Abstract
Description
Technical Field
[0001] This application relates to the field of coke oven technology, and in particular to a template for preparing a coke oven flue gas channel. Background Technology
[0002] Traditional coke ovens circulate flue gas through pre-embedded lower spray pipes, risers, and gas collecting pipes in the top plate of the oven. However, the poor sealing at the connections of these pipes leads to gas leakage, environmental pollution, and ineffective heat recovery. By pre-installing flue gas channels in the concrete structure of the coke oven for flue gas circulation, secondary heat recovery can be achieved. However, current technology lacks specialized support molds for creating these flue gas channels in the concrete structure, making construction of the coke oven concrete structure inconvenient. Summary of the Invention
[0003] The purpose of this application is to provide a template for preparing a coke oven flue gas channel, so as to solve or alleviate the problems existing in the prior art.
[0004] To achieve the above objectives, this application provides the following technical solution: This application provides a template for preparing a coke oven flue gas channel, including: The wall template is provided in two parts, which are arranged vertically opposite each other, and a reinforcing component is connected between the two wall templates to limit and fasten them. The flue template includes a connecting plate and a shaped template. The connecting plate is mounted on one of the wall templates, and the shaped template is connected to the connecting plate. The shaped template has a columnar structure. A mold space for pouring concrete is formed between the wall template and the flue template.
[0005] Optionally, multiple flue templates are provided, and the length directions of the multiple flue templates are arranged parallel to each other.
[0006] Optionally, the shaping template has a columnar cavity formed inside. The columnar cavity is arranged along the length direction of the shaping template and passes through both ends of the length direction of the shaping template.

[0007] Optionally, the cross-sectional profile of the shaping template is U-shaped.
[0008] Optionally, the width of the cylindrical cavity near the opening end is greater than the width of the cylindrical cavity away from the opening end.

The width of the connecting plate is greater than the width of the shaping template, and the length of the connecting plate is the same as the length of the shaping template.
[0010] Optionally, a plurality of stiffening plates are provided inside the columnar cavity. The stiffening plates are arranged perpendicular to the length direction of the shaping template. The edges of the stiffening plates are fixedly connected to the inner wall of the columnar cavity.

Detailed Implementation
[0017] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Various examples are provided by way of explanation and not by way of limitation. In fact, those skilled in the art will understand that modifications and variations can be made to the present application without departing from the scope or spirit of the present application. For example, a feature shown or described as part of one embodiment may be used in another embodiment to produce yet another embodiment. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention should fall within the scope of protection of the embodiments of the present invention.
[0018] like Figures 1-3 As shown in the figure, this application discloses a template for preparing a coke oven flue gas passage, including a wall template 1 and a flue template 3; There are two wall formwork 1s, which are set vertically parallel and opposite to each other. A reinforcing component 2 is connected between the two wall formwork 1s to limit and fasten them. The wall formwork 1s serve as the main side formwork for concrete pouring, ensuring that the concrete wall surface remains flat and vertical after pouring.
[0019] The flue formwork 3 includes a connecting plate 31 and a shaped formwork 32. The connecting plate 31 is set on one of the wall formwork 1, and the shaped formwork 32 is connected to the connecting plate 31 by screws. The shaped formwork 32 is fixed on the connecting plate 31. The shaped formwork 32 is a columnar structure. A mold space for pouring concrete is formed between the wall formwork 1 and the flue formwork 3.
[0020] The working process and principle of the above structure are as follows: By setting up the wall template 1 and the flue template 3, a prefabrication template for concrete pouring is formed, making the preparation and construction more convenient and reducing the overall cost. The combination design of the connecting plate 31 and the fixed template 32 simplifies the complex process of traditional flue formwork, increases the formwork speed by 40%, and improves construction efficiency. The connecting plate 31, as a supporting component, enhances the compressive strength of the fixed template 32 and prevents the template from shifting during the pouring process. The dimensional error is controlled within ±2mm. After pouring, a pre-reserved flue gas channel is formed on the coke oven concrete structure. After pouring, the connecting plate 31 is disassembled to form an interval space. By laying bricks in the interval space to seal the opening 322 of the columnar cavity 321, a flue gas channel pre-embedded in the coke oven concrete wall is formed, avoiding later excavation.
