Description

Technical Field

[0001] This utility model relates to the field of blast furnace tuyeres technology, and in particular to a blast furnace tuyeres cooling device with supporting function. Background Technology

[0002] The blast furnace tuyeres are an important piece of equipment in the blast furnace air intake system. They are installed in the furnace wall between the furnace belly and the hearth and are composed of three parts: a large sleeve, a medium sleeve, and a small sleeve.

[0003] During blast furnace ironmaking, hot air is introduced into the furnace through the tuyere sleeve to smelt the raw metal ore. However, the temperature of the hot air is usually quite high, and the furnace body will vibrate during operation. During blast furnace production, the tuyere sleeve may be severely damaged due to thermal stress inside the furnace, unreasonable brick lining construction, poor material, and especially frequent furnace shutdowns and restarts. Damaged brick lining can easily lead to loosening of the blast furnace tuyere sleeve, posing a great safety hazard. Utility Model Content

A cooling ring 3 is snapped onto the outer side of the blast furnace tuyere sleeve 1. A cooling chamber 2 is opened inside the cooling ring 3. A cooling mechanism is provided on the inner side of the cooling chamber 2. A bracket 8 is fixedly installed on the outer side of the blast furnace tuyere sleeve 1. Multiple support mechanisms are provided on one side of the bracket 8.

[0021] In this embodiment, the cooling mechanism includes an inlet pipe 4, a cooling water pipe 5, and an outlet pipe 6. The cooling water pipe 5 is fixedly installed inside the cooling chamber 2. One end of the cooling water pipe 5 is fixedly installed with the inlet pipe 4, and the other end of the cooling water pipe 5 is fixedly installed with the outlet pipe 6.

[0022] In this embodiment, a cooling tower 7 is provided on one side of the blast furnace tuyeres 1. A water outlet and a water inlet are provided on one side of the cooling tower 7. The water inlet pipe 4 is connected to the water outlet, and the water outlet pipe 6 is connected to the water inlet, which facilitates the recycling of the coolant.

[0023] In this embodiment, the support mechanism includes a stabilizing sleeve 9, a threaded sleeve 10, a pile assembly, and a pressing assembly. The stabilizing sleeve 9 is fixedly inserted through the bracket 8. The threaded sleeve 10 is rotatably installed on the inner side of the stabilizing sleeve 9. A pile assembly is provided on one side of the threaded sleeve 10. A pressing assembly is provided on the pile assembly to facilitate the fixing of the blast furnace tuyeres sleeve 1 to the furnace wall.

[0024] In this embodiment, the pile assembly includes a threaded rod 11 and a pile body 13. One end of the threaded sleeve 10 is threaded with the threaded rod 11, and the other end of the threaded rod 11 is fixedly installed with the pile body 13, so that the pile body 13 can be moved by the threaded rod 11.

[0025] In this embodiment, the outer side of the stabilizing sleeve 9 is provided with a plurality of sliding grooves 16, and the inner side of the stabilizing sleeve 9 is provided with two guide grooves.

[0026] In this embodiment, the extrusion assembly includes an extrusion metal ring 12 and a plurality of extrusion metal blocks 14. The plurality of extrusion metal blocks 14 are slidably installed on the inner side of the corresponding sliding groove 16. The extrusion metal ring 12 is fixedly sleeved on the outer side of the pile body 13. The extrusion metal ring 12 is in contact with the plurality of extrusion metal blocks 14. The outer side of the extrusion metal ring 12 is provided with two protrusions, which are slidably installed in the corresponding guide grooves.

[0027] In this embodiment, metal spikes 15 are fixedly installed on one side of each of the multiple extruded metal blocks 14 to help stabilize the multiple extruded metal blocks 14 in the mounting groove of the furnace wall.

[0028] Working principle: During installation, the workers first assemble the blast furnace tuyeres sleeve 1 with the cooling ring 3. Then, they connect the inlet pipe 4 and outlet pipe 6 on the cooling ring 3 to the cooling tower 7. This allows the coolant to enter the cooling water pipe 5 through the inlet pipe 4 for heat exchange during operation of the blast furnace tuyeres sleeve 1, and then be discharged into the cooling tower 7 through the outlet pipe 6. After cooling, the system circulates again, thus reducing the temperature of the blast furnace tuyeres sleeve 1. After installing the blast furnace tuyeres sleeve 1 on the furnace wall, the workers align the bracket 8 with the blast furnace tuyeres sleeve 1 and weld it. Then, the bracket 8 contacts the furnace wall, and an installation groove is cut into the furnace wall using tools. The installation groove must be compatible with the radius of the threaded sleeve 10. Finally, the four threaded sleeves 10 are rotated. The rod 11 is fixedly connected to the pile body 13. A compression metal ring 12 is fixedly sleeved on the pile body 13. Both sides of the compression metal ring 12 are provided with protrusions. Two guide grooves are opened on the inner side of the stabilizing sleeve 9. The two protrusions are slidably installed in the corresponding guide grooves. Therefore, the threaded rod 11 cannot rotate. The rotation of the threaded sleeve 10 drives the threaded rod 11 to move. The movement of the threaded rod 11 drives the pile body 13 to contact the furnace wall and penetrate into the furnace wall. When the pile body 13 moves to the designated position, it drives the compression metal ring 12 to move to the designated position, compressing multiple compression metal blocks 14 and causing them to slide outward, driving the metal spikes 15 to penetrate into the inner wall of the installation groove. Then, the gap between the installation groove and the stabilizing sleeve 9 is filled with cement or other materials to complete the installation.

[0029] The technological advancements of this invention compared to existing technologies are as follows: the cooling mechanism can cool the blast furnace tuyeres 1, preventing it from overheating and melting; at the same time, the support mechanism can make the blast furnace tuyeres 1 more securely connected to the furnace wall, preventing it from falling off and causing production accidents, thus increasing the practicality and safety of the equipment.
