Abstract

FIELD: powder metallurgy, apparatuses for powder production by smelts spraying, production of zinc, leas, aluminum and other metals powder in particular. SUBSTANCE: apparatus for metal powder production from smelt has body 1 with cylindrical cavity divided for inner ring type part 3 and outer ring-type part 2, each of which using hales 4 and 5 communicates with compressed air source ( not shown); mounted in body 1 tube 6 to feed smelt, which output end 7 is provided with jet joint made in the form of two connected with outer cavity 2 shifted one in respect to another truncated conical details 8 and 9 with angle of inclination to tube of 6 - 30 deg and connected with inner cavity 3 of air stream swirler 10 made in the form of cylindrical extension, on surface of which there are uniformly located air passing grooves 11, 12 and 13 located at angle of 30 deg to tube axis. Apparatus has cylindrical separating member 14 and two swirlers 15 and 16 with uniformly located at angle of 30 deg to tube axis grooves 17 and 18. In the case swirlers 16 and 15 are mounted before jet joint and swirler 15 is made in the form of disk fixed on separating member 14 and is located in outer cavity 2 and second swirler 16 is made in the form of cylindrical extension of bigger size, than cylindrical extension of swirler 10 of jet joint and is mounted in separating member 14 and is located in inner cavity 3. Hole 5 of body 1 for air feeding is located tangentially.. Auxiliary joint has body with nozzle 19 and confusor 20. In the case inlet hole 21 of nozzle 19 is conjugated with hole 22 to feed compressed air and inlet hole 23 of confusor 20 - with inlet 24 branch pipe 25 metal smelt feeding. EFFECT: simplified maintenance , decreased power consumption, increased productivity and quality of produced powders without increase of pressure and air consumption.

Изобретение относится к порошковой металлургии, более конкретно- к устройствам для производства порошков распылением расплавов и, в частности, может найти широкое применение при производстве порошков цинка, свинца, алюминия и других металлов. Цель изобретения - создание устройства, простого в обслуживании, не требующего потребления злектроэнергии, обеспечивающего высокие производительность, качество и ассортимент получаемых порошков без увеличения давления и расхода воздуха. Устройство для получения металлического порошка из расплава состоит из корпуса 1 с цилиндрической полостью, разделенной на внешнюю 2 и внутреннюю 3 кольцевые части, каждая из которых при помощи отверстий 4 и 5 сообщена с источником сжатого воздуха (не показан), установленную в корпусе 1 трубку 6 для подачи расплава, выходной конец которой 7 снабжен форсуночным узлом в виде двух связанных с внешней полостью 2 смещенных относительно друг друга усеченных конических деталей 8 и 9 с углом наклона к оси трубки 6 - 30° и связанных с внутренней полостью 3 завихрителя 10 воздушного потока в виде цилиндрической насадки, на поверхности которых под углом 30° к оси трубки выполнены равномерно расположенные пазы 11,12 и 13 для прохождения воздуха. Устройство снабжено цилиндрическим разделительным элементом 14 и двумя завихрителями 15 и 16 с равномерно расположенными под углом 30° к оси трубки 6 пазами 17 и 18, при этом завихрители 16 и 15 установлены перед форсуночным узлом и один из них 15 выполнен в виде диска, закрепленного на разделительном элементе 14, и расположен во внешней полости 2, а второй 16 выполнен в виде цилиндрической насадки большего размера, чем цилиндрическая насадка завихрителя 10 форсуночного узла, установлена в разделительном элементе 14 и размещена во внутренней полости 3. Отверстие 5 корпуса 1 для подвода сжатого воздуха расположено тангенциально. Дополнительный узел содержит корпус с соплом 19 и конфузором 20, причем входное отверстие 21 сопла 19 сопряжено с отверстием 22 подвода сжатого воздуха, а входное отверстие 23 конфузора 20 - с входным отверстием 24 патрубка 25 повода расплава металла.

The invention relates to powder metallurgy, and more particularly to a device for the production of powders by spraying melts and, in particular, can be widely used in the production of powders of zinc, lead, aluminum and other metals. The purpose of the invention is the creation of a device that is easy to maintain, does not require the consumption of electrical energy, providing high performance, quality and assortment of powders obtained without increasing pressure and air flow. A device for producing metal powder from a melt consists of a housing 1 with a cylindrical cavity divided into outer 2 and inner 3 annular parts, each of which is connected to a compressed air source (not shown) through holes 4 and 5, a tube 6 installed in the housing 1 for supplying a melt, the outlet end of which 7 is equipped with a nozzle assembly in the form of two truncated conical parts 8 and 9 connected to the outer cavity 2 and tilted to the tube axis 6-30 ° and connected to the inner cavity 3 s air vortex 10 in the form of a cylindrical nozzle, on the surface of which, at an angle of 30 ° to the tube axis, uniformly located grooves 11,12 and 13 for air passage are made. The device is equipped with a cylindrical separation element 14 and two swirls 15 and 16 with grooves 17 and 18 evenly spaced at an angle of 30 ° to the tube axis 6, while swirls 16 and 15 are installed in front of the nozzle assembly and one of them 15 is made in the form of a disk mounted on the separation element 14, and is located in the outer cavity 2, and the second 16 is made in the form of a cylindrical nozzle larger than the cylindrical nozzle of the swirl 10 of the nozzle assembly, is installed in the separation element 14 and placed in the inner cavity 3. O the bore 5 of the housing 1 for supplying compressed air is located tangentially. The additional assembly comprises a housing with a nozzle 19 and a confuser 20, the inlet 21 of the nozzle 19 being coupled to the compressed air inlet 22, and the inlet 23 of the confuser 20 to the inlet 24 of the nozzle 25 of the metal melt.
