Scope.
As shown in Fig. 1 ~ 5, a kind of circular air knife, including upper shell 1 and lower house 2, after upper shell 1 and lower house 2 cover,
The two is internally formed the annular housing 3 that supply stream passes through, the circle that the two outside formation is worn for the circular welding of tin plating completion
Die hole 4；Wherein, die hole 4 is coaxially disposed with annular housing 3, positioned at upper shell 1 and lower house 2 in the side wall of die hole 4
Seam crossing is provided with out vane 5, and the air-flow in annular housing 3 reaches circular welding surrounding through going out vane 5.
Wherein, the section shape of annular housing 3 radially is polymorphic structure, and polymorphic structure is included positioned at outside and close
The rectangular configuration of inlet end 6, and be connected and close to the air-out passage for going out the side of vane 5 with rectangular configuration；Air-out passage by
Closely go out on the direction of vane 5 and be highly gradually reduced, gathering is played a part of to air-flow, it is not closed by its end to go out vane 5
Gap is formed；In order to change the air-out direction for vane 5, air-out passage end is provided with bending section 6, and bending section 6 is used to change
Go out the air-out direction of vane 5；In the present embodiment, bending section 6 causes the transmission direction of air-out direction and circular welding to be oppositely arranged,
So that gone out tin that vane 5 blows off to not processed circular welding surface flow.
In order to ensure the stability of air-flow, the first deflector 7 of annular is provided with annular housing 3, the first deflector 7 connects
The both ends of the surface that annular housing 3 is located on axial direction are connect, and annular housing 3 is divided into outer chamber 31 and inner chamber body, and are passed through
Inner chamber body and the UNICOM of outer chamber 31, inlet end 6 are connected by the air vent set thereon with outer chamber 31, go out vane 5 and inner chamber body
Connection；Wherein, because comparatively density is larger close to the air quantity of the side of inlet end 6, in order to ensure the uniformity of air quantity, first
The air vent density of setting of deflector 7 gradually increases on the direction away from inlet end 6, and the setting of the first deflector 7 to pass through
The air-flow of the Relatively centralized of the entrance of inlet end 6 is crossed under the shock of the first deflector 7, and the guide functions of air vent are had
Effect is disperseed.
In order to reduce the centrality of air inlet, circular air knife is located at its radial direction and is provided at both ends with two inlet ends 6, outer chamber 31
It is interior perpendicular to two place diameters of inlet end 6 in the radial direction be provided at both ends with two sealing baffles 8, for by outer chamber 31
Independent left and right cavity is divided into, the setting of sealing baffle 8 causes air-flow to add collision during scattered, and needs to dissipate
The space of cloth is effectively reduced, and is more beneficial for the dispersed of air-flow.
The second deflector 9 is additionally provided with inner chamber body, the second deflector 9 connection annular housing 3 is located on axial direction
Both ends of the surface, for inner chamber body to be divided into diversion cavity 32a and air-out chamber 32b from outside to inside；Diversion cavity 32a and air-out chamber 32b
By the air vent UNICOM on the second deflector 9, and air vent is uniformly distributed on the second deflector 9, the second deflector 9
The further uniformity for adding air-flow of setting because relatively uniform into the air-flow in diversion cavity 32a, therefore thereon
The air vent of setting is uniformly distributed, and reduces its difficulty of processing.
By the form of annular air in the present invention, carried out to wearing its tin plating circular welding of completing gone out in vane 5
Processing, it is uniform for ensure that the stress of circular welding in circumferential direction, so as to which its good centering be effectively ensured, is passed through
Stable air-flow can carry out integer again to tin coating, by controlling the big I of air quantity to adjust required thickness of coating
Section, ensures that its thickness meets design requirement, and the tin coating thickness after being handled by circular air knife is uniform and surface is smooth, effectively
The use quality and presentation quality of product are improved, avoids the influence to the generated energy of photovoltaic module, more use value.
