[0018] Reference Figures 1 to 4This utility model discloses a rapid cooling device for hot-rolled seamless steel pipes, comprising a main body 1. A filter chamber 3 is fixedly connected to the side surface of the main body 1. Positioning plates 2 are fixedly connected to the upper surface of the filter chamber 3 near both ends. Threaded rods 10 are rotatably connected to the side surfaces of the positioning plates 2. Sliding blocks 5 are slidably connected to the upper surface of the filter chamber 3. Threaded holes are formed on both sides of the sliding blocks 5 near the threaded rods 10, and the threaded holes engage with the threaded rods 10. A through groove 15 is formed on the upper surface of the filter chamber 3 near the threaded rods 10. An insert 16 is fixedly connected to the lower surface of the sliding blocks 5. A storage groove is formed on the lower inner surface of the filter chamber 3. A filter plate 11 is installed inside the material tank. A fixing sleeve 17 is fixedly connected to the upper surface of the filter plate 11. A square groove is opened on the inner surface of the filter chamber 3 near the insertion post 16. A rocker arm 6 is rotatably connected to the side surface of the positioning plate 2. The insertion post 16 is L-shaped and passes through the through groove 15. One end of the threaded rod 10 passes through the positioning plate 2 and is fixedly connected to the rocker arm 6. A second pump 21 is fixedly connected to the side surface of the main body 1 near the filter chamber 3. A water storage tank 9 is fixedly connected to the output end of the second pump 21. A water supply pipe 4 is fixedly connected to the input end of the second pump 21. The other end of the water supply pipe 4 is fixedly connected to the side surface of the filter chamber 3. The bottom of the interior of the main body 1 is sloped to facilitate the flow of water into the filter chamber 3.

[0019] A positioning groove is provided on the side surface of the water storage tank 9, and a transparent observation plate 19 is fixedly connected in the positioning groove. Multiple nozzles 14 are fixedly connected to the lower surface of the diversion plate 13. The input end of the pump 20 passes through the main body 1 and is fixedly connected to the lower surface of the water storage tank 9. The upper surface of the main body 1 is fixedly connected to the lower surface of the water storage tank 9. The pump 20 is fixedly connected to the upper inner surface of the main body 1, and the diversion plate 13 is fixedly connected to the output end of the pump 20. A protective shell is provided on the upper surface of the filter chamber 3 near the threaded rod 10. Its design aims to visually display the internal components, and therefore it is not depicted in the illustration.

[0020] Mounting pins 8 are installed in the mounting holes and threaded holes. A support platform 12 is fixedly connected to the inner surface of the main body 1 near the nozzle 14. A fixing plate 7 is installed on the side surface of the filter chamber 3 near the threaded hole. Mounting holes are opened on the side surface of the fixing plate 7 near the threaded hole. A water inlet 18 is fixedly connected to the upper surface of the water storage tank 9. A threaded hole is opened at one end of the filter chamber 3. There is a certain distance between the threaded rod 10 and the filter plate 11, so the water flow is unlikely to affect the threaded rod 10.

[0021] Working Principle: When using this equipment, the workpiece is first placed on the support platform 12. Then, pump 20 is started to draw water from the water tank 9 and deliver it to the diversion plate 13. Subsequently, the water flows through the diversion plate 13 into the nozzle 14, which evenly sprays the water onto the workpiece surface for heat dissipation. After heat dissipation, the water flows through the holes on the support platform 12 into the bottom of the main body 1. Because the bottom of the main body 1 is designed with a slope, the water flow is guided towards the filter chamber 3. The filter plate 11 in the filter chamber 3 effectively blocks impurities in the water flow, preventing damage to pump 21, the water supply pipe 4, and pump 20. Afterwards, by starting pump 21, the water flow returns to the water tank 9 through the water supply pipe 4, achieving water recycling and reducing resource waste. However, because the filter plate 11 blocks impurities in the water flow for a long time, wear is inevitable, therefore, it needs to be replaced and maintained regularly. To disassemble the filter plate 11, first remove the mounting pins 8 from the mounting holes and threaded holes, thus releasing the fixing plate 7. Then, rotate the rocker arm 6 in the opposite direction to move the sliding block 5, causing the insert 16 to disengage from the square groove and the fixing sleeve 17, thereby releasing the fixing of the filter plate 11. At this point, the filter plate 11 can be easily removed for maintenance or replacement. After the filter plate 11 has been maintained or replaced, place it back into the storage slot. Next, rotate the rocker arm 6 clockwise to gradually move the insert 16 toward the fixing sleeve 17 until the insert 16 is fully embedded in the square groove and abuts against its inner wall, thus achieving the limiting and fixing of the filter plate 11. Finally, reinstall the corresponding mounting pins 8 to complete the entire installation process of the filter plate 11.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
