Embodiment 1

[0037] 1. Embodiment 1: Select basic components to assemble a three-channel internal mixing nozzle.

[0038] Such as Figure 5 As shown, select an end cover 1, two internal mixing rings 2 and three moving rings 4, and assemble with a crystallizer 9. The installation process is:

[0039]The adjustment thread 4-5 of the first moving ring 4 is installed with the adjustment nut 5, and the upper side of the adjustment nut 5 is screwed into the adjustment thread 1-3 on the end cover 1, and the direction of rotation of the adjustment thread 1-3 is the same as that of the adjustment thread 4-5. The direction of rotation is opposite, the adjusting nut 5 rotates left and right, and at the same time, the sub-port 1-6 of the end cover 1 is installed together with the upper side boss 4-2 of the moving ring 4, and the sealing ring 7 is installed in the sealing groove 4-1; the moving ring 4 The lower side boss 4-2 of the first internal mixing static ring 2 is installed together with the up...

Embodiment 2

[0047] 2. Embodiment 2: Select basic components to assemble a four-channel external mixing nozzle.

[0048] Such as Figure 6 As shown, select one end cover 1, three outer mixing static rings 3 and four moving rings 4, and assemble with one crystallizer 9. The installation process is:

[0049] Install the adjustment nut 5 on the adjustment thread 4-5 of the first moving ring 4, screw the adjustment thread 1-3 on the end cover 1 into the other side of the adjustment nut 5, and adjust the direction of rotation and adjustment of the adjustment thread 1-3. The thread 4-5 rotates in the opposite direction, and the adjusting nut 5 rotates left and right. At the same time, the sub-port 1-6 of the end cover 1 is installed together with the upper boss 4-2 of the moving ring 4, and a sealing ring is installed in the sealing groove 4-1. 7; The lower side boss 4-2 of the moving ring 4 is installed together with the upper side sub-port 3-2 of the first outer mixed static ring 3, and the ...

Embodiment 3

[0055] 3. Embodiment 3: Select basic components to assemble a four-channel internal and external mixing nozzle.

[0056] Such as Figure 7 As shown, select one end cover 1, one inner mixing static ring 2, two outer mixing static rings 3, four moving rings 4, and assemble with a crystallizer 9. The installation process is:

[0057] The adjustment thread 4-5 of the first moving ring 4 is equipped with an adjustment nut 5, which is screwed into the adjustment thread 1-3 of the end cover 1. The direction of rotation of the adjustment thread 1-3 is opposite to that of the adjustment thread 4-5, and the adjustment nut 5 is Rotate left and right, and at the same time, the sub-port 1-6 of the end cover 1 is installed together with the upper side boss 4-2 of the first moving ring 4, and the sealing ring 7 is installed in the sealing groove 4-1; the lower side boss of the moving ring 4 4-2 is installed together with the upper sub-port 2-2 of the inner mixing static ring 2, the center ...

Abstract

The present invention relates to superfine powder preparing apparatus, and is especially one kind of combined supercritical fluid nozzle for preparing superfine material. The combined supercritical fluid nozzle consists of end caps, moving ring, inner fixed mixing ring, outer fixed mixing ring, crystallizer, and other basic members. It may be assembled into a multichannel internal mixing nozzle, amultichannel external mixing nozzle, a multichannel internal-external mixing nozzle or a fast expanding nozzle for jetting material and mixing materials. The present invention has compact structure,small size, easy manufacture, wide application range and other advantages.

Description

1. Technical field [0001] The invention belongs to nano-micron material or ultrafine powder preparation equipment, in particular to a combined nozzle for supercritical fluid nano-micron material preparation. 2. Background technology [0002] At present, most of the nozzle holes in supercritical fluid nano-micron material preparation equipment are elongated holes, which are made by laser drilling and other methods, so as to ensure a very small hole diameter. However, the nozzle with this conventional structure is difficult to process and the manufacturing cost is high; and because the material is easy to be partly separated out at the nozzle hole, it is easy to block and difficult to dredge; because the nozzle aperture is very small and the flow area is small, even if multiple nozzles are used, It is also difficult to increase the production output of nano-micron materials, and the production efficiency is low; in addition, because the nozzle aperture cannot be adjusted, it i...
