Abstract
Description
Technical Field
[0001] The present application relates to the technical field of high temperature equipment, and in particular to a passage space structure and a pool kiln. Background Art
[0002] The passage space structure in the fiberglass tank kiln refers to the refractory masonry structure containing a cavity above the wall bricks of the heating molten pool in the tank kiln. The common passage space structure is composed of masonry bricks on both side walls and cover bricks on the top, and forms a flame space, wherein burner bricks are provided on the side walls, and flames are provided by placing burners in the burner to heat the glass liquid in the flame space.
[0003] After the pool kiln is put into operation, the burner bricks are in a high temperature environment for a long time, which makes the burner bricks easy to burn out and become unusable. Therefore, the burned burner bricks need to be replaced in time. However, since the burner bricks are connected to other structures by wet masonry with fire mud, it is difficult to replace the burned burner bricks alone in a hot state; if the burner bricks are to be taken out and replaced, other structures around the burner bricks need to be removed in a hot state first, which will not only cause safety hazards to the operation of the passage, but also increase the cost of refractory materials and labor costs during the replacement process, which will have an adverse impact on production. Summary of the invention
[0004] In order to solve the above technical problems, the present application provides a passage space structure and a pool kiln, which can realize the individual replacement of burner bricks in a hot state, which can reduce safety hazards and reduce material costs and labor costs.
[0005] According to a first aspect of the present application, a passage space structure is provided, comprising:
[0006] a first support portion;
[0007] A burner brick portion, arranged on the first supporting portion, the burner brick portion comprising a plurality of burner bricks;
[0008] A second support portion, arranged on the first support portion, the second support portion comprising a plurality of support bricks, the support bricks and the burner bricks being alternately arranged along the length direction of the passage space structure;
[0009] A bridge brick portion, arranged on the burner brick portion and the second supporting portion, the bridge brick portion includes a plurality of bridge bricks, the bridge bricks include a bridge brick body and a first extension section arranged on at least one side of the bridge brick body along the length direction, the bridge brick body is located on the burner brick, and the first extension section abuts against the top surface of the supporting brick;
[0010] A cover plate portion, arranged above the bridge brick portion;
[0011] The first supporting portion, the burner brick portion, the second supporting portion, the bridge brick portion and the cover plate portion enclose a flame space.
[0012] In some embodiments of the present application, gaps are provided between the burner bricks and the supporting bricks, and between the burner bricks and the bridge bricks.
[0013] In some embodiments of the present application, the width of the gap is 1-10 mm.
[0014] In some embodiments of the present application, the length of the first extension segment is 5-50 mm.
[0015] In some embodiments of the present application, the burner brick includes a burner brick body and a second extension section arranged on at least one side of the burner brick body along the length direction, and the second extension section abuts against the side wall of the support brick facing away from the flame space.
[0016] In some embodiments of the present application, the length of the second extension segment is 5-50 mm.

The first extension section abuts against the top surface of the support brick. When dry masonry is used instead of wet masonry, the stability of the connection between the bridge brick and the burner brick and the support brick can still be guaranteed.

