Description
Technical Field
The utility model relates to a coating equipment technical field, specifically speaking relates to a U-shaped inner tube type reaction coating film gas distribution device.
Background
In recent years, the demand of the reaction coating industry is higher and higher, and the reaction coating needs to be realized by that aluminum vapor reacts with other gases in a reasonable proportion and then is attached to a film. The existing coating equipment has the problem of uneven reaction caused by uneven distribution of aluminum vapor. At present, some coating equipment adopts a labyrinth gas distribution device, the labyrinth gas distribution device adopts an assembly mode that two plates are buckled, the processing technology is complex, in addition, in the practical use, because evaporation aluminizing generates a large amount of radiant heat, the two plates of the labyrinth gas distribution device can be seriously deformed due to uneven heating, and the gas supply is finally influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a subtend inner tube gas distribution device for reaction coating, solve above technical problem.
In order to solve the above problems, the utility model adopts the following technical scheme:
the utility model provides a U-shaped inner tube type reaction coating film gas distribution device which characterized in that: comprises an outer sleeve and an inner tube assembled in the outer sleeve; two ports of the outer sleeve are respectively and fixedly provided with an outer pipe plug; the inner pipe is in a U shape or is equivalent to a U-shaped structure, one end of the inner pipe penetrates through one outer pipe plug and extends out of the outer sleeve, and is fixedly provided with an air inlet nozzle which is connected with an air supply pipeline; a plurality of outer pipe air outlet holes are uniformly formed in the pipe wall of the outer sleeve along the axial direction; and a plurality of inner pipe air outlet holes are uniformly formed in the pipe wall of the inner pipe along the axial direction.
Preferably, the outer tube air outlet holes and the inner tube air outlet holes are arranged in a staggered mode, and each inner tube air outlet hole is formed in the inner side tube wall of the inner tube.
Preferably, the inner port of the inner pipe is closed or fixed with an inner pipe plug.
Has the advantages that: compared with the prior art, the utility model adopts a sleeve type structure, has simple structure and convenient manufacture, the outer sleeve and the U-shaped or U-shaped inner tube are respectively provided with the staggered air outlet holes, the gas enters the inner tube (the U-shaped structure of the inner tube enables the gas pressure to be uniform in the left and right width directions), enters the inner cavity of the outer sleeve through the air outlet holes on the inner tube and then is uniformly mixed, and then is discharged through the air outlet holes on the outer sleeve, thereby achieving the purpose of uniformly discharging air, realizing the uniformity of coating and improving the quality of coating products; meanwhile, the inner pipe is provided with a telescopic space, and can stably supply air after being heated, expanded and extended.
