Abstract

The utility model discloses an atomizing spray head, which belongs to an acoustic-energy atomizer, and is composed of a throat opening and a base body which is processed with mould cavities, such as a liquid feeding inner cavity, an air feeding inner cavity, a vibration chamber, a spray opening, etc. The utility model can be used for spraying even fine fog particles (most of the particle diameters of the fog particles are below 40 micrometers) under the operating condition that the air pressure is 0.2-0.5Mpa and the water quantity is 0.5-0.15t/h. The utility model can be applied to the fields of industrial dust removing, heavy oil burning, spray drying, etc.

Description

Atomized spray head

The utility model relates to a kind of atomizer, and it belongs to a kind of acoustic energy atomizer.Acoustic energy atomizer of the prior art as shown in the figure, it is made of head body 1, vibration cavity 2 and brace rod 3, its operation principle is: air sprays to vibration cavity 2 by the round cavity 4 of head body 1 through aditus laryngis 5, and forming ultrasonic field between the cavity 2 in head body 1 and vibration, liquid is entered ultrasonic field and is atomized through aditus laryngis 5 by one group of aperture 7 by ring-like cavity 6.Its advantage is to produce the fine droplet (particle diameter is mostly below 40 microns) that common atomizer is difficult to produce, but remains in the some shortcomings part:

1, bump against because of the outer surface of part droplet and brace rod 3 and vibration cavity 2 and condense into big water particle, the result causes droplet particle diameter inequality, has reduced atomizing effect.

2, because of the restriction of structure, the spray angle of mist and shape all are difficult to control.

3, processing difficulties.

4, outside vibration cavity 2 is exposed to, damage easily.

In view of the foregoing, the utility model intends providing a kind of rational in infrastructure, handling ease, solid and reliable and can produce the atomizer of even fine droplet.

The utility model is made of matrix 8 and aditus laryngis 9, be processed with die cavities such as feed flow inner chamber 10, air feed inner chamber 11, vibration chamber 12 and spout 13 on the matrix 8, aditus laryngis 9 and matrix 8 are by being threaded, its operation principle is that air communication is crossed air feed inner chamber 11 and injected the vibration cavity to produce ultrasonic field through aditus laryngis 9, liquid to be atomized enters ultrasonic field and is atomized rapidly through the feed flow inner chamber, and the fine droplet that is produced sprays through spout with air-flow.Advantage of the present utility model is:

1, spraying the place ahead is accessible, has improved the particle diameter uniformity, has stablized the spray effect that produces fine droplet.

2, can be by changing angle and the outlet shape that nozzle configuration changes spraying.

3, reduce manufacturing procedure and difficulty, reduced production cost.

4, compact conformation, solid and reliable.

Now in conjunction with the accompanying drawings the utility model is elaborated:

Figure one is an atomizer structure schematic diagram of the prior art, wherein, the 1st, head body, the 2nd, vibration cavity, the 3rd, brace rod, the 4th, round cavity, the 5th, aditus laryngis, the 6th, ring-like inner chamber, the 7th, aperture.

Figure two is the utility model structural representations, and wherein 8 is matrixes, and available stainless steel, copper or engineering plastics are as matrix material; The 9th, aditus laryngis, it with matrix 8 by being threaded; The 10th, the feed flow inner chamber, the 11st, the air feed inner chamber, the 12nd, vibration chamber 13 is spouts.After the utility model and source of the gas and water source connected, air sprayed into vibration chamber 12 and produces ultrasonic field through aditus laryngis 9 by the air feed chamber, liquid to be atomized enter by feed flow inner chamber 10 that ultrasonic field is atomized into fine droplet and with air through spout 13 ejections.

The utility model can be that the 0.2-0.5MPa and the water yield are to receive spray effect preferably under the condition of work of 0.05-0.15t/h at air pressure, spray the particle diameter of droplet mostly below 40 microns.

The utility model can be used for fields such as industrial dedusting, combusting heavy oil, spray-drying.

Claims

1, a kind of atomizer, it is characterized in that constituting by matrix 8 and aditus laryngis 9, be processed with feed flow inner chamber 10 on the matrix 8, air feed inner chamber 11, die cavities such as vibration chamber 12 and spout 13, matrix 8 and aditus laryngis 9 be by being threaded, and air communication is crossed air feed inner chamber 11 and injected vibration chamber 12 through aditus laryngis 9 and produce ultrasonic fields, liquid enters ultrasonic field by feed flow inner chamber 10 and is atomized, and droplet is by spout 13 ejections.