[0035] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be arbitrarily combined with each other.
[0036] like Figure 1-4 As shown, in the related art, the passage space structure includes a first support portion 1, a burner brick portion 2, a second support portion 3, a bridge brick portion 4, a cover plate portion 5 and a heat preservation portion 9, the burner brick portion 2 is arranged on the first support portion 1, and the burner brick portion 2 includes a plurality of burner bricks; the second support portion 3 is arranged on the first support portion 1, and the second support portion 3 includes a plurality of support bricks, and the support bricks and the burner bricks are alternately arranged along the length direction of the passage space structure; the bridge brick portion 4 is arranged on the burner brick portion 2 and the second support portion 3, and the bridge brick portion 4 includes a plurality of bridge bricks; the cover plate portion 5 is arranged above the bridge brick portion 4; the heat preservation portion 9 is arranged on the outer surfaces of the bridge brick portion 4 and the cover plate portion 5; the first support portion 1, the burner brick portion 2, the second support portion 3, the bridge brick portion 4 and the cover plate portion 5 enclose a flame space 6.
[0037] There are two methods of laying refractory bricks: wet laying and dry laying. In the process of laying bricks, the method of filling the brick joints with refractory mud is called wet laying; in the process of laying bricks, the method of laying bricks without using mud prepared by adding water and without any refractory mud is called dry laying. Compared with dry laying, the overall strength of wet laying structure is higher. Therefore, the burner bricks in the related art are connected with the first support part 1, the support bricks and the bridge bricks by wet laying of refractory mud.
[0038] However, after the pool kiln is put into operation, the burner bricks are easily burned out and cannot be used because they are in a high temperature environment for a long time; however, due to the limitations of the laying method of refractory bricks and the structural design of the passage space structure, it is difficult to replace the burned burner bricks individually in a hot state.
[0039] Based on this, the present application provides a passage space structure, including a first support portion, a burner brick portion, a second support portion, a bridge brick portion and a cover plate portion, wherein the first support portion, the burner brick portion, the second support portion, the bridge brick portion and the cover plate portion enclose a flame space. The burner brick portion and the second support portion are arranged on the first support portion, the bridge brick portion is arranged on the burner brick portion and the second support portion, the burner brick portion includes a plurality of burner bricks, the second support portion includes a plurality of support bricks, and the support bricks and the burner bricks are alternately arranged along the length direction of the passage space structure. The bridge bricks include a plurality of bridge bricks, the bridge bricks include a bridge brick body and a first extension section arranged on at least one side of the bridge brick body along the length direction, the bridge brick body is located on the burner brick, and the first extension section abuts against the top surface of the support brick, so that, through the structural adjustment of the bridge bricks, when dry masonry is used instead of wet masonry, the stability of the connection between the bridge bricks and the burner bricks and the support bricks can still be ensured. After the pool kiln is put into operation, when the burner bricks are burned out and cannot be used under the high temperature environment of the flame space, the burner bricks can be taken out separately in a hot state to complete the hot replacement. There is no need to hot remove the first supporting part, the second supporting part and the bridge brick part around the burner bricks, thereby avoiding the safety hazard caused by removing the refractory bricks around the burner bricks to the operation of the passage, reducing the refractory material cost and labor cost during the replacement process, and will not cause adverse effects on production.
[0040] Some specific implementation modes described below are intended to facilitate those skilled in the art to understand the present embodiment, and the present embodiment is not limited to some specific implementation modes described below.
[0041] like Figure 5-Figure 8 As shown, an exemplary embodiment of the present application provides a passage space structure, including a first support portion 1, a burner brick portion 2, a second support portion 3, a bridge brick portion 4 and a cover plate portion 5. The burner brick portion 2 is arranged on the first support portion 1, and the burner brick portion 2 includes a plurality of burner bricks; the second support portion 3 is arranged on the first support portion 1, and the second support portion 3 includes a plurality of support bricks, and the support bricks and the burner bricks are alternately arranged along the length direction of the passage space structure; the bridge brick portion 4 is arranged on the burner brick portion 2 and the second support portion 3, and the bridge brick portion 4 includes a plurality of bridge bricks, and the bridge bricks include a bridge brick body 41 and a first extension section 42 arranged on at least one side of the bridge brick body 41 along the length direction, the bridge brick body 41 is located on the burner brick, and the first extension section 42 abuts against the top surface of the support brick; the cover plate portion 5 is arranged above the bridge brick portion 4; the first support portion 1, the burner brick portion 2, the second support portion 3, the bridge brick portion 4 and the cover plate portion 5 enclose a flame space 6.
[0042] In this embodiment, by adjusting the structure of the bridge bricks, dry masonry is used instead of wet masonry, and the stability of the connection between the bridge bricks and the burner bricks and the support bricks can still be ensured. After the pool kiln is put into operation, when the burner bricks are burned out and cannot be used under the high temperature environment of the flame space 6, the burner bricks can be taken out separately in a hot state to complete the hot replacement, and there is no need to remove the first support part 1, the second support part 3, and the bridge brick part 4 around the burner bricks in a hot state, thereby avoiding the safety hazard caused by removing the refractory bricks around the burner bricks to the passage operation, reducing the refractory material cost and labor cost during the replacement process, and will not cause adverse effects on production.
[0043] The first extension section 42 can be arranged only on one side of the bridge brick body 41, or on both sides of the bridge brick body 41.

[0052] In this embodiment, by providing the second extension section 22 on the burner brick body 21, a limiting effect can be achieved to prevent the burner brick from being excessively inserted into the flame space 6. The second extension section 22 can be provided on only one side of the burner brick body 21, or on both sides of the burner brick body 21.
[0053] In one embodiment, the length of the second extension section 22 is 5-50 mm.
[0054] Exemplarily, the length of the second extension section 22 is 5 mm, 10 mm, 20 mm, 30 mm, 40 mm or 50 mm.
[0055] In one embodiment, the passage space structure further includes a heat-insulating cotton layer 8 arranged in the gap 7 .
[0056] In this embodiment, by arranging the heat-insulating cotton layer 8 in the gap 7, the passage space structure can be insulated to prevent the flame in the flame space 6 from escaping from the gap 7. For example, the heat-insulating cotton layer 8 can be ceramic fiber paper.
[0057] In one embodiment, the thickness of the thermal insulation cotton layer 8 is 1-10 mm.
[0058] In this embodiment, the thickness of the thermal insulation cotton layer 8 corresponds to the width of the gap 7. Exemplarily, the thickness of the thermal insulation cotton layer 8 is 1 mm, 2 mm, 5 mm or 10 mm.
