Description
Technical field
The utility model relates to a kind of air jet system, especially a kind of gas shower nozzle.
Background technology
The flow process of cold-reduced sheet production comprises several operations such as pickling, cold rolling, slitting, cleaning, annealing, finishing, wherein in the process of pickling and cleaning, for impurity such as the iron rust of removing belt steel surface and greases, need to use number of chemical solution to react with it.And in the process of cold rolling and finishing,, need to add ROLLING OIL and smooth liquid in order to prevent to be with steel and roller bonding.Above-described solution or grease can influence following process attached to the surface of band steel, therefore it need be removed to keep the cleanliness factor of belt steel surface.Present domestic universal mode all is to use apparatus for drying that it is dried up volatilization; The structure of existing apparatus for drying as shown in Figure 1, mainly comprise airduct 21 and be arranged at shower nozzle 22 on the described airduct 21, has a direct current channel 23 on the described shower nozzle 22, described airduct 21 is used for being connected with high-pressure air source and transmits air-flow, and high pressure draught is dispensed on each shower nozzle 22, and then by shower nozzle 22 high pressure draught (being generally 0.5Mpa) is injected on the band steel for clearance and carries out cleaning, mode and airduct 21 secure fit of shower nozzle 22 to be spirally connected; The shower nozzle processing and manufacturing of above-mentioned apparatus for drying is simple, cost is low, owing to be to adopt the form that is spirally connected to cooperate with airduct, it is convenient therefore to change in addition; But above-mentioned shower nozzle also has following weak point: at first owing to only have a direct current channel on each shower nozzle, therefore the air-flow that ejects is point-like, skewness, and cleaning effect is limited; In addition, owing to be direct current channel and do not have noise-reducing structure, so air communication can produce very sharp-pointed noise (whistle of about 85-100 decibel) when crossing shower nozzle, and surrounding environment is caused noise pollution, and serious harm is staff's physical and mental health on every side.
Summary of the invention
The purpose of this utility model is to provide a kind of gas shower nozzle, with the big and air-flow problem of uneven distribution of shower nozzle noise that solves existing apparatus for drying.
In order to address the above problem, gas of the present utility model is with shower nozzle by the following technical solutions: a kind of gas shower nozzle, comprise the jet portion that is used for the connecting portion that is spirally connected with airduct and is sealedly attached to described connecting portion lower end, have on the described connecting portion and be used for the air-flow main channel that is connected with the airduct conducting, be provided with one-level bloop at least in the described air-flow main channel; Described bloop comprises noise elimination part, and described noise elimination part is sphere shape, is distributed with the pore that at least two air feed streams pass through on the noise elimination part; Described jet portion has the air flows passage that communicates with described air-flow main channel more than two.
The noise elimination part periphery of described bloop is provided with installs the edge, and the internal face upper edge of described air-flow main channel circumferentially is provided with corresponding convex annular edge, and the installation of described bloop is along cooperating with described convex edge block and being fixed by a gland.
Described air-flow main channel is up big and down small reducing passage, the pit that is distributed with sphere shape on the upper surface of described jet portion, and the import of described air flows passage is distributed in described each pit.
Has the arc transition face between the import of described air-flow main channel and the outlet.
Described each air flows passage is arranged in delegation.
Because gas of the present utility model is provided with bloop with shower nozzle in its air-flow main channel, and described bloop has a noise elimination part that is sphere shape, therefore the resonant frequency of the air-flow that passes through can be upset, destroy the air-flow resonator that forms in the mainstream channel, the noise (birdie) when reducing shower nozzle work greatly; In addition, at an end of described connecting portion jet portion is set, and two above air flows passages are set on described jet, therefore the air-flow by shower nozzle evenly can be disperseed, increase its purging scope.
Further, described bloop is fixed by gland, can be convenient for changing as required like this; Described air-flow main channel is set to up big and down small throat structure, and air-flow is changed from import to the flow direction between the outlet of air-flow main channel, further upsets the resonant frequency of air-flow, noise-decreasing; Adopting the cambered surface transition between the import of air-flow main channel and the outlet, also is in order further to upset the resonant frequency of air-flow, noise-decreasing; Described each air flows passage is arranged in a row, and can adapt to the width of band steel to be cleaned, increases the cleaning face that purges.
