Description

Przedmiotem wynalazku jest urzadzenie do do¬ prowadzania proszku- metalu do palnika plazmo¬ wego, w celu wytwarzania powlok metalowych.The subject of the invention is a device for leading the powder-metal to the plasma torch for the manufacture of metal coatings.

Znane jest rozpylanie proszku czystego metalu, lub stopu na powierzchnie metalowa, na przyklad blache, w celu utworzenia powloki przy uzyciu palnika plazmowego, w którego plomien wprowa¬ dza sie proszek poprzez przewód, na którego kon¬ cu znajduje sie wtryskiwacz.It is known to spray pure metal powder, or an alloy on a metal surface, for example sheet to create a shell using a plasma torch into which the flame is inserted the powder is passed through the conduit on which the end cu is located in the injector.

Obecnie palniki plazmowe zaopatrzone sa tylko w jeden wtryskiwacz. Wskutek trtidnosci w regu¬ larnym zasilaniu wtryskiwacza, poniewaz przewody transportujace proszek zanieczyszczaja sie i czasa¬ mi zatykaja sie nawet calkowicie, otrzymane po¬ wloki sa nierównomierne i nie równej grubosci.Currently, plasma torches are supplied only into one injector. As a rule of thumb, lar supply of the injector because the wires transporting the powder becomes contaminated and time me clog even completely, received after- the trawls are uneven and not of equal thickness.

Celem wynalazku jest wyeliminowanie niedo¬ godnosci znanych rozwiazan oraz opracowanie urzadzenia, którego zastosowanie umozliwi uzyska¬ nie pokryc calkowicie regularnych i równomier¬ nych.The object of the invention is to eliminate the shortcomings dignity of known solutions and elaboration equipment, the use of which will enable to obtain not cover completely regular and even all.

Cel ten osiagnieto przez zaopatrzenie urzadzenia w kilka wtryskiwaczy proszku metalu, umieszczo¬ nych na obwodzie koncówki palnika plazmowego, z których kazdy polaczony jest z rozdzielaczem ro¬ tacyjnym w postaci bebna z rowkami usytuowany¬ mi wzdluz tworzacych, przy czym katy zawarte miedzy osiami dwóch kolejnych wtryskiwaczy sa równe.This goal was achieved by equipping the device in several metal powder injectors, placed on the circumference of the tip of the plasma torch, each of which is connected to a rotor a drum with grooves located ¬ along forming me, with angles included between the axes of two consecutive injectors are equal.

Liczba wtryskiwaczy moze byc parzysta. Sa one wtedy umieszczone symetrycznie w stosunku do koncówki palnika plazmowego.The number of injectors may be even. They are then placed symmetrically with respect to plasma torch tips.

Liczba rozpylaczy moze byc równiez nieparzysta i wtedy rozpylacze sa rozmieszczone asymetrycz¬ nie w stosunku do koncówki palnika. Koncówki wtryskiwaczy sa osadzone przesuwnie w zmien¬ nych odleglosciach od zródla plomienia. Rozdzie¬ lacze rotacyjne sa umieszczone obok siebie na tym samym walku napedowym wyposazanym w jederv naped.The number of nozzles can also be odd and then the nozzles are arranged asymmetrically not in relation to the burner tip. Tips the injectors are slidably mounted in the variable different distances from the source of the flame. Split rotating links are placed side by side on this same drive shaft equipped with jederv drive.

W korpusie 1 (fig. 1 i 2) o duzej wytrzymalosci, umieszczony jest zasobnik 14 proszku polaczony bezposrednio z czterema wglebieniami 2 tworza¬ cymi czerpak, wydrazonymi w korpusie 1 pod za¬ sobnikiem. Wglebienia 2 sa wypelnione proszkiem.In the body 1 (fig. 1 and 2) with high strength, there is a combined powder hopper 14 directly with the four cavities 2 forming of the bucket, expressed in the body 1 under the tab Saturday. 2 dimples are filled with powder.

W korpusie 1 wykonane sa równiez cztery gniaz¬ da cylindryczne 3 o wspólnej osi poziomej. W kaz¬ dym z gniazd 3 znajduje sie jeden rozdzielacz ro¬ tacyjny 4 w postaci bebna cylindrycznego posiada¬ jacego na obwodzie rowki 5 usytuowane wzdluz 104 057104 057 3 4 tworzacych. Cztery rozdzielacze oddzielone od sie¬ bie przez tarcze 4a sa umieszczone obok siebie na wspólnym walku 6 wprowadzanym w ruch obro¬ towy za pomoca kola pasowego 6a. Gniazdo cylin¬ dryczne kazdego rozdzielacza jest bezposrednio po¬ laczone z jednej strony z odpowiadajacym wgle¬ bieniem 2 i z drugiej strony z komora przelewowa lt która .sluzy równiez dla wprowadzania proszku w stan zawieszenia. Kazdy rozdzielacz rotacyjny 4 przenika czescia swego obwodu z jednej strony we wglebienie 2 i z drugiej strony w komore przele¬ wowa 7. Kazdemu rozdzielaczowi 4 odpowiada je¬ dno wglebienie 2 i jedna komora 7, w której pro¬ szek wprowadza sie w stan zawieszenia.There are also four slots in the body 1 will give cylindrical 3 with a common horizontal axis. In Kazakhstan the smoke from the nests 3 is provided with one rotor 4 in the form of a cylindrical drum has along the perimeter, grooves 5 located along the length 104 057 104 057 3 4 forming. Four distributors separate from the network by the discs 4a are placed next to each other on a common roller 6 driven by rotation using a pulley 6a. Cylinder socket each manifold is directly connected bonded on one side with matching carbon beam 2 and on the other side from the overflow chamber lt which is also used to introduce the powder in limbo. Each Rotary Manifold 4 penetrates part of its circumference on one side of the we hollow 2 and on the other side in the chamber vw 7. Each divider 4 corresponds to it the bottom is a hollow 2 and one chamber 7 in which the the shek goes into limbo.

