Abstract

The utility model relates to a pressing machine by a flowing out method for slag nucleated glass, and is composed of a flowing-out chamber, a flowing-out groove, an upper and a lower calendering rolls, a hot fire adding nozzle in the flowing-out chamber, a support for the flowing-out groove, a supporting roll, a glass liquid down-pouring opening, etc. The glass liquid vertically flows on the lower calendering roll which rotates by the tail part of the flowing-out groove, and the upper calendering roll and the lower calendering roll rotate correspondingly to calender the glass liquid into a glass plate with a definite thickness and a definite width not to result in the blockage of devitrification.

Description

Cinder microcrystalline glass hydrostomia method calendering formation machine

The utility model is a kind of cinder microcrystalline glass hydrostomia method calendering formation equipment that is used for, and is a kind of glass manufacturing machine.

Devitrified glass forming method in the past has pouring, press great waves and calendering, rolling process can continuously shaped certain thickness and the sheet material of width, technical difficulty is big, domesticly built up three continuous calendering production lines once, all because of not failing by continuous operation, the kiln feed mode of this rolling press is imitated common figured glass, being that kiln tail glass metal is parallel overflows to two Ping Yanfa between the pressure roller, because of cinder microcrystalline glass than limit for height on the simple glass crystallization, material property is short, calendering continues for some time roller front glass liquid and contact with the water-cooled stack and form crystallization, and the mobile glass metal is blocked, the production interruption.Surplus this device fabrication time length maximum 30 hour, the shortest have only 4-6 hour, its device structure synoptic diagram such as Fig. 2.

Task of the present utility model is the weak point at above-mentioned parallel overflow rolling process, in conjunction with limit for height on the devitrified glass recrystallization temperature and the short characteristics of material property, design hydrostomia method calendering formation machine, overflow devitrified glass liquid is kept in chute more than the brilliant upper limit of folding, can not separate out brilliant next, afterbody to chute promptly vertically pours down to the bottom calender roll that rotates, and upper and lower in relative rotation stack calendering formation is a sheet glass.. can not stop up by crystallization, but the long-time continuous running.

Structure of the present utility model as shown in Figure 1, by hydrostomia chamber 1, hydrostomia groove 3, last stack 6, bottom calender roll 7, hydrostomia chamber heating chews 8, hydrostomia groove supporting 9, carrying roller 10, geat 11 constitutes under the glass metal; Have geat 11 under the glass metal below the hydrostomia chamber 1, be positioned at hydrostomia chamber central authorities the hydrostomia groove 3 of support in hydrostomia groove supporting 9 is installed, be equipped with under the hydrostomia groove 3 to add and showing tremendous enthusiasmly chew 8, face under the glass metal and be equipped with, go up stack 6,7 and carrying roller 10 below the geat 11.Hydrostomia chamber 1 left end connects melting furnaces, flow through the glass metal 4 that comes has bead by both sides hydrostomia groove 3 from melting furnaces, vertical streamer is to the lower compression roller 7 that is rotating, upper and lower pressure roller relatively rotates, glass metal is rolled into certain thickness sheet glass while cooling off, be transferred to the transition roller platform that the sealing heating is rotated through carrying roller, and deliver in the recrystallization annealing temperature roller kiln.

Embodiment of the present utility model, on, downward pressure roller adopts thermal conductivity big, the intensity height is difficult for the steel of oxidation and makes, on, the lower roll diameter proportion is 1: 3.5-4.5, and on the correlation technique, the bottom calender roll diameter is through being 1: 1, on, the bottom calender roll rotating speed is adjustable, linear velocity be generally 30-40 rice/minute, in the adjusting, lower roll thickness can be suppressed the sheet glass of different thickness, on, bottom calender roll is hollow, in water-cooling system is arranged, the may command roll surface temperature, the hydrostomia chamber adds and showing tremendous enthusiasmly chews 8 and can heat and keep glass metal more than recrystallization temperature, in order to avoid glass metal crystallization in hydrostomia groove 3 in the hydrostomia chamber 1.

The utility model has the advantages that the glass metal that flows down from salivation chamber 1 is immediately by upper and lower pressure Prolong and be rolled into glass plate, never can cause and analyse the brilliant breaks in production of stopping up, use this equipment, giving birth to Produce continuous operation 3 wheat harvesting periods on the line, produce thick 5-12m/m, wide 800mm slag Microcrystal glass plate, sheet material is smooth, dimensionally stable, performance is up to standard.
