Abstract

This invention provides a ""porous spraying method and device,"" where liquid is injected into the porous spraying device through a feeding port, and then flows to a vaporizing space of a vaporizing compartment from the spraying center through each liquid opening. Each venting hole in the vaporizing compartment will spray air to impact with the liquid flowing out of the liquid opening to perform the first vaporizing operation. The liquid then impacts each other again after the first vaporizing operation to perform the second vaporizing operation and form a circular swirl. Upon compressing the swirl, the liquid would be sprayed from the porous spraying device to form a burst thereby further reducing the size of liquid particles, which is the third vaporizing operation.

In the past, the spray nozzles used in the market to spray the droplets of the droplets are large, and in particular, they are subject to many restrictions, and the solution is ideal. The spray technique is mostly based on the single-hole technique, but through such a spray technique. When it is applied to the mass production of solid powder, there are many ways to solve this problem, but the big ^ does not break the if if if method ' is a liquid column that will stun the liquid with high pressure!: Top: to cool Forming a solid powder, using a high-pressure liquid point. ΐt) as the power of the atomized metal • 'There are two major defects ·· 〃 _ point, the shape of the powder made by the sample is irregular, and the surface is not bumpy. 'First Point 'These powders are easily oxidized or require more procedures to be cleaned by the surface oil; gas, f: spray technology method, using extremely high pressure gas (mostly nitrogen or t gas) to melt the liquid column Then, after cooling to form a solid powder, the method has two major drawbacks: First, the pressure required for the gas is very:, relative, the production cost is also increased; second, the yield is due to the fog Design, and Limited; the present invention have a view of the above, in the related industries are based on the design and

V. DESCRIPTION OF THE INVENTION (2) Years of experience in development, research [invention] The main object of the present invention is to use a spray method to make the liquid become a fine powder after solidification, and [embodiment] Development of the invention. The liquid to be atomized passes through a porous to atomized into extremely fine particles, and is cooled to be effective in achieving throughput. π Μ ΐ二? The first, fourth and eighth figures show the feed port of the feed head (丨〇) of ^ to the pipe (1 1 ), and maintain the proper temperature and agitation through the heating rod ', the rotary vane (1 5 1) in the pipe (1 1 ), and the liquid will enter the conical space (12) The cone (23) above the spray core (3) is evenly dispersed to each liquid hole (22), and flows from the liquid holes (22) to the atomization space of the spray chamber (3). At the same time as the above action, the air inlet (32) will inject a gas into the space (311), and a partial pressure (3" flows to the air holes (3 1 2) and flows out, simultaneously with The liquid flowing out of each liquid hole (22) collides, that is, the first atomization forms fine particles, and the center of the downward cone (24) is dispersed; the liquid holes (22) flow out of the particles, The lower cone (24), so the first atomization is the first time; and the outlet (34) is compressed, and the particles are made finer. See the second and third As shown in the figure, the liquid passes through the first The sub-atomized fine particles collide with each other and form an annular vortex. The fine particles are dispersed into finer particles, and the generated eddy current is generated after the spray chamber (30) is ejected through the outlet (34).
