Description

Technical Field

[0001] The utility model belongs to the technical field of coal transportation, in particular to a coal transportation dust suppression device. Background Art

[0002] As the coal is transported on belt conveyors and other equipment, the raw coal blocks will tumble and collide with each other many times. The coal will also collide with the transportation equipment during the process of being thrown and falling to the ground. In this series of actions, the larger particle size fuel blocks will break into small particles of uncertain size, which will spread to the surrounding area with the airflow to form coal dust.

[0003] In order to suppress the dispersion of dust, atomizing nozzles are often installed at a certain interval at both ends of the belt to atomize the surface of the coal. However, the atomization range of the nozzles at a certain interval is limited, resulting in the defect of an atomization blind spot between the two intervals, which makes it difficult to suppress the dispersion of dust. For this reason, we propose a water spray suppression device that can use a swinging nozzle to spray water on the coal between the intervals to reduce the occurrence of atomization blind spots.
