Abstract
The invention relates to a compressed air quenching section special for an ultrathin tempered glass production line and a quenching method of the compressed air quenching section. The compressed air quenching section comprises a quenching air grid section, wherein a high-speed cooling air grid in a compressed air quenching device in the quenching section is divided into an upper air grid and a lower air grid; an upper air inlet and a lower air inlet in the upper and lower air grids are respectively communicated with a compressed air cooling medium system; and outlets of upper and lower radiating channels of the upper and lower air grids are respectively provided with an upper exhaust fan and a lower exhaust fan which are used for exhausting air for an active exhaust system on a high-pressure section. The compressed air quenching section has the advantages that 1, waste hot air can be rapidly exhausted when the hot air coated with glass rushes in the air grid, and the energy loss is greatly reduced; and 2, the cooling medium is compressed air, the flow velocity is high, and the pressure is high, so that the tempered glass has high cooling capacity and good tempering effect.
Description
Technical field
The present invention relates to a kind of by thickness at the continuous tempering of the ultra-thin glass of below 2.5mm and tempering standard can reach the ultra-thin toughened glass production line special pressurized air quenching section and quenching method that national building materials toughened glass requires, toughened glass production line can genus and manufacture field.
Background technology
Traditional continuous tempering furnace forms primarily of upper slice platform, preheating section, process furnace, high pressure section, braking section, cooling section and bottom sheet platform five major part; The off-set facility such as additional blowers, bellows and wind pipeline, electric control system and computer terminal.Former sheet glass enters stove, through preheating section from upper slice platform. arrive heating zone again. and be heated to the temperature of applicable tempering, then enter the even promptly quenching of strengthening segment, then enter bottom sheet platform, can from bottom sheet platform unloading piece.Whole process is all by microcomputer automatic control.Wherein During Quenching is the air adopting gas blower to export, and because its pressure is low, flow velocity is slow, and temperature is high, therefore causes again the quantitative increase of cooling blower, thus increases energy consumption, reduces tempering efficiency.Its weak point: one is because cooling power is not enough, cannot realize the tempering to ultra-thin glass; Two is that glass conveying mechanism transmission stability is poor, poor synchronization, and not easily shirks, not enough to emergency case processing power; Three is laterally enter stove due to glass and strike a beeline, and cause head of glass temperature drift, what the temperature in regulating stove do not affect to glass, causes by the Heating temperature of heating glass surface uneven, has the problem of front and rear side length variations; Four are roller conveying rollers in glass tempering furnace and are linear contact lay between glass, and the spacing of two rollers is comparatively large, cannot guarantee to be heated glass indeformable; Five is main outlet of still and quenching section air grid relative engagement of glass tempering furnace, comparatively wide arc gap is left in its combination section, the heat of the glass surface of walking is taken away by this gap, thus has to improve the temperature of glass in glass tempering furnace, causes energy consumption increase, glass surface Quality Down; Six is quenching section air grids is passivity heat radiation, and warm air squeezes away by the blast that relying on air grid completely provides, and cause the hot gas residence time long, heat build-up is at air grid itself, and air grid temperature is high; Seven is heat-eliminating mediums is air of the certain pressure provided by gas blower, and this medium temperature is high, pressure is low, flow velocity is slow, causes cooling power not enough.
Summary of the invention
Purpose of design: avoid the weak point in background technology, design a kind of can by thickness at the continuous tempering of the ultra-thin glass of below 2.5mm and tempering standard can reach the ultra-thin toughened glass production line special pressurized air quenching section and quenching method that national building materials toughened glass requires.
Design: in order to realize above-mentioned purpose of design.1, glass tempering outlet of still is convex mouth formula passage and the outlet of the convex mouth formula passage design relative with the socket joint import of quenching device, is one of technical characteristic of the present invention.The object done like this is: because the space of convex mouth formula passage is less than glass tempering furnace furnace chamber, jet pipe valve is opened, force high temperature gas flow to be formed at convex mouth formula passage and accelerate jet, the ultra-thin glass glass that this jet can be coated with all the time by heating pours quenching device together, so both avoid the loss of glass surface heat, ensure that the quality of toughened glass, and without the need to deliberately improving glass by Heating temperature, reduce energy consumption.2, the heat dissipation channel on the upper air grid of quenching device and lower air grid is interconnected and the design of exhaust fan and lower exhaust fan is equipped with in the outlet of heat dissipation channel respectively up and down, is technical characteristic two of the present invention.The object done like this is: be negative pressure ventilation due to what be positioned at that upper exhaust fan on upper air grid and lower air grid and lower exhaust fan formed air grid chamber, heat of high temperature in air grid chamber can not only be taken away by rapidly, and the residence time of hot gas at air grid can be shortened widely, avoid heat build-up at air grid.3, quenching media adopts the design of pressurized air quenching, is technical characteristic seven of the present invention.The object done like this is: adopt pressurized air as heat-eliminating medium, because pressurized air has the advantages that pressure is large, flow velocity is high, temperature is low, thus have stronger cooling power, meet needs and the tempering quality of ultra-thin glass tempering.
Technical scheme 1: a kind of ultra-thin toughened glass production line special pressurized air quenching section, comprise quenching air grid section, in described quenching section, the Fast Cooling type air grid of pressurized air quenching device divides air grid and lower air grid, and the blast inlet up and down in upper and lower air grid is communicated with pressure-air cooling medium system respectively.
Technical scheme 2: the quenching method of a kind of ultra-thin toughened glass production line special pressurized air quenching section, when by the ultra-thin glass that heats by glass tempering furnace out time, high temperature gas flow in glass tempering furnace gushes and is coated in high temperature gas flow by the ultra-thin glass after heating and pours quenching section quenching together outside glass tempering outlet of still, be arranged in the tuyere ejection compression cooling air at a high speed of the pressurized air quenching device of quenching section, under compressed-air actuated effect, flow velocity is higher, pressure is larger, temperature is lower, the cooling performance of cooled glass is the most obvious, energy consumption is minimum, temperature needed for glass tempering quality is best.
The present invention is compared with background technology, and one is achieve to allow warm air be wrapped in glass rush in wind Gate while, can be drained by discarded warm air rapidly, greatly reduce energy loss; Two is that heat-eliminating medium adopts pressurized air, and flow velocity is higher, and pressure is larger, and make by the cooling power of toughened glass stronger, tempering effect is best.
