Description
Affiliated technical field
The utility model belongs to the float glass technology, mainly proposes the mechanism that cools in a kind of float glass lehr hot air convection district.
Background technology
Float glass need experience that " carrying out high temperature melting in the raw material cooperation-melting furnaces becomes to draw in the typing-annealing furnace in glass metal-float glass process moulding molten tin bath and anneal-processes such as cold junction cutting, packing, warehouse-in.Wherein, acting as of float glass lehr: about 600 ℃ glass ribbon of tin groove forming is progressively reduced to 60 ℃ (or room temperatures) by a series of rational temperature controls, come the size and the distribution of stress in the feed glass by the temperature-fall period rational temperature, and then reach the purpose that prevention glass burst and optimized glass cutting.By the requirement of annealing process stress control, annealing furnace is divided into holding-zone, closed section, open section.As shown in Figure 2, (glass ribbon top) is provided with radiation cooled tube 10 in annealing furnace holding-zone 1, the blast inlet of radiation cooled tube 10 is positioned at the outside of annealing furnace, the other end of radiation cooled tube 10 is provided with induced draft fan 7, in the freezing air suction radiation cooled tube with the annealing furnace outside, make cooling air countercurrent flow in radiator tube (reverse), the glass ribbon in the kiln is carried out the radiation cooling with the glass ribbon traffic direction, air in the radiator tube is heated simultaneously, expels from kiln through induced draft fan 7.In the hot air convection district of annealing furnace closed section is that Ret district 2 is provided with hot blast cooling tube 15, one end of hot blast cooling tube 15 is positioned at stove, the other end is positioned at stove equally and tuyere 12 is set in the termination, make tuyere be positioned at glass ribbon above and below and corresponding with glass ribbon, hot blast cooling tube 15 is provided with induced draft fan, to be induced draft fan with the warm air in the stove extract out to enter to chew from wind in the hot blast cooling tube again blows to the purpose that the glass ribbon surface reaches cooling, simultaneously, the hot blast cooling tube be provided with make that cool exterior air enters import 14 and the butterfly valve 6 of control air output, hot blast in the hot blast cooling tube 15 and the cold wind that enters from the outside enter induced draft fan simultaneously and mix hot blast into about 120 ℃, then via the air-out pipeline of induced draft fan, tuyere 12 blows to glass surface in the kiln.Because Ret district cooling hot blast derives from and extracts the kiln space hot blast, can cause the local space of this district and adjacent sections to form negative pressure, because the spindle nose of this district and adjacent sections glass live roll 4 can not be accomplished to seal fully; Therefore can cause cool exterior air to be inhaled into by live roll spindle nose slit, thereby cause the pernicious interference of cool exterior air to annealing situation in the kiln, cause in the kiln vertically lower the temperature gradient and transverse temperature difference of glass ribbon bigger, and then cause the serious skewness of temporary stress of glass ribbon and burst with variation of ambient temperature.
Summary of the invention
The purpose of this utility model is the mechanism that cools that proposes a kind of float glass lehr hot air convection district, the above-mentioned defective that makes it can avoid existing cooling cooling body to deposit.
The technical scheme that the utility model is finished its invention task proposition is: in the hot air convection district of annealing furnace is that the Ret district is provided with the hot blast cooling tube, the one end is positioned at annealing furnace, the other end enters in the annealing furnace and in the termination after by induced draft fan tuyere is set, tuyere is positioned at the above and below of glass ribbon and corresponding with glass ribbon, and the hot blast cooling tube is provided with the cold wind import and is provided with the air output control valve; It improves structure: the hot blast cooling tube is communicated with the radiation cooled tube of holding-zone by pipe connecting, and inlet one end that is about to hot blast cooling tube induced draft fan is communicated with air outlet one end of radiation cooled tube induced draft fan by pipe connecting.Thus, the hot blast that the radiation cooled tube of annealing furnace holding-zone is discharged directly enters in the hot blast cooling tube in annealing furnace Ret district, chews ejection to the glass ribbon cooling of lowering the temperature from wind.During work, annealing furnace hot air convection district is that the Ret district can utilize hot blast that the holding-zone radiation cooled tube discharges to the glass ribbon cooling of lowering the temperature, and the original structure in this district can still keep, but only does standby.
The annealing furnace hot air convection district that the utility model proposes mechanism that cools can make full use of the original mechanism that cools in this district, and its improvement part is simple in structure, and easy handling has overcome the existing defective of original structure effectively.
