Description
Technical field
The utility model relates to the venturi air curtain used in a kind of drying chamber.
Background technology
In paint line, existing through type drying chamber body is generally drop on ground or a little more than ground, because workpiece continues through, thus workpiece is imported and exported is unlimited all the time, at the both ends (import and export) of through type room body, air curtain district is set, thus the hot-air closed in drying chamber body, prevent heat loss.Air curtain forming apparatus conventional in the body of through type room is air curtain airduct, namely the air curtain airduct be laterally oppositely arranged is housed in the end of room body, thus form the circulative convection of air, and need the equipment such as equipped air curtain EGR, the air curtain forming apparatus of this structure, its mounting structure is complicated, cost of manufacture is high, and there is the shortcoming that hot blast obturation effect is poor and thermal loss is large.
Utility model content
It is good and can the venturi air curtain of preheat fresh air that the technical problems to be solved in the utility model is to provide a kind of hot blast obturation effect.
For solving the problems of the technologies described above, the venturi air curtain provided comprises the ventilation duct being connected to drying chamber end of body, its design feature is: drying chamber body inner top is provided with dividing plate, form the new wind be communicated with ventilation bone between dividing plate and drying chamber body inwall and enter chamber, be provided with between the end of dividing plate and drying chamber body side wall inner surfaces for new wind pass through pass through mouth, dividing plate is connected with from end described in it to downward-extension and gradually to the deflector that drying chamber intracoelomic cavity is obliquely installed, the sidewall of drying chamber body is connected with the drainage plate be oppositely arranged with deflector, gap between deflector and drainage plate opposite face forms the tuyere gone out for new wind.
Deflector is connected with upper junction plate, and upper junction plate is provided with at least one elongated hole, and dividing plate is connected with fixed head, and upper junction plate is by being connected on dividing plate through the bolt of fixed head, dividing plate and described elongated hole.
Angle distraction plate is housed between deflector and upper junction plate.
The top of drainage plate is connected with sidewall connecting plate, bottom is connected with bottom support plate, and sidewall connecting plate is bolted on the sidewall of drying chamber body, the sidewall of drying chamber body is also equipped with the bracket of support bottom support plate.
Described deflector and drainage plate be arranged in parallel and are all 50 degree with horizontal angle.
After adopting said structure, the drying chamber venturi air curtain apparatus that the utility model provides no longer needs both sides in drying chamber body to arrange air curtain circulation airduct and circulation air supply device, thus enormously simplify the room body structure of drying chamber, and in drying chamber body, be blown into air by venturi tuyere, air blows to the workpiece of turnover drying chamber, make near ports air pressure above the lee face of workpiece relatively low, thus generation suction-operated causes the flowing of air, powerful eddy current can be formed, not only greatly strengthen hot blast obturation effect, and in closed drying chamber body, while hot-air, also serve the effect of preheat fresh air.
In sum, to have hot blast sealing effect good and can the advantage of preheat fresh air for the utility model.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is the structural representation of a kind of most preferred embodiment of the utility model;
Fig. 2 is the structural representation after Tu1Zhong A district amplifies.
Detailed description of the invention
Venturi air curtain as shown in Figure 1, the structure be arranged on for this venturi air curtain in drying chamber shown in Fig. 1, the end sections of drying chamber is only illustrated in Fig. 1, the concrete structure of drying chamber is prior art, be not described in detail at this, dotted arrow line shown in figure is the flowing signal of fresh air, solid arrow line shown in figure is the traffic direction of workpiece, this venturi air curtain comprises the ventilation duct 2 being connected to drying chamber body 1 end, drying chamber body 1 inner top is provided with dividing plate 3, form the new wind be communicated with ventilation bone 2 between dividing plate 3 and drying chamber body 1 inwall and enter chamber 4, be provided with between the end of dividing plate 3 and drying chamber body 1 side wall inner surfaces for new wind pass through by mouth 14, dividing plate 3 is connected with from end described in it to downward-extension and gradually to the deflector 5 that drying chamber body 1 inner chamber is obliquely installed, the sidewall of drying chamber body 1 is connected with the drainage plate 6 be oppositely arranged with deflector 5, gap between deflector 5 and drainage plate 6 opposite face forms the tuyere 7 gone out for new wind.
As depicted in figs. 1 and 2, deflector 5 is connected with upper junction plate 8, in the present embodiment deflector and upper junction plate one-body molded, upper junction plate 8 is provided with at least one elongated hole 15, dividing plate 3 is connected with fixed head 9, upper junction plate 8 passes through through fixed head 9, the bolt of dividing plate 3 and described elongated hole 15 is connected on dividing plate 3, the position of bolt in elongated hole can be adjusted thus the position of adjustment deflector 5, namely the gap between deflector 5 and drainage plate 6 is adjusted, the size of adjustment tuyere 7, deflector and drainage plate be arranged in parallel and are all 50 degree with horizontal angle, with 50 degree of angle blowing downs, define powerful eddy current, hot blast sealing effect is good, the bottom of deflector 5 is also provided with the diversion section 51 of one section of bending downwards, thus make distinguished and admirablely to blow to workpiece.Angle distraction plate 10 is housed between deflector 5 and upper junction plate 8, the angle of deflector can be ensured, the top of drainage plate 6 is connected with sidewall connecting plate 11 integrated with it, bottom is connected with bottom support plate 12, sidewall connecting plate 11 is bolted on the sidewall of drying chamber body 1, the bracket 13 of support bottom support plate 12 sidewall of drying chamber body 1 is also equipped with, said structure Absorbable organic halogens support drainage plate 6, thus ensure the shape of tuyere, ensure hot blast obturation effect.
The above is specific constructive form of the present utility model; the utility model is not restricted to the described embodiments; the art personnel, replace all in protection domain of the present utility model based on the equivalent variations of concrete structure on the utility model and parts.
