The airflow-stabilizing air knife mainly comprises a knife body base, air knife connection boards, air knife main boards, air knife cover boards and the like. Two air knife modules are installed on the knife body base by a certain angle; when the air knife device works, high pressure air is input from air inlet connectors of the knife body base, passes through an air path of an inner cavity of the knife body base, is output to connection board air guide grooves through air passing holes of the knife body base, then is output into air passing round holes of the air knife main boards through the connection board air guide grooves and is output from air knife edges through curve air guide grooves of the air knife main boards, so that air curtain walls with a certain angle and uniform and stable airflow are formed; and a copper wire soaked with molten tin moves in the crossed center direction of the air curtain walls along the center symmetry line of the two air knife modules, and the molten tin forms a thin tin coating uniform in thickness on the surface of a copper strip under the action of the air knife.
Description
Technical field
The present invention relates to a kind of air blowing class drying device, particularly relate to the molten stannum of butt welding belt surface during the painting process of tin of welding
Carry out blowing the air knife covered.
Technical background
Being coated with the crucial materials in the manufacture that stannum brazing band is photovoltaic industry equipment, the quality of welding quality is directly connected to photovoltaic apparatus
Assembly property superior, is particularly relevant to the utilization ratio of the photovoltaic apparatus energy and the service life of equipment.The making of welding
Journey generally comprises, and the calendering of raw material copper strips, anneals, is coated with the operations such as stannum, and being coated with stannum is important procedure therein.It is coated with the general work of stannum
It is calendering the copper strips annealed to be infiltrated in the stannum pond of fusing, draws it out again after a period of time as process, and with air knife pair
The uneven liquid tin blowing down its surface attachment drips.Air knife is particularly important to the control blowing down air-flow in the process, height to be obtained
Quality, high performance welding, the air-flow of air knife blowout, except wanting stannum unnecessary for copper strip surface to be dripped blowing, is also wanted to make
Copper strip surface forms that thickness is certain and uniform thin-walled tin layers.It is strong that this just requires that the air-flow blowing the blowout of stannum air knife forms certain air-flow
The lamellar air curtain wall of degree, and the stability in air curtain flow field to be ensured.
Air knife is a kind of knot screen conventional in industrial circle, it be widely used in glass, food and drink, printing, rubber,
The industry such as electronics finishing, five metals.Existing air knife is basically identical in know-why, is substantially and utilizes self inner chamber to set
The high pressure draught that air inlet disorder is unstable is converted into the pressure stability air curtain wall of air outlet by the wind-guiding path of determining putting spy.Utilize wind
Cutter can remove the various residual impurities on product facility or raw material surface such as easily and fast: dust, residual night, moisture etc..
Find that the drag characteristic of air knife is a pair conflicting body with the stability characteristic (quality) of flow velocity, for obtaining good flow velocity by research
Stablizing effect will sacrifice certain pressure energy, if reducing air knife gas-flow resistance the most also will sacrifice certain flow speed stability effect.This
Outward, air knife gas channel cross section should change slowly, avoids producing backflow, whirlpool as far as possible, allows the flow to be continued, releive
Regulation with control rather than rapid, strong throttling and obstruction, the adjustment of air-flow needs the regular hour upper and spatially
Process.
In actual commercial Application, the size of flow field wind speed, stability and uniformity that air knife air outlet produces are the most barely satisfactory,
And the resistance of air knife is excessive, adding the energy consumption of blower fan, these design unreasonable causing mainly due to the structure of air knife.
Want to obtain stability, uniformity and certain blast satisfactory air curtain wall, it is necessary to the overall structure of air intake cutter carries out excellent
Change and improve.
Summary of the invention
Goal of the invention:
The technical problem to be solved in the present invention is, uneven for above-mentioned drying air knife air outlet flow field wind speed, and stability is imitated
The poorest, and the problem such as the windage of air knife is excessive, the air knife of a kind of new structure is proposed, the flow field that the air outlet of this air knife produces
Wind speed size, stability and uniformity are attained by preferable effect, and the resistance of air knife subtracts under equal air outlet blast
Little.
Technical scheme:
For realizing function above, apparatus of the present invention mainly include blade base, air knife connecting plate, air knife mainboard, air knife cover plate
Deng critical component.Blade base plate acts primarily as installation fixation, when being applied to be coated with stannum device, and the air knife peace by blade base
Dress fixing hole is installed on above melting tin tank, and blade chassis interior there is also current path for air-flow guiding simultaneously；Air knife connects
Plate is close to the groove of blade seat and is installed, and the connecting plate air slot above it is just to the base air passing hole on blade base, for gas
The guiding on road, plate there is also two unthreaded holes owing to installing fixing using；Air knife mainboard is close to air knife connecting plate and is installed, foreign steamer
Exterior feature overlaps with it；The superiors are air knife cover plate, and air knife mainboard is close to by air knife cover plate；Final utilization bolt is by air knife cover plate, wind
Cutter mainboard, air knife connecting plate are tightly fastened on air knife base, it should be noted that air knife cover plate, air knife mainboard, air knife are even
Fishplate bar and its face that contacts with each other of air knife base are all through the special technique that polishes, and contact surface is the most smooth so that it is the tightest
Close fit, it is ensured that the air-tightness that air blade device is good.
Two unthreaded holes on air knife mainboard are used for disposing fixing, the circular port of air knife mainboard air passing hole and air knife connecting plate air slot
Being connected, it is also interconnected with the curve air slot on air knife mainboard, guides air-flow and buffers；On air knife mainboard
Curve air slot be the conflicting relation considered between the stable and uniform of exit flow and air knife windage and be optimized and set
The structure of meter.
Two unthreaded holes on air knife connecting plate are for connecting fixing hole, and connecting plate air slot thereon has not at the tow sides of plate
The same structure, the one side of circular configuration and air knife mainboard to cross gas circular hole in mating connection, at the bottom of the one side of elongated circular groove and blade
The groove fit of seat connects, and elongated circular groove is close to the top of blade plinth air flow outlet, and air-flow can be entered by elongated circular groove structure
Row buffering current stabilization.
In device, two air knife modules are the most angled is arranged on blade base, and when device works, gases at high pressure are from blade
The air inlet input of base, through the gas circuit of the internal cavity of blade base, exports rebound from the air passing hole of blade base and leads
In air drain, then being input in the gas circular hole excessively of air knife mainboard via transition plate air slot, last gas is through the curve of inducing QI mainboard
Air slot is exported by the air knife edge of a knife, is formed the most angled, the air curtain wall that air-flow is uniform and stable.
Beneficial effect:
For ensureing stability and the uniformity of the air knife air-flow of output, ensure to reduce as far as possible the windage of air knife, the present invention simultaneously
Device have employed a kind of particular curve air-flow guide groove through optimizing so that the air curtain wall that air knife is ultimately formed it is to have reached
Satisfied effect.
