Description

Technical Field

[0001] The utility model relates to the technical field of glass manufacturing, in particular to a pool wall brick for a glass melting furnace, a glass melting furnace pool wall structure and a glass melting furnace. Technical Background

[0002] During the glass production process, the operational status of the glass melting furnace is crucial to the safety and efficiency of the entire production line. As a key component of the glass melting furnace, the tank wall tiles are subjected to extreme heat, chemical attack, and physical erosion. These factors combine to gradually thin the tank wall tiles. In severe cases, certain areas may leak or lose glass liquid, leading to serious safety accidents.

[0003] When the glass melting furnace reaches the middle and late stages of operation, the company usually takes external reinforcement measures for the pool wall bricks, such as sticking iron grates, tying bricks to the pool wall, etc. However, these practices not only consume a lot of manpower and material resources, but also, if the thickness of the pool wall bricks cannot be accurately grasped in time, huge economic losses may be caused due to failure to maintain or replace them in time. Summary of the Invention

[0004] In view of the defects of the prior art, the purpose of the present invention is to provide a pool wall brick for a glass melting furnace, a glass melting furnace pool wall structure and a glass melting furnace.

[0005] The technical solution of the utility model is:

[0006] The first aspect of the present invention provides a pool wall brick for a glass melting furnace, comprising a pool wall brick body, wherein a blind hole matching a brick thickness measuring rod is provided on the side wall of the pool wall brick body; the blind hole is arranged obliquely relative to the side wall of the pool wall brick body; the blind hole comprises an open end and a bottom end opposite to the open end; in the vertical direction, the position of the open end is higher than the position of the bottom end.

[0007] Preferably, the depth of the blind hole is greater than the inner diameter of the blind hole.

[0008] Preferably, a sealing member is detachably filled in the blind hole.

[0009] Preferably, the sealing element is sealing cotton.

[0010] Preferably, the sealing cotton is high temperature resistant polycrystalline fiber cotton

[0011] Preferably, the brick thickness measuring rod is a high temperature resistant metal rod.

[0012] A second aspect of the present invention provides a glass melting furnace pool wall structure, comprising a plurality of pool wall bricks, wherein the pool wall bricks are any of the pool wall bricks described above.

[0013] A third aspect of the present invention provides a glass melting furnace, comprising the glass melting furnace pool wall structure described above.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The pool wall bricks provided by the present invention can conveniently measure the pool wall thickness through the blind holes opened on the side walls of the pool wall bricks; specifically, users can monitor the residual thickness of the pool wall bricks after erosion at any time according to their needs, thereby accurately predicting the time when the glass melting furnace pool wall needs to be reinforced and tied with bricks, ensuring the timely procurement and preparation of relevant materials, or taking other appropriate measures to ensure the continuous and stable operation of the glass melting furnace.

[0016] 2. The pool wall tiles provided by this utility model cleverly utilize non-penetrating blind holes in the side walls. This design does not damage the overall structure of the tiles, ensuring the integrity and density of the contact surface between the pool wall tiles and the molten glass. This effectively prevents the risk of molten glass leakage during the initial stages of glass melting furnace operation. Furthermore, the use of blind holes for inspection is simple and easy, significantly reducing labor and material resources, and has a positive impact on improving production safety and efficiency.

[0022] The present invention will be described in detail below with reference to specific embodiments.

[0023] The following examples will help those skilled in the art further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that those skilled in the art may make several changes and improvements without departing from the scope of the present invention, and these changes and improvements are all within the scope of protection of the present invention.

[0024] Example 1

[0025] This embodiment provides a tank wall tile for a glass melting furnace, comprising a tank wall tile body 3. A blind hole 4 is provided on the sidewall of the tank wall tile body 3, adapted to accommodate a thickness measuring rod. The blind hole 4 is inclined relative to the sidewall of the tank wall tile body 3. The blind hole 4 includes an open end and a bottom end opposite the open end. Vertically, the open end is positioned higher than the bottom end. If the tank wall tile body 3 is corroded by molten glass, causing the blind hole 4 to penetrate, the inclined blind hole 4 prevents the molten glass from flowing out of the furnace, effectively preventing major safety accidents.

