Detailed description of the invention
The construction features of the 3mm glass tempering cooling air grid of compression air dielectric provided by the invention is described below in conjunction with accompanying drawing.
As shown in Figure 1, Figure 2, Figure 3 shows, described glass tempering cooling air grid has frame 1, frame 1 is provided with roller-way transporter 8 for transmitting high temp glass in the horizontal direction, air grid assembly 4 and lower air grid assembly 2 it is respectively disposed with in the upper and lower side of described roller-way transporter 8, described upper air grid assembly 4 is connected to lowering or hoisting gear 6 and lower lowering or hoisting gear 10 with lower air grid assembly 2, enables the vertical distance between air grid assembly 4 and lower air grid assembly 2 and described roller-way transporter 8 to regulate.
As shown in Figure 1A, it it is the gas circuit structure schematic diagram of the present invention, it is provided with air compressor 1, described air compressor 1 is connected with compensator 6 by moisture trap 4, described compensator 6 is connected with described upper air grid assembly 4 and lower air grid assembly 2 through a plurality of branch road 39 again, every branch road 39 is equipped with air relief valve 37 and Pressure gauge 38, thus the convenient air pressure regulated on each bar branch road 39.
Described lower air grid assembly 2, including the air grid unit 20 (spacing distance between air grid unit 20 is preferably equal with the roller-way spacing distance of roller-way transporter 8) that multiple rows of parallel interval is arranged, such as Fig. 4, Fig. 5, shown in Fig. 6, each described air grid unit 20 has the bellows 21 in flat, the bellows 21 of described flat are left, the right side is respectively arranged at two ends with left end support 22 and right-hand member support 23, the upper end face of the bellows 21 of described flat is arranged in the horizontal direction, and on described upper end face, offer spray-hole 24, the rear surface of the bellows 21 of described flat favours horizontal direction and arranges, the width making the bellows 21 of described flat linearly declines from left end toward right-hand member, it is provided with air intake joint 25 at described bellows 21 left end, described air intake joint 25 is connected with described compensator by described air relief valve, it is provided with cleaning door at described bellows 21 right-hand member, use plug screw 26 airtight under described cleaning door normality.
Owing to the width of bellows 21 linearly declines from left end toward right-hand member, when compression air enters in bellows 21 from described air intake joint 25, expulsion pressure away from the spray-hole 24 at air intake joint 25 place obtains corresponding compensation, the expulsion pressure difference that can make all spray-holes 24 reduces as far as possible, makes the cooling rate of each position of glass keep consistent.
The air pressure exported through air relief valve for the expulsion pressure and compensator that make air grid unit 20 adapts, the optional �� 1.1 of diameter or �� 1.3 (between �� 0.9-�� 1.5) of described spray-hole 24.
Further, in order to make whole glass surface up-draught pressure be more uniformly distributed, also can be set to larger diameter by described lower air grid assembly 2 goes out the spray-hole 24 on several air grid unit 20 of end corresponding to glass inlet side and glass, and the spray-hole 24 gone out on the several air grid unit 20 between end corresponding to glass inlet side and glass is set to small diameter.
