Description

Wharf ship unloader with novel dustproof structure unloading hopper

Technical Field

The utility model belongs to the technical field of the technique of pier unloading and specifically relates to a pier ship unloader with novel dustproof construction discharge hopper is suitable for the dustproof of material among the port and pier material handling transportation, the dust that will raise is airtight in a relative confined space, firstly avoids environmental pollution. And secondly, the escape of the particulate materials is reduced, the material loss is reduced, and the economic benefit of the wharf is increased.

Background

At present at the pier in-process of unloading, the operation is usually that ship unloaders (or door machine) snatch the goods from the cabin through the grab bucket of unloading, promote, unload after the transportation in to the discharge hopper, material in the discharge hopper is carried to the stockyard through belt transport mechanism (or tipper) again, at the grab bucket of unloading toward the funnel in-process of unloading, a large amount of materials receive gravity to influence free fall, can carry a large amount of air entering funnel in the material, cause very big malleation environment in the funnel, thereby air current can produce certain ascending thrust, the granule that quality and density are little can be smugglied secretly the suspension in the air, escape to the funnel outer wall, in addition dock environmental wind's influence, it is serious to cause the in-process raise dust of unloading more, the environment worsens.

The operation environment of the wharf is in a full-open type, when the unloading height of the unloading grab bucket is large, the influence of environmental wind force on the unloading of the hopper is more obvious, the traditional dust removal measures are mainly two, one is to install a bag dry dust collector on the hopper, dust raised by an air suction port arranged at the hopper opening of the unloading hopper is sucked into a filter bag for filtering, the dust is filtered and intercepted, and clean and quiet air after filtering is directly discharged into the atmosphere through an air outlet. The other measure is that a windproof wall is additionally arranged at a feeding port of a funnel to reduce the influence of wind power, a plurality of ultrasonic nozzles are arranged at the periphery of the windproof wall and can spray steam-water mixture with small atomized particles, a dense fog pool is formed at the feeding port of the funnel, and steam particles and dust molecules in the fog pool are condensed and fall to achieve the purpose of dust removal.
