Description

Technical Field

[0001] This utility model belongs to the technical field of metallurgical ironmaking equipment, and relates to a tuyere platform suction beam, which is mainly used in the ironmaking tapping field system. Background Technology

[0002] In the blast furnace ironmaking process, the tapping stage is crucial. When blast furnace iron is tapped, molten slag and iron are ejected from the taphole, generating a large amount of high-temperature dust and flue gas. These high-temperature pollutants make the environment in the taphole area extremely harsh, not only causing accelerated damage to equipment due to prolonged exposure to high temperatures and dust, increasing equipment maintenance costs and downtime risks, but also posing a significant threat to worker safety and health. To improve this situation, dust hoods and other ventilation and dust removal facilities are typically installed in the tapping area on the platform. These facilities effectively reduce the spread of smoke and dust, lower the temperature in the area, thereby improving the working environment in front of the furnace and ensuring the safety of equipment and personnel.

[0003] From the site layout, the main tapping channel is directly in front of the tapping hole, and key furnace-front equipment such as mud guns and tapping machines are arranged on both sides or one side of the main tapping channel. In order to achieve better dust removal effect and avoid occupying valuable operating space in front of the furnace, the dust removal hood is generally arranged between the furnace-front equipment on both sides of the tapping hole and the blast furnace body.

[0004] However, numerous challenges arise during the actual layout process. On one hand, the dense equipment layout in this area, with numerous devices within the furnace and tapping systems, makes the space already extremely congested, significantly hindering the installation of dust hoods. On the other hand, the limited height of the space between the tuyeres and the tapping platform, located above the tapping platform, results in exceptionally narrow spaces on both sides of the taphole. In such circumstances, finding suitable locations for dust hoods is often difficult, and even if successful, new problems arise. Due to the limited space, the dust collection pipes connecting the hoods may be too close to the equipment. When high-temperature dust passes through these pipes, it can have a baking effect on surrounding equipment. Prolonged exposure to this environment can severely impact equipment lifespan, increase the probability of equipment failure, and negatively affect the stable operation of the blast furnace. Therefore, solving the problem of the rational layout of dust collection equipment in the taphole area has become a critical technical challenge that urgently needs to be addressed in blast furnace ironmaking. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a suction beam for an air vent platform to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A suction beam for an air vent platform is provided. As part of the air vent platform, the suction beam is arranged near the iron opening of the air vent platform. It includes a box beam and an external dust removal pipe communicating with the inner cavity of the box beam. The box beam is provided with a suction port to suck away high-temperature smoke and dust. The external dust removal pipe is connected to an external dust removal system.

[0008] Furthermore, the box girder is arranged at the bottom of the air vent platform on both sides of the iron outlet, and is designed with structural reinforcement measures to serve as the structural beam of the air vent platform to bear the platform load.

[0009] Furthermore, the structural reinforcement measures include setting reinforcing ribs on the outside of the box girder or increasing the thickness of the steel plate.

[0010] Furthermore, an air intake is provided at the bottom of the box girder.

[0011] Furthermore, an air intake is provided on the side of the box girder near the iron tap.

[0012] Furthermore, one end of the external dust removal pipe is connected to the side or bottom of the box girder, and the other end is connected to an external dust removal system.

[0013] Furthermore, the box girder adopts a rectangular steel structure.

[0014] Furthermore, the outer wall of the box girder is provided with thermal insulation material. Specifically, the thermal insulation material can be ceramic fiber, used to prevent high-temperature smoke and dust from generating heat radiation on the girder structure and above the air vent platform.

[0015] Furthermore, the air intake is embedded with a high-temperature resistant filter. This high-temperature resistant filter can be quickly disassembled and replaced to prevent problems such as dust accumulation and blockage in the pipes.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model proposes a suction beam for an air vent platform, cleverly integrating dust removal functionality into the structural beam of the air vent platform. Located at the bottom of the platform near the iron tap, the suction beam consists of a box-shaped beam and an external dust removal pipe. The beam has suction ports connected to an external dust removal system. This design effectively removes high-temperature smoke and dust generated near the iron tap, maintaining the load-bearing function of the structural beam while achieving highly efficient dust removal, fully demonstrating its practicality and innovation.

[0018] 2. This tuyer platform's suction beam offers several significant advantages. First, it acts as a structural beam to bear the platform load, while simultaneously connecting to an external dust collection system via the suction inlet to quickly remove high-temperature fumes, reducing the temperature in the furnace area and improving the working environment. Second, this design eliminates the need for an additional dust hood, saving valuable space in front of the furnace and reducing investment and maintenance costs. Furthermore, the suction beam maintains a certain distance from the equipment in front of the furnace, preventing direct exposure to high-temperature fumes and extending equipment lifespan. These features collectively enhance the system's economy and reliability.

[0019] 3. In summary, the suction beam of this air vent platform, through innovative design, integrates dust removal and structural functions, achieving a comprehensive effect of environmental improvement, space optimization, and equipment protection. Without increasing complexity, it significantly improves the safety and efficiency of ironmaking tapping areas, possessing high practical value and promotion potential, and is suitable for the needs of modern industrial scenarios.

[0028] like Figure 1 and Figure 2 As shown, this embodiment provides a suction beam for an air vent platform. This suction beam, as part of the air vent platform, is installed near the iron tap to remove high-temperature fumes generated in the tap area. The suction beam includes a box-shaped beam 1 and an external dust collection pipe 2. The box-shaped beam 1 is a rectangular steel structure. Multiple longitudinal and transverse reinforcing ribs are provided on the outer side of the box-shaped beam 1. This design allows the box-shaped beam 1 not only to draw in air but also to serve as part of the load-bearing structural beam of the air vent platform, supporting the platform's weight.

[0029] The box girder 1 is equipped with suction inlets, specifically arranged as follows: a rectangular suction inlet is located at the bottom of the box girder 1; a rectangular suction inlet is also located on the side of the box girder 1 near the iron opening.

[0030] Furthermore, thermal insulation materials such as ceramic fiber are provided on the outer wall of the box girder 1 to prevent high-temperature smoke and dust from generating heat radiation on the beam structure and the area above the air vent platform.
