Abstract
The invention discloses a two-fluid atomizing nozzle used in spray drying equipment. The two-fluid atomizing nozzle comprises a distribution base and a nozzle, wherein the distribution base and the nozzle are fixed by a screw cap; an adjustable spray core is arranged between the distribution base and the nozzle; and the liquid distribution is realized by the spray core. The liquid spraying angle is increased through the spray core, so that the atomizing diameter is bigger, and the particle size is smaller; and the liquid is instantly dried after being contacted with hot air, so that the water content is lower, the heat exchanger between fog drops and the hot air is more sufficient, and the agglomeration phenomenon is prevented.

Background technology
The special internal structure design of twin fluid atomization nozzle can make liquids and gases Homogeneous phase mixing, realizes gas-liquid mixed atomization.In antibiotic spraying dry production technology, in the tower that second fluid nozzle is arranged on drying tower, apical position connects twin fluid atomization device.In actual production process, after feed liquid sprays from nozzle easily with tower body cone contact, fall at the bottom of tower after causing having a small amount of feed liquid to have bone dry, thus likely occur to glue tower or finished product water content high.Tracing it to its cause is that the scope of cut-out governing atomization angle of the prior art is too little, cause material and the hot air time short, make droplet and hot-air heat exchange insufficient, there is sticky tower caking phenomenon.
Summary of the invention
For solving the problems of the technologies described above, we have proposed a kind of twin fluid atomization nozzle, its objective is that providing a kind of regulates the nozzle that atomization angle scope is larger, solving the sticky tower caking phenomenon caused because heat exchange is insufficient.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of twin fluid atomization nozzle, comprise dispense font and nozzle, this dispense font centre position is provided with material hole, the surrounding in this material hole is provided with passage, described dispense font is fixedly connected with nozzle nut, and mixing tank for coating colors is formed in this nozzle, described material hole is all communicated with described mixing tank for coating colors with described passage, this nozzle is also provided with nozzle, exit towards the described material hole in nozzle direction is also embedded with an inner chamber, an adjustable spray core is provided with in described inner chamber, described spray core is by fixed leg, distribution block and regulating block are made of one piece, the external diameter of described fixed leg and the internal diameter of inner chamber match, described fixed leg and described distribution block inside are equipped with the material-distributing hole be interconnected, described material-distributing hole on fixed leg is communicated with the material hole in dispense font, described material-distributing hole in distribution block is communicated with described mixing tank for coating colors, described regulating block is crossing with the nozzle on nozzle, and the described regulating block of intersection is outward extending arc-shaped structure,
Also be provided with gas distributor between described dispense font and described spray core, described gas distributor is set on the fixed leg of spray core, and the surrounding of this gas distributor is provided with stacked flabellum.
Preferably, the junction of described dispense font and described nozzle is provided with pad.
Preferably, described material-distributing hole forms multiple passage in distribution block, and described passage is evenly distributed in described distribution block surrounding.
Preferably, the flabellum quantity of described gas distributor is six.
Pass through technique scheme, the beneficial effect that the present invention obtains is: by adding an adjustable spray core before feed liquid jetting nozzle, feed liquid is made to enter nozzle via the regulating block in spray core, increase the spray angle of feed liquid, being atomized diameter like this can be larger, and granularity can change little, with produce instantaneous drying after hot air, can reach less water content, droplet and hot-air heat exchange are more abundant, and prevent the phenomenon that sticky tower lumps;
By passage, the gas entered in mixing tank for coating colors becomes spiral air in the use of gas distributor, and feed liquid is sprayed twist, and such feed liquid mixing is more thorough, and heat exchange is more abundant, saves the energy.
