Description

Technical Field

[0001] This utility model relates to the field of stainless steel strip technology, specifically to a stainless steel strip cooling device. Background Technology

[0002] Stainless steel strip is a strip-shaped metal product made from stainless steel through a rolling process. Its width is usually smaller than that of stainless steel sheet, but its length can be flexibly customized according to requirements. This strip material retains the inherent corrosion resistance, oxidation resistance, and mechanical strength of stainless steel, while exhibiting unique advantages in industrial applications due to its special geometric shape.

[0003] In the production of stainless steel strip, cooling water, as a critical process medium, directly affects the surface quality and production efficiency of the strip. With prolonged circulation, a large amount of particulate impurities inevitably accumulate in the cooling water. These impurities come from various sources, including tiny oxide particles detached from the strip surface, metal debris from equipment wear, sediment from the inner walls of pipes, and dust introduced from the external environment. Although these suspended solid particles are small, they impact the strip surface with high kinetic energy under the influence of the cooling water, causing scratches.

[0004] While directly replacing contaminated cooling water after prolonged use can temporarily solve the problem, this method has significant drawbacks from a sustainable production perspective. Modern stainless steel production lines can circulate tens of tons of cooling water per hour. Frequent water changes not only significantly increase production costs but also contradict the currently advocated green manufacturing concept. Utility Model Content

[0005] The purpose of this utility model is to provide a stainless steel strip cooling device that facilitates the filtration and recirculation of cooling water used for extended periods, preventing impurities in the cooling water from scratching the surface of the steel strip. It also saves water resources. This solves the problem that after stainless steel strip production, cooling water is needed for cooling, but prolonged use results in the cooling water containing a large amount of particulate impurities that can scratch the surface of the steel strip. Furthermore, directly replacing the cooling water without treatment leads to water waste.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel strip cooling device, comprising a water tank, a steel strip body, a circular box, and a threaded disc. A water trough is formed on the upper surface of the water tank, and a second rotating roller is rotatably connected to the inner wall of the water trough.

[0007] Preferably, the steel strip body extends through the space between two upper and lower rollers on both sides, with the upper surface of the steel strip body located at the lower end of the second roller. The use of rollers facilitates the transport and cooling of the steel strip body.

[0008] Preferably, the lower surface of the water tank has a second mounting hole, the upper end of the outer wall of the first pipe extends into the second mounting hole and is fixed therein, and the upper surface of the threaded cap has a third mounting hole, the lower end of the outer wall of the first pipe extends into the third mounting hole and is fixed therein. The second and third mounting holes facilitate the fixing of the first pipe and also facilitate the introduction of cooling water from the water tank into the circular groove.

[0009] Preferably, a handle is fixed to each of the two sides of the outer wall of the cylindrical box. The handle facilitates the rotation of the cylindrical box and the installation and removal of the threaded cover and the cylindrical box.

[0010] Preferably, the upper surface of the disc has a threaded hole, the threaded disc extends into the threaded hole and is threadedly connected, and two handles are fixed on both sides of the upper surface of the threaded disc. The two handles facilitate rotation of the threaded disc, making it easy to install and remove the threaded disc, and also facilitate the replacement of the filter screen.

The second and third pipes facilitate the return flow of the filtered cooling water.

[0012] Preferably, the water tank is fixed with support columns at both the front and rear ends on both sides. These support columns facilitate the support of the water tank and make the overall device easier to use.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

The filtered cooling water then flows back into the water tank through the second and third pipes. This facilitates the filtration and return of cooling water used for extended periods, preventing impurities in the cooling water from scratching the surface of the steel strip body, while also conserving water resources.

The front ends of the fixing plates 4 are rotatably connected to the first roller 5. The steel strip body 3 passes through the upper and lower rollers 5 on both sides. The upper surface of the steel strip body 3 is located at the lower end of the second roller 8. The first roller 5 and the second roller 8 facilitate the transmission of the steel strip body 3 and facilitate the cooling of the steel strip body 3.

