Abstract
The utility model relates to an air injection cooling device comprising a spray pipe and a spray nozzle, wherein the spray pipe is provided with a groove; the spray nozzle is composed of two stainless steel plates; one ends of the two stainless steel plates are respectively and obliquely welded on two ends of the groove in the spray pipe, and a spray gap is formed by a gap existing between the other ends of the two stainless steel plates; an included angle formed by the ends, which are used for forming the spray gap, of the two stainless steel plates of the spray nozzle, ranges from 45 DEG to 70 DEG; two sides of the spray gap are provided with plugs; the gradually-reduced stable spray gap is formed by a trapezoidal structure welded between the two stainless steel plates according to a certain distance; and the plugs welded on two sides of the spray gap are used for avoiding lateral leakage of gas. The spray nozzle is welded on the spray pipe, so that the local resistance loss caused by sudden shrinkage of airflow is reduced, the efficiency of an air injection device is increased, the power consumption of a fan motor is reduced, and meanwhile, the airflow at the spray gap is uniform and stable to ensure that strip steel is uniformly cooled.
Description
Technical field
The utility model relates to a kind of refrigerating unit, relates in particular to a kind of air blown refrigerating unit.
Background technology
The technique of stainless steel plate annealing is stainless steel plate to be heated to jet by freezing air behind 1000 ℃ of left and right again be cooled fast to 200 ℃ of left and right.Prior art is by blower fan, air to be blown in circular pipe with the steel upper and lower surface, and of pipeline blocks and opens on the direction with steel at pipe surface a gap and forms the spray seam cooling zone steel of jetting.The shortcoming of this technology is that air is directly blown out through too small spray seam by large space in pipe arrangement, and shock resistance is large, and the efficient of blower fan is low; And for not affecting cooling homogeneity, the spray seam can not be fixed device, causes spraying seam because the thermal radiation of tape steel is out of shape, and affects the stability of air-out speed, is unfavorable for cold with steel.
The utility model content
Technical problem to be solved in the utility model is to provide that a kind of cooling efficiency is high, refrigerating unit is stablized on-deformable air blown refrigerating unit.
the technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of air blown refrigerating unit, comprise jet pipe, nozzle, described jet pipe is provided with groove, described nozzle is comprised of two stainless steel plates, one end of described two stainless steel plates tilts to be welded on respectively the both sides of jet pipe upper groove, space between the other end of described two stainless steel plates forms the spray seam, it is 45 °～70 ° that two stainless steel plates of described nozzle consist of the angle angular range that forms between that end of spray seam, the both sides of described spray seam are provided with plug, the ladder structure that is welded at regular intervals between two stainless steel plates forms the stable spray seam of convergent, the plug of spray seam both sides welding prevents the gas bleeder.
The beneficial effects of the utility model are: by welding tip on jet pipe, not only reduce the local resistance loss that air-flow causes because of sudden contraction, improve the air blown device efficient, reduce the consumed power of blower motor, simultaneously, the air-flow of spray seam is uniform and stable, and assurance is evenly cooling with steel.

Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example only is used for explaining the utility model, is not be used to limiting scope of the present utility model.
as shown in Figure 1, a kind of air blown refrigerating unit, comprise jet pipe 1, nozzle 4, described jet pipe 1 is provided with groove 2 towards the working face with steel 3, described nozzle 4 is comprised of two stainless steel plates, one end of described two stainless steel plates tilts to be welded on respectively the both sides of jet pipe 1 upper groove 2, space between the other end of described two stainless steel plates forms the spray seam, it is 45 °～70 ° that two stainless steel plates of described nozzle 4 consist of the angle angular range that forms between that end of spray seam, the both sides of described spray seam are provided with plug, the ladder structure that is welded at regular intervals between two stainless steel plates forms the stable spray seam of convergent, the plug of spray seam both sides welding prevents the gas bleeder.
In the welded-steel plate construction of a kind of air blown refrigerating unit of the utility model, evenly be provided with many group jet pipes 1 in needs cooling both sides with steel 3, and the jet pipe symmetric offset spread that needs cooling both sides up and down with steel 3, the entrance of jet pipe 1 is connected with the outlet of blower fan 5 by valve 6, valve 6 is controlled blower fan 5 and is entered the flow of jet pipe apoplexy, when unit starting, blower fan 5 starts, air is stitched ejection fast through pipeline and valve 6 from the spray of nozzle 4, form forced convection and come quick cooling zone steel 3, the air-flow of spray seam is uniform and stable, and assurance is evenly cooling with steel.
The above is only preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (3)
1. air blown refrigerating unit, it is characterized in that: comprise jet pipe, nozzle, described jet pipe is provided with groove, described nozzle is comprised of two stainless steel plates, one end of described two stainless steel plates tilts to be welded on respectively the both sides of jet pipe upper groove, and the space between the other end of described two stainless steel plates forms the spray seam.
