Abstract
The utility model discloses an air atomization device, particularly relates to a supersonic dry fog nozzle, which comprises a resonance main body (1), a Laval nozzle (2) and a harmonic oscillator (4), wherein a nozzle (6) is arranged on the top portion of the resonance main body (1), a resonance cavity (7) is arranged in the resonance main body (1), the harmonic oscillator (4) is arranged between the resonance cavity and the nozzle (6), the Laval nozzle (2) stretches into the resonance main body (1), a liquid guide cavity (5) is arranged between the Laval nozzle (2) and the resonance main body (1), the liquid guide cavity (5) is communicated with the resonance cavity, and the tail portion of the Laval nozzle (2) is connected with an air guide cavity (3). The supersonic dry fog nozzle speeds up the air by utilizing the Laval nozzle in super sound mode, then the air knocks into the resonance cavity to produce secondary atomization after producing super sound atomization by being mixed with absorbed air, and 2-15 micrometer dry fog particles can be obtained. Furthermore, the supersonic dry fog nozzle is large in mechanical strength, reliable in performance and rapid in mounting and sealing, and is suitable for wide application.
Description
Technical field
The utility model relates to a kind of air atomizing device, relates in particular to a kind of supersonic speed Dry-fog spray nozzle.
Background technology
Atomizer is a kind of atomization of liquid can the ejection, and evenly is suspended in airborne a kind of device.Existing for air-atomized device, it is a kind of double-current build atomizer, its operation principle is to pass through internal pressure, the liquid of inside is squeezed in nozzle, nozzle interior is placed with an iron plate, swiftly flowing liquid knockout forms the atomizing particle of diameter 15-60 micron left and right, and sprays by jet expansion on iron plate after bounce-back.Atomizer is widely used in various spray products, such as: pesticide, air aromatic agent, reagent spray etc.But the atomizing particle that this nozzle causes is still excessive, can not satisfy special dimension to the atomizing demand of fine particle.
The utility model content
The purpose of this utility model is to provide a kind of supersonic speed Dry-fog spray nozzle, solves the excessive problem of particle of present atomising device atomizing.
For addressing the above problem, technical solution adopted in the utility model is:
A kind of supersonic speed Dry-fog spray nozzle, comprise that the top has resonance main body, Laval nozzle and the harmonic oscillator of spout, be provided with resonator in described resonance main body, harmonic oscillator is arranged between resonator and spout, described Laval nozzle stretch in the resonance main body and and the resonance main body between form the liquid introduction chamber, the liquid introduction chamber is connected with resonator, and the afterbody of described Laval nozzle is connected with the air introduction chamber.
Further technical scheme is that above-mentioned resonance main body resonant cavity is formed in one.
Further technical scheme is that above-mentioned resonance main body is provided with body seal ring mounting groove outward, and the afterbody of described air introduction chamber is provided with introduction chamber sealing ring mounting groove.
The beneficial effect that adopts technique scheme to produce is: the utility model utilizes Laval nozzle to come the air Supersonic is accelerated, and then mix the atomizing of generation Supersonic with the air that sucks after, strike again and produce secondary-atomizing in resonator, just can obtain the dry fog particle of 2-15 micron, in addition, mechanical strength of the present utility model is large, and dependable performance and installation edge sealing are quick, are fit to extensive use.
