Description
Technical field
The utility model is related to ironmaking technology field more particularly to a kind of blast furnace taphole Environmental-protecting dust-removing operating rooms.
Background technology
Flue dust short time eruption amount in blast furnace discharge yard iron mouth region domain is big, jet power is strong, temperature is high, in hot pressing and the work of furnace pressure
It is spouting from iron hook and spread rapidly under, entire cast house is spread in, causes serious environmental pollution.Traditional settling mode
It is to be disposed about removable top draft hood and side-draught hood in Tie Kou, without masking, equipment is simple in iron mouth region domain.
The iron mouth of blast furnace is normally at the higher position of blast furnace, setting tuyere platform in top on the outside of iron mouth, during practical operation
Can cast house platform be set in contour position, be inhaled for placing the machine of blocking up and trough opened, prior art and equipment using top
Cover and side-draught hood negative pressure exhausting, cover body is near from iron mouth, influences iron jaws equipment and opens the operation and maintenance of the machine of blocking up, and seriously affects iron
Ditch tap drain and the repair of iron mouth need first to remove cover body or set removable dust excluding hood.But bad environments herein,
Fume amount is big, temperature is high, and dust excluding hood is easily deformed, and moving equipment failure rate is high, and present enterprise has mostly cancelled mobile cover body.
Due to repair and maintenance and severe stokehold hot environment, blast furnace taphole region is also not provided with the hazard prevention for preventing iron mouth from spraying greatly
Facility.
Iron mouth high-pressure injection formula flue dust can not be trapped all, and factory roof need to set final dusting, not met now stringent
Environmental requirement, and cause roof structure complicated.
Utility model content
Purpose of utility model：The purpose of this utility model, which is to provide, a kind of to be completely enclosed blast furnace taphole and trough neither
Influence the blast furnace taphole Environmental-protecting dust-removing operating room that flue dust zero-emission is realized in flushing and casting again.
Technical solution：The blast furnace taphole Environmental-protecting dust-removing operating room of the utility model, the iron mouth outside top of the blast furnace are set
There is a tuyere platform, be equipped with that trough is connected, and the trough end is equipped with operculum colpi at iron mouth, the trough is arranged on
It is disposed on cast house platform, on cast house platform and opens the machine of blocking up, for flushing and casting, one end of the cavity operating room and operculum colpi
Splicing, the taphole frame of the other end and iron mouth are welded, are open below, and edge of opening is used with cast house platform surface detachably to be connected
It connects, iron mouth is made to be formed about a closed cavity, the cavity operating room is additionally provided with dust-extraction unit so that iron mouth opens moment spray
Flue dust out is flowed in operating room, then is excluded by dust-extraction unit, it is possible to prevente effectively from the unordered discharge of flue dust, pollutes.
Further, the operation console and the inside that the machine of blocking up is located at cavity operating room is opened, then can directly operate
In-house operation opens the machine of blocking up and other equipment.
Further, the dust-extraction unit includes the depression dust-removing pipe for being arranged on cavity operating room upper outside, which removes
It is connected inside dirt pipe and cavity operating room.
Wherein, the cavity operating room includes pre-set detachable frame and is spliced into closing with detachable frame
The detachable hanging plate of cavity body structure is repaiied in stokehold and during overhaul, there is no removing top to inhale and the problem of side absorbs dust hood, removes extension
Plate can also remove frame as needed.
It, can be directly in its correspondence since the inner wall and top plate of the cavity operating room increase the distance with molten iron level
Surface sets one layer of ceramic beaverboard, and proportion only has 1/the tens of fire-proof spray coating, solve stokehold largely spray it is heat-insulated
The problem of material installation quality is big, maintenance workload is big.
Advantageous effect：Compared with prior art, it is the advantages of the utility model：(1) first, the suction of iron mouth top and side are eliminated
Dust hood is absorbed, reduces the maintenance that stokehold moves top draft hood；(2) secondly, stokehold space for maintenance and dust removal requirement are solved
Contradiction, can carry out iron mouth area equipment at any time and tap drain is safeguarded；(3) again and, do not use heavy refractory material, reduce resistance to material into
Sheet and maintenance work；(4) finally, it has effected a radical cure stokehold to tap a blast furnace the Heavy environmental pollution problem of field areas, has realized flue dust zero-emission, solution
Iron mouth of having determined sprays greatly the danger of generation.
Description of the drawings
Fig. 1 is the utility model apparatus structure schematic diagram.
Specific embodiment
The technical solution of utility model is described further below in conjunction with the accompanying drawings.
Blast furnace taphole Environmental-protecting dust-removing operating room as shown in Figure 1, the 1 outside top of iron mouth of the blast furnace are equipped with tuyere platform
2,2 lower section of tuyere platform, which is equipped with, seals hanging plate, and connected equipped with trough 3 at iron mouth 1,3 end of trough is equipped with
