Abstract
The utility model relates to a flat air grid structure for glass tempering. A plurality of air outlets are formed in the flat air grid structure, and used for wafting cooling air to the glass surface, wherein the air outlets are all towards the same direction and are used for wafting cooling air to the glass surface at the same angle of inclination to enable the flowing direction of the cooling air on the glass surface exhausted from any air outlet to be paralleled with the moving direction of the glass. As the flat air grid structure for glass tempering enables the flowing direction of cooling air to be in accordance with or be contrary to the glass moving direction, so that the flowing direction of the cooling air on the glass surface in the flat air grid structure is effectively controlled, the cooling air flows in the direction paralleled to the glass moving direction to the maximum extent, the order of the flowing of the cooling air is assured, the defect of warping of the glass, particularly the thin glass in the process of tempering and cooling, led by the uneven cooling of the surface of the whole glass plate brought by the conventional air grid structure, is overcome, and the processing quality of the glass is improved.
Description
Technical field
The utility model relates to the tempering field of glass, specifically the flat air grid structure in the cooling unit of glass tempering furnace.
Background technology
In glass fibre reinforced plastic equipment, flat air grid structure generally all adopts following several modes at present: one, in air grid, all wind hole air-out direction is vertical with glass surface.Two, same vent air-out direction vertical with glass travel direction in air grid equates with the angle of glass surface, but the air-out direction of different vents and glass surface angle are not etc., in these wind holes, some wind hole air-out direction is vertical with glass surface, the direction that some wind hole air-out direction moves with glass in the projection of glass surface is consistent, be that the direction that moves with glass of air-out direction is consistent, the opposite direction that some wind hole air-out direction moves at projection and the glass of glass surface, it is the opposite direction that air-out direction and glass move, the air-out direction in final all wind hole and the angle of glass travel direction have two to three kinds and the well-regulated arrangement in wind hole, this blowing mode can guarantee that the each point that each wind hole blows to glass surface is evenly distributed to greatest extent.Three, wind hole changes air nozzle structure into, and the air-out direction of tuyere is identical with first two mode.The flat air grid of said structure is in glass tempering process, owing to cannot effectively controlling in air grid cooling air in the flow direction of glass surface, make in the process of cooling of glass in flat air grid, always inhomogeneous cooling, cause glass especially the glass below 3mm in tempering process of cooling, produce warping phenomenon, finally cannot make the toughened glass of high-quality.
Utility model content
The warping phenomenon that causes glass to produce in tempering process of cooling for solving the flow direction of the uncontrollable cooling air of flat air grid of existing glass tempering in cooling, the utility model provides flat air grid structure for a kind of glass tempering.
The utility model is that the technical scheme that solves the problems of the technologies described above employing is: flat air grid structure for a kind of glass tempering, on flat air grid, be distributed with some air outlet openings, for blowing cooling air to glass surface, described air outlet opening towards all consistent, and all blow cooling air with identical angle of inclination to glass surface, so that the cooling air that any one air outlet opening is discharged is parallel at the flow direction of glass surface and the travel direction of glass.
The angle of inclination of described air outlet opening refers to the air-out direction of air outlet opening and the angle of glass vertical direction.
The angle of inclination of described air outlet opening is greater than 0 degree and is less than 90 degree.
The angle of inclination of described air outlet opening is preferably more than 0 degree and is less than 40 degree.
The angle of inclination of described air outlet opening is more preferably greater than 0 degree and is less than 15 degree.
Described flat air grid comprises several bellows, and the outlet air surface of each bellows is the scarp that obliquity is consistent, and air outlet opening is vertically set on scarp.
The angle of inclination on described scarp has guaranteed that roller inclination that the cooling air of the air outlet opening discharge being located thereon is avoided between adjacent bellows blow to glass surface.
Beneficial effect: the utility model makes the flow direction of cooling air consistent with glass travel direction or contrary, effectively control the flow direction of the interior cooling air of air grid at glass surface, cooling air is flowed along being parallel to the direction that glass moves to greatest extent, guarantee the order that cooling air is mobile, overcome the defect of the especially thin glass of glass warpage in tempering process of cooling that whole glass pane surface inhomogeneous cooling that existing flat air grid structure brings causes, improved the processing quality of glass.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Reference numeral: 1, flat air grid, 2, bellows, 3, air outlet opening, 4, roller, 5, glass.
Embodiment
As shown in the figure, a kind of flat air grid structure for glass tempering, on flat air grid 1, be distributed with some air outlet openings 3, for blowing cooling air to glass 5 surfaces, described air outlet opening 3 towards all consistent, and all blow cooling air with identical angle of inclination to glass 5 surfaces, so that the cooling air that any one air outlet opening 3 is discharged is parallel at the flow direction of glass surface and the travel direction of glass.
The angle of inclination of described air outlet 3 is greater than 0 degree and is less than 90 degree, is preferably more than 0 degree and is less than 40 degree, is more preferably greater than 0 degree and is less than 15 degree.
Described flat air grid 1 comprises several bellows 2, air outlet opening 3 is arranged on the outlet air surface of bellows 2, the outlet air surface of each bellows 2 that can described flat air grid 1 is set to the scarp that obliquity is consistent (vergence direction and angle of inclination are identical), air outlet opening 3 is vertically set on scarp, the wind direction of the cooling air that the each air outlet opening 3 of assurance is discharged is like this all consistent, and tilt to be blown into glass surface, thereby all parallel with the direction of motion of glass (all identical or all contrary) of cooling air that all air outlet openings 3 are discharged.
The cooling air that the air outlet opening 3 that the angle of inclination on above-mentioned scarp has guaranteed to be located thereon is discharged is avoided the roller 4 between adjacent bellows 2 and is tilted to blow to glass surface, to prevent that stopping of roller 4 from causing the change of cooling air wind direction.
This flat air grid structure applications, in annealing furnace unit, has guaranteed to be blown into the flow direction of lower surface cooling draught on glass identical with the travel direction of glass or contrary.
