Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a telescopic chute spray dust suppression device. Background Art

[0002] At present, during the loading or unloading process of metallurgical materials such as ore powder, coal powder, sintered pellets, etc., the materials need to be grabbed onto the conveyor belt of the conveying platform, and then transported to the material drop port through the conveyor belt, and then enter the telescopic chute through the material drop port, and fall with the gravity of the telescopic chute; when the drop height exceeds 2 meters, the falling material causes disturbance in the surrounding air, and the disturbed airflow will drive small particles of material to fly and generate dust when it moves;

[0003] The existing technology will set a spray port on the telescopic chute, and spray the falling materials through the spray port to suppress dust. For example, the existing technology discloses a chute spray dust suppression device for a ship loader, with the authorization announcement number CN220617663U and the authorization announcement date 20240319. Although the existing technology can achieve dust suppression effect, it still has the following problems:

[0004] Since the spraying position is at the edge of the telescopic chute, the spray port mainly sprays a circle around the material. Although the small particles on the periphery of the material are absorbed and settled by the water droplets, the spraying method is directly downward and the material falls very fast, resulting in the small particles inside the material not being absorbed by the water droplets. After falling to the bottom, the upper material collides with the lower material. At this time, the small particles that are not absorbed by the water droplets fly up under the action of the collision, and the dust suppression effect is insufficient. Utility Model Content
