[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] Reference Figures 1-4 As shown, a billet cooling device for a steelmaking continuous casting cooling bed includes a cooling pool 1 with two symmetrically distributed side plates 2 fixedly connected to its upper surface. An air pump 14 is fixedly installed on the front side of the cooling pool 1, with an air supply pipe 15 connected to the output end of the air pump 14. A circulation pipe 16 is connected to the rear end of the air supply pipe 15. The outer surface of the circulation pipe 16 is fixedly connected to one side opposite to the two side plates 2, and multiple evenly distributed nozzles 17 are connected to the outer surface of the circulation pipe 16. A support plate 12 is fixedly connected to the front side of the cooling pool 1, and a water pump 13 is fixedly installed on the upper surface of the support plate 12. A water supply pipe 18 is connected to the output end of the water pump 13, and the rear end of the water supply pipe 18 is connected to another circulation pipe 16. A water inlet pipe 19 is connected to the input end of the water pump 13, and a sleeve 20 is provided at the rear end of the water inlet pipe 19. Multiple conveying rollers 23 are rotatably connected between the two side plates 2.

[0024] Specifically, the two circulation pipes 16 are supported by the cooling pool 1 and the side plate 2. The side plate 2 also secures the air supply pipe 15 and the water supply pipe 18 to prevent them from falling off during use. The air pump 14 is also secured by the cooling pool 1, ensuring stable operation. Gas is then supplied through the air supply pipe 15, which connects to the circulation pipes 16. This allows the gas to pass through the circulation pipes 16 and the nozzles 17 on them, providing initial cooling to the casting and blowing off the oxide layer. The water pump 13, supported by the support plate 12, draws water from the cooling pool 1 through the inlet pipe 19, and then sends the water into another circulation pipe 16 through the outlet pipe 18. The water is then cooled by the spray pipe 17. At the same time, the suction of the water pump 13 drives the water flow, which in turn drives the fan blade 21 inside the sleeve 20 to rotate, thereby driving the sleeve 20 and the screen 22 to rotate. This facilitates the removal of impurities blocking the back of the screen 22 without affecting the water pump 13's suction.

[0025] Reference Figures 1-3As shown, a screen 22 is fixedly connected to the rear end of the sleeve 20, and a fan blade 21 is fixedly connected to the inner cavity of the sleeve 20; a top plate 3 is fixedly connected to the upper side of the cooling pool 1, and two symmetrically distributed sliding grooves 4 are opened through the inside of the top plate 3; two symmetrically distributed sliding plates 5 are slidably connected inside the top plate 3, and a rack 9 is fixedly connected to the left side of the inner wall of the top plate 3; a rotary motor 7 is fixedly installed on the lower surface of each of the two sliding plates 5, and the output ends of the two rotary motors 7 pass through the sliding plates 5 and are fixedly connected to guide rollers 6; a connecting plate 8 is fixedly connected to the lower surface of each of the two sliding plates 5, and a worm gear reducer 10 is fixedly installed on the left side of each of the two connecting plates 8; a gear 11 is fixedly connected to the output end of each of the two worm gear reducers 10, and the gear 11 meshes with the rack 9;

[0026] Specifically, the cooling pool 1 supports and fixes the top plate 3 above, and the top plate 3 also supports the movement of the casting. The sliding plate 5 inside the top plate 3 supports and fixes the guide roller 6 and the connecting plate 8. The worm gear reducer 10 fixed on the connecting plate 8 drives the gear 11 to move on the rack 9, thereby driving the sliding plate 5 to slide inside the top plate 3. This allows the guide roller 6 above the sliding plate 5 to move. At the same time, the output end of the rotary motor 7 moves through the groove 4 on the top plate 3. The rotary motor 7 below the sliding plate 5 drives the guide roller 6 above to rotate. The casting is then clamped and moved by the two relatively rotating guide rollers 6, achieving the effect of transporting castings of different sizes.

[0027] Working principle: During use, the worm gear reducer 10 below the top plate 3 drives the gear 11 to rotate, thereby moving the position of the slide plate 5. At the same time, it drives the guide roller 6 on the slide plate 5 to move, so as to adjust according to the different sizes of the continuous casting. Meanwhile, the rotary motor 7 directly connected to the guide roller 6 below the slide plate 5 drives the guide roller 6 to rotate, thereby conveying the continuous casting. The multiple conveying rollers 23 on the side plate 2 facilitate the conveying of the continuous casting.

[0028] Gas is pumped into the circulation pipe 16 by the air pump 14 at the front of the cooling pool 1. Then, the gas is sprayed onto the surface of the workpiece through the nozzle 17 on the circulation pipe 16 to initially cool the workpiece and blow off the oxide layer on the workpiece. Then, water is pumped out of the cooling pool 1 by the water pump 13 and sent into another circulation pipe 16 to cool the workpiece. At the same time, the water is filtered by the screen 22 at the rear end of the water inlet pipe 19. The fan blade 21 drives the sleeve 20 and the screen 22 to rotate, throwing off the impurities blocking the screen 22, thus facilitating the water pump 13 to draw water and thus facilitating the cooling of the continuous casting.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
