Shape outer wind deflector stacks female cone ventilating duct in the outer wind deflector cavity of polygon.
The utility model is also characterized by:
There is gap between the outer wind deflector of polygon and female cone ventilating duct, gap width is stretched out not less than sprayer nozzle
Length.
It is fixed between the outer wind deflector of polygon and female cone ventilating duct by screw rod.
Female cone ventilating duct includes outer toroid flanged plate and core cone cylinder closed at both ends, the welding of outer toroid flanged plate inner ring
The one end for having core cone cylinder to be relatively large in diameter, the core cone cylinder other end are placed in the outer wind deflector of polygon.
The outer wind deflector of polygon includes wind deflector annulus flanged plate, and wind deflector annulus flanged plate inner ring is welded with internal for sky
Larger one end of conical baffle opening of chambers of the heart body, conical baffle outer ring are equidistantly welded with multiple vertical plates, core cone cylinder
Outer wall passes through wind deflector annulus flanged plate and is placed in the cavity of conical baffle.
Conical baffle is regular polygon conically shaped shape structure.
The beneficial effects of the utility model are:
A kind of welded type air ducting of the utility model, by the reasonable of wind deflector outside polygon and female cone ventilating duct
Design controls gas flow, so that spray head under the power-assisted of water conservancy diversion wind, sprays farther, is higher, area coverage is bigger, improves spray
Mist working efficiency realizes energy-efficient purpose.

Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of welded type air ducting of the utility model, as shown in Figure 1, including the outer wind-guiding of polygon of embedded with conical cavity
Plate stacks female cone ventilating duct in the outer wind deflector cavity of polygon.
There is gap between the outer wind deflector of polygon and female cone ventilating duct, gap width stretches out length not less than sprayer nozzle
Degree.
It is fixed between the outer wind deflector of polygon and female cone ventilating duct by screw rod.
As shown in Fig. 2, female cone ventilating duct includes outer toroid flanged plate 1 and core cone cylinder 2 closed at both ends, outer circle is around-France
Blue 1 inner ring of plate is welded with one end that core cone cylinder 2 is relatively large in diameter, and 2 other end of core cone cylinder is placed in the outer wind deflector of polygon.
As shown in figure 3, the outer wind deflector of polygon includes wind deflector annulus flanged plate 3, lap welding in wind deflector annulus flanged plate 3
Being connected to internal is that the conical baffle 4 of hollow cavity is open larger one end, and 4 outer ring of conical baffle is equidistantly welded with multiple vertical
Plate 5, the outer wall of core cone cylinder 2 pass through wind deflector annulus flanged plate 3 and are placed in the cavity of conical baffle 4.
Wind deflector annulus 3 structural schematic diagrams of flanged plate are as shown in Figure 4.
As shown in figure 5, conical baffle 4 is regular polygon conically shaped shape structure.
The effect of each section is as follows in a kind of welded type air ducting of the utility model:
The effect of outer toroid flanged plate 1 is: serving as welding tooling, clip lives core cone cylinder 2；Pacify simultaneously for female cone ventilating duct
Dress provides support.
Core cone cylinder 2: its outer wall is taper, can change the flow direction for being blown into air, flows air along its outer wall.
Wind deflector annulus flanged plate 3: serving as welding tooling, and clip lives conical baffle 4；It is simultaneously the outer wind deflector of polygon
Installation provides support；And each semicircle orifice on its outer can be arranged for spray head provides positioning datum.
Conical baffle 4: rear and front end is regular polygon, and centre is formed using gradient angled transition.The plate uses metal plate
After golden bending and molding, it is welded together for 3 groups with wind deflector annulus flanged plate.The air-flow produced by boasting from blower by the plate rectification after,
Flow direction is stablized without turbulent flow, sinuous flow.
A kind of welded type air ducting working principle of the utility model is as follows:
As shown in fig. 6, the spray head of spraying machine is set in use, the be open lesser one end of conical baffle 4 is connected blower
Between outer toroid flanged plate 1 and wind deflector annulus flanged plate 3, and the injection direction of nozzle along radius and deviates from the center of circle, blower
After opening, conical baffle 4 is blowed air into, the air-flow is empty along the annular between 2 outer wall of core cone cylinder and conical baffle 4
Between be displaced outwardly, the medicament that nozzle ejects uniformly sprays under the power-assisted effect of air-flow into surrounding space.
By the above-mentioned means, a kind of welded type air ducting of the utility model, by wind deflector outside polygon and inner circle
The rational design of ventilating duct is bored, gas flow is controlled, so that spray head under the power-assisted of water conservancy diversion wind, sprays farther, is higher, covering surface
Product is bigger, improves spray operations efficiency, realizes energy-efficient purpose.
