Glass kiln furnace feeding opening pool wall brick protection structure

Abstract

The invention discloses a glass kiln furnace feeding opening pool wall brick protection structure, which comprises a pool wall body positioned around a glass kiln furnace feeding opening, wherein a protection brick layer is arranged under the inner side of the pool wall body; the thickness of the protection brick layer is more than 1 / 2 of the thickness of the pool wall body; the height is more than 1 / 3 of the height of the pool wall body. Further, the protection brick layer is built by bricks made of the same materials as the pool wall body or bricks made of fireproof materials with better performance. Further, a steel structure protector is arranged at the outer side of the pool wall body; a water cooling pipeline is arranged in the steel structure protector. The top of the steel structure protector is fixedly connected with the outer side of the pool wall body through an anchor rod. The design in each position is matched; the safety of the kiln furnace can be enhanced; the service life of the kiln furnace is prolonged; the product quality and the economic benefits are improved.

Description

technical field [0001] The invention belongs to the field of glass preparation equipment, in particular to a wall brick protection structure of a glass kiln feeding port, which is used to prolong the service life of the pool wall. Background technique [0002] For the construction of a conventional float glass furnace, the tank wall of the feeding port is made of several AZS pool wall bricks whose main component is zirconia. , because the part of the pool wall that is severely eroded by the glass solution is at the middle and lower part of the pool wall at 300-1200 mm, especially in the field of electronic glass containing electric boosting, the melting amount is too small, and the feeding pool is too wide. The material layer is too thin, the melting speed is too fast, and the material pile is too short (basically no obvious material pile), resulting in the temperature of the molten glass in the feeding pool being 200-400°C higher than that of ordinary float glass melting fu...

[0002] For the construction of a conventional float glass furnace, the tank wall of the feeding port is made of several AZS pool wall bricks whose main component is zirconia. , because the part of the pool wall that is severely eroded by the glass solution is at the middle and lower part of the pool wall at 300-1200 mm, especially in the field of electronic glass containing electric boosting, the melting amount is too small, and the feeding pool is too wide. The material layer is too thin, the melting speed is too fast, and the material pile is too short (basically no obvious material pile), resulting in the temperature of the molten glass in the feeding pool being 200-400°C higher than that of ordinary float glass melting furnaces. The decomposition reaction of carbonate and sulfate is also limited to the vicinity of the end wall of the feeding tank, unlike ordinary float glass melting furnaces where the reaction occurs far away from the feeding tank, so over time, the tank wall The erosion of the pool will inevitably increase gradually, and the middle and lower parts of the pool wall will be damaged and thinned, which will affect the service life of the pool wall of the entire feeding port.
