Description
Technical field
The present invention relates to a kind of environmental improvement device for blast furnace in metallurgical industry cast house tapping hole, specifically refer to a kind of blast furnace iron notch slidingtype extractor fan.
Background technology
Since 20 century 70s, blast furnace keeps the large-scale development, and the production operation of cast house there occurs fundamental change, and along with the prolongation of tapping duration, the smoke contamination time also extends, and the fume amount distributed is big, and soot dust granule is thin, wide to surrounding environment influence scope.If do not taked effective control measure, the most not only pollute environment, and will seriously hinder operation and the safety of cast house, simultaneously for equipment, instrument properly functioning, also will be to threaten greatly.Blast furnace discharge yard flue dust mainly produces from positions such as tapping hole, slag skimmer, roughing runner, trough and swing spouts.During blast furnace casting, cast house almost has half area to give out flue dust to some extent, produces radiant heat.In latter stage of tapping a blast furnace, tapping hole also sprays the flue gas containing CO, not only severe contamination environment around, and directly affects the operation of workman and healthy.It is thus desirable to blast furnace iron notch to be carried out the anti-pollution improvement of emphasis.
The most domestic administering method to blast furnace discharge yard tapping hole dust mainly arranges a fixed draught hood on tapping hole top platform, blast furnace casting water when, tapping hole is carried out ventilation and dust removal.The subject matter that this administration way exists is as follows:
1) air draft pipe of fixed draught hood arranges support of duct in blast furnace casting Ground difficulty, and support of duct basis is difficult to adapt with cast house practical situation.
2)
Fixed draught hood position is fixed, and is positioned at directly over tapping hole, and cover body the most at high temperature toasts, and easily causes cover body deformation and breakage.
3) when of carrying out excavation in main runner and repair ditch, fixing draught hood position is fixed, and hinders the normal work of the car lifting of purlin, stokehold and excavator.
4) fixed draught hood due to support of duct be unfavorable for arrange, so general fixed draught hood profile is less, cover open area is little, little to dust catching scope, causes flue dust to fill the air, and arresting efficiency is low.
Be badly in need of at present wanting one to facilitate stokehold to construct in sum, can be along rail linearity reciprocating；Being controlled by flushing and casting human users's case, control mode is simple, maintenance workload is little, failure rate is low；Suction opeing is not susceptible to the blast furnace iron notch slidingtype extractor fan of feed blocking.
Summary of the invention
The technical problem to be solved in the present invention be to provide one facilitate stokehold construction, can be along rail linearity reciprocating；Being controlled by flushing and casting human users's case, control mode is simple, maintenance workload is little, failure rate is low；Suction opeing is not susceptible to the blast furnace iron notch slidingtype extractor fan of feed blocking.
For solving above-mentioned technical problem, the technical scheme that the present invention provides is: a kind of blast furnace iron notch slidingtype extractor fan, it includes rectangular beam exhaust column, slidingtype air exhauster, steel wire rope, actuating unit, clamping device, pulley and track；The bottom of described rectangular beam exhaust column is provided with track, and the top of described slidingtype air exhauster is provided with pulley；Described pulley rolls with track and coordinates；The bottom of described rectangular beam exhaust column is also equipped with actuating unit, and actuating unit is provided with one can be around the reciprocating steel wire rope of actuating unit；Described steel wire rope is connected with slidingtype air exhauster；It is also equipped with on described actuating unit for making steel wire rope keep the clamping device of expanding force.
As preferably, the air draft passage between described rectangular beam exhaust column and slidingtype air exhauster is to be provided with gap between ring flange docking structure and two abutted flange dishes.
As preferably, described actuating unit be one group by motor-driven roller.
As improvement, in described rectangular beam exhaust column, set deflector.
Use after said structure, present invention have the advantage that 1, the present invention works operation characteristic according to blast furnace discharge yard, using rectangular beam the exhaust column not only supporting construction as blast furnace iron notch slidingtype extractor fan but also the air draft pipe as slidingtype extractor fan.
2, the present invention periodically repaiies the feature of ditch according to blast furnace discharge yard, and slidingtype extractor fan is designed to linear reciprocating mobile device.The when of blast furnace casting water, slidingtype extractor fan is positioned at directly over tapping hole and in time tapping hole is carried out ventilation and dust removal；The when that ditch being repaiied by blast furnace, slidingtype extractor fan can be moved to spacious side, not affect and repair ditch operation by electric transmission machanism by slidingtype extractor fan；Not during molten iron discharging, by actuating device, slidingtype extractor fan can be removed directly over tapping hole and carry out cover body surface iron filings and clear up, thus effectively prevent cover body deformation and damaged, extend slidingtype extractor fan service life.
3, slidingtype extractor fan of the present invention passes through actuating device horizontal reciprocating movement in orbit, relatively low to power demand, uses field operation box manual operation, controls the comparatively simple facility of program.
4, due to the fact that and between rectangular beam exhaust column with slidingtype extractor fan, use flange plate type to dock, effectively prevent high temperature from causing the deformation dislocation of cover body interface, reduce wild wind suction.
In sum, the invention provides one facilitate stokehold construction, can be along rail linearity reciprocating；Being controlled by flushing and casting human users's case, control mode is simple, maintenance workload is little, failure rate is low；Suction opeing is not susceptible to the blast furnace iron notch slidingtype extractor fan of feed blocking.
