Detailed Description
The technical scheme of the utility model is explained in detail below with the attached drawings:
as shown in fig. 1, when the port door machine grab bucket works, materials fall from the grab bucket to a blanking hopper 200 (installed on a support 100), the falling of the materials can cause disturbance of surrounding air, and disturbed airflow can drive small-particle materials to fly and generate dust when moving. When the mineral powder material falls into the blanking hopper 200, potential energy is released, and the mineral powder material collides with the subsequent falling material after rebounding, so that a large amount of dust is generated at the blanking point. Meanwhile, the materials continuously added in the blanking hopper 200 replace the air in the discharging bin to cause backflushing airflow, so that small-particle materials falling into the storage bin are driven to backflush upwards, and the dust generation at the blanking hopper 200 is aggravated. On the other hand, when loading materials at the loading opening (below the blanking hopper 200), positive pressure is formed around the loading opening due to the fact that the speed of the materials is too high, and therefore dust is diffused around.
