Abstract
The utility model relates to an atomizing nozzle for spraying granulation, which comprises a feed pipe, a spraying cavity and an injection orifice, wherein the spraying cavity is ring-shaped, the cavity is internally provided with a plurality of arc guide pieces along the peripheral direction to be divided into an inner flow guide cavity and an outer flow guide cavity, the feed pipe is communicated with the outer flow guide cavity along the tangential direction, and the front end of each guide piece is embedded into the outer flow guide cavity arranged at the outer side of the front guide piece along the material flowing tangential direction, so that a feed port of the inner flow guide cavity is formed at a gap between the front guide piece and the back guide piece; and one axial side of the inner flow guide cavity is provided with a convex tapered compression cavity, wherein the conical degree alpha of the compression cavity is 120-150 degrees, and the injection orifice is arranged in the middle of the compression cavity. The high-speed rotational flow slurry is compressed by the tapered compression cavity, and is spread to the periphery at a high speed, so that the effect of forced atomization effect can be achieved, and the stability of the product quality can be guaranteed.
Description
Technical field
The utility model relates to a kind of refractory gunning equipment for slurry-spraying pelletizing, specifically a kind of atomizer for slurry-spraying pelletizing.
Background technology
Spurt into again in the material curtain of kiln body after in the granulation process of preneutralization production Diammonium phosphate (DAP), usually need to slip being atomized by nozzle, play the granulation effect.Nozzle majority commonly used need to atomize to slip by compressed air at present, sprays by nozzle again.The shortcoming of this refractory gunning equipment is that moisture contained in the compressed air can be brought in the slip by atomizing, has caused the uncontrollability of the sub-moisture of institute's granulation.
Summary of the invention
The purpose of this utility model provides a kind of atomizer for slurry-spraying pelletizing, need to can not atomize to slip by compressed air, and the impact that can avoid the moisture in the compressed air that the material for making clothes quality is brought can guarantee the stable of product quality.
The technical solution adopted in the utility model is: comprise feed pipe, spray cavity and jet, described injection cavity in the form of a ring, being provided with in the circumferential direction of the circle several piece arcuate guide sheet in the cavity is divided into cavity and is divided into inside and outside two diversion cavity, feed pipe communicates with outer diversion cavity in tangential direction, the front end of every prerotation vane embeds in the outer diversion cavity in the front prerotation vane outside, so that the gap between the forward and backward prerotation vane forms the charging aperture of interior diversion cavity along the tangential direction of material stream; An axial side of interior diversion cavity is provided with the tapered compression chamber of outside projection, and compression chamber tapering α is 120 °～150 °, and jet is located in the middle of the compression chamber.
By prerotation vane to the cutting that tangentially enters the slip that sprays cavity by feed pipe and the high-speed rotational that guiding reaches slip, the again further compression by the taper compression chamber, so that slip when the jet to around high speed diffusion, reach the by force effect of atomizing, solved the uncontrollability that causes particle moisture in the granulation process owing to compressed air.
Jet and feed pipe section ratio are that 1:8～10 are more suitable, both can keep higher spray pressure, and spray pressure can reach 0.6Mpa, and atomizing effect is good, can guarantee again enough whitewashing amounts simultaneously, can not affect granulation product.
Charging aperture is better for 1:10～14 with the overflow section ratio of outer diversion cavity.Slip is evenly entered in the interior diversion cavity by each charging aperture, can stablize the pressure that enters compression chamber, so that around the slip of jet ejection can be distributed to equably, improve atomizing effect.
As shown from the above technical solution, the utility model will be by entering the slip high-speed rotational of nozzle, further compress through the taper compression chamber again, so that slip when the jet to around high speed diffusion, reached the by force effect of atomizing, solve the problem that causes the uncontrollability of particle moisture in the granulation process owing to compressed air, can guarantee the stable of product quality.

The specific embodiment
The utility model structure as illustrated in fig. 1 and 2, comprise feed pipe 1, spray cavity 2 and jet 31, described injection cavity 2 in the form of a ring, being provided with in the circumferential direction of the circle several piece arcuate guide sheet 4,5,6,7 in the cavity 2 is divided into cavity and is divided into inside and outside two diversion cavity 21,22, the horizontal segment 11 of feed pipe 1 communicates with outer diversion cavity 21 in tangential direction, the front end of every prerotation vane embeds in the outer diversion cavity 21 in the front prerotation vane outside, so that the gap between the forward and backward prerotation vane forms the charging aperture 8 of interior diversion cavity 22 along the tangential direction of material stream; An axial side of interior diversion cavity 22 is provided with the tapered compression chamber of outside projection 3, and compression chamber 3 tapering α are 120 °～150 °, and jet 31 is located in the middle of the compression chamber 3.
Advance horizontal segment 11 enter slip in the nozzle along arrow 91 directions when outer diversion cavity 21 is made circular motion, the part slip is entered in the interior diversion cavity 22 by each charging aperture 8 respectively along arrow 92 directions, rotating and entering compression chamber 3, through jet 31 ejections of centre and twist to around diffusion.
