Description

A cooling inner ring water filtration device for a casting and rolling mill Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically a cooling inner ring water filtration device for a casting and rolling mill. Background Technology

[0002] The production of aluminum alloy cast and rolled plates requires the circulation of cooling inner ring water within the core of the casting rolls. This water carries away the heat from the molten aluminum. However, the continuous contact between the cooling inner ring water and the inner wall of the pipes causes corrosion. The flaking rust severely affects the water quality. Furthermore, since the cooling inner ring water is located in a completely isolated and sealed area, this rust cannot be separated and will remain in the water for a long time, further deteriorating the water quality. This deterioration can cause blockages in the water channels within the casting roll core, leading to localized interruptions in the cooling inner ring water flow. This can range from minor issues like abrupt changes in roll shape at the point of interruption affecting the plate shape to more serious problems like roll sleeve cracking due to prolonged heat stress, rendering the equipment unusable.

[0003] Because the cooling inner ring water is in a completely isolated and sealed area, it cannot be cleaned and can only be replaced periodically. However, periodically replacing the cooling inner ring water will cause forced shutdowns during operation, affecting production efficiency. At the same time, periodically replacing large quantities of cooling inner ring water will also waste water resources, thereby increasing production costs. Moreover, the filtered cooling inner ring water can effectively remove the heat generated during the casting and rolling process, making the temperature field in the casting and rolling zone uniform and stable. This helps to improve the surface quality and internal microstructure of the cast and rolled products, and reduce product defects such as cracks and segregation caused by uneven cooling.

[0004] Based on this, a cooling inner ring water filtration device for casting and rolling mills is provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0005] The purpose of this invention is to provide a cooling inner ring water filtration device for casting and rolling mills, to solve the problem in the prior art where the cooling inner ring water is in a completely isolated and sealed area, making it impossible to clean and requiring periodic replacement. However, periodic replacement of the cooling inner ring water causes forced shutdowns during operation, affecting production efficiency. Furthermore, periodic large-scale replacement of the cooling inner ring water also wastes water resources, thereby increasing production costs. Moreover, the cleaned cooling inner ring water effectively removes the heat generated during the casting and rolling process, ensuring a uniform and stable temperature field in the casting and rolling zone. This helps improve the surface quality and internal microstructure of the cast and rolled products, reducing product defects such as cracks and segregation caused by uneven cooling.

[0007] A cooling inner ring water filtration device for a casting and rolling mill includes a first connecting pipe and a second connecting pipe. Both the first and second connecting pipes are externally fitted with flanges. Movable grooves are provided at the ends of the first and second connecting pipes.

An installation mechanism is provided on the outer side of the flanges 2. A filtration mechanism is provided between the flanges 2. By inserting the installation mechanism into the movable grooves 3, the flanges 2 can be quickly connected and installed, facilitating disassembly and maintenance. The limiting mechanism and the installation mechanism cooperate to achieve rapid limiting and fixing, improving stability. The flanges 2 are fixed together by bolts. The filtration mechanism can effectively achieve periodic filtration of the cooling inner ring water, significantly improving the water quality, stabilizing product quality, and ensuring safe equipment operation.

[0025] In one embodiment, as shown in FIG6, the limiting mechanism includes a first slide groove 6, which is symmetrically arranged on both sides of the first connecting pipe 1. A second slide groove 7 is provided on one side of the bottom end of the first slide groove 6, and a first limiting groove 8 is provided on the bottom side of the second slide groove 7 near the port. The first limiting groove 8 can limit and fix the limiting block 10.

[0026] In one embodiment, as shown in Figure 3, the installation mechanism includes a tube 9 located at the end of the second connecting tube 16, and the tube 9 corresponds to the position of the movable groove 3. A limiting block 10 is provided on the tube 9 at a position corresponding to the first sliding groove 6. The limiting block 10 is aligned with the first sliding groove 6, thereby inserting the tube 9 into the movable groove 3. The tube 9 presses the support plate 4 inward, and the support plate 4 presses the first spring 5 until the limiting block 10 slides to the bottom of the first sliding groove 6. The second connecting tube 16 is rotated counterclockwise to slide the limiting block 10 to the bottom of the second sliding groove 7. The second connecting tube 16 is released, and the support plate 4, under the action of the first spring 5 resetting, pushes the limiting block 10 into the first limiting groove 8 for limiting and fixing.

[0027] In one embodiment, as shown in Figure 2, the flange 2 is provided with a plurality of first mounting holes 11, and the inner side of the flange 2 is provided with mounting grooves 12 to facilitate the installation and fixing of the flanges 2.

[0028] In one embodiment, as shown in FIG2, a sealing gasket 13 is provided in the mounting groove 12, and a second mounting hole 14 is provided on the sealing gasket 13 at a position corresponding to the first mounting hole 11, thereby improving the sealing performance.

[0030] Working principle: During use, when assembling or disassembling flange 2, align the limiting block 10 with the first sliding groove 6, and insert the insertion tube 9 into the movable groove 3. The insertion tube 9 presses inward against the support plate 4, and the support plate 4 presses against the first spring 5 until the limiting block 10 slides to the bottom of the first sliding groove 6. Rotate the second connecting pipe 16 counterclockwise to slide the limiting block 10 to the bottom of the second sliding groove 7. Release the second connecting pipe 16, and the support plate 4, under the action of the first spring 5 resetting, pushes the limiting block 10 into the first limiting groove 8 for limiting and fixing.
