Abstract

The invention discloses a two-fluid nozzle. The two-fluid nozzle comprises a base, a liquid connection pipe and a flow confluence module. The base is cylindrical, and provided with a first end surface, a second end surface opposite to the first end surface, a connection pipe accommodating groove extending towards the direction of the second end surface from the first end surface along the axis ofthe base, and a gas flow channel provided with a plurality of branch flow channel parts. The liquid connection pipe is inserted into the connection pipe accommodating groove, partially bulged out of the first end surface, and provided with a pipe body and a flow distribution baffle connected into the pipe body. The flow distribution baffle is adjacent to an outlet end of the pipe body and definesa liquid channel with the pipe body. The flow confluence module is connected with the base, covers the first end surface, and surrounds the part bulged out of the first end surface, of the liquid connection pipe, so that a gas and a liquid are sprayed out after being subjected to flow confluence. By this, when the two-fluid nozzle is applied to a granulation procedure, the particle sizes of the granulated particles are much uniformly reduced, so that the yield of the small-particle-size particles is increased.

Description

technical field [0001] The invention relates to a two-fluid nozzle, in particular to a two-fluid nozzle for granulation. Background technique [0002] The manufacturing process of some existing materials must go through the spray granulation process, such as silicon carbon negative electrode materials for lithium batteries. Generally, a two-fluid nozzle is used in the spray granulation process to make the liquid slurry atomized by gas dispersion to form particles. Therefore, the spray efficiency of the nozzle for fluid formation is one of the important factors affecting the particle size of the granulation. [0003] However, the current two-fluid nozzle is difficult to mass-produce particles with a particle size below 10 μm, which cannot meet economic benefits, and there is still room for improvement. Contents of the invention [0004] One of the objectives of the present invention is to provide a two-fluid nozzle which is easier to form particles with smaller particle si...
