[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example:

[0030] See also Figure 1-9 A dust removal device for blast furnace iron tapping includes a shielding component for shielding the iron tapping place and a negative pressure component for dust collection.

[0031] The mask assembly includes a fixed seat 1, a sliding plate 3, a telescopic driving part 4 and a mask tube 5. A plurality of telescopic driving parts 4 are installed on the fixed seat 1. The output shaft of the telescopic driving part 4 is connected to the sliding plate 3. A plurality of mask tubes 5 are connected to the sliding plate 3.

[0032] The negative pressure assembly includes a support plate 2, an air guide box 6, a delivery pipe 7, a transmission pipeline 10 and a negative pressure device 11. Several negative pressure devices 11 are connected to the support plate 2. The mask tube 5 is connected to several air guide boxes 6. A plurality of delivery pipes 7 are connected to the mask tube 5. The delivery pipe 7 is communicated with the air guide box 6. The air suction end of the air guide box 6 and the negative pressure device 11 is communicated through the transmission pipeline 10. The transmission pipeline 10 can be folded. The transmission pipeline 10 can be optionally covered with silicone glass fiber cloth and supported by spiral steel wire. As another application form, nano-ceramic aerogel and highly flexible hydroxyapatite "refractory paper" can be selected. As another application form, double-layer aluminum foil air ducts and aluminum foil composite air ducts with aluminum foil bonded to PVC or glass fiber cloth can be selected. A plurality of bendable folding parts are arranged in the middle of the transmission pipeline 10, which is a common foldable pipeline structure. The mask tube 5 and the iron outlet A certain gap is set between the areas where iron can flow down to reduce direct contact between the iron material and the conveying pipe 7. The telescopic drive part 4 is one of a cylinder, a hydraulic cylinder and an electric cylinder. The negative pressure device 11 is an exhaust fan, such as a WQE7-7.5kw high-temperature fan. It is preferred to connect the discharge port of the negative pressure device 11 with the dust collector, and protect the iron outlet through the mask tube 5. Multiple air guide boxes 6 on the mask tube 5 simultaneously transmit debris in the surrounding area, and generate negative pressure through the negative pressure device 11. The negative pressure device 11 transmits debris through the transmission pipeline 10, and transmits debris at the iron outlet through multiple air guide boxes 6, which is beneficial to improve the efficiency of discharging dust and debris, and improve the protection effect of the iron outlet. The mask tube 5 can extend to protect the area where the discharged material is contained at the iron outlet, reduce the scattering of debris at the transmission point, improve the protection effect of the iron outlet, and is beneficial to collect dust.

[0033] Reference Figure 3 The mask assembly also includes a slider 12 and a guide rail 13. A plurality of guide rails 13 are connected to the fixed seat 1. The slider 12 is slidably connected to the guide rail 13. The slider 12 is connected to the sliding plate 3. Each guide rail 13 is supported by the fixed seat 1. The slider 12 is arranged on the guide rail 13, and the slider 12 slides on the guide rail 13, thereby improving the guiding effect of the sliding plate 3.

[0034] Reference Figure 1 There are two mask assemblies, which are arranged opposite to each other. The mask tubes 5 of the two mask assemblies can surround the iron outlet. Through the relative arrangement of the two mask tubes 5, the positions of the mask tubes 5 can be adjusted on both sides, which is beneficial to adjust the mask tubes 5 and improve the positioning and guiding effects of the mask tubes 5.

[0035] Reference Figure 1 The shield tube 5 is semi-cylindrical, which is beneficial to protecting the iron-out location, and can protect and transport debris in different directions in the surrounding area. The cylindrical shield tube 5 can install the conveying pipe 7 in different directions.

[0036] Reference Figure 2The negative pressure assembly also includes a sealing gasket 8 and an adapter plate 9. The shield tube 5 is connected to a sealing gasket 8, and a plurality of adapter plates 9 are connected to the sealing gasket 8. The adapter plates 9 are arranged at opposite ends of the two shield tubes 5. The adapter plates 9 are preferably made of graphite and ceramic. Through the arrangement of the adapter plates 9, the contact points of the shield tubes 5 are protected, which is beneficial to improving the sealing effect of the contact points of the shield tubes 5.

[0037] Reference Figure 2 The conveying pipe 7 includes a baffle 14. A plurality of baffles 14 are arranged on the conveying pipe 7. The baffles 14 can block some large debris from entering the transmission channel, thereby reducing the blockage at the transmission point.

[0038] When in use, the whole is installed at the iron outlet so that the shielding tube 5 can cover the iron outlet and the feed port of the container storing molten iron. When the molten iron is transported, the negative pressure device 11 is turned on to absorb the debris and harmful gases in the surrounding area. When the container storing molten iron needs to be inspected and moved, the telescopic drive part 4 drives the sliding plate 3 and the shielding tube 5 to move to make more space.
