рнферии лопатки 6, которые образованы па« аами, выполненными вдоль образующих барабана . Четыре барабана 5 установлены в кор пусе 7, В верхней части корпуса расположен бункер 8 с металлическим порошком, соединенный непосредственно с четырьм  полост  ми Г, расположенными под бункером 8 и заполненными порошком Корпус 7 срдержит четыре цилиндричес- ких гнезда б, имеющих общую горизотгальгную ось и содержащих четьфе барабана 5, которые . отдепены друг от друга неподвижными дискамн 9, Барабаны 5 смонтированы на обшем горизонтальном валу 10, который приводитс  во вращение от шкива 11, Каждое из четырех цилиндрических гнезд 5 сообщаетс  с соответствующей полостью Г и выходной камерой 12, Камера .12 соединена с однот о коюда через трубу с соответствующим инжектором 2, а с другого конца через трубу 13 « с источником 14 сжатого газа, например ааота. Источник сжатого газа соединен с бункером 8 через трубу 15, что необходимо дл  уравновешивани  давлени  газа в устройстве. На каждой из груб 4 смонтирован манометр 3.6 дл  контрол  давлени  скорости потока газа. Устройство работает следующим образом . Привод т во вращение вал 10, барабаны 5 начинают вращатьс  по стрелке Д (см, фиг. 4), их лопатки 6 захватывают порощок в полост х Г и перемещают его в соответствующие выходные камеры 12, куда он вы гружаегс . Из источника 14 газ подают в камеры 12 дл  создани  в них взвешенного состо ни  порошка. Порошок во взвешенном состо нии поступает через трубы 4 в инжек торы 2, а из них - в плам  горелки 1. Ско рость подачи порошка измен ют в соответствии со скоростью вращени  барабана 5 и в соотаетствии с объемом лопаток 6. Образование пробки в инжекторе фиксируетс  манометром 16. При использовании предложенного устройства нанос5гг покрытие из алюминиевого порошка на стальную ленту шириной 340 мм, движущуюс  со скоростью 1,25 м/мин, при скорости пот-ока порошка через инжектор 2О г/мин и энергии плазмы 4О ква. Получают слой покрыти  одинаковой (90 мкм) толщины на всем прот жении ленты. Указанный эффект может быть достигнут и при несимметричном расположении инжекторов по отношению к пламени горелки. Данное устройство имеет преимущество при получении равномерных покрытий значительной толщины, состо щих из чистых металлов или металлических сплавов, наприMepj таких как Zn или , Формул р е т е н JJ   1.Устройство дл  металлизации изделий, содержащее приспособление дл  создани  пламени и равномерно расположенные вокруг этого приспособлени  ин секторы дл  подачи порошка в плам , отличающеес  тем, что, с целью повышени  равномерности .подачи порошка в плам , оно снабжено от дельными распределителыгыми приспособлени ми дл  подачи металлического порошка в соответствующие инжекторы. 2,Ус тройство по п. 1, о т л и ч а е е с   тем, что инжекторы установлены с возможностью .|{змеиени  их рассто ни  от продольной оси приспособлени  дл  создани  пламени. 3.Устройство по пп, 1 и 2, о т л и- чающеес   тем, что каждое из рас- пре&ёлительных приспособлений выполнено в виде барабана с лопатками, 4.Устройство по п. 3, о т л и ч а ю - щ е е с   тем, что барабаны смонтированы на общем валу, 5,Устройство по п. 4, о.т л и ч а ю - щ е е с   тем, что вал установлен горизонтально , 6,Устройство по пп, 1-5,, отличающеес  тем, что приспособление дл  создани  пламени выполнено в виде плазменной горелки. Источники информации, прин тые во внимание при экспертизе: 1. Патечт США № 3591759, кл. 219-76, 1971.The number of blades 6, which are formed by pasami, made along the forming drum. Four drums 5 are installed in the casing 7. In the upper part of the casing there is a bunker 8 with metal powder, connected directly to the four cavities G located under the bunker 8 and filled with powder. Casing 7 will hold four cylindrical slots b, having a common horizontal axis and containing four drum drum 5, which. Separated from each other by fixed plates 9, Drums 5 are mounted on a common horizontal shaft 10, which is driven into rotation from pulley 11. Each of the four cylindrical slots 5 communicates with the corresponding cavity G and the output chamber 12, Camera .12 is connected to one of the two a pipe with a corresponding injector 2, and from the other end through a pipe 13 "with a source 14 of compressed gas, for example aaota. The compressed gas source is connected to the hopper 8 via pipe 15, which is necessary to balance the gas pressure in the device. A gauge 3.6 is mounted on each of the coarse 4 to control the pressure of the gas flow rate. The device works as follows. The shaft 10 is driven into rotation, the drums 5 begin to rotate in the direction of arrow D (see Fig. 4), their paddles 6 capture the powder in cavity D and move it to the corresponding output chambers 12 where it is loaded. From source 14, gas is supplied to chambers 12 to create a suspended state of powder in them. The powder in a suspended state flows through the pipes 4 into the injectors 2, and from them into the burner flame 1. The powder feed rate is changed in accordance with the speed of rotation of the drum 5 and in accordance with the volume of the blades 6. The formation of a plug in the injector is recorded with a manometer 16. When using the proposed device nanoscall coating of aluminum powder on a steel strip 340 mm wide, moving at a speed of 1.25 m / min, at a rate of powder sweep through an injector of 2O g / min and plasma energy of 4O kva. A coating layer of the same thickness (90 µm) is obtained throughout the belt. This effect can also be achieved with an asymmetric arrangement of the injectors with respect to the burner flame. This device has the advantage of obtaining uniform coatings of considerable thickness, consisting of pure metals or metal alloys, for example Mepj such as Zn or, Formula JJ 1. A device for the metallization of products containing a device for creating a flame and evenly spaced around it devices and sectors for the supply of powder to the flame, characterized in that, in order to increase the uniformity of powder supply to the flame, it is equipped with separate distributors for the supply of metal powder in the appropriate injectors. 2, the device according to claim 1, so that the injectors are installed with the possibility. | {Snakes their distance from the longitudinal axis of the device to create a flame. 3. The device according to PP, 1 and 2, which is based on the fact that each of the distribution and ampli- fication devices is made in the form of a drum with vanes, 4. The device according to item 3, about which is Right with the fact that the drums are mounted on a common shaft, 5, The device according to p. 4, r.t.t is with the fact that the shaft is mounted horizontally, 6, The device according to PP, 1-5 characterized in that the device for creating a flame is made in the form of a plasma torch.
