Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of large energy consumption caused by the large space of the clarification part and the large heat dissipation area. The top of the clarification part is divided into multiple sections, and the initial position of the top of each clarification part remains unchanged. The breast wall is still a horizontal connection joint, gradually reducing the central angle ...

Abstract

The invention relates to a plate glass melting furnace clarification portion stepped arch top which comprises breast walls (1) on the two sides of a melting furnace clarification portion, steel columns (3) on the outer sides of the breast walls, arch top supports (2) and arch top pulling rods (4). The arch top supports (2) and the arch top pulling rods (4) are arranged on the steel columns. The plate glass melting furnace clarification portion stepped arch top is characterized in that a circular-arc-shaped arch top body (5) with the gradually-reduced central angle is arranged between the breast walls on the two sides, the arch height of the arch top body is sequentially reduced to be in a step shape, and the two ends of the arch top body are connected with the breast walls through the arc top supports. Due to the adoption of the technical scheme, the whole clarification portion space is reduced, the aim of reducing energy consumption is achieved, horizontal connecting seams still exist between the arch top body and the breast walls, and thermal expansion interference between the arch top body and the breast walls is avoided.

Example Embodiment

[0012] like figure 1 , figure 2 As shown, a stepped roof of the clarification part of a flat glass melting furnace, which includes: parapets 1 on both sides of the clarification part of the melting furnace, steel columns 3 on the outside of the parapet, roof supports 2 and roof tie rods 4 set on the steel columns , which is characterized by a set of arc-shaped arches 5 with successively decreasing central angles along the parapets on both sides, so that the vault height h of the arches decreases successively in a stepped shape, and the two ends of the arches are connected to the parapets through the arches .

[0013] The described central angle is the angle of the apex on the center of the circle, and the two sides of the angle are two radii of the same garden, such as image 3 As shown, when the chord length of the arc is constant, the chord height h of the arc is proportional to the change of the central angle R, and the stepped crown of the present invention, the width of the crown (equal to the chord length of the arc) Similarly, the height of the arc-shaped crown (equivalent to the chord height of the arc) decreases with the decrease of the central angle of the segment crown, and the step-shaped crown changes from high to low, and its arc-shaped crown corresponds to The central angle changes from 62° to 50°.

[0014] The steel column and the crown tie rods are also adjusted accordingly with the corresponding crown height.

[0015] Due to the adoption of the above-mentioned technical solution, the space of the entire clarification part is reduced, achieving the purpose of reducing the heat dissipation area and reducing energy consumption. The crest and parapet are still horizontal joints, which avoids the interference of thermal expansion between the crest and parapet.
