The gun head needs to be replaced by slow wind, the influence on safety and environment is large, the workload is large, and the working efficiency is low.

The invention discloses a CN201911208614.8 blocking device for preventing dust overflow of a blast furnace taphole, relates to a blocking device for preventing dust overflow of a blast furnace taphole, and belongs to the technical field of environment-friendly dust removal equipment of blast furnace slag iron discharge systems in the metallurgical industry. The technical scheme is as follows: the steel structure integral framework is arranged around the taphole and fixed on the platform in front of the furnace, the plugging top plate is fixed at the top of the steel structure integral framework, the plugging side plates are respectively fixed on two sides of the steel structure integral framework, the plugging slag trap is fixed on the front of the steel structure integral framework, the plugging top plate, the plugging slag trap, the plugging side plates, the blast furnace body, the tuyere platform, the taphole top suction hood, the taphole cover plate and the platform in front of the furnace form a taphole area closed space, smoke dust in the taphole area can be completely sealed without overflowing, and the smoke dust is discharged through the taphole top suction inlet and the side suction inlet to enter a pipe network for purification.

The utility model discloses a CN201921571498.1 blast furnace emergency iron notch blocking device, relating to the technical field of metallurgical production equipment, comprising a gun barrel arranged on a girder of an iron notch drill, wherein the front end of the gun barrel is provided with a gun head with an opening at the middle part, a push rod is movably arranged in the gun barrel in a penetrating way, the front end of the push rod is provided with a mud pressing block connected with the gun barrel in a sliding way, and the rear end of the push rod extends out of the gun barrel and is connected with a drilling mechanism of the iron notch drill; and water stemming is arranged between the stemming head and the stemming pressing block. And pushing the push rod and the mud pressing block to move forwards from back by adopting a drilling mechanism of the taphole drilling machine, and pushing the water stemming in the gun barrel out of the gun head to plug the taphole.

The mud leakage phenomenon of the mud gun head occurs when tapping and blocking are carried out in front of the furnace, the gun head needs to be replaced by slow wind, the influence on safety and environment is large, the workload is large, and the working efficiency is low. The iron notch plugging equipment which is convenient to disassemble and assemble is not available.

Disclosure of Invention

The iron notch plugging device is convenient to disassemble and assemble, and iron notch plugging is enhanced during production.

In order to solve the technical problem, the utility model provides a following technical scheme a convenient dismouting tinplate notch shutoff equipment, it includes, sets up the horn mouth outside the mud gun barrel, is equipped with the big gun head of big gun mouth, and set up in the anterior big gun cap of big gun head.

Preferably, the gun cap is conical.

Preferably, the taper of the gun cap is 29.5 degrees.

Preferably, the gun head is movably connected with the gun cap.

Preferably, the gun head is positioned at the front part of the mud gun and is used for blocking and mud-beating the taphole.

Preferably, the gun body of the clay gun is connected with the gun head through a pin.

The utility model has the advantages that:

the utility model provides a convenient dismouting tinplate notch shutoff equipment increases a movable gun cap before former big gun head, makes mud big gun and the seamless butt joint of tinplate notch, reaches effectual airtight sprue of playing, the effect that prevents the tinplate notch and run mud when the sprue to improve site environment, alleviate workman's work load.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Description of the reference numerals

The gun comprises a bell mouth 1, a gun nozzle 2, a pin 3, a gun cap 4, a gun head 5 and a gun body 6.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanying the present invention are described in detail below with reference to the accompanying drawings.

Example 1

As shown in fig. 1, the utility model provides a pair of convenient dismouting tinplate notch shutoff equipment relies on and carries out the shutoff to the tinplate notch on mud big gun's basis.

The utility model discloses have the horn mouth 1 that sets up outside the mud gun big gun body, be convenient for hold the anterior uplift position of dress mud gun, do benefit to the high registrate of convenient dismouting tinplate notch shutoff equipment and mud gun. At the mud big gun front portion, the big gun head 5 that is equipped with big gun nozzle 2 is used for the indisputable mouthful shutoff to beat mud, sets up in the anterior big gun cap 4 of big gun head 5 can effectual airtight stifled mouthful, plays the effect that prevents the indisputable mouthful and run mud. In order to facilitate the disassembly and replacement, the gun head 5 and the gun cap 4 are movably connected, such as threaded connection, pins, chains and the like. Considering the convenience of operation, less accessories are used, and the gun head 5 and the gun cap 4 are preferably connected through a bayonet and can be clamped, and the locking and the anti-loosening are realized.

Further, the gun cap 4 is in a conical shape, a trapezoid shape or a truncated cone shape, the shapes of the gun cap 4 are provided with a relatively sharp end, and after the gun cap 4 is sleeved into the gun head 5, the relatively sharp end can tightly seal the iron notch to prevent the iron notch from mud leakage. In the production practice, through experimental summary many times, discover when gun cap 4 and big gun head tapering are 29.5 degrees, guarantee shutoff effect that can be fine, in addition, because big gun cap 4 is through bayonet connection with big gun head 5, when dismantling or changing, the tapering of 29.5 degrees has given the sense of grasp of operating personnel preferred, can dismantle the work more laborsavingly.

Furthermore, the gun head and the gun cap of the equipment are positioned in front of the blast furnace, and the gun body 6 of the mud gun is connected with the gun head 5 through the pin 3, so that an integrated manufacturing chain of the blast furnace, the mud gun and the gun match is formed, the field environment is improved, and the workload of workers is reduced.

The utility model provides a convenient dismouting tinplate notch shutoff equipment increases a movable gun cap before former gun head, makes mud gun and the seamless butt joint of tinplate notch, reaches effectual airtight sprue, the effect that prevents the tinplate notch from running mud of playing when the sprue, and this kind of redesign mud gun head, gun cap, toper gun cap plays fine closed effect when going out the iron sprue in the front of the furnace, reaches and does not run mud or a small amount of running mud. Through coupling long-term use, even the later stage does not reach the seal effect and burns out the gun cap, the new design's gun head, also convenient to detach of gun cap structure can quick replacement gun cap, have shortened the repair time of the change gun head because of the gun head burns out greatly.
