Description

Technical Field

[0001] This utility model relates to the field of airflow pulverization technology, and in particular to an airflow pulverization device for hexamethylenetetramine. Background Technology

[0002] The airflow pulverizer, along with a cyclone separator, dust collector, and induced draft fan, forms a complete pulverizing system. Compressed air, after being filtered and dried, is injected at high speed into the pulverizing chamber through a Laval nozzle. At the convergence point of multiple high-pressure airflows, the material is repeatedly pulverized through collision, friction, and shearing. The pulverized material, under the suction of the fan, moves with the rising airflow to the classification zone. Under the powerful centrifugal force generated by the high-speed rotating classification turbine, coarse and fine materials are separated. Fine particles that meet the particle size requirements pass through the classification wheel and are collected by the cyclone separator and dust collector, while coarse particles descend to the pulverizing zone for further pulverization.

[0003] However, existing air jet mills still have certain drawbacks: they are limited by the size of the material during use. When the material entering is too large, the air jet mill has difficulty effectively crushing the object, which affects the actual finished product and thus the quality of the finished product.

[0004] Therefore, based on actual needs, the applicant discovered a method that adds a screening device to the material inlet end, so that materials that meet the requirements of the air jet mill can enter the fluidized bed for crushing. When the size of the material cannot pass through the holes of the screen, it will fall out along the waste outlet end, so that the incoming materials can be effectively crushed and the quality of the finished product is improved.
