Description
Przedmiotem wynalazku jest podajnik dostarczajacy w sposób ciagly proszek przy napawaniu lukowym.The subject of the invention is a feeder that continuously delivers powder in an arc-welding.
W dotychczasowych rozwiazaniach podawania proszków wykorzystywalo sie zjawisko zasysania proszku przy przeplywie gazu o okreslonym cisnieniu. Rozwiazania takie wymagaly stosowania proszków o scisle okre¬ slonym ksztalcie i wymiarach poszczególnych ziarenek.In the previous solutions for the administration of powders, the phenomenon of powder suction has been used at the flow of gas with a specific pressure. Such solutions required the use of powders of a strictly defined nature the salty shape and dimensions of individual grains.
Celem wynalazku jest mozliwosc podawania proszków metalicznych, których ziarenka róznia sie ksztaltem i wymiarami. Cel ten zostal osiagniety poprzez wykorzystanie zjawiska fluidyzacji proszku przez strumien gazu nosnego. Skonstruowanie podajnika umozliwia bezposrednie wykorzystanie do napawania utwardzajacego np. metoda MIG mielonych zelazostopów bez koniecznego w starych rozwiazaniach ich topnienia i rozpylania.The object of the invention is to be able to administer metallic powders, the grains of which differ in shape and dimensions. This aim was achieved by using the phenomenon of powder fluidization by the gas stream carrier. The design of the feeder allows direct use for hardfacing, e.g. MIG method of ground iron alloys without melting and spraying, which was necessary in old solutions.
Podajnik wedlug wynalazku posiada zbiornik proszku zakonczony króccem wkreconym w dysze osadzona w korpusie, fluidyzator oraz rurke doprowadzajaca zfluidyzowany proszek do zasypnika, przy czym fluidyzator sklada sie z rurki zamknietej siatka, umieszczony jest w korpusie i umocowany nakretka.According to the invention, the feeder has a powder reservoir with a stub screwed into the nozzles in the body, a fluidizer and a tube feeding the fluidized powder to the hopper, the fluidizer it consists of a tube closed with a net, is placed in the body and fixed with a nut.
Przedmiot wynalazku przedstawiony jest w przykladzie wykonania na rysunku, na którym fig. 1 obrazuje wzajemna wspólprace podajnika proszku i palnika do napawania, natomiast fig. 2 konstrukcje podajnika pro¬ szku.The subject of the invention is presented in an exemplary embodiment in the drawing in which Fig. 1 shows mutual cooperation of the powder feeder and the surfacing torch, while Fig. 2 shows the construction of the feeder schku.
Zbiornik proszku 5, zakonczony króccem, wkrecany jest w wymienna dysze 2, dobierana zaleznie od wymaganej wydajnosci podajnika i ziarnistosci proszku. Dysza 2 wkrecana jest w korpus 1. Króciec 9 doprowa¬ dzajacy gaz nosny, zakonczony fluidyzatorem: rurka 3 zamknieta siatka 4 mocowany jest z korpusem 1 na¬ kretka 7. Rurka 6 doprowadzajaca zfluidyzowany proszek do zasypnika 8 mocowana jest z korpusem 1 na¬ kretka 7.The powder container 5, ended with a stub pipe, is screwed into the replaceable nozzles 2, selected depending on required feeder capacity and powder granularity. Nozzle 2 is screwed into body 1. Spigot 9 is supplied carrying gas, terminated with a fluidizer: tube 3 closed mesh 4 is attached to the body 1 on kretka 7. The tube 6 carrying the fluidized powder to the hopper 8 is attached to the body 1 on mole 7.
Proszek metaliczny znajdujacy sie w zbiorniku 5 pod dzialaniem sily ciezkosci opada na siatke 4 stanowia¬ cy wylot fluidyzatora. W momencie doplywu gazu przez króciec 9 do fluidyzatora pod siatka 4 wytwarza sie minimalne nadcisnienie i wystepuje efekt fluidyzacji: proszek-cialo stale uzyksuje wlasnosci cieczy. Proszek splywa po siatce 4 i unoszony jest poprzez rurke 6 do zasypnika 8 przez gaz nosny uchodzacy z fluidyzatora. Na2 97 848 miejsce ubywajacego z siatki 4 w sposób ciagly proszku opada ciaglym strumieniem proszek ze zbiornika 5, Wydajnosc podajnika mozna regulowac poprzez zmiane natezenia przeplywu gazu nosnego oraz przez wymiane dyszy 2.The metallic powder contained in the tank 5 falls on the mesh 4 under the action of gravity. fluidizer outlet. As the gas flows through the nozzle 9 to the fluidizer, the mesh 4 is formed minimum overpressure and fluidization effect occurs: the powder-body constantly acquires the properties of a liquid. Powder it flows down the mesh 4 and is lifted through the tube 6 to the hopper 8 by the carrier gas escaping from the fluidizer. Na2 97 848 the place of the wastewater from the mesh 4, the powder from the reservoir 5 continuously falls in a continuous stream, The capacity of the feeder can be adjusted by changing the flow rate of the carrier gas and by exchange nozzle 2.
Podajnik moze byc zastosowany wraz z palnikiem do napawania powierzchni elementów zuzytych lub nowych.The feeder can be used together with a burner for surfacing worn elements or new.
