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.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide a modified metal hose connection for a tuyere small-sleeve cooling water pipe hard pipe, and solves the problems that in the prior art, the cooling water hard pipe is in contact extrusion with a middle sleeve or a belly pipe due to deformation or displacement caused by pressure and temperature change in a furnace, the hard pipe is subjected to bending deformation after being stressed, a pipe root and a small-sleeve sealing surface are damaged, a large amount of water is leaked, and the tuyere small-sleeve cooling water pipe hard pipe needs to be replaced when in serious condition, so that adverse effects are brought to blast furnace production.
The purpose of the invention 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 invention has the beneficial effects that:
1. the invention 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 phenomenon of water leakage of the pipe root is avoided, and the application effect is good;
2. according to the invention, the high-temperature asbestos is wrapped outside the metal hose, so that high-temperature damage is prevented, and the service life is prolonged;
3. the invention reduces the damping down time and eliminates the potential safety hazard.
