Description

Technical Field

[0001] The utility model relates to the technical field of cooling water slag removal, in particular to a cooling water slag removal device. Background Technique

[0002] At present, most of the cooling water used in steel mills is directly extracted from the river water by pumps and used in the steel-making process. However, the river water contains certain impurities. Long-term use is likely to cause failures in the cooling equipment, reduce the cooling effect, and affect the steel-making quality and efficiency.

[0003] The existing Chinese utility model patent with the reference publication number: CN219409317U discloses a water treatment device, especially a cooling water filtration system for steel-making, including a filtration tank, a sewage discharge pipe and a clean water outlet arranged at the bottom of the filtration tank. A number of filtration layers are arranged in the filtration tank, and a sewage discharge port is arranged at the bottom of the front side of each filtration layer, and the sewage discharge port is connected to the sewage discharge pipe. The utility model improves the quality of the cooling water for steel-making, thereby improving the steel-making cooling effect, reducing the equipment failure rate, and improving the steel-making quality and efficiency.

[0004] The existing cooling water slag removal equipment generally filters the cooling water through a filtration tank and filtration layers. In this way, the cooling water naturally penetrates through the filtration layers, and the penetration of the cooling water is slow and takes a long time, resulting in a reduction in filtration efficiency. At the same time, the filtration layers are generally formed by piling up filter materials such as sand and gravel. After long-term use, the permeability of the filtration layers will decrease due to the accumulation of impurities. The filtration layers need to be replaced or scattered and cleaned after being used for a period of time. Since the filter materials are piled up inside the filtration tank, the existing filtration structure cannot quickly take out the filter materials inside the filtration tank at one time when replacing the filtration layers, which is very inconvenient.

[0015] Compared with the prior art, the utility model provides a cooling water slag removal device, which has the following beneficial effects:

[0016] 1. The utility model sets a metal frame, which is fixedly installed at the center of the limiting plate. The limiting plate can limit the metal frame to be located at the center of the inner cavity of the limiting tube, so that an annular cavity is left between the metal frame and the limiting tube.

The centrifugal force generated by the cooling water during rotation compresses the cooling water toward the outer edge of the baffle, so that the water pressure increases, so that the cooling water can quickly penetrate into the filter material, thereby improving the slag removal efficiency.
