Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As depicted in figs. 1 and 2, a kind of glass line comprise subsequent annealing stove, many pump arm 1, and pump house steward 2, air draft chimney 3 and Forced draught blower 4.Subsequent annealing stove is provided with cooling annealing section, pumps arm 1 for many and distribute along its length to the exit of this cooling annealing section from the middle of cooling annealing section, pump the entrance of arm 1 towards crystallizing glass sheet material 8.Pump house steward 2 to be connected with many outlets of pumping arm 1, air draft chimney 3 with pump house steward 2 and be connected, the air suction inlet of Forced draught blower 4 with pump house steward 2 and be connected.The length of cooling annealing section is 2/5ths of subsequent annealing stove total length.This glass line, the second half section of its cooling at subsequent annealing stove annealing section is installed additional and pumps pipe (pump arm 1 and pump house steward 2), waste heat on crystallizing glass sheet material in stove 8 is taken away by pumping pipe by Forced draught blower 4, and discharged by air draft chimney 3, thus decrease the exhaust heat time of crystallizing glass sheet material 8, improve crystallization quality, also have compressed the length of cooling annealing section, make the length cooling annealing section be only subsequent annealing stove total length 2/5ths (length of subsequent annealing stove is 248m in the present embodiment, changing can increase 24.8m from now on and be used for crystallization), thus reduce cost and the production cost of glass line.
A kind of embodiment, as shown in Figure 1, pumps arm 1 and is uniformly distributed along its length to the exit of this cooling annealing section from the middle of cooling annealing section.So, crystallizing glass sheet material 8 Slow cooling can be made, the crystal effect needed for acquisition.
Another kind of embodiment, as shown in Figure 2, the arrangement density of pumping arm 1 near cooling annealing section middle is greater than the arrangement density of pumping arm 1 near cooling annealing section exit.Thus, first waste heat on crystallizing glass sheet material 8 can be extracted out rapidly in the middle of cooling annealing section, and then slowly extract out, thus obtain required crystal effect.
In order to control the amount of extracting waste heat out, to prevent air draft chimney 3 overheated, cause the shortening in work-ing life of this air draft chimney 3, so, preferably, every root is pumped on arm 1 and is provided with one first variable valve 5, further preferably, pumping on house steward 2 and be provided with the second variable valve 6, controlling pumpability by regulating the first variable valve 5 and/or the second variable valve 6.
