Plate glass melting furnace clarification portion stepped arch top

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.

Description

Technical field: [0001] The invention relates to a glass production equipment, in particular to a stepped roof of the clarification part of a flat glass melting furnace. Background technique: [0002] Flat glass melting furnace is the raw material melting equipment for flat glass production. It is functionally divided into melting part and clarifying part. Physically, melting part and clarifying part are one space. Logically, melting part and clarifying part are two functional areas. Melting part It is composed of hanging wall, crown, parapet, pool bottom, pool wall, etc. The clarification part is composed of parapet, parapet, gable, pool bottom, pool wall, etc., all of which are made of refractory bricks. Two independent structures, the connecting seam is horizontal, which can avoid thermal expansion interference. The raw materials are clarified in the clarification section after being melted in the melting section. The space of the clarification section is large, the heat ...

AI Technical Summary

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 of the arc of the crown of each clarification section, so that the corresponding vault heights are respectively reduced to form a stepped crown, and the space of the entire clarification section will also be reduced to reduce the heat dissipation area. For the purpose of reducing energy consumption, the crown and parapet are still connected horizontally, avoiding the thermal expansion interference between the crown and parapet
