Description

A kind of big arch brick of glass furnace for pure oxygen combustion

Technical field

The utility model relates to glassmaking art, the big arch brick of specially a kind of glass furnace for pure oxygen combustion.

Background technique

Glass furnace pure oxygen combustion technology imparts the flexile operation of glass furnace, glass furnace for pure oxygen combustion, Oxygen does not need to preheat, and eliminates regenerative chamber or heat exchanger, and kiln investment is greatly lowered, and the utilization rate of fuel improves, so that Glass melting quality is more stable, and melting rate significantly improves, but alkali steam and water vapor concentration largely increase in kiln, so that The corrosion at the positions such as kiln arch top also aggravates.How the service life and production performance more superior fire resisting of refractory material are extended Material becomes the hot issue of insider's concern.

Traditional kiln arch very useful arch brick surface be it is flat, in the glass metal volatile matter that arch top is formed, on arch top, liquefaction can not It disconnectedly trickles to both sides, has certain erosion to breast wall brick, and coking can be generated to the combustion rifle of breastwork, seriously affected combustion rifle Use.

Utility model content

(1) the technical issues of solving

In view of the deficiencies of the prior art, the utility model provides a kind of big arch brick of glass furnace for pure oxygen combustion, has Structure is simple, easy to use, can improve breast wall brick service life, will not influence combustion rifle use the advantages that, solve it is existing The glass metal volatile matter that kiln arch top is formed can constantly trickle to both sides in the liquefaction of arch top, and the erosion to breast wall brick influences to fire The problem of rifle uses.

(2) technical solution

In order to solve the above technical problems, the utility model provides the following technical solutions: a kind of glass furnace for pure oxygen combustion use Big arch brick, including big arch brick main body, it is characterised in that: the big trapezoidal body of arch brick main body, upper and lower ends are arc surface, two Side is plane, and the big arch brick lower body is additionally provided with a fin item, and the fin item is longitudinally arranged in big arch brick Lower body.

Preferably, the height of the fin item is 5cm, and shape is trapezoidal or semicircle.

Preferably, the length of the fin item is consistent with the longitudinal length of big arch brick main body, and with big arch brick main body at Integrated.

Preferably, the big arch brick main body and fin item are all made of alpha-beta aluminum oxide brick material.

(3) beneficial effect

Compared with prior art, the utility model provides a kind of big arch brick of glass furnace for pure oxygen combustion, has following The utility model has the advantages that

1, smooth mode is taken in traditional arch brick bottom, and the volatile matter of glass metal can be in arch in this way after assembling Push up to both sides trickle, to breast wall brick have it is certain wash away, while can to combustion rifle generate coking, seriously affect combustion rifle normal work Make, so optimization arch brick bottom structure, is changed to prevent volatile matter to two effluents in the mode of a flat raised fin item, reduce Erosion to breast wall brick will not influence combustion rifle and normally use.

2, the physical-chemical reaction that kiln front occurs is bigger, and temperature is high, and smoke components are also relatively more, washes away to arch Also more severe, so the refractory material of high temperature resistant, resistance to erosion must be selected, select alpha-beta refractory material, that is, alpha-beta oxidation Aluminium brick material, can very good solution high temperature resistant, it is corrosion-resistant the problems such as.

Detailed description of the invention

Fig. 2 is the left view of the utility model；

Fig. 3 is that the utility model forms arch roof construction schematic diagram.

In figure: 1, big arch brick main body；2, fin item；3, breast wall brick.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Please refer to Fig. 1-3, a kind of big arch brick of glass furnace for pure oxygen combustion, including big arch brick main body 1, it is characterised in that: The trapezoidal body of big arch brick main body 1, upper and lower ends are arc surface, and two sides are plane, and big 1 lower end of arch brick main body is also Equipped with a fin item 2, the fin item 2 is longitudinally arranged in big 1 lower end of arch brick main body.

Specifically, the height of the fin item 2 is 5cm, shape is trapezoidal or semicircle.

Specifically, the length of the fin item 2 is consistent with the longitudinal length of big arch brick main body 1, and with big arch brick main body 1 Integral shape.

Specifically, the big arch brick main body 1 and fin item 2 are all made of alpha-beta aluminum oxide brick material.

When in use, below big arch brick main body 1 be arranged a longitudinal direction fin item 2, by multiple big arch brick main bodys 1 according to Original groove splices arch roof construction in the arc-shaped above, and arc-shaped arch roof construction both ends are built upon on breast wall brick 3, breast wall brick 3 are equipped with combustion rifle, when alkali steam in the kiln of high temperature and water vapor concentration largely increase, so that portion gas liquefies to big arch On 1 rear surface of brick main body, when collected liquid is excessive, it can trickle to both sides, it is liquefied that the fin item 2 being at this moment arranged assembles collection Liquid, when weight reaches it is a certain amount of when, can automatically fall off, will not trickle onto breast wall brick, can not only reduce the erosion of breast wall brick, but also Do not influence the normal use of combustion rifle.

It should be noted that, in this document, its any other variant such as term " includes " is intended to nonexcludability Include so that include a series of elements process, method, article or equipment not only include those elements, but also Including other elements that are not explicitly listed, or further include for this process, method, article or equipment intrinsic want Element.In the absence of more restrictions, the element limited by sentence "including a ...", it is not excluded that including described want There is also other identical elements in the process, method, article or equipment of element.
