The utility model discloses blast furnace iron notch dust collector is including setting up the gas collecting channel directly over the tapping hole, the one end of gas collecting channel is passed through the trip shaft and is articulated on the platform of wind gap, the other end of gas collecting channel passes through cable suspension device to be fixed, the gas outlet of gas collecting channel is connected with the ventilation pipe through the transition pipe, wherein, transition pipe respectively with gas collecting channel, ventilation pipe can dismantle the connection. The utility model discloses blast furnace iron notch dust collector when casthouse equipment need overhaul, can detach the pipe that passes through and remove, then with the gas collecting channel upset, leave very big space for casthouse equipment's maintenance, and have advantages such as the investment economizes, operation maintenance expense is hanged down, simple structure, improved the maintenance that dust removal effect is favorable to casthouse equipment again.
Description
Technical field
This utility model relates to a kind of blast furnace ironmaking equipment dust removal field, particularly relates to a kind of blast furnace iron notch dust arrester.
Background technology
At present, the setting of dust excluding hood at metallurgy industry Iron Works tapping hole, generally use two ways:
1, top draft hood, including fixed top draft hood and cross sliding type top draft hood.Fixed top draft hood volume is big, and area coverage is wide, although can improve dust removing effects, but hamper the upkeep operation of casthouse equipment.Owing to this dust excluding hood is immovable, also hamper the repair and maintenance of equipment near ferrum mouth.Although cross sliding type top draft hood achieves dust excluding hood can move to the side of tapping hole, but cross moving track and track support beam have to be increased, track span is big, support beam volume is big, and weight increases, and takies the space of cast house, additionally realize the motor and speed reducer in the actuating device of transverse shifting due to tapping hole temperature height, dust is big, is particularly easy to break down, adds the Maintenance and Repair operation of workman the most on the contrary.
2, side-draught hood.Although side-draught hood volume is little, do not hinder ferrum mouth and the upkeep operation of neighbouring equipment thereof, but side-draught hood mode can not be installed to tapping hole both sides, do not go facing to flow of flue gas direction to trap flue dust, and need great draft towards side-draught hood direction in order to change flow of flue gas direction, therefore so also will suck substantial amounts of air, and cause dust removing effects bad.
Utility model content
For the problems referred to above, this utility model provides a kind of simple in construction, good dedusting effect, does not hinder the blast furnace iron notch dust arrester of the upkeep operation of tapping hole and neighbouring equipment thereof.
For reaching above-mentioned purpose, this utility model blast furnace iron notch dust arrester, including the gas skirt being arranged on directly over blast furnace iron notch；One end of described gas skirt is hinged on tuyere platform by trip shaft, and the other end of described gas skirt is fixed by erecting by overhang, and the gas outlet of described gas skirt is connected with ventilation duct by transition conduit；Wherein, described transition conduit two ends removably connect with described gas skirt, ventilation duct respectively.
Further, also include the transition conduit hanging apparatus of mobile transition conduit and drive described gas skirt along described trip shaft resupinate gas skirt overturning drive device.
Further, described erecting by overhang is fixed on furnace body frame.
Further, described transition conduit is bolted with described gas skirt, described ventilation duct.
Further, described transition conduit hanging apparatus is electric block.
Further, described gas skirt overturning drive device is electric block.
Further, the outside of described transition conduit is welded with lifting and buckles, and described electric block is buckled by described lifting and is connected with described transition conduit.
Further, one end that described transition conduit is connected with described ventilation duct is provided with ventilation duct connecting portion, described ventilation duct inserts one end that described transition conduit is connected with described ventilation duct, and described transition conduit is fixed with described ventilation duct by described connecting portion by connector.
This utility model blast furnace iron notch dust arrester, when casthouse equipment needs maintenance, can dismantle transition conduit and remove, then be overturn by gas skirt, leave the biggest space to the maintenance of casthouse equipment.This utility model blast furnace iron notch dust arrester overcomes side-draught hood, and to catch flue gas effect bad, and fixing cover hinders casthouse equipment upkeep operation, the shortcoming that the motor and speed reducer in the actuating device of mobile cover easily breaks down etc.；And have that reduced investment, operation maintenance expense be low, advantages of simple structure and simple, improve dust removing effects and be conducive to again the maintenance of casthouse equipment.

Detailed description of the invention
Below in conjunction with Figure of description, this utility model is further described.
Embodiment 1
The present embodiment blast furnace iron notch dust arrester includes the gas skirt 4 being located at the surface of blast furnace iron notch, one end of described gas skirt 4 is hinged on tuyere platform 6 by trip shaft 9, the other end of described gas skirt 4 is fixed on below furnace body frame by erecting by overhang 7, and the gas outlet of described gas skirt 4 is connected with ventilation duct 3 by transition conduit 2；Wherein, described transition conduit 2 is removably connected by bolt with described gas skirt 4, described ventilation duct 3 respectively.
The present embodiment blast furnace iron notch dust arrester also includes the first electric block of mobile transition conduit 2 and drives described second electric block 1, installation situation according to physical device, first electric block is arranged on the top of transition conduit and along the bracing frame of electric block, described transition conduit can be moved suitable position, described second electric block 2 can move along the space above gas skirt, second electric block 1 moves near tuyere platform 6, and gas skirt is flipped up along described trip shaft.
The present embodiment blast furnace iron notch dust arrester is when casthouse equipment needs maintenance, first the bolt 8 that transition conduit couples with gas skirt, ventilation duct is removed, then with the first electric block transition conduit 2 dismantled and remove, finally with 1 gas skirt 4 of electric block with bearing pin 9 for fulcrum upset.
What in figure, label 5 referred to is blast-furnace body.
Knowable to the structure and principle of this utility model dust hood for blast furnace tap hole, this utility model simple in construction, take up space little, save substantial amounts of engineering cost, workman's maintenance industry is time saving and energy saving, easy to operate.After using such structure, this utility model dust hood for blast furnace tap hole its advantageous effect compared with existing dust excluding hood is as follows::
