Description

Technical Field

[0001] The utility model relates to the field of flat glass production, in particular to a novel glass melting furnace pool wall iron grate device. Background Art

[0002] The melting furnace is the heart of the flat glass production line. The service life of the melting furnace mainly depends on the erosion and burning degree of the melting furnace pool wall, large crown, heat storage chamber, etc., and the erosion and damage degree of the pool wall is the most critical part affecting the life of the melting furnace. In the middle and late stages of the operation of the melting furnace pool wall, the pool wall thickness is relatively thin, and a larger cooling air is required to cool the outside of the pool wall. This can slow down the erosion rate of the pool wall bricks and extend the life of the pool wall. However, excessive pool wall cooling air will increase the temperature difference between the inside and outside of the pool wall, which may cause risks such as cracking of the pool wall bricks and leakage of glass liquid.

[0003] Although the iron grates of the melting furnace pool wall in the prior art can reinforce the pool wall bricks and maintain the original structural stability of the pool wall bricks, the main problem with the iron grates of this structure is that they hinder the cooling effect of the pool wall cooling air on the pool wall bricks. The wind direction of the pool wall cooling air is about 20° away from the pool wall bricks, and blows from bottom to top toward the pool wall bricks. The iron grates of the prior art cut off the direct contact between the cooling air and the pool wall bricks, hinder the flow of the cooling air on the outside of the pool wall bricks, reduce the air volume of the cooling air acting on the outside of the pool wall bricks, and reduce the cooling effect of the cooling air on the pool wall bricks, thereby failing to better achieve the purpose of reducing the temperature of the outside of the pool wall bricks by the cooling air, and thus failing to better slow down the erosion rate of the pool wall bricks, seriously affecting the life of the melting furnace pool wall.

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] Although the iron grate 3 of the melting furnace pool wall in the prior art can reinforce the pool wall bricks 2 and maintain the original structural stability of the pool wall bricks 2, the main problem with the iron grate 3 of this structure is that it hinders the cooling effect of the cooling air 6 on the pool wall bricks 2. The direction of the cooling air 6 is at an angle of about 20° with the pool wall bricks 2, and blows from bottom to top toward the pool wall bricks 2. The iron grate 3 of the prior art cuts off the direct contact between the cooling air 6 and the pool wall bricks 2, hinders the flow of the cooling air 6 on the outside of the pool wall bricks 2, reduces the air volume of the cooling air 6 acting on the outside of the pool wall bricks 2, and reduces the cooling effect of the cooling air 6 on the pool wall bricks 2, thereby failing to better achieve the purpose of reducing the temperature of the outside of the pool wall bricks by the cooling air 6, and thus failing to better slow down the erosion rate of the pool wall bricks 2, seriously affecting the life of the melting furnace pool wall.

[0020] The utility model provides Figures 1 to 3 A technical solution shown: a new type of iron grate device for the pool wall of a glass melting furnace, including pool wall bricks 2 and cooling air ducts 4. An iron grate 3 is arranged on the outer side of the pool wall bricks 2. The iron grate 3 is formed by crossing a horizontal beam flat iron 7 and a longitudinal beam flat iron 8 to form a plurality of rectangular holes 10. Both the horizontal beam flat iron 7 and the longitudinal beam flat iron 8 are provided with holes.

[0021] The longitudinal flat iron 8 is kept vertically to the pool wall brick 2, and at the same time, the longitudinal flat iron 8 is crossed with the crossbeam flat iron 7 to form an effective constraint reinforcement structure to ensure the stability and safety of the pool wall brick 2. By adjusting the size and number of holes on the crossbeam flat iron 7 and the longitudinal flat iron 8 of the iron grate 3, the flow rate of the cooling air 6 can be flexibly controlled so that the cooling air 6 can pass smoothly, which solves the problem of the pool wall iron grate 3 in the prior art hindering the direct contact between the pool wall cooling air 6 and the pool wall brick 2, increases the flow rate of the cooling air 6, and realizes comprehensive and efficient cooling of the outside of the pool wall brick 2.

[0022] In this embodiment, the hole is a U-shaped air door hole 9, and each side of the rectangular hole 10 corresponds to a U-shaped air door hole 9. The opening directions of the U-shaped air door holes 9 set on the horizontal beam flat iron 7 and the longitudinal beam flat iron 8 are consistent, and the U-shaped air door holes 9 are set on the contact side of the pool wall brick 2.

[0023] The U-shaped air gate hole 9 ensures the smooth passage of the cooling air 6. The reasonably arranged U-shaped air gate hole 9 ensures the uniform distribution of the air volume and minimizes the wind resistance, thereby achieving efficient circulation of the cooling air 6 and solving the problems of accumulation and eddy current of the cooling air 6 in the prior art, making the cooling effect more significant.

[0024] In this embodiment, the angle between the pool wall brick 2 and the iron grate crossbeam flat iron 7 is A, and the angle A is 0° to 90°. The pool wall brick 2 is provided with an insulation brick 5, and the insulation brick 5 is located on the lower side of the iron grate 3. The insulation brick 5 is used to reduce the heat loss inside the glass melting furnace. Cooling air 6 flows inside the cooling air duct 4, and the cooling air 6 completely passes through the iron grate 3 to cool the pool wall brick 2.

