Description

A kind of insulation setting device of rolled glass melting furnaces overflow port edge

Technical field

The utility model relates to the insulation setting device of float glass production unit, particularly a kind of insulation setting device of rolled glass melting furnaces overflow port edge.

Technical background

In current existing rolled glass production line, the high temp glass liquid of melting flows out from overflow port, and the glass channel through an open type flow to calendering mouth place, crosses rolling press calendering formation.Wherein glass channel is made up of the rib brick on both sides, because temperature is relatively low, the temperature of fusion of edge glass metal declines, viscosity is large, poor fluidity, prolonged stay very easily forms crystallization material, and process can damage stack not in time, and directly affect effective glass band width, thus reduce glass finished-product rate.In order to overcome the above problems, the Heat preservation method generally adopted at present burns limit fire, by directly blowing the mode of burning edge glass metal, improves temperature of glass liquid, to reduce the transverse temperature difference of glass metal in whole glass channel.

And the following problem of burning limit fire device ubiquity of rolled glass production line use at present: 1. flame is uneven, and the flame intensity of middle part is large, blows burning area little, easily causes glass metal local superheating; 2. according to the difference of glass ware forming thickness, take normal adjusting edge firelock flame intensity and particular location, and traditional burning limit fire device is substantially all mix handmade steel pipe by limit firelock to form, its direction, angle not easily adjust; 3. burning limit nozzles burn for a long time and easily produce lime-ash or close-burning thing, and drop after stain glass metal, and have the risk of damage stack; 4. burn limit fire for a long time and consume more Sweet natural gas, add production cost.

Utility model content

The utility model object is the problem in order to solve melting furnaces overflow port temperature inequality, and provides a kind of insulation setting device of rolled glass melting furnaces overflow port edge.

To achieve these goals, the utility model have employed following technical scheme:

A kind of insulation setting device of rolled glass melting furnaces overflow port edge, comprise melting furnaces, melting furnaces are provided with overflow port, the both sides of described melting furnaces are provided with rib brick, brick top, every side block limit is equipped with one flame-baffling wall, at described melting furnaces arranged outside bracing frame, it is characterized in that: connect a track girder in the upside of support frame as described above, the downside of track girder is slidably connected a trave lling girder, trave lling girder hangs connection supporting beam, the both sides of supporting beam all hang one group of insulating brick, and two groups of insulating brick corresponding matching are in the both sides of described overflow port.

On the basis of technique scheme, following further technical scheme can also be had:

Two rollers are fixedly connected with in the upside of described trave lling girder, two rollers all roll and are engaged on described track girder, two pulleys are fixedly connected with in the downside of described trave lling girder, described trave lling girder also connects an electric hoist, each described pulley all rolls the rope that is connected, one end of every root rope is all connected with described electric hoist, and the other end of every root rope hangs the respective end being connected to described supporting beam respectively.

The both sides of described supporting beam are equipped with one group of suspension rod, and every root suspension rod is corresponding hanging one block of insulating brick all.

Be provided with a deck in one end of described trave lling girder, one end of described track girder is provided with a buckle, buckle snap-fit engagement corresponding to the through hole of described trave lling girder.

Often organize described brick to fit mutually placement, and often organize insulating brick and all have part to stretch out described overflow port.

The requirement of overflow oral area to refractory materials of rolled glass production line is higher.Compared with common refractory materials, coefficient of linear expansion and the high temperature creep of fused quartz ceramic are less, and in temperature lower than within the scope of 1200 DEG C, thermal conductivity, along with the rising of temperature, increases slowly.The thermostability excellent just because of fused quartz ceramic and ageing-resistant performance, can ensure prolonged application under the overflow port temperature environment of about 1100 DEG C.

The present invention utilizes suspension rod by fire resistant heat preserving cover block hanging side by side bonded to each other for several piece above overflow port edge glass metal, forms the thermal environment of a relative closure with overflow port limit brick.When high temp glass liquid flows through edge region, the cover block of partial radiation heat through top is reflected back glass metal surface, thus reduces heat loss, plays certain insulation effect to edge glass metal.Insulation cover block adopts the mode of polylith laminating, is heated each other relatively uniform, prevents bulk cover block centralized head load from easily causing fracture.Further, the present invention utilizes pulley and roller set as transmission mechanism, electric hoist is as control device, achieve the free adjustment in the horizontal and vertical directions of insulation cover block, compare traditional burning limit fire device, under the prerequisite ensureing good heat insulation effect, simple economy more, also laborsaving more flexibly when regulating or change.

Advantage of the present utility model: this device achieves the free adjustment of temperature on melting furnaces overflow port level and vertical direction, compare traditional burning limit fire device, under the prerequisite ensureing good heat insulation effect, simple economy more, also laborsaving more flexibly when regulating or change.
