Abstract
The invention discloses a permeable brick tail pipe anti-blocking device, which comprises a sleeve. The sleeve is adaptive to the shape of a permeable brick tail pipe; an upper pipe opening of the sleeve is of a sealed structure; the sleeve comprises two sections; the joint part of the two sections is connected with an external ferrule by threads; a horizontal stretcher is fixedly connected on the peripheral surface of the external ferrule or the sleeve; two ends of the horizontal stretcher are respectively provided with a hook; a trigger is hinged with one of the two ends of the horizontal stretcher; and tensioning hooks or tensioning hanging buttons are hinged on the trigger. The permeable brick tail pipe anti-blocking device has the advantages of avoiding a problem that the tail pipe of a permeable brick is blocked during the manufacturing process, ensuring the smoothness of an air guiding channel of the permeable brick, and improving the reliability and the safety; and simultaneously the stability of a core mold of the permeable brick can be improved in the manufacturing process.
Description
Technical field
The present invention relates to be blown into for molten steel in ladle the air brick of argon gas, especially relate to air brick tail pipe anti-block apparatus.
Background technology
Straight-through pass air brick is the field operation instrument that is blown into argon gas by being exclusively used in of making of refractory material in the ladle in the molten steel, to improve degree of purity and the temperature homogeneity of molten steel.Therefore, the unimpeded of the inner air guide channel of straight-through pass air brick is the prerequisite that guarantees its quality.The making of straight-through pass air brick is taked to build moulding in the mould internal vibration and is finished, pug usually takes place in manufacturing process to be spilled in the tail pipe because of carelessness, like this, after super-dry condenses into type, cause airtight or Air permenbility is little, be used for when molten steel is blown into argon gas, causing the degree of purity of molten steel and temperature homogeneity not to reach requiring and discard, even cause molten steel progressively to condense in the ladle automatically, cause ladle to scrap.Simultaneously, in manufacturing process, core influences the quality of brick body in the easy run-off the straight of when vibration, bob phenomenon.
Summary of the invention
The object of the invention is to provide a kind of air brick tail pipe anti-block apparatus, unimpeded with the inner air guide channel of straight-through pass air brick that guarantees to make, and another purpose of the present invention is to improve the stability of straight-through pass air brick core in the manufacturing process.
For achieving the above object, the present invention takes following technical proposals:
Air brick tail pipe anti-block apparatus of the present invention, comprise adapt with air brick tail pipe shape, upper orifice is the sleeve pipe of hermetically-sealed construction; Described sleeve pipe is made up of two joints, and its joining place is connected with outer hoop external threading respectively; Be fixed with the cross-arm frame on hoop cover or the sleeve pipe outer peripheral face outside; Two ends at described cross-arm frame are respectively arranged with hook, and an end therein is hinged with trigger piece, are hinged with the tension hook or strain at described trigger piece to buckle.
Described cross-arm frame is connected in the support ring that downward-sloping on the described outer hoop cover outer peripheral face two cantilever beams and level be connected in described two cantilever beam bottoms by symmetry and constitutes.
The invention has the advantages that and stop air brick blocked problem of tail pipe when making, guarantee that the air brick air guide channel is unimpeded, improve reliability and security that air brick uses; Simultaneously the stability of air brick core is improved.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, air brick tail pipe anti-block apparatus of the present invention, comprise adapt with air brick tail pipe 1 shape, upper orifice is the sleeve pipe 2 of hermetically-sealed construction, described sleeve pipe 2 is made up of two joints, its joining place is threaded with outer hoop cover 3 respectively, be fixed with the cross-arm frame on hoop cover 3 outer peripheral faces outside, described cross-arm frame by symmetry be connected in two downward-sloping on outer hoop cover 3 outer peripheral faces cantilever beams 8,9 and the level support ring 10 that is connected in described two cantilever beams 8,9 bottoms constitute; Two cantilever beams 8,9 bottom are welded with hook 4,5 respectively, also are hinged with trigger piece 6 in the bottom of cantilever beam 8, are hinged with tension hook 7 at described trigger piece 6.
Operation principle summary of the present invention:
When the pass air brick is led directly in making, the suspension ring 12,13 on mould 11 tops are hung on the hook 4,5 of respective cantilevered beam 8,9 bottoms with it, sleeve pipe 2 is sleeved on the air brick tail pipe, and the length of adjusting between outer hoop the cover 3 and two joint sleeve pipes 2 that is spirally connected is carried out the adjusting of sleeve pipe 2 length to satisfy the length requirement of various sizes air brick tail pipe; Then, the suspension ring 12 of tension hook 7 with mould 11 tops are buckled mutually, it is fixing to improve the stability of core rod with mould 11 to pull trigger piece 6 downwards, and making is built in the vibration that can lead directly to the pass air brick.
