A rolling glass melting furnace and its strengthening method

Abstract

The invention discloses a rolling glass melting furnace and a strengthening method thereof. A transitional arch structure is arranged between the branch passage and the transverse passage, and the transition arch structure includes a section of transition interposed between the parapet of the transverse passage and the parapet of the branch passage. The parapet, the transition parapet and the parapet of the branch passage are integrally built, and the height is lower than that of the parapet of the branch passage, including the transition bridge across the transition parapet; the height of the entrance gate of the branch passage, the transition gate and the branch passage are increased in turn, forming a stepped Structural structure. In this way, the high-temperature gas emitted from the expansion straight joint can be avoided from ablation of the supporting steel member of the horizontal passage, and the expansion straight joint can also be sealed; and the outside of the lateral passage parapet on the side of the branch passage is exposed to the air, and the air can The parapet plays a cooling role.

Description

technical field [0001] The invention relates to the technical field of glass production, in particular to a rolling glass melting furnace and a method for strengthening the rolling glass melting furnace. Background technique [0002] Photovoltaic glass is a high transmittance glass material used in photovoltaic modules, which is produced by rolling process. Because the greater the melting capacity of the glass melting furnace, the lower its energy consumption, and the lower the production cost of the corresponding glass. Therefore, the melting furnace used for the production of photovoltaic glass is a furnace with multiple lines (multiple branch passages), that is, multiple branch passages are set on one side of a horizontal passage and perpendicular to the horizontal passage, and each branch passage is connected in parallel to the horizontal passage. superior. In normal production, glass raw materials are first melted into molten glass at high temperature in the melting p...

AI Technical Summary

Problems solved by technology

There is an expansion straight seam 14 at the contact point between the branch passage 7 and the cross passage breast wall 2, high-temperature gas will come out during the kiln and normal operation, and it cannot be sealed, and the high-temperature gas will burn the supporting steel of the cross passage 1 Component 13, causing safety problems in the horizontal passageway 1, which may lead to its collapse in severe cases

At the same time, during the baking kiln or normal production process, the cross passage parapet 2 with a length of 45 meters and a height of 1.8 meters has a relatively high center of gravity, and the inner and outer sides of the cross passage breast wall 2 on the side directly in contact with the branch passage 7 are in a high-temperature environment. Both sides are subjected to physical erosion and chemical erosion of high-temperature gas, which is easy to be burned and deformed, and cannot be repaired in a hot state, eventually leading to collapse

If one of the above two situations occurs, the production will be suspended, and the glass melting furnace needs to be released in advance to cold repair the glass melting furnace, resulting in a decrease in glass production efficiency and an increase in production costs.
