Description

Technical Field

[0001] The invention relates to the technical field of glass melting furnaces, and in particular to a glass melting furnace tie rod structure and a construction method thereof. Background Art

[0002] Glass melting furnace is a large thermal equipment. To ensure that the melting furnace remains stable and reliable during long-term hot operation, in addition to the reasonable configuration of refractory materials in various parts, a reasonable and safe steel structure must be matched with it. The large arch of the melting part of the horizontal flame glass melting furnace generally adopts a double-braced structure, which is mainly composed of a brace, a column, a one-way thrust ball bearing and a nut. The double-braced structure mainly resists the horizontal thrust generated by the large arch to maintain the thermal stability and safety of the large arch.

[0003] When a glass melting furnace is cold-modified after running for a period of time, there is often a requirement to increase the tonnage. The increase in the width of the tank will increase the height of the arch and the height of the breast wall. This causes the original column height to be unable to meet the requirements for arranging double tie bars. If new columns are made, it runs counter to the concept of rationality and economy in the transformation process. In view of the above-mentioned problems in the transformation process, the present invention aims to provide a glass melting furnace tie bar structure and a construction method thereof to solve the problem that the original column height after the transformation cannot meet the requirements for arranging double tie bars.

Figure 1 ; Figure 4 This is a schematic diagram of the structure of the brace support in the present invention. Figure 2 , see Figures 1 to 4As shown, a preferred embodiment is shown, which shows a glass melting furnace tie rod structure, including a melting part column 1, a breast wall 2, a large crown 3, a tie rod 4, a nut 5, a one-way thrust ball bearing 6 and a tie rod support 7. A large crown 3 and a breast wall 2 are provided between the two melting part columns 1. The two ends of the large crown 3 are connected to the two breast walls 2, and the two breast walls 2 are connected to the melting part column 1. The upper ends of the two melting part columns 1 are provided with a tie rod support 7. The two ends of the tie rod 4 are connected to the two tie rod supports 7 through nuts 5. A one-way thrust ball bearing 6 is also provided on the tie rod 4, and the one-way thrust ball bearing 6 is located between the tie rod support 7 and the nut 5. When a glass melting furnace is cold-modified, there is often a requirement to increase the tonnage. Generally, the purpose of increasing the melting capacity is achieved by increasing the pool width and the length of the melting part. The increase in the pool width will increase the height of the large crown 3, and the height of the breast wall 2 will also increase accordingly. This results in that the original melting part column 1 cannot meet the requirement of arranging double tie bars. In this embodiment, the upper tie bars of the original melting part column 1 are used as the modified lower tie bars, and tie bar supports 7 are welded on the top of the original melting part column 1 to install the upper tie bars, thereby solving the problem that the original column height cannot meet the requirement of arranging double tie bars after modification, and the original column is reused, thus achieving a significant reduction in modification cost.

The support plate 75 is located between the two triangular plates 73, and the support plate 75 is directly opposite to the vertical plate 72. The vertical plate 72 and the support plate 75 are used to support the brace 4, and the bottom plate 71, the vertical plate 72, the triangular plate 73, the rib plate 74 and the support plate 75 can be integrally formed or welded.

[0029] Further, as a preferred embodiment, a mounting hole 76 is provided on the vertical plate 72, and the upper surface of the support plate 75 is flush with the plane where the lower inner wall of the mounting hole 76 is located. The mounting hole 76 runs through the vertical plate 72, and the mounting hole 76 is used to install the end of the pull rod 4. The end of the pull rod 4 can pass through the mounting hole 76, and then the lower surface of the pull rod 4 will be supported on the upper surface of the support plate 75, so as to support the pull rod 4.

[0030] By providing the one-way thrust ball bearing 6 and the nut 5 , the brace 4 and the brace support 7 can be fixed together.
