Description

Mud gun nozzle tip extraction device {Apparatus for disassembling mud gun nozzle tip}

The present invention relates to a mud gun nozzle tip extraction device, and more particularly, to a mud gun nozzle tip extraction device capable of easily taking out a nozzle tip by gripping a nozzle tip provided at an end of a mud gun.

Ordinary outlets are devices made of refractories and passed through open air to discharge molten iron and slag out of the blast furnace.

MUD GUN is used as a device that closes the outlet by turning the mud gun filled with mud material when a hollow phenomenon occurs in the outlet after a certain amount of time has elapsed.

The mud gun nozzle tip (MUD GUN NOZZLE TIP) should be in a circular shape to eliminate the cause of leakage or failure of closing when the outlet is closed.

Conventionally, in order to maintain the original shape of the mud gun nozzle tip, a worker manually replaces the tip.

However, when a worker works for a long time, continuous work is difficult due to exhaustion of physical strength due to high heat and gas, and there is a problem that becomes a risk factor for safety accidents due to heavy handling.

In particular, since the loss of the tip of the mud gun due to the failure of the closing of the outlet requires urgency, the replacement of the nozzle tip should be carried out early, but as described above, manual work increases the replacement time, resulting in loss of productivity in the furnace. there is a problem.

Accordingly, in recent years, the development of a technology for facilitating the replacement of the mud gun nozzle tip is required.

A plurality of fixing parts 200 according to the present invention are arranged at equal intervals at multiple positions around the body part 100 .

The plurality of fixing parts 200 are rotated in a link manner and are caught and fixed by the stepped part 31 between the nozzle body 20 and the nozzle tip 30.

The configuration of the plurality of fixing parts 200 will be described.

Each of the plurality of fixing parts 200 is composed of a fixing member 210 and a holding member 220 .

The fixing member 210 is formed to protrude from the circumference of the body 100 along one side. That is, the fixing member 210 protrudes along a direction perpendicular to the body portion 100 .

Support members 120 protruding along the radial direction are formed at multiple positions around the body 100 .

One end of the fixing member 210 is fixed to each of the support members 120 .

Auxiliary support members 121 protrude from each of the support members 120 , and the auxiliary support members 121 are connected to one end of the fixing member 210 . Accordingly, each of the fixing members 210 may be fixed through additional fixing force in the corresponding support member 120 by the auxiliary support members 121 .

A hinge end 211 is formed at the other end of the fixing member 210 .

One end of the locking member 220 is rotatably connected to the hinge end 211 .

A hooking end 221 that is bent is formed at the other end of the hooking member 220 .

Depending on its configuration, each of the fixing parts 200 may form a structure capable of rotating at multiple positions around the body part 100 .

In addition, the body portion 100 includes a fixed chain 130 having a grip member (not shown) at one end.

The other end of the fixing chain 130 is fixed at a predetermined position around the body 100 .

In addition, a seal member 110 inserted into the opening is formed in the inner central portion of the body portion 100 according to the present invention so as to be in close contact with the inner circumference of the opening.

5 is a cross-sectional view showing another example of a body part according to the present invention.

As shown in FIG. 5 , the seal member 110 is made of metal having heat resistance. Also, the seal member 110 may protrude in multiple stages to form different diameters.

6 is a view showing a state in which the nozzle tip extraction device of the mud gun according to the present invention is mounted on the nozzle tip.

1 to 6, the process of installing the nozzle tip extractor of the mud gun according to the present invention to the nozzle tip will be described.

A plurality of fixing parts 200 form a state in which the outer circumference of the body part 100 is spread out at a number of positions.

The body part 100 may seal the opening of the nozzle tip 30 disposed at the end of the nozzle body 20 of the mud gun.

At this time, the seal member 110 formed on one side of the body 100 enters the opening of the nozzle tip 30 . At the same time, the outer circumference of the seal member 110 may be in close contact with the inner circumference of the opening of the nozzle tip 30, and one side of the body 100 may be in close contact with the outer surface near the opening of the nozzle tip 30.

In addition, the plurality of fixing parts 200 that are open and waiting may be caught and fixed to the stepped part 31 formed between the nozzle tip 30 and the nozzle body 20.

That is, the locking member 220 of each fixing part 200 is rotated with the hinge end 211 as the center of rotation, and the locking end 221 formed at the other end of the locking member 220 is the stepped portion 31 ) and is fixed.

In the process of being caught by the stepped part 31 formed between the nozzle tip 30 and the nozzle body 20 at different positions, the holding member 220 of each fixing part 200, the body part 100 is attached to the nozzle tip (30) side can be pressed.

Accordingly, the body part 100 according to the present invention can grip the nozzle tip 30 with a certain force.

In addition, by using a grip member provided at an end of the fixed chain connected to the body, it can be caught on the stepped portion formed between the nozzle tip and the nozzle body.

Since the fixing chain connects the body part and the stepped part, even if some of the fixing parts are loosened, the problem caused by the body part falling to the floor can be solved.

Through the above configuration and action, the nozzle tip can be easily removed by gripping the nozzle tip provided at the end of the mud gun.

In addition, the present invention prevents the nozzle tip from being ejected to the outside due to the high-temperature and high-pressure mud material by additionally fixing the nozzle tip to the nozzle body using a chain while holding the nozzle tip, and prevents the mud material from being ejected to the outside. can

In addition, according to the present invention, as the seal member is inserted into the nozzle tip, it is possible to induce the nozzle tip to be separated regardless of the dissolution loss of the nozzle tip and to prevent the hot mud material from being ejected to the outside.

In addition, by connecting and fixing to the nozzle body using a fixed chain, it is possible to easily prevent the device from protruding outward during the process of separating the nozzle tip.

In addition, the plurality of fixing parts of the present invention can be easily mounted on the nozzle tip by forming a link structure using a hinge end.

Meanwhile, hinge holes 212 are formed at different positions in the fixing member 210 according to the present invention.

The hinge end 211 may be selectively installed in any one of the hinge holes 212 .

Through this, it is possible to variably select the protruding position of the fixed member 210 that is rotated, so that it can be easily applied to other nozzle tips having different positions of the stepped part 31 .

In particular, a central hole 101 is formed at the center of the body portion 100 . A space is formed inside the sealing member. The space is exposed to the central hole 101 .

In addition, the body portion 100 protrudes to form multiple stages along the outside so that the diameter gradually decreases. Through this, it has an advantage of being able to seal nozzle tips having various inner diameters.
