Description

Technical Field

[0001] This invention relates to the field of steelmaking production technology, and in particular to a method for arranging and connecting dust removal pipes through lattice columns. Background Technology

[0002] Steelmaking plant buildings often have numerous dust collection pipes arranged longitudinally. These pipes are characterized by their large diameter and heavy load. It's generally difficult for them to pass through the gaps between the lintels of lattice columns. Typically, the pipes are placed along the sides of the columns, supported by additional supports underneath. The disadvantages of this method are that the pipes occupy a large amount of space and require separate supports and foundations. Another method involves directly supporting the pipes with tripods mounted on the column. This method also requires a large amount of space, and due to the heavy load, the pipe load is eccentric, which is detrimental to the stress on the column.

[0003] Therefore, based on years of experience and practice in related industries, the inventor proposes a method for arranging and connecting dust removal pipes through lattice columns to overcome the shortcomings of existing technologies. Summary of the Invention

[0004] The purpose of this invention is to provide a method for arranging and connecting dust removal pipes through lattice columns, which solves the problems of large space occupation and unfavorable stress of dust removal pipes. In this invention, the spatial arrangement of dust removal pipes is reasonable and saves space; the stress is reasonable and does not generate eccentric bending moment; the structure is simple, does not require additional foundations, has low cost, and is convenient for construction.

[0005] The objective of this invention is achieved as follows: a method for arranging dust removal pipes through lattice columns, comprising: adjusting the grid size of the lattice columns to form connecting grids corresponding to the dust removal pipes on both sides of the lattice columns; fixing a connecting structure that can seal and transitionally connect the dust removal pipes on both sides within the connecting grids, wherein the connecting structure is provided with a lacing channel that can seal through oblique lacing strips, and the two ends of the connecting structure extend out of the column flanges and are fixedly connected to the dust removal pipes on both sides.

[0006] In a preferred embodiment of the present invention, within the connected area, body steel plates are respectively connected around the inner perimeter of the column flange, and each of the body steel plates is sealed and enclosed to form the connected structure with a rectangular cross-section.

[0007] In a preferred embodiment of the present invention, the ends of the connecting structure are provided with a variable cross-section, and the cross-section changes from rectangular to circular.

[0008] In a preferred embodiment of the present invention, a connecting flange is provided at the end of the connecting structure, and the connecting flange is sealed and conductively connected to the dust removal pipe.

[0009] In a preferred embodiment of the present invention, the end of the connecting structure is sealed and connected to the dust removal pipe by welding.

[0010] In a preferred embodiment of the present invention, the inner sealing plate is sealed around the perimeter of the lacing channel.

[0011] In a preferred embodiment of the present invention, a conductive pipe is fixedly connected to the inner side of the flange of the column in the connected area. The conductive pipe constitutes the connected structure, and the end of the conductive pipe is sealed and conductively connected to the dust removal pipe.

[0012] The object of the present invention can also be achieved as follows: a connecting structure for dust removal pipes passing through lattice columns, used in the aforementioned arrangement method of dust removal pipes passing through lattice columns, wherein the connecting structure is set in the grid corresponding to the dust removal pipe, the connecting structure is hollow, and both ends of the connecting structure extend out of the column flanges and are sealed and connected to the dust removal pipes on both sides; the connecting structure is provided with a lacing channel, and the lacing channel is sealed and covered by an inner sealing plate.

[0013] In a preferred embodiment of the present invention, the connecting structure is formed by a body steel plate connected around the inner perimeter of the column flange.

[0014] In a preferred embodiment of the present invention, connecting flanges for sealing the connection of the dust removal pipe are provided at both ends of the connecting structure.

[0015] As described above, the arrangement method and connection structure of the dust removal pipe through the lattice column of the present invention have the following beneficial effects:

[0016] In this invention, a connecting structure fixed within the connecting grid is used to connect dust removal pipes that need to pass through the space between the lattice columns. The connecting structure can meet the requirements of sealing the dust removal pipes and allows the oblique strips to pass through in a sealed manner, which solves the difficulty of pipes passing through the oblique strip lattice columns, reduces the space occupied by the pipes, and increases the effective usable area of ​​the factory building.

[0017] The interconnected structure directly transfers the pipe load to the column members of the lattice column, resulting in a reasonable stress distribution and no eccentricity to the lattice column, thereby reducing the column cross-section. At the same time, the absence of pipe supports and foundations reduces the amount of material and saves costs.

[0018] This invention is simple to construct and saves time. Attached Figure Description

[0031] like Figure 1 , Figure 2 , Figure 3As shown, the present invention provides a method for arranging dust removal pipes through lattice columns. Specifically, the method includes: adjusting the grid dimensions of the lattice column 1 (factory column) according to the arrangement location, installation requirements, and specifications of the dust removal pipe 2 (adjusting the height of each grid using horizontal crossbars 13) to form a connecting grid 11 corresponding to the dust removal pipes 2 on both sides, with elevations aligned with the dust removal pipes 2; fixing a connecting structure 3 within the connecting grid 11 that can seal and transitionally connect the dust removal pipes 2 on both sides; providing a sealing channel on the connecting structure 3 for passing through oblique crossbars 12 (in the prior art, a reinforcing structure between lattice columns 1, where oblique crossbars typically reduce the pipe space within the grid); and fixing the two ends of the connecting structure 3, extending beyond the column flanges, to the dust removal pipes 2 on both sides.

[0032] This invention provides a method for arranging dust removal pipes through lattice columns. A connecting structure fixed in the connecting area connects the dust removal pipes that need to pass through the space between the lattice columns. The connecting structure can meet the requirements of sealing the dust removal pipes and allows the oblique strips to pass through in a sealed manner. This solves the difficulty of pipes passing through oblique strip lattice columns, reduces the space occupied by the pipes, and increases the effective usable area of ​​the factory building.

