Abstract

The utility model discloses a water-cooling combination device which can replace the tank wall of a glass melting furnace, so as to prolong the service life of the glass melting furnace. The device is used for comprehensively wrapping and sealing secondary tiles on the wall of an eroded pool in the later stage of operation of the glass melting furnace so as to replace the eroded tiles. The device can directly block the leakage of high-temperature molten glass. The utility model discloses among the technical scheme, including metal box water chiller one, metal box water chiller two and advance the return water and insert partial subassembly between them. The utility model is a water-cooling combination device with less investment, quick effect and easy operation, which is suitable for the maintenance and remedy of the eroded tank wall in the later stage of the operation of the glass melting furnace.

Description

Water-cooling combined device for replacing wall of glass melting furnace

Technical Field

The utility model discloses water-cooling composite set is formed by two combination of two kinds of specification and dimension's box water coolers of metal one and box water cooler of metal, is applied to the maintenance of equipment technical field that glass melting furnace has been corroded the pool wall, specifically is one kind and can replace glass melting furnace to be corroded position pool wall, ensures the sustainable steady operation's in melting furnace later stage a hot maintenance mode.

Background

In the prior art, the refractory material of the wall of the glass melting furnace tank is directly washed and burnt by molten glass, batch and flame under the high-temperature condition for a long time, so that the wall of the upper tank of the melting furnace contacting with the molten glass becomes a key part which is seriously damaged. In order to slow down the erosion of the refractory material of the tank wall, the cold surface of the tank wall is locally cooled by air at the initial operation stage of the melting furnace so as to slow down the erosion speed of the tank wall through temperature reduction. However, in one kiln operation cycle (8-10 years), the refractory material at the upper layer part of the wall of the kiln is gradually eroded away due to the scouring under the high-temperature condition. Therefore, whether the pool wall bricks can normally run is the key for influencing the service life of the kiln, and has great significance for influencing the production quality of glass.

At present, in domestic methods for maintaining the wall of a melting furnace tank, besides local air cooling, local tiling is also adopted, namely, a cold surface of the upper layer part of the tank wall is attached with zirconia-corundum bricks (75-100mm in thickness) made of the same material to replace the corroded tank wall. However, the tiling can be performed only twice at most, and when the second tiling is eroded, the third tiling cannot be performed due to the limitation of the thickness of the pool wall tiling and the operation space of the melting furnace, and further, the molten glass liquid leakage accident can occur, which finally leads to the shutdown of the melting furnace.

Disclosure of Invention

The utility model solves the problem that the corroded secondary tiling on the tank wall can not block the glass liquid in the melting furnace. Adopt novel water-cooling composite set, including metal box water chiller one and metal box water chiller two, wrap up sealed mode to two cold faces in the bottom and the outside of pool wall secondary tiling all-roundly, replace by erosion position pool wall refractory material, prevent that the glass liquid from leaking the occurence of failure, ensure that the melting furnace lasts steady operation.

The invention relates to a water-cooling combined device which has less investment, quick effect and easy operation and can replace the eroded tank wall of a glass melting furnace, comprising a metal box type water cooler I and a metal box type water cooler II.

The present invention will be further explained with reference to the following embodiments.

Description of the drawings: fig. 1 is a schematic diagram of the application principle of the present invention.

In the figure, 1, a first metal box type water cooler, 2, a second metal box type water cooler, 3, secondary tiling, 4, primary tiling, 5, hook tiling, 6, molten glass, 7, pool wall and 8, I-shaped steel upright post

Detailed Description

As shown in figure 1, the utility model discloses water-cooling composite set, including metal box water chiller 1 and metal box water chiller two 2, to the bottom of pool wall secondary tiling 3 and two all-round parcel sealing methods that carry out in the outside two cold faces, replace the position pool wall refractory material that erodees. After the wall of the glass furnace tank is put into use for about 4 years, the upper tank wall near the surface line of the molten glass in the melting furnace is seriously eroded, and at the moment, a first-time tile 4 is required to be additionally arranged on the cold surface outside the tank wall corresponding to the seriously eroded part so as to prevent the leakage of the molten glass. After the tiled wall of the melting furnace runs for about 2 years again, the primary tiles 4 are gradually eroded, the secondary tiles 3 are added on the outer cold surface of the furnace, and after the furnace runs for about 2 years again, the secondary tiles 3 are eroded again, but at the moment, because the thickness of the tiles on the wall of the furnace and the operation space between the wall of the furnace and the I-shaped steel upright post 8 are limited, the tiles cannot be tiled for the third time on the part. If the red penetration phenomenon is found at the part of the secondary tile 3 which is eroded and eroded on the outer side of the tank wall 7 during the operation of the melting furnace, the secondary tile 3 is eroded and thinned and has the hidden danger of leaking glass liquid. At this time, the second metal box type water cooler 2 which is designed and manufactured in advance is filled with circulating cooling water and is arranged at the bottom of the secondary tile 3 to replace the previous bearing steel beam. And secondly, mounting the designed and manufactured metal box type water cooler I1 which is filled with water on the part, extending out of the tile, of the top surface of the metal box type water cooler II 2, so that the metal box type water cooler I1 is tightly attached to the outer surface of the secondary tile 3. And thirdly, tightly supporting and fixing the outer surface of the metal box type water cooler I1 by using jackscrews arranged on I-steel upright posts 8 on two sides of the melting furnace, and finally completely wrapping and sealing the bottom end and two cold surfaces on the outer side of the secondary tile 3 on the tank wall.
