The working principle or the using flow of the pneumatic control pulverizer for preparing the coarse cereal nutritional powder is as follows:
Coarse cereals are added into the feeding channel through the feeding hopper 10, a high-pressure airflow is introduced into the feeding channel through the air inlet pipe 11, materials in the feeding channel are sprayed into the crushing cavity 5, the high-pressure airflow is introduced into the crushing cavity 5 through the air inlet nozzle 3, high-speed rotational flow is formed, the coarse cereals are driven by the high-pressure rotational flow to do circular motion, and the coarse cereals and the inner liner 501 are continuously impacted, collided and rubbed to crush the coarse cereals;
The crushed coarse cereal particles enter the classifier 4 under the action of the suction force of the classifier 4, the fine particles are extracted and collected, and the large particles fall into the crushing cavity 5 to be crushed again after being blocked by the classifier 4;
After a certain time, stopping the material addition of the feeding channel and the entry of high-pressure air flow, starting the electric cylinder I8 to drive the two crushing cavities 5 to lift, so that the other crushing cavity 5 moves to a working position and is communicated with the feeding channel 2 and the air inlet nozzle 3, and the feeding channel 2 continuously conveys coarse cereals into the crushing cavities 5;
The air inlet pipe 203 and the air supply pipe 304 corresponding to the crushing cavity 5 at the rest position are respectively communicated with air supply equipment and a dual-purpose air pump, the air supply equipment supplies air to the inside of the cleaning ring 201, the surface of the liner 501 is purged through the purging nozzle 202, the dual-purpose air pump supplies air to the driving pipe 301, the extension pipe 302 is driven to extend, the cleaning ring 201 and the purging nozzle are driven to lift, and after a certain time, the dual-purpose air pump sucks air to the driving pipe 301, so that the extension pipe 302 is contracted, and the cleaning ring 201 is driven to move to the original position under the action of the reset spring 303;
When the liner 501 needs to be replaced, the dismounting plate 603 and the replacement plate 602 are opened, the swivel 601 is rotated to enable the replacement opening to rotate to the liner 501 needing to be replaced, the liner 501 is taken out from the crushing cavity 5, the replaced liner 501 is installed into the crushing cavity 5, and the replacement plate 602 and the dismounting plate 603 are installed.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
