[0003] The cloth wind device in the prior art can quickly cool the slag through the ventilation hole, so that the temperature of the slag can be reduced to the allowable temperature range, and the overall structure of the cloth wind device is relatively simple. Since the cloth wind device has multiple ventilation holes with fixed sizes, the amount of cold air entering is fixed and not easy to control. During the operation of the slag cooling bed, the wind cover serves as the inlet for cold air, and the amount of cold air entering will affect the cooling effect of the slag. SUMMARY

DETAILED DESCRIPTION

[0018] The technical scheme in the embodiments of the utility model will be apparently and completely described in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the range protected by the utility model.

[0019] Please refer to Figure 1 And Figure 2It is understood that this utility model provides a technical solution: an air distribution device for a slag cooling bed, comprising: an air hood body 1, ventilation holes 2, and fixed columns 3. The air hood body 1 has ventilation holes 2 at its front, and fixed columns 3 are connected inside the air hood body 1. A U-shaped frame 4 is connected to the top of the air hood body 1. A sliding groove 5 is provided through the interior of the U-shaped frame 4. A threaded column 6 is threaded to the top of the U-shaped frame 4. A rotating ball 7 is welded to the bottom of the threaded column 6. A movable plate 8 is provided on the outside of the rotating ball 7. A transparent baffle 9 is connected to the bottom of the movable plate 8. The movable plate 8 and the U-shaped frame 4 form a sliding structure through the sliding groove 5. A rotating groove matching the size of the rotating ball 7 is provided inside the movable plate 8.

[0020] In practical implementation, the air distribution device for the slag cooling bed is mainly used for slag cooling. The amount of cold air entering the traditional air distribution device is relatively fixed, which affects the cooling effect of the slag. This makes it difficult for the air distribution device to control the air intake according to the amount of slag. When the amount of slag is small, the threaded column 6 can be rotated forward. When the threaded column 6 rotates forward, it can drive the rotating ball 7 to move closer to the wind hood body 1. When the rotating ball 7 moves, it can rotate inside the moving plate 8. At the same time, the rotating ball 7 can push the moving plate 8. When the moving plate 8 moves, it can slide between the slide groove 5 and the U-shaped frame 4. When the moving plate 8 slides, it can drive the transparent baffle 9 to move closer to the front of the ventilation hole 2. When the transparent baffle 9 moves to the designated position in front of the ventilation hole 2, the transparent baffle 9 can block part of the ventilation hole 2. At this time, cold air can be introduced into the wind hood body 1 through the ventilation hole 2, thereby cooling the slag.

[0021] See Figure 1 and Figure 2 It can be seen that by controlling the position of the transparent baffle 9, the air intake of the hood body 1 can be controlled, so that the air distribution device can adjust the air intake of the hood body 1 according to the amount of slag, avoiding the situation where the slag is not cooled evenly or completely due to too much or too little air intake.

[0022] See Figures 1-3 It can be seen that the main body 1 of the wind shroud is connected to a fixed seat 10. The fixed seat 10 has a through groove 11 inside. The fixed seat 10 is connected to a compression spring 12. One end of the compression spring 12 is connected to a semi-circular protrusion 13. An arc-shaped guide plate 14 is provided on the outside of the fixed seat 10. A connecting block 15 is connected to the side of the arc-shaped guide plate 14 near the fixed seat 10. An arc-shaped slot 16 is provided in the interior of the connecting block 15 near the semi-circular protrusion 13. Three sets of arc-shaped guide plates 14 are provided inside the main body 1 of the wind shroud.

[0023] In actual implementation, when the air cooling device for slag cooling bed is used, after the cold air enters the inside of the air cover main body 1 through the air vent 2, the air speed will be reduced, resulting in a large loss of cold air, which will affect the slag cooling effect. The arc-shaped flow guide plate 14 can be moved to the inside of the air cover main body 1 first, and then the arc-shaped flow guide plate 14 is pushed towards the fixed seat 10. When the arc-shaped flow guide plate 14 moves, the connecting block 15 can be moved. When the end of the connecting block 15 is inserted into the fixed seat 10 through the through slot 11, the end of the connecting block 15 will extrude the arc-shaped surface of the semicircular block 13. When the semicircular block 13 is extruded, the compression spring 12 will be compressed. When the compression spring 12 is compressed to the maximum extent, the connecting block 15 can be moved to the deepest part of the through slot 11. At this time, the semicircular block 13 can be moved to the position above the arc-shaped clamping groove 16. When the semicircular block 13 is no longer extruded by the connecting block 15, the compression spring 12 can be reset. When the compression spring 12 is reset, the semicircular block 13 can be reset. When the semicircular block 13 is reset, it can be clamped into the arc-shaped clamping groove 16, thereby fixing the connecting block 15 and the arc-shaped flow guide plate 14.

[0024] Referring to Figures 1-3 It can be seen that when the cold air enters the inside of the air cover main body 1 through the air vent 2, the arc-shaped flow guide plate 14 can guide and convey the cold air, thereby increasing the speed of the cold air flowing in the air cover main body 1, and ensuring that the slag cooling effect is not easily affected.

[0025] In summary, when the air cooling device for slag cooling bed is used, the threaded column 6 can drive the rotating ball 7 to move towards the air cover main body 1 when it rotates in the positive direction. The rotating ball 7 can rotate in the moving plate 8 when it moves, and the rotating ball 7 can push the moving plate 8. By controlling the position of the transparent baffle 9, the air inlet amount of the air cover main body 1 can be controlled, so that the air cooling device can adjust the air inlet amount of the air cover main body 1 according to the amount of slag, so as to avoid the situation that the slag is not uniformly or completely cooled due to too much or too little air inlet amount. When the cold air enters the inside of the air cover main body 1 through the air vent 2, the arc-shaped flow guide plate 14 can guide and convey the cold air, thereby increasing the speed of the cold air flowing in the air cover main body 1, and ensuring that the slag cooling effect is not easily affected.
