Problems solved by technology

[0005] Cutting and guiding the slurry tangentially entering the injection cavity through the feed pipe through the guide plate to achieve high-speed swirl flow of the slurry, and then further compressed by the conical compression chamber, so that the slurry flows to the surroundings at a high speed when passing through the injection port Diffusion achieves the effect of forced atomization and solves the uncontrollability of particle moisture caused by compressed air during the granulation process

Embodiment Construction

[0011] The structure of the present invention is as figure 1 and 2 As shown, it includes a feed pipe 1, an injection chamber 2 and an injection port 31. The injection chamber 2 is annular, and several arc-shaped guide vanes 4, 5, 6, 7 are arranged along the circumferential direction in the chamber 2. The cavity is divided into inner and outer guide chambers 21 and 22. The horizontal section 11 of the feed pipe 1 communicates with the outer guide chamber 21 in the tangential direction, and the front end of each guide piece is along the tangential direction of the material flow. Embedded in the outer guide cavity 21 on the outside of the front guide piece, so that the gap between the front and rear guide pieces forms the feed port 8 of the inner guide cavity 22; one axial side of the inner guide cavity 22 is provided with an outward convex Start with a conical compression cavity 3 , the taper α of the compression cavity 3 is 120° to 150°, and the injection port 31 is located in...

Abstract

The invention relates to an atomizing nozzle for spraying granulation. The atomizing nozzle comprises a feed pipe, a jet cavity and a jet orifice, wherein the jet cavity is annular; a plurality of arc-shaped guide sheets are arranged in the cavity along the circumferential direction for partitioning the cavity into an inner diversion cavity and an outer diversion cavity; the feed pipe is communicated with the outer diversion cavity along the tangential direction; the front end of each guide sheet is embedded into the outer diversion cavity on the outer side of the front guide sheet along the tangential direction of material flow, so that feeding holes of the inner diversion cavity are formed by gaps between the front and back guide sheets; one axial side of the inner diversion cavity is provided with an outwardly-projecting and conical compression cavity; the taper of the compression cavity is 120-150 degrees; and the jet orifice is formed in the middle of the compression cavity. High-speed rotational flow slurry is compressed by the conical compression cavity, and is dispersed towards four sides at a high speed through the jet orifice, so that the effect of forcibly atomizing is achieved, and stable product quality can be ensured.

Description

technical field [0001] The invention relates to a spraying device for spraying granulation, in particular to an atomizing nozzle for spraying granulation. Background technique [0002] In the granulation process of pre-neutralization to produce diammonium phosphate, it is usually necessary to atomize the slurry through the nozzle and then spray it into the material curtain of the kiln body to achieve the granulation effect. Most of the nozzles commonly used at present need to atomize the slurry through compressed air, and then spray it through the nozzle. The disadvantage of this spraying device is that the moisture contained in the compressed air will be brought into the slurry through atomization, resulting in the uncontrollability of the moisture content of the particles produced. Contents of the invention [0003] The purpose of the present invention is to provide an atomizing nozzle for spray granulation, which can atomize the slurry without the use of compressed air...
