[technical field]
The utility model relates to the blast-furnace tuyere technical field, specifically, is a kind of device of clearing up slag tuyere iron.
[background technology]
Blast-furnace tuyere, the important channel as observing situation in the stove is in very consequence when blast furnace operating.When blast furnace staying etc. in particular cases, may cause the generation of slag tuyere situation, cause and to observe situation in the stove by the air port, in existing situation, generally be to dredge by the mode that adopts direct burning oxygen cleaning, clearance time is longer, the cleaning difficulty is larger, punching is unclean, and the easy scaling loss of tuyere small sleeve affects blast furnace and normally produces behind the furnace compound wind.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of device of clearing up slag tuyere iron is provided; Can rapidly slag spades in the air port be removed totally, reduce and adopt at present the directly danger of burning oxygen cleaning operation.
The purpose of this utility model is achieved through the following technical solutions:
A kind of device of clearing up slag tuyere iron, described device is arranged on the air port of blast furnace, it is characterized in that, comprise handle, parking brake, head, stay cord connecting rod and screw mandrel puopulsion unit, handle is by pin or be bolted to stay cord connecting rod one end, and parking brake is by pin or be bolted to lower end near the stay cord connecting rod of handle end, the other end of the stay cord connecting rod that head is arranged on; The screw mandrel puopulsion unit links to each other with handle with the handle rifled tube by wire rod thread; The inside of head is provided with fills with slag iron storage tank.
The number of described bearing is two, by pin or be bolted near on the stay cord connecting rod of parking brake.
Described oxygen blowpipe passes two bearings, after passing first tracheae bearing, and then passes a jump ring and links to each other with second bearing.
Described head design is semicircle basis groove scoop structure, its head inside is provided with fills with slag iron storage tank, its curvature is advisable with the air port inwall of can fitting, shovel shape head stretches into the air port, applying air port inwall advances, and gos deep into slag iron to be rooted out smoothly and being accumulated in the process of inside, air port in the shovel shape head groove.
Compared with prior art, positively effect of the present utility model is:
When the blast-furnace tuyere dross occuring or fill with the slag situation, but adopt this device one man operation, rapidly slag spades in the air port is removed clean, reduce and adopt at present the danger of directly burning the oxygen cleaning operation, this apparatus structure is simple simultaneously, can carry out fast part replacement, strengthens its scope of application.

[embodiment]
Below provide the utility model a kind of embodiment of clearing up the device of slag tuyere iron.
Embodiment 1
See also accompanying drawing 1-5, a kind of device of clearing up slag tuyere iron, described device is arranged on the air port of blast furnace, it is characterized in that, comprises handle 1, parking brake 2, head 3, stay cord connecting rod 6 and screw mandrel puopulsion unit 12, handle is by pin or be bolted to stay cord connecting rod 6 one ends, parking brake 2 is by pin or be bolted to lower end near the stay cord connecting rod 6 of handle end, the other end of the stay cord connecting rod that head 3 is arranged on; Screw mandrel puopulsion unit 12 links to each other with handle with handle rifled tube 15 by wire rod thread 14; The inside of head is provided with fills with slag iron storage tank 4.
Bearing 9 is by pin or be bolted near on the stay cord connecting rod 6 of parking brake, and the number of described bearing 9 is two.
Described oxygen blowpipe 10 passes two bearings, after passing first tracheae bearing, can pass a jump ring 11 and link to each other with second bearing.
Described head design is semicircle basis groove scoop structure 5, its head inside is provided with fills with slag iron storage tank 4, its curvature is advisable with the air port inwall of can fitting, shovel shape head stretches into the air port, applying air port inwall advances, and gos deep into slag iron to be rooted out smoothly and being accumulated in the process of inside, air port in the shovel shape head groove.
Described screw mandrel puopulsion unit 12 is linked to each other with handle with handle rifled tube 15 by wire rod thread 14.
In when, the air port dross occuring or fill with slag iron situation when, oxygen blowpipe 10 is passed two tracheae bearings 9, after passing first tracheae bearing, can pass a jump ring 11, when oxygen blowpipe 10 is placed as shown in Figure 3, adjust jump ring 11 positions, can't break away from front end tracheae bearing during with oxygen blowpipe 10 post-tensioning and be advisable; Hand-held this device handle 1 stretches into the air port with its head 3, parking brake 2 keeps the relieving states at this moment, shovel shape head 3 straight applying air port inwalls slowly push, run into slag iron in the air port in the push-on process, keep cleaning plant stable, adjust the depth of penetration of oxygen blowpipe 10, slag iron is heated, cleaning plant is applied certain power push inward, the slag iron of soft heat will be scooped up and be entered in the groove of shovel shape head 3.
Many such as slag iron amount in the air port, slag iron is deposited too much in shovel shape head 3 grooves, the difficulty of slag iron cleaning is proceeded in impact, then when the holding device monolithic stability, oxygen blowpipe 10 is drawn back, compress parking brake 2, stay cord 6 driven rotary axles 8 rotate, torsion spring 7 tightens up, and shovel shape head 3 is upturned, and the slag iron on it will be constructed 5 landings to the slag iron storage tank 4 at rear portion along ramped shaped, unclamp parking brake 2, torsion spring 7 is replied, and shovel shape head 3 recovers straightened condition, can proceed that the slag spades removes operation in the air port in.Thawing causes shovel shape head 3 to stick on the inwall of air port such as pomace iron, rely on parking brake 2 will shovel the perk of shape head, then stablize on the other hand handle and parking brake, rotary screw puopulsion unit 12, push away in the screw mandrel, cooperate 13 pairs of shovels of the webge slot shape head 3 under the shovel shape head 3 to produce larger upward force effect, will shovel the perk of shape head.
After rooting out totally, retreat oxygen blowpipe 10, compress parking brake 2, will shovel 3 perks of shape head, slowly pulling off device prevents that slag iron is lost in the air port.
This device can remove slag spades in the air port rapidly clean, and this apparatus structure is simple simultaneously, can carry out fast part replacement, is equipped with the component of different size, can strengthen its scope of application, extends to eliminating impurities field in the pipeline, and cleaning effect is obvious.
