Abstract

The utility model relates to a kind of Flat Glass Furnace fining end staged arch top, it comprises: the support of arch topmast (2) and the arch top pull bar (4) that on the steel column (3) in the breastwork (1) of melting furnaces fining end both sides, breastwork outside, steel column, arrange, it is characterized in that the arc arch top, garden (5) of reducing successively along being provided with one group of central angle between the breastwork of both sides, the sagitta that arch is pushed up reduces stepped successively, and the two ends on arch top are connected with breastwork by the support of arch topmast.Owing to having adopted technique scheme, whole fining end space reduces, and has reached the object that lowers energy consumption, and arch top is still level connection joint seam with breastwork, has avoided arch top and the thermal expansion of breastwork to disturb.

Description

A kind of Flat Glass Furnace fining end staged arch top

Technical field:

The utility model relates to a kind of glass manufacturing apparatus, particularly a kind of Flat Glass Furnace fining end staged arch top.

Background technology:

Flat Glass Furnace is the raw material melting equipment that sheet glass is produced, in function, be divided into melting end and fining end, physically melting end and fining end are a space, melting end and fining end are two functional zone in logic, melting end is by hanging screen, arch top, breastwork, at the bottom of pond, the compositions such as pool wall, fining end is pushed up by arch, breastwork, gable, at the bottom of pond, the compositions such as pool wall, by refractory materials brick masonry, form, arch top is two absolute construction with breastwork, connecting sewing is level, can avoid thermal expansion to disturb, raw material is clarified at fining end after melting end fusing, fining end space is large, area of dissipation is just large, power consumption is also just large.How to reduce fining end space, reduce area of dissipation and become energy-saving and cost-reducing key.For this problem, in China's utility model patent " a kind of Horizontal flame melting furnace " (patent No.: 201010559766.5), propose a kind of method that reduces fining end space, fining end arch top is longitudinally divided into 3～4 joints, then integral body has reduced every joint arch top zero position 100～200mm step by step.Although the method has reduced fining end space, reduced area of dissipation, but caused breastwork to be stairstepping, arch top has become ladder connecting sewing with breastwork by being originally that level connection joint stitches, in melting furnaces thermal expansion process, will make arch top and breastwork cause mutual extruding to disturb, so that squeeze crack fire proof material brick sustains damage breastwork.

Utility model content:

The purpose of this utility model is exactly large in order to solve fining end space, area of dissipation causes greatly the problem that power consumption is large, take fining end arch top to be divided into more piece, every joint fining end arch top zero position remains unchanged, arch top is still level connection joint seam with breastwork, gradually reduce the central angle of every joint fining end arch tip circle arc, corresponding arch crown height is reduced respectively and be staged arch top, whole fining end space also will reduce, reaching area of dissipation reduces and the object of attenuating energy consumption, arch top is still level connection joint seam with breastwork, avoided arch top and the thermal expansion of breastwork to disturb.

To achieve these goals, the utility model has adopted following technical scheme:

A kind of Flat Glass Furnace fining end staged arch top, it comprises: the support of arch topmast and the arch top pull bar that on the steel column in the breastwork of melting furnaces fining end both sides, breastwork outside, steel column, arrange, it is characterized in that the arc arch top, garden of reducing successively along being provided with one group of central angle between the breastwork of both sides, the sagitta that arch is pushed up reduces stepped successively, and the two ends on arch top are connected with breastwork by the support of arch topmast.

The arc arch top, garden that one group of described central angle reduces successively, its angle changes by 62 °～50 °.

Owing to having adopted technique scheme, whole fining end space reduces, and reaches area of dissipation and reduces and the object of attenuating energy consumption, and arch top is still level connection joint seam with breastwork, has avoided the thermal expansion of arch top and breastwork to disturb.

For more detailed explanation the utility model, following accompanying drawing provides a most preferred embodiment.

Accompanying drawing explanation:

Fig. 1 is schematic diagram of the present utility model;

Fig. 2 is the A-A view of Fig. 1;

Fig. 3 is the schematic diagram of central angle relation.

Embodiment:

As shown in Figure 1 and Figure 2, a kind of Flat Glass Furnace fining end staged arch top, it comprises: the support 2 of arch topmast and the arch top pull bar 4 that on the steel column 3 in the breastwork 1 of melting furnaces fining end both sides, breastwork outside, steel column, arrange, it is characterized in that the arc arch top, garden 5 of reducing successively along being provided with one group of central angle between the breastwork of both sides, the sagitta h that arch is pushed up reduces stepped successively, and the two ends on arch top are connected with breastwork by the support of arch topmast.

Described central angle is the angle of summit on the center of circle, two radiuses in the two Tiao Bianweitong gardens at angle, as shown in Figure 3, chord length one timing when circular arc, the action h of circular arc and central angle R are varied to direct ratio, staged arch described in the utility model top, the width (chord length that is equal to circular arc) on arch top is identical, garden arc spring of arch (action that is equal to circular arc) is along with the central angle on this section of arch top reduces and reduces, the change from high to low of staged arch top, its circular arc arch pushes up corresponding central angle angle to be changed by 62 °～50 °.

Described steel column and arch top pull bar are also along with corresponding spring of arch is done corresponding adjustment.

Claims

1. a Flat Glass Furnace fining end staged arch pushes up, it comprises: the support of arch topmast (2) and the arch top pull bar (4) that on the steel column (3) in the breastwork (1) of melting furnaces fining end both sides, breastwork outside, steel column, arrange, it is characterized in that the arc arch top, garden (5) of reducing successively along being provided with one group of central angle between the breastwork of both sides, the sagitta that arch is pushed up reduces stepped successively, and the two ends on arch top are connected with breastwork by the support of arch topmast.

2. a kind of Flat Glass Furnace fining end staged arch according to claim 1 top, is characterized in that: the arc arch top, garden (5) that one group of described central angle reduces successively, its angle changes by 62 °～50 °.