Gdy rozdzielacze 4 sa wprowadzane w ruch w kierunku strzalki X, rowki na ich obwodzie po¬ bieraja proszek z wglebien 2, transportuja i wsy¬ puja go do komór przelewowych 7. Komory sa po¬ laczone z jednej strony przez przewód 8 z odpo¬ wiadajacym wtryskiwaczem 9, a z drugiej strony przez przewód 10 ze zródlem 11 sprezonego gazu, na przyklad azotu. W ten sposób proszek metalu wprowadzony do komór 7, jest wprowadzony w stan zawieszenia w gazie i nastepnie do wtryski¬ waczy 9, których koncówki 12 sa umieszczone blis¬ ko plomienia plazmowego 13 (fig. 3 i 4). Zródlo gazu 11 polaczone z komorami przelewowymi ma równiez polaczenie z zasobnikiem 14 poprzez prze¬ wód 15 dla wyrównania cisnienia.When the 4 manifolds are put into motion at direction of the arrow X, the grooves on their circumference are they take the powder from the soil 2, transport it and inject it he put it into the overflow chambers 7. The chambers are empty connected on one side by a line 8 with resp with injector 9 and on the other side through the line 10 with a source 11 of compressed gas, for example nitrogen. This is how metal powder introduced into chambers 7, is introduced in suspended in gas and then to injection plugs 9, the ends 12 of which are located close to the plasma flame 13 (Figs. 3 and 4). Source gas 11 connected to the overflow chambers ma also a connection to the reservoir 14 via a switch of water 15 for pressure equalization.

Na przykladzie uwidocznionym na fig. 3 i 4, pal¬ nik plazmowy 17 zaopatrzony jest w cztery wtrys¬ kiwacze 9 umieszczone na. wsporniku 9a przymo*- cowanym do koncowej czesci palnika plazmowego.In the example shown in Figs. 3 and 4, flame the plasma generator 17 is provided with four injectors 9 nods placed on. bracket 9a adjo * - attached to the end of the plasma torch.

Wtryskiwacze 9 sa rozmieszczone symetrycznie w stosunku do plomienia 13, to znaczy sa parami przeciwlegle lub tworza wzajemnie kat 90°. Kon¬ cówki 12 wtryskiwaczy 9 sa usytuowane w tej sa¬ mej odleglosci od zródla plomienia, gdy wszystkie wtryskiwacze podaja proszek metalu tego samego rodzaju. W przypadku stosowania metali róznego rodzaju podawanych przez rózne wtryskiwacze, ich koncówki osadzone przestawnie, sa wówczas umieszczone w róznych odleglosciach od zródla .plomienia.The injectors 9 are arranged symmetrically in relation to flame 13, that is, they are in pairs opposite or mutually forming a 90 ° angle. Con¬ The injector pins 12 9 are aligned with each other my distance from the source of flame, when all the injectors feed the powder of the metal of the same kind. When using different metals the type provided by the various injectors, their the ends are staggered, they are then placed at different distances from the source . diplomas.

Gaz uzyty jako srodek dla wprowadzenia prosz¬ ku w stan zawieszenia sluzy równiez jako srodek transportu proszku. Ilosc proszku uzytego w jed¬ nostce czasu zmienia sie w zaleznosci od predkosci obrotowej rozdzielaczy rotacyjnych i w zaleznosci od objetosci rowków wykonanych na powierzchni rozdzielaczy.The gas used as a medium for the introduction of the powder the suspended state also serves as a measure powder transport. The amount of powder used in one unit The difficulty of time varies according to the speed rotary and rotary distributors according to on the volume of grooves made on the surface distributors.

W kazdym przewodzie 8 doprowadzajacym pro¬ szek do wtryskiwaczy 9 jest umieszczony mano¬ metr 16 (fig. 2) pozwalajacy kontrolowac cisnienie i ilosc gazu przeplywajacego w jednostce czasu, wskazujacy ewentualne zatkanie któregos z rozpy¬ laczy.In each line 8 leading to pro? the injector pin 9 is fitted with a mano meter 16 (fig. 2) to control the pressure and the amount of gas flowing per unit time, indicating a possible blockage of any spray combines.
