Description

A flat glass furnace wall structure

technical field

The utility model relates to a wall structure of a plate glass melting furnace, which belongs to the technical field of plate glass production equipment.

Background technique

Flat glass melting furnace is the key equipment for flat glass production, which is composed of melting part, cooling part, neck, regenerator and others. The melting part is composed of pool wall, breast wall, pool bottom, roof and so on. The pool wall is made of refractory bricks. The pool wall brick is 250mm thick, 400-450mm wide, and ≥1250mm high. The top of the pool wall brick is 30-50mm higher than the glass liquid level, and does not bear the weight of the kiln body; The joint bricks are placed, which can be removed for hot repair of the furnace, and expansion joints are left; above the expansion joints are hook bricks and breast wall bricks.

During the use of the melting furnace, the molten glass will erode the pool wall of the melting part, and the erosion is most serious at the contact point between the liquid glass surface and the pool wall, which is the easily eroded part of the melting furnace pool wall. In order to slow down the erosion, a cooling air duct is installed on the corresponding outside of this part, which is specially used for air cooling. When working, in the flat glass melting furnace, the flame burns horizontally and horizontally, relying on radiation to heat the glass raw materials, the flame will directly radiate to the erodible parts, resulting in high working temperature, lower hardness and lower impact resistance of the erodible parts, resulting in The service life of the furnace is reduced. In a kiln life cycle (7-12 years), although the air-cooled pool wall can slow down the erosion speed, the erodible parts will still be almost completely eroded, so that the method of pasting refractory bricks must be used to maintain the kiln in the later period of the kiln life. It not only increases the maintenance cost, but also limits the service life of the furnace.

If the thickness of the easily eroded part of the flat glass melting furnace is increased, the outside air cooling will have little effect on the inner wall, and the erosion speed will be faster. Therefore, increasing the thickness of the eroded part has little effect on increasing the life of the eroded part.

Contents of the invention

The purpose of the utility model is to solve the problems existing in the current technology, and provide a flat glass melting kiln wall structure, which can effectively guarantee the kiln life cycle and increase the service life.

In order to achieve the above purpose, the technical means adopted by the utility model is: a flat glass furnace wall structure, including joint bricks, pool wall bricks, cooling air ducts, joint bricks are installed on the upper part of the pool wall bricks, cooling air The air outlet of the pipe is facing the outer wall of the pool wall brick, and the feature is that: the joint between the pool wall brick and the seam brick is provided with a flame-blocking block, and the bottom surface of the flame-blocking block is located above the glass liquid surface. the

Further, one side of the flame-blocking block is integrated with the pool wall brick, and the top surface of the flame-blocking block is located below the corresponding surface connecting the joint brick and the pool wall brick.

The beneficial effect of the utility model is that: the structure effectively ensures the normal use of the plate glass melting kiln pool within the kiln life cycle, reduces maintenance costs, and increases its service life.

Fig. 2 is the structural representation of the utility model.

In the figure: 1. Joint brick, 2. Pool wall brick, 3. Cooling duct, 4. Flame block.

Detailed ways

As shown in FIG. 1 , the wall structure of a flat glass melting furnace and its erosion process in the prior art.

A flat glass furnace wall structure as shown in Figure 2, including seam brick 1, pool wall brick 2, cooling air pipe 3, seam brick 1 is installed on the upper part of pool wall brick 2, and cooling air pipe 3 is air outlet The outer wall of the pool wall brick 2 is characterized in that: the joint between the pool wall brick 2 and the seam brick 1 is provided with a flame-blocking block 4, and the bottom surface of the flame-blocking block 4 is located above the liquid surface of the glass. the

One side of the flame-blocking block 4 is integrated with the pool wall brick 2, and the top surface of the flame-blocking block 4 is located below the corresponding surface of the connecting surface of the seam block 1 and the pool wall brick 2.

In order to increase the service life of the flat glass melting furnace, a flame block is attached to the top of the pool wall bricks to block the direct radiation of the flame to the eroded parts, in order to reduce the working temperature of the eroded parts and improve the anti-scouring ability of the eroded parts of the pool wall. This structure effectively ensures the normal use of the flat glass melting furnace pool within the kiln life cycle, reduces maintenance costs, and increases its service life.

The embodiments of the present application are only used to illustrate the technical features disclosed in the present application, and changes made by those skilled in the art through simple replacements still fall within the protection scope of the present application.
