Powder wall-breaking machine

Abstract

A wall breaking machine for the powder including pollen, ganoderma spores, etc is composed of a suction-in chamber, a high-pressure airflow-powder mixing chamber and a wall-breaking chamber, in which there is an inclined target plate for colliding with the high-speed powder.

Description

technical field [0001] The invention belongs to the technical field of ultrafine powder. The invention proposes a device capable of superfinely pulverizing powder and achieving wall breaking. Background technique [0002] Powder wall breaking is the key technology to effectively extract the active ingredients in a single powder and improve the activity of the powder. Usually, the powder wall breaking is the same as the ultra-fine grinding, and the powder is crushed by physical methods, and the powder is crushed during the crushing process. Broken. The physical method is mainly based on the crushing method. The crushing method is a kind of borrowing various external forces, such as mechanical force, flow capacity, sound energy, etc., to act on the object to be crushed to crush the solid block and achieve a very fine The particle size and the purpose of breaking the wall. At present, in the industry, the most commonly used pulverizers in laboratories include ball mill pulve...

Problems solved by technology

[0006] The micro-jet crushing method is to use high-pressure liquid to accelerate through the injector to form a high-speed jet, which drives the solid particles to be crushed to move at high speed. The jet carrying the particles forms a high-pressure collision with the target plate or another jet in the opposite direction. Due to the strong The impact of the impact makes the solid material in it crushed. The advantage of this crushing method is that the crushed particle size is small and relatively uniform, but the disadvantage is that the high-pressure liquid is usually required to reach 200MPa, which brings great pressure on equipment manufacturing and production processes. In addition, due to the intervention of high-pressure liquid, the later separation is far more difficult than the separation with air as the medium, and affects the purity of the product.

In addition, the design and installation of the target plate are at right angles to the high-speed jet, so that the stagnant layer formed between the high-speed jet and the target plate is not easy to spread, which affects the crushing effect of the micro jet pulverizer to a certain extent.