[0024] A pipe 11 is fixed to the lower surface of the water tank 2. A threaded cap 14 is fixed to the bottom end of the pipe 11. A second mounting hole 10 is opened on the lower surface of the water tank 2. The upper end of the outer wall of the pipe 11 extends into the second mounting hole 10 and is fixed. A third mounting hole 15 is opened on the upper surface of the threaded cap 14. The lower end of the outer wall of the pipe 11 extends into the third mounting hole 15 and is fixed. The second mounting hole 10 and the third mounting hole 15 facilitate the fixing of the pipe 11 and at the same time facilitate the introduction of cooling water in the water tank 7 into the circular groove 23.

[0025] The upper surface of the circular box 6 is provided with a threaded groove 13. Handles 12 are fixed on both sides of the outer wall of the circular box 6. The handles 12 facilitate the rotation of the circular box 6 and the installation and removal of the threaded cover 14 and the circular box 6. The bottom of the inner wall of the threaded groove 13 is provided with a circular groove 23. A disc 19 is fixed on the inner wall of the circular groove 23. The disc 19 is threadedly connected to the threaded disc 20. The upper surface of the disc 19 is provided with a threaded hole 16. The threaded disc 20 extends into the threaded hole 16 and is threadedly connected. Handles 28 are fixed on both sides of the upper surface of the threaded disc 20. The handles 28 facilitate the rotation of the threaded disc 20 and the installation and removal of the threaded disc 20. It is also convenient to replace the filter screen 21. The upper surface of the threaded disc 20 is provided with a circular hole 17. The inner wall of the circular hole 17 is fixed with a filter screen 21. The filter screen 21 can filter impurities in the cooling water after long-term use and prevent impurities in the cooling water from scratching the surface of the steel strip body 3. The threaded cover 14 extends into the threaded groove 13 and is threadedly connected.

[0026] Pipe 24 is fixed to the lower surface of the cylindrical box 6. A water pump 25 is installed at the top of pipe 24. Pipe 3 26 is installed at the upper end of water pump 25. The front end of pipe 3 26 is fixed to the rear end of water tank 2. A mounting hole 4 22 is opened on the lower surface of the cylindrical box 6. The outer wall of pipe 24 extends into the mounting hole 4 22 and is fixed. A mounting hole 1 9 is opened at the rear end of water tank 2. The front end of the outer wall of pipe 3 26 extends into the mounting hole 1 9 and is fixed. The filtered cooling water can be returned through pipe 2 24 and pipe 3 26.

[0027] Pump 25 provides power for the transport of filtered cooling water, enabling the filtered cooling water to be returned, thus saving water resources.

[0028] The water pump 25 mainly consists of core components such as an impeller, pump casing, main shaft, and sealing device. The impeller generates centrifugal force through high-speed rotation, throwing liquid from the center to the edge, creating a low-pressure zone that draws in liquid. The pump casing guides the thrown liquid tangentially into the outlet pipe, simultaneously converting kinetic energy into pressure energy. The main shaft connects the power source and the impeller, while bearings and sealing rings ensure smooth operation and prevent leakage.

[0029] Its working principle is based on the combined effect of centrifugal force and atmospheric pressure. Before starting, it needs to be filled with water. When the impeller rotates, the liquid is thrown out by centrifugal force, creating a vacuum low-pressure zone at the center of the impeller. External liquid is then replenished through the inlet pipe under atmospheric pressure. Self-priming pumps, on the other hand, do not require pre-priming; they directly utilize negative pressure to complete the water suction process.

[0030] When cooling of the steel strip body 3 is required, cooling water is poured into the water tank 7. The steel strip body 3 is then transported by rollers 5 and 8. During transport, the cooling water cools the steel strip body 3. After prolonged use, pipe 11 becomes open, and the cooling water enters the circular trough 23 through pipe 11. The filter screen 21 filters the cooling water. Finally, the water pump 25 is activated, causing the filtered cooling water to flow back into the water tank 7 through pipes 24 and 26. This facilitates the filtration and return of cooling water used for extended periods, preventing impurities in the cooling water from scratching the surface of the steel strip body 3, while also conserving water resources.
