SU1496836A1 - Apparatus for dropping liquids - Google Patents

Abstract

The invention relates to the technique of spraying and can be used in the design of equipment used in the manufacture of powder materials from melts. The goal is to enhance the functionality and increase work efficiency. For this, the droplet generator is provided with supports for securing the resonator and means for adjusting the tension of the resonator, which is hollow and communicates with the spinneret and the liquid feeder. The droplet generator is also provided with racks for limiting the oscillating part of the resonator, which are installed with the possibility of longitudinal movement. On one of the racks placed generator of mechanical vibrations. The droplet generator makes it possible to significantly reduce the length of the unbroken part of the jet while maintaining the power of the oscillator, as well as to break up viscous liquids by increasing the modulation depth and heating the die and working fluid to reduce viscosity. The use of heated liquids is possible due to the location of the generator of mechanical vibrations outside the zone of outflow of the liquid, which prevents the generator of vibrations from destruction. 2 hp f-ly, 4 ill.

Description

The invention relates to the improvement of the technology of spraying liquids and can be used in the design of equipment used in the manufacture of powder materials from melts.

The purpose of the invention is to enhance the functionality and improve performance.

FIG. 1 shows a droplet generator, a general view; in fig. 2 — node 1 in FIG. one; in fig. 3 shows a variant of the droplet generator, general view; in fig. 4 — node II in FIG. 3

The droplet generator comprises a spinneret 1 connected to a liquid feeder 2 and installed with a working surface 3 on the resonator 4, and a generator 5 of mechanical vibrations.

The resonator 4 is fixed on the supports 6 and 7, provided with a means of adjusting its tension in the form of a screw 8 and is hollow and communicated with the spinneret I and the liquid feeder 2.

In addition, the generator is equipped with racks in the form of clamps 9 and 10 with shelf II for limiting the oscillating part of the resonator 4, installed with the possibility of longitudinal movement. Pipe 12 serves to supply fluid to the droplet generator.

Generator drops works as follows.

The working fluid from the liquid feeder 2 under pressure through the pipe 12 is fed to the die 1, the working surface 3 of which is fixed on the resonator 4, tensioned between two supports 6 and 7 by means of a screw 8. The generator 5 of mechanical oscillations, such as a piezoelectric transducer connected to a generator

sinusoidal oscillations of adjustable frequency, provides excitation of the resonator 4. Simultaneously with the resonator 4, making transverse oscillations with a frequency determined by adjustable tension and length of the resonator, frequency of the piezoelectric element, oscillatory movements are made by the working surface 3 of the spinneret 1, fixed in the center of the resonator 4, At the same time, the flow rate of the liquid is modulated and stimulates the disintegration of the jet into droplets due to the Rayleigh instability. The piezoelectric transducer is located on the movable latch 9 with one side touching the shelf 11,
