Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a brick holder for a glass melting kiln, and more particularly to a brick holder for receiving a triangular prism-shaped hollow brick for a glass melting kiln.

[Prior Art and Problems] As is well known, exhaust gas discharged from the outlet of a glass melting furnace is led to a heat storage chamber and heats heat storage bricks. Additionally, the newly introduced air is heated by the preheated heat storage bricks. In either case, the transfer of heat between the bricks and the exhaust gas or air depends primarily on heat transfer. Therefore, it is desirable that the bricks have a large surface area and that the air flow is also turbulent.

By the way, conventionally, the above-mentioned glass melting kiln bricks have been used by being placed directly on the glass melting kiln.

However, in such cases, the glass melting kiln bricks are placed directly on the melting kiln, so there is a risk that the glass melting kiln bricks may be damaged by the melting kiln, and the heat storage effect of the glass melting kiln bricks is not sufficient. There was a problem.

The present invention has been made in view of the above circumstances, and provides a brick holder for a glass melting kiln that can avoid the bricks for a glass melting kiln from being damaged by the melting kiln and can improve the heat storage effect of the bricks for the glass melting kiln. The purpose is to

[Means for Solving the Problems] The present invention provides a brick holder for a glass melting kiln that is used by partially fitting into a groove of a rider section of a glass melting kiln.
This brick receiver for a glass melting furnace is characterized in that it has a channel having a substantially triangular cross-sectional shape in the vertical direction, and has a protrusion on the lower surface that fits into the groove of the rider section.

In the brick receiver according to the present invention, the cross-sectional shape of the channel of the brick receiver main body is approximately triangular. Specifically, the shape of the three inner corners of the brick receiver main body is, for example, rounded (see FIGS. 1 to 4). In addition, the shape of the three outer corners of the brick receiver body is also rounded (see Figure 2), or each has an angle of 60 degrees or more, preferably 120 degrees (Figures 1, 3, and 3). (See Figure 4).

These shapes should be determined in consideration of moldability, thermal stress during use, etc.

Examples of the material of the brick support for the glass melting furnace according to the present invention include magnesia, maguro, chromamag, high alumina, and chamotte.

[Function] According to the present invention, the brick for glass melting kiln is constructed by having a flow path having a substantially triangular cross-sectional shape in the vertical direction and having a protrusion on the lower surface that fits into the groove of the rider section. can be prevented from being damaged by the melting kiln, and the heat storage effect of the bricks for the glass melting kiln can be improved.

Examples of the present invention will be described below.

Furthermore, the height H1 of the brick receiver main body 1 is 100 cm, and a first protrusion 2 is provided on the upper surface of the brick receiver main body 1 to prevent displacement of, for example, 6 ms (H2). For example, a second protrusion 3 with a depth of 50a+i (D) for preventing displacement is provided. Here, the second protrusion 3 is fitted into a groove in a rider section of a glass melting furnace, and the length of its long side is, for example, 164.3a+a+(L12). Note that the second
