Description

Technical Field

[0001] This utility model relates to the field of mixing nozzle technology, specifically a high-temperature resistant gas-water mixing nozzle device for cooling hot-rolled wire rod. Background Technology

[0002] In the production of hot-rolled wire rod, high-temperature wire rod needs to be rapidly and uniformly cooled through air-water mixing nozzles to optimize the material's mechanical properties. Traditional single-orifice nozzle designs result in larger water droplet sizes, low cooling uniformity, and negatively impact the consistency of product mechanical properties. Furthermore, ordinary stainless steel nozzles corrode rapidly in high-temperature, humid environments, leading to frequent replacements and increased downtime costs. Additionally, the integral structure requires complete replacement after localized wear, resulting in low maintenance efficiency. While existing technologies may already address these issues, this paper aims to provide an alternative or replacement solution. Utility Model Content

[0003] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-temperature resistant gas-water mixing nozzle device for cooling hot-rolled wire rod, comprising an outer gas pipe, eight gas guide strips installed on the inner wall of the outer gas pipe, a nozzle structure installed on one side of the outer gas pipe, and a liquid conveying structure installed between the eight gas guide strips;

[0004] The nozzle structure includes: a threaded sleeve, a connecting sleeve, a mounting frame, and a ceramic-lined nozzle;

[0005] One end of the threaded sleeve is fixedly installed on one end of the outer air pipe, one end of the connecting sleeve is movably embedded in the other side of the threaded sleeve, the mounting frame is fixedly installed in the connecting sleeve, and the ceramic liner nozzle is fixedly installed in the mounting frame.

[0006] Preferably, the liquid delivery structure includes: an inner liquid tube, a dispensing head, and six dispensing holes;

[0007] The outer wall of the inner liquid tube is connected to the inner wall of the eight gas guide strips. The liquid separator head is fixedly installed on one side of the inner liquid tube, and the six liquid separator holes are all opened at the upper end of the liquid separator head.

[0008] Preferably, the six dispensing holes are inclinedly opened at the upper end of the dispensing head.

[0009] Preferably, the inclination angle of the dispensing orifice is 30 degrees.

[0010] Preferably, the eight gas guide strips are spirally distributed between the outer gas tube and the inner liquid tube.

[0011] Preferably, the connection position between the connecting sleeve and the threaded sleeve is machined with external threads.

[0012] Beneficial effects

[0013] This utility model provides a high-temperature resistant gas-water mixing nozzle device for cooling hot-rolled wire rod, which has the following beneficial effects: Based on the synergistic effect of eight spirally distributed gas guide strips and 30° inclined distributing holes, the gas forms a high-speed swirling flow that cuts the water flow, effectively reducing the water droplet size, significantly improving cooling uniformity, and reducing the temperature difference on the wire surface. At the same time, the ceramic-lined nozzle increases the overall high-temperature corrosion resistance of the nozzle, ensuring the overall service life of the nozzle. The modular nozzle structure allows for quick assembly and disassembly through a threaded sleeve and a connecting sleeve with external threads. When there is local wear, only the ceramic-lined nozzle needs to be replaced, avoiding complete scrapping. The six 30° inclined holes at the upper end of the distributing head, combined with the gas swirling flow, improve the gas-water mixing efficiency and reduce the consumption of compressed air.

[0018] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Example: Please refer to Figure 1-3 A high-temperature resistant gas-water mixing nozzle device for cooling hot-rolled wire rod includes an outer gas pipe 1, eight gas guide strips 2 installed on the inner wall of the outer gas pipe 1, a nozzle structure installed on one side of the outer gas pipe 1, and a liquid conveying structure installed between the eight gas guide strips 2.

[0020] The nozzle structure includes: threaded sleeve 3, connecting sleeve 4, mounting frame 5, and ceramic-lined nozzle 6;

[0021] One end of the threaded sleeve 3 is fixedly installed on one end of the outer air pipe 1, one end of the connecting sleeve 4 is movably embedded in the other side of the threaded sleeve 3, the mounting frame 5 is fixedly installed in the connecting sleeve 4, and the ceramic lining nozzle 6 is fixedly installed in the mounting frame 5.

[0022] The liquid delivery structure includes: an inner liquid tube 7, a liquid distributor 8, and six liquid distributor holes 9;

[0023] The outer wall of the inner liquid tube 7 is connected to the inner wall of the eight gas guide strips 2. The liquid separator 8 is fixedly installed on one side of the inner liquid tube 7, and the six liquid separator holes 9 are all opened on the upper end of the liquid separator 8.

[0024] When assembling the nozzle, the ceramic-lined nozzle 6 is first embedded into the mounting frame 5 on the inside. Then, the ceramic-lined nozzle 6 is installed by connecting the sleeve 4 and threaded sleeve 3. Next, the outer air pipe 1 is connected to the gas pipeline, and the inner liquid pipe 7 is connected to the liquid delivery pipeline. When cooling the hot-rolled wire, the gas is guided by eight gas guide strips 2 located between the outer air pipe 1 and the inner liquid pipe, so that the gas forms a swirling gas. Under the action of the liquid distribution hole 9 opened on the liquid distribution head 8 at one end of the inner liquid pipe 7, the water flow is diffused through the six liquid distribution holes 9, and the water mist is wrapped by the swirling gas, which improves the gas-water mixing efficiency and reduces the consumption of compressed air. Finally, the fully mixed water and gas are sprayed out through the ceramic-lined nozzle 6 in the mounting frame 5 to cool the hot-rolled wire.

[0025] In the specific implementation process, six dispensing holes 9 are inclinedly opened at the upper end of the dispensing head 8.

[0026] In the specific implementation process, the tilt angle of the liquid separator 9 is 30 degrees, and the six 30° tilted holes at the top of the liquid separator 8 work together with the gas swirl to improve the gas-water mixing efficiency and reduce the consumption of compressed air.

[0027] In the specific implementation process, eight gas guide strips 2 are spirally distributed between the outer gas pipe 1 and the inner liquid pipe 7. Through the eight spirally distributed gas guide strips 2, the gas forms a swirling gas that envelops the water mist.

[0028] In the specific implementation process, the connection position between the connecting sleeve 4 and the threaded sleeve 3 is machined with external threads. By cooperating with the threaded sleeve 3, the ceramic lining nozzle 6 can be quickly connected, ensuring the efficiency of subsequent maintenance.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
