Abstract

The utility model discloses a tuyere small sleeve cooling water pipe hard tube reforms transform metal collapsible tube and connects, wherein include well cover, belly pipe, reform transform linking module, flange. The improved connecting module comprises a small sleeve, a cooling water pipe hard pipe, a metal hose and a quick connector. The utility model can adopt the metal hose to replace the traditional cooling water hard pipe, the length of the metal hose can be freely adjusted, the operation is convenient, the deformation can be effectively absorbed, the water leakage phenomenon of the pipe root is avoided, and the application effect is good; high-temperature asbestos wraps the metal hose to prevent high-temperature damage and prolong the service life; the damping down time is reduced, and the potential safety hazard is eliminated. The problem of among the prior art because of the furnace internal pressure, temperature variation produces deformation or aversion, causes the cooling water hard tube and well cover or belly pipe contact extrusion, produces bending deformation after the hard tube atress, makes the sealed face of pipe root and little cover damage and leak a large amount of water, must break down the wind and change when serious, brings adverse effect for blast furnace production is solved.

Description

Metal hose connection modified from hard pipe of tuyere small sleeve cooling water pipe

Technical Field

The utility model belongs to condenser tube hard tube reforms transform the field, concretely relates to tuyere small jacket condenser tube hard tube reforms transform metal collapsible tube and connects.

Background

In the field of blast furnace calcination manufacturing, a tuyere small sleeve, a middle sleeve and a belly pipe are indispensable air supply devices, wherein the tuyere small sleeve, the middle sleeve and the belly pipe are deformed or displaced due to the pressure in a furnace and the temperature change in the normal use process, so that a cooling water hard pipe is in contact extrusion with the middle sleeve or the belly pipe, the hard pipe is bent and deformed after being stressed, a pipe root and a small sleeve sealing surface are damaged and leak water in a large amount, and the tuyere small sleeve, the middle sleeve and the belly pipe are required to be blown down and replaced in serious conditions, so that adverse effects are brought to the blast furnace production. Therefore, the improved pipe connection mode which can replace a cooling water hard pipe, can effectively absorb deformation and avoid the phenomenon of water leakage of a pipe root is adopted, and the improved pipe connection mode meets the actual requirement.

Aiming at the problems provided above, the air port small sleeve cooling water pipe hard pipe is designed to be transformed into the metal hose connection.

SUMMERY OF THE UTILITY MODEL

An insufficient to prior art, an object of the utility model is to provide a tuyere small jacket condenser tube hard tube reforms transform metal collapsible tube and connects, solved among the prior art because of the stove internal pressure, temperature variation produces and warp or shift, causes the condenser tube to contact the extrusion with well cover or belly pipe, produces bending deformation after the hard tube atress, makes the root of pipe and the sealed face of small jacket damage and leak in a large number, must calm down when serious and change, brings adverse effect's problem for blast furnace production.

The purpose of the utility model can be realized by the following technical scheme:

the improved metal hose connection of the tuyere small sleeve cooling water pipe hard pipe comprises a middle sleeve, a belly pipe and an improved connection module, wherein the improved connection module comprises a small sleeve, a cooling water pipe hard pipe, a metal hose and a quick connector, the quick connector is arranged on the small sleeve, and the cooling water pipe hard pipe and the metal hose are connected with the quick connector.

Further, the small sleeve is arranged in the middle sleeve, and the belly pipe is arranged in the small sleeve.

Furthermore, a flange is arranged on the belly pipe.

The utility model has the advantages that:

1. the utility model can adopt the metal hose to replace the traditional cooling water hard pipe, the length of the metal hose can be freely adjusted, the operation is convenient, the deformation can be effectively absorbed, the water leakage phenomenon of the pipe root is avoided, and the application effect is good;

2. the utility model wraps the high temperature asbestos outside the metal hose, thereby preventing high temperature damage and prolonging service life;

3. the utility model discloses reduce the time of damping down, eliminated the potential safety hazard.