[0021] In another embodiment of this application, such as Figure 1 As shown, multiple flue templates 3 are provided, and the length directions of the multiple flue templates 3 are arranged parallel to each other.
[0022] The setting of multiple flue templates 3 allows for the one-time casting of multiple flue gas channels, which facilitates the dispersed transmission of flue gas and the subsequent secondary recovery and utilization of heat energy.
[0023] In another embodiment of this application, such as Figure 1 As shown, a columnar cavity 321 is formed inside the shaping template 32. The columnar cavity 321 is arranged along the length direction of the shaping template 32 and passes through both ends of the length direction of the shaping template 32. An opening 322 is opened on the side of the shaping template 32 near the connecting plate 31 along the length direction of the shaping template 32. The opening 322 is connected to the columnar cavity 321.
[0024] The cylindrical cavity 321 reduces the weight of the shaping template 32 and also reduces the material input during the production of the shaping template 32. The opening 322 facilitates the production and shaping of the shaping template 32 and also facilitates the assembly and disassembly of the shaping template 32.
[0025] In another embodiment of this application, such as Figure 1 As shown, the cross-sectional profile of the shaping template 32 is U-shaped.
[0026] The U-shaped cross-section template 32 is lighter and easier to construct, while also saving costs.
[0027] In another embodiment of this application, such as Figure 1 As shown, the width of the cylindrical cavity 321 near the opening 322 is greater than the width of the cylindrical cavity 321 away from the opening 322.
[0028] This design is primarily to accommodate the structure of the flue gas passage.
[0029] In another embodiment of this application, such as Figure 1 As shown, the connecting plate 31 is composed of two long strips of square timber 311 arranged side by side. The two square timbers 311 are detachably connected. The cross-sectional dimensions of the square timber 311 are 70*40mm. The detachable connection methods include mortise and tenon connection, bolt connection and clamp connection. In this embodiment, mortise and tenon connection is preferred. The width of the connecting plate 31 is greater than the width of the shaping template 32, and the length of the connecting plate 31 is the same as the length of the shaping template 32.
[0030] The two long strips of square timber 311 serve as a connection structure between the template 32 and the wall template 1, as well as to seal the opening 322 of the template 32 to prevent concrete from seeping in. They also act as supporting components to enhance the compressive strength of the template 32, prevent template displacement during pouring, control the dimensional error within ±2mm, and the two square timbers 311 are detachable for easy recycling.
[0031] In another embodiment of this application, such as Figure 1 and Figure 3 As shown, multiple stiffening plates 33 are provided inside the cylindrical cavity 321. The stiffening plates 33 are 12mm thick and are arranged perpendicular to the length direction of the shaping template 32. The edges of the stiffening plates 33 are fixedly connected to the inner wall of the cylindrical cavity 321. The multiple stiffening plates 33 are evenly distributed along the length direction of the cylindrical cavity 321, and the distance between two adjacent stiffening plates 33 is 100-400mm. In this embodiment, 300mm is preferred. The spacing between adjacent stiffening plates 33 ensures that the horizontal lateral support force of the stiffening plates 33 on the shaping template 32 is maximized, and the number of stiffening plates 33 required is reduced, thereby lowering production costs.
[0032] The stiffening plate 33 improves the rigidity of the formwork 32, which can effectively resist the lateral pressure during concrete pouring. The lateral pressure bearing capacity of the formwork 32 is increased to 35kN / m², preventing deformation of the columnar cavity 321 and ensuring the flatness of the flue inner wall.
[0033] In another embodiment of this application, such as Figure 1As shown, each stiffening plate 33 has two reinforcing blocks 34 on its upper surface. The two reinforcing blocks 34 are respectively located at the open end and the closed end of the columnar cavity 321. The reinforcing blocks 34 are connected to the stiffening plate 33 by screws. The shape and contour of the reinforcing blocks 34 match the cross-sectional shape and contour of the corresponding columnar cavity 321. The setting of the reinforcing blocks 34 further enhances the horizontal support performance of the stiffening plate 33, disperses the lateral pressure of the concrete, and improves the rigidity of the formwork 32. It can effectively resist the lateral pressure during concrete pouring, increasing the lateral pressure bearing capacity of the formwork 32 to 35kN / m², preventing deformation of the columnar cavity 321, and ensuring the flatness of the inner wall of the flue.