[0025] The wind direction of the cooling air 6 is at an angle of 20° to the pool wall brick 2, and it blows toward the pool wall brick 2 from bottom to top. The cooling air 6 enters the iron grate 3 along the rectangular hole 10 of the iron grate 3. Under the action of the inclined angle of the crossbeam flat iron 7, the cooling air 6 is smoothly guided to the outside of the pool wall brick 2, and can fully contact the outside of the pool wall brick 2. At the same time, the problem of the iron grate 3 in the prior art that hinders the cooling air 6 from directly dissipating heat and cooling the pool wall brick 2 is solved, and the cooling effect of the cooling air 6 on the pool wall brick 2 is greatly improved.

[0026] The contents involved in the above embodiment are described below in conjunction with a preferred embodiment.

[0027] The iron grate 3 described in the utility model is formed by the intersection of a horizontal beam flat iron 7 and a longitudinal beam flat iron 8, and is formed by welding or casting; the longitudinal beam flat iron 8 of the iron grate 3 is perpendicular to the pool wall brick 2, and the angle between the horizontal beam flat iron 7 and the pool wall brick 2 is A, and A is adjustable from 0° to 90°. This angle A is equal to the wind direction of the cooling wind 6 and the angle between the pool wall brick 2. During processing and manufacturing, different angles A are adjusted according to the different wind directions of the cooling wind 6 of different production lines. By controlling the angle A between the horizontal beam flat iron 7 and the pool wall brick 2, the wind directions of the horizontal beam flat iron 7 and the cooling wind 6 are made parallel and consistent.

[0028] The iron grate 3 of the utility model is welded and installed on the outer upper part of the pool wall brick 2 (at the glass liquid surface line) through the melting furnace pool wall angle steel. The high-temperature glass liquid 1 (1580°C) is inside the pool wall brick 2. As the high-temperature glass liquid 1 flows, the high-temperature glass liquid 1 flushes the pool wall brick 2, causing the pool wall brick 2 to be thinned. When the furnace pool wall is running to the middle and late stages and the pool wall bricks 2 are slightly thinner, it is necessary to add iron grates 3 at the liquid level line where the pool wall bricks 2 are most severely eroded, to restrain and reinforce the pool wall bricks 2, and to keep the original pool wall brick 2 structure stable when the pool wall bricks 2 burst, to prevent the risk of leakage of high-temperature glass liquid 1. As the high-temperature glass liquid 1 flushes the pool wall bricks 2, the pool wall bricks 2 will become thinner and thinner, and the cooling air 6 will be opened wider and wider. The function of the cooling air 6 is to cool the outer side of the pool wall and reduce the temperature of the outer side of the pool wall, so as to slow down the erosion rate of the pool wall bricks 2 and extend the life of the pool wall. By controlling the angle A between the crossbeam flat iron 7 and the pool wall bricks 2, the angle A is 20°, so that the wind direction of the crossbeam flat iron 7 and the cooling air 6 are parallel and consistent.

[0029] The cooling wind 6 is blown out from obliquely below, first passes through the iron grate 3 of the pool wall, and then acts on the pool wall bricks 2. When the cooling wind 6 enters the iron grate 3 along the rectangular hole 10 of the iron grate 3, U-shaped air gate holes 9 are opened on the contact sides of the horizontal beam flat iron 7 and the longitudinal beam flat iron 8 of the iron grate 3 with the pool wall bricks 2. The U-shaped air gate hole 9 can guide and drain the cooling wind 6. When the cooling wind 6 passes through the cooling air duct 4 and enters the iron grate 3, the cooling wind 6 can achieve large-area cooling and cooling of the pool wall bricks 2 under the guiding effect of the U-shaped air gate hole 9, and this U-shaped air gate hole 9 does not hinder the cooling wind 6, so that the cooling wind 6 can cool the pool wall bricks 2 to a greater extent.

[0030] Under the guidance of the U-shaped air door hole 9, the cooling air 6 can fully contact the outer side of the pool wall brick 2. When the pool wall of the melting furnace is running to the later stage, the pool wall is very thin. At this time, the cooling air 6 has a large air volume, which will cause a large temperature difference between the inside and outside of the pool wall brick 2, and it is very easy to cause the pool wall brick 2 to crack and other phenomena. Therefore, at this time, it is necessary to add an iron grate 3 at the liquid level line of the pool wall that is prone to cracking, so as to maintain the original structure of the pool wall brick 2 stable. In this way, even if the pool wall brick 2 cracks, there will be no accident of leakage of high-temperature glass liquid 1, and it can also give the technical personnel enough time for maintenance and processing.

[0031] The iron grate 3 described in the utility model not only has the function of reinforcing and restraining the pool wall bricks 2 in the prior art, but also solves the problem that the iron grate 3 in the prior art blocks the cooling air 6 from cooling the pool wall bricks 2. The iron grate 3 described in the utility model can maximize the cooling air 6 to cool the pool wall bricks 2 over a large area and with high efficiency, thereby slowing down the erosion rate of the pool wall and extending the life of the pool wall bricks 2. In addition to the above advantages, the U-shaped air door hole 9 design of the iron grate 3 also has certain energy-saving and environmental protection characteristics. By optimizing the air volume and flow direction, unnecessary energy loss and waste can be reduced, thereby reducing production costs.
