Description

A kind of glass tempering furnace thermal cycle forced convection device

Technical field

This utility model relates to the heating furnace of the Low emissivity LOW-E glass tempering of glass processing, especially a kind of fiberglass Change stove thermal cycle forced convection device.

Background technology

At present, the production heating technique of Low emissivity LOW-E glass tempering, mainly glass surface spraying one layer to three layers are prevented Heat radiation film layer, when heating, this film layer heat absorption rate is less than non-coat side, and due to the difference of being heated in two faces of glass, thermal expansion rate is not Synchronize, thus cause glass to be upturned when heating, when swinging in heating furnace, produce scratch on the bottom surface, affect glass surface Quality.

Blower fan forced convertion is to be positioned in high temperature furnace by 4-8 platform about 4KW blower fan, static the highest heat-resisting of heat resisting exhauster 200 ° of C degree of temperature, furnace temperature is about 700 ° of C degree, produces and needs 4-8 Fans to want continual operation, additional comprehensive energy consumption Higher, easily there are the phenomenons such as bearing locking in the high-temperature blower in stove, increases maintenance cost.

Another compressed air heat-exchange system, needs 22-37KW air compressor machine and 10M³The air accumulator of left and right, work Time, when compressed air is by heat exchanger, after compressed air is only preheating to about 400 ° of C, enter back in 700 ° of C stoves, increase energy Consumption；A part of heat further through a little blower fan from heat exchanger discharge, most furnace heat due to compressed-air actuated enter Entering and discharge body of heater from roller-way gap, causing the significant wastage of heat, this structure energy consumption high yield is low, and is only applicable to list The LOW-E glass of layer plated film；In view of above-mentioned many reasons, it is proposed that a kind of glass tempering furnace thermal cycle forced convection device.

Utility model content

The purpose of this utility model is to overcome China's current LOW-E glass production technology mainly to have blower fan forced convertion With compressed air heat-exchange system, blower fan forced convertion is to be positioned in high temperature furnace by 4-8 platform about 4KW blower fan, heat resisting exhauster 200 ° of C degree of static the upper limit temperature of heat tolerance, furnace temperature is about 700 ° of C degree, produce need 4-8 Fans want continual operation, Additional comprehensive energy consumption is higher, and the phenomenons such as bearing locking easily occurs in the high-temperature blower in stove, increases maintenance cost, by reasonably Design, it is provided that a kind of glass tempering furnace thermal cycle forced convection device, this utility model is to be forced heat by the blower fan being placed in outside stove The upper surface of glass is heated by air-flow, and balance glass upper and lower surface heat absorption, thermal expansion rate synchronizes, and then improves glass surface quality. This structure also can promote simple glass yield simultaneously, and the blower fan of forced convection device is placed in outside stove, can reduce blower fan long-time By heat ageing；Can open or close at any time according to job demand and close blower fan, compressed air heat-exchange system is compared, it is no longer necessary to pneumatics Machine and air accumulator, reduce energy consumption and reduce fault rate, reduce maintenance cost, reduce up-front investment, promote production capacity.

This utility model to achieve these goals, adopts the following technical scheme that, a kind of glass tempering furnace thermal cycle is forced Convection device, is by heating furnace, air collecting box, heat resisting exhauster, electric furnace heating wire, backflow exhaust duct, reflux heat wind pipeline, pottery conveying Roll, take out hot air duct, LOW-E glass composition；Heating furnace top arranges at least one heat resisting exhauster, below each heat resisting exhauster Furnace wall reserve two cross wall ways, in the middle part of the body of heater of heating furnace horizontally set one row's pottery conveying rolling, at least three potteries are defeated Sending rolling to arrange uniform arrangement, pottery conveying rolling row is arranged above with LOW-E glass；The pottery conveying portion of rolling in heating furnace is arranged Upper furnace, the pottery conveying portion of rolling down arrange lower hearth, arrange air collecting box, set in the lower hearth of heating furnace in the upper furnace of heating furnace Put electric furnace heating wire；

Air collecting box both sides arrange casing, arrange under hot blast serial pipe, air collecting box between two side box bodies on air collecting box top Arranging backflow exhaust duct between two side box bodies in portion, reflux at least three arrangements of the uniform setting of exhaust duct, below backflow exhaust duct The uniform steam vent that arranges, arranges electric furnace heating wire between two side box bodies in the middle part of air collecting box；

Between hot blast serial pipe and the heat resisting exhauster of air collecting box, reflux heat wind pipeline is set；Heat resisting exhauster and upper furnace it Between arrange take out hot air duct.

Provide the benefit that: this utility model is to be forced thermal current to heat the upper surface of glass by the blower fan being placed in outside stove, Balance glass upper and lower surface heat absorption, thermal expansion rate synchronizes, and then improves glass surface quality.This structure also can promote common glass simultaneously Glass yield, the blower fan of forced convection device is placed in outside stove, can reduce blower fan for a long time by heat ageing；According to job demand at any time Can open or close and close blower fan, compressed air heat-exchange system is compared, it is no longer necessary to air compressor machine and air accumulator, reduces energy consumption and reduces event Barrier rate, reduces maintenance cost, reduces up-front investment, promotes production capacity.