[0034] In another embodiment of this application, such as Figure 3 As shown, each stiffening plate 33 has a reinforcing block 34 on its upper surface. The reinforcing block 34 is connected to the stiffening plate 33 by screws, and the shape and contour of the reinforcing block 34 match the cross-sectional shape and contour of the columnar cavity 321. The setting of the reinforcing block 34 further enhances the horizontal support performance of the stiffening plate 33, disperses the lateral pressure of the concrete, and improves the rigidity of the formwork 32. It can effectively resist the lateral pressure during concrete pouring, and the lateral pressure bearing capacity of the formwork 32 is increased to 35kN / m², preventing deformation of the columnar cavity 321 and ensuring the flatness of the inner wall of the flue.
[0035] In another embodiment of this application, such as Figure 4 As shown, a reinforcing block 34 is provided on the lower surface of each stiffening plate 33. The reinforcing block 34 is connected to the stiffening plate 33 by screws, and the shape and contour of the reinforcing block 34 match the cross-sectional shape and contour of the columnar cavity 321. The setting of the reinforcing block 34 further enhances the horizontal support performance of the stiffening plate 33, disperses the lateral pressure of the concrete, improves the rigidity of the formwork 32, and can effectively resist the lateral pressure during concrete pouring. The lateral pressure bearing capacity of the formwork 32 is increased to 35kN / m², preventing deformation of the columnar cavity 321 and ensuring the flatness of the inner wall of the flue.
[0036] In another embodiment of this application, such as Figure 5 As shown, each stiffening plate 33 has a reinforcing block 34 on both its upper and lower surfaces. The reinforcing block 34 is connected to the stiffening plate 33 by screws, and the shape and contour of the reinforcing block 34 match the cross-sectional shape and contour of the columnar cavity 321. The setting of the reinforcing block 34 further enhances the horizontal support performance of the stiffening plate 33, disperses the lateral pressure of the concrete, and improves the rigidity of the formwork 32. It can effectively resist the lateral pressure during concrete pouring, increasing the lateral pressure bearing capacity of the formwork 32 to 35kN / m², preventing deformation of the columnar cavity 321, and ensuring the flatness of the inner wall of the flue.
[0037] In another embodiment of this application, such as Figure 1As shown, the wall formwork 1 includes an inner wall thick formwork 11, multiple main joists 12, and multiple secondary joists 13. The secondary joists 13 are positioned between the main joists 12 and the inner wall thick formwork 11. The main joists 12 are horizontally parallel and evenly spaced, while the secondary joists 13 are vertically parallel and evenly spaced. The length directions of the main joists 12 and the secondary joists 13 are perpendicular. The main joists 12 are made of steel pipes, and the secondary joists 13 are made of square timber strips. Their perpendicular and staggered arrangement forms a grid structure, resulting in more even force distribution on the inner wall thick formwork 11 and achieving external support and fixation. The thickness of the inner wall thick formwork 11 is 12mm.
[0038] In another embodiment of this application, such as Figure 1 As shown, the reinforcing component 2 includes a reinforcing mesh (not shown) and tie rods 21. The reinforcing mesh forms the concrete reinforcement after being poured with concrete. It is positioned between two relatively vertically parallel inner wall thick formwork panels 11, providing internal support. The tie rods 21 pass vertically through the main joists 12 of the two wall formwork panels 1 and the inner wall thick formwork panels 11. Locking bolts 22 are installed at the connections between the tie rods 21 and the inner wall thick formwork panels 11 and the main joists 12. The locking bolts 22 are located on the inner and outer sides of the inner wall thick formwork panels 11, and rotate in opposite directions on the tie rods 21, thereby locking and fixing the position of the inner wall thick formwork panels 11. The locking bolts 22 are located on the outer side of the main joists 12, limiting and locking the main joists 12. The tie rods 21, in conjunction with the main keel 12, provide external support and fixation for the inner wall thick formwork 11. Combined with the internal support and fixation of the internal reinforcing steel mesh, this achieves rigid external fixation of the two inner wall thick formwork 11s, preventing bulging or misalignment. The locking bolts 22 securely fix the tie rods 21 to the inner wall thick formwork 11 and the main keel 12. Furthermore, the tensile force generated by the tie rods 21 allows the main keel 12 to press against the secondary keel 13, providing stable external support for the inner wall thick formwork 11.
