Abstract

The invention provides a pneumatic atomizing nozzle. The pneumatic atomizing nozzle comprises a front end, a front portion, a middle portion, a rear portion and a tail portion and is made of stainless steel. The front end is designed to be of a circular truncated cone structure provided with a certain convex curved surface, so that cyclonic wind is formed by airflow in the nozzle and a cover, and thus chemical feed liquid can be split and atomized easily. In addition, the surface of the pneumatic atomizing nozzle is made of stainless steel, and certain finish is achieved; all contact parts can be sealed even under the condition that no sealing ring is arranged, and thus the chemical feed liquid is prevented from being contaminated by a sealing ring.

Description

technical field [0001] The invention belongs to the field of pharmaceutical machinery and equipment, in particular to an airflow atomizing nozzle for granulation. Background technique [0002] The air atomizing nozzle is a two-fluid nozzle (air and liquid) that uses the spraying effect of compressed air to atomize the material. The air atomizing nozzle is a device that interacts with the air flow and the liquid flow to generate a mist. This device is special The internal structure design can make the liquid and gas mix uniformly, and produce a fine droplet size spray or a coarse droplet spray. Typically, a finer droplet spray can be obtained by increasing the gas pressure or decreasing the liquid pressure, resulting in a higher gas flow rate than liquid flow rate. [0003] In the prior art, the front end of the atomizing nozzle is in the shape of a truncated cone, and the slope and the inner wall of the corresponding cap form two straight lines parallel or at a certain angl...
