[0002] In the process of producing various steel products in steel mills, there are two methods of using molten steel to solidify and form: traditional mold casting and continuous steel casting. Continuous casting technology can greatly improve metal yield and ingot quality. During the production process, steelmaking continuous casting ingots must be cooled by cooling water. The steelmaking cold water sewage discharge device usually discharges sewage through filters.

[0003] For example, a steelmaking continuous casting sewage filter device with authorization announcement number "CN220345227U" filters through a built-in filter installed in a single stream, and then discharges sewage through a sewage valve, thereby improving water quality and reducing nozzle blockage, thereby improving the overall surface and internal quality of the continuous casting billet. However, since the filter screen of the steelmaking continuous casting sewage filter device cannot be disassembled, when there is a lot of steel residue on the filter screen that needs to be cleaned, it takes the operator a long time to clean it, thereby reducing work efficiency. At the same time, the steelmaking continuous casting sewage filter device uses the operator to manually turn the hand crank to drive the wire brush to clean the filter screen. Since the operator needs to manually turn it, it consumes more physical strength of the operator, thereby increasing manual labor. Utility Model Content

[0031] Preparation process:

[0032] First, open the water inlet flange 12, and insert the filter screen 11 along the inner wall of the sewage filter body 3. When the end of the filter screen 11 stops inserting with the end cover flange 8, start the power supply of the first motor 402 below. The output shaft of the first motor 402 rotates clockwise to drive the worm 403 to rotate, thereby driving the worm gear 404 to rotate.

Similarly, the power supply of the first motor 402 above is started to make the output shaft of the first motor 402 rotate counterclockwise. When the teeth at the end of the rocker 405 are engaged with the tooth grooves machined on the rack 406, the rack 406 moves downward to the maximum distance, and the power supply of the first motor 402 above is turned off. When the rack 406 moves to the maximum distance, the end of the rack 406 is pressed against the inner wall of the groove machined on the filter 11, so that the filter 11 can be disassembled. When the filter 11 needs to be cleaned, it is more convenient and takes less time.

[0033] Steelmaking continuous casting sewage discharge process:

[0034] Connect the sewage discharge pipe to the end of the sewage inlet pipe 10, open the valve on the sewage inlet pipe 10, so that the sewage enters the sewage filter body 3 from the sewage inlet pipe 10 through the outlet pipe 9 and the filter screen 11. The filter screen 11 can filter out the steel residue in the sewage. When there is a lot of filter screen residue, start the power supply of the hydraulic cylinder 602, and the telescopic end of the hydraulic cylinder 602 moves back and forth to drive the slider 603 to slide back and forth along the slide groove processed on the protruding part of the inner wall of the second shell 601. The slider 603 moves back and forth to drive the transmission rod 604 to The rotating rod 605 moves back and forth, thereby driving the rotating rod 605 to rotate, the rotating rod 605 drives the first gear 606 and the second gear 607 to rotate, the second gear 607 drives the rotating shaft 608 to rotate, the rotating shaft 608 drives the rotating roller 7 to rotate, thereby driving the wire brush on the surface of the rotating roller 7 to clean the steel residue on the filter screen 12, so that the sewage can more easily enter the sewage filter body 3, open the valve on the sewage pipe 2, and discharge the sewage from the sewage pipe 22, without the operator consuming much physical strength, thereby saving manual labor.

[0035] Sewage filter inner wall cleaning process:

[0036] The operator opens the water inlet pipe flange 12, starts the power supply of multiple first motors 402, makes the output shaft of the lower first motor 402 rotate counterclockwise, and the output shaft of the upper first motor 402 rotates clockwise, driving the multiple racks 406 to reset, then takes out the filter screen 11, opens the valve of the discharge port, allows the filtered steel residue to be discharged from the discharge port, then closes the discharge port, the valves on the sewage pipe 2 and the sewage inlet pipe 10, reinstalls the water inlet pipe flange 12, starts the water pump, pumps the water in the water tank into the cold water inlet pipe 13, cleans the inner wall of the sewage filter body 3 until the water is discharged from the outlet pipe 9, and after cleaning, turns off the water pump power supply, opens the sewage pipe 2 valve, and allows the water on the inner wall of the sewage filter body 3 to be completely discharged.
