Description

Coupling device for coal oxygen pipe belt

Technical Field

The utility model belongs to the technical field of metallurgical equipment maintenance technique and specifically relates to a coupling device for coal oxygen pipe area.

Background

After the molten steel is smelted, in order to ensure the quality of the steel billet, the surface defects of the steel billet need to be burnt out by the gas cutting and melting-removing action of high-temperature flame. The domestic flame cleaning is mainly divided into mechanical cleaning and manual cleaning, and the manual cleaning is mainly used in places where the site is narrow and large-scale machinery cannot be used.

When the blast furnace gas is manually cleaned, the blast furnace gas is used as a gas source of high-temperature flame, and the blast furnace gas is conveyed by a coal oxygen tube belt. The blast furnace gas contains fine particles, the edges and corners of the particles are sharp, the coal oxygen tube belt is damaged after being used for a period of time along with the continuous conveying of the high-pressure gas in the coal oxygen tube belt and the collision with the inner wall of the coal oxygen tube belt, and the cost for replacing the tube belt in a whole roll is high; in the process of cleaning the surface of the billet, the coal oxygen pipe belt inevitably contacts the billet due to the working environment, and the high temperature of the billet easily causes the coal oxygen pipe belt to break. Once the coal oxygen pipe belt is damaged, coal gas and oxygen can be leaked into the air, and a large potential safety hazard can exist due to the fact that the temperature of the field environment is high. In order to solve the problem of the rupture of the coal oxygen pipe belt, the industry generally attaches adhesive tapes to the damaged part of the coal oxygen pipe belt for repairing in view of cost reduction, but the actual effect is not ideal.

FIG. 2 is a cross-sectional view taken along line A-A of FIG. 1;

labeled as: 100-coal oxygen tube belt, 200-sealing layer, 210-flexible surface layer, 220-fiber wire, 300-bolt, 400-protective layer and 500-lacing tape.

Detailed Description

In order to facilitate understanding of the present invention, the following description is further provided with reference to the accompanying drawings.

The connecting device for the coal oxygen pipe belt is used for plugging the damaged part of the coal oxygen pipe belt 100 and sealing the joint part of the coal oxygen pipe belt 100; as shown in fig. 1 and 2, the sealing layer 200 wraps the coal oxygen pipe strip 100 and then is connected end to end by fasteners. Because coal oxygen pipe area 100 is the hose, can not adopt conventional fastening mode directly to fix sealing layer 200 on coal oxygen pipe area 100, otherwise can let coal oxygen pipe area 100 warp because of the extrusion, the utility model discloses in adopt bolt 300 as the fastener, can directly utilize bolt 300 to press from both sides the head and the afterbody of sealing layer 200 tightly, also can set up corresponding hole on the head of sealing layer 200 and afterbody, pass bolt 300 behind the hole with supporting nut connection fastening.

The utility model discloses well sealing layer 200 adopts three layer construction, as shown in FIG. 2, sealing layer 200 comprises flexible top layer 210 and cellosilk 220, and flexible top layer 210 is as the internal surface layer and the extexine of sealing layer 200, and cellosilk 220 is filled between inside and outside two-layer flexible top layer 210. Because the coal oxygen tube belt 100 has elasticity, the sealing layer 200 is made of elastic material, and the flexible surface layer 210 and the fiber filaments 220 are made of materials with certain strength and elasticity, so that the coal oxygen tube belt can be better attached to the surface of the coal oxygen tube belt 100, and a better sealing effect is provided; the fiber filaments 220 can increase the scouring resistance and the yielding resistance of the sealing layer 200, have better abrasion resistance to fine particles mixed in blast furnace gas, and can effectively prolong the service life of the sealing layer 200. From the perspective of cost savings, flexible skin 210 may be prepared using waste conveyor belts from commercial production.

Because the field work environment is comparatively abominable, in order to avoid coupling device and high temperature steel billet to collide and wear, the utility model discloses in still set up inoxidizing coating 400 in the outside of sealing layer 200, inoxidizing coating 400 wraps up sealing layer 200, and inoxidizing coating 400 can adopt the preparation of steel material, can play effectual guard action to sealing layer 200.

Although the head and the tail of sealing layer 200 have been connected through the fastener, but gas leakage easily takes place at the both ends position of sealing layer 200, consequently the utility model discloses set up lacing tape 500 at the both ends of sealing layer 200 and seal, as shown in fig. 1, can set up the turn-up at the both ends of sealing layer 200, lacing tape 500 passes from the turn-up, can be with lacing tape 200's both ends head lacing tape coal oxygen pipe 100 with lacing tape 500's head and the tail chucking on, provide better sealed effect.
