Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction at transfer points, in particular to a spray dust reduction device at transfer points. Background Art

[0002] When materials are transferred at bulk cargo terminals, the transfer point has a large drop and is a closed material storage environment, which causes dust to be raised by the belt when it is running. The dust near the entire transfer point is large. Although the head and tail between the transfer stations are closed, the length and distance are limited, and dust still overflows. In addition, the closed area is less affected by wind, and the fine dust inside the belt corridor continues to accumulate, which easily leads to excessive dust concentration inside the corridor, especially near the transfer point. Workers basically work at the head and tail of the transfer point for a long time, which makes them in a dust-hazardous environment for a long time, so dust reduction equipment is needed to reduce dust.

[0003] The existing patent announcement number CN211058855U discloses a spray dust suppression device for mining transport transfer points. By setting a spring switch and an inner core, when the belt is transported to the transfer point for transfer, it will impact the touch plate, and then the touch plate drives the spring rod to move outward, which will drive the bearing to squeeze the extrusion plate. Under the action of the extrusion plate, the inner core of the spring switch acts on the water inlet ball valve to open the pipeline, and water will flow through the water inlet ball valve to the spray device for spraying. When no coal passes through the transfer point, the spring rod returns to normal and the spraying stops.

[0004] When the above device is performing dust reduction work, the dust reduction direction is relatively single, and dust is only reduced in one direction. The materials are of different sizes, and water is easily accumulated on the ground after long-term use. At the same time, the belt is prone to slipping during operation. In view of the above problems, a transfer point spray dust reduction device is proposed. Utility Model Content
