Detailed description of the invention
The present invention is by changing air nozzle structure, thus adopt straight-through section make wind by time form equal nip, thereby guarantee the stability of final air outlet wind speed.Below by describing technology contents of the present utility model, structural feature in detail, being realized object and effect, in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 4, the utility model relates to the special tuyere of a kind of coating dryer, and it comprises air compartment 40 and straight-through section 41; Described straight-through section of 41 one end are connected with air compartment 40, and the other end sets out air port.
Thus, be different from air outlet in original tuyere and adopt the mode of disperseing air-out, owing to being straight-through section before tuyere air outlet, can well guide fluid to pass through one section of smooth passage, in this straight-through section, do not exist the unexpected size variation of ventilation-sectional area therefore can not cause eddy current yet, can, at the equal nip of straight-through section 41 interior formation, guarantee the stability of wind speed when final wind blows out from air outlet on the contrary.After tested, equally in the time that wind speed average speed is 8m/min, adopt after the utility model structure, the wind speed deviation of air outlet is only at ± 0.3m/min.Thus, in the time that this tuyere is applied in coating dryer, make wind that tuyere blows out form thrust upwards to foil stable because the wind speed after all pressing is stable, foil there will not be jitter phenomenon in oven interior, has avoided the inconsistent problem appearance of coating thin and thick.
Embodiment mono-:
In said structure, air compartment 40 cross sections of tuyere are isosceles triangle, and described straight-through section is connected on isosceles triangle summit.As general selection, the wind speed that the shape of air compartment 40 can not blow out wind to final air outlet exerts an influence.If but air compartment is designed to isosceles triangle, not only can make fluid enter in the air compartment 40 of tuyere has better mobility, and makes air compartment 40 structures be convenient to produce.
Embodiment bis-:
In said structure, described straight-through segment length is not less than 20mm.By above-mentioned visible, straight-through section 41 plays a part crucial in tuyere, and all presses effect in order to ensure it, and the length of straight-through section should be not less than 20mm.Just strengthen identical to the stability principle of outgoing shell as gun barrel, barrel length in theory, therefore longer straight-through section can be played better proportionality action to the wind of flowing through, but considers actual product applied environment, through experiment repeatedly, best, this straight-through segment length 20-28mm is best.
Embodiment tri-:
In order to ensure wind speed preferably, the internal diameter of straight-through section should design at 3-5mm as best.
Embodiment tetra-:
Best, protection convex edge 42 is set air outlet one end of above-mentioned straight-through section 41, extend along horizontal direction protection convex edge 42, and it can be directly forms for straight-through section 41 extensions outwards turn down.Increase when this protection convex edge 42 can make tuyere be applied to coating dryer the foil entering in drying tunnel is played to a protective effect, place tuyere and damage foil.
As shown in Figure 2, the utility model also provides a kind of coating dryer, it comprises shell body 1, in shell body 1, be provided with the drying tunnel that can pass through for foil 50, be respectively arranged with ipper air chamber 2 and lower air chamber 3 in drying tunnel upper and lower, in described ipper air chamber 2 and/or lower air chamber 3, adopt the tuyere of feature described above.Herein, according to foil 50 uniformities of drying and heating need can will separately tuyere be applied in ipper air chamber 2 as upper tuyere 4, lower air chamber 3 as lower tuyere 5, upper tuyere 4 and the lower tuyere 5 of also can be in the wind chamber 2, lower air chamber 3 all adopt this structure.Thereby be different from air outlet in original tuyere and adopt the mode of disperseing air-out, by being straight-through section before tuyere air outlet, air-out is risen and is guided through one section of smooth passage, owing to not existing the unexpected size variation of ventilation-sectional area therefore can not cause eddy current in this straight-through section, straight-through section 41 interior wind energies form equal nip on the contrary, have guaranteed the stability of wind speed when final wind blows out from air outlet.After tested, equally in the time that wind speed average speed is 8m/min, adopt after the utility model structure, the wind speed deviation of air outlet is only at ± 0.3m/min.Thus, in the time that this tuyere is applied in coating dryer, make wind that tuyere blows out form thrust upwards to foil stable because the wind speed after all pressing is stable, foil there will not be jitter phenomenon in oven interior, has avoided the inconsistent problem appearance of coating thin and thick.
Embodiment five:
In said structure, the air compartment 40 of tuyere 60 is connected with ipper air chamber 2 or lower air chamber 3; Air outlet of its straight-through section 41 is towards drying tunnel direction, thereby guarantees that air-out directly can blow in the foil 50 in drying tunnel.
Embodiment six:
In said structure, the chamber 2 of being in the wind arranges described tuyere with lower air chamber 3 along drying tunnel direction interval.Make thus drying course hot blast blow to foil 50 more even, ensure better drying effect.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
