Problems solved by technology

In this way, it is necessary to make multiple nozzles for different material preparation and research needs, which greatly increases the cost of material preparation and research
In addition, the existing nozzle aperture is very small, the number of nozzles is limited, the amount of prepared nano-micron materials is small, the efficiency is low, and the measurement and detection errors are large

Abstract

The invention belongs to the nanometer micro material preparing device, which especially relates to an external mixed hypercritical fluid nanometer micro material preparing nozzle. The invention is formed by a nozzle main body and a taper end sheath and a collector which are mounted on the main body; wherein, the tail of said main body is a nozzle core; the main body and the taper end sheath are positioned by positioning surface, locked by screw connection and adjusting locking element, and sealed by sealing ring; the taper end sheath and the nozzle core form the annular slit as the nozzle; the nozzle via the feeding channel of main body is connected to the material feeding channel; the collector is outside the main body and the taper end sheath to be fixed on the main body; the collector has a valve. The invention has reasonable structure which can mix several materials synchronously to be sprayed, to realize external mixed hypercritical fluid nanometer micro particle preparation. The annular slit of nozzle can be adjusted easily to avoid jam and prepare smaller particle. The invention can reduce the cost and improve the efficiency.

Description

1. Technical field [0001] The invention belongs to nano-micro material preparation equipment, in particular to an external mixing supercritical fluid nano-micro material preparation nozzle. 2. Background technology [0002] At present, the nozzle holes in supercritical fluid nano-micron material preparation equipment are mostly made by laser drilling and other methods, so as to ensure a very small hole diameter. Because the material is partly separated out at the nozzle hole, it is easy to block. Such a very small nozzle hole is not easy to dredge, and the material and production cost of the nozzle are very high, so once it is blocked, it will cause great waste. In addition, since the size of the nozzle aperture has a great influence on the preparation of nano-micron materials, it is an important factor affecting the preparation process, so the nozzle should be replaced frequently in material preparation, especially in material preparation research. In this way, multiple no...
