Description

Technical Field

[0001] This utility model relates to the technical field of blast furnace dust removal fans, specifically a connecting device for a blast furnace dust removal fan. Background Technology

[0002] Blast furnace dust removal is a key environmental protection step in steel production. The dust generated during blast furnace production contains harmful substances such as heavy metals and tar. Direct emission would seriously pollute the air. By using the high-speed rotation of the impeller of the blast furnace dust removal fan to generate negative pressure, iron-containing dust and tar particles generated in areas such as the blast furnace tapping area and furnace top are sucked into the dust removal system. The collection efficiency can reach over 99%. Therefore, the blast furnace dust removal fan is a key piece of equipment used in steel smelting to purify blast furnace gas and flue dust in the tapping area. During installation, the outlet of the centrifugal induced draft fan is directly connected to the inlet of the dust collector through a flange, and the bolts are tightened evenly with a torque wrench.

[0003] Currently, after the ventilation duct and fan inlet are fixed with flanges and threads, support frames or hangers are usually installed to support the ventilation duct to ensure its stability. The support frames are usually fixed to the ventilation duct with multiple sets of screws. If the ventilation duct is damaged, the support frame needs to be disassembled separately with tools before the ventilation duct can be repaired, which is inconvenient.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0025] like Figure 1As shown, a blast furnace dust removal fan connection device includes a fan body 1 and a mounting base 2 fixedly installed at one end of the fan body 1. An air outlet docking component 3 is provided at one end of the fan body 1. A connecting component 4 is threadedly fixedly installed at one end of the air outlet docking component 3. A support component 5 is fixedly installed on the outer wall of the connecting component 4. The support component 5 is configured to support the connecting component 4 under load. Suspension components 6 are fixedly installed on both sides of the upper end of the support component 5. The suspension components 6 are configured to hoist and fix the support component 5.

[0026] The support component 5 includes an installation mechanism 51 and a cross brace mechanism 52 that is fixedly installed at the lower end of the installation mechanism 51. The combination of the installation mechanism 51 and the cross brace mechanism 52 is suitable for supporting the connecting component 4.

[0027] The suspension assembly 6 includes an extension mechanism 61 and a built-in threaded sleeve 62 that is threaded to the upper end of the extension mechanism 61. The built-in threaded sleeve 62 is fixedly installed on the support frame or the top of the wall by screws according to the installation requirements.

[0028] like Figure 2 As shown, the installation mechanism 51 includes an extension horizontal plate 511 and vertical plates 512 that are fixedly installed on both sides of the lower end of the extension horizontal plate 511 at equal intervals. The extension horizontal plate 511 is located at the upper end of the ventilation duct 41, and the vertical plates 512 are located on both sides of the ventilation duct 41. A through groove 513 is provided in the middle of the lower end of the vertical plate 512.

[0029] The cross bracing mechanism 52 includes a T-shaped insertion block 521 and a magnetic slot 522 opened in the middle of one end of the T-shaped insertion block 521. A corresponding magnetic block 523 is magnetically connected in the inner cavity of the magnetic slot 522. The T-shaped insertion block 521 drives the corresponding magnetic block 523 to be limited and installed in the inner cavity of the through slot 513.

[0030] like Figure 4 As shown, the extension mechanism 61 includes a lifting rod 611 and a circular groove 612 opened in the middle of the upper end of the lifting rod 611. A rotating T-post 613 is movably installed in the inner cavity of the circular groove 612. An elastic element 614 is fixedly installed at the upper end of the rotating T-post 613. A threaded rod 615 is fixedly installed at the upper end of the elastic element 614. The threaded rod 615 is threadedly installed in the inner cavity of the built-in threaded sleeve 62. The built-in threaded sleeve 62 is designed to be suitable for lifting and supporting the lifting rod 611.

[0031] Connecting columns 616 are fixedly installed around the lower end of the outer wall of the threaded rod 615. A rotating ring 617 is fixedly installed on the outer surface of the connecting column 616. The rotating ring 617 is designed to drive the connecting column 616 and the threaded rod 615 to rotate, so as to facilitate the installation and disassembly of the threaded rod 615.

[0032] In this application, after the ventilation duct 41 and the fan outlet are fixed, the extension horizontal plate 511 is moved to the upper end of the ventilation duct 41. Simultaneously, vertical plates 512, linearly and equally spaced on both sides of the lower end of the extension horizontal plate 511, are installed on both sides of the outer wall of the ventilation duct 41. After the upper end of the built-in threaded sleeve 62 is pre-fixed to the top of the wall with screws, rotating the rotating ring 617 drives the threaded rod 615 and the lower end cavity of the built-in threaded sleeve 62 to be threadedly fixed. Simultaneously, during the rotation of the threaded rod 615, the elastic element 614 and the rotating T-post 613 will rotate together. The movement causes the rotating T-post 613 to rotate within the cavity of the circular groove 612. After the threaded rod 615 and the built-in threaded post sleeve 62 are threaded and fixed, the extension horizontal plate 511 is supported and fixed. Then, the T-shaped insert block 521 is inserted into the cavity of the through groove 513 and magnetically attracted to the cavity of the magnetic slot 522 by the corresponding magnetic block 523. This allows the T-shaped insert block 521 to support the lower end of the ventilation duct 41. This design also makes it convenient to remove the extension horizontal plate 511 by simply pulling the corresponding magnetic block 523 out of the cavity of the magnetic slot 522.

[0033] like Figure 3 As shown, the air outlet docking assembly 3 includes a concave block 31 and a through groove 32 opened in the middle of the upper end of the concave block 31. Top threaded rods 33 are fixedly installed on both sides of the upper end of the bottom surface of the through groove 32.

[0034] The connecting component 4 includes a ventilation duct 41 and a hollow frame 42 fixedly installed at one end of the ventilation duct 41. The hollow frame 42 is installed into the lower through groove 32 from the upper end and is movably installed in the inner cavity of the lower through groove 32. Through circular grooves 43 are respectively opened on both sides of the upper end of the hollow frame 42. The top threaded rod 33 is movably installed in the inner cavity of the through circular groove 43 and is fixed by the threaded nut at the upper end of the slot of the through circular groove 43, so as to press and fix the hollow frame 42 in the inner cavity of the lower through groove 32.

[0035] In this application, a hollow frame 42, fixed at one end of the ventilation duct 41, is inserted from the upper end of the lower through groove 32, so that the top threaded rod 33 is inserted into the inner cavity of the through circular groove 43. The upper end of the top threaded rod 33 is then pressed into the upper end of the slot of the through circular groove 43 by a nut for fixation. Thus, the hollow frame 42 is fixedly installed in the inner cavity of the lower through groove 32. With this arrangement, when the ventilation duct 41 is damaged and needs to be disassembled, it is only necessary to remove the nut threaded to the upper end of the top threaded rod 33, making installation and disassembly convenient.

[0036] In summary: Through the combined use of the ventilation duct 41, the extension horizontal plate 511, the vertical plate 512, the built-in threaded sleeve 62, the rotating ring 617, the threaded rod 615, the elastic element 614, the circular groove 612, the corresponding magnetic block 523, and the magnetic slot 522, the T-shaped insert block 521 supports the lower end of the ventilation duct 41. When disassembling the extension horizontal plate 511, the corresponding magnetic block 523 can be pulled out from the inner cavity of the magnetic slot 522. Through the combined use of the ventilation duct 41, the hollow frame 42, the lower through groove 32, the top threaded rod 33, and the through circular groove 43, the ventilation duct 41 can be disassembled by removing the nut threaded to the upper end of the top threaded rod 33.