[0033] The interconnected structure directly transfers the pipe load to the column members of the lattice column, resulting in a reasonable structural stress distribution. It does not cause eccentricity to the lattice column (factory column), thereby reducing the column cross-section. At the same time, there are no pipe supports and foundations, reducing the amount of materials and saving costs.

[0034] This invention is simple to construct and saves time.

[0035] Example 1

[0036] like Figure 1 , Figure 2 , Figure 3 As shown, within the connected grid 11, the inner sides of the column flanges are connected to the main body steel plates 31, and the main body steel plates 31 are sealed together to form a connected structure 3 with a rectangular cross-section.

[0037] Furthermore, the end of the connecting structure 3 is designed with a variable cross-section, changing its cross-section from rectangular to circular, which facilitates connection with the dust removal pipe 2 with a circular cross-section.

[0038] The connection between the connecting structure 3 and the dust removal pipe 2 adopts a detachable flange connection:

[0039] A connecting flange 32 is provided at the end of the connecting structure 3, and the connecting flange 32 is sealed and conductively connected to the dust removal pipe 2. A pipe flange 21 is correspondingly provided at the end of the dust removal pipe 2 to be connected, and the connecting flange 32 is sealed and connected to the pipe flange 21 for easy construction.

[0040] When the diagonal bracing strip 12 is installed in the connecting section 11 (the section corresponding to the dust removal pipe), a bracing strip channel is provided on the connecting structure, and the inner sealing plate 33 is sealed around the bracing strip channel. The inner sealing plate 33 wraps around the diagonal bracing strip 12 to provide protection and prevent corrosion from the gas medium inside the pipe.

[0041] Example 2

[0042] Within the connected grid 11, the inner sides of the column flanges are connected to the main body steel plates 31, and the main body steel plates 31 are sealed together to form a connected structure 3 with a rectangular cross-section.

[0043] Furthermore, the end of the connecting structure 3 is designed with a variable cross-section, changing its cross-section from rectangular to circular, which facilitates connection with the dust removal pipe 2 with a circular cross-section.

[0044] The connection between the connecting structure 3 and the dust removal pipe 2 is a welded fixed connection.

[0045] The end of the connecting structure 3 is sealed and connected to the dust removal pipe 2 by welding.

[0046] When the diagonal bracing strip 12 is installed in the connecting section 11 (the section corresponding to the dust removal pipe), a bracing strip channel is provided on the connecting structure, and the inner sealing plate 33 is sealed around the bracing strip channel. The inner sealing plate 33 wraps around the diagonal bracing strip 12 to provide protection and prevent corrosion from the gas medium inside the pipe.

[0047] Example 3

[0048] Within the connecting grid 11, a connecting pipe is fixedly connected to the inner side of the column flange. The diameter of the connecting pipe is selected to a reasonable size and is welded to the inner side of the column flange on all four sides to achieve a stable connection. The connecting pipe forms a connecting structure, and the end of the connecting pipe is sealed and connected to the dust removal pipe 2.

[0049] The two ends of the guide pipe are connected to the dust removal pipe 2 by a detachable flange connection or by a welded fixed connection.

[0050] When the diagonal bracing strip 12 is installed in the connecting section 11 (the section corresponding to the dust removal pipe), a bracing strip channel is provided on the connecting structure, and the inner sealing plate 33 is sealed around the bracing strip channel. The inner sealing plate 33 wraps around the diagonal bracing strip 12 to provide protection and prevent corrosion from the gas medium inside the pipe.

[0051] like Figures 1 to 3As shown, the present invention provides a connecting structure for a dust removal pipe passing through a lattice column, used in the aforementioned arrangement method of dust removal pipe passing through a lattice column. The connecting structure 3 is set in the grid corresponding to the dust removal pipe 2. The connecting structure 3 is hollow. Both ends of the connecting structure 3 extend out of the column flanges and are sealed and connected to the dust removal pipes 2 on both sides. A lacing channel is provided on the connecting structure 3, and the inner sealing plate 33 is sealed around the lacing channel.

[0052] Furthermore, the connecting structure 3 is enclosed by a main body steel plate 31 connected around the inner side of the column flange.

[0053] Furthermore, the cross-sections at both ends of the connecting structure 3 are circular, while the cross-section between the two ends is rectangular. The transition from square to round at both ends of the connecting structure 3 facilitates connection with the dust collection duct.

[0054] Furthermore, connecting flanges 32 for sealing the connection of dust removal pipes are provided at both ends of the connecting structure 3. Correspondingly, pipe flanges 21 are provided at the ends of the dust removal pipes 2 to be connected, and the connecting flanges 32 and pipe flanges 21 are sealed together for easy construction.

[0055] As described above, the arrangement method and connection structure of the dust removal pipe through the lattice column of the present invention have the following beneficial effects:

[0056] In this invention, a connecting structure fixed within the connecting grid is used to connect dust removal pipes that need to pass through the space between the lattice columns. The connecting structure can meet the requirements of sealing the dust removal pipes and allows the oblique strips to pass through in a sealed manner, which solves the difficulty of pipes passing through the oblique strip lattice columns, reduces the space occupied by the pipes, and increases the effective usable area of ​​the factory building.

[0057] The interconnected structure directly transfers the pipe load to the column members of the lattice column, resulting in a reasonable structural stress distribution. It does not cause eccentricity to the lattice column (factory column), thereby reducing the column cross-section. At the same time, there are no pipe supports and foundations, reducing the amount of materials and saving costs.