[0026] In this embodiment, when it is necessary to measure the remaining thickness of the eroded portion of the pool wall brick, the brick thickness measuring rod is inserted into the pool wall brick body 3 along the trajectory of the blind hole 4 to perform the measurement operation.

[0027] In one embodiment, the depth of the blind hole 4 is greater than the inner diameter of the blind hole.

[0028] In one embodiment, the blind hole 4 is detachably filled with a sealing member.

[0029] Furthermore, in this embodiment, the sealing member is sealing cotton.

[0030] Furthermore, in this embodiment, the sealing cotton is high-temperature resistant polycrystalline fiber cotton.

[0031] In one embodiment, the brick thickness measuring rod is a high temperature resistant metal rod.

[0032] If the remaining thickness of the pool wall tile body 3 is not required, the blind hole 4 can be sealed with high-temperature resistant polycrystalline fiber cotton. This effectively prevents heat from dissipating through the blind hole and blocks cooling air from the pool wall from entering the kiln through the blind hole 4, ensuring a stable kiln environment. To measure the remaining thickness of the pool wall tile body 3, simply remove the high-temperature resistant polycrystalline fiber cotton and insert a high-temperature resistant metal rod into the pool wall tile body 3 along the path of the blind hole 4 to perform the measurement.

[0033] Example 2

[0034] This embodiment provides a glass melting furnace pool wall structure, which is built by multiple pool wall bricks. The pool wall bricks used in this embodiment are the pool wall bricks described in Example 1.

[0035] Example 3

[0036] This embodiment provides a glass melting furnace, comprising breast wall bricks 2, hook bricks 1, and the glass melting furnace pool wall structure described in Example 2. The hook bricks 1 are located above the glass melting furnace pool wall structure, and the breast wall bricks 2 are located above the hook bricks 1, with the hook bricks 1 and breast wall bricks 2 tightly fitted together.

[0037] The following takes a tank wall brick with a thickness of 250 mm as an example to illustrate the implementation effect of the tank wall brick for a glass melting furnace, the tank wall structure of a glass melting furnace and the glass melting furnace provided by the above-mentioned embodiment.

[0038] A blind hole 4 with a depth of 70 mm and a diameter of 25 mm is opened on the side wall of the pool wall brick body 3. The blind hole 4 is set at an angle, and the position of the open end of the blind hole 4 is higher than the position of the bottom end, and the bottom end is flush with the glass liquid level 5. The pool wall brick body 3 is equipped with a high-temperature resistant metal rod for measuring the thickness of the brick body.

[0039] When using this pool wall brick to build the pool wall structure of the glass melting furnace, it is stacked in the melting zone where the erosion of the glass melting furnace is most serious. The hook brick 1 is located above the pool wall structure of the glass melting furnace, and the breast wall brick 2 is located above the hook brick 1. The breast wall brick 2 fits tightly with the hook brick 1 and is used together to maintain the stability of the glass melting furnace and resist damage to the pool wall bricks caused by chemical erosion and high temperature radiation.

[0040] During the operation of the melting furnace, the inner side of the pool wall brick is slowly eroded by the molten glass, so the thickness of the pool wall brick will gradually become thinner. When the erosion reaches the bottom end of the blind hole 4 opened on the side wall of the pool wall brick body 3, the blind hole 4 of the pool wall brick body 3 will become a through hole that passes through the inside and outside. A high-temperature resistant metal rod is inserted from the open end of the blind hole 4. When the high-temperature resistant metal rod can contact the molten glass, it means that the remaining thickness of the pool wall brick is ≤70mm.

[0041] During the operation of the melting furnace, the remaining thickness of the pool wall bricks is regularly measured using the above method through the blind holes 4 opened in the side walls of the pool wall brick body 3 to determine when the pool wall bricks in the melting zone need to be tied to ensure the safe use of the pool wall bricks and the melting furnace.

[0042] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the specific embodiments described above, and those skilled in the art may make various changes or modifications within the scope of the claims, which do not affect the essence of the present invention. In the absence of conflict, the embodiments of the present application and the features in the embodiments may be combined with each other in any manner.
