Description

Blast furnace belly pipe cooling pipe tool

Technical Field

The utility model belongs to the technical field of iron works blast furnace, concretely relates to blast furnace belly pipe cooling pipe instrument.

Background

The belly pipe is a weak link in a blast furnace air supply system, and the problems of high surface temperature, air leakage, redness, burnthrough, short service life and the like generally exist in the operation of the blast furnace, so that the normal production of the blast furnace is seriously influenced. When the temperature of the front end of the conventional belly pipe is gradually increased, the blast furnace water conservancy project needs to cool by connecting the pressure air pipes, and when the temperature of the front end of the belly pipe is high, the upper temperature and the lower temperature of the front end of the belly pipe are high, the blast furnace water conservancy project needs to connect two pressure air pipes to cool.

Disclosure of Invention

An object of the utility model is to provide a can increase belly pipe front end cooling surface, can save material's blast furnace belly pipe cooling tube instrument again.

The utility model provides a technical scheme that its technical problem adopted is: blast furnace belly pipe cooling tube instrument, including arc tube and oxygen hose, the arc tube transversely installs in the front end of oxygen hose, has seted up a plurality of apertures on the lateral wall of arc tube orientation oxygen hose one side, and the end of oxygen hose is passed through the reducing connecting pipe and is connected with quick-operation joint.

Furthermore, the arc tube, the oxygen tube and the reducing connecting tube are communicated with each other.

Further, the arc of the arc tube faces the oxygen tube.

The utility model discloses following beneficial effect has: the utility model discloses set up the arc pipe at pressure hollow pipe cooling front end, a plurality of apertures are beaten to the inboard, increase belly pipe front end cooling surface, and equipment normal operating is ensured simultaneously to save material.

Drawings

Fig. 1 is a schematic structural view of the cooling pipe tool of the blast furnace belly pipe of the present invention.

In the figure, 1, an arc tube, 2, an oxygen tube, 3, a reducing connecting tube, 4, a quick joint, 5 and a small hole.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings.

As shown in figure 1, the blast furnace belly pipe cooling pipe tool comprises an arc pipe 1 and an oxygen pipe 2, wherein the arc pipe 1 is transversely arranged at the front end of the oxygen pipe 2, the radian of the arc pipe 1 faces to one side of the oxygen pipe 2, and the arc pipe 1 is preferably semicircular. The side wall of the arc-shaped pipe 1 facing the oxygen pipe 2 is provided with a plurality of small holes 5, the number of the small holes 5 is set to be 4-5 according to the requirement, and the tail end of the oxygen pipe 2 is connected with the quick coupling 4 through the reducing connecting pipe 3. The arc tube 1, the oxygen tube 2 and the reducing connecting tube 3 are communicated with each other.

The arc-shaped pipe 1 is semicircular, a plurality of small holes 5 are formed in the arc-shaped pipe, the cooling surface at the front end of the belly pipe is effectively increased, materials are saved, and normal operation of equipment is guaranteed.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention and are not intended to limit the spirit and scope of the present invention. Under the prerequisite that does not deviate from the design concept of the utility model, the ordinary person in the art should fall into the protection scope of the utility model to the various changes and improvements that the technical scheme of the utility model made.

The technology, shape and construction parts which are not described in detail in the present invention are all known technology.

Claims (2)

1. Blast furnace belly pipe cooling tube instrument, its characterized in that, including arc pipe and oxygen hose, the arc pipe transversely installs in the front end of oxygen hose, and the radian of arc pipe is towards oxygen hose side, has seted up a plurality of apertures on the lateral wall of arc pipe towards oxygen hose one side, and the end of oxygen hose is passed through the reducing connecting pipe and is connected with quick-operation joint.
