[0004] To solve the above technical problems, the technical solution adopted by this utility model is as follows:

Detailed Implementation

[0022] To enable those skilled in the art to better understand this utility model, the present utility model will be further described clearly and completely below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0023] Taking a coking coal preparation project undertaken by the applicant as an example, the core part of the project is the coal tower at an elevation of EL+58.9m. The project has a total of 4 coke ovens, with each pair of coke ovens sharing one coal tower. Since the coke ovens are designed with SCP coal conveying and tamping integrated trolleys, the coal tower does not have a tamping machine. To increase coal capacity, 12 hyperbolic funnels are installed. These hyperbolic funnels consist of an upper brick structure and a lower steel structure. These lower steel funnels are installed between the coal tower elevations of EL+24.780m and 30.280m, arranged in a 1-3 axis layout, totaling 4 rows and 3 columns, for a total of 12 hyperbolic steel funnels. In this design, the upper diameter of the steel funnel is 4.086m, the lower diameter is 1m, and the overall height reaches 8m. In addition, the bevel lengths of the steel funnels are 718mm and 1136mm, respectively, while the corresponding bevel angles are 32° and 68°. These precise dimensional designs ensure the efficient operation of the steel funnels in the coal tower.

[0024] A typical embodiment of this utility model provides an installation structure for the lower steel funnel of a hyperbolic funnel on a coal tower in a coking plant, which consists of a pre-embedded annular iron piece 1 and a pre-embedded plate 2.

[0025] like Figure 1 As shown, the embedded annular iron part 1 is a hollow frustum structure, which is fixedly installed at the reserved opening of the steel funnel of the frame beam. The lower part of the embedded annular iron part 1 is welded to the steel funnel 3.

[0026] like Figure 3 , 4 As shown, the embedded plate 2 serves as a supporting component for the embedded annular iron piece 1, and is installed around the top beam of the concrete lower opening of the steel funnel. Multiple embedded plates 2 surround and are fixed to the outer wall of the embedded annular iron piece 1, and are embedded within the concrete structure of the frame beam 3. Embedded reinforcing bars are vertically installed on the embedded plate 2. The embedded plate 2 enhances the load-bearing capacity of the embedded annular iron piece 1 on the overall lower part of the steel funnel.

[0027] The hyperbolic steel funnel is fabricated in sections on the ground and the sections are assembled and installed on the ground. After assembly, the steel funnel is hoisted to the lower part of the pre-embedded annular iron part 1. During installation, only one weld is needed to connect the steel funnel to the pre-embedded iron part at the funnel opening, which significantly improves the installation efficiency.

[0028] like Figure 2As shown, in a preferred embodiment, based on the above embodiments, the hyperbolic steel funnel installation structure further includes longitudinal reinforcing bars 5 and circumferential reinforcing bars 6 for reinforcing the embedded annular iron component 1. Several anchoring holes are opened on the side wall of the embedded annular iron component 1. The circumferential reinforcing bars 6 are inserted into the concrete structure of the frame beam from the anchoring holes towards the reserved opening of the frame beam. The longitudinal reinforcing bars 5 are inserted into the concrete structure of the frame beam on the outside of the side wall of the embedded annular iron component 1 and connected to the annular reinforcing bars 6. The longitudinal reinforcing bars 5 and circumferential reinforcing bars 6 can further improve the load-bearing capacity of the embedded annular iron component 1 on the steel funnel.

[0029] The bottom of the embedded plate is fixed with a stiffening plate 7, and the stiffening plate 7 is welded evenly to the embedded annular iron piece 1.

[0030] like Figure 5 , Figure 6 As shown, in a preferred embodiment, the hyperbolic steel funnel installation structure includes multiple temporary constraint devices 8 fixed to the outer wall of the circumferential weld 9. The temporary constraint device includes an upper fixing part 800, a lower fixing part 801, and a connecting bolt 802. The upper fixing part 800 is connected to the outer wall of the pre-embedded annular iron part 1, the lower fixing part 801 is connected to the outer wall of the steel funnel 3, and the connecting bolt 802 is connected between the upper fixing part 800 and the lower fixing part 801.

[0031] According to this embodiment, a temporary restraint device 8 is used on the outer wall of the circumferential weld 9 to prevent welding deformation. During welding, the inner wall is welded by unidirectional bevel penetration argon-electric welding, and the outer wall is repaired by arc welding. The weld joints of the inner and outer walls are ground to form double-sided shapes.

[0032] The scope of protection claimed by this utility model is not limited to the specific embodiments described above. For those skilled in the art, this utility model can have various modifications and alterations. Any modifications, improvements and equivalent substitutions made within the concept and principles of this utility model should be included within the protection scope of this utility model.
