Abstract
The utility model relates to a component structure of metal powder manufacturing equipment, in particular to a high pressure water atomized composite nozzle used in the process of manufacturing metal powder by means of water atomization. The composite nozzle comprises a seat body, wherein a metal liquid channel is arranged in the centre of the seat body; a primary atomizing nozzle is arranged at the periphery of the metal liquid channel, forming a conical water curtain; four secondary atomizing nozzles are arranged at the periphery of the primary atomizing nozzle, are opposite to one another two by two and are arrayed in a crossed way; water flow ejected by each secondary atomizing nozzle presents the shape of a fan plane, the fan plane shaped water flows ejected by each pair of opposite secondary atomizing nozzles are intersected to form a V-shaped water curtain located at the periphery of the conical water curtain, and straight lines where crossing angles of the two V-shaped water curtains formed by the two pairs of secondary atomizing nozzles are located are vertical to each other. As the structure of secondary atomization is adopted, the high pressure water atomized composite nozzle can be more easily used for forming the metal powder with superfine tissues and micro-cracks on the surfaces of particles.
Description
Technical field
The utility model relates to a kind of modular construction of metal dust manufacturing equipment, specifically is a kind of hydraulic atomized combining nozzle that uses in water atomization method manufacturing metal dust process.
Background technology
Water atomization is one of important method of preparation metal dust, the powder by atomization technology develops towards fine, hypoxemia direction in recent years, particularly the metal powder injection molded technology (MIM) that has grown up since the eighties in 20th century has driven the wilderness demand to refining metallic powder.
For water atomization plant, technical scheme with Chinese patent 200420089000.5 is an example, it adopts ring-type restraint-type atomizer, just can obtain higher fine powder rate at atomizing pressure 10～12Mpa, atomizing characteristics such as better results, but because its structural limitations can't realize (〉 80MPa) hydraulic atomized powder process requirement.Chinese patent 00247583.9 has also proposed hydraulic atomized nozzle, and this nozzle is a kind of circumferential weld type water atomizing nozzle, the production of granularity powder in the middle of only closing, the incompatible metal dust of producing injection moulding.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of hydraulic atomized combining nozzle that institutional framework is fine, can be used for making metal powder injection molded required powder that obtains is provided.
Hydraulic atomized combining nozzle of the present utility model includes the pedestal of an annular, and the pedestal center is provided with the molten metal passage that feed flow attitude metal flow passes through; Be equipped with the primary atomization nozzle of arranging along circumference in molten metal passage outer periphery, the injection water direction of all primary atomization nozzles is poly-to be handed on one point, thereby can form coniform water curtain, the primary atomization nozzle is communicated with outside water system by the water channel in the pedestal; Be provided with four secondary-atomizing nozzles in the primary atomization nozzle periphery, four secondary-atomizing nozzles are relative in twos, are cross and arrange, and the secondary-atomizing nozzle also is communicated with outside water system by the water channel in the pedestal; The current of each secondary-atomizing nozzle ejection are the fan-shaped plan shape, each fan-shaped plan shape current to relative secondary-atomizing nozzle ejection intersects V-arrangement water curtain of formation, the V-arrangement water curtain is positioned at the periphery of above-mentioned coniform water curtain, and the straight line at the angle of cut place of two V-arrangement water curtains of two pairs of secondary-atomizing nozzle spray formation is vertical mutually.
Water channel that is communicated with the primary atomization nozzle and the water channel that is communicated with the secondary-atomizing nozzle are independent separately.
The beneficial effects of the utility model are embodied in: 1, owing to adopt the structure of twice atomizing, make water atomization make that metal liquid stream can be torn more fully, cool off in the metal dust process, be easier to the metal dust that the formative tissue structure is fine, particle surface has micro-crack, be specially adapted to the manufacturing of the heat pipe capillary structure of inner wall of part last sintered type; 2, double-level atomizing nozzle can have separately independently water channel, can regulate expulsion pressure respectively, helps forming various process conditions, adapts to the manufacturing of different metal dusts.
