Embodiment Construction
[0021] refer to figure 1 , a high-pressure water atomizing nozzle for iron and steel milling, comprising a nozzle housing 1, a nozzle core 2 with a central through hole and a spray head 3; the material of the nozzle housing 1 is 304 stainless steel, the nozzle core 2 and The material of the spray head is 9Cr18MoV. The lower end of the central through hole of the nozzle core 2 expands along the inclined plane to form a trumpet-shaped central hole. An annular groove is provided on the wall, and the nozzle housing 1 is tightly sleeved on the nozzle core 2, and an annular space is formed by the annular groove with the nozzle core 2. Preferably, the The upper end of the nozzle core 2 is provided with an L-shaped groove, the lower end edge is provided with a first boss, the inner wall of the upper end of the nozzle housing 1 is provided with a second boss for matching with the L-shaped groove, and the lower end surface is in line with the said L-shaped groove. The upper surface...

The invention provides a high pressure water atomization nozzle for steel pulverization. The high pressure water atomization nozzle comprises a nozzle shell, a nozzle wick and injection heads. The nozzle wick is provided with a center through hole. An annular groove is formed in the outer side wall of the nozzle wick. The nozzle wick is sleeved with the nozzle shell in a sealed mode. An annular space is formed between the nozzle shell and the nozzle wick through the annular groove. The injection heads are cylindrical. Each injection head is internally provided with an injection hole. An inner circle of injection head installation holes and an outer circle of injection head installation holes are arranged on the lower bottom face of the nozzle wick along the periphery of the center through hole of the nozzle wick. The bottoms of the injection head installation holes are provided with connecting through holes communicated with the annular space. The injection heads are arranged inside the injection hole installation holes. When the injection holes are blocked, the injection heads can be cleaned only after being disassembled, the whole nozzle wick does not need to be disassembled, and operation is easy and convenient; when the injection effect is affected due to the fact that the injection holes become large, only the injection heads need to be replaced, the whole nozzle wick does not need to be replaced, and the maintenance cost can be saved.
Description
technical field [0001] The invention relates to the technical field of hydraulic atomization metal powder production, in particular to a high-pressure water atomization nozzle for iron and steel powder production. Background technique [0002] In the production of powder by atomization, water atomization is one of the main production methods. On the one hand, because the atomization medium water is cheap and easy to obtain, on the other hand, from the perspective of atomization efficiency, the water atomization method performs better. [0003] Chinese patent 201320191663.7 discloses a high-pressure water atomizing nozzle, which includes a nozzle housing and a nozzle core. An annular groove is provided on the outer wall of the nozzle core, and two rings of water spray holes are provided on the lower bottom surface of the annular groove. The water outlet of the water spray hole faces the axis of the nozzle core; the nozzle housing and the nozzle core form a closed annular spa...
