The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used to illustrate the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 2, be the structural representation of the bubble type atomizer of the embodiment of the invention, bubble type atomizer provided by the invention comprises: handle 1, external gear 2, positioning pressuring plate 3, internal gear compressing tablet 4, a plurality of adjustable plate 5, bubble generate plate 6 and cavity 7.
Wherein, cavity 7 comprises the cylindricality cavity 71 and the cone-shaped cavity 72 of connection, and cone-shaped cavity 72 is set to nozzle shape away from cylindricality cavity 71 1 ends, and bubble generates plate 6 and is arranged in the cavity 7 inner cylindricality cavitys 71, is connected by screw thread with cylindricality cavity 71.As shown in Figure 5, it is a circular platy structure that bubble generates plate 6, the slave plate center outwards is radial several through holes 61 that is evenly distributed with, through hole 61 evenly is arranged in bubble and generates plate 6 central region, the through hole 61 that is positioned at outmost turns forms regular hexagon, and the submarginal zone that generates plate 6 at bubble is evenly distributed with several fixing holes 62.Fixing hole 62 is used for being connected with adjustable plate 5.The through hole of present embodiment also can be arranged as other shape, as other geometries such as square, octagons.The fixing hole number of present embodiment also can be provided with according to actual needs and flexibly.
Internal gear compressing tablet 4 is arranged in the cylindricality cavity 71, is connected with adjustable plate 5, also is connected with a joggle with external gear 2, is used to control to adjust the rotation of plate 5.Particularly, as shown in Figure 3, internal gear compressing tablet 4 comprises the gear teeth 41, evenly offers several pin-and-holes 42 on the interior gear teeth compressing tablet 4; The gear teeth 41 are connected with a joggle with external gear 2.
External gear 2 parts are arranged at cylindricality cavity 71 inside, are used to drive internal gear compressing tablet 4 and rotate, and handle 1 is fixedly set in the central part of external gear 2, are used to control external gear 2 and rotate, and handle 1 can be connected with external gear 2 by nut.
Preferably, present embodiment also comprises positioning pressuring plate 3, is used to limit internal gear compressing tablet 4 along cavity 7 axial moving, and places the disengaging between internal gear compressing tablet 4 and the external gear 2; Internal gear compressing tablet 4 all is connected by the inwall of screw thread with cylindricality cavity 71 with positioning pressuring plate 3, stops when with positioning pressuring plate 3 space of about 1mm being arranged when internal gear compressing tablet 4 rotates to.
Present embodiment rotates by rotating regulating handle 1 drive external gear 2; Corresponding rotation by also taking place with external gear 2 engagements in internal gear compressing tablet 4; Internal gear compressing tablet 4 cooperates with joint pin 52 on the annular flake 51 by the pin-and-hole 42 on it, and the annular flake 51 of drive adjustable plate 5 rotates; Further change the quantity that adjustable plate 5 covers through hole 61, realize the accurate adjusting of gas-liquid flow-rate ratio.
The workflow of the bubble type atomizer of present embodiment is as follows: when liquid enters cavity 7 inside of bubble type atomizer, flow to the through hole 61 that bubble generates plate 6 through positioning pressuring plate 3, internal gear compressing tablet 4 and adjustable plate 5.The aperture of this through hole 61 is much smaller than cavity 7 internal diameters, and therefore, fluid stream therein is shunk, and flow velocity can increase.The increase of flow velocity is accompanied by the reduction of fluid pressure, therefore, when pressure drops to saturated vapour pressure under the liquid corresponding temperature when following, will produce gas, finally can form the mixture of gas-liquid two-phase.Through behind the through hole 61, a fluid stream expansion enters bigger zone, but pressure can not return to original pressure, and therefore, gas-liquid two-phase flows and still exists.At last, finish the bubble type atomizing from the nozzle shape one end ejection of cone-shaped cavity.
In sum, bubble type atomizer provided by the invention has compared with prior art been save other introducing gas, is easy to realize closed cycle; Gas-liquid flow and the two ratio can be regulated easily, the atomizing uniformity can be accurately adjusted; And this apparatus structure is simple, is easy to realize.
It should be noted that at last: above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technical scheme.
