Description

Multi-stage atomizing spray head

Technical Field

The application relates to a multi-stage atomizer.

Background

Liquid atomization is a process of processing liquid into tiny liquid drops through a corresponding device and spraying the tiny liquid drops in a mist shape. With the progress of science and technology and the development of modern industry, the atomization technology becomes an important practical technology and is widely applied in many engineering fields and daily life, such as agricultural spraying, industrial dedusting, efficient combustion, medical drug delivery, film-coating isolation, adhesion and leakage prevention and the like.

As shown in FIG. 1, a possible two-component cross-linking atomizer comprises a first feed liquid channel 13 and a second feed liquid channel 14, wherein the original components in the two channels are mixed and cross-linked and then pushed out from a narrow gap. The mixed feed liquid bears high pressure in the spray head, and the pressure drops suddenly after the mixed feed liquid is sprayed from the small holes, so that the liquid can be diffused into mist. The nozzle has the advantages of simple structure, high production efficiency and low cost, and can be conveniently produced and applied on a large scale. However, the atomizing angle is large and the spraying range is wide in clinical use, and the two components are gelatinized and easily cured after being mixed and crosslinked to block a spray head, so that the clinical effect is unsatisfactory.

As shown in fig. 2 and 3, the embodiment of the present application proposes a multi-stage atomizer head 100, which includes a head body 1, a feed liquid pipe, and an atomizing member 4.

The nozzle body 1 comprises a gas channel, a feed liquid channel and an axial cavity 15. In the present embodiment, the gas passages include a first gas passage 11 and a second gas passage 12. The feed liquid channel comprises a first feed liquid channel 13 and a second feed liquid channel 14. The feed liquid conduit comprises a first feed liquid conduit 2 and a second feed liquid conduit 3.

The multi-stage atomizing spray head of the embodiment can be suitable for multi-component colloid, for example, the A component and the B component are separately stored and mixed to form the colloid when in use. A. The liquid of the component B respectively enters the spray head body 1 from the inlets of the first feed liquid pipeline 2 and the second feed liquid pipeline 3, and is sprayed on the working surface after mixing, crosslinking and atomizing.

The axial cavity 15 may be disposed in the nozzle body 1 to extend in the axial direction a, and the axial cavity 15 is used for accommodating an atomizing ring 49 of the atomizing element 4. The tail end of the axial cavity 15 is communicated with a spray hole part 17 of the multi-stage atomizing spray head.

The upstream ends of the first gas passage 11, the second gas passage 12, the first feed liquid passage 13, and the second feed liquid passage 14 may form an opening at the top of the showerhead body 1, and the downstream end may be communicated to the axial chamber 15.

At least the end section of the gas passage may be arranged obliquely to the axial direction a and at least the end section of the feed liquid passage may be parallel to the axial direction a. The ends of the gas channels and the ends of the feed liquid channels may converge together, for example the ends of the first gas channel 11 and the first feed liquid channel 13 may converge together and the ends of the second gas channel 12 and the second feed liquid channel 14 may converge together. The filtered high-pressure gas is passed into the first gas passage 11 and the second gas passage 12. The in-process that uses has high-pressure gas to spout from the gas passage end always, and high-pressure gas can help the atomized liquid to also can constantly dash out the feed liquid in the shower nozzle, clean shower nozzle avoids the colloid solidification to block up the shower nozzle.

The first feed liquid pipe 2 is connected to the inlet end of the first feed liquid channel 13 and the second feed liquid pipe 3 is connected to the inlet end of the second feed liquid channel 14. The multi-stage atomizing spray head is connected with the injector through a feed liquid pipeline. Both the first feed liquid pipe 2 and the second feed liquid pipe 3 may be elastic pipes such as medical silicone tubes.

The atomizing member 4 may include an atomizing ring 49 and an atomizing ring connecting rod 41, and one end (a lower end in fig. 2, 3) of the atomizing ring connecting rod 41 is connected to the atomizing ring 49. The atomizing ring 49 may be cylindrical and provided with the atomizing holes 43, the atomizing ring 49 and the atomizing ring connecting rod 41 may be connected by a connecting piece 44, and the connecting piece 44 may avoid the ends of the feed liquid channel and the gas channel, so that the ends of the feed liquid channel and the gas channel are aligned with the atomizing holes 43.

The outer peripheral surface of the atomizing ring 49 may be provided with an airflow groove 42 extending in the axial direction a. The gas flow groove 42 may communicate with the first gas passage 11 and the second gas passage 12. It is understood that in other possible embodiments, the air flow groove 42 may be formed on the inner circumferential surface of the axial cavity 15, or neither the atomizing ring 49 nor the axial cavity 15 may be formed with another groove, and the annular gap between the atomizing ring 49 and the axial cavity 15 may also be used as the air flow groove 42. The gas flowing out through the gas flow groove 42 can control the spraying range of the atomized liquid droplets, thereby realizing more accurate spraying effect and preventing the liquid droplets from adhering to the side wall of the spraying hole part 17. It is understood that in other possible embodiments, the length of the atomizing ring 49 in the axial direction a may be greater than the length of the axial cavity 15 in the axial direction a, so that the gas in the gas passage can smoothly enter the gas flow groove 42.

The portion of the hub cavity 15 surrounding or housing the atomizing ring 49 may have an inner diameter less than the inner diameter of the orifice portion 17 on its underside. The atomizing ring 49 may have an outer diameter smaller than an inner diameter of the orifice portion 17, which may also prevent the ejected liquid droplets from adhering to the side wall of the orifice portion 17.

The feed liquid channel is closer to the axis cavity 15 than the gas channel, the inner diameter of the feed liquid channel can be smaller than that of the atomizing ring 49, and the pressure of the feed liquid is suddenly reduced after the feed liquid is ejected from the feed liquid channel and can be diffused into mist, so that the feed liquid sprayed out from the feed liquid channel can be preliminarily atomized in the atomizing holes 43. The ends (outlet ends) of the first feed liquid channel 13 and the second feed liquid channel 14 correspond to the atomizing holes 43 of the atomizing ring 49 so that the feed liquid can pass through the atomizing ring 49 from the atomizing holes 43 of the atomizing ring 49. The ends (outlet ends) of the first gas channel 11 and the second gas channel 12 also correspond to the atomizing holes 43, so that the high-pressure gas can pass through the atomizing holes 43 to prevent the cross-linked and solidified colloid from blocking the atomizing ring 49.

The atomizing spray head of the embodiment can realize three-stage atomization, and the atomization effect and the multi-component crosslinking effect are good.

Primary atomization: the liquid can realize primary atomization when sprayed out from the small-diameter feed liquid channel.

Secondary atomization: in the central hole of the atomizing ring, the primarily atomized liquid drops are blown away by high-pressure gas and collide and sputter with the inner wall surface of the atomizing ring, so that the primarily atomized liquid drops are collided and mixed, and secondary atomization is realized.

Third-stage atomization: the liquid drop after the second grade atomizing enters into the jet orifice portion that the internal diameter is bigger, realizes tertiary atomizing, and the high-pressure gas that flows out through the air current groove collides with the liquid drop of secondary atomizing for tertiary atomizing's effect is better.
