Special rotary disc structure for liquid-by-liquid drop centrifugal atomization method

Abstract

The invention provides a special rotary disc structure for a liquid-by-liquid drop centrifugal atomization method. The special rotary disc structure is characterized by comprising a base body, an atomizing plane and vent holes, wherein the base body is a main body structure with a T-shaped longitudinal section, and the main body structure is composed of a bearing and connecting part at the upper part and a supporting part at the lower part, the upper surface of the bearing and connecting part is provided with a circular groove which is coaxial with a circle center of the bearing and connectingpart and the circular groove has a certain radius; the atomizing plane is of a disc structure, the disc structure cooperates with the circular groove and is in interference fit with the circular groove, and the atomization plane is made of a material with the wettability angle of an atomization melt smaller than 90 degrees; the vent holes are formed in the bearing and connecting part and the supporting part in a penetrating mode, the upper end faces of the vent holes are in contact with the lower end face of the atomizing plane, and the lower ends of the vent holes communicate with the outside. According to the structure, a split type rotary disc structure is mainly adopted, the material with good wettability with the atomized melt is used as the atomization plane of the rotary disc, a material which is poor in thermal conductivity is used as a base body of the rotary disc, so that the metal liquid drops can be well received in an atomizing and pulverizing process, and the spreading atomization of the liquid drop is facilitated.

Description

technical field [0001] The invention belongs to the technical field of preparation of ultrafine spherical microparticles, and in particular relates to a special turntable structure for a droplet-by-drop centrifugal atomization method. Background technique [0002] The receiving device of traditional centrifugal atomization mainly uses an integrated turntable structure, and the turntable is usually made of a material with poor wettability with the atomized alloy. At this time, the adhesion between the molten alloy and the surface of the turntable is small, which leads to The kinetic energy of the turntable to conduct the molten liquid film is very limited, and when the temperature and rotation speed of the melt are too high, the melt is prone to slipping, which seriously affects the atomization efficiency. [0003] In view of the poor atomization effect caused by the discomfort of the turntable structure in the traditional centrifugal atomization, it is necessary to redesign ...
