Abstract
The utility model relates to a closed cover for trapping dust sources in an iron notch of a blast furnace cast house, and comprises an exhaust tube and a cover body 3. The utility model is characterized in that the exhaust tube is transversely arranged above the iron notch and is a telescopic tube, the exhaust tube comprises an outer tube 1 and an inner tube 2, the outer tube 1 is fixed on a track beam 8, one end of the inner tube 2 is sheathed in the outer tube 1 and the other end is connected with the cover body 3, and a guide wheel 4 which is arranged on the lower portion of the inner tube 2 is mounted on the track beam 8. The utility model solves the problem of the multi-point random moving exhaust, and can randomly point-exhaust within the range of a walking track of the track beam 8. The longitudinal space occupied by the trapping equipment is reduced, the air leakage loss is reduced, and the trapping rate of dust sources airflows is high.
Description
Technical field
The utility model belongs to trapping technique field, dirt source, is specifically related to a kind of enclosed hood that blast furnace discharge yard iron notch dirt source captures that is used for.
Background technology
The blast furnace discharge yard iron notch is paroxysmal dirt source, and dust-producing amount is big, pollutes very serious.The iron notch dirt source catching apparatus of blast furnace discharge yard dust-removal system is a dust excluding hood at present, and dedusting is covered with and fixedly takes out dust hood and the mobile dust hood of taking out.Fixedly take out dust hood and be arranged on the iron notch top, cover and induced exhaust all are fixed, and this technical scheme is only applicable to a blast furnace iron notch or iron notch does not have the Working environment that other production unit influences.The mobile dust hood of taking out can solve the problem that the shared cover of two or more iron notchs is taken out dust hood.The existing structure formation of taking out dust hood that moves: induced exhaust vertically is set respectively above each iron notch, and cover is removable, and when certain iron notch tapped a blast furnace, cover just extracted the dirt source with corresponding induced exhaust butt joint.Because numerous blast furnace discharge yard production technique and technical parameter requirement, this defective of taking out dust hood that moves has: 1, when cover moves butt joint, owing to the slit that has between induced exhaust and the cover about 300mm, air leak rate of air curtain is big, generally more than 15%; 2, the dirt source captures narrow range, working condition requirement in particular cases such as can not realize that multipoint random moves exhausting and satisfies that closely two iron notchs take turns to operate; 3, the hold facility longitudinal space is big, influences the work of other production units.The CN2719855Y patent disclosure a kind of blast furnace iron notch hinged top absorb the dirt device, this device dust excluding hood is a sloped top face, and be hinged on the outer ledge of tuyere platform, cover body can swing up and down around pin joint, this device also exists dirt source collection face narrow, can not realize the multiple spot defective of exhausting immediately.
Summary of the invention
The purpose of this utility model provides a kind of telescopic closing cover for mobile vehicle, solves air-flow capture of blast furnace iron notch dirt source and catching apparatus and arranges difficult problem.
Technical solution of the present utility model is: telescopic closing cover for mobile vehicle, comprise induced exhaust and cover body, induced exhaust places iron notch top lateral arrangement, induced exhaust is the telescopic tube form, form by outer tube and interior pipe, between outer tube and the interior pipe 5～15 millimeters slit is arranged, sealing member is set in the slit, sealing member is a steel bar, has 2～10 slotted eyes on the steel bar.Outer tube is fixed on the track girder, and interior Guan Yiduan is inserted in outer tube, and the other end connects cover body, makes enclosed hood become inverted "L" shaped.In the pipe bottom guide wheel is set, guide wheel is installed on the track girder, pipe becomes the dolly that can move with guide wheel in making, moving by driving member of interior pipe drives, driving member can be windlass, pipe in windlass connects by transmission conductor rope rope, and pipe moves arbitrarily on track girder in driving.
The beneficial effects of the utility model are as follows:
1, the mode that has adopted dust hood to be connected with the dolly main part of telescopic type induced exhaust, solved the problem that multipoint random moves exhausting, not only can be in track girder be walked the scope of track the arbitrfary point exhausting, also because the induced exhaust lateral arrangement has reduced the longitudinal space that catching apparatus takies.
2, utilize telescopic tube as induced exhaust, and be provided with adjustable sealing member, reduced the loss of leaking out, saved running cost, dirt source air-flow capture rate height has reduced the dust pollution of operation field.
3, telescopic closing cover for mobile vehicle is established fixed dolly moving track, and the windlass transmission has guaranteed travelling car operation reliably steady in a long-term.

Embodiment
The telescopic closing cover for mobile vehicle that employing the utility model proposes, the applicant implements at the iron notch of the iron work 5# of Chongqing iron and steel group company blast furnace.Heavy steel iron work 5# blast furnace has been arranged two iron notchs in the position of 3 meters of adjacent 30 ° of angle spacings, each oral-lateral that taps a blast furnace has respectively disposed a cover clay gun and a taphole drilling machine, be subjected to the influence of production technique and site condition, can't arrange and fixedly take out dust hood and the general mobile dust hood of taking out.
The utility model places iron notch top lateral arrangement with induced exhaust, induced exhaust is a telescopic tube, form by outer tube 1 and interior pipe 2, outer tube 1 is fixed on the track girder 8, interior pipe 2 one ends are inserted in outer tube 1, and the other end connects cover body 3, and interior pipe 2 bottoms are provided with guide wheel 4, guide wheel 4 is installed on the track girder 8, makes cover body 3 and interior pipe 2 integral body become travelling car.In pipe 2 is connected with driving member, driving member is a windlass 7, windlass 7 manages 2 by 6 connections of transmission conductor rope rope are interior.The slit that 10 millimeter are arranged between the outer tube 1 of induced exhaust and interior pipe 2, for preventing to leak out, sealing member 5 is set in the slit, sealing member 5 is steel bar structures, for making sealing tight, have on the steel bar 2～10 slotted eyes be used to adjust in stopping property between pipe 2 and the outer tube 1, after adjust the slotted eye position of sealing member 5, with rubber plate, steel clamping plate, iron bottom plate and bolt, nut, packing ring fixing seal.
The application of the utility model in heavy steel 5# blast furnace discharge yard dust-removal system, efficiently solve because production unit influence can't be arranged and fixedly take out the problem that dust hood and multiple spot are at random taken out dirt, significantly reduced of the pollution of heavy steel blast furnace discharge yard flue gas, improved site work environment environment.
