is 16mm to select annulus set caliber, and the material of annulus set is quartz glass tube；When liquid is organic solvent
When, the pinching structure 7 of annulus set or regular polygon set is selected, material is quartz glass；When liquid is metal liquid, selection circle
The pinching structure 7 of ring set or regular polygon, material are the high metal of fusing point.
For same liquid, annulus set or other regular polygon sets can achieve the object of the present invention.
S3：Droplet liquid to be separated is placed in beaker, and is placed on immediately below pinching structure 7；
S4：Adjust the position of limited block 4 so that 7 half of pinching structure is submerged in beaker liquid；
S5：It is required according to drop, adjusting control device 5, and starts line inductance electromotor, line inductance electromotor reaches peak
After retract minimum point, and so on；
S6：Wait for drop AEI After End of Injection, stop control 5.
In order to utilize " pinching " process to complete the injection of separation of drop, pinching structure 7 has to major part and is submerged in liquid
In, and ensureing that round set quickly rises straight up, speed is different according to the liquid of different viscosities.
The present invention realizes the vertical injection of separation process of drop, and casts out nozzle, due to cylindrical linear induction motor two
The hollow-core construction size ratio nozzle of secondary side 3 is much larger, prevents spray nozzle clogging.
The example of the present invention is described in detail above, but content is only the preferred embodiment of the present invention, no
